BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a print control apparatus for photographic film or the like, and more particularly to a print control apparatus in which a plurality of frames of a photographed film or the like are printed on a sheet of printing paper,
whereby an effect similar to that obtained by effecting multiple exposure in a camera can be obtained.
2. Related Background Art
Multiple photographing mechanisms have heretofore been provided in some of single-lens reflex cameras of which many kinds of specifications are required, but it has scarcely been practiced chiefly for the following reason to incorporate the
multiple photographing function into a lens shutter camera designed with the compactness and economy of the camera as a primary object. In a lens shutter camera, film winding-up and shutter charge can be effected at a time or in association with each
other and therefore, there can be realized a compact, light-weight and highly economical camera, but if an attempt is made to endow, for example, a full automatic lens shutter camera having an auto focus mechanism with the multiple photographing
function, it becomes necessary that film winding-up and shutter charge and charging of the auto focus mechanism be effected discretely, and this results in the remarkable complication, bulkiness and increased cost of the camera, which in turn has
resulted in a loss of compactness of economy which are merits intrinsic to a lens shutter camera. Therefore, there have scarcely been realized lens shutter cameras capable of multiple photographing.
Also, when multiple photographing is to be effected, various judgments must be formed during photographing, such as changing the exposure per one cycle of photographing depending on the number of cycles of multiple photographing, and keeping the
exposure as it is when the background is dark, and it has been impossible to effect multiple photographing readily. Further, during multiple photographing, one mistake has affected printing results.
SUMMARY OF THE INVENTION
The present invention has been made in view of the above-noted circumstances, and intends to provide a camera provided with setting means for setting multiple printing information and recording means for recording the multiple printing
information set by said setting means and which can achieve multiple printing by a simple construction without causing bulkiness and increased cost.
Also, the present invention intends to provide a camera which is provided with reading means for reading the multiple printing information recorded by said recording means and control means for effecting multiple printing in conformity with the
multiple printing information read by said reading means and which can achieve multiple printing by a simple construction without causing bulkiness and increased cost.

The electrical circuit of the above-described camera will now be described with reference to the circuit diagram of FIG. 3. In FIG. 3, SW1 designates a photometry switch adapted to be closed by the first-stage depression of the release button 3
shown in FIG. 1, SW2 denotes a release switch adapted to be closed by the second-stage depression of the release switch 3, SW.sub.A designates a multiple switch adapted to be closed by the depression of the multiple setting button 4, and SW.sub.B denotes

Description will hereinafter be made of the operation when photographing is effected by the camera of the above-described construction. When multiple printing is to be designated, the multiple setting button 4 is first depressed. Thereupon, in
the circuit of FIG. 3, the multiple switch SW.sub.A is closed, and for example, one of the light-emitting members 14 (in the present embodiment, the lowermost light-emitting member 14 in FIG. 2) is turned on for a moment through the displaying
microcomputer DMC and the LED driving circuit LEDR. At this time, the display of PRINT or the like appears on the liquid crystal display device LCD, whereby the turn-on of the light-emitting member 14 can be confirmed. Thereupon, as shown in FIG. 4,
that portion of the film 16 which is opposed to the light-emitting member 14 is exposed, and a code C.sub.1 is recorded on the film 16. Thereafter, the release button 3 is depressed to close the photometry switch SW.sub.1 and the release switch
SW.sub.2, thus effecting the photographing operation. That is, the code C.sub.1 at the left of the first frame F.sub.1 photographed corresponds to this frame F.sub.1. Subsequently, the multiple setting button 4 is depressed with the object changed or
with the composition changed for the same object by a similar operation, thereby effecting photographing again. Thereupon, the same light-emitting member 14 as that previously mentioned emits light again to the photographed second frame F.sub.2, and the
code C.sub.1 is recorded. On the third frame F.sub.3, photographing has been effected without the multiple setting button 4 being depressed but with only the release button 3 being depressed because multiple printing is not desired, and a code
corresponding to this frame F.sub.3 is not recorded at all.
When the photographer changes his mind and desires to cancel the multiple printing information after he has effected photographing by depressing the multiple setting button 4 as previously described, he can depress the cancelling button 5 before
he shifts to the next photographing operation. That is, as shown in FIG. 5, the light-emitting member 14 is turned on at a point of time whereat the multiple setting button 4 has been depressed, and the code C.sub.1 is recorded on the left side of a
frame F.sub.4. Subsequently, the exposure of the frame F.sub.4 is completed, and a motor, not shown, is driven by the motor driving circuit MD, whereby the film 16 is wound up. Thus, the next frame F.sub.5 becomes opposed to the aperture 13 of the
camera. When at this point of time, the cancelling button 5 is depressed by the tip or the like of a nail, the cancelling switch SW.sub.B is closed and the light-emitting member 15 is turned on for a moment. Thereupon, that portion of the film 16 which
is opposed to the light-emitting member 15 is exposed, and a code C.sub.2 is recorded on the film 16. Here, when the code C.sub.2 has been recorded, the frame preceding it (in the present embodiment, the frame F.sub.4) is designed to indicate that it is
not associated with multiple printing.
Further, in the above-described embodiment, it is of course possible to effect a plurality of different multiple printings in a single film. In that case, it is necessary to make the codes different, and one of the light-emitting members may be
caused to emit light at a time. An example of such a code is shown in Table 1 below, and in the present embodiment, fifteen multiple printings are made possible in a single film by 4-bit codes.
TABLE 1 ______________________________________ Code Photographing Mode ______________________________________ 0000 normal photographing 0001 multiple printing (1st time) 0010 multiple printing (2nd time) 0011 multiple printing (3rd time)

Here, "1" shows that a light-emitting member 14 to which that bit corresponds is turned on, and "0" shows that a light-emitting member 14 to which that bit corresponds is turned off. g
The operation of the circuit of FIG. 3, including what has been described above, will now be described in greater detail with reference to a flow chart regarding the displaying microcomputer DMC of FIG. 6. Here, a flow chart regarding the
controlling microcomputer CPU is not shown, but this may be a known one and is therefore omitted herein for simplicity.
In FIGS. 3 and 6, at #1, the state of the cancelling switch SW.sub.B is first input from an input terminal IB At #2, whether the cancelling switch SW.sub.B is ON or OFF is checked, and if it is ON, advance is made to #3, where a cancellation code
is imprinted into the film for a predetermined time, and advance is made to #4, and if the cancelling switch SW.sub.B is OFF, advance is directly made to #4 without the intermediary of #3. At #4, the state of the multiple switch SW.sub.A is input from
an input terminal I.sub.A, and at #5, whether the multiple switch SW.sub.A is ON is checked. If it is ON, the multiple mode is entered and advance is made to #6, where the state of the counter switch SW.sub.C shown in FIG. 3 is input from an input
terminal I.sub.D. At #7, whether this counter switch SW.sub.C is operated is judged, and if it is operated, at #8, the set counter value is re-set to a value counted up by one and advance is made to #9, and if the counter switch SW.sub.C is not
operated, advance is made to #9 with the counter value unchanged. This counter value is indicative of the group of frames for which it is desired to effect multiple printing on the same printing surface, and as shown in Table 1 , grouping can be done up
to fifteen groups by said counter value. When said counter value is counted up by the counter switch SW.sub.C and reaches the upper limit value, it returns to the initial value and thus, the counter value can be set by being circulated in succession.
At #9, the set counter value is displayed on the display device LCD by the display driving circuit LCDR. At #10, the imprint signal from the controlling microcomputer CPU is input from an input terminal I.sub.C At #11, the presence or absence of
the imprint signal is checked, and if the imprint signal is present, advance is made to #12, where any code in Table 1 which corresponds to the counter value is imprinted on the film by the light-emitting member 14, and return is made to #1. If at #11,
the imprint signal is absent, return is directly made to #1. When at #5, the multiple switch SW.sub.A is not ON, that is, when the mode is not multiple photographing, advance is made to #13, where the display on the liquid crystal display device LCD by
the display driving circuit LEDR is turned off, and return is made to #1 and the imprinting of codes is not effected.
The construction of a printing apparatus suitable for the camera as described above which automatically performs the printing operation of printing the photographed film on printing paper is shown in FIG. 7. In FIG. 7, A designates a printing
apparatus, and B denotes a RAM card for memorizing the codes recorded on the film. In the printing apparatus A, EL designates a printing lamp, ELDR denotes a lamp control circuit for controlling the turned-on/turned-off state of the printing lamp EL,
and CL designates a condenser lens. The light emitted from the printing lamp EL is applied to a film F lying at the printing position through the condenser lens CL and a proper color filter EF. The light transmitted through the film F is projected onto
printing paper PP on a roll through a printing zoom lens PL, whereby printing is effected. Also, the construction of FIG. 7 is controlled by CPU as shown in FIG. 8.
The detailed construction of this printing apparatus and the operation thereof will hereinafter be described with reference to the flow chart of FIG. 9.
In FIGS. 7, 8 and 9, at #101, the film F is wound up by a film feeding device FTR. In the course of this winding-up, at #102, the code recorded on the film F is read by a data code reading device READ. Design is made such that when at this
time, the code C.sub.2 as shown in FIG. 5 has been read, the multiple information of the frame preceding it is cancelled. Subsequently, at #103, the frame number and the code data corresponding thereto are memorized into the RAM of RAM card B. At #104,
whether the data memorization has been completed is confirmed, and if it is completed, advance is made to #105, where the rewinding of the film F is started, but if data memorization is not completed, return is made to #103. At #106, the printing paper
PP is fed onto the optic axis of the printing lamp EL in synchronism with the movement of the film F, and design is made such that at this time, a printing paper feeding device PTR moves the printing paper PP on the roll to a proper position.
Subsequently, at #107, data is read out from the RAM card B, and at #108, the presence or absence of the multiple code is confirmed, and if the multiple code is present, at #110, the feeding of the printing paper PP is stopped, and if the multiple code
is absent, at #109, the printing paper PP is moved by an amount corresponding to one frame of the film F, and advance is made to #113 which will be described later. At #111, the same multiple code is searched from the data memorized in the RAM card B.
This is because if the multiple code has been found out, there is one or more of the same multiple codes beside it. If at #112, there is the same multiple code, advance is made to #113, where a film having the same multiple code is set in the printing
apparatus and the film F is stopped from moving, and advance is made to #114. When at #112, the same multiple code has been finished, advance is made to #118.
At #114, the printing lamp EL is turned on for a predetermined time by the lamp control circuit ELDR. At #115, the number of times of multiple printing and the exposure condition are determined by a photometry/colorimetry circuit, not shown, and
at #116, a shutter ESH disposed in front of the printing paper PP is opened by a shutter control circuit ESHDR and an image is printed on the printing paper PP, and then the shutter is closed, whereby the exposure is completed. At #117, the turn-on of
the printing lamp EL by the lamp control circuit ELDR is stopped, and return is made to #111, where the search as to whether there is the same multiple code is repeated.
At #118, whether the frames of the film F to be printed have been finished is confirmed, and if said frames are finished, the flow is brought to an end, and if said frames are not finished, return is made to said #106.
As is apparent from the foregoing description, for example, during the printing of the frames F.sub.1 and F.sub.2 shown in FIG. 4, the feeding of the printing paper is once stopped and printing of a plurality of images is effected on the same
printing paper. Thus, a print P.sub.1 shown in FIG. 10 is obtained from said frames F.sub.1 and F.sub.2, and this has an effect similar to that obtained by effecting multiple photographing by the camera. At. #114 in the flow chart of FIG. 9, the number
of times of multiple printing is taken into account for determining the exposure condition, and this is for shortening the printing time of each frame in the case of multiple printing as compared with the case of normal printing, to thereby preventing
the finished print from becoming overexposed.
Another embodiment of the present invention will now be described.
FIG. 11 is a perspective view of a camera according to the present embodiment. In FIG. 11, the reference numeral 101 designates a camera body, the reference numeral 102 denotes a photo-taking lens, the reference numeral 103 designates a release
button, the reference numeral 104 denotes a multiple setting button, and the reference numeral 105 designates a cancelling button for cancelling multiple setting. The cancelling button 105 is made small so as not to be depressed by mistake and is
designed so as to be depressed, for example, by a nail. S designates a printing density selecting member. The printing density selecting member S is for excessively imparting a quantity of printing light to one of the frames to be multiple-printed
during printing each time photographing is effected, in order to make said one frame to be more impressive and more conspicuous than the other frames, or conversely reducing the quantity of printing light for said one frame in order to make the frames
more conspicuous, and S is a member for selecting and setting the printing density. Divisions such as +1, 0 and -1 are formed near the printing density selecting member S, and when the printing density selecting member S is positioned at the division
+1, it means that a quantity of printing light greater by +1 step than a proper quantity of printing light is imparted, and when the printing density selecting member S is positioned at the division 0, the proper quantity of printing light is imparted,
and when the printing density selecting member S is positioned at the division -1, it means that a quantity of printing light smaller by 1 step than the proper quantity of printing light is imparted. LCD' designates a liquid crystal display device for
displaying the information during printing. The liquid crystal display device LCD' is disposed on the upper surface of the camera body 101. FIG. 13 shows a state in which will displays are displayed. FIG. 12 is a plan view of the camera body 101 as
seen from its back, and shows the camera body with its back panel removed to facilitate description. In FIG. 12, the reference numeral 106 designates a cartridge chamber for containing a film cartridge therein, the reference numeral 107 denotes inner
rails for controlling the position of the film in the direction of the optic axis, and the reference numeral 108 designates outer rails for controlling the position of the film in a vertical direction. The reference numeral 109 denotes a spool chamber,
and the reference numeral 110 designates a film take-up spool. The reference numeral 111 denotes a finder, and the reference numeral 112 designates a back panel groove in which a back panel, not shown, is fitted. The reference numeral 113 denotes an
aperture, and the reference numeral 114 designates a plurality of (in the present embodiment, four) light-emitting members provided near the aperture 113 for imprinting multiple printing information as a code into the film. The reference numeral 115
denotes a light-emitting member for imprinting a code for cancelling the multiple printing information into the film. SD1 and SD2 designate light-emitting members adapted to emit light by the movement of a printing density selecting member S. The
light-emitting members SD1 and SD2 are for imprinting the prinitng density as a code into the film. Such light-emitting members 114, 115, SD1 and SD2 may be, for example, light-emitting diodes.
The electrical circuit of the camera according to the present embodiment will now be described with reference to the circuit diagram of FIG. 14. In the construction of FIG. 14, members similar to those in FIG. 3 are given similar reference
numerals. In FIG. 14, SW1 designates a photometry switch adapted to be closed by the first-stage depression of a shutter release button 103 shown in FIG. 13, SW.sub.2 denotes a release switch adapted to be closed by the second-stage depression of the
shutter release button 103, SW.sub.A designates a multiple switch adapted to be closed by the depression of a multiple setting button 104, and SW.sub.B denotes a cancelling switch adapted to be closed by the depression of a cancelling button 105. SWSO,
SWSP and SWSU designate switches adapted to be closed when the printing density selecting member S is positioned at divisions +1, 0 and -1, respectively. One of the switches SWSO, SWSP and SWSU is adapted to be selectively closed. CPU' denotes a
controlling microcomputer which governs the control of the camera of the present invention, and DMC' designates a displaying microcomputer for controlling the display of the liquid crystal display device LCD' and also controlling the code imprinted into
the film with the counter function. LCDR' denotes a liquid crystal driving circuit for controlling the liquid crystal display device LCD', and LEDR' designates an LED driving circuit for controlling the turn-of/turn-off of said plurality of
light-emitting members 114 and 115.
E denotes the power supply battery of the camera, and the output thereof provides a power source terminal E.sub.1 stabilized through a stabilizing circuit comprising a diode D and a capacitor C, and is supplied to the controlling microcomputer
CPU' and the displaying microcomputer DMC'. AE designates a photometry calculation circuit. Information DX regarding the film speed pre-memorized in the film cartridge inserted in the camera is introduced into the photometry calculation circuit AE. SH
denotes a shutter control circuit, and MD designates a motor driving circuit for controlling a film winding-up motor, not shown.
The operation of effecting photographing by the camera of the above-described construction will hereinafter be described with reference to the flow chart of FIG. 18. When multiple printing is to be designated, the multiple setting button 4 is
first despressed. Thereupon, in the circuit of FIG. 14, as shown at #301 of FIG. 18, the multiple switch SW.sub.A is closed, and as shown at #302-#303, the displaying microcomputer DMC' starts, and as shown at #304, for example, one of the
light-emitting members 114 (in the present embodiment, the lowermost light-emitting member 114 in FIG. 12) is turned on for a predetermined time through the LED driving circuit LEDR'. At this time, as shown at #306 and #307, the liquid crystal display
device LCD' starts, and as shown in FIG. 13, the display of MULTI appears, whereby it is confirmed that the light-emitting member 114 has been turned on. That is, as shown in FIG. 15, that portion of the film 116 which is opposed to the light emitting
member 114 is exposed, and a code C.sub.21 is recorded on the film 116.
Further, depending on the position of the printing density selecting member S, one of the switches SWSO, SWSP and SWSU is closed, and as shown at #320-#324, #330-#334 and #340-#344, a high level is input to one of the input terminals I.sub.C,
I.sub.D and I.sub.E of the displaying microcomputer DMC', and corresponding one of OVER, PROPER and UNDER is displayed on the liquid crystal display device LCD'. When the shutter release button 103 is depressed to close the photometry switch SW1 as
shown at #350, a high level is input to the input terminal I.sub.21 of the controlling microcomputer CPU' as shown at #351-#354, whereby the photometry calculation circuit AE is operated and the output value, the shutter time and the aperture value
photometry-calculated thereby are input to the controlling microcomputer CPU' through the terminal I.sub.3 thereof. When the shutter release button 103 is further depressed to close the release switch SW.sub.2 as shown at #355-#359, an aperture control
circuit, not shown, is operated and a predetermined aperture value is reached, whereafter the shutter control circuit SH is operated through an input terminal O.sub.23 and at the same time, starts from a terminal O.sub.24, and light emission and display
are effected by the light-emitting members SD1 and SD2 and the liquid crystal display device LCD' as shown in Table 2 below.
TABLE 2 ______________________________________ LCD State of switches Displayed Light-emitting members SWSO SWSP SWSU characters SD1 SD2 ______________________________________ ON OFF OFF OVER Light Light emission emission OFF ON OFF
PROPER Light Non-light emission emission OFF OFF ON UNDER Non-light Light emission emission ______________________________________
Subsequently, as shown at #360-#361, a predetermined time elapses and imprinting is completed, whereafter a high level is input as a turn-off signal to a terminal I.sub.25, and as shown at #362-#366, the film winding-up motor control circuit MD
is operated to start film winding-up and at the same time, a charge mechanism for the shutter, the mirror, etc. is operated, and after the completion of these operations, a high level is input to a terminal I.sub.6, and as shown at #367-#370, the
controlling microcomputer CPU' starts to thereby start the displaying microcomputer DMC' and the character OVER, PROPER and UNDER are turned off. When multiple printing is to be effected on the next frame, return is made to #301 and the same operation
as that described previously is performed. FIG. 15 shows the photographed film 116, and the actual photographing operation will hereinafter be described. FIG. 16 is a view of the film as seen from the back of the emulsion surface thereof. First, the
multiple setting button 104 is depressed and a code C.sub.21 is imprinted. Next, during the shutter release, supposing a case where a person is superposed on the landscape, for example, a recollected scene of the person is printed on the landscape, the
photographer imprints a code C.sub.21 for instructing to print the landscape with a printing density one step under a power printing density so that the landscape does not abstruct the person. At this time, the printing density selecting member S is
positioned at the division -1. Subsequently, after film winding-up, it is assumed that the person is to be photographed on the next frame. In this case, the photographer has the intention of printing the person with a printing density greater than that
for the landscape and therefore, the photographer positions the printing density selecting member S at the division +1 and imprints a code C.sub.22 for instructing to print the person with a printing density +1 step over. The third frame F.sub.23 is a
frame on which photographing has been effected without the multiple setting button 104 being depressed but with only the release button 103 being depressed because multiple printing is not desired for this frame, and no code corresponding to this fame
F.sub.23 is recorded. In this case, the multiple setting button 104 is not depressed and therefore, if the printing density selecting member S is positioned at any of the divisions +1, 0 and -1, the printing density instructing code is not imprinted.
As the proper density during said multiple printing, where multiple printing is effected on a sheet of printing paper by the use of n frames, the time for one printing should desirably be 1/n of the time required in the case of printing using one
frame.
A case where multiple information is cancelled will not be described with reference to the flow chart of FIG. 10. When as previously described, the photographer changes his mind and desires to cancel the multiple information of this frame after
he has depressed the multiple setting button 104 to effect photographing, he depresses the cancelling button 105 before he shifts to the next photographing operation. That is, as shown in FIG. 16, at the point of time whereat the multiple setting button
104 has been depressed, the light-emitting member 114 is turned on and a code C.sub.21 is recorded at the left of the frame F.sub.4. Subsequently, during the exposure of the frame F.sub.4, a code C.sub.21 of one-step under printing is imprinted
depending on the position of the density selecting member S, and after the completion of the exposure, a motor, not shown, is driven by the motor driving circuit MD, whereby the film 116 is wound up. Thus, the next frame F.sub.25 becomes opposed to the
aperture 113 of the camera. When at this point of time, the cancelling button 105 is depressed as by the tip of a nail, the cancelling switch SW.sub.B is closed as shown at #380, and as shown at #381-#383, the displaying microcomputer DMC' starts up and
the light-emitting member 115 is turned on for a predetermined time. Thereupon, that portion of the film 116 which is opposed to the light-emitting member 115 is exposed and a code C.sub.22 is recorded on the film 116. At the same time, CANCEL is
displayed on the liquid crystal display device LCD', as shown in FIG. 13. Here, design is made such that when the code C.sub.22 has been recorded, it is indicated that the frame preceding it (in the present embodiment, the frame F4) is not associated
with multiple printing.
Further, in the above-described embodiment, it is of course possible to accomplish a plurality of different multiple printings in a single film. In that case, it is necessary to make the codes different, and as previously described, the
light-emitting member 114 may be selectively caused to emit light, or a plurality of light-emitting members selected may be caused to emit light at a time. An example of such a code is shown in Table 3 below, and in the present embodiment, by a 4-bit
code, fifteen multiple printings are made possible in a single film.

Here, "1" shows that a light-emitting member 114 to which that bit corresponds is turned on, and "0" shows that a light-emitting member 114 to which that bit corresponds is turned off.
The operation of the circuit of FIG. 14, including what has been described above, will now be described in detail with respect discretely to the operation conformity to the flow chart of FIG. 20 regarding the controlling microcomputer CPU' and
the operation conformity to the flow chart of FIG. 21 regarding the displaying microcomputer DMC'.
First, in FIGS. 14 and 20, at #401, the state of the photometry switch SW1 is input from an input terminal I.sub.21, and at #402, whether the photometry switch SW1 is ON or OFF is discriminated, and if it is OFF, return is made to #401, where the
operation is repeated, and if it is ON, advance is made to #403, where a photometry starting signal is sent from an output terminal O.sub.21 to the photometry calculation circuit AE. At #404, the object luminance information measured by the photometry
calculation circuit AE is input from an input terminal I.sub.23. Subsequently, at #405, the state of the release switch SW.sub.2 is input from an input terminal I.sub.22, and at #406, whether the release switch SW.sub.2 is 0N or OFF is checked, and if
it is OFF, return is made to #401, and if it is ON, advance is made to #407. At #407, a code imprint starting signal is output from an output terminal O.sub.24 to the displaying microcomputer DMC', and at #408, the imprint completion signal of the
displaying microcomputer DMC' is input from an input terminal I.sub.25, and if at #409, the imprinting is completed, advance is made to #410. At #410, the object luminance information input at #404 is sent from an output terminal O.sub.23 to the shutter
control circuit SH, and at #411, the exposure completion signal by the shutter control in the shutter control circuit SH is input from an input terminal I.sub.4, and if at #412, the exposure is completed, advance is made to #413, where a winding-up start
signal is output from an output terminal O.sub.25 to the motor driving circuit MD. At #414 and #415, the winding-up completion signal from the motor driving circuit MD is checked from an input terminal I.sub.21, and if winding-up is completed, advance
is made to #416, where a signal for turning off the display is output from an output terminal O.sub.26 to the displaying microcomputer DMC', and return is made to #401 and the sequence is repeated again. If winding-up is not completed, return is made to
#414.
Next, in FIGS. 14 and 21, at #501, the state of the cancelling switch SW.sub.B is input from the input terminal I.sub.B, and if at #502, the cancelling switch SW.sub.B is ON, at #503, an output is made to the display driving circuit LCDR' so as
to display CANCEL on the liquid crystal display device LCD', and then advance is made to #504, and if the cancelling switch SW.sub.B is OFF, advance is made from #502 to #504. At #504, the state of the multiple switch SW.sub.A is input from the input
terminal I.sub.A, and if at #505, the multiple switch SW.sub.A is OFF, advance is made to #516, and if the multiple switch SW.sub.A is ON, at #506, a signal is output to the display driving circuit LCDR' so as to display MULTI, and advance is made to #A,
on the basis of Table 3, a counter value for designating the group of frames on which multiple printing is to be effected in conformity with the ON or OFF of the multiple frame group setting switch SW.sub.C shown in FIG. 14 is set from the input terminal
I.sub.F.
Advance is then made to #B, where the counter value of #A is displayed on the liquid crystal display device LCD', and to what multiple printing of Table 3 it corresponds is displayed, and advance is made to #507. At #507, the state of the switch
SWSO is introduced from the input terminal I.sub.C, and at #508, whether the switch SWSO is ON or OFF is discriminated. If it is ON, at #509, a signal is sent to the display driving circuit LCDR' so that OVER is displayed, and advance is made to #510,
and if the switch SWSO is OFF, advance is directly made to #510 without the intermediary of #509. At #510, the state of the switch SWSP is input from the input terminal I.sub.D, and at #511, whether the switch SWSP is ON or OFF is discriminated, and if
it is ON, at the next #512, a signal is output to the display driving circuit LCDR' so that PROPER is displayed, and advance is made to #513, and if the switch SWSP is OFF, advance is directly made to #513 without passing through #512. At #513, the
state of the switch SWSU is input from the input terminal I.sub.E and at the next #514, whether the switch SWSU is ON or OFF is discriminated, and if it is ON, at the next #515, a signal is sent to the display driving circuit LCDR' so that UNDER is
displayed, and advance is made to #516, and if the switch SWSU is OFF, advance is directly made to #516. At #516, the imprint starting signal from the output terminal O.sub.4 of the controlling microcomputer CPU' is input, and at the next #517, the
presence or absence of the imprint starting signal is checked, and if this is present, advance is made to #518, and if this signal is absent, return is made to #501 and the above described sequence is repeated. In the foregoing description, at #509,
#512 and #515, one of OVER, PROPER, and UNDER is selectively displayed and the displays which have not been selected are turned off.
Subsequently, at #518, a signal is sent to the LED driving circuit LEDR so that codes conforming to the states of the switches SW.sub.B SW.sub.A, SWSO, SWSP and SWSU are imprinted onto the film surface, and the light-emitting member is turned on
for a predetermined time, whereby the codes are imprinted. | | |
