BACKGROUND OF THE INVENTION
The present invention generally relates to a disk playing apparatus which
makes it possible to play a plurality of optical disks called compact
disks, and/or disks of different diameters.
For example, an ordinary disk (hereinafter referred to as a CD) of 12 cm in
size, and the small-diameter disk (hereinafter referred to as a CD single)
of 8 cm in size, are generally used as compact disks. In recent years, the
use of CD players has spread considerably. CD players of not only a
stationary type, but also a portable type and a car-loading type have been
extensively marketed. In addition to the disks of 12 cm, the CD singles of
8 cm have appeared, and are expected to increase remarkably in popularity
in the future. At the beginning, CD players adopted a method of playing
the CDs with adapters being provided for CD singles. But direct play
thereof is gradually increasing, without the adapters, in terms of
improvements in operability, with this tendency increasing especially in
car-loading CD players. Also, a change type of player has increased in
popularity because of its superior operability and because the disks are
drawn one by one from an exclusive magazine, which has many disks therein
to be played.
Especially in the CD players for car-loading use, the CD single measure
without the adapters is behind, because the disk engagement method of a
front loading system is used more due to the use thereof within the car.
Measures to cope with this problem are desired. Also, even in the change
type of CD players, the measures the CD singles have to take are behind,
with problems that a setting location is restricted in terms of the size
of the main body.
SUMMARY OF THE INVENTION
Accordingly, the present invention has been developed with a view to
substantially eliminating the above discussed drawbacks inherent in the
prior art disk playing apparatus, and has the essential object of
providing an improved change type of disc playing apparatus, taking
advantage of the merits of the prior art disc playing apparatus.
Another object of the present invention is to provide a change type of disk
playing apparatus which is capable of using both CDs and CD singles in a
front loading system.
Still another object of the present invention is to provide a change type
of disk playing apparatus which is reduced in size by the use of a
magazine for CD singles.
In accomplishing these and other objects, according to one preferred
embodiment of the present invention, the disk playing apparatus is
characterized in that the disk musical performance position is constructed
obliquely and rearwardly with respect to a magazine storing position for
CD singles.
Also, the disk playing apparatus of the present invention is characterized
in that in the above described construction, an insertion opening for
loading a CD is provided above or below the magazine storing position.
Also, the disk reproducing apparatus of the present invention is
characterized in that in the above described construction, a disk feed
roller is provided which is adapted to effect a vertical disk movement
operation from the magazine, and to effect a pivoting movement around a
shaft provided on a stationary base plate upon disk movement from the
direct insertion opening.
The present invention has an advantage in that in the accommodation of a
magazine of CD singles into the space restricted space of a DIN size of
car-loading use, the musical performance position is arranged obliquely
and rearwardly with respect to the accommodation position, so that the
space may be effectively used and the function of the auto-changer
operation may be used.
Also, the present invention has an advantage in that a change function by
the magazine and a direct insertion opening for a CD or a CD single are
provided, so that only one loading of an ordinary disk may be effected,
and continuous play by the magazine and play from the direct insertion of
a disk without the use of the magazine may both be effected.
For both the change operation and the direct insertion with the vertical
movement and the pivoting operation one set of rollers is used, with an
advantage in that the number of components may be reduced and space may be
saved, as compared with cases where separate exclusive rollers are
respectively arranged.

DETAILED DESCRIPTION OF THE INVENTION
Before the description of the present invention proceeds, it is to be noted
that like parts are designated by like reference numerals throughout the
accompanying drawings.
Referring now to the drawings, there is shown in FIGS. 1 and 2 the
relationship between a magazine of a CD player and a disk musical
performance position according to one preferred embodiment of the present
invention. FIG. 1 shows a condition of a 1DIN size CD player seen from
above. FIG. 2 is a side view thereof. The CD player, as the disk playing
apparatus of the present invention, includes a traverse mechanism 1, which
effects ordinary traverse operations such as disk rotation, optical pick
up movement, and so on, so as to read the signals of the disk faces, and a
mechanism base plate 2 with various mechanism components mounted on it. A
damper rubber 3 is fixed on the base plate 2, is engaged with the traverse
mechanism 1, and is provided with a buffer function so that impacts and
oscillations may not be transmitted to the traverse mechanism. A roller
arm or retaining member is disposed for vertical operations on the base
plate 2, and causes the disk to move by a roller rotating operation with a
pressure grip of a pair of rollers 4a and 4b, and has a guide member
built-in in the roller arm 4 so that the disk won't be shaken vertically
when the disk is grasped between the rollers and overhangs during the
horizontal movement of the disk. A magazine 5 with three CD singles stored
therein has disk take-out levers 5a, 5b and 5c arranged corresponding to
each disk of the three CD singles so as to have a function of causing the
disk to be engaged between the rollers by a pushing operation in the arrow
mark direction. The traverse mechanism 1 and the magazine 5 are composed
diagonally in the 1DIN size, and the roller arm 4 is obliquely arranged
between the traverse mechanism and the magazine. Referring to FIG. 2,
reference numeral 6 is a first disk stored in the upper stage of the
magazine 5, reference numeral 7 is a second disk stored in the
intermediate stage thereof, and reference numeral 8 is a third disk which
is stored in the lower stage. Reference numeral 9 is a clamp which relates
to a centering ring la of the traverse mechanism 1 by being attracted
thereby and a magnet so as to effect a disk clamping operation when the
disk is engaged. By the pushing operation of the disk take-out lever 5a of
the magazine 5, the disk 6 is projected out of the magazine 5 so that the
disk is grasped between the passive roller 4a and the driving roller 4b.
The disk 6 effects a horizontal movement onto the right hand side by the
clockwise rotation of the driving roller 4b. The rotation of the driving
roller 4b is stopped in a position where the disk has been drawn
completely out of the magazine 5. The roller arm 4 is then caused to
effect a downward movement with the disk 6 grasped between the rollers.
The disk 6 is caused to come to a stop in a position where it may be
engaged with the centering ring 1a. Thereafter, the passive roller 4a
moves upwardly and the driving roller 4b moves downwardly, so so to
release the CD single so that the CD single can be played. In this case,
the clamp 9 is in a position above the disk drawn out from the magazine 5,
and descends according to the downward movement of the disk, or after the
movement. Also, after the disk has been clamped onto the traverse
mechanism 1 by the clamper 9, the rollers 4a and 4b move in the separating
direction as noted above, to allow the disk to be rotated. The
construction as described hereinabove allows the magazine 5 to be
completely accommodated in the panel within the space of the 1DIN, and
simplifies the operation necessary for the drawing out of the disk.
FIG. 3 is a plan view showing a case where a direct insertion may be
effected by a front loading operation in the construction described in
FIG. 1 and FIG. 2. FIG. 4 shows a front panel in this case. Referring to
FIG. 3, the roller arm 4 is in a lateral condition due to rotation in a
counter-clockwise direction around a pivoting shaft 4c from the condition
of FIG. 1. The roller arm 4 has been lowered down to a position where it
is not in contact with the magazine 5, even in the vertical direction.
Referring to FIG. 4, there is a direct insertion opening 10 provided in a
location corresponding to the above described position of the roller arm
4, and a magazine storing opening 11 constructed above the direct
insertion opening. Also, a button A in FIG. 4 is provided to select a
disk. The button switches between playing the disk inserted from the
direct insertion opening 10 or playing a disk provided within the magazine
5 of the magazine storing opening 11. Every time the button A is
depressed, the condition is alternately switched. For example, the change
from FIG. 1 condition of the roller arm 4 to FIG. 3 condition is also
effected by the depressing operation of the button A. When the button A is
depressed in the condition of the roller arm 4 of FIG. 1, the condition of
the roller arm 4 is provided as shown in a solid line of FIG. 3. When the
button A is depressed again, the original condition of FIG. 1 is provided
by the reverse operation. In case a disk 13 or 14 has been inserted into
the direct insertion opening 10 in the condition of FIG. 3, the insertion
disk 13 or 14 is detected by a photo-sensor B1 or B2 provided near the
insertion opening 10, the rotation of the pair of rollers 4a and 4b of the
roller arm 4 starts, and the disk horizontally moves as far as the
constant position by a method to be described later. Also, the roller arm
4 is rotated in the clockwise direction by a switch (not shown) for
detecting the insertion of the magazine 5 into the magazine storing
opening 11 (or by the depression of the above described button A) from the
condition of FIG. 3, and returns to the first condition again, so that
disk engagement from the magazine 5 may be effected. In the construction
described above, by the vertical movement and the pivoting operation of
the roller arm 4, the arm 4 may be used for disk engagement both from the
magazine 5 and from the direct insertion opening 10. The number of parts
may thus be reduced and space saved. Two methods of effecting musical
performance may be properly used, the CD single may be inserted from the
direct insertion opening 10 and stored in the magazine 5, and the reverse
operation thereof may be effected.
FIG. 5 shows a method of discriminating between the CD and the CD single.
Reference characters 12a and 12b are 8 cm-12 cm detection guides, and
operatively cooperate with the roller arm 4 so as to stop the advance of
the inserted disk with the roller arm 4 being lateral. Also, the detection
guide 12b is adapted to externally escape or move aside as shown in broken
lines in FIGS. 6 and 7, to be described later, with a shaft 12d of the
base portion of an arm 12c being a center when the roller arm 4 pivots in
the clockwise direction as shown in FIG. 1 so as not to come into contact
against the disk. Also, the 8 cm-12 cm detection guides 12a and 12b are
disposed one by one, right and left, in such a manner as to come into
contact with the external periphery of the CD 13. When the CD 13 has been
inserted in the above described construction, the CD 13 is moved in an
arrow mark direction, and thereafter is stopped by the 8-12 detection
guides 12a and 12b. Also, when the CD single 14 has been inserted, the CD
14 is likewise moved in the arrow mark direction, and thereafter is
stopped in a position with the CD single being grasped between the 8-12
detection guides 12a and 12b. When the CD single 14 has been inserted in a
position shifted right or left, the CD single 14 finally stops in the same
position, receiving a directional correction by the 8-12 detection guides
12a and 12b. The roller of the roller arm 4 which is used in this case is
narrower in the diameter at the central portion thereof as compared with
both ends thereof, and the grasped CD single is thus likely to move
towards the center. Accordingly, as each disk stops at a constant
position, a portion where only either of the CD 13 and the CD single 14
exists is provided. Three photo-sensors B1, B2 and B3 are disposed in the
positions shown, so that a discriminating operation may be effected, and
whether the disk inserted from the insertion opening is a CD or a CD
single is determined. Namely, when the photo-sensor B3 at the tip end has
detected a disk, it is determined that the CD single 14 has been inserted
into its final position, with only the sensor B3 detecting a disk. When
only the sensor B2 detects a disk and the sensors B1 and B3 do not detect
a disk, it is determined that the CD 13 has been inserted into its final
position.
FIG. 6 shows the operation in the case of a CD after the discrimination
operation of FIG. 5. The roller arm 4 effects its pivoting operation in
the clockwise direction with the pivoting shaft 4c being provided as a
center, and with the CD 13 remaining grasped between the rollers 4a and 4b
of the roller arm 4 and moves to the position shown in broken lines. By
the pivoting operation, the guide 12b from the 8-12 detection guides 12a
and 12b moves so as to not come into contact with the disk in the position
after the pivoting operation. By the rotation of the rollers 4a and 4b of
the roller arm 4, the horizontal movement of the disk is again effected.
The rotation is stopped when the musical performance position is reached,
and the clamp 9 is lowered relative to the traverse mechanism 1 so that
the CD 13 is grasped by the centering ring 1a and the clamp 9 in an
engagement condition.
FIG. 7 shows the operation in the case of a CD single after the
discriminating operation of FIG. 5. The roller arm 4 pivots in the
clockwise direction into the condition shown in broken lines with the
pivoting shaft 4C as a center, and the CD single 14 remaining grasped by
the rollers 4a and 4b of the roller arm 4. By the pivoting operation, the
guide 12b of the 8-12 detection guides 12a and 12b moves so as not to come
into contact with the disk in the position after the pivoting operation.
At this time, the original positions of the 8-12 detection guides 12a and
12b are set with respect to the traverse mechanism 1 so that the position
of the CD single 14 after the pivoting operation thereof may become an
engagement position. Thus by lowering the clamp 9 relative to the traverse
mechanism 1 after the pivoting operation of the roller arm 4, the CD
single 13 may be grasped by the centering ring 1a and the clamp 9 into the
engagement condition. By the construction described above, the
discriminating operation between a CD and a CD single may be effected, and
the engagement operation may be effected in accordance with either of the
respective disks.
FIG. 8 and FIG. 9 show a construction for preventing the double insertion
of a disk during the musical performance or playing of a CD. FIG. 8 shows
a condition where the disk may be inserted. FIG. 9 shows a condition where
the disk is prevented from being inserted. In FIG. 8, the reference
numeral 15 is a prevention lever, which is mounted for its vertical motion
on the mechanism base plate 2, and is subject to a spring urging force in
the upward direction or is regulated in operation in the lateral
direction. When the roller arm 4 is located in a position corresponding to
the insertion opening as shown in FIG. 3, the prevention lever 15 is in an
engagement relation with respect to the roller arm 4, and is held in a
lowered position with respect to the spring urging force. Therefore, when
the disk 13 or 14 is inserted from the direct insertion opening 10, it may
reach between the rollers 4a and 4b of the roller arms 4. In FIG. 9, when
the roller arm 4 is in such a position as shown in FIG. 1, the roller arm
4 is released from engagement with the prevention lever 15, and the
prevention lever 15 is then raised upwardly by the spring urging force. At
this time, the prevention lever 15 closes the disk passing range of the
direct insertion opening 10. Accordingly, the prevention lever 15 prevents
a loading from being effected if a disk is tried to be inserted. In the
construction described above, when a CD or CD single is being played, or
during a change operation, a roller arm 4 is in the condition of FIG. 1.
The condition where the direct insertion may be effected is provided only
in FIG. 3, so that the prevention of insertion of a CD or CD single is
otherwise provided. Therefore, the simple construction as described
hereinabove may prevent a double insertion during a musical performance or
a change operation.
FIG. 10 and FIG. 11 show a method of effecting the disk loading operation
by the difference between a traverse mechanism fixing and a floating
condition. FIG. 10 shows the fixing condition of the traverse mechanism.
FIG. 11 shows the floating condition of the traverse mechanism. In FIG.
10, reference numeral 16 is a stationary lever, which is disposed for
pivoting operation on the mechanism base plate 2 so that the traverse
mechanism 1 may be downwardly depressed. Reference numeral 17 is a
stationary guide, which is mounted on the mechanism base plate 2 so as to
secure the traverse mechanism 1, with a stationary pin 1b of the traverse
mechanism 1 being grasped between a V shaped groove portion and the
stationary levers 16. Reference numeral 18 is a spring, with the traverse
mechanism 1 being suspended therefrom. Since the traverse mechanism 1 is
downwardly depressed in the condition of FIG. 10, it is possible to move
the disk horizontally so as to arrange it on the centering ring 1a of the
traverse mechanism 1. Then, the stationary level 16 is upwardly pivoted as
shown in FIG. 11 so as to release the stationary pin 1b of the traverse
mechanism 1, so that the traverse mechanism 1 is upward moved by the
springs 18 into the floating condition and is stable in a position
balanced by the springs 18. After the traverse mechanism 1 has been
raised, the disk is put into the engagement condition by the centering
ring 1a and the clamp 9. by the construction as described above, the
movement of the disk allows the engagement operation only in the
horizontal direction, and further, the space which is provided with the
degree of freedom necessary for the floating operation may be effectively
used.
FIG. 12 through FIG. 14 show an embodiment of the present invention which
saves space about the disk engagement from the magazine. FIG. 12 shows a
draw-out operation and the horizontal movement of the disk from the
magazine. FIG. 13 shows a descent of the disk and a horizontal movement
after the descent. FIG. 14 shows the positions of the CD and the CD single
in the disk engagement position, and the magazine. Reference numeral 19
are upper guide pins, or a first guide, which are provided to stop, in a
setting position, the horizontal movement of the CD single drawn out from
the magazine 5. Reference numeral 20 are lower guide pins, or a second
guide which are provided to stop the CD single in the engagement position.
The lower guide pins 20 are adapted to move away so as not to come into
contact against the CD single in the musical performance condition. In
FIG. 12, the disk 6, which has been drawn from the magazine 5 in a method
similar to that of FIG. 2, effects a horizontal movement in the direction
of the arrow mark by the rotation of the rollers of the roller arm 4 to
come into contact against the upper guide pins 19 so as to come to a stop.
The rotation of the roller is stopped through detection by a switch, a
photo-sensor or the like, or through a time setting. In FIG. 13, the disk
6 grasped by the rollers 4a and 4b of the roller arm 4 moves from the
position of the broken line to the position of the solid line by the
descending operation of the roller arm 4, and further effects the
horizontal movement in the direction of the arrow mark by the reverse
rotation of the driving roller 4b to come into contact against the lower
guide pin 20 so as to come to a stop. The rotation of the driving roller
4b is also detected by the switch, the photo-sensor or the like as in the
draw-out operation from the magazine 5. The solid line 6 in FIG. 14 shows
the position of the disk 6 (CD single) in the musical performance
condition. Also, where the CD 13 is engaged from the insertion opening,
the playing position is as shown in the drawing. As compared with FIG. 2,
where the plane condition of the position shown in the broken line, with
the disk 6 being lowered from the height of the magazine 5, is provided as
the engagement position, the space necessary for the engagement and
musical performance of the CD 13 may be reduced in the present embodiment.
In FIG. 14 the outer periphery of the CD 13 is adjusted to the position of
the broken line of the disk 6, so that the lower space of the magazine 5
may be used more effectively.
In order to effect an initial resetting operation in the construction as
described above, when the power supply has been reconnected again after an
interruption of the musical performance due to a power shut off or the
like, the disk 6 shown in the solid line in FIG. 13 is further moved
horizontally in the arrow mark direction by the roller arm 4, and is
discharged from the direct insertion opening 10 shown in FIG. 4. When the
controlling operation is effected in this manner, the discriminating
operation between the disk taken out from the magazine 5 and the disk
inserted from the direct insertion opening 10, and the discharging
operation thereof, are not necessary to be effected when the power supply
has been put into work again, thus simplifying the controlling operation.
As described hereinabove, the present invention has an advantage in that
the construction of the disk musical performance position is constructed
diagonal with respect to the magazine accommodating position for the CD
singles to allow the effective use of the space and the use of the
functions of the auto-changer in the storing operation of the magazine of
the CD single in the restricted space of the DIN size for car loading use.
Also, the insertion opening for loading the CD in the upper portion or the
lower portion of the magazine storing position is provided to make it
possible to have the change function by the magazine, to have the direct
loading of the CD, and to have both the continuous playing from the
magazine and playing by the direct insertion of CDs without the use of the
magazine.
Also, one set of rollers may be used both for the change operation and for
the direct insertion due to the vertical motion and the pivoting
operation, with an advantage in that the number of components may be
reduced and space may be saved as compared with a case where a roller is
disposed exclusively for each respective operation.
With the disk guide member, provided forwardly in the roller feed
direction, each of the CD and the CD single has its movement stopped in a
given position by the disk guide member an electrical or mechanical
detection is effected by the difference between the stop positions, with
the advantage that it is easier to discriminate between the types of the
disks.
The amount of rotation of the rollers, i.e. the amount of the feed of a
disk, and the position of the guide member for positioning for the
performance of a CD or CD single are selected by electrical or mechanical
methods in accordance with the type of disk, i.e. or a CD or CD single.
The operative cooperation of the disk insertion preventing member with the
pivoting member of the roller prevents the double insertion of a disk
during an operation, such as during a disk musical performance, during a
drawing-out operation of a disk from the magazine or the like.
Since a disk which has been drawn out from the magazine is discharged from
the direct insertion opening during an initial resetting operation,
despite that the disk was drawn out of the magazine or the disk was
inserted from the direct insertion opening, the accommodation position of
the original disk does not need to be electrically or mechanically stored,
with the advantage that the number of components may be reduced, and that
the initial resetting control may be simplified.
The musical performance position of a CD single, with respect to the
accommodating position of the magazine for CD single use, may be a
position where the disk is horizontally drawn out from the magazine,
thereafter moved vertically, and further horizontally moved in the
direction of the magazine, thus making the amount of space necessary
smaller.
The traverse mechanism can be fixed at a lowered position when loading.
When the engagement operation of the disk horizontally moves the disk, the
traverse mechanism can be released so that the traverse mechanism is
raised to effect a clamping operation of the disk, and at the same time be
put into a floating condition having a degree of lateral, longitudinal
freedom, thus making it possible to effect a stable musical performance
free from sound skipping from car oscillations, with the further advantage
that the overall operation is simplified and space saved.
Although the present invention has been fully described by way of example
with reference to the accompanying drawings, it is to be noted here that
various changes and modifications will be apparent to those skilled in the
art. Therefore, unless otherwise such changes and modifications depart
from the scope of the present invention, they should be construed as
included therein.
