At the rear of this control table 1a, there is provided a display or exhibition device 3 which stands upright.

The exhibition device 3 comprises a display panel 4 carrying 68 representations 5 which are disposed in plural rows. Each representation 5 consists of a title of a software program and an animated cartoon or pictorial or illustrative image showing the contents or subject matter of the program. The individual programs indicated by the respective representations 5 are numbered by Serial-No. indicia 6 disposed right above the corresponding representations 5. In this specific embodiment, Serial Nos. 1-20, 21-40, 41-60, and 61-68 respectively designate: software programs for video games (hereinafter referred to as GAME programs); software programs for business purposes (hereinafter referred to as BUSINESS programs); software programs for educational purposes (hereinafter referred to as EDUCATIONAL programs); and such GAME, BUSINESS and/or EDUCATIONAL programs which are newly marketed products. Thus, these software programs identified by the representations 5 and designated by the Serial-No. indicia 6 are classified into three groups, i.e., GAME, BUSINESS and EDUCATIONAL, each group consisting of programs having utilities in the same category. The new software programs, Serial Nos. 61-68 include the GAME, BUSINESS and EDUCATIONAL programs arranged at random.

The exhibition device 3 includes indicator lights 7 (FIG. 4) provided on the inner side of the display panel 4, so as to be located right behind the respective Serial-No. indicia 6. These lights 7 are illuminated under the control of central processing means which will be described.

As illustrated in FIG. 2, the control table 1a has a visual display device in the form of a cathode ray tube 8 (hereinafter called CRT 8) having a screen which is covered by a transparent glass plate 9. This CRT 8 provides messages to a purchaser, displays the contents of each program on sale, and serves other functions, as discussed later in detail. The control table 1a further has numeric Ten-keys 10 disposed to the right of the CRT 8 to select a desired one of the 68 software programs through their serial numbers given by the Serial-No. indicia 6. At the back of the numberic Ten-keys 10 is provided a speaker 11 which is adapted to generate sounds for video games, alarm sounds, etc.

In front of the Ten-keys 10, there are disposed a START key 12 to execute the selection of a program which has been designated by the Ten-keys 10, and a RESET key 13 which is used to cancel the selection of a program once effected by depression of the START key 12. Three selector switches are provided in front of the START and RESET keys 12, 13: a GAME selector key 14; a BUSINESS selector key 15; and an EDUCATIONAL selector key 16. These selector keys 14, 15 and 16 are used to designate one of the three groups of software programs: GAME, BUSINESS: and EDUCATIONAL. Thus, the numeric Ten-keys 10, and the selector keys 14-16 serve as selector means for selecting a desired software program.

In front of the CRT 8, there are disposed manually-operated means: a pair of joy stick switches 17, and four joy keys 18 located between the switches 17. These switches and keys 17, 18 are used to interact with a selected program when it is executed on the CRT 8, or influence the execution of the program, in particular, to participate in a game which is animated by the selected program executed on the CRT 8. In other words, the manipulation of the switches 17 and keys 18 will affect visual images provided on the CRT 8 during execution of the program.

To the left of the CRT 8, there are provided cash-depositing means: a paper-money inlet 19 through which a 1000-yen bill is inserted into the instrument 1; a 100-yen coin slot 20 through which a 100-yen coin is deposited; and a 10-yen coin slot 21 for depositing a 10-yen coin. An indicator 22 disposed to the left of the 100-yen coin slot 20 indicates the sum of money deposited through the paper-money inlet 19 and the 100-yen and 10-yen coin slots 20, 21. The indicator 22 further indicates the serial number of a program designated by the Ten-keys 10, and other information. At the back of the indicator 22 is disposed a receipt exit 23 through which is fed out a receipt which is printed by a printer which will be described.

The control table 1a is further provided, at the back of the receipt exit 23, with a tape cassette recording/playback device 24 which is used, as one of recording means, by the purchaser to inspect or verify a program bought by the purchaser. The recording/playback device 24 is operated through manipulation of a REWIND key KY1, a STOP key KY2, a PLAY key KY3, a FAST FORWARD key KY4 and a RECORDING key KY5, which are all disposed on the front side of the device 24. An indicator, "COPY" light PL1 is disposed on the rear side of the recording/playback device 24. This "COPY" light PL1 is illuminated while a selected program is duplicated into a recording medium in the form of a tape cassette 25 of FIG. 3. The blank or non-recorded tape cassette 25 is stored in the vending instrument 1 in large quantities.

On the front left-hand side of the vending instrument 1, there are disposed a cassette tray 26 and a change tray 27. The cassette tray 26 receives the recorded tape cassette 25, and the change tray 27 receives change when the amount of money deposited through the inlet 19 and the coin slots 20, 21 exceeds a selling price of a program duplicated into the tape cassette 25.

The host system 2 includes a printer 28, a CRT 29, and a keyboard 30. The printer 28 is used to produce a printout of sales record of each software program sold by each local dealer, including dates of sales of the programs. The CRT 29 is used to display such sales records.

Referring next to FIG. 4, a control arrangement of the software vending system of the invention will be described below.

In the figure, the host system 2 comprises a central processing unit 37 (hereinafter referred to as host CPU 37) which is connected to a first central processing unit 41 hereinafter referred to first CPU 41) of each peripheral vending instrument 1 at the local dealer, through a MODEM interface 38, a MODEM interface 39 provided for the instrument 1 and a private or exclusive data communication line connecting the two MODEM interfaces 38 and 39, whereby interactive data communication between the host system 2 and the instrument 1 can be effected. The host system 2 further comprises primary memory means in the form of a magnetic disk memory 40 which has: a first memory area for storing source programs corresponding to the 68 programs which are exhibited on the display panel 4; a second memory area for storing price data indicative of selling prices of the programs; and a third memory area for storing sales data representing the sales records of the individual programs sold by each peripheral vending instrument 1, including the date of sale (year, month and day). The loading of source programs and the their price data into the respective first and second memory areas of the disk memory 40 is effected by personnel of the software manufacturer, supplier or distributor. The third memory area for the sales records has divided memory locations for the individual vending instruments 1, and each of these memory locations is divided into sections for different dates of sale of each one of the 68 programs on sale. Thus, the number (and amount) of sale of each program by each instrument 1 is recorded in the third memory area of the magnetic disk memory 40.

The peripheral vending instrument 1 comprises central processing means which consists of the previously introduced first CPU 41 and a second central processing unit 42 (hereinafter called second CPU 42). The first and second CPUs 41, 42, which serve various control functions including verification of a sold program, are adapted to exchange data to each other and operate according to a predetermined main program. The first CPU 41 receives data or signals from the host CPU 37 and the input devices such as the keys and switches previously described, and further receives command signals from the second CPU 42, which in turn receives command signals from the first CPU 41.

The first CPU 41 is connected to three secondary memory means in the form of random-access memories 43, 44a, and 44b. These first, second and third secondary memory means 43, 44a and 44b are hereinafter referred to as "DEMONSTRATION DISPLAY" RAM 43, "PROGRAM DISPLAY" RAM 44a and "COPY" RAM 44b.

The "DEMONSTRATION DISPLAY" RAM 43 stores: plural sets of demonstration data corresponding to the 68 software programs exhibited on the display panel 4; message data representing messages to the purchaser; and price data indicative of the selling prices of the programs. The demonstration data represents an abstract of the contents of the respective software program. These demonstration, message and price data are transferred to the CRT 8 to provide a demonstration display of a selected program, and to display selling messsages and prices.

The "PROGRAM DISPLAY" RAM 44a is to operate the CRT 8. When a software program is designated through the selector switches 14-16 and the Ten-keys 10, the designated program data is transferred from the magnetic disk memory 40 to the "PROGRAM DISPLAY" RAM 44a through the host CPU 37 and the first CPU 41. The first CPU 41 retrieves the program data from the "PROGRAM DISPLAY" RAM 44a and transfers it to the CRT 8 so that the selected program is executed on the CRT 8, that is, the first CPU 41 causes the CRT 8 to display the contents of the program, for example, enables a corresponding video game to be played on the screen of the CRT 8 if the selected program is a video game program.

The "COPY" RAM 44b stores, like the "PROGRAM DISPLAY" RAM 44a, a software program transferred from the magnetic disk memory 40. Further, when the program is transferred from the disk memory 40 to the "COPY" RAM 44b, the demonstration data stored in the "DEMONSTRATION DISPLAY" RAM 43 is transferred to the "COPY" RAM 44b. The selected program data and its demonstration data stored in the "COPY" RAM 44b are retrieved by the second CPU 42, which operates another recording means in the form of an automatic recording device 45 incorporated in the instrument 1, so that the selected program is copied or duplicated in the blank tape cassette 25. More specifically stated, the duplicating device 45 records a duplicate program (together with its demonstration data) in one of the blank tape cassettes 25 stored in the instrument 1, based on signals from the second CPU 42. After completion of the program loading into the tape cassette 25, the tape is rewound and the cassette 25 is ejected to the cassette tray 26.

A paper-money detector 46 and a coin detector 48 are provided to detect bills (paper-money) and coins deposited through the paper-money inlet 19 and the coin slots 20, 21. Signals from these detectors 47, 48 are applied to a counter 48 which counts the sum of the deposited money, and feeds "deposit" data to the first CPU 41.

Depending upon the "deposit" data from the counter 48 in comparison with the appropriate price data, the first CPU 41 directs the second CPU 42 to retrieve the selected program and its demonstration data stored in the "COPY" RAM 44b and to operate the automatic recording device 45 to duplicate the retrieved program and the demonstration data into the tape cassette 25, as described later in detail. Further, the first CPU 41 causes the indicator 22 to display the sum of the deposited money based on the "deposit" data, and controls a receipt printer 49 built in the instrument 1 to print out a receipt.

The first CPU 41 controls a light energization circuit 50 which energizes a group of the 68 indicator lights 7 corresponding to the group of programs selected by the GAME, BUSINESS and EDUCATIONAL selector switches 14-16, and effects a flickering or blinking operation of a particular one of the indicator lights 7 corresponding to a specific program selected by the Ten-keys 10. A D/A (digital/analog) converter 51 is connected to the first CPU 41 to covert a digital control signal of the first CPU 41 into an analog signal which is amplified by an amplifier 52 and transferred to the speaker 11, so that the speaker 11 generates video game sounds and alarm sounds.

Referring to flow charts of FIGS. 5-9 illustrating the sequence of control by the first and second CPUs 41, 42, there will be described the operation of the vending instrument 1 which is constructed as discussed hitherto. For easier understanding, steps of operations are numbered in the flow charts, and the step numbers (preceded by letter S) are referred to in the following description.

Upon turning on a power switch (not shown) on the instrument 1 (S1), the first CPU 41 is placed into its operative state wherein on-line interactive data communication with the host CPU 37 is possible through the private communication line. In this state, the first CPU 41 is ready to accept an input by a purchaser through operation of the GAME, BUSINESS and EDUCATIONAL selector switches 14, 15 and 16 (S1-S3).

When the purchaser depresses the GAME selector key 14 (S2) to buy a GAME program for a video game, for example, the first CPU 41 operates as shown in FIG. 5. At first, the first CPU 41 activates all of the indicator lights 7 that correspond to all GAME programs (serial numbers 1-20, and some of the new programs, serial numbers 61-68 which are GAME programs), whereby the appropriate Serial No. indicia 6 on the display panel 4 are illuminated to indicate the program representations 5 of the GAME program group (S4).

Then, the purchaser enters, with the Ten-keys 10, a serial number corresponding to a desired one of the GAME programs whose representations 5 are illuminated by the indicator lights 7 on the display panel 4. As soon as the desired GAME program has been designated (S5), the serial number of the GAME program is indicated on the indicator 22 (S6), and the first CPU 41 waits for the activation of the START key 12. In response to an ON signal generated from the START key 12 upon depression thereof (S7), the first CPU 41 causes only the indicator light 7 corresponding to the designated serial number, to blink or flicker (S8). In the meantime, the first CPU 41 reads out from the "DEMONSTRATION DISPLAY" RAM 43 the designated program, its demonstration data and price data, and transfers them to the CRT 8 (S9). The demonstration data represents an abstract of the subject matter of the designated program, more particularly, visual images to provide a brief demonstration of the contents of the program, e.g., abstract views of a video game played by the selected GAME program.

According to the demonstration data, demonstration images are displayed on the CRT 8. Simultaneously, the CRT 8 indicates a selling price of the program according to the price data, and provides a message "Please deposit money if you wish to buy this program." according to the message data (S9). Consequently, the purchaser is able to decide whether to buy the program which has been designated, by observing the demonstration images and the selling price information provided on the CRT 8.

While the demonstration images are viewed on the CRT 8, the first CPU 41 waits for the activation of the RESET key 13 (S10) or the deposit of money (S11). When the purchaser wishes to cancel the designated program, that is, wishes to see demonstration images of another program, the RESET key 13 is depressed. In this instance, the first CPU 41 stops the demonstration on the CRT 8 and the flickering operation of the indicator light 7 corresponding to the program which has been demonstrated on the CRT 8 (S12). Then, the first CPU 41 becomes ready to accept the input of a serial number of another program (S5).

On the other hand, when the purchaser deposits a cash through the paper-money inlet 19 and/or coin slots 20, 21, the first CPU 41 compares the "deposit" data from the counter 48 with the price data read out from the "DEMONSTRATION" RAM 43 (S11). If the sum of the deposited cash is equal to or greater than the predetermined selling price of the designated program, the first CPU 41 changes the preceding message on the CRT 8 to a message "Thank you very much." (S13), and activates the receipt printer 49 to print out a receipt, which is then fed to the receipt exit 23 (S14). In the case where the comparison of the "deposit" data with the price data indicates an overpayment by the purchaser, the appropriate amount of change is supplied to the change tray 27 (S14).

Although the designated program is subsequently duplicated into the tape cassette 25 as described later, the activation of the START key 12 and the deposit of enough amount of money (confirmed by the counter 48) are required conditions for initiating the duplication (sale) of the program which has been designated by the Ten-keys 10. In other words, the central processing means 41, 42 of the instant embodiment checks to see if the START key 12 and the counter 48 have been placed in the predetermined positions, before the designated program is duplicated in the tape cassette 25. The START key 12 and the counter 48 are used as means for checking if the conditions required for vending a program have been satisfied or not. The central processing means 41, 42 serve to inhibit the duplicating device 45 from duplicating the selected program in the tape cassette 25 until the START key 12 and the counter 48 have been placed in their predetermined positions. The activation of the START key 12 means the final selection by the purchaser of the program, and the payment confirmed by the counter 48 indicates the final decision of the purchaser to buy the program.

After the receipt has been printed out by the printer 49, the first CPU 41 sends a command signal to the host CPU 37 through the private line, directing retrieval of the designated program from the magnetic disk memory 40 and transfer of the retrieved program to the "PROGRAM DISPLAY" RAM 44a and the "COPY" RAM 44b. (S15-FIG. 6). In response to the command signal, the host CPU 37 retrieves the appropriate source program from the disk memory 40 and transfers the same to the first CPU 41 through the private communication line. The first CPU 41 then stores the program temporarily in the "PROGRAM DISPLAY" RAM 44a and the "COPY" RAM 44b. Subsequently, the first CPU 41 retrieves from the "DEMONSTRATION DISPLAY" RAM 43 the demonstration data corresponding to the program stored in the RAMs 44a, 44b, and stores the retrieved demonstration data into the "COPY" RAM 44b (S15).

In the meantime, the second CPU 42 retrieves the selected program and its demonstration data from the "COPY" RAM 44b, and operates the automatic duplicating device 45 to duplicate the retrieved program and the demonstration data in the blank tape cassette 25 (S16). As soon as the duplication of the program has been started, the first CPU 41 energizes the "COPY" light PL1 (S16) to inform the purchaser that the selected program is under duplication.

After the illumination of the "COPY" light PL1, the first CPU 41 retrieves the program from the "PROGRAM DISPLAY" RAM 44a, and operates the CRT 8 to execute the program while the program is being duplicated (S17). In this specific example wherein the program is a GAME program, the corresponding video game is played or an
