Reference numeral 51 denotes a display unit on which a product sample is displayed; and 52, a panel on which product selection buttons are arranged. 53 is a slot for receiving coins and bills, 54 is a display for displaying the deposit amount,
55 is a product take-out door. The above is the configuration of the general vending machine. Further, the display unit 51 is provided with an LED display 56 on the upper part of the display unit 51, and various commercial messages and simple animations can be displayed.

[0019] FIG 2 is a control block diagram of a vending machine V ₁ showing one embodiment of the first aspect of the present invention.
1 is a CPU for controlling sales, and 2 is a CPU.
A ROM 1 stores a control program to be executed.
Reference numeral 3 denotes a RAM for temporarily storing data relating to sales. 4 is a sales control unit that performs control relating to the merchandise, as shown in FIG. 1, it sells 16 kinds of items Q ₁ to Q _16, thus the column C ₁ of 16 groups which contained the product, respectively
To C ₁₆ (not shown).

The above-mentioned display device 56 is provided with a display device 10 indicated by a broken line, and in addition to the display device 56, a CPU 11 for controlling display on the display device 56 is provided. It has a ROM 12 for storing a basic program for the display, a RAM 13 for storing display data to be displayed on the display 56 and the display program.

[0021] Conventionally, display operation in the display device 10, but independent control of the vending machine V _1, in the present invention, an output port 5 to CPU1 for sale controller, the display device 1
0 is provided with an input port 14 and these output ports 5
Interconnecting the input port 14 in a parallel signal line L ₁ and.

Then, the sales data (sold out, poor sales, etc.) and control contents (such as sold out and poor sales) in the sales control unit 4 are reflected in the display of the display device 10 so that the sales situation and the various situations of the control contents at the vending machine V ₁ are reflected on the display of the display device 10. The setting of the sales time in the case of heating / cooling, liquor sales, etc.) is recognized by the situation recognizing unit 1A. Pn is designated via the signal line L _1. If the signal line L ₁ is constituted by 8 lines, you can specify 2 ⁸ = 256 kinds of ports.

On the other hand, the CPU 11 of the display device 10 has a change display section 11A, and the RAM 13 always displays contents (advertises not directly related to individual sales merchandise, for example, a sales maker which has conventionally been displayed. in addition to the messages M ₀ ad), a message Mn corresponding to the various conditions (port) (up to 256 species) are stored.
Thus, for example, the port Px is designated, the display change section 11A, read a message Mx corresponding thereto, display on the display unit 56 is changed to Mx from M _0.

FIG. 3 shows the display 5 when there is a product whose sales are sluggish.
6 shows a flow of displaying a sales promotion message for the product. Thus where the port P ₁ to P ₁₆ sales slump to correspond to each product Q ₁ through Q ₁₆ is designated, to the product Q ₁ no correspond to those of a port P ₁ to P ₁₆ message appeal to Q ₁₆ It is assumed that M ₁ to M ₁₆ are stored.

When a predetermined amount of money is received, the process proceeds from step S1 to step S2, and when the product selection button is pressed here,
The product corresponding to the product selection button is carried out in step S3, and change is refunded in step S4.

In step S5, the number of stocks in the column storing the products sold this time is reduced by one, and
At 6, the sales analysis means 1A analyzes the sales status of each column. For example, sales of goods Q ₃ is the sales is analyzed poor below 70 present in a week, the port P ₃ through the signal line L ₁ is specified in step S7, sales standby state thereafter returns to step S1 Becomes

On the other hand, in the display device 10, it is determined in step S11 whether there is an external connection. If there is no external connection, that is, if the display device 10 is used alone, the process proceeds to step S13, where the message M ₀ is read, and the message M ₀ is displayed on the display 5 in step S15.
6 is displayed.

If there is an external connection, the process proceeds from step S11 to step S12, and it is determined whether a port is specified. If no port is specified, the process proceeds to step S13. If a port is specified, the process proceeds to step S14.
Message M ₃ is RAM corresponding to the specified port P ₃
Is read from the 13, display on the display unit 56 is changed from the message M ₀ to the message M _3.

When the display of this message is effective and all the products are sold well, step S7
, For example, the port P ₀ is turned on. As a result, in the display device 10, from step S12 to step S12
13, the message M ₀ is read,
Return to the original display mode.

[0030] In the flow of FIG. 3, when there is a commodity Q ₃ of sluggish sales, the product Q ₃ in place of the message M ₀ of the display at all times
The but it was to switch to a message M ₀ to appeal various display forms are conceivable besides it.

For example, usually, M ₀ (15 seconds) → M ₁ (5 seconds)
→ M ₂ (5 seconds) → M ₃ (5 seconds) → M ₄ (5 seconds) →… M ₁₆ (5 seconds) →
Each message is sequentially displayed at a timing such as M ₀ (the display period is shown in parentheses). However, if the sale of the product Q ₃ is poor, M ₀ (15 seconds) → M ₁ (5 seconds) → M
₂ (5 seconds) → M ₃ (10 seconds) → M ₄ (5 seconds) →… M ₁₆ (5 seconds) → M
_{0 ...} as of, the message display of goods Q ₃ of the sales failure is long. In this way, the display timing and display pattern can be arbitrarily changed according to the sales situation. Since the number of characters (16 × 16 dots) that can be displayed on the display 56 is not so large, a message M
_{When 1} to M ₁₆ are displayed by flowing from right to left like an electronic bulletin board, the message M ₃ may be displayed twice or three times in succession.

Although the flow of FIG. 3 is to display a sales promotion message for a poorly sold product, a sold-out display can be reflected on the display device 10.
For example the port P ₂₁ to P ₃₆ corresponding to the sold out of the product Q ₁ through Q ₁₆ is specified by the port designation, as message display flag for each item is cleared to "0" to "1" In advance, only the message of the product with the message display flag of “1” may be displayed. Therefore, for example, when the product Q ₃ is sold out, M ₀ (15
Second) → M ₁ (5 seconds) → M ₂ (5 seconds) → M ₄ (5 seconds) →… M ₁₆ (5 seconds)
→ A message of only products that can be sold in a pattern such as M ₀ is displayed.

In addition, in order to discount the selling price during the campaign, conventionally, a method of attaching a seal to the vending machine to show that the campaign is being performed has been adopted, but a large-area display 56 is used. The campaign can be effectively appealed. Port P ₄₁ corresponding to each product Q ₁ to Q ₁₆ discounting the selling price
To specify the P _56, Accordingly, the RAM 13, to Kiyanpen message M ₄₁ not corresponding to P ₅₆ to no port P ₄₁ stores the M _56, may be appropriately display the campaign message.

[0034] In the liquor sales, if sales stop time zone, past, simply had a sold-out display of all products, for example, specify the port P _57, Along with this RAM36
The corresponding port P _57, stores the message M ₅₇ indicating the sales stop, by the port designation, for example, the bottom of the message M ₀ in the display, to display a message M ₅₇ indicating the stop selling By doing so, a kind guidance display can be performed for the user.

[0035] FIG. 4 is a control block diagram of a vending machine V ₂ showing one embodiment of the second aspect of the present invention, for the same elements as in FIG. 2 are denoted by common reference numerals. In FIG. 4, output port 5 and input port 1 of FIG.
4, a vending machine dedicated communication interface 6,
With 15, and you can communicate bidirectionally connected between the two interfaces with the serial communication line L _2.

A command is used in place of the port designation in accordance with various situations such as a sales situation or control contents in a vending machine, and a message corresponding to each command is stored in the RAM 13 of the display device 10. By doing so, the same control as the vending machine in FIG. 2 can be performed. FIG. 5 is a flowchart corresponding to FIG. 3, in which commands are used in step S7 ′ and step S12 ′ instead of port designation.

In the communication interface used here, a character code can be transmitted in addition to the command. In the vending machine V ₁ shown in FIG. 2, the campaign message discounting the sale price, for example, "new product Cola sale! At 80 yen" need to be stored to items Q ₁ the contents, such as 16 species in each Q ₁₆ However, the product name and price are input from the keyboard of the vending machine, and the character code is displayed on the display device 1.
0, and store it in the RAM 13, the campaign message is “New product *** is **
Available for sale in yen! The message can be handled by one message as shown in FIG.

Since the vending machine V ₂ of FIG. 4 is a bidirectional communication means, when a failure related to display occurs on the display device 10 side, the failure information is sent from the CPU 11 of the display device 10 to the vending machine V _2. of by sending to the CPU 1, will be able to manage the operation state of the display device 10 in the vending machine V ₂ side, thus when downloading sales data or the like from the vending machine V ₂ using the data loader and the like, wherein Of the display device 10
Can be easily managed.

Since the display 56 has a large area, it is possible to display a game on the display 56 and play the game there. For example, in the case of a roulette game, a roulette pattern is displayed on the display 56, and each "piece" of the roulette is sequentially turned on at a constant speed at the start of the game. Decide. In order to display such a roulette, it is only necessary to store a roulette display program and data in the RAM 13, and it is not necessary to install hardware for a game machine.

FIG. 6 shows control on the display device 10 when a roulette game is provided. When selling signals with the payment and sales output vending machines is supplied, the process proceeds from step S51 to step S52, the roulette game is displayed read from RAM13 instead the message M ₀ being displayed on the display unit 56 In step S53, the pieces are sequentially lighted and moved by the game start. In step S54, the stop time is calculated from the generated random numbers. When the stop time is reached, the movement of the piece is stopped in step S56, and in step S57, it is determined whether or not the piece is hit or out of position. By sending a pseudo deposit signal to the vending machine side in step S58, the extra sale is permitted. Step S59
Back to the display of the original message M _0.

[0041] As an automatic vending machine V ₂ in communication means of Figure 4 described above, since a dedicated communication interface 6, which is standard on the vending machine of the present invention can be implemented in addition of the minimal hardware .
