DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a pricing system for vending machines that utilizes semiconductor memory.

BACKGROUND OF THE INVENTION Conventional vending machines that set the selling price of products in a semiconductor memory display products that can be sold for the amount put in during a sales operation, as shown in Japanese Patent Application Laid-open No. 13391/1983. Equipped with a sales availability indicator and a mode changeover switch, the price setting mode is specified by this switch, the sales price to be set is inputted using the sales price input device, and the set sales price is stored in memory by operating the selection switch. At the same time, a configuration is shown in which the specified product is displayed on the sellable display corresponding to the specified product.This allows you to check the product corresponding to the number of people set on the sellable display when setting the price. This is to prevent mistakes.

Problems to be Solved by the Invention However, although some vending machines generally sell products at a single price, many vending machines sell all types of products, so there is no need to place a vending machine near the product selection button or near the displayed product. A display section was provided to display the selling price of the product.

This display section is generally a price display card with the selling price written on it, so even if you have set the price correctly, unless you change this price display card, it will not be possible to sell it correctly. It's something that doesn't exist. Changes to the price display card are often forgotten when changing prices, and troubles often occur between vending machine users and managers.

In view of the above-mentioned problems, the present invention provides an entire price setting method for a vending machine that eliminates the need to change the price card and allows easy confirmation of the set price and the corresponding product.

Means for Solving the Problems The present invention provides a display means for electrically displaying the sales price for each type of product, and a memory that stores the price set in the price setting mode. Also, the selling price is displayed on the display means.

In each of the operation price setting mode and the sales operation mode, the information can be read out from the memory and displayed on the display means.

Embodiment FIG. 1 is a block diagram showing the circuit configuration of a vending machine according to the present invention. 1 calculates the input amount based on the input money signal C for each monetary type, and calculates the amount of change after the sale. 2 is a memory having a sales price storage area corresponding to each product to be sold; 3 is a sales possibility display means having a display for displaying the sales possibility for each product; 4 is a display device for displaying the sales possibility for each product; Sales drive means for driving the product dispensing device, product selection means 5 equipped with selection switches corresponding to the products to be sold, respectively;
6 is a change dispensing means, and 7 is a sales control means. Reference numeral 8 denotes mode switching means for switching the vending machine between a sales operation mode and a price setting mode, and the sales control means 7 operates in the sales operation mode. Further, 9 is a price input means for inputting a selling price to be set at the time of price setting, 1o is a price setting control means that operates in the price setting mode, and 11 is a product for which the selling price of the price input means 9 is set in the price setting mode. The detection means detects the column corresponding to the column, reads the sales price from the entire memory 2 of the price input means 9, and displays the set amount i in decimal notation on the corresponding sales amount display device 12.

In the sales operation mode, the sales control means 7 compares the input amount of the amount calculation device 1 with the sales price for each product set in the memory 2, and selects products that can be sold according to the presence or absence of change and products. After the determination, the salable products are displayed on the salable display means 3.

When the selection switch of the selection means 5 is operated, the sales control means 7 operates the sales drive means 4 when the selected product is a sellable product, drives the product dispensing device related to the selected product, and sells the product. do. In addition, the sales control means 7
reads the selling price of the selected product from the memory 2 and inputs it into the amount calculation device 1 to calculate the amount of change, and when change is required, the change dispensing device 6 is activated according to the amount calculated by the amount calculation device 1. make it work.

On the other hand, in the price setting mode, when a selling price to be set is introduced from the price input means 9 and a product is specified by operating the selection switch of the product selection means 5, the price setting means 1o The sales price storage area of memory 2 is addressed and the set sales price is written. At this time, the detection means 11 reads out the price written in each sales price storage area of the memory 2 by the price input means 9, and displays the sales amount in decimal notation on the corresponding sales amount display means 12. Therefore, it is possible to confirm the products for which the price of the price input means 9 is set as the selling price. The price input means 9 is constituted by a conventionally known input device such as a number key or a setting switch using a double code. Also,
By placing the sales amount display device 12 near the displayed products of the vending machine or near the selection switch, the sales price corresponding to the product can be easily understood.

FIG. 2 shows an embodiment in which the price setting according to the present invention is achieved by the microcomputer 13, and the boat P
1a""In is connected to each of the indicators L1a to L1n of the sales availability display means 3 corresponding to each product, and connected to each of the indicators L1 to Ln through all two ports P and the driver 14. The ports P3a to P3n are connected to the respective selection switches 81 to Sn of the product selection means 5, and the port P4 is a self-resetting changeover switch 1 that specifies the price setting mode.
5 is connected. In addition, each display L2 of the sales amount display means 12 corresponds to the ports P5a to 5n for each product.
a to L, and the port P6 is connected to each of the displays L2a to L2n through the driver 16. The mode switching means sets the mode to the price setting mode by operating the changeover switch 15 and starts timer operation, and is switched when the timer operation ends or the changeover switch 15 is operated again.

Also, the timer operation is performed by selecting the selection switch S1 within the timer period. S2. , , . . . , the operation status of Sn is updated by specifying the selling price on the price input means 9, and the selection switch S1 . S2. . . . If Sn or the price input means 9 is not operated, the mode is switched to the sales operation mode. The memory 2 includes a sales price storage area M1 for each product. M2. ...Mn and each selection switch S1. S2. . . . Selection switch flag registers R1, R2, . . . Rn indicating operation of sn, price setting flag register R0, and sales price register R
g and a timer counter TC are assigned.

3 and 4 are flowcharts illustrating the program of the microcomputer 13, and the input detection flow in FIG. 4 is periodically processed by a timer interrupt.

Now, when it is detected in step n3 of the input detection flow that the changeover switch 15 has been operated, the price setting flag FP in register R0 is checked in step n4, and if the price setting flag is not set, register R is set in step n6.
This flag FPI is set to 0 and a timer constant is set in the timer counter TC. Pricing control flow〇N. In the step, we check the pricing flag FP,
In this case, the flag FP is set at step n5 of the input detection flow.

In the next step n2, a timer constant is set in the timer counter TC to update the timer operation.

Furthermore, when the selling price information from the price input means 9 is detected at step n7 of the input detection flow by the timer interrupt, n
In step 8, this sales price information is set in the sales price register R8 of the memory 2, and in step n9, a timer constant is set in the timer counter TC to update the timer operation.

Assuming that the selection switch S2 is now operated and the selection switch flag SF2 is set in the register R2 in the input detection flow, in step N2 of the price setting control flow, the selling price of the memory 2 corresponding to the product of the selection switch S2 is set. In the storage area, the sales price stored in register R3 is written. Then, in step N3, the selection switch flag Fs2 of register R2 is reset, in step N4, the sales price stored in register R8 is stored in the corresponding storage area of memory 2, and in step N5, the selection switch flag Fs2 of register R2 is reset. Display paths L2a-L2n are operated and displayed. And on the N6 stenope, the timer counter T
The timer is subtracted by subtracting C, and the end of the timer operation is confirmed by the contents of the timer counter TC in step N7, and if it is not completed, the process returns to step N0. Also, within the timer operation period, the selection switch S1. S2.・・・・・・
- When Sn or the price input means 9 is operated, the timer operation is updated in the input detection flow and the price setting mode is extended.

When setting the sales prices stored in register R8 for multiple product types, press the corresponding selection switch S1. S
2. ......When you operate Sn, n of the input detection flow will be displayed each time. The selection switch flags FS, .
・Set the sales price to Mn, reset the selection switch flag in step N3, and set the sales price stored in register R8 in steps 2, N4, and steps to the corresponding storage area of memory 2, and step N5. The corresponding displays L2a to L2n of the sales amount display means 12 are activated and displayed.

When a new selling price is input in this way, register H
This selling price stored in the corresponding selling price storage area M1 of memory 2 is stored by operating the selection switch.
・It can be written to Mn and also displayed for confirmation.

Then, at step N7, the contents of timer counter TC are changed to "
When it detects that the timer has reached 0'', it is assumed that the timer operation has ended, and the process goes to step N8, where the price setting flag FP in register R0 is reset, and the N7''? ? The selling price of L/Jister R is cleared and the price setting control flow is ended.

Furthermore, if the changeover switch 16 is operated again within the timer operation period, the operation of the changeover switch 16 is detected at step n3 of the input detection flow by timer interrupt, but in this case, the price setting flag FP is set in register R8. Therefore, register R8 is reset and cleared at step n6. Then, when returning to the price setting control flow, the price setting flag FP is reset to N. Exit from the step and end the pricing control flow.

In the embodiment, the sales price of the corresponding product was stored by the product switch, but the price can be set by inputting the sales price at the same time as the corresponding selection switch or the column number containing the product using the price input means. Good too.

Effects of the Invention According to the present invention, the sales price set in the memory is displayed on the sales amount display means, so the set amount can be visually confirmed, and troubles with users may occur due to incorrect settings. There's nothing to do. This prevents the work of replacing a card with the entire sales amount written near the displayed product or selection button and forgetting to change it, which improves work efficiency and eliminates troubles with users.
