Abstract

PURPOSE:To improve sale efficiency by reducing the number of change by subtracting a change amount paied from a change paying device from a balance by processor. CONSTITUTION:The processor 1 stores a calculated value into a register B by subtracting an amount when the maximum number of products with the highest sale price are purchased from the balance stored in a register A. The processor 1 issues an instruction to pay the amount stored in the register B as the change to a change paying device 2. Thereby, the device 2 pays the amount unrequired for the next sale as the change in advance. And the amount stored in the register B is subtracted from the amount stored in the register A and a result is stored in the register A. Therefore, the amount after the change a already paid as the amount unrequired for the next sale is subtracted from the amount after sale is stored in the register A.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention provides a vending machine that is capable of continuously selling products as long as the remaining amount after sales is still greater than the selling price of the product. Regarding.

(b) Conventional technology As disclosed in, for example, Japanese Utility Model Publication No. 12696/1983, the automatic vending machine generally dispenses change after all the products have been sold in a continuous manner. be.

(c) Problems to be solved by the invention However, in conventional vending machines that dispense change at the end of a continuous sale, a series of sales operations and change dispensing operations are performed serially, which takes up the entire sales time. The disadvantage is that it becomes long.

Therefore, the present invention allows coins that are not needed in the next sale to be paid out in advance for each sale in a continuous sale.
To provide a vending machine capable of shortening the entire sales time by reducing the number of change dispensed when all consecutive sales are completed.

(d) Means for solving the problem In order to solve the above problem, the vending machine according to the present invention calculates the remaining amount by subtracting the selling price from the calculated amount each time a product is sold in succession. A computing device, and when the remaining amount is calculated by the computing device, if this remaining amount does not match the amount that is an integral multiple of the selling price of the most expensive item, the amount that is less than the remaining amount and is the closest integral multiple thereof. and a change dispensing device that determines the difference between the remaining amount calculated by the -C calculation and the amount detected by the detecting device and dispenses it as change, and the arithmetic device includes The configuration is such that the amount of change to be paid out is subtracted from the remaining amount.

(f) As long as the amount calculated by the action calculation device is greater than or equal to the selling price of the product, the product can be sold continuously, and when sales occur, the calculation device subtracts the selling price of the product from the calculated amount to calculate the remaining amount. do. Once the remaining amount has been calculated, the detection device determines whether this remaining amount is an integer multiple of the selling price of the most expensive item. If it is a non-integer multiple, this remaining amount is determined from among the integer multiples of the selling price. Find the amount that is less than and closest to this. When the detection device detects the amount closest to the amount calculated by the arithmetic device, the change dispensing device pays out the difference between the two as change, and the arithmetic device subtracts the amount of change dispensed by the change dispensing device from the remaining amount. The continuation of continuous sales is then determined based on the amount after calculating the knee.

(f) Embodiment FIG. 1 shows a control device for a vending machine according to the present invention, in which (7), (8), (9), and (1, 0) are coin detection devices provided for each type of input coin, (4). ) is a price storage device that stores each selling price for each product type, (2) is a change dispensing device,
(5) is a product selection device. This product selection device (5)
includes selection switches (6) to (6) corresponding to the types of products sold by the vending machine, and when the customer operates the selection switches (6) to (6) corresponding to the product to be purchased, the product is selected. Outputs a selection signal indicating 1-.

And (3) is a sales device that responds to the input of a product sales signal and performs a sales operation for the product indicated by this signal.

(1) is a processing device, and coin detection device (7) (8) (9)
The function of the calculation device is to count the input money signal introduced from (10) to calculate the input amount, and also to calculate the remaining amount after selling the product, and the calculated remaining amount is stored in the price storage device (4). The detection device has a function that detects an amount that is less than and the closest integer multiple of the highest selling price when the amount does not match the amount that is an integer multiple of the highest sales price among the remaining prices, and It has a function of determining the difference between the amount and outputting a change payout command to the change payout device (2) so as to pay out the difference. And further processing equipment (
1) is a continuous sales judgment function that determines whether it is possible to continue selling the product based on the remaining amount after the sale or the remaining amount after subtracting the change amount from the remaining amount if change is paid out. have.

The operation will be explained by referring to flowchart -1 in FIG. First, in step S1, when money is inserted and a corresponding inserted money signal is generated from the corresponding coin detection device (7), (8), (9), or (10), in step S2, the processing device (1) detects the input money signal indicated by the inserted money signal. The amount of money is added and counted to calculate the input amount and stored in the internal register A. and 8
When the selection signal from the product selection bag holder (5) is detected in 3 steps, the processing device (1) determines whether the product indicated by this selection signal can be sold in the next 84 steps. In this case, the processing device (1) reads the selling price of the selected product from the price storage device (4) and compares it with the amount stored in register A to determine the possibility of sale. If it is possible to sell, the processing device (1
) outputs a product sales signal to the sales device (3) instructing the sale of the selected product. This drives the sales device (3) and starts selling the selected product.

In the next step 86, the processing device (1) subtracts the selling price of the product to be sold from the memory stored in the register A. Then, in step 87, the processing device (1) detects the maximum number of products with the highest selling price that can be purchased within the remaining amount stored in the register A. in this case,
The processing device (1) reads the maximum selling price from the price storage device (4>) and divides the remaining amount by this selling price to detect the maximum number of products n that can be purchased.The next step is S8.
At SDEPP, the amount when the maximum amount of products with the highest selling price has been purchased is subtracted from the remaining amount stored in register A.
The calculated value is stored in register B. In the next step 89, it is determined whether the value of register B is O or not, and if it is 0, S1
The process proceeds to Step 2, but if the value is other than 0, the process proceeds to Step S10. In step 810, the processing device <1) gives a change payout command to the change payout device 2) to pay out the amount stored in the register B as change. This prevents the change dispensing device (2) from dispensing unnecessary amounts as change in advance for the next sale. In the next step, the amount stored in register B is subtracted from the amount stored in register A, and the result is stored in register A. Therefore, in the register A, the amount after subtracting the amount of change already paid out as an unnecessary amount for the next sale from the remaining amount after the sale is stored.

Step S12 is the amount stored in register A.
Furthermore, it is determined whether it is possible to continue continuous sales. In this case, the processing device (1) compares the amount stored in the register A with each sales price stored in the price storage device (4), and if the amount in the register A is greater than or equal to the sales price, the processing device (1) sells the product continuously. Return to step 83 to continue.

However, if continuous sales are impossible, the processing device <1) outputs a change payout command to the change payout device (2) to pay out the amount in register A, and the change payout device (2) outputs a change payout command to pay out this amount. ) dispenses change and the vending machine ends the vending operation.

To explain the above operation using a specific example, the price storage device (
Assuming that the selling prices stored in 4) are 60 yen, 70 yen, and 80 yen, now 250 yen has been added and the sales price has increased to 70 yen due to continuous sales.
Consider the case of selling three yen products. At this time, for the first sale, 180 yen is first stored in register A as the remaining amount from the product sale. And if you are satisfied with this 180 yen, even if you purchase two products with a maximum selling price of 80 yen, you will definitely have 20 yen left over, so 20 yen will be returned.
Another 20 yen is subtracted from the amount stored in register A, resulting in 16
0 yen is stored. When the second sale is made, 90 yen is stored in register A, but with this amount, if a product with a maximum selling price of 80 yen is purchased, there will be 10 yen left over, so this 10 yen is returned. In register A, 10 yen is further subtracted and 80 yen is stored. When the third sale is made, the remaining 10 yen is paid out and the sale ends. Therefore, between each sales operation in a continuous sale, unnecessary amounts are paid out for the next sales operation, so the amount of change to be paid out after the sale is reduced by that amount, which shortens the change payout time and, in turn, increases the sales operation time. It saves time.

(G) Effects of the Invention According to the present invention, in order to pay out unnecessary remaining amount as change in advance for the next sale in each sales operation in a continuous sale, the number of change that is paid out after the end of the continuous sale. This reduces sales time and improves sales efficiency.
