is a means of controlling sales. And (9) is a mode switching means for switching the vending machine between a sales operation mode and a price setting mode, and the sales control means (6) operates in the sales operation mode.

In addition, (8) is a price input means for inputting the selling price to be set at the time of price setting, a[ is a price setting control means that operates in the price setting mode, and aυ is the selling price of the price input means (8) in the price setting mode. The detection means detects the set product, and the selling price of the price input means (8) and the memory (2
) is detected by comparing the selling prices set in ).

In the sales operation mode, the sales control means (6) compares the input amount of the amount calculation device (1) with the sales price for each product set in the memory (2), and also calculates the amount of money input according to the presence or absence of change and products. The salable products are determined and the salable products are displayed on the salable display means (3).

Then, when the selection switch of the selection means (5) is operated,
The sales control means (6) 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.

On the other hand, the sales control means (6) reads the sales price of the selected product from the memo (January 2), inputs it into the amount calculation device (1), calculates the amount of change, and when change is required, the amount calculation device ( 1
) The change dispensing device (7) is operated according to the operation class.

On the other hand, in the price setting mode, when the selling price to be set is introduced from the price input means (8) and a product is specified by operating the selection switch of the product selection means (5), the price setting control means is the memory related to the specified part type (
2) Address the sales price storage area and write the set sales price. Then, in the price setting mode, the °C detection means αυ sequentially compares the price of the price input means (8) with the price written in each sales price storage area of the memory (2), and compares the price of the price input means (8J) in sequence. Therefore, the detection means (8) is the price input means (8).
The device detects products for which a price of do.

Then, when the sales availability indicator lights up, the price input means (8)
You can check the products for which the price of is set as the selling price. In this way, when a product whose price is to be softened is specified by operating the selection switch and the selling price to be set is input into the price input means (8), the memory corresponding to the specified product (
The set price is written in the selling price storage area of 2), and the sellable indicator of the designated product lights up. Price input means (8
) is constituted by a conventionally well-known input device such as a number key or a setting switch using a binary code, but it can also be input by inserting money equivalent to the selling price to be set. In this case, the function of the amount calculation device (1) to calculate and output the input amount also serves as the price input means (8), and the price setting control means Ql is in the price setting mode when the amount calculation device (1) K
The input amount information shown in is stored in memory as the set selling price (
Set to 21.
