As shown in FIG. 4, the RAM 14 has the following information:
Product information setting area 31 for product code, product name, and unit price
A product file 31 is provided, which is comprised of cumulative areas 31d, 31e for the number of items sold and sales amount, and cumulative areas 31f, 31g for the number of returned items and amount returned. In this product file 31, the product code, product name, and unit price of each product sold at the store are preset in each information setting area 31a to 31c by a setting process. In addition, the cumulative area 31d for sales points and sales amount
, 31e, the number of sales items and sales amount of each product registered for sale are accumulated by product code. Similarly, the cumulative areas 31f and 3 for the number of returned items and returned amount
1g, the number of returned items and the returned amount for each product registered as a returned item are accumulated by product code. In addition,
The contents of each cumulative area 31d to 31g are set to 0 each time a settlement report for the product file 321 is issued due to settlement operations.
“It will be cleared.

The CPU 11 is program-controlled to execute the return key process shown in FIG. 5 in response to a key input to the return key 2f of the keyboard 2. That is, with the mode switch 3 selecting the "registration" mode, the return key 2 is pressed via the keyboard controller 18.
When the key signal of f is taken in, the state of the return key flag F is checked. If the flag is set to "1", it is reset to "0" and becomes the sales registration mode, and "0" is set.
”, set it to “1” to set the return registration mode and end this key processing. (Mode switching means) Note that if the return key 2f is input in a mode other than the “registration” mode , the key input is treated as an error.

Further, the CPU 11 is program-controlled to execute the scanning process shown in FIG. 6 in response to a barcode reading operation by the barcode scanner 8. That is, when the scanner interface 2 is set to the "registration" mode with the mode switch 3,
2, the return key flag F is checked. If the same flag F is reset to "0", the barcode of the product was read while the sales registration mode was selected, so first, the product code of the barcode is used as the key to sell the product. The file 31 is searched to read out the product name and unit price corresponding to the product code. (Information reading means)

Next, the number of sales items and sales amount cumulative area 31 corresponding to the product code in the product file 31 is displayed.
d and 31e are cumulatively processed with 1 as the number of sold items and the unit price as the sales amount. (Sales registration processing means)

00
17] Also, convert the product code into a barcode. Then, the printer 20 prints the product name, unit price, number of items sold, and sales amount as well as the barcode obtained by this conversion on a receipt, and this process ends. (Receipt printing control means)

On the other hand, if the return key flag F is reset to "1", the barcode of the product was read while the return registration mode was selected;
After all, the barcode is converted into a numerical code, that is, a product code (barcode conversion means), and the corresponding product name and unit price are read out from the product file 31 using the obtained product code as a key (information reading means), and the above-mentioned product file is read. 31
1 is accumulated as the number of returned items and the unit price is accumulated as the returned amount in the returned item number and returned amount amount accumulation areas 31f and 31g corresponding to the product code. (Returned goods registration processing means) If a barcode reading operation is performed in a mode other than the "registration" mode, the reading operation is treated as an error.

Furthermore, the CPU 11 is program-controlled to execute code key processing shown in FIG. 7 in response to key inputs from the code key 2c of the keyboard 2. That is, when the key signal of the code key 2c is input via the keyboard controller 18 while the "registration" mode is selected by the mode switch 3, the numerical data is input by the numeric key 2a immediately before inputting the code key 2c. Determine whether a number has been input. If the numeric data has been input, it is recognized as a product code, and the same process as the barcode (product code) scanning process shown in FIG. 6 is executed.

[0020] In addition, in other than the "registration" mode, the code key 2
If c is keyed in, or if the code key 2c is keyed in without a code being entered, the keystroke is treated as an error.

In this embodiment having such a configuration, by selecting the "registration" mode with the mode switch 3, it is possible to register the products purchased by the customer for sale. In this state, read the barcode attached to the product using the barcode scanner 8, or use the number key 2 on the keyboard.
When the product code of the product is entered using the keys 2c and 2c, the sales data of the product is accumulated by product code in the sales number and sales amount accumulation areas 31d and 31e of the product file 4. At this time, the receipt shows the product name (chocolate), unit price (unit 200), number of items sold (1x), and sales amount (¥200) of the product registered for sale, as well as the product code of the product, as shown in Figure 8. A barcode 81 is printed out.

[0022] On the other hand, if the customer requests to return the product, the customer is requested to show the receipt of the purchase of the returned product. If the returned product was indeed purchased at a store, the product code barcode 81 is printed on the receipt along with the sales data of the returned product, so enter the return key 2f to enter return registration mode. After specifying, the barcode scanner 8 reads the barcode 81 of the returned product on the receipt. Then,
Return data of the corresponding product is accumulated in the number of returned items and returned amount amount accumulation areas 31f and 31g of the product file 4 for each product code.

[0023] According to this embodiment, the product code of the product purchased by one customer is converted into a bar code and printed on the receipt together with the sales data of the product.
When registering a return, you can simply read the barcode of the returned product printed on the receipt with the barcode scanner 8, which simplifies the process of entering the product code when registering a return. No more mistakes in entering product codes.

[0024] Furthermore, even if a product does not have a barcode attached to it, the barcode of the product will be printed on the receipt, so when registering a return, regardless of whether the product has a barcode attached to it or not. There is also the advantage that scanning operations using the barcode scanner 8 can be used.

In the above embodiment, the bar code of the registered product is printed on the receipt each time the product is registered for sale, but a memory is provided to store the product code of the registered product for one transaction, and By inputting the key (deposit/total key 2e), the barcodes of all products purchased by one customer may be printed on the receipt.

[0026] Furthermore, if a barcode is attached to the returned product, the return registration can be processed by reading the barcode, so there is no means for determining whether the product registered for sale is a product with a barcode or not. may be provided, and the barcode of the product code may be printed on the receipt only in the case of sales registration of a product without a barcode. This way you can save on receipts.

In addition, various methods may be used without departing from the gist of the present invention, such as using a stationary type barcode scanner 8 or switching between the sales registration mode and return registration mode using a method other than the return key 2f. Of course, modifications are possible.

[0028]

[Effects of the Invention] As detailed above, according to the present invention, the product code of each product registered for sale is converted into a barcode and printed on the receipt, and the barcode printed on the receipt is read.
