Next, the bargain sale period table 32 is searched using the bargain sale period code as a search key, and bargain sale start date data and bargain sale end date data corresponding to the bargain sale period code are read out. Then, it determines whether or not the purchase date data extracted from the receipt barcode 64 read by the barcode scanner 5 is within the special sale period from the special sale start date to the special sale end date (sale period determination means).

If it is within the special sale period, the above-mentioned unit price is used as the return price. If it is outside the special sale period, the above-mentioned normal unit price is used as the return price.
The drawer 6 is displayed on both screens 3a and 3b of the display 3 and a drive signal is output to the drawer opening device 6a to open the drawer 6. Further, the returned goods number = 1 and the returned goods amount are added to the returned goods point area and the returned goods amount area corresponding to the input goods code of the goods data file 31 (return goods registration processing means), and this processing ends.

As described above, in the POS terminal according to the present embodiment, when the customer offers a return, the cashier first operates the return key 2e to select the return registration mode, and then the receipt when the returned product is purchased. The receipt barcode 64 printed on the barcode 60 is read by the barcode scanner 5.
Read operation with.

Then, first, the receipt barcode 6
The number of days elapsed until today from the purchase date data of No. 4 is automatically obtained, and it is determined whether or not the elapsed days are within a preset return expiration date. Then, if the returned goods are within the expiration date, it is determined from the store number data of the receipt barcode 64 whether the receipt 60 is a receipt issued by the own store. If the receipt is issued at your own store, the display 3
Will display a message stating that your return has been accepted.
The cashier performs return registration.

That is, the cashier reads the barcode 62 corresponding to the product code of the returned product printed on the receipt 60 and the barcode printed or affixed to the returned product with the barcode scanner 5. If no barcode is printed or affixed to the returned product, the product code is entered using the numeric key 2a and the PLU key 2b of the keyboard 2.

When the product code (bar code) is input twice and the coincidence is confirmed, the product name, the normal unit price, the special unit price, and the special sale period code corresponding to the input product code are entered from the product data file 31. Data is read. The bargain start date data and bargain end date data corresponding to the bargain period code are read from the bargain period table 32.

Then, it is determined whether or not the purchase date detected from the receipt barcode 64 read by the barcode scanner 5 is within the bargain period from the bargain sale start date to the bargain sale end date. If it is within the bargain sale period, the bargain sale price is set as the return price. If it is outside the bargain sale period, the normal unit price is set as the return price and the return registration process is performed.

Therefore, when the customer offers to return the product, the cashier determines whether the returned product has passed the expiration date of the returned product, whether the returned product is the product purchased at the time, and whether the returned product has been returned. Since there is no awareness of whether or not a product has been sold during the special sale period, the burden on the cashier can be greatly reduced.

If the returned product is sold during the special sale period, the return is automatically registered at the special unit price of the corresponding product, and if the returned product is sold outside the special sale period, the return registration is automatically performed at the normal unit price of the corresponding product. Therefore, the sales data of the corresponding product always matches the actual sales. Therefore, even if a product that has been sold as a bargain sale is returned, an effect is achieved in that accurate sales management can be realized without burdening the cashier.

In the above-described embodiment, the bar code on the receipt corresponding to the returned product is read, and then the bar code printed or affixed to the returned product itself is read. However, the order in which the bar codes are read is as follows. The reverse is also acceptable.

In the above-described embodiment, the receipt information such as the product code of the purchased product and the date of purchase is printed out with a barcode, and the returned information is read out by the barcode scanner 5 when the product is returned. It may be printed out and read by an OCR (optical character reader) when returning the product. In addition, it goes without saying that various modifications can be made without departing from the spirit of the present invention, such as applying the present invention to a single electronic cash register.

[0053]

As described in detail above, according to the first aspect of the present invention, it is not necessary to check whether or not the expiration date of the returned product has passed when a request for return is received from a customer. In addition to reducing the cashier's burden at the time of return, in the case of returns of products sold during the special sale period, return registration processing is performed at the special unit price, otherwise return registration processing is performed at the normal unit price, so there is a return Can also provide a product sales data processing device capable of realizing accurate sales management. Also,
According to the invention of claim 2 of the present application, it is not necessary to check whether or not a product sold at its own store is returned when a request for return is received from a customer, so that the burden on the cashier at the time of return can be reduced. In the case of returns of products sold during the bargain sale period, returns are registered at the bargain sale price, and at other times, returns are registered at the normal unit price, so product sales that can achieve accurate sales management even if there is a return A data processing device can be provided.
