Here, the CPU 21 and the printer 4
Is a receipt that issues a receipt printed with merchandise sales data and total data registered by the sales registration processing means in response to the key input of the closing key 2d, and store number data as preset store identification data. Construct issuing means.

FIG. 4 shows an example of issuing a receipt 40 in this embodiment. This receipt 40 has a sales amount of 10
Product A for 0 yen and Product B for 200 yen each for 1
It is a receipt issued to a customer who has purchased points by point, and a receipt barcode 44 including a purchase date 41, a store number 42, and a total purchase price 43 is printed. In addition,
In the receipt 40, reference numeral 45 denotes an area on which a store name, a logo mark, and the like are printed, 46 denotes the date and time of purchase,
7 is product sales data, 48 is total data (deposit amount,
(Including change), 49 is a responsible person number, and 50 is a terminal number.

The CPU 11 is configured to execute the processing shown in FIG. 6 when the return key 2e of the keyboard 2 is input while the "registration" mode is selected by the mode switch 7. ing.

That is, when it is confirmed that the "registration" mode is selected in ST11 and that the registering flag is reset in the flag memory 34 in ST12, sales registration of the product purchased by one customer is performed. Since the return registration mode has been declared in a state in which it has not been performed, the money totalizer 32 is cleared to "0" in ST13.

Next, at ST14, the timer counter 35
Starts the counting operation. In step ST15, the process waits for input of barcode data read by the hand scanner 5 via the scanner interface 20.

If the bar code data is input before the count time of the timer counter 35 elapses a preset time (for example, 15 seconds), ST1 is reached.
At 6, it is determined whether or not the barcode data is the data of the receipt barcode 44 printed on the receipt 40.

In the case of the data of the receipt bar code 44, the receipt bar code 4 is read in ST17.
The number of days elapsed from the purchase date data 41 of 4 to the current date measured by the clock circuit 14 is determined, and whether the elapsed days are within a preset return expiration date (for example, 7 days) or not is determined. to decide.

If the return period is not reached, ST
At 18, it is determined from the store number data 42 of the receipt bar code 44 whether or not the receipt is issued at the own store. And
In the case of a receipt issued at the store, a message indicating permission for return registration is displayed on the display 3 in ST19.

Thereafter, in ST20, a single item code of the product is input by the code input means, and a numeral key 2 is input.
When the number is set in a, the return registration of the corresponding product is instructed. In ST21, the set amount is registered in the transaction-specific memory 31 as the return price data of the corresponding product for each returned product classification. In addition, the return amount data is stored in the total amount
Is added to.

On the other hand, if the closing key 2d is keyed in ST22, the end of the returned goods registration is instructed.
In ST23, the contents (refund amount) of the amount totalizer 32 are displayed on the display 3. In addition, the drawer 6 is opened, and this processing ends.

If the time counted by the timer counter 35 exceeds the set time before the barcode data is input in ST15 and a timeout occurs, a key input error of the return key 2e is determined. If the barcode data input in ST16 is data other than the receipt barcode 44, a barcode reading error is determined.

In step ST17, the receipt barcode 4
If the number of days elapsed from the purchase date data 41 of No. 4 has expired, and if it is determined in ST18 that the receipt is not a receipt issued at its own store from the store number data 42 of the barcode for receipt 44, it is displayed in ST24. A message indicating that return registration is not possible is displayed on the device 3 and the process is terminated.

Here, the hand scanner 5 constitutes data reading means for reading the shop identification data printed on the receipt 40, that is, the shop number. In addition, the CP
U11 determines permission / non-permission of return registration based on the store identification data when the store reading data is read by the data reading means together with the key input of the return key 2e in the processing of ST11 to ST18 of the return key processing. Return registration processing means for registering return data of a corresponding product when a code of a returned product is input by the code input means in a state where return registration is permitted in the processing of ST19 to ST21. Is configured.

In a supermarket or the like using the POS terminal 1 of the present embodiment configured as described above, store number data for specifying the store is set in the store number memory 33 in advance. In this state, the cashier sells and registers the product purchased by the customer, and operates the closing key 2d to declare the closing of registration of the customer. The receipt 40 on which is printed is issued. The receipt barcode 44 is created from the purchase date data 41, the store number data 42, and the total amount data 43.

On the other hand, when the customer wants to return the previously purchased merchandise, the cashier keeps the returned merchandise from the customer and the receipt 40 when the returned merchandise was purchased. And
After inputting the return key 2e and declaring the return registration mode, the hand scanner 5 reads the receipt barcode 44 printed on the receipt 40.

Then, first, the receipt bar code 4
The number of days elapsed until today is automatically obtained from the purchase date data 41 of No. 4 and it is determined whether or not the number of days elapsed is within the preset return expiration date. If the returned goods are within the expiration date, the store number data 42 of the receipt barcode 44 is stored.
It is determined whether or not the receipt 40 is a receipt issued at the own store. If the receipt is issued at the store, a message indicating permission for return registration is displayed on the display 3.

On the other hand, when the elapsed days have passed the return expiration date or when the store number data does not match the store number set in the store number memory 33, it is determined that the store is not the receipt of the store. In this case, a message indicating that the return registration is not permitted is displayed on the display 3.

Therefore, only when a message indicating permission for return registration is displayed on the display 3, the cashier reads the barcode of the returned product with the hand scanner 5 and performs return registration as in the conventional case.

As described above, in the present embodiment, the data specifying the store is printed on the receipt 40 issued to the customer, and at the time of return registration, the store specifying data printed on the corresponding receipt 40 is read. It is determined whether or not the receipt is issued at the own shop based on the shop identification data and the permission / rejection of the return is automatically determined. Therefore, only the products purchased at the own store can be registered for return, and the return of the products purchased at other stores will not be accepted, so the value obtained by subtracting the returned number from the sold number of products is the actual value of the store. It matches the sales quantity, and the product management is assured.

In the above embodiment, the store number is specified as data for specifying the store, and the store number is converted into a bar code to print the receipt. However, the present invention is not limited to this. May be used as store specifying data, which may be read by an OCR (optical character reading device). In addition, it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0045]

As described above in detail, according to the present invention, it is determined whether or not a returned product is a product purchased at the own store, and only a product purchased at the own store is allowed to be returned. Therefore, it is possible to provide a product sales data processing device capable of realizing accurate product management.
