Abstract

PURPOSE:To simplify commodity registering operation by registering commodity sale data based on the sale information of one customer stored by an information processing means when commodity registration is right. CONSTITUTION:All commodities bought by the customer are weighed in a lump by a weighing scale 5, and simultaneously, the card information of cards 6 corresponding respectively to all the commodities bought by the customer is read successively by a card reader. Thus, the sale information of the corresponding card information is stored by a card information processing means 1, and simultaneously, weight information is totaled. Then, when the weight total information and weighed value at the weighing scale 5 agree nearly with each other, the commodity registration is judged to be right, and the registering processing of the commodity sale data is executed based on the basis of the stored sale information. Thus, the commodity registering operation can be easily executed.

On the other hand, as shown in FIG. 7, in the RAM 44, the unit price of each product is set in accordance with the PLU code attached to each product handled in the store, and the number of sales items and sales amount of each product is stored in the PLU. A cashier-side PLU file R6 with a tally area for counting by code; a sales data buffer that temporarily stores the PLU codes, number of sales items, and total price of all purchased products of one customer registered in the checker terminal 1; R7 etc. are formed.

The CPU 21 of the checker terminal 1 is programmed to execute the process shown in FIG. That is, after a predetermined initial process is performed in response to the power being turned on, the message "Please place your basket" is displayed on the display 9. Next, it waits for weighing on the weight scale 5 as STI. When it is detected that weighing has been performed, the weight data corresponding to the load is taken from the weight scale 29 as count data via the A/D converter 29, converted to a weight value, and further The actual weight of the product group stored in the shopping cart 3 is calculated by subtracting the set weight value of the shopping cart 3. Then, the calculated actual weight is stored in the scale memory R2. Further, the actual weight and the message "Please insert card" are displayed on the display 9.

Further, the contents of the weight totalizer R3 and the amount totalizer R4 are each initialized to "0".

Next, the magnetic card 6 is inserted from the card insertion lower as Sr1.
is inserted. When it is determined that the magnetic card 6 is inserted, the card data read by the card reader 26 is imported via the card reader interface 27, the PLU code in the card data is searched for in the checker side PLU file R1, and the corresponding Call up the unit price corresponding to the PLU code. Then, the product weight in the card data is added to the weight totalizer R3, and the called unit price is added to the amount totalizer R4. Then, the total weight value and the total amount of money after addition are displayed on the display 9. It is also determined whether the PLU code has already been registered in the registration data buffer R5. If it is registered, "1" is added to the score area corresponding to the PLU code in the registered data buffer R5. On the other hand, if the PLU code is not registered, the PLU code is set in an empty area of the registration data buffer R5, and the number of sales items "1" is set in the number area. After that, Sr.
Return to 1. (Card information processing means) When Sr1 determines that the magnetic card 6 is not inserted, Sr
1, it is determined whether the card end key 8a of the keyboard 8 is pressed manually. If the key is not pressed manually, cancel key 8 of the same keyboard 8 is used as Sr4.
Determine whether or not b is key operated. If the key is not pressed, the process returns to Sr1.

Sr1 determines whether the magnetic card 6 is inserted, and Sr1 determines that the magnetic card 6 is not inserted.
When it is determined in step 1 whether the card end key 8a is pressed manually, Sr1 compares the actual weight in the scale memory R2 and the total weight value in the weight totalizer R3 to determine whether they match (validity). means of determining sex). In this case, if the deviation of the surface weight values is within a preset tolerance range, it is considered that they match. If the surface weight values match, it can be determined that the product weighed on the weight scale 5 has been properly registered using the magnetic card 6.
A sales data message is edited from each PLU code and the number of sales items in the registered data buffer R5 and the total amount in the amount totalizer R4, and is sent to the cashier terminal 2 via the communication interface 28. Then, it waits for a response from the cashier terminal 2. Here, if there is an abnormal response from the cashier terminal 1, the message "Please wait a moment" is displayed on the display 9 and the message is sent again. If there is a normal response to this, the message "Please make payment" is displayed on the display 9. Next, the operator waits for the shopping cart 3 to be removed from the weight scale 5 as Sr6. When it is detected that the shopping cart 3 has been removed, the registered data buffer R5 and scale memory R2 are cleared.
Then, the message "Please place the basket" is displayed again on the display 9, and the process returns to ST1.

In addition, if it is determined in ST5 that the actual weight in the scale memory R2 and the total weight value in the weight totalizer R3 do not match, the magnetic card 6 of the product weighed on the weight scale 5 is Since it can be determined that the registration was improperly performed, a predetermined error message is displayed on the display 9, and an error sound is made to sound from the buzzer 31 for a certain period of time.

Thereafter, the process advances to ST6 and waits for shopping cart 3 to be removed from weight scale 5. When it is detected that the shopping cart 3 has been removed, the registered data buffer R5 and scale memory R2 are cleared, and the message "Please place the shopping cart" is redisplayed on the display 9, and S
Return to TI.

Also, in ST2, it is determined that the magnetic cart 6 is not inserted, and S
At T3, it is determined that there is no key power for the card end key 88,
If it is determined in ST4 that the cancel key 8b is pressed manually, the process immediately proceeds to ST6 and waits for the shopping cart 3 to be removed from the weight scale 5. When it is detected that the shopping cart 3 has been removed, the registered data buffer R5 and scale memory R2 are cleared, and the message "Please place the cart" is redisplayed on the display 9, and the process returns to STI.

On the other hand, the CPU 41 of the cashier terminal 2 is programmed to execute the process shown in FIG. That is, after performing predetermined initial processing in response to power-on, it is determined whether or not a sales data message has been received from the checker terminal 1 via the communication interface 47 as 5TII. Then, if it is being received, the flag F allocated in advance in the RAM 44 is checked. Here, if the flag F has been reset to "O", it is set to "1" and a normal response is returned to the checker terminal 1 via the communication interface 47. Also, store the received data in the sales data buffer R7,
Return to 5TII.

On the other hand, if the flag F is set to "1", the previous payment has not yet been completed, so an abnormal response is returned to the checker terminal 1 via the communication interface 47, and an error response is sent to the 5TII. return.

If the sales data message is not received at 5T11, it is determined at 5T12 whether or not there is any key input from the keyboard 10. And judging from the lack of key personnel, 5TII
Return to

When it is determined in step 5T12 that there is a key input from the keyboard 10, the type of input key is checked and the corresponding key process is executed. Here, if the input key or the current key is 4, the flag F is checked.

If the same flag F is set to "1", a sales data message has been received, so registration processing is performed based on the data in the sales data buffer R7 (registration processing means). That is, first, the sales data buffer R7 to 1
1 PLU code and the corresponding number of sales items are read out.

Next, from the cashier m PLU files R6,
Calculate the price by calling the unit price corresponding to the code. Then, the number of sales items and the price are added to the total area corresponding to the PLU code of the cashier m PLU files R6. Thereafter, similar processing is sequentially performed for all PLU codes in the sales data buffer R7, and when completed, the total amount in the buffer R7 is displayed on the display 1. In addition, the printer 48 is driven to sequentially print out the PLU code, the number of sales items, and the price on the receipt and journal,
Finally match =! The amount is printed out and a receipt is issued from a receipt issuing port 13. At this time, the drawer 12 is opened. Thereafter, the sales data buffer R7 is cleared, the flag F is reset to "0", and the process returns to 5T11.

In this embodiment with such a configuration, the customer puts all the purchased products into the shopping cart 3 and returns to the checker terminal 1.
Go to the installation location. At this time, all magnetic cards 6 attached to the purchased products are removed. Then, if the message "Please place your cart" is displayed on the display 9 at the checker terminal 1, the shopping cart 3 is placed on the weight scale 5. Then, the total weight of all the purchased items in the shopping cart 3 is calculated and stored in the scale memory R2, and the total weight and the message ``Please insert your card'' are displayed on the display 9. Then, the customer sequentially inserts the magnetic cards 6 removed from all the purchased products into the card insertion lower. Then, the card information of each inserted card 6 is sequentially read by the card reader 26, and the product weight of each card information is added up by the weight totalizer R3. Further, the corresponding unit price is read out from the PLU file R1 according to the PLU code of each card information, and added up by the amount totalizer R4. Further, the PLU code and the number of sales items are registered together in the registration data buffer R5. In this way, when the customer has finished inserting the magnetic cards 6 for all purchased products, he or she presses the card end key 8a on the keyboard 8. Then,
The total weight of all purchased products stored in scale memory R2 is compared with the total weight value stored in weight totalizer R3. If the two weight values almost match, it means that all the card data on the magnetic cards 6 corresponding to all the products weighed on the weight scale 5 have been read, so the product registration has been done legitimately. Then, a sales data message is edited from the sales information in the registered data buffer R5 and the total amount information in the amount totalizer R4, and is sent to the cashier terminal 2. When the message is successfully sent to the cashier terminal 2, the display 9
Since the message "Please make payment" is displayed, the customer takes the shopping cart 3 and moves to the location where the cashier terminal 2 is installed.

On the other hand, in the cashier terminal 2 which has received the sales pig message from the checker terminal 1, the sales information and total amount information in the message are stored in the sales data buffer R.
7 is temporarily stored. In this state, when 4 keys are pressed on the total key of the keyboard 10, the registration process of sales products is performed based on the sales information in the buffer R7. Further, the total amount is displayed on the display 11, and a receipt is issued from the receipt issuing port 13. Therefore, when a customer who has self-registered at the checker terminal 1 offers to pay, the clerk operating the cashier terminal 2 manually inputs 4 on the cashier key. Next, the customer receives a payment corresponding to the sum = 1 amount displayed on the display 11,
If necessary, change is collected from the drawer 12 and handed to the customer along with the receipt.

In this way, in this embodiment, it is possible to register the purchased product for sale by simply inserting the magnetic card 6 corresponding to the purchased product from the card insertion lower of the checker terminal 1. This eliminates the need for reading operations. Generally, anyone can easily read card information recorded on a card using a card reader. Therefore, the product registration operation becomes simple and the burden on customers is reduced even if self-registration is adopted. Furthermore, since the registration process does not take much time or effort, the flow of customers will not be slowed down even during busy times. As a result, self-registration can be carried out effectively,
Excellent effects such as labor saving and manpower saving can be achieved.

In the above embodiment, the checker terminal 1 and the cashier terminal 2 are in one-to-one correspondence, but on the cashier terminal 2 side, it is possible to distinguish which checker terminal 1 the customer registered the product at. By providing a function, it is also possible to provide n to 1 (n≧2) correspondence.

Further, the card provided for each product is not limited to the magnetic card 6, but may be an IC card, a racer card, or the like. It goes without saying that the present invention can also be applied to cases in which product registration is performed by a store clerk rather than self-registration.

[Effects of the Invention] As detailed above, according to the present invention, it is possible to register a product for sale by simply having a card reader read the card information recorded on the card, which simplifies the product registration operation. It is possible to provide a product sales data processing device that can reduce the burden required for registration and reduce the time required.
