The communication device 20 communicates with another device such as a server (not shown) via a communication network 200 such as a LAN (local area network) or the Internet.

Next, the operation of the product data processing device (POS terminal 2) in the present embodiment will be described.
3 and 4 are flowcharts of control processing by the POS terminal 2 (CPU 10) in the present embodiment. The CPU 10 executes the control process shown in FIGS. 3 and 4 according to the control program stored in the ROM 11 or the auxiliary storage unit 13. The content of the process described below is an example, and various processes capable of obtaining similar results can be appropriately used.

When the POS terminal 2 is started in response to the power switch (not shown) being turned on by an operator or the like, the CPU 10 starts execution of the control program and starts the control process shown in FIGS. 3 and 4.

The CPU 10 executes an initialization process for initializing each part constituting the product data processing device 100 (Act1). For example, the initialization process includes a process of clearing the tag list area 12a and the product list area set in the RAM 12. Further, the initialization includes a process of displaying a screen (operation screen) for accepting an input operation for the checkout process on the touch panel 22.

After the initialization is completed, the CPU 10 confirms whether or not the start of the checkout procedure is requested by a predetermined operation such as touching a scan button provided on the operation screen. When the start of the procedure is not requested (Act2, No), the CPU 10 waits for the start of the procedure to be requested.

The operator usually accommodates the goods to be purchased by the customer in the tag reading chamber of the reading device 1 prior to the operation requesting the start of the procedure. That is, the operator opens the opening / closing lid 1b of the reading device 1, accommodates the reading device 1 in the tag reading chamber through the opening, and then closes the opening / closing lid 1b. In this case, as shown in FIG. 1, the shopping carts 6 and 7 may be stored in the tag reading chamber with the products in the shopping carts 6 and 7, or only the products may be stored in the tag reading chamber. good. Generally, when the number of products to be purchased is large, the customer puts the products in the shopping cart 6 and brings them to the accounting counter 3. In this case, the product may be stored in the tag reading room with the product in the shopping cart 6. On the other hand, if the number of products to be purchased is small and the customer can hold the products by hand, the customer may bring only the products to the accounting counter 3. In such a case, the operator may put the product in a separately prepared shopping cart and store it in the tag reading room, or may save the trouble of preparing the shopping cart and store only the product in the tag reading room.

When the CPU 10 detects that a predetermined operation for requesting the start of the procedure has been performed (Act2, Yes), the CPU 10 activates the reading operation by the tag reader 26 (Act3). The tag reader 26 outputs radio waves to the tag reading chamber space to read tag data for the RFID tag existing in the tag reading chamber space. Here, when the tag data is read from the RFID tag (Act4, Yes), the tag reader 26 notifies the CPU 10. When a plurality of RFID tags (commodities) are present in the tag reading chamber, the tag reader 26 reads tag data from the RFID tags one by one by, for example, a well-known procedure, and sequentially notifies the CPU 10.

In the CPU 10, the tag data read by the tag reader 26 (hereinafter referred to as received tag data) is an RFID tag (hereinafter referred to as a product tag) attached to a product sold at a store where the POS terminal 2 is installed. ), Check if it is. When the CPU 10 confirms that the received tag data is not that of the product tag (Act5, No), it follows the received tag data as tag data read from the RFID tag attached to the product that is not the target of sale. The process returns to reading about another RFID tag (Act4).

On the other hand, when the CPU 10 confirms that the received tag data belongs to the product tag (Act5, Yes), the CPU 10 searches the tag list area 12a using the tag code included in the received tag data as a key (Act6).

When the same tag code as the tag code included in the received tag data is not found in the tag list area 12a (Act7, No), the CPU 10 adds the received tag data to the tag list area 12a and writes it (Act8). The CPU 10 acquires product information (product name, price, etc.) based on the product code included in the received tag data (Act9). For example, the CPU 10 may read the product information corresponding to the product code stored in the auxiliary storage unit 13, or may receive the product information from the store server or the like via the communication network 200. The CPU 10 adds (updates) the product information acquired based on the received tag data to the product list stored in the product list area of the RAM 12 (Act 10).

After updating the product list, the CPU 10 updates the subplanning surface displayed on the touch panel 22 so as to represent the contents of the updated product list (Act 11). The subplanning surface is a screen for displaying a list of product names and prices of products identified based on the read tag data and displaying the subtotal amount. On the sub-planning side, a payment button is also provided to request the start of payment.

Hereinafter, as described above, the processing according to the received tag data read by the tag reader 26 is repeatedly executed (Acts 4 to 11).

The CPU 10 exists in the tag reading chamber of the reading device 1 when the tag code included in the received tag data read by the tag reader 26 is only the same code as the already read tag code stored in the tag list area 12a. Since the tag data has been read from all the RFID tags to be used, the display on the subplanning surface is not updated.

The operator can confirm that the reading of the tag data is completed because the display of the subplan surface is no longer updated (addition of products). Here, the operator can instruct the execution of the payment process by touching the payment button displayed on the subplanning surface. The CPU 10 detects the touch on the payment button and ends the reading operation of the reading device 1.

When the touch operation for the payment button is detected on the touch panel 22 (Act12, Yes), the CPU 10 executes the payment process based on the product information stored in the product list. In the payment process, for example, the purchase target is selected according to the payment method selection (cash, credit card) and the payment operation according to the payment method (cash insertion into the automatic change machine 5 and credit card reading by the card reader 23). Payment is executed for the product to be used.

The CPU 10 causes the touch panel 22 to display a payment end screen on which the payment process is completed (Act 14). Further, the CPU 10 starts measuring the elapsed time after the payment process is completed (or after the payment end screen is displayed).

The CPU 10 causes the printer 24 to issue a receipt representing the result of the payment process (Act 15). That is, the CPU 10 generates a statement showing the product name and amount of the payment process, and a receipt image showing the total amount of payment, the deposit amount, the change amount, and the like, and prints this on the receipt paper by the printer 24. Have it printed. The area on which the receipt image of the receipt paper is printed is separated from the other areas and then discharged from the receipt issuing port 5. The CPU 10 controls the printer 24 to issue a receipt as a certificate when a credit card payment is made. As a result, a receipt using the receipt paper will be issued to the customer. Alternatively, the CPU 10 generates receipt data including the information described in the receipt, and sends the receipt data to, for example, a center server (not shown) via the communication network 200. The customer can access the center server using an appropriate information communication terminal and browse the contents of the receipt data.

In addition, the CPU 10 confirms whether or not change has occurred as a result of the settlement process. Then, when change is occurring (Act16, Yes), the CPU 10 causes the automatic change machine 5 to pay out the change (Act17).

On the other hand, when the elapsed time after the payment process is completed (or after the payment end screen is displayed) reaches a preset time (for example, 8 seconds), the CPU 10 activates the reading operation by the tag reader 26. Then, the tag reading chamber of the reading device 1 is made to execute a reading operation again for detecting the product that has been forgotten to be picked up (Act 18). The preset time is, for example, a time during which the operator can take out the product from the reading device 1 by normal work after the payment processing is completed, and the customer who has completed the payment processing is far away from the POS terminal 2. An appropriate time is set to the extent that it does not go.

When the tag data is not read by the tag reader 26 again reading operation (Act 19, No), the CPU 10 is initialized to process the next customer, assuming that all the products have been taken out from the reading device 1. Execute the process (Act1).

On the other hand, when the received tag data is read by the tag reader 26 again by the reading operation (Act19, Yes), the CPU 10 uses the tag code included in the received tag data as a key to record the tag data that has been settled. Search the list area 12a (Act7).

When the CPU 10 does not find the same tag code as the tag code included in the received tag data in the tag list area 12a by searching the tag list area 12a (Act21, No), all the products are taken out from the reading device 1. As a result, the initialization process is executed in order to process the next customer (Act1). That is, the above-mentioned re-reading operation is executed when the elapsed time after the settlement process is completed (or after the settlement end screen is displayed) becomes a preset time. Therefore, after the product is taken out from the reading device 1, the reading operation (Act 18) may be executed again in a state where the opening / closing lid 1b is not closed. In this case, the tag reader 26 is attached to an RFID tag attached to a product around the reader 1 whose payment processing has not been completed, for example, a product not to be purchased by the customer (such as a product to be purchased by the next customer). May read data. Therefore, even if the tag data is read, it is not forgotten to take the product, so the process shifts to the initialization process.

On the other hand, when the same tag code as the tag code included in the received tag data is found in the tag list area 12a by the search of the tag list area 12a (Act21, Yes), the CPU 10 picks up the product on the touch panel 22. A message warning of forgetting is displayed (Act22). Further, an error sound indicating a warning may be output from a speaker (not shown).

For example, if the work of taking out the products from the reading device 1 is not performed even after the preset time has elapsed after the payment processing is completed, all the products remain in the tag reading chamber of the reading device 1. Up to. Therefore, it is determined that the same tag code as the received tag data is stored in the tag list area 12a.

Further, even when the product is taken out from the reading device 1 within a preset time after the payment processing is completed, for example, when the product basket in which the products are piled up is taken out from the reading device 1. , The product may fall from the product basket and be left in the tag reading room. In such a case, a message is output because the received tag data read from the RFID tag attached to the product left in the tag reading room matches the tag data for which payment processing has been completed. Similarly, when only the products are stored in the reading device 1 without using the product basket and all the products are not taken out after the payment processing, a message is displayed.

FIG. 5 is a diagram showing an example of the message display screen SC in the present embodiment.
On the message display screen SC shown in FIG. 5, for example, the message 50 "Please check if there are any products that you have forgotten to take." Is displayed. Further, the message display screen SC is provided with a clear button 52 for instructing to delete the message.

By displaying the message display screen on the touch panel 22, the operator is urged to confirm whether or not the product is left in the tag reading chamber of the reading device 1. When a touch operation on the clear button 52 of the message display screen SC is detected (Act23, Yes), the CPU 10 erases the message display screen SC (Act24) and performs an initialization process to process the next customer. Execute (Act1). That is, the operator cannot move to the next customer processing unless he / she confirms the message display screen SC and operates the clear button 52. Therefore, it is possible to make the operator surely confirm that the product has been forgotten to be picked up.

In this way, in the product data processing device 100 (POS terminal 2) of the present embodiment, even if the product for which the payment processing has been completed is forgotten to be taken from the tag reading chamber of the reading device 1, the product is again after the payment processing by the tag reader 26. The tag data can be read and a message can be output by the reading operation of. As a result, the operator can be made to confirm that the tag reading chamber of the reading device 1 has not forgotten to pick up the product, and it is possible to reliably prevent the product from being forgotten to be picked up.

In the above description, the re-reading operation for detecting the forgotten product after the settlement process is executed only once (Act18), but it may be executed a plurality of times. For example, when the tag data is read from the RFID tag attached to the product whose payment has been processed by the reading operation (second time) again, the message is displayed as described above (Act 22). Then, after a preset time (for example, 5 seconds) has elapsed from displaying the message, the tag reader 26 executes the reading operation (third time) again. This makes it possible to reliably check for forgetting to take the product. In addition, when the tag data is read by the reading operation again, a message having different contents may be output each time.

Further, in the above description, when the elapsed time after the payment process is completed (or after the payment end screen is displayed) reaches a preset time, the tag reader 26 executes the reading operation again. However, it is also possible to execute the reading operation again after detecting that the product has been taken out from the reading device 1 after the payment processing. That is, the CPU 10 causes the tag reader 26 to execute the reading operation again after it is determined that the product has been excluded from the reading target by the tag reader 26.

For example, in the CPU 10, after the settlement process is completed, the open / close sensor 27 of the reading device 1 notifies that the open / close lid 1b has been opened, and then the open / close sensor 27 again closes the open / close lid 1b. When it is notified, it is determined that the product has been taken out.

Alternatively, the CPU 10 causes the touch panel 22 to display a confirmation button for the operator to input that the removal of the product from the reading device 1 is completed after the payment processing is completed. After taking out the product from the reading device 1, the operator touches the confirmation button. When the CPU 10 detects a touch operation on the confirmation button, it determines that the product has been taken out.

The method for detecting that the product has been taken out from the reading device 1 (the product has been excluded from the reading target by the tag reader 26) may be a method other than the above-mentioned method. When the CPU 10 determines that the product has been excluded from the reading target by the tag reader 26 as described above, the CPU 10 causes the tag reader 26 to execute the reading operation again as described above.

Further, in the above description, a checkout system provided with a product data processing device 100 (POS terminal 2) operated by a store clerk (casher) is taken as an example, but the customer mainly performs operations for payment processing. It can also be applied to self-type or semi-self-type check systems. In the product data processing device provided in both the self-type and semi-self-type checkout systems, basically the same processing as the processing shown in the flowcharts of FIGS. 3 and 4 described above is executed to have the same effect and effect. Can be obtained. For example, after the payment process is completed, a message notifying the customer of the payment completion (for example, "Thank you for using") is displayed, and after a certain period of time (for example, several seconds) has elapsed, the tag reader 26 rereads the message. Let it run. Here, when the tag data is read from the RFID tag attached to the product that has been forgotten in the tag reading room, a message (display or voice) is output to notify the customer that the product has been forgotten to be removed. ..

Further, in the above description, although the reading device 1 and the POS terminal 2 are configured by separate housings, it is also possible to configure the reading device 1 and the POS terminal 2 as an integrated product data processing device 100. be. Further, the shape of the tag reading chamber of the reading device 1 is not limited to the box shape as shown in FIG. 1, and can be configured by any shape and size according to the products handled in the store. Further, when the tag data read by the tag reader 26 can be specified only as the tag data read from the RFID tag attached to the product to be purchased by the customer, the tag data is stored in the tag reading chamber of the reading device 1. It is not necessary to execute the reading operation by the tag reader 26. For example, by adjusting the radio waves transmitted from the tag reader 26 so as not to reach other than the products to be purchased by the customer, it is not necessary to store the products in the tag reading chamber.
