  However, in a conventional merchandise sales registration processing system using a radio tag reader that collectively reads tag information, a product with a radio tag and a product without a radio tag are sold together. No measures were taken into account. In other words, if a product with a wireless tag and a product without a wireless tag are mixed and placed in a shopping basket, the cashier registers through the RFID tag reader from each product in the shopping basket. Although it is necessary to distinguish between the merchandise that has been registered and the merchandise that has not been registered, it has been difficult to easily distinguish the merchandise from the conventional system. Therefore, even if a product sales registration processing system using a wireless tag is introduced, the efficiency of product registration work may be reduced.

  The present invention has been made based on such circumstances, and an object of the present invention is to easily distinguish between products for which sales information is registered and unregistered products by batch reading of wireless tags by a wireless tag reader. Therefore, an object of the present invention is to provide a product sales registration processing system that can improve the efficiency of product registration work.

  The merchandise sales registration processing system of the present invention collects tag information collectively from a sales registration section in which merchandise sales information is registered, and a wireless tag attached to each product placed in a reading area at regular intervals. Each time the tag information is collectively read by the wireless tag reading device to be read, the tag information that was read last time but not read this time is searched, and when the corresponding tag information is detected, Means for acquiring product sales information from the tag information and registering it in the sales registration unit; informing means for informing operation in response to detection of tag information that was read last time but not read this time; and input means When information related to the sales product is input via the, the sales information of the product is acquired from the input information and is registered in the sales registration unit. Accordingly, the sales information is registered by the operator taking out the product with the wireless tag from which the tag information has been read by the wireless tag reader from the reading area of the wireless tag reader. At this time, the operator recognizes that the sales information of the taken-out product has been registered when the notification means performs a notification operation when the product is taken out from the reading area of the wireless tag reader. When the notification means does not perform the notification operation, it is determined that the sales information of the extracted product has not been registered, and the operator inputs information related to the sales product of the product via the input means and performs registration processing in the sales registration unit. To do.

  According to the merchandise sales registration processing system of the present invention in which such measures are taken, the wireless tag is collectively read depending on the presence or absence of a notification operation when a product placed in the reading area of the wireless tag reader is moved out of the reading area. Thus, it is possible to easily distinguish a product for which sales information has been registered from an unregistered product. Therefore, the efficiency of product registration work can be improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 3 is a block diagram showing a main configuration of the POS terminal 1. The POS terminal 1 includes a CPU (Central Processing Unit) 21 constituting a control unit main body, a ROM (Read Only Memory) 22 in which program data for the CPU 21 to control each unit, and the CPU 21 calculates data. A RAM (Random Access Memory) 23 having various memory areas used for display, printing, input / output processing, a memory area for temporarily storing data, a clock unit 24 for measuring the current date and time, and the POS A communication interface 25 that performs data communication with the server 6, a display device interface 26 that transmits display data to the display device 4, a barcode reader interface 27 that receives barcode data from the barcode reader 3, and the wireless tag reader Wireless tag reader interface 28 for receiving tag information from 2; An input / output (I / O) port 29 for inputting a detection signal from the recording sensor 5, a keyboard controller 30 for controlling key input of the keyboard 11, a display controller 31 for controlling screen display of the operator display 12, A display controller 32 for controlling the screen display of the customer display 13 and a printer controller 33 for controlling the printing operation of the printer 14 are provided. The CPU 21, ROM 22, RAM 23, clock unit 24, I / O port 29, interfaces 26 to 28, and controllers 30 to 33 are connected by a bus line 34 such as an address bus and a data bus.

  In the POS terminal 1 having such a configuration, in the RAM 23, as shown in FIG. 4 in particular, in addition to a product registration memory 41 in which product information of sales products is registered, a registration amount totaling unit 42, a registered number counter 43, a display option Various memory areas such as a memory 44, a tag information memory 45, and a tag information number counter 46 are formed. The registered amount totalizer 42 is an area where the registered amounts of products purchased by one shopper are totaled. The registration number counter 43 is an area for counting the number M of registration points of products purchased by one shopper.

  The tag information memory 45 stores the storage information (ID, product code) of the wireless tag 10 collectively read by the wireless tag reader 2, product information (product name, unit price, product image, etc.) corresponding to the product code, and each tag information. Is an area for temporarily storing the processed flag F0. The tag information number counter 46 is an area for counting the number N of unprocessed tag information among the tag information stored in the tag information memory 45.

  The display option memory 44 is an area for storing option information OP corresponding to a format selected and specified from among a plurality of information display formats for the display device 4. The information display format is specified by option information OP = 1 to 3.

  The CPU 21 controls from the registration of the sales merchandise purchased by one shopper to the settlement of the price according to the procedure shown in the flowchart of FIG. That is, the CPU 21 waits for an ON signal from the bag sensor 5 as an initial state after the settlement of the previous customer is completed (ST1). When the shopping basket 9 is placed in the reading area of the wireless tag reader 2 and an ON signal is output from the basket sensor 5, the CPU 21 instructs the wireless tag reader 2 to start a reading operation (ST2).

  As a result, the wireless tag reader 2 starts a reading operation, collectively reads the tag information of the wireless tag 10 attached to each product placed in the reading area, and collects the collectively read tag information together at the POS terminal. 1 to send. The wireless tag reader 2 repeats this reading operation at a constant interval (for example, every 1 second), and transmits the tag information read at once to the POS terminal 1 each time.

  After instructing the wireless tag reader 2 to start the reading operation, the CPU 21 waits for tag information to be sent from the wireless tag reader 2 (ST3). Then, when receiving the first tag information collectively read by the wireless tag reader 2, the CPU 21 acquires the product code from each tag information, and product information (product name, unit price, product image, etc.) corresponding to each product code. From the product database 6A of the POS server 6. Then, all tag information initially read by the wireless tag reader 2 is paired with product information corresponding to the product code in the tag information, and a processed flag F0 indicating unprocessed “0” is attached. Store in the tag information memory 45 (ST4). Further, the CPU 21 counts and stores the number N of tag information stored in the tag information memory 45 using the tag information number counter 46 (ST5).

  Next, the CPU 21 checks the option information OP set in the display option memory 44 (ST6). When “1” indicating the first information display format is set as the option information OP, the CPU 21 stores the product name corresponding to the product code in all the tag information stored in the tag information memory 45. To display a list on the display device 4. Further, the count value N (number of tag information) of the tag information number counter 46 is also displayed on the display device 4 as the number of product readings (ST7). When the other option information OP is set, the CPU 21 displays no information on the display device 4 at this time.

  Thereafter, the CPU 21 sends from the wireless tag reader 2 tag information that has been read next by the wireless tag reader 2 (ST8), or receives barcode information from the barcode reader 3 (ST9). The system waits for key input on the keyboard 11 (ST10).

  The CPU 21 executes tag registration processing specifically shown in the flowchart of FIG. 6 every time the tag information sent from the wireless tag reader 2 at a predetermined interval is input. That is, the CPU 21 searches whether or not the tag information (ID, product code) stored in the tag information memory 45 exists in the tag information read this time (ST21: search means). If all IDs stored in the tag information memory 45 are present in the tag information read this time (ST22), the CPU 21 ends the tag registration process.

  On the other hand, when an ID that does not exist in the RFID tag information read this time is detected in the tag information ID stored in the tag information memory 45, the CPU 21 performs the following for the ID. Execute the process. That is, the CPU 21 searches the tag information memory 45 and determines whether or not the processed flag F0 corresponding to the ID is set to “1” (ST23). If it is set to “1”, the process for the ID is terminated.

  When the processed flag F0 corresponding to the ID is reset to “0”, the CPU 21 searches the tag information memory 45 and reads the product code and the product information corresponding to the ID. Then, the unit price in the product information is set as the sales amount, and “1” is set as the sales point, and the product sales information including the product code, the sales amount, and the sales point is registered in the product registration memory 41 (ST24: first product). Sales registration processing means). Further, the registered sales amount is added to the registered amount totalizer 42, and the registration number counter 43 is incremented by "1" (ST25). And the processed flag F0 memorize | stored corresponding to the said ID in the tag information memory 45 is set to "1" (ST26).

  Thereafter, the CPU 21 checks the option information OP set in the display option memory 44 (ST27). Here, when “1” is set as the option information OP, the CPU 21 subtracts the count value N of the tag information number counter 46 by “1” (ST28), and then is displayed on the display device 4. The product name corresponding to the ID is changed to a special display, for example, black and white reverse display, and the product read count is changed to the count value N of the tag information count counter 46, and the sales information of the product is registered. Is notified to the cashier (ST29: notification means).

  On the other hand, when “2” indicating the second information display format is set as the option information OP, the CPU 21 stores the product name corresponding to the ID read from the tag information memory 45 and the registered number counter. The count value N of 43 is displayed on the display device 4 to notify the cashier that the sales information of the product has been registered (ST30: notification means).

  If “3” indicating the third information display format is set as the option information OP, the CPU 21 displays the product name and product image corresponding to the ID read from the tag information memory 45. 4 to notify the cashier that the sales information of the product has been registered (ST31: notification means).

  Thus, the CPU 21 ends the process for the ID. Thereafter, every time the CPU 21 detects an ID that does not exist in the RFID tag information read this time among the IDs stored in the tag information memory 45, the CPU 21 executes each process of ST22 to ST33 on the ID. . When the search process is completed for the ID stored in the tag information memory 45, the wireless tag registration process is terminated.

  When the barcode information is sent from the barcode reader 3, the CPU 21 executes barcode registration processing specifically shown in the flowchart of FIG. First, the CPU 21 acquires a product code as information related to a sales product from the input barcode information (ST41). Next, the CPU 21 compares the product code of the product sales information registered immediately before in the product registration memory 41 with the product code acquired from the barcode information input this time (ST42). If the product codes do not match, the process proceeds to ST47.

  If the two product codes match, the CPU 21 warns the operator of duplicate registration (for example, “The product registered in the barcode is the same as the product registered immediately before? Are you sure?”) Is displayed on the display device 4 (ST44). If cancellation is instructed by a key operation on the keyboard 11 (ST45), the CPU 21 deletes the duplicate registration warning display and ends the current barcode registration process. On the other hand, when execution is instructed by key operation of the keyboard 11 (ST46), the CPU 21 deletes the duplicate registration warning display and proceeds to the process of ST47.

  When a product code different from the immediately preceding registered product is input by scanning, or when a product code that matches the immediately preceding registered product is input by scanning but execution is instructed by a key operation, the CPU 21 obtains from the barcode information. The product information (product name, unit price, product image, etc.) corresponding to the selected product code is fetched from the product database 6A of the POS server 6. Then, the unit price in the product information is set as the sales amount, and “1” is set as the sales point, and the product sales information including the product code, the sales amount and the sales point is registered in the product registration memory 41 (ST47: second). Product sales registration processing means). In addition, the registered sales amount is added to the registered amount totalizer 42, and the registered number counter 43 is incremented by "1" (ST48).

  Thereafter, the CPU 21 checks the option information OP set in the display option memory 44 (ST49). If “1” is set as the option information OP, the CPU 21 displays the product name in the product information acquired from the product database 6A on the display device 4 in a special display form (ST50). When “2” is set as the option information OP, the CPU 21 displays the product name in the product information and the count value N of the registered number counter 43 on the display device 4 (ST51). When “3” is set as the option information OP, the CPU 21 displays the product name and product image in the product information on the display device 4 (ST52). Thus, the CPU 21 ends the current barcode registration process.

  Further, when detecting a key input on the keyboard 11, the CPU 21 executes a process corresponding to the key input. Here, when it is detected that the closing key for declaring the end of registration of the sales merchandise purchased by one shopper is detected, the CPU 21 instructs the wireless tag reader 2 to end the reading operation (ST12). Further, the CPU 21 executes a normal registration closing process including a clearing process and a receipt issuing process for the total amount stored in the registered amount totalizer 42 (ST13). And CPU21 complete | finishes the control processing with respect to this 1 shopper.

  In the retail store where the merchandise sales registration processing system of the present embodiment configured as described above is constructed, when the shopper puts the merchandise desired to be purchased into the shopping basket 9 and reaches the checkout counter 7, the cashier The shopping basket 9 is placed in the wireless tag reading area of the checkout counter 7. Then, the wireless tag reader 2 starts a reading operation, and the stored information of the wireless tags 10 attached to the respective products accommodated in the shopping basket 9 is read all at once.

  As an example, there are a total of four points, “XX cookies”, “XX cup noodles” and “□□ coffee” with a wireless tag 10 attached, and “△△ juice” without a wireless tag 10 attached. Assume that the stored shopping basket 9 is placed in the reading area of the wireless tag reader 2.

  In this case, if the stored information of the wireless tag 10 attached to each of “XX cookie”, “XX cup noodle”, and “□□ coffee” is normally read by the wireless tag reader 2, the display option OP is set. When “1” is set, as shown in FIG. 8A, the product names of the three items from which the tag information has been normally read and the product reading number “3” are displayed on the display device 4. The When “2” or “3” is set as the display option OP, no information is displayed on the display device 4 as shown in FIG. 9A or 10A.

  Next, the cashier prepares an empty shopping basket 9 ′ outside the store from the bar code reader 3 of the checkout counter 7. Then, the commodity is taken out from the shopping basket 9 and moved to the empty shopping basket 9 '. For example, assume that the product “□□ coffee” is moved first. Then, the tag information of the wireless tag 10 attached to the product “□□ coffee” is not read when the product “□□ coffee” is out of the reading area of the wireless tag reader 2. Sales information of “□□ coffee” is registered in the product registration memory 41. If “1” is set as the display option OP, as shown in FIG. 8B, the product name of the product “□□ coffee” is displayed in a special display such as black and white reversal and the number of product readings Is subtracted to “2”. When “2” is set as the display option OP, as shown in FIG. 9B, the product name of the product “□□ coffee” and the number of product registration “1” are displayed on the display device 4. . When “3” is set as the display option OP, the product name and product image of the product “□□ coffee” are displayed on the display device 4 as shown in FIG. Therefore, since the display contents of the display device 4 have been changed, the cashier is that the product “□□ coffee” taken out from the shopping basket 9 is a product whose sales information has been registered via the wireless tag reader 2. Can be recognized. The cashier then puts the product “□□ Coffee” into an empty shopping basket 9 ′.

  Next, it is assumed that the cashier takes the product “ΔΔ juice” from the shopping basket 9 and moves it to the empty shopping basket 9 ′. Then, since the product “ΔΔ juice” is not attached with a wireless tag, the display content of the display device 4 is not changed regardless of the display option OP. Therefore, since the display content of the display device 4 has not been changed, the cashier has the product “△△ juice” taken out of the shopping basket 9 as a product whose sales information has not been registered via the wireless tag reader 2. You can recognize that there is. Accordingly, the cashier causes the bar code attached to the product “ΔΔ juice” to be read by the bar code reader 3 to register the sales information, and then put it into the shopping basket 9 ′. At this time, if “1” is set as the display option OP, as shown in FIG. 8C, a special display form in which the product name of the product “Δ Juice” is displayed on the display device 4 is reversed in black and white. The number of items read is not changed. When “2” is set as the display option OP, as shown in FIG. 9C, the product name of the product “Δ Juice” is additionally displayed on the display device 4 and the number of registered products is “ 2 ”. When “3” is set as the display option OP, as shown in FIG. 10C, the product name and product image of the product “Δ Juice” are additionally displayed on the display device 4.

  Next, it is assumed that the cashier takes the product “XX cookie” from the shopping basket 9 and moves it to the shopping basket 9 ′. In this case, as with the product “□□ coffee”, the sales information of the product “XX cookies” is registered and displayed when the product “XX cookies” is out of the reading area of the wireless tag reader 2. The display content of the device 4 is changed together with the display option OP.

  Here, when the cashier moves the product “XX cookie” to the shopping basket 9 ′, the bar code pre-printed on the product “XX cookie” is directed to the reading surface 3 a of the barcode reader 3. It is assumed that the barcode is read by the barcode reader 3 because the barcode is moved. In this case, since the barcode of the product registered immediately before matches the barcode of the product input by scanning, a duplicate warning is displayed on the display device 4. Therefore, the cashier gives a cancellation instruction by operating the key. Thereby, it is possible to prevent the sales information of the product “XX cookie” from being registered repeatedly by the wireless tag reader 2 and the barcode reader 3.

  In this way, when all the goods stored in one shopping basket 9 are transferred to the other shopping basket 9 ', the cashier operates the closing key of the keyboard 11 to execute the registration closing process. Thereby, the tag reading operation of the wireless tag reader 2 is stopped until the next customer's shopping basket 9 is placed in the reading area.

  As described above, according to the present embodiment, the cashier can wirelessly perform the simple operation of taking out the product from the shopping basket 9 placed in the reading area of the wireless tag reader 2 and moving it out of the reading area. It is possible to easily distinguish whether the sales information is a product for which sales information is registered or a product for which sales information has not been registered by batch reading of the wireless tag 10 by the tag reader 2. Therefore, even when a product with the wireless tag 10 and a product without the wireless tag 10 are mixed, the cashier confirms whether or not the wireless tag 10 is attached to the product picked up from the shopping basket 9. Since there is no time and effort, workability can be improved. Further, the wireless tag reader 2 cannot read the tag information because the wireless tag 10 is out of order or overlaps with the wireless tag 10 attached to another product in the shopping basket 9 or a metallic product. Even in this case, in the present embodiment, this type of product can be easily distinguished, so the effect is great.

  By the way, as a case where tag information cannot be read by the wireless tag reader 2, in addition to the failure of the wireless tag 10, there may be a case where it overlaps with another wireless tag 10 or metal as described above. In such a case, in the first embodiment, the sales information of the product is registered by barcode scanning registration. However, for products for which the wireless tag 10 is functioning normally, it is desirable that the sales information can be registered based on the tag information of the wireless tag 10. In the future, there may be a case where a product without a barcode is present among the products with the wireless tag 10 attached. Of course, it is possible to register the sales information for the product without the barcode attached, for example, by inputting the product code as a key. In this case, however, a great effort is required for the cashier. Therefore, for products that are not registered by batch reading by the wireless tag reader 2 even though the normal wireless tag 10 is attached, sales information is separately obtained based on the tag information of the wireless tag 10. A second embodiment that allows registration processing will be described with reference to the drawings.

[Second Embodiment]
FIG. 11 is a block diagram of a product sales registration processing system according to the second embodiment, and FIG. 12 is a schematic diagram of a check-out unit in which the product sales registration processing system is introduced. This system differs from the first embodiment in that the bar of the counter 7 is separate from the first RFID tag reader 2 provided with antennas 2A and 2B inside the store rather than the bar code reader 3 of the checkout counter 7. A second wireless tag reader 51 having an antenna 51A provided outside the store than the code reader 3 is provided, and the second wireless tag reader 51 is connected to the wireless tag reader interface 28 of the POS terminal 1 like the first wireless tag reader 2. The other points are the same as in the first embodiment. The antenna 51A is installed between the barcode reader 3 and the place where the empty shopping basket 9 'is arranged, and the tag reading area of the second wireless tag reader 51 is a product taken out from the shopping basket 9 by the cashier CA. Are formed in the path of travel to the empty shopping basket 9 '. In addition, when the second wireless tag reader 51 outputs an ON signal from the bag sensor 5, it receives a command for starting a reading operation from the CPU 21, starts a reading operation, and inputs a closing key for declaring the end of sales product registration. Then, a reading operation end command is received from the CPU 21, and the reading operation is ended.

  In such a configuration, the CPU 21 of the POS terminal 1 controls from the registration of sales merchandise purchased by one shopper to the settlement of the price according to the procedure shown in the flowchart of FIG. In FIG. 13, the same components as those in FIG. 5 showing the same control in the first embodiment are denoted by the same reference numerals.

  That is, in this control, the present embodiment is different from the first embodiment in that the first tag information that is collectively read by the first wireless tag reader 2 is acquired and then the first wireless tag reader 2 Is received (ST8), whether the barcode information is sent from the barcode reader 3 (ST9), whether the tag information is sent from the second wireless tag reader 51 (ST14), This is a point to wait for key input on the keyboard 11 (ST10). When barcode information is sent from the barcode reader 3 or when a key input is performed, the same processing as in the first embodiment is performed. As with the first wireless tag reader 2, the second wireless tag reader 51 also starts the reading operation in response to the ST2 processing command and stops the reading operation in response to the ST12 processing command.

  On the other hand, when receiving tag information sent from the first wireless tag reader 2 at regular intervals, the CPU 21 executes tag registration processing specifically shown in the flowchart of FIG. In FIG. 14, the same parts as those in FIG. 6 showing the same processes of the first embodiment are denoted by the same reference numerals.

  That is, in this tag registration process, this embodiment is different from the first embodiment in that, when an ID that does not exist in the tag information read this time is detected, sales information corresponding to the ID is displayed. After sales registration processing in the merchandise registration memory 41, tag information of the ID is stored in a registered memory formed in the RAM 23 (ST32), and the others are the same as in the first embodiment.

  The second wireless tag reader 51 reads the tag information of the wireless tag attached to the product and transmits it to the POS terminal 1 when the product taken out from the shopping basket 9 by the cashier CA passes through the tag reading area. When the CPU 21 receives the tag information transmitted from the second wireless tag reader 51, the CPU 21 executes a second tag registration process specifically shown in the flowchart of FIG. First, the CPU 21 searches whether or not the ID of the tag information read this time exists in the ID of the tag information stored in the registered memory (ST61). If the ID of the tag information read this time is present in the ID of the tag information stored in the registered memory (ST62), the CPU 21 ends the second tag registration process.

  On the other hand, if the ID of the tag information read this time does not exist in the tag information ID stored in the registered memory, the CPU 21 stores the tag information of the ID in the registered memory. (ST63).

  Next, the CPU 21 acquires a product code from the tag information of the ID (ST64). Then, the product information (product name, unit price, product image, etc.) corresponding to this product code is fetched from the product database 6A of the POS server 6, the unit price in this product information is set as the sales price, and “1” is set as the sales point. The product sales information including the product code, the sales price, and the sales points is registered in the product registration memory 41 (ST65: second product sales registration processing means). Further, the registered sales amount is added to the registered amount totalizer 42, and the registration number counter 43 is incremented by "1" (ST66).

  Thereafter, the CPU 21 checks the option information OP set in the display option memory 44 (ST67). If “1” is set as the option information OP, the CPU 21 displays the product name in the product information acquired from the product database 6A on the display device 4 in a special display form (ST68). When “2” is set as the option information OP, the CPU 21 displays the product name in the product information and the count value N of the registered number counter 43 on the display device 4 (ST69). When “3” is set as the option information OP, the CPU 21 displays the product name and product image in the product information on the display device 4 (ST70). Thus, the CPU 21 ends the current second tag registration process.

  According to the second embodiment configured as described above, although the normal wireless tag 10 is attached, the product is not registered by the batch reading by the first wireless tag reader 2. However, since the sales information is automatically registered by the cashier moving the merchandise from one shopping basket 9 to the other shopping basket 9 ', workability can be improved.

  Further, when the tag information is read by the first wireless tag reader 2, the product for which the sales information has been registered is transferred from the shopping basket 9 to the shopping basket 9 ′, and the tag is read by the second wireless tag reader 51. Even if the information is read, since the tag information of the product is stored in the registered memory at the time when the sales information is registered, there is no possibility that the sales information is registered again.

The present invention is not limited to the above embodiment.
For example, in the above-described embodiment, the antenna 51A is installed between the barcode reader 3 and the place where the empty shopping basket 9 'is arranged. However, the antenna 51 is embedded in the checkout counter 7 and placed on the embedded antenna. Even if an empty shopping basket 9 ′ is placed, the sales information can be automatically registered by moving products that have not been registered by batch reading by the first wireless tag reader 2 to the shopping basket 9 ′.

  In the above embodiment, the cashier takes out the products one by one from the shopping basket 9. However, even if a plurality of, for example, two products are taken out simultaneously and moved to the other shopping basket 9 ', the display is displayed. It is possible to easily recognize whether or not the sales information of the extracted product has been registered via the wireless tag reader 2 depending on whether or not the display content of the device 4 has changed.

  For example, when two items are taken out from the shopping basket 9 at the same time, if the information stored in the wireless tag 10 is read by the wireless tag reader 2 for both items, the names of the two items are changed to special display or Since the product name and product image are additionally displayed, the cashier can recognize that both of these two items have been registered. In addition, when the wireless tag 10 is not attached to one product, only the product name of the other product is changed to a special display or a product name or product image is additionally displayed. It can be recognized that one product for which special display has been changed or a product name or product image is additionally displayed has been registered, but the other product has not been registered. Further, when the wireless tag 10 is not attached to both products, the display content of the display device is not changed, so that it can be recognized that both have not been registered.

  Therefore, the working time of the registration work can be greatly shortened as compared with the conventional merchandise sales registration processing system having only the bar code specification that has to be taken out from the shopping basket 9 one by one. In addition, it is not always necessary to place each product in the shopping basket 9 on the checkout counter 7, and the product can be used as it is in the reading area of the wireless tag reader 2. It is.

  In the above embodiment, the display option memory 44 is provided and any one of the first to third information display formats is selectively set. However, the display option memory 44 is fixed to any one format. Thus, the display option memory 44 may be omitted. Moreover, in the said embodiment, the product name of the goods with which the wireless tag collectively read by the wireless tag reader 2 was attached as a 1st information display format is displayed all at once, and the number of tag information collectively read is displayed. After that, the product name of the product for which product information has been registered is changed to a special display such as black and white reversal, and the number of tag information is subtracted, but the product name is black and white reversal, font change, strikethrough display, etc. The tag information counter 46 may be omitted only for the special display. Conversely, even if only the number of tag information is displayed, the number of tag information changes each time product information is registered through the wireless tag reader 2, so that the cashier can be notified. In this case, a simple small display capable of displaying only the number of tag information can be applied as the display device 4.

  In the embodiment, each time tag information that has been read by the wireless tag reader 2 but not read this time is detected, a product name or product image corresponding to the product code included in the tag information is displayed. However, the notifying means is not limited to the display, and for example, the corresponding product name is pronounced by voice to notify the cashier. You may do it.

  In the embodiment, the sales information of the product set with the product code included in the tag information is registered until tag information that has been read by the wireless tag reader 2 but not read this time is detected. However, the sales information of the product may be registered when the tag information is first read by the wireless tag reader 2.
