Further, the control unit 100 displays the product C put in the plastic shopping bag F in the area G2.

FIG. 8 is a diagram showing a display screen in which the camera B26 images the operation of the customer putting the product into the plastic shopping bag F, and the control unit 100 displays the image operated by the customer in the area G2. In FIG. 8, in the area G2, the product C is put into the shopping bag F by the customer's hand T. Product A, product B, and product D are displayed in the area G1.

The control unit 100 determines whether or not there is a change (that is, movement of the product from the basket K) in the image of the product displayed in the area G1 of the display unit 22 (S21). When the product labeled and displayed in the area G1 is no longer displayed, the control unit 100 determines that the image of the product displayed in the area G1 has changed. When it is determined that there is a change (Yes in S21), then the control unit 100 (reception means 102) determines whether or not the input of the product code read by the reading unit 23 has been accepted (S22). If it is determined that the product has been accepted, the control unit 100 (Yes in S22) executes the sales registration process based on the received product code (S23). That is, the control unit 100 reads the product information (product code, product name, price, etc.) of the product corresponding to the product code from the product master (not shown) based on the received product code, and the product information unit 100. Store in 131. Then, the control unit 100 displays the stored product information in the area G3 (S24). Then, the control unit 100 returns to S21.

On the other hand, in S21, when it is determined that there is no change in the image of the product displayed in the area G1 of the display unit 22 (No in S21), the control unit 100 inputs the product code read by the reading unit 23. Is determined whether or not the product has been accepted (S31). If it is determined that the information has been accepted (Yes in S31), the control unit 100 (error notification means 103) executes error processing for displaying (notifying) error information on the display unit 22 (S32). When S21 is No and S31 is Yes, it means that the input of the product code is accepted even though the product is not taken out from the basket K. The control unit 100 executes error processing on the assumption that this may be an illegal act in which the customer takes out the product from a place other than the basket K and causes the reading unit 23 to read the product code. In this case, the attendant who monitors the self-POS terminal 1 investigates the error and cancels the error state. The control unit 100 determines whether or not the error state has been cleared (S33). It waits until it is released (No in S33), and if it is determined that it has been released (Yes in S33), the control unit 100 returns to S21.

Further, when the input of the product code is not accepted in S22 (No of S22), it means that the product is not input even though the product is taken out from the basket K, and the error processing is executed in the same manner. (S32).

Further, when it is determined in S31 that the input of the product code is not accepted (No in S31), the control unit 100 then determines whether or not the image of the product displayed in the area G2 has changed. (S34). When a new product is displayed in the area G2 (Yes in S34), the control unit 100 determines that the image of the product displayed in the area G2 has changed. In S34, the fact that the image of the product displayed in the area G2 has changed means that the product has been put into the shopping bag F even though there is no change in the area G1 and the input of the product code is not accepted. Therefore, the control unit 100 executes error processing on the assumption that there is a possibility of an illegal act of taking out the product from other than the basket K and putting the product in the shopping bag F without inputting the product code of the product. (S32).

On the other hand, when it is determined that there is no change in the image of the product displayed in the area G2 (No in S34), the control unit 100 then determines whether or not the end key 212 displayed on the display unit 22 has been operated. Is determined (S41). If it is determined that the operation has been performed (Yes in S41), the accounting process is executed based on the product information stored in the product information unit 131 (S42). At this time, a receipt is issued in which the product information and the accounting information of the accounted product are printed by the printing unit 24. Then, the control unit 100 ends the imaging with the camera A25 and the camera B26 (S43). Then, the control unit 100 ends the display of the display screen displayed on the display unit 22 (S44). Then, the control unit 100 returns to S11. If it is determined in S41 that the end key 212 has not been operated (No in S41), the control unit 100 returns to S21.

According to such an embodiment, the camera A25 takes an image of the product inside the basket K mounted on the basket mounting table 31. Further, the camera A25 captures the operation of the customer who takes out the product from the basket K. On the other hand, the camera B26 takes an image of the product put in the plastic shopping bag F set on the plastic shopping bag stand 32. Further, the camera B26 captures the operation of the customer who puts the product in the shopping bag F. Then, the control unit 100 displays the image captured by the camera A25 and the image captured by the camera B26 on the display unit 22. That is, the control unit 100 displays the products inside the basket K imaged by the camera A25. Further, the control unit 100 displays the customer's operation of taking out the product from the basket K imaged by the camera A25. Further, the control unit 100 displays the products put in the plastic shopping bag F imaged by the camera B26. Further, the control unit 100 displays the operation of the customer who puts the product in the plastic shopping bag F imaged by the camera B26.

In this way, in the self-POS terminal 1 of the embodiment, the customer's operation in the self-POS terminal 1 is displayed on the display unit 22, and the customer performs the self-POS terminal 1 operation while observing his / her own operation. Therefore, since the customer recognizes that his / her operation is captured by the camera, it is possible to suppress the fraudulent operation by the customer.

In the embodiment, the camera A25 is used to image the products inside the basket K placed on the basket mounting table 31 and the operation of the customer who takes out the products from the basket K.
