(Overview of each operation mode)
Subsequently, the operation mode of the POS terminal 20 will be described. The POS terminal 20 has a plurality of operation modes. For example, the POS terminal 20 has a normal mode, a full self mode, and a semi-self mode. In addition, the operation mode described below is an operation mode during normal business (operation mode related to product registration processing and accounting processing), and an aggregation mode for totaling and inquiring sales, sales, etc., a clerk, a maintenance staff, etc. It does not include the maintenance mode for setting work and maintenance work, and the training mode for newcomers to train. Further, the semi-self mode is an operation mode mainly used when data is transmitted / received between a plurality of POS terminals 20. Here, in order to explain an example of executing the registration process and the settlement process on one POS terminal, the normal mode and the full self mode will be described in detail below.

The registration process is a process that starts when the purchased product is first registered and ends when the registration completion key is operated. The settlement process is a process that starts when the settlement start process is performed and ends when the payout of change is completed. The settlement start process is the first process to start the settlement process, for example, there is a choice of payment method. As a payment method selection, for example, there is an input of money into the change machine 209. By inserting money into the change machine 209, cash payment is selected. As a payment method selection, there are cash payment selected by depositing to the change machine 209, cash payment, payment of various cards such as credit cards, and the like. Customers can select their preferred payment method from these payment methods. These payment methods are selected independently, but multiple payment methods may be selected. For example, if the total amount of purchased items is higher than the charge balance stored in the transportation card, use the entire balance of the transportation card for payment and pay the insufficient amount by cash or credit card. You may do it. The settlement start process can be performed after the registration process is started, but it can also be executed before the registration process is started. Specifically, by depositing cash before the registration process is started, the settlement start process is started before the registration process is started. Therefore, the settlement process including the settlement start process may be started after the registration process is started, or may be started before the registration process is started.

5 and 6 are diagrams illustrating the outline of the operation mode of the POS terminal.
FIG. 5 is a diagram illustrating an outline of a normal mode. FIG. 5A is a schematic diagram showing the flow of processing (product registration processing, accounting processing) and the operation of people (clerks, customers) in the normal mode. FIG. 5B is a flowchart showing the basic flow of operation of the POS terminal 20 in the normal mode.
FIG. 6 is a diagram illustrating an outline of the full self mode. FIG. 6A is a schematic diagram showing the flow of processing (product registration processing, accounting processing) and the operation of a person (customer) in the full self mode. FIG. 6B is a flowchart showing the basic flow of operation of the POS terminal 20 in the full self mode.

In the following description, as a different aspect from the classification of the above-mentioned three operation modes (normal mode, full self mode, semi-self mode), the mode in which the POS terminal 20 executes the product registration process is set as the registration mode and the settlement. The mode in which the processing is executed may be referred to as an accounting mode.

(Normal mode)
As shown in FIG. 5A, the normal mode is an operation mode in which the clerk side executes the registration process and the customer side executes the settlement process. That is, as shown in FIG. 5B, in the normal mode, the clerk side is in the registration mode and the customer side is in the accounting mode. That is, the POS terminal 20 operates as a registration accounting mode when viewed throughout the registration process to the settlement process.

In the normal mode, the clerk registers the purchased product of the customer on the clerk side (the clerk side scanner unit 212, the clerk side display unit 210, the key operation unit 211). That is, the POS terminal 20 executes the registration process of the purchased product by the operation of the clerk (operation of the clerk side scanner unit 212, the clerk side display unit 210, the key operation unit 211, etc.) (upper part of FIG. 5A). ..

When the registration process by the clerk is completed, the customer confirms the total amount of the purchased products on the clerk side display unit 210, inserts money into the change machine 209, or operates the card settlement unit 208 to settle the payment (FIG. 5). Lower part of (A)). That is, the POS terminal 20 executes the settlement process by the operation of the customer (inserting money into the change machine 209, operating the card settlement unit 208) (lower part of FIG. 5A).

That is, in the normal mode, as shown in FIG. 5B, the product is initially scanned by the store clerk side scanner unit 212 (step S10: YES) and the product is registered (step S11). After pressing the subtotal key (for example, the subtotal key displayed on the clerk side display unit 210 or the subtotal key arranged on the key operation unit 211) (step S30: YES), on the customer side, for example, the change machine 209. The settlement is performed by (step S50), and the processing is completed. The subtotal key in step S30 is an operation key for completing the registration process, and may be referred to as a subtotal button, a registration completion key, a registration completion button, a checkout key, a checkout button, or the like.

The customer may wait until the registration process by the clerk is completed (until the total amount is fixed), but may insert money into the change machine 209 before the registration process is completed. The payment method may be selected, for example, payment by the card payment unit 208 may be selected. That is, the POS terminal 20 can make a deposit as a settlement start process even before the registration process is completed, for example, before the registration process or during the pedaling force process (upper part of FIG. 5A).

In addition, the clerk may wait after the registration of the purchased product is completed until the payment by the customer is completed (until the customer receives the change or receipt), but the clerk may register the purchased product of the next customer. May be good. That is, the POS terminal 20 can register the purchased product of the next customer during the settlement process (lower part of FIG. 5A). In addition, the clerk may be absent during the payment by the customer (lower part of FIG. 5A). That is, the customer's response may be completed during the settlement of the customer after the registration of the purchased product is completed.

In addition, the POS terminal 20 controls the payout of change / fishing bills by the change machine 209 in order to prevent forgetting to pick up the change when there is change, and a sensor or the like that the customer has removed the change / fishing bill. After recognizing in, the printing unit 213 controls the issuance of the receipt. The control of issuing a receipt after the customer removes the change / fishing ticket is similarly performed in the other operation modes. As described above, in the normal mode, there may or may not be a clerk in front of the customer who receives the change. For example, when there is a clerk, the above-mentioned control does not necessarily have to be performed (that is,). , You may pay out the change / fishing bill and issue the receipt at the same time, or you may issue the receipt first). Further, the timing of paying out change / fishing bills and issuing receipts may be controlled according to the current operation mode and the presence / absence of a clerk (for example, the presence / absence of a clerk is recognized by a sensor).

(Full self mode)
As shown in FIG. 6A, the full self mode is an operation mode in which the customer side executes the registration process and the customer side executes the settlement process. That is, as shown in FIG. 6B, in the case of the full self mode, the customer side is in both the registration mode and the accounting mode. That is, the POS terminal 20 operates as a registration accounting mode when viewed throughout the registration process to the settlement process.

In the full self mode, the customer registers the purchased product on the customer side (customer side scanner unit 206, customer side display unit 205). That is, the POS terminal 20 executes the registration process of the purchased product by the customer's operation (scanning by the customer-side scanner unit 206, touching the customer-side display unit 205) (upper part of FIG. 6A).

When the registration process is completed, the customer confirms the total amount of the purchased products on the customer side display unit 205, inserts money into the change machine 209, or operates the card settlement unit 208 to settle the payment (FIG. 6 (A). ) Lower). That is, the POS terminal 20 executes the settlement process by the operation of the customer (inserting money into the change machine 209, operating the card settlement unit 208) (lower part of FIG. 6A).

That is, in the full self mode, as shown in FIG. 6B, the product is scanned or the like by, for example, the customer side scanner unit 206 (step S20: YES), and the product is registered (step S21). After pressing the registration completion key (for example, the end (receipt) button BT40 displayed on the customer side display unit 205 shown in FIG. 11B) (step S40: YES), on the customer side, for example, by a change machine 209. Settlement is performed (step S50), and the process is completed. The registration completion key according to step S40 is an operation key for completing the registration process, and may be referred to as a registration completion button, a subtotal key, a subtotal button, a checkout key, a checkout button, or the like.

In the full self mode, as described above, the customer side executes both the registration process and the settlement process, but the clerk side does not mean that nothing can be done. That is, even when the POS terminal 20 is operating in the full self mode, for example, the operation of pressing the first mode switching button BT12 displayed on the clerk side display unit 210 shown in FIG. 13B or the like can be performed. It is possible. In the full self mode, as shown in FIG. 13B, before the start of registration, the characters "switch to face-to-face self" are displayed on the second mode switching button BT13. When the customer is registering the purchased product in the full self mode, as shown in FIG. 14B, the character "participate in registration" is displayed on the second mode switching button BT13, and the second mode is displayed. When the mode switching button BT13 is pressed, the purchased product can be registered by the scanner unit 212 on the clerk side. The state (operation mode) in which the registration process is executed on both the clerk side and the customer side may be referred to as a double scan mode.

Further, in the full self mode, the settlement start processing such as payment to the change machine 209 cannot be performed before the product registration processing is started, but the settlement start processing is performed before the product registration processing is started. You may be able to do it. In this case, in the full self mode, it may be possible to perform all the processing of the settlement start processing such as deposit and selection of payment method by various cards, or a part of the settlement start processing, for example, deposit of money. Alternatively, only the payment method may be selected. In the full self mode, when the payment method by various cards can be selected as the settlement start process so that the settlement start process can be performed before the registration process, the registration start shown in FIG. 13 (A) is started. On the screen, buttons corresponding to various cards to be paid may be displayed, or buttons for specifying a screen for selecting a payment method may be displayed.

(Notification of operation mode)
The POS terminal 20 notifies the current operation mode. For example, the current operation mode may be displayed on the clerk side display unit 210. Specifically, a screen having an operation mode display column may be displayed on the clerk side display unit 210, and the current operation mode may be displayed in the operation mode display column on the screen. Further, a screen on which an image corresponding to each operation mode (for example, a button-like image) is arranged is displayed on the clerk side display unit 210, and an image corresponding to the current operation mode on the screen is displayed as the current operation mode. It may be displayed in a display mode different from that of the unsupported image (for example, a display mode that stands out more than the display mode of other images). The customer side display unit 205 may also display the operation mode in the same manner.

Further, the POS terminal 20 may notify the information according to the current operation mode. For example, the customer side display unit 205 may display a message according to the current operation mode. Specifically, when the current operation mode is the full self mode, for example, when waiting, the customer himself / herself registers the product (message such as "Please scan the customer"). It may be displayed on the customer side display unit 205 (for example, scroll display with large characters).

(Transition of operation mode)
Subsequently, the transition (switching) of the operation mode of the POS terminal 20 will be described. The operation mode of the POS terminal 20 shifts according to an explicit mode transition operation (mode switching operation) by a clerk. Specifically, the key operation unit 211 includes a plurality of buttons, and according to the operation of the mode switching button 211a (see FIG. 3B) arranged at the uppermost stage and the rightmost end among the plurality of buttons. The operation mode shifts.

Since the mode switching button 211a is arranged at the corner of the key operation unit 211, it is possible to reduce operation mistakes when shifting the mode and to easily shift the operation mode. That is, when the mode switching button 211a is present at the corner of the key operation unit 211, for example, the mode switching button 211a which is the operation target is compared with the case where the mode switching button 211a is located near the center of the key operation unit 211. Since the number of other adjacent buttons is small, operation mistakes such as operating other buttons in a hurry are unlikely to occur, and the position of the mode switching button 211a, which is the operation target, can be instantly specified, so the mode transition operation can be performed without stress. It can be performed.

Furthermore, since the mode switching button 211a is arranged at the upper right corner (topmost and rightmost) of the key operation unit 211, the mode transition operation is performed not only when the store clerk is on the store clerk side but also when the store clerk is on the customer side. It will be easier. That is, the clerk on the customer side cannot normally see each button of the key operation unit 211, but the mode switching button 211a existing at the upper right end of the key operation unit 211 is reached out from the customer side and groped. Since the mode switching button 211a, which is the operation target, can be easily recognized only by (feeling of the hand), the clerk on the customer side can perform the mode transition operation without moving to the clerk side. Further, since the mode switching button 211a is located at the uppermost stage and the rightmost end (outermost end) of the key operation unit 211, it is arranged at a close position when the store clerk operates from the customer side, so that the store clerk can easily operate. It becomes.

In the present embodiment, the mode switching button 211a is arranged at the upper right corner of the key operation unit 211, but if it is a position that can be recognized only by fumbling (a position that can be recognized relatively easily), the mode is used. The switching button 211a may be arranged at a position other than the upper right corner of the key operation unit 211, for example, at the lower right end. In addition, instead of or in addition to arranging the mode switching button 211a at a position that can be recognized only by groping (for example, the corner at the upper right corner), it can be distinguished from other buttons even from the customer side. The mode switching button 211a may be formed on the surface. For example, the size of the mode switching button 211a may be different from the size of other buttons to the extent that it can be distinguished only by groping, or the shape of the mode switching button 211a may be different from the shape of other buttons. Alternatively, the height of the mode switching button 211a may be different from the height of the other buttons (for example, the mode switching button 211a may be projected more than the other buttons). ), The feel of all or part of the surface of the mode switching button 211a (the surface touched by the hand) may be different from the feel of other buttons (for example, only the surface of the mode switching button 211a is rough or rough. You may feel it, or you may provide protrusions or dents only on the surface of the mode switching button 211a).

In the present embodiment, the mode switching button 211a is arranged in the key operation unit 211 in consideration of various advantages as described above, but instead of arranging the mode switching button 211a in the key operation unit 211, the mode switching button 211a is arranged. Alternatively, a mode switching button (not shown) may be arranged on the screen displayed on the clerk side display unit 210.

Subsequently, the transition (switching) of the operation mode of the POS terminal 20 will be described. The POS terminal 20 is an explicit mode transition operation by a clerk (for example, as shown in FIG. 9A, pressing the first mode switching button BT12 or the second mode switching button BT13 displayed on the clerk side display unit 210. The operation mode shifts according to the operation, the input on the operation mode setting screen, the operation of the operation mode setting button, etc.). As the button (key) used for mode switching, the key operation unit 211 is used instead of the first mode switching button BT12 shown in FIG. 9A or the like or the second mode switching button BT13 shown in FIG. 13B. It may be used as a mode switching key (hard key) set to, or these may be used in combination. As shown in FIG. 9A, the characters "switch to full self" are displayed on the first mode switching button BT12 displayed in the normal mode. Hereinafter, a transition example in which the operation mode is shifted by pressing the first mode switching button BT12 will be described.

7 and 8 are diagrams illustrating an example of transition of the operation mode. FIG. 7 is a flowchart showing the flow of transition from the normal mode to the full self mode. FIG. 8 is a flowchart showing the flow of transition from the full self mode to the normal mode. The transition from the normal mode to the full self mode and the transition from the full self mode to the normal mode are performed by, for example, the first mode switching button BT12 or the second mode switching button BT13 by a clerk or the like when the product is not registered. It is done by operation. Further, when a condition such as the start of the registration process is satisfied, the operation of the first mode switching button BT12 or the second mode switching button BT13 may prohibit the transition of the operation mode. Further, in the full self mode, when the customer side registration process or the like is not performed for a certain period of time, the registration by the customer side scanner unit 206 or the like is prohibited (for example, the usage state of the customer side scanner unit 206 being accepted). The prohibition of change of is lifted). Hereinafter, these cases will also be described.

(Transition from normal mode to full self mode)
The flowchart of FIG. 7 starts at all times (regularly at very short time intervals) in the POS terminal 20 (normal mode). Since it is in the normal mode, the clerk side scanner unit 212 is accepting, and the customer side scanner unit 206 is not accepting. When the scanner unit 212 on the clerk side is accepting, the product can be registered by pressing the display unit 210 on the clerk side. Similarly, when the clerk-side scanner unit 212 is not accepting, the product cannot be registered by pressing the clerk-side display unit 210. Similarly, when the customer side scanner unit 206 is accepting, the product can be registered by pressing the customer side display unit 205, and when the customer side scanner unit 206 is not accepting. , The product cannot be registered by pressing the customer side display unit 205. The reception at the customer side scanner unit 206 and the clerk side scanner unit 212 means reading of purchased products, etc., which can be read during reception and cannot be read during non-reception. The reception of the customer side scanner unit 206 and the store clerk side scanner unit 212 means the usage state of the customer side scanner unit 206 and the store clerk side scanner unit 212, so to speak, it is in a usable state during reception and is not being accepted. At that time, it is in an unusable state. The unreadable mode may be a mode in which the functions of the customer-side scanner unit 206 and the clerk-side scanner unit 212 themselves are stopped, or the customer-side scanner unit 206 and the clerk-side scanner unit 212 themselves are functioning, but the customer. The information read by the side scanner unit 206 and the clerk side scanner unit 212 may be processed so as not to be recognized by the CPU 201 or the like.

Further, in the flowcharts shown in FIGS. 7 and 8, the scan in the customer side scanner unit 206 and the clerk side scanner unit 212 may mean only the scan itself in the customer side scanner unit 206 and the clerk side scanner unit 212. Other product registration methods may be included. For example, the scan in the customer side scanner unit 206 includes an operation in which the customer presses the order button in order to register the product when the product order button (preset key) or the like is displayed on the customer side display unit 205. But it may be. Further, the scan in the customer side scanner unit 206 includes an operation in which the store clerk presses the order button in order to register the product when the product order button (preset key) or the like is displayed on the store clerk side display unit 210. However, when a key corresponding to the product (for example, a key corresponding to a sports newspaper) is arranged in the key operation unit 211, the clerk presses the key to register the product. It may be included. Further, when the customer side scanner unit 206 is not being accepted, the product order button (preset key) or the like may not be displayed on the customer side display unit 205, or the order button may be displayed. However, even if the operation of pressing the order button is performed, the registration may not be performed. Similarly, when the clerk side scanner unit 212 is not accepting, the clerk side display unit 210 may not display the product order button (preset key) or the like, or the order button may be displayed. However, even if the operation of pressing the order button is performed, the registration may not be performed. Further, even if the key corresponding to the product in the key operation unit 211 is pressed, the registration may not be performed.

Step S111: It is determined whether or not there has been a deposit. The deposit is made by the customer or the like inserting banknotes or coins into the change machine 209. If there is a deposit, the process proceeds to step S112, and if there is no deposit, the process proceeds to step S113.
Step S112: Deposit processing is performed. As a deposit process, the deposited amount is stored in the RAM 203, and the deposited amount is displayed on the customer side display unit 205 and the clerk side display unit 210, respectively. In addition, the settlement start process is performed by the deposit process, and the settlement process is started. Then, the process proceeds to step S113.

Step S113: It is determined whether or not the mode switching button is pressed. For example, it is determined whether or not the first mode switching button BT12 shown in FIG. 9A is pressed by a clerk or the like. When the first mode switching button BT12 is pressed, the process proceeds to step S114. If the first mode switching button BT12 is not pressed, the process proceeds to step S115.
Step S114: It is determined whether the registration of the purchased product has been started, or whether the payment has been processed and has not been settled. The registered product is registered, for example, by reading a barcode (product code or the like) provided on the product by the clerk side scanner unit 212 or the customer side scanner unit 206. Here, the customer side scanner unit 206 is accepting, but the clerk side scanner unit 212 is not accepting. When the clerk side scanner unit 212 is not accepting, the registration process is performed by the customer side scanner unit 206. If the registration of the purchased product has been started or the payment has been processed and the payment has not been made, the process proceeds to step S115. Further, in step S114, when the first mode switching button BT12 is operated, the process of shifting from the normal mode to the full self mode is performed, but after the registration process or the deposit process is performed, the first mode is performed. Even if the mode switching button BT12 is operated, the transition from the normal mode to the full self mode is prohibited, and the switching between the clerk side scanner unit 212 and the customer side scanner unit 206 is prohibited. Therefore, if the product registration has not been started and the payment process has not been performed, or if the product has been settled, the process proceeds to step S119.

Step S115: It is determined whether or not the product has been scanned by the clerk side scanner unit 212. Whether or not the product is scanned by the clerk-side scanner unit 212 is determined by whether or not the clerk-side scanner unit 212 scans the barcode attached to the purchased product. When the purchased product is scanned by the clerk side scanner unit 212, the process proceeds to step S116. If the clerk side scanner unit 212 has not scanned the purchased product, the process proceeds to step S117.
Step S116: The purchased product is registered in RAM 203. Specifically, various information such as product information in the barcode scanned by the clerk-side scanner unit 212 is stored in the RAM 203. After that, the process proceeds to step S117.

Step S117: It is determined whether or not the accounting button (subtotal key) is pressed. For example, it is determined whether or not the end (receipt) button BT40 shown in FIG. 11B has been pressed. If the accounting button is pressed, the process proceeds to step S118. If the accounting button is not pressed, the process returns to step S111.
Step S118: The settlement process is performed. After the settlement process is completed, for example, the printing unit 213 issues a receipt. Then, the flowchart of FIG. 7 ends. In addition, you may issue a receipt printed so that the product registered by the clerk side and the product registered by the customer side can be distinguished. For example, a mark such as a rice mark or a star mark, an underline, or the like may be added to either one of the products registered by the clerk side or the customer side. Further, for example, a receipt may be issued in which the print area of the product registered on the customer side and the print area of the product registered on the clerk side are separated. That is, a receipt may be issued in which the product registered on the customer side and the product registered on the clerk side are printed in different areas.

Step S119: The operation mode is changed from the normal mode to the full self mode (registration-only mode). Then, the process proceeds to step S120.
Step S120: Start accepting the customer side scanner unit. In the full self mode, the customer side scanner unit 206 registers the purchased product, so that the customer side scanner unit 206, which was not being accepted, is being accepted. Then, the process proceeds to step S121.
Step S121: Cancels the reception of the scanner unit 212 on the clerk side. In the full self mode, since the purchase product is registered by the clerk side scanner unit 212, the clerk side scanner unit 212 that was being accepted is not accepted. Then, the flowchart of FIG. 7 ends.

In this way, in the normal mode, the transition to the full self mode is permitted until the purchased product is registered or paid (in the case of the previous processing from registration to settlement, after the settlement is completed). , The usage state of the customer side scanner unit 206 and the store clerk side scanner unit 212 can be switched. In addition, after the purchased product is registered or paid, the transition to the full self mode is prohibited until the settlement is completed, and the switching of the usage status of the customer side scanner unit 206 and the clerk side scanner unit 212 is prohibited. ..

(Transition from full self mode to normal mode)
The flowchart of FIG. 8 starts at all times (regularly at very short time intervals) in the POS terminal 20 (full self mode). Since it is in the full self mode, the clerk side scanner unit 212 is not accepting, and the customer side scanner unit 206 is accepting. In addition, the forced termination button described later is not being accepted.

Step S151: It is determined whether or not there has been an operation on the customer side. The operation on the customer side includes, for example, scanning by the customer side scanner unit 206 and operation of various buttons displayed on the customer side display unit 205. If there is an operation on the customer side, the process proceeds to step S152. The timekeeping start condition for starting the timekeeping by the timekeeping timer is when the customer's operation is the last (when the customer last performs the operation). If there is no operation on the customer side, the process proceeds to step S154.

Step S152: Set the timekeeping timer. The timekeeping timer is a timer that measures the time when various devices on the customer side are not operated. A time limit is set in the timekeeping timer. The time limit is the time for shifting the operation mode to the face-to-face mode by not operating various devices on the customer side in the full self mode, and can be set to any time. For example, 2 minutes, 3 minutes, and 5 minutes. The time can be 10 minutes or the like. Further, the time may be other than these times. Further, the time limit may be arbitrarily set at a store or the like. The timekeeping timer measures the time since the last operation on the customer side scanner unit 206, the customer side display unit 205, or the like is received.
Step S153: The forced end button shown in FIGS. 14 (B) and 15 is set to the non-accepted state. Here, if the forced end button is being accepted, the forced end button is changed to non-accepting, and if the forced termination button is not being accepted, that state is maintained.

Step S154: It is determined whether or not the mode switching button is pressed. For example, it is determined whether or not the second mode switching button BT13 shown in FIG. 13B is pressed by a clerk or the like. When the second mode switching button BT13 is pressed, the process proceeds to step S155. If the second mode switching button BT13 is not pressed, the process proceeds to step S158.
Step S155: It is determined whether or not the purchased product has been registered and has not been settled. If it is after the registration of the purchased product is started and before the settlement, the process proceeds to step S156. Further, in step S155, when the second mode switching button BT13 is operated, the process of shifting from the full self mode to the normal mode is performed, but after the registration process is performed, the second mode is switched. Even if the button BT13 is operated, the transition from the full self mode to the normal mode is prohibited. In this way, when there is a registration process or the like, switching of the usage state of the clerk side scanner unit 212 and the customer side scanner unit 206 is prohibited. Therefore, if the product registration has not been started, the process proceeds to step 167.

Step S156: It is determined whether or not the clerk side scanner unit 212 is accepting. The clerk-side scanner unit 212 is not being accepted at the start of the flowchart shown in FIG. 8, but may be switched during acceptance in a later process. If the clerk side scanner unit 212 is not accepting, the process proceeds to step S157. If the clerk side scanner unit 212 is accepting, the process proceeds to step S158.
Step S157: Start accepting the scanner unit 212 on the clerk side. Specifically, the clerk side scanner unit 212 is switched from non-reception to reception. By switching the scanner unit 212 on the clerk side during reception, the mode shifts to the double scan mode in which both the scanner unit 206 on the customer side and the scanner unit 212 on the clerk side can register the purchased product. In the normal mode, when the registration process is started, even if the second mode switching button BT13 is operated, it is prohibited to switch the customer side scanner unit 206 during reception in step S114 of FIG. 7. In the full self mode, when the second mode switching button BT13 is operated after the registration is started, the prohibition of switching from the non-reception to the reception of the clerk side scanner unit 212 is released, and the clerk side scanner unit 212 is released. Starts reception. After that, the process proceeds to step S155.

Step S158: It is determined whether or not the product is scanned by the customer side scanner unit 206. Whether or not the product is scanned by the customer-side scanner unit 206 is determined by whether or not the bar code attached to the purchased product is scanned by the customer-side scanner unit 206. If the purchased product is scanned by the customer-side scanner unit 206, the process proceeds to step S159. If the purchased product is not scanned by the customer-side scanner unit 206, the process proceeds to step S161.
Step S159: It is determined whether or not the clerk side scanner unit 212 is accepting. If the clerk side scanner unit 212 is accepting, the process proceeds to step S160. If the clerk side scanner unit 212 is not accepting, the process proceeds to step S163.

Step S160: It is determined whether or not the product has been scanned by the clerk side scanner unit 212. When the purchased product is scanned by the clerk side scanner unit 212, the process proceeds to step S161. If the clerk side scanner unit 212 has not scanned the purchased product, the process proceeds to step S163.

Step S161: The purchased product is registered in the RAM 203. Specifically, various information such as product information in the barcode scanned by the clerk side scanner unit 212 or the customer side scanner unit 206 is stored in the RAM 203.
Step S162: It is determined whether or not the accounting button is pressed. For example, it is determined whether or not the accounting button (the end (receipt) button BT40 shown in FIG. 14A) has been pressed. If the accounting button is pressed, the process proceeds to step S170. If the accounting button is not pressed, the process returns to step S151.

Step S163: It is determined whether or not the time limit has elapsed. Specifically, it is determined in step S152 whether or not the time set in the timekeeping timer has elapsed. If the time limit has elapsed, the process proceeds to step S164. If the time limit has not elapsed, the process proceeds to step S162.
Step S164: Start accepting the forced end button. For example, as shown in FIG. 15, below the clerk side display unit 210 in the full self mode, there is a forced end button BT14 for forcibly ending the full self mode and shifting to the normal mode, and a double scan mode from the full self mode. The clerk participation button BT15 to switch is displayed. The forced end button BT14 and the clerk participation button BT15 are displayed side by side at the lower center position of the clerk side display unit 210. When the forced end button BT14 starts accepting, the full self mode is forcibly terminated and the mode shifts to the normal mode when the store clerk or the like presses and operates the forced end button BT14. Before the reception of the forced end button is started, the forced end button BT14 is grayed out and displayed as shown in FIG. 14 (B). At this time, instead of displaying the forced end button BT14 in gray, the forced end button BT14 may not be displayed. When the forced termination button BT14 is pressed, the registration is forcibly terminated and the registration by the operation of the customer side scanner unit 206 becomes impossible. Therefore, by starting the reception of the forced end button, the switching from the reception to the non-reception of the customer side scanner unit 206 is canceled.
Step S165: It is determined whether or not the forced end button is pressed. Specifically, it is determined whether or not the forced end button BT14 shown in FIG. 15 is pressed and operated by a store clerk or the like. If the forced termination button is pressed, the process proceeds to step S166. If the forced termination button is not pressed, the process proceeds to step S162.
Step S166: Exit the full self mode. After exiting the full self mode, the mode shifts to the normal mode. When the forced termination is performed, the registration information, etc. for the registered and unpaid products is destroyed (erased). Then, the flowchart of FIG. 8 ends. After the forced termination, the full self mode may be left, the operation mode may be changed to the operation mode other than the normal mode, or the operation mode to be changed may be specified. In addition, it is not necessary to destroy the registration information after the forced termination.

Step S167: The operation mode is changed from the full self mode (registration-only mode) to the normal mode.
Step S168: Start accepting the scanner unit on the clerk side. In the normal mode, since the purchase product is registered by the clerk side scanner unit 212, the clerk side scanner unit 212, which has not been accepted, is being accepted.
Step S169: The reception of the customer side scanner unit 206 is canceled. In the normal mode, the scanner unit 212 on the clerk side registers the purchased product, so that the scanner unit 206 on the customer side, which was being accepted, is not being accepted. Then, the flowchart of FIG. 8 ends.
Step S170: The settlement process is performed. After the settlement process is completed, for example, the printing unit 213 issues a receipt. Then, the flowchart of FIG. 8 ends.

As described above, in the full self mode, the transition to the normal mode is permitted until the purchased product is registered or the payment is made, and the usage state of the customer side scanner unit 206 and the clerk side scanner unit 212 can be switched. In addition, after the purchased product is registered or deposited, the transition to the full self mode is prohibited until the settlement is completed, but instead, the transition to the double scan mode is performed. For this reason, switching between the usage status of the customer side scanner unit 206 and the clerk side scanner unit 212 is prohibited until the settlement is completed after the purchased product is registered or paid, but the clerk side scanner unit 212 Is lifted.

Further, when the full self mode is started, the customer registers the product, so that the switching of the usage state of the scanner unit 206 on the customer side is prohibited, but a long time elapses without any operation on the customer side. Then, it is conceivable that the customer canceled the registration by the customer side scanner unit 206 in the middle before the settlement was completed. Therefore, when the time limit elapses without any operation on the customer side, the prohibition of switching the usage state of the customer side scanner unit 206 is released, and the full self mode is shifted to the normal mode to shift to the customer side scanner unit. 206 is not accepted.

In the full self mode, if the deposit process is possible before the registration process is started as in the normal mode, the timing at which the second mode switching button BT13 is pressed in step S152 is after the registration is started. Instead of the judgment that the full self mode is changed to the normal mode when it is not before the settlement, the full self mode is changed to the normal mode when the timing when the second mode switching button BT13 is pressed is not before the settlement is started or after the payment is made. You may try to do it. Further, in the steps shown in FIGS. 7 and 8, an example in which the settlement start process is a deposit to the change machine 209 has been described, but when there is a deposit in the change machine 209 when another settlement start process is performed. You may perform the same processing as above.

(Display in normal mode)
Subsequently, the display in the normal mode will be described with reference to FIGS. 9 to 12. 9 to 12 are display examples of the clerk side display unit 210 and the customer side display unit 205 in the normal mode. FIG. 9A is a display example of the registration screen displayed on the clerk side display unit 210 of the POS terminal 20, and is a display example of the registration start screen before the purchase of the product is performed. In the screen shown in FIG. 9A, a subtotal button BT10, a pause button BT11, and a first mode switching button BT12 are displayed at the lower right of the screen. The subtotal button BT10 is a button (registration completion key) for instructing the end of product registration. The clerk operates (touches) the subtotal button BT10 after the product registration is completed. The pause button BT11 is a button for suspending the POS terminal 20. The clerk operates the pause button BT11 when he / she leaves the POS terminal 20 (for example, when he / she goes to search for a product or when he / she does not use the POS terminal 20 for a while). The first mode switching button BT12 is a button for switching modes. The clerk operates the first mode switching button BT12 when switching modes. The characters "Switch to full self" are displayed on the first mode switching button BT12. The first mode switching button BT12 is grayed out and displayed when the mode switching is prohibited and the operation of the button is not valid. In addition, instead of the gray-down display, the display may not be performed. Further, since it is unlikely that the subtotal button BT10 will be operated until the product is registered, the subtotal button BT10 may not be displayed on the registration start screen. In this case, for example, the subtotal button BT10 may be displayed when the product is registered at the beginning of the transaction.

FIG. 9B is a display example of the screen displayed on the customer side display unit 205 of the POS terminal 20 and is a display example before the product is purchased. In the screen shown in FIG. 9B, the clerk call button BT33 is displayed on the lower left side, and the display language switching buttons BT35 to B37 are displayed on the right side. The clerk call button BT33 is a button for calling a clerk. The customer operates the clerk call button BT33 when calling the clerk (for example, when the clerk's support is required). The display language switching buttons BT35 to BT37 are buttons for switching the display language to English, Chinese, and Korean, respectively. On the display language switching buttons BT35 to BT37, the national flag of each country and the characters indicating the language are displayed in each language.

The message "You can put money at any time" is displayed in the message display section at the bottom of the screen, and an image imitating the state of putting money into the change machine 209 is displayed in the center of the screen. When money is inserted into the change machine 209, among the screens shown in FIG. 10B, the screen showing the information about the registered product and the score and amount of the registered product accompanying the registration of the product is not displayed on the customer side. It is displayed in the unit 205.

FIG. 10A is a display example of the registration screen displayed on the clerk side display unit 210 of the POS terminal 20, and is a display example during the registration of the product. Specifically, FIG. 10A is a screen showing the display contents of the registration screen in the scene where one item of product (canned beer) and two items of product (asparagus) are registered. In the screen shown in FIG. 10A, the product name (asparagus) of the currently registered product and the product name (canned beer, asparagus) of the registered product are displayed at the upper left of the screen together with the respective amounts. In addition, the points and total amount of registered products are displayed in the upper right corner of the screen. When the product registration is started, the operation mode switching is prohibited, so the first mode switching button BT12 is grayed out and displayed. The broken line of the first mode switching button BT12 indicates that the operation of the button (first mode switching button BT12) is displayed in a display mode (grayed down here) indicating that the operation is not valid. Further, the display may not be performed instead of the gray-down display.

FIG. 10B is a display example of the screen displayed on the customer side display unit 205 of the POS terminal 20, and is a display example during the registration of the product, which is shown in FIG. 10A. This is the screen displayed on the customer side display unit 205 when the image is displayed on the store clerk side display unit 210. On the screen shown in FIG. 10B, the product name of the registered product (canned beer, asparagus) is displayed at the top, and the product name (asparagus) of the currently registered product is displayed at the lower left side together with the registered points and the amount of money. ing. Below that, the number of registered products, the total amount, and the deposit amount are displayed. The deposit amount is the amount of money that has already been inserted from the change machine 209. Further, on the screen shown in FIG. 10B, the clerk call button BT33 is displayed on the right side, and the display language switching buttons BT35 to B37 are displayed on the lower side. The functions of the clerk call button BT33 and the display language switching buttons BT35 to B37 are the same as those of the buttons shown in FIG. 9B.

FIG. 11A is a display example of the screen displayed on the clerk side display unit 210 of the POS terminal 20, and is a display example during the settlement. Specifically, FIG. 10A shows that when the registration screen is displayed, the total amount is "total" on the screen in which the product is last registered, and for the change machine 209. This is the screen where the deposit amount is displayed as "fishing machine deposit amount". In the example shown in FIG. 11A, "383 yen" is displayed as the total amount and "1,000 yen" is displayed as the fishing machine entry amount.

Further, a deposit cancellation button BT18 is provided at the lower right of the deposit amount of the change machine. The deposit cancellation button BT18 is a button for canceling the deposit to the change machine 209. The clerk who received the request for cancellation of payment cancels the payment by pressing the payment cancellation button BT18. When the deposit is canceled, the change machine 209 will refund the money equivalent to the deposit amount to the customer. The money to be refunded may be the money itself put in by the customer or the money of the same amount as the money put in by the customer. The deposit cancellation button BT18 is displayed on the clerk side display unit 210 and is not displayed on the customer side display unit 205. Therefore, when the customer cannot perform the operation of canceling the deposit and wants to return the deposited money, he / she will ask the clerk. The deposit cancellation button BT18 may be displayed not only on the clerk side display unit 210 but also on the customer side display unit 205, or may be displayed only on the customer side display unit 205.

When the screen shown in FIG. 11A is displayed, switching of the operation mode (switching from the normal mode to the full self mode) is prohibited, so that the first mode switching button BT12 shown in FIG. 9A is prohibited. Is not displayed. On the other hand, the grayed-down first mode switching button BT12 may be displayed.

FIG. 11B is a display example on the settlement screen displayed on the customer side display unit 205 of the POS terminal 20. Specifically, on the screen shown in FIG. 11B, the message "Please press the end button if you like" is displayed, and the payment amount (here, "383 yen") and the deposit amount (in this case, "383 yen") are displayed. Here, "1,000 yen") and change (here, "617 yen") are displayed. The payment amount is the total amount of the registered products. The deposit amount is the total amount of money that the customer or the like put into the change machine 209. The change is the amount of deposit minus the payment amount. The end (receipt) button BT40 is displayed at the bottom of the column where the change is displayed. The end (receipt) button BT40 is displayed when the deposit amount exceeds the payment amount. When the end (receipt) button BT40 is pressed, the deposit amount and the payment amount are confirmed and the payment is executed, and the change (here, "617 yen") is discharged from the change machine 209.

FIG. 12A is a settlement screen (change screen) displayed when the change is released. For example, the POS terminal 20 displays a change screen as shown in FIG. 12A when the end (receipt) button BT40 is operated. By displaying the change screen shown in FIG. 12 (A), the customer is urged to remove the change. FIG. 12B is a settlement screen (receipt screen) displayed when the change is removed. For example, in the POS terminal 20, when the change is removed from the outlet of the change machine 209, the receipt screen as shown in FIG. 12B is displayed, and the printing unit 213 issues a receipt or the like. The POS terminal 20 may install a sensor such as a photo sensor in the vicinity of the take-out port, and when the sensor recognizes an object (assuming a customer's hand), it may be determined that the change has been removed.

(Display during full self mode)
Subsequently, the display in the full self mode will be described with reference to FIGS. 13 to 15 and the like. 13 and 14 are display examples of the customer side display unit 205 and the clerk side display unit 210 in the full self mode, and FIG. 15 is a display example of the clerk side display unit 210 in the full self mode. FIG. 13A is a display example of the registration start screen displayed on the customer side display unit 205 of the POS terminal 20 before the start of product registration. In the screen shown in FIG. 13A, the registration start button BT30 is displayed on the right side of the screen, and the display language switching buttons BT35 to BT37 are displayed on the lower left side of the screen. The registration start button BT30 is a button for instructing the start of product registration. The customer operates the registration start button BT30 before starting the product registration.

In the screen shown in FIG. 13 (B), in addition to the screen shown in FIG. 13 (A), the second mode switching button BT13 is displayed. On the screen shown in FIG. 13B, the registration start button BT30 and the display language switching buttons BT35 to BT37 are displayed, but these buttons are inoperable. Inoperability means that the button does not respond even if it is pressed, or that the button responds when pressed, but the predetermined function is not exhibited even if the button responds. For example, when the registration start button BT30 displayed on the clerk side display unit 210 is pressed, the registration start button BT30 does not respond, or even if it responds, the product registration is not started.

On the second mode switching button BT13, the characters "switch to face-to-face self" are displayed. The second mode switching button BT13 has a function of switching the operation mode, similarly to the first mode switching button BT12 displayed in FIG. 9A and the like. When the clerk presses the second mode switching button BT13 before the product registration is started, the operation mode shifts from the full self mode to the normal mode. When the mode switching is prohibited and the operation of the button is not valid, the second mode switching button BT13 is not displayed. At this time, the second mode switching button BT13 may be grayed out and displayed.

FIG. 14A is a display example of the registration screen displayed on the customer side display unit 205 of the POS terminal 20 before the product registration is started. Specifically, FIG. 14A shows the display contents of the registration screen in the scene where two products (Daifuku rice cake) are registered. When the registration start button BT30 is operated on the registration start screen shown in FIG. 13 (A), the registration screen (initial state registration screen) in which no product has been registered is displayed. For convenience of explanation, FIG. 14A shows a registration screen after the product has already been registered.

As shown in FIG. 14A, the message "Please register the product" is displayed in the upper left of the screen, and the message "Please bring the barcode of the product closer to the scanner to register" is displayed below it. Is displayed. Further below, the message "If there is no barcode, please select an item from the bottom" is displayed, and below that, the "Vegetable" button BT38 is displayed.

The end (receipt) button BT40 is displayed at the lower right of the screen, and the clerk call button BT33 is provided on the left side thereof. The end (receipt) button BT40 is a button for instructing the end of product registration. The customer operates the end (receipt) button BT40 after the product registration is completed. The clerk call button BT33 is a button for calling a clerk as described above.

Further, the display language switching buttons BT35 to BT37 are displayed at the lower left of the screen. Further, the "vegetable" button BT38 is a button for displaying each preset key of the vegetable. By pressing the "vegetable" button BT38, preset keys corresponding to vegetable products (for example, carrots, Chinese cabbage, cabbage, onions, etc.) are displayed.

FIG. 14B is a display example of the registration screen displayed on the clerk side display unit 210 of the POS terminal 20 after the product registration is started. In the screen shown in FIG. 14B, in addition to the screen shown in FIG. 14A, the second mode switching button BT13 is displayed. The registration start button BT30 and the display language switching buttons BT35 to BT37 displayed on this screen are inoperable like the registration start button BT30 and the display language switching buttons BT35 to BT37 shown in FIG. 13 (B). Further, when the store clerk presses the second mode switching button BT13 after the product registration is started, the mode shifts from the full self mode to the double scan mode. Therefore, the characters "participate in registration" are displayed on the second mode switching button BT13. That is, it means that the store clerk shifts to the double scan mode in which the customer participates in the registration where the customer is registering the product in the full self mode. Regarding the second mode switching button BT13, "Switch to face-to-face self" is displayed to switch from the full self mode to the normal mode before the registration or the settlement is started, and after the registration or the settlement is started, the full self is displayed. "Join registration" is displayed to switch from the mode to the double scan mode. On the other hand, a mode switching button for switching from the full self mode to the normal mode and a mode switching button for switching from the full self mode to the double scan mode may be provided separately. In this case, these mode switching buttons are arranged at different positions on the clerk side display unit 210. Further, when these mode switching buttons are not being accepted, they may be grayed out or may not be displayed.

The screen shown in FIG. 14B is a display example before the reception of the forced end button is started. Therefore, since the reception of the forced end button has not started, the forced end button BT14 is grayed out and displayed. At this time, the forced termination button BT14 may not be displayed.

FIG. 15 is a display example of the screen displayed on the clerk side display unit 210 of the POS terminal 20, and is a display example after the customer has started registering the product and before the reception of the forced end button is started. .. On the screen shown in FIG. 15, the forced termination button BT14, which was grayed out in FIG. 14B, is displayed and can be pressed. By pressing the forced end button BT14 while the forced end button BT14 is displayed, the full self mode is forcibly terminated and the operation mode shifts to the normal mode.

(Display in double scan mode)
When shifting from the full self mode to the double scan mode, the screen displayed on the customer side display unit 205 is the same as the screen displayed in the full self mode, but as a registered product, the customer is the customer. In addition to the products registered in the side scanner unit 206, the products registered by the clerk in the clerk side scanner unit 212 are also included. At this time, the product registered by the clerk side scanner unit 212 is displayed in a display mode different from the product registered by the customer side scanner unit 206. The different display mode is, for example, a mode in which the font is changed or the background color is different.

Further, the display unit 210 on the clerk side is the same as the screen displayed in the normal mode, but the products to be registered include the products registered by the clerk on the scanner unit 212 on the clerk side and the customer side. Products registered in the scanner unit 206 are also included. Further, at the time of payment, both the customer side display unit 205 and the clerk side display unit 210 are the same as the screen displayed in the normal mode. At this time, the product registered by the customer-side scanner unit 206 is displayed in a display mode different from that of the product registered by the store clerk-side scanner unit 212.

When the end (receipt) button BT40 is pressed, a change screen as shown in FIG. 12 (A) is displayed. By displaying the change screen shown in FIG. 12 (A), the customer is urged to remove the change. FIG. 12B is a settlement screen (receipt screen) displayed when the change is removed. For example, the POS terminal 20 displays a receipt screen as shown in FIG. 12B when change is removed from the outlet of the change machine 209. The POS terminal 20 may install a sensor such as a photo sensor in the vicinity of the take-out port, and when the sensor recognizes an object (assuming a customer's hand), it may be determined that the change has been removed.

For example, in the normal mode or the full self mode, it is unlikely that the purchase product will be switched to the full self mode or the normal mode after the registration of the purchased product is started. It is highly probable that the operation of switching the operation mode in such a situation is not an intentional operation but an erroneous operation. In this regard, according to the above-mentioned POS terminal 20, after the registration of the purchased product is started, the mode switching is prohibited, and specifically, the switching from the normal mode to the full self mode and the switching from the full self mode to the normal mode are prohibited. Switching to is prohibited. Therefore, it is possible to prevent unintended switching of the operation mode.

Further, for example, if the operation mode is switched between the normal mode and the full self mode after the registration of the purchased product is started, it may be necessary to restart the registration of the purchased product from the beginning. In this case, the number of times the purchased product is registered increases, the operation of the cash register is reduced, it takes time to settle the product, and the customer may be kept waiting.

In this regard, in the above-mentioned POS terminal 20, since the mode switching is prohibited after the registration of the purchased product is started, the usage state of the scanner unit 212 on the clerk side is switched (switching between accepting and non-accepting). Is prohibited. Therefore, it is possible to prevent the re-registration of the purchased product from occurring, and the product can be settled smoothly. As a result, it is possible to suppress the decrease in the operation of the cash register, and it is possible to prevent the customer from waiting.

Further, in the case of the full self mode, if the customer is not accustomed to registering the product and it takes longer to register the product compared to other customers, it is assumed that a plurality of POS terminals 20 are provided. However, the time required for processing from registration to settlement on the POS terminal 20 becomes long, and there is a concern that the operation of the POS system 1 as a whole may deteriorate. In this respect, in the above-mentioned POS terminal 20, when the customer is registering in the full self mode, the prohibition of switching the operation mode and the prohibition of switching the usage state of the scanner unit 212 on the clerk side are released. By operating the second mode switching button BT13, the operation mode is switched from the full self mode to the double scan mode, the clerk side scanner unit 212 is switched from non-reception to reception, and the reception of the clerk side scanner unit 212 is started. can do. Therefore, the registration time in the POS terminal 20 can be shortened, and the time required from registration to settlement can be equal to or longer than that of the other POS terminals 20. Therefore, since it is possible to suppress a decrease in the operation of the cash register, it is possible to prevent the customer from waiting.

Further, when the operation for the customer side in the POS terminal 20 is not executed during the full self mode, it is assumed that there is no customer in the vicinity of the POS terminal 20. It is conceivable that the reason why there is no customer in the vicinity of the POS terminal 20 is that the customer interrupts (cancels) the registration of the product on the way and leaves it as it is. When there is no customer near the POS terminal 20, the POS terminal 20 cannot be used in the full self mode, which causes a decrease in the operation of the POS terminal 20. In this regard, in the POS terminal 20, when a predetermined time limit has elapsed since the last operation of the customer such as a scan on the customer side scanner unit 206 or an operation on the customer side display unit 205 has passed during the full self mode, in other words. For example, when the operation on the customer side has not been performed beyond the time limit, the POS terminal 20 is forcibly terminated and returned to the full self mode by operating the forced termination button BT14 displayed on the clerk side display unit 210. I am doing it. Therefore, even when a customer registers on the POS terminal 20 in the full self mode and the product registration is interrupted and left unattended, the POS terminal 20 can be opened to other customers. Therefore, it is possible to suppress a decrease in the operation of the POS terminal 20.

Further, as a situation where there is no customer in the vicinity of the POS terminal 20, it is assumed that the customer who has started the registration remembers the product that he / she forgot to buy and fetches it from the sales floor. In this case, the customer interrupted the registration of the product, but intends to resume it. Even in this case, if the POS terminal 20 is forcibly terminated, it may take time and effort to re-register the same product. In this regard, since the POS terminal 20 has a time limit before the forced termination, even if there is no customer in the vicinity of the POS terminal 20, the POS terminal 20 is not immediately forcibly terminated, so that the registration is re-registered. You can save time and effort. Assuming that the customer who started the registration remembers the product that he / she forgot to buy and fetches it from the sales floor, it is preferable that the time limit is, for example, about 5 minutes. Alternatively, the time limit may be set based on the size of the sales floor, past information, and the like. Furthermore, the time limit may be set based on information such as the date (day of the week).

Further, the forced termination of the POS terminal 20 is performed based on the operation of pressing the forced termination button BT14 displayed on the clerk side display unit 210. Therefore, since it is possible to prevent the customer from forcibly terminating, it is possible to avoid troubles between the customers. In addition, when the clerk is aware of the circumstances in which the customer leaves the POS terminal 20, the forced termination is not performed even if the time limit is significantly exceeded, so registration is started due to the forced termination. It is possible to reduce the discomfort given to the customer.

Further, when the POS terminal 20 is forcibly terminated, the registration information of the product registered by the customer side display unit 205 or the customer side scanner unit 206 is destroyed. Therefore, for example, when the customer leaves the POS terminal 20 and the forced termination is reached, the burden on the settlement process can be reduced. The registration information may be put on hold without being destroyed.

Although the embodiments of the present invention have been described above, the configuration of the device, the configuration of the data, the flow of processing, the mode of display and output, and the like can be appropriately changed and modified.

(About error display)
In the above POS terminal 20, when the transition of the operation mode is prohibited, for example, in the normal mode or the full self mode, the first mode switching button BT12 or the second mode switching button BT13 is operated after the registration is started and before the settlement. At that time, the operation mode as it is continues without shifting to the full self mode or the normal mode. At this time, even if the first mode switching button BT12 or the second mode switching button BT13 is operated, the operation of the first mode switching button BT12 or the second mode switching button BT13 on the clerk side display unit 210 or the customer side display unit 205. However, an error display based on the operation of the first mode switching button BT12 or the second mode switching button BT13 may be performed. By displaying such an error, it is possible to make it easier for the store clerk to recognize the prohibition of switching the operation mode.

For example, if the first mode switching button BT12 is operated after the start of registration and before the settlement when the operation mode is the normal mode, the display based on the operation of the first mode switching button BT12 is shown in FIG. 16 (A). As such, the error screen may be displayed during the normal mode. The error screen in the normal mode is a screen in which the error display GA50 in the normal mode is displayed on the screen displayed on the clerk side display unit 210 in the normal mode. Error display in normal mode GA50 displays the message "Error product registration (payment) is in progress. Do you want to switch to full self and leave the product registration?" And the text "Leave it to me". The acceptance button BT51 with the characters "No" and the rejection button BT52 with the characters "No" are displayed.

Of these, when the clerk presses the acceptance button BT51, the operation mode shifts from the normal mode to the full self mode. When the mode shifts to the full self mode, the registration screen shown in FIG. 14A is displayed on the customer side display unit 205. Further, the mirror screen shown in FIG. 14B is displayed on the clerk side display unit 210. For this reason, in principle, the transition from the normal mode to the full self mode is prohibited after the start of registration and before the settlement, but when there is an operation mode transition request (pressing the acceptance button BT51) by a clerk or the like, it is normal. It is possible to switch from mode to full self mode. When shifting from the normal mode to the full self mode, the clerk may be performing the product registration process during the normal mode. In this case, the information of the registration process is taken over as it is in the full self mode. Therefore, duplication of registration processing can be suppressed and the burden can be reduced, so that settlement can be performed smoothly. Further, when the clerk presses the refusal button BT52, the error display GA50 in the normal mode is erased while the operation mode remains the normal mode.

Further, when the second mode switching button BT13 is operated after the registration is started and before the settlement when the operation mode is the full self mode, the display based on the operation of the second mode switching button BT13 is shown in FIG. 16 (B). As shown, the error screen may be displayed during full self mode. The full self mode error screen is a screen in which the full self mode error display GA60 is displayed on the screen displayed on the clerk side display unit 210 during the full self mode. Error display in full self mode GA60 displays the message "Error customer is in use. Do you want to switch to face-to-face self and take over the product registration?" And the text "take over" is written. The acceptance button BT61 and the rejection button BT62 with the characters "No" are displayed.

Of these, when the clerk presses the acceptance button BT61, the operation mode shifts from the full self mode to the normal mode. When the mode shifts to the normal mode, the registration screen shown in FIG. 10A is displayed on the clerk side display unit 210. Further, the screen shown in FIG. 10B is displayed on the customer side display unit 205. For this reason, in principle, the transition from the full self mode to the normal mode is prohibited after the start of registration and before the settlement, but when there is an operation mode transition request (pressing the acceptance button BT61) by a clerk or the like, it is full. It is possible to shift from self mode to normal mode. When shifting from the full self mode to the normal mode, the customer may be performing the product registration process when the full self mode is used. In this case, the information of the registration process is inherited as it is in the normal mode. Therefore, duplication of registration processing can be suppressed and the burden can be reduced, so that settlement can be performed smoothly. Further, when the clerk presses the refusal button BT62, the error display GA60 in the full self mode is erased while the operation mode remains the full self mode.

Further, if the operation mode is the full self mode and the forced end button BT14 is operated before the reception of the forced end button BT14 shown in FIG. 15 is started, the display based on the operation of the forced end button BT14 is shown in FIG. As shown in, the error screen before the forced termination may be displayed. The pre-forced termination error screen is a screen in which the pre-forced termination error display GA70 is displayed on the screen displayed on the clerk side display unit 210 during the full self mode. Error display before forced termination GA70 displays the message "Error product registration (payment) is in progress. The mode cannot be switched." And the cancel button BT71 with the characters "Erase" is displayed. Is displayed. By pressing the cancel button BT71, the error display GA70 before the forced termination is erased while the operation mode remains the full self mode.

In addition, when there is an operation mode transition request (pressing the acceptance button BT51) by the clerk or the like shown in FIG. 16A, and the clerk is performing the product registration process when shifting from the normal mode to the full self mode, it is normal. The registration information registered in the mode may not be carried over to the full self mode. Similarly, when there is an operation mode request (pressing the acceptance button BT61) by a clerk or the like shown in FIG. 16B, and the customer is performing product registration processing when shifting from the full self mode to the normal mode, The registration information registered in the full self mode may not be transferred to the normal mode. In these cases, instead of not being able to take over the registration information registered in the normal mode or the full self mode before switching, for example, this registration information may be discarded or held. If the registration information is destroyed, it is possible to avoid confusion in the subsequent processing. In addition, when the registration information is withheld, the subsequent settlement process can be smoothly performed.

For example, when the acceptance button BT61 shown in FIG. 16B is pressed, the operation mode shifts from the full self mode to the normal mode. At this time, the display unit 210 on the clerk side is shown in FIG. 18A. The registration information processing selection screen is displayed. The registration information selection screen is a screen in which the registration information processing selection display GA80 is displayed on the screen displayed on the clerk side display unit 210 in the full self mode. On the registered information processing selection display GA80, the message "Move to face-to-face self. There is registered data. Do you want to discard / hold it?" Is displayed and the characters "Discard" are written. The discard button BT81 and the hold button BT82 with the characters "hold" are displayed.

When the clerk presses the discard button BT81, the registration information registered in the full self mode is discarded, and the registration start screen of the normal mode shown in FIG. 9A is displayed on the clerk side display unit 210. Further, when the hold button BT82 is pressed, the registration start screen of the normal mode shown in FIG. 18B is displayed on the clerk side display unit 210. On the registration start screen shown in FIG. 18B, the first hold display tab TAB91 and the second hold display button BT92 regarding the held registration information are displayed. By pressing the first hold display tab TAB91 and the second hold display button BT92, an image including the held registration information, the amount information, etc. is displayed, and the transaction including the held registration information is resumed. Can be done.

When holding the registration information, only one of the first hold display tab TAB91 and the second hold display button BT92 may be displayed, or the hold display button and the like may be displayed in other modes. Alternatively, the registration information (transaction information) that can be called in the form of a hold receipt may be printed as code information such as a barcode. Further, when resuming the transaction, it may be resumed in the hold mode (here, full self mode) or in the current mode (here, normal mode). Alternatively, the operation mode at the time of restart may be selectable.

(About the timing start condition)
In the above example, the timekeeping start condition is the timekeeping start condition for starting the timekeeping by the timekeeping timer when the customer's operation is the last (when the customer last performs the operation), but the timekeeping start condition may be another condition. .. For example, it may be when the customer leaves the POS terminal 20. In order to determine when the customer leaves the POS terminal 20, for example, a motion sensor that detects a person at the POS terminal 20 as a customer is provided, and when the motion sensor cannot identify the person (customer). It may be determined that the customer has left.

(Registration of customer image)
Further, the POS terminal 20 may be provided with an image pickup means (camera) for photographing the customer side, and may capture an image (customer image) such as a customer's face. The customer image is, for example, captured at the start of a transaction and stored in the RAM 203 or the like in association with the transaction code (automatic numbering) assigned to each transaction, or the face image data or the like is stored in the store controller 10. It may be sent to the store controller 10 and stored in the store controller 10.

Further, when the registration information is destroyed or put on hold, the customer image may be acquired. The customer image to be acquired may be, for example, a customer image stored in the RAM 203 of the POS terminal 20, a customer image stored in the store controller 10, or a customer image number (code) associated with these customer images. good. By acquiring the customer image, it is possible to easily identify the customer who has registered the registered information that has been destroyed or saved.

Further, a specific means for identifying the customer may be provided in place of the photographing means or together with the photographing means. As the specific means, for example, a recorder that records the voice of the customer, or a device that stores the fingerprint or vein of the customer and uses it to identify the customer may be used. Alternatively, when the customer owns a membership card or the like and possesses an ID number or the like assigned to each customer, the ID number or the like may be stored and used to identify the customer. By these specific means, it is possible to easily identify the customer who has registered the registered information that has been destroyed or saved.

(About operation mode)
The POS terminal 20 has a first mode switching button BT12 or a second mode switching button BT13 until the purchased product is registered or paid (after the settlement is completed if there was a process from registration to settlement last time). Is pressed to switch from normal mode to full self mode and full self mode to normal mode, and pressing the second mode switching button BT13 in full self mode shifts from full self mode to double scan mode. However, it may be migrated under other conditions. For example, the POS terminal 20 may shift the operation mode according to an operation other than the explicit mode shift operation by the clerk (for example, reading the clerk code). For example, in the full self mode, instead of pressing the second mode switching button BT13 or pressing the second mode switching button BT13, the POS terminal 20 is made to read the clerk code before the settlement after the registration of the purchased product. Therefore, the mode may be changed from the full self mode to the double scan mode.

Further, the POS terminal 20 has predetermined conditions (conditions related to time such as elapsed time and predetermined time (schedule), conditions related to transmission / reception of information such as commands to and from other terminals, etc." that do not depend on the operation of the clerk. ) May be used or the operation mode may be changed. Specifically, for example, the POS terminal 20 in the normal mode is not used until the purchased product is registered or paid (in the case where the processing from registration to settlement was performed last time, after the settlement is completed). If the state of is continued, the mode may be changed to the full self mode.

When operating in the full self mode, a screen in which buttons corresponding to each clerk are arranged may be displayed on the clerk side display unit 210, and the clerk may be specified according to the button touched on the screen. .. Further, instead of the operation of pressing the second mode switching button BT13 displayed on the clerk side display unit 210, the operation mode may be changed by operating the key operation unit 211. A button corresponding to each clerk may be arranged in the key operation unit 211, and the clerk may be specified according to the button operated in the key operation unit 211.

(About semi-self mode)
The POS terminal 20 is used independently to register and settle products on the POS terminal, but a POS system in which a plurality of POS terminals 20 are connected by a LAN or the like is used, and registration and settlement are performed on different POS terminals 20. You may. For example, the product registered in the first POS terminal 20-1 may be settled in the second POS terminal 20-2. The POS terminal 20 for settlement includes a normal mode, a full self mode, and a double scan mode as operation modes, as well as a semi-self mode (accounting-only mode) in which only settlement is performed without registering products. As a mode of operating the POS terminal 20 as the semi-self mode, for example, in two or more POS terminals 20, some POS terminals 20 are operated in the normal mode (registration-only mode), and the other POS terminals 20 are operated in the semi-self mode. There is a mode of operating in (payment-only mode). Hereinafter, among the first POS terminal 20-1 and the second POS terminal 20-2 shown in FIG. 1, the first POS terminal 20-1 set to the registration-only mode is set to the registration-only first POS terminal 20-1, and the second POS set to the semi-self mode. The semi-self mode will be described with the terminal 20-2 as the second POS terminal 20-2 dedicated to accounting.

When the second POS terminal 20-2 is set to the accounting-only second POS terminal 20-2 as the semi-self mode, the clerk registers the customer's purchased product on the registration-only first POS terminal 20-1. When the registration process by the clerk is completed, the customer moves to the second POS terminal 20-2 dedicated to accounting, confirms the total amount of the purchased products on the display unit 210 on the clerk side, and inserts money into the change machine 209, or a card. Operate the settlement unit 208 to settle. That is, the second POS terminal 20-2 dedicated to accounting executes the settlement process by the operation of the customer or the like.

When the registration process is completed in the registration-only first POS terminal 20-1, the customer moves from the registration-only first POS terminal 20-1 to the accounting-only second POS terminal 20-2, but moves to the destination accounting-only second POS terminal 20. Information necessary for settlement processing such as registration information is supplied to -2 from the registration-only first POS terminal 20-1. As a method of supplying registration information and the like, information necessary for settlement processing is transmitted from the registration-dedicated first POS terminal 20-1 to the accounting-dedicated second POS terminal 20-2 (may be transmitted via the store controller 30). There is a method and a method of issuing a medium (a medium on which a barcode or the like for acquiring information necessary for settlement processing is printed) on the registration-only first POS terminal 20-1.

If there are two or more accounting-dedicated second POS terminals 20-2, even if the accounting-dedicated second POS terminal 20-2 for executing the settlement process is specified in the registration-only first POS terminal 20-1. good. If the registration-only first POS terminal 20-1 issues a medium (a medium on which a barcode or the like for acquiring information necessary for settlement processing is printed), the accounting-only second POS that reads the medium is issued. The settlement process is executed at the terminal 20-2.

That is, in the semi-self mode, the product is initially registered on the clerk side of the registration-only first POS terminal 20-1. For example, the product is registered by scanning the scanner unit 212 on the clerk side of the registration-only first POS terminal 20-1. When, for example, the second POS terminal 20-2 dedicated to accounting is specified after pressing the subtotal key (for example, the subtotal key displayed on the clerk side display unit 210 or the subtotal key arranged on the key operation unit 211), The registration information is transmitted to the designated second POS terminal 20-2 dedicated to accounting, and the process is completed.

In the above example, at the end of product registration, the subtotal key is first pressed, and then (after pressing the subtotal key), the second POS terminal 20-2 dedicated to accounting is specified. At the end, the processing procedure may be such that the second POS terminal 20-2 dedicated to accounting is directly specified (without pressing the subtotal key). In the latter case, it is not necessary to display the subtotal key on the screen.

Subsequently, after receiving the registration information, the accounting-dedicated second POS terminal 20-2 designated by the registration-only first POS terminal 20-1 is settled on the customer side by, for example, a change machine 209 (step S50) and processed. Is completed. In the registration-only first POS terminal 20-1, the clerk can register the purchased product of the next customer after transmitting the registration information (or after issuing the medium). In addition, the clerk may be absent after sending the registration information.

In the above example, the accounting-dedicated second POS terminal 20-2 executes the settlement process using the registration information of the product registered in the registration-only first POS terminal 20-1. That is, the registration information used by the accounting-dedicated second POS terminal 20-2 for the settlement process is the registration information of the product registered when the registration-only first POS terminal 20-1 is operating as the registration-only mode. However, if the registration information can be transmitted to the accounting-dedicated second POS terminal 20-2 (or if the accounting ticket (registered trademark; the same applies hereinafter) can be issued), the accounting-dedicated second POS terminal 20-2 will be settled. The registration information used for processing does not necessarily have to be the registration information of the product registered when the first POS terminal 20-1 is operating as the registration-only mode.

Further, the accounting-dedicated second POS terminal 20-2 receives the registration information (or reads the accounting ticket) and executes the settlement process when operating as the accounting-dedicated mode. However, if the settlement process can be executed after receiving the registration information (or after reading the checkout ticket), when the second POS terminal 20-2 receives the registration information (or reads the checkout ticket). The operation mode does not necessarily have to be the accounting-only mode.

As an example, the second POS terminal 20-2 receives registration information from another terminal (for example, the first POS terminal 20-1) when operating in the full self mode, and uses the registration information received from the other terminal. You may execute the settlement process. Further, the second POS terminal 20-2 reads the checkout ticket issued by the other terminal (for example, the first POS terminal 20-1) while operating in the full self mode, and the checkout read from the other terminal. The settlement process may be executed using the registration information obtained from the ticket.

In this case, the second POS terminal 20-2 shifts from the full self mode to the accounting-only mode before executing the settlement processing using the registration information received from the other terminal (received from the other terminal as the accounting-only mode settlement processing). Process the registered information). In addition, the second POS terminal 20-2 shifts from the full self mode to the accounting-only mode before executing the settlement processing using the accounting ticket issued by the other terminal (in the other terminal as the accounting-only mode settlement processing). Process registration information based on issued vouchers).

The second POS terminal 20-2 does not have to shift from the full self mode to the accounting-only mode before executing the settlement process using the registration information received from the other terminal (as the settlement process of the full self mode, etc.). You may process the registration information received from the terminal). Further, the second POS terminal 20-2 does not have to shift from the full self mode to the checkout mode before executing the checkout process using the checkout ticket issued by the other terminal (the checkout process in the full self mode). You may process the registration information based on the accounting voucher issued on other terminals). In these cases, data may be transmitted / received between the plurality of POS terminals 20 and registration settlement processing may be performed between the plurality of POS terminals.

Further, the POS terminal 20 operating in the normal mode or the like shifts to the semi-self mode (accounting-only mode) after the processing is completed if the own POS terminal 20 is processing after receiving the transition instruction from the other POS terminal 20. , You may forcibly (immediately) shift to the semi-self mode (accounting-only mode) after receiving the transition instruction. For example, if a clerk receives a transition instruction while the clerk is executing the registration process, the mode immediately shifts from the normal mode to the semi-self mode (accounting-only mode), while the ongoing registration process is completed. , May be able to continue to run.

Further, the POS terminal 20 operating in the full self mode may be made to function as the semi-self mode (accounting-only mode). That is, the POS terminal 20 operating in the semi-self mode (registration-only mode) transmits registration information to the POS terminal 20 operating in the semi-self mode (accounting-only mode), and operates in the semi-self mode (accounting-only mode). The POS terminal 20 causes the POS terminal 20 to execute the settlement process, but the POS terminal 20 operating in the semi-self mode (registration-only mode) transmits registration information to the POS terminal 20 operating in the full self mode and operates in the full self mode. The POS terminal 20 may be made to execute the settlement process. When the customer is not operating the POS terminal 20 operating in the full self mode, the registration information may be transmitted from the POS terminal 20 operating in the semi-self mode (registration-only mode). If the customer is operating, the registration information may not be sent, or even if the customer is performing the operation, the registration information may be sent so that the payment will be made immediately after the customer's operation is completed. May be good.

Further, in connection with the transmission of the registration information, a transmission button may be displayed on the clerk side display unit 210 of the POS terminal 20 that is the transmission source of the registration information. On the display unit 210 on the clerk side, the send buttons for all other POS terminals on the LAN 11 are displayed so that each POS terminal can be identified (for example, a terminal number such as "Registration 1" or "Registration 2" is attached. The send button of each POS terminal (POS terminal 20 operating in semi-self mode (accounting-only mode), POS terminal 20 in full self mode) that can be a destination can be identified. It may be displayed in. One or more POS terminals 20 to be permitted as the transmission destination of the registration information from the POS terminal 20 are determined in advance (that is, the coupling between the registration side and the settlement side is determined in advance), and the send button is based on this. May be displayed.

Further, the button corresponding to the POS terminal 20 that can currently transmit the registration information and the button corresponding to the POS terminal 20 that cannot transmit the registration information may be displayed in different display modes. For example, the button corresponding to the POS terminal 20 capable of transmitting registration information is displayed in a normal display mode, and the button corresponding to the POS terminal 20 unable to transmit registration information is displayed in a special display mode (for example, gray down). It may be displayed with. Currently, the button corresponding to the POS terminal 20 that cannot send the registration information may be inoperable or operation prohibited (for example, the touch may not be effective).

Further, the status of each POS terminal 20 to which the registration information is transmitted (for example, standby, in use, near-end, near-full, offline, etc.) may be notified. For example, the status of each POS terminal 20 is shared in the LAN 11 (for example, transmission / reception of information indicating the status, centralized management in the store controller 10 or one representative POS terminal 20), and is displayed on the above-mentioned button (for example). Or in association with a button), information indicating the status of each POS terminal 20 (for example, a badge-like image displaying "waiting", "in use", "near end", etc.) may be displayed. In the case of the POS terminal 20 that operates in the full self mode, it is on standby when the customer is not operating, and when the customer starts registration, it goes from waiting to in use, and when the payment is completed, it goes on standby again from in use. Be inside. You may divide the usage into registration and settlement before and after the operation of the registration completion key (subtotal key).

Further, although it has been explained that the POS terminal 20 shifts the operation mode according to the explicit mode transition operation by the clerk, even if it is an explicit mode transition operation, the operation mode before the transition (current operation mode) and the transition destination The operation may be restricted (prohibited) depending on the operation mode, operation status, and the like.

The operation mode of the POS terminal 20 may be scheduled according to the work status of the clerk (attendance status, work schedule, work schedule). However, depending on the operation mode before migration (current operation mode), the operation mode of the migration destination, the operation status, etc., there may be cases where the control is performed according to the schedule and cases where the control is not performed according to the schedule.

As the notification of the operation mode, an example in which the POS terminal 20 displays the operation mode on the display unit (clerk side display unit 210, customer side display unit 205) has been described, but the notification mode of the operation mode is not limited to this. For example, the POS terminal 20 is provided with a patrol light (registered trademark), a display board, etc. (or a patrol light, a display board, etc. is connected to the POS terminal 20), and the operation mode of the POS terminal 20 is notified by the patrol light, the display board, or the like. You may. Further, the POS system 1 is provided with a patrol light, a display board, etc. (or the patrol light, the display board, etc. are connected to the LAN 11), and the operation mode of each POS terminal 20 in the store may be notified by the patrol light, the display board, or the like. .. By using a patrol light, a display board, or the like, the operation mode can be visually recognized even from a distance (a position away from the display unit 210 on the clerk side).

(About display in double scan mode)
In the above example, in the double scan mode, the change screen (see FIG. 12A) is displayed when the registration completion key (end (receipt) button BT40) displayed on the customer side display unit 205 is pressed. There is. In other words, the product registration is completed by the customer side (registration completion key). However, the mode for completing the product registration is not limited to this.

For example, when the subtotal key is displayed on the clerk side display unit 210 and either the subtotal key displayed on the clerk side display unit 210 or the registration completion key displayed on the customer side display unit 205 is pressed, the change is made. You may display the screen. That is, both the clerk and the customer may be able to perform the operation of completing the product registration.

Further, when both the subtotal key on the clerk side and the registration completion key on the customer side are pressed, the subplanning surface may be displayed. That is, when the subtotal key is pressed first on the clerk side (when the subtotal key is pressed), the subplan surface is displayed at the timing when the registration completion key is pressed on the customer side. If the registration completion key is pressed first on the customer side (when the registration completion key is pressed), the subplanning surface is displayed at the timing when the subtotal key is pressed on the clerk side. You may.

In the mode of displaying the subplanning surface when both the subtotal key on the clerk side and the registration completion key on the customer side are pressed, if one of the subtotal key and the registration completion key is pressed, it means that the subtotal key is pressed. May be notified to the other. For example, if the subtotal key is pressed first, it means that the subtotal key has been pressed (that is, the product registration has been performed by the clerk. For example, a message such as "The product registration by the clerk has been completed" or the like. ) May be displayed on the customer side display unit 205. On the other hand, if the registration completion key is pressed first, it means that the registration completion key has been pressed (that is, the customer has operated the product registration. For example, "the customer has completed the product registration". A message or the like) may be displayed on the display unit 210 on the clerk side.

Further, when the subtotal key is pressed, instead of or in addition to displaying the fact that the subtotal key has been pressed on the customer side display unit 205, the registration completion key displayed on the customer side display unit 205 is displayed. The display mode may be displayed by the emphasis mode (blinking or the like) until the registration completion key is pressed. Similarly, when the registration completion key is pressed, instead of or in addition to displaying the fact that the registration completion key has been pressed on the clerk side display unit 210, the subtotal displayed on the clerk side display unit 210. The display mode of the key may be displayed by the emphasis mode (blinking or the like) until the subtotal key is pressed.

In the mode of displaying the subplanning surface when both the subtotal key on the clerk side and the registration completion key on the customer side are pressed, it is prohibited to press the registration completion key until the subtotal key is pressed (for example, grayed out or hidden). Etc.), and the registration completion key may be allowed to be pressed after the subtotal key is pressed (for example, it may be displayed in a display mode that can be pressed). Alternatively, the subtotal key may be prohibited from being pressed until the registration completion key is pressed, and the subtotal key may be allowed to be pressed after the registration completion key is pressed.

In the mode of displaying the subplanning surface when both the subtotal key on the clerk side and the registration completion key on the customer side are pressed, even after the subtotal key on the clerk side is pressed, it is before the registration completion key on the customer side is pressed. Occasionally, the clerk may temporarily complete the registration and allow the product to be registered. In other words, when the subtotal key is pressed on the clerk side, the other party (customer side) is notified that the subtotal key has been pressed, but even after the subtotal key is pressed, the subplan surface is displayed. During the period (before pressing the registration completion key on the customer side), the clerk may be able to register (additionally register) the product before the product registration of the customer.

In addition, when the product is additionally registered after the operation to complete the product registration on the clerk side (when the product is additionally registered in the state where the registration is provisionally completed), in order to display the subplanning side, It is necessary for the clerk to complete the product registration again (press the subtotal key). That is, after the additional registration of the product, the subplanning surface is displayed when both the subtotal key is pressed again on the clerk side and the registration completion key is pressed on the customer side. Instead of the above, the operation of completing the product registration again on the clerk side may be unnecessary. That is, after the additional registration of the product, the subplanning surface may be displayed if the registration completion key is pressed on the customer side without pressing the subtotal key again on the clerk side.

When the subtotal key is pressed and before the registration completion key is pressed, the customer's product may be additionally registered on the clerk side as described above, but the next customer's product may be registered. good. After pressing the subtotal key and before pressing the registration completion key, the clerk side display unit 210 declares whether to additionally register the customer's product or to register the next customer's product ( It may be possible to specify). For example, it may be possible to declare by a button displayed on the display unit 210 on the clerk side.

In the double scan mode, when the same product is scanned by the customer side and the clerk side, it may be notified that the same product is scanned by the customer side and the clerk side. For example, a message such as "The same product was scanned" or "This is the XXth scan" may be displayed on the display unit. The display destination of the message may be at least the clerk side. That is, when the same product is scanned by the customer side and the clerk side, the message is always displayed on the clerk side display unit 210, but the message may or may not be displayed on the customer side display unit 205. You may. For example, when the clerk scans the same product as the product already scanned by the customer, a message is displayed on the clerk display unit 210, and the same product as the product already scanned by the clerk is displayed on the customer side. When scanning, a message may be displayed on the customer side display unit 205 and the clerk side display unit 210. Further, for example, it may be possible to control whether or not to display the above-mentioned message on the customer side display unit 205 according to the setting operation (or switching operation) of the store clerk.

Further, in the above, during the double scan mode and during product registration (registration screen), the product registered on the clerk side display unit 210 on the own side (clerk side) and the product registered on the other side (customer side). Is displayed in different display modes, and the product registered on the customer side (customer side) and the product registered on the other side (clerk side) are displayed in different display modes on the customer side display unit 205. The display mode in the side display unit 210 and the customer side display unit 205 is not limited to this.

For example, the clerk side display unit 210 does not display the product registered on the other side (customer side), but displays the product registered on the own side (clerk side), and the customer side display unit 205 displays the product registered on the other side (clerk side). You may display the products registered on your side (customer side) without displaying the products registered in). Alternatively, the clerk side display unit 210 displays the product registered on the own side (clerk side) and the product registered on the other side (customer side) in different display modes, and the customer side display unit 205 displays the product registered on the other side (clerk side). The product registered on the own side (customer side) may be displayed without displaying the product registered on the side). Alternatively, the clerk side display unit 210 displays the product registered on the own side (clerk side) without displaying the product registered on the other side (customer side), and the customer side display unit 205 displays the product registered on the own side (customer side). ) And the product registered on the other side (clerk side) may be displayed in different display modes.

Even if the clerk side display unit 210 can declare (designate) whether or not to display the product registered on the other side (customer side) on its own side (the clerk side display unit 210). good. In addition to or in addition to the above, the clerk side display unit 210 declares (or does not allow) the product registered on the own side (clerk side) to be displayed on the other side (customer side display unit 205). It may be possible to specify). In addition to or in addition to the above, the customer side display unit 205 declares (or does not allow) the product registered on the other side (clerk side) to be displayed on the own side (the customer side display unit 205). It may be possible to (specify). Both may be declared by a button displayed on the screen or the like.

In addition, during product registration, the product registered by oneself and the product registered by the other party are displayed in different display areas, and after the product is registered, the product registered by oneself and the other party are displayed. The registered product may be displayed in a common display area. That is, for example, when the registration screen is changed to the subplanning surface by pressing the subtotal key or the like, the product registered on the own side and the other side are registered on the registration screen before pressing the subtotal key or the like, which are displayed in different display areas. The product may be displayed in a common display area on the subplanning surface after pressing the subtotal key or the like.

In addition, in the clerk side display unit 210, regarding the display mode during product registration and after product registration in the clerk side display unit 210 and the customer side display unit 205, the product registered by oneself and the other party are registered. It may be possible to declare (specify) whether to display the product in a different display area or in a common display area. In addition to or in addition to the above, in the customer side display unit 205, regarding the display mode during product registration and after product registration in the customer side display unit 205, the product registered by oneself and the other party It may be possible to declare (specify) whether to display the registered product in a different display area or in a common display area. Both may be declared by a button displayed on the screen or the like.
(Switching of operation mode, etc.)
When switching the operation mode, the POS terminal 20 may display that the operation mode is switched on at least one display unit of the customer side display unit 205 or the clerk side display unit 210. For example, when switching from the full self mode to the semi-self mode (accounting-only mode), when switching (or before switching), for a predetermined time (for example, about several seconds), the customer side display unit 205 displays "Switch to accounting-only mode". You may display a message. After switching the operation mode, it may be displayed that the operation mode has been switched.

In the full self mode in which the clerk is not logged in, the POS terminal 20 determines whether to maintain the full self mode, switch to the normal mode, or switch to the double scan mode when the clerk logs in. It may be determined according to the operation of the clerk (for example, button operation).

That is, in the full self mode in which the clerk is not logged in, the POS terminal 20 is switched to a button for maintaining the full self mode, a button for switching to the normal mode, and a double scan mode when the clerk logs in. A button for switching may be displayed, and the operation mode after login may be controlled according to which button is operated. For example, if you are asked for support to leave all the product registration to the clerk (when the clerk calls), the clerk operates the button to switch to the normal mode after logging in, and the product is registered. After that, if you are asked for support (when the customer calls you, but you also want the clerk to cooperate), the clerk will double scan after logging in. If you operate the button to switch to the mode and log in for some reason (for example, check the processing status), but the customer wants to register himself or does not need the support of the clerk (or temporarily) If you just logged in to and cannot support your customers), the clerk operates a button to maintain full self mode after logging in. When the full self mode is maintained after the clerk logs in, the product name or the like of the product registered by the customer may not be displayed on the clerk side display unit 210 from the viewpoint of privacy or the like. However, information that does not affect privacy so much (cumulative amount during registration, etc.) may be displayed. By displaying the accumulated amount during registration, the clerk can appropriately confirm, for example, the right to draw lots (whether or not the purchase amount exceeds a predetermined amount, etc.), so that the lottery can be prepared in advance.

Whether or not to display the product name of the product registered by the customer on the clerk side display unit 210 in the full self mode in the clerk login state is determined by the clerk side (clerk side display unit 210) or the customer side (customer side display unit 205). ) May be set in at least one of them.

In the POS terminal 20, the login state is canceled (the login state is changed to the logout state) based on the explicit operation (logout operation) of the clerk. If a predetermined time (for example, can be set for each terminal) has passed since the last operation by the clerk (for example, if no operation is performed for the specified time) in place of or in addition to the explicit operation of the clerk, the login status is cleared. It may be done.

The hibernation state (hibernation mode) described above and the logout state may be the same. That is, the above-mentioned logout operation is an operation of the pause button. However, the hibernation state and the logout state may be different states. For example, the hibernation state (hibernation mode) may be a part of the login state (a state in which the state shifts when the hibernation button is operated in the login state). When the hibernate state and the logout state are regarded as different states, the logout operation is different from the operation of the hibernate button.

However, for products that require the intervention of a clerk (for example, products that require heating in a microwave oven, products that the clerk takes out (meat buns, cigarettes, etc.)), it is necessary to inform the clerk of the product, so regardless of the above settings. , May be displayed on the display unit 210 on the clerk side. Further, since it is necessary to inform the clerk of products that require age authentication (for example, cigarettes, alcoholic beverages, etc.), they may be displayed on the clerk side display unit 210 regardless of the above settings. It should be noted that whether or not the product or the like requires the intervention of a clerk may be determined in advance for each product.

(About the printing department)
In the above, the POS terminal 20 includes one printing unit 213 that can rotatably change the direction from the clerk side to the customer side and from the customer side to the clerk side (direction of the medium issuing port), but the medium is provided on each side. It may be provided with two printing units having an issuing port. That is, in the POS terminal 20, instead of one printing unit 213 that can rotatably change the direction of the medium issuing port, the clerk side printing unit having the medium issuing port on the clerk side and the medium issuing port on the customer side are provided. It may be provided separately from a certain customer-side printing unit.

(About the scanner part)
In the above, the customer-side scanner unit 206 is of a type that the operator (clerk, customer) holds in his hand and recognizes the identification information by bringing it close to the object (product, etc.), but other types are used. There may be. For example, it may be a fixed type that recognizes an object closer to it. The same applies to the scanner unit 212 on the clerk side.

(About analysis, etc.)
In the POS system 1, an electronic journal may be stored and used for various analyzes and the like. The electronic journal may include various information such as product information and registration information, and other output information (including information about customers). For example, the POS terminal 20 (or the store controller 10) stores an electronic journal for each transaction, and the operating status of each operation mode (for example, by time zone day of the week, by person in charge, or unconditionally, in each mode). (Operating hours, etc.) and the registration status of the clerk and the customer in the double scan mode (ratio of the number of registered clerk and the customer's products, etc. It may be different for each clerk, or the attribute of the customer (male and female age) based on the membership number etc. Etc. may be analyzed by customer). The analysis result may be output to a list or the like.

In addition, by storing, for example, the registration start time (in seconds) of the first product in each transaction and the display start time of the subplanning surface in the electronic journal, the operation mode (for example, the purchase points by operation mode, etc.) can be stored. ) (For example, the time required until the registration process is completed (until the start of the subplanning surface display), etc.) may be analyzed.

(About other displays)
Further, the POS terminal 20 may display, for example, information on errors and the like (for example, warnings on change, warnings on paper, information on calling a clerk, etc.). Further, by transmitting and receiving information via the LAN 11, information related to another POS terminal 20 may be displayed in place of or in addition to the information related to the POS terminal 20. Further, when displaying the information related to the other POS terminal 20, the display may be performed according to the position of the other POS terminal 20 (the positional relationship with the POS terminal 20).

It should be noted that each POS terminal 20 may refer to information indicating a positional relationship with another POS terminal 20 (for example, each POS terminal 20 itself may store and refer to information indicating the above positional relationship. The store controller 10 may store information indicating the positional relationship, and each POS terminal 20 may access the store controller 10 to refer to the information indicating the positional relationship), depending on the position of the other POS terminal 20. May be displayed. Alternatively, the display position may be determined in advance for each of the other POS terminals 20.

For example, the left and right display positions may be different depending on the arrangement of the POS terminals 20. As an example, the first POS terminal 20-1 is arranged on the left side (left side when viewed from the clerk side) of the second POS terminal 20-2, and the third POS terminal 20 is arranged on the right side (right side when viewed from the clerk side) of the second POS terminal 20-2. When -3 is arranged (that is, when viewed from the clerk side display unit 210 side, the first POS terminal 20-1 is arranged on the left side, the second POS terminal 20-2 is arranged in the center of the left and right, and the second POS terminal 20-2 is arranged on the right side. (When the third POS terminal 20-3 is arranged), in the clerk side display unit 210 of the second POS terminal 20-2 arranged in the center of the left and right, the first POS located on the left side with respect to the second POS terminal 20-2. Information about the terminal 20-1 may be displayed on the left side of the screen, and information about the third POS terminal 20-3 located on the right side of the second POS terminal 20-2 may be displayed on the right side of the screen.

Further, in the clerk-side display unit 210 of the first POS terminal 20-1 arranged on the left side, information on the second POS terminal 20-2 and the third POS terminal 20-3 located on the right side with respect to the first POS terminal 20-1. May be displayed on the right side of the screen. For example, the information about the third POS terminal 20-3 located farther from the first POS terminal 20-1 is to the right of the information about the second POS terminal 20-2 located closer to the first POS terminal 20-1. It may be displayed. Similarly, in the clerk side display unit 210 of the third POS terminal 20-3 arranged on the right side, the first POS terminal 20-1 and the second POS terminal 20-2 located on the left side with respect to the third POS terminal 20-3 are related. Information may be displayed on the left side of the screen. For example, the information about the first POS terminal 20-1 located farther from the third POS terminal 20-3 is to the left of the information about the second POS terminal 20-2 located closer to the first POS terminal 20-1. It may be displayed.

Further, the example shown in FIG. 1 is a display example when three POS terminals 20 are arranged in the store, but the same may be applied to two or four or more POS terminals 20. Further, in the above, the current operation mode of the own POS terminal 20 is notified (displayed), but for example, by acquiring information on the operation mode of the other POS terminal 20 via the LAN 11, the other POS terminal The current operation mode of 20 may also be notified (displayed).
