The communication unit 215 transmits and receives information to and from other devices (other POS terminals 20 and the store controller 10).

(Overview of each operation mode)
Next, 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. The operation mode described below is an operation mode during normal business (operation mode relating to product registration processing and accounting processing), and is an aggregation mode for totalizing and inquiring sales and occupancy, etc. It does not include a maintenance mode for performing setting work or maintenance work, a training mode for newcomer training, and the like. The semi-self mode is an operation mode mainly used when transmitting and receiving data between a plurality of POS terminals 20. Here, in order to describe an example in which the registration process and the settlement process are executed by one POS terminal, the normal mode and the full self mode will be described in detail below.

  Note that the registration process is a process that starts when a purchased product is first registered and ends when a registration completion key is operated. The settlement process is a process that starts when the settlement start process is performed and ends when the change has been paid out. The settlement start process is the first process for starting the settlement process, and includes, for example, selection of a payment method. The selection of the payment method includes, for example, insertion of money into the change machine 209. By inserting money into the change machine 209, payment by cash is selected. As the selection of the payment method, there are cash payment selected by depositing money into the change machine 209, cash payment, payment of various cards such as a credit card, and the like. The customer can select a preferred payment method from these payment methods. These payment methods are independently selected, but a plurality of payment methods may be selected. For example, if the total price of the purchased product is higher than the charge balance stored in the transit card, the balance of the transit card is used for payment, and the insufficient amount is paid by cash or credit card. It may be. Note that the settlement start process can be performed after the registration process is started, but can also be executed before the registration process is started. Specifically, by performing cash payment 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 for explaining the outline of the operation mode of the POS terminal.
FIG. 5 is a diagram illustrating an outline of the normal mode. FIG. 5A is a schematic diagram showing the flow of processing (product registration processing, accounting processing) and the operation of a person (clerk, customer) in the normal mode. FIG. 5B is a flowchart showing a basic flow of the operation of the POS terminal 20 in the normal mode.
FIG. 6 is a diagram schematically illustrating 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 a basic flow of the operation of the POS terminal 20 in the full self mode.

  In the following description, as a different aspect from the above-described three operation modes (normal mode, full self mode, and semi self mode), the mode in which the POS terminal 20 performs the product registration process is a registration mode, The mode in which the process is executed may be referred to as a transaction mode.

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

  In the case of the normal mode, the clerk registers the purchased product of the customer on the clerk side (the clerk side scanner section 212, the clerk side display section 210, the key operation section 211). That is, the POS terminal 20 executes the registration processing 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, and the like) (the upper part of FIG. 5A). .

  When the clerk completes the registration process, the customer checks the total price of the purchased merchandise on the clerk-side display unit 210, inserts money into the change machine 209, or operates the card settlement unit 208 to make a payment (FIG. 5). (A) lower). That is, the POS terminal 20 executes the settlement process by a customer operation or the like (insertion of money into the change machine 209, operation of the card settlement unit 208) (the lower part of FIG. 5A).

  That is, in the normal mode, as shown in FIG. 5B, the salesclerk first scans a product by the salesclerk-side scanner unit 212, for example (step S10: YES), and registers the product (step S11). After pressing a subtotal key (for example, a subtotal key displayed on the clerk side display unit 210 or a subtotal key arranged on the key operation unit 211) (step S30: YES), the customer side, for example, the change machine 209 (Step S50), and the process 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 determined), but may put money into the change machine 209 before the registration process is completed, Selection of a payment method, for example, selection of payment by the card settlement unit 208 may be performed. In other words, the POS terminal 20 can make a payment as a settlement start process before the registration process is completed, for example, before the registration process or during the pedaling process (the upper part of FIG. 5A).

  In addition, the clerk may wait until the customer completes the payment after the registration of the purchased product is completed (until the customer picks up a change or receipt). Is also good. In other words, the POS terminal 20 can register the purchased product of the next customer during the settlement process (the lower part of FIG. 5A). Further, the clerk may be absent during the checkout by the customer (the lower part of FIG. 5A). That is, during the settlement of the customer after the registration of the purchased product is completed, the customer's reception may be terminated.

  In addition, when there is change, the POS terminal 20 controls the dispensing of change and bills by the change machine 209 to prevent forgetting to take change, and a sensor or the like detects that the customer has removed the change or bill. , And controls the printing unit 213 to issue a receipt. The control for issuing a receipt after the customer removes the change / change tag is similarly performed in other operation modes. As described above, in the normal mode, there are cases where there is a clerk in front of the customer receiving the change, and there are no clerks. For example, when there is a clerk, it is not always necessary to perform the above-described control (ie, Payout of change and bills and issuance of a receipt may be performed simultaneously, or a receipt may be issued first). In addition, the timing of paying out change and bills and issuing a receipt may be controlled in accordance with 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)
The full self mode is an operation mode in which a customer performs a registration process and a customer performs a settlement process as shown in FIG. That is, as shown in FIG. 6 (B), in the case of the full self mode, the customer is in both the registration mode and the accounting mode. That is, the POS terminal 20 operates in the registration and accounting mode when viewed from the entire registration processing to the settlement processing.

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

  When the registration process is completed, the customer confirms the total price of the purchased merchandise on the customer side display unit 205, inserts money into the change machine 209, or operates the card settlement unit 208 to make a payment (FIG. 6A ) Lower row). In other words, the POS terminal 20 executes the settlement process by a customer operation or the like (insertion of money into the change machine 209, operation of the card settlement unit 208) (the lower part of FIG. 6A).

  That is, in the full self mode, as shown in FIG. 6B, on the customer side, for example, a product is scanned by 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 or the like displayed on the customer side display unit 205 shown in FIG. 11B) (step S40: YES), the customer side uses the change machine 209, for example. Payment 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, both the registration process and the settlement process are performed on the customer side, but this does not mean that the clerk cannot do anything. That is, even when the POS terminal 20 is operating in the full self mode, for example, the pressing operation of the first mode switching button BT12 displayed on the clerk side display unit 210 shown in FIG. It is possible. In the full self mode, before the start of registration, as shown in FIG. 13 (B), the text “switch to face-to-face self” is displayed on the second mode switching button BT13. Note that when the customer is registering a purchased product in the full self mode, as shown in FIG. 14B, the word “join registration” is displayed on the second mode switching button BT13, and the second mode switching button BT13 is displayed. When the mode switching button BT13 is pressed, it is possible for the salesclerk-side scanner unit 212 to register the purchased product. A state where the registration process is being executed on both the clerk side and the customer side (operation mode) may be referred to as a double scan mode.

  Further, in the full self mode, it is not possible to perform a payment start process such as depositing money into the change machine 209 before the product registration process is started, but the payment start process is performed before the product registration process is started. You may be able to do it. In this case, in the full self mode, all of the settlement start processing such as deposit and selection of a payment method using various cards may be performed, 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 start process can be selected as a payment start process using various cards so that the payment start process can be performed before the registration process, the registration start process shown in FIG. 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 reports the current operation mode. For example, the clerk-side display unit 210 may display the current operation mode. Specifically, a screen having an operation mode display section may be displayed on the clerk-side display section 210, and the current operation mode may be displayed in the operation mode display section on the screen. Also, a screen on which images (for example, button-like images) corresponding to each operation mode are arranged is displayed on the clerk-side display unit 210, and an image corresponding to the current operation mode is displayed on the screen. The image may be displayed in a display mode different from the non-corresponding image (for example, a display mode that is more conspicuous than the display mode of other images). The operation mode may be displayed on the customer display unit 205 in the same manner.

  Further, the POS terminal 20 may report information according to the current operation mode. For example, a message according to the current operation mode may be displayed on the customer side display unit 205. Specifically, when the current operation mode is the full self-mode, for example, when the customer is waiting, a message that the customer himself / herself registers the product (a message such as “Please ask the customer to scan”) is given. The information may be displayed on the customer-side display unit 205 (for example, scroll display using large characters).

(Transition of operation mode)
Next, 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 shift operation (mode switching operation) performed by a clerk. More specifically, the key operation unit 211 includes a plurality of buttons. Among the plurality of buttons, the key operation unit 211 operates according to the operation of the mode switching button 211a (see FIG. 3B) arranged at the uppermost and rightmost end. The operation mode shifts.

  In addition, since the mode switching button 211a is arranged at the corner of the key operation unit 211, it is possible to reduce operation errors when shifting the mode and easily shift the operation mode. In other words, when the mode switching button 211a is present at the corner of the key operation unit 211, for example, compared to when the mode switching button 211a is located near the center of the key operation unit 211, for example, the mode switching button 211a to be operated is Since the number of other adjacent buttons is small, an operation error such as operating another button in a hurry is unlikely to occur. In addition, since the position of the mode switching button 211a to be operated can be instantaneously specified, the mode switching operation can be performed without stress. It can be performed.

  Furthermore, since the mode switching button 211a is arranged at the upper right corner (uppermost and rightmost) of the key operation unit 211, the mode shift operation is performed not only when the clerk is at the clerk but also at the customer. It will be easier. In other words, the clerk at the customer side cannot usually visually recognize each button of the key operation unit 211, but the mode switching button 211a at the upper right end of the key operation unit 211 reaches out from the customer side, Since the mode switching button 211a to be operated can be easily recognized only by the (feeling of the hand), the clerk at the customer side can perform the mode shift 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, the mode switching button 211a is arranged at a position close to the clerk operating from the customer side, so that the clerk can easily operate. Becomes

  In the present embodiment, the mode switching button 211a is arranged at the upper right corner of the key operation unit 211. However, if the mode can be recognized only by groping (a position that can be recognized relatively easily), the mode switching button 211a 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 corner. Also, instead of or in addition to arranging the mode switching button 211a at a position that can be recognized only by groping (for example, a corner at the upper right end), it can be distinguished from other buttons even from the customer side. A mode switching button 211a may be formed on the printer. For example, the size of the mode switching button 211a may be made different from the sizes of the other buttons, or the shape of the mode switching button 211a may be made different from the shapes of the other buttons to the extent that it can be distinguished only by groping. Or 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 protruded from the other buttons). ), The feel of all or a part of the surface (the surface to be touched) of the mode switching button 211a may be made different from the feeling of the other buttons (for example, only the surface of the mode switching button 211a is rough or bumpy). The touch may be provided, or a protrusion or a depression may be provided only on the surface of the mode switching button 211a.)

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

  Next, the transition (switching) of the operation mode of the POS terminal 20 will be described. The POS terminal 20 performs an explicit mode shift operation by the store clerk (for example, as shown in FIG. 9A, the first mode switch button BT12 or the second mode switch button BT13 displayed on the store display unit 210 is pressed). The operation mode shifts in accordance with the operation, input on the operation mode setting screen, operation of the operation mode setting button, and the like. Note that the buttons (keys) used for mode switching are the key operation unit 211 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. May be used as the mode switching key (hard key) set in the above, or may be used in combination. As shown in FIG. 9A, the letters "switch to full self" are displayed on first mode switching button BT12 displayed in the normal mode. Hereinafter, a description will be given of a transition example in a case where the operation mode is switched by a pressing operation of the first mode switching button BT12.

  7 and 8 are diagrams illustrating an example of the transition of the operation mode. FIG. 7 is a flowchart showing a flow of transition from the normal mode to the full self mode. FIG. 8 is a flowchart showing a 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, for example, by pressing 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. Performed by operation. Further, when conditions such as the start of the registration process are satisfied, the transition of the operation mode by operating the first mode switching button BT12 or the second mode switching button BT13 may be prohibited. Further, in the full self mode, when the processing such as the customer-side registration processing is not performed for a predetermined 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) Prohibition of the change is released). Hereinafter, those cases will be described together.

(Transition from normal mode to full self mode)
The flowchart of FIG. 7 is always started (periodically at very short time intervals) in the POS terminal 20 (normal mode). Since the mode is the normal mode, the clerk-side scanner unit 212 is accepting and the customer-side scanner unit 206 is not accepting. Note that when the salesclerk-side scanner unit 212 is accepting, registration of a product can be performed by pressing the salesclerk-side display unit 210. Similarly, when the clerk-side scanner unit 212 is in the non-accepting state, it is impossible to register a product by pressing the clerk-side display unit 210. Similarly, when the customer-side scanner unit 206 is accepting, it is possible to register a product by pressing the customer-side display unit 205, and when the customer-side scanner unit 206 is not accepting. In this case, it is not possible to register a product by pressing the customer display unit 205. The reception at the customer-side scanner unit 206 and the clerk-side scanner unit 212 refers to reading of a purchased product or the like. Reading is possible during reception, and reading is disabled during non-reception. The reception by the customer-side scanner unit 206 and the clerk-side scanner unit 212 means the use state of the customer-side scanner unit 206 and the clerk-side scanner unit 212. Is unavailable. The unreadable state may be a state 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. The information read by the side scanner unit 206 and the clerk side scanner unit 212 may be processed so that the CPU 201 and the like do not recognize the information.

  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, scanning by the customer-side scanner unit 206 includes an operation in which a customer presses an order button to register a product when a customer order display button (preset key) or the like is displayed on the customer-side display unit 205. May be. The scanning by the customer-side scanner unit 206 includes an operation in which the store clerk presses the order button to register the product when a store order button (preset key) or the like is displayed on the store-side display unit 210. Alternatively, if a key corresponding to a product (for example, a key corresponding to a sports newspaper) is arranged on the key operation unit 211, the store clerk may perform an operation of pressing the key to register the product. May be included. When the customer-side scanner unit 206 is in the non-accepting state, an order button (preset key) for a product 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 in the non-accepting state, the clerk-side display unit 210 may not display the order button (preset key) for the product, 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, the registration may not be performed even if the key corresponding to the product on the key operation unit 211 is pressed.

Step S111: It is determined whether or not payment has been made. Payment is performed by a customer or the like inserting bills or coins into the change machine 209. If there is a deposit, the process proceeds to step S112. If there is no deposit, the process proceeds to step S113.
Step S112: A payment process is performed. In the payment processing, the received money is stored in the RAM 203, and the received money is displayed on the customer display unit 205 and the clerk display unit 210, respectively. In addition, a payment start process is performed by the payment process, and the payment process starts. Thereafter, the process proceeds to step S113.

Step S113: It is determined whether or not the mode switching button has been pressed. For example, it is determined whether the first mode switching button BT12 shown in FIG. 9A has been pressed by a clerk or the like. If the first mode switching button BT12 has been pressed, the process proceeds to step S114. If the first mode switching button BT12 has not been pressed, the process proceeds to step S115. Step S114: It is determined whether or not the registration of the purchased merchandise has been started or a payment process has been performed, and it is before the settlement. The registration of the purchased product is performed, 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 merchandise has been started or the payment processing has been performed and the payment has not yet been made, the process proceeds to step S115. In step S114, when the first mode switching button BT12 is operated, a process of shifting from the normal mode to the full self mode is performed, but after the registration process or the depositing process, the first mode switching button BT12 is performed. Even if the mode switching button BT12 is operated, the shift from the normal mode to the full self mode is prohibited, and the switching of the clerk-side scanner unit 212 and the customer-side scanner unit 206 is prohibited. For this reason, if the registration of the product has not been started and the payment processing has not been performed, or if the payment has been made, the process proceeds to step S119.

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

Step S117: It is determined whether or not the checkout button (subtotal key) is pressed. For example, it is determined whether the end (receipt) button BT40 shown in FIG. 11B has been pressed. If the checkout button has been pressed, the process proceeds to step S118. If the checkout button has not been pressed, the process returns to step S111.
Step S118: Settlement processing is performed. After the settlement process is completed, for example, a receipt is issued by the printing unit 213. Then, the flowchart of FIG. 7 ends. In addition, you may issue the receipt which printed the goods registered on the clerk side and the goods registered on the customer side so as to be distinguishable. For example, a mark such as a U.S. mark or an asterisk, an underline, or the like may be added to one of the products registered by the clerk or the customer. 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 in which the product registered on the customer side and the product registered on the clerk side are printed in different areas may be issued.

Step S119: The operation mode is shifted from the normal mode to the full self mode (registration only mode). Thereafter, the process proceeds to step S120.
Step S120: The reception of the customer-side scanner unit is started. In the full self mode, since the customer scanner unit 206 registers a purchased product, the customer scanner unit 206 that has not been accepted is being accepted. Thereafter, the process proceeds to step S121.
Step S121: Cancel the reception of the clerk-side scanner unit 212. In the full self mode, since the salesclerk-side scanner unit 212 registers the purchased product, the salesclerk-side scanner unit 212 that has been accepted is set to non-acceptance. Then, the flowchart of FIG. 7 ends.

  As described above, in the normal mode, the shift to the full self-mode is permitted until the purchased product is registered or paid (if the processing from the previous registration to the settlement is completed, the settlement is completed). The usage state of the customer-side scanner unit 206 and the clerk-side scanner unit 212 can be switched. After registration or payment of purchased merchandise, shifting to the full self-mode is prohibited until the settlement is completed, and switching of the use state 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 in FIG. 8 always starts (periodically at very short time intervals) in the POS terminal 20 (full self mode). Since the mode is the full self mode, the clerk-side scanner unit 212 is in a non-reception state, and the customer-side scanner unit 206 is in a reception state. In addition, a forced end button described later is in a non-accepting state.

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

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

  Step S154: It is determined whether or not the mode switching button has been pressed. For example, it is determined whether or not the second mode switching button BT13 shown in FIG. If the second mode switching button BT13 has been pressed, the process proceeds to step S155. If the second mode switching button BT13 has not been pressed, the process proceeds to step S158. Step S155: It is determined whether or not the registration of the purchased merchandise has been started and before the settlement. After the registration of the purchased merchandise has started and before the settlement, the process proceeds to step S156. In step S155, when the second mode switching button BT13 is operated, a process of shifting from the full self mode to the normal mode is performed, but after the registration process, the second mode switching is performed. Even if the button BT13 is operated, the transition from the full self mode to the normal mode is prohibited. As described above, when the registration processing is performed, the switching of the use state of the clerk-side scanner unit 212 and the customer-side scanner unit 206 is prohibited. Therefore, if the registration of the product 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 accepting at the start of the flowchart shown in FIG. 8, but may be switched to accepting in a later step. 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: The reception of the clerk side scanner unit 212 is started. Specifically, the clerk-side scanner unit 212 is switched from non-reception to reception. When the clerk-side scanner unit 212 is switched during reception, the mode shifts to the double scan mode in which the registration of the purchased product can be performed by both the customer-side scanner unit 206 and the clerk-side scanner unit 212. In the normal mode, when the registration process is started, even if the second mode switching button BT13 is operated, in the step S114 in FIG. In the full self mode, when the second mode switching button BT13 is operated after the registration is started, the prohibition of the clerk-side scanner unit 212 from switching from non-accepting to accepting is released, and the clerk-side scanner unit 212 Starts reception. Thereafter, the process proceeds to step S155.

Step S158: It is determined whether or not the commodity has been scanned by the customer-side scanner unit 206. Whether or not the customer has scanned the merchandise by the customer-side scanner unit 206 is determined by whether or not the customer-side scanner unit 206 has scanned a barcode attached to the purchased merchandise. If the customer-side scanner unit 206 scans the purchased product, the process proceeds to step S159. If the customer-side scanner unit 206 has not scanned the purchased merchandise, 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. If the clerk-side scanner unit 212 scans the purchased product, the process proceeds to step S161. If the clerk-side scanner unit 212 has not scanned the purchased merchandise, the process proceeds to step S163.

Step S161: The purchased merchandise is registered in the RAM 203. Specifically, various information such as product information in a 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 checkout button has been pressed. For example, it is determined whether or not the checkout button (the end (receipt) button BT40 shown in FIG. 14A) has been pressed. If the checkout button has been pressed, the process proceeds to step S170. If the checkout button has not been pressed, the process returns to step S151.

Step S163: It is determined whether the time limit has elapsed. Specifically, it is determined whether or not the time set in the timer in step S152 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 a forced termination button. For example, as shown in FIG. 15, below the clerk-side display unit 210 in the full self mode, a forced end button BT14 for forcibly terminating the full self mode and shifting to the normal mode, and switching from the full self mode to the double scan mode. A clerk participation button BT15 to be switched is displayed. The forcible end button BT14 and the clerk participation button BT15 are displayed vertically above and below the center of the clerk side display unit 210. When the forced termination button BT14 starts accepting, the clerk or the like presses and operates the forced termination button BT14 to forcefully terminate the full self mode and shift to the normal mode. Before the reception of the forced end button is started, as shown in FIG. 14B, the forced end button BT14 is displayed in a grayed-down manner. At this time, instead of displaying the forced termination button BT14 in a grayed-down manner, the forced termination 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 cannot be performed. Therefore, by starting reception of the forced termination button, switching from reception of the customer-side scanner unit 206 to non-reception is released.
Step S165: It is determined whether the forced termination button has been pressed. Specifically, it is determined whether or not the forced termination button BT14 shown in FIG. 15 has been pressed and operated by a clerk or the like. If the forced end button has been pressed, the process proceeds to step S166. If the forced termination button has not been pressed, the process proceeds to step S162.
Step S166: End the full self mode. After ending the full self mode, the mode shifts to the normal mode. When the forced termination is performed, the registration information and the like on the registered and unpaid products are discarded (erased). Then, the flowchart of FIG. 8 ends. After the forced termination, the full self mode may be maintained, the mode may be shifted to an operation mode other than the normal mode, or the operation mode to be shifted may be specified. Further, the registration information need not be discarded after the forced termination.

Step S167: The operation mode is shifted from the full self mode (registration only mode) to the normal mode.
Step S168: The reception of the clerk side scanner unit is started. In the normal mode, since the salesclerk-side scanner unit 212 registers the purchased merchandise, the salesclerk-side scanner unit 212 that has not been received is set to be receiving.
Step S169: Cancel the reception of the customer-side scanner unit 206. In the normal mode, the clerk-side scanner unit 212 registers the purchased merchandise, so that the customer-side scanner unit 206 that has been accepted is set to non-accepting. Then, the flowchart of FIG. 8 ends.
Step S170: Settlement processing is performed. After the settlement process is completed, for example, a receipt is issued by the printing unit 213, for example. 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 paid, and the usage state of the customer-side scanner unit 206 and the clerk-side scanner unit 212 can be switched. Further, after the purchase or registration of the purchased merchandise, the shift to the full self mode is prohibited until the settlement is completed. Instead, the mode shifts to the double scan mode. For this reason, the switching of the use state of the customer-side scanner unit 206 and the clerk-side scanner unit 212 is prohibited until the settlement is completed after the purchase or registration of the purchased merchandise. Is released.

  Further, when the full self mode is started, since the product is registered by the customer, the switching of the use state of the customer-side scanner unit 206 is prohibited, but a long time elapses without performing the operation on the customer side. Then, it is conceivable that the customer canceled registration by the customer-side scanner unit 206 halfway before the settlement was completed. For this reason, when the time limit elapses without the customer's operation being performed, the prohibition of the switching of the use state of the customer-side scanner unit 206 is released, the mode is changed from the full self mode to the normal mode, and the customer-side scanner unit is switched. 206 is not accepted.

  Note that, in the full self mode, if the deposit processing is enabled before the registration processing is started in the same manner as in the normal mode, in step S152, the timing at which the second mode switching button BT13 is pressed is determined after the registration starts. Instead of determining that the mode is shifted from the full self mode to the normal mode when the balance is not settled, the mode is shifted from the full self mode to the normal mode when the timing at which the second mode switching button BT13 is pressed is not before the start of registration or payment. You may make it. In the steps shown in FIGS. 7 and 8, an example in which the settlement start process is payment to the change machine 209 has been described, but when the change machine 209 is paid when another payment start process is performed. The same processing as described above may be performed.

(Display during normal mode)
Next, the display in the normal mode will be described with reference to FIGS. 9 to 12 show 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 a registration screen displayed on the clerk-side display unit 210 of the POS terminal 20, and is a display example of a registration start screen before a product is purchased. 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 performs an operation (touch) of pressing the subtotal button BT10 after completing the product registration. The pause button BT11 is a button for pausing the POS terminal 20. The clerk operates the pause button BT11 when leaving the POS terminal 20 (for example, when searching for a product or when not using 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 the mode. On the first mode switching button BT12, the words "switch to full self" are displayed. The first mode switching button BT12 is grayed-out when mode switching is prohibited and the operation of the button is not valid. The display may not be performed in place of the gray-down display. Further, since it is difficult to imagine an opportunity to operate the subtotal button BT10 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 a product is registered at the beginning of a transaction.

  FIG. 9B is a display example of a screen displayed on the customer-side display unit 205 of the POS terminal 20 and is a display example before a product is purchased. In the screen shown in FIG. 9B, a clerk call button BT33 is displayed on the lower left side, and 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 needs support). 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 characters indicating the language are displayed in each language.

  In the message display section at the bottom of the screen, a message "You can put money anytime" is displayed, and in the center of the screen, an image simulating the state of putting money into the change machine 209 is displayed. When the money is inserted into the change machine 209, the screen shown in FIG. 10 (B) on which the information regarding the registered product, the score and the amount of the registered product accompanying the registration of the product are not displayed is displayed on the customer side. It is displayed on the unit 205.

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

  FIG. 10B is a display example of a screen displayed on the customer-side display unit 205 of the POS terminal 20 and is a display example during registration of a product, and is illustrated in FIG. It is a screen displayed on the customer side display unit 205 when an image is displayed on the clerk side display unit 210. On the screen shown in FIG. 10 (B), the product name of the registered product (can beer, asparagus) is displayed at the top, and the product name (aspara) of the currently registered product is displayed at the bottom left along with the respective registered points and the amount. ing. Below that, the points and the total amount of the registered merchandise, and the deposit amount are displayed. The deposit amount is the amount of money that has been inserted from the change machine 209. On the screen shown in FIG. 10B, a clerk call button BT33 is displayed on the right side, and 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 shown in FIG. 9B.

  FIG. 11A is a display example of a screen displayed on the clerk-side display unit 210 of the POS terminal 20, which is a display example during the settlement. Specifically, FIG. 10A shows that when the registration screen is displayed, the total amount is displayed as “total” on the screen in the state where the product is registered last, and for the change machine 209. This is a screen in which 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 deposit amount.

  At the lower right of the change machine deposit amount, a deposit cancel button BT18 is provided. The payment cancel button BT18 is a button for canceling payment to the change machine 209. The clerk received from the customer who has received the payment cancellation request presses the payment cancellation button BT18 to cancel the payment. When the deposit is canceled, the change machine 209 refunds money corresponding to the deposit to the customer. The money to be repaid may be the money inserted by the customer, or may be the same amount of money as the money inserted by the customer. Note that the payment cancel button BT18 is displayed on the clerk-side display unit 210 and is not displayed on the customer-side display unit 205. For this reason, the customer cannot perform the operation of canceling the deposit, and when the customer wants to return the deposited money, the customer has to ask the clerk. The payment cancel 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 the first mode switching button BT12 shown in FIG. 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, a message “Press the end button if you like” is displayed, the payment amount (here, “383 yen”), the deposit amount ( Here, “1,000 yen” and a 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 has put into the change machine 209. The change is the amount obtained by subtracting the payment amount from the deposit amount. An end (receipt) button BT40 is displayed below the box 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 determined, the payment is executed, and the change machine 209 discharges the change (here, “617 yen”).

  FIG. 12A shows an adjustment screen (change screen) displayed when a change is released. For example, when the end (receipt) button BT40 is operated, the POS terminal 20 displays a change screen as shown in FIG. By displaying the change screen shown in FIG. 12 (A), the customer is prompted to remove the change. FIG. 12B shows 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, a 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 be provided with a sensor such as a photo sensor in the vicinity of the take-out opening, 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, a display in the full self mode will be described with reference to FIGS. 13 and 14 show display examples of the customer display unit 205 and the clerk display unit 210 in the full self mode, and FIG. 15 shows display examples of the clerk display unit 210 in the full self mode. FIG. 13A is a display example of a 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, a registration start button BT30 is displayed on the right side of the screen, and display language switching buttons BT35 to BT37 are displayed on the lower left 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.

  FIG. 13B is a display example of a registration start screen displayed on the clerk-side display unit 210 of the POS terminal 20 before the start of product registration. On the screen shown in FIG. 13B, a second mode switching button BT13 is displayed in addition to the screen shown in FIG. On the screen shown in FIG. 13B, a registration start button BT30 and display language switching buttons BT35 to BT37 are displayed, but these buttons are disabled. Inoperable means that the button does not respond when pressed, or when the button responds when pressed, but the predetermined function is not exhibited even when 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 does, the product registration does not start.

  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, like 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 commodity 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 displayed in a grayed-down state.

  FIG. 14A is a display example of a registration screen displayed on the customer side display unit 205 of the POS terminal 20 before product registration is started. More specifically, FIG. 14A shows the display contents of a registration screen in a situation where two items of goods (daifuku mochi) are registered. When the registration start button BT30 is operated on the registration start screen shown in FIG. 13A, a registration screen in which no product is registered yet (a registration screen in an initial state) is displayed. For convenience of explanation, FIG. 14A shows a registration screen after a product has already been registered.

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

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

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

  FIG. 14B is a display example of a registration screen displayed on the clerk-side display unit 210 of the POS terminal 20 after the commodity registration is started. On the screen shown in FIG. 14B, a second mode switching button BT13 is displayed in addition to the screen shown in FIG. The registration start button BT30 and the display language switching buttons BT35 to BT37 displayed on this screen are inoperable similarly to the registration start button BT30 and the display language switching buttons BT35 to BT37 shown in FIG. When the store clerk presses the second mode switching button BT13 after the commodity registration is started, the mode shifts from the full self mode to the double scan mode. For this reason, the words "Join registration" are displayed on the second mode switching button BT13. In other words, it means that the mode shifts to the double scan mode in which the clerk participates in the registration while the customer is registering the product in the full self mode. Note that the second mode switching button BT13 is displayed as “Switch to face-to-face self” for switching from the full self mode to the normal mode before registration or settlement starts, and after the registration or settlement starts, the full self mode is set. "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 separately provided. In this case, these mode switching buttons are arranged at different positions on the clerk-side display unit 210. When these mode switching buttons are not being accepted, they may be displayed in a grayed-down state or may not be displayed.

  The screen illustrated in FIG. 14B is a display example before reception of a forced end button is started. For this reason, since the reception of the forced end button has not been started, the forced end button BT14 is displayed in a grayed-down state. At this time, the forced end button BT14 may not be displayed.

  FIG. 15 is a display example of a screen displayed on the clerk-side display unit 210 of the POS terminal 20, which is a display example after registration of a product by a customer is started and before reception of a forced termination button is started. . On the screen shown in FIG. 15, the forced end button BT14 displayed in gray down in FIG. 14B is displayed and can be pressed. When the forced termination button BT14 is pressed while the forced termination button BT14 is displayed, the full self mode is forcibly terminated, and the operation mode shifts to the normal mode.

(Display during double scan mode)
When the mode is shifted 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. In addition to the products registered by the side scanner unit 206, the products registered by the clerk by 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 that of the product registered by the customer-side scanner unit 206. The different display mode is, for example, a mode in which the font changes or the background color changes.

  The clerk-side display unit 210 has the same screen as the screen displayed in the normal mode. The registered products include, in addition to the product registered by the clerk at the clerk-side scanner unit 212, the customer The merchandise registered by the scanner unit 206 is also included. Further, at the time of settlement, both the customer-side display unit 205 and the clerk-side display unit 210 have the same screen as that 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 clerk-side scanner unit 212.

  When the end (receipt) button BT40 is pressed, a change screen as shown in FIG. 12A is displayed. By displaying the change screen shown in FIG. 12 (A), the customer is prompted to remove the change. FIG. 12B shows a settlement screen (receipt screen) displayed when the change is removed. For example, when the change is removed from the exit of the change machine 209, the POS terminal 20 displays a receipt screen as shown in FIG. The POS terminal 20 may be provided with a sensor such as a photo sensor in the vicinity of the take-out opening, 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, after the registration of the purchased merchandise is started, it is hard to imagine switching to the full self mode or the normal mode. It is considered that the operation of switching the operation mode in such a situation is not an intentional operation but is likely to be an erroneous operation. In this regard, according to the POS terminal 20, the mode switching is prohibited after the registration of the purchased product is started. Specifically, the mode is switched from the normal mode to the full self mode and from the full self mode to the normal mode. Switching to is prohibited. Therefore, unintended switching of the operation mode can be prevented.

  Further, for example, when 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 registrations of the purchased product increases, the operation of the cash register decreases, and it takes time to settle the product, and the customer may wait.

  In this regard, in the POS terminal 20, since the mode switching is prohibited after the registration of the purchased merchandise is started, the use state of the clerk-side scanner unit 212 is switched (switching between accepting and non-accepting). Is forbidden. Therefore, it is possible to reduce the possibility of re-registering the purchased merchandise, so that the merchandise can be settled smoothly. As a result, it is possible to suppress a 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, when a customer is not used to registering a product and takes longer to register a product than other customers, it is assumed that a plurality of POS terminals 20 are provided. However, the time required for processing from registration to settlement at the POS terminal 20 becomes long, and there is a concern that the overall operation of the POS system 1 may be reduced. In this regard, in the POS terminal 20, when the customer is registering in the full self mode, the prohibition of the switching of the operation mode and the prohibition of the switching of the use state of the clerk-side scanner unit 212 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 made equal to or longer than the other POS terminals 20. Therefore, it is possible to suppress a decrease in the operation of the cash register, and it is possible to prevent the customer from waiting.

  If no operation is performed on the customer side of the POS terminal 20 during the full self mode, it is assumed that there is no customer near the POS terminal 20. The reason that there is no customer near the POS terminal 20 may be that the customer interrupted (stopped) the registration of the product on the way and left the product as it was. If there is no customer near the POS terminal 20 and the POS terminal 20 is in the full self mode, the POS terminal 20 cannot be used, 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 customer's last operation, such as scanning on the customer-side scanner unit 206 or operation on the customer-side display unit 205, is accepted during the full self-mode, in other words, For example, when the operation on the customer side has not been performed for more than the time limit, the POS terminal 20 is forcibly terminated by returning to the full self mode by operating the forced termination button BT14 displayed on the clerk side display unit 210. Like that. For this reason, even when the customer registers at the POS terminal 20 in the full self-mode and interrupts the registration of the product on the way, the POS terminal 20 can be opened to other customers. Therefore, a decrease in the operation of the POS terminal 20 can be suppressed.

  Further, as a situation where there is no customer near the POS terminal 20, it is assumed that the customer who has started to register recalls a product that he or she has forgotten to purchase and takes it out of the sales floor. In this case, the customer has interrupted the registration of the product, but has an intention to restart. In this case as well, if the POS terminal 20 is forcibly terminated, there is a possibility that the same product may need to be registered again. In this regard, in the POS terminal 20, a time limit is provided until the forced termination is performed. Therefore, even if there is no customer near the POS terminal 20, the POS terminal 20 is not forcibly terminated immediately. You can save time and effort. Assuming that the customer who started registration remembers the product that he or she has forgotten to purchase and takes it from the counter, the time limit is preferably set to, 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 an operation of pressing a forced termination button BT14 displayed on the clerk side display unit 210. For this reason, it is possible to prevent the customer from forcibly terminating, so that trouble between the customers can be avoided. Also, 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 greatly exceeded. Discomfort given to a customer who has gone can be reduced.

  When the POS terminal 20 is forcibly terminated, the registration information of the merchandise registered by the customer-side display unit 205 or the customer-side scanner unit 206 is discarded. For this reason, for example, in the case where the customer is forced to end by leaving the POS terminal 20, the burden on the settlement process can be reduced. The registration information may be held without being destroyed.

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

(About error display)
In the 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 before the settlement after the registration is started. In this case, the operation mode is continued 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 is displayed on the clerk side display unit 210 or the customer side display unit 205. Is not displayed, but 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 performing such an error display, the clerk can easily recognize the prohibition of the switching of the operation mode.

  For example, when the first mode switching button BT12 is operated before the settlement after the start of registration when the operation mode is the normal mode, a display based on the operation of the first mode switching button BT12 is shown in FIG. Thus, an error screen may be displayed during the normal mode. The normal mode error screen is a screen in which the normal mode error display GA50 is displayed on the screen displayed on the clerk side display unit 210 in the normal mode. In the normal mode error display GA50, the message "Error Product registration (payment). Do you want to switch to full self and leave the product registration?" Is displayed and the text "Leave it" Are displayed, and a reject button BT52 on which the character "No" is described is displayed.

  When the clerk presses the accept button BT51, the operation mode shifts from the normal mode to the full self mode. When the mode is shifted to the full self mode, the registration screen shown in FIG. Further, a mirror screen shown in FIG. 14B is displayed on the clerk-side display unit 210. For this reason, although the transition from the normal mode to the full self mode is basically prohibited before the settlement after the registration is started, when the operation mode transition request (depression of the acceptance button BT51) is issued by a clerk or the like, the normal mode is normally set. It is possible to shift from the mode to the full self mode. When shifting from the normal mode to the full self mode, the store clerk may be performing a product registration process in the normal mode. In this case, the information of the registration process is taken over in the full self mode as it is. For this reason, duplication of registration processing can be suppressed, and the burden can be reduced, so that the settlement can be performed smoothly. When the clerk presses the reject button BT52, the normal mode error display GA50 is cleared while the operation mode remains the normal mode.

  When the operation mode is the full self mode and the second mode switching button BT13 is operated before the settlement after the registration is started, the display based on the operation of the second mode switching button BT13 is shown in FIG. As shown, an error screen may be displayed during the full self mode. The error screen during full self mode is a screen in which the error display GA60 during full self mode is displayed on the screen displayed on the clerk display unit 210 during the full self mode. In the error display GA60 during the full self mode, a message “Error, customer is in use. Switch to face-to-face self and take over the product registration?” Is displayed, and the text “take over” is written. An accept button BT61 and a reject button BT62 on which the letters "NO" are described are displayed.

  When the clerk presses the accept button BT61, the operation mode shifts from the full self mode to the normal mode. When the mode is shifted to the normal mode, the registration screen shown in FIG. In addition, a screen shown in FIG. 10B is displayed on the customer side display unit 205. For this reason, the transition from the full self mode to the normal mode is basically prohibited before the settlement after the registration is started. However, when the operation mode transition request (pressing of the acceptance button BT61) is issued by a clerk or the like, the full self mode is reduced. The transition from the self mode to the normal mode is enabled. When shifting from the full self mode to the normal mode, the customer may be performing a product registration process in the full self mode. In this case, the information of the registration process is taken over as it is in the normal mode. For this reason, duplication of registration processing can be suppressed, and the burden can be reduced, so that the settlement can be performed smoothly. When the clerk presses the reject button BT62, the error display GA60 during the full self mode is erased while the operation mode remains the full self mode.

  When 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, a display based on the operation of the forced end button BT14 is displayed as shown in FIG. As shown in (1), an error screen before 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 display unit 210 during the full self mode. In the error display before forcible termination GA70, a message "Error Product registration (payment is in progress. The mode cannot be switched)" is displayed, and a cancel button BT71 with the text "Erase" is displayed. Is displayed. By pressing this cancel button BT71, the error display GA70 before forced termination is deleted while the operation mode remains the full self mode.

  In addition, when there is an operation mode shift request (depression of the acceptance button BT51) by a clerk or the like shown in FIG. 16A and the shift from the normal mode to the full self mode, when the clerk is performing a product registration process, the normal The registration information registered in the mode may not be transferred to the full self mode. Similarly, when there is an operation mode request (depression of the acceptance button BT61) by a clerk or the like shown in FIG. 16B, and when shifting from the full self mode to the normal mode, the customer is performing a product registration process, The registration information registered in the full self mode may not be taken over to the normal mode. In these cases, instead of not being able to inherit 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. When the registration information is discarded, confusion in the subsequent processing can be avoided. Further, when the registration information is suspended, the subsequent payment processing 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 salesclerk-side display unit 210 displays as shown in FIG. A registration information processing selection screen is displayed. The registration information selection screen is a screen in which a registration information processing selection display GA80 is displayed on a screen displayed on the clerk side display unit 210 during the full self mode. In the registered information processing selection display GA80, a message "Transfer to face-to-face self. There is registered data. Do you want to discard / hold?" Is displayed, and the word "Discard" is written. A discard button BT81 and a hold button BT82 on which characters "HOLD" are described 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 in the normal mode shown in FIG. When the hold button BT82 is pressed, a normal mode registration start screen shown in FIG. On the registration start screen shown in FIG. 18B, a first hold display tab TAB91 and a second hold display button BT92 relating to 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 and the amount information is displayed, and the transaction including the held registration information is resumed. Can be.

  When the registration information is suspended, only one of the first suspension display tab TAB91 and the second suspension display button BT92 may be displayed, or the suspension display button or the like may be displayed in another mode. Alternatively, 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. When resuming the transaction, the transaction may be resumed in the mode at the time of suspension (here, the full self mode) or may be resumed in the current mode (here, the normal mode). Alternatively, the operation mode at the time of restart may be selectable.

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

(Registration of customer image)
The POS terminal 20 may be provided with an imaging unit (camera) for imaging the customer side, and may capture an image (customer image) such as the face of the customer. For example, the customer image is captured at the time of starting a transaction, and is stored in the RAM 203 or the like in association with a transaction code (automatic numbering) assigned to each transaction, or data of a face image is stored in the store controller 10. , And may be stored in the store controller 10.

  When discarding or suspending the registration information, a 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, the customer who has registered the discarded or saved registration information can be easily specified.

  Further, instead of or together with the photographing means, a specifying means for specifying a customer may be provided. As the specifying 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 for specifying the customer may be used. Alternatively, when the customer has a membership card or the like and 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. The customer who registered the discarded or stored registration information can also be easily specified by these specifying means.

(About operation mode)
The POS terminal 20 activates the first mode switching button BT12 or the second mode switching button BT13 before the registration or payment of the purchased product (or, if the processing from the previous registration to the settlement is completed, after the settlement is completed). Is pressed, the mode shifts from the normal mode to the full self mode and from the full self mode to the normal mode. When the second mode switching button BT13 is pressed in the full self mode, the mode shifts from the full self mode to the double scan mode. However, the transition may be performed under another condition. For example, the operation mode of the POS terminal 20 may be changed according to an operation other than an explicit mode change operation performed by a store clerk (for example, reading a store clerk code). For example, in the full self mode, the POS terminal 20 reads the clerk code instead of pressing the second mode switching button BT13 or simultaneously with the pressing of the second mode switching button BT13 when the purchased product is registered and before the settlement. Thus, the mode may shift from the full self mode to the double scan mode.

  In addition, the POS terminal 20 has predetermined conditions (e.g., conditions related to time such as elapsed time and predetermined time (schedule), conditions related to transmission / reception of information such as instructions to / from other terminals, etc.) that do not depend on operations of a clerk. The operation mode may shift based on the above. Specifically, for example, the POS terminal 20 in the normal mode does not use the POS terminal 20 until the purchased product is registered or paid (if the processing from the registration to the payment has been performed last time, the payment has been completed). If the state continues, the mode may shift 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. . Alternatively, the operation mode may be shifted by operating the key operation unit 211 instead of the operation of pressing the second mode switching button BT13 displayed on the clerk side display unit 210. Note that a button corresponding to each clerk may be arranged on the key operation unit 211, and the clerk may be specified according to the button operated on the key operation unit 211.

(About semi-self mode)
The POS terminal 20 is used by itself to register and settle goods at the POS terminal. However, a POS system in which a plurality of POS terminals 20 are connected via a LAN or the like is used, and registration and settlement are performed at different POS terminals 20. You may. For example, the merchandise registered at the first POS terminal 20-1 may be settled at the second POS terminal 20-2. The POS terminal 20 that performs the payment includes a normal mode, a full self mode, and a double scan mode as operation modes, and a semi-self mode (accounting-only mode) that performs only payment without registering a product. As a mode of operating the POS terminals 20 in the semi-self mode, for example, in two or more POS terminals 20, some of the 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, of the first POS terminal 20-1 and the second POS terminal 20-2 shown in FIG. 1, the first POS terminal 20-1 in the registration-only mode is referred to as the first POS terminal 20-1 for the registration, and the second POS in 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 as the second POS terminal 20-2 dedicated to accounting in the semi-self mode, the clerk registers the purchased product of the customer in the first POS terminal 20-1 dedicated to registration. When the registration process by the clerk is completed, the customer moves to the second POS terminal 20-2 dedicated to accounting, checks the total price of the purchased product on the clerk side display unit 210, and inserts money into the change machine 209, or The settlement unit 208 is operated to settle the payment. In other words, the second POS terminal 20-2 for accounting performs the settlement process by a customer operation or the like.

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

  If there are two or more accounting-only second POS terminals 20-2, the accounting-only second POS terminal 20-2 for executing the settlement process is designated in the registration-only first POS terminal 20-1. Good. In the case where 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 the settlement process is printed), the accounting-only second POS that reads the medium is issued. The settlement process is executed in the terminal 20-2.

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

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

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

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

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

  As an example, when operating in the full self mode, the second POS terminal 20-2 receives registration information from another terminal (for example, the first POS terminal 20-1) and uses the registration information received from the other terminal. Payment processing may be performed. When operating in the full self mode, the second POS terminal 20-2 reads a bill issued at another terminal (for example, the first POS terminal 20-1), and reads the bill 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 payment processing using the registration information received from the other terminal (the payment processing from the other terminal is performed as the payment processing in the accounting-only mode). Process the registration information that you have). In addition, the second POS terminal 20-2 shifts from the full self mode to the accounting-only mode before executing the settlement process using the bill issued at the other terminal. Process registration information based on issued vouchers).

  Note that the second POS terminal 20-2 does not need to shift from the full self mode to the accounting-only mode before executing the payment process using the registration information received from the other terminal (as the payment process in the full self mode, It may process the registration information received from the terminal). In addition, the second POS terminal 20-2 does not have to shift from the full self mode to the accounting only mode before executing the payment processing using the bill issued at the other terminal (the payment processing in the full self mode). May process registration information based on a bill issued in another terminal). In these cases, data transmission / reception may be performed between the plurality of POS terminals 20, and registration settlement processing may be performed between the plurality of POS terminals.

  Also, the POS terminal 20 operating in the normal mode or the like shifts to the semi-self mode (accounting only mode) after the end of the processing if the own POS terminal 20 is processing after receiving the shift instruction from another POS terminal 20. Alternatively, the mode may be forcibly (immediately) shifted to the semi-self mode (accounting-only mode) after receiving the shift instruction. For example, if the clerk is executing a registration process on the clerk side and receives a shift instruction, the clerk immediately shifts from the normal mode to the semi-self mode (accounting only mode), while the running registration process is completed. , May be executed continuously.

  Further, the POS terminal 20 operating in the full self mode may 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 (account-only mode), and operates in the semi-self mode (account-only mode). The POS terminal 20 performs the settlement process. 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 execute the settlement process. Note that, when a customer does not operate the POS terminal 20 operating in the full self mode, registration information may be transmitted from the POS terminal 20 operating in the semi self mode (registration only mode). If the customer is performing the operation, the registration information may not be transmitted, or even if the customer is performing the operation, the registration information may be transmitted so that the settlement is performed immediately after the operation of the customer is completed. Is also 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. The clerk-side display unit 210 displays transmission buttons for all other POS terminals on the LAN 11 so that each POS terminal can be identified (for example, by attaching terminal numbers such as “register 1” and “register 2”). Display, etc.), and the transmission buttons of the POS terminals that can be transmission destinations (POS terminals 20 operating in the semi-self mode (accounting-only mode) and POS terminals 20 in the full self mode) can identify the respective POS terminals. May be displayed. One or more POS terminals 20 to be permitted as destinations 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 based on this, the transmission button May be displayed.

  Further, a button corresponding to the POS terminal 20 that can transmit the registration information and a button corresponding to the POS terminal 20 that cannot transmit the registration information may be displayed in different display modes. For example, a button corresponding to the POS terminal 20 to which registration information can be transmitted is displayed in a normal display mode, and a button corresponding to the POS terminal 20 to which registration information cannot be transmitted is displayed in a special display mode (for example, gray-down). May be displayed. The button corresponding to the POS terminal 20 to which the registration information cannot be transmitted at present may be inoperable or 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, waiting, 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 and reception of information indicating the status, unified management of the store controller 10 and one representative POS terminal 20 and the like), and ( Alternatively, 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 operating in the full self mode, the POS terminal 20 is on standby when the customer is not operating. When the customer starts registration, the POS terminal 20 changes from the standby state to the in-use state. Inside. The status of use may be divided into a status during registration and a status during settlement before and after operation of a registration completion key (subtotal key).

  Also, the POS terminal 20 has been described to change the operation mode according to the explicit mode change operation by the clerk. However, even when the mode change operation is performed explicitly, the operation mode before the change (current operation mode) and the transfer destination The operation may be restricted (prohibited) depending on the operation mode, operation status, and the like of the operation.

  The operation mode of the POS terminal 20 may be scheduled according to the work status of the clerk (work status, work schedule, work schedule). However, depending on the operation mode before the transition (current operation mode), the operation mode at the transition destination, the operation status, and the like, there may be a case where control is performed as scheduled and a case where control is not performed as scheduled.

  As the notification of the operation mode, an example in which the POS terminal 20 displays the operation mode on the display unit (the clerk-side display unit 210 and the customer-side display unit 205) has been described, but the notification mode of the operation mode is not limited thereto. For example, the POS terminal 20 includes a patrol light (registered trademark), a display board, or the like (or connects the patrol light, the display board, or the like to the POS terminal 20), and notifies the operation mode of the POS terminal 20 by the patrol light, the display board, or the like. May be. Further, the POS system 1 may include a patrol light, a display board, or the like (or connect the patrol light, the display board, or the like to the LAN 11), and notify the operation mode of each POS terminal 20 in the store 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 from a distance (a position away from the clerk-side display unit 210).

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

  For example, a subtotal key is displayed on the clerk side display section 210, and a change is made when either the subtotal key displayed on the clerk side display section 210 or the registration completion key displayed on the customer side display section 205 is pressed. A screen may be displayed. That is, both the clerk and the customer may be able to perform an operation to complete the product registration.

  Further, when both the subtotal key on the clerk side and the registration completion key on the customer side are depressed, the sub-planning plane may be displayed. That is, if the subtotal key is pressed by the clerk first (when the subtotal key is pressed), the sub-planning plane is displayed at the timing when the registration complete key is pressed by the customer. If the customer has pressed the registration completion key first (when the registration completion key has been pressed), the clerk displays the sub-planning plane at the timing when the subtotal key is pressed. You may.

  In a mode in which the sub-planning screen is displayed when both the clerk's subtotal key and the customer's registration completion key are pressed, if one of the subtotal key and the registration completion key is pressed, the fact that the key is pressed is May be notified to the other. For example, if the subtotal key is pressed first, a message indicating that the subtotal key has been pressed (that is, a product registration operation has been performed by the clerk. For example, a message such as "product registration has been completed by the clerk" ) 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 performed a product registration operation. A message or the like may be displayed on the clerk-side display unit 210.

  When the subtotal key is pressed, instead of or in addition to displaying on the customer side display unit 205 that the subtotal key has been pressed, the registration completion key displayed on the customer side display unit 205 is displayed. The display mode may be displayed in a highlighted mode (flashing or the like) until the registration completion key is pressed. Similarly, when the registration completion key is pressed, the subtotal displayed on the clerk side display section 210 is displayed instead of or in addition to displaying on the clerk side display section 210 that the registration completion key is pressed. The key display mode may be displayed in an emphasis mode (flashing or the like) until the subtotal key is pressed.

  In a mode in which the subplan key is pressed when both the subtotal key on the clerk side and the registration completion key on the customer side are pressed, pressing of the registration completion key is prohibited until the subtotal key is pressed (for example, gray-down, non-display) Etc.), and then, after the subtotal key is pressed, pressing of the registration completion key may be permitted (for example, display in a pressable display mode). Alternatively, the pressing of the subtotal key may be prohibited until the registration completion key is pressed, and the pressing of the subtotal key may be permitted after the registration completion key is pressed.

  In a mode in which the sub-planning screen is displayed when both the clerk's subtotal key and the customer's registration completion key are pressed, even after the clerk's subtotal key is pressed but before the customer's registration completion key is pressed. At this time, the registration may be temporarily completed on the clerk side, and the registration of the product may be permitted. That is, when the subtotal key is pressed by the clerk, the fact that the subtotal key has been pressed is notified to the other party (the customer side), but even after the subtotal key is pressed, the subplanning plane is displayed. During the period (before the customer's registration completion key is pressed), the store clerk may be able to register (additionally register) the product of the customer before the product registration.

  In addition, if the product is additionally registered after the operation of completing the product registration on the clerk side (when the product is additionally registered in the state of the temporary registration completion), in order to display the sub-planning surface, It is necessary for the clerk to perform an operation of completing the product registration again (pressing the subtotal key). That is, after additional registration of a product, the sub-planning plane is displayed when both the sub-total key is pressed again by the clerk and the registration completion key is pressed by the customer. Note that, instead of the above, the operation of completing the product registration again on the clerk side may be unnecessary. In other words, after additional registration of a product, the sub-planning plane may be displayed if the clerk does not press the subtotal key again but presses the registration completion key on the customer side.

  After the subtotal key is pressed and before the registration completion key is pressed, the clerk may additionally register the customer's product as described above. Good. After the subtotal key is pressed and before the registration completion key is pressed, the store clerk's display unit 210 declares whether the customer's product is to be additionally registered or the customer's product is to be registered ( Specified). For example, a declaration may be made using a button or the like displayed on the clerk-side display unit 210.

  In the double scan mode, when the same product is scanned on the customer side and the clerk side, it may be notified that the same product has been scanned on the customer side and the clerk side. For example, a message such as "The same product has been scanned" or "It is the second scan" may be displayed on the display unit. The display destination of the message may be at least the clerk. In other words, when the same product is scanned on both the customer side and the clerk side, a message is always displayed on the clerk side display unit 210, but a 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 on the customer side, a message is displayed on the clerk display unit 210, and the same product as the product already scanned on the clerk side is displayed on the customer side. When scanning is performed, 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 controlled whether or not to display the above-mentioned message on the customer-side display unit 205 in accordance with a setting operation (or a switching operation) by a clerk.

  In the above description, in the double scan mode, during registration of a product (registration screen), the salesclerk side display unit 210 displays the product registered on its own side (clerk side) and the product registered on the other side (customer side). Are displayed in different display modes, and the customer side display unit 205 displays the product registered on the customer side (customer side) and the product registered on the other side (clerk side) in different display modes. The display mode on the side display unit 210 and the customer side display unit 205 is not limited to this.

  For example, the salesclerk side display unit 210 does not display the product registered on the other side (customer side), but displays the product registered on its own side (clerk side). ) May be displayed instead of displaying the product registered in (1). Alternatively, the clerk-side display unit 210 displays in a different display form a product registered on its own side (the clerk side) and a product registered on the other side (the customer 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 does not display the product registered on the other side (customer side), but displays the product registered on its own side (clerk side), and the customer side display unit 205 displays the product registered on its own side (customer side). ) And the product registered on the other side (clerk side) may be displayed in different display modes.

  It should be noted that the clerk-side display unit 210 may be able to declare (designate) whether to display (or not) the merchandise registered on the other side (customer side) on its own side (the clerk-side display unit 210). Good. Instead of or in addition to the above, the clerk-side display unit 210 declares whether or not the merchandise registered on its own side (the clerk side) is to be displayed (or not) on the other side (the customer-side display unit 205) ( Specified). In addition, instead of or in addition to the above, the customer-side display unit 205 declares whether (or not) the merchandise registered on the partner side (the clerk side) to be displayed on the user side (the customer-side display unit 205). (Designation). In any case, the declaration may be made by a button or the like displayed on the screen.

  In addition, during product registration, the product registered by the user and the product registered by the other party are displayed in different display areas, and after the product is registered, the product registered by the user and the product registered by the other party are displayed. The registered products may be displayed in a common display area. In other words, for example, when a transition is made from the registration screen to the sub-planning plane by pressing the subtotal key or the like, the product registered on the own side and registered on the other side and displayed in different display areas on the registration screen before pressing the subtotal key or the like are registered The displayed product may be displayed in the common display area on the sub-planning plane after the subtotal key or the like is pressed.

In the clerk-side display unit 210, regarding the display mode of the clerk-side display unit 210 and the customer-side display unit 205 during the registration of the product and after the registration of the product, the product registered on the own side and the registered product on the other side are registered. It may be possible to declare (designate) whether the displayed product is displayed in a different display area or in a common display area. Alternatively or in addition to the above, regarding the display mode during or after product registration on the customer side display unit 205, the product registered on the customer side and the partner side may be displayed. It may be possible to declare (designate) whether to display the registered product in a different display area or in a common display area. In any case, the declaration may be made by a button or the like displayed on the screen.
(Switching operation mode, etc.)
When switching the operation mode, the POS terminal 20 may display a message indicating that the operation mode is switched on at least one of the customer-side display unit 205 and 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), the customer-side display unit 205 displays "Switch to accounting-only mode" for a predetermined time (for example, about several seconds). A message may be displayed. After switching the operation mode, a message indicating that the operation mode has been switched may be displayed.

  Note that 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 the full self mode in which the clerk is not logged in. The determination may be made according to the operation of the clerk (for example, button operation).

  In other words, in the full self mode in which the clerk is not logged in, when the clerk logs in, the POS terminal 20 switches to the button for maintaining the full self mode, the button for switching to the normal mode, and the double scan mode. A button for switching may be displayed, and the operation mode after login may be controlled according to which button has been operated. For example, if support for leaving all of the product registration to the store clerk is requested (when the store clerk is called), the store clerk operates a button for switching to the normal mode after login, and registers the product. After that, if you ask for support to leave a part to the clerk (to register the customer himself but also want the clerk to cooperate), if the clerk is called, the clerk double-scans after logging in The user operates the button for switching to the mode and logs in for some reason (for example, checking the processing status), but the customer himself wants to register himself or does not need the assistance of a clerk (or temporarily (If the customer cannot log in and cannot support the customer), the clerk operates the button for maintaining the full self mode after logging in. In the case where the full self mode is maintained after the clerk logs in, the name of the product registered by the customer may not be displayed on the clerk side display unit 210 from the viewpoint of privacy and the like. However, information that does not significantly affect privacy or the like (total amount of money during registration) may be displayed. By displaying the total amount of money during registration, the clerk can appropriately confirm the right to the lottery (whether or not the purchase amount exceeds a predetermined amount, for example), and thus can prepare for the lottery in advance.

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

  The login state of the POS terminal 20 is canceled based on an explicit operation (logout operation) by the clerk (from the login state to the logout state). In place of or in addition to the explicit operation of the clerk, if a predetermined time (for example, setting can be performed for each terminal) has elapsed since the last operation by the clerk (if no operation has been performed for the predetermined time), the login state is canceled. May be performed.

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

  However, for products that require the intervention of a clerk (for example, products that require heating in a range, products that are taken out by a clerk (meatballs, tobacco, etc.)), it is necessary to inform the clerk of the product, regardless of the above settings. May be displayed on the clerk-side display unit 210. In addition, since it is necessary to notify a clerk of a product (for example, tobacco, liquor, and the like) that requires age authentication, it may be displayed on the clerk-side display unit 210 regardless of the setting. Whether or not the product requires the intervention of a clerk may be determined in advance for each product.

(About printing department)
In the above description, the POS terminal 20 is provided with one printing unit 213 that can rotate freely from the clerk side to the customer side and from the customer side to the clerk side (the direction of the medium issuing port). Two printing units having an issuing port may be provided. In other words, the POS terminal 20 has a clerk-side printing unit having a medium issuing port on the clerk side and a media issuing port on the customer side instead of one printing unit 213 capable of freely changing the direction of the medium issuing port. A certain customer-side printing unit may be provided separately.

(About the scanner section)
In the above description, the customer-side scanner unit 206 is of a type that an operator (a clerk or a customer) holds in his hand and recognizes identification information by approaching an object (such as a product), but is of another type. There may be. For example, it may be a fixed type in which the object is recognized closer to the object. The same applies to the clerk-side scanner unit 212.

(About analysis etc.)
In the POS system 1, an electronic journal may be stored and used for various analyses. 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 stores the operation status of each operation mode (for example, by time of day, by person in charge, or unconditionally by each mode). Operating time, etc.) and the registration status of the clerk and the customer in the double scan mode (the ratio of the number of product registrations between the clerk and the customer, etc. It may be different for each clerk, or the attribute of the customer (male and gender) based on the member number, etc. Or the like, if it can be grasped, etc.). The analysis result may be output to a list or the like.

  In addition, the electronic journal stores, for example, the registration start time (in seconds) of the first product in each transaction and the display start time of the small planning plane, and stores the information by operation mode (for example, by operation mode, purchase points, etc.). ) (For example, the time required until the registration process is completed (until the start of the small plan plane display), etc.) may be analyzed.

(About other indications)
Further, the POS terminal 20 may display, for example, information about an error or the like (for example, a warning about change, a warning about paper, information about calling a clerk, and the like). Further, by transmitting and receiving information via the LAN 11, information regarding another POS terminal 20 may be displayed instead of or in addition to the information regarding the POS terminal 20. In addition, when information related to another POS terminal 20 is displayed, a display according to the position of the other POS terminal 20 (the positional relationship with the POS terminal 20) may be performed.

  Each POS terminal 20 refers to information indicating a positional relationship with another POS terminal 20 (for example, each POS terminal 20 may store and refer to information indicating the positional relationship, The store controller 10 stores the information indicating the positional relationship, and each POS terminal 20 may access the store controller 10 and refer to the information indicating the positional relationship.) 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 terminal 20. As an example, the first POS terminal 20-1 is disposed 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 disposed on the right side (right side when viewed from the clerk side) of the second POS terminal 20-2. -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 on the left and right center, and on the right side In the case where the third POS terminal 20-3 is arranged), the first POS located on the left side of the second POS terminal 20-2 in the clerk-side display unit 210 of the second POS terminal 20-2 arranged at the left and right center. Information on the terminal 20-1 may be displayed on the left side of the screen, and information on 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.

  Also, 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, information about the third POS terminal 20-3 located farther from the first POS terminal 20-1 is located on the right side than 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 disposed on the right side, the first POS terminal 20-1 and the second POS terminal 20-2 located on the left side of the third POS terminal 20-3. 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 on the left side than 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 in a case where three POS terminals 20 are arranged in the store, but the same applies to a case where two or four or more POS terminals 20 are provided. In the above description, the current operation mode of the own POS terminal 20 is notified (displayed). For example, by acquiring information on the operation mode of another POS terminal 20 via the LAN 11, the other POS terminal 20 is notified. The 20 current operation modes may also be notified (displayed).
