FIGS. 8B and 8C are diagrams in the semi-self mode. 5 is a flowchart showing a basic flow of operation of the POS terminal 20.

  In the following description, as a different viewpoint from the above-described four operation mode classifications, the mode in which the POS terminal 20 executes the product registration process is the registration mode, and the mode in which the settlement process is executed is the accounting mode (or settlement). Mode).

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

  In the normal mode, the store clerk registers the customer's purchased products on the store clerk side (store clerk side scanner unit 212, store clerk side display unit 210, key operation unit 211). In other words, the POS terminal 20 executes a process for registering purchased products by the operation of the store clerk (operation of the store clerk side scanner unit 212, the store clerk side display unit 210, the key operation unit 211, etc.) (upper part of FIG. 5A). .

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

  That is, in the normal mode, as shown in FIG. 5B, first, on the clerk side, for example, the merchandise is scanned by the clerk-side scanner unit 212 (step S10: YES), and the merchandise is registered (step S11). After depressing a subtotal key (for example, a subtotal key displayed on the store clerk side display unit 210 or a subtotal key arranged on the key operation unit 211) (step S30: YES), on the customer side, for example, a change machine 209 Is settled (step S50), and the process is completed.

  The customer may be on standby until the registration process by the store clerk is completed (until the total amount is confirmed), but money may be put into the change machine 209 before the registration process is completed. That is, the POS terminal 20 can accept payment during the registration process (upper part of FIG. 5A).

  Further, the store clerk may be on standby until the customer completes payment (until the customer takes a change or receipt), but may register a product purchased by the next customer. That is, the POS terminal 20 can register the purchased product of the next customer during the checkout process (the lower part of FIG. 5A). Further, the store clerk may be absent during the checkout by the customer (lower part of FIG. 5A). That is, during the customer's checkout, the customer's response may be finished.

  In addition, the POS terminal 20 controls the change / dispensing of the change / pick by the change machine 209 in order to prevent forgetting to change the change when there is change, and a sensor or the like indicates that the customer has removed the change / pipe. The receipt of the receipt by the printing unit 213 is controlled. The same applies to other operation modes. As described above, in the normal mode (the same applies to the double scan mode), there may or may not be a clerk in front of the customer who receives the change. However, if there is a clerk, the above-described control is not necessarily performed. (In other words, the change and change of the bills and the receipt may be issued at the same time, or the receipt may be issued first). Further, according to the current operation mode and the presence / absence of a store clerk (for example, the presence / absence of a store clerk is recognized by a sensor), the timing of paying out change / fishing bills and issuing a receipt may be controlled.

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

  In the full self mode, the customer registers the purchased product on the customer side (customer side scanner unit 206, customer side display unit 205). In other words, the POS terminal 20 performs a purchase product registration process by a customer operation or the like (scanning by the customer side scanner unit 206, touching the customer side display unit 205) (upper part of FIG. 6A).

  When the registration process is completed, the customer confirms the total amount of the purchased product on the customer side display unit 205, inserts money into the change machine 209, or operates the card settlement unit 208 to settle it (FIG. 6 (A ) Bottom). That is, the POS terminal 20 executes the settlement process by the customer's operation or the like (insertion of money into the change machine 209, operation of the card settlement unit 208) (lower part of FIG. 6A).

  That is, in the full self mode, as shown in FIG. 6 (B), on the customer side, for example, the customer side scan unit 206 scans the product (step S20: YES) and registers the product (step S21). After the registration completion key (for example, the registration completion key displayed on the customer side display unit 205) is pressed (step S40: YES), the customer side, for example, checks out by the change machine 209 (step S50), and processing Is completed.

  In the full self mode, as described above, the registration process and the settlement process are executed on the customer side, but the store clerk cannot do anything. That is, even when the POS terminal 20 is operating in the full self mode, the store clerk side scanner unit 212 can scan the store clerk code. Further, even when the POS terminal 20 is operating in the full self mode, it is possible to display various information (for example, a list described in FIG. 15) on the clerk-side display unit 210.

(Double scan mode)
As shown in FIG. 7A, the double scan mode is an operation mode in which registration processing is executed on both sides of the store clerk side and the customer side, and settlement processing is executed on the customer side. That is, as shown in FIG. 7B, in the double scan mode, both the store clerk side and the customer side are in the registration mode, and the customer side is in the accounting mode. That is, the POS terminal 20 operates as a registration accounting mode when viewed through the registration process to the settlement process.

  In the double scan mode, the store clerk registers the purchased product on the store clerk side (store clerk side scanner unit 212, store clerk side display unit 210, key operation unit 211), and the customer purchases the purchased product on the customer side (customer side scanner unit). 206, registration on the customer side display unit 205). That is, the POS terminal 20 is operated by a store clerk (scanning by the store clerk side scanner unit 212, touching the store clerk side display unit 210, pressing the key operation unit 211, etc.), and a customer operation (customer side scanner unit 206). , Scanning of the customer-side display unit 205), the purchase product registration process is executed (upper part of FIG. 7A).

  When the registration process is completed, the customer confirms the total price of the purchased product on the customer side display unit 205, inserts money into the change machine 209, or operates the card settlement unit 208 to settle it (FIG. 7 (A ) Bottom). That is, the POS terminal 20 executes the settlement process by the customer's operation or the like (insertion of money into the change machine 209, operation of the card settlement unit 208) (lower part of FIG. 7A).

  That is, in the double scan mode, products are first registered on the clerk side and the customer side. For example, as shown in FIG. 7B, the merchandise side scanner unit 212 scans (step S10: YES), the product is registered (step S11), and the customer side scanner unit 206 scans (step S20: YES), the product is registered (step S21). Subtotal key (for example, a subtotal key displayed on the store clerk side display unit 210 or a subtotal key arranged on the key operation unit 211), or a registration completion key (for example, registration displayed on the customer side display unit 205) After the press of the completion key or the like (step S41: YES), payment is performed by the change machine 209, for example, on the customer side (step S50), and the process is completed.

  The store clerk may be on standby until payment by the customer is completed (until the customer receives a change or a receipt), but may register a product purchased by the next customer. That is, the POS terminal 20 can register the purchased product of the next customer during the checkout process (the lower part of FIG. 7A). Further, the store clerk may be absent during the checkout by the customer (the lower part of FIG. 7A). That is, during the customer's checkout, the customer's response may be finished.

(Semi-self mode)
The semi-self mode is an operation mode by two or more POS terminals 20, and as shown in FIG. 8A, a clerk of at least one POS terminal 20 (first POS terminal 20-1 in the example of FIG. 8). The registration process is executed on the customer side, and the settlement process is performed on the customer side of the other POS terminal 20 (one of the second POS terminal 20-2 and the third POS terminal 20-3 in the example of FIG. 8). The operation mode to execute. That is, in the semi-self mode, one or more devices (one device of the first POS terminal 20-1 as shown in FIG. 8B in the example of FIG. 8) enters the registration-only mode, and one or more devices (FIG. 8). In this example, as shown in FIG. 8C, the second POS terminal 20-2 and the third POS terminal 20-3 are in the accounting-only mode.

  In the case of the semi-self mode, the clerk registers the customer's purchased product on the clerk side (the clerk side scanner unit 212, the clerk side display unit 210, and the key operation unit 211) at the POS terminal 20 in the registration-only mode. In other words, the POS terminal 20 executes a process for registering purchased products by the operation of the store clerk (operation of the store clerk side scanner unit 212, the store clerk side display unit 210, the key operation unit 211, etc.) (upper part of FIG. 8A). .

  When the registration process by the clerk is completed, the customer moves to the POS terminal 20 in the accounting-only mode, confirms the total price of the purchased product on the clerk-side display unit 210, inserts money into the change machine 209, or pays by card. The unit 208 is operated and settled (lower part of FIG. 8A). That is, the POS terminal 20 executes the settlement process by the customer's operation or the like (insertion of money into the change machine 209, operation of the card settlement unit 208) (lower part of FIG. 8A).

  When the registration process is completed at the POS terminal 20 in the registration-only mode (first POS terminal 20-1 in the example of FIG. 8), the customer changes from the POS terminal 20 in the registration-only mode to the POS terminal 20 (in FIG. 8). In the example, the information is moved to the second POS terminal 20-2), but information necessary for the settlement process (registration information generated in the first POS terminal 20-1 in the registration-only mode) is stored in the destination POS terminal 20. Supplied.

  The destination POS terminal 20 (the POS terminal 20 that executes the settlement process among the POS terminals 20 in the accounting-only mode) may be specified in the POS terminal 20 in the registration-only mode. Alternatively, the registration-only mode POS terminal 20 issues a medium (a medium on which a bar code or the like for obtaining information necessary for the checkout process is printed), and the accounting-only mode POS terminal 20 is read. The destination POS terminal 20 may be used.

  That is, in the semi-self mode, first, merchandise is registered on the clerk side of the POS terminal 20 (first POS terminal 20-1) in the registration-only mode. For example, as shown in FIG. 8B, the merchandise is registered (step S11) by scanning with the clerk-side scanner unit 212 (step S10: YES). After pressing a subtotal key (for example, a subtotal key displayed on the store clerk side display unit 210 or a subtotal key arranged on the key operation unit 211) (step S30: YES), for example, the POS terminal 20 in the accounting-only mode ( When one of the second POS terminal 20-2 and the third POS terminal 20-3) is designated (step S31: YES), registration information is transmitted to the designated POS terminal 20 (step S32), and the registration-only mode The processing at the POS terminal 20 is completed.

  Subsequently, as shown in FIG. 8C, after receiving the registration information (step S49: YES), the accounting-only mode POS terminal 20 (that is, the POS terminal 20 designated by the registration-only mode POS terminal 20). Is settled on the customer side, for example, by the change machine 209 (step S50), and the processing at the POS terminal 20 in the accounting-only mode is completed.

  After the registration information is transmitted, the store clerk can register the purchased product of the next customer (the lower part of FIG. 8A). Further, the store clerk may be absent after transmitting the registration information (lower part of FIG. 8A). Further, the registration-only mode may not be provided. That is, it is only necessary that the registration information can be designated to other POS terminals 20 in the normal mode as in the registration-only mode. There is no need to disable the transmission function in the normal mode. In this case, in the normal mode, as described above, the registration process is executed on the clerk side, and the settlement process is executed on the customer side of the terminal using the registration information generated in the registration process (see FIG. 5). ), A registration process is executed on the store clerk side, and the registration information generated in the registration process is transmitted to another terminal (another terminal capable of executing the settlement process, eg, another POS terminal 20) (via the LAN 11). The process of transmitting directly to the other terminal, or transmitting to the other terminal via the store controller 10 or the monitoring terminal (not shown), the same applies hereinafter), the registration information generated in the registration process, etc. (Bar code, two-dimensional code, etc.) can be printed on a medium and issued as a bill. That is, the POS terminal 20 in the normal mode has a function of registering a product in the own terminal and registering the product in another terminal in addition to a function of registering the product in the own terminal and paying out in the own terminal. In addition, the POS terminal 20 in the normal mode has a function of registering products in the own terminal and paying out in other terminals, like the POS terminal 20 in the semi-self mode (registration-only mode), but the POS terminal 20 in the full self mode. (The same applies to the POS terminal 20 in the normal mode), like the POS terminal 20 in the semi-self mode (accounting-only mode), may have a function of paying out products registered in other terminals. That is, the POS terminal 20 in the full self mode and the POS terminal 20 in the normal mode receive the registration information from other terminals (such as the POS terminal 20 in the semi-self mode (registration only mode), the normal mode POS terminal 20, etc.). The bills may be read) and the checkout process may be executed.

The POS terminal 20 notifies the current operation mode. For example, the current operation mode may be displayed on the clerk side display unit 210. Specifically, a screen having an operation mode display field may be displayed on the clerk-side display unit 210, and the current operation mode may be displayed in the operation mode display field on the screen. In addition, a screen on which images corresponding to each operation mode (for example, a button-like image) 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. You may display in the display mode (For example, the display mode conspicuous rather than the display mode of another image) different from the image which does not respond | correspond. The operation mode may be displayed on the customer display unit 205 in the same manner.

  Further, the POS terminal 20 may notify information according to the current operation mode. For example, the customer display unit 205 may display a message corresponding to the current operation mode. Specifically, when the current operation mode is full self mode, for example, when waiting, the customer himself registers the product (message such as “I ask the customer to scan”) You may display on the customer side display part 205 (for example, scroll display with a big character).

(Operation mode transition)
Next, the transition (switching) of the operation mode of the POS terminal 20 will be described. The operation mode of the POS terminal 20 is changed according to an explicit mode change operation (an input on an operation mode setting screen, an operation of an operation mode setting button, or the like) by a store clerk. The operation mode is switched by switching means in the CPU 201. Further, the operation mode of the POS terminal 20 is shifted according to an operation other than the explicit mode shift operation by the store clerk (for example, reading of the store clerk code). In addition, the POS terminal 20 has predetermined conditions (such as elapsed time and predetermined time (schedule)) that do not depend on store clerk operations, conditions related to transmission / reception of information such as commands with other terminals, etc. ) To shift the operation mode.

  9 and 10 are diagrams illustrating an example of operation mode transition. FIG. 9A is a flowchart showing a flow of transition from the normal mode to the full self mode. FIG. 9B is a flowchart showing a flow of transition from the full self mode to the double scan mode. FIG. 10A is a flowchart showing a flow of transition from the normal mode to the semi-self mode (registration-only mode). FIG. 10B is a flowchart showing a flow of transition from the normal mode to the semi-self mode (accounting-only mode).

(Transition from normal mode to full self mode)
The flowchart in FIG. 9A starts when the POS terminal 20 (normal mode) is not in use (that is, starts when neither the store clerk nor the customer uses it).

Step S100: Start counting the non-use time.
Step S101: It is determined whether use is started by a store clerk or a customer. If use has not started, the process proceeds to step S102. When the use is started, the process proceeds to step S104.

Step S102: It is determined whether or not a non-use time has passed a predetermined time (for example, a preset 10 minutes). If the predetermined time has elapsed, the process proceeds to step S103. If the predetermined time has not elapsed, the process returns to step S101.
Step S103: The operation mode is shifted from the normal mode to the full self mode.
Step S104: Ending the measurement of the non-use time. Then, the flowchart of FIG. 9A ends.

  In addition, when shifting to the full self mode, the store clerk may be notified of the transition to the full self mode (for example, sending information indicating that there is an undelivered product to the terminal carried by the store clerk). . Further, when the mode is shifted to the full self mode, a message for instructing or requesting the customer to perform self-registration may be displayed on the customer side display unit 205.

  FIG. 9A shows a flow relating to the transition from the normal mode to the full self mode, but the transition from the double scan mode to the full self mode is the same as the flow in FIG. 9A. It may be.

(Transition from full self mode to double scan mode)
The flowchart of FIG. 9B starts at all times (periodically at very short time intervals) in the POS terminal 20 (full self mode).

Step S110: It is determined whether or not the clerk code has been read by the clerk side scanner unit 212. If the clerk code has been read, the process proceeds to step S111. If the clerk code has not been read, the flowchart of FIG. 9B ends.

Step S111: The operation mode is shifted from the full self mode to the double scan mode. Then, the flowchart of FIG. 9B ends.

(Transition from normal mode to semi-self mode (registration-only mode))
The flowchart of FIG. 10A starts at all times (periodically at very short time intervals) in the POS terminal 20 (normal mode).

Step S120: It is determined whether or not there has been an operation for declaring the transition to the semi-self mode (registration-only mode). For example, a button for declaring the transition to the semi-self mode (registration-only mode) may be displayed on the clerk-side display unit 210, and it may be determined whether or not the button has been pressed (touched). If there is an operation, the process proceeds to step S121. If there is no operation, the flowchart of FIG.

Step S121: It is determined whether there is another POS terminal 20 operating in the semi-self mode in the POS system 1. As described above, in the case of the semi-self mode, since at least one POS terminal 20 in the registration-only mode and one POS terminal 20 in the accounting-only mode are required, for example, the POS terminal 20 is the first POS terminal 20-1. In this case, it is determined whether one of the second POS terminal 20-2 and the third POS terminal 20-3 operates in the semi-self mode (registration-only mode) and the other operates in the semi-self mode (accounting-only mode). . If there is no other POS terminal 20 operating in the semi-self mode, the process proceeds to step S122.
If there is another POS terminal 20 operating in the semi-self mode, the process proceeds to step S124.

Step S122: It is determined whether another POS terminal 20 to be shifted to the semi-self mode (accounting only mode) has been designated. If so, the process proceeds to step S123. If there is no designation, the process of step S122 is repeated.
Step S123: An instruction to shift to the semi-self mode (accounting only mode) is transmitted to the other designated POS terminal 20.

Step S124: It is determined whether processing is in progress. If not, the process proceeds to step S125. If it is being processed, the process of step S124 is repeated.
Step S125: The operation mode is changed from the normal mode to the semi-self mode (registration only mode). Then, the flowchart of FIG.

  The operation in step S120 is performed when there is no other POS terminal 20 that is already operating in the semi-self mode and there is no other POS terminal 20 that can be shifted in the semi-self mode. It is better not to be able to do it.

(Transition from normal mode to semi-self mode (accounting only mode))
The flowchart of FIG. 10B starts at all times (periodically at very short time intervals) in the POS terminal 20 (normal mode).

Step S130: It is determined whether or not an instruction to shift to the semi-self mode (accounting only mode) has been received. If a migration instruction has been received, the process proceeds to step S131. If the transfer instruction has not been received, the flowchart of FIG. 10B ends.

Step S131: It is determined whether processing is in progress. If not, the process proceeds to step S132. If it is in process, the process of step S131 is repeated.
Step S132: The operation mode is changed from the normal mode to the semi-self mode (accounting only mode). Then, the flowchart of FIG. 10B ends.

  FIG. 10B shows a flow relating to the transition from the normal mode to the semi-self mode (accounting-only mode), but the transition from the full self-mode to the semi-self mode (accounting-only mode) is also illustrated. It may be the same as the flow of 10 (B). In addition, in the full self mode, if the registration information to be processed by the own device is detected in the full self mode, the transaction is immediately switched to the accounting-only mode if it is on standby, and the transaction is performed if another customer is performing a transaction operation. You may switch to the accounting-only mode after the end. That is, the migration instruction can be determined based on detection (reception) of registration information. Furthermore, the transfer instruction may be issued by operating other information terminals such as a mobile terminal such as a smartphone possessed by a store clerk and a mobile terminal used for inventory of store display products.

(Display in full self mode)
Next, display on the POS terminal 20 when in the full self mode will be described with reference to FIGS. 11 and 12. 11 and 12 are display examples on the POS terminal 20 in the full self mode.

  FIG. 11A is a display example of a registration start screen displayed on the customer side display unit 205 of the POS terminal 20 in the full self mode. In FIG. 11A, a registration start button BT30 on the right side of the screen is a button for instructing start of product registration. The customer performs an operation (for example, a touch operation) on the registration start button BT30 before starting the product registration. Buttons BT35 to BT37 at the lower left of the screen are buttons for switching the display language to English, Chinese, and Korean, respectively. In the example shown in the figure, since Japanese is selected, a button for switching to English, Chinese, or Korean is displayed. For example, when English is selected, a registration start screen in English is displayed. Thus, a button for switching to Japanese, Chinese, or Korean will be displayed.

  When the customer operates the registration start button BT30, the POS terminal 20 shifts to the registration mode, and the display on the customer side display unit 205 shifts from the registration start screen to the registration screen.

  FIG. 11B is a display example of a registration screen displayed on the customer side display unit 205 of the POS terminal 20 in the full self mode. In the example shown in the figure, on the right side of the registration screen, the registered product name, unit price, the number of registered products (the number of purchases), and the total amount are displayed as registration contents. Here, the registration content of a scene where two items of merchandise (pears and apples) are registered is displayed. In addition, immediately after the registration start button BT30 is operated on the registration start screen shown in FIG. 11A and the registration screen is displayed, a registration screen in which no product has been registered yet (initial state registration screen). For convenience of explanation, FIG. 11B shows an example of a registration screen after a product has already been registered.

  The accounting button BT32 at the lower right of the screen is a button for instructing the end of product registration. When the customer operates the checkout button BT32 after completing the product registration, the POS terminal 20 shifts to the checkout mode and executes the checkout process. The salesclerk call button BT33 is a button for calling a salesclerk. The customer operates the store clerk call button BT33 when calling the store clerk (for example, when the store clerk needs support). When the customer operates the store clerk call button BT33, for example, a notification is given to the mobile terminal possessed by the store clerk, and sound is output from the mobile terminal or the mobile terminal vibrates. Further, when the customer operates the store clerk call button BT33, a predetermined lamp (indicator lamp such as a sign pole) installed in the store may be turned on.

  The buttons BT35 to BT37 are buttons for switching the display language to English, Chinese, and Korean, respectively, as described above. The “vegetable” button BT38 is a button for registering a product (vegetable in this case) without a barcode from a preset key. For example, when the customer operates the “vegetable” button BT38, a preset screen is displayed in which each vegetable can be registered by operating the preset key. In the illustrated example, only the “vegetable” button BT38 is illustrated, but the “vegetable” button BT38 is used as a button for registering any product such as meat, fresh fish, prepared dishes, bread, etc. from the preset key, not limited to vegetables. It can be displayed instead of or in addition. Note that. The preset key is set in advance at the POS terminal 20 by a store clerk or the like.

  When the customer operates the check button BT32, the POS terminal 20 shifts to the check mode, and the display on the customer side display unit 205 changes from the registration screen to the checkout screen.

  FIG. 12 is a display example of a settlement screen displayed on the customer side display unit 205 of the POS terminal 20 in the full self mode. FIG. 12A is a settlement screen (payment method selection screen) displayed when the settlement process is started. For example, the POS terminal 20 displays a payment method selection screen as shown in FIG. 12A when the checkout button BT32 is operated on the registration screen (see FIG. 13B). The payment method selection screen shown in the drawing displays the total amount of payment (here, 240 yen), payment method options, and the like. As payment method options, cash, credit, electronic money, and the like are displayed as selectable operation buttons.

  FIG. 12B is a settlement screen (payment screen) displayed when payment by cash is started. For example, when cash is selected on the payment method selection screen (see FIG. 12A), the POS terminal 20 displays a payment screen as shown in FIG. On the payment screen shown in the figure, an image showing where to put money is displayed on the left side of the screen, and the payment amount (240 yen in this case), the amount of money (deposited amount), etc. are displayed on the right side of the screen. Is done. FIG. 12C shows a settlement screen (payment determination screen) displayed when the deposit amount is determined. For example, the POS terminal 20 displays a payment determination screen as shown in FIG. 12C when cash (deposit) equal to or greater than the payment amount (purchase amount) is inserted. In the payment determination screen shown in the figure, the payment amount (240 yen in this case), the amount of money (deposited amount, 250 yen here), fishing (10 yen here), etc. are displayed on the right side of the screen. On the left side of the screen, a guide for determining the amount to be deposited (here, “If you like, press the end button”) is displayed. The end (receipt) button BT40 is a button operated by the customer when determining the deposit amount. When the customer operates the end (receipt) button BT40, the POS terminal 20 executes the settlement process based on the payment amount (here, 240 yen) and the deposit amount (here, 250 yen).

  FIG. 12D is a settlement screen (change screen) displayed when changing is released. For example, when the end (receipt) button BT40 is operated on the payment determination screen (FIG. 12C), the POS terminal 20 displays a change screen as shown in FIG. In the change screen shown in the figure, an image prompting receipt of change is displayed on the left side of the screen, and the payment amount (240 yen in this case) and the input amount (deposit amount. 250 here) are continued on the right side of the screen. Yen), fishing (here, 10 yen), etc. are displayed.

  FIG. 12E is a payment screen (receipt screen) displayed when the change is removed. For example, when the change is removed from the outlet of the change machine 209, the POS terminal 20 displays a receipt screen as shown in FIG. Note that the POS terminal 20 may determine that the change has been removed when a sensor such as a photosensor is installed in the vicinity of the outlet, and the sensor recognizes an object (assuming a customer's hand). Furthermore, after detecting that the change has been removed, a receipt or a receipt may be printed to prevent the change from being forgotten.

  FIG. 12F is a pause screen displayed when the POS terminal 20 is in a pause state. That is, the POS terminal 20 is in the sleep mode (pause state), but displays the pause screen as shown in FIG.

  The POS terminal 20 displays a registration start screen (FIG. 11A) after displaying the receipt screen (FIG. 12E). For example, the POS terminal 20 displays a registration start screen after the receipt is removed from the issue port of the printing unit 213. The POS terminal 20 may include a sensor that can recognize that the receipt has been removed from the issuing port.

  If the change amount is equal to the deposit amount and no change is generated, the change screen (FIG. 12D) is not displayed and the receipt screen (FIG. 12E) is displayed from the payment screen (FIG. 12C). )).

  As described above, in the full self mode, when a customer registers and settles a product to be purchased, the POS terminal 20 displays the registration start screen and the registration screen shown in FIGS. 11 and 12 according to the progress and situation of the operation. Then, a payment screen is displayed on the customer display unit 205. The POS terminal 20 also displays the same display content as the display content displayed on the customer display unit 205 on the store clerk display unit 210. For example, the POS terminal 20 displays the same screen as that on the customer display unit 205 on the store clerk display unit 210 (so-called mirror display or mirroring display). Note that displaying similar display contents is not limited to displaying exactly the same screen, and includes that some display contents and layouts are different. For example, if it is a registration screen, the contents essential for the registration operation (for example, the name of the registered product, the unit price, the number of registered products (the number of purchases) in FIG. 11B, the total price, “vegetable” ”Button BT38, checkout button BT32, etc.) may be included in displaying the same display contents even if at least some of the other display contents are different. .

(Recall registered information in semi-self mode)
In the semi-self mode, when the registration process is performed at the POS terminal 20, for example, the first POS terminal 20-1, and the settlement process is performed at the designated POS terminal 20, for example, the second POS terminal 20-2, the first POS terminal 20 is used. -1 to the second POS terminal 20-2. In the semi-self mode, the registration information transmitted from the first POS terminal 20-1 to the second POS terminal 20-2 can be recalled to the first POS terminal 20-1. Recalling registration information refers to holding the checkout process to be executed by the POS terminal (second POS terminal 20-2) based on the registration information after transmitting the registration information to the POS terminal (second POS terminal 20-2), or It is to cancel and return the transmitted registration information to the POS terminal (first POS terminal 20-1). The recall generally corresponds to the case where the registered information is corrected, for example, when the product registered by the POS terminal (first POS terminal 20-1) is canceled or when the product is additionally registered for purchase. Done. Specifically, correction of registration information and the like includes addition of a product, correction of quantity, deletion or discount operation by a privilege, input of member identification information, and the like.

  Recalling registration information is, for example, when you find that a customer has forgotten their wallet in a car after completing the registration process, or when returning to the wallet or searching for a family with insufficient money Etc. are also performed. After the call back operation, the second POS terminal 20-2 can execute another operation. Further, the operation may be suspended, and the corrected registration information may be received again to perform the settlement process. In the first POS terminal 20-1, it is also possible to place the recalled registration information on hold and register other customers' products.

(Display of salesclerk display section 210 in first POS terminal 20-1)
Hereinafter, the display on the clerk-side display unit 210 in the POS terminal 20 (first POS terminal 20-1) when registering information, transmitting registration information, and recalling the transmitted registration information will be described with reference to FIGS. To do. 13 and 14 are display examples of the clerk side display unit in the first POS terminal 20-1. In the description of FIGS. 13 and 14, it is assumed that the first POS terminal 20-1 is in a semi-self mode registration-only mode, and the second POS terminal 20-2 is in a semi-self mode accounting-only mode. Further, it is assumed that the third POS terminal 20-3 is in the full self mode. In addition, it is assumed that registration processing is performed in the first POS terminal 20-1, and settlement processing is performed in the second POS terminal 20-2. In addition, after the registration information is called back by the first POS terminal 20-1, the first POS terminal 20-1 shifts to the normal mode, and the first POS terminal 20-1 performs the settlement process. The second POS terminal 20-2 shifts to the full self mode. The second POS terminal 20-2 detects the return of registration information (sent to the first POS terminal 20-1), and shifts to the full self mode when detecting the return of registration information.

  FIG. 13 is a display example on the registration screen displayed on the clerk side display unit 210 of the first POS terminal 20-1. Specifically, FIG. 13 shows display contents of a registration screen in a scene where two items of merchandise (aspara) are registered. For example, the registration screen is displayed after the store clerk reads a barcode (product code or the like) attached to the product and the registration process is started.

  On the registration screen, a sheet (product registration sheet) indicating the product registration content corresponding to each transaction is displayed. A tab (region) (product registration tab (region): an example of a heading region) is attached to the product registration sheet. In FIG. 13, one product registration tab (area) TAB-1 is displayed. In the product registration tab (area) TAB-1, a symbol of an arbitrary animal (here, “cat”) is displayed.

  In FIG. 13, an image GA01 in the lower left of the product registration sheet with the product registration tab (area) TAB-1 of “Cat” shows the state of the No. 2 register (second POS terminal 20-2 in FIG. 1). . An image GA02 in the lower left of the product registration sheet shows the state of the No. 3 register (the third POS terminal 20-3 in FIG. 1).

  The subtotal button BT10 at the lower right of the product registration sheet is a button for instructing the end of product registration. The store clerk operates (touches) the subtotal button BT10 after the product registration is completed. The pause button BT11 is a button for pausing the own terminal (first POS terminal 20-1). The store clerk operates the pause button BT11 when leaving the terminal (for example, when searching for a product or not using the product for a while).

  FIG. 14 is a display example on the small plan surface displayed on the clerk side display unit 210 of the first POS terminal 20-1. Specifically, FIG. 14 shows the display content of the small plan surface in the scene (scene after operation of the subtotal button BT10) following the scene of FIG.

  In FIG. 14, a current total button BT20 is a button having the same function as the end (receipt) button BT40 to be pressed after the customer deposits the change bill machine. When the customer is confused about the operation at the timing of pressing the end (receipt) button BT40, the store clerk presses the current button BT20 on behalf of the customer, so that the end (receipt) button BT40 is operated. For example, a change is paid out from a change bill machine or a receipt is issued.

  The first register button BT21 is a button for designating a No. 2 register (second POS terminal 20-2 in FIG. 1). The store clerk operates the first register button BT21 when the second POS terminal 20-2 is designated as a terminal for executing the settlement process. In addition, the display of “(checkout)” shown on the first register button BT21 indicates that the operation mode of the terminal (second POS terminal 20-2) corresponding to the first register button BT21 is the checkout mode of the semi-self mode. It is a representation.

  When the operation of the first register button BT21 is accepted, the first POS terminal 20-1 transmits registration information to the No. 2 register (second POS terminal 20-2).

  The second cash register button BT22 is a button for designating a No. 3 cash register (the third POS terminal 20-3 in FIG. 1). The store clerk operates the second register button BT22 when designating the third POS terminal 20-3 as a terminal for executing the settlement process. Note that “(full)” indicated in the second register button BT22 indicates that the operation mode of the terminal (third POS terminal 20-3) corresponding to the second register button BT22 is the full self mode. is there. Further, the broken line of the second register button BT22 indicates that the button (second register button BT22) is displayed in a display mode (for example, gray down) indicating that the operation of the button (second register button BT22) is not effective.

  In the example shown in FIG. 14, the operation of the second register button BT22 is not valid, but if the operation of the second register button BT22 is valid and the operation of the second register button BT22 is accepted, The first POS terminal 20-1 transmits registration information to the No. 3 cash register (third POS terminal 20-3). By operating the first register button BT21 and transmitting the registration information to the second POS terminal 20-2, the registration process for one transaction in the first POS terminal 20-1 is completed. In addition, the transmission button is always displayed during product registration, and other device statuses are displayed. Therefore, the selection of the device for the settlement process can be designated flexibly according to the situation. In FIG. 14, the display positions of the first registration button BT21 and the second registration button BT22 are different from the display positions of the image GA01 and the image GA02. However, the display of the image GA01 and the image GA02 is performed without changing the display position. The first registration button BT21 and the second registration button BT22 may be displayed at the positions, respectively.

  The check ticket button BT25 is a button for causing the printing unit 113 to issue a check ticket. The store clerk operates the check ticket button BT25 when the POS terminal 20 that has read the check ticket is to execute the checkout process. By operating the check ticket button BT25, the registration process for one transaction in the first POS terminal 20-1 is completed.

  Information necessary for executing the checkout process is encoded and printed on the bill. For example, the registration information itself used for the checkout process may be printed as a QR code (registered trademark) on the check ticket, or information for specifying the registration information used for the checkout process (for example, transaction Identification information or the like) may be printed as a barcode.

  In the aspect of issuing the bill printed with the QR code, the POS terminal 20 (second POS terminal 20-2 or third POS terminal 20-3) that has read the bill (QR code) is, for example, The settlement process is executed using the registration information obtained from the QR code. Moreover, in the aspect which issues the bill which printed the said barcode, the POS terminal 20 (2nd POS terminal 20-2 or 3rd POS terminal 20-3) which read the said bill (barcode) is, for example, A registration information acquisition request including information (transaction identification information, etc.) for specifying registration information obtained from the barcode is sent to the terminal (first POS terminal 20-1) that issued the bill or the By transmitting the registration information from the terminal that issued the accounting ticket to the terminal that acquired the registration information (for example, the store controller 30), the registration information is received from the terminal that transmitted the registration information acquisition request, and the settlement process is executed. In other words, in the aspect of issuing the bill printed with the barcode, the registration information is obtained from the terminal (first POS terminal 20-1) that issued the bill or the terminal that issued the bill. If the received terminal (store controller 30 or the like) receives a registration information acquisition request transmitted from the POS terminal 20 (second POS terminal 20-2 or third POS terminal 20-3) that has read the bill, the registration information The registration information specified by the acquisition request is transmitted to the registration information acquisition request transmission source (registration information request source).

  The issued bill is handed to the customer from the store clerk. Thereafter, the customer moves to the POS terminal 20 (the first POS terminal 20-1 or the second POS terminal 20-2) and the POS terminal 20 (customer side scanner unit 206) reads the code on the bill. Based on this, the settlement process is executed in the POS terminal 20.

  The registration screen button BT26 is a button for returning the screen from the small plan surface to the registration screen. For example, the store clerk operates the registration screen button BT26 when changing (adding or canceling) the purchased product.

  For example, the store clerk may be provided with a drawer operated by the store clerk, a change bill machine, or the like, and the store clerk may receive cash from the customer and perform the settlement process. In this case, in FIG. 14, the current total button BT20 also serves as a button for instructing the input of the deposit amount, and the current total button BT20 is used when the store clerk receives cash etc. from the customer and performs the settlement process. It may be. When a cashier is provided on the store clerk side, a change amount is calculated by inputting the deposit amount and pressing the current button BT20, and a receipt or receipt is issued. If there is a change machine on the side of the clerk, when the cash deposited by the clerk is deposited into the change machine, the deposit amount is automatically calculated and the change is paid by pressing the current button BT20. It becomes the operation of putting out. In addition, as described above, the current total button BT20 is a button that is operated after inputting a deposit amount greater than or equal to the total amount, and FIG. 14 illustrates a situation where a deposit amount greater than or equal to the total amount is entered. Absent. Accordingly, in FIG. 14, as with the second register button BT22, the current total button BT20 may be displayed in a display mode indicating that the operation is not valid.

  Thus, when the registration process for one transaction is completed, the registration process for the next one transaction can be performed. Below, the following 1 transaction is demonstrated. FIG. 15 is a display example on the registration screen displayed on the clerk side display unit 210 of the first POS terminal 20-1 at the time of the next one transaction. Specifically, FIG. 15 shows the display content of the registration screen in a scene where two items of merchandise (carrots) are registered. For example, the registration screen is displayed after the store clerk reads a barcode (product code or the like) attached to the product and the registration process is started.

  When a plurality of transactions are performed, the registration screen has a structure in which sheets (product registration sheets) indicating the product registration contents corresponding to each transaction are stacked. For example, in FIG. 15, a state in which two product registration sheets are stacked is displayed. In the product registration tabs (areas) TAB-1 and TAB-2, symbols of arbitrary animals (here, “cat” and “cow”) are displayed. When a plurality of product registration tabs are displayed, the product registration tab corresponding to the transaction to be registered at present is displayed large, and the other tabs are displayed small. In the example shown in FIG. 15, since the transaction of the product registration tab (area) TAB-2 is a registration target, the product registration tab (area) TAB-2 is displayed large, and the product registration tab (area) that is not the registration target. TAB-1 is displayed small.

  In addition, the product registration tab (area) TAB-1 that is not the registration target shows the state of the corresponding transaction. In FIG. 15, “No2 cash register” is displayed in the product registration tab (area) TAB-1, and the transaction corresponding to the product registration tab (area) TAB-1 is processed (settlement processing) in the No2 cash register. It shows that.

  The merchandise registration tab (area) is added and displayed one by one every time the transaction is increased, and the merchandise registration tab (area) is deleted each time the transaction ends. It should be noted that registration order numbers such as “1”, “2”, and “3” may be displayed instead of an arbitrary animal symbol. The registration order number indicates, for example, the order in which registration of products is started.

  An image GA01 and an image GA02 are displayed in the lower left of the product registration sheet with the product registration tab (area) TAB-2 of “Cow”, and a subtotal button BT10 and a pause button BT11 are displayed in the lower right of the product registration sheet. It is displayed. These displays are common to all product registration sheets.

  When a plurality of product registration tabs (areas) are displayed, a recall button BT27 is displayed on the left side of the subtotal button BT10. The recall button BT27 is a button for recalling registration information transmitted to another POS terminal (second POS terminal 20-2 or third POS terminal 20-3). The store clerk operates (touches) the recall button BT27 when recalling the registration information transmitted to another POS terminal 20 (for example, the second POS terminal 20-2).

  When the subtotal key is operated, a small plan surface as shown in FIG. 14 is displayed. Further, when the recall button BT27 is operated, the transaction registration information corresponding to the product registration tab (area) TAB-1 transmitted to the second POS terminal 20-2 is recalled from the second POS terminal 20-2, as shown in FIG. As shown, the product registration sheet of the product registration tab (area) TAB-1 is displayed. At this time, the product registration tab (area) TAB-2 is displayed small. Further, “Registering” is displayed in the product registration tab (area) TAB-2, and the transaction corresponding to the product registration tab (area) TAB-2 indicates that registration processing is being performed.

  Note that a settlement screen is displayed on the second POS terminal 20-2 to which the registration information has been transmitted. The settlement screen is the same screen as the settlement screen (payment method selection screen) displayed when the settlement process in the full self mode shown in FIG. In the semi-self mode, the images shown in FIG. 12 are sequentially displayed on the customer-side display unit 205, and the customer performs checkout processing according to the procedure displayed on the customer-side display unit 205. While the checkout process is being performed, before the end (receipt) button BT40 shown in FIG. 12C is operated (pressed), the recall button BT27 shown in FIG. When operated (pressed), the registration information transmitted to the second POS terminal 20-2 is recalled to the first POS terminal 20-1.

  When the product registration sheet of the product registration tab (area) TAB-1 shown in FIG. 16 is displayed, the product registration in the transaction of the product registration tab (area) TAB-1 can be resumed and the product can be purchased. . Specifically, FIG. 17 shows display contents of a registration screen in a scene where three items of merchandise (mint gum) are registered.

  When the subtotal button BT10 shown in FIG. 17 is operated, a small plan plane shown in FIG. 18 is displayed. As with the small plan plane shown in FIG. 14, a current total button BT20 is displayed on the small plan plane shown in FIG. Further, after the registration information is recalled, the first POS terminal 20-1 shifts to the normal mode, so that the first register button BT21, the second register button BT22, and the bill button BT25 shown in FIG. 14 are displayed. Not. A deposit amount is input by operating the current total button BT20.

  Furthermore, when a new transaction is started when the product registration tab (area) TAB-1 and the product registration tab (area) TAB-2 are displayed, as shown in FIG. Area) TAB-3 is displayed. In the product registration tab (area) TAB-3, the symbol “Koala” is displayed. Here, the state where the transaction registration of the product registration tab (area) TAB-1 is performed is shown.

  Further, when the registration information is recalled, the registration information cannot be recalled when the POS terminal (first POS terminal 20-1) is in a state where the settlement process cannot be performed. The state in which the payment process cannot be performed at the POS terminal is, for example, near-end, near-full, receipt cut, failure of the change machine 209 or the printing unit 213. In determining near end, near full, receipt out, etc., for example, a threshold value or the like may be provided for each, and it may be determined that near end, near full, receipt out, etc. are exceeded. In this case, even if the recall button BT27 shown in FIG. 15 is operated, the registration information of the transaction in the product registration tab (area) TAB-1 is not displayed, and the reason why the recall cannot be performed is displayed.

  FIG. 20 shows error information when the settlement processing cannot be performed, such as a display when registration information cannot be recalled due to near-end. As specific error information, a message image GA20 including a message “Change is insufficient. Cannot be recalled” is displayed to notify the store clerk that the recall is not possible. In this case, for example, settlement may be performed by transmitting the registration information to the POS terminal (second POS terminal 20-2) that called back the registration information or to another POS terminal (for example, the third POS terminal 20-3). it can.

  Next, processing in the first POS terminal 20-1 from registration processing to settlement processing in the semi-self mode will be described. FIG. 21 is a flowchart illustrating an example from the registration process in the first POS terminal to the settlement process being performed.

Step S201: It is determined whether or not an operation for designating the settlement apparatus has been performed. Specifically, it is determined whether or not the first registration button BT21 or the second registration button BT22 shown in FIG. 14 has been operated (touched). If the first registration button BT21 or the second registration button BT22 is operated, the process proceeds to step S202. If there is no first registration button BT21 or second registration button BT22, the process of step S201 is repeated.
Step S202: Registration information is transmitted. Here, the registration information is transmitted to the cash register (POS terminal 20) corresponding to the operated cash register button. Specifically, when the first register button BT21 is operated, the registration information is transmitted to the No. 2 register (second POS terminal 20-2). When the second register button BT22 is operated, the registration information is transmitted to the No. 3 register (third POS terminal 20-3).

Step S203: A product registration tab (area) is displayed. Here, a product registration tab for the next registration and a product registration sheet corresponding to the product registration tab (area) are displayed. For the transaction for which the registration information is transmitted, only the product registration tab (area) is displayed, and the product registration sheet is hidden in the product registration sheet for the next transaction.
Step S204: It is determined whether or not the settlement process is completed. Specifically, it is determined whether payment completion information has been received from the POS terminal 20 (second POS terminal 20-2 or third POS terminal 20-3) that has transmitted the registration information. When the payment completion information has been received, it is determined that the payment process has been completed. When the payment completion information has not been received, it is determined that the payment process has not been completed. If it is determined that the payment process has been completed, the process proceeds to step S205. If it is determined that the payment process has not been completed, the process of step S204 is repeated.
Step S205: The corresponding product registration tab (area) is deleted. Specifically, the product registration tab (area) for the transaction transmitted to the other cash register (No. 2 cash register or No. 3 cash register) is deleted. Then, the flowchart of FIG. 21 ends.

  Next, processing in the first POS terminal 20-1 in the case where the registration information is called back when the settlement processing is being performed in the semi-self mode will be described. FIG. 22 is a flowchart illustrating an example of a process in the case where registration information is recalled during the settlement process in the first POS terminal.

Step S301: It is determined whether or not a call back button has been operated. Specifically, it is determined whether or not there has been an operation of pressing the call back button BT27 shown in FIG. If the call back button has not been operated, the process of step S301 is repeated. If the call back button BT27 has been operated, the process proceeds to step S302.
Step S302: It is determined whether or not there is a status error. Specifically, it is determined whether or not there has been a status error such as near end, near full, inability to give or receive money due to a failure of the change machine 209, or inability to issue a receipt due to receipt failure or failure of the printing unit 213. If there is a status error, the process proceeds to step S308. If there is no status error, the process proceeds to step S303.

Step S303: It is determined whether there are a plurality of recall candidates. Specifically, it is determined whether there are a plurality of unsettled transactions other than the transaction for which registration processing is currently being performed. The recall candidates are the transaction registration information of the product registration tab (region) other than the product registration tab (region) of the transaction for which the registration process is currently being performed, among the product registration tabs (region) shown in FIG. For this reason, when there are a plurality of product registration tabs (regions) other than the product registration tab (region) of a transaction for which registration processing is currently being performed, there are a plurality of recall candidates. In the example shown in FIG. 15, there is only one (one) product registration tab (region) other than the product registration tab (region) (product registration tab (region) TAB-2) of the transaction for which registration processing is currently being performed ( Product registration tab (area) TAB-1 only), there is only one recall candidate. In addition, as shown in FIG. 19, there are a plurality (two) of product registration tabs (regions) other than the product registration tab (region) (product registration tab (region) TAB-1) of the transaction for which registration processing is currently being performed. If there is a product registration tab (region) TAB-2, product registration tab (region) TAB-3, there is a product registration tab (region) other than the product registration tab (region) of the transaction that is currently being registered. The store clerk selects and operates one of (product registration tab (area) TAB-2, product registration tab (area) TAB-3).

Step S304: It is determined whether or not there is an operation on a product registration tab (area). If there are multiple registration information for transactions that are candidates for recall, multiple product registration tabs (areas) for the corresponding transactions are displayed. From the product registration tab (area), product registration for transactions that are subject to recall A clerk operates a tab (area). When the product registration tab (area) is operated, the process proceeds to step S305. If there is no operation on the product registration tab (area), the process of step S304 is repeated.
Step S305: Call-back information is transmitted to the POS terminal that is performing transaction settlement processing. When there is a single product registration tab (region) other than the product registration tab (region) of the transaction for which the registration process is currently being performed, the call is returned to the POS terminal 20 that performs the transaction settlement process for the product registration tab (region). Send information. For example, when the call back button BT27 is transmitted on the screen shown in FIG. 15, the call back information is transmitted to the No. 2 register (second POS terminal 20-2). When there are a plurality of product registration tabs (regions) other than the product registration tab (region) of the transaction for which the registration process is currently being performed, the POS for performing the transaction settlement process for the product registration tab (region) operated in step S304. Call-back information is transmitted to the terminal 20. For example, when the product registration tab (area) TAB-2 is operated on the screen shown in FIG. 19, the call-back information is transmitted to the No. 2 register (second POS terminal 20-2).

Step S306: It is determined whether or not the returned registration information has been received. The POS terminal 20 that has received the call-back information returns the registration information to the POS terminal 20 that has transmitted the call-back information. Here, it is determined whether or not the returned registration information is received. When the returned registration information is received, the process proceeds to step S307. If the returned registration information has not been received, the process of step S006 is repeated.
Step S307: Display the corresponding product registration tab (area) and product registration sheet. When the registration information returned from the POS terminal 20 that transmitted the call-back information is received, the product registration tab (area) corresponding to the registration information is changed to a product registration tab (area) TAB-1 shown in FIG. And a product registration sheet. The product registration tab (area) that is displayed at this time is displayed as small as the product registration tab (area) TAB-2 shown in FIG. 16, and the product registration sheet is the newly displayed product registration sheet. Position it on the back side. In addition, the operation mode of the first POS terminal 20-1 in the full self mode is shifted to the normal mode. Then, the flowchart of FIG. 22 ends.

Step S308: Display error details. The content of the status error when it is determined in step S302 that there was a status error is displayed. For example, when the POS terminal 20 is near-end, the message image GA20 shown in FIG. 20 is displayed on the customer side display unit 205 of the POS terminal 20. Then, the flowchart of FIG. 22 ends.

(Display on the customer side display unit 205 of the second POS terminal 20-2)
Next, the display on the customer side display unit 205 in the POS terminal 20 (second POS terminal 20-2) when registering information, sending registration information, and recalling the transmitted registration information is used with reference to FIGS. I will explain. 23 to 25 are display examples of the customer side display unit in the second POS terminal 20-2.

  FIG. 23 is a display example on the settlement screen displayed on the customer side display unit 205 of the second POS terminal 20-2. Specifically, FIG. 23 shows a state in which the check-out process has progressed and the call-back information is transmitted from the first POS terminal 20-1 in the scene shown in FIG. When the call-back information is transmitted from the first POS terminal 20-1, the second POS terminal 20-2 transmits the registration information to the first POS terminal 20-1, and the customer side display unit 205 of the second POS terminal 20-2. 23, a message image GA31 including a message “Called back to No1 cash register” is displayed as shown in FIG. 23, indicating that the registration information has been called back to the No1 cash register (first POS terminal 20-1). To inform.

  In the scene shown in FIG. 12C, the customer has already put in cash for payment. When recalling the registration information, the customer is made to select the handling of the cash inserted by the customer. Therefore, following the image shown in FIG. 23, a deposit withdrawal inquiry screen is displayed as shown in FIG. On the deposit refund inquiry screen, a message image GA32 including a message “Do you want to refund the deposit?” Is displayed, and coin refund button BT51, bill refund button BT52, full refund button BT53 and full price maintenance button BT54 are also displayed. Is displayed.

  The coin refund button BT51 displays a message “Return only coins”. When the coin refund button BT51 is operated, only the coins in the deposited money are refunded. Is transmitted to the first POS terminal 20-1 together with the registration information. In the bill reimbursement button BT52, a message of “refunding only banknotes” is displayed. When the bill reimbursement button BT52 is operated, only the banknotes in the deposited money are repaid, Is transmitted to the first POS terminal 20-1 together with the registration information.

  A message of “full refund” is displayed on the full refund button BT53, and when the full refund button BT53 is operated, the total amount paid is refunded. On the full amount maintenance button BT54, a message of “full amount as it is” is displayed, and when the full amount maintenance button BT54 is operated, the information on the total amount received is transmitted to the first POS terminal 20-1 together with the registration information. As shown in FIG. 12 (A) or FIG. 12 (B), when the second POS terminal 20-2 receives the call back information before the deposit is made, the image shown in FIG. 24 is not displayed. 25 is displayed.

  FIG. 25 shows an image displayed after the image shown in FIG. 23 or the image shown in FIG. 24 is displayed. As shown in FIG. 25, a message image GA41 including a message “Return to No1 cash register” is displayed on the customer side display unit 205 of the second POS terminal 20-2. In the message image GA41, an OK button BT61 displayed as “OK” is displayed. When the customer is performing the checkout process at the second POS terminal 20-2, the customer sees the message image GA41 and operates the OK button BT61 to return to the first POS terminal 20-1. In addition to the OK button BT, a clerk calling button may be provided to call the clerk. By calling the store clerk, the customer can confirm the change contents and subsequent processing without leaving the vicinity of the second POS terminal 20-2.

  Thus, after the registration information is called back to the first POS terminal 20-1, the second POS terminal 20-2 shifts to the full self mode. For this reason, a registration start screen (see FIG. 11A) in the full self mode is displayed on the customer side display unit 205 in the second POS terminal 20-2. In addition, without providing the OK button BT61 shown in FIG. 25, after displaying the message included in the message image GA41 for a predetermined time, for example, for a few seconds, the mode shifts to the full self mode and the registration start screen in the full self mode is displayed. You may make it do. If the registration information of the next transaction is transmitted to the second POS terminal 20-2, the settlement screen is displayed continuously in order to start the settlement processing of the next transaction without shifting to the full self mode. Is done.

  In the first POS terminal 20-1, when the current customer is being registered, it may be called back after the processing is completed, or the registration of the previous customer is performed by “temporarily holding” the registration of the current customer. However, in the case of temporarily suspending, the product registration tab (area) in which the product registration of the previous customer is completed is left until the payment is completed. At this time, the store clerk may perform a recall operation by touching the product registration tab (area) of the previous customer. At that time, you can also display a confirmation screen such as “Do you want to call back? (Yes / No) or only (OK). Also, if the customer registration is suspended, You can call back without displaying the confirmation screen, so you can easily call back and avoid mistakes.

  Next, processing in the second POS terminal 20-2 when registration return information is transmitted from the first POS terminal 20-1 while the settlement process is being performed in the semi-self mode will be described. FIG. 26 is a flowchart showing an example of the operation of the second POS terminal that has received the call-back information.

Step S401: It is determined whether registration information has been received. Here, it is determined whether registration information is received from the first POS terminal 20-1. If registration information has not been received, the process of step S401 is repeated. If registration information has been received, the process proceeds to step S402.
Step S402: A settlement screen is displayed. Here, the settlement screen (payment method selection screen) shown in FIG. 12A is displayed on the customer side display unit 205 of the second POS terminal 20-2.

Step S403: It is determined whether or not an end (receipt) button has been operated. After the screen shown in FIG. 12A is displayed on the customer-side display unit 205 of the second POS terminal 20-2, the checkout process proceeds, and the end (receipt) button BT40 shown in FIG. 12C is operated. It is determined whether or not. If the end (receipt) button BT40 is not operated, the process proceeds to step S404. If the end (receipt) button BT40 is operated, the process proceeds to step S412.
Step S404: It is determined whether call-back information has been received. Here, it is determined whether or not the call-back information transmitted from the first POS terminal 20-1 has been received. If the call-back information is received, the process proceeds to step S405. If the call-back information has not been received, the flowchart of FIG. 26 ends.

Step S405: Registration information is returned. Here, the second POS terminal 20-2 returns the registration information received in step S401 to the first POS terminal 20-1.
Step S406: A settlement screen (call back notification screen) is displayed. Here, an image including the message image GA31 shown in FIG. 23 is superimposed on the image displayed on the customer side display unit 205 of the second POS terminal 20-2 when the call-back information is transmitted. It is displayed on the customer side display unit 205.

Step S407: The settlement screen (deposit refund inquiry screen) is displayed. Here, a deposit withdrawal inquiry screen including the message image GA32 shown in FIG. 25 is displayed.
Step S408: A process corresponding to the operated button is executed. Specifically, any one of the coin refund button BT51, the bill refund button BT52, the full refund button BT53, and the full maintenance button BT54 included in the message image GA32 shown in FIG. To do. When the coin withdrawal button BT51 is operated, the coins in the deposited money are withdrawn, and information on the amount of the banknote is transmitted to the first POS terminal 20-1 together with the registration information. When the banknote withdrawal button BT52 is operated, the banknote in the deposited money is withdrawn, and information on the amount of coins is transmitted to the first POS terminal 20-1 together with the registration information. When the full amount refund button BT53 is operated, the total amount of the deposited money is refunded. When the full amount maintenance button BT54 is operated, information on the total amount received is transmitted to the first POS terminal 20-1 together with the registration information.

Step S409: A movement instruction display is performed. After any one of the coin refund button BT51, the banknote refund button BT52, the full refund button BT53 and the full maintenance button BT54 is operated, a message image GA41 shown in FIG. 25 is displayed. An OK button BT61 is displayed on the message image GA41.
Step S410: It is determined whether or not the OK button has been operated. When the OK button BT61 shown in FIG. 25 is operated, the process proceeds to step S411. If the OK button BT61 is not operated, the process of step S410 is repeated.

Step S411: A registration start screen (full self mode) is displayed. Here, the second POS terminal 20-2 is shifted to the full self mode, and the full self mode start screen is displayed on the customer side display unit 205 of the second POS terminal 20-2. Then, the flowchart of FIG. 26 ends.
Step S412: The settlement completion information is transmitted. In step S403, when the end (receipt) button BT40 is operated, the settlement process is completed. For this reason, the second POS terminal 20-2 receives the payment completion information to the first POS terminal 20-1. Then, the flowchart of FIG. 26 ends.

  As described above, according to the present embodiment, when the POS terminal 20 is operated in the semi-self mode, the POS terminal 20 that performs the registration process (for example, the first POS terminal 20-1) transmits the registration information. The registration information can be recalled from the POS terminal 20 (for example, the second POS terminal 20-2) that performs the checkout process. After recalling the registration information, the first POS terminal 20-1 shifts the operation mode from the semi-self mode to the normal mode. At this time, when the first POS terminal 20-1 cannot be settled, for example, when a status error has occurred, the recall cannot be performed, and when the first POS terminal 20-1 is in the settleable state, the registration information You can call back. For this reason, even if the registration information is recalled, the registration information is not recalled when it cannot be settled. Therefore, a reduction in operating efficiency of the first POS terminal 20-1 and the second POS terminal 20-2 is suppressed, and a plurality of POS terminals 20 can be operated efficiently.

  In addition, since the payment possible state of the first POS terminal 20-1 is determined based on the status such as whether or not there is a status error, the payment possible state of the first POS terminal 20-1 can be accurately determined. As a result, a plurality of POS terminals 20 can be operated efficiently.

  Further, according to the present embodiment, when the second POS terminal 20-2 is called back to the registration information transmitted from the first POS terminal 20-1, the operation mode is changed to the full self mode, which is another mode such as the semi self mode. The screen displayed after the transition and the registration information is recalled is set to the registration start screen in the full self mode. For this reason, the second POS terminal 20-2 operating in the semi-self mode can be used as the full self mode by recalling the registration information. Therefore, the operation mode can be switched according to the recall operation. Further, the operation mode can be switched without the store clerk performing the mode switching process manually or the like. Further, when a customer who wants to use the second POS terminal 20-2 in the full self mode is waiting, the registration process can be quickly started by the second POS terminal 20-2. Therefore, the second POS terminal 20-2 can be used efficiently after the registration information is called back.

  The operation mode in which the second POS terminal 20-2 shifts from the semi-self mode is the full self mode. For this reason, even when there is no store clerk near the second POS terminal 20-2, the second POS terminal 20-2 to which the registration information has moved can be quickly operated only by the customer. Therefore, since the second POS terminal 20-2 can be operated simultaneously while the first POS terminal 20-1 is operating, a plurality of POS terminals can be operated efficiently.

  Further, the second POS terminal 20-2 returns registration information to the first POS terminal 20-1 in accordance with the call-back information transmitted from the first POS terminal 20-1. For this reason, since information exchange can be performed between the first POS terminal 20-1 and the second POS terminal 20-2, the registration information can be corrected smoothly.

  The POS terminal 20 is provided with a change machine 209 for inputting cash. When the second POS terminal 20-2 receives the call-back information from the first POS terminal 20-1, the received cash is refunded. For this reason, it is possible to suppress miscalculation of money even when there is a purchase or cancellation of a product when performing settlement after the registration information is recalled.

  When the second POS terminal 20-2 receives the call-back information from the first POS terminal 20-1, the second POS terminal 20-2 repays banknotes out of the deposited cash and transmits information on the amount of coins to the first POS terminal 20-1. is doing. For this reason, when payment is made after the registered information is recalled, the worry about the loss of banknotes can be reduced if the product is added or canceled.

  Further, when the second POS terminal 20-2 receives the call-back information from the first POS terminal 20-1, the coin is repaid out of the deposited cash, and information on the amount of the banknote is transmitted to the first POS terminal 20-1. is doing. For this reason, since the trouble of depositing the same banknote once deposited can be saved, it is possible to simplify the deposit operation, particularly the deposit operation of the banknote.

  Further, when the second POS terminal 20-2 receives the call back information from the first POS terminal 20-1, the information on the deposited cash is transmitted to the first POS terminal 20-1 together with the registration information. For this reason, since the trouble of re-paying the money once deposited can be saved, the depositing operation can be simplified. In addition, since there is no refund of cash, it is possible to prevent forgetting to receive paid cash.

  In the above example, the POS system 1 includes the POS terminals 20 of the first POS terminal 20-1, the second POS terminal 20-2, and the third POS terminal 20-3, but includes two POS terminals. It may be a thing, and may be provided with four or more POS terminals. Further, although the POS system 1 includes the store controller 10 other than the POS terminal 20, the POS system 1 may not include the store controller. In this case, a specific one or any one of the plurality of POS terminals 20 is stored. It may have the same function as the controller.

  In the above example, when recalling registration information, after operating the recall button BT27, if there are multiple recall candidates, the registration information is selected by operating the product registration tab. However, you may make it select the registration information recalled in another aspect. For example, by operating the recall button BT27, an unsettled processing list screen including a list of registered information of transactions that have not been settled in other POS terminals 20 is displayed, and recalled from the displayed list of registered information. Registration information to be performed may be selected. This list may include registration information of transactions that are being registered, in addition to unsettled registration information. Further, the registration information that has been settled may be displayed in a different manner from the registration information that has not yet been settled, for example, by changing the background color and design, the color and size of characters, the font, and the like. When selecting the registration information to be recalled from the unsettled processing list screen, the transaction information is displayed side by side by selecting the list, so that the recall operation can be performed after confirming the transaction details. In addition to the first POS terminal 20-1, in this case, if there is a store clerk in the third POS terminal 20-3, the recall can be performed without being limited to the registered device.

  In the above example, the registration information moves when the first POS terminal 20-1 that has performed the registration process recalls the registration information from the second POS terminal 20-2. However, other modes may be used. For example, when the registration information is transmitted from the first POS terminal 20-1 that has performed the registration process to the second POS terminal 20-2 and the settlement process is to be performed by the second POS terminal 20-2, the second POS terminal 20-2 The movement information for moving the transmitted registration information to another POS terminal 20, for example, the third POS terminal 20-3, is transmitted to the second POS terminal 20-2, and the registration information is transmitted from the second POS terminal 20-2 to the third POS terminal 20. You may make it move to -3.

  In the above example, the first POS terminal 20-1 that transmitted the registration information to the second POS terminal 20-2 does not store the transmitted registration information, but prepares the transmitted registration information or a copy thereof in advance. Alternatively, the registration information or a copy thereof may be stored after transmitting the registration information. Further, a part of the registration information or a copy thereof may be stored. As for the registration information returned from the second POS terminal 20-2, only a part thereof, for example, a transaction number may be returned. In addition, the transmission / reception of information is not only performed directly between the transmission destination and the reception destination, but also between the transmission destination and the reception destination even when passing through another device, for example, the store controller 10. Send and receive.

  Further, in the above example, whether or not recall is possible is determined based on the status information, but whether or not recall is possible may be determined under other conditions. For example, when the first POS terminal 20-1 has a payment machine that performs payment by credit card or electronic money, it may be possible to call back, or the credit card displayed on the button shown in FIG. Alternatively, after the payment with electronic money is determined, the first POS terminal 20-1 may be able to recall the credit card or the electronic money used for these settlement methods. Or you may make it call back unconditionally.

  Further, in the above example, only one piece of transaction information can be stored in the POS terminal 20, but two or more pieces of transaction information may be stored so that the settlement process can be performed sequentially. . In this case, one POS terminal 20 may store a plurality of registration information, or a plurality of POS terminals may store registration information.

  In this case, when selecting the POS terminal 20 for recalling the registration information, the display of the color, shape, animal pattern, etc. of the product registration tab (area) TAB may be characterized and displayed for each POS terminal. For example, the color of the product registration of the first POS terminal 20-1 in which the registration information about the transaction first transmitted to the second POS terminal 20-2 is described may be changed for each POS terminal 20. For example, the product registration tab (region) of the transaction registration information transmitted to the second POS terminal 20-2 has a red background, and the product registration tab (region) of the transaction registration information transmitted to the third POS terminal 20-3. ) May be such that the background is all blue.

  Further, the color or the like may be changed for each registered round in each POS terminal 20. For example, in each of the second POS terminal 20-2 and the third POS terminal 20-3, the registration information of the first transmitted transaction is yellow, and the registration information of the second transmitted transaction is green. It may be entered on the product registration sheet with the mark. Further, similar or similar colors may be used instead of the same colors. For example, the registration information stored in the second POS terminal 20-2 is red, such as red, orange, vermilion, pink, and the registration information stored in the third POS terminal 20-3 is blue, green. Blue color such as light blue, bluish purple, etc. may be used.

  In addition, when the second POS terminal 20-2 can store a plurality of registration information, when the registration information of the transaction currently being processed is recalled with the plurality of registration information stored, the full self mode You may make it maintain semi-self mode, without shifting to. In other words, when the second POS terminal 20-2 detects a return of registration information, the second POS terminal 20-2 determines whether or not the registration information is stored, and shifts to the full self mode when determining that the registration information is not stored. The semi-self mode is maintained when memory is stored. In this case, since it is possible to smoothly perform the adjustment process of the registration information that has already been stored, the POS terminal can be operated efficiently. Further, when the registration information is recalled, the second POS terminal 20-2 may be on standby for correction of the recalled registration information. In this case, the customer waits for the registration information to be transmitted again without moving from the second POS terminal 20-2. A selection screen may be displayed on the customer-side display unit 205 so that the customer can select whether to enter standby or shift to the full self mode. Further, when the registration process or the settlement process is performed in the full self mode, after the settlement process is completed, the registration mode may be shifted to the semi-self mode when the registration information is not stored. In this case, even if the registration information is not stored, for example, after the payment process in the full self mode is completed, the next customer is waiting to start the registration process in the full self mode. The transition to may be prohibited. In order to prohibit the transition to the semi-self mode in this case, for example, after the processing in the full self mode is completed, the transition to the semi-self mode may be performed after a predetermined time, for example, 10 seconds elapses. When the next sensor is detected by the human sensor, the transition to the semi-self mode may be prohibited.

  Further, the POS terminal 20 may store the registration information of the transaction transmitted from the other POS terminal 20 to the other POS terminal 20 as unsettled registration information. For example, when the first POS terminal 20-1 transmits registration information to the second POS terminal 20-2, the third POS terminal 20-3 may take the registration information from the second POS terminal 20-2 and store it. . In this case, for example, the third POS terminal 20-3 may transmit the receipt information to the second POS terminal 20-2. In this way, the registration information moves between the POS terminals 20 in a manner such as recalling or picking up. In addition, unsettled registration information moved between a plurality of POS terminals 20 can be displayed as unsettled information on a product registration tab (area) in all POS terminals 20 or displayed as a list of unsettled products. Or you may make it.

  In the above example, the second POS terminal 20-2 that has returned the registration information in the semi-self mode shifts to the full self mode, and the customer side display unit 205 of the second POS terminal 20-2 displays the full self mode. The mode registration start screen is displayed, but the mode may be shifted to another mode. For example, the mode may be shifted to the normal mode or the double scan mode. In this case, the customer side display unit 205 of the second POS terminal 20-2 only needs to display a screen that is displayed first in the normal mode or the double scan mode. Further, the second POS terminal 20-2 that has returned the registration information may remain in the self mode. In this case, the customer side display unit 205 of the second POS terminal 20-2 that has returned the registration information only needs to display a screen that is displayed first in the semi-self mode.

  Further, in the above example, when the first POS terminal 20-1 is in an unaccountable state, the registration information cannot be recalled. When the settlement is possible, the registration information can be recalled, but the first POS terminal 20-1 The registered information may be recalled even when is in a state where payment is not possible. In this case, the first POS terminal 20-1 transmits the new registration information of the transaction including the recalled registration information to other POS terminals (second POS terminal 20-2, third POS terminal 20-3, etc.). It is preferable to perform the settlement process. In this case, the POS terminal 20 that transmits new registration information may be the POS terminal 20 to which the registration information has been recalled, or may be able to designate (select) the POS terminal 20 to be transmitted again. The selection in this case may include the own device. When new registration information is transmitted to the POS terminal 20 to which the registration information has been recalled, the customer is newly transmitted with the registration information being kept in the vicinity of the POS terminal 20 (for example, the second POS terminal 20-2). You may make it wait for it to come, or after moving to the POS terminal 20 (for example, the first POS terminal 20-1) that performs the registration process once, move to the POS terminal (for example, the second POS terminal 20-2) that performs settlement again. You may make it do. In the case of a mode in which the POS terminal 20 that transmits the registration information is newly specified, the customer can, for example, from the recalled POS terminal (for example, the second POS terminal 20-2) to the original POS terminal 20 (for example, the first POS terminal 20-). It is also possible to move to 1) to add or delete registration information, and then move to a designated POS terminal (for example, the third POS terminal 20-3) to perform settlement processing.

  In the above example, the POS terminal (second POS terminal 20-1) that shifts to the full self mode when the registration information is recalled during the checkout only mode, the normal mode, the full self mode, the semi self mode, And the double scan mode, the other modes may not be provided as long as they have the semi self mode and the full self mode. The POS terminal 20 has an operation mode such as a normal mode, a full self mode, and a semi self mode. However, the POS terminal 20 may be a POS terminal that performs at least one of a registration process and a payment process without providing an operation mode. In this case, there is no clear concept of the operation mode, but it should be provided with at least a part of the function equivalent to the function of the POS terminal 20 in the above example by the processing of the provided information or the store clerk. Also good.

  In the above example, even if a status error such as near end, near full, inability to give or receive money due to a failure of the change machine 209, or inability to issue a receipt due to a failure of the receipt or a failure of the printing unit 213, the recall is performed. However, if any of these occur, the recall may be disabled. Further, it may be possible to determine whether or not the call can be recalled according to the status of each status. For example, even if it is a near end, depending on the type of money, it may or may not be able to be recalled.

  In the above example, the registration information can be recalled even when the first POS terminal 20-1 is performing the settlement process. However, when the first POS terminal 20-1 is performing the settlement process, the registration information It may be made impossible to recall. In this case, it is possible to reduce the concern that the checkout process is complicated. As a result, a plurality of POS terminals 20 can be operated efficiently.

  Further, in the above example, when the registration information is recalled in the state where payment is made in the second POS terminal 20-2, the paid money is refunded in full, only the banknote, only the money. However, these may be selected in any manner and may not be selected. Also, when there are options that cannot be selected, for example, when there is an option that only the banknotes are refunded even though no banknotes have been deposited, the buttons for the options that cannot be selected are not displayed or grayed out. Thus, the customer may not be able to select.

  In the above example, the registration information is moved between the plurality of POS terminals 20 by transmission / reception or reply, but the registration information may be moved in another manner. For example, the registration information may be moved by writing the registration information on a code attached to the medium and moving the medium like a shopping ticket.

  In the above example, the POS terminal that performs the call-back transmits the call-back information. However, another POS terminal 20 or the store controller 10 may transmit the call-back information. For example, the registration information transmitted from the first POS terminal 20-1 to the second POS terminal 20-2 is called from the store controller 10 so as to return the registration information from the second POS terminal 20-2 to the first POS terminal 20-1. The return information may be transmitted to the second POS terminal 20-2. Also, when the registration information transmitted from the first POS terminal 20-1 to the second POS terminal 20-2 is moved to the third POS terminal 20-3, the collection information is received from the POS terminal 20 other than the third POS terminal 20-3. The receipt information may be sent from another POS terminal 20 or the store controller 10 instead of sending.

  In the above example, the POS system 1 is configured to include the POS terminal 20 that can perform both the registration process and the settlement process, but may be configured to include other POS terminals. . For example, a POS terminal that can perform the registration process and cannot perform the settlement process may be included, or a POS terminal that cannot perform the registration process and can perform the settlement process may be included. These POS terminals may be provided in place of the POS terminal 20 that can perform both the registration process and the settlement process.

  In the above example, when the POS terminal 20 transmits the registration information to the other POS terminals 20, the other POS terminals 20 are not particularly limited. However, there is a POS terminal 20 that cannot transmit. May be. The POS terminal 20 that cannot transmit may be disabled when, for example, a status error occurs, for example, near end, near full, or receipt is out of order. Further, transmission may be disabled when the number of registration information that can be registered in the POS terminal 20 is an upper limit. Further, whether or not transmission is possible may be different depending on the operation mode of the POS terminal 20. For example, transmission to the POS terminal 20 in the normal mode may be disabled. In determining the mode, validity / invalidity may be determined by flag management or the like according to system conditions or the like). Further, in the case of the POS terminal 20 in the full self mode or the checkout mode, transmission may be disabled when an operation by another customer is performed. Further, the condition of the POS terminal 20 for disabling transmission of registration information and the condition of the POS terminal 20 for disabling call back may be common or different.

  In the above example, a receipt or receipt (receipt, etc.) is issued when payment is completed. For example, a receipt (receipt) unnecessary button is provided, and issuance of (receipt, etc.) is omitted. You may be able to do it. The receipt (receipt) unnecessary button may be provided on the customer side display unit 205 or the store clerk side display unit 210, for example. Further, the key operation unit 211 may be provided. By making it possible to omit the issuance of receipts, etc., it is possible to contribute to the reduction of receipt paper.

  Further, when issuance of printing (receipt or the like) printed on a paper medium such as receipt paper is omitted, an electronic receipt may be issued instead of (receipt or the like). In this case, for example, by performing user registration in advance and entering user identification information (membership number) etc., an electronic receipt may be automatically issued instead of (receipt etc.), a receipt etc. Or an electronic receipt may be made to be selected by the customer. Or you may make it issue both a receipt etc. and an electronic receipt. In this case, the selection screen may be displayed to allow the customer to select, or the selection screen may be omitted by registering a selection pattern for each user in advance. As an issue mode of a receipt or the like, for example, non-issue, paper medium only, electronic receipt only, or both paper medium and electronic receipt may be selected. In this case, the selection screen may be provided on at least one of the customer side display unit 205, the store clerk side display unit 210, and the key operation unit 211. At this time, a receipt or the like may be issued simultaneously with the change. When the change is paid out and the receipt is issued, the receipt may be issued after the change is paid out, or the change may be paid out after the receipt is issued. When issuing a receipt, the customer may pay out change after receiving the receipt to prevent forgetting to take the receipt.

  Further, when the second POS terminal 20-2 and the third POS terminal 20-3 are on standby while the store clerk operates the first POS terminal 20-1, the second POS terminal 20-2 and the third POS terminal 20-3. The operation mode is not particularly limited. For example, a full self mode may be set. By waiting in the full self mode, a plurality of POS terminals 20 can be used efficiently. Further, when the cashier waiting at the first POS terminal 20-1 increases, the store clerk of the first POS terminal 20-1 transmits the registration information to one of the second POS terminal 20-2 and the third POS terminal 20-3 to checkout mode. Can be operated as Alternatively, registration information in the transaction for which the registration process has been completed is transmitted to the second POS terminal 20-2 or the third POS terminal 20-3 so that the second POS terminal 20-2 or the third POS terminal 20-3 can take over the settlement process. May be. For example, in the case where the second POS terminal 20-2 takes over the checkout process, when the second POS terminal 20-2 is operating in the full self mode, the registration information is transmitted to the second POS terminal 20-2, After the settlement in the self mode is completed, the settlement screen (payment method selection screen) shown in FIG. 12A may be displayed instead of the registration start screen shown in FIG.

  In the above example, by operating the recall button BT27 with the product registration tab (area) open, the transaction registration information corresponding to the product registration tab (area) is recalled. Registration information may be recalled. For example, the registration information corresponding to the product registration tab (area) may be recalled by opening the product registration tab (area) after operating the recall button BT27, or after operating the recall button BT27. The registration information transmitted to the second POS terminal 20-2 or the third POS terminal 20-3 corresponding to the first registration button BT21 or the second registration button BT22 by operating the first registration button BT21 or the second registration button BT22. May be recalled.
