(Overview of each operation mode)
Next, the operation mode of the POS terminal 20 will be described. The POS terminal 20 has a plurality of operation modes. Specifically, the POS terminal 20 has four types of operation modes (normal mode, full self mode, double scan mode, and semi self mode). The operation mode described below is an operation mode during normal business (operation mode relating to product registration processing and accounting processing), and is an aggregation mode for totalizing and inquiring sales and occupancy, etc. It does not include a maintenance mode for performing setting work or maintenance work, a training mode for newcomer training, and the like.

5 to 8 are diagrams for explaining the outline of the operation mode of the POS terminal. FIG. 5 is a diagram illustrating an outline of the normal mode. FIG. 5A is a schematic diagram showing the flow of processing (product registration processing, accounting processing) and the operation of a person (clerk, customer) in the normal mode, and FIG. 5B is a schematic diagram of the POS terminal 20 in the normal mode. 6 is a flowchart illustrating a basic flow of an operation.
FIG. 6 is a diagram schematically illustrating the full self mode. FIG. 6A is a schematic diagram showing the flow of processing (product registration processing, accounting processing) and the operation of a person (customer) in the full self mode, and FIG. 6B is a schematic diagram of the POS terminal 20 in the full self mode. 6 is a flowchart illustrating a basic flow of an operation. FIG. 7 is a diagram schematically illustrating the double scan mode.
FIG. 7A is a schematic diagram showing the flow of processing (product registration processing, accounting processing) and the operation of a person (customer) in the double scan mode, and FIG. 7B is a schematic diagram of the POS terminal 20 in the double scan mode. 6 is a flowchart illustrating a basic flow of an operation. FIG. 8 is a diagram schematically illustrating the semi-self mode.
FIG. 8A is a schematic diagram showing the flow of processing (product registration processing, accounting processing) and the operation of a person (customer) in the semi-self mode. FIGS. 8B and 8C are diagrams showing the flow in the semi-self mode. 4 is a flowchart showing a basic flow of an operation of the POS terminal 20.

  In the following description, as a different aspect from the classification of the above-described four operation modes, the POS terminal 20 sets the mode in which the product registration process is executed to the registration mode, and the mode in which the payment process is executed to the accounting mode (or the payment mode). Mode).

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

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

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

  That is, in the normal mode, as shown in FIG. 5B, the salesclerk first scans a product by the salesclerk-side scanner unit 212, for example (step S10: YES), and registers the product (step S11). After pressing a subtotal key (for example, a subtotal key displayed on the clerk side display unit 210 or a subtotal key arranged on the key operation unit 211) (step S30: YES), the customer side, for example, the change machine 209 (Step S50), and the process is completed.

  The customer may wait until the clerk completes the registration process (until the total amount is determined), or may put money into the change machine 209 before the registration process is completed. That is, the POS terminal 20 can accept payment during the registration process (the upper part of FIG. 5A).

  In addition, the clerk may wait until the customer completes the payment (until the customer takes a change or receipt), or may register the purchased product of the next customer. In other words, the POS terminal 20 can register the purchased product of the next customer during the settlement process (the lower part of FIG. 5A). Further, the clerk may be absent during the checkout by the customer (the lower part of FIG. 5A). That is, during the checkout of the customer, the reception of the customer may be ended.

  In addition, when there is change, the POS terminal 20 controls the dispensing of change and bills by the change machine 209 in order to prevent forgetting to take change, and a sensor or the like detects that the customer has removed the change or bill. , And controls the printing unit 213 to issue a receipt. The same applies to other operation modes. As described above, in the normal mode (the same applies to the double scan mode), there are cases where a clerk is present before and after a customer receiving change, but when a clerk is present, the above-described control is not necessarily performed. (I.e., the dispensing of the change and the bill and the issuing of the receipt may be performed at the same time, or the receipt may be issued first). In addition, the timing of paying out change and bills and issuing a receipt may be controlled in accordance with the current operation mode and the presence / absence of a clerk (for example, the presence / absence of a clerk is recognized by a sensor).

(Full self mode)
The full self mode is an operation mode in which a customer performs a registration process and a customer performs a settlement process as shown in FIG. That is, as shown in FIG. 6 (B), in the case of the full self mode, the customer is in both the registration mode and the accounting mode. That is, the POS terminal 20 operates in the registration and accounting mode when viewed from the entire registration processing to the settlement processing.

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

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

  That is, in the full self mode, as shown in FIG. 6B, on the customer side, for example, a product is scanned by the customer side scanner unit 206 (step S20: YES), and the product is registered (step S21). After 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's side performs settlement by, for example, the change machine 209 (step S50). Is completed.

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

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

  In the double scan mode, the clerk registers the purchased product on the clerk side (the clerk side scanner section 212, the clerk side display section 210, the key operation section 211), and the customer registers the purchased product on the customer side (customer side scanner section). 206, registered in the customer side display unit 205). In other words, the POS terminal 20 operates the clerk (scanning by the clerk-side scanner unit 212, touching the clerk-side display unit 210, pressing the key operation unit 211, etc.), and customer operation (the customer-side scanner unit 206). , A touch on the customer-side display unit 205) to execute a registration process of the purchased merchandise (the upper part of FIG. 7A).

  When the registration process is completed, the customer checks the total price of the purchased merchandise on the customer-side display unit 205, inserts money into the change machine 209, or operates the card settlement unit 208 to make a payment (FIG. 7A ) Lower row). That is, the POS terminal 20 executes the settlement process by a customer operation or the like (insertion of money into the change machine 209, operation of the card settlement unit 208) (the lower part of FIG. 7A).

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

  The clerk may wait until the customer completes the payment (until the customer takes a change or receipt), or may register the next customer's purchase. In other words, the POS terminal 20 can register the purchased product of the next customer during the settlement process (the lower part of FIG. 7A). Also, the clerk may be absent during the checkout by the customer (lower part in FIG. 7A). That is, during the checkout of the customer, the reception of the customer may be ended.

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

  In the case of the semi-self mode, the clerk uses the POS terminal 20 in the registration-only mode to register the purchased product of the customer on the clerk side (the clerk side scanner section 212, the clerk side display section 210, and the key operation section 211). That is, the POS terminal 20 executes the registration process of the purchased product by the operation of the clerk (operation of the clerk-side scanner unit 212, the clerk-side display unit 210, the key operation unit 211, and the like) (the 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, checks the total price of the purchased product on the clerk-side display unit 210, inserts money into the change machine 209, or setstles the card. The user operates the unit 208 to perform the payment (lower part in FIG. 8A). That is, the POS terminal 20 executes the settlement process by a customer operation or the like (insertion of money into the change machine 209, operation of the card settlement unit 208) (the lower part of FIG. 8A).

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

  The destination POS terminal 20 (the POS terminal 20 for executing the settlement process among the POS terminals 20 in the accounting-only mode) may be designated by the POS terminal 20 in the registration-only mode. Alternatively, the POS terminal 20 in the registration-only mode issues a medium (a medium on which a barcode or the like for acquiring information necessary for the settlement process is printed) and issues the medium to read the medium. The destination POS terminal 20 may be used.

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

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

  Note that after transmitting the registration information, the clerk can register the purchased product of the next customer (lower part in FIG. 8A). The clerk may be absent after transmitting the registration information (lower part of FIG. 8A). Further, the registration-only mode may not be provided. In other words, in the normal mode, it is sufficient that the registration information can always be specified to another POS terminal 20 as in the registration-only mode. In the normal mode, there is no need to disable the transmission function. In this case, in the normal mode, as described above, the clerk executes the registration processing, and executes the payment processing on the customer side of the terminal using the registration information generated in the registration processing (see FIG. 5). ), The clerk performs a registration process, and transmits the registration information generated in the registration process to another terminal (another terminal capable of executing a settlement process, for example, another POS terminal 20) (via the LAN 11). Directly to the other terminal, or transmitted to the other terminal via the store controller 10 or the monitoring terminal (not shown). The same applies hereinafter), and registration information or the like generated in the registration process is code ( It is also possible to execute a process of converting the barcode into a barcode, a two-dimensional code, and the like, printing it on a medium, and issuing it as a bill. That is, the POS terminal 20 in the normal mode has a function of registering a product in its own terminal and making a payment in another terminal in addition to a function of registering a product in its own terminal and making a payment in the own terminal. Further, the POS terminal 20 in the normal mode has a function of registering a product on its own terminal and making payment on another terminal, like the POS terminal 20 in the semi-self mode (registration only mode). The POS terminal 20 in the normal mode (similarly to the POS terminal 20 in the semi-self mode (accounting-only mode)) may have a function to settle the merchandise registered at another terminal, as in the POS terminal 20 in the semi-self mode. In other words, the POS terminal 20 in the full self mode or the POS terminal 20 in the normal mode receives registration information from another terminal (the POS terminal 20 in the semi-self mode (registration only mode), the POS terminal 20 in the normal mode, etc.) (or The accounting ticket may be read) and the settlement process may be executed.

(Notification of operation mode)
The POS terminal 20 reports the current operation mode. For example, the clerk-side display unit 210 may display the current operation mode. Specifically, a screen having an operation mode display section may be displayed on the clerk-side display section 210, and the current operation mode may be displayed in the operation mode display section on the screen. Also, a screen on which images (for example, button-like images) corresponding to each operation mode are arranged is displayed on the clerk-side display unit 210, and an image corresponding to the current operation mode is displayed on the screen. The image may be displayed in a display mode different from the non-corresponding image (for example, a display mode that is more conspicuous than the display mode of other images). The operation mode may be displayed on the customer display unit 205 in the same manner.

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

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

  9 and 10 are diagrams illustrating an example of the transition of the operation mode. 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 of FIG. 9A starts when the POS terminal 20 (normal mode) is in a non-use state (that is, starts when neither the clerk nor the customer is used).

Step S100: Start timing of non-use time.
Step S101: It is determined whether or not use has been started by a clerk or customer. If the use has not been started, the process proceeds to step S102. If the use has been 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, 10 minutes set in advance). 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: End time of non-use time. Then, the flowchart of FIG. 9A ends.

  When the mode shifts to the full self mode, the store clerk may be notified that the mode has shifted to the full self mode (for example, information indicating that there is an undelivered product is transmitted to a 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 register by self 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 of FIG. 9A. It may be.

(Transition from full self mode to double scan mode)
The flowchart in FIG. 9B is always started (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 is 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 in 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 in FIG. 10A always starts (periodically at very short time intervals) in the POS terminal 20 (normal mode).

Step S120: It is determined whether or not an operation for declaring transition to the semi-self mode (registration only mode) has been performed. For example, a button for declaring a shift 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 an operation has been performed, the process proceeds to step S121. If there is no operation, the flowchart in FIG. 10A ends.

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, at least one POS terminal 20 in the registration-only mode and one or more POS terminals 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 or not another POS terminal 20 to be shifted to the semi-self mode (accounting-only mode) has been designated. If there is a designation, 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 or not the processing is being performed. If not, the process proceeds to step S125. If the process is being performed, the process of step S124 is repeated.
Step S125: The operation mode is shifted from the normal mode to the semi-self mode (registration only mode). Then, the flowchart in FIG. 10A ends.

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

(Transition from normal mode to semi-self mode (accounting only mode))
The flowchart of FIG. 10B is always started (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 the transfer instruction has been received, the process proceeds to step S131. If the transfer instruction has not been received, the flowchart in FIG. 10B ends.

Step S131: It is determined whether or not the processing is being performed. If not, the process proceeds to step S132. If the process is being performed, the process of step S131 is repeated.
Step S132: The operation mode is shifted 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). The transition from the full self mode to the semi-self mode (accounting-only mode) is also shown in FIG. It may be the same as the flow of 10 (B). Separately from the transfer instruction, in the full self mode, when the device detects registration information to be processed by the own device, the device immediately enters the accounting-only mode if the device is on standby, and the transaction is performed if another customer is operating the transaction. After completion, the mode may be switched to the accounting-only mode. That is, the transfer instruction can be determined based on detection (reception) of the registration information. Further, the transfer instruction may be performed by operating another information terminal such as a mobile terminal such as a smartphone possessed by a clerk or a mobile terminal used for inventory of store display products.

(Display in full self mode)
Subsequently, the display of the POS terminal 20 in the full self mode will be described with reference to FIGS. 11 and 12 show 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 the 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 illustrated example, a button for switching between English, Chinese, and Korean is displayed because Japanese is selected. For example, when English is selected, a registration start screen in English is displayed. Then, a button for switching to Japanese, Chinese, and Korean is 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 illustrated example, on the right side of the registration screen, a registered product name, a unit price, the number of registered products (purchase points), and a total price are displayed as registration contents. Here, the registered contents of a scene where two items of commodities (pear and apple) are registered are displayed. Immediately after the registration start button BT30 is operated on the registration start screen shown in FIG. 11A to shift to the registration screen, a registration screen in which no product has been registered yet (a registration screen in an initial state). Is displayed, but for convenience of explanation, FIG. 11B shows an example of a registration screen after a product has already been registered.

  The checkout 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 settlement process. The clerk call button BT33 is a button for calling a clerk. The customer operates the clerk call button BT33 when calling the clerk (for example, when the clerk needs support). When the customer operates the clerk call button BT33, for example, a notification is sent to a portable terminal possessed by the clerk, a sound is output from the portable terminal, or the portable terminal vibrates. Further, when the customer operates the clerk call button BT33, a predetermined lamp (indicating light 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 “vegetables” button BT38 is a button for registering a product without a barcode (here, vegetables) from a preset key. For example, when the customer operates the “vegetables” button BT38, a preset screen in which each of the vegetables can be registered by operating the preset key is displayed. In the illustrated example, only the “vegetables” button BT38 is illustrated, but the “vegetables” button BT38 is used as a button for registering any product such as meat, fresh fish, prepared food, bread, etc. from the preset key. Can be displayed instead of or in addition to. In addition. The setting of the preset key is performed in advance in the POS terminal 20 by a clerk or the like.

  When the customer operates the checkout button BT32, the POS terminal 20 shifts to the checkout mode, and the display on the customer side display unit 205 changes from the registration screen to the settlement 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 shows a payment screen (payment method selection screen) displayed when the payment processing is started. For example, when the checkout button BT32 is operated on the registration screen (see FIG. 13B), the POS terminal 20 displays a payment method selection screen as shown in FIG. 12A. The payment method selection screen shown in the figure displays the total amount of payment (240 yen in this case), payment method options, and the like. As options for the payment method, cash, credit, electronic money, and the like are displayed as selectable operation buttons.

  FIG. 12B is a settlement screen (payment screen) displayed when starting payment by cash. 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. 12B. On the deposit screen shown in the figure, an image showing a guide for a place to put money is displayed on the left side of the screen, and a payment amount (here, 240 yen), an inserted amount (deposited amount) and the like 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, when cash (deposit) equal to or more than the payment amount (purchase amount) is inserted, the POS terminal 20 displays a payment determination screen as shown in FIG. In the illustrated payment determination screen, the payment amount (here, 240 yen), the inserted amount (deposit amount, here, 250 yen), change (here, 10 yen), and the like are displayed on the right side of the screen. On the left side of the screen, guidance for determining the deposit amount (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 a settlement process based on the payment amount (here, 240 yen) and the deposit amount (here, 250 yen).

  FIG. 12D shows a settlement screen (change screen) displayed when a change 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. 12D. In the change screen shown in the drawing, an image for prompting receipt of change is displayed on the left side of the screen, and the payment amount (240 yen in this case) and the inserted amount (deposited amount in this case, 250 yen) are continuously displayed on the right side of the screen. Yen), fishing (here, 10 yen) and the like are displayed.

  FIG. 12E shows a settlement screen (receipt screen) displayed when change has been removed. For example, when the change is removed from the exit of the change machine 209, the POS terminal 20 displays a receipt screen as shown in FIG. The POS terminal 20 may be provided with a sensor such as a photo sensor in the vicinity of the take-out opening, and when the sensor recognizes an object (assuming a customer's hand), it may be determined that the change has been removed. Furthermore, after detecting that change has been removed, a function of printing a receipt or a receipt may be provided to prevent forgetting to take change.

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

  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 issuing 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 input 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 changed from the deposit screen (FIG. 12C). )).

  As described above, in the full self mode, when the customer registers and pays for a product to be purchased, the POS terminal 20 operates the registration start screen and the registration screen shown in FIGS. , A payment screen or the like is displayed on the customer-side display unit 205. The POS terminal 20 also causes the clerk-side display unit 210 to display the same display content as that displayed on the customer-side display unit 205. For example, the POS terminal 20 causes the clerk-side display unit 210 to display the same screen as the screen of the customer-side display unit 205 (so-called mirror display, mirroring display). Displaying similar display contents is not limited to displaying exactly the same screen, but also includes a part of display contents and layout being different. For example, in the case of the registration screen, the contents essential for the registration operation (for example, the name of the registered product, the unit price, the number of the registered products (the number of purchases) and the total amount in FIG. "Button BT38, checkout button BT32, etc.) may be displayed on any of the display units, and even if at least part of other display contents is different, the same display contents may be displayed. .

(Recall registration 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 -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. The recall of the registration information means that after transmitting the registration information to the POS terminal (the second POS terminal 20-2), the payment processing to be executed by the POS terminal (the second POS terminal 20-2) is suspended based on the registration information, or This is to cancel the registration information and return the transmitted registration information to the POS terminal (first POS terminal 20-1). The recall generally corresponds to a case where registration information or the like is corrected, for example, when canceling a product registered by a POS terminal (first POS terminal 20-1) or when additionally registering a product for purchase. Done. Specifically, the correction of the registration information and the like includes the addition of a product, the correction of the quantity, the deletion, a discount operation by a privilege, the input of member identification information, and the like.

  The recall of registration information is, for example, after performing the registration process, when the customer notices that he has left his wallet in a car etc., he goes back to get his wallet or looks for a family with insufficient money And so on. After the recall operation, the second POS terminal 20-2 can execute another operation. Alternatively, the operation may be put on hold, and the corrected registration information may be received again to perform the settlement process. In addition, in the first POS terminal 20-1, the recalled registration information can be put on hold, and the product registration of another customer can be performed.

(Display of the clerk-side display unit 210 on the first POS terminal 20-1)
Hereinafter, the display of the clerk-side display unit 210 in the POS terminal 20 (first POS terminal 20-1) when transmitting the registration information and recalling the transmitted registration information from product registration will be described with reference to FIGS. 13 and 14. I do. FIG. 13 and FIG. 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, the first POS terminal 20-1 is a registration-only mode in the semi-self mode, and the second POS terminal 20-2 is a transaction-only mode in the semi-self mode. The third POS terminal 20-3 is assumed to be in a full self mode. It is also assumed that the registration process is performed at the first POS terminal 20-1, and the settlement process is performed at the second POS terminal 20-2. After the first POS terminal 20-1 recalls the registration information, 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 reply of the registration information (transmitted to the first POS terminal 20-1), and shifts to the full self mode when detecting the reply of the registration information.

  FIG. 13 is a display example of a registration screen displayed on the clerk-side display unit 210 of the first POS terminal 20-1. Specifically, FIG. 13 shows the display contents of a registration screen in a situation where two items of merchandise (aspara) are registered. The registration screen is displayed, for example, after a clerk reads a barcode (product code or the like) attached to a 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. The product registration sheet is provided with a tab (region) (product registration tab (region): an example of a heading region). In FIG. 13, one product registration tab (area) TAB-1 is displayed. On the product registration tab (area) TAB-1, a symbol of an arbitrary animal (here, "cat") is displayed.

  In FIG. 13, the lower left image GA01 of the product registration sheet with the product registration tab (area) TAB-1 of "cat" indicates the state of the No. 2 cash register (the second POS terminal 20-2 in FIG. 1). . The image GA02 at the lower left of the product registration sheet shows the state of the No. 3 cash 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 clerk operates (touches) the subtotal button BT10 after completing the product registration. The pause button BT11 is a button for suspending the terminal (the first POS terminal 20-1). The clerk operates the pause button BT11 when leaving the terminal (for example, when searching for a product or not using the terminal for a while).

  FIG. 14 is a display example on the small planning plane displayed on the clerk-side display unit 210 of the first POS terminal 20-1. More specifically, FIG. 14 shows the display contents of the sub-planning plane in the scene following the scene of FIG. 13 (the scene after the operation of the subtotal button BT10).

  In FIG. 14, the current total button BT20 is a button having the same function as the end (receipt) button BT40 which is pressed after the customer deposits the change in the bill change machine. If the customer is confused by the operation of pressing the end (receipt) button BT40, the clerk presses the total button BT20 on behalf of the customer, and the same as when the end (receipt) button BT40 is operated. Is performed, for example, a change is paid out from a change change machine, or a receipt is issued.

  The first cash register button BT21 is a button for designating a No. 2 cash register (the second POS terminal 20-2 in FIG. 1). The clerk operates the first cashier button BT21 when designating the second POS terminal 20-2 as the terminal for executing the payment processing. In addition, the display of "(payment)" shown on the first cashier button BT21 indicates that the operation mode of the terminal (the second POS terminal 20-2) corresponding to the first cashier button BT21 is the payment mode of the semi-self mode. It is a representation.

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

  The second cashier button BT22 is a button for designating a No. 3 cashier (the third POS terminal 20-3 in FIG. 1). The clerk operates the second cashier button BT22 when designating the third POS terminal 20-3 as the terminal for executing the payment processing. “(Full)” shown on the second cashier button BT22 indicates that the operation mode of the terminal (third POS terminal 20-3) corresponding to the second cashier button BT22 is the full self mode. is there. The broken line of the second cashier button BT22 indicates that the operation of the button (second cashier button BT22) is displayed in a display mode (for example, gray-down) indicating that the operation is not valid.

  In the example shown in FIG. 14, the operation of the second registration button BT22 is not valid, but if the operation of the second registration button BT22 is valid and the operation of the second registration button BT22 is received, The first POS terminal 20-1 transmits the registration information to the No. 3 cash register (the third POS terminal 20-3). By operating the first cash register button BT21 and transmitting the registration information to the second POS terminal 20-2, the registration processing of one transaction in the first POS terminal 20-1 is completed. Further, the transmission button is always displayed during product registration and displays the status of other devices, so that the device to be settled can be selected flexibly according to the situation. In FIG. 14, the display positions of the first register button BT21 and the second register button BT22 are changed from the display positions of the images GA01 and GA02, but the display positions of the images GA01 and GA02 are changed without changing the display positions. The first register button BT21 and the second register button BT22 may be displayed at the respective positions.

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

  Information necessary for executing the checkout process is coded and printed on the check voucher. For example, the registration information itself used in the checkout process may be converted into a QR code (registered trademark) and printed, or information for specifying the registration information used in the checkout process (for example, a transaction). Identification information, etc.) may be printed as a bar code.

  Note that, in the mode of issuing a bill printed with the QR code, the POS terminal 20 (the second POS terminal 20-2 or the third POS terminal 20-3) that has read the bill (QR code) is, for example, The settlement process is performed using the registration information obtained from the QR code. Further, in the mode of issuing the bills printed with the barcode, the POS terminal 20 (the second POS terminal 20-2 or the third POS terminal 20-3) that reads the bills (barcode) is, for example, The registration information acquisition request including the information (transaction identification information, etc.) for specifying the registration information obtained from the barcode is sent to the terminal (the first POS terminal 20-1) that has issued the bill, or By transmitting the registration information from the terminal that has issued the voucher to the terminal that has acquired the registration information (for example, the store controller 30), the registration information is received from the terminal that has transmitted the registration information acquisition request, and the settlement process is executed. In other words, in the mode in which the bill is printed with the barcode, the registration information is acquired from the terminal that issued the bill (the first POS terminal 20-1) or the terminal that issued the bill. When the terminal (the store controller 30 or the like) receives the registration information acquisition request transmitted from the POS terminal 20 (the second POS terminal 20-2 or the third POS terminal 20-3) that has read the bill, the registered information The registration information specified by the acquisition request is transmitted to the source of the registration information acquisition request (the source of the registration information).

  The issued accounting voucher is handed to the customer by the 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 (the 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 planning plane to the registration screen. The clerk operates the registration screen button BT26, for example, when changing (adding or canceling) the purchased product.

  Note that, for example, a drawer or a change bill machine operated by the clerk may be provided on the clerk side, and the clerk may receive cash or the like 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 a clerk receives cash or the like from a customer and performs a settlement process. It may be. When a cashier is provided with a drawer, a change amount is calculated by inputting a deposit amount and pressing a total button BT20, and a receipt, a receipt issuance, and the like are performed. If a change clerk is provided on the clerk's side, when the clerk deposits the cash received from the customer into the change change machine, the deposit amount is automatically calculated, and the change is paid by pressing the current total button BT20. It is an operation of putting out. Further, as described above, the total button BT20 is a button operated after inputting the deposit amount equal to or more than the total amount, and FIG. 14 shows a case where the deposit amount equal to or higher than the total amount is input. Absent. Accordingly, in FIG. 14, as with the second cashier 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 processing of one transaction is completed, the registration processing of the next transaction can be performed. The following one transaction will be described below. FIG. 15 is a display example of a 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 contents of a registration screen in a scene where two items of goods (carrots) are registered. The registration screen is displayed, for example, after a clerk reads a barcode (product code or the like) attached to a product and the registration process is started.

  The registration screen has a structure in which, when a plurality of transactions are performed, sheets (product registration sheets) indicating the product registration contents corresponding to each transaction are overlaid. For example, FIG. 15 shows a state where two product registration sheets are stacked. On the product registration tabs (areas) TAB-1 and TAB-2, symbols of arbitrary animals (here, "cat" and "cow") are displayed. When a plurality of merchandise registration tabs are displayed, the merchandise registration tab corresponding to the transaction to be currently registered 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 to be registered, the product registration tab (area) TAB-2 is displayed in a large size, and the product registration tab (area) not to be registered is displayed. TAB-1 is displayed small.

  In addition, a product registration tab (area) TAB-1, which is not a registration target, shows a corresponding transaction state. In FIG. 15, "No2 cash register" is displayed on the product registration tab (area) TAB-1, and a transaction (payment processing) is performed in the transaction corresponding to the product registration tab (area) TAB-1. To the effect.

  The product registration tab (area) is additionally displayed one by one each time the transaction increases by one, and when the transaction ends, the product registration tab (area) is deleted each time. Note that a registration order number such as “1”, “2”, or “3” may be displayed instead of a symbol of an arbitrary animal. The registration order number indicates, for example, the order in which registration of commodities was started.

  An image GA01 and an image GA02 are displayed at the lower left of the product registration sheet to which the product registration tab (area) TAB-2 of "cow" is attached, and a subtotal button BT10 and a pause button BT11 are displayed at the lower right of the product registration sheet. 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 the registration information transmitted to another POS terminal (the second POS terminal 20-2 or the third POS terminal 20-3). The 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 subplanning plane as shown in FIG. 14 is displayed. When the recall button BT27 is operated, the registration information of the transaction 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, a product registration sheet of a product registration tab (area) TAB-1 is displayed. At this time, the product registration tab (area) TAB-2 is displayed small. “Registering” is displayed on the product registration tab (area) TAB-2, indicating that a transaction corresponding to the product registration tab (area) TAB-2 has been registered.

  The settlement screen is displayed on the second POS terminal 20-2 to which the registration information has been transmitted. The payment screen is the same screen as the payment screen (payment method selection screen) displayed when the payment processing in the full self mode shown in FIG. 12A is started. 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 the settlement process according to the procedure displayed on the customer-side display unit 205. During the settlement process, before the end (receipt) button BT40 shown in FIG. 12C is operated (pressed), the recall button BT27 shown in FIG. By performing the operation (pressing), the registration information transmitted to the second POS terminal 20-2 is called back 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 purchase of the product can be performed. . Specifically, FIG. 17 shows the display contents of a registration screen in a scene where three items of goods (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. The total button BT20 is displayed on the sub-planning plane shown in FIG. 18, similarly to the sub-planning plane shown in FIG. In addition, after the registration information is recalled, the first POS terminal 20-1 shifts to the normal mode, so that the first cashier button BT21, the second cashier button BT22, and the check button BT25 shown in FIG. 14 are displayed. Not done. By operating the total button BT20, the deposit amount is input.

  Further, when a new transaction is started while 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. The symbol “koala” is displayed on the product registration tab (area) TAB-3. Here, a state is shown in which transaction registration on the product registration tab (area) TAB-1 is being performed.

  Also, when recalling the registration information, the recall of the registration information is disabled when the POS terminal (first POS terminal 20-1) is in a state in which the settlement process cannot be performed. The state in which the payment processing cannot be performed in the POS terminal includes, for example, near end, near full, out of receipt, failure of the change machine 209 and the printing unit 213, and the like. In determining near-end, near-full, out-of-receipt, and the like, for example, a threshold value or the like may be provided for each of them. In this case, even if the recall button BT27 shown in FIG. 15 is operated, the transaction registration information of 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 when the registration information cannot be recalled due to the near end. As specific error information, a message image GA20 including a message "Change is insufficient. Recall is not possible" is displayed to inform the clerk that recall is not possible. In this case, for example, the settlement can be performed by transmitting the registration information to the POS terminal (the second POS terminal 20-2) that has recalled the registration information or another POS terminal (for example, the third POS terminal 20-3). it can.

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

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

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

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

Step S301: It is determined whether or not the recall button has been operated. Specifically, it is determined whether or not an operation of pressing the recall button BT27 shown in FIG. 15 has been performed. If the recall button has not been operated, the process of step S301 is repeated. If the recall button BT27 has been operated, the process proceeds to step S302.
Step S302: It is determined whether there is a status error. Specifically, it is determined whether or not there is a status error such as a near end, a near full, an inability to receive or receive money due to a failure of the change machine 209, and an inability to issue a receipt due to an out of receipt or a failure in 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 unpaid transactions other than the transaction for which the registration process is currently being performed. The recall candidate is transaction registration information of a product registration tab (region) other than the product registration tab (region) of the transaction currently being registered, among the product registration tabs (regions) shown in FIG. Therefore, when there are a plurality of product registration tabs (regions) other than the product registration tabs (regions) of the transaction for which registration processing is currently being performed, there are a plurality of recall candidates. In the example illustrated 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 performed ( Since only the product registration tab (area) TAB-1), there is only one recall candidate. Further, as shown in FIG. 19, there are a plurality of (two) 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 performed. In some cases (product registration tab (area) TAB-2, product registration tab (area) TAB-3), a product registration tab (area) other than the product registration tab (area) of the transaction for which registration processing is currently being performed The store clerk selects and operates one of (product registration tab (area) TAB-2 and product registration tab (area) TAB-3).

Step S304: It is determined whether or not a product registration tab (area) has been operated. If there are multiple pieces of registration information of transactions that are candidates for recall, multiple product registration tabs (areas) for the corresponding transaction are displayed. From the product registration tab (area), register products for the transaction to be recalled. The clerk operates the tab (area). If there is an operation on the product registration tab (area), 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: The call back information is transmitted to the POS terminal which is performing the transaction settlement processing. When the number of product registration tabs (areas) other than the product registration tab (area) of the transaction for which the registration processing is currently being performed is singular, the call is returned to the POS terminal 20 that performs the transaction settlement processing of the product registration tab (area). Submit information. For example, when the recall button BT27 is transmitted on the screen shown in FIG. 15, the recall information is transmitted to the No2 cash register (the second POS terminal 20-2). When there are a plurality of product registration tabs (regions) other than the product registration tabs (regions) of the transaction for which the registration process is currently being performed, the POS for performing the transaction settlement process of the product registration tabs (regions) operated in step S304. The 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 cash 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 transmitted the call back information. Here, it is determined whether or not the returned registration information has been received. If the returned registration information has been 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 has transmitted the recall information is received, the product registration tab (region) corresponding to the registration information is changed to a product registration tab (region) TAB-1 shown in FIG. And a product registration sheet. The product registration tab (area) displayed large at this time is displayed small like a product registration tab (area) TAB-2 shown in FIG. 16, and the product registration sheet is a newly displayed product registration sheet. Position it on the back side. Further, the operation mode of the first POS terminal 20-1 which has been in the full self mode shifts to the normal mode. Then, the flowchart of FIG. 22 ends.

Step S308: Error content is displayed. The content of the status error when it is determined in step S302 that there is 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 of the customer-side display unit 205 in the POS terminal 20 (second POS terminal 20-2) when transmitting the registration information and recalling the transmitted registration information from product registration will be described with reference to FIGS. Will be explained. 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 illustrates a state in which the settlement process has been advanced and the call back information has been transmitted from the first POS terminal 20-1 in the scene illustrated 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. As shown in FIG. 23, a message image GA31 including a message "Called back to No1 cash register" is displayed, and the customer is notified that the registration information has been called back to No1 cash register (first POS terminal 20-1). To inform.

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

  On the coin withdrawal button BT51, a message of "coin only refund" is displayed. When the coin withdrawal button BT51 is operated, only coins of the deposited money are refunded. Is transmitted to the first POS terminal 20-1 together with the registration information. A message of “Payment of only banknotes” is displayed on the banknote withdrawal button BT52, and when the banknote withdrawal button BT52 is operated, only the banknotes of the deposited money are refunded, and for the deposited coins, 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 full deposit is refunded. A message of "full amount" is displayed on the full amount maintenance button BT54, and when the full amount maintenance button BT54 is operated, information on the full amount deposited is transmitted to the first POS terminal 20-1 together with 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 payment is made, the image shown in FIG. The image shown at 25 is displayed.

  FIG. 25 is 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 “Please return to the No. 1 cashier” is displayed on the customer side display unit 205 of the second POS terminal 20-2. An OK button BT61 displaying "OK" is displayed on the message image GA41. When the customer is performing the payment process at the second POS terminal 20-2, the customer returns to the first POS terminal 20-1 by watching the message image GA41 and operating the OK button BT61. Note that a clerk call button may be provided in addition to the OK button BT to call the clerk. By calling the clerk, the customer can check the change contents and the subsequent processing without leaving the vicinity of the second POS terminal 20-2.

  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 of the second POS terminal 20-2. Note that, 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, several 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. When the registration information of the next transaction has been transmitted to the second POS terminal 20-2, the transaction screen for the next transaction is started without shifting to the full self mode, and the transaction processing for the next transaction is started. Is done.

  In the first POS terminal 20-1, if the current customer is being registered, the first POS terminal 20-1 may call back after the processing is completed, or “temporarily suspend” the current customer's registration and register the previous customer's registration data. May be corrected, but when temporarily suspended, the merchandise registration tab (area) in which the merchandise of the previous customer has been registered remains until the settlement of the previous customer is completed. At this time, the clerk may perform the recall operation by touching the product registration tab (area) of the previous customer. Also, at that time, "Recall operation. Are you sure you want to display a confirmation screen such as (Yes / No) or only an (OK) screen. If you first suspend the registration operation of the customer, The recall may be performed without displaying the confirmation screen, whereby the recall operation can be easily performed and an operation error can be avoided.

  Next, processing in the second POS terminal 20-2 when the call back information of the registration information is transmitted from the first POS terminal 20-1 during the settlement process in the semi-self mode will be described. FIG. 26 is a flowchart illustrating 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 has been received from the first POS terminal 20-1. If the registration information has not been received, the process of step S401 is repeated, and if the registration information has been received, the process proceeds to step S402.
Step S402: Display a settlement screen. 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 the 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 settlement process proceeds, and the end (receipt) button BT40 shown in FIG. 12C is operated. Is determined. If the end (receipt) button BT40 has not been operated, the process proceeds to step S404. If the end (receipt) button BT40 has been operated, the process proceeds to step S412.
Step S404: It is determined whether or not 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 has been received, the process proceeds to step S405. If the call back information has not been received, the flowchart in FIG. 26 ends.

Step S405: Return the registration information. Here, the second POS terminal 20-2 returns the registration information received in Step S401 to the first POS terminal 20-1.
Step S406: Display a settlement screen (call back notification screen). Here, the 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: Display a settlement screen (a deposit refund inquiry screen). Here, a deposit refund inquiry screen including the message image GA32 shown in FIG. 25 is displayed.
Step S408: Execute processing corresponding to the operated button. Specifically, when any one of the coin withdrawal button BT51, the bill withdrawal button BT52, the full withdrawal button BT53, and the full withhold button BT54 included in the message image GA32 shown in FIG. 25 is operated, the processing corresponding to the operation is executed. I do. When the coin withdrawal button BT51 is operated, the coins of the deposited money are refunded, and information on the amount of the bill is transmitted to the first POS terminal 20-1 together with the registration information. When the bill withdrawal button BT52 is operated, the bill of the deposited money is repaid, and the information on the amount of the coin is transmitted to the first POS terminal 20-1 together with the registration information. When the full refund button BT53 is operated, the full amount of the deposited money is refunded. When the full amount maintenance button BT54 is operated, the information of the full amount paid is transmitted to the first POS terminal 20-1 together with the registration information.

Step S409: Move instruction display is performed. After one of the coin withdrawal button BT51, the bill withdrawal button BT52, the full payment 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. If the OK button BT61 shown in FIG. 25 has been operated, the process proceeds to step S411. If the OK button BT61 has not been operated, the process of step S410 is repeated.

Step S411: Display a registration start screen (full self mode). Here, the second POS terminal 20-2 is shifted to the full self mode, and a start screen of the full self mode 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. Therefore, the second POS terminal 20-2 receives the settlement completion information from 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 and transmits the registration information. The registration information can be called back from the POS terminal 20 (for example, the second POS terminal 20-2) that performs the settlement 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 is in a state where payment cannot be made, for example, when a status error has occurred, recall cannot be performed. You can recall. For this reason, even if the registration information is recalled, the registration information is not recalled when the settlement cannot be performed, so that a decrease in the operating efficiency of the first POS terminal 20-1 and the second POS terminal 20-2 is suppressed and the plurality of POS terminals are reduced. 20 can be operated efficiently.

  Further, since the settlement 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 settlement possible state of the first POS terminal 20-1 can be accurately determined. As a result, the plurality of POS terminals 20 can be operated efficiently.

  Further, according to the present embodiment, when the second POS terminal 20-2 recalls 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. Then, the screen displayed after the registration information is recalled is the registration start screen of the full self mode. Therefore, the second POS terminal 20-2 operating in the semi-self mode can be used in 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 clerk manually performing the mode switching process. 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 started by the second POS terminal 20-2 quickly. Therefore, the second POS terminal 20-2 can be used efficiently after the registration information is recalled.

  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 clerk near the second POS terminal 20-2, the second POS terminal 20-2 to which the registration information has been moved can be quickly operated only by the customer. Therefore, since the second POS terminal 20-2 can be operated at the same time when 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 the registration information to the first POS terminal 20-1 according to the call back information transmitted from the first POS terminal 20-1. Therefore, information can be exchanged between the first POS terminal 20-1 and the second POS terminal 20-2, so that the registration information can be corrected smoothly.

  Further, the POS terminal 20 includes a change machine 209 into which cash is put. When the second POS terminal 20-2 receives the recall information from the first POS terminal 20-1, the cash received is refunded. For this reason, at the time of performing the settlement after the registration information is recalled, miscalculation of money can be suppressed even if a product is purchased or canceled.

  When the second POS terminal 20-2 receives the recall information from the first POS terminal 20-1, the second POS terminal 20-2 refunds the banknote out of the deposited cash and transmits information on the amount of money to the first POS terminal 20-1. are doing. For this reason, at the time of performing the settlement after the registration information is recalled, if there is a purchase or cancellation of a product, it is possible to reduce a fear of losing a bill or the like.

  When the second POS terminal 20-2 receives the recall information from the first POS terminal 20-1, the second POS terminal 20-2 refunds the coins among the deposited cash and transmits information on the amount of the bill to the first POS terminal 20-1. are doing. For this reason, since the trouble of re-depositing the same bill once deposited can be saved, the deposit operation, particularly the bill deposit operation, can be simplified.

  Further, 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 transmits the received cash information together with the registration information to the first POS terminal 20-1. For this reason, it is possible to save the trouble of re-depositing the money once deposited, thereby simplifying the deposit operation. In addition, since there is no cash refund, it is possible to prevent forgetting to receive the paid out cash.

  In the above example, the POS system 1 includes the first POS terminal 20-1, the second POS terminal 20-2, and the third POS terminal 20-3, but includes two POS terminals. Or a device provided with four or more POS terminals. Further, the POS system 1 includes the store controller 10 other than the POS terminal 20. However, 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 the registration information, after operating the recall button BT27, if there are a plurality of recall candidates, the user selects the registration information to recall by operating the product registration tab. However, the registration information to be recalled in another manner may be selected. For example, by operating the recall button BT27, an unpaid process list screen including a list of unregistered transaction registration information in another POS terminal 20 is displayed, and recall is performed from the displayed list of registered information. May be selected. This list may include the registration information of the transaction being registered in addition to the unregistered registration information. In addition, the registered information that has been settled may be displayed in a different display mode from the registered information that has not been settled, for example, by changing the background color and design, the color and size of the characters, the font, and the like. When the registration information to be recalled is selected from the unpaid 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, in the case other than the first POS terminal 20-1, in this case, when there is a clerk at the third POS terminal 20-3, the recall can be performed not only with the registered device.

  In the above example, the first POS terminal 20-1 that has performed the registration process recalls the registration information from the second POS terminal 20-2, so that the registration information moves. However, another mode may be used. For example, when the registration information is transmitted from the first POS terminal 20-1 that has performed the registration processing to the second POS terminal 20-2, and the second POS terminal 20-2 attempts to perform the settlement processing, the second POS terminal 20-2 transmits the registration information to the second POS terminal 20-2. The transmitted registration information is transmitted to another POS terminal 20, for example, the second POS terminal 20-2, and the registration information is transmitted from the second POS terminal 20-2 to the third POS terminal 20-3. −3 may be moved.

  In the above example, the first POS terminal 20-1 that has 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. After transmitting the registration information, the registration information or a copy thereof may be stored. Further, a part of the registration information or a copy thereof may be stored. A part of the registration information returned from the second POS terminal 20-2, for example, only the transaction number may be returned. The transmission and reception of information is not limited to those directly transmitted and received between the transmission destination and the reception destination, and can be performed between the transmission destination and the reception destination even through another device, for example, the store controller 10. Transmission and reception.

  Further, in the above example, the recall is determined based on the status information, but the recall may be determined based on other conditions. For example, when the first POS terminal 20-1 has a payment machine for performing payment with a credit card or electronic money, the first POS terminal 20-1 may be configured to be able to call back, or the credit card displayed on the button shown in FIG. After the payment by electronic money or electronic money is determined, the first POS terminal 20-1 may be recalled when the credit card or electronic money used for these settlement methods can be used. Or you may make it recallable unconditionally.

  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 payment process can be sequentially performed. . In this case, one POS terminal 20 may store a plurality of registration information, or a plurality of POS terminals may store the registration information.

  In this case, when the POS terminal 20 for recalling the registration information is selected, the display of the color, the shape, the design of the animal, etc. of the product registration tab (area) TAB may be displayed for each POS terminal. For example, in the merchandise registration of the first POS terminal 20-1 in which registration information on the transaction first transmitted to the second POS terminal 20-2 is described, the color 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. ), The background may be all blue.

  Further, the color or the like may be changed for each registered tour 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 transaction transmitted first is yellow, and the registration information of the transaction transmitted second is green in the product registration tab (area). May be entered in the product registration sheet marked with. Instead of the same color or the like, a similar or similar color or the like may be used. For example, the registration information stored in the second POS terminal 20-2 is a red-based color such as red, orange, vermilion, and pink, and the registration information stored in the third POS terminal 20-3 is blue, green , Light blue, bluish purple and the like.

  If the second POS terminal 20-2 can store a plurality of pieces of registration information, and the plurality of pieces of registration information are stored, and if the registration information of the transaction currently being settled is called back, the full POS mode is set. Alternatively, the semi-self mode may be maintained without shifting to. In other words, when the second POS terminal 20-2 detects the reply of the registration information, the second POS terminal 20-2 determines whether or not the registration information is stored. Is maintained in the semi-self mode. In this case, the payment processing of the already stored registration information can be performed smoothly, so that the POS terminal can be operated efficiently. Further, when the registration information is recalled, the second POS terminal 20-2 may be in a standby state to wait for correction of the recalled registration information. In this case, the customer does not move from the second POS terminal 20-2, and waits for the registration information to be transmitted again. As described above, a selection screen may be displayed on the customer-side display unit 205 so that the customer can select whether to enter the standby mode or to shift to the full self mode. In addition, when the registration process or the settlement process is performed in the full self mode, if the registration information is not stored after the settlement process is completed, the process may shift to the semi-self mode. In this case, even if the registration information is not stored, for example, after the settlement process in the full self mode is completed, if the next customer is waiting to start the registration process in the full self mode, the semi-self mode May be prohibited. In order to prohibit the transition to the semi-self mode in this case, for example, the transition to the semi-self mode may be performed after a lapse of a predetermined time, for example, 10 seconds, after the processing in the full self mode is completed, The transition to the semi-self mode may be prohibited when the next customer is detected by the human sensor.

  Further, the POS terminal 20 may store, as unregistered registration information, the registration information of the transaction transmitted from the other POS terminal 20 to the other POS terminal 20. For example, when the first POS terminal 20-1 transmits the 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 the information. . In this case, for example, the third POS terminal 20-3 may transmit the collection 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 recall or pick-up. In addition, the unpaid registration information moved between a plurality of POS terminals 20 can be represented as unpaid information in all POS terminals 20 by a product registration tab (area) or displayed as a list of unpaid products. Or it may be made to be.

  Further, 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. A mode registration start screen is displayed, but the mode may shift to another mode. For example, the mode may shift 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 the screen displayed first in the normal mode or the double scan mode. In addition, 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 the first screen displayed in the semi-self mode.

  Further, in the above example, when the first POS terminal 20-1 is in the settlement impossible state, the registration information cannot be recalled, and when the settlement is possible, the registration information can be recalled. May be made to be able to recall the registered information even when the account is in a state where payment cannot be made. In this case, the first POS terminal 20-1 transmits new registration information of the transaction including the recalled registration information to another POS terminal (the second POS terminal 20-2 and the third POS terminal 20-3, etc.). It is preferable that the settlement process is performed. In this case, the POS terminal 20 that transmits the new registration information may be the POS terminal 20 from which the registration information has been recalled, or the POS terminal 20 that transmits the new registration information may be specified (selected) again. The selection in this case may include the own device. When transmitting new registration information to the POS terminal 20 from which the registration information has been recalled, the customer receives new registration information while staying near the POS terminal 20 (for example, the second POS terminal 20-2). It may wait for it to come, or move to the POS terminal 20 (for example, the first POS terminal 20-1) that performs the registration process, and then move to the POS terminal (for example, the second POS terminal 20-2) that performs the settlement again You may make it. In the case of a mode in which the POS terminal 20 for transmitting the registration information is specified again, the customer can, for example, change the POS terminal (for example, the second POS terminal 20-2) from the recalled 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 to move to a designated POS terminal (for example, the third POS terminal 20-3) to perform the settlement process.

  Further, in the above example, when the registration information is recalled during the settlement-only mode, the POS terminal (the second POS terminal 20-1) that shifts to the full self mode is the normal mode, the full self mode, the semi self mode, And a double scan mode, but the other modes need not be provided as long as they have a semi-self mode and a full self mode. The POS terminal 20 has operation modes 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 does not have an operation mode and performs at least one of a registration process and a settlement process. In this case, there is no clear concept of the operation mode, but the provided information and the processing of the clerk provide at least a part of the function equivalent to the function of the POS terminal 20 in the above example. Is also good.

  Further, in the above example, recalling is performed in the event of a status error such as a near end, a near full, an inability to receive or receive money due to a failure of the change machine 209, or an inability to issue a receipt due to an out of receipt or a failure in the printing unit 213. Although it is made impossible to recall, if any of these occur, recall may not be made. Further, it may be possible to determine whether or not recall can be performed according to the status of each status. For example, recall may or may not be possible depending on the type of money even at the near end.

  Further, in the above example, the recall of the registration information can be performed even when the settlement processing is performed by the first POS terminal 20-1, but when the settlement processing is performed by the first POS terminal 20-1, the registration information is recalled. May not be recalled. In this case, it is possible to reduce the concern that the settlement process is complicated. As a result, the plurality of POS terminals 20 can be operated efficiently.

  Further, in the above example, when the registration information is recalled in the state where the payment is made in the second POS terminal 20-2 during the settlement, the refund of the deposited money is performed in full amount, only the bill, and only the currency. And the like can be selected, but these may be determined in any mode and may not be selected. In addition, when there is an option that cannot be selected, for example, when there is an option to refund only the banknote without depositing the banknote, the button for the option that cannot be selected is not displayed or displayed in a grayed-down state Then, the customer may not be able to select.

  Further, 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 mode. For example, the registration information may be moved by writing the registration information in a code attached to the medium and moving the medium like a shopping ticket.

  Further, in the above example, the POS terminal performing the recall transmits the recall information. However, another POS terminal 20 or the store controller 10 may transmit the recall information. For example, regarding the registration information transmitted from the first POS terminal 20-1 to the second POS terminal 20-2, a call is made from the store controller 10 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 from the POS terminals 20 and the like other than the third POS terminal 20-3. May be transmitted from another POS terminal 20 or the store controller 10 instead of transmitting the payment information.

  Further, 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 another POS terminal. . For example, it may include a POS terminal that can perform a registration process and cannot perform a payment process, or may include a POS terminal that cannot perform a registration process and can perform a payment process. These POS terminals may be provided in place of the POS terminal 20 that can perform both the registration process and the settlement process.

  Further, 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, but some POS terminals 20 cannot be transmitted. You may. For example, the POS terminal 20 that cannot be transmitted may be set to be unable to transmit when a status error, for example, a situation such as near-end, near-full, or out of receipt has occurred. Also, transmission may be disabled when the number of pieces of registration information that can be registered in the POS terminal 20 is at the 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 and the like. In the case of the POS terminal 20 in the full self mode or the settlement mode, transmission may be disabled when another customer is performing an operation. The condition of the POS terminal 20 for disabling transmission of registration information and the condition of the POS terminal 20 for disabling recall may be common or different.

  In the above example, a receipt or a receipt (receipt or the like) is issued when the settlement is completed. However, for example, a receipt (receipt) unnecessary button is provided to omit the issuance of the (receipt or the like). You may be able to. The receipt (receipt) unnecessary button may be provided on the customer side display unit 205 or the clerk side display unit 210, for example. Further, the key operation unit 211 may be provided. By making it possible to omit issuance of a receipt (such as a receipt), it is possible to contribute to a reduction in receipt paper.

  When omitting issuance of (receipt or the like) printed on a paper medium such as a receipt paper, an electronic receipt may be issued instead of (receipt or the like). In this case, for example, an electronic receipt may be automatically issued instead of (a receipt or the like) by performing user registration in advance and inputting user identification information (member number) or the like, or a receipt or the like. The customer may be allowed to select which of the electronic receipt and the electronic receipt is to be issued. Alternatively, both a receipt or the like and an electronic receipt may be issued. In this case, the selection screen may be displayed to allow the customer to make a selection, or the selection screen may be omitted by, for example, registering a selection pattern for each user in advance. As an issuance mode of the receipt or the like, for example, it may be possible to select from non-issuing, only a paper medium, only an electronic receipt, and both a paper medium and an electronic receipt. The selection screen in this case may be provided in at least one of the customer display unit 205, the clerk display unit 210, and the key operation unit 211. At this time, a receipt or the like may be issued at the same time as the change is issued. When dispensing change and issuing a receipt or the like, a receipt or the like may be issued after dispensing the change, or the change may be paid after issuing the receipt or the like. When a receipt is issued, the customer may pay out the change after receiving the receipt to prevent the customer from 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 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, but may be, for example, a full self mode. By waiting in the full self mode, a plurality of POS terminals 20 can be used efficiently. When the waiting time at the cash register at the first POS terminal 20-1 increases, the 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 settle the payment mode. Can be operated as Alternatively, the registration information in the transaction for which the registration processing 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 processing. You may. For example, when the second POS terminal 20-2 is to take over the settlement 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, and 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.

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