(Overview of each operation mode)
Subsequently, the operation mode of the POS terminal 20 will be described. The POS terminal 20 has a plurality of operation modes. Specifically, the POS terminal 20 has at least three types of operation modes (normal mode, full self mode, and semi-self mode).

The above-mentioned operation mode is an operation mode during normal work (operation mode related to registration processing and settlement processing), and is an aggregation mode for totaling and inquiring sales, sales, etc., and setting work by a clerk, maintenance staff, etc. It does not include maintenance mode for maintenance work, training mode for newcomers to train, etc.

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

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

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

In the normal mode, the clerk registers the customer's purchased product on the clerk side (the clerk side scanner unit 212, the clerk side display unit 210, the key operation unit 211). That is, the POS terminal 20 executes the registration process of the purchased product by the operation of the clerk (scanning by the clerk side scanner unit 212, touching the clerk side display unit 210, operating the key operation unit 211) (FIG. 5 (A). ) Upper row).

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

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

The customer may wait until the registration process by the clerk is completed (until the total amount is fixed), but may insert cash into the change machine 209 before the registration process is completed. That is, the POS terminal 20 can accept payment during the registration process (upper part of FIG. 5A).

In addition, the customer may select a payment method (also referred to as a payment type, a payment method, or a payment type) before the registration process is completed. That is, the POS terminal 20 can accept the selection of the payment method during the registration process (details will be described later).

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

In addition, the POS terminal 20 controls the payout of change / fishing bills by the change machine 209 in order to prevent forgetting to take the change when there is change, and a sensor or the like that the customer has removed the change / fishing bill. The issuance of the receipt by the printing unit 213 may be controlled after recognizing the above. The same applies to other operation modes.

Further, in the normal mode, the registration process is executed on the clerk side as described above, and the settlement process is executed on the customer side of the own terminal using the registration information generated in the registration process (see FIG. 5). In addition, the clerk executes the registration process and transmits the registration information generated in the registration process to another terminal (another terminal capable of executing the settlement process, for example, another POS terminal 20) (via LAN11). , Send directly to another terminal, or send to another terminal via the store controller 10 or a monitoring terminal (not shown). The same shall apply hereinafter), and the registration information generated in the registration process is coded (bar). It is also possible to execute the process of converting into a code (two-dimensional code, etc.), 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 the own terminal and making a payment at the own terminal, and a function of registering a product in the own terminal and making a payment in another terminal.

The above-mentioned function of registering a product on the own terminal and making a payment on another terminal is an original function of the semi-self mode. Semi-self mode is classified into registration-only mode and accounting-only mode. The POS terminal 20 in the semi-self mode (registration-only mode) has a function of registering a product on its own terminal and making a payment on another terminal. Specifically, the POS terminal 20 in the semi-self mode (registration-only mode) executes the registration process on the clerk side and transmits the registration information generated in the registration process to another terminal (or is generated in the registration process). Code the registration information, etc., print it on the medium, and issue it as an accounting ticket). The POS terminal 20 in the semi-self mode (accounting-only mode) has a function of settling products registered in other terminals. Specifically, the POS terminal 20 in the semi-self mode (accounting-only mode) receives the registration information transmitted from the POS terminal 20 in the semi-self mode (registration-only mode) (or the POS in the semi-self mode (registration-only mode)). Read the checkout ticket issued by the terminal 20) and execute the settlement process.

The POS terminal 20 in the normal mode has a function of registering a product on its own terminal and making a payment on another terminal, like the POS terminal 20 in the semi-self mode (registration-only mode), but the POS terminal 20 in the full self mode. (The same applies to the POS terminal 20 in the normal mode), like the POS terminal 20 in the semi-self mode (accounting-only mode), may have a function of settling the products registered in other terminals. That is, the full self mode POS terminal 20 and the normal mode POS terminal 20 receive registration information from other terminals (semi-self mode (registration-only mode) POS terminal 20, normal mode POS terminal 20, etc.) (or You may read the accounting ticket) and execute the settlement process.

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

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

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

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

In the full self mode, as described above, the customer side executes both the registration process and the settlement process, but the clerk side does not mean that nothing can be done. That is, even when the POS terminal 20 is operating in the full self mode, for example, the clerk side scanner unit 212 scans the clerk code, displays various information, and registers products. It is possible. The state in which the registration process is executed on both the clerk side and the customer side (operation mode) may be referred to as a double scan mode.

(Notification of operation mode)
Each POS terminal 20 may notify the current operation mode of its own terminal. For example, each POS terminal 20 may display the current operation mode of its own terminal on the clerk side display unit 210. Specifically, each POS terminal 20 displays a screen having an operation mode display field of the own terminal on the clerk side display unit 210, and displays the current operation mode of the own terminal in the operation mode display field on the screen. You may. Further, each POS terminal 20 displays a screen on which an image (for example, a button-like image) corresponding to each operation mode is arranged on the clerk side display unit 210, and corresponds to the current operation mode of the own terminal on the screen. The image to be displayed may be displayed in a display mode different from that of the image that does not correspond to the current operation mode (for example, a display mode that is more conspicuous than the display mode of other images). For example, the normal mode image and the full self mode image are always displayed, and when the current operation mode of the own terminal is the normal mode, the normal mode image is displayed in a display mode that is more conspicuous than the full self mode image, and the own terminal is displayed. When the current operation mode of is the full self mode, the full self mode image may be displayed in a display mode that is more conspicuous than the normal mode image. In addition, each POS terminal 20 may also display the current operation mode of its own terminal on the customer side display unit 205.

Further, each POS terminal 20 may notify the current operation mode of another terminal in place of or in addition to the current operation mode of the own terminal. That is, each POS terminal 20 may notify the current operation mode of the other terminal by recognizing each other's current operation mode of the other terminal. As an example of the method in which each POS terminal 20 recognizes the current operation mode of another terminal, each POS terminal 20 notifies the other terminal of the operation mode (latest operation mode) after the transition to the operation mode (LAN11). This is a method of directly notifying other terminals via the store controller 10 or notifying other terminals via a store controller 10 or a monitoring terminal (not shown). Further, each POS terminal 20 may notify the current processing status of the other terminal as well as the current operation mode of the other terminal.

Further, each POS terminal 20 may notify information according to the current operation mode and the like (operation mode, processing status, etc.) of the own terminal. For example, each POS terminal 20 sends a predetermined message (for example, see FIG. 7A) to the customer side display unit 205 when the current operation mode of the own terminal is the full self mode, for example, when waiting. It may be displayed. Further, the POS terminal 20 may notify the information according to the current operation mode of another terminal or the like in place of or in addition to the information according to the current operation mode of the own terminal.

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

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

Further, since the mode switching button 211a is arranged at the upper right corner (topmost and rightmost) of the key operation unit 211, the mode transition operation is performed not only when the clerk is on the clerk side but also when the clerk is on the customer side. You will be able to do it. That is, the clerk on the customer side cannot normally see each button of the key operation unit 211, but the mode switching button 211a existing at the upper right end of the key operation unit 211 is reached out from the customer side and groped. Since the mode switching button 211a, which is the operation target, can be easily recognized only by (feeling of the hand), the clerk on the customer side can perform the mode transition operation without moving to the clerk side.

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

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

Further, the operation mode of the POS terminal 20 shifts according to an operation other than the explicit mode shift operation by the clerk (for example, reading the clerk code). In addition, the POS terminal 20 has predetermined conditions (conditions related to time such as elapsed time and predetermined time (schedule), commands with other terminals (POS terminal 20, monitoring terminal), etc., which do not depend on the operation of the clerk, etc. The operation mode shifts based on the conditions related to the transmission and reception of information in. As described above, when the operation mode is shifted in the own terminal, the operation mode after the shift may be notified to another terminal.

In the following description, it is assumed that the POS terminal 20-1 and the POS terminal 20-2 are in the normal mode. Further, it is assumed that the POS terminal 20-3 is in the full self mode.

FIG. 10A is a display example on the clerk side display unit 210 of the POS terminal 20-1 in the normal mode. Specifically, FIG. 10A shows a case where one item (canned beer) is registered and the payment method has not been decided yet (when the payment method has not been decided and cash has not been input). Shows the display contents of the registration screen of. That is, when the canned beer is registered by the clerk from the state where the POS terminal 20-1 displays the registration screen (registration screen in the initial state) of FIG. 9A on the clerk side display unit 210, the clerk side. A registration screen as shown in FIG. 10A is displayed on the display unit 210.

In FIG. 10A, the subtotal button BT10 at the lower right of the screen is a button for instructing the end of product registration. The clerk operates (touches) the subtotal button BT10 after the product registration is completed.

The 20-2 cash register button BT12 is a button for designating the 20-2 cash register (POS terminal 20-2). The clerk operates the 20-2 cash register button BT12 when designating the POS terminal 20-2 as the terminal for transmitting the registration information (including via the store controller 10; the same applies hereinafter). “(Normal)” indicated on the 20-2 cash register button BT12 indicates that the operation mode of the POS terminal 20-2 corresponding to the 20-2 cash register button BT12 is the normal mode.

The 20-3 cash register button BT13 is a button for designating the 20-3 cash register (POS terminal 20-3). The clerk operates the 20-3 cash register button BT13 when designating the POS terminal 20-3 as the terminal for transmitting the registration information. “(Full self)” indicated on the 20-3 cash register button BT13 indicates that the operation mode of the POS terminal 20-3 corresponding to the 20-3 cash register button BT13 is the full self mode.

The checkout button BT15 is a button for causing the printing unit 213 to issue a checkout ticket. The clerk operates the checkout button BT15 when the POS terminal 20 (the POS terminal 20 in which the customer has read the checkout) executes the process.

When comparing the POS terminal 20 in the normal mode and the POS terminal 20 in the full self mode as the POS terminal 20 to which the registration information is transmitted, the POS terminal 20 in the full self mode is better than the POS terminal 20 in the normal mode. Is preferable as a destination for transmitting registration information. Since the POS terminal 20 in the normal mode is basically operated by a clerk (see FIG. 5A), processing (for example, registration processing, customer support, etc.) continuously exists and is registered. Even if the information is sent, there is a high possibility that it cannot be processed immediately, and even if it is vacant (even if there is no clerk or customer), it is basically vacant to immediately respond to the customer who wants the support of the clerk. On the other hand, the full self-mode POS terminal 20 can transmit the registration information immediately if the customer is not attached, and even if the customer is attached, the POS terminal 20 may simply be processed in order as described above. This is because such a problem is unlikely to occur.

That is, in general, the POS terminal 20 in the normal mode is in the clerk use state, but the POS terminal 20 in the full self mode is in the clerk non-use state. If the registration information is transmitted to the POS terminal 20 in the normal mode in which the clerk is in use, the processing may be delayed and inefficiency may occur. Therefore, as the transmission destination of the registration information, the full self-mode POS terminal 20 in the clerk non-use state is more suitable than the POS terminal 20 in the normal mode in the clerk use state.

In view of the above, the store clerk is notified whether or not the POS terminal 20 as the destination of the registration information is preferable, or which is more preferable when there are a plurality of destinations of the registration information. As an example, in FIG. 10A, the outline portion of the 20-3 cash register button BT13 corresponding to the POS terminal 20-3 in the full self mode, which is relatively preferable as the transmission destination of the registration information, is shown by a solid line, and the transmission destination of the registration information is shown. The contour portion of the 20-2 cash register button BT12 corresponding to the relatively unfavorable normal mode POS terminal 20-2 is shown by a broken line. The above-mentioned notification by the contour portion is an example, and the clerk determines whether or not the POS terminal 20 as the destination of the registration information is preferable, or which is more preferable when there are a plurality of destinations of the registration information. The notification mode is not limited as long as it can be recognized. For example, if it is relatively unfavorable, the background color of the button may be grayed out, or a penalty mark or diagonal line may be added to the entire button. Further, the display size, shape, and display position of the button may be different depending on whether or not it is preferable as the POS terminal 20 to which the registration information is transmitted, and some information (“priority” or “recommended”” may be given to the button. You may attach a badge-like image, etc.

In view of the above, although details will be described later, there are cases where transmission of registration information to the POS terminal 20 in the normal mode in which the clerk is in use is prohibited (for example, the “No button BT22” in FIGS. 18 (A) and 18 (B). ”Is prohibited). If the transmission of the registration information to the POS terminal 20 in the normal mode in which the clerk is in use is prohibited, the processing can be performed efficiently as a whole without inefficiency.

Further, as will be described in detail later, the prohibition of transmission of registration information to the POS terminal 20 in the normal mode in which the clerk is in use may be lifted (for example, "button BT23" in FIG. 18 (A) and FIG. 18 (B). ) "Yes (payment only) button BT24" and "Yes (registration) button BT24" will be lifted). That is, when the registration information is not inefficient even if it is transmitted to the terminal in the clerk usage state, the registration information can be transmitted as appropriate, so that the processing can be performed efficiently. Alternatively, in the case where the registration information is not transmitted to the terminal in the clerk usage state, which is rather inefficient, the registration information can be transmitted as appropriate, so that the processing can be performed efficiently. In addition, when the registration information is not inefficient even if it is sent to the terminal in the clerk usage state, for example, the case where the clerk is attached but the registration information can be sent immediately can be processed, or the clerk actually For example, if is not attached. If you do not send the registration information to the terminal used by the clerk, it will be inefficient. For example, if you cannot settle the cash on your terminal due to a hardware or software failure or lack of change, the hardware If the receipt cannot be issued on your terminal due to a hardware or software failure or out of paper, a specific payment type (credit card payment, electronic money) is not supported due to a hardware or software failure or the payment is not supported. Settlement, etc.) cannot be settled.

(Explanation of the flowchart of FIG. 25)
At the start of the flowchart of FIG. 25, it is assumed that the POS terminal 20-1 is in a state in which no product has been registered yet, and neither cash has been input nor a payment type has been input. .. That is, at the start of the flowchart of FIG. 25, the registration screen (initial state registration screen) as shown in FIG. 9A is displayed on the clerk side display unit 210 of the POS terminal 20-1. It shall be.

Step S100: The POS terminal 20-1 determines whether or not the product has been scanned (scanned by the clerk-side scanner unit 212, touched by the clerk-side display unit 210). That is, the POS terminal 20-1 determines whether or not one item has been registered as a product. If the product is scanned or the like, the process proceeds to step S110. If the product has not been scanned, the process proceeds to step S128.

Step S110: The POS terminal 20-1 registers the scanned product. Then, the process proceeds to step S120.
Step S120: As shown in FIG. 10A, for example, the POS terminal 20-1 presses the subtotal button BT10, the send button (20-2 cash register button BT12, 20-3 cash register button BT13), and the checkout button BT15. indicate. Subsequently, the process proceeds to step S200 of FIG.

Step S128: The POS terminal 20-1 determines whether or not cash has been inserted into the change machine 209. If cash is inserted, the process proceeds to step S150. If no cash has been inserted, the process proceeds to step S130.
Step S130: The POS terminal 20-1 determines whether or not the payment type has been input. If the payment type is entered, the process proceeds to step S160. If the payment type has not been entered, the process proceeds to step S140.

Step S140: The POS terminal 20-1 determines whether or not the other terminal settlement reservation button has been operated. When the settlement reservation button of another terminal is operated, the process proceeds to step S170. If the other terminal settlement reservation button is not operated, the process returns to step S100.

Step S150: The POS terminal 20-1 records the inserted cash as a deposit. Then, the process proceeds to step S160.

Step S160: The POS terminal 20-1 prohibits transmission and the like (transmission of registration information, issuance of accounting tickets). Specifically, the POS terminal 20-1 is controlled so as not to display the send button (20-2 cash register button BT12, 20-3 cash register button BT13) and the checkout button BT15 after this step (step S160). .. For example, a flag to be referred to when determining display / non-display of each of the send button and the checkout ticket button BT15 may be provided, and the flag may be set to non-display in this step. The same applies to the subtotal button BT10 in step S170 below. Subsequently, the process proceeds to step S300 of FIG. 27 (A).

Step S170: The POS terminal 20-1 prohibits the settlement process at the terminal (POS terminal 20-1). Specifically, after this step (step S170), the POS terminal 20-1 is controlled so as not to accept cash input and payment type input, and is controlled not to display the subtotal button BT10. As a method of not accepting cash input, for example, the cash input port may not be opened mechanically. As a method of not accepting the input of the payment type, for example, in the mode of arranging the settlement reservation button of another terminal on the registration screen, the settlement reservation button of the other terminal may be deleted or invalidated (error notification etc. after operation). However, in the embodiment in which the other terminal settlement reservation button is arranged on the key operation unit 211, the other terminal settlement reservation button may be invalidated (error notification or the like after the operation). Subsequently, the process proceeds to step S500 of FIG. 28 (A).

(Explanation of the flowchart of FIG. 26)

Alternatively, the POS terminal 20-1 may transmit the registration information to the designated terminal (POS terminal 20-3 in the full self mode) together with the information (flag) indicating that the registration process is started.

Step S830: The POS terminal 20-1 determines whether or not it is selected not to transmit the registration information on the selection screen. For example, the POS terminal 20-1 determines whether or not the "not button BT22" has been operated on the small screen SG05 of FIG. 18 (B). If it is selected not to send the registration information, the process returns to step S800. If it is not selected not to send the registration information, the process proceeds to step S840.

Step S840: The POS terminal 20-1 determines whether or not it is selected to perform only the settlement process without performing the registration process on the selection screen. For example, the POS terminal 20-1 determines whether or not the "(payment only) button BT24" has been operated on the small screen SG05 of FIG. 18 (B). If it is selected to perform only the settlement process without performing the registration process, the process proceeds to step S845. If it is not selected to perform only the settlement process without performing the registration process, the process proceeds to step S850.

Step S845: The POS terminal 20-1 transmits the registration information to which the information (flag) to be started from the settlement process is added to the designated terminal (POS terminal 20-2 in the normal mode). Alternatively, the POS terminal 20-1 may transmit the registration information to the designated terminal (POS terminal 20-2 in the normal mode) together with the information (flag) indicating that the settlement process is started.

Step S850: The POS terminal 20-1 determines whether or not it is selected to perform the registration process on the selection screen. For example, the POS terminal 20-1 determines whether or not the "(register) button BT25" has been operated on the small screen SG05 of FIG. 18 (B). If it is selected that the registration process is also performed, the process proceeds to step S855. If it is not selected to perform the registration process, the process returns to step S830.

Step S855: The POS terminal 20-1 transmits the registration information to which the information (flag) to be started from the registration process is added to the designated terminal (specifically, the POS terminal 20-2 in the normal mode). Alternatively, the POS terminal 20-1 may transmit the registration information to the designated terminal (POS terminal 20-2 in the normal mode) together with the information (flag) indicating that the registration process is started.

(Prohibition and cancellation of transmission of registration information to POS terminal 20-2 in normal mode)
The POS system 1 of the present embodiment has been described above. According to the POS system 1 of the present embodiment, for example, the POS terminal 20-1 in the normal mode is destined for the POS terminal 20-2 in another normal mode. When transmitting the registration information, it is confirmed with the clerk on the transmitting side whether or not to transmit the registration information (FIGS. 18 (A), 18 (B), step S802 of FIG. 30, step S1802 of FIG. 31). , See step S2802 in FIG. 32 (A)).

That is, the POS terminal 20-1 prohibits (temporarily prohibits, temporarily prohibits) the transmission of registration information addressed to the POS terminal 20-2 in another normal mode. Further, the POS terminal 20-1 notifies that the transmission of the registration information to the other POS terminal 20-2 in the normal mode is prohibited.

Further, when the POS terminal 20-1 in the normal mode transmits the registration information to the POS terminal 20-2 in the other normal mode as the destination, the clerk on the transmitting side performs an operation to transmit the registration information in the above confirmation. In this case, the registration information is transmitted to the POS terminal 20-2 as the destination (see steps S845 and S855 in FIG. 30, step S2865 in FIG. 32 (A), and the like).

That is, the POS terminal 20-1 has released the prohibition of transmission of registration information destined for the POS terminal 20-2. More specifically, based on the fact that the clerk on the transmitting side has performed an operation to transmit the registration information after notifying that the transmission of the registration information to the other POS terminal 20-2 in the normal mode is prohibited. The above transmission prohibition has been lifted.

Further, when the POS terminal 20-1 in the normal mode transmits the registration information to the POS terminal 20-2 in the other normal mode as the destination, the POS terminal 20-2 which is the destination of the registration information is based on the registration information. The clerk on the sending side (the clerk logged in to the POS terminal 20-1) can select whether to perform the registration process or only the settlement process based on the registration information (FIG. 18 (B)). , Steps S845 and S855 in FIG. 30, steps S1845 and S1855 in FIG. 31 and the like). In addition, the POS terminal 20-2, which is the destination of the registration information, displays the selectability by the clerk on the transmitting side (that is, the content of the instruction to the clerk on the receiving side (the clerk logged in to the POS terminal 20-1)). (See FIGS. 20 (A) and 21 (A)).

That is, when the POS terminal 20-1 transmits the registration information to the other POS terminal 20-2 in the normal mode, another clerk (the clerk logged in to the POS terminal 20-2) together with the registration information. Instruction information (instruction information on how to process (only settlement, registration) the registration information. Special information (flag) in the present embodiment) is transmitted to.

(Prohibit execution of either payment on your own terminal or payment on another terminal)
Further, according to the POS system 1 of the present embodiment, the POS terminal 20-1 in the normal mode has other terminals (POS terminal 20-2, POS terminal 20) when cash is inserted into the change machine 209. The buttons (20-2 cash register button BT12, 20-3 cash register button BT13, checkout ticket button BT15) used for payment in -3) are hidden (FIG. 11 (A), step S160 in FIG. 25, See step S260 and the like in FIG. 26). The same applies to the case where the payment type is selected (see step S160 in FIG. 25, step S260 in FIG. 26, etc.).

That is, when the POS terminal 20-1 is to be settled on the own terminal (POS terminal 20-1), the POS terminal 20-1 is settled on another terminal (for example, while the registration process is being performed) before the actual settlement. The transmission of registration information to POS terminals 20-2 and POS terminals 20-3) is prohibited, and the issuance of bills is prohibited.

On the other hand, the POS terminal 20-1 in the normal mode issues a subtotal button BT10 used for payment on the own terminal (POS terminal 20-1) and an accounting ticket when a declaration is made by the transmission reservation button. The checkout button BT15 used in this case is hidden (see FIG. 23 (A)). In addition, the POS terminal 20-1 in the normal mode has a subtotal button BT10 used when making a payment at the own terminal (POS terminal 20-1) and another terminal when a declaration is made by the checkout ticket issuance reservation button. The send buttons (20-2 cash register button BT12, 20-3 cash register button BT13) used when transmitting the registration information to the user are hidden (see FIG. 24 (A)). Further, the POS terminal 20-1 in the normal mode hides the subtotal button BT10 used when making a payment on the own terminal (POS terminal 20-1) when there is a declaration by the other terminal settlement reservation button. (See FIG. 24B, step S170 in FIG. 25, step S270 in FIG. 26, and the like).

That is, when the POS terminal 20-1 is to be settled on another terminal (POS terminal 20-2, POS terminal 20-3), it is before the actual settlement (for example, while the registration process is being performed). In), payment at the own terminal (POS terminal 20-1) is prohibited.

Although the POS system 1 of the present embodiment has been described above, the data configuration, processing flow, display and output modes, and the like can be appropriately changed and modified.

For example, in the above embodiment, whether or not the POS terminal 20-1 in the normal mode transmits the registration information to the POS terminal 20-2 when transmitting the registration information to the POS terminal 20-2 in the normal mode as a destination. Is asked to the clerk on the transmitting side, but does the POS terminal 20-1 transmit the registration information to a terminal different from the POS terminal 20-2 (specifically, the POS terminal 20-3 in the full self mode)? You may want to ask the clerk on the sending side to confirm whether or not it is.

For example, on the small screen SG04 of FIG. 18 (A), in addition to the "not button BT22" and "yes button BT23", a "button to send to another device (POS terminal 20-3)" is arranged, and "another device (POS)" is arranged. When the "button to send to terminal 20-3)" is operated, the small screen SG04 is erased, and the settlement process is performed for the POS terminal 20-3 in full self mode instead of the POS terminal 20-2 in normal mode. Registration information may be sent to start with.

Alternatively, a "button to be transmitted to another device (POS terminal 20-3)" may be arranged instead of the "button BT23" on the small screen SG04 of FIG. 18 (A). That is, instead of arranging the "button BT23" on the small screen SG04, the "button BT22 not" and the "button to be transmitted to another device (POS terminal 20-3)" may be arranged. That is, the POS terminal 20-1 may prohibit the transmission of registration information destined for the POS terminal 20-2 in the normal mode.

Further, in addition to the "not button BT22", "yes (payment only) button BT24" and "yes (registration) button BT25" on the small screen SG05 of FIG. 18 (B), "another device (POS terminal 20-3)" "A button to send (settlement only)" and "a button to send (also register) to another device (POS terminal 20-3)" are arranged, and "send (settlement only) to another device (POS terminal 20-3)". When the "button" is operated, the small screen SG05 is erased and the registration information is sent to the POS terminal 20-3 in the full self mode instead of the POS terminal 20-2 in the normal mode so that the settlement process is started. When the "button to send (also register) to another device (POS terminal 20-3)" is operated, the small screen SG05 is erased and the full self mode is used instead of the normal mode POS terminal 20-2. Registration information may be transmitted to the POS terminal 20-3 of the above so as to start from the registration process.

Alternatively, instead of the "send (settlement only) button BT24" on the small screen SG05 of FIG. 18 (B), a "button to send (settlement only) to another device (POS terminal 20-3)" is arranged and "do (settlement only)". Instead of the "button BT25", a "button for transmitting (also registering) to another device (POS terminal 20-3)" may be arranged.

Further, in the above embodiment, whether or not the POS terminal 20-1 in the normal mode transmits the registration information to the POS terminal 20-2 when transmitting the registration information to the POS terminal 20-2 in the normal mode as a destination. Although the option of is given to the clerk on the transmitting side, the POS terminal 20-1 may simply prohibit the transmission of the registration information addressed to the POS terminal 20-2 without giving the option. For example, the POS terminal 20-1 does not display the small screen SG04 of FIG. 18 (A) or the small screen SG05 of FIG. 18 (B), but the small screen SG04 of FIG. 18 (A) or the small screen SG04 of FIG. 18 (B). The same control as when the "No button BT22" on the screen SG05 is operated may be performed. The POS terminal 20-1 may notify that the transmission of the registration information to the POS terminal 20-2 is prohibited.

Further, the POS terminal 20-1 in the normal mode has an option of whether or not to transmit the registration information to the POS terminal 20-2 in the normal mode as a destination, and when the registration information is transmitted to the destination, the registration is made at the destination. Whether or not to give an option of how to process the information (payment only, registration) may be different depending on the authority of the clerk on the sending side. For example, if the authority of the clerk on the sending side is high, the small screen SG05 in FIG. In addition, "a button to send (settlement only) to another device (POS terminal 20-3)" and "a button to send (also register) to another device (POS terminal 20-3)" are arranged and displayed on the transmitting side. If the authority of the clerk in FIG. 18 is medium, the small screen SG04 in FIG. 18 (A) and the small screen SG05 in FIG. 18 (B) are displayed, and if the authority of the clerk on the transmitting side is low, any option is selected. It may not be given (the transmission of registration information to the POS terminal 20-2 in the normal mode may be prohibited).

Further, in the above embodiment, the POS terminal 20-2 in the normal mode, which is the destination of the registration information, gives the clerk on the receiving side an option of whether or not to process the registration information in the own terminal (POS terminal 20-2). Although the case of giving is also explained (see FIGS. 20 (A), 21 (A), etc.), whether or not to give the option to the clerk on the receiving side may be different depending on the authority of the clerk on the receiving side. Good. For example, if the authority of the clerk on the receiving side is high, the small screen SG06 of FIG. 20 (A) or the small screen SG07 of FIG. 21 (A) is displayed, and if the authority of the clerk on the receiving side is not high, the authority of the clerk on the receiving side is not high. You may not give any options (for example, you may process the registration information from other terminals according to the preset contents).

Further, in the above embodiment, how the normal mode POS terminal 20-2, which is the destination of the registration information, processes the registration information (payment only, registration) on the own terminal (POS terminal 20-2). The case of giving the option to the clerk on the receiving side has also been described (see FIGS. 22 (A), 22 (B), etc.), but whether or not to give the option to the clerk on the receiving side is determined by the clerk on the receiving side. It may be different depending on the authority. For example, if the authority of the clerk on the receiving side is high, the small screen SG08 of FIG. 22 (A) or the small screen SG09 of FIG. 22 (B) is displayed, and if the authority of the clerk on the receiving side is not high, the authority of the clerk on the receiving side is not high. You may not give any choices (for example, you may process the registration information from other terminals according to the preset contents).

Further, in the above embodiment, the clerk (sending side or receiving side clerk) can select how to process (payment only, registration) the registration information on the POS terminal 20-2 on the receiving side of the registration information. However (see FIGS. 18 (B), 22 (A), 22 (B), etc.), how is the registration information processed at the POS terminal 20-2 on the receiving side of the registration information (payment only, registration). It may be different depending on the installation position of the POS terminal 20-2. In other words, whether or not to take over (whether or not to entrust) the registration process to another terminal to which the registration information is sent is replaced by or in addition to the authority of the clerk (the clerk on the sending side or the receiving side). It may be decided based on the arrangement of (the positional relationship between the other terminal and the product, etc.).

For example, for products such as cigarettes, hot snacks, and oden, it is convenient to perform the registration process at the nearest terminal, which makes it easy to check the existence and remaining number and provide them. In addition, there may be only one store stamp to be stamped in the designated place in the storage agency business such as utility bills and home delivery business, but when the store stamp is stamped, the registration process is performed at the terminal closest to the store stamp. It is convenient. Therefore, whether or not the registration process is taken over by the other terminal to which the registration information is transmitted may be determined depending on whether or not the other terminal is close to the predetermined location of the product or store stamp as described above. .. For example, when the installation location of the POS terminal 20-2 is close to the predetermined location of the product or store mark as described above, the POS terminal 20-2 on the receiving side receives the signal from another terminal (POS terminal 20-1). Displays options (see FIGS. 18 (B), 22 (A), 22 (B), etc.) to execute the registration process based on (take over) the registration information, and the installation location of the POS terminal 20-2. If is not close to the above-mentioned product or the predetermined place of the store mark, the above-mentioned options may not be displayed. For each POS terminal 20, whether or not the installation location is close to the predetermined location of the product or store stamp as described above (or, the option of executing the registration process based on the registration information received from other terminals is selected. Whether or not to display) should be set in advance.

In addition, if a beginner clerk is required to perform work that has not yet been educated (storage agency, courier service, in-store cooking, etc.), efficiency may deteriorate. Therefore, the attributes (experience level, skill level) of the clerk concerned , The judgment may be made based on the place related to the business (storage agency, seal used for courier service, cooking place).

Further, in the above embodiment, as a message based on the instruction information transmitted by another clerk (clerk of the POS terminal 20-2) together with the registration information, "Registration from the cash register 20-1" on the small screen SG06 of FIG. 20 (A). "Do you want to process information (payment only)?" And "Do you want to process registration information (also registration) from cash register 20-1?" On the small screen SG07 in Fig. 21 (B), but the message The content is not limited to this. In addition, a plurality of types of messages are prepared, and the clerk on the sending side may select which message to display.

Further, in the above embodiment, a response button (“not button BT26”, “yes button BT27”) is provided on the small screen SG06 of FIG. 20A and the small screen SG07 of FIG. Although it is arranged, only the message may be displayed without arranging the response button (a confirmation button (OK button, etc.) that simply erases the small screen may be arranged). Further, the clerk on the transmitting side may be able to select whether or not to arrange the response button.

In the above embodiment, an example in which special information (flag) added to the registration information or special information (flag) transmitted together with the registration information is used as the instruction information has been described, but the special information ( It may be possible to control whether the designated terminal is started from the settlement process or the registration process without using a flag or the like). For example, when the designated terminal side receives the registration information including the total amount, it may start from the settlement process, and when it receives the registration information not including the total amount, it may start from the registration process. That is, in the POS terminal 20-1, when the "button BT20 that performs only the settlement process" of the small screen SG03 of FIG. 17 (B) is operated, or the "button BT23" of the small screen SG04 of FIG. 18 (A) is operated. When the operation is performed or when the "(payment only) button BT24" on the small screen SG05 of FIG. 18B is operated, the registration information including the total amount may be transmitted to the designated terminal. Further, in the POS terminal 20-1, when the "button BT21 that also performs the registration process" of the small screen SG03 of FIG. 17 (B) is operated, or the small screen SG05 of FIG. 18 (B) "does (registers)". When the "button BT25" is operated, registration information that does not include the total amount may be transmitted to the designated terminal.

Further, in the above embodiment, in order to reduce the amount of data to be sent and received, a message displayed on the receiving terminal (message such as "Do you want to process the registration information (payment only) from the cash register 20-1?"). Although it does not send or receive itself, the message itself displayed on the receiving terminal may be sent or received.

Further, in the above embodiment, the POS terminal 20-1 in the normal mode has a small screen (small screen) after pressing the send button (20-2 cash register button BT12) for the registration information with the POS terminal 20-2 in the normal mode as the destination. SG04, small screen SG05) is displayed, and transmission of registration information to the destination (POS terminal 20-2) is prohibited (temporarily prohibited), but the mode of prohibiting transmission is not limited to this. For example, it may be prohibited (completely prohibited) by hiding the send button (20-2 cash register button BT12). Further, the send button may be displayed but not reacted even if it is operated, or it may be reacted by operating the send button but an error may occur.

Further, in the above embodiment, the POS terminal 20-1 that transmits the registration information has different processing depending on the operation mode (normal mode, full self mode) of the POS terminal 20 on the receiving side (FIG. 30). (See step S800 and the like), as described above, the normal mode is basically used by the clerk. In other words, the POS terminal 20-1 has different processes depending on the usage status (usage status inferred from the operation mode) of the POS terminal 20 on the receiving side.

Further, in the above embodiment, the processing is different depending on the operation mode of the POS terminal 20 on the receiving side (see step S800 in FIG. 30 and the like), but for example, instead of the operation mode of the POS terminal 20 on the receiving side. , The processing may be different depending on the usage status (actual usage status) of the clerk of the POS terminal 20 on the receiving side. As an example, in the case of the following (a), the process proceeds to step S801 of FIG. 30 (the same process as in the case of the full self mode), and in the case of the following (b), step S802 of FIG. 30 (in the normal mode). You may proceed to the same process as in a certain case).
(A) When the receiving side POS terminal 20 (regardless of the operation mode) is not used by the clerk (b) When the receiving side POS terminal 20 (regardless of the operation mode) is used by the clerk

Further, for example, in addition to the operation mode of the POS terminal 20 on the receiving side, the processing may be different depending on the usage status (actual usage status) of the clerk of the POS terminal 20 on the receiving side. As an example, in the case of the following (A), (B), and (C), the process may proceed to step S801 of FIG. 30, and in the case of the following (D), the process may proceed to step S802 of FIG. Alternatively, in the case of the following (A), the process may proceed to step S801 of FIG. 30, and in the case of the following (B) (C) (D), the process may proceed to step S802 of FIG.
(A) When the POS terminal 20 (full self mode) on the receiving side is not used by the clerk (B) When the POS terminal 20 (normal mode) on the receiving side is not used by the clerk (C) POS on the receiving side When terminal 20 (full self mode) is used by a clerk (D) When POS terminal 20 (normal mode) on the receiving side is used by a clerk

Whether or not the POS terminal 20 on the receiving side is used by a clerk may be determined by a sensor or the like that detects the presence of a person in the vicinity of the terminal. For example, if a person is not detected continuously for a predetermined time (about 10 seconds), it may be determined that the person is not used by the clerk. The sensor may be installed on each POS terminal 20, or may be installed on a ceiling, a wall, or the like.

Further, instead of or in addition to the method using the above sensor, whether or not the POS terminal 20 on the receiving side is used by the clerk is determined (estimated) by the leaving time (non-operating time) since the last operation. You may. If the leaving time is short (for example, if it is less than a predetermined threshold (reference time)), it is determined that the product is used by a clerk, and if it is long (for example, if it is equal to or more than a predetermined threshold). You may judge that it is not used by the clerk. The above threshold value may be different for each store, each day of the week, each time zone, and each installation position (each terminal).

Further, in the above embodiment, the POS terminal 20-1 has buttons (20-2 cash register buttons BT12, 20-3) used when making a payment at another terminal when cash is inserted (detection of payment). The cashier button BT13 and the checkout button BT15) are hidden (see Fig. 11 (A), etc.), and when the checkout reservation button on another terminal is operated, the subtotal button BT10 used for checkout on the own terminal is used. It is hidden (see FIG. 24 (B, etc.)). That is, processing by the button is prohibited by erasing the unnecessary button. However, the mode of prohibiting the processing is not limited to the method of erasing the button. For example, the button may be displayed (displayed in a manner that can be understood as prohibited) but not reacted even if it is operated, or it may be reacted by operating the button but an error may occur.

In addition, when the input amount (deposit amount) is greater than or equal to the purchase amount, not when cash is input, the button used for payment on other terminals may be hidden, or the button operation may be unresponsive. You may make an error.

In the case of hiding the button when the input amount is more than the purchase amount, the display in the display field HR01 of the registration screen shows whether the input amount is less than the purchase amount or more than the purchase amount. It may be displayed. For example, the characters "greater than or equal to" or "less than" may be displayed, or a mark indicating that the purchase price is equal to or greater than the purchase price may be displayed. Further, the character color, character size, character thickness and typeface, background (display column) color, etc. of the amount of money may be different depending on whether it is less than the purchase amount or more than the purchase amount. Even in the case of hiding the button when cash is inserted, the button is displayed in a manner that indicates whether the input amount is less than the purchase amount or more than the purchase amount. May be good.

If the input amount was once more than the purchase amount, but the purchase amount increased due to later product registration and the input amount was less than the purchase amount, the input amount was more than the purchase amount in the past. However, since it is less than the purchase price at the moment, the button is not hidden as described above. If the input amount was more than the purchase amount in the past but less than the purchase amount at the present time (that is, if the input amount is more than the purchase amount even once), the button may be hidden or the like. ..

In addition, regarding the display in the display field HR01 on the registration screen, the payment type is selected in the display field HR01 regardless of whether or not the display is performed in a manner that indicates whether the input amount is less than the purchase amount or more than the purchase amount ( Information indicating whether or not the payment has been made, information that can identify the selected payment type, or read information (for example, information that can identify the type of credit card or electronic money) may be displayed. .. For example, characters, symbols, or pictures (illustrations) corresponding to the selected (or read) credit card or electronic money may be displayed.

In addition, instead of or in addition to the display field HR01, information indicating whether the input amount is less than the purchase amount or more than the purchase amount and whether or not the payment type is selected are shown at other positions on the screen. Information, information that can identify the selected payment type, information that can identify the read information, and the like may be displayed. As an example, the entire area (sheet, tab) "1" provided with the display field HR01 may be displayed. For example, the deposit status (information on whether the input amount is less than the purchase amount or more than the purchase amount) is displayed by the background color of the entire area "1", and the position is different from the display field HR01 on the area "1". A picture corresponding to the selected credit card or the like may be displayed on the screen.

As mentioned above, when cash is inserted, transaction information is mistakenly transmitted in order to hide the button used for payment on other terminals (for example). Even if the transmission is made because cash has not been inserted or the payment type has not been selected, the transmission may be canceled. For example, until the next transaction (product registration, payment, payment type selection of the next customer) is started, the transmission cancel button (not shown) is displayed, and when the transmission cancel button is operated, the transmitted transaction information is displayed. May return to the source. As a result, the customer will be able to insert cash and select the payment type, and the clerk will be able to modify the contents of the registered product. Note that returning to the sender means returning to the original situation (the situation before the transaction information was erroneously transmitted) by operating the transmission cancel button, and the transaction information is actually transmitted and received after the operation of the transmission cancel button. It is not limited to the case. For example, in the mode in which the transmission side retains the registration information even after transmission, the registration side handles the registration information held after the operation of the transmission cancel button as the information before transmission, and the reception side discards the registration information. (It can be ignored so that it will not be used hereafter).

Further, in the above embodiment, it has been explained that when the POS terminal 20-1 does not make a payment at its own terminal (such as when the payment reservation button of another terminal is operated), the cash can not be inserted into the change machine 209. However, specifically, for example, the cash (banknote, effect) slot may be closed (it may not be opened), or the cash inserted in the slot may be discharged as it is. Further, if the settlement is not performed on the own terminal, the input operation of the payment type does not work (see step S170 in FIG. 25, step S270 in FIG. 26, etc.), but specifically, it corresponds to each payment type. The small screen SG01 on which each button is arranged may be hidden, or each of the above buttons may be displayed (displayed in a manner that can be understood as prohibited, etc.) but may not be reacted even if operated, or each of the above buttons may be displayed. It may be made to react by the operation, but an error may occur.

The payment types of the above embodiment are cash, credit card, and electronic money (see FIG. 15 and the like), but other payment types (for example, gift certificates, coupons, complimentary tickets, various prepaid cards, etc.). Debit payment, etc.) may be used. In addition, when the POS terminal 20 is paid as a part of the total purchase price (for example, when there is a payment for the shortage of the face value of the gift certificate etc.), or when there is no payment but change is generated. In such a case (such as when a gift certificate or the like for which change is paid for the purchase of a product having a par value is used), it may be determined that the settlement process is executed on the terminal (the terminal for which payment has been made).

Further, in the above embodiment, when each POS terminal 20 shifts to the operation mode in the own terminal, the operation mode after the shift is notified to the other terminal, so that the POS terminal 20-1 is the latest other terminal. I always know the operation mode. Therefore, when transmitting the registration information to the other terminal, the POS terminal 20-1 refers to the operation mode of the other terminal already known by the own terminal (that is, without making an inquiry via the LAN 11) and transmits the registration information. You can check the operation mode of the other terminal that is the destination (destination). When transmitting the registration information to another terminal, the POS terminal 20-1 may inquire about the operation mode of the other terminal to be the transmission destination again via the LAN 11.

In the case of a mode in which the processing is different depending on the usage status of the clerk of the destination POS terminal (the receiving side POS terminal 20), each POS terminal 20 changes when the usage status of the clerk at the own terminal changes. By notifying the other terminal of the later usage status, the POS terminal 20-1 refers to the usage status of the clerk at the other terminal that the own terminal already knows when transmitting the registration information to the other terminal. You may check the usage status of the clerk at another terminal that is the destination (destination). When transmitting the registration information to another terminal, the POS terminal 20-1 may inquire about the usage status of the clerk at the other terminal as the transmission destination.

That is, the POS terminal 20-1 that transmits the registration data confirms the operation mode of another terminal that the own terminal already knows based on the operation for transmitting the registration data, or LAN11. The operation mode of the other terminal as the transmission destination is determined by inquiring the operation mode of the other terminal as the transmission destination via the device. The same applies to the usage status of clerk on other terminals.

Further, in the above embodiment, the POS terminal 20-1 displays the small screen SG02 by superimposing it on the registration screen when the subtotal key is operated (FIG. 13 (A)), but the POS terminal 20- Reference numeral 1 denotes a subplanning surface for displaying information or the like displayed on the small screen SG02 instead of (switching) the registration screen when the subtotal key is operated.

Further, in the above embodiment, the POS terminal 20 includes one printing unit 213 that can rotatably change the direction from the clerk side to the customer side and from the customer side to the clerk side (see FIGS. 2 to 4). Instead of one printing unit 213, two printing units (a printing unit fixedly directed to the clerk side and a printing unit fixedly directed to the customer side) may be provided.

In the above embodiment, when the registration information is transmitted to another terminal, the clerk specifies (selects) the terminal of the destination (destination) of the registration information, but when the registration information is transmitted to the other terminal, the clerk May only specify that the registration information is to be transmitted without specifying the destination terminal. That is, only the send button may be arranged. In the mode in which the clerk only specifies that the registration information is to be transmitted without specifying the destination terminal, the transmitting terminal selects one terminal as the destination according to a predetermined priority and registers it in the selected terminal. Send information. In the mode in which the destination terminal is selected according to the priority, the registration information is transmitted to the terminal selected according to the priority before the registration information is transmitted to the terminal selected according to the priority, or when the registration information is transmitted to the terminal selected according to the priority. After transmitting the registration information to the terminals selected according to the priority, the store clerk is notified which terminal has been selected (which terminal is the destination of the registration information).

Regarding the above-mentioned predetermined priority, for example, when the registration information is transmitted from the POS terminal 20-1 to another terminal (POS terminal 20-2, POS terminal 20-3), the POS terminal 20-3 in the full self mode is usually better. It may be higher than the mode POS terminal 20-2 (registration information may be preferentially transmitted to the full self mode POS terminal 20-3). When the registration information is transmitted to the POS terminal 20-2 in the normal mode having a low priority, the same process as when the clerk is using the POS terminal 20-2 (process in step 802 or less in FIG. 30). May be executed.

Further, as described above, the predetermined priority may be according to the usage status of the clerk of the POS terminal 20 on the receiving side in addition to the operation mode.

Further, in the mode in which the clerk does not specify the destination terminal (that is, the mode in which the destination terminal is selected according to the priority), the display may be different from the mode in which the clerk specifies the destination terminal. For example, when the clerk specifies the POS terminal 20-3, "Registration 20-3 is in full self mode" is displayed (see (B) in FIG. 17), but the POS terminal 20-in order of priority. When 3 is selected, the message "The destination is cashier 20-3 (full self mode)" may be displayed. In other words, the clerk may be notified which terminal is selected according to the priority.
