Description

  The present invention relates to a sales data processing apparatus and a program.

  A registration device (sales processing device) that can transmit registration information to a settlement device that is another device has been proposed (see, for example, Patent Document 1).

JP 2017-102856 A

  However, there is a possibility that a process unsuitable for the situation may be erroneously executed.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a technique capable of preventing execution of processing not suited to the situation.

  In order to solve the above-described problem, a sales data processing apparatus according to an aspect of the present invention performs a settlement process using a registration unit that executes registration processing for registering a product, and registration data generated by the registration unit. Adjusting means for executing, transmitting means for executing transmission processing for transmitting the registration data so as to be settled by another device, and prohibiting means for prohibiting execution of the adjusting processing, wherein the prohibiting means includes the transmission processing When executed, the execution of the settlement process is prohibited before the transmission process is executed.

  According to the above configuration, it is possible to suitably prevent a process unsuitable for the situation from being erroneously executed. Specifically, in the situation where the transmission process is executed, the self-adjustment is not performed in the own apparatus, so that the adjustment process not suitable for the situation is prohibited. Therefore, the settlement process that is not suitable for the situation in which the transmission process is executed is not erroneously executed.

  In order to solve the above-described problem, a sales data processing apparatus according to another aspect of the present invention includes a registration unit that executes a registration process for registering a product, and a checkout process using the registration data generated by the registration unit. A payment means for executing the transmission process, a transmission means for executing the transmission process for transmitting the registration data so that the payment can be made by another apparatus, and a prohibition means for prohibiting the execution of the transmission process. Is executed, the execution of the transmission process is prohibited before the settlement process is executed.

  According to the above configuration, it is possible to suitably prevent a process unsuitable for the situation from being erroneously executed. Specifically, in a situation where a settlement process is executed, registration data is not transmitted to other devices, and therefore a transmission process that is not suitable for the situation is prohibited. Therefore, a transmission process that is not suitable for the situation where the settlement process is executed is not erroneously executed.

  In order to solve the above-described problem, a sales data processing apparatus according to another aspect of the present invention uses a registration unit that executes a registration process for registering a product, and a settlement using the registration data generated by the registration unit. A settlement means for executing the process, a transmission means for executing the transmission process for transmitting the registration data so as to be settled by another device, and a process for determining whether the settlement process is executed before the settlement process is executed. 1 judging means, a second judging means for judging whether or not the transmission process is executed before execution of the transmission process, and a prohibition for prohibiting execution of one of the settlement process and the transmission process And the prohibiting unit prohibits the execution of the transmission process before the execution of the settlement process when the first determination unit determines that the settlement process is to be performed before the settlement process is performed. And said If it is determined that the transmission process is performed before execution of the transmission processing by the determination means, and inhibits the execution of the settlement process before execution of the transmission process.

  According to the above configuration, it is possible to suitably prevent a process unsuitable for the situation from being erroneously executed. For example, in the situation where the transmission process is executed, the settlement in the own device is not performed, and the settlement process that is not suitable for the situation is prohibited. Therefore, the settlement process that is not suitable for the situation in which the transmission process is executed is not erroneously executed. In addition, for example, in a situation where a settlement process is executed, registration data is not transmitted to other devices, and therefore a transmission process that is not suitable for the situation is prohibited. Therefore, a transmission process that is not suitable for the situation where the settlement process is executed is not erroneously executed.

  In the above sales data processing device, whether the first determination unit is configured to execute the settlement process based on whether or not payment has been made to a change bill machine or whether or not a settlement type to be applied to the settlement process is selected. It may be determined whether or not.

  According to the above configuration, it is possible to suitably determine the situation in which the settlement process is executed.

  In order to solve the above-described problem, a program according to an aspect of the present invention is a program that causes a computer to function as a sales data processing device, and the computer performs registration processing for registering a product, A settlement unit that executes a settlement process using registration data generated by the registration unit, a transmission unit that performs a transmission process that transmits the registration data so that settlement can be performed by another device, and one of the settlement process and the transmission process The prohibition unit prohibits execution of the transmission process before execution of the settlement process when the settlement process is executed, and the transmission process is executed. In this case, the execution of the settlement process is prohibited before the transmission process is executed.

  As described above, it is possible to prevent a process unsuitable for the situation from being executed.

The customer side scanner unit 206 is a customer scanner unit, and optically reads, for example, a barcode (product code or the like) attached to a product. The customer-side scanner unit 206 may optically read a code (bar code, two-dimensional code, etc.) printed on a bill (registered trademark).

  The customer-side scanner unit 206 is used when a customer registers a product, but the customer may register the product by another method. For example, when a preset key corresponding to a product (a button for ordering a product) is displayed on the customer display unit 205, the customer may operate (press) the preset key to register the product.

  The card settlement unit 208 is a settlement mechanism using various cards (credit cards, prepaid cards such as transportation cards). The card settlement unit 208 of the present embodiment includes a card recognition unit (reading unit), a display unit, and an operation unit, but may be any unit that includes at least a card recognition unit. Note that the card recognition unit may recognize various cards (for example, a membership card, a point card, etc.) that are not directly used for payment (settlement).

  The change machine 209 (cash settlement unit) is a cash settlement mechanism, and has a bill and coin slot and a bill and coin outlet, calculates the amount of money to be inserted into the slot, The change amount which is the difference is calculated, and the change is discharged from the discharge port. The change machine 209 is directed to the customer side and is operated by the customer. When a bill or coin is inserted into the insertion slot, it is detected by a sensor (detection of insertion, detection of the number of denominations, etc.).

The clerk side display unit 210 is a touch display for the clerk, displays various information to the clerk, and accepts various inputs from the clerk.
The key operation unit 211 includes various keys (buttons) and receives various inputs from the store clerk.
The clerk side scanner unit 212 is a clerk scanner unit, and optically reads, for example, a bar code (product code or the like) attached to a product or a clerk code attached to a name tag of the clerk.

  The store clerk side scanner unit 212 is used when the store clerk registers the product, but the store clerk may register the product by other methods. For example, when a key corresponding to a product (for example, a key corresponding to a sports newspaper) is arranged in the key operation unit 211, the store clerk operates (presses) the key to register the product. Good. Moreover, when the preset key corresponding to the product is displayed on the store clerk side display unit 210, the store clerk may operate the preset key to register the product.

  The printing unit 213 prints and issues various media (receipts, bills, etc.). The printing unit 213 is configured to freely change the direction (direction of the medium issue port) from the clerk side to the customer side and from the customer side to the clerk side. The orientation of the printing unit 213 may be changed manually, or may be automatically changed (mechanically controlled, etc.) automatically in response to a transition (switching) of an operation mode (details will be described later). The correctness of the orientation of the printing unit 213 may be detected by a sensor or the like.

The audio output unit 214 outputs audio. For example, the voice output unit 214 outputs voice guidance and the like.
The communication unit 215 transmits and receives information to and from other terminals (other POS terminals 20 and the store controller 10).

(Overview of each operation mode)
Next, the operation mode of the POS terminal 20 will be described. The POS terminal 20 has a plurality of operation modes. 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 checkout processing), and is a summation mode for summarizing and inquiring sales and stocks. It does not include a maintenance mode for maintenance work, a training mode for newcomer training, and the like.

  In the following description, the POS terminal 20 executes a registration process as a mode different from the above-described operation mode classification (normal mode, full self mode, semi-self mode), and executes a checkout process. This mode 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 for explaining the outline of the normal mode. FIG. 5A is a schematic diagram showing the flow of processing (registration processing, checkout processing) in normal mode and the operation of a person (clerk, customer). FIG. 5B is the operation of the POS terminal 20 in normal mode. It is the flowchart which showed the basic flow. FIG. 6 is a diagram for explaining the outline of the full self mode. FIG. 6A is a schematic diagram showing the flow of processing (registration processing, checkout processing) and the operation of a person (customer) in the full self mode, and FIG. 6B is the operation of the POS terminal 20 in the full self mode. It is the flowchart which showed the basic flow.

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

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

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

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

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

  Further, the 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 selection of a payment method during the registration process (details will be described later).

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

  Further, the POS terminal 20 controls change of the change / pickout by the change machine 209 in order to prevent forgetting to take change when there is change, and a sensor or the like indicates that the customer has removed the change / pipe. The receipt of the receipt by the printing unit 213 may be controlled. The same applies to other operation modes.

  Further, in the normal mode, as described above, the registration process is executed on the clerk side, and the settlement process is executed on the customer side of the terminal using the registration information generated in the registration process (see FIG. 5). In addition, the registration process is performed on the store clerk side, and the registration information generated in the registration process is transmitted to another terminal (another terminal capable of executing the settlement process, for example, another POS terminal 20) (via the LAN 11). , Send directly to other terminals, or send to other terminals via the store controller 10 or a monitoring terminal (not shown), the same applies hereinafter), and the registration information generated in the registration process (code Code, two-dimensional code, etc.), printed on a medium, and issued as a bill can be executed. That is, the POS terminal 20 in the normal mode has a function of registering a product in the own terminal and registering the product in another terminal in addition to a function of registering the product in the own terminal and paying out in the own terminal.

  The above-described function of registering a product in its own terminal and making a checkout in another terminal is an original function of the semi-self mode. The semi-self mode is classified into a registration-only mode and an accounting-only mode. The POS terminal 20 in the semi-self mode (registration-only mode) has a function of registering a product at its own terminal and making payment at another terminal. Specifically, the POS terminal 20 in the semi-self mode (registration-only mode) executes registration processing on the store clerk side, and transmits the registration information generated in the registration processing to another terminal (or generated in the registration processing). Enrolled registration information is encoded and printed on a medium and issued as an accounting ticket). The POS terminal 20 in the semi-self mode (accounting-only mode) has a function of paying out products registered in other terminals. Specifically, the semi-self mode (accounting-only mode) POS terminal 20 receives the registration information transmitted from the semi-self mode (registration-only mode) POS terminal 20 (or semi-self mode (registration-only mode) POS). The bill issued at the terminal 20 is read), and the settlement process is executed.

  Note that the POS terminal 20 in the normal mode has a function of registering products with the own terminal and paying out with other terminals, like the POS terminal 20 in the semi-self mode (registration-only mode), but the POS terminal 20 in the full self mode. (The same applies to the POS terminal 20 in the normal mode), like the POS terminal 20 in the semi-self mode (accounting-only mode), may have a function of paying out products registered in other terminals. That is, the POS terminal 20 in the full self mode and the POS terminal 20 in the normal mode receive the registration information from other terminals (such as the POS terminal 20 in the semi-self mode (registration only mode), the normal mode POS terminal 20, etc.). The bills may be read) and the checkout process may be executed.

(Full self mode)
As shown in FIG. 6A, the full self mode is an operation mode in which registration processing is executed on the customer side and settlement processing is executed on the customer side. That is, as shown in FIG. 6B, the POS terminal 20 in the full self mode is in the registration mode or the accounting mode on the customer side. That is, the POS terminal 20 in the full self mode operates in the registration accounting mode when viewed through 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). In other words, the POS terminal 20 executes a purchase product registration process by a customer operation (scanning by the customer scanner unit 206, touching the customer display unit 205) (upper part of FIG. 6A).

  When the registration process is completed, the customer confirms the total price of the purchased product on the customer side display unit 205, inserts cash into the change machine 209, or operates the card settlement unit 208 (see FIG. 6A). ) Bottom). In other words, the POS terminal 20 executes the settlement process by the customer's operation or the like (insertion of cash into the change machine 209, operation of the card settlement unit 208) (lower part of FIG. 6A).

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

  In the full self mode, as described above, the registration process and the settlement process are executed on the customer side, but the store clerk cannot do anything. That is, even when the POS terminal 20 is operating in the full self mode, for example, the store clerk side scanner unit 212 scans the store clerk code, displays various types of information, and registers products. It is possible. In addition, the state (operation mode) in which the registration process is executed on both the clerk side and the customer side may be referred to as a double scan mode.

(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 store 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 store clerk side display unit 210, and displays the current operation mode of the own terminal in the operation mode display field on the screen. May be. 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 store 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 the image that does not correspond to the current operation mode (for example, a display mode that stands out from 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 terminal is the normal mode, the normal mode image is displayed in a display mode that stands out from the full self mode image. When the current operation mode 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. Each POS terminal 20 may display the current operation mode of its own terminal on the customer side display unit 205 as well.

  Further, each POS terminal 20 may notify the current operation mode of another terminal instead 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 the current operation mode of the other terminal. An example of a method in which each POS terminal 20 recognizes the current operation mode of each other terminal is as follows. Each POS terminal 20 notifies the other terminal of the operation mode (the latest operation mode) after the transition to the operation mode (the LAN 11 is connected). Via the 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 in the current operation mode of the other terminal.

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

(Operation mode transition (switching))
Next, the transition (switching) of the operation mode of the POS terminal 20 will be described. The operation mode of the POS terminal 20 is shifted according to an explicit mode switching operation (mode switching operation) by a store 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.

  In addition, since the mode switching button 211a is arranged at the corner of the key operation unit 211, it is possible to reduce an operation error when changing the mode and to easily change the operation mode. That is, when the mode switching button 211a is present at the corner of the key operation unit 211, for example, compared to the case where the mode switching button 211a is present near the center of the key operation unit 211, for example, the mode switching button 211a that is the operation target Since the number of adjacent buttons is small, it is unlikely that operation mistakes such as operating other buttons in a hurry will occur, and since the position of the mode switching button 211a that is the operation target can be instantly specified, mode transition operation without stress It can be performed.

  Further, since the mode switching button 211a is arranged at the corner of the key operation unit 211 at the upper right end (uppermost and rightmost end), the mode shift operation is performed not only when the store clerk is at the store clerk side but also at the customer side. Will be able to. In other words, the store clerk at the customer side usually cannot visually recognize each button of the key operation unit 211, but the mode switching button 211a present at the upper right end of the key operation unit 211 is extended from the customer side and searched. Since the mode switching button 211a as the operation target can be easily recognized only by (hand feeling), the store clerk at the customer side can perform the mode transition operation without moving to the store clerk side.

  In the present embodiment, the mode switching button 211a is arranged at the upper right corner of the key operation unit 211. However, if the position can be recognized only by groping (a position that can be recognized relatively easily), the mode is switched. The switching button 211a may be arranged at a position other than the upper right corner of the key operation unit 211. Further, instead of or in addition to arranging the mode switching button 211a at a position that can be recognized only by groping (for example, at the upper right corner), it can be distinguished from other buttons even from the customer side. Alternatively, a mode switching button 211a may be formed. For example, the size of the mode switching button 211a may be different from the size of other buttons so that the mode switching button 211a 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 protrude more than the other buttons). ) The touch of the entire surface (the surface touched by the hand) of the mode switching button 211a may be different from the touch of the other buttons (for example, only the surface of the mode switching button 211a is rough or rough) You may make it feel, or you may make it provide a protrusion and a hollow only in 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 the various advantages as described above, but instead of arranging the mode switching button 211a in the key operation unit 211. Alternatively, 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 is shifted according to an operation other than the explicit mode shift operation by the store clerk (for example, reading of the store clerk code). In addition, the POS terminal 20 uses predetermined conditions (such as elapsed time and predetermined time (schedule)) that do not depend on the store clerk's operation, commands, etc. with other terminals (POS terminal 20, monitoring terminal), etc. The operation mode shifts based on the information transmission / reception conditions. As described above, when the operation mode is changed in the own terminal, the changed operation mode may be notified to other terminals.

  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.

(Display example of POS terminal 20)
7 to 24 are display examples on the POS terminal 20. FIG. 7A is a display example on the customer side display unit 205 of the POS terminal 20-3 in the full self mode. Specifically, FIG. 7A shows the display content of the registration start screen before the start of the registration process.

  In FIG. 7A, a registration start button BT30 at the lower right of the screen is a button for instructing start of product registration.

  When the normal mode POS terminal 20 and the full self mode POS terminal 20 are compared as the POS terminal 20 to which the registration information is transmitted, the POS terminal 20 in the full self mode is more plentiful than the POS terminal 20 in the normal mode. Is preferable as a transmission destination of registration information. Since the POS terminal 20 in the normal mode is basically operated by a store clerk (see FIG. 5A), processing (for example, registration processing, customer service, etc.) continues to exist and is registered. Even if 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 respond immediately to customers who want to support the clerk. In contrast, the POS terminal 20 in the full self mode can process the registration information immediately if no customer is attached. Even if a customer is attached, the POS terminal 20 may simply process in order. 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 the store clerk use state, there is a possibility that the processing is delayed and inefficiency occurs. Therefore, the POS terminal 20 in the full self mode in the clerk non-use state is more suitable as the transmission destination of the registration information than the POS terminal 20 in the clerk use state in the normal mode.

  In view of the above, the store clerk is informed of whether the registration information transmission destination POS terminal 20 is preferable or which is more preferable when there are a plurality of registration information transmission destinations. As an example, in FIG. 10A, the outline of the 20-3 register button BT13 corresponding to the POS terminal 20-3 in the full self mode, which is relatively preferable as a transmission destination of registration information, is indicated by a solid line, The outline portion of the 20-2 register button BT12 corresponding to the POS terminal 20-2 in the normal mode, which is relatively unfavorable, is indicated by a broken line. Note that the notification by the above-described contour portion is an example, and whether the registration information transmission destination POS terminal 20 is preferable or which is more preferable when there are a plurality of registration information transmission destinations. 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 displayed in gray down, or a punishment mark or a diagonal line may be added to the entire button. Further, the display size, shape, and display position of the button may be varied 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 "recommendation") may be given to the button. Or a badge-like image).

  In view of the above, although details will be described later, transmission of registration information to the POS terminal 20 in the normal mode in the store clerk use state may be prohibited (for example, “No button BT22 in FIG. 18A or FIG. 18B). ”Is prohibited if there is an operation such as“). If the registration information is prohibited from being transmitted to the POS terminal 20 in the normal mode in the clerk use state, the processing can be efficiently performed as a whole without inefficiency.

  Although details will be described later, the prohibition of transmission of registration information to the POS terminal 20 in the normal mode in the store clerk use state may be canceled (for example, “Yes button BT23” in FIG. 18A or FIG. 18B). ) Is canceled when there is an operation such as “Yes (only settlement) button BT24” or “Yes (also registration) button BT24”). That is, if registration information is not inefficient even if the registration information is transmitted to the terminal in the store clerk use state, the registration information can be appropriately transmitted, so that the processing can be performed efficiently. Alternatively, if the registration information is not transmitted to the terminal in the store clerk usage state, the registration information can be transmitted as appropriate, so that the processing can be performed efficiently. The case where registration information is not inefficient even if the registration information is sent to the terminal in the store clerk use state is, for example, a case where a store clerk is attached but can be processed immediately if the registration information is sent, or actually the store clerk. This is the case when is not attached. If the registration information is not sent to the terminal in the store clerk's use state, it will be inefficient. For example, if the cash cannot be settled at the terminal due to a hardware or software failure or insufficient change, If a receipt cannot be issued at the terminal due to a hardware or software failure or out of paper, etc., a specific payment type (credit card payment, electronic money) This is the case when payment cannot be made.

  When the “No button BT22” on the small screen SG04 in FIG. 18A is operated, the POS terminal 20-1 simply deletes the small screen SG04 (returns to the state in FIG. 15A). That is, registration information is not transmitted to the designated terminal (POS terminal 20-2).

  When the “activate button BT23” on the small screen SG04 in FIG. 18A is operated, the POS terminal is operated in the same manner as when the “button BT20 that performs only the settlement process” on the small screen SG03 in FIG. 20-1 deletes the small screen SG04 and transmits registration information to the designated terminal (POS terminal 20-2) so that the designated terminal starts from the settlement process.

  FIG. 18B is a display example on the clerk side display unit 210 of the POS terminal 20-1 in the normal mode. The POS terminal 20-1 may display the small screen (small window) SG05 shown in FIG. 18B on the clerk side display unit 210 instead of the small screen SG04 shown in FIG.

  The small screen SG05 in FIG. 18B notifies the store clerk that the operation mode of the designated terminal (POS terminal 20-2) is the normal mode and that the designated terminal is being used by another store clerk. In addition, the transmission side clerk selects whether to transmit registration information to the designated terminal and whether to perform registration processing at the designated terminal. That is, if the clerk of the POS terminal 20-1 does not transmit the registration information to the designated terminal, the clerk operates the “no button BT22” and transmits the registration information to the designated terminal. In the case where only the settlement process is performed without performing the registration process based on the information, the “Yes (settlement only) button BT24” is operated, and the registration information is transmitted to the designated terminal.

(Description of flowchart in 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 no cash has been input or no payment type has been entered. . That is, at the start of the flowchart of FIG. 25, a registration screen (initial state registration screen) as shown in FIG. 9A, for example, is displayed on the clerk side display unit 210 of the POS terminal 20-1. Shall.

Step S100: The POS terminal 20-1 determines whether or not the product has been scanned (scan by the clerk side scanner unit 212, touch to the clerk side display unit 210). That is, the POS terminal 20-1 determines whether or not one item of merchandise has been registered. If the product has been scanned, 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, it progresses to step S120.
Step S120: For example, as shown in FIG. 10A, the POS terminal 20-1 includes a subtotal button BT10, a transmission button (20-2 cash register button BT12, 20-3 cash register button BT13), and a check ticket button BT15. indicate. Then, it progresses 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 a settlement type has been input. If the settlement type is input, the process proceeds to step S160. If the settlement type has not been input, 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. If the other terminal settlement reservation button 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, it progresses to step S160.

Step S160: The POS terminal 20-1 prohibits transmission or the like (transmission of registration information, issuance of bills).

(Registration screen in FIG. 24 (B))
Following the state of the display content in FIG. 10A, the POS terminal 20-1 in the normal mode operates when the other terminal settlement reservation button (not shown) is operated (step S240 (YES) in FIG. 26). As shown in FIG. 24B, the subtotal button BT10 is hidden (erased) (step S270 in FIG. 26).

  In the flowcharts of FIGS. 25 to 32, the case where the POS terminal 20 includes the other terminal settlement reservation button (not shown) has been described. However, the POS terminal 20 transmits a transmission instead of or in addition to the other terminal settlement reservation button. A reservation button (not shown) may be provided. Further, instead of or in addition to the other terminal settlement reservation button (or transmission reservation button), an accounting ticket issue reservation button (not shown) may be provided.

  When the transmission reservation button is operated, the POS terminal 20-1 prohibits the checkout process and the bill issuance at the terminal. For example, in the flowchart of FIG. 25, when the transmission reservation button is operated, the POS terminal 20-1 controls not to accept cash input and payment type input, and the subtotal button BT10 and accounting Control is performed so that the ticket button BT15 is not displayed. Further, for example, in the flowchart of FIG. 26, when the transmission reservation button is operated, the POS terminal 20-1 controls not to accept the input of cash and the input of the settlement type, and FIG. As shown in FIG. 5, the subtotal button BT10 and the bill button BT15 are hidden (erased).

And the transmission button (20-2 register button BT12, 20-3 register button BT13) are controlled not to be displayed. Also, for example, in the flowchart of FIG. 26, when the bill issuing reservation button is operated, the POS terminal 20-1 controls not to accept cash input and payment type input, and FIG. As shown to (A), subtotal button BT10, 20-2 cash register button BT12, and 20-3 cash register button BT13 "are hidden (erased).

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

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

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

  That is, the POS terminal 20-1 cancels the prohibition of transmission of registration information addressed to the POS terminal 20-2. More specifically, after notifying that the transmission of the registration information destined for the other POS terminal 20-2 in the normal mode is prohibited, an operation to transmit is performed by a store clerk on the transmission side. The transmission prohibition is cancelled.

  Further, when the POS terminal 20-1 in the normal mode transmits the registration information with the other POS terminal 20-2 in the normal mode as the destination, the POS terminal 20-2 that is the destination of the registration information is based on the registration information. The transmission side clerk (the clerk logged into the POS terminal 20-1) can select whether the registration process is performed or only the settlement process is performed based on the registration information (FIG. 18B). , See steps S845 and S855 in FIG. 30 and steps S1845 and S1855 in FIG. 31). Further, the POS terminal 20-2 that is the destination of the registration information displays a selection that can be made by the clerk on the transmission side (that is, the instruction contents for the clerk on the receiving side (the clerk logged in to the POS terminal 20-1)). (See FIGS. 20A and 21A).

  That is, when the POS terminal 20-1 transmits registration information with the other POS terminal 20-2 in the normal mode as a destination, other clerk (the clerk logged into the POS terminal 20-2) together with the registration information. Instruction information (instruction information on how to process the registration information (only settlement and registration). In this embodiment, special information (flag)) is transmitted.

(Prohibition of one of the settlement at the own terminal and the settlement at other terminals)
Further, according to the POS system 1 of the present embodiment, the POS terminal 20-1 in the normal mode, when cash is inserted into the change machine 209, the other terminals (POS terminal 20-2, POS terminal 20). -3), the buttons (20-2 cash register button BT12, 20-3 cash register button BT13, check ticket button BT15) used for settlement are not displayed (FIG. 11A, step S160 in FIG. 25). (See step S260 in FIG. 26). The same applies when the payment type is selected (see step S160 in FIG. 25, step S260 in FIG. 26, etc.).

  In other words, when the POS terminal 20-1 is to be settled at its own terminal (POS terminal 20-1), before the actual settlement (for example, during the registration process), the other terminal ( Transmission of registration information to the POS terminal 20-2 and POS terminal 20-3) is prohibited, and issuance of bills is prohibited.

  On the other hand, the POS terminal 20-1 in the normal mode issues a subtotal button BT10 to be used for settlement at the own terminal (POS terminal 20-1) and a bill when there is a declaration by the transmission reservation button. The bill voucher button BT15 used in the case is not displayed (see FIG. 23A). In addition, the POS terminal 20-1 in the normal mode includes a subtotal button BT10 used for settlement in the own terminal (POS terminal 20-1) and other terminals when there is a declaration by the bill issuing reservation button. The transmission buttons (20-2 cash register button BT12 and 20-3 cash register button BT13) used when transmitting registration information are not displayed (see FIG. 24A). Further, the POS terminal 20-1 in the normal mode does not display the subtotal button BT10 used when the settlement is performed in the own terminal (POS terminal 20-1) when there is a declaration by the other terminal settlement reservation button. (See FIG. 24B, see step S170 in FIG. 25, step S270 in FIG. 26, etc.).

  That is, when the POS terminal 20-1 is to be settled at another terminal (POS terminal 20-2, POS terminal 20-3), before the actual settlement (for example, during the registration process) ), The settlement 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 changed and modified as appropriate.

  For example, in the above embodiment, whether or not the normal mode POS terminal 20-1 transmits registration information to the POS terminal 20-2 when transmitting the registration information to the normal mode POS terminal 20-2 as a destination. The POS terminal 20-1 transmits registration information to a terminal different from the POS terminal 20-2 (specifically, the POS terminal 20-3 in the full self mode). It may be possible to make the store clerk confirm whether or not.

  For example, in addition to the “do not button BT22” and “do button BT23” in the small screen SG04 in FIG. 18A, a “button to send to another device (POS terminal 20-3)” is arranged, and “other device (POS)” is displayed. When the “transmission button to the terminal 20-3)” is operated, the small screen SG04 is erased and the checkout process is performed on the POS terminal 20-3 in the full self mode instead of the POS terminal 20-2 in the normal mode. The registration information may be transmitted so as to start from.

  Alternatively, instead of the “Yes button BT23” on the small screen SG04 in FIG. 18A, a “button to send to another device (POS terminal 20-3)” may be arranged. That is, instead of arranging the “Yes button BT23” on the small screen SG04, the “No button BT22” and the “Button to send to another device (POS terminal 20-3)” may be arranged. That is, the POS terminal 20-1 may prohibit transmission of registration information destined for the POS terminal 20-2 in the normal mode.

  Further, in addition to the “do not button BT22”, “do (only settlement) button BT24”, and “do (registration) button BT25” on the small screen SG05 of FIG. 18B, “other device (POS terminal 20-3)”. “Transmit (only settlement) button” and “Send (also register) button to other device (POS terminal 20-3)” are arranged and “Send to other device (POS terminal 20-3)” (settlement only) When the “button” is operated, the small screen SG05 is deleted, and the registration information is entered so that the POS terminal 20-3 in the full self mode, not the POS terminal 20-2 in the normal mode, is started from the settlement process. When the button “Send (also registers) to another device (POS terminal 20-3)” is operated, the small screen SG05 is erased and not the POS terminal 20-2 in the normal mode. To self-timer mode of the POS terminal 20-3 may transmit the registration information to be started from the registration process.

  Alternatively, in place of the “Yes (only checkout) button BT24” on the small screen SG05 of FIG. 18B, a “button to send (only checkout) to another device (POS terminal 20-3)” is arranged and “Yes ( Instead of the “registration” button BT25 ”, a“ button for transmitting (also registering) to another device (POS terminal 20-3) ”may be arranged.

  In the above embodiment, whether or not the normal mode POS terminal 20-1 transmits the registration information to the POS terminal 20-2 when transmitting the registration information to the normal mode POS terminal 20-2 as a destination. However, the POS terminal 20-1 may simply prohibit the transmission of registration information destined for the POS terminal 20-2 without giving the option. For example, the POS terminal 20-1 does not display the small screen SG04 in FIG. 18A or the small screen SG05 in FIG. 18B, and the small screen SG04 in FIG. 18A or the small screen SG05 in FIG. The same control as when the “no button BT22” on the screen SG05 is operated may be performed. Note that the POS terminal 20-1 may notify that the transmission of registration information destined for the POS terminal 20-2 is prohibited.

  In addition, the normal mode POS terminal 20-1 selects the registration information to be transmitted to the normal mode POS terminal 20-2 as a destination, and the registration at the destination when the registration information is transmitted to the destination. Whether or not to give an option of how to process information (only settlement and registration) may be varied depending on the authority of the store clerk on the transmission side. For example, when the authority of the store clerk on the transmission side is high, the “No button BT22”, “Yes (only checkout) button BT24”, and “Yes (registration) button BT25” are displayed on the small screen SG05 in FIG. In addition, a “transmission (only settlement) button” to the other device (POS terminal 20-3) and a “transmission (registration) button to other device (POS terminal 20-3)” are arranged and displayed on the transmission side. When the authority of the store clerk is medium, the small screen SG04 in FIG. 18A or the small screen SG05 in FIG. 18B is displayed. Alternatively, the registration information may be prohibited from being sent to the POS terminal 20-2 in the normal mode.

  In the above-described embodiment, the POS terminal 20-2 in the normal mode, which is the destination of the registration information, gives the reception clerk whether or not to process the registration information in the own terminal (POS terminal 20-2). Although the case of giving is also described (see FIG. 20A, FIG. 21A, etc.), whether or not the option is given to the reception clerk may be made different depending on the authority of the reception clerk. Good. For example, when the authority of the reception clerk is high, the small screen SG06 of FIG. 20A or the small screen SG07 of FIG. 21A is displayed, and when the authority of the reception clerk is not high, No option may be given (for example, processing may be performed in accordance with contents set in advance as to whether or not to process registration information from another terminal).

  In the above-described embodiment, how the registration information destination POS terminal 20-2 in the normal mode processes the registration information (only settlement and registration) in its own terminal (POS terminal 20-2). The case where the above-mentioned option is given to the reception side clerk has also been described (see FIG. 22A, FIG. 22B, etc.). It may be different according to authority. For example, when the authority of the reception side clerk is high, the small screen SG08 of FIG. 22A or the small screen SG09 of FIG. 22B is displayed, and when the authority of the reception side clerk is not high, No options may be given (for example, processing may be performed in accordance with contents set in advance as to how registration information from other terminals is processed).

  Further, in the above embodiment, the store clerk (transmission side or reception side store clerk) can select how the registration information is processed (only settlement and registration) in the POS terminal 20-2 on the registration information receiving side. However, (see FIG. 18B, FIG. 22A, FIG. 22B, etc.), how the registration information is processed in the POS terminal 20-2 on the registration information receiving side (only the settlement is registered) May also be made different depending on the installation position of the POS terminal 20-2. In other words, whether or not to take over the registration process in another terminal that is the transmission destination of registration information instead of or in addition to the authority of the store clerk (transmission or store clerk), etc. May be determined based on the arrangement (positional relationship between the other terminal and the product).

  For example, for products such as cigarettes, hot snacks, oden, etc., it is convenient to perform the registration process at the nearest terminal where it is easy to check the presence / absence and remaining number. In addition, only one store mark may be placed at a predetermined place in a storage agency business such as a utility bill or a home delivery service. When a store mark is stamped, registration processing is performed at a terminal nearest to the store mark. And convenient. Therefore, whether or not to take over the registration process in the other terminal that is the transmission destination of the registration information may be determined depending on whether or not the other terminal is close to a predetermined place of the product or the store mark as described above. . For example, when the installation location of the POS terminal 20-2 is close to a predetermined location of the above-mentioned product or store mark, it is received from the other terminal (POS terminal 20-1) at the POS terminal 20-2 on the receiving side. An option (see FIG. 18B, FIG. 22A, FIG. 22B, etc.) for executing the registration process based on the registration information is displayed, and the installation location of the POS terminal 20-2 However, if the item is not close to the predetermined place of the product or the store mark as described above, the above-mentioned options may not be displayed. For each POS terminal 20, whether the installation location is close to a predetermined location of the above-mentioned product or store seal (or an option for executing the registration process based on the registration information received from another terminal) It may be set in advance whether or not to display.

  In addition, since the efficiency of a beginner store clerk may be deteriorated if a task that is not yet educated (storage agent, courier service, in-store cooking, etc.) is required, the attribute (experience level, skill level) of the store clerk The determination may be made based on the location related to the business (storage agent, seal used for courier service, cooking location).

  Moreover, in the said embodiment, as a message based on the instruction information transmitted to other clerk (a clerk of the POS terminal 20-2) together with the registration information, “registration from the register 20-1” in the small screen SG06 of FIG. "Do you want to process the information (only settlement)?" Or "Do you want to process the registration information (also registration) from the cash register 20-1?" On the small screen SG07 in FIG. The content is not limited to this. Also, a plurality of types of messages may be prepared, and the sending clerk may be able to select which message is to be displayed.

  In the above embodiment, response buttons (“No button BT26” and “Yes button BT27”) are displayed on the small screen SG06 in FIG. 20A and the small screen SG07 in FIG. Although it is arranged, only a message may be displayed without arranging a response button (a confirmation button (such as an OK button) that simply deletes the small screen may be arranged). Further, it may be possible for the clerk on the transmission side to select whether or not to arrange a 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. Without using a flag or the like, it may be controlled whether the designated terminal starts from the settlement process or the registration process. For example, when registration information including the total amount is received on the designated terminal side, the adjustment process may be started, and when registration information not including the total amount is received, the registration process may be started. That is, in the POS terminal 20-1, when the “button BT20 for performing only the checkout process” on the small screen SG03 in FIG. 17B is operated, or the “ON button BT23” on the small screen SG04 in FIG. When operated or when the “Yes (only settlement) button BT24” on the small screen SG05 in FIG. 18B is operated, the registration information including the total amount may be transmitted to the designated terminal. In addition, the POS terminal 20-1 performs “when (registration is performed)” when the “button BT21 that also performs registration processing” of the small screen SG03 of FIG. 17B is operated, or when the small screen SG05 of FIG. 18B is operated. When the button BT25 "is operated, registration information that does not include the total amount may be transmitted to the designated terminal.

  In the above embodiment, in order to reduce the amount of data to be transmitted / received, a message displayed on the receiving terminal (message such as “Do you want to process registration information (only settlement) from the cash register 20-1?”). Although the message itself is not transmitted / received, the message itself displayed on the receiving terminal may be transmitted / received.

  In the above-described embodiment, the POS terminal 20-1 in the normal mode has a small screen (small screen) after pressing the transmission button (20-2 cash register button BT12) for registration information with the POS terminal 20-2 in the normal mode as a 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 transmission prohibition is not limited to this. For example, the transmission button (20-2 register button BT12) may be prohibited (completely prohibited) by hiding it. Further, the transmission button may be displayed but may not be reacted even when operated, or may be reacted by operating the transmission button but an error may be caused.

  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 receiving POS terminal 20 (FIG. 30). As described above, the normal mode is basically used by the store clerk as described above. In other words, the POS terminal 20-1 performs different processing according to the usage status (the usage status inferred from the operation mode) of the reception-side POS terminal 20.

Further, in the above embodiment, the processing is different depending on the operation mode of the reception-side POS terminal 20 (see step S800 in FIG. 30). For example, instead of the operation mode of the reception-side POS terminal 20 The processing may be varied 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 (a) below, the process proceeds to step S801 in FIG. 30 (the same process as in the full self mode), and in the case of (b) below, step S802 in FIG. 30 (in the normal mode). It is also possible to proceed to the same processing as in a certain case.
(A) When receiving POS terminal 20 (regardless of operation mode) is not used by a store clerk (b) When receiving POS terminal 20 (regardless of operation mode) is used by a store clerk

Further, for example, in addition to the operation mode of the POS terminal 20 on the receiving side, the processing may be changed according to the usage situation (actual usage situation) of the store clerk of the POS terminal 20 on the receiving side. For example, in the following cases (A), (B), and (C), the process may proceed to step S801 in FIG. 30, and in the following case (D), the process may proceed to step S802 in FIG. Alternatively, in the case of (A) below, the process may proceed to step S801 in FIG. 30, and in the following cases (B), (C), and (D), the process may proceed to step S802 in FIG.
(A) When the POS terminal 20 (full self mode) on the receiving side is not used by the store clerk (B) When the POS terminal 20 (normal mode) on the receiving side is not used by the store 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 being used by a store 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 store is not used. 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 sensor, whether or not the POS terminal 20 on the receiving side is being used by a store clerk is determined (estimated) by the leaving time (non-operation time) since the last operation. May be. When the above neglected time is short (for example, when it is less than a predetermined threshold (reference time)), it is determined that it is used by a store clerk, and when it is long (for example, when it is equal to or greater than a predetermined threshold) It may be determined that it is not used by the clerk. The threshold value may be different for each store, every day of the week, every time zone, and every installation position (each terminal).

  In the above embodiment, the POS terminal 20-1 uses the buttons (20-2 cash register buttons BT12, 20-3) that are used for settlement at another terminal when cash is inserted (detection of payment). When the cashier button BT13 and the bill voucher button BT15) are not displayed (see FIG. 11 (A), etc.) and the other terminal settlement reservation button is operated, the subtotal button BT10 used for settlement at the own terminal is displayed. It is not displayed (see FIG. 24 (B etc.)). That is, by deleting a button that is no longer necessary, processing by the button is prohibited. However, the mode of prohibiting the process is not limited to the method of deleting the button. For example, the button may be displayed (displayed in a manner that can be recognized as prohibited), but may not be reacted even if operated, or may be reacted by operating the button, but an error may occur.

  In addition, when the input amount (payment amount) is equal to or greater than the purchase amount, the button used for settlement on other terminals is not displayed, or the button operation is not reacted It may be an error.

  When the input amount is greater than or equal to the purchase amount, the button is hidden. For example, in the display in the display field HR01 on the registration screen, the input amount is less than the purchase amount or greater than the purchase amount. It may be displayed. For example, characters “more than” and “less than” may be displayed, or a mark indicating that the purchase amount is greater than or equal to the purchase amount may be displayed. Further, the character color of the money amount, the character size, the thickness of the character, the font, the color of the background (display field), etc. may be different depending on whether it is less than the purchase amount or more than the purchase amount. In addition, even in the case of a mode in which the button is not displayed when cash is inserted, similarly, it is displayed in a manner in which the input amount is less than the purchase amount or greater than the purchase amount. Also good.

  In addition, if the input amount was once more than the purchase amount, but the purchase amount has increased due to subsequent product registration and the input amount is less than the purchase amount, the input amount has been more than the purchase amount in the past. However, since it is less than the purchase amount at the moment, the button is not hidden as described above. Note that the button may not be displayed when the input amount has been more than the purchase amount in the past but is less than the purchase amount at the present time (that is, when the input amount is more than the purchase amount even once). .

  Regardless of whether or not the display in the display field HR01 of the registration screen is displayed in a manner in which the input amount is less than the purchase amount or greater than the purchase amount, the settlement type is selected in the display field HR01 ( Information indicating whether or not the information has been determined, information that can identify the selected payment type, and read information (for example, information that can identify the type of credit card or electronic money) may be displayed. . For example, characters, symbols, and pictures (illustrations) corresponding to a selected (or read) credit card or electronic money may be displayed.

  In addition to 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 the settlement type is selected are displayed 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, depending on the background color of the entire area “1”, the deposit status (information indicating whether the input amount is less than the purchase amount or more than the purchase amount) is displayed, and the position is different from the display field HR01 on the region “1”. In addition, a picture corresponding to the selected credit card or the like may be displayed.

  In addition, as described above, when there is an input of cash, etc., in order to hide the button used when the payment is made in another terminal, the transaction information is erroneously transmitted (for example, The transmission may be canceled even if it has been transmitted because no cash has been inserted or no payment type has been selected. For example, until the next transaction (next customer's product registration, payment, payment type selection) is started, a transmission cancel button (not shown) is displayed, and when the transmission cancel button is operated, the transmitted transaction information May be returned to the transmission source. As a result, the customer can insert cash, select a settlement type, and the like, and the store clerk can correct the contents of the registered product. Note that returning to the transmission source means returning to the original state (the state before sending the transaction information by mistake) 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 a mode in which registration information is retained after transmission on the transmission side, the registration side handles registration information retained after operation of the transmission cancel button as information before transmission, and the reception side discards the registration information. (It can be ignored so that it will not be used later).

  Moreover, in the said embodiment, when the POS terminal 20-1 did not perform payment in its own terminal (when another terminal payment reservation button was operated etc.), it demonstrated that the insertion of the cash to the change machine 209 became ineffective. However, specifically, for example, a cash (banknote, effect) slot may be closed (may not be opened), or the cash thrown into the slot may be discharged as it is. In addition, when payment is not performed at the terminal itself, the payment type input operation is not effective (see step S170 in FIG. 25, step S270 in FIG. 26, etc.), but specifically, it corresponds to each payment type. The small screen SG01 in which each button is arranged may be hidden, or each button may be displayed (displayed in a manner known to be prohibited, for example), but may not be reacted even when operated. The reaction may be caused by an operation, but an error may be caused.

  In addition, there are three types of payment in the above embodiment: cash, credit card, and electronic money (see FIG. 15 and the like), but other payment types (for example, gift certificates, coupon tickets, preferential tickets, various prepaid cards, Debit settlement etc.). The POS terminal 20 may receive a change when there is a payment as a partial price of the total purchase amount (for example, when there is a payment for a shortage of a face value such as a gift certificate), or there is no payment but a change occurs. In such a case (for example, when using a gift certificate or the like for which a change is paid for the purchase of a product less than the face value), it may be determined that the settlement process is executed at the terminal (the terminal where the deposit has been made).

  Further, in the above-described embodiment, each POS terminal 20 notifies the other terminal of the operation mode after the transition when the operation mode is shifted in its own terminal. Therefore, the POS terminal 20-1 is the latest other terminal. Keep track of the operating mode. Therefore, when transmitting the registration information to another terminal, the POS terminal 20-1 refers to the operation mode of the other terminal already known by the terminal itself (that is, without making an inquiry via the LAN 11). It is possible to confirm the operation mode of the other terminal that is the destination (destination). Note that the POS terminal 20-1 may inquire the operation mode of the other terminal as the transmission destination via the LAN 11 again when transmitting the registration information to the other terminal.

  In the case of a mode in which processing is changed according to the use situation of the store clerk of the transmission destination POS terminal (reception-side POS terminal 20), each POS terminal 20 changes when the use situation of the store clerk at its own terminal changes. By notifying the other terminal of the subsequent usage status, the POS terminal 20-1 refers to the usage status of the clerk at the other terminal already known by the POS terminal 20-1 when transmitting the registration information to the other terminal, You may confirm the utilization condition of the salesclerk in the other terminal used as a transmission destination (destination). When the POS terminal 20-1 transmits registration information to another terminal, the POS terminal 20-1 may inquire the usage status of the store 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 the other terminal that the terminal already knows based on the operation for transmitting the registration data, or the LAN 11 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 through The same applies to the usage status of the clerk at the other terminal.

  In the above embodiment, the POS terminal 20-1 displays the small screen SG02 superimposed on the registration screen when the subtotal key is operated (FIG. 13A), but the POS terminal 20- 1 may display a small plan surface for displaying information displayed on the small screen SG02 instead of (switching) the registration screen when the subtotal key is operated.

  Moreover, in the said embodiment, although the POS terminal 20 is equipped with the one printing part 213 which can change direction freely from a shop clerk side to a customer side and a customer side to a shop clerk side (refer FIGS. 2-4), Instead of one printing unit 213, two printing units (a printing unit fixedly directed to the store 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 store clerk designates (selects) the transmission destination (destination) terminal of the registration information. However, when the registration information is transmitted to the other terminal, the store clerk May specify that transmission is to be performed without specifying a terminal to which registration information is to be transmitted. That is, only the transmission button may be arranged. In an aspect in which the store clerk only specifies that transmission is to be performed without specifying a destination terminal for registration information, the terminal on the transmission side selects one destination terminal according to a predetermined priority order, and registers with the selected terminal. Send information. In the aspect in which the destination terminal is selected according to the priority order, before transmitting the registration information to the terminal selected according to the priority order, or when the registration information is transmitted to the terminal selected according to the priority order, or After the registration information is transmitted to the terminal selected according to the priority order, the sales clerk is informed of which terminal is selected (which terminal is the transmission destination of the registration information).

  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 normal. The POS terminal 20-2 in the mode may be higher (the registration information may be preferentially transmitted to the POS terminal 20-3 in the full self mode). In addition, when transmitting registration information to the POS terminal 20-2 in the normal mode having a low priority, the same process as when the store clerk is using the POS terminal 20-2 (the process after step 802 in FIG. 30). May be executed.

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

  Further, in a mode in which the store clerk does not designate the destination terminal (that is, a mode in which the destination terminal is selected according to the priority order), a display different from the mode in which the store clerk designates the destination terminal may be performed. For example, when the store clerk designates the POS terminal 20-3, “Register 20-3 is in full self mode” is displayed (see FIG. 17B). When 3 is selected, the message “The destination is cash register 20-3 (full self mode)” may be displayed. In other words, the store clerk may be notified of which terminal has been selected according to the priority order.
