The ice cream case stores a plurality of types of products (ice cream). These products are sold in a form in which a store clerk scrapes ice with a scraper at the request of the customer, places it in a cone or cup, and hands it over to the customer. A clerk-side product specification button 41 is provided on the clerk side of the ice cream case, and a customer-side product specification button 42 is provided on the customer side. The clerk-side product designation button 41 and the customer-side product designation button 42 are provided for each of a plurality of types of products. When the product specification button 40 is operated, a product specification button operation signal is transmitted from the product specification button 40 to the POS terminal 20.

(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 business (operation mode relating to registration processing and settlement processing), and is an aggregation mode for totalizing and inquiring sales and money, etc. It does not include a maintenance mode for performing maintenance work, a training mode for newcomer training, and the like.

  In the following description, as a different aspect from the above-described operation mode classifications (normal mode, full self mode, and semi self mode), the POS terminal 20 sets the mode in which the POS terminal 20 performs the registration process to the registration mode and executes the settlement process. The mode in which the transaction is performed may be referred to as an accounting mode. In particular, the semi-self mode includes a registration-only mode dedicated to registration processing and an accounting-only mode dedicated to settlement processing.

  5 to 7 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. 5A is a schematic diagram showing the flow of processing (registration processing, settlement processing) and the operation of a person (clerk, customer) in the normal mode, and FIG. 5B is an operation of the POS terminal 20 in the normal mode. 3 is a flowchart showing a basic flow of the first embodiment. FIG. 6 is a diagram schematically illustrating the full self mode. FIG. 6A 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. 6B is an operation of the POS terminal 20 in the full self mode. 3 is a flowchart showing a basic flow of the first embodiment. FIG. 7 is a diagram schematically illustrating the semi-self mode. 7A is a schematic diagram showing the flow of processing (registration processing, settlement processing) and the operation of a person (customer) in the semi-self mode, and FIGS. 7B and 7C are diagrams of the POS terminal 20 in the semi-self mode. 5 is a flowchart showing a basic flow of an operation.

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

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

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

  That is, in the normal mode, as shown in FIG. 5 (B), the clerk first scans the product (step S10: YES) and registers the product (step S11). After pressing a subtotal key (for example, a subtotal key displayed on the clerk side display unit 210 or a subtotal key arranged on the key operation unit 211) (step S30: YES), the customer side, for example, the change machine 209 (Step S50), and the process is completed. 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 clerk completes the registration process (until the total amount is determined), but may put 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 (the 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 the selection of the payment method during the registration process (details will be described later).

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

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

  In the normal mode, as described above, the clerk executes the registration process, and executes the settlement process on the customer side of the terminal using the registration information generated in the registration process (see FIG. 5). In addition to the above, the clerk performs a registration process, and transmits the registration information generated in the registration process to another terminal (another terminal capable of executing a settlement process; for example, another POS terminal 20) (via the LAN 11). Directly to another terminal, or to another terminal via the store controller 10 or a monitoring terminal (not shown). The same applies to the following. A code, a two-dimensional code, or the like, which is printed on a medium, and is issued as a voucher can also be executed. In other words, the POS terminal 20 in the normal mode has a function of registering a product at its own terminal and making a payment at another terminal, in addition to a function of registering a product at its own terminal and making a payment at its own terminal.

  The above-described function of registering a product in the own terminal and causing the other terminal to settle the payment is an original function of the registration-only mode in the semi-self mode described later. In the semi-self 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 causing the other terminal to settle the product. Specifically, the POS terminal 20 in the semi-self mode (registration only mode) executes a registration process on the clerk side and transmits the registration information generated in the registration process to another terminal (or generates the registration information in the registration process). Encoded registration information, etc. are coded and printed on a medium, and issued as a cash voucher). The POS terminal 20 in the semi-self mode (accounting-only mode) has a function of adjusting a product registered in another terminal. 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)). The transaction ticket 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 a product on its own terminal and making payment on another terminal, like the POS terminal 20 in the semi-self mode (registration only mode). The POS terminal 20 in the normal mode (similar to the POS terminal 20 in the semi-self mode (accounting-only mode)) may have a function of paying out the merchandise registered at another terminal, similarly to the POS terminal 20 in the semi-self mode. That is, the POS terminal 20 in the full self mode or the POS terminal 20 in the normal mode receives registration information from another terminal (such as the POS terminal 20 in the semi-self mode (registration only mode) or the POS terminal 20 in the normal mode) (or You may read the bill) and execute the settlement process.

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

  In the case of the full self mode, the customer registers his or her purchased merchandise on the customer side (the customer side scanner unit 206 and the customer side display unit 205). That is, the POS terminal 20 executes the registration processing of the purchased product by the operation of the customer (scan by the customer-side scanner unit 206, touch on the customer-side display unit 205) (the upper part of FIG. 6A).

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

  That is, in the full self mode, as shown in FIG. 6B, the customer scans the product on the customer side (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's side performs settlement by, for example, the change machine 209 (step S50). 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 registration process and the settlement process are performed on the customer side, but this does not mean that the clerk cannot do anything. In other words, 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 a product. It is possible. Note that a state (operation mode) in which the registration process is being executed on both the clerk side and the customer side may be referred to as a double scan mode.

(Semi-self mode)
The semi-self mode is an operation mode using two or more POS terminals 20, and as shown in FIG. 7A, a clerk of at least one POS terminal 20 (the first POS terminal 20-1 in the example of FIG. 7). Side performs the registration process, and the customer side of another POS terminal 20 (one of the second POS terminal 20-2 and the third POS terminal 20-3 in the example of FIG. 7) performs the settlement process. This is the operation mode to be executed. That is, in the case of the semi-self mode, at least one device (in the example of FIG. 7, one of the first POS terminals 20-1 as shown in FIG. 7B) is in the registration only mode, and at least one other device (FIG. In the example of (2), as shown in FIG. 7C, the two POS terminals 20-2 and the third POS terminal 20-3) are in the accounting-only mode.

  In the case of the semi-self mode, the clerk uses the first POS terminal 20-1 in the registration-only mode to register the customer's purchased merchandise on the clerk side (the clerk-side scanner 212, the clerk-side display 210, and the key operation unit 211). That is, the first POS terminal 20-1 executes the registration process of the purchased product by the operation of the clerk (operation of the clerk-side scanner unit 212, the clerk-side display unit 210, the key operation unit 211, and the like) (FIG. 7A). Upper row).

  When the registration process by the clerk is completed, the customer moves to the second POS terminal 20-2 in the accounting only mode, checks the total price of the purchased product on the clerk side display unit 210, and inserts money into the change machine 209, or Then, the user operates the card settlement unit 208 to settle the account (lower part in FIG. 7A). That is, the second POS terminal 20-2 executes the settlement process by a customer operation or the like (insertion of money into the change machine 209, operation of the card settlement unit 208) (the lower part of FIG. 7A).

  When the registration process is completed at the POS terminal 20 in the registration-only mode (the first POS terminal 20-1 in the example of FIG. 7), the customer moves from the POS terminal 20 in the registration-only mode to the POS terminal 20 in the accounting-only mode (FIG. 7). In the example, the POS terminal 20 (the second POS terminal 20-2) moves to the destination POS terminal 20 (the second POS terminal 20-2). Necessary information (registration information etc.) is supplied.

  Information required for the settlement process from the POS terminal 20 in the registration only mode (the first POS terminal 20-1 in the example of FIG. 7) to the POS terminal 20 in the accounting only mode (the second POS terminal 20-2 in the example of FIG. 7). As a supply method, a method for transmitting information necessary for the settlement process from the POS terminal 20 in the registration-only mode to the POS terminal 20 in the accounting-only mode (may be transmitted via the store controller 10; the same applies hereinafter) or a registration method There is a method in which the POS terminal 20 in the dedicated mode issues a medium (a medium on which a barcode or the like for acquiring information necessary for the settlement process is printed).

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

  That is, in the semi-self mode, first, the clerk of the POS terminal 20 (first POS terminal 20-1) in the registration-only mode registers a product. For example, as shown in FIG. 7B, the merchandise is registered by scanning with the clerk-side scanner unit 212 (step S10: YES) (step S11). After pressing a subtotal key (for example, a subtotal key displayed on the clerk side display unit 210 or a subtotal key arranged on the key operation unit 211) (step S30: YES), for example, the POS terminal 20 ( When the second POS terminal 20-2) is specified (step S31: YES), the registration information is transmitted to the specified POS terminal 20 (step S32), and the process is completed.

  Note that, in the example of FIG. 7B, at the end of the product registration, the subtotal key is pressed first, and then (after the subtotal key is pressed), the POS terminal 20 is designated. Sometimes, the processing procedure may be such that the POS terminal 20 is specified directly (without pressing the subtotal key). In the latter case, the subtotal key need not be displayed on the screen.

  Subsequently, as shown in FIG. 7C, the POS terminal 20 (the second POS terminal 20-2) designated by the POS terminal 20 (the second POS terminal 20-2) in the registration only mode receives the registration information. (Step S49: YES), on the customer side, settlement is performed by, for example, the change machine 209 (Step S50), and the process is completed.

  Note that, after transmitting the registration information (or after issuing the medium), the clerk can register the purchased product of the next customer (lower part in FIG. 7A). After transmitting the registration information, the clerk may be absent (lower part of FIG. 7A).

  In the example of FIG. 7, the second POS terminal 20-2 in the accounting-only mode uses the registration information of the product registered in the first POS terminal 20-1 in the registration-only mode to execute the settlement process. That is, the registration information used by the second POS terminal 20-2 in the account-only mode for the settlement process is the registration information of the product registered when the first POS terminal 20-1 operates in the registration-only mode. However, if the registration information can be transmitted to the second POS terminal 20-2 in the accounting-only mode (or if a bill (registered trademark; the same applies hereinafter) can be issued), the second POS terminal 20 in the accounting-only mode can be issued. The registration information used by -2 for the settlement process does not necessarily have to be the registration information of the product registered when the first POS terminal 20-1 operates in the registration-only mode.

  As an example, the registration information used by the second POS terminal 20-2 in the accounting-only mode for the settlement process may be registration information of a product registered when the first POS terminal 20-1 operates in the normal mode. That is, the second POS terminal 20-2 in the accounting-only mode may execute the settlement process using the registration information of the product registered when the first POS terminal 20-1 operates in the normal mode.

  When the clerk of the first POS terminal 20-1 completes the registration process (when transmitting registration information or issuing a cash voucher), the customer performs a settlement operation (change machine 209). If the input of money into the card, the operation of the card settlement unit 208) has already started, the transmission of registration information or the issuance of a bill may be prohibited, or the operation of settlement may be cancelled. .

  In the example of FIG. 7, the second POS terminal 20-2 receives the registration information (or reads the bill) and performs the settlement process when operating in the accounting-only mode. However, if the settlement process can be performed after receiving the registration information (or after reading the bill), the second POS terminal 20-2 receives the registration information (or reads the bill). The operation mode does not necessarily have to be the accounting-only mode.

  As an example, when operating in the full self mode, the second POS terminal 20-2 receives registration information from another terminal (for example, the first POS terminal 20-1) and uses the registration information received from the other terminal. Payment processing may be executed. When operating in the full self mode, the second POS terminal 20-2 reads a bill issued at another terminal (for example, the first POS terminal 20-1), and reads the bill read from the other terminal. The settlement process may be executed using the registration information obtained from the ticket.

  The second POS terminal 20-2 shifts from the full self mode to the accounting-only mode before executing the settlement process using the registration information received from the other terminal (the registration information received from the other terminal as the accounting process in the accounting-only mode). To handle). In addition, the second POS terminal 20-2 shifts from the full self mode to the accounting only mode before executing the accounting process using the bill issued at the other terminal. Process registration information based on issued vouchers).

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

(Notification of operation mode)
Each POS terminal 20 may report 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 column of its own terminal on the clerk side display unit 210, and displays a current operation mode of its own terminal in an operation mode display column 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 displays the current operation mode of the own terminal on the screen. The displayed image may be displayed in a display mode different from the image not corresponding 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. When the current operation mode is the full self mode, the full self mode image may be displayed in a display mode more conspicuous than the normal mode image. Each POS terminal 20 may also display the current operation mode of its own terminal on the customer side display unit 205 in the same manner.

  Further, each POS terminal 20 may report the current operation mode of another terminal instead of or in addition to the current operation mode of its own terminal. That is, the POS terminals 20 may notify each other of the current operation mode of the other terminal by recognizing the current operation mode of the other terminal. One example of a method in which each POS terminal 20 recognizes the current operation mode of another terminal is that each POS terminal 20 notifies another terminal of the operation mode after the transition (the latest operation mode) after the transition of the operation mode. Via the store controller 10 or a monitoring terminal (not shown). Further, each POS terminal 20 may report the current processing status of the other terminal as in the current operation mode of the other terminal.

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

(Switch operation mode (transition))
Next, the transition of the operation mode of the POS terminal 20 will be described. The operation mode of the POS terminal 20 is switched (the operation mode is switched) according to an explicit mode switching operation (also referred to as a mode switching operation) performed by a clerk. Specifically, the operation mode is switched according to the operation of the mode switching button 211a (see FIG. 3B) arranged at the uppermost and 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 operation mistakes when switching the operation mode, and to easily switch 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 when the mode switching button 211a is located near the center of the key operation unit 211, for example, the mode switching button 211a to be operated is Since the number of other adjacent buttons is small, an operation error such as operating another button in a hurry is unlikely to occur. In addition, since the position of the mode switching button 211a to be operated can be instantaneously specified, the mode switching operation can be performed without stress. It can be performed.

  Further, since the mode switching button 211a is arranged at the upper right corner (uppermost stage and rightmost end) of the key operation unit 211, the mode switching operation is performed not only when the clerk is on the clerk side but also when on the customer side. Will be able to do it. In other words, the clerk at the customer side cannot normally see each button of the key operation unit 211, but the mode switching button 211a at the upper right end of the key operation unit 211 reaches out from the customer side, The mode switching button 211a to be operated can be easily recognized only by (feeling of the hand), so that the clerk at the customer side can perform the mode switching operation without moving to the clerk side.

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

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

  Further, the POS terminal 20 can switch the operation mode without performing an explicit mode switching operation. For example, the POS terminal 20 receives time-related conditions such as an elapsed time (e.g., an elapsed time since the last operation) and a predetermined time (schedule), and receives information from other terminals (the POS terminal 20, the monitoring terminal, and the portable terminal). The operation mode is switched based on information transmission / reception conditions such as a mode switching instruction (mode switching instruction).

  Note that whether the POS terminal 20 switches the operation mode of its own terminal, regardless of whether the store clerk performs the explicit mode switching operation or not. The subsequent operation mode (latest operation mode) may be notified to another terminal.

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

(Display Example of POS Terminal 20 in Normal Mode)
8 to 11 show display examples on the POS terminal 20 in the normal mode. Specifically, FIGS. 8 to 10 are display examples on the clerk-side display unit 210 of the first POS terminal 20-1 in the normal mode. FIG. 11 shows a display example on the customer-side display unit 205 of the first POS terminal 20-1 in the normal mode.

  FIG. 8A shows the display contents on the registration screen in the initial state on the clerk-side display unit 210. In the following description, the initial state is a state in which processing is not in progress, for example, a state in which no product has been registered, and nothing has been done for payment (settlement), unless otherwise specified. In a state where no payment method has been selected, no cash has been inserted, and no gift certificates have been registered, etc., and nothing has been done about the customer yet (such as a situation where a membership card has not been read, etc.). is there.

  In FIG. 8A, a tab area T1 at the upper right of the screen is a tab corresponding to each display content (display screen). The first POS terminal 20-1 interrupts the registration process of the customer (the reason for the interruption is to return to the store for adding a purchased product, etc.), and the registration process of the next customer is possible. In other words, the first POS terminal 20-1 displays a new registration screen for the next customer while holding (storing) the display content (registration content) of the registration screen for the customer based on the operation of the clerk. In the example shown in FIG. 8A, the number of tabs is one (tab area T1), but the first POS terminal 20-1 displays a number of tabs corresponding to the number of registered screens (number of customers) in progress ( The registration screen to be activated (activated) is switched according to the operation (pressing) of the tab areas T1, T2, T3,...

  In the tab area T1, information for identifying the tab from other tabs (the number “1” in the example of FIG. 8A) is displayed. In the tab area T1, a clerk-side amount display field HR01 for displaying the amount of deposit from a customer is provided. Although not displayed in the example shown in FIG. 8A, various information (described later) other than the above is displayed in the tab area T1.

  The image GA02 at the lower left of the screen shows the state of the other terminal (second POS terminal 20-2) (specifically, the normal mode). The image GA03 at the lower left of the screen shows the state of the other terminal (third POS terminal 20-3) (specifically, the full POS mode).

  The first POS terminal 20-1 displays the registration screen of FIG. 8A on the clerk side display unit 210, and when the clerk registers canned beer, the clerk side display unit 210 displays FIG. The registration screen as shown in (2) is displayed. The first POS terminal 20-1 starts the sale of the product by registering the first product, here, the registration of the canned beer.

  In FIG. 8B, a 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 completing the product registration.

  At the lower right of the registration screen, a 20-2 register button BT12 and a 20-3 register button BT13 are displayed. In the normal mode, the customer performs a checkout process at the cashier (here, the first POS terminal 20-1), but as in the semi-self mode, another customer (for example, the second POS terminal 20-2 or the third POS terminal 20-3). The registration information can be transmitted to the customer, and the customer can perform the payment processing at another cash register. The 20-2 cashier button BT12 and the 20-3 cashier button BT13 are buttons for designating another cashier when the customer performs a settlement process at another cashier in the normal mode.

  The clerk operates the 20-2 cashier button BT12 when designating the second POS terminal 20-2 as a terminal for transmitting registration information. “(Normal)” indicated on the 20-2 cashier button BT12 indicates that the operation mode of the second POS terminal 20-2 corresponding to the 20-2 cashier button BT12 is the normal mode.

  The 20-3 cash register button BT13 is a button for designating a 20-3 cash register (third POS terminal 20-3). The clerk operates the 20-3 cashier button BT13 when specifying the third 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 third POS terminal 20-3 corresponding to the 20-3 cash register button BT13 is the full self mode.

  The check voucher button BT15 is a button for causing the print unit 213 to issue a check voucher. The clerk operates the check ticket button BT15 when the POS terminal 20 that has read the check sheet (the POS terminal 20 from which the customer has read the check sheet) executes the processing.

  When the POS terminal 20 in the normal mode and the POS terminal 20 in the full self mode 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 effective than the POS terminal 20 in the normal mode. Is preferable as the transmission destination of the 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 correspondence, etc.) continues to be performed and registration is performed. Sending information is likely to be impossible to process immediately, and even if it is vacant (even if there are no clerks or customers), basically leave it open to respond immediately to customers who want to support the clerk On the other hand, the POS terminal 20 in the full self mode can process the registration information immediately after transmitting the customer if there is no customer. Such a problem is unlikely to occur.

  In view of the above, the clerk is notified of whether or not it is preferable as the POS terminal 20 to which the registration information is to be transmitted, or which is more preferable when there are a plurality of transmission destinations of the registration information. As an example, in FIG. 8B, the outline of the 20-3 register button BT13 corresponding to the third POS terminal 20-3 in the full self mode, which is relatively preferable as the destination of the registration information, is indicated by a solid line, and the registration information is transmitted. The outline of the 20-2 register button BT12 corresponding to the relatively unfavorable second POS terminal 20-2 in the normal mode is indicated by a broken line. The above-described notification based on the outline portion is an example, and the clerk determines whether 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 displayed in gray down, or a penalty 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 changed depending on whether or not the POS terminal 20 is the destination of the registration information, or some information (such as “priority” or “recommended”) may be assigned to the button. Badge-like image).

  The first POS terminal 20-1 displays the registration screen shown in FIG. 8B on the clerk-side display section 210 and, when cash is inserted by the customer, inserts the cash into the clerk-side amount display field HR01 at the upper right of the screen. When a paid amount, for example, 500 yen is inserted, a numerical value of “500” is displayed. At the stage of FIG. 8B, since cash has not been input, a numerical value corresponding to the input amount, here, is displayed in a display column on the right side of the screen on which “deposit” is described. A numerical value of "0" is displayed. In addition, when cash is inserted, the payment is made at the own terminal (first POS terminal 20-1), not at the other terminals (second POS terminal 20-2, third POS terminal 20-3). For this reason, the buttons (20-2 cash register button BT12, 20-3 cash register button BT13, and cashier bill button BT15) used when making payment at the other terminals (the second POS terminal 20-2, the third POS terminal 20-3) are changed. It may be hidden (or erased).

  Subsequently, when the prepared food, which is a weighed product, is placed on the weighing device 30, the registration processing of the prepared food is performed. The first POS terminal 20-1 displays the weighed product registration screen shown in FIG. 9A and starts the prepared food registration process when the prepared food as the weighed product is placed on the weighing device 30. The weighing device 30 includes a clerk-side weighing device 31 and a customer-side weighing device 32. In the normal mode, since the clerk performs the registration process, usually, the prepared food is placed on the clerk-side weighing device 31. The side dish registration process is started. Also, when the prepared food is placed on the customer-side weighing device 32, the screen shown in FIG. 9A is displayed, and the prepared food registration process is started. For this reason, for example, even if the customer has the side dish separately from other products and the side dish is placed on the customer-side measuring device 32, the side dish registration process can be started.

  When the first POS terminal 20-1 starts the process for registering the prepared food, the first POS terminal 20-1 displays a measurement product registration start screen shown in FIG. 9A. The first POS terminal 20-1 displays a product display column GE01, a product weight display column GE02, a container display column GE03, a container weight display column GE04, and a total weight display column GE05 on the weighed product registration start screen. At this stage, since no product or container has been selected, the first POS terminal 20-1 displays the characters "product" in the product display column GE01 and displays the characters "container" in the container display column GE03. I do. Further, the first POS terminal 20-1 displays the number “000.0” in the product weight display field GE02 and the total weight display field GE05, and displays the number “−0.0” in the container weight display field GE04. .

  In addition, the first POS terminal 20-1 displays a first weighed product button BT21 of an image of sweet and sour pork, a second weighed product button BT22 of an image of levanilla, and a third weighed product button of an image of meat and potato on the weighed product registration start screen. BT23 and weighed product scroll button BT24 are displayed. When the weighed product scroll button BT24 is operated, the weighed product button of the image of the new weighed product is sequentially displayed. Further, the first POS terminal 20-1 displays a first container button BT26 of the image of the container A, a second container button BT27 of the container B, a third container button BT28 of the container C, and a container scroll button BT29. I do. When the container scroll button BT29 is operated, the container buttons of the image of the new container are sequentially displayed.

  Subsequently, the clerk operates any one of the first weighed product button BT21 to the third weighed product button BT23 shown in FIG. 9A or the weighed product button newly displayed after operating the weighed product scroll button BT24. And select the weighing product. The clerk operates one of the first container button BT26 to the third container button BT28 or the weighing commodity button newly displayed after operating the container scroll button 29 to select a container. Here, for example, when the product placed on the weighing device 30 is sour pork and the container is the container B, the clerk operates the first weighed product button BT21 indicating the sour pork and the second container button BT27 indicating the container B ( touch.

  In response to the operation of the clerk, the first POS terminal 20-1 displays "vinegar pork" in the product display column GE01 and "container B" in the container display column GE03, as shown in FIG. 9B. In addition, the first POS terminal 20-1 displays the weight of the sour pork weighed by the weighing device 30, in this example, "131.2" g in the product weight display field GE02 located on the right side of the product display field GE01. In addition, the first POS terminal 20-1 displays the minus weight of the container B, in this case, “−7.0” g, in the container weight display column GE04 located on the right side of the container display column GE03.

  The first POS terminal 20-1 stores in advance the weight of a selectable container, such as 5.8 g for container A, 7.0 g for container B, and 13.1 g for container C, for example. Then, the weight of the selected container is negatively displayed. Then, the first POS terminal 20-1 displays the total weight obtained by subtracting the weight of the container displayed in the container weight display column GE04 from the weight of the product displayed in the product weight display column GE02 in the total weight display column GE05. In the example shown in FIG. 9B, the first POS terminal 20-1 displays “124.2 g” as the total weight in the total weight display column GE05. Thus, the registration of the prepared food is performed.

  Thereafter, as shown in FIG. 10A, when the registration of all the commodities is completed, the clerk operates (touches) the subtotal button BT10. In FIG. 10 (A), canned beer, sweet and sour pork, and glue lunch are registered as commodities. In response to the operation of the subtotal button BT10, the first POS terminal 20-1 superimposes and displays the small screen (small window) SG02 on the registration screen as shown in FIG. The small screen SG02 is for informing the clerk of information related to settlement (total amount, device deposit amount (deposit amount)). In this case, in addition to the above-mentioned "canned beer" and "sweet and sour pork", "paste lunch" is registered as a product, the total amount of the product is 858 yen, and the amount of cash input into the change machine 209 is 0 yen ( (No cash has been inserted).

  At this time, the first POS terminal 20-1 displays the cash settlement screen shown in FIG. The first POS terminal 20-1 displays, on the cash settlement screen, a message prompting the player to insert cash into the change machine 209, "Please insert money", and also displays the total amount of goods and the change machine 209. The displayed amount is displayed. Here, an example is shown in which the amount displayed as the total price of the product is 858 yen, and the cash inserted into the change machine 209 is still 0 yen (no cash has been inserted).

  Subsequently, when the customer inserts cash into the change machine 209, the first POS terminal 20-1 displays the inserted amount in the display field of "deposit amount". For example, when 100 yen is inserted into the change machine 209, the first POS terminal 20-1 displays a numerical value of "100" in a display column of "deposit amount". Note that when the amount of cash put into the change machine 209 is less than the total amount of the merchandise, the first POS terminal 20-1 changes the numerical value in the display column of “deposit amount” shown in FIG. In this state, the cash settlement screen is displayed on the customer-side display unit 205.

  When the amount of cash put into the change machine 209 becomes equal to or more than the total amount of the goods, the first POS terminal 20-1 displays the cash settlement end screen (settlement execution screen) shown in FIG. It is displayed on the display unit 205. The first POS terminal 20-1 displays the end button BT40 on the cash settlement completion screen, and displays a message urging the player to operate the end button BT40, "Please press the end button if you like." The first POS terminal 20-1 displays the total amount of the commodity, the amount of cash put into the change machine 209, and the amount of change on the cash settlement end screen. In the example shown in FIG. 11B, the total price of the product is 858 yen, the amount of cash put into the change machine 209 is 1000 yen, and the amount of change is 142 yen.

  Thereafter, when the customer presses (operates) the end button BT40, the first POS terminal 20-1 pays out the change from the change machine 209, and prints and issues a receipt by the printing unit 213. Thus, the first POS terminal 20-1 ends the transaction of selling the product. Since the change is not paid out until the end button BT40 is pressed (operated), the customer can make adjustments so that the number of coins to be paid out as a change is reduced by, for example, adjusting the fraction of the amount. .

  Note that, after the operation of the subtotal button BT10 is performed, a screen on which the payment method can be selected may be displayed on the customer-side display unit 205. The screen on which the settlement method can be selected may be, for example, a screen displaying buttons corresponding to “cash”, “credit card”, and “electronic money”. The customer can touch one of these buttons to select a payment method. Further, the settlement method can be selected before the registration of the product is completed.

(Display example of POS terminal 20 in full self mode)
Subsequently, the display of the POS terminal 20 in the full self mode will be described with reference to FIGS. 12 and 13 show display examples on the POS terminal 20 in the full self mode.

  FIG. 12A shows a display example on the registration start screen displayed on the customer side display unit 205 of the first POS terminal 20-1 in which the operation mode is the full self mode. In FIG. 12A, a registration start button BT30 at the lower right of the screen is a button for instructing the start of product registration. The customer operates the registration start button BT30 before starting the product registration. Buttons BT35 to BT37 at the lower left of the screen are buttons for switching the display language to English, Chinese, and Korean, respectively.

  FIG. 12B is a display example on the registration screen displayed on the customer side display unit 205 of the first POS terminal 20-1 in which the operation mode is the full self mode.

When the call button BT73 is operated, the first POS terminal 20-1 calls a store clerk for a customer who purchases ice cream. The call of the clerk at this time may be the same as when the clerk call button BT55 shown in FIG. 15 or the like is operated, or may be different. Further, a message corresponding to the content of the operated button may be notified to the clerk. For example, when the clerk call button BT55 shown in FIG. 15 is operated, a message such as “I'm having trouble with the customer” is output to the clerk by voice or displayed on an image, and shown in FIG. 17B. When the call button BT73 is operated, a message such as "I am a customer who purchases ice cream." May be output to a clerk by voice or displayed on an image.

  Further, when the clerk-side product designation button 41 provided on the ice cream case is operated during the normal mode, a display for registering ice cream as a product is performed in the registration mode shown in FIG. 8B. In this way, the display on the display unit differs between when the clerk-side product specification button 41 is operated and when the customer-side product specification button 42 is operated.

  FIG. 18 is a flowchart illustrating an example of the operation of the POS terminal 20. Specifically, the flowchart of FIG. 18 illustrates an example of an operation from determination of an operation mode in the first POS terminal 20-1 to completion of product registration.

Step S201: The first POS terminal 20-1 determines whether the operation mode is the normal mode or the registration-only mode (semi-self mode). If the operation mode of the first POS terminal 20-1 is the normal mode or the registration-only mode (semi-self mode), the process proceeds to step S202. If the operation mode is not the normal mode or the registration-only mode (semi-self mode), the process proceeds to step S203.
Step S202: The first POS terminal 20-1 performs a registration process when the operation mode is the normal mode. The registration process when the operation mode is the normal mode will be further described later with reference to FIG.

Step S203: The first POS terminal 20-1 determines whether or not the operation mode is the full self mode. When the operation mode is the full self mode, the first POS terminal 20-1 proceeds to step S204, and when the operation mode is not the full self mode, the first POS terminal 20-1 proceeds to step S205.
Step S204: The first POS terminal 20-1 performs a registration process when the operation mode is the full self mode. The registration process when the operation mode is the full self mode will be further described later with reference to FIG.
Step S205: The first POS terminal 20-1 performs a weighing device reference operation mode setting process. The weighing device reference operation mode setting process will be further described later with reference to FIG.

Step S206: When the operation mode is another operation mode, for example, when the operation mode is the accounting-only mode (semi-self mode), the processing in the other operation mode is performed. For example, when the operation mode is the accounting-only mode (semi-self mode), the registration process of the product is not performed, and thus the process ends. Thus, the process illustrated in FIG. 18 ends.

Next, the registration processing when the operation mode is the normal mode in step S202 in FIG. 18 will be described with reference to FIG.
Step S301: The first POS terminal 20-1 determines whether or not the clerk has started registering a product. The first POS terminal 20-1 is, for example, whether or not the clerk holds his / her ID card over the clerk-side scanner unit 212 of the first POS terminal 20-1, or the clerk-side scanner unit in a state where the registration of the product has not been started. At 212, it is determined whether or not the registration of the product has been started based on whether or not the product has been registered. If the registration of the product has started, the first POS terminal 20-1 proceeds to step S302. If the registration of the product has not started, the first POS terminal 20-1 repeats the process of step S301.

Therefore, it is possible to perform appropriate processing according to the operation subject. Specifically, when the operating subject of the weighing device 30 is a clerk in the normal mode or the registration only mode, the weighed product registration screen shown in FIG. 9A is displayed on the clerk-side display unit 210, In the full self mode, if the operation subject of the weighing device 30 is a customer, the first message image MG11 shown in FIG. For this reason, when the operation subject operating the weighing device 30 is a clerk, a display is made on the clerk-side display unit 210 seen by the clerk, and when the operation subject operating the weighing device 30 is a customer, a customer-side display seen by the customer The display is made on the unit 205. For this reason, a display that is easy for the operating subject to operate can be provided. In the normal mode or the registration-only mode, a weighed product registration screen is displayed so that the clerk can easily operate the weighing product. In the full self mode, the first message image MG11 is displayed so that a customer unfamiliar with the registration process can easily operate the weighed product. Displayed as a description. Therefore, a display suitable for the operation subject can be performed.

  The POS terminal 20 determines the operation subject of the weighing device 30 according to the operation mode. For this reason, the operation subject of the weighing device 30 can be accurately determined. In determining the operating subject, it is not necessary to be the operating subject who actually performed the operation, and it is only necessary to be able to determine a person who can be the operating subject. For example, even when a store clerk places a product on the weighing device 30 in place of the customer in the full self mode, the original operation subject (assumed operation subject) is the customer, so the operation subject of the weighing device 30 is You may be determined to be a customer.

  In the POS terminal 20, a clerk-side weighing device 31 and a customer-side weighing device 32 are provided as the weighing devices 30. Therefore, both the clerk and the customer can easily measure the weighed product, and the weighed product can be efficiently processed. Further, it can also be used to determine the operation subject of the weighing device 30.

  In the POS terminal 20, a product name is displayed, and as a button for specifying a display product prepared by a clerk or the like, a clerk-side product specification button 41 operated by a clerk and a customer-side product specification button 42 operated by a customer Is provided. The POS terminal 20 displays a different screen on the clerk-side display unit 210 based on which of the clerk-side product specification button 41 and the customer-side product specification button 42 has transmitted the product specification button operation signal. For this reason, the registration of the displayed product can be performed smoothly.

  In the above example, the operation subject of the weighing device 30 is determined based on the operation mode, but may be determined by other means. For example, the operation subject is determined based on which of the clerk-side weighing device 31 and the customer-side weighing device 32 has a product placed thereon, and the operation subject when the product is placed on the clerk-side weighing device 31 is a clerk or a customer. The operation subject when a product is placed on the side weighing device 32 may be determined to be a customer. Alternatively, the vicinity of the POS terminal 20 may be photographed by an imaging device such as a camera, and the operation subject may be determined from the photographed image. The operating subject of the weighing device 30 can also be easily determined by these determination modes.

  Further, in the above example, the weighing device 30 is provided near all the POS terminals 20, but there may be a POS terminal 20 without the weighing device 30 nearby. In this case, for example, the weight information may be transmitted to another POS terminal 20. For example, the weighing device 30 may be provided near the first POS terminal 20-1, and the weighing device 30 may not be provided near the second POS terminal 20-2 and the third POS terminal 20-3. . In this case, for example, the weight information measured by the weighing device 30 may be transmitted to the second POS terminal 20-2 or the third POS terminal 20-3 designated by the clerk or customer.

  Further, in the above example, two clerk-side weighing devices 31 and customer-side weighing devices 32 are provided as the weighing devices 30, but one weighing device may be used. In this case, the operation subject of the weighing device may be based on, for example, the operation mode of the POS terminal 20, or may be provided with a sensor for detecting a customer or a clerk, and based on the detection result of this sensor.

  In the above example, the weighing device 30 is not provided with a display device, but may be provided with a display device. In addition, as the weighing device, a display device may be provided only on the clerk side, only on the customer side, or on both the clerk side and the customer side, or switch the direction so that both the clerk side and the customer side are oriented. May be provided. The display device provided in the weighing device may display the same content as one or both of the customer-side display unit 205 and the clerk-side display unit 210 in the POS terminal 20, or a different display may be displayed. May be. Alternatively, a display in which a part has the same content may be performed. In addition, when the usage mode of the weighing device is different between the clerk and the customer, such as the direction of the weighing device or the direction of the display device provided on the weighing device is changed, the usage of the weighing device depends on the mode of the weighing device that is assumed to be used. The operation subject of the weighing device may be determined.

  In the above example, the operating subject is the clerk in the normal mode or the registration-only mode, and the operating subject is the customer in the full self-mode. However, the operating subject can be determined in other modes. Is also good. For example, in the double scan mode in which the registration process is performed on both sides of the clerk on the customer side, the operating subject may be a clerk or a customer. Alternatively, in the double scan mode, the registration subject may be both a clerk and a customer, and a dedicated display when the registration subject is both a clerk and a customer may be provided.

  Note that the above embodiment is an example, and the specific configuration is not limited to the above embodiment, and includes a design and the like within a range not departing from the gist of the invention.

  For example, in the above embodiment, the POS terminal 20 has three types of operation modes (normal mode, full self mode, and semi self mode), but may have one or more of these operation modes. . For example, the POS terminal may operate in the normal mode or the semi-self mode only, may operate in the normal mode and the full self mode or the semi-self mode, or may operate in the semi-self mode and the full self mode. Also, when operating in the semi-self mode, it may operate only in the registration-only mode, may operate only in the accounting-only mode, or switch between both the registration-only mode and the accounting-only mode. Anything that can be done.

  The mode switching button 211a for switching the operation mode is a hardware key, but the operation mode is switched by a software key displayed on a display unit (the clerk-side display unit 210) instead of or in addition to the hardware key. You may do so. That is, a software key corresponding to the mode switching button 211a may be displayed instead of or in addition to the mode switching button 211a. The same applies to each button when a number of mode switching buttons corresponding to each of the operation modes are prepared.

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

  In the above embodiment, when transmitting the registration information to another terminal, the clerk specifies (selects) the terminal of the transmission destination (destination) of the registration information. May specify that the registration information is to be transmitted without specifying the destination terminal. That is, only the transmission 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 to be the destination according to a predetermined priority and registers the selected terminal. Submit information. The same applies to the case where the weight information is transmitted from the weighing device 30 to the POS terminal 20.

  For example, when transmitting the registration information from the first POS terminal 20-1 to the other terminals (the second POS terminal 20-2 and the third POS terminal 20-3), the predetermined priority is determined by the third POS terminal 20-3 in the full self mode. May be higher than the second POS terminal 20-2 in the normal mode (the registration information may be preferentially transmitted to the third POS terminal 20-3 in the full self mode).
