As shown in FIG. 1, the POS system 1 shown in FIG. 1 includes a store controller 10 and three POS terminals 20. The store controller 10 and the POS terminal 20 are connected to each other by a wired or wirelessly connected LAN (Local Area Network) 11. Hereinafter, when the first POS terminal 20-1, the second POS terminal 20-2, and the third POS terminal 20-3 are not particularly distinguished, they are collectively referred to as the POS terminal 20. The POS system 1 may further include a monitoring terminal (not shown) that displays the status (operation mode, processing status, etc.) of the POS terminal 20 and controls the POS terminal 20.

The configuration of the POS system 1 shown in FIG. 1 is an example. For example, in the POS system 1, the number of POS terminals 20 installed is not particularly limited. Further, the POS system 1 of the present embodiment may be configured not to include the store controller 10. If the configuration of the POS system 1 does not include the store controller 10, the store controller 10 may be used in another device (for example, one POS terminal 20 that is representative of the plurality of POS terminals 20). May be combined with the function as.

The POS system 1 can be introduced in various stores (convenience stores, supermarkets, etc.).

The store controller 10 is an information processing device that manages the POS system 1, manages the POS terminal 20 and the like in the POS system 1, and manages various information such as a product master. The store controller 10 appropriately transmits the latest product master to the POS terminal 20. The product master is a file that stores product information such as product identification information (for example, JAN code), product name (product name, item name), selling price, and discount information of each product. The store controller 10 acquires a product master reflecting the latest product information from an external device (for example, a server at the headquarters or a removable storage medium) and appropriately transmits the product master to the POS terminal 20.

The POS terminal 20 executes a product registration process for registering a product to be purchased. The operation of registering a product (product registration operation) is performed, for example, as an operation of scanning a barcode attached to a product using a scanner, an operation of a preset button or the like displayed on a product registration screen, or the like. By such a product registration operation, for example, product identification information is input to the POS terminal 20, and the POS terminal 20 acquires the product information corresponding to the input product identification information.

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

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

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

6 and 7 are diagrams for explaining the outline of the operation mode of the POS terminal 20. FIG. 6 is a diagram illustrating an outline of the normal mode. FIG. 6A is a schematic diagram showing the flow of processing (registration processing, settlement processing) and the operation of people (clerks, customers) in the normal mode, and FIG. 6B is the operation of the POS terminal 20 in the normal mode. It is a flowchart which showed the basic flow of. FIG. 6 is a diagram illustrating an outline of the full self mode. FIG. 7A 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. 7B is the operation of the POS terminal 20 in the full self mode. It is a flowchart which showed the basic flow of.

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

In the normal mode, the clerk registers the customer's purchased product on the clerk side (clerk side handy scanner unit 212, clerk side fixed scanner unit 216, clerk side display unit 210, key operation unit 211). That is, the POS terminal 20 performs the registration process of the purchased product by the operation of the clerk (scanning by the clerk side handy scanner unit 212 or the clerk side fixed scanner unit 216, touching the clerk side display unit 210, operating the key operation unit 211). Is executed (upper part of FIG. 6 (A)).

When the registration process by the clerk is completed, the customer confirms the total amount of the purchased products on the clerk side display unit 210, inserts money (cash) into the change machine 209, or operates the card settlement unit 208 to settle the payment. (Lower part of FIG. 6A). That is, the POS terminal 20 executes the settlement process by the customer's operation (inserting cash into the change machine 209, operating the card settlement unit 208) (lower part of FIG. 6A).

That is, in the normal mode, as shown in FIG. 6B, the clerk first scans the product (step S10: YES) and registers the product (step S11). After pressing the subtotal key (for example, the subtotal key displayed on the clerk side display unit 210 or the subtotal key arranged on the key operation unit 211) (step S30: YES), on the customer side, for example, the change machine 209 Settlement is performed by (step S50), and the process is completed. In step S30, the subtotal key is an operation key for completing the registration process, and may be referred to as a subtotal button, a registration completion key, a registration completion button, a checkout key, a checkout button, or the like.

The customer may wait until the registration process by the clerk is completed (until the total amount is fixed), but may insert cash into the change machine 209 before the registration process is completed. That is, the POS terminal 20 can accept payment during the registration process (upper part of FIG. 6A).

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

In addition, the clerk may wait until the customer's payment is completed (until the customer picks up the change or receipt), but may register the next customer's purchased product. That is, the POS terminal 20 can register the purchased product of the next customer during the settlement process (lower part of FIG. 6A). In addition, the clerk may be absent during the payment by the customer (lower part of FIG. 6A). That is, the reception of the customer may be completed during the settlement of the customer.

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

Further, in the normal mode, as described above, the clerk side executes the registration process, and the customer side of the own terminal executes the settlement process using the registration information generated in the registration process (see FIG. 6). In addition, the clerk executes the registration process and transmits the registration information generated in the registration process to another terminal (another terminal capable of executing the settlement process, for example, another POS terminal 20) (via LAN11). , Send directly to another terminal, or send to another terminal via the store controller 10 or a monitoring terminal (not shown). The same shall apply hereinafter), and the registration information generated in the registration process is coded (bar). It is also possible to execute the process of converting into a code (two-dimensional code, etc.), printing it on a medium, and issuing it as a bill. That is, the POS terminal 20 in the normal mode has a function of registering a product in the own terminal and making a payment at the own terminal, and a function of registering a product in the own terminal and making a payment in another terminal.

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

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

(Full self mode)
As shown in FIG. 7A, the full self mode is an operation mode in which the customer side executes the registration process and the customer side executes the settlement process. That is, as shown in FIG. 7B, in the full self mode POS terminal 20, the customer side is in both the registration mode and the accounting mode. That is, the POS terminal 20 in the full self-mode operates as the registration accounting mode when viewed throughout the registration process to the settlement process.

In the full self mode, the customer registers his / her purchased product on the customer side (customer side scanner units 206 and 207, customer side display unit 205). That is, the POS terminal 20 executes the registration process of the purchased product by the operation of the customer (scanning by the customer side scanner units 206 and 207, touching the customer side display unit 205) (upper part of FIG. 7A).

When the registration process is completed, the customer confirms the total amount of the purchased products on the customer side display unit 205, inserts cash into the change machine 209, or operates the card settlement unit 208 to settle the payment (FIG. 7 (A). ) Lower). That is, the POS terminal 20 executes the settlement process by the customer's operation (inserting cash into the change machine 209, operating the card settlement unit 208) (lower part of FIG. 7A).

That is, in the full self mode, as shown in FIG. 7B, the product is scanned or the like on the customer side (step S20: YES), and the product is registered (step S21). After pressing the registration completion key (for example, the registration completion key displayed on the customer side display unit 205) (step S40: YES), payment is performed on the customer side by, for example, the change machine 209 (step S50), and processing is performed. Is completed. The registration completion key according to step S40 is an operation key for completing the registration process, and may be referred to as a registration completion button, a subtotal key, a subtotal button, a checkout key, a checkout button, or the like.

In the full self mode, as described above, the customer side executes both the registration process and the settlement process, but the clerk side does not mean that nothing can be done. That is, even when the POS terminal 20 is operating in the full self mode, for example, the clerk side scanner units 212 and 216 scan the clerk code, display various information, and register the product. It is possible to do it. The state in which the registration process is executed on both the clerk side and the customer side (operation mode) may be referred to as a double scan mode.

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

In the semi-self mode, the clerk registers the customer's purchased product on the clerk side (the clerk side scanner unit 212, 216, the clerk side display unit 210, the key operation unit 211) on the first POS terminal 20-1 in the registration-only mode. To do. 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 units 212 and 216, the clerk side display unit 210, the key operation unit 211, etc.) (FIG. 8 (FIG. 8). A) 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, confirms the total amount of the purchased products on the display unit 210 on the clerk side, and inserts money into the change machine 209, or , The card settlement unit 208 is operated to settle the payment (lower part of FIG. 8A). That is, the second POS terminal 20-2 executes the settlement process by the operation of the customer (inserting money into the change machine 209, operating the card settlement unit 208) (lower part of FIG. 8A).

When the registration process is completed at the registration-only mode POS terminal 20 (first POS terminal 20-1 in the example of FIG. 8), the customer changes from the registration-only mode POS terminal 20 to the accounting-only mode POS terminal 20 (FIG. 8). In the example, it moves to the second POS terminal 20-2), but the destination POS terminal 20 (second POS terminal 20-2) is used for the settlement process of the registered POS terminal 20 (first POS terminal 20-1). Necessary information (registration information, etc.) is supplied.

Information required for settlement processing from the registration-only mode POS terminal 20 (first POS terminal 20-1 in the example of FIG. 8) to the accounting-only mode POS terminal 20 (second POS terminal 20-2 in the example of FIG. 8). As a supply method, a method of transmitting information necessary for settlement processing 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 registration. There is a method of issuing a medium (a medium on which a bar code or the like for acquiring information necessary for settlement processing is printed) on the POS terminal 20 in the dedicated mode.

The destination POS terminal 20 (the POS terminal 20 that executes the settlement process among the POS terminals 20 in the accounting-only mode) may be specified in the registration-only mode POS terminal 20. 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 settlement processing is printed) and reads the medium. It may be the POS terminal 20 of the destination.

That is, in the semi-self mode, the product is first registered on the clerk side of the POS terminal 20 (first POS terminal 20-1) in the registration-only mode. For example, as shown in FIG. 8B, the product is registered by scanning the scanner units 212 and 216 on the clerk side (step S10: YES) (step S11). After pressing the subtotal key (for example, the subtotal key displayed on the clerk side display unit 210 or the subtotal key arranged on the key operation unit 211) (step S30: YES), for example, the POS terminal 20 in the accounting-only mode (for example, When the second POS terminal 20-2) is designated (step S31: YES), the registration information is transmitted to the designated POS terminal 20 (step S32), and the process is completed.

In the example of FIG. 8B, when the product registration is completed, the subtotal key is first pressed, and then (after the subtotal key is pressed), the POS terminal 20 is specified. However, the product registration is completed. Occasionally, the processing procedure may be such that the POS terminal 20 is specified directly (without pressing the subtotal key). In the latter case, it is not necessary to display the subtotal key on the screen.

Subsequently, as shown in FIG. 8C, the POS terminal 20 (second POS terminal 20-2) designated by the registration-only mode POS terminal 20 (second POS terminal 20-2) receives the registration information. (Step S49: YES), the settlement is performed on the customer side, for example, by the change machine 209 (step S50), and the process is completed.

The clerk can register the purchased product of the next customer after transmitting the registration information (or after issuing the medium) (lower part of FIG. 8A). In addition, the clerk may be absent after transmitting the registration information (lower part of FIG. 8A).

In the example of FIG. 8, the second POS terminal 20-2 in the accounting-only mode executes the settlement process using the registration information of the product registered in the first POS terminal 20-1 in the registration-only mode. That is, the registration information used by the second POS terminal 20-2 in the accounting-only mode for the settlement process is the registration information of the product registered when the first POS terminal 20-1 is operating 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 the accounting ticket (registered trademark; the same applies hereinafter) can be issued), the second POS terminal 20 in the accounting-only mode 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 is operating as 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 the registration information of the product registered when the first POS terminal 20-1 is operating in the normal mode. That is, the second POS terminal 20-2 in the accounting-only mode may execute the settlement procedure using the registration information of the product registered when the first POS terminal 20-1 is operating in the normal mode.

When the clerk of the first POS terminal 20-1 completes the registration process (when trying to send registration information or issue a checkout ticket), the customer side makes a payment operation (change machine 209). If the insertion of money into the card and the operation of the card settlement unit 208) have already started, the transmission of registration information or the issuance of the checkout ticket may be prohibited, or the settlement operation may be cancelled. ..

Further, in the example of FIG. 8, the second POS terminal 20-2 receives the registration information (or reads the accounting ticket) and executes the settlement processing when operating as the accounting-only mode. However, if the settlement process can be executed after receiving the registration information (or after reading the checkout ticket), when the second POS terminal 20-2 receives the registration information (or reads the checkout ticket). The operation mode does not necessarily have to be the accounting-only mode.

As an example, the second POS terminal 20-2 receives registration information from another terminal (for example, the first POS terminal 20-1) when operating in the full self mode, and uses the registration information received from the other terminal. You may execute the settlement process. In addition, the second POS terminal 20-2 reads the checkout ticket issued by another terminal (for example, the first POS terminal 20-1) while operating in the full self mode, and the checkout 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 (registration information received from the other terminal as the settlement procedure in the accounting-only mode). To process). In addition, the second POS terminal 20-2 shifts from the full self mode to the accounting-only mode before executing the settlement processing using the accounting ticket issued by the other terminal (in the other terminal as the settlement procedure of the accounting-only mode). Process registration information based on issued bills).

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 registration information received from the other terminal (as a settlement procedure in the full self mode, etc.). You may process the registration information received from the terminal). Further, the second POS terminal 20-2 does not have to shift from the full self mode to the checkout mode before executing the checkout process using the checkout ticket issued by the other terminal (full self mode checkout procedure). Registration information based on the accounting voucher issued on another terminal may be processed). In these cases, data may be transmitted and received between the plurality of POS terminals 20, and registration settlement processing and the like may be performed between the plurality of POS terminals.

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

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

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

(Switching of operation mode (transition))
Subsequently, 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 changed) according to an explicit mode switching operation (also referred to as a mode transition operation) by the clerk. Specifically, the operation mode is switched according to the operation of the mode switching button 211a (see FIG. 3B) arranged at the uppermost stage and the rightmost end of the key operation unit 211.

Since the mode switching button 211a is arranged at the corner of the key operation unit 211, it is possible to reduce operation mistakes when 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, the mode switching button 211a which is the operation target is compared with the case where the mode switching button 211a is located near the center of the key operation unit 211. Since the number of other adjacent buttons is small, operation mistakes such as operating other buttons in a hurry are unlikely to occur, and the position of the mode switching button 211a to be operated can be instantly specified, so mode 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 (topmost and rightmost) 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 the clerk is on the customer side. You will be able to do it. That is, the clerk on the customer side cannot normally see each button of the key operation unit 211, but the mode switching button 211a existing at the upper right end of the key operation unit 211 is reached out from the customer side and groped. Since the mode switching button 211a, which is the operation target, can be easily recognized only by (feeling of the hand), the clerk on the customer side can perform the mode switching operation without moving to the clerk side.

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

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

Further, the POS terminal 20 can switch the operation mode without an explicit mode switching operation. For example, the POS terminal 20 is a condition related to time such as an elapsed time (for example, an elapsed time since the last operation) and a predetermined time (schedule), from another terminal (POS terminal 20, monitoring terminal, mobile terminal) or the like. The operation mode is switched based on the conditions related to the transmission and reception of information such as the mode switching instruction (mode switching instruction).

It should be noted that the POS terminal 20 switches when the operation mode of the own terminal is switched, regardless of whether the mode switching operation is performed by the clerk or not by the explicit mode switching operation. The later 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. Further, it is assumed that the third POS terminal 20-3 is in the full self mode. Further, in the following description, it is assumed that the POS terminal 20 switches its own operation mode each time the mode switching button 211a is operated (pressed). However, in the following description, for convenience, the description of the semi-self mode is omitted. Therefore, every time the mode switching button 211a is operated, the operation mode is basically switched from the normal mode to the full self mode, and the operation mode is changed from the full self mode. It is assumed that the operation mode is switched to the normal mode.

(Display example of POS terminal 20 in normal mode)
9 to 14 are display examples in the POS terminal 20 in the normal mode. Specifically, FIGS. 9 (A), 9 (B), 10 (A), 12 (A), and (B) are all clerk-side display units 210 of the first POS terminal 20-1 in the normal mode. It is a display example in. Further, FIGS. 10 (B), 11 (A) to (E), 13 (A), (B), and 14 (B) are all on the customer side of the first POS terminal 20-1 in the normal mode. This is a display example in the display unit 205.

FIG. 9A shows the display contents on the registration screen in the initial state on the clerk side display unit 210. In the following explanation, the initial state is a state in which processing is not in progress, for example, a state in which no product is registered yet, and no payment (settlement) has been made yet, unless otherwise specified. In a state (such as when the payment method has not been selected, cash has not been inserted, or gift certificates have been registered), and nothing has been done about the customer (such as when the membership card has not been read). is there.

In FIG. 9A, the tab area T1 on 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 to add the purchased product), and the registration process of the next customer is possible. That is, the first POS terminal 20-1 displays a new registration screen for the next customer while holding (memorizing) the display contents (registration contents) of the registration screen for the customer based on the operation of the clerk. In the example shown in FIG. 8A, there is only one tab (tab area T1), but the first POS terminal 20-1 displays a number of tabs according to the number of registration screens (number of customers) in progress (the number of tabs is displayed. The registration screen to be enabled (active) is switched according to the tab areas T1, T2, T3, ...) And the tab operation (pressing).

In the tab area T1, information for identifying the tab from other tabs (number “1” in the example of FIG. 9A) is displayed. Further, the tab area T1 is provided with a clerk-side amount display column HR01 for displaying the amount deposited from the customer. Further, although not displayed in the example shown in FIG. 9A, 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 (specifically, the normal mode) of the other terminal (second POS terminal 20-2). The image GA03 at the lower left of the screen shows the state (specifically, the full self mode) of another terminal (third POS terminal 20-3).

When the canned beer is registered by the clerk from the state where the first POS terminal 20-1 displays the registration screen of FIG. 9 (A) on the clerk side display unit 210, FIG. 9 (B) is displayed on the clerk side display unit 210. ) Is displayed as shown in the registration screen. The first POS terminal 20-1 starts a transaction for selling the product by registering the first product, here, registering the canned beer.

In FIG. 9B, the subtotal button BT10 at the lower right of the screen is a button for instructing the end of product registration. The clerk operates (touches) the subtotal button BT10 after the product registration is completed.

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

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

The 20-3 cash register button BT13 is a button for designating the 20-3 cash register (third POS terminal 20-3). The clerk operates the 20-3 cash register button BT13 when designating 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 checkout button BT15 is a button for the printing unit 213 to issue a checkout ticket. The clerk operates the checkout button BT15 when the POS terminal 20 (the POS terminal 20 in which the customer has read the checkout) executes the process.

When comparing the POS terminal 20 in the normal mode and the POS terminal 20 in the full self mode as the POS terminal 20 to which the registration information is transmitted, the POS terminal 20 in the full self mode is better than the POS terminal 20 in the normal mode. Is preferable as a destination for transmitting registration information. Since the POS terminal 20 in the normal mode is basically operated by a clerk (see FIG. 5A), processing (for example, registration processing, customer support, etc.) continuously exists and is registered. Even if you send information, there is a high possibility that it will not 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 support from the clerk. On the other hand, the full self-mode POS terminal 20 can transmit the registration information immediately if there is no customer, and even if there is a customer, it is sufficient to simply process them in order. This is because problems such as are unlikely to occur.

In view of the above, the store clerk is notified whether or not the POS terminal 20 as the destination of the registration information is preferable, or which is more preferable when there are a plurality of destinations of the registration information. As an example, in FIG. 9B, the outline portion of the 20-3 cash register button BT13 corresponding to the third POS terminal 20-3 in the full self mode, which is relatively preferable as the transmission destination of the registration information, is shown by a solid line, and the registration information is transmitted. The outline portion of the 20-2 cash register button BT12 corresponding to the second POS terminal 20-2 in the relatively unfavorable normal mode is shown by a broken line. The above-mentioned notification by the contour portion is an example, and the clerk determines whether or not the POS terminal 20 as the destination of the registration information is preferable, or which is more preferable when there are a plurality of destinations of the registration information. The notification mode is not limited as long as it can be recognized. For example, those who are relatively unfavorable may display the background color of the button in gray down, or may add a penalty mark or a diagonal line to the entire button. Further, the display size, shape, and display position of the button may be different depending on whether or not it is preferable as the POS terminal 20 to which the registration information is transmitted, and some information (“priority” or “recommended”” may be given to the button. You may attach a badge-like image, etc.

When cash is inserted by a customer from the state where the registration screen shown in FIG. 9B is displayed on the clerk side display unit 210, the first POS terminal 20-1 is inserted into the clerk side amount display column HR01 at the upper right of the screen. When the amount of money, for example, 500 yen, is invested, the numerical value of "500" is displayed. Since cash has not been inserted at the stage shown in FIG. 9B, the display column on the right side of the screen on which "Custody" is written shows the numerical value corresponding to the amount of money inserted. The numerical value of "0" is displayed. Further, when cash is inserted, the payment is made at the own terminal (first POS terminal 20-1) instead of the other terminals (second POS terminal 20-2, third POS terminal 20-3). Therefore, the buttons (20-2 cash register button BT12, 20-3 cash register button BT13, checkout button BT15) used when making a payment at other terminals (2nd POS terminal 20-2, 3rd POS terminal 20-3) are used. It may be hidden (may be erased).

When the registration of the product is completed and the subtotal button BT10 is operated by the clerk in the first POS terminal 20-1 without cash being inserted by the customer, the display unit 210 on the clerk side shows FIG. 10 (A). The small screen (small window) SG02 is superimposed on the registration screen and displayed. This small screen SG02 notifies the clerk of payment-related information (total amount, device deposit amount (deposit amount)). Here, in addition to the above-mentioned "canned beer", "asparagus" and "glue lunch" are registered as products, the total amount of the products is 803 yen, and the amount of cash input to the change machine 209 is 0 yen ( An example is shown in which cash is not inserted.

As shown in FIG. 10A, the first POS terminal 20-1 is used as a button for selecting payment by a code payment service (hereinafter referred to as “code payment”) together with a small screen SG02 on the clerk side display unit 210. , Clerk side cash register read button BT21, customer side cash register read button BT22, company A code display button BT23, company B code display button BT24, and other payment button BT25 are displayed.

(Modification example)
Hereinafter, a modified example of the above embodiment will be described. In the above example, when the mobile terminal reading payment method is performed, the POS terminal 20 once displays the payment method selection screen shown in FIG. 17 (A), and the company A payment code display button or the company B payment code display button of the company A payment image. After the company B payment code display button of the company payment image is operated, the payment code is displayed on the payment code screen shown in FIG. 13 (B), but as shown in FIG. 23, the payment code is displayed on the payment method selection screen. May be displayed. In the example shown in FIG. 23, the POS terminal 20 directly displays the company A payment code on the company A payment image together with the company A payment code read button, and displays the company B payment code on the company B payment image together with the company B payment code read button. Display directly. In this way, instead of displaying the payment code display button on the payment method selection screen and displaying the payment code when the payment code display button is operated, the payment code is directly displayed on the payment method selection screen. As a result, the labor of the customer's operation can be reduced by one operation. Therefore, the settlement process can be performed efficiently.

Further, in FIG. 23, when displaying the company A payment image, the company B payment image, and the cash payment button, the cash payment button is displayed between the company A payment image and the company B payment image. In this way, when displaying payment images by different payment providers, the payment images are read by talking and displaying a plurality of payment images by sandwiching an image other than the payment image without arranging the payment images next to each other. It is possible to prevent the payment code from being mistaken.

Further, in the above example, the payment method is determined each time in each operation mode of the POS terminal 20, but for example, the settlement method may be determined according to the operation mode. Further, the payment method determined here is a provisional payment method, and the provisional payment method may be changed.

For example, the payment method in the normal mode may be tentatively determined as the mobile terminal read payment method, and the payment method in the full self mode may be determined as the customer side POS read payment method. In this case, a screen corresponding to the tentatively determined payment method may be displayed as a default on the clerk side display unit 210 and the customer side display unit 205 so that the payment method to be changed as appropriate can be selected.

In the above example, the card payment unit 208 can read a credit card or a prepaid card (electronic money), but may be able to read another card, for example, a membership card. The membership card here may be a membership card at a store where the POS terminal 20 is installed, or a membership card of a group or the like including the store.

If the membership card or prepaid card stores information on points that can be used for payment (hereinafter referred to as "payment points"), the card payment unit 208 reads and writes the information on the payment points. May be possible. Further, the customer side display unit 205 may be provided with a point display unit for displaying payment points. By providing the point display unit, the customer can easily recognize the payment points that can be used for payment, and the convenience of the customer can be enhanced. Further, the customer side display unit 205 may be provided with a point use button that allows the payment points to be used for payment. By providing a point use button, it becomes easier for customers to use payment points.

The payment points may be used only for payment by cash, credit card, or electronic money, or may be used for a plurality of these payments. Further, the payment points displayed on the customer side display unit 205 may be displayed from the time when the membership card is inserted into the card payment unit 208. For example, the product has been registered since the product was registered. It may be displayed until after the registration of the product is completed, or it may be displayed when the payment is made after the registration of the product is completed. By displaying the settlement points from the time when the product is registered, it is possible to smoothly prepare money for settlement in cash settlement. In addition, depending on the payment point, it can be used as a reference for selecting a payment method. For example, when there are many payment points remaining, the payment amount will be small, so select cash payment, and when there are few payment points remaining, the payment amount will be large, so select credit card payment. You can also.

In the above example, in the normal mode of the POS terminal 20, when the subtotal button BT10 is displayed, the 20-2 cash register button BT12 and the 20-3 cash register button BT13 are displayed, but the subtotal button BT10 is displayed. The 20-2 cash register button BT12 and the 20-3 cash register button BT13 may not be displayed when they are displayed. In this case, after pressing the subtotal button BT10, the 20-2 cash register button BT12 or the 20-3 cash register button BT13 may be displayed. By displaying the 20-2 cash register button BT12 and the 20-3 cash register button BT13 after pressing the subtotal button BT10, it is possible to facilitate the settlement process on the other POS terminal 20 even in the normal mode.

Further, in the above example, the subtotal button BT10 is not displayed in the registration-only mode of the semi-self mode, but the subtotal button BT10 is displayed and the 20-2 cash register button BT12 and the 20-3 cash register button BT13 are not displayed. You may. In this case, the 20-2 cash register button BT12 or the 20-3 cash register button BT13 may be displayed after the subtotal button BT10 is operated. Further, the 20-2 cash register button BT12 and the 20-3 cash register button BT13 may be displayed together with the subtotal button BT10.

Further, in the above example, when the POS terminal 20 selects payment by credit card at the time of product registration in the normal mode, the credit payment screen is displayed on the customer side in the settlement process after the subtotal button BT10 is pressed. It is displayed in 205. On the other hand, the POS terminal 20 may display the credit settlement screen on the customer side display unit 205 at the stage before the subtotal button BT10 is pressed at the time when the payment by the credit card is selected. In this case, the credit settlement screen may continue to be displayed even when the subtotal button BT10 is operated. Further, in this case, the POS terminal 20 may allow the credit card to be inserted into the card payment unit 208 before the registration of the product is completed.

Then, when the product registration is completed, in other words, when the subtotal button BT10 is pressed, if a credit card is inserted in the card payment unit 208, payment by the credit card is made when the subtotal button BT10 is pressed. May be started. When payment by credit card is started when the subtotal button BT10 is pressed, the credit payment screen is not displayed, and for example, a notification screen for notifying that payment is progressing by credit card is displayed on the customer side. It may be displayed in unit 205. Further, when making a payment using electronic money, if the electronic money is not a contactless IC but a contact type IC or the like and is inserted into the card payment unit 208 for payment, the payment is made with a credit card. Payment by electronic money may be performed by the same procedure. Further, in the case of payment by electronic money using a contactless IC, for example, when payment by electronic money is selected before the product registration is completed, the position where the prepaid card is brought close to is conspicuous, for example, a lamp. It may be lit or blinked.

Further, in the above example, the small screen SG01 shown in FIG. 9B is displayed when the product is registered. Further, when the payment method is not selected during the product registration and the subtotal button BT10 is operated to shift to the settlement process, the payment method determination screen shown in FIG. 10B is displayed on the customer side display unit 205. indicate. The display of the small screen SG01 or the payment method determination screen may be appropriately changed according to the state of the payment unit of the POS terminal 20, for example. For example, if there is a problem in inserting or withdrawing cash in the change machine 209, or if the change is near full or near end, the cash settlement button BT41 may not be displayed. Further, when there is a problem in inserting the card by the card settlement unit 208, the credit settlement button BT42 may not be displayed. Further, when there is a problem in reading the adjacent cards by the card payment unit 208, the electronic money payment button BT43 may not be displayed. Further, in these cases, instead of displaying each button, the display may be lightened, grayed out, or the display may be crossed.

It should be noted 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 that does not deviate from the gist of the invention.

For example, in the above example, 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 only in the normal mode or the semi-self mode, 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. In addition, when operating in the semi-self mode, it may operate only in the registration-only mode, it may operate only in the accounting-only mode, or it may be used by switching between both the registration-only mode and the accounting-only mode. It may be something that can be done.

Further, in the above example, the POS terminal 20 included in the POS system 1 is provided with a clerk-side processing unit and a customer-side processing unit, and product brain registration is possible in both the clerk-side processing unit and the customer-side processing unit. Yes, the settlement process is possible for both the product registered by the own terminal and the product registered by the other terminal in the POS system 1, but the POS terminal 20 may be in another mode. For example, a POS system dedicated to registration may be used, of which one or both of the clerk-side processing unit and the customer-side processing unit are provided, and the product can be registered by either or both of the clerk-side processing unit and the customer-side processing unit. The POS terminal may be included in the POS system. Alternatively, a POS terminal capable of settlement processing of the registered product on at least one of the own terminal and the other terminal in the POS system may be included.

Further, in the above example, when the subtotal key is operated, the POS terminal 20 superimposes the small screen SG02 on the registration screen (FIG. 10 (A)), but the POS terminal 20 displays the subtotal. When the key is operated, instead of (switching) the registration screen, a subplanning surface for displaying information or the like displayed on the small screen SG02 may be displayed.

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

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

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

The predetermined priority is, for example, when the registration information is transmitted from the first POS terminal 20-1 to another terminal (second POS terminal 20-2, third POS terminal 20-3), the third POS terminal 20-3 in the full self mode May be higher than that of the second POS terminal 20-2 in the normal mode (registration information may be preferentially transmitted to the third POS terminal 20-3 in the full self mode).

Further, in the above example, the store clerk side processing unit is provided with the store clerk side handy scanner unit 212 and the store clerk side fixed scanner unit 216, but only the store clerk side handy scanner unit 212 or the store clerk side fixed scanner unit 216 is provided. It may have been. Further, although the customer-side fixed scanner unit 206 and the customer-side handy scanner unit 207 are provided, only the customer-side fixed scanner unit 206 and the customer-side handy scanner unit 207 may be provided.

Further, in the above example, in the normal mode, the clerk selects either the display of the payment code on the POS terminal 20 or the reading of the payment code by the POS terminal 20, and in the full self mode, the customer selects the payment code for the POS terminal 20. Either display or reading of the payment code by the POS terminal 20 is selected, but either the display of the payment code on the POS terminal 20 or the reading of the payment code by the POS terminal 20 is automatic based on the selection conditions based on the predetermined conditions. It may be decided as a target. For example, the payment method may be automatically selected according to the operation mode of the POS terminal 20 that performs the registration process. For example, when the POS terminal 20 is in the normal mode, the customer does not perform the registration process and the time allowance for displaying the payment code of the mobile terminal 40 becomes large. Therefore, the payment is made by reading the payment code by the POS terminal 20 and is full. In the self-mode, the customer registers and the time margin for displaying the payment code of the mobile terminal 40 is reduced, so that the payment may be made by displaying the payment code on the POS terminal 20.

Further, in this case, the payment method once selected may be reselected. For example, according to the above example, when the POS terminal 20 is in the normal mode, the payment method is set to read the payment code by the POS terminal 20, but the payment method is changed to the method in which the POS terminal 20 displays the payment code. A change button may be provided. The payment method change button may be provided in the clerk side processing unit, for example, the clerk side display unit 210, or may be provided in the customer side processing unit, for example, the customer side display unit 205. Alternatively, it may be provided in both the clerk side processing unit and the customer side processing unit.

Further, the payment method may be set in advance by the store or the like based on a predetermined selection condition. Further, the selection condition may be a condition other than the operation mode. For example, a time zone such as a busy time zone or a quiet time zone may be used as a selection condition, or the customer's characteristics, such as gender and age, may be determined and the customer's characteristics may be used as a selection condition. Alternatively, the number of registered products or the number of types may be used as a selection condition, or a combination of these conditions may be used as a selection condition.

Further, the predetermined selection condition is the type of electronic money used for payment, and the mode of payment may be determined based on the type of electronic money used for payment. For example, when the electronic money A is used, the payment code is displayed on the customer side display unit 205, and when the electronic money B is used, the payment code displayed on the mobile terminal 40 is read. May be good. In addition, the passage of time such as the time elapsed since the payment code is displayed may be set as a predetermined selection condition, and the mode of payment may be changed when the predetermined time has elapsed. For example, after displaying the payment code on the customer side display unit 205, if the payment is not performed for a certain period of time, the payment may be shifted to the payment that reads the payment code displayed on the mobile terminal 40. In this case, when it is difficult to read the payment code with one display, the payment code may be easily read by the other display, and the reading may be performed quickly and the payment may proceed smoothly.

Further, the predetermined selection condition may be, for example, an attribute of the customer. The attributes of the customer may be attributes such as the age, gender, and whereabouts of the customer, or may be the usage history of payment. The customer's attributes may be acquired by information linked by the customer's membership card or the like, manual input by the clerk or the customer, image recognition, face authentication, or the like. Since the payment mode is selected from the customer attributes, it is possible to determine the payment mode suitable for the customer attributes.

Further, in the above example, the payment method is determined by the clerk selecting the payment method and operating the payment method selection button, but the payment method may be selected by another selection. For example, the clerk payment method may not be selected, and the payment may be made by a payment method predetermined according to the operation mode. Further, the payment method may be selected by operating the device provided outside the store controller 10 or other POS terminal 20.

Further, in the above example, when the payment code fails to be read and an error occurs, the occurrence of the error may be notified by an error sound, or the cause of the error and the countermeasures may be notified as an error message. Good. The speaker that emits an error sound may be directed to the customer side or the clerk side. The error message may be displayed on either one of the clerk side display unit 210 and the customer side display unit 205, or may be displayed on both sides. When the error message is displayed on both the clerk side display unit 210 and the customer side display unit 205, the contents may be the same or different. The mode of notifying these error contents may be set according to the contents of the error.

For example, a plurality of errors may be classified according to their contents, an error code may be attached, and a countermeasure for each error code may be determined. For example, an error caused by non-member use is given an error code 001, an error caused by an invalid one-time key is given an error code 002, and the credit card used for code payment is prohibited. Error code 005 is attached to the error caused by. The error caused by the prohibition of use of the credit card used for code payment is an error that may cause unauthorized use, but the error that may cause unauthorized use is the credit used for code payment. There are errors such as the card being a stolen reported card or a blacklist card. In the case of these errors that may be used illegally, the clerk may be alerted to the fraudulent use.

As an example when an error occurs, for example, in the case of an error with error code 001, as shown in FIG. 24, the error message "I am not a member of XX Pay" is displayed on the clerk side display unit 210 and the customer side display unit 205. It is displayed on both sides of. In addition, in the error of error code 002, the error message "Invalid one-time key" is displayed on the clerk side display unit 210, and "Please update the payment screen again" on the customer side display unit 205. Error message is displayed. At this time, the error message displayed on the clerk side display unit 210 is a message dedicated to the clerk side display unit 210, and the error message displayed on the customer side display unit 205 is a message dedicated to the customer side display unit 205. ..

In addition, in the error of the error code 005, the error message "The credit card has been suspended is displayed" is displayed on the clerk side display unit 210, and the error message is not displayed on the customer side display unit 205, or simply "An error has occurred. The message "Yes" is displayed. By such a response, it is possible to call the clerk's attention to unauthorized use without the customer's awareness. Similar measures are taken for errors that may be fraudulently used, such as errors such as the credit card used for code payment being a stolen reported card or a blacklist card.

Further, when the communication between the POS system 1 and the payment operator 70 fails in the code payment, the POS system 1 cannot grasp whether or not the payment is completed. In this case, the printing unit 213 may print and issue a receipt containing the message "a transaction with unknown settlement has occurred". In this case, the printing unit 213 can change its orientation between the clerk side and the customer side. Therefore, for example, when the printing unit 213 is facing the customer side, the printing unit 213 is temporarily directed to the clerk side. Then, a message or an icon prompting the clerk to receive the receipt printed and issued by the printing unit 213 may be displayed on the clerk side display unit 210.

Further, when the POS terminal 20 determines that the payment code cannot be displayed on the clerk side display unit 210 or the customer side display unit 205, the POS terminal 20 makes a payment by scanning the payment code displayed on the mobile terminal 40 with a scanner. To. Therefore, when the POS terminal 20 determines that the payment code cannot be displayed on the clerk side display unit 210 or the customer side display unit 205, the POS terminal 20 prompts the customer to display the payment code on the mobile terminal 40. When it is determined that the payment code cannot be displayed on the clerk side display unit 210 or the customer side display unit 205, for example, the clerk side display unit 210 or the customer side display unit 205 that displays the payment code is a full-color display device. It is not a (full-color liquid crystal display device) but a "7-segment display" or a "black and white display".
