The ROM 202 is a read-only memory, and stores various information used by the CPU 201 including programs.

  The RAM 203 is a read / write memory and stores various information. For example, the RAM 203 stores information obtained from the outside (for example, a product master obtained from the store controller 10), information generated in the process (for example, registration information (registered data) generated in a registration process of registering a product), purchase, (E.g., settlement information generated in a settlement process for adjusting (settlement) a product).

  The hard disk 204 stores various information. The hard disk 204 may store, for example, a program executed by the CPU 201 instead of the ROM 202. Further, instead of the RAM 203, information obtained from outside or information generated in the processing may be stored.

The customer-side display unit 205 is a touch display for the customer, displays various information to the customer, and receives various inputs from the customer.
The customer side scanner unit 206 is a customer scanner unit, and optically reads various information.
For example, the customer-side scanner unit 206 optically converts a barcode (product code or the like) attached to a product or a code (barcode, two-dimensional code or the like) printed on a bill (registered trademark). read. In addition to the above, the customer-side scanner unit 206 further includes codes (barcodes, barcodes, and coupons) printed on gift certificates (commodity coupons, coupons, and special treatment coupons) and various cards (eg, membership cards, point cards, and the like). (Dimensional code, etc.).

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

  The card settlement unit 208 is a settlement mechanism using various cards (a credit card, a prepaid card such as a transportation card, a point card, and the like). The card settlement unit 208 includes a card recognition unit (reading unit), a display unit, and an operation unit. The card recognition unit magnetically or electrically reads information of various cards. The read information is used for settlement (payment) of the purchased product. The card recognizing unit uses the recognized information for the settlement (payment) of the purchased product this time (that is, in the case of a credit card payment, in the case of a prepaid card payment, in the case of a prepaid card payment, the point holding points of the point card are used). In addition to using (consuming), and not using the information recognized in the settlement (payment) of the purchased product this time (for example, when giving a privilege by presenting a credit card, when giving points to a point card) Etc.), various cards may be recognized. Note that the card settlement unit 208 of the present embodiment includes a card recognition unit (reading unit), a display unit, and an operation unit, but the card settlement unit 208 only needs to include at least a card recognition unit. Although the card recognition unit of the present embodiment corresponds to a contact type card (IC card, magnetic card), a non-contact type card (IC card) can be used instead of or in addition to a contact type card. May be one corresponding to.

  The change machine 209 (cash settlement unit) is a cash settlement mechanism, has a bill and coin insertion slot, a bill and coin ejection slot, calculates the amount of money to be inserted into the slot, and calculates the amount of money to be inserted and the purchase amount. The change amount as the difference is calculated, and the change is discharged from the discharge port. The change machine 209 is directed to the customer side and is operated by the customer. When bills or coins are inserted into the insertion slot, the detection is performed by a sensor (detection of the insertion, detection of the number of denominations, and the like). The settlement section is formed by the card settlement section 208 and the change machine 209.

The clerk-side display unit 210 is a touch display for the clerk, displays various information to the clerk, and receives various inputs from the clerk.
The key operation unit 211 includes various keys (hardware keys and buttons) and receives various inputs from a clerk.
The clerk-side scanner unit 212 is a clerk-side scanner unit, and optically reads various types of information. For example, the clerk-side scanner unit 212 optically reads a bar code attached to a product or a clerk code attached to a name tag of a clerk. In addition to the above, the clerk-side scanner unit 212 may read a code printed on a bill, a gift certificate, or a code printed on various cards.

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

  The printing unit 213 prints and issues various media (receipts, bills, etc.). The printing unit 213 can be rotatably changed from the clerk side to the customer side and from the customer side to the clerk side (direction of the medium issuing port). The orientation of the printing unit 213 may be changed manually, or may be automatically changed (mechanically controlled or the like) based on, for example, switching of an operation mode (details will be described later). The correctness of the orientation of the printing unit 213 may be detected by a sensor or the like. Switching of the operation mode is also referred to as transition of the operation mode.

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

(Overview of each operation mode)
Next, the operation mode of the POS terminal 20 will be described. The POS terminal 20 has a plurality of operation modes. This operation mode is an operation mode during normal business (operation mode relating to registration processing and settlement processing), a totaling mode for totalizing and inquiring sales and the amount of money, etc. It does not include the maintenance mode when performing, the training mode when newcomers train, and the like.

  FIG. 5 is a diagram illustrating an outline of the operation mode of the POS terminal 20. The POS terminal 20 has, for example, three types of operation modes shown in FIG. 5A (a normal mode (standard mode), a full self mode, and a semi self mode (accounting only mode)). The POS terminal 20 may have a normal mode (restricted mode) shown in FIG. 5B instead of or in addition to the normal mode (standard mode) shown in FIG. Further, the POS terminal 20 may have a semi-self mode (registration only mode) shown in FIG. 5B instead of or in addition to the normal mode (standard mode) shown in FIG. Further, the POS terminal 20 may have a semi-self mode (registration only mode) shown in FIG. 5B instead of or in addition to the semi-self mode (payment only mode) shown in FIG.

  In FIG. 5 (A), a column indicates each operation mode, and a row indicates each function (“product registration (clerk side)”, “product registration (customer side)”, “money insertion”,. Reading of a cash voucher ”). The same applies to FIG. 5B (however, illustration of each function is omitted in FIG. 5B).

  In FIG. 5A (the same applies to FIG. 5B), “〇” in a column specified from a column and a row indicates that the function of the row is enabled in the operation mode of the column. . For example, "@" in a column specified from the column "normal mode (standard mode)" and the row "product registration (clerk side)" indicates that the product registration (clerk side) is valid in the normal mode (standard mode). To the effect. Further, "-" in the column specified from the column and the row indicates that the function of the row is invalidated in the operation mode of the column. For example, "-" in the column specified from the column "normal mode" and the row "product registration (customer side)" indicates that the product registration (customer side) is invalid in the normal mode.

(Description of each function)
Hereinafter, an outline of each function shown in FIG.

(Product registration (clerk side))
“Product registration (clerk side)” is a function of registering a purchased product on the clerk side (the clerk side scanner section 212, the clerk side display section 210, the key operation section 211). In other words, the function is to execute the registration processing 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, operation of the key operation unit 211).

(Product registration (customer side))
“Product registration (customer side)” is a function of registering a purchased product on the customer side (customer side scanner unit 206, customer side display unit 205). In other words, this function is to execute a registration process of a purchased product by a customer operation (scan by the customer-side scanner unit 206, touch on the customer-side display unit 205).

(Money insertion)
“Money insertion” is a function of accepting the insertion of money (banknotes and coins). In other words, the function is to accept the operation of settlement by cash (input of money into the change machine 209).

(Send registration information to other terminals)
The “transmission of registration information to another terminal” is to transmit 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) (directly to another terminal). This is a function of transmitting or indirectly transmitting to another terminal via the store controller 10 or the monitoring terminal.

(Issue of banknotes)
“Issue a bill” is a function of encoding registration information and the like generated in the registration process and issuing a printed medium (a bill).

(Reception of registration information from other terminals)
“Reception of registration information from another terminal” means receiving registration information generated in the registration processing of another terminal (directly receiving from another terminal, or indirectly via the store controller 10 or the monitoring terminal or the like). This function is received from another terminal. Note that the terminal that has received the registration information from the other terminal executes a settlement process based on the registration information.

(Reading of the bill)
“Reading a bill” is a function of reading a bill (specifically, a code printed on the bill or coded information). Note that the terminal that has read the bill issued at the other terminal executes the settlement process based on the registration information obtained by reading the bill.

(Explanation of each operation mode)
Subsequently, an outline of each operation mode shown in FIGS. 5A and 5B will be described.

(Normal mode (standard mode))
As shown in FIG. 5A, the normal mode (standard mode) is an operation mode in which merchandise registration (clerk side) is set to valid “〇” and merchandise registration (customer side) is set to invalid “−”. That is, the normal mode (standard mode) is an operation mode in which the clerk performs the registration process without performing the registration process on the customer side.

  In the normal mode (standard mode), as shown in FIG. 5 (A), insertion of money, transmission of registration information to another terminal, and issuance of a cash voucher are all set to valid “有効”. This is the operation mode. That is, in the normal mode (standard mode), it is possible to execute the settlement process after the registration process on the side of the clerk at the own terminal or at another terminal. Specifically, in the normal mode (standard mode), the payment process is executed by the own terminal by accepting the insertion of money into the change machine 209, and the registration information is transmitted to the other terminal (or the bill is transmitted to the terminal). (By issuing it) causes another terminal to execute the settlement process.

  In addition, the normal mode (standard mode) is an operation mode in which both the reception of registration information from another terminal and the reading of a bill are valid “動作”, as shown in FIG. That is, in the normal mode (standard mode), it is possible to execute the settlement process based on the registration information generated in another terminal. Note that the settlement process after receiving the registration information (or after reading the bill) may be executed as the semi-self mode in FIG. That is, when the registration information is received (or the bill is read) in the normal mode (standard mode), the normal mode (standard mode) is automatically changed to the semi-self mode (accounting-only mode) (clerk). May be requested), and the settlement process may be executed in the semi-self mode (accounting-only mode). In addition, when the settlement process is executed after shifting to the semi-self mode (accounting-only mode), the mode automatically changes from the semi-self mode (accounting-only mode) to the normal mode (standard mode) (a permission from a clerk may be requested). It may be shifted (returned) or may remain in the semi-self mode (accounting-only mode).

  In the normal mode (standard mode), at least one of reception of registration information from another terminal and reading of a bill may be set to invalid “-”.

(Full self mode)
The full self mode is an operation mode in which merchandise registration (customer side) is valid “〇” as shown in FIG. That is, the full self mode is an operation mode on the premise of the registration process on the customer side. However, in the full self mode, the product registration (clerk side) is also set to “有効”. In other words, the full self mode is an operation mode that presumes the registration process on the customer side and also allows the registration process on the clerk side. The state where the registration process is performed on both the customer side and the clerk side may be referred to as a double scan mode.

  In the example shown in FIG. 5A, in the full self mode, the merchandise registration (clerk side) is set to valid “〇”, but in the full self mode, the merchandise registration (clerk side) is set to invalid “−”. Is also good.

  In the full self mode, as shown in FIG. 5 (A), an operation mode in which the insertion of money is valid “送信”, and the transmission of registration information to another terminal and the issuance of a banknote are invalid “−”. It is. That is, the full self mode is an operation mode on the premise of the settlement process in the terminal.

  In the full self mode, as shown in FIG. 5A, similarly to the normal mode (standard mode), both the reception of registration information from another terminal and the reading of a bill are valid “〇”. Operating mode. That is, as in the normal mode (standard mode), in the full self mode, it is possible to execute a settlement process based on registration information generated in another terminal. Note that the settlement process after receiving the registration information (or after reading the bill) may be executed as the semi-self mode in FIG. That is, when the registration information is received (or the bill is read) in the full self mode, the mode automatically shifts from the full self mode to the semi self mode (accounting only mode), and the semi self mode (accounting mode). The settlement process may be executed as a dedicated mode. Further, when the mode is shifted to the semi-self mode (accounting-only mode) and the settlement process is executed, the mode may be automatically shifted (returned) from the semi-self mode (accounting-only mode) to the full self-mode, or the semi-self mode ( (Accounting-only mode).

(Semi-self mode (accounting only mode))
In the semi-self mode (accounting-only mode), as shown in FIG. 5 (A), reception of registration information from another terminal, reading of a voucher, and insertion of money are set to valid “〇”, and product registration (clerk side) And the product registration (customer side) is invalid (-). In other words, the semi-self mode (accounting-only mode) is an operation mode in which the self-terminal does not execute the registration process, and executes the settlement process exclusively based on the registration information generated in another terminal. In the semi-self mode (accounting-only mode), the operation mode does not execute the registration process (because no registration information is generated). Therefore, as shown in FIG. The issuance of accounting vouchers is also invalid (-).

(Normal mode (Limited mode))
In the normal mode (restricted mode), as shown in FIG. 5 (B), the registration information is transmitted to another terminal and issuance of a check voucher which is set to be valid “〇” in the normal mode (standard mode) of FIG. 5 (A). Are invalid "-". That is, the normal mode (restricted mode) is an operation mode in which the function of allowing another terminal to execute the payment process, which is permitted in the normal mode (standard mode), is limited.

(Semi-self mode (registration only mode))
In the semi-self mode (registration only mode), as shown in FIG. 5 (B), product registration (store clerk), transmission of registration information to other terminals, and issuance of accounting voucher are set to valid “〇”, and product registration ( This is an operation mode in which the customer side), insertion of money, reception of registration information from another terminal, and reading of a bill are invalidated by "-". That is, the semi-self mode (registration only mode) is an operation mode in which the registration processing is executed exclusively in the own terminal and the settlement processing is executed in another terminal. Since the semi-self mode (registration only mode) is premised on the registration operation by the clerk, the product registration (customer side) is set to invalid "-".

(About enabling and disabling functions)
Note that, in the above description, the POS terminal 20 performs various functions (product registration (clerk side), product registration (customer side) in FIG. .., And the reading of the bill is different between the valid “有効” and the invalid “−”. In other words, in the above description, the POS terminal 20 has all the functions (product registration (clerk side), product registration (customer side), insertion of money,... It has been described that some of the functions are invalidated in accordance with the operation mode (for example, as shown in FIG. 5A, the POS terminal 20 is a product when in the normal mode (standard mode)). The registration (customer side) is invalidated "-", and in the full self mode, transmission of registration information to another terminal and issuance of a banknote are invalidated "-").

  However, the POS terminal 20 may have different functions that can be executed according to the operation mode, and the POS terminal 20 necessarily has all the functions originally, and some of the functions are invalidated according to the operation mode. It is not necessary to adopt such a configuration. For example, the POS terminal 20 does not have all functions (programs for realizing the functions) from the beginning, but is required in the operation mode according to the operation mode (for example, when switching the operation mode). A program for realizing a function (a function corresponding to the function marked as “〇” in FIG. 5) is acquired from the outside (for example, the store controller 10, a monitoring terminal, a server (cloud or the like) outside the store, etc.) and executed. If a program for realizing a function that can be set in the operation mode and a function unnecessary for the operation mode (a function corresponding to a function marked as “-” in FIG. 5) is present (if the program is to be retained), the program is executed. It may be in an unexecutable state (for example, it may be deleted). Note that a program for realizing a necessary function may be acquired and executed after a program for realizing an unnecessary function is made unexecutable. Further, for example, when switching the operation mode, the POS terminal 20 temporarily disables all programs irrespective of the operation mode of the transition destination, and then realizes a function required in the operation mode. The program may be acquired from the outside to make it executable. In other words, the configuration of the POS terminal 20 may be such that some of the originally provided various functions are disabled “−” according to the operation mode, or the necessary functions may be set according to the operation mode. It is also possible to provide only appropriate functions appropriately.

  The normal mode (standard mode), full self mode, semi-self mode (accounting-only mode), normal mode (restricted mode), and semi-self mode (registration-only mode) in FIG. 5B have been described above. However, the following description will focus on the normal mode (standard mode), the full self mode, and the semi self mode (accounting only mode) of FIG. In the following description, the normal mode (standard mode) may be simply referred to as a normal mode. The semi-self mode (accounting-only mode) may be simply referred to as a semi-self mode.

(Switch operation mode (transition))
Next, switching (shifting) of the operation mode of the POS terminal 20 will be described. The operation mode of the POS terminal 20 is basically switched according to an explicit mode switching operation (also referred to as a mode transition operation, which will be described in detail later) for switching the operation mode by a clerk. The operation mode of the POS terminal 20 may be switched according to another operation different from the mode switching operation (for example, reading a clerk code).

  The operation mode of the POS terminal 20 may be switched regardless of the operation of the clerk. Specifically, the operation mode of the POS terminal 20 may be switched according to a mode switching command (mode switching instruction) from another terminal (the POS terminal 20, the monitoring terminal, the mobile terminal, or the like). The operation mode of the POS terminal 20 may be switched according to a temporal condition (for example, an elapsed time since the last operation, a scheduled time, or the like). The operation mode of the POS terminal 20 may be switched at the start of the processing (for example, at the start of the payment processing based on the received registration information, at the start of the payment processing based on the bill). Further, the POS terminal 20 may be configured to switch the operation mode at the end of the processing (for example, at the end of the payment processing based on the received registration information, at the end of the payment processing based on the bill).

  FIG. 6 is a diagram illustrating switching of the operation mode of the POS terminal 20. The left side of FIG. 6 shows a combination of operation modes before and after switching (operation mode before switching → operation mode after switching), and the right side shows conditions (one example) for switching operation modes. For example, the row a indicates, as an example of the condition for switching the operation mode from the normal mode to the full self mode, a mode switching operation, a mode switching command, and a lapse of a predetermined time (unused). In other words, when the operation mode is the normal mode, for example, when there is a mode switching operation, a mode switching command, a lapse of a predetermined time (unused), or the like, the operation mode is switched from the normal mode to the full self mode. Is shown. The details of the mode switching operation will be described later.

(Normal mode → Full self mode)
As shown in a, when the normal mode is set, for example, a mode switching operation, a mode switching command (a mode switching command in which the full self mode is specified as the transition destination operation mode, etc.), a predetermined time elapses (for a predetermined time, If not, the operation mode switches from the normal mode to the full self mode.

(Normal mode → Semi-self mode (accounting only mode))
As shown in b, in the normal mode, for example, there are a mode switching operation, a mode switching command (a mode switching command in which the semi-self mode (accounting-only mode) is specified as the transition destination operation mode, and the like). In this case, the operation mode switches from the normal mode to the semi-self mode (accounting-only mode). In the normal mode, the operation mode may be switched from the normal mode to the semi-self mode (accounting-only mode) when, for example, receiving registration information from another terminal or reading a voucher. .

(Full self mode → Normal mode)
As shown in c, when the mode is the full self mode, for example, when there is a mode switching operation, a mode switching command (a mode switching command specifying the normal mode as the transition destination operation mode), and the like, The operation mode switches from the full self mode to the normal mode.

(Full self mode → semi self mode (accounting only mode))
As shown in d, when the mode is the full self mode, for example, a mode switching operation, a mode switching command (a mode switching command specifying a semi-self mode (accounting-only mode) as a transition destination operation mode, etc.) and the like are given. In this case, the operation mode switches from the full self mode to the semi self mode (accounting only mode). Also, in the full self mode, for example, when the registration information is received from another terminal or when the bill is read, the operation mode is switched from the full self mode to the semi self mode (accounting only mode). Is also good.

(Full self mode → Double scan mode)
As shown in e, when the clerk code is read in the full self mode, for example, the operation mode is switched from the full self mode to the double scan mode. Note that the double scan mode is one mode of the full self mode (a state in which the function of merchandise registration (clerk side) is used in addition to the function of merchandise registration (customer side); see FIG. 5A).

  If a clerk code is read while in the full self mode, the operation mode may always be switched to the double scan mode regardless of the product registration state, or the product registration state may be changed. The operation mode may be switched to a different operation mode in response. For example, if the salesclerk code is read while the product has not been registered yet (that is, if the product has not been registered by the customer), the mode is switched from the full self mode to the normal mode, If the clerk code is read while the product is being registered (that is, while the customer is registering the product), the mode may be switched from the full self mode to the double scan mode. Good.

(Semi-self mode (accounting only mode) → normal mode)
As shown in f, when in the semi-self mode (accounting-only mode), for example, there is a mode switching operation, a mode switching command (a mode switching command in which the normal mode is specified as the operation mode of the transition destination), and the like. In this case, the operation mode switches from the semi-self mode (accounting-only mode) to the normal mode. In the semi-self mode (accounting-only mode), for example, when the settlement process (eg, the settlement process based on the received registration information, the settlement process based on the bill) is completed, the semi-self mode (the accounting-only mode) is used. ) May be switched to the normal mode.

(Semi-self mode (accounting only mode) → full self mode)
As shown in g, when in the semi-self mode (accounting-only mode), for example, there is a mode switching operation, a mode switching command (a mode switching command in which the full self mode is specified as the transition destination operation mode, etc.), and the like. In this case, the operation mode is switched from the semi-self mode (accounting-only mode) to the full self mode. In the semi-self mode (accounting-only mode), for example, when the settlement process (eg, the settlement process based on the received registration information, the settlement process based on the bill) is completed, the semi-self mode (the accounting-only mode) is used. ) May be switched to the full self mode.

  The mode switching operation may be any operation as long as the operation mode of the transition destination is specified according to the operation. For example, when each button is provided (or displayed) for each destination, the operation mode may be switched to each destination according to a mode switching operation of pressing each button. In the case where a single button is provided (or displayed) for switching the destination each time the button is pressed, the operation mode may be switched for each mode switching operation in which the button is pressed.

  Note that a button for selecting the operation mode of the transition destination and a button for determining transition to the operation mode selected by the button may be separately provided (or displayed).

(Transition of operation mode by mode switching operation)
Subsequently, the transition of the operation mode by the mode switching operation will be described. The operation mode of the POS terminal 20 is switched according to an explicit mode switching operation by a clerk (see FIG. 6). 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.

(Operation of each operation mode)
FIG. 7 is a schematic diagram for explaining the outline of the operation in the normal mode. Specifically, FIG. 7 is a schematic diagram illustrating a flow of processing and an operation of a person (a clerk or a customer) when executing the payment processing in the own terminal in the normal mode. FIG. 8 is a flowchart illustrating an outline of the operation in the normal mode. Specifically, FIG. 8 is a flowchart illustrating an outline of an operation in a case where the terminal performs the settlement process in the normal mode.

  In the normal mode (the same applies to the case where the payment process is executed on the own terminal and the case where the other terminal executes the payment process), the clerk can display the purchased product of the customer on the clerk side (the clerk side scanner section 212, the clerk side display section 210, It is registered by the key operation unit 211) (the upper part of FIG. 7). That is, the POS terminal 20 executes the registration processing 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) (the upper part of FIG. 7). ).

  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. 7). That is, the POS terminal 20 executes the settlement process by a customer operation or the like (putting cash into the change machine 209, operating the card settlement unit 208) (the lower part of FIG. 7).

  That is, when the settlement process is executed in the own terminal in the normal mode, as shown in FIG. 8, first, the merchandise is scanned on the clerk side (step S10: YES), and the merchandise is registered (step S11). After pressing a subtotal key (for example, a subtotal key displayed on the clerk side display unit 210 or a subtotal key arranged on the key operation unit 211) (step S30: YES), the customer side, for example, the change machine 209 (Step S50), and the process is completed. The subtotal key in step S30 is an operation key for completing the registration process, and may be referred to as a subtotal button, a registration completion key, a registration completion button, 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 (upper row in FIG. 7).

  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.

  The clerk may be on standby 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 checkout process (the lower part of FIG. 7). Also, the clerk may be absent during the checkout by the customer (lower part in FIG. 7). That is, during the checkout of the customer, the reception of the customer may be ended.

  In addition, when there is change, the POS terminal 20 controls the dispensing of change and bills by the change machine 209 in order to prevent forgetting to 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.

  FIG. 9 is a schematic diagram for explaining the outline of the operation in the normal mode. Specifically, FIG. 9 is a schematic diagram illustrating a flow of processing and an operation of a person (a clerk or a customer) in a case where another terminal performs the payment processing in the normal mode (standard mode). FIG. 10 is a flowchart illustrating an outline of the operation in the normal mode and the like. Specifically, FIG. 10A is a flowchart illustrating an outline of an operation in a case where another terminal performs the settlement process in the normal mode (standard mode). FIG. 10B is a flowchart showing a basic flow of an operation in another terminal (another device) in FIG. 10A.

  In the normal mode (the same applies to the case where the payment process is executed on the own terminal and the case where the other terminal executes the payment process), the clerk can display the purchased product of the customer on the clerk side (the clerk side scanner section 212, the clerk side display section 210, It is registered by the key operation unit 211) (the upper part of FIG. 9). That is, the POS terminal 20 (the POS terminal 20-1 in the example of FIG. 9) performs the registration processing of the purchased product by the operation of the clerk (operation of the clerk-side scanner unit 212, the clerk-side display unit 210, the key operation unit 211, and the like). (The upper part of FIG. 9).

  When the registration process by the clerk is completed, the customer moves to another POS terminal 20 (POS terminal 20-2 in the example of FIG. 9), checks the total price of the purchased product on the clerk side display unit 210, Money is input to 209 or the card settlement unit 208 is operated to settle the money (lower row in FIG. 9). In other words, the other POS terminal 20 executes the settlement process by a customer operation or the like (insertion of money into the change machine 209, operation of the card settlement unit 208) (the lower part of FIG. 9).

  Note that the other POS terminal 20 (POS terminal 20-2) is supplied with information necessary for the settlement process (such as registration information generated in the POS terminal 20-1).

  In addition, the clerk designates the POS terminal 20 (one of the POS terminal 20-2 and the POS terminal 20-3 in the example of FIG. 9) for executing the settlement process in the POS terminal 20-1. Alternatively, the clerk causes the POS terminal 20-1 to issue a medium (check certificate) to be read by the POS terminal 20 (the POS terminal 20-2 or the POS terminal 20-3 in the example of FIG. 9) for executing the settlement process. You may.

  That is, when the other terminal performs the settlement process in the normal mode, as shown in FIG. 10A, 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), for example, the settlement process is executed. Is designated (step S31: YES), the registration information is transmitted to the designated POS terminal 20 (step S32), and the process on the registration side is completed.

  Note that the clerk can register the purchased product of the next customer after designating another terminal (the lower part of FIG. 9). Also, the clerk may be absent after specifying another terminal (lower part in FIG. 9).

  Also, in the example shown in FIG. 10A, another POS terminal 20 is specified after the subtotal key is pressed, but another POS terminal 20 may be specified without pressing the subtotal key. . For example, a subtotal key and a key for designating another POS terminal 20 are arranged on the registration screen (a key for issuing a voucher may also be arranged), and the POS terminal 20 is designated. When the key is pressed, the registration information may be transmitted. In a mode in which another POS terminal 20 is specified without pressing the subtotal key, it is not necessary to press the subtotal key after pressing the key for specifying another POS terminal 20.

  Although omitted in the example shown in FIG. 10 (A), a bill may be issued to be read by another POS terminal 20, and the other POS terminal 20 may execute the settlement process. Note that the key for issuing a check voucher may be pressed after the subtotal key is pressed, or may be pressed before the subtotal key is pressed. In a mode in which the key for issuing the check is pressed before the subtotal key is pressed, it is not necessary to press the subtotal key after pressing the key for issuing the check.

  The other POS terminal 20 that has received the registration information (POS terminal 20-2 in the example of FIG. 9) receives the registration information (step S40: YES) as shown in FIG. If it is not (accounting only mode), it shifts to (switches) to the semi-self mode (accounting only mode). That is, if the current operation mode (when the registration information is received) is the full self mode (step S41: YES), the mode shifts from the full self mode to the semi self mode (accounting only mode) (step S42), and the current operation mode is set. Is in the normal mode (step S43: YES), the mode shifts from the normal mode to the semi-self mode (accounting-only mode) (step S42). Then, on the customer side, the settlement is performed by, for example, the change machine 209 (step S50), and the processing on the settlement side is completed.

  In the example shown in FIG. 10B, after receiving the registration information, the other POS terminals 20 shift to the semi-self mode (accounting-only mode) if they are not in the semi-self mode (accounting-only mode). However, it is not necessary to shift to the semi-self mode (accounting only mode). In other words, since the settlement process can be performed in the normal mode or the full self mode (see FIG. 5), the settlement process may be executed in the normal mode or the full self mode.

  As described above, the normal mode (standard mode) is a function in which the clerk executes the registration process and then executes the checkout process on the customer side of the terminal using the registration information generated in the registration process (FIG. 7). , FIG. 8), and a function of transmitting 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) to cause the other terminal to execute the settlement process. (See FIG. 9 and FIG. 10) and issue a bill of coupon printed by converting the registration information (or information for acquiring the registration information) generated in the registration process into a code (barcode, two-dimensional code, etc.) And causing the other terminal to execute a settlement process.

  On the other hand, in the normal mode (restricted mode), as shown in FIG. 5B, among the functions of the normal mode (standard mode) described above, the registration information generated in the registration process is transmitted to another terminal and other functions are transmitted. A function for causing the terminal to execute the settlement process, and issuing a bill printed by coding and printing the registration information (or information for acquiring the registration information) generated in the registration process to execute the settlement process on the other terminal. In this mode, the functions to be executed are restricted.

  Further, among the functions of the normal mode (standard mode) described above, a function of transmitting the registration information generated in the registration process to another terminal to cause the other terminal to execute a settlement process, and a function of transmitting the registration information generated in the registration process ( Alternatively, the function of issuing a cash voucher by encoding and printing the information for acquiring the registration information and causing the other terminal to execute the settlement process is also a function of a semi-self mode (registration only mode). In other words, the semi-self mode can be classified into a registration-only mode and an accounting-only mode. As shown in FIG. 5B, the semi-self mode (registration-only mode) adds registration information generated in the registration process to another. A function to transmit to the terminal to cause the other terminal to execute the settlement process, and to issue a bill issued by encoding and printing the registration information generated in the registration process (or information for acquiring the registration information). And a function of causing the other terminal to execute a settlement process. In other words, the semi-self mode (registration-only mode) is a function of the terminal that uses the registration information generated in the registration process after the clerk performs the registration process among the functions of the normal mode (standard mode) described above. This is a mode in which the function of executing the payment process on the customer side is restricted. That is, the semi-self mode (registration only mode) is an operation mode in which the registration process is exclusively performed.

  The semi-self mode (accounting-only mode) is, as shown in FIG. 5A, a function of receiving registration information generated in the registration processing of another terminal and executing a settlement process, and a function issued by the other terminal. Includes the function of reading bills and executing settlement processing. That is, the semi-self mode (accounting-only mode) is an operation mode in which the settlement process is executed exclusively.

  FIG. 11 is a schematic diagram for explaining the outline of the operation in the full self mode. FIG. 12 is a flowchart illustrating an outline of the operation in the full self mode.

  In the full self mode, the customer registers his or her purchased merchandise on the customer side (customer-side scanner unit 206, customer-side display unit 205) (upper row in FIG. 11). 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. 11).

  When the registration process is completed, the customer checks the total price of the purchased merchandise on the customer-side display unit 205 and puts cash into the change machine 209 or operates the card settlement unit 208 to settle the payment (lower part in FIG. 11). ). That is, 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. 11).

  That is, in the case of the full self mode, as shown in FIG. 12, 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.

  Note that in the full self mode, as shown in FIG. 11, the customer performs both the registration processing and the settlement processing, but this does not mean that the clerk cannot do anything. That is, even when the POS terminal 20 is operating in the full self mode, for example, the clerk scans a product on the clerk side (double scan mode) and displays various information on the clerk side. It is possible.

  FIG. 13 is a schematic diagram for explaining the outline of the operation in the double scan mode. FIG. 14 is a flowchart illustrating an outline of the operation in the double scan mode. Note that the double scan mode is one mode of the full self mode, but in FIGS. 13 and 14, the two operation modes will be described separately for convenience.

  In the full self mode, the customer registers his or her purchased merchandise on the customer side (upper row in FIG. 11 and upper row in FIG. 13). That is, the POS terminal 20 executes the registration processing of the purchased product by the operation of the customer (upper part in FIG. 11, (upper part in FIG. 13)).

  During the registration process by the customer, the clerk registers the purchased product of the customer at the clerk side (middle of FIG. 13). That is, the POS terminal 20 executes a registration process by a customer's operation and a registration process by a clerk's operation (middle of FIG. 13).

  When the registration process is completed, the customer checks the total price of the purchased merchandise on the customer-side display unit 205, puts cash into the change machine 209, or operates the card settlement unit 208 to make a payment (lower part in FIG. 13). ). In other words, the POS terminal 20 executes the settlement process by a customer operation or the like (putting cash into the change machine 209, operating the card settlement unit 208) (lower part in FIG. 13).

  That is, when the registration process is being executed in the full self mode (see FIG. 12), as shown in FIG. 14A, when the clerk code is read by the clerk-side scanner unit 212 (step S110: YES). Then, the operation mode shifts from the full self mode to the double scan mode (step S111).

  After shifting to the double scan mode, as shown in FIG. 14B, the merchandise is registered (step S11) by scanning the clerk-side scanner unit 212 (step S10: YES), and the customer-side scanner unit 206 is scanned. The product is registered by scanning or the like (step S20: YES) (step S21). A subtotal key (for example, a subtotal key displayed on the clerk side display unit 210 or a subtotal key arranged on the key operation unit 211) or a registration completion key (for example, a registration displayed on the customer side display unit 205) After the completion key is pressed (step S41: YES), settlement is performed on the customer side by, for example, the change machine 209 (step S50), and the process is completed.

  In the double scan mode, the clerk may wait until the customer completes the payment (until the customer takes a change or a receipt), or may register the next customer's purchased product. In other words, the POS terminal 20 can register the purchased product of the next customer during the settlement process (lower part in FIG. 13). Further, the clerk may be absent during the checkout by the customer (lower part in FIG. 13). That is, during the checkout of the customer, the reception of the customer may be ended.

  As shown in FIG. 14A, when the clerk code is read in the full self mode, the operation mode shifts from the full self mode to the double scan mode. It may be one. Further, when another operation (for example, a login operation different from the reading of the clerk code) is performed in the full self mode, the operation mode may shift from the full self mode to the double scan mode. Further, when the operation by the clerk is not performed in the double scan mode (for example, when a predetermined time has elapsed from the time of the last operation), the operation mode may shift from the double scan mode to the full self mode.

(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. May be. 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, when operating in the two operation modes of the normal mode and the full self mode, the normal mode image and the full self mode image are always displayed, and the normal mode image is displayed when the current operation mode of the own terminal is the normal mode. The display may be performed in a display mode that is more prominent than the full self mode image, and when the current operation mode of the own terminal is the full self mode, the full self mode image may be displayed in a display mode that is more prominent 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 the own terminal. That is, the POS terminals 20 may notify 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 the monitoring terminal). Further, each POS terminal 20 may report 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 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 terminal is in a standby state, the POS terminal 20 may display various types of information on the customer-side display unit 205. 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.

  Even when the operation mode is switched by the operation of the clerk (by the mode switching operation, the reading of the clerk code, or the like), the operation mode is switched without the operation of the clerk (mode switching instruction, predetermined time). Even if it is due to elapse, etc.), the operation mode of the own terminal or another terminal is notified.

(Storage of information on operation mode)
Each POS terminal 20 may store in which operation mode the transaction (processing) was performed, as information on the operation mode. For example, when the POS terminal 20-1 operating in the normal mode (standard mode) executes a registration process and a payment process for a certain transaction, the POS terminal 20-1 that has performed the registration process and the payment process executes the transaction. As information (for example, settlement information) (or in association with information about the transaction), information indicating that the registration processing and the settlement processing for the transaction have been performed in the normal mode (standard mode) (for example, identifying the operation mode). Possible information) may be stored.

  Note that each POS terminal 20 may also store the transaction (process) at which terminal. In the above example, the POS terminal 20-1 may store, as the information regarding the transaction, information indicating that the registration process and the settlement process have been performed in the own terminal (POS terminal 20-1). More specifically, the POS terminal 20-1 stores the terminal identification information of its own terminal as the identification information (terminal identification information) of the terminal that has performed the registration processing, and has its own terminal identification information of the terminal that has performed the settlement processing. The terminal identification information of the terminal may be stored. Alternatively, the POS terminal 20-1 may store the terminal identification information of its own terminal as the terminal identification information of the terminal that has performed the entire process (registration processing, settlement processing).

  Also, for example, first, the POS terminal 20-1 operating in the normal mode (standard mode) executes a registration process for a certain transaction, and then, the POS terminal 20-2 operating in the semi-self mode (accounting-only mode). However, when the settlement process is performed on the transaction based on the registration information obtained by the registration process, the POS terminal 20-2 that has performed the settlement process determines that the information regarding the transaction (for example, the settlement information) (or the payment information). (Corresponding to information related to the transaction), and stores information indicating that the registration process related to the transaction was performed in the normal mode (standard mode), and that the settlement process related to the transaction was performed in the semi-self mode (accounting-only mode). Information may be stored. In addition, in addition to the above, the POS terminal 20-1 that has performed the registration process may store information indicating that the registration process regarding the transaction has been performed in the normal mode (standard mode).

  In the above example, the POS terminal 20-2 that has executed the settlement process stores information indicating that the registration process has been executed in the other terminal (POS terminal 20-1) as information relating to the transaction, and stores the information in the own terminal (POS terminal). Information indicating that the settlement process has been executed in the terminal 20-2) may be stored. More specifically, the POS terminal 20-2 stores the terminal identification information of the other terminal (POS terminal 20-1) as the information (terminal identification information) of the terminal that has performed the registration processing, and the terminal that has performed the settlement processing. The terminal identification information of the own terminal (POS terminal 20-2) may be stored as the terminal identification information. In the above example, the terminal identification information and the operation mode (specifically, the normal mode (standard mode)) of the POS terminal 20-1 that has performed the registration processing are displayed on the side of the POS terminal 20-2 that executes the payment processing. It is only necessary that information to identify can be obtained. For example, the terminal identification information of the POS terminal 20-1 and the information for identifying the operation mode are supplied from the POS terminal 20-1 to the POS terminal 20-2 (for example, transmission and reception as registration information, Supply).

  In addition, each POS terminal 20 may store the transition (switch) of the operation mode as the information on the operation mode. For example, when the operation mode of the POS terminal 20-1 shifts from one operation mode to another operation mode, which operation mode the POS terminal 20-1 shifts to along with the operation mode shift time. (For example, information for identifying the operation mode after the shift) may be stored. In addition, the POS terminal 20-1 includes, in addition to the operation mode transition time, information indicating which operation mode has transitioned to which operation mode (for example, information that can identify the operation mode before transition, operation mode after transition). May be stored.

  In addition, even when the operation mode is switched by the operation of the clerk (by the mode switching operation, the reading of the clerk code, or the like), the operation mode of each POS terminal 20 is changed without the operation of the clerk ( (In the case of a mode switching command, the lapse of a predetermined time, etc.), information on the transition of the operation mode may be stored. In the above case, each POS terminal 20 has information on what the operation mode has been shifted to (for example, the fact that the operation mode has been shifted by the operation of the clerk with the clerk code “xxx”, and the terminal identification information “xx”. The operation mode may be changed in response to a mode switching command from the POS terminal 20 of “×”).

  Note that, instead of or in addition to the POS terminal 20, the store controller 10, the monitoring terminal, or the like may store information regarding the operation mode.

  Further, the information on the operation mode stored as described above may be output (displayed, transmitted, printed, etc.) as necessary. For example, the POS terminal 20 includes, in the receipt output in the full self mode, information indicating that processing (registration processing, settlement processing) has been performed in the full self mode (information in a form that only a store clerk can recognize the contents, or May also be printed. Receipts output in other operation modes may be printed in the same manner. Further, for example, the POS terminal 20 (or the monitoring terminal) may display an operation mode at the time of processing. As an example, when a transaction number (information capable of identifying a transaction) is input to a predetermined search screen or the like, the POS terminal 20 (or the monitoring terminal) performs a registration process and a payment process for the corresponding transaction. For at least one, the processed terminal (terminal identification information or the like) and the operation mode (information that can identify the operation mode) may be displayed.

  In the following description, it is assumed that the POS terminal 20-1 and the POS terminal 20-2 are in a normal mode (specifically, a normal mode (standard mode)). It is assumed that the POS terminal 20-3 is in the full self mode.

(Display example of POS terminal 20 in full self mode)
15 and 16 show display examples on the POS terminal 20 in the full self mode. Specifically, FIG. 15A, FIG. 15B, and FIGS. 16A to 16F each show a table on the customer side display unit 205 of the POS terminal 20-3 in the full self mode. This is an example.

  FIG. 15A shows the display contents of the registration start screen before the start of the registration processing. In FIG. 15A, a registration start button BT30 on the right side of the screen is a button for instructing the start of product registration. The customer operates the registration start button BT30 when starting 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. 15B shows the display contents of the registration screen in a state where two items of goods (daifuku mochi) are registered. Note that when the registration start button BT30 is operated on the registration start screen shown in FIG. 15A, the POS terminal 20-3 displays a registration screen in which no product has been registered yet. FIG. 15B shows a registration screen after a product (tea, Daifuku mochi) has already been registered for convenience.

  In FIG. 15B, an image GA01 at the lower left of the screen indicates a state of the other terminal (POS terminal 20-1) (specifically, the normal mode). The image GA02 at the lower left of the screen shows the state of the other terminal (POS terminal 20-2) (specifically, the normal mode). The checkout button BT32 at the lower right of the screen is a button for instructing the end of product registration. The customer operates the checkout button BT32 after completing the product registration. The clerk call button BT33 is a button for calling a clerk. The customer operates the clerk call button BT33 when calling the clerk (for example, when the clerk needs support).

  The buttons BT35 to BT37 are buttons for switching the display language to English, Chinese, and Korean, respectively, as described above. The “vegetables” button BT38 is a button for displaying each vegetable preset key (see FIG. 17).

  FIG. 16A shows the contents of a payment screen (payment method selection screen) displayed when the payment processing is started. For example, when the checkout button BT32 is operated on the registration screen (see FIG. 15B), the POS terminal 20-3 displays a payment method selection screen as shown in FIG. 16A.

  FIG. 16 (B) shows the display contents of a settlement screen (payment screen) displayed when the cash payment is started. For example, when cash is operated on the payment method selection screen (see FIG. 16A), the POS terminal 20-3 displays a payment screen as shown in FIG. 16B.

  FIG. 16C shows the display contents of a settlement screen (payment screen) displayed when the deposit amount is determined. For example, when cash (deposit) equal to or more than the payment amount (purchase amount) is inserted, the POS terminal 20-3 displays a payment screen as shown in FIG. 16C.

  FIG. 16D shows the display contents of the settlement screen (change screen) displayed when the change is released. For example, when the end (receipt) button BT40 is operated on the payment screen (FIG. 16C), the POS terminal 20-3 displays a change screen as shown in FIG. 16D.

  FIG. 16E shows the display contents of the settlement screen (receipt screen) displayed when the change is removed. For example, when the change is removed from the outlet of the change machine 209, the POS terminal 20-3 displays a receipt screen as shown in FIG. Note that the POS terminal 20 may be provided with a sensor such as a photo sensor near the take-out port, and when the sensor recognizes an object (assuming a customer's hand), it may be determined that the change has been removed. FIG. 16F shows a sleep screen displayed in the sleep mode (sleep state).

  After the receipt screen (FIG. 16E) is displayed, the POS terminal 20-3 displays the registration start screen (FIG. 15A). For example, the POS terminal 20-3 displays the registration start screen after the receipt is removed from the issuing port of the printing unit 213. The POS terminal 20 may include a sensor that can recognize that the receipt has been removed from the issuing port. If no change is generated, the change screen (FIG. 16 (C)) may be changed to the receipt screen (FIG. 16 (E)) without displaying the change screen (FIG. 16 (D)). .

(Display example of POS terminal 20 in normal mode)
17 to 22 show display examples on the POS terminal 20 in the normal mode. More specifically, FIG. 17A, FIG. 18A, FIG. 19A, FIG. 20A, FIG. 21A, and FIG. 3) is a display example on the clerk side display unit 210 of the POS terminal 20-1. FIGS. 17 (B), 18 (B), 19 (B), 20 (B), 21 (B), and 22 (B) show the POS terminal 20 in the normal mode (standard mode). 6 is a display example on the customer side display unit 205 of -1.

  FIG. 17A 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. 17A, a tab area T1 at the upper right of the screen is a tab corresponding to each display content (display screen). The 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 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. 17A, the number of tabs is one (tab area T1), but the POS terminal 20-1 displays a number of tabs according to the number of registered screens (the number of customers) in progress (tabs). The registration screen to be activated (activated) is switched according to the operation (pressing) of the area T1, T2, T3,...) And tab.

  In the tab area T1, information for identifying the tab from other tabs (the number “1” in the example of FIG. 17A) is displayed. Further, in the tab area T1, a display field HR01 for displaying a deposit amount from a customer is provided. Although not displayed in the example shown in FIG. 17A, 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 (POS terminal 20-2) (specifically, the normal mode). Image GA03 at the lower left of the screen shows the state of the other terminal (POS terminal 20-3) (specifically, the full self mode).

  FIG. 17B shows display contents on the customer side display unit 205 in an initial state. That is, when the POS terminal 20-1 displays the registration screen on the clerk-side display unit 210 as shown in FIG. 17A, the POS terminal 20-1 displays on the customer-side display unit 205 as shown in FIG. A small screen (small window) SG01 is superimposed and displayed on the settlement screen (payment screen).

  The small screen SG01 allows the customer to select a payment method. The customer selects one of cash, credit, and electronic money as a payment method on the small screen SG01. When the customer desires cash as the payment method, the customer may put cash (deposit) before selecting cash as the payment method on the small screen SG01. The POS terminal 20-1 deletes the small screen SG01 when any payment method is selected on the small screen SG01. When cash is input before the payment method is selected on the small screen SG01, the POS terminal 20-1 processes the cash as the payment method is selected, and deletes the small screen SG01.

  The POS terminal 20-1 displays the registration screen of FIG. 17A on the clerk-side display unit 210 and, when canned beer is registered by the clerk, displays the registration screen of FIG. 18A on the clerk-side display unit 210. The registration screen as shown in is displayed.

  In FIG. 18A, 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.

  The 20-2 cash register button BT12 is a button for designating a 20-2 cash register (POS terminal 20-2). The clerk operates the 20-2 cashier button BT12 when designating the POS terminal 20-2 as the terminal transmitting the registration information. “(Normal)” indicated on the 20-2 cashier button BT12 indicates that the operation mode of the 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 (POS terminal 20-3). The clerk operates the 20-3 cashier button BT13 when designating the POS terminal 20-3 as the terminal transmitting the registration information. “(Full self)” indicated on the 20-3 cash register button BT13 indicates that the operation mode of the POS terminal 20-3 corresponding to the 20-3 cash register button BT13 is the full self mode.

  The check voucher button BT15 is a button for causing the print unit 213 to issue a check voucher. The clerk operates the bill ticket button BT15 when the POS terminal 20 that has read the bill (the POS terminal 20 from which the customer has read the bill) 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 FIGS. 7 and 8), processing (for example, registration processing, customer correspondence, etc.) continues to exist 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. 18A, the outline of the 20-3 cashier button BT13 corresponding to the 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. The outline of the 20-2 register button BT12 corresponding to the POS terminal 20-2 in the normal mode, which is relatively unfavorable, is indicated by a broken line. 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).

  When the POS terminal 20-1 displays the registration screen as shown in FIG. 18A on the clerk-side display unit 210, the POS terminal 20-1 displays a small screen as shown in FIG. The screen SG01 is superimposed and displayed on the settlement screen (payment screen). The total amount was 0 yen on the settlement screen (payment screen) in FIG. 17B because no merchandise was registered, but in the settlement screen (payment screen) in FIG. Is registered, the total amount is 215.

  The POS terminal 20-1 displays the registration screen of FIG. 18A on the clerk-side display unit 210 and, when 500 yen is inserted by the customer, displays the registration screen of FIG. The registration screen as shown in is displayed.

  Since the customer has inserted 500 yen, 500 is displayed in the display field HR01 in the upper right of the screen in FIG. 19 (A). In addition, since the payment is made at the own terminal (POS terminal 20-1) by inserting 500 yen, it is used when the payment is made at another terminal (POS terminal 20-2, POS terminal 20-3). Buttons (20-2 cash register button BT12, 20-3 cash register button BT13, check ticket button BT15) are not displayed (erased).

  When the POS terminal 20-1 displays the registration screen as shown in FIG. 19A on the clerk side display unit 210, the POS terminal 20-1 displays the settlement screen (payment screen) as shown in FIG. 19B. It is displayed on the customer side display unit 205. Since 500 yen has been inserted by the customer, the small screen SG01 has been deleted.

  In the POS terminal 20-1, two items (asparagus) and three items (paste lunch) are registered by the clerk from the state where the registration screen of FIG. 19A is displayed on the clerk side display unit 210. When the customer has further inserted 500 yen, a registration screen as shown in FIG. Since the customer has inserted 500 yen, 1000 is displayed in the display field HR01 in the upper right of the screen in FIG.

  When the POS terminal 20-1 displays the registration screen as shown in FIG. 20A on the clerk side display unit 210, the POS terminal 20-1 displays the settlement screen (payment screen) as shown in FIG. It is displayed on the customer side display unit 205.

  When the clerk operates the subtotal button BT10 from the state in which the registration screen of FIG. 20A is displayed on the clerk-side display unit 210, the POS terminal 20-1 displays the registration screen of FIG. ), The small screen (small window) SG02 is displayed so as to be superimposed on the registration screen, and a checkout screen (payment 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)).

  When the customer operates the end (receipt) button BT40 from the state in which the payment screen (payment screen) shown in FIG. 21B is displayed on the customer side display unit 205, the POS terminal 20-1 displays the clerk side. In the section 210, the message screen MG1 is superimposed on the registration screen as shown in FIG. 22A and displayed, and the checkout screen (change screen) as shown in FIG. indicate.

  Message screen MG1 is for notifying the clerk of the change. The POS terminal 20-1 deletes the message screen MG1 superimposed on the registration screen and displayed without being operated by the clerk (for example, automatically after a predetermined time has elapsed). Note that the POS terminal 20-1 may delete the message screen MG1 displayed superimposed on the registration screen in accordance with an operation of the clerk (such as a touch on the message screen MG1).

  Although illustration is omitted in FIG. 22 and subsequent figures, the POS terminal 20-1 displays a payment screen similar to that shown in FIG. 16 (E) and later on the customer-side display unit 205, and displays a payment screen on the clerk-side display unit 210. Display the corresponding message.

  In the above description, attention is paid to the overall processing in the POS terminal 20, and no processing is in progress (commodity not registered, cash not inserted, payment type not selected, gift certificate not registered, customer information not acquired Is referred to as the initial state, but the processing may be referred to as an initial state by focusing on a part of the processing. For example, the cash input product registration state (product registration, cash input, payment type not selected, gift certificate unregistered, customer information not obtained) can be said to be an initial state when focusing on the entire processing. However, if attention is paid only to the state of selection of the settlement type, it may be said that this is the initial state. In addition, when focusing on two states, ie, a state of registering a product and a state of selecting a payment type, the state cannot be said to be an initial state. However, two states of a state of selecting a payment type and a state of registering gift certificates are considered. When attention is paid to, it may be said that this is the initial state.

  In the example shown in FIG. 21, the POS terminal 20-1 displays the small screen SG02 superimposed on the registration screen when the subtotal key is operated (FIG. 21A). When the subtotal key is operated, terminal 20-1 may display a small planning surface for displaying information or the like displayed on small screen SG02, instead of (switching) the registration screen.

(About advertisement display in full self mode)
Next, an outline of advertisement display in the full self mode will be described. FIG. 23 is an explanatory diagram showing an outline of advertisement display in the full self mode.

(About the layout of the POS terminal 20)
First, the layout of the POS terminal 20 will be described. As shown in FIG. 23, for example, in a store such as a supermarket, four POS terminals 20 (20-A, 20-B, 20-C, 20-D) are arranged in two rows (two lanes) of two POS terminals 20 each. Are located. The two lanes are formed so as to be substantially parallel, for example. In a region sandwiched between the lanes, a clerk region 300 where a clerk can enter is formed. Of the four POS terminals 20, the POS terminal 20-A and the POS terminal 20-C are arranged to face each other (facing). Further, the POS terminal 20-B and the POS terminal 20-D are arranged to face each other (facing).

  For this reason, the POS terminal 20-A and the POS terminal 20-C are arranged so that the clerk-side display units 210 face each other. Similarly, the POS terminal 20-B and the POS terminal 20-D are arranged so that the clerk-side display units 210 face each other. In the following description, a configuration (POS system 1) including the four POS terminals 20 illustrated in FIG. 23 may be referred to as an “island”.

  Here, two facing POS terminals 20 will be described. Hereinafter, the POS terminals 20-A and 20-C will be described as an example of the two POS terminals 20, but the same applies to the POS terminals 20-B and 20-D. Further, each POS terminal 20 has the same function and can perform the same operation. Specifically, the POS terminal 20-C can perform the same operation as the operation performed by the POS terminal 20-A, and the POS terminal 20-A performs the same operation as the operation performed by the POS terminal 20-C. It is possible to do.

  As shown in FIG. 23, the POS terminals 20 (POS terminals 20-A, 20-C) are arranged facing each other, and more specifically, are arranged on a straight line in the horizontal direction in the figure. However, the POS terminals 20 need not be arranged in a straight line in the horizontal direction in the figure. For example, the entire right column (the lane including the POS terminal 20-B) in which the POS terminals 20-A are arranged is arranged upward in the drawing, and the entire left column (the lane including the POS terminals 20-C) is arranged ( (The lane including the POS terminal 20-D) may be arranged in the downward direction in the figure.

(About the mode of the POS terminal 20)
Next, each mode of the four POS terminals 20 will be described. At the time of congestion, the POS terminals 20-A and 20-C enter the normal mode, and the POS terminals 20-B and 20-D enter the semi-self mode (accounting-only mode). In the normal mode, a clerk stands in the clerk area 300 of each of the POS terminals 20-A and 20-C, and the clerk registers the product. For this reason, a space where at least two clerks enter (in a row) is secured in the clerk area 300.

  When a product is registered in the POS terminal 20-A (or the POS terminal 20-C) in the normal mode, the POS terminal 20-A (or the POS terminal 20-C) in the normal mode is changed from the POS terminal 20-C in the accounting-only mode. The registration information is transmitted to B (or the POS terminal 20-D). For this reason, the POS terminal 20 on the upstream side (POS terminals 20-A, 20-C) can register and settle the merchandise, and can store the POS terminal 20 on the downstream side (POS terminals 20-B, 20-C). In -D), payment can be performed.

  Here, the cause of congestion is that the customer takes time to settle. However, by setting the POS terminal 20 on the upstream side to the normal mode and the POS terminal 20 on the downstream side to the semi-self mode, a plurality of customers are required. , The payment process can be performed simultaneously and in parallel. As a result, it is possible to shorten the time required for the settlement process when a plurality of customers perform the settlement, thereby suppressing the queue of customers waiting for the registration or settlement of the product (occurrence of traffic jams) and reducing congestion. be able to.

  Next, the full self mode will be described. The full self mode is a mode set when there is no congestion. In FIG. 23, all four POS terminals 20 are set to the full self mode. In the full self mode, in principle, product registration using the clerk-side display unit 210 is not performed, so the frequency of using (operating) the clerk-side display unit 210 is lower than in the case where the normal mode is set. Therefore, in the present embodiment, predetermined information is displayed on the clerk-side display unit 210 according to the set mode, so that the clerk-side display unit 210 is effectively used.

  More specifically, in the full self mode, the POS terminal 20 displays different information on the clerk side display unit 210 depending on whether the clerk exists in the clerk area 300 or not. For example, when there is no clerk in the clerk area 300, an advertisement screen can be displayed on the clerk-side display unit 210 as predetermined information for a customer who registers a product at the POS terminal 20 facing the clerk. is there. On the other hand, for example, when a clerk exists in the clerk area 300, a monitoring screen can be displayed on the clerk-side display unit 210 as predetermined information. The case where the monitoring screen is displayed will be described later with reference to FIG. As described above, the POS terminal 20 according to the present embodiment can cause the clerk-side display unit 210 to display predetermined information according to the set mode.

  In the present embodiment, a case will be described in which an advertisement screen and a monitoring screen are displayed as predetermined information, but the present invention is not limited to this. The predetermined information may be any content based on the transaction information received from the facing POS terminal 20, and may be, for example, information indicating a description of the purchased product or a recipe using the purchased product.

(About the presence or absence of a clerk in the clerk area 300)
Next, the presence or absence of a clerk in the clerk area 300 will be described. Each POS terminal 20 acquires presence information indicating that a clerk exists at a predetermined position. The predetermined position is, for example, the clerk area 300, and more specifically, may be an area in front of the terminal in the clerk area 300 (an area where the clerk stands when the terminal is operated). . Examples of the presence information include the following information (1) to (4).
(1) Information indicating that the clerk side display unit 210 has been operated.
(2) Information indicating the presence of a clerk for each time zone, obtained from store schedules and attendance information.
(3) When the POS terminal 20 has a reader for short-range wireless communication, it is determined that the reader has detected an employee ID tag (RFID tag or NFC tag) storing ID information of a clerk. Information to indicate.
(4) A detection result in the case where the presence of a clerk in the clerk area 300 is detected by an external camera installed on the ceiling or wall of the store.

Further, the POS terminal 20 acquires absence information indicating that there is no clerk at a predetermined position. If the POS terminal 20 does not acquire the presence information for a predetermined time or more, the POS terminal 20 generates and acquires the absence information by determining that the clerk is absent. The POS terminal 20 may acquire the absence information from an external device (for example, the management server 10). The absence information includes, for example, information shown in the following (1) to (4).
(1) Information indicating that the clerk side display unit 210 has not been operated for a predetermined time or more.
(2) Information indicating the absence of a clerk for each time zone, obtained from the store schedule and attendance information.
(3) Information indicating that the tag of the employee ID card held by the clerk has not been detected by the reader for short-range wireless communication.
(4) Information indicating that a clerk is not detected by an external camera installed on a ceiling, a wall, or the like of a store.

  When there is no clerk in the clerk area 300, both the POS terminal 20-A and the POS terminal 20-C display advertisements. More specifically, the POS terminal 20-A transmits transaction information (information related to a transaction) to the POS terminal 20-C. The transaction information referred to here is information necessary for displaying an advertisement, and specifically, registered product information, information indicating a payment type, member information, and a member card having a credit card function ( Hereinafter, this information is referred to as “member credit card”).

  Upon receiving the transaction information from the POS terminal 20-A, the POS terminal 20-C displays an advertisement on the clerk-side display unit 210 based on the transaction information. That is, the POS terminal 20-C displays an advertisement on the clerk-side display unit 210 for a customer who registers a product at the POS terminal 20-A. Similarly, the POS terminal 20-C transmits the transaction information to the POS terminal 20-A. Upon receiving the transaction information from the POS terminal 20-C, the POS terminal 20-A displays an advertisement on the clerk-side display unit 210 based on the transaction information. That is, the POS terminal 20-A displays an advertisement on the clerk-side display unit 210 for a customer who registers a product at the POS terminal 20-C. The POS terminal 20 that has performed the advertisement display ends the advertisement display when receiving the information indicating that the customer's checkout process is completed from the POS terminal 20 that is arranged opposite to the POS terminal 20.

  Here, as described above, during congestion, the POS terminal 20 on the upstream side is in the normal mode, and the POS terminal 20 on the downstream side is in the accounting-only mode. In the accounting-only mode, the clerk-side display unit 210 of the downstream POS terminal 20 is not used for registering a product. Therefore, both the POS terminal 20-B and the POS terminal 20-D on the downstream side may perform advertisement display.

  Specifically, a configuration for displaying an advertisement in the accounting-only mode will be described. The POS terminal 20 on the upstream side transmits transaction information to the POS terminal 20 on the downstream side of another lane. Specifically, the POS terminal 20-A transmits the transaction information to the POS terminal 20-D. Further, the POS terminal 20-C transmits the transaction information to the POS terminal 20-B. Upon receiving the transaction information from the POS terminal 20 on the upstream side of another lane, the downstream POS terminal 20 displays an advertisement based on the transaction information. Thereby, for example, when a customer who has performed product registration at the POS terminal 20-A moves to the POS terminal 20-B and performs payment, the clerk side display unit 210 of the POS terminal 20-D displays the customer's information. It is possible to display advertisement information based on transaction information.

  Then, the POS terminal 20-D on the downstream side ends the advertisement display when the settlement of the customer is completed. Specifically, the POS terminal 20-D on the downstream side ends the advertisement display when receiving the information indicating that the checkout process of the customer is completed from the POS terminal 20-B. In this manner, even when the upstream POS terminal 20 is in the normal mode and the downstream POS terminal 20 is in the accounting-only mode, the advertisement is displayed on the clerk-side display unit 210 at the downstream POS terminal 20 in the accounting-only mode. It is possible to display information.

(Example of advertisement information table)
Next, an example of the advertisement information table will be described with reference to FIG. FIG. 24 is an explanatory diagram illustrating an example of the advertisement information table. In FIG. 24, the advertisement information table 80 has fields for transaction information and advertisement data. The transaction information includes information indicating the presence or absence of a member credit card (member card having a credit card function), product information, and attribute information (sex, age). By setting information in fields corresponding to each information, the advertisement information 81 (81a, 81b) is stored as a record. In addition, in the advertisement information table 80 shown in FIG. 24, for the sake of description, information indicating the presence or absence of a member credit card and attribute information are separately displayed, but information indicating the presence or absence of a member credit card is also included in the attribute information.

  The information indicating the presence or absence of the member credit card indicates one of “Yes” and “No”. “Yes” indicates that the member card has a credit card function. “None” indicates that there is no member card without a credit card function or that there is no member card itself (no membership registration). The merchandise information indicates the classification of the merchandise purchased by the customer, and indicates, for example, food, alcohol, miscellaneous goods, and the like. The attribute information indicates gender and age.

  The advertisement data includes information indicating an advertisement for a product or a store, and is image data of a moving image or a still image. By using such an advertisement information table 80, the POS terminal 20 can select advertisement data according to the presence or absence of member credit card, product information, and customer attribute information. If the advertisement data corresponding to the registered product is not stored, advertisement data corresponding to a product similar to the product may be selected, or a product that tends to be purchased in combination with the product. May be selected. Further, when specific attribute information cannot be acquired, for example, when the customer does not have a membership card, the advertisement data may be selected assuming that the attribute information does not exist.

  Although FIG. 24 shows a case where one piece of advertisement data is set corresponding to the attribute information, a plurality of pieces of advertisement data may be set corresponding to the attribute information. When a plurality of pieces of advertisement data are set, the advertisement data to be displayed is switched when a predetermined time elapses for a still image or when a series of reproduction times elapses for a moving image. Thus, a plurality of types of advertisement data can be displayed during registration of a product. In addition, to select one piece of advertisement data from a plurality of pieces of advertisement data, a selection may be made at random or in a predetermined order.

  In the advertisement information table 80, the product information may be classified in detail. For example, food products may be classified into vegetables, meat, fish, confectionery, and the like. Further, the attribute information may include other information such as a family structure for each customer, a past purchase history, a hobby, and the like, in addition to the gender and the age. In this way, by making the transaction information more detailed, for example, it is possible to display different advertisements for customers who purchase vegetables and customers who purchase meat, or to display advertisements according to the family structure. Because it is possible, it is possible to perform more detailed advertisement display according to each customer.

  Note that the advertisement information table 80 shown in FIG. 24 shows a case where the information is set in a store that handles groceries such as a supermarket. For example, if the store is a store such as a home improvement center, a clothing store, and a sporting goods store, the store is It is sufficient that the advertisement information is set in accordance with the product handled in.

(An example of an advertisement screen displayed on the clerk-side display unit 210)
Next, an example of an advertisement screen (advertisement display) displayed on the clerk-side display unit 210 will be described with reference to FIG. FIG. 25 is an explanatory diagram illustrating an example of an advertisement screen displayed on the clerk-side display unit 210.

  FIG. 25A shows an advertisement screen for a new product, Shochu High, which is displayed, for example, when a man in his 30s or older has purchased alcoholic beverages. FIG. 25 (b) shows a curry advertisement screen for a new product, which is displayed, for example, when a customer in their 20s to 40s purchases food. FIG. 25 (c) shows an advertisement screen exclusively for members having member credit cards, and is an advertisement screen showing future special sale products. FIG. 25D shows an advertisement screen of a customer who does not have member credit card, and is an advertisement screen showing a privilege when the member credit card is used. When each advertisement screen is a moving image, the displayed image and contents change as time passes. When each advertisement screen is displayed, a sound is also output.

  Since the clerk area 300 is interposed between the POS terminal 20-A and the POS terminal 20-C (see FIG. 23), the customer who registers the product at the POS terminal 20-A and the POS terminal 20-A There is a distance corresponding to the clerk area 300 between the clerk side display unit 210 and C. Therefore, in the advertisement display, only information that is easy for the customer to grasp, such as a large character or a photograph of an outline of a product, may be displayed without displaying fine characters.

  Further, when the customer registers the product, the customer may be notified that the advertisement is being displayed on the POS terminal 20 facing the customer. Specifically, for example, when a customer is registering a product at the POS terminal 20-A, an advertisement is displayed on the clerk-side display unit 210 of the POS terminal 20-C at the POS terminal 20-A. A notification (including a sound) indicating that the communication is being performed may be performed.

  Further, when an advertisement of a moving image is displayed on the clerk-side display unit 210 of the POS terminal 20-C, the sound of the moving image may be output from the POS terminal 20-A. That is, the image of the moving image may be displayed on the clerk-side display unit 210 of the POS terminal 20-C, and the sound may be output on the POS terminal 20-A (own terminal).

  In addition, the content of the advertisement display may be such that the customer who saw the advertisement display goes to the merchandise counter again to promote shopping, but since the customer has already completed shopping, the content is not the content for prompting shopping again. Things are desirable. Specifically, it is desirable that the content of the advertisement display is information that prompts a visit to the store after the next time, such as information on future sales at the store or information on a new product to be released in the future.

(Overview of monitoring display in full self mode)
Next, an outline of the monitoring display in the full self mode will be described. FIG. 26 and FIG. 27 are explanatory diagrams showing an outline of the monitoring display in the full self mode. As shown in FIG. 26, it is assumed that one clerk has entered the clerk area 300 between the POS terminals 20-A and 20-C. In this case, the other POS terminals 20 (20-A, 20-B, 20-D) except the POS terminal 20-C transmit the transaction information to the POS terminal 20-C. The transaction information referred to here is information necessary for performing the monitoring display. Specifically, the information indicates the display screen of each POS terminal 20, the information indicating the registered merchandise, the amount at the time of settlement (total amount). Information such as the amount of money and the amount of money to be input).

  In this specification, for convenience of explanation, it is assumed that the POS terminal 20-C receives the transaction information from another POS terminal 20 at the timing when the clerk enters the clerk area 300. The transaction information may be always received without being limited to the timing of entering the service. Thus, each POS terminal 20 can always share the transaction information of the POS terminal 20 excluding the own device.

  When the clerk enters the clerk area 300, the POS terminal 20-C causes the clerk-side display unit 210 to display a monitoring screen related to customer operations at the own terminal and other POS terminals 20. The monitoring screen, which will be described in detail later, is a mirror display (mirror display) that displays a screen that is the same as or similar to the screen displayed on the customer-side display unit 205 of each POS terminal 20, or a status (display) in each POS terminal 20. Display during registration or accounting).

  Although not shown in FIG. 26, when the clerk enters the clerk area 300 between the POS terminals 20-A and 20-C, a monitoring screen can be displayed on the POS terminal 20-A. is there. Specifically, when the clerk enters the clerk area 300, the POS terminal 20-A receives transaction information from the other POS terminals 20 (20-B, 20-C, 20-D) except the POS terminal 20-A. , It is possible to display a monitoring screen. Note that the monitoring screen displayed on the POS terminal 20-A and the monitoring screen displayed on the POS terminal 20-C may be different from each other. For example, one terminal may display the status of each terminal, and the other terminal may display a mirror screen.

  When the monitoring screen is displayed on the POS terminal 20-A, the store clerk may be notified that the monitoring screen is displayed on both the POS terminals 20-A and 20-C. This notification may be, for example, a notification that prompts the clerk to delete one of the POS terminals 20-A, or a notification that the clerk selects the one to be deleted. In addition, the clerk operates the POS terminal 20 (POS terminal 20-C) to be browsed by the clerk to automatically delete the monitoring screen of the other (POS terminal 20-A) out of the POS terminals 20-A and 20-C. You may. Further, when the clerk enters the clerk area 300 between the POS terminals 20-A and 20-C, it is set in advance which terminal is to display the monitoring display, and the monitoring screen is displayed only on the set terminal. It may be displayed.

  Further, when the monitoring screen of the clerk-side display unit 210 of the POS terminal 20-A is erased, the clerk-side display unit 210 may be set to a halt state, or an advertisement screen may be displayed. When the advertisement screen is displayed, the presence of the clerk in the clerk area 300 may reduce the visibility of the advertisement screen for the customer. Therefore, the advertisement data of the moving image may be played back at the POS terminal 20-A, and the sound of the moving image may be output at the POS terminal 20-C. That is, from the viewpoint of a customer who registers a product at the POS terminal 20-C, a voice advertisement may be performed.

  Also, as shown in FIG. 26, since there is no clerk between the POS terminal 20-B and the POS terminal 20-D in the clerk area 300, the POS terminals 20-B and 20-D In any case, an advertisement may be displayed. That is, in a configuration in which one island is formed by four devices, some terminals (POS terminals 20-C) perform monitoring display, and some other terminals (POS terminals 20-B and 20-D) display advertisements. Display may be performed in some cases.

  Also, as shown in FIG. 27, when a clerk enters the clerk area 300 between the POS terminals 20-B and 20-D due to a call from a customer or the like, the POS terminals 20-B and 20-D enter the clerk area. A monitoring screen is also displayed. Although not shown in FIG. 27, the POS terminal 20-B receives the transaction information from the other POS terminals 20 (20-A, 20-C, 20-D) except the POS terminal 20-B. Then, a monitoring screen corresponding to the received information is displayed. Similarly, a monitoring screen can be displayed on the POS terminal 20-D.

(An example of a monitoring screen displayed on the clerk-side display unit 210)
Next, an example of a monitoring screen displayed on the clerk-side display unit 210 will be described with reference to FIGS. FIG. 28 is an explanatory diagram illustrating an example of a monitoring screen indicating a status. FIG. 29 is an explanatory diagram showing an example of details of a monitoring screen showing details of each POS terminal.

  The monitoring screen shown in FIGS. 28 and 29 shows a four-divided screen divided into regions indicating each POS terminal 20. The monitoring screen is not limited to the four-split screen. For example, a six-split screen may be used when monitoring six POS terminals 20, and an eight-split screen may be used when eight POS terminals 20 are monitored. It is also possible.

  The symbols shown in (A) to (D) of FIG. 28 and the symbols shown in (A) to (D) of FIG. 29 are assigned to the POS terminals 20-A, 20-B, 20-C, and 20-D. Correspond to each. For example, FIG. 28A shows the status of the POS terminal 20-A, and specifically shows that the account is being settled. Similarly, FIGS. 28B to 28D show the corresponding statuses of the POS terminal 20.

  FIGS. 29A to 29D each show a detailed display including a mirror screen displayed on each terminal. The mirror screen does not need to be exactly the same as the screen displayed on the customer-side display unit 205 of each POS terminal 20. For example, the clerk-side display unit 210 displays buttons operated by a clerk, May be displayed to alert the user when a product to be checked is registered. An arrangement image 401 is displayed at the center of the screen shown in FIG. The layout image 401 shows the layout of each of the POS terminals 20-A to 20-D. “〇” shown in the arrangement image 401 indicates the POS terminal 20 (POS terminal 20-C) on which the monitoring screen is displayed.

  For example, in FIG. 29A, a confirmation display 402 is displayed in a pop-up manner on the mirror screen of the POS terminal 20-A. The confirmation display 402 is a display for confirming whether or not the user is an adult, for example, by registering an alcoholic beverage product. The reception button shown in the confirmation display 402 may be operated by, for example, a clerk. Specifically, the store clerk may look at the customer, or the store clerk may receive an identification card or the like from the customer, determine whether or not the person is an adult, and operate the store clerk. Further, by displaying the confirmation display 402 on the customer-side display unit 205, the reception button shown in the confirmation display 402 may be operated by the customer. In the case where the customer is caused to operate, the fact that the confirmation display 402 has been displayed on the customer side display unit 205 may be displayed on the monitoring screen, that is, the visual confirmation by the clerk (the confirmation of whether the customer is an adult or not) ) May be performed.

  In addition, the target product for which the confirmation display 402 is performed is not limited to a product that is prohibited from being sold to a minor, and may be a single product such as a canned coffee or a pack of a plurality of (six) products. However, it may be a product that can be purchased. In the case of such a product that can be purchased as a single item or a pack, there is a barcode displayed on the pack and a barcode displayed on the canned coffee itself (single item). However, if the barcode of a single item is exposed from the pack, the customer may erroneously read the barcode of the single item.

  For this reason, in the case of a product that can be purchased as a single item or a pack, erroneous input by the customer can be suppressed by displaying a confirmation display 402 as to whether the purchase target is a single item or a pack on the customer side display unit 205. Becomes possible. Also, if the customer selects a pack in the confirmation display 402 after registering a single item (if corrected), the product to be registered is changed to a pack, and the registered single item is changed. You may delete it.

  In addition, a confirmation display 402 indicating whether the purchase target is a single item or a pack may be displayed on the clerk-side display unit 210. In this case, for example, the clerk may select the purchase target in the confirmation display 402. In addition, by notifying that the confirmation display 402 is being performed on the customer side display unit 205, it is possible to notify the clerk that products that can be purchased individually and in packs are registered. For this reason, the clerk can visually confirm the registration operation of the customer and can monitor whether or not the product to be purchased is properly registered.

  In FIG. 29B, a call display 403 is displayed in a pop-up manner on the mirror screen of the POS terminal 20-B. The call display 403 indicates, for example, that the clerk call button BT33 (see FIG. 15B) has been operated by the customer at the POS terminal 20-B. The call display 403 displays the operation history such as the fact that the customer called the clerk, the time when the product was registered and the time when each operation was received, and the registered product. Further, the notice of “☆ No operation for more than 1 minute” in the call display 403 is a comment display of an abnormal change estimated from the operation history. The comment indicating the anomaly may be a comment indicating the type of the error (the reason for the call), a comment indicating a countermeasure for the error, or the like.

  More specifically, for example, a comment indicating an anomaly indicates that the operation history shown in the call display 403 indicates that the call button BT33 has been pressed after the subtotal button has been pressed, so there is a possibility of a trouble at the time of settlement. May be a comment that indicates Further, the comment may be further subdivided, and for example, when cash is inserted after the subtotal button is pressed, the comment may indicate that there is a possibility of a trouble related to payment. If the cash has not been inserted, the comment may indicate that the customer may have unintentionally pressed the subtotal button BT33.

  Thus, the clerk can check the contents of the call display 403 and respond to the customer of the POS terminal 20-B. Therefore, the clerk can respond to the customer by predicting the trouble, so that the time required for the customer's response can be shortened and an efficient response can be performed.

  In the confirmation display 402 and the call display 403, the font size and the pop-up display size are different depending on the priority (urgency). The priority is set for each response measure that the clerk performs for the customer. For example, the priority order may be set such that a measure requiring assistance is set high or a measure requiring a short response time is set high as a measure for dealing with a customer. The setting of such a priority order can be freely set in advance by an operator (store clerk). In FIG. 29, the pop-up of the call display 403 is displayed larger than the confirmation display 402, that is, the setting that requires assistance is prioritized. However, if the setting is such that the response time is short and priority is given, the pop-up of the confirmation display 402 is displayed larger than the call display 403.

  Here, as described above, during congestion, the POS terminal 20 on the upstream side is in the normal mode, and the POS terminal 20 on the downstream side is in the accounting-only mode. In this case, the POS terminals 20 on the downstream side mutually display advertisements. It is possible to do. On the other hand, a clerk is arranged on the POS terminal 20 on the upstream side, and the merchandise is registered using the clerk-side display unit 210. Therefore, even if a trouble occurs during the settlement at the POS terminal 20 on the downstream side, the clerk can deal with the trouble. Therefore, when the POS terminal 20 on the downstream side is in the accounting-only mode, the advertisement display may be executed, while the monitoring display may not be executed.

  The screen showing the status shown in FIG. 28 and the detail screen including the mirror screen shown in FIG. 29 may be switchable by the store clerk pressing a predetermined screen switching button. When an error occurs, that is, when the confirmation display 402 or the call display 403 is displayed, the screen may be switched to the detail screen. Further, in the four-split screen, a screen indicating the status and a mirror screen may be mixed. More specifically, in the four-split screen, a terminal that does not display the confirmation display 402 or the call display 403 displays a status screen, and a terminal that displays the confirmation display 402 or the call display 403 displays a mirror screen. May be displayed.

(Various processes performed by the POS terminal 20)
Next, various processes performed by the POS terminal 20 will be described with reference to FIGS.

(Example of Product Registration Process Performed by POS Terminal 20)
FIG. 30 is a flowchart illustrating an example of a product registration process performed by the POS terminal 20.
Step S101: The POS terminal 20 determines whether or not attribute information (member information) has been acquired. When not acquiring the attribute information, the POS terminal 20 proceeds to step S103. When the POS terminal 20 acquires the attribute information, the process proceeds to step S102. Note that the POS terminal 20 may perform, for example, a notification that accepts selection of “present” or “absent” of the membership card before step S101. When the selection of “Yes” is received, a notification prompting insertion of a membership card (input of attribute information) may be performed. Further, when the selection of “absent” is received, information (attribute information) indicating the selection may be transmitted to the POS terminal 20 facing the terminal.

Step S102: The POS terminal 20 transmits the acquired attribute information to the POS terminal 20 that is arranged opposite, and proceeds to step S103.
Step S103: The POS terminal 20 determines whether there is a scan or the like, such as touching the clerk-side display unit 210, operating the key operation unit 211, and reading by the clerk-side scanner unit 212. If there is no scan or the like, the POS terminal 20 proceeds to step S106. If there is a scan or the like, the POS terminal 20 proceeds to step S104.

Step S104: The POS terminal 20 registers the product, displays the registered product on the customer-side display unit 205 and the clerk-side display unit 210, and proceeds to step S105.
Step S105: The POS terminal 20 transmits the transaction information including the information of the registered merchandise and the screen information being displayed to the opposing POS terminal 20, and proceeds to step S106.

Step S106: The POS terminal 20 determines whether or not the subtotal key of the key operation unit 211 has been pressed. If the subtotal key has not been pressed, the process returns to step S101. When the subtotal key is pressed, the POS terminal 20 proceeds to step S107.
Step S107: The POS terminal 20 performs a settlement process, and proceeds to step S108. In the settlement process, when the POS terminal 20 displays the sub-planning surface and accepts a settlement operation such as input of a deposit and pressing of a current total button, the POS terminal 20 issues a receipt or the like. In the settlement process, a deposit according to the deposit or a change according to the current total in the settlement process may be released. In the settlement process, transaction history information (sales data) is stored.

Step S108: The POS terminal 20 determines whether the settlement process has been completed. The POS terminal 20 waits until the settlement process ends, and proceeds to step S109 when the settlement process ends.
Step S109: The POS terminal 20 transmits payment end information indicating that the payment has been completed to the opposing POS terminal 20, and ends a series of processing.

(An example of the preceding process of the advertisement display or the monitoring display performed by the POS terminal 20)
FIG. 31 is a flowchart illustrating an example of a preceding process of the advertisement display or the monitoring display performed by the POS terminal 20. The processing shown in the flowchart of FIG. 30 is always started (periodically at very short time intervals) in each POS terminal 20.

  Step S121: The POS terminal 20 determines whether or not the current mode is the full self mode. If the current mode is not the full self mode, the POS terminal 20 ends a series of processing. If the current mode is the full self mode, the POS terminal 20 proceeds to step S122.

Step S122: The POS terminal 20 determines whether or not a clerk exists in the clerk area 300. When there is no clerk in the clerk area 300, the POS terminal 20 proceeds to step S123. If there is a clerk in the clerk area 300, the POS terminal 20 proceeds to step S124.
Step S123: The POS terminal 20 performs an advertisement display process (see FIG. 32), and ends a series of processes.

Step S124: The POS terminal 20 determines whether or not the advertisement display on the clerk side display unit 210 is being executed. When the POS terminal 20 is not performing the advertisement display, the process proceeds to step S126. If the POS terminal 20 is performing the advertisement display, the process proceeds to step S125.
Step S125: The POS terminal 20 ends the advertisement display displayed on the clerk-side display unit 210, and proceeds to step S126.
Step S126: The POS terminal 20 performs monitoring display processing (see FIG. 33), and ends a series of processing.

(Example of advertisement display processing performed by POS terminal 20)
FIG. 32 is a flowchart illustrating an example of an advertisement display process performed by the POS terminal 20.
Step S131: The POS terminal 20 determines whether or not attribute information (transaction information) has been received from the opposite POS terminal 20. When the POS terminal 20 does not receive the attribute information from the opposing POS terminal 20, the process proceeds to step S133. When the POS terminal 20 receives the attribute information from the opposing POS terminal 20, the process proceeds to step S132.

Step S132: The POS terminal 20 stores the attribute information in a predetermined storage area such as the RAM 203, and proceeds to step S133. The attribute information includes information indicating the presence or absence of a member credit card and information indicating that the user does not have a member card.
Step S133: The POS terminal 20 determines whether or not merchandise information (transaction information) has been received from the opposite POS terminal 20. When the POS terminal 20 does not receive the product information from the opposing POS terminal 20, the process proceeds to step S135. When the POS terminal 20 receives the product information from the opposing POS terminal 20, the process proceeds to step S134.

Step S134: The POS terminal 20 stores the transaction information including the attribute information and the product information in a predetermined storage area such as the RAM 203, and proceeds to step S135.
Step S135: The POS terminal 20 determines whether an advertisement is being displayed. When the POS terminal 20 is not displaying the advertisement, the process proceeds to step S136. If the advertisement is being displayed, the POS terminal 20 proceeds to step S137.
Step S136: The POS terminal 20 determines whether or not transaction information including attribute information and product information is stored. When the POS terminal 20 stores the transaction information, the process proceeds to Step S138. When the POS terminal 20 does not store the transaction information, the process proceeds to Step S140.

  Step S137: The POS terminal 20 determines whether or not it is time to switch the advertisement display. When it is the switching timing of the advertisement display, the POS terminal 20 proceeds to step S138. When it is not the switching timing of the advertisement display, the POS terminal 20 proceeds to step S139.

Step S138: The POS terminal 20 refers to the advertisement information table 80 (see FIG. 24), selects advertisement information based on the attribute information and the product information, and displays the selected advertisement information on the clerk-side display unit 210. Proceed to S140.
Step S139: The POS terminal 20 determines whether or not to perform mode switching. Specifically, the POS terminal 20 determines whether or not the press of the mode switching button 211a has been received and whether or not a mode switching command has been received. When the POS terminal 20 does not perform the mode switching, the process proceeds to step S140. When performing the mode switching, the POS terminal 20 proceeds to step S141.

Step S140: The POS terminal 20 determines whether or not payment end information has been received from the opposing POS terminal 20. If the POS terminal 20 does not receive the settlement end information from the opposing POS terminal 20, the process returns to step S131. When the POS terminal 20 receives the settlement end information from the opposing POS terminal 20, the process proceeds to step S142.
Step S141: The POS terminal 20 performs a mode switching process, and proceeds to step S142.
Step S142: The POS terminal 20 ends the advertisement display displayed on the clerk-side display unit 210, and ends a series of processing.

  The timing of starting the advertisement display will be described in detail. For example, when the POS terminal 20 receives (stores) the attribute information (member information) before receiving (stores) the product information, only the relevant attribute information is received. May be displayed based on the advertisement. Further, for example, when the POS terminal 20-C receives (stores) the product information before receiving the attribute information, the POS terminal 20-C may start displaying the advertisement based on only the product information. Further, for example, when both the attribute information and the product information are received (stored), the POS terminal 20-C may start displaying the advertisement based on the information.

  The timing of ending the advertisement display is exemplified in the following (1) to (6).

(1) Since the playback time of the moving image (for example, 15 seconds) is set in advance, the process ends (at the timing) when the playback time has elapsed.
(2) The process ends when the transaction of the customer to be displayed the advertisement ends.
(3) The process ends (at the timing) when the customer to be displayed with the advertisement disappears from the front of the POS terminal 20 that has made the transaction. In order to determine whether or not there is a customer in front of the POS terminal 20, for example, a human sensor may be used.
(4) When a clerk enters (exists) in front of the POS terminal 20 displaying the advertisement information, the process ends (at a timing).
(5) When the clerk operates the POS terminal 20 displaying the advertisement information, the process ends (at a timing).
(6) When the mode of the POS terminal 20 displaying the advertisement information is switched with the mode switching of the other device, the process ends (at a timing).

  The operation of the POS terminal 20 according to the above (1) to (6) will be supplemented.

(1) Some advertisement displays are based on video playback. The length per video is, for example, about 15 seconds. When the reproduction time of 15 seconds elapses, the moving image ends (step S137). For this reason, when only one type of advertisement information is reproduced, the advertisement display may be ended without waiting for the customer to finish the payment (step S140: YES). That is, the process of step S140 may be omitted.

(2) When the transaction of the customer (customer targeted for the advertisement display) is completed during the reproduction of the video, specifically, when the settlement is completed, even if the video is being reproduced, Then, the reproduction of the moving image ends (step S140: YES → step S142). If the customer (customer targeted for advertisement display) is continuing the transaction at the end of the video, the same video (advertisement display) or a different video is continuously played (step S137: NO) → Step S139: NO → Step S140: NO).

(3) When it is determined that there is a customer in front of the POS terminal 20 instead of or in addition to the determination of whether or not the payment end is received in step S140, and it is determined that the customer is gone. Then, the video may be ended.
(4) Also, if the clerk enters the clerk area during the reproduction of the moving image, the moving image is forcibly terminated (Step S122: YES → Step S124: YES → Step S125 in FIG. 31).

(5) Instead of or in addition to the determination of whether or not a clerk exists in step S122, it is determined whether or not the clerk has operated the POS terminal 20 on the side displaying the advertisement, and the clerk determines whether the POS has been activated. When it is determined that the terminal 20 has been operated, the moving image may be ended.
(6) Also when the mode switching is detected, the moving image is forcibly terminated (step S139: YES → step S141 → step S142).

(Example of monitoring display processing performed by POS terminal 20)
FIG. 33 is a flowchart illustrating an example of the monitoring display process performed by the POS terminal 20.
Step S151: The POS terminal 20 displays a monitoring screen, and proceeds to step S152.
Step S152: The POS terminal 20 determines whether to switch the display of the monitoring screen. If the POS terminal 20 does not switch the display of the monitoring screen, the process proceeds to step S154. When the POS terminal 20 switches the display of the monitoring screen, the process proceeds to step S153. Note that the display switching is performed, for example, when a selection to perform the display switching is received or when a customer calls.

Step S153: The POS terminal 20 switches the monitoring screen, and proceeds to step S154. The switching of the monitoring screen is, for example, switching between a monitoring screen showing the status (see FIG. 28) and a monitoring screen showing the details of each POS terminal (see FIG. 29).
Step S154: The POS terminal 20 determines whether a clerk is present. If the POS terminal 20 exists, the process proceeds to step S155. If there is no clerk, the POS terminal 20 proceeds to step S157.

Step S155: The POS terminal 20 determines whether or not to perform mode switching. When the POS terminal 20 does not perform the mode switching, the process returns to step S151. When performing the mode switching, the POS terminal 20 proceeds to step S156.
Step S156: The POS terminal 20 performs a mode switching process, and proceeds to step S157.
Step S157: The POS terminal 20 ends the monitoring display displayed on the clerk-side display unit 210, and ends a series of processing.

(Another example of advertisement display in “Island”)
FIG. 34 is an explanatory diagram showing another example of the advertisement display in the “island”. In FIG. 34, each POS terminal 20 is set to the full self mode. As shown in FIG. 34, customers are conducting transactions at the POS terminals 20-A, 20-C, and 20-D except for the POS terminal 20-B. As described above, each POS terminal 20 can display an advertisement. Here, since there is no customer at the POS terminal 20-B, an advertisement does not have to be displayed on the screen of the clerk-side display unit 210 of the POS terminal 20-D. The clerk-side display unit 210 of the terminal 20-D cannot be effectively used.

  Therefore, in the example illustrated in FIG. 34, an advertisement is displayed on the clerk-side display unit 210 of the POS terminal 20-D for customers who are transacting at the POS terminal 20-A. Specifically, the POS terminal 20-A transmits the transaction information not only to the POS terminal 20-C but also to the POS terminal 20-D. Upon receiving the transaction information from the POS terminal 20-A, the POS terminal 20-D displays an advertisement on the clerk-side display unit 210 based on the transaction information. That is, the POS terminal 20-D displays an advertisement on the clerk-side display unit 210 for a customer who registers a product at the POS terminal 20-A. Thereby, an advertisement can be displayed to the customer of the POS terminal 20-A using the clerk-side display units 210 of the POS terminals 20-C and 20-D.

  In this case, for example, the advertisement display corresponding to the product purchased by the customer may be divided into two and displayed on the clerk-side display unit 210 of each of the POS terminals 20-C and 20-D. Specifically, for example, when there are a plurality of types of advertisement information corresponding to the products purchased by the customer, different types of advertisement information may be displayed on the clerk-side display units 210. If it is possible to divide the screen showing the advertisement information corresponding to the product purchased by the customer into a plurality of screens and display the divided screens on the clerk-side display sections 210 (enlarged display), Is also good.

  Further, when there is advertisement information corresponding to each of the different products purchased by the customer, different advertisement information corresponding to each product may be displayed on each clerk-side display unit 210. Further, one clerk-side display unit 210 may display advertisement information based on a product purchased by a customer, and the other clerk-side display unit 210 may display advertisement information based on payment information.

  As described above, in the present embodiment, the monitoring screen and the advertisement screen for each customer can be displayed on the clerk side display unit 210 in the full self mode according to the presence or absence of the clerk in the clerk area 300. Therefore, in the full self mode, the clerk-side display unit 210 can be effectively used without stopping.
