It has a return port for returning foreign currency, etc.), calculates the amount of money to be put into the slot, calculates the change amount which is the difference between the amount of money to be put in and the amount of purchase, and discharges the change from the outlet. The change machine 209 is directed toward the customer and is operated by the customer. When bills or coins are inserted into the slot, they are detected by a sensor (detection that there was insertion, detection of the number of coins by denomination, etc.). A settlement unit is formed by the card settlement unit 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 is composed of various keys (hardware keys, buttons) and receives various inputs from a clerk.
The clerk side scanner unit 212 is a scanner unit for clerk, optically images various information, extracts a code (for example, a bar code or a two-dimensional code) from the captured image, and information from the code. Read (decode or decode). For example, the clerk-side scanner unit 212 optically reads the bar code attached to the product or the clerk code attached to the clerk's name tag. In addition to the above, the clerk-side scanner unit 212 may read the code printed on the checkout ticket, the gift certificate, and the code printed on various cards.

The clerk side scanner unit 212 is used when the clerk registers the 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 in the key operation unit 211, the clerk operates (presses) the key and registers the product. Good. Further, when the preset key corresponding to the 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 (receipt, checkout ticket, etc.). The printing unit 213 can rotatably change the direction 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, etc.) based on, for example, switching of the 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. It should be noted that switching the operation mode is also called shifting the operation mode.

(Overview of each operation mode)
Subsequently, the operation mode of the POS terminal 20 will be described. The POS terminal 20 has a plurality of operation modes. The operation mode is an operation mode during normal work (operation mode related to registration processing and settlement processing), and is an aggregation mode for totaling and inquiring sales, sales, etc., and setting work and maintenance work by a clerk or maintenance staff. It does not include the maintenance mode for training and the training mode for newcomers.

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

In FIG. 5A, columns indicate each operation mode, and rows indicate each function (“product registration (clerk side)”, “product registration (customer side)”, “money insertion”, ..., “O). "Reading the accounting ticket") is shown. The same applies to FIG. 5 (B) (however, in FIG. 5 (B), the illustration of each function is omitted).

In FIG. 5 (A) (the same applies to FIG. 5 (B)), "○" in the column specified from the column and the row indicates that the function of the row is enabled in the operation mode of the column. .. For example, "○" in the column specified from the column "normal mode (standard mode)" and the row "product registration (clerk side)" enables product registration (clerk side) in the normal mode (standard mode). It shows that. Further, "-" in the column specified from the column and the row indicates that the function of the row is disabled 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.

(Explanation of each function)
Hereinafter, the outline of each function shown in FIG. 5 (A) will be described.

(Product registration (clerk side))
The "product registration (clerk side)" is a function of registering the purchased product in the clerk side registration unit (the clerk side scanner unit 212, the clerk side display unit 210, the key operation unit 211). That is, it is a function of executing the registration process of the purchased product by the operation of the clerk (scanning by the clerk side scanner unit 212, touching the clerk side display unit 210, operation of the key operation unit 211).

(Product registration (customer side))
"Product registration (customer side)" is a function of registering purchased products in the customer side registration unit (customer side scanner unit 206, customer side display unit 205). That is, it is a function of executing the registration process of the purchased product by the operation of the customer (scanning by the customer side scanner unit 206, touching the customer side display unit 205).

(Insert money)
"Insert money" is a function that accepts the insertion of money (banknotes, coins). That is, it is a function of accepting a cash settlement operation (inserting money into the change machine 209).

(Sending registration information to other terminals)
"Sending registration information to another terminal" transmits the registration information generated in the registration process to another terminal (another terminal capable of performing settlement processing, for example, another POS terminal 20) (directly to another terminal). It is a function of transmitting or indirectly transmitting to another terminal via the store controller 10 or a monitoring terminal (hereinafter, the same applies).

(Issuance of accounting ticket)
"Issuing an accounting ticket" is a function of encoding registration information and the like generated in the registration process and issuing a printed medium (accounting ticket).

(Reception of registration information from other terminals)
"Reception of registration information from another terminal" receives registration information generated in the registration process of another terminal (directly receives from another terminal or indirectly via a store controller 10 or a monitoring terminal). It is a function to receive from other terminals. The same applies hereinafter). The terminal that has received the registration information from another terminal executes the settlement process based on the registration information.

(Reading the accounting ticket)
"Reading the accounting ticket" is a function of reading the accounting ticket (specifically, the code printed on the accounting ticket or the coded information). The terminal that has read the checkout ticket issued by the other terminal executes the settlement process based on the registration information acquired by reading the checkout ticket.

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

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

In the normal mode (standard mode), as shown in FIG. 5 (A), the insertion of money, the transmission of registration information to other terminals, and the issuance of accounting tickets are all valid "○". The operation mode. That is, in the normal mode (standard mode), the settlement process after the registration process on the clerk side can be executed on the own terminal or on another terminal. Specifically, in the normal mode (standard mode), the settlement process is executed on the own terminal by accepting the input of money into the change machine 209, and the registration information is transmitted to another terminal (or the checkout ticket is sent). Have another terminal execute the settlement process (by issuing).

Further, as shown in FIG. 5A, the normal mode (standard mode) is an operation mode in which both the reception of registration information from another terminal and the reading of the checkout ticket are valid “◯”. That is, in the normal mode (standard mode), the settlement process can be executed based on the registration information generated in the other terminal. The settlement process after receiving the registration information (or after reading the checkout ticket) may be executed as the semi-self mode shown in FIG. 5A. That is, when the registration information is received (or the checkout ticket 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). You may ask for permission by) and execute the settlement process in the semi-self mode (accounting-only mode). In addition, when the payment process is executed after shifting to the semi-self mode (accounting-only mode), the semi-self mode (accounting-only mode) is automatically switched to the normal mode (standard mode) (permission by the clerk may be requested). It may be transitioned (returned) or left in the semi-self mode (accounting-only mode).

In the normal mode (standard mode), at least one of receiving registration information from another terminal and reading a checkout ticket may be invalidated "-".

FIG. 6 is a schematic diagram illustrating an outline of operation in the normal mode. FIG. 6 shows a case where payment is performed by the POS terminal 20 (own terminal) that has registered the product. In the normal mode, as shown in the upper part of FIG. 6, the clerk uses the clerk-side operation unit (the clerk-side scanner unit 212, the clerk-side display unit 210, the key operation unit 211, etc.) to receive the customer's purchased product. When the registration is completed, the clerk operates the subtotal key (for example, the subtotal key displayed on the clerk side display unit 210 or the subtotal key arranged on the key operation unit 211). When the subtotal key is operated, as shown in the lower part of FIG. 6, the customer confirms the total amount of the purchased products on the display unit 210 on the clerk side, inserts money (cash) into the change machine 209, or cards. Settlement is performed by operating the settlement unit 208. The subtotal key is an operation key for completing the registration process, and may be referred to as a subtotal button, a registration completion key, a registration completion button, a checkout key, a checkout button, or the like. In addition, some operation units on the clerk side may accept operations by the clerk other than the registration operation.

The POS terminal 20 can accept payment during the registration process, and the customer may wait until the registration process by the clerk is completed (until the total amount is fixed), but the registration process is completed. You may insert cash into the change machine 209 before doing so. Further, the POS terminal 20 can accept the selection of the payment method during the registration process, and the customer selects the payment method (also referred to as payment type, payment method, payment type) before the registration process is completed. May be good.

Further, the POS terminal 20 can register the purchased product of the next customer during the settlement process, and the clerk may wait until the settlement by the customer is completed (until the customer receives the change or receipt). , The next customer's purchased product may be registered. In addition, the customer may finish the reception during the payment of the customer, and the clerk may be absent during the payment by the customer. In addition, the POS terminal 20 controls the payout of change / fishing tag by the change machine 209 in order to prevent forgetting to take the change when there is change, and a sensor or the like that the customer has removed the change / fishing tag. The issuance of the receipt by the printing unit 213 may be controlled after recognizing the above. This point is the same in other operation modes.

FIG. 7 is a schematic diagram illustrating an outline of operation in the normal mode. FIG. 7 shows a case where payment is performed by another POS terminal (other terminal) different from the POS terminal 20 in which the product is registered. In the normal mode, as shown in the upper part of FIG. 7, the clerk registers the customer's purchased product with the clerk's registration device in the same manner as when the settlement process is performed on the own terminal. When the registration process by the clerk is completed and the subtotal key is operated, the customer moves to another POS terminal 20 (POS terminal 20-2 in the example of FIG. 7) as shown in the lower part of FIG. 7, and the clerk The total amount of the purchased products is confirmed on the side display unit 210, money is inserted into the change machine 209, or the card settlement unit 208 is operated to settle the payment. Information necessary for the settlement process (registration information generated in the POS terminal 20-1 and the like) is supplied to the other POS terminal 20 (POS terminal 20-2).

The clerk designates the POS terminal 20 (either the POS terminal 20-2 or the POS terminal 20-3 in the example of FIG. 7) to execute the settlement process on the POS terminal 20-1. Alternatively, the clerk causes the POS terminal 20-1 to issue a medium (accounting ticket) to be read by the POS terminal 20 (POS terminal 20-2 or POS terminal 20-3 in the example of FIG. 7) for executing the settlement process. You may.

Further, the clerk can register the purchased product of the next customer after designating the other POS terminal 20, and may be absent after designating the other POS terminal 20. Further, instead of designating another POS terminal 20 after pressing the subtotal key, another POS terminal 20 may be designated without pressing the subtotal key. For example, in order to place a subtotal key and a key for designating another POS terminal 20 on the registration screen (and a key for issuing a checkout ticket may also be placed) to specify the POS terminal 20. The registration information may be transmitted when the key of is pressed. Alternatively, an accounting ticket to be read by another POS terminal 20 may be issued so that the other POS terminal 20 may execute the settlement process. The key for issuing the checkout ticket may be pressed after the subtotal key is pressed, or may be pressed before the subtotal key is pressed.

After receiving the registration information, the other POS terminal 20 (POS terminal 20-2) that has received the registration information shifts (switches) to the semi-self mode (accounting-only mode) unless it is in the semi-self mode (accounting-only mode). The operation in the semi-self mode (accounting-only mode) will be further described later. Then, on the customer side, for example, the change machine 209 performs the settlement, and the processing on the settlement side is completed. After receiving the registration information, the other POS terminal 20 may execute the settlement process in the normal mode or the full self mode without shifting to the semi-self mode (accounting-only mode).

(Full self mode)
As shown in FIG. 5A, the full self mode is an operation mode in which the product registration (customer side) is set to valid “◯”. That is, the full self mode is an operation mode premised on the registration process on the customer side. However, in the full self mode, product registration (clerk side) is also valid "○". That is, the full self mode is an operation mode that allows the registration process on the clerk side while assuming the registration process on the customer side. The state in which 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, the product registration (clerk side) is set to valid "○" in the full self mode, but the product registration (clerk side) is set to invalid "-" in the full self mode. May be good.

In addition, as shown in FIG. 5 (A), the full self mode is an operation mode in which the insertion of money is set to "○" and the transmission of registration information to other terminals and the issuance of accounting tickets are set to "-". Is. That is, the full self mode is an operation mode premised on the settlement process in the terminal.

In addition, as shown in FIG. 5A, the full self mode is valid for both receiving registration information from other terminals and reading checkout tickets, as in the normal mode (standard mode). This is the operating mode. That is, as in the normal mode (standard mode), in the full self mode, the settlement process can be executed based on the registration information generated in the other terminal. The settlement process after receiving the registration information (or after reading the checkout ticket) may be executed as the semi-self mode shown in FIG. 5A. That is, when the registration information is received (or the accounting ticket is read) in the full self mode, the full self mode is automatically changed to the semi-self mode (accounting only mode), and the semi-self mode (accounting) is performed. The settlement process may be executed as a dedicated mode). In addition, when the settlement process is executed after shifting to the semi-self mode (accounting-only mode), the semi-self mode (accounting-only mode) may be automatically switched (returned) to the full-self mode, or the semi-self mode (return) may be performed. You may leave it as the accounting-only mode).

FIG. 8 is an explanatory diagram illustrating an outline of the operation of the full self mode. In the full self mode, as shown in the upper part of FIG. 8, the customer registers his / her purchased product with the customer-side registration device (customer-side scanner unit 206, customer-side display unit 205). When the registration process is completed, the customer presses the registration completion key (for example, the registration completion key displayed on the customer side display unit 205). When the registration completion key is pressed, the customer confirms the total amount of the purchased products on the customer side display unit 205 and inserts cash into the change machine 209, or the card settlement unit 208, as shown in the lower part of FIG. Operate and settle. The registration completion key is an operation key for completing the registration process, and may be referred to as a registration completion button, a subtotal key, a subtotal button, a checkout key, a checkout button, or the like.

In the full self mode, the customer side executes both the registration process and the settlement process, but the clerk side does not mean that nothing can be done. That is, even when the POS terminal 20 is operating in the full self mode, for example, the clerk scans the product (double scan mode) and the clerk displays various information. It is possible. The mode in which the clerk can scan the product during the full self mode may be called the double scan mode. In the double scan mode, the clerk may wait until the customer's payment is completed (until the customer changes or receives the receipt), but may register the next customer's purchased product. In addition, the clerk may be absent during the payment by the customer.

The transition from the full self mode to the double scan mode may be performed, for example, when the clerk code is read in the full self mode. Reading the clerk code may be one of the login operations. Further, the operation mode may shift from the full self mode to the double scan mode when there is another operation (for example, a login operation different from reading the clerk code) in the full self mode. Further, the operation mode may be changed from the double scan mode to the full self mode when the operation by the clerk is stopped in the double scan mode (for example, when a predetermined time has elapsed from the time of the last operation).

(Semi-self mode (accounting-only mode))
In the semi-self mode (accounting-only mode), as shown in Fig. 5 (A), receiving registration information from other terminals, reading accounting tickets, and inserting money are set to valid "○", and product registration (clerk side). This is an operation mode in which the product registration (customer side) is invalidated as "-". That is, the semi-self mode (accounting-only mode) is an operation mode in which the registration process is not executed on the own terminal, but the settlement process is executed exclusively based on the registration information generated on the other terminal. The semi-self mode (accounting-only mode) is a function that receives the registration information generated in the registration process on another terminal and executes the settlement process, and a function that reads the accounting ticket issued on the other terminal and executes the settlement process. including. Since the semi-self mode (accounting-only mode) is an operation mode in which the registration process is not executed (because the registration information is not generated), as shown in FIG. 5 (A), the registration information can also be transmitted to other terminals. Issuance of accounting tickets is also invalid "-".

(Normal mode (restricted mode))
As shown in FIG. 5 (B), the normal mode (restricted mode) is the transmission of registration information and the issuance of a checkout ticket to other terminals, which are valid "○" in the normal mode (standard mode) of FIG. 5 (A). And is invalid "-". That is, the normal mode (restricted mode) is an operation mode in which the function of causing another terminal to execute the settlement process, which is permitted in the normal mode (standard mode), is restricted.

(Semi-self mode (registration-only mode))
In the semi-self mode (registration-only mode), as shown in Fig. 5 (B), product registration (clerk side), transmission of registration information to other terminals, and issuance of checkout tickets are valid "○", and product registration (product registration) This is an operation mode in which the customer side), the insertion of money, the reception of registration information from other terminals, and the reading of the checkout ticket are disabled as "-". That is, the semi-self mode (registration-only mode) is an operation mode in which the registration process is exclusively executed on the own terminal and the settlement process is executed on the other terminal. Since the semi-self mode (registration-only mode) is premised on the registration operation by the clerk, the product registration (customer side) is invalidated as "-". The semi-self mode (registration-only mode) is a function of transmitting the registration information generated in the registration process to another terminal and causing the other terminal to execute the settlement process, among the functions of the above-mentioned normal mode (standard mode), and the registration. The semi-self mode (registration-only mode) is a function that issues a printed accounting ticket by encoding the registration information (or information for acquiring the registration information) generated in the process and causes the other terminal to execute the settlement process. It also has the function of.

(About enabling / disabling functions)
In the above, the POS terminal 20 has various functions provided by the POS terminal 20 itself (product registration (clerk side), product registration (customer side), money insertion, etc. in FIG. 5 (A), depending on the operation mode. ..., I explained that each of the reading of the accounting ticket) differs depending on whether it is valid "○" or invalid "-". In other words, in the above, the POS terminal 20 originally has all the functions (product registration (clerk side), product registration (customer side), money input, ..., reading of the accounting ticket in FIG. 5 (A)). It has been explained that some of the functions are invalidated according to the operation mode (for example, as shown in FIG. 5A, the POS terminal 20 is a product when it is in the normal mode (standard mode). Registration (customer side) is invalid "-", and when in full self mode, transmission of registration information to other terminals and issuance of accounting tickets are invalid "-").

However, the POS terminal 20 may have different functions that can be executed depending on the operation mode, and the POS terminal 20 does not necessarily have all the functions originally, and some of the functions are invalidated according to the operation mode. It is not necessary to have such a configuration. For example, the POS terminal 20 does not have all the 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). Acquire and execute a program for realizing a function (a function corresponding to a function marked with "○" in FIG. 5) from an external device (for example, a store controller 10, a monitoring terminal, a server outside the store (cloud, etc.)). If there is a program (if it is retained) that enables the operation mode and realizes a function that is unnecessary for the operation mode (a function corresponding to the function that is invalid "-" in FIG. 5), the program is used. It may be in an infeasible state (for example, it may be erased). It should be noted that the program for realizing the necessary function may be acquired and put into the executable state after the program for realizing the unnecessary function is made unexecutable. Further, for example, when switching the operation mode, the POS terminal 20 is for realizing the function required in the operation mode after making all the programs in an unexecutable state regardless of the operation mode of the migration destination. The program may be acquired from the outside and made executable. That is, the configuration of the POS terminal 20 may be such that a part of the various functions originally provided is disabled "-" according to the operation mode, and is necessary depending on the operation mode. It may be such that only various functions are appropriately provided.

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

(Switching of operation mode (transition))
Subsequently, switching (shifting) of the operation mode of the POS terminal 20 will be described. The POS terminal 20 basically switches the operation mode according to an explicit mode switching operation (also referred to as a mode transition operation; details will be described later) for switching the operation mode by the clerk. Further, the POS terminal 20 may switch the operation mode according to another operation (for example, reading a clerk code) different from the mode switching operation.

In addition, the operation mode of the POS terminal 20 may be switched without 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 (POS terminal 20, monitoring terminal, mobile terminal, etc.). In addition, the operation mode of the POS terminal 20 may be switched according to time conditions (for example, the elapsed time since the last operation, the scheduled time according to the schedule, etc.). Further, the POS terminal 20 may switch the operation mode at the start of the process (for example, at the start of the settlement process based on the received registration information, at the start of the settlement process based on the checkout ticket, etc.). Further, the POS terminal 20 may switch the operation mode at the end of the process (for example, at the end of the settlement process based on the received registration information, at the end of the settlement process based on the checkout ticket).

FIG. 9 is a diagram illustrating switching of the operation mode of the POS terminal 20. The left side of FIG. 9 shows a combination of operation modes before and after switching (operation mode before switching → operation mode after switching), and the right side shows conditions for switching operation modes (an example). For example, line a indicates that, as an example of the conditions for switching the operation mode from the normal mode to the full self mode, the mode switching operation, the mode switching command, and the elapse of a predetermined time (not used). That is, when the operation mode is the normal mode, for example, if there is a mode switching operation, a mode switching command, a predetermined time elapse (not used), etc., the operation mode is switched from the normal mode to the full self mode. Shown. The details of the mode switching operation will be described later.

(Normal mode → Full self mode)
As shown in a, when in the normal mode, for example, a mode switching operation, a mode switching command (a mode switching command in which a full self mode is specified as the operation mode of the transition destination, etc.), a predetermined time elapsed (a predetermined time) (Not used), etc., the operation mode is switched 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 was a mode switching operation, a mode switching command (a mode switching command in which a semi-self mode (accounting-only mode) is specified as an operation mode of the transition destination, etc.). In that case, the operation mode is switched from the normal mode to the semi-self mode (accounting-only mode). Further, in the normal mode, for example, when the registration information is received from another terminal or the checkout ticket is read, the operation mode may be switched from the normal mode to the semi-self mode (accounting-only mode). ..

(Full self mode → normal mode)
As shown in c, when 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, etc.) in the full self mode, for example, The operation mode is switched from full self mode to normal mode.

(Full self mode → Semi self mode (accounting only mode))
As shown in d, when in the full self mode, for example, there are a mode switching operation, a mode switching command (a mode switching command in which a semi-self mode (accounting-only mode) is specified as the operation mode of the transition destination, etc.). In that case, the operation mode is switched from the full self mode to the semi-self mode (accounting-only mode). Also, in the full self mode, for example, when registration information is received from another terminal or when the checkout ticket is read, the operation mode is switched from the full self mode to the semi-self mode (accounting only mode). May be good.

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

If the clerk code is read during the full self mode, the operation mode may always be switched to the double scan mode regardless of the product registration status, or the product registration status may be set. It may be switched to a different operation mode depending on the situation. For example, if the clerk code is read when the product has not been registered yet (that is, when the customer has not registered the product), the full self mode is switched to the normal mode, and the product has already been registered. Even if the clerk code is read while the product is being registered (that is, when the customer is registering the product), the full self mode can be switched 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 was 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, etc.). In that case, the operation mode is switched from the semi-self mode (accounting-only mode) to the normal mode. In addition, in the semi-self mode (accounting-only mode), for example, when the settlement process (for example, the settlement process based on the received registration information, the settlement process based on the accounting ticket) is completed, the semi-self mode (accounting-only mode) ) 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 are a mode switching operation, a mode switching command (a mode switching command in which the full self mode is specified as the operation mode of the transition destination, etc.). In that case, the operation mode is switched from the semi-self mode (accounting-only mode) to the full self mode. In addition, in the semi-self mode (accounting-only mode), for example, when the settlement process (for example, the settlement process based on the received registration information, the settlement process based on the accounting ticket) is completed, the semi-self mode (accounting-only mode) ) May be switched to the full self mode.

The mode switching operation may be performed as long as the operation mode of the migration destination is specified according to the operation. For example, when each button for each migration destination is provided (or displayed), the operation mode may be switched to each migration destination according to the mode switching operation in which each button is pressed. Further, in the case of providing (or displaying) one button whose transition destination is switched each time the button is pressed, the operation mode may be switched each time the mode switching operation is performed by pressing the button.

It should be noted that a button for selecting the operation mode of the transition destination and a button for determining the 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 the clerk (see FIG. 6). Specifically, the mode switching button 211a arranged at the uppermost stage and the rightmost end of the key operation unit 211, the batch switching button 211b arranged on the left side thereof, and the accounting-dedicated mode switching button 211c arranged further on the left side thereof ( The operation mode is switched according to the operation shown in FIG. 3B).

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

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

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

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

Further, the operation by the batch switching button 211b may always be effective, or may be effective in the specific POS terminal 20. For example, a batch switching button 211b is arranged on a specific POS terminal 20 (for example, a POS terminal 20 (POS terminal 20 arranged at a certain place) frequently used by a store manager or the like, and a POS that is not a specific POS terminal 20). The batch switching button 211b may not be arranged on the terminal 20. Further, although the batch switching button 211b is arranged on all the POS terminals 20, the specific POS terminal 20 (for example, the POS to which the store manager or the like is logged in) is logged in. When the batch switching button 211b is operated on the terminal 20 or the like), the switching by the above batch method is executed, but when the batch switching button 211b is operated on the POS terminal 20 which is not the specific POS terminal 20. May not be executed by the batch method. The same applies to the operation by the accounting mode switching button 211c (described later).

Similarly, the dedicated button for switching the accounting-only mode for switching to the accounting-only mode may always be valid, or may be valid at the specific POS terminal 20. The mode switching button 211a for switching the operation mode, the batch switching button 211b, the accounting-dedicated mode switching button 211c, and the like are hardware keys, but instead of or in addition to the hardware key, a display unit (clerk side display unit 210) Etc.) may be the software key displayed. That is, the software key corresponding to the mode switching button 211a may be displayed in place of or in addition to the mode switching button 211a, or the software key corresponding to the batch switching button 211b may be displayed in place of or in addition to the batch switching button 211b. May be displayed, or in addition to or in addition to the accounting-dedicated mode switching button 211c, a software key corresponding to the accounting-dedicated mode switching button 211c may be displayed. The same applies to each button when a number of mode switching buttons corresponding to each operation mode are prepared.

When the mode switching button 211a is operated, the process according to the state when the mode switching operation is performed is executed (the operation according to the state when the mode switching operation is performed is performed). , What kind of processing is executed (what kind of operation will be performed) may be notified. The same applies to the case where the batch switching button 211b or the accounting mode switching button 211c is operated. In a mode in which a software key (a software key corresponding to the mode switching button 211a, a software key corresponding to the batch switching button 211b, and a software key corresponding to the accounting-only mode switching button 211c) is used, the mode switching button of the software key is operated. The same applies to the case where.

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

Further, each POS terminal 20 may notify the current operation mode of another terminal in place of or in addition to the current operation mode of the own terminal. That is, each POS terminal 20 may notify the current operation mode of the other terminal by recognizing each other's current operation mode of the other terminal. As an example of the method in which each POS terminal 20 recognizes the current operation mode of another terminal, each POS terminal 20 notifies the other terminal of the operation mode (latest operation mode) after the transition to the operation mode (LAN11). This is a method of directly notifying other terminals via the store controller 10 or notifying other terminals via a store controller 10 or a monitoring terminal). Further, each POS terminal 20 may notify the current processing status of the other terminal as well as the current operation mode of the other terminal.

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

Even if the operation mode is switched by the operation of the clerk (mode switching operation, reading of the clerk code, etc.), the operation mode is switched without the operation of the clerk (mode switching command, predetermined time). Even if it depends on the progress, etc.), the operation mode of the own terminal or another terminal is notified.

(Memory of information about operation mode)
Each POS terminal 20 may store in which operation mode the transaction (processing) is performed as information regarding the operation mode. For example, when the POS terminal 20-1 operating in the normal mode (standard mode) executes the registration process and the settlement process for a certain transaction, the POS terminal 20-1 that has executed the registration process and the settlement process is the transaction. Information (for example, in association with information about the transaction) that the registration process and the settlement process for the transaction were performed in the normal mode (standard mode) (for example, identifying the operation mode). Possible information, etc.) may be stored.

In addition, each POS terminal 20 may also memorize which terminal the transaction (processing) was performed on. In the above example, the POS terminal 20-1 may store information indicating that the registration process and the settlement process have been executed on the own terminal (POS terminal 20-1) as information related to the transaction. 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 executed the registration process, and itself as the terminal identification information of the terminal that has executed the settlement process. 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 executed the entire processing (registration processing, settlement processing).

Further, for example, first, the POS terminal 20-1 operating in the normal mode (standard mode) executes the 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 executed for the transaction based on the registration information by the above registration process, the POS terminal 20-2 that executed the settlement process can be used as information (for example, settlement information) related to the transaction (or the relevant settlement information). (In association with the information related to the transaction), the information that the registration process related to the transaction was performed in the normal mode (standard mode) is stored, and the settlement process related to the transaction is performed in the semi-self mode (accounting-only mode). Information may be stored. Further, in addition to the above, the POS terminal 20-1 that has executed the registration process may also store information that the registration process related to 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 the information that the registration process has been executed in the other terminal (POS terminal 20-1) as the information related to the transaction, and stores the information that the registration process has been executed in the own terminal (POS). Information indicating that the settlement process has been executed at the terminal 20-2) may be stored. More specifically, the POS terminal 20-2 stores the terminal identification information of another terminal (POS terminal 20-1) as the information (terminal identification information) of the terminal that executed the registration process, and the terminal that executed the settlement process. The terminal identification information of the own terminal (POS terminal 20-2) may be stored as the terminal identification information of. In the above example, on the side of the POS terminal 20-2 that executes the settlement process, the terminal identification information and the operation mode (specifically, the normal mode (standard mode)) of the POS terminal 20-1 that executed the registration process are set. It suffices if the information to be identified 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 side of the POS terminal 20-1 to the side of the POS terminal 20-2 (for example, transmission / reception as registration information, payment ticket). It suffices if it is supplied via).

Further, each POS terminal 20 may store the transition (switching) of the operation mode as the information regarding the operation mode. For example, when the operation mode of the POS terminal 20-1 shifts from one operation mode to another, which operation mode the POS terminal 20-1 shifts to together with the transition time of the operation mode. (For example, information that can identify the operation mode after the transition) may be stored. In addition, the POS terminal 20-1 includes information on which operation mode has been shifted from which operation mode to which operation mode has been shifted (for example, information capable of identifying the operation mode before the shift, and the operation mode after the shift). Information that can identify the above, etc.) may be stored.

In addition, even if the operation mode of each POS terminal 20 is switched by the operation by the clerk (when the mode switching operation, the reading of the clerk code, etc.), the operation mode is switched without the operation of the clerk (when the operation mode is switched. Even if it is a mode switching command, a predetermined time elapse, etc.), information regarding 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 changed (for example, the operation mode has been changed by the operation of the clerk of the clerk code "XXX", and the terminal identification information "XX". The operation mode has been changed by the mode switching command from the POS terminal 20 of "x") may be stored.

In addition to or in addition to the POS terminal 20, the store controller 10 or the monitoring terminal may store information regarding the operation mode.

Further, the information regarding the operation mode to be stored as described above may be output (display, transmission, printing, etc.) as necessary. For example, the POS terminal 20 has information that the receipt output in the full self mode has been processed (registration processing, settlement processing) in the full self mode (information in a mode in which only the clerk can recognize the contents, or the customer. Information in a form that can also be recognized) may 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 the operation mode at the time of processing. As an example, when the POS terminal 20 (or the monitoring terminal) inputs a transaction number (information that can identify the transaction) on a predetermined search screen or the like, the POS terminal 20 (or the monitoring terminal) is included in the registration process and the settlement process for the corresponding transaction. For at least one of them, the processed terminal (terminal identification information or the like) and the operation mode (information that can identify the operation mode) may be displayed.

(Situation inside the store where the POS terminal 20 is installed)
FIG. 10 is a perspective view of a plurality of POS terminals 20 installed in the store as viewed from the customer side. FIG. 11 is a schematic sketch of the store. As shown in FIGS. 10 and 11, the first POS terminal 20-1 and the second POS terminal 20-2 are installed as two POS terminals in the store M. As shown in FIGS. 10 and 11, the first POS terminal 20-1 and the second POS terminal 20-2 are the clerk side of the first POS terminal 20-1 and the second POS terminal 20-2, and the first POS terminal 20-1 and the first POS terminal 20-2. The customer side of the 2POS terminal 20-2 is arranged and installed on the same side. Further, as shown in FIGS. 10 and 11, the first counter 21-1 is installed on the right side when viewed from the customer side of the first POS terminal 20-1, and the right side when viewed from the customer side of the second POS terminal 20-1. A second counter 21-2 is installed in.

Both the first POS terminal 20-1 and the second POS terminal 20-2 can be used by switching the operation mode to any one of a normal mode, a full self mode, and a semi-self mode. The first POS terminal 20-1 and the second POS terminal 20-2 can notify the clerk in the store M of the usage status information regarding the usage status of the own terminal according to the respective operation modes (see FIG. 15). Is.

Further, the POS system 1 can be connected to a handy terminal 30 (see FIG. 14) for managing inventory of a store provided with a POS terminal 20 and a monitoring system 40 for monitoring the status of the store. Both the handy terminal 30 and the monitoring system 40 are capable of wireless or wired communication with the POS system 1.

The handy terminal 30 includes a housing 31, and the housing 31 is provided with a display unit 32 and an operation unit 33. Further, inside the housing 31, a CPU as a central processing unit, a ROM, a RAM, a communication unit, etc. as a storage device are provided, and communication with the POS terminal 20 and the monitoring monitor 42 is possible. Has been done.

The handy terminal 30 is mainly a terminal owned and used by a clerk in the store M. The clerk possesses the handy terminal 30 as a mobile terminal and manages the inventory of products in the store M. When performing inventory management or the like, the clerk sees the display displayed on the display unit 32 and operates the operation unit 33. Information necessary for inventory management is displayed on the display unit 32, and usage status information of the POS terminal 20 transmitted from the POS terminal 20 is displayed.

The handy terminal 30 is provided with a speaker and a vibrator (not shown). Of these, it is possible to output a predetermined voice or warning sound according to the usage status information of the POS terminal 20 transmitted from the POS terminal 20 from the speaker. Further, the vibrator vibrates in a pattern corresponding to the usage state information of the POS terminal 20 transmitted from the POS terminal 20. The speaker and the vibrator are controlled by the CPU.

Further, as shown in FIG. 11, a store area M1 and a backyard M2 are provided in the store M. In the store area M1, a first POS terminal 20-1 and a second POS terminal 20-2 are provided, and a display shelf for displaying products and a fixture T1 such as a refrigerator / freezer storage are provided. Further, the backyard M2 is provided with a desk T2 for a clerk or the like to take a break or perform work such as bookkeeping, and a backside fixture T3 such as a storage shelf for storing inventory products. The arithmetic unit 41, the monitoring monitor 42, and the speaker 43 in the monitoring system 40 are mounted on the desk T2.

The arithmetic unit 41 processes the image in the store M captured by an imaging device (not shown) provided at a position where the store area M1 can be photographed, and displays it on the monitoring monitor 42. Further, the arithmetic unit 41 causes the monitoring monitor 42 to display an image corresponding to the usage status information transmitted from the POS terminal 20. The monitoring monitor 42 displays images in the store and usage status information of the POS terminal 20 under the control of the arithmetic unit 41. Further, the arithmetic unit 41 outputs a predetermined alarm to the speaker 43 according to the usage status information transmitted from the POS terminal 20, and notifies the store clerk of the usage mode information. In FIG. 11, some structures such as the entrance door are omitted and simplified as a whole.

In the store M, by switching the operation modes of the two installed POS terminals 20 (the first POS terminal 20-1 and the second POS terminal 20-2), the store clerk in the off-hours, busy hours, etc. of the store M It is possible to optimize the number of staff and the handling of customers. For example, in a quiet time such as midnight, the operation mode of the two POS terminals 20 is set to the full self mode, and the customer can take out the goods and clean the store M without having a clerk at the cash register. Have the product transaction completed by the operation of. Further, during busy hours such as lunch break hours, the operation modes of the two POS terminals 20 are both set to normal modes, and a clerk is assigned to each POS terminal 20 to handle a large number of customers. Further, in a normal time zone such as evening, the operation mode of one POS terminal 20 is a normal mode or a semi-self mode (registration-only mode), and the other POS terminal 20 is a full-self mode or a semi-self mode (accounting-only mode). ), And a clerk is assigned to the POS terminal 20 in the normal mode or the semi-self mode (registration-only mode) to handle customers.

Further, when the POS terminal 20 has a POS terminal 20 in an operation mode operated by the customer, the POS terminal 20 is a customer-side operation unit (customer-side display unit 205, customer-side scanner) that accepts the customer's operation. A process is performed to output usage status information according to the usage status of the unit 206, the card payment unit 208, the change machine 209, hereinafter referred to as "change machine 209, etc.") to the clerk. The operation mode operated by the customer includes a normal mode, a full self mode, and a semi-self mode (accounting-only mode). Among them, in the normal mode, there is a clerk in the vicinity of the POS terminal 20. Therefore, when one POS terminal 20 is in the full self mode and the semi-self mode (accounting-only mode), the POS terminal 20 is a process for outputting the usage status information of the change machine 209 or the like to the clerk. I do.

The notification unit and the notification mode for notifying the usage status information differ depending on the operation mode of the two POS terminals 20. Hereinafter, the operation mode of the POS terminal 20 and the notification mode of the usage state of the change machine 209 and the like according to the operation mode of the POS terminal 20 will be described with reference to specific examples.

In the following, when the first POS terminal 20-1 is in the normal mode and the second POS terminal 20-2 is in the full self mode as an example in the normal time zone, the first POS terminal 20-1 is in the normal mode as another example in the normal time zone. When the second POS terminal 20-2 is in the semi-self mode (accounting-only mode), as an example in the off-hours, when both the first POS terminal 20-1 and the second POS terminal 20-2 are in the full self mode 3 This will be described with reference to two specific examples (examples in the case of the star mark in FIG. 15). In the busy hours, the operation modes of the first POS terminal 20-1 and the second POS terminal 20-2 are both normal modes, and since the clerk is in the vicinity, the usage status information is basically not notified. .. However, the usage status information may be notified even when the operation modes are all normal modes.

(Notification mode of usage status information of change machine 209 or the like when the first POS terminal 20-1 is in the normal mode and the second POS terminal 20-2 is in the full self mode [first mode])
First, the notification mode [first mode] of the usage status information will be described. In a normal time zone other than a quiet time zone or a busy time zone, for example, the operation mode of the first POS terminal 20-1 may be set to the normal mode, and the operation mode of the second POS terminal 20-2 may be set to the full self mode. In this case, the clerk operates the first POS terminal 20-1, but the customer himself performs the operations from registration to settlement of the second POS terminal 20-2.

The second POS terminal 20-2 notifies the clerk who operates the first POS terminal 20-1 of the usage status information. Specifically, the second POS terminal 20-2 displays non-use information (one of the usage status information) on the clerk side display unit 210 of the own terminal when the time when the own terminal is not used elapses for a predetermined time. To display. That is, the clerk-side display unit 210 of the second POS terminal 20-2 serves as a notification unit for notifying the usage status information. It should be noted that the second POS terminal 20-2 provides no usage information when the first POS terminal 20-1 is not used by a clerk even when the time when the own terminal is not used has elapsed. It may not be displayed.

As shown in FIG. 12 (A), the second POS terminal 20-2 is the first POS terminal 20-1 side (in the example of FIG. 12 (A)) of the display area (display screen) of the clerk side display unit 210 of the own terminal. A small screen (small window) SG01 is displayed at the end of (right side). The first information display frame JH01 to the fifth information display frame JH05 are displayed on the small screen SG01. Of these, the first information display frame JH01 is "not used", the second information display frame JH02 is "product registration", the third information display frame JH03 is "registration completed", and the fourth information display frame JH04 is "not used". Each character of "receipt" is displayed in "cash insertion" and the fifth information display frame JH05. In addition, the second POS terminal 20-2 darkly displays the first information display frame JH01 to the fifth information display frame JH05 as the display of the corresponding usage status information. In the example shown in FIG. 12 (A), since the second POS terminal 20-2 is not used, "not used" is blacked out in the first information display frame JH01 as a display of no use information. As the background of the small screen SG01, for example, a screen common to the screen displayed on the customer side display unit 205 is displayed. Alternatively, another screen may be displayed.

When the customer starts using the second POS terminal 20-2, specifically, when the product registration is started on the second POS terminal 20-2 in the full self mode, the second POS terminal 20-2 , Display usage start information as usage status information. After that, the second POS terminal 20-2 displays according to each usage state information according to the use of the customer.

Specifically, when the customer registers the product by the registration device on the customer side, as shown in FIG. 12B, the second information display frame JH02 is darkened to display the product registration information. indicate. Further, along with the darkening display of the second information display frame JH02, the darkening display of the first information display frame JH01 is displayed brightly. Similarly, when the customer operates the registration completion key, the registration completion information is displayed by dimming the third information display frame JH03, and when the customer inserts cash into the change machine 209, the fourth information display frame is displayed. By dimming JH04, cash input information is displayed. Then, when the customer receives the receipt, the receipt receipt information is displayed by darkening the fifth information display frame JH05.

(Notification mode of usage status information of change machine 209 or the like when the first POS terminal 20-1 is in the normal mode and the second POS terminal 20-2 is in the semi-self mode (accounting-only mode) [second mode])
Next, a mode of notifying the usage status information [second mode] will be described. In normal time zones other than off-peak hours and busy hours, for example, the operation mode of the first POS terminal 20-1 may be set to the normal mode, and the operation mode of the second POS terminal 20-2 may be set to the semi-self mode (accounting-only mode). is there. In this case, the clerk operates the first POS terminal 20-1, but the customer himself operates the second POS terminal 20-2 for accounting.

The second POS terminal 20-2 notifies the clerk who operates the first POS terminal 20-1 of the usage status information. Specifically, the second POS terminal 20-2 is shown in FIG. 13 (A) as non-use information (one of the usage status information) when the time when the own terminal is not used has elapsed for a predetermined time. As described above, the small screen (small window) SG02 is displayed on the clerk side display unit 210 of the own terminal. That is, the clerk-side display unit 210 of the second POS terminal 20-2 serves as a notification unit for notifying the usage status information. By displaying the small screen SG02, the clerk who operates the first POS terminal 20-1 is notified that the own terminal (second POS terminal 20-2) is inactive.

Subsequently, when the customer starts using the second POS terminal 20-2, specifically, when the settlement process is started based on the registration information transmitted from the first POS terminal 20-1, the first The 2POS terminal 20-2 displays usage start information as usage status information. After that, the second POS terminal 20-2 displays according to each usage state information according to the use of the customer.

When the settlement process is started, the second POS terminal 20-2 has a display area (display screen) of the clerk side display unit 210 of the own terminal on the first POS terminal 20-1 side (display screen) as shown in FIG. 13 (B). A small screen (small window) SG03 is displayed at the end (on the right side in the example of FIG. 12A). The first information display frame JH01 to the fifth information display frame JH05 are displayed on the small screen SG03. Of these, the first information display frame JH01 is "cash input", the second information display frame JH02 is "accounting completed", the third information display frame JH03 is "change receipt", and the fourth information display frame JH04 is "change receipt". Each character of "no operation" is displayed on the "receipt" and the fifth information display frame JH05. In addition, the second POS terminal 20-2 darkly displays the first information display frame JH01 to the fifth information display frame JH05 as the display of the corresponding usage status information.

Specifically, when the customer inserts cash, the second POS terminal 20-2 darkens the first information display frame JH01 and displays the cash insertion information as shown in FIG. 13 (B). Further, when the customer operates the registration completion key to complete the registration of the product, the second POS terminal 20-2 darkens the second information display frame JH02 and displays the registration completion information. When the customer receives the change, the second POS terminal 20-2 darkly displays the third information display frame JH03 to display the change receipt information. When the customer receives the receipt, the second POS terminal 20-2 darkens the fourth information display frame JH04 and displays the receipt receipt information. Further, when the customer does not perform the operation for a predetermined time after starting the settlement process, the second POS terminal 20-2 darkly displays the fifth information display frame JH05 to display no operation information.

Of these, when no operation information is displayed, the customer has started the registration operation by the second POS terminal 20-2, but since there is no operation after that, the customer is at a loss (problem) in the registration operation. Expected to be in a state. Therefore, it is possible to urge the clerk who operates the first POS terminal 20-1 to support the customer who operates the second POS terminal 20-2.

When the second POS terminal 20-2 darkens one information display frame, the other information display frame that has been darkened is turned bright, but even if a plurality of information display frames are darkened. Good. In addition, the mode of information display may be a method other than dark display. For example, the information display frame and the characters in the information display frame may be illuminated, enlarged, or changed to a different color.

In the above examples of [1st aspect] and [2nd aspect], the second POS terminal 20-2 may display the small screen SG01, the small screen SG02, etc. when the predetermined conditions are satisfied. For example, a motion sensor is provided on the clerk side of the own terminal (second POS terminal 20-2) (for example, the clerk side and the first POS terminal 20-1 side) or the clerk side of the first POS terminal 20-1. The small screen SG01, the small screen SG02, etc. may be displayed on condition that it is detected that the clerk is on the clerk side of the 1POS terminal 20-1.

Further, in the above [first aspect] and [second aspect] examples, the first POS terminal 20-1 side (right side in the example of FIG. 12A) of the display area (display screen) of the second POS terminal 20-2. The usage status information is displayed at the end of), but it may be displayed at another position as long as it is easy for the clerk who operates the first POS terminal 20-1 to see. For example, the usage mode information may be displayed on the clerk side display unit 210 of the first POS terminal 20-1. Further, for example, a display device (use) that displays usage status information on the clerk side of the first POS terminal 20-1 and the clerk side of the second POS terminal 20-2 (for example, the clerk side and the first POS terminal 20-1 side). A mode information display device) may be provided separately. The usage mode information display device may be, for example, an image display device such as a liquid crystal monitor, or a lamp for lighting a warning lamp or the like.

(Notification mode of usage status information of change machine 209 or the like when both the first POS terminal 20-1 and the second POS terminal 20-2 are in the full self mode [third mode])
Subsequently, the notification mode [third mode] of the usage status information will be described. In off-hours such as midnight, both the first POS terminal 20-1 and the second POS terminal 20-2 are in full self mode, and there are often no clerk in the vicinity of the POS terminal 20. In this case, both the first POS terminal 20-1 and the second POS terminal 20-2 transmit the usage status information to the handy terminal 30 owned by the clerk. In this example, the display unit 32 of the handy terminal 30 serves as the notification unit.

Specifically, the POS terminal 20 does not transmit the usage status information when the own terminal is not used, but is not used each time when the time when the own terminal is not used elapses. The information is transmitted to the handy terminal 30. For example, when the predetermined time is set to 30 minutes, the POS terminal 20 transmits the non-use information to the handy terminal 30 every 30 minutes when the own terminal is not used.

The handy terminal 30 that has received the non-use information performs notification according to the non-use information. FIG. 14A is a display example of the handy terminal. As a notification according to the non-use information, for example, as shown in FIG. 14 (A), a message image MG01 in which characters such as "No. 0 cash register is not used" is displayed on the display unit 32 of the handy terminal 30. Or, the speaker outputs a voice such as "No cash register is used", or the vibrator is vibrated in a set pattern corresponding to no information. The handy terminal 30 may perform one of these notifications, or may perform a plurality of notifications among them. Alternatively, the output mode may be changed according to the usage status of the handy terminal 30. For example, when the screen used for inventory management is displayed by the handy terminal 30, the display on the display unit 32 may be stopped or the display may be displayed in a small window (small window). Further, the mode of notification may be changed by setting the clerk who owns the handy terminal 30. For example, when the speaker is turned off, the display on the display unit 32 may be increased or the vibration of the vibrator may be increased as compared with the case where the speaker is turned on.

When the customer starts using the POS terminal 20, the POS terminal 20 transmits the usage start information to the handy terminal 30 as the usage status information. The POS terminal 20 uses the POS terminal 20 when the customer side display unit 205 is touched, when a bar code or the like is read by the customer side scanner unit 206, or when cash is inserted into the change machine 209. Is determined to have started and the usage status information is transmitted.

The handy terminal 30 that has received the usage status information displays a message corresponding to the transmitted usage start information on the display unit 32 or outputs the message from the speaker, as in the case of receiving the usage non-information. Alternatively, the vibrator is vibrated in a pattern set in response to the usage start signal. The handy terminal 30 may perform one of these notifications, or may perform a plurality of notifications among them. Alternatively, the mode of notification may be changed according to the usage status of the handy terminal 30.

Subsequently, the customer registers the product on the POS terminal 20, and when the product registration is completed, operates the registration completion key to complete the product registration. After that, the transaction is completed by inserting cash into the change machine 209 or receiving change or receipt. The POS terminal 20 from the transaction of the product to the checkout transmits the usage status information according to the operation of the clerk to the handy terminal 30. For example, when the product is registered, the product registration information is transmitted, and when the registration completion key is operated, the registration completion information is transmitted. Further, when cash is inserted into the change machine 209, the cash insertion information is transmitted, and when the receipt is received, the receipt receipt information is transmitted.

The handy terminal 30 that has received the product registration information, registration completion information, cash insertion information, receipt receipt information, and the like is notified according to the received usage status information. For example, when the product registration information is received, a display such as "Product registration" is displayed on the display unit 32, a voice such as "Product registration is being registered" is output from the speaker, or the product registration information is received. The vibrator is vibrated according to the pattern set according to.

Further, these usage status information may be transmitted to the monitoring system 40 provided in the backyard M2, and the monitoring system 40 may notify the usage status information of the POS terminal 20. FIG. 14B is a display example of the monitoring monitor. For example, when the usage non-use information is transmitted as the usage status information, the monitoring system 40 displays a message image MG02 such as "No. 0 cash register not used" on the monitoring monitor 42 as shown in FIG. 14 (B). Alternatively, the speaker 43 shown in FIG. 11 may output a voice such as "No cash register is used". In addition, with or instead of a specific message, a display indicating that no usage information has been received, for example, blinking or blinking of the entire or part of the screen, increase in brightness, brightness, color change, etc. may be performed. Alternatively, a warning sound may be output from the speaker 43. These outputs may be performed in the handy terminal 30.

FIG. 15 is a diagram showing the relationship between the operation mode of the POS terminal and the notification mode of the usage mode state of the second POS terminal. In FIG. 15, “☆” represents a mode of notification of usage status information in the above three specific examples. That is, in FIG. 15, the [first aspect] in the column specified from the column “normal” of the first POS terminal 20-1 and the row “full self” of the second POS terminal 20-2 is the first POS terminal 20-1. It shows that the usage state information in the normal mode and the second POS terminal 20-2 in the full self mode is [first mode]. In the [second mode] in the column specified from the column "normal" of the first POS terminal 20-1 and the row "accounting only" of the second POS terminal 20-2, the first POS terminal 20-1 is in the normal mode and the second POS is the second POS. It indicates that the usage status information when the terminal 20-2 is in the semi-self mode (accounting-only mode) is the [second mode]. The [third aspect] in the column specified from the column "full self" of the first POS terminal 20-1 and the row "full self" of the second POS terminal 20-2 is the first POS terminal 20-1 and the second POS terminal 20-2. It shows that the usage state information in the case where all of the above are in the full self mode is [third mode].

FIG. 15 also shows a mode of notifying the usage state information in the case of combinations other than the above three as the operation modes of the first POS terminal 20-1 and the second POS terminal 20-2.

In FIG. 15, [No output] in the column specified from the column “normal” of the first POS terminal 20-1 and the row “normal” of the second POS terminal 20-2 is also the second POS of the first POS terminal 20-1. Since the terminal 20-2 also has a clerk, it indicates that the usage status information is not output. The same applies to [No output] in the other columns.

Further, in FIG. 15, [(first aspect)] in the column specified from the column “full self” of the first POS terminal 20-1 and the row “normal” of the second POS terminal 20-2 is the first in which no clerk exists. Since the 1POS terminal 20-1 notifies the clerk of the 2nd POS terminal 20-2, the 2nd POS terminal 20-2 side of the display area (display screen) of the clerk side display unit 210 of the own terminal (1st POS terminal 20-1). It indicates that a small screen (small window) SG01 is displayed at the end of (the side where the clerk exists). The same applies to [(first aspect)] in the column specified from the column “full self” of the first POS terminal 20-1 and the row “registration only” of the second POS terminal 20-2.

Further, in FIG. 15, [(second aspect)] in the column specified from the column “accounting only” of the first POS terminal 20-1 and the row “normal” of the second POS terminal 20-2 does not have a clerk. Since the first POS terminal 20-1 notifies the clerk of the second POS terminal 20-2, the second POS terminal 20-2 in the display area (display screen) of the clerk side display unit 210 of the own terminal (first POS terminal 20-1). It indicates that a small screen (small window) SG02 is displayed at the end of the side (the side where the clerk is present). The same applies to [(second aspect)] in the column specified from the column “accounting only” of the first POS terminal 20-1 and the row “registration only” of the second POS terminal 20-2.

Since neither the first POS terminal 20-1 nor the second POS terminal 20-2 is basically set to the semi-self mode (accounting-only mode), the column "accounting-only" of the first POS terminal 20-1 is used. The column specified from the line "Accounting only" of the second POS terminal 20-2 is set to [No setting]. Further, since neither the first POS terminal 20-1 nor the second POS terminal 20-2 is basically set to the semi-self mode (registration-only mode), the column "registration-only" of the first POS terminal 20-1 is used. The column specified from the line "Registration only" of the second POS terminal 20-2 is set to [No setting].

As shown in FIG. 15, when the operation mode of the second POS terminal 20-2 is the normal mode or the semi-self mode (registration-only mode), the second POS terminal 20 is irrespective of the operation mode of the first POS terminal 20-1. Usage mode information is not notified from -2. This is because the clerk actually exists in the second POS terminal 20-2, which is the own terminal, regardless of whether or not the clerk exists in the first POS terminal 20-1 which is another terminal.

Further, when the operation mode of the second POS terminal 20-2 is the full self mode, when the operation mode of the first POS terminal 20-1 is the normal mode or the semi-self mode (registration-only mode), the notification is performed by the first mode. When the operation mode of the first POS terminal 20-1 is the full self mode or the semi-self mode (accounting-only mode), the notification is performed according to the third aspect.

Further, when the operation mode of the second POS terminal 20-2 is the semi-self mode (accounting-only mode), the second operation mode of the first POS terminal 20-1 is the normal mode or the semi-self mode (registration-only mode). The notification is based on the mode, and when the operation mode of the first POS terminal 20-1 is the full self mode, the notification is based on the third mode.

In the POS terminal 20, when the clerk side display unit 210 and the customer side display unit 205 can be installed apart from each other, the clerk side display unit 210 may be arranged at a position where the clerk on the other side can easily see. However, it may be arranged at an angle that is easy for the clerk on the other side to see.

Although the above POS system 1 has been described, according to the POS system 1, it is possible to smoothly carry out transactions and prevent fraud at a cash register operated by a customer.

For example, in the second POS terminal 20-2 where the clerk is not nearby, when the customer registers and pays by himself / herself, the customer is confused because he / she does not know how to operate or the second POS terminal 20-2 does not operate as desired. It is conceivable to do. In this case, the customer can easily continue the processing on the second POS terminal 20-2 with the support of the clerk, etc., but if there is no clerk nearby, he / she may not have such an expectation. .. Further, since there is no clerk near the second POS terminal 20-2, even if the customer who operates the second POS terminal 20-2 commits a fraud, it becomes difficult to detect the fraud.

On the other hand, in the above-mentioned POS system 1, the usage status information in the second POS terminal 20-2 is notified to the clerk who operates the first POS terminal 20-1 or the clerk in the store. Therefore, the clerk can know the usage state of the second POS terminal 20-2 even when the operation mode is not in the vicinity of the second POS terminal 20-2 such as the full self mode. Therefore, the clerk who knows that the customer is having trouble in operation can move to the vicinity of the second POS terminal 20-2 and support the customer. In addition, the clerk operating the first POS terminal 20-1 can support the operation of the second POS terminal 20-2 between the operations of the first POS terminal 20-1. In addition, when recognizing a customer who intends to cheat, the clerk can move to the second POS terminal 20-2 and perform an act such as listening to the customer. Therefore, at the cash register operated by the customer, transactions can be smoothly performed and fraud can be prevented.

Further, the first POS terminal 20-1 is provided with a customer-side operation unit of its own terminal on the side of the customer-side operation unit of the second POS terminal 20-2, and in the own terminal, a clerk is located at a position facing the customer-side operation unit. A side operation unit is provided. Therefore, the clerk who operates the first POS terminal 20-1 is located on the side of the second POS terminal 20-2, so that the second POS terminal 20-2 becomes the clerk who operates the first POS terminal 20-1. On the other hand, the usage status information can be preferably notified. Therefore, the clerk who operates the first POS terminal 20-1 can easily support the customer and prevent fraud at the second POS terminal 20-2.

Further, also in the second POS terminal 20-2, as in the case of the first POS terminal 20-1, a clerk side operation unit is provided at a position facing the customer side operation unit in the own terminal. Therefore, by linking the first POS terminal 20-1 and the second POS terminal 20-2, it is possible to improve the efficiency of customer handling during the busy hours and contribute to the suppression of surplus personnel during the off-hours.

Further, in the second POS terminal 20-2, the usage mode information of the own terminal is displayed on the left side (first POS terminal 20-1 side) of the clerk side display unit 210. Therefore, the second POS terminal 20-2 can suitably notify the clerk who operates the first POS terminal 20-1 of the usage status information, so that the clerk who operates the first POS terminal 20-1 is the second POS terminal. The usage status information displayed on the store clerk side display unit 210 of 20-2 can be easily visually recognized. Therefore, it is possible to easily support customers and prevent fraud in the second POS terminal 20-2 while improving efficiency and suppressing surplus personnel.

In addition, during off-hours such as midnight, the number of visitors is small, so even if a clerk is assigned to the cash register, there will be more time when the clerk does not have work to do, resulting in surplus personnel and adversely affecting store management. Sometimes. In such a case, for example, the operation modes of the first POS terminal 20-1 and the second POS terminal 20-2 are both set to the full self mode, and the customer himself performs the processing from product registration to settlement, and the clerk is in the store. It is possible to contribute to the efficiency of management by performing behind-the-scenes work such as cleaning, stocking, and inventory management.

However, in the POS terminal 20 whose operation mode is the full self mode, when the clerk is busy with the operation, the POS terminal 20 transmits the usage status information of the POS terminal 20 to the handy terminal 30 and the monitoring system 40, which is handy. The usage status information is displayed on the display unit 32 of the terminal 30 and the monitoring monitor 42 of the monitoring system 40. Therefore, the clerk can move to the vicinity of the POS terminal and support the customer. Further, even if the customer intends to cheat on the POS terminal 20, the clerk can move to the POS terminal and perform an act such as listening to the customer. Therefore, at the cash register operated by the customer, transactions can be smoothly performed and fraud can be prevented.

In the above example, as the output mode of the usage status information, a mode of displaying on the clerk side display unit 210 of the own terminal, a mode of displaying on the display unit of the handy terminal 30 or the monitoring monitor of the monitoring system 40, or a voice from a speaker or the like. Although the output mode is used, other modes may be used. For example, as an output unit for outputting usage status information, a display unit such as a store clerk side display unit 210 or a speaker, or a so-called barber's pole may be used.

As the barber's pole, for example, a barber's pole that lights and blinks a plurality of lamps having different colors may be used. When outputting usage status information using such a barber's pole, colors and blinking patterns (including lighting) corresponding to the usage status information are associated with each other, and the lights and blinking patterns are used. The status information may be displayed. Further, the barber's pole may be attached to the POS terminal 20, may be provided at a position away from the POS terminal, for example, at a counter next to the POS terminal 20, and may be provided in the store area M1 and the store area M1 in the store. It may be provided in at least one of the backyards M2.

Further, as in the above [first aspect] and [second aspect], when the usage mode state is output from the speaker from the second POS terminal 20-2 to the first POS terminal 20-1, the registered information is used. The product registration sound may be output when the customer registers the product. In this case, the registration sound when the clerk registers at the first POS terminal 20-1 and the registration sound when the customer registers at the second POS terminal 20-2 may be different. As described above, since the registered sounds are different, the clerk who operates the first POS terminal 20-1 can easily distinguish the registered sound in the second POS terminal 20-2 from the registered sound in the first POS terminal 20-1.

Further, when the usage status information is output by sound from the speakers provided in the POS terminal 20, the handy terminal 30, and the monitoring system 40, the usage status information is associated with the sound output from the speaker, and the speaker is used. The usage status information may be discriminated according to the type of sound output from. For example, different sounds (sound length, pitch, loudness, type, etc.) may be output from the non-use information and the registered information. Further, depending on the characteristics of the usage status information, a common sound may be output for some types of usage status information. For example, a common sound may be output as the registration information and the registration completion information. Further, the usage mode information may be displayed by appropriately combining the above various output patterns. When appropriately combining various output patterns, it may be a combination of only one device or a combination of a plurality of devices.

For example, the registered information may be displayed on the clerk side display unit 210 of the POS terminal 20 and the display unit 32 of the handy terminal 30, the characters may be darkened on the clerk side display unit 210, and the characters may be displayed on the display unit 32 of the handy terminal 30. Good. Further, the character may be darkened on the display unit 210 on the clerk side, and the voice may be output from the speaker on the handy terminal 30.

Further, in the above example, the POS terminal 20 capable of switching the operation mode is taken as an example of the device for outputting the usage status information, but the device such as the POS terminal whose operation mode cannot be switched (the operation mode is not set). It may be. For example, it may be a full-self-type POS terminal in which the customer registers and makes a payment, or it may be a payment machine that makes a payment for a product registered in another POS terminal. Registration information may be transmitted from another POS terminal to this payment machine by wire or wirelessly, or may be transmitted via a store controller or the like. In addition, the registration information may be provided by the above-mentioned accounting ticket or the like.

Further, the usage status information may include information other than the above example. As another example of the usage status information, for example, a near-end state in which the change of the change machine 209 is equal to or less than a predetermined lower limit value, and conversely, a near-full state in which the change of the change machine 209 is equal to or more than a predetermined upper limit value. It may be a state where the receipt paper for printing the issued receipt is about to run out, or another error state.

Although the first embodiment has been described above, according to the first embodiment, a cash register having a plurality of operation modes can be preferably used. For example, it is possible to carry out transactions smoothly and prevent fraud.

For example, at a cash register operated by a customer, a clerk may not be nearby, but if the customer cannot operate the cash register well, the transaction may be delayed. In addition, there is a concern that cheating will be carried out because the clerk is not nearby. According to the technique shown by the first embodiment, it is possible to smoothly carry out the transaction and prevent fraud.

(Second Embodiment)
In the POS system 1 (FIG. 1), the POS terminal 20 recommended to be used is determined (selected) based on the situation of each POS terminal 20 (POS terminal 20-1, POS terminal 20-2, POS terminal 20-3). ) And notify (present) to the clerk. In the following description, the POS terminal 20 recommended for use may be referred to as a recommended cash register.

First, as the situation of each cash register, an outline will be explained using an example focusing only on change. In a store, for example, when there is a cash register with sufficient change and a cash register with insufficient change, when a cash register with sufficient change is selected and customer service is continued, and a cash register with insufficient change is selected. It is more likely that the latter will require replenishment of change in a relatively short period of time, compared to when the customer service is continued. As for the status of each cash register, based on the status of change at each cash register (near end, etc.), the cash register with sufficient change is notified to the clerk as the recommended cash register, and if the clerk uses the recommended cash register, it will take a relatively short time. It is possible to reduce the possibility that change will need to be replenished in the meantime.

FIG. 16 is a diagram illustrating determination of a POS terminal. FIG. 16A shows three POS terminals 20 installed in the store. In FIG. 16A, the counter and the like are not shown. FIG. 16B is an explanatory diagram for conceptually explaining the determination of the recommended cash register and the like. FIG. 16B exemplifies cash, an error, a promotional item, a hot snack, a layout, and an operation mode as a situation when determining a recommended cash register from the three POS terminals 20 shown in FIG. 16A. doing.

In FIG. 16B, line a shows the relationship between the status “cash (change)” of each POS terminal 20 and the recommended cash register based on the status “cash (change)”. In this example, the POS terminal 20-1 has a small amount of 500-yen coins, the POS terminal 20-2 has no problem (there is no problem with any denomination), and the POS terminal 20-3 has a small amount of 1000 yen. Since the number of bills is small, the recommended cash register is POS terminal 20-2. That is, it is recommended that the POS terminal 20, which is less likely to run out of change, be preferentially used by the clerk. As a result, it is possible to reduce the possibility that change will run out during customer service (during transaction).

The small number of 500-yen coins may be the case where the 500-yen coin is near-end, or the case where the 500-yen coin is not near-end but is close to the near-end. For example, if 9 or less coins are managed as near-end for 500-yen coins, and if the number of 500-yen coins is 9 or less, it may be judged that the number of recommended cashiers is small. When the number of coins is 14 or less, it may be judged that the number of recommended cash registers is small. The same applies to other denominations.

In addition to the small amount of cash, the recommended cash register may be decided by paying attention to the large amount of cash. This is because when the amount of cash is small, it is necessary to move (replenish) the cash from the backyard or the like, but when the amount of cash is large, it is necessary to move (store) the cash to the backyard or the like. For example, the POS terminal 20-1 has a large number of 1000-yen bills, the POS terminal 20-2 has no problem (no denomination is small or large, and there is no problem), and the POS terminal 20-3 is 5,000 yen. If there are a lot of bills, the recommended cash register is POS terminal 20-2. In addition, the case where the 1000-yen bill is large may be the case where the 1000-yen bill is near-full, or the case where the 1000-yen bill is not near-full but is close to near-full. The same applies to other denominations.

Instead of the above, paying attention to the total amount, the POS terminal 20-2 that holds the most cash (change) may be used as the recommended cash register. For example, if the holding amount of the POS terminal 20-1 is 205036 yen, the holding amount of the POS terminal 20-2 is 158607 yen, and the holding amount of the POS terminal 20-3 is 418230 yen, the recommended cash register is the POS terminal. It becomes 20-3.

In FIG. 16B, line b shows the relationship between the status “error” of each POS terminal 20 and the recommended cash register based on the status “error”. In this example, the POS terminal 20-1 has two communication failures, the POS terminal 20-2 has no error, and the POS terminal 20-3 has one jamming of the fishing ticket machine. Therefore, the recommended cash register is the POS terminal 20. It becomes -2. That is, the number and types of errors that have occurred (for example, in the last 24 hours) are stored as error information, and the POS terminal 20 that is least likely to generate an error based on the error information is given priority to the clerk. Recommended to use. As a result, it is possible to reduce the possibility that an error will occur when serving customers.

In FIG. 16B, line c shows the relationship between the status “promotional product” of each POS terminal 20 and the recommended cash register based on the status “promotional product”. In this example, the POS terminal 20-1 has no promotional items in the vicinity, the POS terminal 20-2 has a large number of promotional items in the vicinity, and the POS terminal 20-3 has a small number of promotional items in the vicinity. Is the POS terminal 20-2. In other words, products can be displayed around the cash register, and promotional items (for example, special sale items, products just before the deadline, new products, etc. that you want to actively sell) can be sold around the cash register, so it is close to promotional items. It is recommended that the POS terminal 20 be preferentially used by the clerk. As a result, it is possible to increase the chances that the promotional item is visible to the customer and increase the possibility that the promotional item will be purchased.

In FIG. 16B, line d shows the relationship between the status “hot snack” of each POS terminal 20 and the recommended cash register based on the status “hot snack”. In this example, the POS terminal 20-1 has a large number of hot snacks in the vicinity, the POS terminal 20-2 has a small number of hot snacks in the vicinity, and the POS terminal 20-3 has no hot snacks in the vicinity. Is the POS terminal 20-1. That is, since hot snacks (for example, in-store cooked products such as fried chicken, meat buns, and oden) can be sold around the cash register, it is recommended that the POS terminal 20 close to the hot snack be preferentially used by the clerk. This increases the chances that the hot snacks will be seen by the customer, and since the distance between the clerk and the hot snacks is not long, it is easy to place an order, and the possibility of purchasing promotional items can be increased. In addition, since the distance between the clerk and the hot snack is not long, the clerk who received the order can take out the ordered product without a large movement, so the burden is relatively small.

Although omitted in FIG. 16B for simplification, it may be managed for each individual hot snack. For example, the POS terminal 20-1 is managed so that the meat bun is near, the POS terminal 20-2 is near the fried chicken, and the POS terminal 20-3 is near the oden, so that one or more products can be used. You may pay attention and decide the recommended cash register. For example, if you pay attention to meat buns, the recommended cash register is POS terminal 20-1, if it is fried, the recommended cash register is POS terminal 20-2, and if it is oden, the recommended cash register is POS terminal 20-3.

In general, hot snack fixtures are cleaned at midnight, so hot snacks will be discontinued at midnight. In addition, the selling points of hot snacks change depending on the season. Therefore, the recommended cash register will be different depending on the date and time (time zone, month and day). In addition, since the selling points may change depending on the climate (weather, temperature, humidity), the recommended cash register may be different depending on the climate.

In FIG. 16B, the row e shows the relationship between the status “layout” of each POS terminal 20 and the recommended cash register based on the status “layout”. In this example, the POS terminal 20-1 is near the doorway, the POS terminal 20-2 is near the counter break, and the POS terminal 20-3 is near the backyard.

If the ease of traffic between the sales floor and the cash register is of the utmost importance, the recommended cash register is the POS terminal 20-2. That is, in the case of a layout in which the sales floor and the clerk side of the POS terminal 20 are separated by a counter, and the clerk goes back and forth between the sales floor side and the clerk side of the POS terminal 20 through the break of the counter. Since the distance traveled closer to the cut is the shortest in traffic, it is recommended that the POS terminal 20 near the cut of the counter be preferentially used by the clerk. This makes it more efficient and at the same time reduces the burden on the clerk.

If the ease of traffic between the backyard (office) and the cash register is of the utmost importance, the recommended cash register is the POS terminal 20-3.

If the effect on crime prevention is most important, the recommended cash register is POS terminal 20-1. In other words, if a clerk is placed near the entrance and exit of the store, it can exert a certain effect on crime (psychologically keep the person who plans shoplifting away from entering the store, and also deter the shoplifting when leaving the store. Therefore, it is recommended that the POS terminal 20 near the doorway be preferentially used by the clerk. This can contribute to crime prevention.

In general, the delivery schedule and the work schedule of the clerk are predetermined, so the recommended cash register may be determined according to the date and time. For example, the POS terminal 20 near the break of the counter may be recommended during the time when the customer often leaves the cash register for inspection or delivery. In addition, the recommended cash register may be determined by grasping the time zone where crime is likely to occur (season, day of the week, time, etc.) and taking into consideration the time zone where crime is likely to occur in place of or in addition to the above schedule. .. For example, when giving priority to the ease of traffic between the ease of traffic and crime prevention, the POS terminal 20 near the break of the counter, which is easy to come and go even during times when crime is likely to occur. If crime prevention is prioritized between ease of traffic and crime prevention, a doorway that contributes to crime prevention even during times when people often leave the cash register for inspections and product delivery. A nearby POS terminal 20 is recommended.

In FIG. 16B, the row f shows the relationship between the status “operation mode” of each POS terminal 20 and the recommended cash register based on the status “operation mode”. In this example, the operation mode of the POS terminal 20-1 is the full self mode, the operation mode of the POS terminal 20-2 is the semi-self mode (registration only mode), and the operation mode of the POS terminal 20-3 is the normal mode. Therefore, assuming a scene called by a customer (a scene called by a customer waiting for registration by a clerk), the recommended cash register is the POS terminal 20-3. That is, since the store clerk immediately executes the registration process without changing the operation mode, it is recommended that the store clerk preferentially use the POS terminal 20 which is the normal mode. As a result, the clerk can immediately execute the registration process without changing the operation mode. Further, since the POS terminal 20 in the full self mode is left open, other customers can also execute the registration process by themselves. In addition, instead of the POS terminal 20-3 which is the normal mode, the POS terminal 20-2 which is the semi-self mode (registration-only mode) may be used as the recommended cash register, but since it is assumed that the customer is called ( (In order to avoid having the customer wait and then move to another terminal), we recommend the POS terminal 20-3 in the normal mode, which allows the payment process to be performed by the device.

In addition, when assuming other scenes instead of the scene called by the customer (the scene called by the customer waiting for registration by the clerk), the recommended cash register is according to the assumed scene. For example, in a situation where there are many clerk and customers, it is important to handle customers, so the POS terminal 20-1 which is a full self mode may be used as a recommended cash register. Therefore, for example, which operation mode of the POS terminal 20 is recommended may be different depending on the time zone or the like.

In FIG. 16B, the line g is a comprehensive based on the above-mentioned plurality of situations (“cash (change)”, “error”, “promotional item”, ..., “operation mode”) of each POS terminal 20. Recommended cash register is shown. In the example shown in FIG. 16B, the POS terminal 20-2 is recommended as the optimum POS terminal 20 in consideration of a plurality of situations. For example, individual situations (or individual recommended cash registers based on individual situations) are scored (weighted according to the degree of emphasis), and a comprehensive recommended cash register (final recommended cash register) is determined. To do.

It was explained that the individual recommended cash register according to each situation may differ depending on the time zone, but since each recommended cash register may differ depending on the time zone, naturally, it is comprehensive. The recommended cash register may differ depending on the time of day.

Further, in the above description, it is assumed that none of the three POS terminals 20 (POS terminal 20-1, POS terminal 20-2, POS terminal 20-3) is used by a clerk or the like. If there is a POS terminal 20 already used by a clerk or the like, the recommended cash register is determined from other than the POS terminal 20 used. Specifically, scores and the like are calculated for all POS terminals 20 regardless of whether or not they are used, and the one with the highest score or the like among unused ones is determined as a recommended cash register. Instead of the above, the used cash register may be excluded (for the unused cash register), the score or the like may be calculated, and the one with the highest score or the like may be determined as the recommended cash register.

(The entity that decides the recommended cash register)
The entity that determines the recommended cash register will be explained. The recommended cash register is determined based on the information (recommended condition table described later) that is referred to when determining the recommended cash register, but any device that can refer to the information (recommended condition table) is recommended. You may decide the cash register. For example, the POS terminal 20 may refer to the recommended condition table and determine the recommended cash register. Further, instead of or in addition to the POS terminal 20, the store controller 10 may determine the recommended cash register. Further, instead of or in addition to the above, the monitoring terminal (not shown) may determine the recommended cash register. In addition to or in addition to the above, an externally installed server (headquarters server or cloud server) may determine the recommended cash register. A dedicated device for determining the recommended cash register may be provided.

(Subject to display recommended cash register)
The entity that displays the recommended cash register will be explained. Any device may display the recommended cash register as long as it has a display function (display unit. Display). For example, the POS terminal 20 may display the recommended cash register. Further, if the store controller 10 has a display function, the store controller 10 may display the recommended cash register in place of or in addition to the POS terminal 20. Further, instead of or in addition to the above, a monitoring terminal (not shown) may display a recommended cash register. Alternatively, or in addition to the above, the handy terminal 30 may display the recommended cash register. In addition to or in addition to the above, a mobile terminal (excluding the handy terminal 30; for example, a smartphone) used by the clerk may display the recommended cash register.

Needless to say, the device for determining the recommended cash register and the device for displaying the recommended cash register may be the same device or different devices. As an example, an external server or store controller 10 may determine a recommended cash register, and the POS terminal 20 or smartphone may acquire and display the determination result (information indicating which recommended cash register is) (naturally). , Other combinations are acceptable).

Further, the device to be displayed may be specified. For example, it may be possible to set whether to display on all POS terminals 20 or on some POS terminals 20. The setting itself may be performed by any device. Therefore, for example, each POS terminal 20 may set whether or not to display the recommended cash register on its own terminal, or any POS terminal 20 may set the recommended cash register on all POS terminals 20 including its own terminal. It may be set whether or not to display, or whether or not a device other than the POS terminal 20 (for example, a store controller 10 or the like) displays the recommended cash register on all POS terminals 20 is set. You may.

(Timing to decide the recommended cash register)
The recommended cash register may be determined on a regular basis (at a predetermined time and at a predetermined time interval). For example, the recommended cash register may be determined every 10 minutes during business hours. In addition, instead of or in addition to determining the recommended cash register on a regular basis, the recommended cash register may be determined based on predetermined conditions (excluding temporal ones).

As an example, based on the conditions regarding the usage status of the POS terminal 20 (for example, when the log-off state is changed to the login state, the login state is changed to the log-off state, or the log-off state continues for a predetermined time). You may decide on a recommended cash register. That is, as described above, if there is a POS terminal 20 already used by a clerk or the like, the recommended cash register is determined from other than the POS terminal 20 being used, but the clerk is basically logged in. Since it is in the state of being used and the log-off state is basically the state of not being used by the clerk, it depends on whether or not the clerk is logged in (that is, whether or not the clerk is using it). ), The recommended cash register may change (a recommended cash register different from the previous recommended cash register may be decided). In addition to the above, if the log-off state continues for a predetermined time (that is, when the predetermined time has elapsed (not used)), the operation mode may be switched as described above (see FIG. 9). May change. Therefore, in the above cases, the recommended cash register is determined again.

As another example, the recommended cash register may change based on the conditions regarding change (for example, when the condition changes from near-end or near-full to near-end or near-full, or when the near-end or near-full condition is resolved). Therefore, the recommended cash register may be decided again. Further, as another example, since the recommended cash register may change based on the condition regarding the error (for example, when an error occurs), the recommended cash register may be determined again.

Also, because the recommended cash register may change based on the conditions related to the product (sales) (for example, when the promotional item is sold out) (because the status of the situation "promotional item" will be ignored), again. You may decide on a recommended cash register. The same is true for hot snacks.

Also, although it is related to the above (transition of login state / log-off state, etc.), if the operation mode is changed (when the operation mode is switched according to the operation of the clerk), the recommended cash register may change. Therefore, the recommended cash register may be decided again.

Further, the recommended cash register may be determined in place of or in addition to some of the above-mentioned timings, in response to a request from the clerk (operation of the clerk).

(Timing to display recommended cash register)
The recommended cash register may be displayed at all times. For example, the recommended cash register may be displayed on the clerk side display unit of all POS terminals 20 at all times, or the recommended cash register may be displayed on the smartphone owned by the clerk. When displaying the recommended cash register on the POS terminal 20, information for specifying the recommended cash register (cash register number, etc.) may be displayed, or information indicating whether or not the cash register is the recommended cash register may be displayed. (For example, if you are the recommended cash register, you may display "Recommended" or "Recommended: 〇", and if you are not the recommended cash register, you may display "Not recommended" or "Recommended: ×") .. In addition, in the mode of always displaying the recommended cash register, the display may be turned off based on the operation of the clerk (the operation of declaring the non-display). It may also be possible to turn the display on again after turning it off.

Further, instead of displaying the recommended cash register at all times, the recommended cash register may be displayed based on a predetermined condition. For example, when the recommended cash register changes (when a recommended cash register different from the previous recommended cash register is determined), the recommended cash register may be displayed on the clerk side display of all POS terminals 20, or the clerk possesses it. You may display the recommended cash register on your smartphone. In addition, the recommended cash register may be displayed based on the operation of the clerk (operation to determine the recommended cash register, operation to display the recommended cash register, login operation, etc.).

According to the above, for example, when logging in to a certain POS terminal 20, if the logged-in POS terminal 20 is a recommended cash register, the POS terminal 20 can be displayed as "recommended" or "recommended: 〇". In addition to or in addition to the above, a message such as "This cash register is a recommended cash register" may be displayed.

On the other hand, when logging in to a certain POS terminal 20, if the logged-in POS terminal 20 is not the recommended cash register, the POS terminal 20 can be displayed as "not recommended" or "recommended: x". In addition to or in addition to the above, a message such as "This cash register is a non-recommended cash register" may be displayed. For example, "This cash register is a non-recommended cash register. 〇〇 cash register is a recommended cash register." A message prompting you to move to the recommended cash register (use of the recommended cash register) may be displayed. In addition to or in addition to the above, the reason for the non-recommended cash register may be displayed. For example, a message urging the reason for the non-recommended cash register and the move to the recommended cash register may be displayed, such as "This cash register is a non-recommended cash register with a small amount of change. For example, a message such as "Please move to the XX cash register to make oden positive" may be displayed that does not directly (actively) indicate the reason for the deprecated cash register. In addition, the message "Please move to the XX cash register to make oden positive" also indicates instructions other than moving the cash register (specifically, sales promotion of oden).

You may also ask the clerk to operate when you log in. For example, when the logged-in POS terminal 20 is not the recommended cash register, a confirmation screen (for example, a small screen displaying a message indicating that the cash register is not recommended and a "use" button and a "not use" button) is displayed on the clerk side display unit 210. When it is selected to be used (when the "use" button is pressed), the operation at the POS terminal 20 (non-recommended cash register) may be permitted. That is, even when logging in to the POS terminal 20 which is not the recommended cash register, the intention of the clerk may be confirmed and the subsequent use may be continued. If the "Use" button is pressed, the small screen is deleted while maintaining the login state, and if the "Do not use" button is pressed, the log-off state is entered (the small screen is also deleted). Alternatively, when the logged-in POS terminal 20 is not the recommended cash register, a small screen displaying another confirmation screen (for example, a message prompting that the POS terminal 20 is not the recommended cash register or moving to the recommended cash register and an "OK" button" is displayed. ) May be displayed on the display unit 210 on the clerk side, and the operation at the POS terminal 20 (non-recommended cash register) may be prohibited (in other words, the use of the recommended cash register may be forced). If the "OK" button is pressed, the log-off state is set (the small screen is also deleted). Since only the operation of the "OK" button is accepted, the operation on the POS terminal 20 (non-recommended cash register) is prohibited, and as a result, the use of the recommended cash register is forced.

In addition, as described above, the recommended cash register changes depending on various factors such as time zone, error status, and change status. Therefore, when the POS terminal 20 logged in as a recommended cash register and working is not the optimum POS terminal 20 (the score etc. was the maximum before use, but it is not the maximum during use. The logged-in POS terminal Since 20 is not a recommended cash register in the first place, the expression that the cash register is no longer the recommended cash register during login is not appropriate, and if it is expressed, the case where the POS terminal 20 is not the recommended cash register again once logged off. ). If the POS terminal 20 is no longer the optimum one during use, another POS terminal 20 (recommended cash register) may be displayed (introduced) to the clerk in use. For example, the scores and the like of all POS terminals 20 including the POS terminal 20 in use are calculated, and other POS terminals 20 having a higher score and the like than the POS terminal 20 in use and are vacant POS terminals 20 ( The presence or absence of the movable POS terminal 20) may be monitored (regardless of the monitoring entity), and if so, the one with the highest score may be displayed on the clerk side display unit 210 as a recommended cash register. .. It may be displayed even during product registration. In addition, the reason for recommendation may be displayed together with the recommended cash register.

Further, if the POS terminal 20 is no longer the optimum one during use, the clerk may be requested to operate the terminal 20 as in the case of login. Further, the subsequent operation may be prohibited. It is also possible to move to another POS terminal 20 (recommended cash register) during the registration process (between the registration of one item and the pressing of the subtotal button), and when moving, register to the other POS terminal 20 (recommended cash register). It is also possible to send information on finished products. For example, the POS terminal 20 (in use) has a confirmation screen (for example, there is another terminal that has a higher score than the own terminal and is vacant) when the own terminal is not the optimum one. Message (message notifying that the cash register is no longer the optimal cash register, message notifying the reason why the cash register is no longer the optimal cash register, message recommending to move to the optimal cash register, whether or not to move to the optimal cash register (Confirmation message, etc.), "Move" button, "Do not move" button, etc. are displayed on the clerk side display unit 210, and when the "Move" button is pressed, the registration process If it is inside, the registered product information may be sent to the cash register at the destination to log off (the small screen is also deleted) (see FIG. 17). That is, the product processing can be continued at the recommended cash register. The same applies during the settlement process (settlement type, cash deposit information, etc. can be sent to the recommended cash register and product processing can be continued at the recommended cash register).

FIG. 17 is a display example on the clerk side display unit 210. For example, when a clerk is using the POS terminal 20-1 (= No. 1 cash register) in the normal mode, the POS terminal 20-1 is not the optimum one (for example, the POS in use). When the score of the POS terminal 20-3 (= No. 3 cash register) that is vacant is higher than that of the terminal 20-1), the POS terminal 20-1 is the clerk side display unit 210 (registered). On the screen), a small screen (small window) SG04 as shown in FIG. 17 may be displayed. On the small screen SG04, a message notifying the reason why the cash register (No. 1 cash register) is no longer the optimum cash register (the remaining amount of 500-yen coins is low) and a message recommending moving to the optimum cash register (No. 3 cash register). Is displayed. The button BU1 of the small screen SG04 corresponds to the above-mentioned "not move" button, and the button BU2 corresponds to the above-mentioned "move" button. The POS terminal 20-1 (No. 1 cash register) shifts from the normal mode to the full self mode when the button BU2 (“move” button) is pressed. Further, the POS terminal 20-3 (No. 3 cash register), which is the destination, receives information that the "move" button is pressed based on the fact that the button BU2 ("move" button) is pressed. (Acquire) and shift from full self mode to normal mode. That is, paying attention to the POS terminal 20-1 (No. 1 cash register), the operation mode shifts at the timing when the "move" button is pressed instead of the "predetermined time elapsed" shown in FIG. 9 (normal mode → Full self mode). Alternatively, the "move" button corresponds to the "mode switching operation" shown in FIG. 9, and the operation mode shifts (normal mode → full self mode) at the timing when the "move" button is pressed. Further, when paying attention to the POS terminal 20-3 (No. 3 cash register), the information that the "move" button is pressed corresponds to the "mode switching command" shown in FIG. 9, and "move". The operation mode shifts (full self mode → normal mode) based on the button being pressed. The example shown in FIG. 17 is before the product is registered, but when the product is already registered, the information of the registered product is transmitted to the POS terminal 20-3 (No. 3 cash register). Will be done. The mode transition between the normal mode and the full self mode has been described, but the same applies to other combinations.

FIG. 18 is a schematic sketch of the store. The three POS terminals 20 shown in FIG. 18 correspond to the three POS terminals 20 shown in FIG. 16 (A). FIG. 19A is an example of a recommended condition table. The rows a to f in FIG. 19 (A) correspond to the rows a to f shown in FIG. 16 (B). 19 (B) to 19 (G) are examples of score determination criteria.

Hereinafter, the recommended condition table will be described with reference to FIGS. 18 and 19. The recommended condition table shown in FIG. 19 (A) is referred to by the entity that determines the recommended cash register (hereinafter, as an example, the store controller 10 determines the recommended cash register) when determining the recommended cash register. Information. The recommended condition table is stored in a place where the entity (store controller 10) that determines the recommended cash register can refer to it. For example, it may be stored in the own terminal (store controller 10), or may be stored in a location referenced via the network.

In FIG. 19A, row a shows the score for "cash (change)" of each POS terminal 20. Specifically, for example, the POS terminal 20-1 has a 500 yen coin outside the standard value, the POS terminal 20-2 has all denominations within the standard value, and the POS terminal 20-3 has a 1000 yen bill. If it is outside the standard value, the score for "cash (change)" is "10" for the POS terminal 20-1 and the POS terminal for the score for "cash (change)" based on the judgment criteria for the score for "cash (change)" in FIG. 19 (B). 20-2 is "20" and POS terminal 20-3 is "10". That is, the POS terminal 20-1 is set to "10" because one denomination (500 yen coin) is out of the standard number. The POS terminal 20-2 is set to "20" because all denominations are within the standard number. The POS terminal 20-3 is set to "10" because one denomination (thousand yen bill) is out of the standard number.

The score regarding "cash (change)" of each POS terminal 20 is appropriately updated according to the cash status of each POS terminal 20. The entity that updates the score related to "cash (change)" is not particularly limited, but for example, the entity that determines the recommended cash register (store controller 10) acquires information on the cash status from each POS terminal 20 and updates it. May be good. The score related to "cash (change)" of each POS terminal 20 may be updated when the recommended cash register is determined, instead of updating as appropriate according to the cash status of each POS terminal 20. The same applies to other scores (for example, a score related to "error" and a score related to "operation mode").

In addition, the criteria for determining the score regarding "cash (change)" in FIG. 19B may be updated as needed. The same applies to the criteria for determining each score shown in FIGS. 19 (C) to 19 (G).

In FIG. 19A, line b shows the score for each POS terminal 20 "error". Specifically, for example, the POS terminal 20-1 has two severe errors (for example, poor communication), the POS terminal 20-2 has no error, and the POS terminal 20-3 has a minor error (fishing tag). When there is only one jam), the score for "error" is "-4" for POS terminal 20-1 and "-4" for POS terminal 20- based on the criteria for the score for "error" in FIG. 19 (C). 2 is "0" and POS terminal 20-3 is "-1". That is, the POS terminal 20-1 becomes "-4" because the severe error is twice. The POS terminal 20-2 is "0" because there is no error. The POS terminal 20-3 becomes "-1" because there is only one minor error.

The score related to the "error" of each POS terminal 20 is appropriately updated according to the error occurrence status of each POS terminal 20. The subject for updating the score regarding "error" is not particularly limited, but for example, the store controller 10 may acquire and update information regarding each POS terminal 20 or the occurrence status of an error.

In FIG. 19 (A), the row c shows the score for the "promotional item" of each POS terminal 20. Specifically, for example, the POS terminal 20-1 has no promotional items in the vicinity, the POS terminal 20-2 has a large number of promotional items in the vicinity, and the POS terminal 20-3 has a small number of promotional items in the vicinity. (As shown in FIG. 19, there are no promotional items in the vicinity of the POS terminal 20-1, there are many promotional items in the vicinity of the POS terminal 20-2, and there are a few promotional items in the vicinity of the POS terminal 20-3. (If there is), based on the criteria for determining the score for "promotional products" in FIG. 19 (D), the score for "promotional products" (normal score) is "0" for POS terminal 20-1 and POS terminal 20. -2 is "5" and POS terminal 20-3 is "2". That is, the POS terminal 20-1 is set to "0" because it is not suitable for sales promotion. The POS terminal 20-2 is set to "5" because it is suitable for sales promotion. The suitability of the POS terminal 20-3 is usually "2".

Note that FIG. 19A shows the score for the “promotional product” in the normal time, but the score for the “promotional product” at the time of strengthening the sales promotion is different. Specifically, the POS terminal 20-1 that is not suitable for sales promotion is "-5", the POS terminal 20-2 that is suitable for sales promotion is "10", and the POS terminal 20-3 that is usually suitable for sales promotion is "2".

In FIG. 19 (A), row d shows the score for the "hot snack" of each POS terminal 20. Specifically, for example, the POS terminal 20-1 has a large number of hot snacks in the vicinity, the POS terminal 20-2 has a small number of hot snacks in the vicinity, and the POS terminal 20-3 has a small number of hot snacks in the vicinity. (As shown in FIG. 18, there are many hot snacks in the vicinity of the POS terminal 20-1, there are a few hot snacks in the vicinity of the POS terminal 20-2, and there are hot snacks in the vicinity of the POS terminal 20-3. If not), the score for "hot snack" (score during sales hours) is "5" for POS terminal 20-1 and POS terminal, based on the criteria for the score for "hot snack" in FIG. 19 (E). 20-2 is "2" and POS terminal 20-3 is "0". That is, the POS terminal 20-1 is set to "5" because it is suitable for hot snack sales. The POS terminal 20-2 is set to "2" because its suitability is normal. The POS terminal 20-3 is set to "0" because it is not suitable for hot snack sales.

Note that FIG. 19A shows the scores for the “hot snacks” in the sales time zone, but the scores for the “hot snacks” in the non-sales time zone (when cleaning furniture, etc.) are different. Specifically, all three POS terminals 20 are set to "0".

In FIG. 19A, the row e shows the score for the "layout" of each POS terminal 20. Specifically, for example, when the POS terminal 20-1 is near the doorway, the POS terminal 20-2 is near the break of the counter, and the POS terminal 20-3 is near the backyard (see FIG. 18), FIG. Based on the criteria for the score related to "layout" in 19 (F), the score related to "layout" (score in the normal time zone) is "5" for POS terminal 20-1 and "10" for POS terminal 20-2. , POS terminal 20-3 becomes "5". That is, the POS terminal 20-1 is set to "5" because the distance from the cut is normal. The POS terminal 20-2 is "10" because it is close to the cut. The POS terminal 20-3 is "0" because it is far from the cut.

Note that FIG. 19A shows the score for the “layout” in the normal time zone, but the score for the “layout” in the midnight time zone (security enhancement time zone) is different. Specifically, the POS terminal 20-1 near the doorway is "10", the POS terminal 20-2 with a normal distance from the doorway is "10", and the POS terminal 20-3 far from the doorway is "0". ..

In FIG. 19A, row f shows the score for the "operation mode" of each POS terminal 20. Specifically, for example, the POS terminal 20-1 is in the full self mode, the POS terminal 20-2 is in the semi-self mode (registration-only mode), and the POS terminal 20-3 is in the normal mode (see FIG. 18). , Based on the judgment criteria of the score regarding the "operation mode" in FIG. 19 (G), the score regarding the "operation mode" is "0" for the POS terminal 20-1, "5" for the POS terminal 20-2, and the POS terminal. 20-3 becomes "10".

The score regarding the "operation mode" of each POS terminal 20 is appropriately updated according to the transition of the operation mode of each POS terminal 20. The subject for updating the score regarding the "operation mode" is not particularly limited, but for example, the store controller 10 may acquire and update information regarding each POS terminal 20 or the operation mode.

In FIG. 19A, “16” under the POS terminal 20-1 indicates each score (score related to “cash (change)”, score related to “error”, ..., “operation mode”) in the POS terminal 20-1. It is the total score which is the sum of the scores). “42” under the POS terminal 20-2 is the total score obtained by summing the scores of the POS terminal 20-2. "26" under the POS terminal 20-3 is the total score obtained by summing the scores of the POS terminals 20-3. Therefore, in the example of FIG. 19A, the POS terminal 20-2 having the maximum total score is determined as the recommended cash register.

In the above description, the store controller 10 calculates the total score of each POS terminal 20 (POS terminal 20-1, POS terminal 20-2, POS terminal 20-3) and determines the recommended cash register. As described above, the decision-making body of the recommended cash register is not limited to the store controller 10. In addition, the calculation body of the total score may be different from the decision body of the recommended cash register. Hereinafter, some of the various aspects will be illustrated.

(Aspect 1)
One representative POS terminal 20 (representative POS terminal 20; one of POS terminal 20-1, POS terminal 20-2, and POS terminal 20-3) has all POS terminals 20 (POS) including its own device. Calculate the total score of terminal 20-1, POS terminal 20-2, and POS terminal 20-3). The representative POS terminal 20 determines the recommended cash register.

(Aspect 2)
The representative POS terminal 20 calculates the total score of all the POS terminals 20 including the own device. Another device (for example, the store controller 10) that has acquired the total score of each POS terminal 20 from the representative POS terminal 20 determines the recommended cash register.

(Aspect 3)
Each POS terminal 20 calculates a total score for each. That is, in FIG. 19A, the POS terminal 20-1 calculates its own total score "16", the POS terminal 20-2 calculates its own total score "142", and the POS terminal 20-3. Calculates its own total score "26". The representative POS terminal 20 acquires the total score of each from the other POS terminals 20 (POS terminals 20 that are not the representative POS terminals 20), and determines the recommended cash register.

(Aspect 4)
Each POS terminal 20 calculates a total score for each. Another device (eg, store controller 10) that has obtained the total score from each POS terminal 20 determines the recommended cash register.

(Aspect 5)
Each POS terminal 20 calculates a total score for each. Each POS terminal 20 shares (sends and receives) a total score with each other to determine a recommended cash register.

Further, in the above, an example of displaying on a screen (POS, mobile phone, etc.) as a method of notifying the recommended cash register has been described, but a lamp or a buzzer may be used. If the decision-making body of the recommended cash register and the display body of the recommended cash register are different, information on the recommended cash register is transmitted from the decision-making body of the recommended cash register to the display body of the recommended cash register.

Although the second embodiment has been described above, according to the second embodiment, a cash register having a plurality of operation modes can be preferably used. For example, since the cash register to be used is determined in consideration of the operation mode, efficient customer service can be performed.

For example, if there is a cash register with sufficient change and a cash register with insufficient change, if a cash register with insufficient change is selected and customer service is continued, replenishment may be required. At convenience stores, etc., there are many cases where there is only one clerk during midnight business hours, and it can be difficult to replenish change away from the cash register. According to the technique shown in the second embodiment, an appropriate cash register can be recommended. Therefore, by using the recommended cash register, efficient customer service can be performed. In addition, it is possible to prevent unexpected troubles (for example, troubles with customers due to running out of change). Since the clerk may serve customers according to the recommendation of the cash register, even a new employee or a foreign clerk with little experience can operate and serve customers with the same efficiency as a skilled clerk.
