(Outline of each operation mode)
Next, operation modes of the second POS terminal 20 will be described. The second POS terminal 20 has multiple operating modes. For example, the second POS terminal 20 has normal mode, full-self mode, and semi-self mode. The operation modes described below are the operation modes during normal business (operation modes related to product registration processing and accounting processing). It does not include the maintenance mode for setting work or maintenance work, or the training mode for training newcomers.

6 to 8 are diagrams for explaining the outline of the operation modes of the second POS terminal 20. FIG. FIG. 6 is a diagram for explaining the outline of the normal mode. FIG. 6A is a schematic diagram showing the flow of processing (merchandise registration processing, checkout processing) and the actions of people (staff, customers) in the normal mode, and FIG. 2 is a flow chart showing the basic flow of the operation of . FIG. 7 is a diagram for explaining the outline of the full-self mode. FIG. 7A is a schematic diagram showing the flow of processing (merchandise registration processing, accounting processing) and actions of people (customers) in the full self mode, and FIG. 2 is a flow chart showing the basic flow of the operation of . FIG. 8 is a diagram for explaining the outline of the semi-self mode. FIG. 8(A) is a schematic diagram showing the flow of processing (product registration processing, accounting processing) and the actions of people (customers) in the semi-self mode, and FIGS. 8(B) and 8(C) in the semi-self mode 4 is a flow chart showing a basic flow of operations of the second POS terminal 20. FIG.

In the following description, the mode in which the second POS terminal 20 executes product registration processing is the registration mode, and the settlement processing is different from the classification of the operation modes (normal mode, full-self mode, semi-self mode) described above. is sometimes referred to as accounting mode.

(normal mode)
The normal mode, as shown in FIG. 6A, is an operation mode in which the store clerk executes registration processing and the customer executes settlement processing. That is, as shown in FIG. 6B, in the normal mode, the store clerk side enters the registration mode, and the customer side enters the checkout mode. In other words, the second POS terminal 20 operates in the registration accounting mode from the registration process to the settlement process as a whole.

In the normal mode, the clerk registers the purchased product of the customer on the clerk side (clerk side scanner section 212, clerk side display section 210, key operation section 211). In other words, the second POS terminal 20 executes the registration process of the purchased product by the clerk's operation (operation of the clerk's scanner unit 212, the clerk's display unit 210, the key operation unit 211, etc.) (the upper part of FIG. 6A). ).

When the registration processing by the clerk is completed, the customer confirms the total amount of purchased commodities on the clerk-side display unit 210, inserts money into the change machine 209, or operates the card payment unit 208 to make a payment (FIG. 6). (A) lower row). That is, the second POS terminal 20 executes the settlement process according to the customer's operation (insertion of money into the change machine 209, operation of the card payment unit 208) (lower part of FIG. 6A).

That is, in the normal mode, as shown in FIG. 6B, the store clerk first scans the product, for example, by the store clerk scanner unit 212 (step S10: YES), and registers the product (step S11). After pressing the subtotal key (for example, the subtotal key displayed on the store clerk side display unit 210 or the subtotal key arranged on the key operation unit 211, etc.) (step S30: YES), for example, the change machine 209 is performed (step S50), and the process is completed. The subtotal key in step S30 is an operation key for completing the registration process, and may also be referred to as a subtotal button, registration completion key, registration completion button, checkout key, checkout button, or the like.

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

In addition, the salesclerk may wait until the customer completes the payment (until the customer obtains change or a receipt), or may register the next customer's purchased product. In other words, the second POS terminal 20 can register the purchased product of the next customer during the checkout process (lower part of FIG. 6A). Also, the clerk may be absent during the checkout by the customer (lower part of FIG. 6(A)). In other words, the reception of the customer may be finished during the payment of the customer.

In addition, when there is change, the second POS terminal 20 controls the dispensing of change and bills by the change machine 209 in order to prevent forgetting to take the change, and detects when the customer has removed the change or bills. , etc., and then control the receipt issuance by the printing unit 213 . The same applies to other operation modes. As described above, in the normal mode, there may or may not be a store clerk in front of the customer who receives the change. (The payout of the bill and the issue of the receipt may be performed at the same time, or the receipt may be issued first). Further, the timing of paying out change/tills and issuing receipts may be controlled according to the current operation mode and the presence/absence of a clerk (for example, the presence/absence of a clerk is recognized by a sensor).

(Full self mode)
As shown in FIG. 7A, the full self mode is an operation mode in which the customer performs registration processing and the customer performs settlement processing. That is, as shown in FIG. 7B, in the case of the full self mode, the customer side becomes both the registration mode and the checkout mode. In other words, the second POS terminal 20 operates in the registration accounting mode from the registration process to the settlement process as a whole.

In the case of the full self mode, the customer registers the purchased product on the customer side (customer side scanner section 206, customer side display section 205). In other words, the second POS terminal 20 executes the registration process of the purchased product according to the customer's operation (scanning by the customer-side scanner unit 206, touching the customer-side display unit 205) (upper part of FIG. 7A).

When the registration process is completed, the customer confirms the total amount of purchased products on the customer-side display unit 205, inserts money into the change machine 209, or operates the card settlement unit 208 to settle the account (Fig. 7 (A) ) below). That is, the second POS terminal 20 executes the settlement process according to the customer's operation (insertion of money into the change machine 209, operation of the card payment unit 208) (lower part of FIG. 7A).

That is, in the full-self mode, as shown in FIG. 7B, the product is scanned by, for example, the customer-side scanner unit 206 on the customer side (step S20: YES), and the product is registered (step S21). After the registration completion key (for example, the registration completion key displayed on the customer-side display unit 205) is pressed (step S40: YES), the customer's account is settled by, for example, the change machine 209 (step S50), and processing is performed. is completed. The registration completion key related to step S40 is an operation key for completing the registration process, and may also be called a registration completion button, subtotal key, subtotal button, checkout key, checkout button, or the like.

In the full-self mode, as described above, the customer side executes both the registration process and the settlement process, but this does not mean that the store clerk cannot do anything. That is, even when the second POS terminal 20 is operating in the full self mode, for example, the salesclerk side scanner unit 212 can scan the salesclerk code. A state (operation mode) in which registration processing is being performed on both the store clerk side and the customer side may be referred to as a double scan mode.

(Semi-self mode)
The semi-self mode is divided into a registration-only mode in which the store clerk executes the registration process and a checkout-only mode in which the customer executes the settlement process. The example of FIG. 8 is an example in which the second POS terminal 20-1 operates in the registration-only mode and the second POS terminal 20-2 operates in the accounting-only mode.

In the case of the semi-self mode, the clerk registers the product purchased by the customer on the second POS terminal 20-1 in the registration-only mode on the clerk side (clerk side scanner section 212, clerk side display section 210, key operation section 211). In other words, the second POS terminal 20-1 executes registration processing of purchased products according to the operation of the store clerk (operation of the store clerk-side scanner unit 212, store clerk-side display unit 210, key operation unit 211, etc.) (FIG. 8A). upper row).

When the registration process by the clerk is completed, the customer moves to the second POS terminal 20-2 in the checkout-only mode, checks the total amount of purchased commodities on the clerk-side display unit 210, inserts money into the change machine 209, or , operate the card settlement unit 208 to settle the account (lower part of FIG. 8(A)). In other words, the second POS terminal 20-2 executes settlement processing according to the customer's operation (insertion of money into the change dispenser 209, operation of the card settlement unit 208) (lower part of FIG. 8A).

When the registration process is completed at the second POS terminal 20 in registration-only mode (the second POS terminal 20-1 in the example of FIG. 8), the customer transfers from the second POS terminal 20 in registration-only mode to the second POS terminal 20 in accounting-only mode ( In the example of FIG. 8, it moves to the second POS terminal 20-2), and the second POS terminal 20 at the destination is supplied with information (registration information, etc.) necessary for settlement processing.

Required for settlement processing from the second POS terminal 20 in registration-only mode (second POS terminal 20-1 in the example of FIG. 8) to the second POS terminal 20 in accounting-only mode (second POS terminal 20-2 in the example of FIG. 8) As a method of supplying information, information necessary for settlement processing is transmitted from the second POS terminal 20 in the registration-only mode to the second POS terminal 20 in the accounting-only mode (may be transmitted via the store controller 30; the same shall apply hereinafter). and a method of issuing a medium (a medium on which a barcode or the like for obtaining information necessary for settlement processing is printed) at the second POS terminal 20 in registration-only mode.

In the example of FIG. 8, there is only one second POS terminal 20 in accounting-only mode (the second POS terminal 20-2), but there are two or more second POS terminals 20 in accounting-only mode. In this case, the second POS terminal 20 in the registration-only mode (the second POS terminal 20-1 in the example of FIG. 8) may specify the POS terminal (the second POS terminal 20 in the accounting-only mode) to execute the settlement process. . Note that when a medium (a medium on which a barcode or the like for obtaining information necessary for settlement processing is printed) is issued at the second POS terminal 20 in the registration-only mode, the account-only mode that reads the medium is Settlement processing is executed at the second POS terminal 20 .

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

In the example of FIG. 8B, when the product registration is completed, the subtotal key is pressed first, and then (after the subtotal key is pressed), the second POS terminal 20 is specified. A processing procedure may be such that the second POS terminal 20 is specified directly (without pressing the subtotal key) at the time of termination. In the latter case, there is no need to display the subtotal key on the screen.

Subsequently, as shown in FIG. 8C, the second POS terminal 20 (second POS terminal 20-2) specified by the second POS terminal 20 (second POS terminal 20-1) in the registration-only mode receives the registration information. After receiving the data (step S49: YES), the customer pays the bill by, for example, the change dispenser 209 (step S50), and the process is completed.

After transmitting the registration information (or after issuing the medium), the store clerk can register the next customer's purchased product (lower part of FIG. 8A). Also, the clerk may be absent after transmitting the registration information (lower part of FIG. 8(A)).

In the example of FIG. 8, the second POS terminal 20-2 in checkout-only mode executes the checkout process using the product registration information registered in the second POS terminal 20-1 in registration-only mode. In other words, the registration information used by the second POS terminal 20-2 in the checkout-only mode for settlement processing is the registration information of the product registered when the second POS terminal 20-1 is operating in the registration-only mode. However, if it is possible to transmit the registration information to the second POS terminal 20-2 in accounting-only mode (or if it is possible to issue an accounting coupon (registered trademark; hereinafter the same)), the second POS terminal 20-2 in accounting-only mode The registration information used by -2 for settlement processing does not necessarily have to be the registration information of the product registered when the second POS terminal 20-1 is operating in the registration-only mode.

As an example, the registration information used for settlement processing by the second POS terminal 20-2 in the checkout-only mode may be the registration information of the product registered when the second POS terminal 20-1 is operating in the normal mode. In other words, the second POS terminal 20-2 in the checkout-only mode may execute the checkout process using the product registration information registered when the second POS terminal 20-1 is operating in the normal mode.

When the clerk of the second POS terminal 20-1 completes the registration process (when attempting to transmit registration information or when issuing an accounting ticket), the customer performs an adjustment operation (change dispenser 209). and operation of the card payment unit 208) have already started, the transmission of registration information or the issuance of accounting coupons may be prohibited, or the operation of settlement may be canceled. .

As another example, if the first POS terminal 10 has a function of transmitting registration information (or issuing an accounting coupon) to the second POS terminal 20-2 in accounting-only mode (for example, the function from the beginning, or when the function is added as a function addition), the registration information used by the second POS terminal 20-2 in the accounting-only mode for settlement processing is the first POS terminal 10 may be registered information of a product registered by That is, the second POS terminal 20-2 in the checkout-only mode may use the product registration information registered by the first POS terminal 10 to perform the checkout process.

In the example of FIG. 8, the second POS terminal 20-2 receives registration information (or reads an accounting ticket) and executes settlement processing while operating in the accounting-only mode. However, if the settlement process can be executed after receiving the registration information (or after reading the accounting coupon), the second POS terminal 20-2 receives the registration information (or reads the accounting coupon). The operational mode need not necessarily be an accounting-only mode.

As an example, the second POS terminal 20-2 receives registration information from other terminals (for example, the second POS terminal 20-1 and the first POS terminal 10) when operating in the full self mode, and receives registration information from the other terminals. The settlement process may be executed using the registered information. Further, the second POS terminal 20-2 reads accounting tickets issued by other terminals (for example, the second POS terminal 20-1 and the first POS terminal 10) while operating in the full self mode, and The settlement process may be executed using the registration information obtained from the accounting ticket read from the .

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

Specifically, the flowchart of FIG. 18 shows an example of the operation of the second POS terminal 20-1 in the semi-self mode (accounting mode) depending on whether or not the registration information is received. Note that the flowchart of FIG. 18 is started as appropriate. It is also assumed that the operation mode of the second POS terminal 20-1 is the semi-self mode (accounting mode) at the start of the flowchart of FIG.

Step S302: The second POS terminal 20-1 determines whether it has received the registration information. If received (step S302: YES), the process proceeds to step S303. If not received (step S302: NO), the process proceeds to step S304.
Step S303: The second POS terminal 20-1 stores the received registration information in the RAM 203 or the like.

Step S304: The second POS terminal 20-1 determines whether or not processing is in progress (accounting process in progress). If processing is not being performed (step S304: NO), the process proceeds to step S305. If processing is in progress (step S304: YES), the process returns to step S302. That is, if the processing is in progress, the processing is continuously executed until the processing is completed, and the process proceeds to step S305 after the processing is completed.

Step S305: The second POS terminal 20-1 determines whether or not the registration information is stored. If the registration information is stored (step S305: YES), the process proceeds to step S308. If the registration information is not stored (step S305: NO), the process proceeds to step S310.
Step S308: The second POS terminal 20-1 displays the settlement screen in the semi-self mode (accounting mode) as in step S108 of FIG.

Step S310: The second POS terminal 20-1 displays a standby screen in semi-self mode (accounting mode) as shown in FIG. 15(A).

Step S312: The second POS terminal 20-1 determines whether it has received the registration information. If received (step S312: YES), the process proceeds to step S313. If not received (step S312: NO), the process proceeds to step S315.
Step S313: The second POS terminal 20-1 stores the received registration information in the RAM 203 or the like.

Step S315: The second POS terminal 20-1 determines whether or not registration information is stored. If the registration information is stored (step S315: YES), the process proceeds to step S308. If the registration information is not stored (step S315: NO), the process proceeds to step S316.
Step S316: The second POS terminal 20-1 determines whether or not a predetermined period of time has elapsed, that is, whether or not the elapsed time (for example, the elapsed time since the standby screen was displayed) has exceeded a predetermined period of time. If it has not passed (step S316: NO), the process returns to step S312. If it has passed (step S316: YES), the process proceeds to step S326.

Step S326: The second POS terminal 20-1 changes the operation mode from the semi-self mode (accounting mode) to the full self mode. In the process of step S326, the second POS terminal 20-1 updates the terminal status management information of its own terminal from information indicating that it is in semi-self mode (accounting mode) to information indicating that it is in full self mode. It may include a process to do.
Step S327: The second POS terminal 20-1 transmits mode change information.
Step S328: The second POS terminal 20-1 displays a full self-mode registration start screen.

As described above, according to FIGS. 17 and 18, for example, when the number of people waiting to register at the second POS terminal 20 in semi-self mode increases, registration information is sent to the second POS terminal 20 in full self mode, which is relatively free. It can be taken over (see FIG. 17). As a result, customer handling can be performed smoothly. Also, when the second POS terminal 20 in semi-self mode is idle (when the clerk is not operating it), it can be automatically switched to full self mode (see FIG. 18). This makes it possible to effectively utilize available terminals. For customers who seem unfamiliar with product registration (elderly people, etc.), the store clerk registers products using the first POS terminal 10 or the second POS terminal 20 in semi-self mode (that is, manned service). If the customer is unfamiliar with the payment, it is possible to skip the registration information of the other terminal and have the customer perform the payment himself/herself at the other terminal (that is, unattended handling). In other words, since it is possible to freely switch the operation mode as appropriate, for example, it is possible to operate according to the situation. It is also possible to charge prepaid cards. For example, the process up to the charging of the prepaid card may be manned, and the rest (payment) may be unmanned by transmitting the charge amount to another terminal.

(Conditions for sending registration information)
In the example shown in FIG. 16, no particular conditions are set for the transmission of the registration information to the second POS terminal 20-1 in the full self mode, but conditions may be set for the transmission of the registration information to the second POS terminal 20 in the full self mode. can be Specifically, whether or not to transmit the registration information to the second POS terminal 20 in full-self mode is determined according to the processing status of the second POS terminal 20 as shown in FIGS. condition) may be controlled.

The flowchart of FIG. 19A shows the operation of the second POS terminal 20-1 in full self mode. It is assumed that at the start of the flowchart of FIG. 19A, the second POS terminal 20-1 displays a registration screen (initial state registration screen) in which one product item is not yet registered.

Step S400: The second POS terminal 20-1 starts registering the purchased product in response to the customer's operation (for example, the product registration operation by the customer-side scanner unit 206).
Step S401: Control information (transmission restriction start information) for starting restriction of transmission of registration information from the other terminal to its own terminal (second POS terminal 20-1) is transmitted to the other terminal. It may be transmitted via store controller 30 .

Step S402: Receive operation of checkout button BT32. In other words, an instruction to complete the registration of purchased products is accepted.
Step S403: Display the settlement screen (payment method selection screen).
Step S404: Receive selection of cash as a payment method.
Step S405: Display the settlement screen (deposit screen where the deposit amount is 0 yen).
Step S406: Count the deposit amount (money inserted by the customer).
Step S407: Display the settlement screen (deposit screen with updated deposit amount). In other words, the count result is displayed.

Step S408: The operation of the end (receipt) button BT40 is accepted. In other words, it accepts the operation of fixing the deposit amount.
Step S409: Control information (transmission restriction end information) for ending (releasing) the restriction on transmission of registration information from the other terminal to the own terminal is transmitted to the other terminal. It may be transmitted via store controller 30 .

Step S410: The settlement screen (change screen) is displayed, and if there is change, the change is released.
Step S411: Detecting that the change has been removed.
Step S412: A settlement screen (receipt screen) is displayed, and a receipt is printed and issued.
Step S413: Detecting that the receipt has been removed.
Step S414: The registration screen in the initial state is displayed for the next customer.

The flowchart of FIG. 20(A) shows the operation of the first POS terminal 10 . It is assumed that the first POS terminal 10 appropriately starts the flowchart of FIG. 20(A). FIGS. 20B and 20C are examples of terminal state management information.

Step S501: Determine whether or not transmission restriction start information transmitted from another terminal has been received. If the transmission restriction start information has been received, the process proceeds to step S501. If the transmission restriction start information has not been received, the process proceeds to step S510.
Step S501: Restrict (prohibit) the transmission of registration information to the source terminal of the transmission restriction start information until the transmission restriction end information is received. For example, the first POS terminal 10 may use the terminal state management information to control whether or not to transmit registration information (restriction, release of restriction).

The terminal state management information is information (flag, classification information, status information, etc.) for managing the state of each terminal (own terminal, other terminals). FIG. 20B shows terminal state management information stored in the first POS terminal 10 at a certain time. The terminal state management information in FIG. 20B includes "1 (operating)" as information regarding the state of the own terminal (first POS terminal 10) and "F" as information regarding the state of the other terminal (second POS terminal 20-1). (full self mode)", "1 (sendable)" as information about whether or not to transmit the registration information to the other terminal (second POS terminal 20-1), and " K (dormant)", and "0 (transmittable)" as information on whether or not the registration information can be transmitted to the other terminal (second POS terminal 20-2). FIG. 20C shows terminal state management information stored by the first POS terminal 10 at other times. The terminal state management information of FIG. 20(C) is different from the terminal of FIG. Different from state management information.

For example, when the first POS terminal 10 receives the transmission restriction start information transmitted from the second POS terminal 20-1 in step S500, in step S501, the first POS terminal 10 determines whether or not the registration information can be transmitted to the second POS terminal 20-1. The information is updated from "1 (transmittable)" to "0 (transmittable)". That is, the terminal state management information stored as shown in FIG. 20B, for example, in the process of step S501 is updated as shown in FIG. 20C.

Step S510: Determine whether or not transmission restriction end information transmitted from another terminal has been received. If the transmission restriction end information has been received, the process proceeds to step S511. If the transmission restriction end information has not been received, the process proceeds to step S511.
Step S511: Release the restriction on transmission of registration information to the terminal that transmitted the transmission restriction end information.

For example, when the first POS terminal 10 receives the transmission restriction end information transmitted from the second POS terminal 20-1 in step S510, in step S511, the first POS terminal 10 confirms whether or not the registration information can be transmitted to the second POS terminal 20-1. Update the information from "0 (cannot be sent)" to "1 (can be sent)". In other words, the terminal status management information stored as shown in FIG. 20(C), for example, in the process of step S511 is updated as shown in FIG. 20(B).

The terminal status management information shown in FIG. 20(D) is the terminal status management information stored by the second POS terminal 20-1 when the registration screen shown in FIG. 14 is displayed. The terminal status management information in FIG. 20(D) includes "ST (semi-self mode (registration-only mode))" as information about the status of the own terminal (second POS terminal 20-1), and the status of the other terminal (first POS terminal 10). "1 (in operation)" as information about the status of the terminal (first POS terminal 10), "0 (transmittable)" as information about whether or not the registration information can be transmitted to the other terminal (first POS terminal 10), and information about the status of the other terminal (second POS terminal 20-2) 'K (dormant)' as a terminal, and '0 (transmittable)' as information regarding whether or not registration information can be transmitted to another terminal (second POS terminal 20-2).

As described above, according to FIGS. 19A and 20, when the second POS terminal 20-1 in full self mode starts registering purchased products (step S400 in FIG. 19A), the transmission restriction start information is transmitted (step S401 in FIG. 19A). When the first POS terminal 10 receives the transmission restriction start information transmitted from the second POS terminal 20-1 (step S500 in FIG. 20: YES), it restricts transmission of the registration information to the second POS terminal 20-1 (FIG. 20 step S501). Further, when the second POS terminal 20-1 in the full-self mode receives an operation to confirm the deposit amount (step S408 in FIG. 19A), it transmits transmission restriction end information (step S409 in FIG. 19A). ). When the first POS terminal 10 receives the transmission restriction end information transmitted from the second POS terminal 20-1 (step S510 in FIG. 20: YES), it cancels the restriction on transmission of registration information to the second POS terminal 20-1 ( 20 step S511). In other words, according to FIGS. 19A and 20, the transmission of registration information to the second POS terminal 20 in full self mode is not limited to the period before registration of one purchased product and after determination of the deposit amount ( (Transmission of registered information is permitted), but the period from the registration of one purchased product to the determination of the deposit amount is limited (transmission of registered information is not permitted).

19A and 20, the control of whether or not to transmit registration information to the second POS terminal 20 in full self mode has been described, but as shown in FIG. Whether or not to transmit the registration information to the second POS terminal 20 may be similarly controlled.

The flowchart of FIG. 19(B) shows the operation of the second POS terminal 20-2 in the semi-self mode (accounting mode) (that is, in the description of FIG. 19(B), the second POS terminal 20-2 mode (accounting-only mode). It is assumed that the second POS terminal 20-2 displays the standby screen (FIG. 15A) at the start of the flowchart of FIG. 19B.

Step S420: Receive and store the registration information.
Step S421: Control information (transmission restriction start information) for starting restriction of transmission of registration information from the other terminal to its own terminal (second POS terminal 20-2) is transmitted to the other terminal. It may be transmitted via store controller 30 .

Since each process of steps S423 to S433 is the same as each process (each process of steps S403 to S413) within the dashed line P in FIG. 19A, description thereof will be omitted.

Step S434: Display a standby screen or a payment method selection screen. For example, if the registration information of the next customer has not been received from the time the change is released until the receipt is detected, the standby screen is displayed, and if the receipt has been received, the payment is made. Display the method selection screen.

As described above, according to FIGS. 19B and 20, when the second POS terminal 20-2 in the semi-self mode (accounting mode) receives and stores the registration information (step S420 in FIG. 19B), the transmission is restricted. Start information is transmitted (step S421 in FIG. 19B). When the first POS terminal 10 receives the transmission restriction start information transmitted from the second POS terminal 20-2 (step S500 in FIG. 20: YES), it restricts transmission of the registration information to the second POS terminal 20-2 (FIG. 20 step S501). Further, when the second POS terminal 20-2 in the semi-self mode (accounting exclusive mode) receives an operation to confirm the deposit amount (step S428 in FIG. 19B, step S408 in FIG. 19A), the transmission restriction ends. Information is transmitted (step S429 in FIG. 19B, step S409 in FIG. 19A). When the first POS terminal 10 receives the transmission restriction end information transmitted from the second POS terminal 20-2 (step S510 in FIG. 20: YES), it cancels the restriction on transmission of registration information to the second POS terminal 20-2 ( 20 step S511). In other words, according to FIGS. 19B and 20, transmission of registration information to the second POS terminal 20 in semi-self mode (accounting only mode) is not limited to the period before receiving the registration information and after the deposit amount is determined. (Although transmission of registration information is permitted), the period from receipt of registration information to determination of deposit amount is limited (transmission of registration information is not permitted).

FIG. 21 is a flow chart showing an example of the operation of the second POS terminal 20. As shown in FIG. Specifically, FIG. 21A shows an operation example of reading various information by the customer-side scanner unit 206 in an operation mode (full-self mode) in which only the customer registers products. The second POS terminal 20 operating in the full-self mode appropriately starts the flowchart of FIG. 21(A) during the registration process. Note that operations other than those related to the customer-side scanner unit 206 are omitted in the flowchart of FIG. 21(A).

Step S600: It is determined whether information has been read by the customer-side scanner unit 206 or not. If information is read by the customer-side scanner unit 206 (step S600: YES), the process proceeds to step S601. If the information is not read by the customer-side scanner unit 206 (step S600: NO), the process ends.

Step S601: Determine whether the read information is a product code. That is, it is determined whether or not the bar code attached to the product has been read. If it is a product code (step S601: YES), the process proceeds to step S602. If it is not a product code (step S601: NO), the process proceeds to step S603.
Step S602: The product code is stored, and information obtained based on the product code (for example, product name, unit price, etc.) is displayed on the customer side display section 205 and the store clerk side display section 210. FIG. and finish.

Step S603: Determine whether the read information is member identification information (member number, member code, customer number, customer identification information). That is, it is determined whether or not the bar code or the like attached to the membership card or the like has been read. If it is member identification information (step S603: YES), the process proceeds to step S604. If it is not member identification information (step S603: NO), the process proceeds to step S605.
Step S604: The member identification information is stored, and information obtained based on the member identification information (for example, member name, number of points, etc.) is displayed on the customer side display section 205 and the store clerk side display section 210. FIG. and finish.

Step S605: It is determined whether or not the read information is privilege identification information (identification information of coupons, gift certificates, etc.). That is, it is determined whether or not the bar code or the like attached to the coupon or the like has been read. If it is privilege identification information (step S605: YES), the process proceeds to step S606. If it is not member identification information (step S605: NO), the process proceeds to step S605. Note that gift certificates may be given to customers unconditionally or by lottery during a campaign period, in units of one or a set of several coupons, or they may be given to a specific target person as a complimentary ticket. There may be one, or a sold one (11 coupons, each of which can be exchanged for one product and sold for the price of ten products, etc.).
Step S606: The privilege identification information is stored, and information (for example, discount information, etc.) obtained based on the privilege identification information is displayed on the customer side display section 205 and the store clerk side display section 210. FIG. and finish.
Step S607: An error message is displayed on the customer side display section 205 and the store clerk side display section 210. FIG. In other words, if the read information is neither the product code, the member identification information, nor the privilege identification information, an error message is displayed on the customer side display section 205 and the store clerk side display section 210 . For example, a message such as "not to be read" is displayed on the customer side display section 205 and the store clerk side display section 210. FIG. In addition, a message such as "Not applicable for reading" is displayed on the customer side display section 205, and an error message is displayed on the customer side because the information not covered by the scan is displayed on the clerk side display section 210. ” or the like may be displayed. and finish.

FIG. 21B shows an operation example of reading various information by the customer-side scanner unit 206 in an operation mode (normal mode, semi-self mode (registration-only mode)) in which only the store clerk registers products. The second POS terminal 20 operating in the normal mode or the semi-self mode (registration-only mode) appropriately starts the flowchart of FIG. 21(B) during the registration process. Note that the operation other than the operation related to the customer-side scanner unit 206 is omitted in the flowchart of FIG. 21(B).

Step S610: It is determined whether information has been read by the customer-side scanner unit 206 or not. If information is read by the customer-side scanner unit 206 (step S610: YES), the process proceeds to step S611. If the information has not been read by the customer-side scanner unit 206 (step S610: NO), the process ends.

Step S611: It is determined whether or not the read information is a product code. That is, it is determined whether or not the bar code attached to the product has been read. If it is a product code (step S611: YES), the process proceeds to step S612. If it is not a product code (step S611: NO), the process proceeds to step S613.
Step S612: An error message is displayed on the customer side display section 205 and the store clerk side display section 210. FIG. In other words, in the operation mode in which only the store clerk registers the product, unlike the operation mode in which only the customer registers the product, an error message is displayed on the customer side display unit 205 and the store clerk side display unit 210 when the product code is read. indicate. For example, a message such as "Product cannot be registered" is displayed on the customer side display section 205 and the store clerk side display section 210. FIG. A message such as "The product cannot be registered." A message such as "Done" may be displayed.

Since each process of steps S613 to S617 is the same as each process of steps S603 to S607 in FIG. 21A, description thereof is omitted. As shown in FIGS. 21A and 21B, when the second POS terminal 20 is in the full self mode, the customer-side scanner unit 206 scans all of the product code, member identification information, and benefit identification information. is permitted, and when the operation mode is the normal mode or the semi-self mode (registration-only mode)), scanning of the product code is prohibited, while scanning of the member identification information and privilege identification information is permitted.

As described above, according to the operations shown in FIGS. 21A and 21B, the customer-side scanner section 206 can be suitably controlled according to the situation. Specifically, it is possible to appropriately control whether or not the product code can be read by the customer-side scanner unit 206 according to the operation mode. Further, reading of the member identification information and privilege identification information is permitted regardless of the operation mode, so the time required for processing can be shortened.

Reading of the identification information by the customer-side scanner unit 206 or the like will be supplemented below.

The second POS terminal 20 may determine which identification information (merchandise code, member identification information, benefit identification information) is based on the read identification information (read information). For example, the second POS terminal 20 may determine which identification information is based on the number of digits of the read information. In addition, instead of or in addition to the number of digits of the read information, the second POS terminal 20 can determine any value based on the value of a predetermined portion of the read information (for example, the first digit, the second digit, the first and second digits, etc.). You may judge whether it is identification information.

The flowchart of FIG. 21(A) shows an operation example in an operation mode (full self mode) in which a customer registers products exclusively, and the flowchart in FIG. , semi-self mode (registration-only mode)), but in the case of the operation mode (double scan mode) in which the clerk and the customer register the product, the operation mode in which the customer registers the product (full self mode) ) (FIG. 21A).

In other words, in operation modes (full self mode, double scan mode) that allow customers to register products, in addition to member identification information and benefit identification information by the customer-side scanner unit 206, the customer-side scanner unit 206 reads product codes. Permit (FIG. 21(A)). On the other hand, in operation modes (normal mode, semi-self mode (registration-only mode)) that do not allow customers to register products, the customer-side scanner unit 206 is permitted to read the member identification information and privilege identification information. to prohibit the reading of the product code by (Fig. 21(B)).

As shown in FIGS. 21A and 21B, the customer-side scanner unit 206 operates differently depending on the operation mode, but the salesclerk-side scanner unit 212 operates regardless of the operation mode. They may be identical. Specifically, in the case of the store clerk side scanner section 212, the operation is the same as the operation by the customer side scanner section 206 shown in FIG. 21A in any operation mode.

In other words, even in operation modes that allow customers to register products (full-self mode, double scan mode), there are operation modes that do not allow customers to register products (normal mode, semi-self mode (registration-only mode)). However, the store clerk side scanner unit 212 is permitted to read the product code, read the member identification information, and read the benefit identification information (FIG. 21(A)).

Note that in the flowchart of FIG. 21A, when any of the product code, member identification information, or privilege identification information is read by the customer-side scanner unit 206, it is accepted (steps S602, S604, S606), If other information (information that is not the product code, the member identification information, or the privilege identification information) is read by the customer-side scanner unit 206, it is not accepted (step S607). , information on the organization to which the customer belongs (shareholders, group employees, etc.), information on the attributes of the customer (age, nationality, etc.), information on delivery of the product (e.g., ticketing code for issuing tickets, etc.), product (delivery destination/delivery date and time) is read by the customer-side scanner unit 206, it may be accepted. The same applies to the flowchart of FIG. 21(B).

Further, in the case of the store clerk side scanner unit 212, it has been explained that it operates as shown in FIG. However, if the store clerk side scanner unit 212 reads store clerk identification information that identifies a store clerk, transaction identification information that is printed on a medium, etc., they are accepted. good too.

The second POS terminal 20 may notify what is permitted to be read (or what is prohibited from being read) depending on the situation. For example, in the process of FIG. 21(A), the second POS terminal 20 not only reads the product (product code) but also displays the membership card (member identification information) and privilege medium (privilege identification information) on the customer side display unit 205. It may be possible to display that it is possible to read In addition, in the process of FIG. 21B, the second POS terminal 20 may display that the product cannot be read, but the membership card and privilege medium can be read.

Further, the second POS terminal 20 may execute the following processing when a medium (privilege medium) such as a coupon or gift certificate is used.

For example, if the privilege medium used this time cannot be used next time (for example, if the privilege medium used this time is a privilege medium that can only be used once, the privilege medium used this time can be used multiple times). If the privilege media can be used (can be used up to the prescribed number of times of use two or more times), but the current use is the last use (use for the prescribed number of times of use, etc.), etc., collection is required. You can let us know. For example, a collection box for collecting used privilege media is installed at the counter (see FIG. 3), and in the process of step S606 in FIG. A message such as “Please put the used XX ticket in the collection box” may be displayed on the side display unit 205 . Further, instead of or in addition to the display on the customer side display section 205, the clerk side display section 210 may display a message such as "collection of XX tickets required". Also, instead of or in addition to the display on the display section (customer-side display section 205, store clerk-side display section 210), the audio output section 214 may output sound. The same is true for other messages.

As a method for determining whether or not to collect the privilege media, various methods are conceivable in relation to the mode of operation of the privilege media in the store. For example, in a mode in which privilege media that can be used only once are operated, the second POS terminal 20 (CPU 201) always determines that collection is necessary when the read information (identification information) is determined to be privilege identification information. You may In other words, since none of the privilege media used this time can be used next time, it may be determined that recovery is always necessary when the privilege media are read. The same applies to the case of using a plurality of types of privilege media (for example, privilege medium A that can be used only once, privilege medium B that can be used only once) as privilege media that can be used only once. In other words, the type of privilege medium (privilege media A and B) is not relevant when determining whether collection is necessary or not, regardless of which privilege medium is read. good.

A mode of operating privilege media that can be used multiple times (can be used up to a predetermined number of times of use of two or more times) (whether to operate multiple types of privilege media as privilege media that can be used multiple times, It does not matter whether or not privilege media that can be used only once are used), and by managing the number of times of use for each privilege medium (for example, privilege identification information is given for each media, not for each type of privilege media) At the same time, the store controller 30 and the monitoring terminal 40 may determine whether or not collection is necessary by renewably storing the actual number of times of use in association with the respective privilege identification information. That is, the second POS terminal 20 (CPU 201) updates the actual number of times of use corresponding to the read information (privilege identification information) of the privilege medium (for example, transmits the number of times of use update control information to the store controller 30 or the like), and updates the number of times of use. The necessity of recovery may be determined depending on whether or not the number of subsequent usage records reaches the usage limit number.

On the other hand, if the privilege medium used this time can be used again next time If the medium is a privilege medium that can be used multiple times and the current use is not the last use (the maximum number of times of use), the fact that the medium can be used next time may also be notified. For example, in the process of step S606 in FIG. 21(A) (similar to step S616 in FIG. 21(B)), the display unit 205 on the customer side displays the message "You can use your XX ticket any number of times until XX month XX day. You can use it" or "You can use the 〇〇 ticket you are using △ more times by XX month XX day". Further, instead of or in addition to the display on the customer side display section 205, a similar message may be displayed on the clerk side display section 210. FIG.

Note that the usable period may be managed in the same manner as the limit number of times of use. In other words, a message corresponding to the available period may be displayed by storing the available period in association with the privilege identification information in the store controller 30 or the monitoring terminal 40 . If the date and time when the privilege identification information is read is within the usable period and the specific medium can be used again, the above-mentioned "Your 〇〇 ticket can be used as many times as you like until XX month XX day." ' or 'You can use your 〇〇 ticket △ more times by XX month XX day'. In addition, if the read date and time of the privilege identification information is before the start of the usage period, for example, the customer-side display unit 205 will display "Ticket cannot be used at present. A message such as "can be used for XX days" may be displayed. In addition, if the date and time when the privilege identification information is read is after the expiration of the usage period, for example, the customer-side display unit 205 may display "Ticket cannot be used now because the usage period has expired." You may display a message such as "The 〇 ticket cannot be used at this time because the period of use has expired. Please put it in the collection box."

In addition, when a message prompting the collection of special media such as "Please put the XX tickets used in the collection box" is displayed, the process will not proceed unless there is an operation to confirm collection. may For example, when the second POS terminal 20 reads the coupon and determines that collection is necessary during product registration in the full-self mode, the second POS terminal 20, instead of or in addition to notifying that collection is necessary, A "collection OK" button may be displayed on the side display unit 205, and the checkout button BT32 may not be operated unless the "collection OK" button is operated.

In addition to the product code, for example, the privilege medium of the coupon may be readable even at the stage of payment after product registration. In addition, even in a mode in which the coupon can be read at the payment stage, the processing may not proceed unless there is an operation to confirm collection of the coupon. For example, when the second POS terminal 20 reads the coupon in the semi-self mode (accounting mode) and determines that collection is necessary, instead of or in addition to notifying that collection is necessary, the second POS terminal A "collection OK" button may be displayed on the side display unit 205, and the end (receipt) button BT40 may not be operated unless the "collection OK" button is operated.

(About the printing department)
In the above description, the second POS terminal 20 includes one printing unit 213 that can be rotatably changed from the clerk side to the customer side and from the customer side to the clerk side (the direction of the medium issuing port). It is also possible to provide two printing units each having a medium issuing port. In other words, instead of the single printing unit 213 that can rotatably change the direction of the medium issuing port, the second POS terminal 20 has a clerk-side printing unit with a medium issuing port on the store clerk side and a media issuing port on the customer side. A certain customer side printing section may be provided separately.

(About the scanner part)
In the above description, the customer-side scanner unit 206 is of a type held by an operator (clerk, customer) and brought close to an object (product, etc.) to recognize identification information. There may be. For example, it may be a fixed type that recognizes an object by bringing it closer. The same applies to the clerk side scanner unit 212 .

(Switching operation modes, etc.)
When switching the operation mode, the second POS terminal 20 may display that the operation mode is switched on at least one of the customer-side display unit 205 and the store clerk-side display unit 210 . For example, when switching from the full-self mode to the semi-self mode (accounting-only mode) (step S106 in FIG. 16), when switching (or before switching), the customer-side display unit 205 displays "accounting-only mode" for a predetermined time (for example, several seconds). You may display a message such as "Switching to mode". It should be noted that after switching the operation mode, a message indicating that the operation mode has been switched may be displayed.

The second POS terminal 20 selects whether to maintain the full self mode, switch to the normal mode, or switch to the double scan mode when the clerk logs in in the full self mode when the clerk is not logged in. , may be determined according to the operation of the store clerk (for example, button operation).

In other words, the second POS terminal 20 has a button for maintaining the full self mode, a button for switching to the normal mode, a button for switching to the normal mode, and a double scan mode when the clerk logs in in the full self mode when the clerk is not logged in. , and the operation mode after login may be controlled according to which button is operated. In addition, for example, if the customer asks for support to leave the rest of the product registration to the store clerk (if the store clerk is called), the store clerk operates a button to switch to the normal mode after logging in, and the product is registered. After that, if you are asked for support (when the clerk calls) that you will leave part of it to the clerk (the customer will also register, but you want the clerk to cooperate), the clerk will double scan after logging in When the button for switching to the mode is operated and the customer logs in for some reason (for example, confirmation of the processing status), but the customer himself/herself wishes to register or does not need the support of the store clerk (or temporarily and cannot support the customer), the clerk operates a button to maintain the full self mode after login. When the full self mode is maintained after the sales clerk logs in, the sales clerk side display unit 210 may not display the product name of the product registered by the customer from the viewpoint of privacy. However, information that does not significantly affect privacy or the like (accumulated amount during registration, etc.) may be displayed. By displaying the accumulated amount during registration, the store clerk can, for example, appropriately confirm the right to draw a lottery (whether or not the purchase amount exceeds a predetermined amount, etc.), and can prepare for the lottery in advance.

Whether or not to display the product name of the product registered by the customer on the store clerk side display unit 210 in the full self mode in which the store clerk is logged in is determined by the store clerk side (clerk side display unit 210) or the customer side (customer side display unit 205). ) may be set in at least one of them.

The second POS terminal 20 is released from the login state (changes from the login state to the logout state) based on an explicit operation (logout operation) by the clerk. In place of or in addition to the explicit operation by the clerk, when a predetermined time (for example, can be set for each terminal) has passed since the last operation by the clerk (when no operation has been performed for a predetermined time), the login state is canceled. may be made.

Note that the hibernation state (hibernation mode) and the logout state described above may be the same. That is, the logout operation described above is an operation of the pause button. However, the hibernation state and the logout state may be different states. For example, the hibernation state (hibernation mode) may be a part of the login state (the transition state when the pause button is operated in the login state). If the hibernation state and the logout state are regarded as different states, the logout operation is different from the operation of the pause button.

However, for products that require the intervention of a clerk (for example, products that require heating in a microwave oven, products that the clerk takes out (meat buns, cigarettes, etc.)), it is necessary to notify the clerk of the product, so regardless of the above settings , may be displayed on the store clerk side display unit 210 . In addition, since it is necessary to notify the store clerk of products that require age authentication (for example, cigarettes, alcoholic beverages, etc.), they may be displayed on the store clerk-side display unit 210 regardless of the above setting. Whether or not the product or the like requires the intervention of a store clerk may be determined in advance for each product.

Although the embodiments of the present invention have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments, and designs and the like are included within the scope of the present invention.

(Other examples of restricted periods for sending and receiving registration information)
According to FIGS. 19A and 20, the transmission of registration information to the second POS terminal 20 in full self mode is restricted (prohibited) during the period from the registration of one purchased product to the determination of the deposit amount. However, the period during which the transmission of registration information is restricted is not limited to the period described above (although transmission of registration information is not permitted). In other words, the transmission of the registration information to the second POS terminal 20 may be restricted from a timing earlier (or later) than the timing at which one purchased product is registered at the second POS terminal 20 in full self mode. In other words, the second POS terminal 20 may restrict reception of registration information transmitted from other terminals at a timing that is earlier (or later) than the timing for registering one purchased item. Also, the restriction on transmission of registration information to the second POS terminal 20 may be lifted at a timing earlier (or later) than the timing at which the deposit amount is determined at the second POS terminal 20 in full self mode. In other words, the second POS terminal 20 may release the restriction on receiving registration information transmitted from other terminals at a timing earlier (or later) than the timing at which the deposit amount is determined.

Specifically, in FIG. 19A, the second POS terminal 20 transmits the transmission restriction start information after registering one purchased product (step S402). may be sent. In addition, although the second POS terminal 20 transmits the transmission restriction end information after the operation of the end (receipt) button BT40 (step S408) in FIG. 19A, the transmission restriction end information is transmitted at another timing. You may

As an example, the transmission of registration information may be restricted from the timing at which product registration is completed (the timing at which all purchased products have been registered) instead of the timing at which one purchased product is registered. Specifically, the second POS terminal 20 may transmit the transmission restriction start information after the checkout button BT32 is operated (step S402).

As an example, the restriction on transmission of registration information may be lifted from the timing when the released change is removed. Specifically, the second POS terminal 20 may transmit the transmission restriction end information after detection of removal of change (step S411).

Also, the restriction on transmission of registration information may be lifted from the timing when the released receipt is removed. Specifically, the second POS terminal 20 may transmit the transmission restriction end information after detection of receipt removal (step S413).

In the above description, the transmission restriction period for registration information from the first POS terminal 10 to the second POS terminal 20 in full-self mode (in other words, the restriction period for reception of registration information at the second POS terminal 20 in full-self mode) is restricted. Although it has been explained that the period (reception restriction period) is not limited to the period shown in FIG. In other words, the restricted transmission period (restricted reception period) for the registration information in the second POS terminal 20 in the semi-self mode (accounting-only mode) is similarly limited to the period shown in FIG. 19B. not.

(Other control methods for sending and receiving registration information)
19 and 20, the second POS terminal 20 (receiving side of registration information) in full self mode transmits the registration information of the first POS terminal 10 to the first POS terminal 10 (sending side of registration information). By transmitting the control information (transmission restriction start information, transmission restriction end information) for judging whether or not to transmit the registration information in the first POS terminal 10 (that is, whether or not the registration information in the second POS terminal 20 in full self mode receive or not) is controlled. However, the method of controlling whether or not to transmit registration information at the first POS terminal 10 (whether or not to receive registration information at the second POS terminal 20 in full-self mode) is not limited to the examples shown in FIGS.

For example, instead of transmitting control information (transmission restriction start information, transmission restriction end information) from the second POS terminal 20, information (status information) indicating the progress of processing in the second POS terminal 20 (see FIG. 19). , information to the effect that one purchased item has been registered, information to the effect that the checkout button has been pressed, information to the effect that the payment method selection screen has been displayed, etc.) to the first POS terminal 10, It may be possible to control whether or not the first POS terminal 10 can transmit the registration information (that is, whether or not the second POS terminal 20 in the full-self mode can receive the registration information). In other words, the first POS terminal 10 controls whether or not the registration information can be transmitted to the second POS terminal 20 based on the status information received from the second POS terminal 20 (whether or not the registration information can be received by the second POS terminal 20 in full-self mode). may

When the second POS terminal 20 is in a specific operation mode (eg, full-self mode, semi-self mode (accounting-only mode)), terminals other than the first POS terminal 10 (eg, other second POS terminal 20, monitor The above status information may be sent to the terminal 40, store controller 30). As a result, for example, the monitoring terminal 40 can display on the screen the real-time processing status of each of the second POS terminals 20 based on the status information transmitted from each of the second POS terminals 20 . Note that the monitoring terminal 40 may be a mobile terminal (for example, a smart phone, a tablet terminal, a notebook computer, or the like). It should be noted that the status information may be transmitted in all operating modes instead of specific operating modes.

It should be noted that the second POS terminal 20 may vary the granularity (types and number of situations to be transmitted) of status information to be transmitted to other terminals according to the operation mode. For example, the second POS terminal 20 transmits status information at a fine level in one mode (eg, full-self mode) and transmits status information at a coarse level in another mode (eg, semi-self mode (accounting-only mode)). may That is, the second POS terminal 20 in a certain mode (for example, full-self mode) transmits status information that notifies all of the situations shown in FIG. (For example, the second POS terminal 20 in semi-self mode (accounting-only mode)) transmits status information that notifies some of the situations shown in FIG. good too. The granularity of status information to be transmitted (which status should be reported) may be set for each operation mode. It should be noted that the situations shown in FIGS. 19A and 19B are only examples, and other situations may exist.

Further, the second POS terminal 20 may change the granularity of the status information according to the destination terminal of the status information instead of or in addition to the operation mode. For example, status information may be sent to the monitoring terminal 40 at a finer level than other terminals. The granularity of status information may be set for each destination terminal.

The second POS terminal 20 (receiving side of registration information) does not transmit any information to the first POS terminal 10 (transmitting side of registration information), and the first POS terminal 10 simply transmits the registration information. The terminal 20 may determine whether or not reception is possible according to the progress of processing. In other words, the sending side of the registration information unconditionally sends it, and the receiving side decides whether or not to receive it (more specifically, it is received once for the purpose of judgment, but later it is stored in the storage unit, etc., whether or not to accept it). You may When the second POS terminal 20 does not accept the registration information transmitted from the first POS terminal 10, it responds to the first POS terminal 10 with information indicating that the registration information will not be accepted (not taken over). The second POS terminal 20 may respond to the first POS terminal 10 with current status information together with information indicating that the registration information is not accepted.

It should be noted that the next customer may already be waiting in line at the second POS terminal 20 (receiving side of registration information) in full self mode. When the second POS terminal 20 in full self-mode where the next customer is already waiting in line receives the registration information transmitted from the other terminal, the next customer waiting in line and the customer who moves from the other terminal There is also a risk of trouble with the customer who pays based on the registered information regarding the order of processing. Therefore, the second POS terminal 20 in full self mode where the next customer is already waiting in line is controlled so as not to transmit the registration information, or the second POS terminal 20 is in full self mode where the next customer is already waiting in line. Preferably, the second POS terminal 20 is controlled not to receive registration information transmitted from other terminals. However, even if the second POS terminal 20 in full self mode where the next customer is already waiting in line is equipped with a function (forcible transmission button, etc.) to forcibly transmit the registered information in case of an emergency, good. Whether or not the next customer is waiting in line may be monitored by, for example, a camera or various sensors.

In addition, in the second POS terminal 20 in full self mode, when the registration start screen is displayed after the settlement process is completed (that is, when the registration information is not received from the other terminal at the end of the settlement process) ), instead of the full self-mode registration start screen (FIG. 12A), a full self-mode registration screen (initial state registration screen) may be displayed. Specifically, in step S208 of FIG. 17 (the same applies to step S328 of FIG. 18), the second POS terminal 20-1 replaces the full self-mode registration start screen with the full self-mode registration screen (in the initial state). registration screen) may be displayed. That is, the operation of the registration start button BT30 on the registration start screen may be omitted.

In the second POS terminal 20 in full-self mode, it is possible to control whether to display the registration screen or the registration start screen after the settlement process is completed, depending on whether or not the next customer is waiting in line. good. For example, in step S208 of FIG. 17, the second POS terminal 20-1 displays the registration start screen if the next customer is not waiting in line, and displays the registration screen if the next customer is waiting in line. You may That is, the operation of the registration start button BT30 on the next customer's registration start screen may be omitted.

(Mode shift from full self mode to normal mode)
In the above description, the second POS terminal 20 in full-self mode switches from full-self mode to semi-self mode (accounting-only mode) depending on whether or not registration information is received (FIG. 17). The second POS terminal 20 may shift from the full self mode to the normal mode depending on whether or not the registration information has been received. For example, if the second POS terminal 20 in full-self mode stores the registration information received from the other terminal at the end of settlement processing in its own terminal, the operation mode can be changed from full-self mode to normal mode. good.

For example, the second POS terminal 20 in full-self mode controls whether or not to transmit registration information from other terminals to its own terminal (FIG. 19A). The second POS terminal 20 in the full-self mode that has received the registration information may shift to the semi-self mode (accounting-only mode) (FIG. 17) or to the normal mode. In the normal mode, after product registration (registration processing) on the clerk's side is completed, the customer performs settlement processing based on the registration information in the registration processing on the clerk's side (FIG. 6). If you receive the registration information from the other terminal and shift to normal mode, after receiving the registration information from the other terminal, on the customer side, the registration information received from the other terminal (registration information registered on the other terminal) Based on this, settlement processing is performed.

(Mode shift from normal mode to full self mode)
In the above example, the second POS terminal 20 in semi-self mode (accounting only mode) switches from semi-self mode (accounting only mode) to full self mode depending on whether or not registration information is received (FIG. 18). The second POS terminal 20 in the normal mode may also shift from the normal mode to the full self mode depending on whether registration information is received or not. For example, if the second POS terminal 20 in the normal mode does not start product registration (registration processing) for the next customer at the end of the settlement process on its own terminal, the second POS terminal 20 receives the registration received from the other terminal at the end of the settlement process on its own terminal. If the information is not stored, the operating mode may be changed from the normal mode to the full self mode. The second POS terminal 20 in the normal mode has not started product registration (registration processing) of the next customer at the end of settlement processing at its own terminal, and the registration information received from the other terminal at the end of settlement processing at its own terminal. is not stored, and product registration (registration processing) is not started within a predetermined time after the end of the settlement processing, and registration information is not received from another terminal, normal mode The operation mode may be changed from the full self mode to the full self mode.

As described above, the second POS terminal 20 can change the operation mode between the normal mode and the full self mode as well as between the semi-self mode (accounting mode) and the full self mode. is. Note that it is also possible to change between other modes (for example, change the operation mode between the normal mode and the semi-self mode (accounting mode)). Further, as illustrated in FIGS. 18 and 19, it is also possible to switch the display screen according to the changed operation mode according to the change to various operation modes.

In the above, the second POS terminal 20 in full-self mode controls whether or not to transmit registration information from other terminals to its own terminal (FIG. 19A), and the second POS terminal 20 in semi-self mode (accounting-only mode) Although the example (FIG. 19B) in which the terminal 20 controls whether or not to transmit registration information from other terminals to its own terminal has been described, the second POS terminal 20 in the normal mode can also transmit registration information from other terminals to its own terminal. can be controlled. For example, the second POS terminal 20 in normal mode transmits the transmission restriction start information after the start of product registration (after the start of registration of one purchased product), and the end ( The transmission restriction end information may be transmitted after accepting the operation of the receipt button. Note that the transmission timing of the transmission restriction start information and the transmission restriction end information is not limited to the above. For example, in the settlement processing of the last customer including the next customer, the transmission restriction end information may be transmitted after the removal of change is detected or after the removal of the receipt is detected.

(Control method in mode using accounting coupon)
In the above description, the second POS terminal 20 in full-self mode switches from full-self mode to semi-self mode (accounting-only mode) depending on whether or not registration information is received (FIG. 17). The second POS terminal 20 may shift from the full-self mode to the semi-self mode (accounting-only mode) depending on whether or not the accounting ticket issued by the other terminal is read. For example, if the second POS terminal 20 in full-self mode has read an accounting ticket (for example, stores registration information and transaction identification information obtained from the ), you may shift from the full-self mode to the semi-self mode (accounting-only mode).

As described above, when the second POS terminal 20 in full-self mode receives registration information from another terminal, the second POS terminal 20 changes from full-self mode to semi-self mode (accounting-only mode) before executing settlement processing using the registration information. mode) (you may process the registration information received from other terminals as a semi-self mode (accounting-only mode) payment processing), or before executing the payment processing using the registration information It is not necessary to shift from full-self mode to semi-self mode (accounting-only mode) (although it is possible to process registration information received from other terminals as payment processing in full-self mode), but when the accounting ticket is read The same is true for In other words, when the second POS terminal 20 in full-self mode reads an accounting ticket, it switches from full-self mode to semi-self mode (accounting-only mode) before executing settlement processing using the registration information obtained from the accounting ticket. mode) (you may process the registration information obtained from the accounting ticket as a settlement procedure for the semi-self mode (accounting mode)), or the registration information obtained from the accounting ticket It is not necessary to shift from full-self mode to semi-self mode (accounting-only mode) before executing settlement processing using ).

In addition, the second POS terminal 20 in full-self mode may switch from full-self mode to normal mode depending on whether or not an accounting coupon issued by another terminal is read. For example, if the second POS terminal 20 in full-self mode has read the accounting ticket by the end of the settlement process on its own terminal, it will read the registration information received from the other terminal at the end of the settlement process on its own terminal. You may switch from the full self mode to the normal mode as in the case of memorization.

When the second POS terminal 20 in full-self mode reads an accounting ticket, it switches from full-self mode to normal mode before executing settlement processing using the registration information obtained from the accounting ticket. (Although the registration information obtained from the accounting coupon may be processed as a settlement procedure in the normal mode), before executing the settlement processing using the registration information obtained from the accounting voucher It is not necessary to shift from the self-mode to the normal mode (the registration information obtained from the accounting coupon may be processed as a settlement procedure in the full-self mode).

In the above example, the second POS terminal 20 in semi-self mode (accounting only mode) switches from semi-self mode (accounting only mode) to full self mode depending on whether or not registration information is received (FIG. 18). In place of or in addition to the shift depending on whether the registration information is received or not, the second POS terminal 20 in the semi-self mode (accounting-only mode) performs the semi-self You may shift from the mode (accounting-only mode) to the full self mode. For example, if the second POS terminal 20 in semi-self mode (accounting only mode) has not read the accounting ticket by the end of the settlement process (for example, registration information and transaction identification information obtained from the read accounting ticket is not memorized), the semi-self mode (accounting mode) may be switched to the full self mode. Further, for example, the second POS terminal 20 in semi-self mode (accounting-only mode) has not read the accounting ticket by the end of the settlement process, and has not completed the accounting within a predetermined time after the end of the settlement process. If the ticket is not read, the operation mode may be changed from the semi-self mode (accounting mode) to the full self mode.

In the above description, the second POS terminal 20 in the normal mode switches from the normal mode to the full self mode depending on whether the registration information is received or not. Alternatively or additionally, the second POS terminal 20 in the normal mode may shift from the normal mode to the full self mode depending on whether or not the accounting coupon issued by the other terminal is read. For example, the second POS terminal 20 in the normal mode has not yet started product registration (registration processing) for the next customer at the end of settlement processing on its own terminal, and the accounting ticket is not read, the normal mode may be switched to the full self mode. Further, for example, the second POS terminal 20 in the normal mode has not yet started product registration (registration processing) for the next customer at the end of the settlement process on its own terminal, and the transaction is completed before the end of the settlement process on its own terminal. If the ticket has not been read, nor has product registration been started and the accounting ticket has not been read within a predetermined time after the end of the settlement process, the operating mode is changed from normal mode to full self mode. may

As described above, the second POS terminal 20 can change the operation mode based on whether or not the accounting ticket has been read, as well as the change of the operation mode based on whether or not the registration information has been received.

In the above description, the reading control of various identification information (product code, member identification information, privilege identification information, etc.) by the second POS terminal 20 (customer side scanner unit 206, store clerk side scanner unit 212) has been described (Fig. 21), the second POS terminal 20 may always permit the reading of accounting coupons in any operation mode, and in both the customer-side scanner unit 206 and the store clerk-side scanner unit 212 . However, if there is already registration information waiting to be processed (for example, if registration information received from another terminal is already stored, registration information and transactions obtained from another accounting ticket read in advance) If the identification information is already stored), the reading of the accounting ticket may be prohibited (and a message indicating that reading is not possible because there is already registration information waiting to be processed) may be displayed.

Note that the second POS terminal 20 may control the reading of accounting coupons according to the operation mode, processing status, and the like. For example, when the customer side is vacant (for example, when there is no customer on the customer side in semi-self mode (accounting mode) or full self mode), the customer side scanner unit 206 is permitted to read the accounting ticket, When the customer is not available (for example, in the normal mode, when there is a customer on the customer side in the semi-self mode (accounting mode), or in the full self mode), the customer scanner unit 206 scans the accounting ticket. may be prohibited. However, even if the customer is vacant, if there is already registration information waiting to be processed, the customer-side scanner unit 206 is prohibited from reading the accounting ticket (furthermore, if the registration information waiting to be processed is A message indicating that the file cannot be read because it already exists may be displayed).

If there is an accounting ticket that has not been read yet in the store, the scanning of the accounting ticket by the customer-side scanner unit 206 is permitted. may prohibit the customer-side scanner unit 206 from reading the accounting ticket. In other words, the reading of the accounting ticket by the customer-side scanner unit 206 may be permitted only during the period from the issuance of a certain accounting ticket until the said accounting ticket is read by any terminal. As described above, when the customer is vacant and there is an accounting ticket in the store that has not yet been read, the customer-side scanner unit 206 is permitted to read the accounting ticket. If there is no accounting ticket available or there is no accounting ticket that has not been read yet in the store, the reading of the accounting ticket by the customer-side scanner unit 206 may be prohibited. It should be noted that, for example, the store controller 30 may manage whether or not there is an accounting ticket that has not yet been read in the store. For example, when the second POS terminal 20 issues an accounting ticket, it sends issuance information (for example, identification information for identifying each accounting ticket, issuing time, etc.) to the store controller 30, and reads the accounting ticket. By transmitting read information (for example, identification information for identifying individual accounting tickets, reading time, etc.) to the store controller 30, the store controller 30 can detect the presence of unread accounting tickets in the store. More specifically, the store controller 30 determines whether or not an accounting ticket that has not yet been read exists in the store if there is an accounting ticket for which only the issuance information is stored. If it is determined that there is no accounting ticket in which only the issuance information is stored, it is determined that there is no accounting ticket that has not been read yet in the store.

In addition, the reading of the accounting ticket by the clerk-side scanner unit 212 may be controlled in the same manner as the reading of the accounting ticket by the customer-side scanner unit 206 (when the customer-side scanner unit 206 reads the accounting ticket, If it is permitted, the clerk side scanner unit 212 is allowed to read the accounting ticket, and if the customer side scanner unit 206 is prohibited from reading the accounting ticket, the clerk side scanner unit 212 reads the accounting ticket However, in consideration of operational convenience, even if the customer-side scanner unit 206 is prohibited from reading the accounting ticket, the clerk-side scanner unit 212 cannot read the accounting ticket. may be allowed to read.

(Control method in recall processing)
In the POS system 1, after the transfer from the registration side to the settlement side, it is possible to perform processing (recall back processing) to return to the registration side for the purpose of changing purchased products (cancellation, addition, change). Note that the recall process includes, for example, a predetermined operation by a store clerk (for example, an operation to designate the transaction from the registration side and declare the recall, an operation to declare the recall from the settlement side, an operation to designate the transaction from the monitoring terminal 40, etc.). operation that declares a recall, etc.). The operation mode transition related to recall processing will be described below.

For example, the second POS terminal 20 in full-self mode receives registration information from another terminal (or reads an accounting ticket issued by the other terminal), and shifts from full-self mode to semi-self mode (accounting-only mode). Later, when recall processing is performed, the registration information on the payment side (registration information in the second POS terminal 20) is returned to the registration side (the terminal that performed the product registration related to the registration information. terminal that sent the information, or the terminal that issued the accounting ticket). That is, when the recall process is performed, the recalled registration information is moved (returned) from the settlement side to the registration side.

If the second POS terminal 20 in semi-self mode (accounting mode) that has undergone recall processing stores the following registration information (in addition to the registration information moved to the registration side, the registration information received from another terminal or if you store the registration information and transaction identification information obtained from the accounting ticket), while maintaining the semi-self mode (accounting-only mode), settlement processing based on the next registration information to run. On the other hand, if the second POS terminal 20 in the semi-self mode (accounting only mode) that has undergone the recall process does not store the next registration information, etc., it immediately or for a predetermined period of time without obtaining the next registration information. has passed, the semi-self mode (accounting mode) may be shifted to the full self mode.

Also, for example, the second POS terminal 20 in full-self mode receives registration information from another terminal (or reads an accounting ticket issued by the other terminal), shifts from full-self mode to normal mode, and then performs call-back processing. is performed, the second POS terminal 20 in the normal mode that has undergone the recall process, if it stores the next registration information etc., maintains the normal mode and returns to the next registration information. If product registration has been started on the registration side of the own terminal, the settlement processing based on the registration information of the own terminal is executed while maintaining the normal mode. On the other hand, if the second POS terminal 20 in the normal mode that has undergone the recall process does not store the next registration information, etc., or if product registration has not started on the registration side of its own terminal, immediately or Alternatively, the normal mode may be switched to the full self mode when a predetermined period of time has elapsed without obtaining the next registration information.

As described above, the operation mode can be changed based on the recall process being performed. Specifically, by receiving registration information from another terminal when in full-self mode (or by reading an accounting ticket issued by another terminal), another operation mode (semi-self mode (accounting only) mode), normal mode), if recall processing is performed and there is no other registration information that can be processed, immediately or for a predetermined period of time without obtaining the next registration information When the time elapses, the operation mode can be changed from other operation modes (semi-self mode (accounting mode), normal mode) to the original operation mode (full self mode).

Note that it is not necessary to change the operation mode back to the original operation mode after executing the recall process. For example, the operation mode may be changed to an operation mode different from the original operation mode after executing the recall process. For example, by receiving registration information from another terminal in normal mode (or by reading an accounting ticket issued by another terminal), after shifting to semi-self mode (accounting mode), recall processing is performed and there is no other registration information that can be processed, immediately or after a predetermined time has passed without obtaining the next registration information, from semi-self mode (accounting only mode) The operation mode may be changed to the full self mode without changing to the normal mode, which is the original operation mode.

Also, it is not necessary to change the operation mode after executing the recall process. For example, by receiving registration information from another terminal in normal mode (or by reading an accounting ticket issued by another terminal), after shifting to semi-self mode (accounting mode), recall processing is performed, even if there is no other registration information that can be processed and a predetermined time has passed without obtaining the next registration information, the operation mode is not changed and the semi-self mode ( accounting-only mode) may be maintained.

In the operation for executing the recall process, the store clerk can specify whether or not to change the operation mode after the recall process is executed, and the operation mode after the recall process is executed (that is, which operation mode to change to). can be

In addition, recall processing can be performed before or after payment (for example, before the end (receipt) button is operated, even after payment). When the recall process is performed after depositing, the recall process is performed after withdrawing the full amount deposited (or the full amount deposited as part of the recall process is withdrawn).

In the above description, when the recall process is performed, the recalled registration information is moved (returned) from the settlement side to the registration side. It is not necessary to delete the registration information of For example, on the settlement side, by adding information indicating that the information is recalled (such as a flag indicating that it is recalled) to the registered information that is subject to recall, the registered information that is subject to recall can be recalled after the recall process. The settlement action used may not be performed.

(Control method for operation mode, etc. based on other events)
Change the operation mode or switch the display screen based on receiving registration information from other terminals, reading accounting tickets issued by other terminals, or performing recall processing. However, the operation mode may be changed or the display screen may be switched based on other events. Specifically, when the registration information used for settlement processing is to be acquired soon, the operation mode may be changed or the display screen may be switched. For example, requesting the registration information from a terminal storing the registration information (for example, the second POS terminal 20 that executed the registration process, the store controller 30 that acquired the registration information from the second POS terminal 20 that executed the registration process, etc.). or receiving information (also known as notice information or notice flag) indicating that the registration information will be sent soon from a terminal that stores the registration information, etc. You can An example of the notice information is, for example, when it is determined that the destination of the registration information is the own terminal (for example, when the own terminal is prioritized over other terminals based on the processing status, etc., or when the change is insufficient). (e.g., when settlement processing cannot be performed on a terminal other than the own terminal due to the situation of the registration side), when it is determined that the registration side will soon specify the terminal that will execute the settlement processing (that is, specify the own terminal) (the subtotal button is operated on the registration side This information is transmitted (announced) when

In addition, it constantly monitors whether there is registration information to be processed in its own terminal or at a predetermined timing (for example, inquires to other terminals), and when it recognizes that there is registration information to be processed in its own terminal, it operates The mode may be changed or the display screen may be switched.

In addition, when the state in which payment processing was performed on another terminal changes to a state in which payment processing is not performed on the other terminal (when a change in the relevant state is detected, for example, a notification or inquiry to another terminal ), the operation mode may be changed or the display screen may be switched. For example, when all three terminals including your terminal are in normal mode, and two other terminals are in semi-self mode (registration-only mode), change your terminal to semi-self mode (accounting-only mode). good too.

In addition, the registration side (the sender of the registration information) transmits the status monitoring data, writes each status while sequentially transferring it to other terminals, and when all writing is completed, the priority (machine number, movement distance, change A terminal to which registration information is to be transmitted may be determined according to the order of priority based on the number of remaining bills, etc.). When the registration side determines one terminal to transmit the registration information, the store clerk does not specify the terminal to transmit the registration information. In addition, the other terminal, which is the receiving side of the registration information, also acquires the status monitoring data, and determines to which terminal the registration information is sent based on the same priority as the registration side, or whether the own terminal receives the registration information. By judging whether or not the information is transmitted prior to the registration side's judgment or substantially at the same time as the registration side's judgment, the operation mode can be changed or the display screen can be switched before the registration information is actually received. You may

(Other controls in full self mode)
Security may be strengthened (improper use prevention measures may be strengthened) in the full-self mode in which a store clerk does not intervene. Specifically, for example, the second POS terminal 20 in full-self mode may be configured so that it cannot be operated by the customer unless the member is authenticated. In other words, when the second POS terminal 20 operates in the full-self mode, it may request member authentication when starting individual transactions (product registration). A form of displaying a registration start screen (Fig. 12(A)) as a screen at the start of each transaction (product registration), and a mode of displaying a registration screen (initial registration screen) without displaying the registration start screen. Although two aspects of aspects have been described, each may be as follows.

In the case of a configuration in which the registration start screen is displayed as the start screen for each transaction (product registration), the second POS terminal 20 in full self-mode may, for example, read the bar code attached to the membership card or the like. In the customer-side display unit 205, a message is displayed on the registration start screen to the effect that the barcode attached to the membership card or the like is to be read, and the registration start button BT30 is disabled (for example, the button is grayed out). (down display, non-display, etc.), and the registration start button BT30 may be operated when the barcode is read. In addition, for example, the second POS terminal 20 in full self mode causes the customer-side display unit 205 to read the barcode attached to the membership card before reading the barcode attached to the membership card. A member authentication screen displaying a message to that effect may be displayed, and when the bar code is read, the display may be switched from the member authentication screen to the registration start screen (the registration start button BT30 can be operated). Membership authentication may be performed by methods other than reading barcodes attached to membership cards, etc. It may be based on a method not used (for example, input of member number, etc., biometrics authentication, etc.).

The same applies to the case of displaying a registration screen (registration screen in an initial state) as a screen at the start of each transaction (product registration). For example, before reading the barcode attached to the membership card or the like, a message to read the barcode attached to the membership card or the like is displayed on the registration screen (registration screen in the initial state) on the customer-side display unit 205. is displayed, reading by the customer-side scanner unit 206 and operation of the preset button (“Vegetables” button BT38, etc.) are disabled, and when the barcode is read, reading by the customer-side scanner unit 206 and operation of the preset button are disabled. may be made possible. Further, for example, the second POS terminal 20 in full self mode displays the above-described member authentication screen before reading a barcode attached to a membership card or the like, and displays the member authentication screen when the barcode is read. The display may be switched from the screen to the registration screen (registration screen in the initial state).

It should be noted that member authentication may be turned on/off manually or automatically. For example, in the POS system 1, the late-night time zone is set in advance (for example, the setting contents are stored in the store controller 30), and the second POS terminal 20 in the full self-mode is currently in the late-night time zone. Member authentication may be turned on at certain times, and turned off when the current date and time are not in the middle of the night. In other words, the second POS terminal 20 in the full-self mode cannot be used automatically when entering the late-night time zone without member authentication, and when leaving the late-night time zone, the full-self mode automatically becomes available without member authentication. mode, the second POS terminal 20 may be made available. Member authentication may be turned on when the clerk is not near the second POS terminal 20 in full self mode (for example, determined by a sensor or the like), and turned off when the clerk is near. . Also, member authentication may be turned on only when it is late at night and there is no store clerk nearby, or member authentication may be turned off only when there is a store clerk nearby instead of late at night. Good.

Instead of or in addition to the viewpoint of strengthening security (strengthening measures to prevent unauthorized use), incentives may be given to the use of full self from the viewpoint of promoting the use of full self. For example, the benefits provided by the second POS terminal 20 in the full self mode may be more advantageous to the customer than the benefits provided by the second POS terminal 20 in other modes. In other words, the second POS terminal 20 does not allow the member specified from the membership card or the like to receive other information when the member is in the full self mode even if other conditions such as the total amount of purchases made this time and past purchase records are the same. You may make it give more privilege than when in mode.

(Configuration of POS system)
Note that the first POS terminal 10 in the POS system 1 shown in FIG. may be In other words, it may be a general POS terminal.

The POS system 1 shown in FIG. 1 includes one first POS terminal 10 and two second POS terminals 20 as POS terminals, but the configuration of the POS terminals is not limited to this. Specifically, the number of first POS terminals 10 may be zero (not included) or two or more, and the number of second POS terminals 20 may be one or three or more. For example, if the POS terminal does not include the first POS terminal 10 but includes three second POS terminals 20 (that is, instead of the one first POS terminal 10 in the POS system 1 shown in FIG. 1, one (in the case of a POS system in which the second POS terminal 20 is arranged), various operations are conceivable. Some examples are given below.

For example, one second POS terminal 20 is operated in normal mode, and the other two second POS terminals 20 are operated in full self mode. dedicated mode). In other words, by transmitting the registration information registered by the clerk at the second POS terminal 20 in the normal mode to the second POS terminal 20 in the full self mode, the second POS terminal 20 to which the registration information is sent is changed from the full self mode to the semi self mode (accounting mode). dedicated mode).

Also, for example, all three machines are operated in the full self mode, and depending on the situation, some machines are switched to an operation mode (normal mode, double scan mode) in which the store clerk supports product registration.

Also, for example, operate one in full-self mode and the other two in semi-self mode (one of them is registration-only mode, the other one is accounting-only mode), and depending on the situation, switch to full-self mode A store clerk switches one unit to an operation mode (normal mode, double scan mode) that supports product registration.

Further, for example, all three terminals are operated in the normal mode, and depending on the situation, several terminals are switched to the semi-self mode (accounting exclusive mode) in which the customer pays with another terminal. Note that control of switching from the normal mode to the semi-self mode (accounting mode) may be the same control as switching from the full self mode to the semi-self mode (accounting mode). In other words, in the full self mode, the customer registers the product, whereas in the normal mode, the store clerk registers the product. later), you can switch from the normal mode to the semi-self mode (accounting mode). In other words, by transmitting the registration information registered by the clerk at the second POS terminal 20 in the normal mode to the other second POS terminal 20 in the normal mode, the second POS terminal 20 to which the registration information is sent is changed from the normal mode to the semi-self mode (accounting mode). dedicated mode).

Furthermore, the configuration of the POS system may include a product registration dedicated terminal and a settlement dedicated terminal. For example, the configuration may include one dedicated product registration terminal and three second POS terminals 20 . In the case of this configuration, of the three second POS terminals 20, for example, one may be in full-self mode or normal mode, and two may be in semi-self mode (accounting-only mode). Alternatively, the configuration may include two second POS terminals 20 and one settlement-dedicated terminal. In the case of this configuration, of the two second POS terminals 20, for example, one may be in full-self mode or normal mode, and one may be in semi-self mode (registration-only mode). Alternatively, the configuration may include one product registration dedicated terminal, one second POS terminal 20, and one settlement dedicated terminal. In the case of such a configuration, one second POS terminal 20 may be in a semi-self mode (accounting-only mode) during normal times, for example.

FIG. 22 is an explanatory diagram illustrating a send button for sending registration information. Specifically, each of FIGS. 22(A) to 22(C) shows a part of a registration screen ( lower right part).

The scenes shown in FIGS. 22A to 22C are different from those in FIG. Specifically, FIG. 14 shows one second POS terminal 20 (semi-self mode (registration only mode) in a configuration in which there are two second POS terminals 20 (second POS terminal 20-1, second POS terminal 20-2). is a display example of the second POS terminal 20-1). On the other hand, in each of FIGS. 22A and 22B, there are three second POS terminals 20 (assumed to be second POS terminal 20-1, second POS terminal 20-2, and second POS terminal 20-3). This is a display example of one second POS terminal 20 (second POS terminal 20-1 in semi-self mode (registration only mode)) in the existing configuration. FIG. 22(C) shows a configuration in which there are three second POS terminals 20 (assumed to be a second POS terminal 20-1, a second POS terminal 20-2, and a second POS terminal 20-3). This is a display example of the 2POS terminal 20 (second POS terminal 20-1 in normal mode).

The second POS terminal 20 may indicate the state (status) of the destination terminal using the send button for sending the registration information.

For example, when the second POS terminal 20-1 runs out of receipt paper for the second POS terminal 20-2 in semi-self mode (accounting-only mode), which is one of the candidates for the transmission destination of the registration information (it will run out soon). 22(A), in association with the 20-2 checkout button BT22 corresponding to the second POS terminal 20-2 (for example, above the 20-2 checkout button BT22 ), an image GA10 indicating that the receipt is insufficient may be displayed. Information about the remaining amount of receipt paper at each terminal may be shared within the POS system. That is, for example, when one terminal runs out of receipt paper, information indicating the shortage of receipt paper may be sent to the other terminals (all other terminals including the monitoring terminal 40). The same applies to information about change.

Further, when the second POS terminal 20-1 cannot communicate with the second POS terminal 20-3 in semi-self mode (accounting mode), which is one of the candidates for the transmission destination of the registration information, ), in association with the 20-3 register button BT22 corresponding to the second POS terminal 20-3), an image GA11 indicating that the terminal is offline may be displayed. Whether or not communication is possible (whether offline) may be determined, for example, by periodically transmitting/receiving information for confirming whether or not communication is possible.

Incidentally, in FIG. 22A, the hatched line above the 20-3 register button BT22 indicates that the registration information cannot be transmitted to the second POS terminal 20-3. In FIG. 14, it has been explained that the buttons whose operation is not valid are displayed differently (for example, grayed out), but they may be shaded as described above. The same applies to FIGS. 22(B) and 23(C).

In addition, the second POS terminal 20-1, when the second POS terminal 20-2 in semi-self mode (accounting-only mode), which is one of the candidates for the transmission destination of the registration information, runs out of change (one denomination) ( Alternatively, if the amount is insufficient to make it difficult to process the next customer's payment (determined by a threshold value), as shown in FIG. image GA12 may be displayed.

In addition, the second POS terminal 20-1 is almost overflowing with the change (one denomination) of the second POS terminal 20-3 in semi-self mode (accounting mode), which is one of the candidates for the transmission destination of the registration information. 22B, an image GA14 indicating that the change is about to overflow may be displayed in association with the 20-3 register button BT23, as shown in FIG. 22(B). . In addition, when maintenance is in progress (in this case, maintenance for discharging change that seems to be overflowing), as shown in FIG. Image GA19 may be displayed.

Further, if the second POS terminal 20-1 is one of the candidates for the transmission destination of the registration information, and the second POS terminal 20-2 in the full-self mode is overflowing with change (one denomination), As shown in FIG. 22C, an image GA14 indicating that change is about to overflow may be displayed in association with the 20-2 register button BT22.

Further, the second POS terminal 20-1 restricts the transmission of registration information to the second POS terminal 20-3 in the full-self mode, which is one of the candidates for the transmission destination of the registration information. 20), as shown in FIG. 22C, an image GA18 indicating that transmission of registration information is restricted may be displayed in association with the 20-3 register button BT23.

14, the change status button BT27 shown in FIGS. 22A to 22C confirms the status of the change machine 209 of the own terminal (second POS terminal 20-1). (button for displaying the number of sheets for each denomination). In addition, when the change (one denomination) of the own terminal is insufficient (when it is almost exhausted, determined by a threshold value), as shown in FIG. An image GA20 indicating that the change is insufficient may be displayed. By displaying the image GA20, it is possible to prompt the operation of the change status button BT27 (confirmation of the number of coins for each denomination, etc.).

If the accounting coupon cannot be issued (for example, if the paper is out of paper, etc.), the operation of the accounting coupon button BT25 is not valid, that is, the mode that the accounting coupon cannot be issued (grayed down, ) may be displayed.
