(Overview of each operation mode)
Next, the operation mode of the POS terminal 20 will be described. The POS terminal 20 has a plurality of operation modes. For example, the POS terminal 20 has a normal mode, a full self mode, and a semi self mode. The operation mode described below is an operation mode during normal business (operation mode relating to product registration processing and accounting processing), and is an aggregation mode for totalizing and inquiring sales and occupancy, etc. It does not include a maintenance mode for performing setting work or maintenance work, a training mode for newcomer training, and the like.

  4 to 6 are diagrams for explaining the outline of the operation mode of the POS terminal 20. FIG. FIG. 4 is a diagram illustrating an outline of the normal mode. FIG. 4A is a schematic diagram showing the flow of processing (product registration processing, accounting processing) and the operation of a person (store clerk, customer) in the normal mode, and FIG. 4B is a schematic diagram of the POS terminal 20 in the normal mode. 6 is a flowchart illustrating a basic flow of an operation. FIG. 5 is a diagram schematically illustrating the full self mode. FIG. 5A is a schematic diagram showing the flow of processing (product registration processing, accounting processing) and the operation of a person (customer) in the full self mode, and FIG. 5B is a diagram of the POS terminal 20 in the full self mode. 6 is a flowchart illustrating a basic flow of an operation. FIG. 6 is a diagram schematically illustrating the semi-self mode. FIG. 6A is a schematic diagram showing the flow of processing (product registration processing, accounting processing) and the operation of a person (customer) in the semi-self mode, and FIGS. 6B and 6C are figures in the semi-self mode. 4 is a flowchart showing a basic flow of an operation of the POS terminal 20.

  In the following description, as a different aspect from the above-described classification of the operation modes (the normal mode, the full self mode, and the semi self mode), the POS terminal 20 sets the mode in which the product registration process is executed to the registration mode and the settlement process. The execution mode may be referred to as an accounting mode.

(Normal mode)
The normal mode is an operation mode in which a clerk performs a registration process and a customer performs a settlement process, as shown in FIG. That is, as shown in FIG. 4B, in the normal mode, the clerk enters the registration mode, and the customer enters the accounting mode. That is, the POS terminal 20 operates in the registration and accounting mode when viewed from the entire registration processing to the settlement processing.

  In the case of the normal mode, the clerk registers the purchased product of the customer on the clerk side (the clerk side scanner section 212, the clerk side display section 210, the key operation section 211). That is, the POS terminal 20 executes the registration process of the purchased product by the operation of the clerk (operation of the clerk-side scanner unit 212, the clerk-side display unit 210, the key operation unit 211, and the like) (the upper part of FIG. 4A). .

  When the registration process by the clerk is completed, the customer checks the total price of the purchased merchandise on the clerk-side display unit 210, inserts money into the change machine 209, or operates the card settlement unit 208 to make a payment (FIG. 4). (A) lower). That is, the POS terminal 20 executes the settlement process by a customer operation or the like (insertion of money into the change machine 209, operation of the card settlement unit 208) (the lower part of FIG. 4A).

  That is, in the normal mode, as shown in FIG. 4B, the salesclerk first scans the product by the salesclerk-side scanner unit 212, for example (step S10: YES), and registers the product (step S11). After pressing a subtotal key (for example, a subtotal key displayed on the clerk side display unit 210 or a subtotal key arranged on the key operation unit 211) (step S30: YES), the customer side, for example, the change machine 209 (Step S50), and the process is completed. In step S30, the subtotal key is an operation key for completing the registration process, and may be referred to as a subtotal button, a registration completion key, a registration completion button, a checkout key, a checkout button, or the like.

  The customer may wait until the clerk completes the registration process (until the total amount is determined), or may put money into the change machine 209 before the registration process is completed. That is, the POS terminal 20 can accept payment during the registration process (the upper part of FIG. 4A).

  The clerk may wait until the customer completes the payment (until the customer takes a change or receipt), or may register the next customer's purchased product. In other words, the POS terminal 20 can register the purchased product of the next customer during the settlement process (the lower part of FIG. 4A). Also, the clerk may be absent during the checkout by the customer (lower part of FIG. 4A). That is, during the checkout of the customer, the reception of the customer may be ended.

  In addition, when there is change, the POS terminal 20 controls the dispensing of change and bills by the change machine 209 to prevent forgetting to take the change, and a sensor or the like detects that the customer has removed the change or bill. , And controls the printing unit 213 to issue a receipt. The same applies to other operation modes. As described above, in the normal mode, there may be a case where a clerk is present in front of a customer who receives change, and when there is a clerk, it is not always necessary to perform the above-described control (ie, change). -Payment of a bill and issuing of a receipt may be performed at the same time, or a receipt may be issued first). In addition, the timing of paying out change and bills and issuing a receipt may be controlled in accordance with 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)
The full self mode is an operation mode in which a customer performs a registration process and a customer performs a settlement process, as shown in FIG. That is, as shown in FIG. 5 (B), in the case of the full self mode, the customer enters both the registration mode and the accounting mode. That is, the POS terminal 20 operates in the registration and accounting mode when viewed from the entire registration processing to the settlement processing.

  In the case of the full self mode, the customer registers the purchased product on the customer side (the customer side scanner unit 206 and the customer side display unit 205). That is, the POS terminal 20 executes the registration process of the purchased product by the operation of the customer (scan by the customer-side scanner unit 206, touch on the customer-side display unit 205) (the upper part of FIG. 5A).

  When the registration process is completed, the customer checks the total price of the purchased merchandise on the customer-side display unit 205, inserts money into the change machine 209, or operates the card settlement unit 208 to make a payment (FIG. 5A ) Lower row). That is, the POS terminal 20 executes the settlement process by a customer operation or the like (insertion of money into the change machine 209, operation of the card settlement unit 208) (the lower part of FIG. 5A).

  That is, in the full self-mode, as shown in FIG. 5B, on the customer side, for example, a product is scanned by the customer-side scanner unit 206 (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 side performs settlement by, for example, the change machine 209 (step S50). Is completed. The registration completion key according to step S40 is an operation key for completing the registration process, and may be referred to as a registration completion button, a subtotal key, a subtotal button, a checkout key, a checkout button, or the like.

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

  A transition condition from another operation mode to the double scan mode may be settable. Examples of the transition condition include a clerk code input and a password input. By setting the transition condition, it is possible to prevent an erroneous operation from the clerk. Further, whether to execute the double scan mode may be set. In this case, if it is set not to execute the double scan mode, no operation in the double scan mode is permitted. The transition conditions and whether or not the double scan mode can be executed may be set as initial settings.

(Semi-self mode)
The semi-self mode is distinguished between a registration-only mode in which a clerk performs registration processing and an accounting-only mode in which a customer performs payment processing. In the example of FIG. 6, the POS terminal 20-1 operates in the registration-only mode, and the POS terminal 20-2 operates in the accounting-only mode.

  In the case of the semi-self mode, the clerk uses the POS terminal 20-1 in the registration-only mode to register the purchased product of the customer on the clerk side (the clerk side scanner section 212, the clerk side display section 210, the key operation section 211). In other words, the POS terminal 20-1 executes the registration process of the purchased product by the operation of the clerk (operation of the clerk-side scanner unit 212, the clerk-side display unit 210, the key operation unit 211, and the like) (see FIG. 6A). Upper).

  When the registration process by the clerk is completed, the customer moves to the POS terminal 20-2 in the accounting-only mode, checks the total price of the purchased product on the clerk-side display unit 210, and inserts money into the change machine 209, or The card settlement unit 208 is operated to perform the settlement (lower part in FIG. 6A). That is, the POS terminal 20-2 executes the settlement process by a customer operation or the like (insertion of money into the change machine 209, operation of the card settlement unit 208) (the lower part of FIG. 6A).

  When the registration process is completed at the POS terminal 20 in the registration-only mode (the POS terminal 20-1 in the example of FIG. 6), the customer moves from the POS terminal 20 in the registration-only mode to the POS terminal 20 in the accounting-only mode (the example in FIG. 6). Then, the user moves to the POS terminal 20-2), but information (registration information and the like) necessary for the settlement process is supplied to the destination POS terminal 20.

  A method of supplying information necessary for the settlement process from the POS terminal 20 in the registration only mode (the POS terminal 20-1 in the example of FIG. 6) to the POS terminal 20 in the accounting only mode (the POS terminal 20-2 in the example of FIG. 6). A method for transmitting information required for the settlement process from the POS terminal 20 in the registration only mode to the POS terminal 20 in the accounting only mode (may be transmitted via the store controller 30; the same applies hereinafter), a registration only mode The POS terminal 20 issues a medium (a medium on which a barcode or the like for acquiring information necessary for settlement processing is printed).

In the example of FIG. 6, there is only one POS terminal 20 in the accounting-only mode (POS terminal 20-2). However, if there are two or more POS terminals 20 in the accounting-only mode, Alternatively, the POS terminal 20 (POS terminal 20 in the accounting-only mode) for executing the settlement process may be designated in the POS terminal 20 in the registration-only mode (the POS terminal 20-1 in the example of FIG. 6).
When the POS terminal 20 in the registration-only mode issues a medium (medium on which a barcode or the like for acquiring information necessary for the payment processing is printed), the POS terminal 20 in the accounting-only mode reads the medium. The settlement process is executed in the terminal 20.

  That is, in the semi-self mode, first, the clerk of the POS terminal 20 (POS terminal 20-1) in the registration-only mode registers a product. For example, as shown in FIG. 6B, the merchandise is registered by scanning with the clerk-side scanner unit 212 (step S10: YES) (step S11). After pressing a subtotal key (for example, a subtotal key displayed on the clerk side display unit 210 or a subtotal key arranged on the key operation unit 211) (step S30: YES), for example, the POS terminal 20 ( When the POS terminal 20-2) is specified (step S31: YES), the registration information is transmitted to the specified POS terminal 20 (step S32), and the process is completed.

  In the example of FIG. 6B, the processing procedure is such that the subtotal key is pressed at the end of the product registration, and then the POS terminal 20 is specified (after the subtotal key is pressed). Sometimes, the processing procedure may be such that the POS terminal 20 is specified directly (without pressing the subtotal key). In the latter case, the subtotal key need not be displayed on the screen.

  Subsequently, as shown in FIG. 6C, the POS terminal 20 (POS terminal 20-2) designated by the POS terminal 20 (POS terminal 20-1) in the registration only mode receives the registration information (step S1). (S49: YES), the customer makes a settlement by, for example, the change machine 209 (step S50), and the process is completed.

  Note that, after transmitting the registration information (or after issuing the medium), the clerk can register the purchased product of the next customer (the lower part of FIG. 6A). After transmitting the registration information, the clerk may be absent (lower part of FIG. 6A).

  In the example of FIG. 6, the POS terminal 20-2 in the accounting-only mode uses the registration information of the product registered in the POS terminal 20-1 in the registration-only mode to execute the settlement process. That is, the registration information used by the POS terminal 20-2 in the accounting-only mode for the payment process is the registration information of the product registered when the POS terminal 20-1 operates in the registration-only mode. However, if the registration information can be transmitted to the POS terminal 20-2 in the accounting-only mode (or if the voucher can be issued), the registration information used by the POS terminal 20-2 in the accounting-only mode for the settlement process is However, the information does not necessarily have to be the registration information of the product registered when the POS terminal 20-1 operates in the registration only mode.

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

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

  In the example of FIG. 6, the POS terminal 20-2 receives the registration information (or reads the bill) and performs the settlement process when operating in the accounting-only mode. However, if the settlement process can be executed after receiving the registration information (or after reading the bill), the operation when the POS terminal 20-2 receives the registration information (or reads the bill) The mode need not necessarily be the accounting-only mode.

  As an example, when operating in the full self mode, the POS terminal 20-2 receives registration information from the POS terminal 20-1 and executes a checkout process using the registration information received from another terminal. Good. Note that the POS terminal 20-2 shifts from the full self mode to the accounting-only mode before executing the settlement process using the registration information received from the other terminal (the registration received from the other terminal as the accounting process in the accounting-only mode). Process information). Note that the POS terminal 20-2 may or may not shift from the full self mode to the accounting only mode before executing the payment process using the registration information received from another terminal (as a payment process in the full self mode). The registration information received from another terminal may be processed).

(Transition of operation mode)
The POS terminal 20 operates according to an explicit mode shift operation by a clerk (for example, an input on the screen, a selection operation, etc.), and another operation other than the explicit mode shift operation by a clerk (for example, reading of a clerk code). The mode changes. The POS terminal 20 operates in an operation mode based on predetermined conditions that do not depend on the operation of the clerk (conditions related to time such as an elapsed time or a predetermined time (schedule), conditions related to transmission / reception of information with another terminal or the like). Will migrate.

  Next, selection of a settlement method before a declaration of completion of registration of a product to be purchased by a customer (before pressing a subtotal key, during product registration) will be described. FIGS. 7, 8, 9 and 10 are diagrams showing screens displayed on the customer side display unit 205 during registration of a product in the normal mode. FIG. 7A is a diagram showing a screen 1 for selecting a settlement method. Screen 1 is a screen displayed immediately after the start of registration. The screen 1 displays an advertisement area 301, a settlement method selection area 351, a registered product display area 302, and a total price display area 303.

  An advertisement is displayed in the advertisement area 301. In the settlement method selection area 351, buttons corresponding to each settlement method are displayed. In the present embodiment, the settlement methods include “cash”, “house card”, “credit card”, “prepaid card”, “transport A electronic money”, “transport B electronic money”, and “point”. Six types of settlement methods are used as examples. Hereinafter, “transportation A electronic money” and “transportation B electronic money” may be collectively referred to as electronic money. The electronic money can be charged in the POS terminal 20. Further, electronic money is used using a medium such as an IC card or a smartphone. In the present embodiment, an example in which an IC card is used as an example of a medium will be described.

  In the registered merchandise display area 302, the merchandise name, the score, and the total amount of the merchandise registered latest at the present time are displayed. In the example of FIG. 7A, it is displayed that the product name is red wine, the score is one, and the total price is 3000 yen. The total price display area 303 displays the points of the products registered up to the present and the total price. In the example of FIG. 7B, it is displayed that the score is 5 points and the total amount is 4270 yen. The display contents of the registered product display area 302 and the total price display area 303 are updated each time a product is registered.

  When the customer selects the transportation type A electronic money on the screen 1, a screen 2 shown in FIG. 7B is displayed. The screen 2 displays an advertisement area 301, a settlement method selection area 351, a registered product display area 302, and a total price display area 303. In the settlement method selection area 351, a button corresponding to the transportation A electronic money is displayed in a selected state to indicate that the transportation A electronic money has been selected. When the screen 2 is displayed for a predetermined time (for example, 500 milliseconds), the screen 2 switches to the screen 3 in FIG. The screen 3 displays an advertisement area 301, a guidance area 352, a registered product display area 302, and a total price display area 303. In the guide area 352, "Please touch the card" is displayed in order for the customer to read the IC card by the card settlement section 208.

  The POS terminal 20 obtains the balance of the IC card when the customer touches the IC card on the card settlement unit 208 or holds the IC card over the card settlement unit 208. The POS terminal 20 that has acquired the balance compares the balance with the total price of the commodities registered so far. As a result, when the balance is equal to or more than the total amount, it is possible to settle the commodity registered at the present time. On the other hand, if the balance is less than the total amount, settlement is impossible.

  Therefore, the POS terminal 20 performs different processing depending on whether payment is possible or not. First, when payment is possible, the POS terminal 20 displays the screen 4 of FIG. 8B. On the screen 4, an advertisement area 301, a guidance area 353, a registered product display area 302, and a total price display area 303 are displayed. In the guidance area 353, "Payment by transportation A electronic money", "Yes", "I do not need to charge, do you want to charge?", And the balance (5,000 yen in the figure) are displayed. .

  Of these buttons, “Yes” is a button for paying with transportation A electronic money without any charge. "No need to charge, do you want to charge?" Is a button for charging. In this way, when payment is possible, the customer can select a payment method before subtotaling. It is also possible to charge, and the balance is also displayed, so that the customer can charge when the balance is likely to be insufficient due to goods to be registered.

  On the other hand, when payment is not possible, the POS terminal 20 displays the screen 5 of FIG. The screen 5 displays an advertisement area 301, a guidance area 354, a registered product display area 302, and a total price display area 303. In the guidance area 354, "payment by transportation A electronic money", "stop", "insufficient balance. Do you want to charge?", Lack (2270 yen in the figure), and balance ( (2000 yen in the figure) is displayed. The customer presses "stop" to stop the settlement with the electronic money. When "quit" is pressed, screen 1 is displayed.

  On the other hand, when charging, the customer presses "Balance is insufficient. Do you want to charge?" In this way, if the balance is insufficient, it is possible to charge and the shortage is displayed, so that the customer can charge according to the goods and the balance to be registered from now on. As described above, in the present embodiment, when it is determined that the payment by the selected payment method is impossible, it is possible to cause the charging to be performed. As a result, since the charge can be performed before the declaration of the registration completion, the productivity of the product sales data processing device can be improved as compared with the case where the charge is performed after the declaration of the registration completion. In addition, it is possible to pay the shortage in cash without charging, but there are electronic money in which points are generated only by charging, and electronic money in which points are generated by paying in electronic money. For this reason, some customers want to charge and make a payment, but such a charging function meets the needs of the customers.

  If "No need to charge but charge?" Is pressed on screen 4, or if "Balance is insufficient. Do you want to charge?" Is displayed. FIG. 9B is a diagram showing a screen 6 which is an example of the charge screen. The screen 6 shows a charge screen displayed when “balance is insufficient. Do you want to charge?” Is pressed on the screen 5.

  On screen 6, "Please specify charge amount.", "1,000 yen", "2,000 yen", "3,000 yen", "5,000 yen", "10,000 yen" , "Cash remaining", "quit", shortage (2270 yen in the figure), and balance (2000 yen in the figure). Of these, “1,000 yen”, “2,000 yen”, “3,000 yen”, “5,000 yen”, and “10,000 yen” are charge amount buttons. The charge amount buttons corresponding to “1,000 yen” and “2,000 yen” are grayed out and cannot be pressed. This is because the shortage of the balance is not solved even if the charge of 1000 yen or 2000 yen is made. In this manner, the charge amount for which the balance shortage is not resolved is grayed out.

  “Remaining cash” is a button for paying the shortage in cash. In the case of the screen 6, 2270 yen is paid in cash. "Stop" is a button for stopping payment with electronic money. When "quit" is pressed, screen 1 is displayed.

  FIG. 10A is a diagram showing a screen 7 which is an example of a screen after charging. Screen 7 shows a screen displayed when 3000 yen is charged on screen 6. The screen 7 displays "Pay with the charged transportation A electronic money", "Yes", "No", and the balance (5000 yen in the figure). Among them, “Yes” is a button for paying with transportation A electronic money. "No" is a button for stopping payment with electronic money. When “No” is pressed, the screen 1 is displayed.

  In this way, if the balance is not insufficient after charging, the customer can select a settlement method before subtotaling. In addition, the customer can charge by pressing “No”, but can stop paying by electronic money.

  On the screen 1 shown in FIG. 7A, a settlement method other than electronic money can be selected. As an example, a screen when cash is selected as the settlement method will be described. FIG. 10B is a diagram illustrating a screen 8 displayed when “cash” is pressed on the screen 1 or when the change machine 209 detects insertion of a bill or coin. On the screen 8, an advertisement area 301, a settlement method selection area 351, a registered product display area 302, and a total price display area 303 are displayed. In the settlement method selection area 351, a button corresponding to cash is displayed in a selected state to indicate that cash is selected. As described above, in the present embodiment, when performing settlement with cash, the settlement method using cash can be selected by pressing “cash” on the screen 1 or by inserting bills or coins into the change machine 209.

  The processing for selecting the settlement method before the subtotal described above will be described with reference to a flowchart. In the present embodiment, since the selection of the settlement method and the registration of the product and the operation of the subtotal are performed in parallel before the subtotal, the processing related to the selection (FIGS. 11 to 15) and the processing of monitoring the registration and the subtotal (FIG. 16) The two processes will be described. In the registration and subtotal monitoring process, each time a product is registered, the total amount is compared with the balance, and the shortage flag indicating that the balance is insufficient and the subtotal flag indicating that the subtotal operation has been performed are updated. I do. Further, when the registration or the subtotal operation is performed, the processing for monitoring the registration and the subtotal is performed in preference to the processing related to the selection.

  First, processing related to selection will be described. In FIG. 11, when registration of a product is started, the POS terminal 20 displays a screen 1 (step S101). On the screen 1, the POS terminal 20 determines whether electronic money has been selected (step S102). If the electronic money has not been selected (step S102: NO), the POS terminal 20 proceeds to step S501 in FIG. When electronic money is selected (step S102: YES), the POS terminal 20 displays the screen 2 (step S103), and displays the screen 3 after 500 milliseconds (step S104).

  The POS terminal 20 acquires the balance of the IC card by the card settlement unit 208 (Step S105), and acquires the current total amount of the registered merchandise (Step S106). The acquired balance of the IC card can be referred to the registration and the process of monitoring the subtotal, which will be described later.

  The POS terminal 20 determines whether the balance is equal to or more than the total amount (Step S107). If the balance is less than the total amount (step S107: NO), the POS terminal 20 proceeds to step S211 in FIG. If the balance is equal to or greater than the total amount (step S107: YES), the POS terminal 20 displays the screen 4 (step S108), and proceeds to step S201 in FIG.

  The POS terminal 20 determines whether “Yes” is pressed on the screen 4 (Step S201). If “Yes” is pressed (step S201: YES), it is determined whether or not the subtotal flag is on (step S202). The subtotal flag is a flag that is updated in the process of registering and monitoring the subtotal as described above. When the subtotal flag is on, it indicates that the subtotal operation has been performed, and when the subtotal flag is off, the subtotal flag is off. , Indicates that the subtotal operation has not been performed.

  If the subtotal flag is on (step S202: YES), the POS terminal 20 determines the settlement method to be electronic money as it is because the subtotal operation has already been performed (step S203), and ends the process. On the other hand, if the subtotal flag is off (step S202: NO), the POS terminal 20 provisionally determines the settlement method to be electronic money (step S204).

  After the provisional determination, the POS terminal 20 determines that the balance is insufficient, and determines whether or not the shortage flag is on, because the product may be registered until the subtotal operation is performed (step S205). . The shortage flag is a flag that is updated in the process of registering and monitoring the subtotal as described above. When the subtotal flag is on, it indicates that the balance has become insufficient due to product registration, and the subtotal flag is turned off. In this case, it indicates that the balance is not insufficient.

  If the shortage flag is not on (step S205: NO), the POS terminal 20 determines whether the subtotal flag is on (step S206). If the subtotal flag is ON (step S206: YES), the POS terminal 20 proceeds to step S203. On the other hand, when the subtotal flag is off (step S206: NO), the POS terminal 20 performs step S205 again.

  If “Yes” is not pressed in step S201 (step S201: NO), “Charge is not necessary but charge?” (“Charge” in FIG. 12) is pressed on the screen 4. It is determined whether or not the operation has been performed (step S207). If "Charge is not required but charge?" Is not pressed (step S207: NO), the POS terminal 20 determines whether or not the shortage flag is on (step S208). Here, while the screen 4 is being displayed, it is determined whether or not the balance is insufficient due to the registration of the product. If the shortage flag is off (step S208: NO), the POS terminal 20 proceeds to step S201.

  If the shortage flag is on (step S208: YES), the POS terminal 20 turns off the shortage flag (step S209). This is not limited to step S208, and the shortage flag is referred to in other steps. Therefore, if the flag is not set to OFF, there is a possibility that the balance is determined to be insufficient even though the balance is not insufficient. Because there is.

  The POS terminal 20 pops up a balance shortage notification screen indicating that the balance is insufficient on the screen 4 (step S210), and displays the screen 5. The POS terminal 20 determines whether “quit” has been pressed on the screen 5 (step S212). If “quit” is pressed (step S212: YES), the POS terminal 20 returns to step S101 and displays the screen 1. If “quit” has not been pressed (step S212: NO), the POS terminal 20 proceeds to step S301 in FIG.

  In step S301 in FIG. 13, the POS terminal 20 determines whether or not “Insufficient balance. Do you want to charge?” (“Charge” in FIG. 13) on the screen 5 (FIG. 13). Step S301). If "balance is insufficient. Do you want to charge?" Is not pressed (step S301: NO), the POS terminal 20 determines whether or not the shortage flag is on (step S302). Here, while the screen 5 is being displayed, it is determined whether or not the balance is insufficient due to the registration of the product. If the shortage flag is off (step S302: NO), the POS terminal 20 proceeds to step S212 in FIG. If the shortage flag is on (step S302: YES), the POS terminal 20 proceeds to step S209 in FIG.

  On the other hand, if “balance is insufficient. Do you want to charge?” Is pressed (step S301: YES), the POS terminal 20 displays the screen 6 (step S303). The POS terminal 20 determines whether or not the charge amount is specified on the screen 6 (Step S304). If the charge amount has been designated (step S304: YES), the POS terminal 20 performs a deposit process with the change machine 209 (step S305), and adds the deposit amount to the balance of the IC card (step S306). Thereby, charging is performed. In step S306, in order to update the balance acquired in step S105, it is possible to refer to the balance of the IC card in the process of monitoring the registration and the subtotal described below.

  Next, the POS terminal 20 turns off the shortage flag (step S307). In the process of turning off the balance, the balance is insufficient due to registration of the product during the payment process and the balance is updated by the payment process even if the shortage flag is turned on. It is processing for.

  The POS terminal 20 determines whether the balance is equal to or greater than the total amount (Step S308). If the balance is less than the total amount (step S308: NO), the POS terminal 20 pops up a balance shortage notification screen (step S309), and displays the screen 6 again in step S303. On the other hand, if the balance is equal to or greater than the total amount (step S308: YES), the POS terminal 20 displays the screen 7 (step S310), and proceeds to step S401 in FIG.

  If the charge amount has not been specified in step S304 (step S304: NO), the POS terminal 20 determines whether or not “quit” has been pressed on the screen 6 (step S311). If "quit" is pressed (step S311: YES), the POS terminal 20 returns to step S101 and displays the screen 1. If “quit” has not been pressed (step S311: NO), the POS terminal 20 determines whether or not “cash remaining” has been pressed on the screen 6 (step S312).

  If “cash is remaining” is pressed (step S312: YES), the POS terminal 20 determines whether the subtotal flag is on (step S313). If the subtotal flag is on (step S313: YES), the POS terminal 20 determines the settlement method to be electronic money and cash as it is because the subtotal operation has already been performed (step S314), and ends the processing. . On the other hand, when the subtotal flag is off (step S313: NO), the POS terminal 20 tentatively determines the settlement method to be electronic money and cash (step S315). After the provisional determination, the POS terminal 20 determines whether or not the subtotal flag is on (step S316). If the subtotal flag is on (step S316: YES), the POS terminal 20 proceeds to step S314. On the other hand, when the subtotal flag is off (step S316: NO), the POS terminal 20 performs step S316 again.

  When “cash is remaining” is not pressed (step S312: NO), the POS terminal 20 determines whether or not the shortage flag is on (step S317). Here, while the screen 6 is being displayed, it is determined whether or not the balance is insufficient due to the registration of the product. If the shortage flag is off (step S317: NO), the POS terminal 20 proceeds to step S304. If the shortage flag is on (step S317: YES), the POS terminal 20 turns off the shortage flag (step S318), pops up a balance shortage notification screen (step S319), and returns to the screen 6 in step S302. Is displayed.

  7, the POS terminal 20 determines whether “Yes” is pressed on the screen 7 (step S401). If "Yes" is pressed (step S401: YES), it is determined whether or not the subtotal flag is on (step S402). If the subtotal flag is ON (step S402: YES), the POS terminal 20 determines the settlement method to be electronic money as it is because the subtotal operation has already been performed (step S403), and ends the process. On the other hand, if the subtotal flag is off (step S402: NO), the POS terminal 20 provisionally determines the settlement method to be electronic money (step S404).

  After the tentative determination, the POS terminal 20 determines whether the shortage flag is on (step S405). If the shortage flag is not on (step S405: NO), the POS terminal 20 determines whether the subtotal flag is on (step S406). If the subtotal flag is on (step S406: YES), the POS terminal 20 proceeds to step S403. On the other hand, when the subtotal flag is off (step S406: NO), the POS terminal 20 performs step S405 again. If the shortage flag is on in step S405 (step S405: YES), the POS terminal 20 proceeds to step S209.

  In step S401, if “Yes” is not pressed (step S401: NO), it is determined whether “No” is pressed (step S407). If “No” is pressed (step S407: YES), the POS terminal 20 returns to step S101 and displays the screen 1. If “NO” has not been pressed (step S407: NO), the POS terminal 20 determines whether or not the shortage flag is ON (step S408). If the shortage flag is not on (step S408: NO), the POS terminal 20 returns to step S401. If the shortage flag is on (step S408: YES), the POS terminal 20 proceeds to step S209.

  The following flowchart of FIG. 15 shows processing when a payment method other than electronic money is selected (NO in step S102 of FIG. 11). In FIG. 15, the POS terminal 20 determines whether a credit card or a house card has been selected (step S501). If a credit card or a house card is selected (step S502: YES), the POS terminal 20 checks the validity of the selected card from the credit card or the house card (step S502). When the card selected from the credit card or the house card is valid (step S503: YES), the POS terminal 20 determines the payment method to the selected card from the credit card or the house card ( Step S505), the process ends. On the other hand, when the selected card of the credit card or the house card is not valid (step S503: NO), the POS terminal 20 pops up an invalidation notification screen indicating that the selected card is invalid. Then (step S504), the process returns to step S101.

  If a credit card and a house card have not been selected (step S502: NO), the POS terminal 20 determines whether cash has been selected on the screen 1 or whether a change has been detected by the change machine 209 (step S502). S506). If cash is selected on the screen 1 or payment is detected by the change machine 209 (step S506: YES), the POS terminal 20 determines cash as the settlement method (step S507), and ends the processing.

  When cash is not selected on the screen 1 and no payment is detected by the change machine 209 (step S506: NO), the POS terminal 20 determines whether a prepaid card is selected on the screen 1 (step S506). Step S508). If the prepaid card is selected on the screen 1 (step S508: YES), the POS terminal 20 determines the payment method as the prepaid card (step S509), and ends the processing.

  If the prepaid card has not been selected on the screen 1 (step S508: NO), the POS terminal 20 determines whether a point has been selected on the screen 1 (step S510). If a point is selected on the screen 1 (step S510: YES), the POS terminal 20 determines the payment method as a point (step S509), and ends the processing. If no point is selected on the screen 1 (step S510: NO), the POS terminal 20 returns to step S101.

  As shown in FIG. 15 described above, the determination content differs depending on the selected settlement method. For example, in the case of a credit card, validity is checked unlike electronic money. Thereby, it is possible to cope with various settlement methods having different judgment contents.

  Next, processing for monitoring registration and subtotals when electronic money is selected will be described. FIG. 16 is a flowchart showing processing for monitoring registration and subtotals. In FIG. 16, the POS terminal 20 determines whether or not a product has been registered (step S601). If the product has been registered (step S601: YES), the POS terminal 20 acquires the current total amount (step S602) and acquires the balance of the IC card (step S603). The balance acquired here is the balance acquired in step S105 or the balance updated in step S305.

  The POS terminal 20 determines whether the balance is equal to or more than the total amount (Step S604). If the balance is less than the total amount (step S604: NO), the POS terminal 20 turns on the shortage flag (step S605), and returns to step S601. If the balance is equal to or greater than the total amount (step S604: YES), the POS terminal 20 returns to step S601. If the product is not registered in step S601 (step S601: NO), the POS terminal 20 determines whether or not a subtotal operation has been performed (step S606). If the subtotal operation has been performed (step S606: YES), the POS terminal 20 turns on the subtotal flag (step S607) and ends the process. If the subtotal operation has not been performed (step S606: NO), the POS terminal 20 returns to step S601.

  As described above, according to the present embodiment, it is possible to determine whether or not settlement by the selected settlement method is possible before the completion of registration of a product is declared. As a result, the customer can know whether or not payment is possible before the completion of registration of the product is declared, so that the customer can consider the settlement method to be selected. In comparison, the productivity of the product sales data processing device can be improved.

  Further, according to the present embodiment, since the customer can select the settlement method during the registration, the clerk can quickly perform the work of the clerk, for example, the clerk can immediately perform the settlement process after the registration of the product.

  Further, according to the present embodiment, the balance of electronic money can be confirmed before pressing the subtotal key, and if the balance is insufficient, it is possible to switch to charging or another settlement method. If the balance is not insufficient, the settlement method can be specified as it is. Note that the prepaid card is also a prepaid medium, and some of the prepaid card can be charged. Therefore, the processing shown in FIGS. 11 to 16 (such as balance inquiry and charge) can be applied similarly to the electronic money. In addition, some prepaid cards can be charged in units of one yen, so that the amount desired by the customer may be charged. Further, since it is possible to charge only the shortage, the customer puts a predetermined amount (for example, the total amount of money in possession or an amount larger than the estimated necessary amount) into the change machine 209, and the amount larger than the total amount is paid. You may make a refund.

  In the present embodiment, the shortage of the balance is notified by displaying it on the customer side display unit 205. However, the shortage of the balance may be displayed on the clerk side display unit 210 to notify the clerk. In particular, in a merchandise sales data processing apparatus in which the customer side display unit 205 is not provided, the fact that the balance is insufficient may be displayed on the clerk side to inform the clerk.

  In the embodiment described above, the settlement method using one IC card for electronic money has been described. However, depending on the type of electronic money, a plurality of IC cards can be used. A screen display example of the customer-side display unit 205 when using a plurality of IC cards will be described. FIG. 17A shows a screen 9 displayed when the balance of the first IC card is insufficient. On the screen 9, an advertisement area 301, a guidance area 357, a registered product display area 302, and a total price display area 303 are displayed.

  In the guidance area 357, "Payment by electronic money for transportation A", "Stop", "Check the balance of another card", "Insufficient balance. Do you want to charge?" In the figure, 2270 yen) and the balance (2000 yen in the figure) are displayed. The customer presses "stop" to stop the settlement with the electronic money. When "quit" is pressed, screen 1 is displayed. When charging, the customer presses "Balance is insufficient. Do you want to charge?" When the customer inquires the balance with another IC card, the customer presses "inquire another balance". When "Inquire another balance" is pressed, the screen 10 of FIG. 17B is displayed.

  On the screen 10, guidance areas 358 and 359, a registered product display area 302, and a total price display area 303 are displayed. In the guidance area 358, "Please touch the card of the transportation A electronic money" is displayed in order to make the customer read the IC card by the card settlement section 208. In the guidance area 359, a total display area 360, "Stop", "Pay the balance by another method", shortage (2270 yen in the figure), and balance (2000 yen in the figure) are displayed. In the total display area 360, the balance of the first IC card (2000 yen in the figure), “Please touch” for urging the user to touch the second IC card, and the total balance (2000 yen in the figure) ) Is displayed. When the IC card is read by the card settlement unit 208, the screen 11 of FIG. 18A is displayed.

  On the screen 11, guidance areas 358 and 361, a registered product display area 302, and a total price display area 303 are displayed. In the guide area 361, the total display area 360, the "end of charge", and the balance after payment (630 yen in the figure) are displayed. The total display area 360 displays the balance of the first IC card (2000 yen in the figure), the balance of the second IC card (3000 yen in the figure), and the total balance (5000 yen in the figure). Is done. When the customer presses "end of charge", the settlement method is provisionally determined to be electronic money.

  The screen 12 in FIG. 18B shows an example of a screen in the case of performing settlement using a plurality of IC cards. On the screen 12, a guidance area 362, a registered product display area 302, and a total price display area 303 are displayed. In the guidance area 362, "Please touch the card of transportation A electronic money" is displayed in order to make the customer read the IC card by the card settlement unit 208. In the guide area 362, the customer is displayed which IC card should be read, such as "first card". By doing so, even when making a payment with a plurality of IC cards, the customer can read the IC cards without confusion. Actually, the order of the IC cards whose balances are referred to may be different from the order of reading at the time of settlement. In addition, as long as payment can be made so as to satisfy the total amount, payment may be made using an IC card different from the IC card whose balance is referred to.

  Regardless of whether one or a plurality of IC cards are used, if the customer accidentally reads another IC card of the same type, the customer will settle the payment as it is if the total amount can be satisfied. You may be informed that "Payment was made with another IC card" or you may be informed "Would you like to pay with another IC card?" The customer and the sales clerk are notified that the balance is insufficient.

  FIG. 19 is a diagram showing a screen 13 displayed when “pay the remaining money by another method” is pressed on the screen 10. The screen 13 displays a guidance area 363, a settlement method selection area 351, a registered product display area 302, and a total price display area 303. In the guide area 363, the payment amount of electronic money (2000 yen in the figure) and the balance (2270 yen in the figure) are displayed, and the customer is prompted to select a payment method. By selecting the payment method displayed in the payment method selection area 351, the customer can perform payment using both electronic money and another payment method. As described above, in the present embodiment, when it is determined that settlement by the selected settlement method is impossible, a settlement method other than the selected settlement method can be selected. Thereby, since the settlement method can be selected before the declaration of the registration completion, the productivity of the commodity sales data processing device can be improved as compared with the case where the settlement method is selected after the declaration of the registration completion.

  In the embodiment described above, types of payment methods that can be selected may be limited before registration completion is declared. As a result, payment methods such as credit cards that cannot be charged will not be displayed before registration completion is declared, but will be displayed after registration completion is declared, and payment methods that can be charged will be displayed. By restricting the payment method displayed before the registration completion is declared, such as displaying before the registration completion is declared, the customer can efficiently select the payment method.

  In addition, although the customer selects the settlement method on the customer side display unit 205, the present invention is not limited to this, and the clerk may select the settlement method on the clerk side display unit 210. At this time, the payment method selectable by the customer may be within the range of the payment method selectable by the clerk. This limits the selectable range so that the customer cannot select the type of payment method (gift certificate, etc.) that is better to be selected by the clerk or that must be operated by the clerk. Erroneous operation and fraud can be prevented.

  In the embodiment described above, the embodiment uses one POS terminal 20, but the embodiment may be applied to a system including a plurality of devices. For example, the present invention may be applied to an apparatus operated by a clerk and an apparatus operated by a customer different from each other.

  In addition, a gift certificate, a discount ticket, and the like may be input before registration completion is declared. Even in this case, since it is possible to confirm whether or not the gift certificate is usable before the completion of registration is declared, the productivity of the commodity sales data processing device can be improved.

  Alternatively, the fact that the customer has selected the settlement method may be displayed on the clerk side display unit 210 to notify the clerk. As a notification method, an area for displaying the selected settlement method on the clerk-side display section 210 or displaying the display content of the customer-side display section 205 is provided, and the display content of the customer-side display section 205 is displayed in the area. May be. Whether or not to display the display content of the customer-side display unit 205 on the clerk-side display unit 210 may be switched between display and non-display depending on the setting of the clerk.

  The advertisement area 301 provided on the screen described above may be used as a settlement method selection area. For example, an area obtained by combining the advertisement area 301 and the settlement method selection area 351 may be set as the settlement method selection area. As a result, the settlement method can be displayed in a larger size, so that the customer can easily select the settlement method.

  In the above-described screen 5 or the like, the payment method is selected once, for example, when “stop” is pressed, but as a result, in the screen for selecting the payment method when registration completion is declared without selecting the payment method. The button corresponding to the payment method once selected may be different from the display mode of the other buttons. This makes it easier for the customer to recognize the payment method once selected, and also makes it easy to identify other payment methods. Since it is possible to easily recognize the payment method, it is possible to easily select the payment method even when the customer thinks that "let's settle with the payment method selected first".

  The POS terminal 20 in the present embodiment is provided with the change machine 209 on the customer side, and can be charged without the intervention of a clerk. That is, charging can be performed without interrupting the operation of the clerk. In particular, in convenience stores, since there are clerk-mediated products (products prepared by clerks such as cigarettes and hot snacks), a function that can be charged without the intervention of clerks is very effective. With such a configuration, charging can be performed in parallel with registration, so that the productivity of the merchandise sales data processing device can be further improved.

  Alternatively, after the customer first puts cash into the change machine 209 in order to pay with cash, it may be possible to charge electronic money without paying with the put cash. Thus, the settlement method may be changeable. For example, it is possible to cope with a case where a customer intends to obtain coins by change and settles in cash, but still changes his mind to charge. Thus, it is possible to flexibly cope with a case where the customer changes the settlement method.

  Some electronic money has an auto charge function. The auto charge function is a function for automatically charging the second set amount when using electronic money when the balance becomes equal to or less than the first set amount. In the case of an IC card having an auto charge function, the charge may be guided when it is determined that the balance after payment is less than the first set amount.

  Further, as described with reference to the screen 7, in the present embodiment, it is possible to perform only charging. Accordingly, the customer can charge the electronic money for settlement during the registration of the product, and can also charge only the other electronic money, which greatly enhances the convenience. When electronic money that cannot be charged is read by the POS terminal 20, a notification indicating that charging is not possible (for example, "cannot be charged. Please settle the remaining balance using another payment method") is performed. You may.

  In the embodiment described above, the POS terminal 20 has been described as an example of the product sales data processing device, but any product sales data processing device that can use electronic money may be used. For example, the present invention can also be applied to a semi-self-type product sales data processing system in which a registration device for registering a product and an accounting device for performing settlement of a price are configured by different devices. Specifically, the registration device selects the settlement method by allowing the customer to check and charge the balance of the electronic money during the registration of the product, and transmits the selected settlement method to the accounting device. Even with such a configuration, the customer can know whether payment is possible or not before the completion of registration of the product is declared. Productivity can be improved.

  In the embodiment described above, the purchase transaction and the charge of the product may be treated as one transaction or may be treated as different transactions. When treating a purchase transaction and a charge of a product as one transaction, the contents of each transaction may be output together as one receipt. In this case, only one transaction number is uniquely given for each transaction, and the transaction number is also recorded as one transaction in the journal.

  On the other hand, in the case where the purchase transaction of the product and the charge are treated as different transactions, a receipt indicating the content of the purchase transaction of the product and a receipt indicating the content of the charge may be separately output. In this case, a transaction number and a transaction number are given to the purchase transaction and the charge of the product, respectively, and are recorded as different transactions in the journal. Further, when the product is charged during the registration of the product, a receipt indicating the content of the charge may be output at that time. That is, the output may be performed irrespective of the output timing of the receipt indicating the content of the purchase transaction of the product.

  In the above-described embodiment, the completion of the registration of the product is the pressing of the subtotal key by the clerk, but is not limited to this. For example, in the case of registering a product by imaging the product and recognizing the captured product by image recognition, the recognition of all the products to be purchased ends, and the subtotal key (or the key for selecting a settlement method) is pressed. When the registration is completed. In addition, if the electronic tag is attached to the product in advance, the registration of the product is performed by reading the electronic tag, so the registration is completed when the reading of the electronic tag attached to all the products to be purchased is completed. Completed. Thus, the completion of the registration of the product is not limited to a human operation such as pressing a subtotal key. Further, according to the present embodiment, even when the electronic tag is read or the product is recognized and registered by imaging, if the customer selects a payment method, whether or not payment by the selected payment method is possible. The determination can be made before the registration completion of the product is declared.

  Here, a designation method in the above-described semi-self mode will be described. In the semi-self mode, it is necessary to designate a POS terminal operating in the accounting mode from a POS terminal operating in the registration mode. In the following description, a POS terminal operating in the registration mode is referred to as a registration device, and a POS terminal operating in the checkout mode is referred to as a checkout device.

  As a mode for designating an accounting device for executing an accounting process from among a plurality of accounting devices, an accounting device for executing an accounting process is designated by a clerk using a registration device (first designation mode), There is a mode (second designation mode) in which a customer issues a handed-out bill from a registration apparatus and a customer reads the bill passed out from a clerk on one billing apparatus. The embodiment is not limited to the above embodiment. For example, a mode in which an accounting device is specified as follows may be used.

  As one aspect, in response to an operation performed on a send button displayed in response to the completion of the product registration (or an operation that declares the completion of the product registration may be performed), the registration device For example, an accounting device is inquired of a status to recognize an accounting device capable of performing accounting (for example, no failure has occurred and is not in use), and a predetermined rule (for example, accounting) is selected from accounting devices that are not in use. One accounting device is determined according to the device number order). Then, the registration device transmits the accounting information to the determined accounting device and instructs execution of the accounting process.

  As another aspect, the priority of the accounting process is set in advance for the accounting device. Then, in response to the completion of the merchandise registration, the display is made so that the operation of the transmission button for instructing the transmission of the accounting information to the accounting device becomes valid. In response to the operation of the send button, the registration device checks whether or not the accounting device can perform the accounting process in the order according to the set priority, and confirms that the accounting process is possible. If not, make sure the priorities check for the next accounting device. Then, the registration device transmits the accounting information to the accounting device that is first confirmed that the accounting process is possible, and instructs execution of the accounting process.

  In another aspect, the enrollment device sends accounting information to all accounting devices. When the accounting device that has received the accounting information becomes able to execute the accounting process using the accounting information included in the accounting information received by the accounting device, the accounting device issues an accounting process execution notification notifying that the accounting device performs the accounting process. The accounting information is transmitted to the registration device.

  The registration device performs display (accounting process execution display) indicating the accounting device to which the accounting process execution notification is transmitted in response to receiving the accounting process execution notification. The clerk sees the accounting process execution display, and tells the customer which accounting device performs the accounting process.

  At this time, together with the display of the accounting process execution, the signing pole of the accounting device that has transmitted the accounting process execution notification is lit in a predetermined pattern, or the accounting device outputs a predetermined notification sound, thereby allowing the accounting device to execute the accounting process. The execution may be notified.

  As another aspect, a store clerk moves a shopping cart containing a product for which product registration has been completed by the registration device to one of the basket storage places corresponding to each accounting device. .

  The basket storage is provided with a sensor for detecting the placed shopping basket. When it is determined by the sensor that the shopping basket is placed, the corresponding accounting device makes a request, acquires the corresponding accounting information from the registration device, and executes the accounting process. Also in this case, the accounting device that has executed the accounting process may notify that the accounting device is to execute the accounting process by turning on a sign pole or outputting a notification sound.

  As another aspect, the registration device transmits, to a certain accounting device, accounting instruction information including accounting information and transfer order information in which a transfer order between a plurality of accounting devices is set. The transfer order information may specify the transfer order cyclically between the accounting devices.

  The accounting device that has received the accounting instruction information transmits an accounting processing execution notification to the registration device that has transmitted the accounting instruction information, if the accounting device can execute the accounting process, and includes the accounting instruction information in the received accounting instruction information. Execute accounting processing using the accounting information.

  On the other hand, if the accounting device that has received the accounting instruction information cannot execute the accounting process, the accounting device receives the accounting instruction information, and the transfer order is received for the next accounting device according to the transfer order information included in the received accounting instruction information. Transfer the accounting instruction information. In this way, by sequentially transferring the accounting instruction information between the accounting devices, a procedure corresponding to designation of the accounting device to be executed the accounting process is realized.

  Note that a program for implementing the POS terminal 20 described above may be recorded on a computer-readable recording medium, and the program may be read and executed by a computer system. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” refers to a portable medium such as a flexible disk, a magneto-optical disk, a ROM, and a CD-ROM, and a storage device such as a hard disk built in a computer system.
