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

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

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

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

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

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

The clerk-side display unit 210 is a touch display for the clerk, displays various information to the clerk, and receives various inputs from the clerk.

Good. When a preset key corresponding to a product is displayed on the clerk side display unit 210, the clerk may operate the preset key to register the product.

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

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

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

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

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

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

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

(Product registration (clerk side))
“Product registration (clerk side)” is a function of registering a purchased product on the clerk side (clerk side scanner section 212, clerk side display section 210, key operation section 211). In other words, this function is to execute a process of registering a purchased product by a clerk's operation (scan by the clerk-side scanner unit 212, touch on the clerk-side display unit 210, operation of the key operation unit 211).

(Product registration (customer side))
“Product registration (customer side)” is a function of registering a purchased product on the customer side (customer side scanner unit 206, customer side display unit 205). In other words, the function of executing the registration process of the purchased product by the operation of the customer (scanning by the customer side scanner unit 206, touching the customer side display unit 205).

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

(Send registration information to other terminals)
The “transmission of registration information to another terminal” is to transmit the registration information generated in the registration process to another terminal (another terminal capable of executing a settlement process; for example, another POS terminal 20) (directly to another terminal). This is a function of transmitting or indirectly transmitting to another terminal via the store controller 10 or the monitoring terminal.

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

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

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

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

(Normal mode (standard mode))
As shown in FIG. 5A, the normal mode (standard mode) is an operation mode in which merchandise registration (clerk side) is set to valid “有効” and merchandise registration (customer side) is set to invalid “−”. That is, the normal mode (standard mode) is an operation mode in which the clerk does not perform the registration process on the customer side but performs the registration process.

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

  As shown in FIG. 5A, the normal mode (standard mode) is an operation mode in which both the reception of registration information from another terminal and the reading of a bill are valid “有効”. That is, in the normal mode (standard mode), the settlement process can be executed based on the registration information generated in the other terminal. Note that the settlement process after receiving the registration information (or after reading the bill) may be executed as the semi-self mode in FIG. That is, when the registration information is received (or the bill is read) in the normal mode (standard mode), the normal mode (standard mode) is automatically changed to the semi-self mode (accounting-only mode) (clerk). May be requested), and the settlement process may be executed in the semi-self mode (accounting-only mode). In addition, when the settlement process is executed after shifting to the semi-self mode (accounting-only mode), the mode automatically changes from the semi-self mode (accounting-only mode) to the normal mode (standard mode) (a permission from a clerk may be requested). It may be shifted (returned) or may remain in the semi-self mode (accounting-only mode).

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

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

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

  In the full self mode, as shown in FIG. 5 (A), an operation mode in which the insertion of money is valid “〇”, and the transmission of registration information to another terminal and the issuance of a banknote are invalid “−”. It is. That is, the full self mode is an operation mode on the premise of the settlement process in the terminal.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

(Transition of operation mode by mode switching operation)
Subsequently, the transition of the operation mode by the mode switching operation will be described. The operation mode of the POS terminal 20 is switched according to an explicit mode switching operation by a clerk (see FIG. 6). Specifically, the operation mode is switched according to the operation of the mode switching button 211a (see FIG. 3B) arranged at the uppermost stage and the rightmost end of the key operation unit 211.

  In addition, since the mode switching button 211a is arranged at the corner of the key operation unit 211, it is possible to reduce operation mistakes when switching the operation mode and to easily switch the operation mode. In other words, when the mode switching button 211a is present at the corner of the key operation unit 211, for example, compared to when the mode switching button 211a is located near the center of the key operation unit 211, for example, the mode switching button 211a to be operated is Since the number of adjacent other buttons is small, operation errors such as operating other buttons in a hurry are unlikely to occur. In addition, since the position of the mode switching button 211a to be operated can be instantaneously specified, the mode switching operation can be performed without stress. It can be performed.

  Furthermore, since the mode switching button 211a is arranged at the upper right corner (uppermost and rightmost) of the key operation unit 211, the mode switching operation is performed not only when the clerk is at the clerk but also when at the customer. Will be able to do it. In other words, the clerk at the customer side cannot usually visually recognize each button of the key operation unit 211, but the mode switching button 211a at the upper right end of the key operation unit 211 reaches out from the customer side, Since the mode switching button 211a to be operated can be easily recognized only by (feeling of the hand), the clerk at the customer side can perform the mode switching operation without moving to the clerk side.

  In the present embodiment, the mode switching button 211a is arranged at the upper right corner of the key operation unit 211. However, if the mode can be recognized only by groping (a position that can be recognized relatively easily), the mode switching button 211a The switching button 211a may be arranged at a position other than the upper right corner of the key operation unit 211. Also, instead of or in addition to arranging the mode switching button 211a at a position that can be recognized only by groping (for example, a corner at the upper right end), it can be distinguished from other buttons even from the customer side. A mode switching button 211a may be formed on the printer. For example, the size of the mode switching button 211a may be made different from the sizes of the other buttons, or the shape of the mode switching button 211a may be made different from the shapes of the other buttons to the extent that it can be distinguished only by groping. Or the height of the mode switching button 211a may be different from the height of the other buttons (for example, the mode switching button 211a may be protruded from the other buttons). ), The feel of all or a part of the surface (the surface to be touched) of the mode switching button 211a may be made different from the feeling of the other buttons (for example, only the surface of the mode switching button 211a is rough or bumpy). The touch may be provided, or a protrusion or a depression may be provided only on the surface of the mode switching button 211a.)

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

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

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

  When the registration process by the clerk is completed, the customer checks the total price of the purchased merchandise on the clerk-side display unit 210, inserts money (cash) into the change machine 209, or operates the card settlement unit 208 to make a payment. (Lower part of FIG. 7). That is, the POS terminal 20 executes the settlement process by a customer operation or the like (input of cash into the change machine 209, operation of the card settlement unit 208) (the lower part of FIG. 7).

  That is, when the settlement process is executed in the own terminal in the normal mode, as shown in FIG. 8, first, the clerk scans the product on the clerk side (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. The subtotal key in step S30 is an operation key for completing the registration process, and may be referred to as a subtotal button, a registration completion key, a registration completion button, a checkout key, a checkout button, or the like.

  The customer may wait until the clerk completes the registration process (until the total amount is determined), or may put cash into the change machine 209 before the registration process is completed. That is, the POS terminal 20 can accept payment during the registration process (upper row in FIG. 7).

  Further, the customer may select a payment method (also referred to as a payment type, a payment method, or a payment type) before the registration processing is completed. That is, the POS terminal 20 can accept the selection of the payment method during the registration process.

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

  In addition, when there is change, the POS terminal 20 controls the dispensing of change and bills by the change machine 209 to prevent forgetting to take the change, and a sensor or the like detects that the customer has removed the change or bill. , The receipt of the receipt by the printing unit 213 may be controlled. The same applies to other operation modes.

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

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

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

  The information required for the settlement process (such as registration information generated in the POS terminal 20-1) is supplied to the other POS terminal 20 (POS terminal 20-2).

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

  That is, when the other terminal performs the settlement process in the normal mode, as shown in FIG. 10A, the clerk first scans the product (step S10: YES) and registers the product (step S11). ). After pressing a subtotal key (for example, a subtotal key displayed on the clerk-side display unit 210 or a subtotal key arranged on the key operation unit 211) (step S30: YES), for example, the settlement process is executed. Is specified (step S31: YES), the registration information is transmitted to the specified POS terminal 20 (step S32), and the processing on the registration side is completed.

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

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

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

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

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

  As described above, the normal mode (standard mode) is a function in which the clerk executes the registration process and then executes the payment process on the customer side of the terminal using the registration information generated in the registration process (FIG. 7). , FIG. 8), and a function of transmitting the registration information generated in the registration process to another terminal (another terminal capable of executing a settlement process; for example, another POS terminal 20) to cause the other terminal to execute the settlement process. (See FIG. 9 and FIG. 10) and issue a bill of coupon printed by converting the registration information generated in the registration process (or information for acquiring the registration information) into a code (a bar code, a two-dimensional code, etc.). And causing the other terminal to execute a settlement process.

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

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

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

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

  In the full self mode, the customer registers his or her purchased merchandise on the customer side (customer-side scanner unit 206, customer-side display unit 205) (upper row in FIG. 11). That is, the POS terminal 20 executes the registration processing of the purchased product by the operation of the customer (scan by the customer-side scanner unit 206, touching the customer-side display unit 205) (the upper part of FIG. 11).

  When the registration process is completed, the customer confirms the total price of the purchased merchandise on the customer side display unit 205 and puts cash into the change machine 209 or operates the card settlement unit 208 to make a payment (lower part in FIG. 11). ). That is, the POS terminal 20 executes the settlement process by a customer operation or the like (input of cash into the change machine 209, operation of the card settlement unit 208) (the lower part of FIG. 11).

  That is, in the case of the full self mode, as shown in FIG. 12, the customer scans the product on the customer side (step S20: YES) and registers the product (step S21). After the registration completion key (for example, the registration completion key displayed on the customer side display unit 205) is pressed (step S40: YES), the customer's side performs settlement by, for example, the change machine 209 (step S50). Is completed. The registration completion key according to step S40 is an operation key for completing the registration process, and may be referred to as a registration completion button, a subtotal key, a subtotal button, a checkout key, a checkout button, or the like.

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

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

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

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

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

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

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

  In the double scan mode, the clerk may wait until the customer completes the payment (until the customer takes a change or 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. 13). Further, the clerk may be absent during the checkout by the customer (lower part in FIG. 13). That is, during the checkout of the customer, the reception of the customer may be ended.

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

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

  Further, each POS terminal 20 may report the current operation mode of another terminal instead of or in addition to the current operation mode of the own terminal. That is, the POS terminals 20 may notify each other of the current operation mode of the other terminal by recognizing the current operation mode of the other terminal. One example of a method in which each POS terminal 20 recognizes the current operation mode of another terminal is that each POS terminal 20 notifies another terminal of the operation mode after the transition (the latest operation mode) after the transition of the operation mode (the LAN 11). Via the store controller 10 or the monitoring terminal). Further, each POS terminal 20 may report the current processing status of the other terminal as well as the current operation mode of the other terminal.

  Further, each POS terminal 20 may report information according to the current operation mode or the like (operation mode, processing status, or the like) of the own terminal. For example, when the current operation mode of the POS terminal 20 is the full self mode, for example, each of the POS terminals 20 may display various types of information on the customer-side display unit 205 during standby. Further, the POS terminal 20 may notify information according to the current operation mode of another terminal instead of or in addition to the information according to the current operation mode of the own terminal.

  Even when the operation mode is switched by the operation of the clerk (by the mode switching operation, the reading of the clerk code, etc.), the operation mode is switched without the operation of the clerk (mode switching instruction, predetermined time). However, the operation mode of the own terminal or another terminal is notified.

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

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

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

In the above example, the POS terminal 20-2 that has executed the settlement process stores information indicating that the registration process has been executed in the other terminal (POS terminal 20-1) as information related to the transaction, and stores it in its own terminal (POS terminal). Information indicating that the settlement process has been executed in the terminal 20-2) may be stored.
More specifically, the POS terminal 20-2 stores the terminal identification information of the other terminal (POS terminal 20-1) as the information (terminal identification information) of the terminal that has performed the registration process, and the terminal that has performed the settlement process. The terminal identification information of the own terminal (POS terminal 20-2) may be stored as the terminal identification information. In the above example, the terminal identification information and the operation mode (specifically, the normal mode (standard mode)) of the POS terminal 20-1 that has performed the registration processing are set on the side of the POS terminal 20-2 that executes the payment processing. What is necessary is that information to identify can be obtained. For example, the terminal identification information of the POS terminal 20-1 and the information for identifying the operation mode are supplied from the POS terminal 20-1 to the POS terminal 20-2 (for example, transmission and reception as registration information, Supplied through an external power supply).

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

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

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

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

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

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

  FIG. 15A shows the display contents of the registration start screen before the start of the registration processing. In FIG. 15A, a registration start button BT30 on the right side of the screen is a button for instructing the start of product registration. The customer operates the registration start button BT30 when starting product registration. Buttons BT35 to BT37 at the lower left of the screen are buttons for switching the display language to English, Chinese, and Korean, respectively.

  FIG. 15B shows the display contents of the registration screen in a state where two items of goods (daifuku mochi) are registered. When the registration start button BT30 is operated on the registration start screen shown in FIG. 15A, the POS terminal 20-3 displays a registration screen in which no product is registered yet. FIG. 15B shows a registration screen after a product (tea, Daifuku mochi) has already been registered for convenience.

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

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

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

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

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

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

  FIG. 16E shows the display contents of a payment screen (receipt screen) displayed when the change is removed. For example, when the change is removed from the outlet of the change machine 209, the POS terminal 20-3 displays a receipt screen as shown in FIG. The POS terminal 20 may be provided with a sensor such as a photo sensor in the vicinity of the take-out opening, and when the sensor recognizes an object (assuming a customer's hand), it may be determined that the change has been removed. FIG. 16F shows an example of the standby screen. An advertisement (product advertisement, event advertisement, etc.) may be displayed on the standby screen.

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

  Next, according to the state of the change machine 209, the process of prohibiting the execution of the settlement process and transmitting (outputting) transaction-related information (registration data) relating to the transaction to another device (hereinafter, also referred to as “change machine failure handling process”). Will be described. 17, 18, and 19 are diagrams illustrating screen examples displayed on the clerk-side display unit 210 and the customer-side display unit 205 of the POS terminal 20 operating in the normal mode (standard mode).

  FIG. 17A is a diagram illustrating a registration screen displayed on the clerk-side display unit 210 in a normal state in which a failure has not occurred in the change machine 209. Here, as obstacles of the change machine 209, near full (a state in which a certain currency type stored in the change bill machine is almost full), near end (specific state stored in the change machine in a little time). A state in which the currency type is lost is also referred to as near empty, and other obstacles (for example, a physical failure, a full state in which the currency type is full, a coin jam state, and the like). In the following description, when a failure is simply described, it indicates a failure of the change machine 209. In the present embodiment, the near end includes a state in which a specific currency type or all the currency types are completely lost.

  FIG. 17A shows an example in which two products, canned beer and asparagus, are registered, and the total is 383 yen. Further, since a product is registered, a subtotal button BT10 is also displayed. FIG. 17B is a diagram illustrating a registration screen when a failure occurs (hereinafter, also referred to as a “failure registration screen”). When a failure occurs, a pop-up 301 is displayed on the registration screen. The pop-up 301 displays the message "Cash cannot be settled due to change machine failure. Wait for customer input or select issuance of accounting ticket." At this time, since the customer side display unit 205 displays a button that can be input by the customer, it indicates that it is possible to wait for the input or issue a voucher at the discretion of the clerk. .

  Further, in FIG. 17B, the subtotal button BT10 is grayed out and cannot be operated. This makes subtotaling impossible. If no subtotal has been calculated, it is impossible to settle the account. Therefore, when a failure occurs, execution of the adjustment process is prohibited. Also, in FIG. 17B, a bill issue reservation button 302 is displayed. This is pressed when the clerk decides to issue a bill, and the bill is issued after the registration of the product is completed.

  FIG. 18 is a diagram showing two types of screens displayed on the customer display unit 205 when a failure occurs. FIG. 18A is a diagram illustrating a screen (hereinafter, also referred to as “screen A”) displayed when a failure occurs before the customer selects a payment method. FIG. 18B is a diagram showing a screen (hereinafter, also referred to as “screen B”) displayed when a failure occurs after the customer deposits cash into change machine 209.

  A pop-up 311 is displayed on the screen A. The pop-up 311 displays "A change has occurred in the change machine. Cash cannot be settled. The following settlement methods are available." The pop-up 311 displays buttons indicating “credit”, “electronic money”, and “cash settlement at another terminal” as settlement methods that can be selected by the customer. “Credit” indicates payment by credit card at the POS terminal 20 in which the product is registered. “Electronic money” indicates settlement by electronic money at the POS terminal 20 in which a product is registered. “Cash adjustment at another terminal” indicates cash adjustment at another terminal other than the POS terminal 20 in which the product is registered. From these three settlement methods, the customer can press the desired settlement method or the clerk can press the above-mentioned bill issue reservation button 302. In the following description, settlement by a settlement method using credit and electronic money may be referred to as non-cash settlement.

  On the screen B, a pop-up 312 is displayed. In the pop-up 312, it is displayed that "The change machine has failed. The cash settlement cannot be performed. The following settlement methods are possible." In addition, the pop-up 312 includes, as payment methods that the customer can select, “Refund the deposit and settle it with another terminal”, “Settle the deposit with another terminal without refund”, “Settle the balance with credit”, And a button indicating "payment of remaining money with electronic money" is displayed. “Refund the deposit amount and settle it with another terminal” indicates that the cash deposited in the change machine 209 is refunded as it is, and the other terminal other than the POS terminal 20 in which the product is registered is settled with cash. "Payment at other terminal without refund of deposit" indicates that the cash deposited in change machine 209 is not refunded, but the remaining balance is settled by cash at another terminal other than POS terminal 20 in which the product is registered. “Payment of remaining balance by credit” indicates payment by credit card at the POS terminal 20 in which the product is registered. “Electronic money” indicates settlement by electronic money at the POS terminal 20 in which a product is registered. From these four settlement methods, the customer can press the desired settlement method or the clerk can press the above-mentioned bill issue reservation button 302. In addition, when the cashier's ticket issuance reservation button 302 is pressed after cash is deposited, the deposited amount is refunded.

  As described above, when a change occurs in the change machine 209 and the payment is performed by the cash settlement method, the execution of the payment processing is prohibited in the POS terminal 20 in which the product is registered, and the payment is performed by another terminal. The transaction is completed. That is, the operation mode of the POS terminal 20 is forcibly switched from the normal mode (standard mode) to the semi-self mode (registration only mode). Further, in the case where the settlement process is executed by a non-cash settlement method, the execution of the settlement process is not prohibited. In the state where the above-described registration screen is displayed, the total amount is unknown because it is before the subtotal, but after the subtotal, the total amount is determined. Therefore, for example, when a near-end occurs as an obstacle and cash is not dispensed by the change machine 209, that is, when no change occurs, execution of the settlement process may not be prohibited.

  FIG. 19 shows a case where a near-end has occurred as a failure and “cash settlement at another terminal” is pressed on the pop-up 311 shown in FIG. Or a screen displayed when "payment at another terminal without refund of deposit" is pressed and subtotal button BT10 is pressed. Therefore, if the obstacle is not near-end or non-cash settlement is selected, it is not displayed.

  FIG. 19A is a diagram illustrating a screen (hereinafter, also referred to as “screen C”) displayed on the customer-side display unit 205. The screen C has an inquiry column 321. In the inquiry column 321, “Payment is just 383 yen, is it possible to deposit? Do you want to deposit?”, And “Yes” and “No” buttons are displayed. If the customer can deposit cash of the exact amount of payment, the customer can press "Yes" to settle the payment at the POS terminal 20. The customer presses “No” if it is not possible to deposit the cash of the payment amount. At this point, since no payment has been made, the end button BT40 for completing the transaction is grayed out and is inoperable, so that execution of the settlement process is prohibited.

  FIG. 19B is a diagram illustrating a screen (hereinafter, also referred to as “screen D”) displayed on the clerk-side display unit 210. On the screen D, a pop-up 322 indicating that the pop-up 321 is displayed is displayed. The pop-up 322 displays "Inquiring for settlement with just cash". Further, since the current total button BT20 for completing the transaction is grayed out and cannot be operated, execution of the settlement process is prohibited.

  Next, a flowchart illustrating the change machine failure handling process described above will be described. FIGS. 20, 21, and 22 are flowcharts showing change machine failure handling processing in the POS terminal 20. FIG. The flowcharts shown in FIG. 20, FIG. 21, and FIG. 22 show the processing from the time when the transaction of the previous customer is completed (or at the time of the start-up processing after turning on the power) to the time when the settlement or registration data is transmitted.

  In FIG. 20, the POS terminal 20 determines whether a failure has occurred (Step S101). If a failure has occurred (step S101: YES), the POS terminal 20 prohibits the use of the change machine 209 (step S102). Examples of the control for prohibiting the deposit machine 209 from receiving money include a control for not accepting the insertion of money itself, and a control for accepting the insertion of money but returning the inserted money as it is. The POS terminal 20 determines whether the status flag is 3 (Step S103). The status flag is a flag indicating the status of the POS terminal 20A by 1 to 4. Specifically, “1” indicates a state in which no failure has occurred in the POS terminal 20 and no payment method has been selected by the customer. “2” indicates a state in which no trouble has occurred in the POS terminal 20 and cash has been selected as a settlement method by the customer. “3” indicates a state in which a customer selects non-cash settlement as a settlement method regardless of whether or not a failure has occurred. Therefore, in step S103, it is determined whether the customer has selected the non-cash payment method as the payment method. “4” indicates a state in which a failure has occurred and the customer has selected cash as the settlement method. The state flag is initialized to “1” before the start of the flowchart.

  If the status flag is “3” in step S103 (step S103: YES), the POS terminal 20 displays that a failure has occurred on the clerk-side display unit 210 (step S104), and returns to FIG. Proceed to step S301. If the status flag is not “3” (step S103: NO), the POS terminal 20 determines whether the status flag is “4” (step S105). If the status flag is "4" (step S105: YES), it indicates that the fault has occurred again while the fault has already occurred. In this case, the settlement method and the like have already been dealt with for the failure that occurred first. Therefore, the POS terminal 20 proceeds to step S301.

  If the status flag is not “4” (step S105: NO), the POS terminal 20 grays out the subtotal button BT10 and prohibits the operation (step S106). Next, the POS terminal 20 inquires of the other terminals about the status and obtains an answer (step S107). Here, an inquiry is made as to whether or not the other terminal is in a state in which settlement is possible, a response is obtained, and the other terminal capable of settlement is stored.

  The POS terminal 20 determines whether the status flag is “1” (Step S108). If the status flag is “1” (step S108: YES), the POS terminal 20 displays a failure occurrence registration screen on the clerk side display unit 210, and displays a screen A on the customer side display unit 205 (step S109). ). The POS terminal 20 determines whether or not the customer has selected non-cash settlement (“credit” or “electronic money”) (step S110). When the non-cash settlement is selected (step S110: YES), the POS terminal 20 sets 3 to the state flag (step S111), releases the operation prohibition of the subtotal button BT10 (step S112), and proceeds to step S301. Proceed to.

  If the non-cash settlement has not been selected (step S110: NO), the POS terminal 20 determines whether or not “cash settlement at another terminal” has been selected (step S113). If “cash settlement at another terminal” is selected (step S113: YES), the POS terminal 20 sets another terminal in the settlement flag (step S114) and sets “4” in the status flag (step S114). (Step S115), the operation prohibition of the subtotal button BT10 is released (step S112), and the process proceeds to step S301.

  Note that the settlement flag is a flag that indicates whether the settlement is performed by another terminal or the settlement is performed by using a cash voucher when the settlement method is cash. When the settlement is performed at another terminal, the other terminal is set in the settlement flag, and when the settlement is performed with the check sheet, the check sheet is set in the settlement flag. In the program, the other terminal is represented by the numeral 1 and the bill is represented by the numeral 2. The settlement flag is initialized to “0” before the start of the flowchart.

  If “cash settlement at another terminal” is not selected (step S113: NO), the POS terminal 20 checks whether the accounting ticket has been selected by pressing the accounting ticket issuance reservation button 302 by the clerk. It is determined whether or not it is (step S116). If no check is selected (step S116: NO), the process returns to step S110. If the bill is selected (step S116: YES), the POS terminal 20 sets the bill in the settlement flag (step S117), and sets “4” in the state flag (step S118). The operation prohibition of the subtotal button BT10 is released (step S112), and the process proceeds to step S301.

  If the status flag is not “1” in step S108 (step S108: NO), the POS terminal 20 determines whether the status flag is “2” (step S119). If the status flag is “2” (step S119: YES), the POS terminal 20 proceeds to step S201 in FIG. 21 described below. If the status flag is not “2” (step S119: NO), the POS terminal 20 proceeds to step S301.

  In FIG. 21, the POS terminal 20 displays a failure registration screen on the clerk-side display unit 210, and displays a screen B on the customer-side display unit 205 (step S201). The POS terminal 20 determines whether or not the customer has selected non-cash payment (“pay the balance with credit” or “pay the balance with electronic money”) (step S202). When the non-cash settlement is selected (step S202: YES), the POS terminal 20 sets 3 to the state flag (step S203), releases the operation prohibition of the subtotal button BT10 (step S204), and proceeds to step S301. Proceed to.

  If the non-cash settlement is not selected (step S202: NO), the POS terminal 20 selects "Refund the deposit and settle it at another terminal" ("Refund and other terminal" in FIG. 21). It is determined whether or not it has been performed (step S205). If “repay the deposit and settle at another terminal” is selected (step S205: YES), the POS terminal 20 sets the other terminal in the adjustment flag (step S206), and sets the status flag to “4”. Is set (step S207). The POS terminal 20 performs a refund process (step S208), releases the operation prohibition of the subtotal button BT10 (step S204), and proceeds to step S301. If the money cannot be refunded due to the failure of the change machine 209, "Refund the deposit and settle it at another terminal" on the screen B is grayed out so that the customer cannot select it.

  If “pay the deposit and settle at another terminal” is not selected (step S205: NO), the POS terminal 20 sets “pay at the other terminal without refunding the deposit” (in FIG. 21, “ It is determined whether or not “other terminal without refund” is selected (step S209). When "payment at another terminal without refund" is selected (step S209: YES), POS terminal 20 sets another terminal in the payment flag (step S210) and turns on the payment flag. (Step S211). The deposit flag is a flag that indicates ON when there is a deposit by a customer and OFF when there is no deposit. The POS terminal 20 sets “4” in the status flag (step S212), releases the operation prohibition of the subtotal button BT10 (step S204), and proceeds to step S301.

  If "payment at other terminal without refund" is not selected (step S209: NO), the POS terminal 20 checks the billing reservation button 302 by the clerk and presses the checkout button. It is determined whether a ticket has been selected (step S213). If the check ticket has not been selected (step S213: NO), the process returns to step S202. If the check is selected (step S213: YES), the POS terminal 20 sets the check in the checkout flag (step S214) and sets the status flag to "4" (step S215). The operation prohibition of the subtotal button BT10 is released (step S204), and the process proceeds to step S301.

  In FIG. 22, the POS terminal 20 determines whether a barcode attached to a product has been scanned (step S301). If the barcode is scanned (step S301: YES), the POS terminal 20 registers the product (step S302), displays the registered product (step S303), and returns to step S101.

  If the barcode has not been scanned (step S301: NO), the POS terminal 20 determines whether the subtotal button BT10 has been pressed (step S304). If the subtotal button BT10 has not been pressed (step S304: NO), the process returns to step S101. If the subtotal button BT10 has been pressed (step S304: YES), it is determined whether the status flag is "4" (step S305). If the status flag is not “4” (step S305: NO), it indicates that no failure has occurred or that non-cash adjustment has been made, so even if a failure has occurred in the change machine 209. It can be settled. Therefore, the POS terminal 20 displays the small plan plane (Step S306), performs the settlement processing (Step S307), and ends the processing.

  When the status flag is "4" (step S305: NO), it indicates that a failure has occurred and the payment is cash. Therefore, the POS terminal 20 first determines whether or not the fault that has occurred is a fault that can be paid if the payment amount is exactly the same (step S308). In the present embodiment, the obstacle that can be paid if the payment amount is exactly is near-end as described above. If the payment amount is a failure that can be paid (step S308: YES), the POS terminal 20 displays the screen D on the clerk-side display unit 210 and the screen C on the customer-side display unit 205 (step S309). .

  The POS terminal 20 determines whether “Yes” is pressed on the screen C (Step S310). If "Yes" is pressed (step S310: YES), the POS terminal 20 displays the small plan plane (step S306), performs the payment processing (step S307) because the payment is possible, and ends the processing. .

  If it is determined in step S308 that the payment amount is not an obstacle for which payment is possible (step S308: NO), or if “NO” is pressed in step S310 (step S310: NO), the POS terminal 20 Grays out the total button BT20 and prohibits the operation (step S311). Next, the POS terminal 20 determines whether or not the payment flag indicates a bill (step S312). If the settlement flag indicates a bill (step S312: YES), the POS terminal 20 issues the bill (step S313) and ends the process.

  If the payment flag does not indicate a bill (step S312: NO), the POS terminal 20 transmits registration data to the other terminal because the integration flag indicates another terminal (step S314). The POS terminal 20 determines whether the deposit flag is on (Step S315). If the deposit flag is off (step S315: NO), the process ends. If the deposit flag is on (step S315: YES), the POS terminal 20 transmits the deposit information to the other terminal that has transmitted the registration data (step S316), and ends the processing. The deposit information is information indicating the denomination and the number of coins that the customer has deposited into the change machine 209.

  As described above, according to this embodiment, according to the state of the change machine 209, the execution of the settlement process by the cash settlement method is prohibited, and when the execution of the settlement process is prohibited, the registration process is performed. Output the generated registration data. As shown in the above embodiment, the output method includes a method of transmitting registration data and a method of issuing a check voucher. As a result, even if a failure occurs in the change machine, it is possible to make payment without re-registering the product.

  Further, as shown in FIG. 19 and the like, when cash is not dispensed by the change machine 209 in the checkout process, it is necessary to re-register the product in order to perform the checkout without prohibiting the execution of the checkout process. Without the need to settle on your own device.

  In addition, as shown in FIG. 18 and the like, if the execution of the settlement process is prohibited after the cash is received by the customer, it is possible to refund the money. Furthermore, if the execution of the payment process is prohibited after the customer has received the cash, the payment information relating to the payment can be transmitted to another device, so that the payment can be performed by the other device based on the payment information. .

  In the above-described embodiment, another device that can settle payment is used as an example of the destination of the registration data. However, such devices include a normal mode (standard mode), a full self mode, and a semi self mode (accounting only mode). And the POS terminal 20 operating on the Internet. In addition, when there are a plurality of other devices that can be settled, the POS terminal 20 to which the registration data is transmitted may be designated by a clerk or customer. In this case, it may be displayed in a mode different from the mode of the screen for designating the terminal to be settled in the normal full self mode (for example, to clearly indicate that a failure has occurred). By doing so, the clerk can be alerted.

  Further, when the POS terminal 20 is located at a position where the clerk can easily obtain change, such as when the clerk has a short moving distance, and the POS terminal 20 can settle the payment, the registration data and the deposit information are transmitted to the POS terminal 20. Alternatively, the clerk may receive the change and receipt at the POS terminal 20 and hand it to the customer. By doing so, the same screen as the screen on which no failure has occurred can be displayed on the customer side display unit 205, so that the customer can respond normally, and the customer does not move. Transactions can be completed without any hassle.

  Further, in the present embodiment, the POS terminal 20 in which the change machine 209 is provided on the customer side is described as an example. However, the change machine 209 is not provided on the customer side, and merchandise can be registered. (Including a drawer). Specifically, similarly to the present embodiment, when a failure such as near full, near end, or the drawer does not open, the registration data is transmitted to another device that can be settled and the device at the transmission destination performs the settlement. . By doing so, even if a failure occurs in the change machine, it is possible to make payment without re-registering the product.

  In the present embodiment, credit and electronic money are taken as examples of settlement in the non-cash settlement method. However, it is not necessary to use cash settlement, and for example, a prepaid card other than electronic money, points, gift certificates without change, etc. It may be. Further, in the case of performing payment using a prepaid card (including electronic money), balance inquiry and charge may be made possible.

  In the present embodiment, payment is possible if the payment amount is exactly the same at the time of subtotaling, but the present invention is not limited to this. For example, if the deposit amount is a change within a range in which payment can be made, the payment may be possible. Specifically, if the payment amount is 980 yen in a state where the one-yen coin is near-end, 1000 yen can be deposited. In actual operation, it may be determined whether or not change can be dispensed from the deposit amount assumed to be the payment amount, and the deposit amount that can be dispensed may be presented to the customer. If the payment amount is 980 yen, the POS terminal 20 determines 1000 yen, 1030 yen, 1080 yen, etc. as the assumed deposit amount, and determines whether or not the change amount can be dispensed with the deposited amount. Then, the customer is presented with a deposit amount at which the change can be dispensed. By doing so, the possibility of completing the settlement without moving the customer can be increased. In addition, the function of presenting a deposit amount with which a change can be dispensed to a customer may be applied to a merchandise sales data processing device that cannot transmit registration data to another device. In this case, for example, it is particularly effective in a store that operates only one product sales data processing device.

  As described above, the state of the change machine 209 according to the present embodiment includes not only near-full and near-end but also whether or not change is possible from the deposit amount assumed to be the payment amount (that is, whether the change machine can be dispensed). 209 for each denomination).

  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. Further, the “computer-readable recording medium” refers to a volatile memory (RAM) inside a computer system that becomes a server or a client when a program is transmitted through a network such as the Internet or a communication line such as a telephone line. And those holding programs for a certain period of time. Further, the above program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the "transmission medium" for transmitting a program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. Further, the program may be for realizing a part of the functions described above. Furthermore, what can realize the above-mentioned function in combination with a program already recorded in the computer system, a so-called difference file (difference program) may be used.
