FIG. 3B is a perspective view of the POS terminal 20 as viewed from a clerk. FIG. 4 is a diagram illustrating a configuration example of the POS terminal 20. 3 and 4, the same parts are denoted by the same reference numerals.

  Hereinafter, a configuration example of the POS terminal 20 illustrated in FIG. 4 will be described with reference to FIG. The POS terminal 20 includes a CPU 201, a ROM 202, a RAM 203, a hard disk 204, a customer-side display unit 205, a customer-side scanner unit 206, a card payment unit 208, a change machine 209, a clerk-side display unit 210, A key operation unit 211, a clerk-side scanner unit 212, a printing unit 213, a voice output unit 214, and a communication unit 215 are provided. These can communicate with each other via a bus. Note that reference numerals 211a, 211b, and 211c will be described later.

The CPU 201 is a central processing unit, and controls the operation of the POS terminal 20 by reading and executing a program stored in the ROM 202.
The ROM 202 is a read-only memory, and stores programs and various information used by the CPU 201.

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

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

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

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

(Overview of each operation mode)
Next, the operation mode of the POS terminal 20 will be described. The POS terminal 20 has a plurality of operation modes. Specifically, the POS terminal 20 has at least three types of operation modes (normal mode, full self mode, and semi self mode).

  The above-described operation mode is an operation mode during normal business (operation mode relating to registration processing and settlement processing), and is an aggregation mode for totalizing and inquiring sales and money, etc. It does not include a maintenance mode for performing maintenance work, a training mode for newcomer training, and the like.

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

  FIG. 5 and FIG. 6 are diagrams for explaining the outline of the operation mode of the POS terminal 20. FIG. 5 is a diagram illustrating an outline of the normal mode. FIG. 5A is a schematic diagram showing the flow of processing (registration processing, settlement processing) and the operation of a person (clerk, customer) in the normal mode, and FIG. 5B is an operation of the POS terminal 20 in the normal mode. 5 is a flowchart showing a basic flow of the first embodiment. FIG. 6 is a diagram schematically illustrating the full self mode. FIG. 6A is a schematic diagram showing the flow of processing (registration processing, settlement processing) and the operation of a person (customer) in the full self mode, and FIG. 6B is an operation of the POS terminal 20 in the full self mode. 5 is a flowchart showing a basic flow of the first embodiment.

(Normal mode)
The normal mode is, as shown in FIG. 5A, an operation mode in which a clerk executes a registration process and a customer executes a settlement process. That is, as shown in FIG. 5B, in the POS terminal 20 in the normal mode, the clerk is in the registration mode and the customer is in the checkout mode. That is, the POS terminal 20 in the normal mode operates in the registration accounting mode when viewed from the whole of the registration process to the settlement process.

  In the case of the normal mode, the clerk registers the purchased product of the customer on the clerk side (the clerk side scanner section 212, the clerk side display section 210, the key operation section 211). That is, the POS terminal 20 executes the registration processing of the purchased product by the operation of the clerk (scanning by the clerk-side scanner unit 212, touching the clerk-side display unit 210, and operation of the key operation unit 211) (FIG. 5 (A) ) Upper)).

  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. 5A). That is, the POS terminal 20 executes the settlement process by the operation of the customer (input of cash into the change machine 209, operation of the card settlement unit 208) (the lower part of FIG. 5A).

  That is, in the normal mode, as shown in FIG. 5 (B), the clerk first scans a product or the like (step S10: YES) and registers the product (step S11). After pressing a subtotal key (for example, a subtotal key displayed on the clerk side display unit 210 or a subtotal key arranged on the key operation unit 211) (step S30: YES), the customer side, for example, the change machine 209 (Step S50), and the process is completed. In step S30, the subtotal key is an operation key for completing the registration process, and may be referred to as a subtotal button, a registration completion key, a registration completion button, a checkout key, a checkout button, or the like.

  The customer may wait until the clerk completes the registration process (until the total amount is determined), or may put 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 (the upper part of FIG. 5A).

  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 selection of a payment method during the registration process (details will be described later).

  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. 5A). Further, the clerk may be absent during the checkout by the customer (the lower part of FIG. 5A). That is, during the checkout of the customer, the reception of the customer may be ended.

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

  In the normal mode, as described above, the clerk performs the registration process, and the customer's own terminal executes the settlement process using the registration information generated in the registration process (see FIG. 5). In addition to the above, the clerk performs a registration process, and transmits 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) (via the LAN 11). , Directly to another terminal, or transmitted to another terminal via the store controller 10 or a monitoring terminal (not shown). The same applies to the following. (Code, two-dimensional code, etc.), print on a medium, and issue as a bill. That is, the POS terminal 20 in the normal mode has a function of registering a product in its own terminal and making a payment in another terminal in addition to a function of registering a product in its own terminal and making a payment in the own terminal.

  The above-described function of registering a product in the own terminal and causing the other terminal to settle the payment is an original function of the semi-self mode. The semi-self mode is classified into a registration-only mode and an accounting-only mode. The POS terminal 20 in the semi-self mode (registration only mode) has a function of registering a product on its own terminal and causing the other terminal to settle the product. Specifically, the POS terminal 20 in the semi-self mode (registration-only mode) executes a registration process on the clerk side and transmits the registration information generated in the registration process to another terminal (or generated in the registration process). Encoded registration information, etc. are coded and printed on a medium, and issued as a cash voucher). The POS terminal 20 in the semi-self mode (accounting-only mode) has a function of adjusting a product registered in another terminal. Specifically, the POS terminal 20 in the semi-self mode (accounting-only mode) receives the registration information transmitted from the POS terminal 20 in the semi-self mode (registration-only mode) (or the POS in the semi-self mode (registration-only mode)). The transaction ticket issued at the terminal 20 is read), and a settlement process is executed.

  Note that the POS terminal 20 in the normal mode has a function of registering a product on its own terminal and making payment on another terminal, like the POS terminal 20 in the semi-self mode (registration only mode). The POS terminal 20 in the normal mode (similarly to the POS terminal 20 in the semi-self mode (accounting-only mode)) may have a function to settle the merchandise registered at another terminal, as in the POS terminal 20 in the semi-self mode. In other words, the POS terminal 20 in the full self mode or the POS terminal 20 in the normal mode receives registration information from another terminal (the POS terminal 20 in the semi-self mode (registration only mode), the POS terminal 20 in the normal mode, etc.) (or The accounting ticket may be read) and the settlement process may be executed.

(Full self mode)
The full self mode is an operation mode in which a customer performs a registration process and a customer performs a settlement process as shown in FIG. That is, as shown in FIG. 6 (B), the POS terminal 20 in the full self mode has both the registration mode and the accounting mode on the customer side. That is, the POS terminal 20 in the full self mode operates in the registration accounting mode when viewed from the entire registration processing to the settlement processing.

  In the case of 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). In other words, the POS terminal 20 executes the registration process of the purchased merchandise by the operation of the customer (scanning by the customer side scanner unit 206, touching the customer side display unit 205) (the upper part of FIG. 6A).

  When the registration process is completed, the customer confirms the total amount of the purchased merchandise on the customer side display unit 205, inserts cash into the change machine 209, or operates the card settlement unit 208 to make a payment (FIG. 6A ) Lower row). 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. 6A).

  That is, in the full self mode, as shown in FIG. 6B, 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.

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

(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, the normal mode image and the full self mode image are always displayed, and when the current operation mode of the own terminal is the normal mode, the normal mode image is displayed in a more prominent display mode than the full self mode image. When the current operation mode is the full self mode, the full self mode image may be displayed in a more prominent display mode 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 a monitoring terminal (not shown). 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, when the POS terminal 20 is on standby, a predetermined message (for example, see FIG. 7A) is displayed on the customer side display unit 205. It may be displayed. 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.

(Operation mode switching (transition))
Next, the transition of the operation mode of the POS terminal 20 will be described. The POS terminal 20 switches the operation mode (transition of the operation mode) in accordance with an explicit mode switching operation (also referred to as a mode transition operation) by a clerk. 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 of the mode switching button 211a (the surface touched by the hand) 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.

  Further, the POS terminal 20 can switch the operation mode without performing an explicit mode switching operation. For example, the POS terminal 20 receives time-related conditions such as an elapsed time (e.g., an elapsed time since the last operation) and a predetermined time (schedule), and receives information from other terminals (the POS terminal 20, the monitoring terminal, and the portable terminal). The operation mode is switched based on a condition regarding transmission and reception of information such as a mode switching instruction (mode switching instruction).

  Note that whether the POS terminal 20 switches the operation mode of its own terminal, regardless of whether the store clerk performs the explicit mode switching operation or not. The subsequent operation mode (latest operation mode) may be notified to another terminal.

  In the following description, it is assumed that the POS terminal 20-1 and the POS terminal 20-2 are in the normal mode. It is assumed that the POS terminal 20-3 is in the full self mode. In the following description, it is assumed that the POS terminal 20 switches its operation mode every time the mode switching button 211a is operated (pressed). However, in the following description, for convenience, the description regarding the semi-self mode is omitted, so that each time the mode switching button 211a is operated, the operation mode is basically switched from the normal mode to the full self mode, and from the full self mode. It is assumed that the operation mode is switched to the normal mode.

(Display example of POS terminal 20 in full self mode)

In FIG. 7A, 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. 7B shows the display contents of a registration screen in a state where two items of goods (daifuku mochi) are registered. Note that, when the registration start button BT30 is operated on the registration start screen shown in FIG. 7A, the POS terminal 20-3 displays a registration screen in which no product is registered yet. FIG. 7B shows a registration screen after a product (tea, Daifuku mochi) has already been registered for convenience.

  In FIG. 7B, an image GA01 at the lower left of the screen shows the state of the other terminal (POS terminal 20-1) (specifically, the normal mode). The image GA02 at the lower left of the screen shows the state of the other terminal (POS terminal 20-2) (specifically, the normal mode). The checkout button BT32 at the lower right of the screen is a button for instructing the end of product registration. The customer operates the checkout button BT32 after completing the product registration. The clerk call button BT33 is a button for calling a clerk. The customer operates the clerk call button BT33 when calling the clerk (for example, when the clerk needs support).

  The buttons BT35 to BT37 are buttons for switching the display language to English, Chinese, and Korean, respectively, as described above. The “vegetables” button BT38 is a button for displaying each vegetable preset key (see FIG. 9).

  FIG. 8A shows the contents of a payment screen (payment method selection screen) displayed when the payment processing is started. For example, when the checkout button BT32 is operated on the registration screen (see FIG. 7B), the POS terminal 20-3 displays a payment method selection screen as shown in FIG. 8A.

  FIG. 8 (B) shows the display contents of a settlement screen (payment screen) displayed when cash payment is started. For example, when cash is operated on the payment method selection screen (see FIG. 8A), the POS terminal 20-3 displays a payment screen as shown in FIG. 8B.

  FIG. 8C 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. 8C.

  FIG. 8D shows the display contents of the settlement screen (change screen) displayed when the change is released. For example, when the end (receipt) button BT40 is operated on the payment screen (FIG. 8C), the POS terminal 20-3 displays a change screen as shown in FIG. 8D.

  FIG. 8E shows the display contents of the settlement screen (receipt screen) displayed when the change is removed. For example, when the change is removed from the exit 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. 8F shows a sleep screen displayed in the sleep mode (sleep state).

  Note that the POS terminal 20-3 displays a registration start screen (FIG. 7A) after displaying the receipt screen (FIG. 8E). 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 occurs, the change screen (FIG. 8C) may be changed to the receipt screen (FIG. 8E) without displaying the change screen (FIG. 8D). .

(Display example of POS terminal 20 in normal mode)
9 to 14 show display examples on the POS terminal 20 in the normal mode. More specifically, FIG. 9A, FIG. 10A, FIG. 11A, FIG. 12A, FIG. 13A, and FIG. It is a display example in the salesclerk side display part 210 of 20-1. 9 (B), 10 (B), 11 (B), 12 (B), 13 (B) and 14 (B) show the customers of the POS terminal 20-1 in the normal mode. 6 is a display example on the side display unit 205.

  FIG. 9A shows the display contents on the registration screen in the initial state on the clerk side display unit 210. In the following description, the initial state is a state in which processing is not proceeding, for example, a state in which no product has been registered, and nothing has been done for payment (settlement), unless otherwise specified. In a state where no payment method has been selected, no cash has been entered, and no gift certificates have been registered, etc., and nothing has been done about the customer yet (a state in which a membership card, etc. has not been read, etc.) is there.

  In FIG. 9A, a tab area T1 at the upper right of the screen is a tab corresponding to each display content (display screen). The POS terminal 20-1 interrupts the registration process of the customer (the reason for the interruption is to return to the store for adding a purchased product, etc.), and the registration process of the next customer is possible. In other words, the POS terminal 20-1 displays a new registration screen for the next customer while holding (storing) the display content (registration content) of the registration screen for the customer based on the operation of the clerk. In the example shown in FIG. 9A, the number of tabs is one (tab area T1), but the POS terminal 20-1 displays a number of tabs corresponding to the number of registered screens (number of customers) in progress (tabs). The registration screen to be activated (activated) is switched in accordance with the operation (pressing) of the areas T1, T2, T3,...) And tabs.

  In the tab area T1, information for identifying the tab from other tabs (the number “1” in the example of FIG. 9A) is displayed. Further, in the tab area T1, a display field HR01 for displaying a deposit amount from a customer is provided. Although not shown in the example shown in FIG. 9A, various information (described later) other than the above is displayed in the tab area T1.

  The image GA02 at the lower left of the screen shows the state of the other terminal (POS terminal 20-2) (specifically, the normal mode). Image GA03 at the lower left of the screen shows the state of the other terminal (POS terminal 20-3) (specifically, the full self mode).

  FIG. 9B shows display contents on the customer side display unit 205 in an initial state. That is, when the POS terminal 20-1 displays the registration screen on the clerk-side display unit 210 as shown in FIG. 9A, the POS terminal 20-1 displays the registration screen on the customer-side display unit 205 as shown in FIG. A small screen (small window) SG01 is superimposed and displayed on the settlement screen (payment screen).

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

  The POS terminal 20-1 displays the registration screen shown in FIG. 9A on the clerk-side display unit 210 when the clerk registers canned beer from the state in which the registration screen of FIG. 9A is displayed on the clerk-side display unit 210. The registration screen as shown in is displayed.

  In FIG. 10A, a subtotal button BT10 at the lower right of the screen is a button for instructing the end of product registration. The clerk operates (touches) the subtotal button BT10 after completing the product registration.

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

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

  The check voucher button BT15 is a button for causing the print unit 213 to issue a check voucher. The clerk operates the bill button BT15 when the POS terminal 20 that has read the bill (the POS terminal 20 from which the customer has read the bill) executes the processing.

  When the POS terminal 20 in the normal mode and the POS terminal 20 in the full self mode are compared as the POS terminal 20 to which the registration information is transmitted, the POS terminal 20 in the full self mode is higher than the POS terminal 20 in the normal mode. Is preferable as the transmission destination of the registration information. Since the POS terminal 20 in the normal mode is basically operated by a clerk (see FIG. 5A), processing (for example, registration processing, customer correspondence, etc.) continuously exists and registration is performed. Even if you send the information, it is likely that it will not be processed immediately, and even if it is vacant (even if there is no clerk or customer), basically leave it open to respond immediately to the customer who wants to support the clerk On the other hand, the POS terminal 20 in the full self mode can process the registration information immediately after sending if there is no customer. Even if there is a customer, the POS terminal 20 can process the registration information simply in order. This is because such problems are unlikely to occur.

  In view of the above, the clerk is notified of whether or not it is preferable as the POS terminal 20 to which the registration information is to be transmitted, or which is more preferable when there are a plurality of transmission destinations of the registration information. As an example, in FIG. 10A, the outline of the 20-3 cash register button BT13 corresponding to the POS terminal 20-3 in the full self mode, which is relatively preferable as the transmission destination of the registration information, is indicated by a solid line. The outline of the 20-2 register button BT12 corresponding to the POS terminal 20-2 in the normal mode, which is relatively unfavorable, is indicated by a broken line. The above-described notification based on the outline portion is an example, and the clerk determines whether the POS terminal 20 as the destination of the registration information is preferable, or which is more preferable when there are a plurality of destinations of the registration information. The notification mode is not limited as long as can be recognized. For example, if it is relatively unfavorable, the background color of the button may be displayed in gray down, or a penalty mark or hatching may be added to the entire button. The display size, shape, and display position of the button may be changed depending on whether or not the POS terminal 20 is the destination of the registration information, or some information (such as “priority” or “recommended”) may be assigned to the button. Badge-like image).

  When the POS terminal 20-1 displays the registration screen as shown in FIG. 10A on the clerk-side display unit 210, the POS terminal 20-1 displays a small screen as shown in FIG. The screen SG01 is superimposed and displayed on the settlement screen (payment screen). The total amount was 0 yen on the settlement screen (payment screen) of FIG. 9B because no product was registered, but on the settlement screen (payment screen) of FIG. Is registered, the total amount is 215.

  The POS terminal 20-1 displays the registration screen of FIG. 10A on the clerk-side display unit 210 and, when 500 yen is inserted by the customer, displays the registration screen of FIG. The registration screen as shown in is displayed.

  Since the customer has inserted 500 yen, 500 is displayed in the display column HR01 at the upper right of the screen in FIG. 11 (A). In addition, since the payment is made at the own terminal (POS terminal 20-1) by inserting 500 yen, it is used when the payment is made at another terminal (POS terminal 20-2, POS terminal 20-3). Buttons (20-2 cash register button BT12, 20-3 cash register button BT13, check ticket button BT15) are not displayed (erased).

  When the POS terminal 20-1 displays the registration screen as shown in FIG. 11A on the clerk side display unit 210, the POS terminal 20-1 displays the settlement screen (payment screen) as shown in FIG. 11B. It is displayed on the customer side display unit 205. Since 500 yen has been inserted by the customer, the small screen SG01 has been deleted.

  In the POS terminal 20-1, two products (aspara) and three products (paste lunch) are registered by the clerk from the state where the registration screen of FIG. 11A is displayed on the clerk side display unit 210. When the customer further inputs 500 yen, a registration screen as shown in FIG. Since the customer has added 500 yen, 1000 is displayed in the display column HR01 in the upper right of the screen in FIG.

  When the POS terminal 20-1 displays the registration screen as shown in FIG. 12A on the clerk-side display unit 210, the POS terminal 20-1 displays the settlement screen (payment screen) as shown in FIG. It is displayed on the customer side display unit 205.

  When the clerk operates the subtotal button BT10 from the state in which the registration screen shown in FIG. 12A is displayed on the clerk-side display unit 210, the POS terminal 20-1 displays the POS terminal 20-1 in FIG. ), The small screen (small window) SG02 is displayed so as to be superimposed on the registration screen, and a checkout screen (payment screen) as shown in FIG. The small screen SG02 is for notifying the clerk of information related to settlement (total amount, device deposit amount (deposit amount)).

  When the customer operates the end (receipt) button BT40 from the state in which the payment screen (payment screen) of FIG. 13B is displayed on the customer side display unit 205, the POS terminal 20-1 displays the clerk side. The message screen MG1 is superimposed on the registration screen and displayed on the registration screen as shown in FIG. 14A in the unit 210, and the settlement screen (change screen) as shown in FIG. indicate.

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

  Although illustration is omitted in FIG. 14 and subsequent figures, the POS terminal 20-1 displays a payment screen similar to that shown in FIG. 8 (E) and later on the customer display unit 205 and a payment screen on the clerk display unit 210. Display the corresponding message.

(Operation after mode switching operation)
Subsequently, an operation after the mode switching operation will be described. Since the mode switching button 211a (see FIG. 3B) is a hardware key provided on the key operation unit 211, the clerk can operate the POS terminal 20 in any state (state). (In an extreme case, even if the POS terminal 20 is not turned on or is out of order, it is possible to press the POS terminal 20 itself). That is, the POS terminal 20 can perform a mode switching operation in various situations. In other words, the status of the POS terminal 20 at the time of the mode switching operation is various.

For the above reasons, at the time of the mode switching operation, the POS terminal 20 performs an operation according to the situation at the time of the mode switching operation (various situations in which the POS terminal 20 is operating normally instead of the extreme case described above). . That is, when the mode switching operation is performed, the POS terminal 20 generally switches the operation mode (every time the mode switching button 211a is operated, basically, the operation mode switches from the normal mode to the full self mode, Although it has been described that the operation mode is switched from the full self mode to the normal mode), more specifically, the POS terminal 20 determines whether or not to switch the operation mode depending on the state (state) in which the mode switching operation is performed. The behavior is different. In other words, the POS terminal 20 controls the operation after the mode switching operation according to the situation (state) at the time of the mode switching operation.
Hereinafter, a specific example will be described.

(initial state)
When the mode switching button 211a is operated in the initial state, the POS terminal 20-1 in the normal mode performs a mode switching process for switching the operation mode from the normal mode to the full self mode. The mode switching process is also called a mode transition process. Therefore, in other words, using the mode transition process, the POS terminal 20-1 in the normal mode changes the operation mode from the normal mode to the full self mode when the mode switching button 211a is operated in the initial state. Then, a mode shift process for shifting is executed.

  The initial state is, as described above, a state in which no product is registered yet, and a state in which no payment (settlement) has yet been made (selection of a payment method, insertion of cash, registration of gift certificates, etc.). (Such as a state in which a member card or the like is not read). That is, the initial state is a state in which merchandise has not been registered, cash has not been inserted, a payment type has not been selected, gift certificates have not been registered, and customer information has not been acquired.

  For example, as shown in FIG. 9A, when the POS terminal 20-1 in the normal mode displays the registration screen in the initial state on the clerk side display unit 210, when the mode switching button 211a is operated. In FIG. 7A, the mode is switched from the normal mode to the full self mode (the mode switching process is executed), and a registration start screen is displayed on the customer side display unit 205 as shown in FIG.

(Only cash input)
When the POS terminal 20 is in the cash input alone state (commodity not registered, cash inserted, payment type not selected, gift certificate not registered, customer information not obtained), the mode switching button 211a is operated , The inserted cash is released (payment information cancel processing is executed), and the initial state is reached.

  FIG. 15A is a display example on the POS terminal 20 in the normal mode. Specifically, FIG. 15 (A) shows the state of cash input alone (product not registered, cash inserted (15 yen has been inserted in FIG. 15 (A)), settlement type not selected, gift certificate not registered, customer 9 shows a registration screen on the clerk-side display unit 210 in a state where information has not been acquired.

  FIG. 15B is a display example on the POS terminal 20 in the normal mode. Specifically, FIG. 15B shows a message screen MG1 (see FIG. 14B) superimposed and displayed on the registration screen (see FIG. 9A) in the clerk-side display unit 210 in the initial state. Is shown.

  For example, as shown in FIG. 15A, the POS terminal 20-1 in the normal mode operates the mode switching button 211a when the registration screen of the cash-in-only state is displayed on the clerk-side display unit 210. In this case, the inserted cash is released (and the payment information canceling process is executed), and the message screen MG1 is superimposed on the clerk-side display unit 210 as shown in FIG. 15B. Display the registration screen of the initial state. Note that, since the cash has been discharged, 0 is displayed in the display field HR01 of the tab area T1 in FIG. 15B.

(Payment type selection alone)
When the POS terminal 20 is in the settlement type selection alone state (commodity not registered, cash not inserted, settlement type selected, gift certificate not registered, customer information not acquired), the mode switching button 211a is operated. In this case, the selected payment type is canceled (performs the payment type information cancellation process), and the initial state is set.

  FIG. 16A is a display example on the POS terminal 20 in the normal mode. Specifically, FIG. 16 (A) shows the settlement type selection alone state (commodity not registered, cash not inserted, settlement type selected (“Credit” has been selected in FIG. 16 (A)), and gift certificates not registered , Customer information has not been acquired). The icon I1 in the tab area T1 indicates that the payment type “credit” has been selected.

  FIG. 16B is a display example on the POS terminal 20 in the normal mode. Specifically, FIG. 16B shows a state in which the message screen MG2 is superimposed and displayed on the registration screen (see FIG. 9A) on the clerk-side display unit 210 in the initial state.

  The message screen MG2 notifies the clerk of the payment type (specifically, the fact that the selection of the payment type has been canceled). The POS terminal 20 deletes the message screen MG2 superimposed on the registration screen and displayed without being operated by the clerk (for example, automatically after a predetermined time has elapsed). Note that the POS terminal 20 may delete the message screen MG2 superimposed and displayed on the registration screen according to the operation of the clerk (such as touch on the message screen MG2).

  For example, as shown in FIG. 16A, the POS terminal 20-1 in the normal mode, when displaying the registration screen of the settlement type selection alone state on the clerk side display unit 210, operates the mode switching button 211a. When the operation is performed, the selected payment type is canceled (the payment type information cancellation process is executed), and the message screen MG2 is superimposed on the clerk-side display unit 210 as shown in FIG. Display the registration screen in the initial state. Since the payment type has been canceled, the icon I1 in the tab area T1 has been deleted in FIG. 16B.

(Individual registration of gift certificates)
The mode switching button 211a is operated when the POS terminal 20 is in the state of the gift certificate registration alone (commodity not registered, cash not inserted, settlement type not selected, gift certificate registered, customer information not acquired). In this case, the registered gift certificates are canceled (the gift certificate information cancellation process is executed), and the initial state is set.

  For example, although the illustration of the POS terminal 20-1 in the normal mode is omitted, the mode switching button 211a is operated when the registration screen of the gift certificate registration alone state is displayed on the clerk side display unit 210. In this case, the registered gift certificates are canceled (while executing the gift certificate information canceling process) and also omitted from the illustration, but the shop assistant display unit 210 displays the gift certificates (specifically, A registration screen in an initial state is displayed in which a message screen for notifying a clerk that the registration of gift certificates has been canceled is superimposed.

(Only product registration)
When the POS terminal 20 is in the product registration alone state (product registered, cash not inserted, payment type not selected, gift certificate not registered, customer information not acquired), the mode switch button 211a is operated. , The merchandise information is canceled (the merchandise information canceling process is executed), and an initial state is set.

  For example, as shown in FIG. 10A, the POS terminal 20-1 in the normal mode operates the mode switching button 211a when the registration screen of the product registration alone state is displayed on the salesclerk side display unit 210. In this case, the registered product is canceled (along with executing the product information canceling process) and, although not shown, the store clerk-side display unit 210 displays the product (specifically, the registration of the product). A registration screen in an initial state is displayed in which a message screen notifying the clerk of the cancellation is superimposed.

(Customer information acquisition alone)
When the POS terminal 20 is in the customer information acquisition alone state (commodity not registered, cash not inserted, payment type not selected, gift certificate not registered, customer information acquired state), the mode switching button 211a is operated. In this case, the acquired customer information is taken over (the customer information takeover process is executed), and the mode is switched from the normal mode to the full self mode (the mode switching process is executed).

  FIG. 17A is a display example on the POS terminal 20 in the normal mode. Specifically, FIG. 17 (A) shows the customer information acquisition alone state (commodity not registered, cash not inserted, settlement type not selected, gift certificate not registered, customer information acquired (FIG. 17 (A) shows membership card 2 shows the registration screen on the clerk-side display unit 210 in the state of (acquired information). The icon I2 in the tab area T1 indicates that the member card information has been acquired.

  FIG. 17B is a display example on the POS terminal 20 in the full self mode. Specifically, FIG. 17B shows a state in which “member number xxx” is displayed on the registration start screen (see FIG. 7A) on the customer-side display unit 205. “Member number XXX” is the transferred customer information (specifically, information of the member card).

  For example, when the POS terminal 20-1 in the normal mode displays the registration screen of the customer information acquisition alone state on the salesclerk side display unit 210 as shown in FIG. When operated, the acquired customer information (member number which is the information of the member card) is taken over (performs customer information takeover processing), and the mode is switched from the normal mode to the full self mode (performs the mode switching processing). 17) Then, as shown in FIG. 17 (B), a registration start screen displaying “member number XXX” is displayed on the customer side display unit 205. Note that the customer information is also taken over (displayed) on screens subsequent to the registration start screen (registration screen in FIG. 7B, all or a part of each settlement screen in FIGS. 8A to 8E). ).

(Cash input product registration status)
When the POS terminal 20 is in the cash input product registration state (product registration, cash input, payment type not selected, gift certificate not registered, customer information not obtained), the mode switching button 211a is operated. In this case, the payment information and the product information are taken over (the payment information takeover process and the product information takeover process are executed), and the mode is switched from the normal mode to the full self mode (the mode switching process is executed).

  FIG. 18A is a display example on the POS terminal 20 in the normal mode. Specifically, FIG. 18 (A) shows the state of registering cash-added products (product registered (canned beer registered in FIG. 18 (A)), and cash inserted (15 yen in FIG. 18 (A)) ), Payment type not selected, gift certificates not registered, and customer information not acquired).

  FIG. 18B is a display example on the POS terminal 20 in the full self mode. Specifically, FIG. 18B shows a state in which registration information of canned beer and “deposit 15 yen” are displayed on the registration screen (see FIG. 7B) on the customer side display unit 205. Is shown. The registration information of the canned beer is the inherited product information. "Deposit 15 yen" is the transferred deposit information.

  For example, when the POS terminal 20-1 in the normal mode displays the registration screen of the cash-in-commodity registration state on the clerk-side display unit 210 as shown in FIG. In the case of the operation, the deposit information of the inserted cash (15 yen) and the registered product information (canned beer information) are taken over (the payment information takeover process and the product information takeover process are executed). Then, the mode is switched from the normal mode to the full self mode (the mode switching process is executed), and as shown in FIG. 18B, the registered information of the canned beer and “15 yen deposit” are displayed on the customer side display unit 205. Display the registered screen. Note that the customer information may be taken over (displayed) on a screen subsequent to the registration screen. In addition, since “deposit 15 yen” already exists (since cash is treated as being selected), the payment method selection screen (see FIG. 8A) may not be displayed.

(Cash input voucher registration status)
When the POS terminal 20 is in the cash input gift certificate registration state (commodity not registered, cash inserted, payment type not selected, gift certificate registered, customer information not acquired), the mode switching button 211a is operated. In this case, the payment information and the gift certificate information are taken over (the payment information handover process and the gift certificate information handover process are executed), and the mode is switched from the normal mode to the full self mode (the mode switching process is executed). ).

  For example, although the illustration of the POS terminal 20-1 in the normal mode is omitted, the mode switching button 211a is operated when the registration screen of the cash-in gift certificate registration state is displayed on the clerk-side display unit 210. In this case, the deposit information of the inserted cash and the registered gift certificate information are taken over (performing the deposit information transfer process and the gift certificate information transfer process), and the normal mode is changed to the full self mode. Switching (performing the mode switching process), a registration screen displaying gift certificate information and deposits is displayed on the customer-side display unit 205 (not shown).

(Customer detection related)
The POS terminal 20 may include a sensor (for example, a camera for photographing the customer side) that can detect whether or not there is a customer around the terminal (particularly, the customer side). Alternatively, a sensor (for example, a camera for photographing the customer side) that can detect whether or not there is a customer around the POS terminal 20 (particularly on the customer side) may be provided on the ceiling or the wall. If the configuration is such that it is possible to detect whether there is a customer around the POS terminal 20 (especially on the customer side), when the mode switching button 211a is operated, the customer becomes The behavior may be changed depending on whether the operation mode is switched or not, depending on whether the operation mode is switched or not.

  Note that the POS terminal 20 may be used in place of or in addition to the method using the sensor, based on whether or not operation has been performed for a predetermined time (whether or not a predetermined time has elapsed since the last operation). Alternatively, it may be determined whether there is a customer around the terminal.

(Customer detection alone)
When the POS terminal 20-1 in the normal mode is in the customer detection only state (customer detection present, merchandise not registered, cash not inserted, payment type not selected, gift certificate not registered, customer information not acquired), When the mode switching button 211a is operated, the mode is simply switched from the normal mode to the full self mode (the mode switching process is executed), and the registration start screen is displayed on the customer-side display unit 205. Note that the state is an initial state (a state in which a product has not been registered, cash has not been inserted, a payment type has not been selected, a gift certificate has not been registered, and customer information has not been obtained). I have.

(Cash input customer detection status)
When the POS terminal 20 is in the cash input customer detection state (customer detection present, merchandise unregistered, cash inserted, payment type unselected, gift certificate unregistered, customer information unacquired), the mode switching button 211a Is operated, the payment information is taken over (the payment information handover process is executed), the mode is switched from the normal mode to the full self mode (the mode switching process is executed), and the deposit is displayed on the customer side display unit 205. Display the displayed registration screen.

(Product registration customer detection status)
When the POS terminal 20 is in the merchandise registration customer detection state (customer detection is present, merchandise is registered, cash is not inserted, settlement type is not selected, gift certificates are not registered, and customer information is not acquired), the mode switching button 211a Is operated, the product information is taken over (the product information takeover process is executed), the mode is switched from the normal mode to the full self mode (the mode switching process is carried out), and the product information is displayed on the customer side display unit 205. Display the displayed registration screen.

  FIG. 19 is an explanatory diagram illustrating various operations after the mode switching operation from the normal mode to the full self mode. More specifically, FIG. 19 shows the states exemplified above (initial state, cash input only state, settlement type selection only state, gift certificate registration only state, product registration only state, customer information acquisition single state, cash input Various states after the mode switching operation from the normal mode to the full self-mode in each state, including the commodity registration state, cash-in gift certificate registration state, customer detection alone state, cash-in customer detection state, and commodity registration customer detection state). Are summarized.

  As also shown in the upper right of FIG. 19, when the operation mode is switched from the normal mode to the full self mode, the registration on the customer side which has been prohibited is permitted, and the transmission of the registration information to another terminal which has been prohibited is prohibited. The issuance of the approved accounting voucher is prohibited.

  In the above, as specific examples of the information displayed in the tab area T1, the display field HR01 (that is, the deposit amount), the icon I1 (that is, the fact that the payment type “credit” has been selected), and the icon I2 (that is, In the tab area T1, for example, it is displayed that a payment type other than “credit” has been selected and that a gift certificate has been registered. Is also good. In addition, instead of or in addition to the above, the tab area T1 indicates that a customer has been detected and that the total input amount (or the sum of the input total amount and the total amount of gift certificates) is equal to or greater than the total item amount. May be displayed.

  FIG. 20 is an explanatory diagram illustrating a process that can be executed after the mode switching operation. Specifically, FIG. 20A summarizes each processing executed according to the state after the mode switching operation. FIG. 20B summarizes messages displayed according to the state after the mode switching operation.

  The “settlement type information transfer process” illustrated in FIG. 20A is executed in “settlement-related + customer detection-related” in FIG. More specifically, the process is executed when the state of “payment type selection customer detection state (not shown)” is (b) + (e). The “customer information cancellation process” will be described later.

  As shown in FIGS. 20A and 20B, the process and the message correspond. For example, the message on the message screen MG1 in FIG. 15B corresponds to the “payment cancellation message” shown in FIG. 20B, and the “payment information cancellation processing” shown in FIG. When displayed. Also, for example, the message on the message screen MG2 in FIG. 16B corresponds to the “settlement type cancellation message” illustrated in FIG. 20B, and the “settlement type information cancellation process” illustrated in FIG. Displayed when a call is made.

(Operation example of POS terminal 20)
FIG. 21A is a flowchart illustrating an example of the operation of the POS terminal 20. Specifically, the flowchart of FIG. 21A shows an example of an operation when a mode switching operation is performed on the POS terminal 20-1 in the normal mode. That is, the flowchart in FIG. 21A starts when the POS terminal 20-1 in the normal mode detects the operation of the mode switching button 211a.

Step S100: The POS terminal 20-1 checks the registration status of the product. That is, the POS terminal 20-1 determines whether a product is registered. The POS terminal 20-1 stores (temporarily stores) the confirmation result (determination result) in the RAM 203 or the like.

Step S110: The POS terminal 20-1 checks the state of cash input. That is, the POS terminal 20-1 determines whether or not cash has been inserted. The POS terminal 20-1 stores (temporarily stores) the confirmation result (determination result) in the RAM 203 or the like.

Step S120: The POS terminal 20-1 confirms the state of selection of the payment type (payment method). That is, the POS terminal 20-1 determines whether the payment type is selected. The POS terminal 20-1 stores (temporarily stores) the confirmation result (determination result) in the RAM 203 or the like.

Step S130: The POS terminal 20-1 checks the registration status of gift certificates (such as coupons). That is, the POS terminal 20-1 determines whether or not gift certificates are registered. The POS terminal 20-1 stores (temporarily stores) the confirmation result (determination result) in the RAM 203 or the like.

Step S140: The POS terminal 20-1 confirms the state of acquisition of customer information (member number and the like). That is, the POS terminal 20-1 determines whether the customer information has been acquired. The POS terminal 20-1 stores (temporarily stores) the confirmation result (determination result) in the RAM 203 or the like.

Step S150: The POS terminal 20-1 checks the status of the customer detection. That is, the POS terminal 20-1 determines whether a customer has been detected. The POS terminal 20-1 stores (temporarily stores) the confirmation result (determination result) in the RAM 203 or the like.

Step S160: The POS terminal 20-1 executes an operation (see FIG. 19) according to the above-described confirmation result. Then, the flowchart of FIG. 21A ends.

  In FIG. 21A, the state of merchandise registration, the state of cash input, the state of selection of a settlement type, the state of registration of gift certificates, the state of acquisition of customer information, and the state of customer detection are arranged in this order. Although confirmation was made, the order of confirmation is not limited to the order shown in FIG. That is, any state may be checked first. In FIG. 21 (A), the state of merchandise registration, the state of cash input, the state of settlement type selection, the state of registration of gift certificates, the state of customer information acquisition, and the state of customer detection are confirmed. However, when the operation to be processed is determined, the subsequent confirmation processing may be omitted.

  The processing (steps S160A, S160B, S160C, and S160D) shown in the flowcharts of FIGS. 21B, 21C, 22A, and 22B is the same as that of FIG. 9A is an example of the process of step S160 in FIG. The processing shown in the flowchart of FIG. 22C is a modified example of the processing (step S160B) shown in the flowchart of FIG.

(In the initial state)
The flowchart in FIG. 21B illustrates a process (step S160A) corresponding to the confirmation result (initial state) when the confirmation result is in the initial state, as an example of step S160 in FIG. 21A. .

Step S170A: The POS terminal 20-1 executes a mode switching process. That is, the POS terminal 20-1 switches from the normal mode to the full self mode. Then, the process (step S160A) of the flowchart in FIG. 21B ends.

  As described above, as shown in FIG. 21B, when the state at the time of the mode switching operation is the initial state (when the mode switching operation is performed during the initial state), the mode switching processing is performed. Is executed, and the mode is switched to the full self mode.

(In the case of cash input alone)
The flowchart of FIG. 21C illustrates a process according to the confirmation result (cash-only state) when the confirmation result is the cash-only state as an example of step S160 in FIG. 21A (step S160B). Is shown.

Step S161B: The POS terminal 20-1 executes a payment information canceling process.
Step S162B: The POS terminal 20-1 executes a payment cancellation message.

Step S163B: The POS terminal 20-1 determines whether or not the cash has been removed. That is, the POS terminal 20-1 determines whether or not the cash discharged in the payment information canceling process has been removed by using a sensor or the like. If it has not been removed, the process is repeated. If it has been removed, the process of the flowchart in FIG. 21C (step S160B) ends.

  As described above, as shown in FIG. 21C, when the state at the time of the mode switching operation is the cash input alone state (when the mode switching operation is performed when the cash input is the sole state). Since the mode switching process is not executed, the mode is not switched to the full self mode. However, since the payment information canceling process is executed, the process returns to the initial state. Therefore, when the mode switching operation is performed again, the mode switching process is executed, and the mode is switched to the full self mode (see FIG. 21B).

(In the case of product registration alone)
The flowchart of FIG. 22A is an example of step S160 in FIG. 21A, and is a process (step S160C) according to the confirmation result (commodity registration only state) when the confirmation result is the commodity registration alone state. Is shown.

Step S161C: The POS terminal 20-1 executes a merchandise information cancellation process.
Step S162C: The POS terminal 20-1 displays a product cancellation message. Then, the processing of the flowchart in FIG. 22A (step S160C) ends.

  As described above, as shown in FIG. 22A, when the state at the time of the mode switching operation is the product registration alone state (when the mode switching operation is performed when the product registration is the single state). Since the mode switching process is not executed, the mode is not switched to the full self mode. However, since the product information canceling process is executed, the process returns to the initial state. Therefore, when the mode switching operation is performed again, the mode switching process is executed, and the mode is switched to the full self mode (see FIG. 21B).

(In the case of cash input product registration status)
The flowchart of FIG. 22B illustrates a process (step S160 in FIG. 21A) corresponding to the confirmation result (cash-incommodity registration state) when the confirmation result is the cash-incommodity registration state. S160D).

Step S161D: The POS terminal 20-1 executes a deposit information transfer process and a product information transfer process.
Step S162D: The POS terminal 20-1 displays a payment transfer message and a product transfer message.

Step S170D: The POS terminal 20-1 executes a mode switching process. That is, the POS terminal 20-1 switches from the normal mode to the full self mode. Then, the process of the flowchart in FIG. 22B (step S160D) ends.

  As described above, as shown in FIG. 22 (B), when the state at the time of the mode switching operation is the cash input product registration state (when the mode switching operation is performed while the cash ), The mode switching process is executed, and the mode is switched to the full self mode. In addition, since the payment information transfer process and the product information transfer process are performed, the payment information and the product information are transferred to the full self mode.

  In addition, after returning to the initial state after the mode switching operation, if the mode is not switched (for example, in the case of the cash input alone state in FIG. 21C, in the case of the product registration alone state in FIG. 22A), It has been described that the mode is switched if the mode switching operation is performed again after returning to the initial state. That is, it has been described that the mode switching operation may be performed again as needed after a series of processes started from step S100 in FIG. 21A is completed. Instead, the mode may be switched in the above-described series of processing.

(Select whether to switch modes from the screen)
The flowchart in FIG. 22C is a modified example of the process (step S160B) shown in the flowchart in FIG. 21C. Specifically, the processing after step S163B (YES) of the flowchart in FIG. 21C is shown.

Step S164B: Subsequent to step S163B (YES), the POS terminal 20-1 displays a small screen (not shown, in which a “Yes” button and a “No” button are arranged) for allowing the clerk to determine whether or not mode switching is necessary. .

Step S165B: The POS terminal 20-1 determines whether or not the “NO” button has been operated on the small screen. That is, it is determined whether or not the clerk has indicated that the mode is not to be switched. If the “NO” button is operated, the processing of the flowchart in FIG. 22C ends. If the “NO” button has not been operated, the process proceeds to step S166B.

Step S166B: The POS terminal 20-1 determines whether the “Yes” button has been operated on the small screen. That is, it is determined whether or not the clerk has indicated the intention to switch the mode. If the “Yes” button has been operated, the process proceeds to step S170B. If the “Yes” button has not been operated, the process returns to step S166B.

Step S170B: The POS terminal 20-1 executes a mode switching process. That is, the POS terminal 20-1 switches from the normal mode to the full self mode. Then, the processing of the flowchart in FIG. 22C ends.

  According to the example shown in FIG. 22C, the mode is switched as needed in a series of processes without performing the mode switching operation again. Note that FIG. 22 (C) describes an example of a cash input alone state, but the same applies to a commodity registration alone state. Also, when switching from the full self mode to the normal mode (see FIG. 23), or when using another criterion (such as processing on the clerk side or processing on the customer side) (see FIGS. 24 and 25), In the processing of the above, the mode may be switched as necessary.

  In the example shown in FIG. 22C, the mode is switched as needed (in accordance with the selection of the clerk), but the mode may be switched automatically (independent of the selection of the clerk). . That is, step S170B may be always executed after step S163B (YES). In the case of the product registration alone state, the case where the mode is switched from the full self mode to the normal mode (see FIG. 23), and the case where another criterion (the processing of the clerk or the processing of the customer) is used (FIG. 24, The same applies to FIG. 25).

  FIG. 23 is an explanatory diagram illustrating various operations after the mode switching operation from the full self mode to the normal mode. FIG. 19 summarizes the behavior (operation) after the operation of the mode switching button 211a when the current operation mode is the normal mode. FIG. 23 illustrates that the current operation mode is the full self mode. In this case, the behavior after the operation of the mode switching button 211a is summarized.

  As also shown in the upper right of FIG. 23, when the operation mode is switched from the full self mode to the normal mode, the registration on the customer side which has been permitted is prohibited, and the transmission of the registration information to another terminal which has been prohibited is permitted. Issuance of the prohibited accounting voucher is permitted.

  As shown in FIG. 23, when the current operation mode is the full self mode, the status is “payment-related + product-related”, “payment-related + customer detection-related”, “product-related + customer detection-related”, “ The behavior when “the number of settlement related is plural” is different from the case where the current operation mode shown in FIG. 19 is the normal mode mode. In other words, when the current operation mode is the full self mode, the information is taken over and the mode is switched to the full self mode (see FIG. 19). However, when the current operation mode is the normal mode, the information is held. The mode is not switched to the normal mode (see FIG. 23).

  As shown outside the table of FIG. 23, when “payment-related + product-related”, “payment-related + customer-detection-related”, “product-related + customer-detection-related”, and “payment-related multiple”, information May be taken over to switch to the normal mode. For example, a small screen (not shown; a “Yes” button and a “No” button are arranged) for allowing the clerk to decide whether or not the mode switching is necessary is displayed, and according to the clerk's selection (the clerk's intention display) (“Yes”). (When a button is operated), the information may be taken over and switched to the normal mode. Alternatively, the mode may be automatically switched to the normal mode (independent of the clerk's selection) by taking over the information.

  In addition, taking over and holding are common in that they are not canceled. For example, taking over and holding the inserted cash is common in that the cash is not discharged, and taking over and holding the selected payment type is that the payment type is not canceled. In common. Therefore, each process corresponding to “holding information” in FIG. 23 (for example, each process named as “$ information holding process”) is different from “@information inheriting process” in FIG. This is the same or similar (at most, a difference as to whether or not the mode is switched).

(Customer information cancellation processing)
Note that, in the above description, when the customer information is acquired (for example, in the case of the customer information acquisition alone state) at the time of operating the mode switching button 211a, the acquired customer information is described as being inherited ( 19 and 23), the acquired customer information may be canceled. That is, when the customer information has already been acquired when the mode switching operation is performed, the POS terminal 20 may execute the customer information cancellation process instead of the customer information takeover process. For example, if the customer information has already been acquired when the mode switching operation is performed, the POS terminal 20 causes the clerk to determine whether to take over or cancel the acquired customer information (not shown). A “takeover” button and a “cancel” button are arranged), and customer information may be taken over or canceled according to the intention of the clerk. When the customer information is canceled (when the customer information cancellation processing is executed), the mode may be switched or the mode may not be switched (see FIG. 22C).

  As described above, the POS terminal 20 displays the behavior (operation) after the operation of the mode switching button 211a at the time of the operation, the operation mode, the state of cash input, the state of selection of the settlement type, and the registration of gift certificates. , The state of merchandise registration, the state of customer information acquisition, and the state of customer detection (see FIG. 19, FIG. 23, etc.).

  Further, when the mode switch button 211a is operated, the POS terminal 20 differs from the mode switch process in place of or in addition to the mode switch process that should be performed by the operation of the mode switch button 211a, depending on the situation. Other processing (for example, payment information cancellation processing, payment information transfer processing, payment type information cancellation processing, payment type information transfer processing, gift certificate information cancellation processing, gift certificate information transfer processing, product information cancellation processing, product information transfer Process, customer information cancellation process, customer information takeover process).

(Other examples)
FIG. 24 and FIG. 25 are explanatory diagrams illustrating various operations after the mode switching operation. FIGS. 19 and 23 show that the behavior (operation) after the operation of the mode switching button 211a is the state of cash input, the state of payment type selection, the state of gift certificate registration, and the state of product registration at the time of the operation. 24 and FIG. 25, the behavior (operation) after the operation of the mode switching button 211a is changed at the time of the operation. This is to explain that the state differs depending on the state of the operation of the clerk side and the state of the operation of the customer side. Specifically, FIG. 24 is an explanatory diagram illustrating various operations after the mode switching operation from the normal mode to the full self mode. FIG. 25 is an explanatory diagram illustrating various operations after the mode switching operation from the full self mode to the normal mode.

  In FIG. 24 (similarly in FIG. 25), “the clerk-side operation or the like alone state” is, for example, a state where the clerk-side operation is performed, the customer-side operation is not performed, and the customer is not detected. The “single state on customer side operation” is, for example, a state where there is no operation on the clerk side, there is an operation etc. on the customer side, and no customer is detected. The “independent state such as customer detection” is, for example, a state where there is no operation such as a clerk side, there is no operation such as a customer side, and there is a customer detection.

  The clerk side operation or the like means that the clerk side operation (see FIG. 2 and the like) is performed (for example, the operation of the clerk side display unit 210, the operation of the key operation unit (excluding the mode switching button 211a), and the clerk side scanner unit 212. Operation or the like).

  The operation on the customer side (for example, FIG. 2 and the like) means the operation on the customer side (for example, the operation on the customer side display unit 205, the operation on the customer side scanner unit 206, the operation on the card settlement unit 208, the operation on the change machine 209). Operation or the like).

  The member card or the like may be read by the clerk (the clerk-side scanner unit 212 or the like) or by the customer (the customer-side scanner unit 206 or the like). In addition, in the case of the full self mode, registration of a purchased product is generally performed on the customer side (the customer side scanner unit 206 and the like), but may also be performed on the clerk side (the clerk side scanner unit 212 and the like) ( Double scan mode).

  The “both-side operation state” in FIG. 24 (similarly in FIG. 25) is, for example, a state in which a clerk-side operation is performed, a customer-side operation is performed, and no customer is detected. The “customer detection state such as clerk side operation” is, for example, a state in which a clerk side operation is performed, a customer side operation is not performed, and a customer is detected. The “customer detection state such as customer side operation” is, for example, a state where there is no operation at the clerk side, there is an operation etc. at the customer side, and there is a customer detection state.

  For example, when the mode switching button 211a is operated in the normal mode, the POS terminal 20 operates as illustrated in FIG. 24 instead of operating as illustrated in FIG. Is also good. Also, when the mode switching button 211a is operated in the full self mode, the POS terminal 20 operates as shown in FIG. 25 instead of operating as shown in FIG. You may.

  The POS terminal 20 operates as shown in FIG. 19 when the mode switching button 211a is operated in the normal mode, and operates when the mode switching button 211a is operated in the full self mode. If there is, it may operate as shown in FIG. That is, when the mode switching button 211a is operated in the normal mode, the behavior (operation) after the operation of the mode switching button 211a is changed to the cash input state and the payment type selection state at the time of the operation. When the mode switch button 211a is operated in the full self mode, the state is changed according to the state of gift certificate registration, the state of merchandise registration, the state of customer information acquisition, and the state of customer detection. The behavior (operation) after the operation of the mode switching button 211a may be made different depending on the state of the operation of the clerk, the state of the operation of the customer, etc. at the time of the operation.

  The POS terminal 20 operates as shown in FIG. 24 when the mode switching button 211a is operated in the normal mode, and operates when the mode switching button 211a is operated in the full self mode. If there is, it may operate as shown in FIG. That is, when the mode switching button 211a is operated in the normal mode, the behavior (operation) after the operation of the mode switching button 211a is changed according to the state of the operation of the clerk at the time of the operation, the customer side, and the like. In the full self mode, when the mode switching button 211a is operated, the behavior (operation) after the operation of the mode switching button 211a is changed. The state may be different depending on the state of cash input, the state of payment type selection, the state of gift certificate registration, the state of merchandise registration, the state of customer information acquisition, and the state of customer detection.

  Meanwhile, in FIG. 19, there are a case where information is canceled (for example, a state of cash input alone, a state of product registration alone, etc.) and a case where information is taken over without being canceled (state of cash input product registration, state of cash input customer detection, etc.). However, the case where the information is canceled is basically the case where there is a high possibility that the information is unnecessary as compared with the case where the information is taken over.

  For example, a state in which cash is merely inserted (a state in which cash is input alone) is not high because there is no high possibility that the cash input is intended or the possibility that the payment information is actually used immediately in a transaction. In this state (only cash input state), payment information cancellation processing is executed to cancel the payment information. This is particularly true when the mode switching operation is originally performed in the initial state. In other words, if the mode switching operation is performed in a scene where it can be believed that there is no deposit and the product is not being registered (for example, a scene where there is no customer), if only the deposit information actually remains, the deposit information Because it is considered unlikely that the information will be taken over and used, the deposit is discharged and the deposit information is canceled. In addition, for example, a state in which a product is simply registered (a product registration alone state) is not likely to be intended by the product registration or is unlikely to be used immediately for a transaction in actuality of the product information. In the state (commodity registration only state), the merchandise information cancellation process is executed to cancel the merchandise information. This is particularly true when the mode switching operation is originally performed in the initial state. That is, when the mode switching operation is performed in a scene where there is no customer, if only the product information actually remains, it is unlikely that the product information is information that can be taken over and used. The product information has been canceled because it is possible.

  On the other hand, for example, a state in which cash is inserted and a product is registered (cash-input product registration state) is highly likely to be intended because two operations and the like are performed. In the product registration state), the payment information transfer process and the product information transfer process are executed, and the payment information and the product information are taken over.

  In FIG. 23, the case where the information is canceled and the case where the information is held without canceling are the same as in FIG.

  Similarly, in FIG. 24, there are a case where information is canceled (for example, a clerk-side operation alone state, a customer-side operation etc. alone state) and a case where information is taken over without being canceled (two-sided operation state etc.). Is basically a case where there is a high possibility that the information is unnecessary as compared with the case where the information is taken over.

  In other words, the state in which either the clerk side or the customer side is operated (the clerk side operation etc. alone state, the customer side operation etc. single state) is the state where both the clerk side and the customer side are performed (both side operation). State, etc.), the possibility that the state is the intended state or the possibility that the information is actually used immediately is not high. Therefore, in the state where either the clerk side or the customer side is operated (the clerk side operation etc. alone state, the customer side operation etc. single state), the information is canceled, and both the clerk side and the customer side are performed. In the state (two-sided operation state, etc.), information is taken over.

  In FIG. 25, the case where the information is canceled and the case where the information is held without canceling are the same as in FIG.

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

(Arrangement layout)
FIG. 26 is an example of an arrangement layout of the POS terminal 20. Specifically, FIG. 26A shows a configuration including four POS terminals 20 in the full self mode (hereinafter, this configuration is referred to as configuration A). Configuration A is a configuration that is relatively suitable for a less busy time zone.

  The customer who has completed the shopping at the counter goes to one of the four POS terminals 20 in the full self mode, registers the product by himself, and performs payment. In addition, the customer may select a POS terminal 20 (a vacant POS terminal 20 or the like) that performs processing (registration, settlement) according to the customer's own judgment, but the clerk (not shown in FIG. May be instructed to the customer who has finished. Alternatively, an attendant-only terminal (not shown) may be provided, and a customer who has completed shopping may be guided to the POS terminal 20 to be processed on the display screen of the terminal. In the case of the configuration A, as shown in FIG. 26A, four lines of accounting lines (flow lines) are formed.

  Note that a configuration including the plurality of POS terminals 20 (the configuration A and the configuration B described later) may be referred to as an “island”.

  FIG. 26B shows a configuration including two POS terminals 20 in the normal mode and two semi-self modes (accounting-only mode) (hereinafter, this configuration is referred to as configuration B). Configuration B is a configuration suitable for a relatively busy time zone. In the case of the configuration B, as shown in FIG. 26 (B), two accounting lines are formed (although there are two lanes), but the POS terminal 20 on the upstream side of each accounting line is in the normal mode, The POS terminal 20 on the downstream side of each accounting lead is in the semi-self mode (accounting-only mode).

  The customer who has completed shopping at the counter goes to one of the two POS terminals 20 in the normal mode, and the clerk registers the product. After the registration by the clerk, the registration information is transmitted to the POS terminal 20 in the semi-self mode (accounting-only mode), so that the customer himself makes the payment. The registration information is generally transmitted to the POS terminal 20 in the same lane semi-self mode (accounting only mode) so as not to disturb the illustrated accounting lead, but the other lane semi-self mode (accounting only mode). Can be transmitted to the POS terminal 20.

  Next, a general operation in the case where the registration information is transmitted to the POS terminal 20 in the same lane in the semi-self mode (accounting only mode) will be described.

(1) The POS terminal 20 in the normal mode (or the clerk of the device; the same applies to the following description) starts the product registration of a certain customer (customer 1) on the clerk side. After completing the merchandise registration of the customer 1, the POS terminal 20 in the normal mode transmits the registration information of the customer 1 to the other terminal, the POS terminal 20 in the semi-self mode (accounting only mode).
(2) The POS terminal 20 in the normal mode that has transmitted the registration information of the customer 1 starts registration of the merchandise of the next customer (customer 2) on the clerk side. The POS terminal 20 in the normal mode, when the customer 1 as the previous customer is still in the semi-self mode (accounting-only mode) after the completion of the product registration of the customer 2, (when the settlement of the customer 1 in another terminal is not completed) , The customer 2 of his / her own terminal performs the settlement of the customer 2. When the second customer (customer 3) appears during the checkout of customer 2, since the clerk is vacant, registration of the customer 3's product is started. That is, the POS terminal 20 in the normal mode can execute the checkout process for the customer 2 on the customer side and can execute the registration process for the customer 3 on the clerk side (the checkout of the customer 2 and the registration of the customer 3 are performed in parallel. Can be processed).
(3) The POS terminal 20 in the normal mode, when the customer 2 who is the former customer is still at the customer side of the own terminal after the completion of the product registration of the customer 3 (when the settlement of the customer 2 in the own terminal is not completed) ), The registration information of the customer 3 is transmitted to the POS terminal 20 in the semi-self mode (accounting only mode), which is another terminal.

  Subsequently, switching from the configuration A to the configuration B and switching from the configuration B to the configuration A will be described.

  There are two types of methods for switching from Configuration A to Configuration B (switching from Configuration B to Configuration A). One is a method (individual method) in which a plurality of POS terminals 20 (four in the example of the configuration A and the configuration B) constituting the "island" individually perform a mode switching operation. The other is a method of performing a mode switching operation on any one of the POS terminals 20 (one of four terminals in the example of the configuration A and the configuration B) constituting the “island”. This is a method (collective method) in which the mode switching of the other POS terminals 20 constituting the “island” is performed collectively by operation.

  FIG. 27 is an explanatory diagram illustrating mode switching. Specifically, FIG. 27A is an explanatory diagram illustrating mode switching and the like when switching from configuration A to configuration B. More specifically, the column (a) of FIG. 27A describes the individual method in switching from the configuration A to the configuration B described above. Column (b) of FIG. 27A is a description of the batch system in switching from configuration A to configuration B described above. FIG. 27B is an explanatory diagram illustrating mode switching and the like when switching from configuration B to configuration A. More specifically, column (c) of FIG. 27B describes the individual method in switching from configuration B to configuration A described above. Column (d) of FIG. 27B is a description of the batch system in switching from the configuration B to the configuration A described above.

  As shown in FIGS. 27 (A) and 27 (B), the collective method is more advantageous than the individual method because switching from configuration A to configuration B or from configuration B to configuration A requires less trouble.

  In order to implement the batch method, each POS terminal 20 stores information indicating how to switch modes when a switching operation is performed or when a switching instruction is received (or other information). Switching to an appropriate operation mode (the operation mode shown in the column (b) of FIG. 27A or the column (d) of FIG. 27A) according to the switching operation or the switching instruction by inquiring of the terminal). What should I do?

  Further, as shown outside the table of FIG. 27, the mode switching operation in the individual mode (the same applies to the batch mode) may be performed by a hardware key or a software key (described later). Further, as an individual method (the same applies to a collective method), each operation mode may be switched by a mode switching instruction from a monitoring terminal or a portable terminal of a clerk instead of or in addition to the mode switching operation.

  In the batch method, a specific POS terminal 20 (for example, a POS terminal 20 frequently used by a store manager or the like (a POS terminal 20 arranged at a certain place), a store manager, etc.) logs in instead of any of the POS terminals 20. POS terminal 20 or the like) may enable switching of the batch method. For example, when the switching button 211a is operated on a specific POS terminal 20, switching is performed in a batch mode, but when the switching button 211a is operated on a POS terminal 20 other than the specific POS terminal 20, May not be executed in the batch mode.

  In the batch mode, a dedicated button for the batch mode may be prepared (for example, a batch switching button 211b (see FIG. 3B)).

  Further, the operation using the batch switching button 211b may be effective in a specific POS terminal 20. For example, a batch switching button 211b is arranged on a specific POS terminal 20 (for example, a POS terminal 20 frequently used by a store manager or the like (a POS terminal 20 arranged at a certain place)) and a POS terminal other than the specific POS terminal 20 The batch switching button 211b may not be arranged on the terminal 20. Although the batch switching button 211b is arranged on all the POS terminals 20, a specific POS terminal 20 (for example, a POS to which a store manager or the like is logged in) is used. When the collective switching button 211b is operated on the terminal 20 or the like, the switching by the collective method is executed. However, when the collective switching button 211b is operated on the POS terminal 20 other than the specific POS terminal 20, May not be executed in the batch mode.Operation by the accounting-only mode switching button 211c (described later) may be performed. The same is true.

  Next, the individual switching method will be described. FIG. 27 is an explanatory diagram illustrating mode switching. Although the configuration A and the configuration B have been described above, the individual switching method described with reference to FIG. 27 is also applied to a case where the configuration is appropriately switched to a configuration other than the configurations A and B. For example, the present invention is also applied to a case where the configuration is switched to a configuration in which one POS terminal 20 in the normal mode and one POS terminal 20 in the semi-self (accounting-only mode) and two POS terminals 20 in the full-self mode.

  It has been described that the operation modes are sequentially switched every time the mode switching button 211a is operated on the assumption that the operation modes are two types (normal mode and full self mode). Even when the operation mode is present, each time the mode switching button 211a is operated, the operation mode may be sequentially switched to each operation mode, as in the case where the two types of operation modes exist. When there are three or more types of operation modes, a plurality of operations are required when switching to a target operation mode.

  FIG. 28 is an explanatory diagram illustrating mode switching. 28 illustrates an example in which three types of operation modes (normal mode, full self mode, and semi-self (accounting-only mode) are sequentially switched). In the case of 1), the mode is switched from “normal mode” → “full self mode” → “semi self (accounting only mode)”. For example, when the current operation mode is the normal mode, the mode is switched to semi self (accounting only mode). This requires two operations.

  If a plurality of mode switching operations are prepared, the number of operations when switching to the target operation mode is reduced. In the individual mode (2) shown in FIG. 28, when the mode switching operation 1 (for example, the operation of the switching button 211a in FIG. 3) is performed, the normal mode and the full self mode are sequentially switched, and the mode switching operation is performed. When 2 (for example, the operation of the accounting-only mode switching button 211c in FIG. 3) is performed, the mode is switched to “semi-self (accounting-only mode)”. The POS terminal 20 may switch the operation mode of each POS terminal 20 by a method using the individual method (2) instead of the individual method (1).

  As shown outside the table of FIG. 28, when the mode switching operation 1 is performed (the same applies when the mode switching operation 2 is performed), the current operation mode is “semi-self (accounting-only mode)”. If so, the operation mode (the “normal mode” or the “full self mode”) before switching to the “semi-self (accounting-only mode)” may be switched.

  Further, instead of the individual mode (1) or the individual mode (2), a number of mode switching buttons corresponding to each of the operation modes are prepared, and the mode is switched to the operation mode corresponding to the operated mode switching button. Good.

  The mode switching button 211a and the like for switching the operation mode are hardware keys, but the operation mode is switched by a software key displayed on a display unit (the clerk-side display unit 210 and the like) instead of or in addition to the hardware key. You may do so. That is, a software key corresponding to the switch button 211a may be displayed instead of or in addition to the switch button 211a, or a software key corresponding to the batch switch button 211b may be displayed instead of or in addition to the batch switch button 211b. Alternatively, a software key corresponding to the accounting-only mode switching button 211c may be displayed instead of or in addition to the accounting-only mode switching button 211c. The same applies to each button in the case of preparing a number of mode switching buttons corresponding to each of the operation modes.

  FIG. 29 is an explanatory diagram illustrating a bag receiver. FIG. 29A shows a state of the bag receiver which is suitable when the POS terminal 20 is in the full self mode. FIG. 29 (B) is an enlarged view of a part (bag receiving plate 300) of FIG. 29 (A). In FIG. 29A, the right side is the upstream side of the accounting wire, and the left side is the downstream side. The same applies to FIGS. 29C and 29D.

  In the full self mode, customers themselves pack bags for purchase. As shown in FIGS. 29 (A) and 29 (B), the person (customer) who packs the purchased product hangs a bag (shopping bag, carry-on bag) on the arm 301 standing upright from the bag receiving plate 300. And bag the purchased goods. In the case of the bag receiver, the arm 301 stands on the side of the person (customer) who packs the purchased product (that is, the customer side (see FIG. 2)). In addition, since the bag is on the downstream side, it is easy to pack purchased goods.

  FIG. 29C shows a state of the bag receiver which is suitable when the POS terminal 20 is in the normal mode. In the normal mode, basically, the sales clerk packs the purchased product (for example, every time a product is registered, the product is packed when the customer is checking out). As shown in FIG. 29 (C), the person (shop clerk) who packs the purchased merchandise puts the bag on the arm 302 standing upright from the side of the POS terminal 20 and packs the purchased merchandise. In the case of the bag receiver, the bag receiving plate 300 does not interfere, so that a person (shop clerk) who packs the purchased product is easy to put the bag, and the bag is on the downstream side, so that the purchased product is easily packed.

  FIG. 29D shows a state where the bag is not used. When the bag hook is not used, as shown in FIG. 29 (D), the bag receiving plate 300 rotates (rotates to the near side in the figure) so as to match the side surface of the housing, and the arm 302 It is folded on the side. In addition, a storage portion (dent, groove, etc.) for storing the arm portion 301 is provided at a position facing the arm portion 301 on the side surface of the case so that the bag receiving plate 300 is properly fitted to the side surface of the case of the POS terminal 20. Is also good.

  If necessary (for example, when the POS terminal 20 is switched from another operation mode to the full self-mode), the clerk may change the bag receiving plate 300 stored as shown in FIG. Rotate to the position (A). Note that, by providing a drive unit that controls the rotation of the bag receiving plate 300, the bag receiving plate 300 may be automatically rotated (not manually by a clerk). When switching from the full self mode to another operation mode, the reverse operation may be automatically performed.

  Also, the clerk may, if necessary (for example, when the POS terminal 20 is switched from another operation mode to the normal mode), move the folded arm portion 302 as shown in FIG. ). Note that the arm 302 may be automatically raised by providing a drive unit that controls the rising of the arm 302. When switching from the normal mode to another operation mode, the reverse operation may be automatically performed.

  In the semi-self (accounting-only mode), the state shown in FIG. 29A or the state shown in FIG. 29D is suitable. For example, after the product is registered by the store clerk, when the customer moves to the terminal, the bagging of the purchased product is already completed (for example, in the state of the bag receiving device in FIG. The state shown in FIG. 29 (D) is suitable for the case where bags are packed at the time of registration. On the other hand, when the customer moves to the terminal after the product registration by the clerk, the bagging of the purchased product is not completed (in the case of moving to the terminal with the shopping basket), FIG. The state shown in (A) is suitable.

  As described above, the embodiment has been described with reference to the drawings. However, according to the embodiment, when the mode switching operation is performed, the POS terminal 20 is suitably operated according to the situation (state) at the time of the operation. be able to.

  For example, as shown in FIGS. 19 and 23, when the mode switching operation is performed, the POS terminal 20 operates at the time of the operation, the state of cash input, the state of selection of the settlement type, the state of the gift certificate, and the like. It operates suitably according to the state of class registration, the state of product registration, the state of customer information acquisition, and the state of customer detection.

  Further, for example, as shown in FIGS. 24 and 25, when the mode switching operation is performed, the POS terminal 20 operates at the time of the operation, the state of the clerk side operation, the state of the customer side operation, and the like. And it operates suitably according to the state of customer detection.

  Alternatively, as shown in FIGS. 19, 23, 24, and 25, when the mode switching operation is performed, the POS terminal 20 replaces or adds to the mode switching process according to the situation at the time of the operation. , Other suitable processing different from the mode switching processing (for example, payment information cancellation processing, payment information transfer processing, payment type information cancellation processing, payment type information transfer processing, gift certificate information cancellation processing, gift certificate information Takeover processing, product information cancellation processing, product information takeover processing, customer information cancellation processing, customer information takeover processing).

  Alternatively, if any information remains (if not the initial state) when the mode switching operation is performed, the POS terminal 20 determines whether the state is the intended state. , The operation after the operation is different.

  For example, in a state where only cash has been inserted (only cash input state) or a state where only goods have been registered (only product registration state), it is determined that the possibility that the state is intended is not high. Although the information is canceled, when cash is inserted and the product is registered (cash-in product registration status), it is determined that there is a high possibility that the status is the intended one, and the information is determined. It has not been canceled (see FIGS. 19 and 23).

  Also, for example, when either the clerk side or the customer side is being operated (independent state such as clerk side operation, independent state such as customer side operation), there is a high possibility that the state is intended. Although it is determined that there is no information and the information has been canceled, when both the clerk and the customer are in a state (such as a double-sided operation state), it is determined that there is a high possibility that the state is intended and the information is determined. Has not been canceled (see FIGS. 24 and 25).

  Note that the above embodiment is an example, and the specific configuration is not limited to the above embodiment, and includes a design and the like within a range not departing from the gist of the invention.

For example, in the above-described embodiment, when a plurality of pieces of information exist when a mode switching operation is performed, and when the information is not canceled, all of the plurality of pieces of existing information are prevented from being canceled. A part of the plurality of pieces of information may be canceled, and some of the pieces of information may not be canceled.
For example, in the above-described embodiment, when cash is inserted and a product is registered (cash-inserted product registration state), both the deposit information and the product information are taken over (see FIG. 19) or held. (Refer to FIG. 23), the payment information is canceled, and the merchandise information is taken over (or may be retained).

  In other words, when the mode switching operation is performed, one cancellation process (for example, the payment information cancellation process in the above example) and one takeover process (for example, the product information takeover process in the above example) shown in FIG. May be executed.

  In the above-described embodiment, the payment information is always canceled when the state at the time of the mode switching operation is the cash input alone state (see FIGS. 19 and 23). The processing may be varied depending on the amount of money to be inserted, the number of inserted money, bills or coins, etc.).

  For example, when the total input amount is less than the predetermined amount, it is determined that the input is not likely to be intended, and the input information is canceled while the input total amount is equal to or more than the predetermined amount. In this case, it may be determined that the input is highly likely to be intended, and the deposit information may be taken over or held.

  Further, for example, if the total number of coins (coins, bills) is less than a predetermined number, it is determined that the possibility of the insertion is not high, and the payment information is canceled while the total number of coins is canceled. Is greater than or equal to the predetermined number, it is determined that the input is likely to be intended, and the deposit information may be taken over or held.

  Also, for example, when a coin has been inserted, it is determined that the possibility of the insertion is not high, and the payment information is canceled. It may be determined that there is a high possibility that the input is intended, and the deposit information may be taken over or held.

  Also, for example, when only coins or only banknotes have been inserted, regardless of the total number of insertions above, it is determined that the possibility that the insertion is intended is not high, and the payment information is canceled. In the case where coins and bills have been inserted, it is determined that there is a high possibility that the insertion is intended, and the deposit information may be taken over or held.

  In the above-described embodiment, the gift certificate information is always canceled when the mode switching operation is performed in the gift certificate registration alone state (see FIGS. 19 and 23). The processing may be changed according to the registration status of the class (amount, number, type, etc.).

  For example, if the total amount of gift certificates (the total amount of registered gift certificates) is less than a predetermined amount, it is determined that the registration is not likely to be intended, and the gift certificate information On the other hand, if the total value of the gift certificates is equal to or more than the predetermined amount, it is determined that the registration is likely to be intended, and the gift certificate information should be taken over or retained. It may be.

  For example, if the total number of gift certificates (the total number of registered gift certificates) is less than a predetermined number, it is determined that the registration is not likely to be intended, and While the information is canceled, if the total number of gift certificates is equal to or greater than a predetermined number, it is determined that the registration is likely to be intended, and the gift certificate information is taken over or retained You may do so.

  Also, for example, if only a single type of gift certificate is registered (for example, two A gift certificates) regardless of the total number of gift certificates, the registration may be intended. It is judged that the gift certificate is not high, and the gift certificate information is canceled. On the other hand, when a plurality of gift certificates are registered (for example, one gift certificate A and one gift certificate B), Alternatively, it may be determined that the registration is highly likely to be intended, and the gift certificate information may be taken over or retained.

  Further, in the above embodiment, when the state at the time of the mode switching operation is the product registration alone state, the product information is always canceled (see FIGS. 19 and 23), but the registration status of the product (see FIGS. 19 and 23). The processing may be made different depending on the amount of money, points, etc.).

  For example, if the total price of the product (the total price of the registered products) is less than a predetermined amount, it is determined that the registration is not likely to be intended, and the product information is canceled. If the total product price is equal to or more than the predetermined price, it is determined that the registration is highly likely to be intended, and the product information may be taken over or held.

  Also, for example, when the total number of products (the total number of registered products) is less than a predetermined number, it is determined that the registration is not likely to be intended, and the product information is canceled. On the other hand, when the total number of items is equal to or more than the predetermined number, it is determined that the registration is highly likely to be intended, and the item information may be taken over or held.

  Further, in the above embodiment, the operation after the mode switching operation is made different depending on the state at the time of the mode switching operation, but the operation after the mode switching operation is made different in consideration of the time during which the state is continued. You may. That is, the operation may be made different depending on the lapse of time from each state. As an example, when the state at the time of the mode switching operation is the cash input alone state, the operation may be changed according to the elapsed time from the cash input.

  For example, the POS terminal 20 stores the time at which the cash is inserted, and, when the state at the time of the mode switching operation is the single cash input state, the cash input time (over a plurality of times). If the elapsed time from the last cash input time is longer than a predetermined time, the payment information is canceled, while if the elapsed time from the cash input time is less than the predetermined time, The payment information may be taken over or held. Note that the processing may be made different by combining the above-described cash insertion status (input amount, number of inserted coins, bills or coins, etc.) and the elapsed time from the cash input time. Alternatively, the elapsed time from the cash input time may be regarded as one of the cash input situations.

  Further, for example, the POS terminal 20 stores the time at which the product is registered, and stores the product registration time (a plurality of times) when the mode switching operation is performed in a single product registration state. If the elapsed time from the last product registration time is longer than a predetermined time, the relevant product information is canceled, while if the elapsed time from the cash input time is less than the predetermined time, May carry over or hold the product information. In addition, the processing may be made different by combining the above-described registration status of the product (e.g., amount, score, etc.) and the elapsed time from the product registration time. Alternatively, the elapsed time from the product registration time may be regarded as one of the registration statuses of the product.

  Further, in the above-described embodiment, when the mode switching button 211a is operated, a process corresponding to the state when the mode switching operation is performed is executed (the operation according to the state when the mode switching operation is performed). However, what kind of processing is executed (what kind of operation is performed) before the processing is actually executed may be notified. For example, in the case where an operation is performed after the mode switching operation, before the operation is actually performed, an indication that the operation is to be performed is displayed, and an OK button for asking the clerk to reject the operation is performed. And an NG button may be displayed, and the operation may not be performed when the NG button is operated, and the operation may be performed when the OK button is operated. The same applies to the case where the batch switching button 211b or the accounting-only mode switching button 211c is operated. In a mode using software keys (a software key corresponding to the switching button 211a, a software key corresponding to the batch switching button 211b, and a software key corresponding to the accounting-only mode switching button 211c), the mode switching button of the software key is operated. The same applies to the case.

  In an aspect in which the operation mode is switched by a software key (an aspect having a software key instead of or in addition to a hardware key), the operation mode is switched in association with the software key (for example, superimposed on the software key or superimposed on the software key). Or around the display position of the software key), when the mode switching operation is performed by the software key (when the mode switching button 211a is provided, the mode switching operation is performed by the mode switching button 211a). May be displayed), information for notifying what kind of processing is actually executed (what kind of operation will be performed) may be displayed.

  Further, after the mode switching operation (operation of the hardware key, software key, etc.), a plurality of types of operation modes (individual operation modes, configuration A, configuration B, etc., operation modes relating to the entire "island") can be selected by the clerk. ) May be displayed (for example, displayed on the clerk-side display unit 210, displayed on a mobile terminal such as a smartphone or a tablet terminal used by the clerk), and switched to the operation mode selected by the clerk.

  In addition, instead of or in addition to when the mode switching operation (operation of the hardware key, the software key, etc.) is performed (after the mode switching operation), when the mode switching operation is not performed, the clerk selects as described above. A plurality of types of operation modes may be displayed in a possible manner. For example, when the store clerk operates (presses) the image GA02, the image GA03, or the like in FIG. 9A, a plurality of types of operation modes may be displayed in a manner selectable by the store clerk. That is, when the image GA02 of FIG. 9A is operated, the operation mode of the switching destination (switching candidate) of the POS terminal 20-2 corresponding to the image GA02, and the POS terminal 20-2 corresponding to the image GA02. The configuration (configuration A, configuration B) and the like of the switching destination of the island to which may belong may be displayed so that the clerk can select it. Also, for example, a dedicated area may be provided on the registration screen, and a plurality of types of operation modes may be displayed in the dedicated area basically always in a manner that can be selected by a clerk as described above.

  Alternatively, in addition to or in addition to the above, information regarding switching of the “island” may be reported. For example, depending on the congestion situation in the store, for example, the POS terminal 20 (specific POS terminal 20 or all POS terminals in the store), the monitoring terminal, and the portable terminal used by the clerk are referred to as “islands”. A notification urging the mode switching may be made. The store clerk may check and determine the congestion status in the store, or may automatically determine using a camera in the store (a camera installed on the ceiling or the POS terminal 20), or The determination may be made automatically based on the operating status of the 20. In addition, instead of or in addition to the congestion state in the store, information about switching of “island” may be notified according to a predetermined schedule. For example, in the case of a store where the number of customers starts to decrease after 20:00, a schedule is set at 20:00 to notify the user of switching from the configuration B to the configuration A, and the configuration is changed from the configuration B according to the schedule (at 20:00). A notification for urging the user to switch to A may be made.

  In addition, instead of or in addition to the above-described notification, a setting may be made so that the “island” mode can be switched according to a predetermined schedule. For example, since the number of customers is large until 20:00, the schedule may be set to operate in the configuration B, and to switch to the operation in the configuration A around 20:00 when the number of customers starts to decrease.

  If it is determined that the switching key for normally performing only the mode switching of the own device is before or after the scheduled switching time (for example, 19:50 to 20:10), the switching of the own device is performed. Alternatively, it may be displayed so that the user can select whether to switch “island” or the like. That is, there is a case where only one device can be switched by a certain mode switching operation (operation of a hardware key, a software key, and the like), and a case where switching of the own device or “island” can be performed. You may.

  Further, in the mode in which the operation mode is switched by the software key, instead of or in addition to information for notifying what kind of processing is actually executed (what kind of operation is performed) in association with the software key, Information for notifying the various states described above (the various states shown in FIGS. 19, 23, 24, 25, etc.) may be displayed. Note that information (information related to the selected payment type, acquired customer information, registered gift certificate information, and the like) displayed in the tab area T1 may be displayed as information for notifying various states.

  In addition, the POS terminal 20 performs a mode switching operation by using a button on an external device that can be connected to the POS terminal 20 by wire or wirelessly instead of or in addition to the hardware key (mode switching button 211a) or the software key described above. (A hardware key provided on the external device or a software key displayed on the screen of the external device) can be accepted, and if an operation of a button on the external device is accepted, The same control as when the operation of the switching button 211a is received may be performed.

  Although a part has already been described, when the POS terminal 20 receives a mode switching instruction (mode switching instruction) from another terminal (for example, a mobile terminal such as a smartphone or a tablet terminal used by a clerk), The same control as when the operation of the mode switching button 211a is received may be performed. As described above, in the mode of receiving a mode switching instruction from another terminal, the POS terminal 20 itself may have mode switching means (hardware key, software key). The mode switching means may not be provided.

  Note that a mode switching operation (including a mode switching instruction from another terminal) may be performed only when the user is a specific clerk (according to the authority of the operator). For example, when a store manager or the like logs in to the POS terminal 20, the mode switching operation is enabled (specifically, control is performed as shown in FIGS. 19, 23, 24, and 25), and a part-time job or the like is logged in. At times, the mode switching operation may be invalidated (an error or the like may be unconditionally made regardless of the state at the time of the mode switching operation).

  In the above embodiment, when the subtotal key is operated, the POS terminal 20-1 displays the small screen SG02 superimposed on the registration screen (FIG. 13A). When the subtotal key is operated, 1 may display a small planning surface for displaying information and the like displayed on the small screen SG02 instead of (switching) the registration screen.

  In the above-described embodiment, the POS terminal 20 includes one printing unit 213 that can freely change the direction from the clerk to the customer and from the customer to the clerk (see FIGS. 2 to 4). Instead of one printing unit 213, two printing units (a printing unit fixedly directed to the clerk side and a printing unit fixedly directed to the customer side) may be provided.

  In the above embodiment, when transmitting the registration information to another terminal, the clerk specifies (selects) the terminal of the transmission destination (destination) of the registration information. May specify that the registration information is to be transmitted without specifying the destination terminal. That is, only the transmission button may be arranged. In a mode in which the clerk only specifies that the registration information is to be transmitted without specifying the transmission destination terminal, the transmitting terminal selects one terminal to be the destination according to a predetermined priority and registers the selected terminal. Submit information.

  For example, when the POS terminal 20-1 transmits the registration information from the POS terminal 20-1 to another terminal (the POS terminal 20-2, the POS terminal 20-3), the POS terminal 20-3 in the full self mode is normally used. It may be higher than the POS terminal 20-2 in the mode (the registration information may be preferentially transmitted to the POS terminal 20-3 in the full self mode).

Hereinafter, supplementary notes 1 to 10 are disclosed.
(Appendix 1)
A sales data processing device operable in a plurality of operation modes,
Instruction receiving means for receiving an operation mode switching instruction (for example, a mode switching operation using a mode switching button 211a or a software key, a mode switching command, etc.) for switching the operation mode of the own device;
Control means for controlling the own device,
The control means includes:
If the state of the own apparatus when the operation mode switching instruction is issued is an initial state (for example, a state in which processing is not in progress), the operation mode switching processing for switching the operation mode of the own apparatus (see FIG. 20) Mode switching processing, etc.)
If the state of the own device when the operation mode switching instruction is issued is not the initial state, the operation mode switching processing is different from the operation mode switching processing instead of or in addition to the operation mode switching processing.
