As shown in FIG. 3 and 4, the same reference numerals are given to the same parts.

A configuration example of the POS terminal 20 shown in FIG. 4 will be described below 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 store clerk-side display unit 210, A key operation unit 211 , a store clerk side scanner unit 212 , a printing unit 213 , an audio output unit 214 , and a communication unit 215 are provided. They can communicate with each other via a bus. 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 programs stored in the ROM 202 .
The ROM 202 is a read-only memory, and stores various information used by the CPU 201 including programs.

A RAM 203 is a read/write memory and stores various information. For example, the RAM 203 stores information acquired from the outside (for example, a product master acquired from the store controller 10), information generated during processing (for example, registration information (registration data) generated in registration processing for registering products, (settlement information, etc. generated in settlement processing for settlement (settlement) of products).

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

The customer-side display unit 205 is a touch display for customers, which displays various information to the customer and receives various inputs from the customer.
A customer-side scanner unit 206 is a scanner unit for customers, and optically reads various kinds of information. For example, the customer-side scanner unit 206 optically scans barcodes (product codes, etc.) attached to products and codes (barcodes, two-dimensional codes, etc.) printed on accounting tickets (registered trademark). read. In addition to the above, the customer-side scanner unit 206 scans codes (bar codes, 2 dimension code, etc.) may be read.

The customer-side scanner unit 206 is used when the customer registers the product, but the customer may register the product by another method. For example, when a preset key corresponding to a product (a button for ordering 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 (credit cards, prepaid cards such as transportation cards, point cards, etc.). The card settlement unit 208 includes a card recognition unit (reading unit), display unit, and operation unit. The card recognition unit magnetically or electrically reads information on various cards. The read information is used for settlement (settlement) of purchased products. In addition, when using the recognized information for the payment (settlement) of the purchased product this time (that is, in the case of credit payment by credit card, in the case of prepaid card payment by prepaid card, the card recognition part will use (consumption), etc.), in addition to cases where the recognized information is not used for the payment (settlement) of the purchased product (for example, in the case of awarding benefits by presenting a credit card, in the case of awarding points to a point card) etc.) may also recognize various cards. Note that the card settlement unit 208 of this embodiment includes a card recognition unit (reading unit), a display unit, and an operation unit, but the card settlement unit 208 may include at least a card recognition unit. Further, the card recognition unit of this embodiment corresponds to a contact type card (IC card, magnetic card). may correspond to

The change dispenser 209 (cash settlement unit) is a settlement mechanism using cash, and has an insertion port for banknotes and coins and a discharge port for banknotes and coins. The amount of change, which is the difference, is calculated, and the change is discharged from the discharge port. The change dispenser 209 is directed toward the customer and is operated by the customer. Note that when banknotes or coins are inserted into the slot, they are detected by a sensor (detection of insertion, detection of the number of coins by denomination, etc.).

The clerk-side display unit 210 is a touch display for the clerk, and displays various information to the clerk and receives various inputs from the clerk.
The key operation unit 211 is composed of various keys (hardware keys, buttons) and receives various inputs from the store clerk.
The clerk-side scanner unit 212 is a scanner unit for the clerk, and optically reads various kinds of 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 clerk's name tag. In addition to the above, the clerk-side scanner unit 212 may read codes printed on checkout tickets, coupons, and codes printed on various cards.

Note that the clerk-side scanner unit 212 is used when the clerk registers products, but the clerk may register the products by other methods. For example, if a key corresponding to a product (for example, a key corresponding to a sports newspaper) is arranged in the key operation unit 211, the clerk can operate (press) the key to register the product. good. Further, 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, accounting coupons, etc.). The printing unit 213 can be rotatably changed from the clerk side to the customer side and from the customer side to the clerk side (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, etc.) based on, for example, switching of operation modes (details will be described later). Note that whether the orientation of the printing unit 213 is correct or incorrect may be detected by a sensor or the like. Note that the switching of the operation mode is also referred to as the operation mode transition.

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 other terminals (other POS terminals 20, store controllers 10).

(Outline of each operation mode)
Next, operation modes of the POS terminal 20 will be described. The POS terminal 20 has multiple operating modes. Specifically, the POS terminal 20 has at least three types of operation modes (normal mode, full-self mode, semi-self mode).

The operation mode described above is the operation mode during normal work (operation mode related to registration processing and settlement processing). Maintenance mode for maintenance work and training mode for new employees are not included.

In addition, in the following description, the mode in which the POS terminal 20 executes the registration process is the registration mode, and the settlement process is executed as a different approach from the classification of the operation modes (normal mode, full-self mode, semi-self mode) described above. This mode is sometimes called accounting mode.

5 and 6 are diagrams for explaining the outline of the operation modes of the POS terminal 20. FIG. FIG. 5 is a diagram for explaining the outline of the normal mode. FIG. 5(A) is a schematic diagram showing the flow of processing (registration processing, settlement processing) and actions of people (staff, customers) in the normal mode, and FIG. 5(B) shows the operation of the POS terminal 20 in the normal mode. 2 is a flowchart showing the basic flow of FIG. 6 is a diagram for explaining the outline of the full-self mode. FIG. 6(A) is a schematic diagram showing the flow of processing (registration processing, payment processing) and the operation of a person (customer) in the full self mode, and FIG. 6(B) is the operation of the POS terminal 20 in the full self mode. 2 is a flowchart showing the basic flow of

(normal mode)
The normal mode, as shown in FIG. 5A, is an operation mode in which the store clerk executes the registration process and the customer executes the settlement process. That is, as shown in FIG. 5(B), the POS terminal 20 in the normal mode is in the registration mode on the clerk side and in the checkout mode on the customer side. In other words, the POS terminal 20 in the normal mode operates in the registration accounting mode from the registration process to the settlement process as a whole.

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

When the store clerk completes the registration process, the customer confirms the total amount of purchased commodities on the store clerk side display unit 210, inserts money (cash) into the change dispenser 209, or operates the card payment unit 208 to make a payment. (Lower part of FIG. 5(A)). In other words, the POS terminal 20 executes settlement processing according to customer's operation (insertion of cash into the change machine 209, operation of the card payment unit 208) (lower part of FIG. 5A).

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

The customer may wait until the store clerk completes the registration process (until the total amount is determined), but may insert cash into the change dispenser 209 before the registration process is completed. That is, the POS terminal 20 can accept payment during the registration process (upper part of FIG. 5A).

Also, the customer may select a payment method (also referred to as payment type, settlement method, or settlement type) before completing the registration process. In other words, the POS terminal 20 can accept the selection of the payment method during the registration process (details will be described later).

In addition, the salesclerk may wait until the customer completes the payment (until the customer obtains change or a receipt), or may register the next customer's purchased product. In other words, the POS terminal 20 can register the purchased product of the next customer during the checkout process (lower part of FIG. 5A). Also, the clerk may be absent during the payment by the customer (lower part of FIG. 5(A)). In other words, the reception of the customer may be finished during the payment of the customer.

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

In the normal mode, as described above, the store clerk executes the registration process, and the customer of the own terminal executes the settlement process using the registration information generated in the registration process (see FIG. 5). In addition, the store clerk executes registration processing, and transmits the registration information generated in the registration processing to another terminal (other terminal capable of executing settlement processing, for example, another POS terminal 20) (via LAN 11 , directly to another terminal, or to another terminal via the store controller 10 or a monitoring terminal (not shown); code, two-dimensional code, etc.), printing it on a medium, and issuing it as an accounting ticket. In other words, the POS terminal 20 in the normal mode has a function of registering products on its own terminal and paying for it on its own terminal, as well as a function for registering products on its own terminal and paying for it on another terminal.

The above-described function of registering products on one's own terminal and making payment on another terminal is the 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 products on its own terminal and making payments on other terminals. Specifically, the POS terminal 20 in semi-self mode (registration-only mode) executes registration processing on the clerk side, and transmits registration information generated in the registration processing to other terminals (or generates registration information in the registration processing). The registered information, etc. obtained from the registration is coded, printed on a medium, and issued as an accounting ticket). The POS terminal 20 in semi-self mode (accounting only mode) has a function of paying for products registered on other terminals. Specifically, the POS terminal 20 in semi-self mode (accounting-only mode) receives the registration information transmitted from the POS terminal 20 in semi-self mode (registration-only mode) (or receives the registration information from the POS terminal 20 in semi-self mode (registration-only mode). The terminal 20 reads the issued accounting ticket) and executes settlement processing.

Note that the POS terminal 20 in normal mode has a function of registering a product on its own terminal and paying for it on another terminal, like the POS terminal 20 in semi-self mode (registration-only mode). The POS terminal 20 in normal mode may also have a function of paying for products registered on another terminal, like the POS terminal 20 in semi-self mode (accounting mode). That is, the POS terminal 20 in full-self mode and the POS terminal 20 in normal mode receive registration information from other terminals (the POS terminal 20 in semi-self mode (registration-only mode), the POS terminal 20 in normal mode, etc.). reading the accounting ticket) and executing the settlement process.

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

In the case of the full-self mode, the customer registers his/her purchased product on the customer side (customer side scanner section 206, customer side display section 205). In other words, the POS terminal 20 executes the registration process of the purchased product according to the customer's operation (scanning by the customer-side scanner unit 206, touching the customer-side display unit 205) (upper part of FIG. 6A).

When the registration process is completed, the customer confirms the total amount of purchased products on the customer-side display unit 205, inserts cash into the change machine 209, or operates the card settlement unit 208 to settle the account (Fig. 6 (A) ) below). In other words, the POS terminal 20 executes settlement processing according to customer's operation (insertion of cash into the change dispenser 209, operation of the card payment unit 208) (lower part of FIG. 6A).

That is, in the full-self mode, as shown in FIG. 6B, the customer scans the product (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 account is settled by, for example, the change machine 209 (step S50), and processing is performed. is completed. The registration completion key related to step S40 is an operation key for completing the registration process, and may also be called a registration completion button, subtotal key, subtotal button, checkout key, checkout button, or the like.

In the full-self mode, as described above, the customer side executes both the registration process and the settlement process, but this does not mean that the store clerk cannot do anything. That is, even when the 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 products. Is possible. A state (operation mode) in which registration processing is being performed on both the store clerk side and the customer side may be referred to as a double scan mode.

(Notification of operation mode)
Each POS terminal 20 may report its current operating mode. For example, each POS terminal 20 may display the current operation mode of its own terminal on the salesclerk side display section 210 . Specifically, each POS terminal 20 displays a screen having an operation mode display field of its own terminal on the clerk side display section 210, and displays the current operation mode of its own terminal in the operation mode display field on the screen. may In addition, each POS terminal 20 displays a screen on which an image corresponding to each operation mode (for example, a button-like image) is arranged on the clerk-side display unit 210, and the current operation mode of the own terminal is displayed on the screen. The image to be displayed may be displayed in a display manner different from that of the image that does not correspond to the current operation mode (for example, a display manner that is more conspicuous than the display manner 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 conspicuous display mode than the full self mode image, and the own terminal When the current operation mode is the full self mode, the full self mode image may be displayed in a more conspicuous display manner than the normal mode image. Each POS terminal 20 may similarly display the current operation mode of its own terminal on the customer side display section 205 as well.

Also, each POS terminal 20 may notify the current operation mode of another terminal instead of or in addition to the current operation mode of its own terminal. In other words, each POS terminal 20 may mutually recognize the current operation mode of the other terminal and notify the current operation mode of the other terminal. An example of a method in which each POS terminal 20 mutually recognizes the current operation mode of another terminal is that each POS terminal 20 notifies the other terminal of the operation mode after transition (latest operation mode) after the transition of the operation mode. or directly notify the other terminal via the store controller 10 or a monitoring terminal (not shown). Also, 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 its own current operation mode (operation mode, processing status, etc.). For example, each POS terminal 20 displays a predetermined message (see, for example, FIG. 7A) on the customer-side display section 205 when its current operation mode is the full self mode, for example, when it is on standby. may be displayed. Also, the POS terminal 20 may report information according to the current operation mode of the other terminal in place of or in addition to the information according to the current operation mode of its own terminal.

(Operation mode switching (transition))
Next, the operation mode transition of the POS terminal 20 will be described. The operation mode of the POS terminal 20 is switched (the operation mode is switched) according to an explicit mode switching operation (also referred to as a mode switching operation) by the store clerk. Specifically, the operation mode is switched according to the operation of the mode switching button 211a (see FIG. 3B) arranged at the topmost and rightmost end of the key operation unit 211. FIG.

Since the mode switching button 211a is arranged at the corner of the key operation unit 211, it is possible to reduce operation errors when switching the operation mode and to easily switch the operation mode. In other words, when the mode switching button 211a exists at the corner of the key operating unit 211, for example, compared to the case where the mode switching button 211a exists near the center of the key operating unit 211, for example, the mode switching button 211a to be operated Since the number of adjacent buttons is small, it is difficult to make an operation error such as hastily operating another button, and since the position of the mode switching button 211a to be operated can be specified instantly, the mode switching operation can be performed without stress. It can be performed.

Furthermore, since the mode switching button 211a is arranged at the corner of the upper right end (uppermost and rightmost end) of the key operation unit 211, the mode switching operation can be performed not only when the store clerk is on the store clerk's side but also when the customer is on the customer's side. be able to In other words, a store clerk on the customer's side usually cannot see each button of the key operation unit 211, but as for the mode switching button 211a existing at the upper right end of the key operation unit 211, the customer reaches out and gropes. Since the mode switching button 211a to be operated can be easily recognized only by (hand feel), the clerk on 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 switching button 211a is located at a position that can be recognized only by fumbling (a position that can be recognized relatively easily), the mode switching button 211a can be changed. The switching button 211 a may be arranged at a position other than the upper right corner of the key operation unit 211 . Instead of or in addition to arranging the mode switching button 211a at a position that can be recognized only by fumbling (for example, the upper right corner), the mode switching button 211a can be distinguished from other buttons even from the customer's side. , the mode switching button 211a may be formed. For example, the size of the mode switching button 211a may be made different from the size of the other buttons, or the shape of the mode switching button 211a may be made different from the shape of the other buttons to the extent that they can be distinguished by feeling. Alternatively, the height of the mode switching button 211a may be different from the height of the other buttons (for example, the mode switching button 211a may protrude more than the other buttons, or ), the feel of all or part of the surface of the mode switching button 211a (the surface touched by the hand) may be different from that of the other buttons (for example, only the surface of the mode switching button 211a may be rough or rough). A touch may be used, or projections or depressions may be provided only on the surface of the mode switching button 211a).

In the present embodiment, the mode switching button 211a is arranged in the key operating section 211 in consideration of various advantages as described above. Alternatively, in addition, a mode switching button (not shown) may be arranged on the screen displayed on the clerk-side display unit 210 .

Also, the POS terminal 20 can switch the operation mode without an explicit mode switching operation. For example, the POS terminal 20 has time-related conditions such as elapsed time (e.g., elapsed time since the last operation) and predetermined time (schedule); The operation mode is switched based on conditions related to transmission and reception of information such as a mode switching instruction (mode switching instruction).

It should be noted that whether the POS terminal 20 switches its own operating mode, regardless of whether the clerk explicitly switches the mode or not. A later operation mode (latest operation mode) may be notified to other terminals.

In the following description, it is assumed that the POS terminals 20-1 and 20-2 are in normal mode. It is also assumed that the POS terminal 20-3 is in full self mode. Also, in the following description, it is assumed that the POS terminal 20 switches its operation mode each time the mode switching button 211a is operated (pressed). However, in the following description, the description of the semi-self mode will be omitted for the sake of convenience. Therefore, basically every time the mode switching button 211a is operated, the operation mode is switched from the normal mode to the full self mode, and then 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)
7 and 8 are display examples of the POS terminal 20 in full self mode. Specifically, FIGS. 7(A), 7(B), and 8(A) to 8(F) show the display on the customer-side display section 205 of the POS terminal 20-3 in full self mode. This is an example.

FIG. 7A shows the display contents of the registration start screen before starting the registration process. 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 the registration screen in which two items of products (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 the registration screen in which no products have been registered yet. For the sake of convenience, FIG. 7B shows the registration screen after the products (tea, daifuku mochi) have already been registered.

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

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 preset keys for vegetables (see FIG. 9).

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

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

FIG. 8(C) shows the display contents of the settlement screen (deposit screen) displayed when the deposit amount is determined. For example, the POS terminal 20-3 displays a deposit screen as shown in FIG. 8(C) when cash (deposit) exceeding the payment amount (purchase amount) is inserted.

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

FIG. 8(E) shows the display contents of the settlement screen (receipt screen) displayed when the change is removed. For example, the POS terminal 20-3 displays a receipt screen as shown in FIG. Note that the POS terminal 20 may be provided with a sensor such as a photo sensor near the outlet, and may determine that the change has been removed when the sensor recognizes an object (assuming the customer's hand). FIG. 8F shows a pause screen displayed in the pause mode (hibernate state).

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. FIG. The POS terminal 20 may have a sensor capable of recognizing that the receipt has been removed from the issuing port. Further, when no change is generated, the change screen (FIG. 8(D)) may not be displayed, and the deposit screen (FIG. 8(C)) may transition to the receipt screen (FIG. 8(E)). .

(Display example of POS terminal 20 in normal mode)
9 to 14 are display examples of the POS terminal 20 in normal mode. Specifically, FIGS. 9A, 10A, 11A, 12A, 13A, and 14A show the POS terminal in normal mode. 20-1 is an example of display on the clerk's side display unit 210. FIG. 9(B), 10(B), 11(B), 12(B), 13(B), and 14(B) show the customer status of the POS terminal 20-1 in the normal mode. It is a display example on the side display unit 205 .

FIG. 9A shows the content displayed on the registration screen in the initial state on the store clerk's display unit 210 . Unless otherwise specified, the initial state in the following description is a state in which no processing has progressed, for example, a state in which no products have been registered yet, and no payment (settlement) has been made yet. In a state (such as when a payment method has not been selected, cash has not been inserted, and coupons have not been registered), and in a state in which nothing has been done about the customer (such as when the membership card has not been read, etc.) be.

In FIG. 9A, a tab area T1 on the upper right of the screen is a tab corresponding to each display content (display screen). The POS terminal 20-1 can interrupt the registration processing of the customer (the reason for the interruption is to return to the store to add the purchased product, etc.) and register the next customer. In other words, the POS terminal 20-1 displays a new registration screen for the next customer while holding (storing) the display contents (registration contents) of the registration screen for the customer based on the operation of the store clerk. In the example shown in FIG. 9A, there is one tab (tab area T1), but the POS terminal 20-1 displays the number of tabs (tab Areas T1, T2, T3, .

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

An image GA02 at the bottom left of the screen indicates the state of the other terminal (POS terminal 20-2) (specifically, normal mode). An image GA03 at the bottom left of the screen indicates the state of the other terminal (POS terminal 20-3) (specifically, it is in full self mode).

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

The small screen SG01 allows the customer to select a payment method. The customer selects either cash, credit or electronic money as the payment method on the small screen SG01. If the customer wishes to use cash as the payment method, the customer may insert cash (deposit) before selecting cash as the payment method on the small screen SG01. The POS terminal 20-1 clears the small screen SG01 when any payment method is selected on the small screen SG01. Also, if cash is inserted before the payment method is selected on the small screen SG01, the POS terminal 20-1 processes it as if cash was selected as the payment method, and clears the small screen SG01.

9A is displayed on the clerk-side display unit 210, the POS terminal 20-1 causes the clerk-side display unit 210 to display the screen shown in FIG. displays the registration screen as shown in .

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

The 20-2 register button BT12 is a button for designating the 20-2 register (POS terminal 20-2). When the clerk designates the POS terminal 20-2 as the terminal for transmitting the registration information, the clerk operates the 20-2 register button BT12. "(Normal)" indicated on the 20-2 checkout button BT12 indicates that the operation mode of the POS terminal 20-2 corresponding to the 20-2 checkout button BT12 is the normal mode.

The 20-3 register button BT13 is a button for designating the 20-3 register (POS terminal 20-3). When the clerk designates the POS terminal 20-3 as the terminal for transmitting the registration information, the clerk operates the 20-3 register button BT13. "(Full self)" indicated on the 20-3 checkout button BT13 indicates that the operation mode of the POS terminal 20-3 corresponding to the 20-3 checkout button BT13 is the full self mode.

The accounting coupon button BT15 is a button for causing the printing unit 213 to issue an accounting coupon. The store clerk operates the accounting ticket button BT15 when executing the process at the POS terminal 20 that read the accounting ticket (the POS terminal 20 that the customer made the accounting ticket read).

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 sent, the POS terminal 20 in the full self mode is more likely to be in the POS terminal 20 in the normal mode than the POS terminal 20 in the normal mode. is preferable as the destination of the registration information. Since the POS terminal 20 in the normal mode is basically operated by a store clerk (see FIG. 5A), processing (for example, registration processing, customer service, etc.) continues to exist, and registration Even if you send information, there is a high possibility that it cannot be processed immediately, and even if it is vacant (even if there is neither a clerk nor a customer), it is basically vacant in order to immediately respond to customers who want support from a clerk. On the other hand, the POS terminal 20 in full-self mode can transmit the registration information and immediately process it if there is no customer. This is because such problems are unlikely to occur.

In view of the above, whether or not the POS terminal 20 to which the registration information is to be sent is preferable, or if there are multiple destinations to which the registration information is to be sent, the clerk is notified of which one is more preferable. As an example, in FIG. 10A, the outline of the 20-3 register button BT13 corresponding to the POS terminal 20-3 in full self mode, which is relatively preferable as the 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 undesirable, is indicated by a dashed line. It should be noted that the above notification by the outline part is only an example, and the clerk can determine whether the POS terminal 20 to which the registration information is to be sent is preferable or not, or if there are multiple destinations to which the registration information is to be sent, which one is more preferable. The notification mode is not limited as long as it can be recognized. For example, the background color of the button may be displayed in a grayed-down manner if it is relatively undesirable, or a punishment mark or diagonal lines may be added to the entire button. Depending on whether the POS terminal 20 to which the registration information is sent is preferable or not, the display size, shape, and display position of the button may be changed. A badge-style image or the like written as ) may be attached.

When the POS terminal 20-1 displays the registration screen as shown in FIG. The screen SG01 is superimposed on the settlement screen (payment screen) and displayed. In addition, the total amount was 0 yen because the product was not registered on the payment screen (payment screen) of FIG. is registered, the total amount is 215.

When the customer inserts 500 yen while the POS terminal 20-1 displays the registration screen of FIG. displays the registration screen as shown in .

Since the customer has put in 500 yen, 500 is displayed in the display field HR01 at the upper right of the screen in FIG. 11(A). Also, by inserting 500 yen, the settlement will be made at the own terminal (POS terminal 20-1). The buttons (20-2 register button BT12, 20-3 register button BT13, accounting ticket button BT15) are hidden (deleted).

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

The POS terminal 20-1 displays the registration screen shown in FIG. When the customer inserts another 500 yen, a registration screen as shown in FIG. Since the customer has additionally inserted 500 yen, 1000 is displayed in the display field HR01 at the upper right of the screen in FIG. 12(A).

When the POS terminal 20-1 displays the registration screen shown in FIG. 12(A) on the clerk-side display unit 210, the settlement screen (payment screen) shown in FIG. 12(B) is displayed. 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 of FIG. ), the small screen (small window) SG02 is superimposed on the registration screen and displayed, and the settlement screen (payment screen) as shown in FIG. The small screen SG02 notifies the store clerk of the information related to the settlement (total amount, equipment deposit amount (deposit amount)).

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

The message screen MG1 is for notifying the clerk of the change. The POS terminal 20-1 erases the message screen MG1 superimposed on the registration screen without depending on the operation of the store clerk (for example, automatically after a predetermined period of time has elapsed). Note that the POS terminal 20-1 may erase the message screen MG1 displayed superimposed on the registration screen in response to the operation of the store clerk (such as touching the message screen MG1).

Although illustration is omitted from FIG. 14 onward, the POS terminal 20-1 displays the same settlement screen as in FIG. display a corresponding message.

(Operation after mode switching operation)
Next, the operation after the mode switching operation will be described. Since the mode switching button 211a (see FIG. 3B) is a hardware key provided in the key operation unit 211, the clerk can operate the POS terminal 20 in any situation (state). (Extremely speaking, even if the power of the POS terminal 20 is off or if it is out of order, it is possible to press the button itself). In other words, the POS terminal 20 can be operated to switch modes under various circumstances. In other words, the situation of the POS terminal 20 at the time of mode switching operation varies.

For the above reasons, the POS terminal 20 performs an operation according to the situation at the time of the mode switching operation (various situations in which the operation is normal, not in the extreme cases described above) during the mode switching operation. . In other words, 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, the operation mode is basically switched from the normal mode to the full self mode, Although 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 situation (state) in which the mode switching operation is performed. Including, 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.
Specific examples will be described below.

(initial state)
The POS terminal 20-1 in the normal mode executes mode switching processing for switching the operation mode from the normal mode to the full self mode when the mode switching button 211a is operated in the initial state. Mode switching processing is also referred to as mode transition processing. Therefore, in the normal mode POS terminal 20-1, when the mode switching button 211a is operated in the initial state, the operation mode is changed from the normal mode to the full self mode. Execute mode transition processing for transition.

As described above, the initial state is a state in which no products have been registered yet, and no payment (settlement) has been made (selection of payment method, insertion of cash, registration of vouchers, etc.) and nothing is done about the customer (such as a state where the membership card is not read, etc.). In other words, the initial state is a state in which no product is registered, cash is not inserted, payment type is not selected, coupons are not registered, and customer information is not yet acquired.

For example, the POS terminal 20-1 in the normal mode, as shown in FIG. , the normal mode is switched to the full self mode (mode switching processing is executed), and a registration start screen is displayed on the customer-side display unit 205 as shown in FIG. 7A.

(cash insertion only state)
When the mode switching button 211a is operated while the POS terminal 20 is in the cash-only state (product unregistered, cash has been inserted, payment type unselected, coupons unregistered, customer information unacquired). , the deposited cash is released (deposit information cancellation processing is executed), and the initial state is set.

FIG. 15A is a display example of the POS terminal 20 in normal mode. Specifically, FIG. 15(A) shows a cash-independent state (merchandise unregistered, cash inserted (15 yen has been inserted in FIG. 15(A)), payment type unselected, coupons unregistered, customer 10 shows a registration screen on the store clerk's display unit 210 (in which information has not yet been obtained).

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

For example, when the POS terminal 20-1 in the normal mode displays the registration screen of the cash insertion only state on the clerk side display section 210 as shown in FIG. If so, the inserted cash is released (deposit information cancellation processing is executed), and as shown in FIG. Display the registration screen in the initial state. Note that since the cash has been released, 0 is displayed in the display field HR01 of the tab area T1 in FIG. 15B.

(Single state of payment type selection)
The mode switching button 211a is operated when the POS terminal 20 is in the single payment type selection state (product unregistered, cash uninserted, payment type selected, vouchers unregistered, customer information unobtained). In this case, the selected payment type is canceled (the payment type information cancellation process is executed), and the initial state is set.

FIG. 16A is a display example of the POS terminal 20 in normal mode. Specifically, FIG. 16A shows a single payment type selection state (merchandise not registered, cash not inserted, payment type selected (“Credit” selected in FIG. 16A), vouchers not registered. , customer information unacquired state)). An icon I1 in the tab area T1 indicates that the payment type "credit" has been selected.

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

The message screen MG2 notifies the salesclerk of the payment type (specifically, that the selection of the payment type has been canceled). The POS terminal 20 erases the message screen MG2 superimposed on the registration screen without depending on the clerk's operation (for example, automatically after a predetermined period of time has elapsed). Note that the POS terminal 20 may erase the message screen MG2 displayed superimposed on the registration screen in response to the clerk's operation (such as a touch on the message screen MG2).

For example, when the POS terminal 20-1 in the normal mode displays the registration screen of the single payment type selection state on the clerk side display unit 210 as shown in FIG. When operated, the selected payment type is canceled (settlement type information cancellation processing is executed), and a message screen MG2 is superimposed on the clerk side display section 210 as shown in FIG. 16(B). display the initial registration screen. Since the payment type has been canceled, the icon I1 in the tab area T1 is deleted in FIG. 16(B).

(Individual voucher registration status)
The mode switching button 211a is operated when the POS terminal 20 is in the gift certificate registration only state (product unregistered, cash not inserted, settlement type unselected, gift certificate registered, customer information unacquired). If so, the registered coupons are canceled (the coupons information cancellation process is executed), and the initial state is set.

For example, the mode switching button 211a is operated while the POS terminal 20-1 in the normal mode is displaying the registration screen of the product ticket registration only state on the store clerk side display unit 210 (not shown). In this case, the registered coupons are canceled (the coupons information cancellation process is executed), and although not shown, the coupons (specifically, , a registration screen in an initial state superimposed with a message screen for informing the store clerk that the registration of the coupons has been canceled is displayed.

(Individual product registration status)
When the mode switching button 211a is operated when the POS terminal 20 is in the product registration independent state (product registered, cash not inserted, payment type not selected, vouchers not registered, customer information not yet acquired). , cancels the product information (executes product information cancellation processing) and returns to the initial state.

For example, when the POS terminal 20-1 in the normal mode displays the registration screen of the product registration only state on the clerk side display section 210 as shown in FIG. If so, the registered product is canceled (product information cancellation processing is executed), and although not shown, the product is displayed on the display unit 210 on the store clerk side (specifically, product registration is canceled). An initial registration screen is displayed on which a message screen for notifying the clerk of the cancellation is superimposed.

(Individual customer information acquisition state)
The mode switching button 211a is operated when the POS terminal 20 is in the customer information acquisition only state (product unregistered, cash uninserted, payment type unselected, coupons unregistered, customer information acquired). In this case, the acquired customer information is taken over (customer information takeover processing is executed), and the normal mode is switched to the full self mode (mode switching processing is executed).

FIG. 17A is a display example of the POS terminal 20 in normal mode. Specifically, FIG. 17(A) shows a state in which customer information is acquired alone (merchandise not registered, cash not inserted, payment type not selected, coupons not registered, customer information already acquired (member card in FIG. 17(A) 10 shows a registration screen on the clerk-side display unit 210 in the state of (acquired information of). An icon I2 in the tab area T1 indicates that the member card information has been acquired.

FIG. 17B is a display example of the POS terminal 20 in full self mode. Specifically, FIG. 17B shows how the customer-side display unit 205 displays "membership number XXXXX" on the registration start screen (see FIG. 7A). "Membership number XXXXX" is customer information (specifically, membership card information) that has been handed over.

For example, when the POS terminal 20-1 in the normal mode displays the registration screen of the customer information acquisition only state on the clerk side display section 210 as shown in FIG. When operated, the acquired customer information (membership number, which is information on the membership card) is taken over (customer information transfer processing is executed), and normal mode is switched to full self mode (mode switching processing is executed) Then, as shown in FIG. 17B, the customer-side display unit 205 displays a registration start screen displaying "membership number XXX". In addition, the customer information is handed over (displayed) to the screen after the registration start screen (registration screen in FIG. 7(B), all or part of each settlement screen in FIGS. 8(A) to 8(E)). ).

(Registration status of cash-inserted product)
The mode switching button 211a is operated when the POS terminal 20 is in a cash-inserted product registration state (product registered, cash inserted, payment type unselected, coupons unregistered, customer information unacquired). In this case, the payment information and product information are taken over (payment information transfer processing and product information transfer processing are executed), and the normal mode is switched to the full self mode (mode switching processing is executed).

FIG. 18A is a display example of the POS terminal 20 in normal mode. Specifically, FIG. 18(A) shows a cash-inserted product registration state (product registered (canned beer has been registered in FIG. 18(A)), and cash has been inserted (15 yen has been inserted in FIG. 18(A)). ), payment type unselected, coupons unregistered, and customer information unacquired)).

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

For example, when the POS terminal 20-1 in the normal mode displays a registration screen for registering cash-inserted merchandise on the clerk-side display section 210 as shown in FIG. When operated, the deposit information (15 yen) of the inserted cash and the registered product information (canned beer information) are inherited (execution of deposit information transfer processing and product information transfer processing). , the normal mode is switched to the full self mode (mode switching processing is executed), and as shown in FIG. display the registration screen. The customer information may be handed over (displayed) on screens subsequent to the registration screen. Also, since there is already a deposit of 15 yen (because cash is treated as being selected), the payment method selection screen (see FIG. 8A) may not be displayed.

(Registration status of cash receipts)
When the POS terminal 20 is in a state of registering cash-inserted coupons (product unregistered, cash inserted, payment type unselected, coupons registered, customer information unacquired), the mode switching button 211a is operated. If so, the deposit information and coupon information are inherited (deposit information takeover processing and coupon information takeover processing are executed), and the normal mode is switched to the full self mode (mode switching processing is executed). ).

For example, although not shown, the POS terminal 20-1 in the normal mode displays the registration screen of the registration status of cash-inserted coupons on the clerk-side display unit 210, and the mode switching button 211a is operated. In such a case, the deposit information of the inserted cash and the registered coupon information are taken over (the receipt information takeover process and the coupon information takeover process are executed), and the normal mode is changed to the full self mode. After switching (executing mode switching processing), a registration screen displaying coupon information and deposits is displayed on the customer side display unit 205, although not shown.

(related to customer detection)
The POS terminal 20 may be equipped with a sensor (for example, a camera for photographing the customer side) capable of detecting whether or not there is a customer around the terminal itself (especially the customer side). Alternatively, the ceiling or wall may be provided with a sensor capable of detecting whether or not there is a customer around the POS terminal 20 (particularly on the customer side) (for example, a camera for photographing the customer side, etc.). If the POS terminal 20 is configured to be able to detect whether or not there is a customer around the POS terminal 20 (especially on the customer side), the POS terminal 20 detects that there is a customer around itself when the mode switching button 211a is operated. The behavior, including whether to switch the operation mode, may vary depending on whether or not there is.

Instead of or in addition to the method using the sensor, the POS terminal 20 is based on whether or not it has been operated for a predetermined time (whether or not a predetermined time has passed since the last time it was operated). or based on both), it may be determined whether or not there is a customer around the own terminal.

(customer detection only state)
When the POS terminal 20-1 in the normal mode is in a customer detection only state (customer detected, product not registered, cash not inserted, payment type not selected, coupons not registered, customer information not yet acquired), When the mode switching button 211a is operated, the normal mode is simply switched to the full self mode (mode switching processing is executed), and the customer side display section 205 displays a registration start screen. This state is the initial state (product unregistered, cash uninserted, payment type unselected, coupons unregistered, customer information unobtained). there is

(Cash insertion customer detection state)
When the POS terminal 20 is in a cash-insertion customer detection state (customer detected, goods unregistered, cash inserted, payment type unselected, coupons unregistered, customer information unacquired), the mode switching button 211a is pressed. is operated, the deposit information is taken over (deposit information takeover processing is executed), the normal mode is switched to the full self mode (mode switching processing is executed), and the deposit is displayed on the customer side display unit 205. Display the displayed registration screen.

(Product registration customer detection status)

Display the displayed registration screen.

FIG. 19 is an explanatory diagram for explaining various operations after the mode switching operation from the normal mode to the full self mode. Specifically, FIG. 19 shows the states illustrated above (initial state, single cash insertion state, single payment type selection state, single registration of vouchers, single product registration state, single customer information acquisition state, single cash insertion). product registration state, cash-inserted coupons registration state, customer detection single state, cash-insertion customer detection state, product registration customer detection state), various after the mode switching operation from the normal mode to the full self mode in each state This is a summary of the behavior (operation) of

As shown in the upper right of FIG. 19, when the operation mode is switched from the normal mode to the full self mode, the prohibited registration on the customer side is permitted, and the permitted transmission of registered information to other terminals is prohibited. and the issuance of accounting coupons, which had been permitted, is prohibited.

In the above description, specific examples of information displayed in the tab area T1 include the display field HR01 (that is, the deposit amount), the icon I1 (that is, that the payment type "credit" has been selected), and the icon I2 (that is, However, in the tab area T1, for example, the fact that a settlement type other than "credit" has been selected, or the fact that coupons have been registered is displayed. good too. Alternatively or in addition to the above, the tab area T1 displays information indicating that a customer has been detected and that the total amount of input (or the total amount of input plus the total amount of coupons) is greater than or equal to the total amount of merchandise. etc. may be displayed.

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

The "payment type information takeover process" shown in FIG. 20A is executed in the "payment related + customer detection related" of FIG. Specifically, it is executed when the "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, processing and messages correspond. For example, the message on the message screen MG1 in FIG. 15(B) corresponds to the "deposit cancellation message" shown in FIG. 20(B), and the "deposit information cancellation process" shown in FIG. sometimes displayed. Also, for example, the message on the message screen MG2 in FIG. 16B corresponds to the "payment type cancellation message" shown in FIG. displayed when is done.

(Example of operation of POS terminal 20)
FIG. 21A is a flow chart showing an example of the operation of the POS terminal 20. FIG. Specifically, the flowchart of FIG. 21A shows an example of the operation when there is a mode switching operation at the POS terminal 20-1 in normal mode. That is, the flowchart of FIG. 21A starts when the POS terminal 20-1 in normal mode detects the operation of the mode switching button 211a.

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

Step S150: The POS terminal 20-1 confirms the customer detection status. 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 (judgment result) in the RAM 203 or the like.

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

Note that in FIG. 21A, the order is the product registration state, the cash insertion state, the payment type selection state, the coupon registration state, the customer information acquisition state, and the customer detection state. Although confirmed, the order of confirmation is not limited to the order shown in FIG. That is, it does not matter which state is checked first. Also, in FIG. 21(A), check the product registration status, cash insertion status, payment type selection status, voucher registration status, customer information acquisition status, and customer detection status. However, if the operation to be processed is determined, the subsequent confirmation process may be omitted.

21(B), 21(C), 22(A), and 22(B) (steps S160A, S160B, S160C, and S160D) are the It is an example of the process (operation according to the confirmation result) of step S160 of A). Also, the process shown in the flowchart of FIG. 22C is a modification of the process (step S160B) shown in the flowchart of FIG. 21C.

(in the initial state)
The flowchart of FIG. 21(B) shows the process (step S160A) according to the confirmation result (initial state) when the confirmation result is the initial state as an example of step S160 of FIG. 21(A). .

Step S170A: The POS terminal 20-1 executes mode switching processing. 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 of 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 in the initial state), the mode switching process is executed and it switches to full self mode.

(In the case of cash insertion only)
The flowchart in FIG. 21(C) is an example of step S160 in FIG. 21(A), in which the process (step S160B) according to the confirmation result (cash insertion only state) when the confirmation result is the cash insertion only state. is shown.

Step S161B: The POS terminal 20-1 executes deposit information cancellation processing.
Step S162B: The POS terminal 20-1 executes the deposit cancellation message.

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

As described above, as shown in FIG. 21C, when the state at the time of the mode switching operation is the cash insertion only state (when the mode switching operation is performed in the cash insertion only state) Since the mode switching process is not executed, the mode is not switched to the full self mode. 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. 21(B)).

(In the case of single product registration)
The flowchart of FIG. 22A shows, as an example of step S160 of FIG. is shown.

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

As described above, as shown in FIG. 22A, when the state at the time of the mode switching operation is the single product registration state (when the mode switching operation is performed while in the single product registration state) , the mode switching process is not executed, so the mode is not switched to the full self mode, but the product information cancellation process is executed, so the initial state is restored. 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. 21(B)).

(In the case of cash input product registration status)
The flowchart of FIG. 22(B) is an example of step S160 of FIG. S160D).

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

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

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

After the mode switching operation, the initial state is restored, but if the mode is not switched (for example, in the case of cash insertion alone in FIG. 21(C), in the case of product registration alone in FIG. 22(A), etc.) , the mode is switched by performing the mode switching operation again after returning to the initial state. In other words, it has been explained that after the series of processes starting from step S100 in FIG. 21(A) is completed, the mode switching operation may be performed again, if necessary. Alternatively, the mode may be switched during the series of processes described above.

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

Step S164B: Following step S163B (YES), the POS terminal 20-1 displays a small screen (not shown. "Yes" button and "No" button are arranged) for the clerk to decide 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. In other words, it is determined whether or not the store clerk indicates that the mode should not be switched. If the "do not" button is operated, the processing of the flowchart of FIG. 22(C) ends. If the "no" button has not been operated, the process proceeds to step S166B.

Step S166B: The POS terminal 20-1 determines whether or not the "Yes" button has been operated on the small screen. In other words, it is determined whether or not the clerk has expressed his 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 mode switching processing. That is, the POS terminal 20-1 switches from the normal mode to the full self mode. Then, the processing of the flowchart of FIG. 22(C) ends.

According to the example shown in FIG. 22C, the mode is switched as necessary during a series of processes without performing the mode switching operation again. FIG. 22(C) illustrates the case of the single cash insertion state as an example, but the same applies to the case of the single product registration state. Also, when switching from the full self mode to the normal mode (see FIG. 23), or when using other criteria (whether processing by the store clerk or by the customer) (see FIGS. 24 and 25), a series of During the processing of , the mode may be switched as necessary.

In the example shown in FIG. 22(C), the mode is switched as necessary (according to the store clerk's selection), but the mode may be switched automatically (irrespective of the store clerk's selection). . That is, step S170B may always be executed after step S163B (YES). In addition, in the case of product registration alone, in the case of switching from the full self mode to the normal mode (see FIG. 23), and in the case of using other criteria (whether processing by the store clerk or by the customer) is used (see FIGS. See FIG. 25).

FIG. 23 is an explanatory diagram for explaining various operations after the mode switching operation from the full self mode to the normal mode. FIG. 19 above summarizes the behavior (operation) after the operation of the mode switching button 211a when the current operation mode is the normal mode. It summarizes the behavior (operation) after the mode switching button 211a is operated in the case of .

As shown in the upper right of FIG. 23, when the operation mode is switched from the full self mode to the normal mode, the permitted registration on the customer side is prohibited, and the prohibited transmission of registered information to other terminals is permitted. and the issuance of accounting coupons, which had been prohibited, is permitted.

As shown in FIG. 23, when the current operation mode is the full self mode, the statuses are "payment-related + product-related", "payment-related + customer detection-related", "product-related + customer detection-related", " The behavior when there are "multiple payment relationships" is different from the case where the current operation mode is the normal mode mode shown in FIG. That is, when the current operation mode is the full self mode, the information is taken over and switched to the full self mode (see FIG. 19), but when the current operation mode is the normal mode, the information is held, It does not switch to normal mode (see FIG. 23).

As shown outside the table in FIG. 23, when there are "payment-related + product-related", "payment-related + customer detection-related", "product-related + customer detection-related", and "multiple payment-related", information may be taken over and switched to the normal mode. For example, a small screen (not shown. ``Yes'' button and ``No'' button are arranged) is displayed to allow the clerk to decide whether or not mode switching is necessary. button is operated), the information may be taken over and switched to normal mode. Alternatively, the information may be taken over automatically (regardless of selection by the store clerk) to switch to the normal mode.

It should be noted that taking over and holding are common in that they are not canceled. For example, taking over and holding the inserted cash have in common that the cash is not discharged, and taking over and holding the selected payment type do not cancel the payment type. common in Therefore, each process corresponding to "hold information" in FIG. The processing is the same or similar (at most, the difference is whether or not the mode is switched).

(Customer information cancellation processing)
In the above description, if customer information is acquired when the mode switching button 211a is operated (for example, in the case of customer information acquisition only state, etc.), the acquired customer information is inherited ( 19, 23, etc.), the acquired customer information may be canceled. That is, if the POS terminal 20 has already acquired customer information when the mode switching operation is performed, the POS terminal 20 may execute the customer information cancellation process instead of the customer information transfer process. For example, if the POS terminal 20 has already acquired customer information when the mode switching operation is performed, a small screen (not shown) is displayed for the clerk to decide whether to take over or cancel the acquired customer information. A "take over" button and a "cancel" button may be displayed, and the customer information may be taken over or canceled according to the clerk's intention. When the customer information is canceled (when the customer information cancellation process is executed), the mode may or may not be switched (see FIG. 22(C)).

As described above, the POS terminal 20 can change the behavior (operation) after the operation of the mode switching button 211a to the operation mode, the state of cash insertion, the state of selection of payment type, and the registration of goods at the time of the operation. , product registration status, customer information acquisition status, and customer detection status (see FIGS. 19, 23, etc.).

Further, when the mode switching button 211a is operated, the POS terminal 20 performs different mode switching processing instead of or in addition to the mode switching processing that should be performed by operating the mode switching button 211a depending on the situation. Other processing (e.g. payment information cancellation processing, payment information transfer processing, payment type information cancellation processing, payment type information transfer processing, coupon information cancellation processing, coupon information transfer processing, product information cancellation processing, product information transfer processing, customer information cancellation processing, customer information transfer processing).

(another example)
24 and 25 are explanatory diagrams for explaining various operations after the mode switching operation. 19 and 23, the behavior (operation) after the operation of the mode switching button 211a is the state of cash insertion, the state of payment type selection, the state of voucher registration, and the state of product registration at the time of the operation. , customer information acquisition state, and customer detection state. It is explained that it differs according to the state of operation by the store clerk and the state of operation by the customer. 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 for explaining various operations after the mode switching operation from the full self mode to the normal mode.

24 (similar to FIG. 25) is a state in which there is an operation by the clerk, there is no operation by the customer, and there is no customer detection. The "single state of customer-side operation, etc." is, for example, the state of no clerk-side operation, etc., customer-side operation, etc., and no customer detection. The "individual state such as customer detection" is, for example, a state in which there is no operation by the store clerk, no operation by the customer, and the presence of customer detection.

The clerk side operation, etc. means that the clerk's side (see FIG. 2, etc.) operates (for example, operation of the clerk's side display unit 210, operation of the key operation unit (except for the mode switching button 211a), operation of the clerk's side scanner unit 212, etc. one or more of operations, etc.).

The existence of customer-side operation, etc. refers to the operation, etc. on the customer side (see FIG. 2, etc.) (for example, operation of the customer-side display unit 205, operation of the customer-side scanner unit 206, operation of the card payment unit 208, operation of the change dispenser 209, etc.). one or more of operations, etc.).

The membership card or the like may be read by the store clerk (clerk side scanner unit 212 or the like) or may be read by the customer side (customer side scanner unit 206 or the like). Further, in the case of the full-self mode, registration of purchased products is generally performed by the customer (customer-side scanner unit 206, etc.), but may also be performed by the store clerk (store clerk-side scanner unit 212, etc.). double scan mode).

The "both-side operation state" in FIG. 24 (similar to FIG. 25) is, for example, a state in which the clerk side operation is present, the customer side operation is present, and the customer is not detected. The "customer detection state such as clerk side operation" is, for example, the state where clerk side operation is present, customer side operation is not present, and customer detection is present. The "customer detection state such as customer-side operation" is, for example, the state of no clerk-side operation, etc., customer-side operation, etc., and customer detection.

For example, when the mode switching button 211a is operated in the normal mode, the POS terminal 20 operates as shown in FIG. 24 instead of operating as shown in FIG. good too. 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 as shown in FIG. may

Note that the POS terminal 20 operates as shown in FIG. 19 when the mode switching button 211a is operated in the normal mode, and operates as shown in FIG. 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 state of cash insertion and the state of payment type selection at the time of the operation. , the state of gift certificate registration, the state of product 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 changed according to the state of operation by the store clerk and the state of operation by the customer at the time of the operation.

Also, when the mode switching button 211a is operated in the normal mode, the POS terminal 20 operates as shown in FIG. If there is, it may operate as shown in FIG. In other words, 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 determined by the state of the store clerk's operation, etc. If the mode switching button 211a is operated while in the full self mode, the behavior (action) after the mode switching button 211a is operated , the cash input state, the settlement type selection state, the coupon registration state, the product registration state, the customer information acquisition state, and the customer detection state.

By the way, in FIG. 19, there are cases where information is canceled (for example, cash-inserted single state, product registration-single state, etc.) and cases where information is inherited without being canceled (cash-inserted product registration state, cash-inserted customer detection state, etc.). However, the case of canceling information is basically a case where the possibility of the information being unnecessary is higher than the case of taking over the information.

For example, in a state in which cash is only inserted (cash insertion only state), there is a high possibility that the cash insertion is intended, and the possibility that the payment information will actually be used for transactions immediately is not high. In this state (cash insertion only state), payment information cancellation processing is executed to cancel the payment information. This is especially true when the mode switching operation is originally performed in the initial state. In other words, when the mode switching operation is performed in a situation where it can be believed that there is neither a deposit nor product registration (for example, a scene where there are no customers), if only the payment information actually remains, the payment information This is because the possibility of the information being handed over and used is low, so the deposit is discharged and the deposit information is cancelled. In addition, for example, if a product is only registered (single product registration status), it is unlikely that the product registration was intended, or that the product information will actually be used for transactions immediately. In the state (single product registration state), the product information cancellation process is executed to cancel the product information. This is especially true when the mode switching operation is originally performed in the initial state. In other words, if the mode switching operation is performed when there are no customers, and if only the product information actually remains, it is unlikely that the product information will be taken over and used. Therefore, the product information has been canceled.

On the other hand, for example, the state in which cash is inserted and the product is registered (cash-inserted product registration state) is highly likely to be intentional because two operations have been performed. In the product registration state), payment information transfer processing and product information transfer processing are executed, and payment information and product information are transferred.

In FIG. 23, the case of canceling the information and the case of holding the information without canceling the information are similar to those of FIG.

Similarly, in FIG. 24, there are cases where information is canceled (for example, single state such as clerk side operation, single state such as customer side operation, etc.) and cases where information is taken over without being canceled (both side operation state, etc.). The case of canceling is basically a case where there is a high possibility that the information is unnecessary compared to the case of taking over the information.

In other words, the state in which either the clerk side or the customer side is operated (single state such as clerk side operation, single state such as customer side operation) is the state in which both the clerk side and the customer side are being operated (both side operation) state, etc.), the possibility that the state is the intended state and the possibility that the information will actually be used immediately is not high. Therefore, in the state where either the clerk side or the customer side is operated (single state such as clerk side operation, single state such as customer side operation), the information is canceled, and both the clerk side and the customer side are performed. Information is inherited in the state (both sides operation state, etc.).

In FIG. 25, the case of canceling information and the case of holding information without canceling it are similar to those in FIG.

Note that the above description focuses on the overall processing in the POS terminal 20, and states that none of the processing is in progress (goods not registered, cash not inserted, payment type not selected, vouchers not registered, customer information not acquired). ) is referred to as the initial state, but it may also be referred to as the initial state by focusing on some processing. For example, the registration status of a cash-inserted product (product registered, cash deposited, payment type unselected, coupons unregistered, customer information unacquired) is an initial state when focusing on the overall process. However, when focusing only on the state of payment type selection, it can be said that this is the initial state. Also, when focusing on the two states of product registration and payment type selection, it cannot be said to be the initial state, but there are two states of payment type selection and voucher registration. , it can be said that it is an initial state.

(placement layout)
FIG. 26 is an example layout of the POS terminal 20. As shown in FIG. Specifically, FIG. 26A shows a configuration including four POS terminals 20 in full-self mode (hereinafter referred to as configuration A). Configuration A is a configuration suitable for relatively non-busy hours.

After finishing shopping at the counter, the customer goes to one of the four POS terminals 20 in full self-mode, registers the merchandise himself/herself, and pays the bill. The customer may select a POS terminal 20 (an available POS terminal 20 or the like) for processing (registration, settlement) based on the customer's own judgment. You may give instructions to the customer who has finished. Alternatively, an attendant dedicated terminal (not shown) may be installed, and the POS terminal 20 to be processed may be guided to the customer who has finished shopping on the display screen of the terminal. In the case of the configuration A, as shown in FIG. 26A, four systems of accounting leads (flow lines) are formed.

Note that a configuration (configuration A described above or configuration B described later) consisting of a plurality of POS terminals 20 may be referred to as an "island".

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

After finishing shopping at the counter, the customer goes to one of the two POS terminals 20 in normal mode, and the clerk registers the merchandise. After the clerk completes the registration, the registered information is sent to the POS terminal 20 in the semi-self mode (accounting mode), so the customer himself/herself pays the bill. The registration information is generally sent to the POS terminal 20 in semi-self mode (accounting-only mode) in the same lane so as not to disturb the accounting lead line shown in the figure, but is sent to the POS terminal 20 in semi-self mode (accounting-only mode) in another lane. It is also possible to transmit to the POS terminal 20 of .

Next, a general operation for transmitting registration information to the POS terminal 20 in the semi-self mode (accounting mode) on the same lane will be described.

(1) The POS terminal 20 in the normal mode (or the clerk of the device; hereinafter the same applies in the description) starts product registration for a certain customer (customer 1) on the clerk side. After completing product registration for customer 1, the POS terminal 20 in normal mode transmits the registration information of customer 1 to the POS terminal 20 in semi-self mode (accounting mode), which is another terminal.
(2) The POS terminal 20 in the normal mode that has transmitted the registration information of the customer 1 starts registering the products of the next customer (customer 2) on the clerk side. The POS terminal 20 in normal mode is used when customer 1, who is the previous customer, is still in semi-self mode (accounting-only mode) after customer 2's product registration is completed (when customer 1's payment on another terminal has not been completed). , the settlement of the customer 2 is carried out on the customer side of the own terminal. If the next customer (customer 3) appears during the payment of customer 2, the store clerk is available, so the registration of the product for customer 3 is started. In other words, the POS terminal 20 in the normal mode can execute the payment processing for the customer 2 on the customer side and the registration processing for the customer 3 on the clerk side. can be processed).
(3) The POS terminal 20 in the normal mode is used when the previous customer 2 is still on the customer's side of the own terminal after completing the product registration of the customer 3 (when the settlement of the customer 2 is not completed on the own terminal). ), the registration information of the customer 3 is transmitted to the POS terminal 20 in the semi-self mode (accounting mode), which is another terminal.

Next, switching from configuration A to configuration B and switching from configuration B to 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 mode switching operation is performed individually for each of a plurality of POS terminals 20 (four units in the example of configuration A and configuration B) that constitute an "island". The other is a method in which the mode switching operation is performed in any one of the POS terminals 20 (one of the four terminals in the example of configuration A and configuration B) that constitutes the "island". In this method, mode switching of other POS terminals 20 constituting an "island" is also collectively performed by an operation (collective method).

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

As shown in FIGS. 27(A) and 27(B) , the collective method is advantageous in that switching from the configuration A to the configuration B or from the configuration B to the configuration A takes less time and effort than the individual method.

In addition, in order to realize the collective 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. By inquiring the terminal), it switches to an appropriate operation mode (the operation mode shown in column (b) of FIG. 27(A) or column (d) of FIG. 27(A)) in accordance with the switching operation or switching instruction. You should do it like this.

In addition, as shown outside the table in FIG. 27, the mode switching operation in the individual method (the same applies to the collective method) may be performed by hardware keys or by software keys (described later). Further, as an individual method (similar to the batch method), instead of or in addition to the mode switching operation, individual operation modes may be switched by a mode switching instruction from a monitoring terminal or a store clerk's mobile terminal.

In the collective method, a specific POS terminal 20 (for example, a POS terminal 20 frequently used by a store manager (a POS terminal 20 placed at a certain location)) instead of one of the POS terminals 20 is logged in by the store manager. The POS terminal 20, etc., which is connected to the network) may enable the switching of the collective method. For example, when the switch button 211a is operated on a specific POS terminal 20, switching by the collective method is executed, but when the switch button 211a is operated on a POS terminal 20 other than the specific POS terminal 20, may be set so that switching by the batch method is not executed.

Also, in the batch method, a dedicated button or the like for the batch method may be prepared (for example, batch switching button 211b (see FIG. 3B)).

Further, the operation by the batch switching button 211b may be valid for a specific POS terminal 20. FIG. For example, a specific POS terminal 20 (for example, a POS terminal 20 frequently used by a store manager (a POS terminal 20 placed in a certain location)) may be provided with a batch switching button 211b, and a POS terminal other than the specific POS terminal 20 may be switched. The batch switching button 211b may not be arranged on the terminal 20. Also, although the batch switching button 211b may be arranged on all the POS terminals 20, only a specific POS terminal 20 (for example, the POS where the store manager logs in) When the batch switching button 211b is operated on the terminal 20 or the like), switching by the batch method is executed. The same applies to the operation of the accounting-only mode switching button 211c (described later).

Next, the individual switching method will be explained. FIG. 27 is an explanatory diagram for explaining mode switching. In the above, configuration A and configuration B have been described, but the individual switching method described with reference to FIG. For example, it can be applied to a situation in which there is one POS terminal in normal mode, one POS terminal in semi-self (accounting only mode), and two POS terminals in full-self mode.

Assuming an example of two types of operation modes (normal mode and full self mode), it has been described that the operation mode is switched in order each time the mode switching button 211a is operated. Even if there are two types of operation modes, each time the mode switching button 211a is operated, the operation modes may be switched in order, as in the case where two types of operation modes exist. If there are three or more operation modes, multiple operations are required to switch to the desired operation mode.

FIG. 28 is an explanatory diagram for explaining mode switching. The individual method (1) shown in FIG. 28 is an explanation of an example in which three types of operation modes (normal mode, full-self mode, and semi-self (accounting-only mode) are switched in order. The individual method (1) shown in FIG. In the case of 1), since it switches from "normal mode" → "full self mode" → "semi-self (accounting mode)", for example, if the current operation mode is normal mode, switch to semi-self (accounting mode) This requires two operations.

If a plurality of mode switching operations are prepared, the number of operations to switch to the desired operation mode can be reduced. In the individual method (2) shown in FIG. 28, when the mode switching operation 1 (for example, operation of the switching button 211a in FIG. 3) is performed, the normal mode and the full self mode are switched in order, and the mode switching operation is performed. 2 (for example, operation of the accounting-only mode switching button 211c in FIG. 3), 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 according to 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 (similarly when the mode switching operation 2 is performed), the current operation mode is "semi-self (accounting mode)". If so, it may be switched to the operation mode (“normal mode” or “full self mode”) before “semi self (accounting mode)”.

Alternatively, in place of the individual method (1) or the individual method (2), a number of mode switching buttons corresponding to each operation mode may be prepared so that the operation mode corresponding to the operated mode switching button is switched. good.

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

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

In full-self mode, the customer himself/herself packs the purchased products. As shown in FIGS. 29A and 29B, the person (customer) who packs the purchased commodities in a bag hangs a bag (a plastic shopping bag, a carry-on bag) on the arm 301 standing from the bag receiving plate 300. As shown in FIGS. bag the purchased products. In the case of the bag receiving state, since the arm 301 stands on the side of the person (customer) who packs the purchased products (that is, the customer side (see FIG. 2)), the person (customer) who packs the purchased commodities is placed on the side of the bag. Since the bag is located on the downstream side, it is easy to pack purchased products.

FIG. 29(C) shows a state of the bag receiver suitable when the POS terminal 20 is in the normal mode. In the normal mode, the store clerk basically packs the purchased product (for example, every time the product is registered, the bag is packed while the customer is paying the bill). As shown in FIG. 29(C), the person (clerk) who packs the purchased commodities puts the bag on the arm 302 standing from the side of the POS terminal 20 and packs the purchased commodities. In the bag-receiving state, the bag-receiving plate 300 does not interfere, so that a person (clerk) who packs the purchased commodities can easily hang the bag, and since the bag is located on the downstream side, it is easy to pack the purchased commodities.

FIG. 29(D) shows the state when the bagging is not used. When the bag holder is not used, as shown in FIG. 29(D), the bag receiving plate 300 rotates (rotates toward the front side in the figure) so as to align with the side surface of the housing, and the arm 302 moves toward the housing. Folded on the side. In order that the bag receiving plate 300 is properly fitted to the side surface of the housing of the POS terminal 20, a storage portion (recess, groove, etc.) for housing the arm portion 301 is provided at a position facing the arm portion 301 on the side surface of the housing. good too.

If necessary (for example, when switching the POS terminal 20 from another operation mode to the full-self mode), the store clerk removes the bag receiving plate 300 stored as shown in FIG. Rotate to position (A). Note that the bag receiving plate 300 may be rotated automatically (instead of manually by the store clerk) by providing a driving unit for controlling the rotation of the bag receiving plate 300 . When switching from the full-self mode to another operating mode, the opposite operation may be automatically performed.

In addition, the clerk, if necessary (for example, when switching the POS terminal 20 from another operation mode to the normal mode), folds the folded arm 302 as shown in FIG. ) position. It should be noted that the arm 302 may be automatically raised by providing a driving unit for controlling the raising of the arm 302 . When switching from the normal mode to another operating mode, the opposite operation may be automatically performed.

In the semi-self (accounting only mode), the state shown in FIG. 29(A) or the state shown in FIG. 29(D) is suitable. For example, after product registration by the clerk, when the customer moves to the terminal, the bagging of the purchased product has already been completed (for example, in the bag receiving state of FIG. 29(C), the clerk The state shown in FIG. 29(D) is suitable for cases such as when a bag is packed at the time of registration. On the other hand, after product registration by the sales clerk, when the customer moves to the terminal, packing of the purchased product is not completed (when the customer moves to the terminal with the shopping basket), FIG. The state shown in (A) is suitable.

As described above, the embodiments have been described with reference to the drawings. According to the above embodiments, when the mode switching operation is performed, the POS terminal 20 is appropriately operated according to the situation (state) at the time of operation. be able to.

For example, as shown in FIGS. 19 and 23, when a mode switching operation is performed, the POS terminal 20 changes the operation mode, the state of cash insertion, the state of selection of It operates appropriately according to the status of class registration, the status of product registration, the status of customer information acquisition, and the status of customer detection.

For example, as shown in FIGS. 24 and 25, when a mode switching operation is performed, the POS terminal 20 changes the operation mode, the state of operation by the store clerk, and the state of operation by the customer at the time of operation. Also, it operates appropriately 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 performs the mode switching process in place of or in addition to the mode switching process depending on the situation at the time of the operation. , Different from the mode switching process, suitable other processing (for example, payment information cancellation processing, payment information transfer processing, payment type information cancellation processing, payment type information transfer processing, coupon information cancellation processing, coupon information takeover process, product information cancellation process, product information takeover process, customer information cancellation process, customer information takeover process).

Alternatively, when the mode switching operation is performed, if some information remains (if it is not in the initial state), the POS terminal 20 can , the operation after the operation is different.

For example, when cash is only inserted (cash insertion only state) or when a product is only registered (product registration only state), it is judged that the possibility of the state being intentional is not high. However, when the information is canceled but the cash is inserted and the product is registered (cash inserted product registration status), it is determined that there is a high possibility that the condition is intentional, and the information is canceled. It has not been canceled (see FIGS. 19 and 23).

Further, for example, in a state in which either the clerk side or the customer side is operated (single state such as clerk side operation, single state such as customer side operation), there is a high possibility that the state is intended. However, when both the store clerk and the customer are in a state of operation (both side operation state, etc.), it is determined that there is a high possibility that the state is intentional, and the information is canceled. is not canceled (see FIGS. 24 and 25).

It should be noted that the above-described embodiment is an example, and the specific configuration is not limited to the above-described embodiment, and includes design and the like within the scope of the invention.

For example, in the above embodiment, when a plurality of pieces of information exist when a mode switching operation is performed and the information is not canceled, all of the existing pieces of information are not canceled. It is also possible to cancel part of the plurality of pieces of information and not cancel part of the information.
For example, in the above-described embodiment, when cash is inserted and merchandise is registered (cash-inserted merchandise registration state), both the deposit information and the merchandise information are inherited (see FIG. 19) or held. (See FIG. 23), the payment information is canceled, and the product information is inherited (or may be retained).

That is, when the mode switching operation is performed, one cancellation process (for example, payment information cancellation process in the above example) and one transfer process (for example, product information transfer process in the above example) shown in FIG. and may be executed.

In addition, in the above embodiment, when the state at the time of the mode switching operation is the single cash insertion state, the payment information is always canceled (see FIGS. 19 and 23), but the cash insertion status (see FIGS. 19 and 23) The amount of money inserted, the number of inserted coins, bills or coins, etc.).

For example, if the total amount of money invested is less than a predetermined amount, it is determined that the possibility of the money being invested is not high, and the payment information is canceled. In such a case, it may be determined that there is a high possibility that the input was intended, and the deposit information may be inherited or retained.

Further, for example, if the total number of inserted coins (coins, banknotes) is less than a predetermined number, it is determined that the possibility of the insertion being unintentional is not high, and the payment information is canceled. is equal to or greater than a predetermined number, it may be determined that there is a high possibility that the input was intended, and the deposit information may be handed over or retained.

Further, for example, if a coin has been inserted, it is determined that the possibility of the insertion being unintentional is not high, and the deposit information is canceled. It may be determined that there is a high possibility that the input was intended, and the deposit information may be inherited or retained.

Also, for example, regardless of the total number of inserted coins, if only coins or banknotes have been inserted, it is determined that the possibility of the insertion being unintentional is not high, and the payment information is canceled. If coins and banknotes have been inserted, it may be determined that there is a high possibility that the insertion was intended, and the deposited information may be inherited or retained.

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

For example, if the total amount of gift certificates (total amount of registered gift certificates) is less than a predetermined amount, it is unlikely that the registration was intended, and the gift certificate information On the other hand, if the total amount of vouchers exceeds a predetermined amount, it is highly likely that the registration was intended, and the voucher information will be inherited or retained. can be

In addition, for example, if the total number of gift certificates (total number of registered gift certificates) is less than a predetermined number, it is judged that the possibility of the registration being intentional is not high, and the gift certificates While trying to cancel the information, if the total number of vouchers exceeds a predetermined number, it is judged that the possibility of the registration being intentional is high, and the voucher information is inherited or retained. You may do so.

Also, for example, regardless of the total number of gift certificates, if only a single type of gift certificate is registered (for example, two A gift certificates), the registration may be intended. On the other hand, if multiple types of vouchers are registered (for example, one A voucher and one B voucher), , it may be determined that there is a high possibility that the registration is intended, and the voucher information may be inherited or retained.

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

For example, if the total price of the product (total price of registered products) is less than a predetermined amount, it is determined that the registration is not likely to have been intended, and the product information is canceled. If the total product price is equal to or greater than a predetermined amount, it may be determined that there is a high possibility that the registration was intended, and the product information may be inherited or retained.

Also, for example, if the total product score (total number of registered products) is less than a predetermined number, it is determined that the registration is unlikely to be intentional, and the product information is canceled. On the other hand, if the total number of product points is equal to or greater than a predetermined number, it may be determined that the registration is likely to be intentional, and the product information may be inherited or retained.

In the above embodiment, the operation after the mode switching operation is varied according to the state at the time of the mode switching operation. may In other words, the operation may be changed according to the time elapsed after entering each state. For example, when the state when the mode switching operation is performed is the cash insertion only state, the operation may be changed according to the elapsed time from the cash insertion.

For example, the POS terminal 20 stores the time when cash is inserted, and if the state when the mode switching operation is performed is the cash-only state, the cash-insertion time (a plurality of times) is stored. If the time elapsed from the time of the last cash injection is longer than a predetermined time, the deposit information is canceled, and if the time elapsed from the time of the cash injection is less than the predetermined time. The deposit information may be inherited or held. It should be noted that the process may be changed by combining the situation of the above-mentioned cash insertion (amount of money inserted, number of inserted bills or coins, etc.) and the elapsed time from the cash insertion time. Alternatively, the elapsed time from the cash-insertion time may be regarded as one of the situations of cash-insertion.

Also, for example, the POS terminal 20 stores the time when the product was registered, and if the state at the time of the mode switching operation was the single product registration state, the product registration time (over a plurality of times) If the time elapsed since the last product registration time is longer than a specified time, the product information will be canceled, and if the time elapsed since the time the cash was inserted is less than the specified time, may inherit or retain the product information. It should be noted that the process may be differentiated by combining the status of product registration (amount of money, points, 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 conditions of product registration.

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 corresponding to the state when the mode switching operation is performed). However, what kind of processing is to be executed (what kind of operation is to be performed) may be notified before the processing is actually executed. For example, when a certain action is performed after the mode switching operation, an OK button that displays that the action will be performed and asks the store clerk to refuse the action before the action is actually performed. and NG buttons may be displayed, and when the NG button is operated, the corresponding operation may not be performed, and when the OK button is operated, the corresponding operation may be performed. The same applies when the batch switching button 211b or the checkout 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 collective switching button 211b, and a software key corresponding to the accounting dedicated mode switching button 211c), the mode switching button of the software key is operated. The same applies to cases.

In addition, in a mode in which the operation mode is switched by a software key (a mode having a software key in place of or in addition to the hardware key, etc.), the 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 included) may display information that notifies what kind of processing is actually executed (what kind of operation will be performed).

In addition, after the mode switching operation (operation of hardware keys, software keys, etc.), multiple types of operation modes (individual operation modes, operation modes related to the entire "island" such as configuration A, configuration B, etc.) can be selected in a manner that can be selected by the store clerk. etc.) may be displayed (for example, displayed on the clerk-side display unit 210 or displayed on a mobile terminal such as a smart phone or a tablet terminal used by the clerk) to switch to the operation mode selected by the clerk.

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

Also, instead of or in addition to the above, information regarding switching of "islands" 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 mobile terminal used by the store clerk may be assigned an "island". A notification prompting the mode switching may be made. The store clerk may check and determine the congestion status in the store, but it may be determined automatically using a camera in the store (a camera installed on the ceiling or on the POS terminal 20), or the POS terminal may determine the congestion status. It may be determined automatically based on the operating status of 20. Also, instead of or in addition to the congestion situation in the store, information regarding the switching of "islands" 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, the schedule is set so that at 20:00 a notice is given to prompt switching from configuration B to configuration A, and according to the schedule (at 20:00), the configuration starts from configuration B. A notification prompting switching to A may be made.

Also, instead of or in addition to the above notification, the "island" mode may be switched according to a predetermined schedule. For example, since the number of customers is large until 20:00, the configuration B may be operated, and the schedule may be set so that the operation is switched to the configuration A around 20:00 when the number of customers begins to decrease.

In addition, when it is determined that the switching key that normally only switches the mode of the device itself is before or after the scheduled switching time (for example, 19:50 to 20:10) as described above, switching of the device itself is performed. , switching to "island", or the like may be displayed. In other words, depending on a certain mode switching operation (operation of hardware keys, software keys, etc.), there are cases where it is possible to switch only the own device, and there are cases where it is possible to switch between the own device and the "island". may

In addition, in a mode in which the operation mode is switched by a software key, instead of or in addition to the information associated with the software key to notify what kind of process is actually executed (what kind of operation), Information for notifying the various states described above (various states shown in FIGS. 19, 23, 24, 25, etc.) may be displayed. Information such as information displayed in the tab area T1 (information related to the selected payment type, acquired customer information, registered gift certificate information, etc.) may be displayed as information for notifying various states.

Also, the POS terminal 20 can be operated by pressing a button on an external device that can be wired or wirelessly connected to the POS terminal 20 instead of or in addition to the hardware key (mode switching button 211a) or the above-described software key as the mode switching operation. (Hardware keys provided on the external device or software keys displayed on the screen of the external device) can be accepted, and when button operations on the external device are accepted, mode The same control as when the operation of the switching button 211a is accepted may be performed.

Also, as already partially explained, 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 store clerk), The same control as when the operation of the mode switching button 211a is accepted may be performed. As described above, in a mode in which a mode switching instruction is received from another terminal, the POS terminal 20 itself may also have mode switching means (hardware key, software key), but the POS terminal 20 itself It is not necessary to have a mode switching means.

It should be noted that mode switching operations (including mode switching instructions from other terminals) may be allowed only when the operator is a specific store clerk (according to the authority of the operator). For example, when a store manager or the like is logged into the POS terminal 20, the mode switching operation is enabled (specifically, controlled as shown in FIGS. 19, 23, 24, and 25), and a part-time worker or the like is logged in. In some cases, the mode switching operation may be invalidated (an error or the like may be made unconditionally 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). 1, when the subtotal key is operated, instead of (switching to) the registration screen, a sub-plan screen for displaying the information displayed on the small screen SG02 may be displayed.

In the above embodiment, the POS terminal 20 is provided with one printing unit 213 that can be rotatably changed from the clerk side to the customer side and from the customer side to the clerk side (see FIGS. 2 to 4). Instead of one printing unit 213, two printing units (a printing unit fixedly facing the store clerk and a printing unit fixedly facing the customer) may be provided.

In the above embodiment, when the registration information is transmitted to another terminal, the clerk designates (selects) the terminal to which the registration information is to be transmitted (destination). may specify that the registration information is to be sent without specifying the terminal to which the registration information is to be sent. In other words, only the send button may be arranged. In a mode in which the store clerk specifies only the transmission without specifying the destination terminal of the registration information, the terminal on the transmission side selects one terminal as the destination according to a predetermined priority, and registers it in the selected terminal. Send information.

For example, when transmitting registration information from the POS terminal 20-1 to the other terminals (POS terminal 20-2, POS terminal 20-3), the POS terminal 20-3 in full self mode is usually assigned the predetermined priority. It may be higher than the POS terminal 20-2 in full-self mode (the registration information may be preferentially transmitted to the POS terminal 20-3 in full-self mode).
