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 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.

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, for example, a bar code (such as a product code) attached to a product. Further, the customer-side scanner unit 206 may optically read a code (a bar code, a two-dimensional code, etc.) printed on an accounting ticket (registered trademark).

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, etc.). The card settlement unit 208 of this embodiment includes a card recognition unit (reading unit), a display unit, and an operation unit. Note that the card recognition unit may recognize various types of cards (for example, membership cards, point cards, etc.) that are not directly used for payment (settlement).

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 (buttons) and receives various inputs from the store clerk.
The clerk-side scanner unit 212 is a scanner unit for a clerk, and optically reads, for example, a bar code (product code, etc.) attached to a product or a clerk code attached to a clerk's name tag.

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 store 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 changed automatically (mechanically controlled, etc.) according to transition (switching) of operation modes (details will be described later), for example. Note that whether the orientation of the printing unit 213 is correct or incorrect may be detected by a sensor or the like.

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 registration processing and the customer executes settlement processing. That is, as shown in FIG. 5B, the POS terminal 20 in the normal mode is in the registration mode on the store 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 in its own terminal and paying out in its own terminal, as well as a function of registering products in its own terminal and paying out in 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 in 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 transition (switching))
Next, transition (switching) of the operation mode of the POS terminal 20 will be described. The operation mode of the POS terminal 20 is switched according to an explicit mode switching operation (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 modes and easily switch operation modes. That is, when the mode switching button 211a is present at the corner of the key operating unit 211, for example, compared to the case where the mode switching button 211a is present near the center of the key operating unit 211, for example, the mode switching button 211a to be operated is Since the number of other 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 upper right corner (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 sales 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 only 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 .

In addition, the POS terminal 20 changes the operation mode according to another operation (for example, reading a salesclerk code, etc.) other than the explicit mode switching operation by the salesclerk. In addition, the POS terminal 20 is not dependent on the operation of a store clerk, etc., and is subject to predetermined conditions (elapsed time, predetermined time (schedule), and other time-related conditions, commands with other terminals (POS terminal 20, monitoring terminal), etc.). The operation mode is changed based on the conditions related to the transmission and reception of information, etc.). It should be noted that, as described above, when the operation mode is changed in the own terminal, the operation mode after the change may be notified to the other terminal.

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.

(Display example of POS terminal 20)
7 to 24 are display examples on the POS terminal 20. FIG. FIG. 7A shows an example of display on the customer-side display section 205 of the POS terminal 20-3 in full self mode. Specifically, FIG. 7A shows the display contents of the registration start screen before starting the registration process.

In FIG. 7A, a registration start button BT30 at the bottom right of the screen is a button for instructing the start of product registration.

FIG. 7B is a display example of the customer-side display section 205 of the POS terminal 20-3 in full self mode. Specifically, FIG. 7(B) 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 a registration screen in which no products have been registered yet (initial registration state). For convenience of explanation, 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 an example of display on the customer-side display section 205 of the POS terminal 20-3 in full self mode. Specifically, 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 is a display example of the customer-side display section 205 of the POS terminal 20-3 in full self mode. Specifically, 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. 8C is a display example of the customer-side display section 205 of the POS terminal 20-3 in full self mode. Specifically, FIG. 8C 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 is a display example of the customer-side display section 205 of the POS terminal 20-3 in full self mode. Specifically, 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. 8E is a display example of the customer-side display section 205 of the POS terminal 20-3 in full self mode. Specifically, FIG. 8(E) shows the display contents of the settlement screen (receipt screen) displayed when the change is taken away. 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)). .

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.

FIG. 10A shows an example of display on the clerk's side display section 210 of the POS terminal 20-1 in the normal mode. Specifically, FIG. 10A shows a case where one product (canned beer) is registered and the payment method has not yet been determined (when neither the payment method has been determined nor cash has been inserted). shows the display contents of the registration screen of That is, the POS terminal 20-1 displays the registration screen (initial registration screen) of FIG. A registration screen as shown in FIG. 10A is displayed on the display unit 210 .

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 cash register button BT12 is a button for designating the 20-2 cash register (POS terminal 20-2). When the store clerk designates the POS terminal 20-2 as the terminal for transmitting the registration information (including via the store controller 10; the same shall apply hereinafter), 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.

That is, in general, the POS terminal 20 in the normal mode is in the state of being used by a clerk, but the POS terminal 20 in the full-self mode is in the state of not being used by the clerk. If the registration information is transmitted to the POS terminal 20 in the normal mode that is being used by the clerk, the process may be delayed and become inefficient. Therefore, the POS terminal 20 in the full-self mode not being used by a clerk is more suitable as a transmission destination of the registration information than the POS terminal 20 in the normal mode being used by a clerk.

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.

In view of the above, although the details will be described later, there are cases where the transmission of registration information to the POS terminal 20 in the normal mode in the clerk's use state is prohibited (for example, the "no button BT22" in FIGS. 18A and 18B). ” is prohibited). If the transmission of the registration information to the POS terminal 20 in the normal mode in which the clerk is in use is prohibited, inefficiency does not occur, and the processing can be performed efficiently as a whole.

In addition, although the details will be described later, the prohibition of sending the registration information to the POS terminal 20 in the normal mode in the clerk's use state may be canceled (for example, the "do button BT23" in FIG. 18A or the button BT23 in FIG. 18B ), the prohibition is released when the “Yes (payment only) button BT24” or “Yes (register also) button BT24” is operated). In other words, in a case where it is not inefficient to transmit the registration information to the terminal that is being used by the store clerk, the registration information can be transmitted as appropriate, so that the processing can be performed efficiently. Alternatively, in a case where not sending the registration information to the terminal in use by the store clerk is rather inefficient, the registration information can be sent as appropriate, so that the processing can be performed efficiently. The cases where sending the registration information to a terminal in use by a clerk does not cause inefficiency are, for example, cases where the clerk is attached but can be processed immediately if the registration information is sent, or where the clerk is actually is not attached. Cases in which not sending registration information to a terminal in use by a clerk would rather be inefficient include, for example, cases in which cash settlement cannot be made at the own terminal due to a hardware or software failure, lack of change, etc., hardware If you cannot issue a receipt on your own terminal due to a hardware or software failure, out of paper, etc., a specific payment type (credit card payment, electronic money payment, etc.) payment, etc.) cannot be settled.

After that, the POS terminal 20-1 may transmit the registration information to the POS terminal 20-2 based on the response from the POS terminal 20-2. Specifically, when the POS terminal 20-2 instructs the POS terminal 20-2 to perform the settlement processing (OK response, response by the “Yes button BT27) on the small screen SG06), the POS terminal 20-1 starts the settlement processing. The registration information to which information (flag) to the effect that it will be added may be sent to the POS terminal 20-2.

Note that the display of the small screen SG06 in FIG. 20A may be omitted. That is, when the POS terminal 20-1 transmits the registration information to the POS terminal 20-2 based on the operation of the "do button BT23" on the small screen SG04 in FIG. When the registration information is transmitted to the POS terminal 20-2 based on the operation of the "do (payment only) button BT24" on the small screen SG05), the POS terminal 20-2 displays the small screen SG06 on the clerk side display unit 210. 20B may be displayed on the customer side display unit 205 without displaying .

The 20-1 register button BT11 is a button for designating the 20-1 register (POS terminal 20-1). When the clerk designates the POS terminal 20-1 as the terminal for transmitting registration information, the clerk operates the 20-1 register button BT11. "(Normal)" indicated on the 20-1 checkout button BT11 indicates that the operation mode of the POS terminal 20-1 corresponding to the 20-1 checkout button BT11 is the normal mode.

FIG. 21A shows an example of display on the clerk's side display section 210 of the POS terminal 20-2 in the normal mode. When the POS terminal 20-1 transmits the registration information to the POS terminal 20-2 based on the operation of the "do (register also) button BT25" on the small screen SG05 of FIG. 18B, the registration information is received. The POS terminal 20-2 may display a small screen (small window) SG07 as shown in FIG. In other words, when the POS terminal 20-2 receives the registration information to which information indicating that the registration process is to be started is added, a small screen SG07 as shown in FIG. may be displayed.

The small screen SG07 in FIG. 21A indicates whether the terminal (the POS terminal 20-2, which is the designated terminal) does not perform the registration process based on the registration information, or whether the terminal performs the registration process based on the registration information. is made to be selected by the clerk on the receiving side. That is, the clerk of the POS terminal 20-2 operates the "no button BT26" when not performing the registration process, and operates the "yes button BT27" when performing the registration process. Note that while the small screen SG07 is being displayed, operations on the small screen SG07 (operations of the "do button BT26" and "do button BT27") are prioritized, and other operations are disabled. If the POS terminal 20-2 receives the registration information during the processing of another customer, the small screen SG07 may be displayed during the processing of the other customer.

The POS terminal 20-2 does not perform the registration process based on the registration information transmitted from the POS terminal 20-1 when the "no button BT26" on the small screen SG07 shown in FIG. 21A is operated. For example, the POS terminal 20-2 may ignore the registration information and notify the POS terminal 20-1, which is the transmission source of the registration information, that registration processing will not be performed.

FIG. 21B is an example of display on the clerk's side display section 210 of the POS terminal 20-2 in the normal mode. The POS terminal 20-2 displays a registration screen as shown in FIG. good too.

(Prohibition and cancellation of transmission of registration information to POS terminal 20-2 in normal mode)
The POS system 1 of the present embodiment has been described above. According to the POS system 1 of the present embodiment, for example, the POS terminal 20-1 in normal mode uses another POS terminal 20-2 in normal mode as a destination. When sending the registration information, confirmation is made with the sales clerk on the sending side whether or not to send the registration information (FIGS. 18A, 18B, step S802 in FIG. 30, step S1802 in FIG. 31). , step S2802 in FIG. 32A).

In other words, the POS terminal 20-1 prohibits (temporarily prohibits, temporarily prohibits) transmission of registration information addressed to the other normal mode POS terminal 20-2. Also, the POS terminal 20-1 notifies that transmission of registration information addressed to the POS terminal 20-2 in the normal mode is prohibited.

Also, when the POS terminal 20-1 in normal mode transmits registration information to another POS terminal 20-2 in normal mode as a destination, the clerk on the transmitting side performs an operation to the effect of transmission in the above confirmation. In this case, the registration information is sent to the POS terminal 20-2 (see steps S845 and S855 in FIG. 30, step S2865 in FIG. 32A, etc.).

In other words, the POS terminal 20-1 cancels the prohibition of sending registration information to the POS terminal 20-2. More specifically, after notifying that transmission of registration information to the POS terminal 20-2 in the normal mode as a destination is prohibited, the clerk on the transmission side performs an operation to the effect that transmission is performed. The above prohibition of transmission has been lifted.

Further, when the normal mode POS terminal 20-1 transmits registration information to another normal mode POS terminal 20-2 as a destination, the POS terminal 20-2, which is the destination of the registration information, transmits the registration information based on the registration information. The clerk on the transmitting side (the clerk logged in to the POS terminal 20-1) can select whether the registration processing is also performed based on the registration information or only the settlement processing is performed based on the registration information (FIG. 18B). , steps S845 and S855 in FIG. 30, steps S1845 and S1855 in FIG. 31, etc.). In addition, the POS terminal 20-2, which is the destination of the registration information, displays information that can be selected by the clerk on the transmitting side (that is, the instruction contents for the clerk on the receiving side (the clerk logged in to the POS terminal 20-1)). (See FIGS. 20A and 21A).

In other words, when the POS terminal 20-1 transmits registration information to the POS terminal 20-2 in normal mode as a destination, the POS terminal 20-1 transmits the registration information together with the other clerk (the clerk logged in to the POS terminal 20-2). instruction information (instruction information on how to process the registration information (only settlement and also registration); in this embodiment, special information (flag)) is transmitted.

(Prohibits execution of either payment on your own terminal or payment on another terminal)
Further, according to the POS system 1 of the present embodiment, the POS terminal 20-1 in the normal mode, when cash is inserted into the change dispenser 209, the other terminals (the POS terminal 20-2, the POS terminal 20 -3), the buttons (20-2 cash register button BT12, 20-3 cash register button BT13, accounting ticket button BT15) used for payment are hidden (FIG. 11(A), step S160 in FIG. 25, See step S260 in FIG. 26, etc.). The same applies when the payment type is selected (see step S160 in FIG. 25, step S260 in FIG. 26, etc.).

In other words, when the POS terminal 20-1 is to settle the account at its own terminal (POS terminal 20-1), before the actual settlement (for example, while the registration process is being performed), the other terminal ( Transmission of registration information to the POS terminal 20-2 and POS terminal 20-3) is prohibited, and issuance of accounting coupons is also prohibited.

On the other hand, the POS terminal 20-1 in normal mode issues a subtotal button BT10 used for settlement on its own terminal (POS terminal 20-1) and an accounting ticket when there is a declaration by the transmission reservation button. The accounting ticket button BT15 used when doing so is hidden (see FIG. 23(A)). When the POS terminal 20-1 in the normal mode is declared by the accounting coupon issue reservation button, the subtotal button BT10 used for settlement at its own terminal (POS terminal 20-1) and the other terminal The send buttons (20-2 checkout button BT12, 20-3 checkout button BT13) used to send the registration information to are hidden (see FIG. 24A). In addition, the POS terminal 20-1 in normal mode hides the subtotal button BT10 used for settlement at its own terminal (POS terminal 20-1) when there is a declaration by the other terminal settlement reservation button. (See FIG. 24B, see step S170 in FIG. 25, step S270 in FIG. 26, etc.).

In other words, the POS terminal 20-1, when the other terminals (POS terminal 20-2, POS terminal 20-3) are to be used for settlement of accounts, do so before actual settlement (for example, while registration processing is being performed). ), the settlement at the own terminal (POS terminal 20-1) is prohibited.

The POS system 1 of the present embodiment has been described above, but the data configuration, processing flow, display and output modes, etc. can be changed and modified as appropriate.

For example, in the above embodiment, when the normal mode POS terminal 20-1 transmits registration information to the normal mode POS terminal 20-2 as a destination, it is determined whether or not to transmit the registration information to the POS terminal 20-2. is confirmed by the clerk on the transmitting side, whether the POS terminal 20-1 transmits the registration information to a terminal different from the POS terminal 20-2 (specifically, the POS terminal 20-3 in full self mode). It is also possible to have the store clerk on the transmission side confirm whether or not the transmission is successful.

For example, in the small screen SG04 of FIG. 18A, in addition to the "do not button BT22" and "do button BT23", a "button to send to other device (POS terminal 20-3)" is arranged, and "button to send to other device (POS terminal 20-3)" is arranged. When the "send to terminal 20-3) button" is operated, the small screen SG04 is erased, and the settlement process is performed on the POS terminal 20-3 in full self mode instead of the POS terminal 20-2 in normal mode. You may send the registration information to begin with .

Alternatively, instead of the "do button BT23" on the small screen SG04 of FIG. 18A, a "button to send to other device (POS terminal 20-3)" may be arranged. In other words, instead of arranging the 'Yes button BT23' on the small screen SG04, the 'No button BT22' and 'Button to send to other device (POS terminal 20-3)' may be arranged. In other words, the POS terminal 20-1 may prohibit transmission of registration information addressed to the POS terminal 20-2 in normal mode.

In addition to the "do not button BT22", "do (payment only) button BT24", and "do (register also) button BT25" on the small screen SG05 of FIG. button to send (payment only) to another device (POS terminal 20-3)” and “button to send (also register) to other device (POS terminal 20-3)”, and “send (payment only) to other device (POS terminal 20-3)” button" is operated, the small screen SG05 is erased, and the registration information is sent to the POS terminal 20-3 in full self mode instead of the POS terminal 20-2 in normal mode so as to start from the settlement process. When the ``button for sending (also registering) to another device (POS terminal 20-3)'' is operated, the small screen SG05 is erased and the POS terminal 20-2 in the normal mode is switched to the full self mode instead of the POS terminal 20-2. The registration information may be transmitted to the POS terminal 20-3 so that the registration process is started.

Alternatively, instead of the ``do (payment only) button BT24'' on the small screen SG05 of FIG. Instead of the "register also) button BT25", a "button for transmitting (also registering) to another device (POS terminal 20-3)" may be arranged.

Further, in the above embodiment, when the POS terminal 20-1 in normal mode transmits the registration information to the POS terminal 20-2 in normal mode, it is determined whether or not to transmit the registration information to the POS terminal 20-2. However, the POS terminal 20-1 may simply prohibit the transmission of registration information addressed to the POS terminal 20-2 without giving the option. For example, the POS terminal 20-1 does not display the small screen SG04 of FIG. 18A or the small screen SG05 of FIG. The same control as when the "no button BT22" on the screen SG05 is operated may be performed. Note that the POS terminal 20-1 may notify that the transmission of registration information addressed to the POS terminal 20-2 is prohibited.

In addition, the POS terminal 20-1 in the normal mode has an option as to whether or not to transmit the registration information with the POS terminal 20-2 in the normal mode as the destination, and if the registration information is to be transmitted to the destination, the registration information at the destination. Depending on the authority of the clerk on the sending side, whether or not options for how to process the information (only checkout, also registration) may be given. For example, if the authority of the clerk on the transmitting side is high, the small screen SG05 in FIG. In addition, a ``button for sending (payment only) to another device (POS terminal 20-3)'' and a ``button for sending (also registering) to another device (POS terminal 20-3)'' are arranged and displayed. If the authority of the clerk on the sending side is moderate, the small screen SG04 of FIG. 18A or the small screen SG05 of FIG. 18B is displayed. It may not be given (it may simply prohibit transmission of registration information addressed to the POS terminal 20-2 in normal mode).

Further, in the above embodiment, the normal mode POS terminal 20-2, which is the destination of the registration information, gives the reception-side clerk a choice as to whether or not to process the registration information at its own terminal (POS terminal 20-2). Although the case where the option is given has been described (see FIGS. 20A and 21A), whether or not to give the option to the receiving clerk may be changed according to the authority of the receiving clerk. good. For example, if the reception side clerk's authority is high, the small screen SG06 of FIG. 20A or the small screen SG07 of FIG. 21A is displayed. No choice may be given (for example, whether or not to process registration information from other terminals may be processed according to preset contents).

Also, in the above embodiment, how the normal mode POS terminal 20-2, which is the destination of the registration information, processes the registration information (only for settlement and also for registration) at its own terminal (POS terminal 20-2). (See FIGS. 22(A) and 22(B), etc.). It may be different according to authority. For example, if the receiving side clerk's authority is high, the small screen SG08 of FIG. 22(A) or the small screen SG09 of FIG. 22(B) is displayed. No choice may be given (for example, processing may be performed according to preset contents regarding how to process registration information from other terminals).

Further, in the above embodiment, the clerk (the clerk on the sending side or the receiving side) can select how to process the registration information at the POS terminal 20-2 on the receiving side of the registration information (either only for settlement or for registration). However, (see FIGS. 18(B), 22(A), 22(B), etc.), how is the registration information processed (payment only, registration ) may be changed according to the installation position of the POS terminal 20-2. In other words, instead of or in addition to the authority of the store clerk (the store clerk on the sending side or the receiving side), whether or not to take over (whether or not to entrust) the registration processing in the other terminal to which the registration information is sent, the product, etc. (the positional relationship between the other terminal and the product).

For example, for products such as cigarettes, hot snacks, oden, etc., it is convenient to perform the registration processing at the nearest terminal where it is easy to confirm the presence or absence and the remaining quantity and to provide them. In addition, there are cases where only one store stamp is placed in a predetermined place in collection services such as utility bills and home delivery services, but when a store stamp is to be stamped, the store stamp is registered at the nearest terminal. and convenient. Therefore, whether or not the other terminal to which the registration information is sent may take over the registration process may be determined according to whether or not the other terminal is close to the predetermined location of the product or store mark as described above. . For example, when the installation location of the POS terminal 20-2 is close to the predetermined location of the product or store stamp as described above, the POS terminal 20-2 on the receiving side receives from another terminal (POS terminal 20-1) An option (see FIG. 18B, FIG. 22A, FIG. 22B, etc.) is displayed to indicate that the registration process is to be executed (taking over) based on the registration information, and the installation location of the POS terminal 20-2 is displayed. is not close to the predetermined location of the product or store mark as described above, the above options may not be displayed. For each POS terminal 20, whether or not the installation location is close to the predetermined location of the product or store mark as described above (or whether the registration process is executed based on the registration information received from the other terminal) is selected. (whether to display or not) should be set in advance.

In addition, if a novice clerk is requested to perform tasks that have not yet been trained (receipt agency, home delivery, in-store cooking, etc.), efficiency may decrease. , locations related to the business (receipt agent, stamp used for parcel delivery, cooking location).

Further, in the above-described embodiment, as the message based on the instruction information transmitted by another salesclerk (the salesclerk of the POS terminal 20-2) together with the registration information, "Registration from cashier 20-1" on the small screen SG06 of FIG. Do you want to process the information (payment only)?” and “Do you want to process the registration information (also registration) from the cash register 20-1?” in the small screen SG07 in FIG. The content is not limited to this. Also, a plurality of types of messages are prepared, and the clerk on the transmitting side may be allowed to select which message to display.

Further, in the above-described embodiment, response buttons (“No button BT26” and “Yes button BT27”) are displayed on the small screen SG06 of FIG. 20A and the small screen SG07 of FIG. Although it is arranged, only the message may be displayed without arranging the response button (a confirmation button (OK button, etc.) that merely clears the small screen may be arranged). Also, the clerk on the transmitting side may be allowed to select whether or not to arrange the response button.

In the above embodiment, an example using special information (flag) added to the registration information or special information (flag) transmitted together with the registration information has been described as the instruction information. flag, etc.), it may be controlled whether the designated terminal starts from the settlement process or from the registration process. For example, when the designated terminal receives registration information including the total amount, the settlement process may be started, and when registration information not including the total amount is received, the registration process may be started. In other words, the POS terminal 20-1 operates when the "button BT20 for performing only payment processing" on the small screen SG03 of FIG. If it is operated, or if the "do (payment only) button BT24" on the small screen SG05 in FIG. 18B is operated, registration information including the total amount may be sent to the designated terminal. The POS terminal 20-1 also operates when the "button BT21 for registering" on the small screen SG03 of FIG. When the button BT25" is operated, registration information that does not include the total amount may be transmitted to the designated terminal.

In addition, in the above embodiment, in order to reduce the amount of data to be sent and received, a message displayed on the terminal on the receiving side (such as "Would you like to process the registration information (payment only) from the cash register 20-1?") Although the message itself is not sent and received, the message itself to be displayed on the receiving terminal may be sent and received.

Further, in the above embodiment, the POS terminal 20-1 in the normal mode sends registration information to the POS terminal 20-2 in the normal mode as a destination on a small screen (small screen) after pressing the send button (20-2 register button BT12). SG04, small screen SG05) is displayed, and transmission of registration information to the destination (POS terminal 20-2) is prohibited (temporarily prohibited), but the mode of transmission prohibition is not limited to this. For example, it may be prohibited (completely prohibited) by hiding the send button (20-2 register button BT12). Alternatively, the send button may be displayed but operated without reaction, or may be operated to cause an error even though the send button is operated.

In the above embodiment, the POS terminal 20-1 that transmits the registration information performs different processing according to the operation mode (normal mode, full-self mode) of the POS terminal 20 on the receiving side (see FIG. 30). See step S800, etc.), as described above, the normal mode is basically used by the store clerk. In other words, the POS terminal 20-1 performs different processing according to the usage status of the POS terminal 20 on the receiving side (usage status inferred from the operation mode).

Further, in the above-described embodiment, the processing differs according to the operation mode of the POS terminal 20 on the receiving side (see step S800 in FIG. 30). Alternatively, the processing may be varied according to the usage status (actual usage status) of the POS terminal 20 on the receiving side. As an example, in the case of (a) below, the process proceeds to step S801 in FIG. 30 (same processing as in full self mode), and in the case of (b) below, step S802 in FIG. (the same processing as in the case where there is an error)).
(a) When the POS terminal 20 on the receiving side (regardless of operation mode) is not used by a clerk (b) When the POS terminal 20 on the receiving side (regardless of operation mode) is used by a clerk

Further, for example, in addition to the operation mode of the POS terminal 20 on the receiving side, the processing may be varied according to the usage status (actual usage status) of the POS terminal 20 on the receiving side. As an example, in the cases (A), (B), and (C) below, the process may proceed to step S801 in FIG. 30, and in the case of (D) below, the process may proceed to step S802 in FIG. Alternatively, in the case of (A) below, the process may proceed to step S801 in FIG. 30, and in the cases of (B), (C), and (D) below, the process may proceed to step S802 in FIG.
(A) When the POS terminal 20 (full-self mode) on the receiving side is not used by a clerk (B) When the POS terminal 20 (normal mode) on the receiving side is not used by a clerk (C) POS on the receiving side When the terminal 20 (full self mode) is used by the clerk (D) When the receiving side POS terminal 20 (normal mode) is used by the clerk

Whether or not the POS terminal 20 on the receiving side is being used by a store clerk may be determined by a sensor or the like that detects the presence of a person near the terminal. For example, if no person is detected continuously for a predetermined period of time (about 10 seconds), it may be determined that the store clerk is not using it. The sensor may be installed in each POS terminal 20, or may be installed on the ceiling, wall, or the like.

In place of or in addition to the method using the sensor, whether or not the POS terminal 20 on the receiving side is being used by a store clerk is determined (estimated) based on the idle time (non-operating time) after the last operation. may If the idle time is short (for example, if it is less than a predetermined threshold (reference time)), it is determined that the store clerk is using it. ) may be determined not to be used by the store clerk. Note that the threshold value may be different for each store, day of the week, time period, and installation position (each terminal).

Further, in the above embodiment, when cash is inserted (detection of payment), the POS terminal 20-1 uses buttons (20-2 register buttons BT12, 20-3 The checkout button BT13 and accounting ticket button BT15) are hidden (see FIG. 11A, etc.), and when the other terminal settlement reservation button is operated, the subtotal button BT10 used for settlement on the own terminal is turned off. It is hidden (see FIG. 24 (B, etc.)). In other words, by deleting unnecessary buttons, processing by the buttons is prohibited. However, the mode of prohibiting processing is not limited to the method of deleting the button. For example, the button may be displayed (displayed in such a manner that it is recognizable as prohibited), but the operation may not be reacted, or the button operation may be reacted, but an error may occur.

In addition, when the amount of money inserted (deposited amount) is greater than or equal to the purchase amount, rather than when cash is inserted, the button used to pay the bill on another terminal may be hidden, or the button operation may be unresponsive. You may make an error.

In the case of a mode in which the button is hidden when the input amount is greater than or equal to the purchase amount, the display in the display field HR01 of the registration screen is configured to indicate whether the input amount is less than the purchase amount or greater than or equal to the purchase amount. may be displayed. For example, characters such as "greater than or equal to" or "less than" may be displayed, or a mark to the effect that the amount is equal to or greater than the purchase price may be displayed. Also, the character color, character size, thickness and typeface of characters, color of the background (display column), etc. of the amount may be changed depending on whether the amount is less than the purchase amount or greater than the purchase amount. Even if the button is hidden when cash is inserted, it is similarly displayed in such a manner that it can be seen whether the amount of money inserted is less than the purchase amount or is greater than or equal to the purchase amount. good too.

In addition, if the input amount was once more than the purchase amount, but later the purchase amount increases due to product registration, and the input amount is less than the purchase amount, the input amount was greater than the purchase amount in the past. However, since it is less than the purchase amount at the moment, the button will not be hidden, etc., as described above. Note that if the input amount was greater than or equal to the purchase amount in the past but is less than the purchase amount at present (that is, if the input amount was greater than or equal to the purchase amount even once), the button may be hidden. .

Regarding the display in the display field HR01 of the registration screen, regardless of whether or not the input amount is displayed in a manner that indicates whether the input amount is less than the purchase amount or is greater than or equal to the purchase amount, the payment type is selected in the display field HR01 ( determination), information that can identify the selected payment type, read information (for example, information that can identify the type of credit card or electronic money, etc.) may be displayed. . For example, characters, symbols, or pictures (illustrations) corresponding to the selected (or read) credit card or electronic money may be displayed.

In place of or in addition to the display field HR01, information indicating whether the input amount is less than the purchase amount or greater than or equal to the purchase amount and whether or not the payment type has been selected are displayed at other positions on the screen. Information, information that can identify the selected payment type, information that can identify the read information, and the like may be displayed. As an example, the entire area (sheet, tab) “1” in which the display field HR01 is provided may be displayed. For example, the background color of the entire area "1" displays the payment status (information indicating whether the amount invested is less than the purchase amount or is greater than or equal to the purchase amount). , a picture corresponding to the selected credit card or the like may be displayed.

As mentioned above, if you accidentally send transaction information (for example, Even in the case where the transmission was made because the cash was not inserted or the payment type was not selected, etc.), the transmission may be canceled. For example, until the next transaction (product registration, payment, payment type selection for the next customer) is started, a transmission cancellation button (not shown) is displayed, and when the transmission cancellation button is operated, the transmitted transaction information may be returned to the sender. As a result, the customer can insert cash or select the type of payment, and the store clerk can correct the contents of the registered product. In addition, returning to the sender means returning to the original situation (the situation before sending the transaction information by mistake) by pressing the send cancel button, and the transaction information is actually sent and received after the send cancel button is pressed. is not limited to For example, in a mode in which the transmission side retains the registration information even after transmission, the registration side treats the registration information retained after the transmission cancel button is operated as information before transmission, and the reception side discards the registration information. (Can be ignored so as not to be used later).

Further, in the above embodiment, it was explained that when the POS terminal 20-1 does not perform the settlement at its own terminal (when the other terminal settlement reservation button is operated, etc.), it becomes impossible to insert cash into the change dispenser 209. However, more specifically, for example, the slot for cash (banknotes, effects) may be closed (or not opened), or the cash inserted into the slot may be discharged as it is. Also, if the payment is not made on the own terminal, inputting the payment type will not work (see step S170 in FIG. 25, step S270 in FIG. 26, etc.). The small screen SG01 on which each button is arranged may be hidden, each button may be displayed (displayed in a manner that indicates that it is prohibited, etc.) but may not respond to operation, or each button may be displayed. It may be made to react by operation, but an error may occur.

In addition, although the payment types in the above embodiment are cash, credit card, and electronic money (see FIG. 15, etc.), other payment types (for example, gift certificates, coupons, complimentary tickets, various prepaid cards, debit payment, etc.). Note that the POS terminal 20 can be used when a payment is received as part of the total purchase amount (for example, when payment is made for a shortfall in the face value of a gift certificate, etc.), or when there is no payment but change is generated. In such a case (e.g., when using a gift certificate, etc., where change is paid for the purchase of a product less than the face value), it may be determined that the settlement process is executed at the terminal (the terminal where the payment was made).

In addition, in the above embodiment, each POS terminal 20 notifies other terminals of the operation mode after the transition when the operation mode is shifted at the own terminal. Always know the mode of operation. Therefore, when the POS terminal 20-1 transmits the registration information to the other terminal, the POS terminal 20-1 refers to the operation mode of the other terminal that it already knows (that is, without inquiring via the LAN 11), and then transmits the registration information. It is possible to check the operation mode of the other terminal that is the destination (destination). Note that the POS terminal 20-1 may inquire again via the LAN 11 about the operation mode of the other terminal to which the registration information is to be sent when sending the registration information to the other terminal.

In the case of a mode in which the processing is changed according to the usage status of the clerk of the POS terminal of the destination (the POS terminal 20 of the receiving side), each POS terminal 20 changes when the usage status of the clerk at its own terminal changes. By notifying the other terminal of the usage status afterward, the POS terminal 20-1 refers to the clerk's usage status of the other terminal already grasped by the POS terminal 20-1 when transmitting the registration information to the other terminal, It is also possible to check the usage status of the store clerk at the other terminal that is the destination (destination). When the POS terminal 20-1 transmits the registration information to the other terminal, the POS terminal 20-1 may inquire about the clerk's usage status of the other terminal that is the transmission destination.

In other words, the POS terminal 20-1 that transmits the registration data confirms the operation mode of the other terminal that it has already grasped based on the operation for transmitting the registration data, or checks the LAN 11. The operation mode of the other terminal, which is the destination, is determined depending on whether the operation mode of the other terminal, which is the destination, is inquired through the terminal. The same applies to the use of other terminals by shop clerks.

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-described embodiment, the POS terminal 20 includes one printing unit 213 that can be rotatably changed from the clerk side to the customer side and from the customer side to the clerk side (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. In a mode in which destination terminals are selected according to priority, before transmitting registration information to terminals selected according to priority, or when transmitting registration information to terminals selected according to priority, or , After transmitting the registration information to the terminals selected according to the priority, the clerk is notified of which terminal has been selected (which terminal is the destination of the registration information).

For example, when the registration information is transmitted from the POS terminal 20-1 to other terminals (POS terminal 20-2, POS terminal 20-3), the POS terminal 20-3 in the full self-mode is normally given 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). If the registration information is to be sent to the POS terminal 20-2 in the normal mode, which has a lower priority, the same process as when the clerk is using the POS terminal 20-2 (processes after step 802 in FIG. 30). may be executed.

Further, as described above, the predetermined priority order may be determined according to the clerk's use of the POS terminal 20 on the receiving side in addition to the operation mode.

Also, in a mode in which the clerk does not specify the destination terminal (that is, a mode in which the destination terminal is selected according to the priority), a display different from the mode in which the clerk specifies the destination terminal may be performed. For example, when the clerk designates the POS terminal 20-3, the message "The register 20-3 is in full self mode" is displayed (see (B) of FIG. 17). When 3 is selected, it may be displayed that "The destination is register 20-3 (full self mode)." In other words, the clerk may be informed which terminal was selected according to the order of priority.
