Description

The present invention relates to a product sales data processing device and program.

In recent years, there has been a product sales data processing device that can be used by switching between a case where a store clerk performs all product registration and payment operations and a case where a customer performs all product registration and payment operations (for example, see Patent Document 1).

Japanese Patent Application Publication No. 2004-252865

However, if only store staff or customers handle the process from product registration to checkout, the function of shortening the time from registration to checkout may not be fully utilized.

An object of the present invention is to provide a product sales data processing device and program that can efficiently register products.

In order to solve the above-mentioned problems, a product sales data processing device that is one aspect of the present invention provides a customer-side registration section where customers register products, in a position facing the store clerk-side registration section where store clerks register products. A product sales data processing device is provided with a payment section in which a store clerk and a customer make payment, and the switching control of operation modes includes a clerk side registration mode in which a store clerk registers a product and a customer side registration mode in which a customer registers a product. The control means is configured to control the salesperson when the operation mode is in the customer side registration mode during the registration of the product in the customer side registration section or during the payment by the payment section. The present invention is characterized in that the next customer's product registration is permitted in the store clerk side registration section which is in the side registration mode.

Hereinafter, the POS terminals 20-1, 20-2, and 20-3 will be collectively referred to as the POS terminal 20 unless otherwise distinguished. Note that the POS system 1 may further include a monitoring terminal (not shown) that displays the status (operation mode, processing status, etc.) of the POS terminal 20 and controls the POS terminal 20.

The POS system 1 can be introduced into various stores (convenience stores, supermarkets, etc.).

FIG. 2 is a diagram showing an example of installation of the POS terminal 20. As shown in FIG. FIG. 2A is a perspective view of the POS terminal 20 and the like as viewed from the customer side. FIG. 2(B) is a perspective view of the POS terminal 20 and the like as viewed from the store clerk's side. As shown in FIG. 2(A), a counter is placed on the right side of the POS terminal 20 when viewed from the customer side.

FIG. 3 is a diagram showing an example of the appearance of the POS terminal 20. As shown in FIG. FIG. 3(A) is a perspective view of the POS terminal 20 viewed from the customer side. FIG. 3(B) is a perspective view of the POS terminal 20 viewed from the store clerk side. FIG. 4 is a diagram showing a configuration example of the POS terminal 20. As shown in FIG. In FIGS. 3 and 4, the same parts are denoted by the same reference numerals.

Hereinafter, a configuration example of the POS terminal 20 shown in FIG. 4 will be described with reference to FIG. 3. The POS terminal 20 includes a CPU 201, a ROM 202, a RAM 203, a hard disk 204, a customer side display section 205, a customer side scanner section 206, a card payment section 208, a change machine 209, a clerk side display section 210, It includes a key operation section 211, a clerk side scanner section 212, a printing section 213, an audio output section 214, and a communication section 215. These can communicate with each other via a bus. Note that the symbols 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.

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

Hard disk 204 stores various information. For example, instead of the ROM 202, the hard disk 204 may store programs executed by the CPU 201. Further, instead of the RAM 203, information acquired from the outside or information generated during processing may be stored.

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

Note that although the customer-side scanner unit 206 is used when a customer registers a product, the customer may register the product using other methods. For example, if a preset key (button for ordering a product) corresponding to a product is displayed on the customer side display section 205, the customer may operate (press) the preset key to register the product.

The card payment unit 208 is a payment mechanism using various cards (credit cards, prepaid cards such as transportation cards, point cards, etc.). The card payment section 208 includes a card recognition section (reading section), a display section, and an operation section. The card recognition unit magnetically or electrically reads information on various cards. The read information is used for payment (settlement) of purchased products. In addition, when using the recognized information for payment (settlement) of the purchased product (in other words, in the case of credit card payment, prepaid card payment, prepaid card payment, the card recognition unit uses the points held by the point card. In addition to cases where the recognized information is not used for payment (settlement) of the purchased product (e.g., when giving benefits by presenting a credit card, when giving points to a point card) etc.) may also recognize various cards. Note that although the card payment unit 208 of this embodiment includes a card recognition unit (reading unit), a display unit, and an operation unit, the card payment unit 208 may include at least a card recognition unit. Further, the card recognition unit of this embodiment is compatible with contact cards (IC cards, magnetic cards), but instead of or in addition to contact cards, it can be used with non-contact cards (IC cards). It may correspond to.

The change machine 209 (cash payment unit) is a cash payment mechanism, has an inlet for bills and coins, and an outlet for bills and coins, calculates the amount inserted into the inlet, and compares the input amount with the purchase amount. The difference in change amount is calculated and the change is discharged from the discharge port. The change machine 209 faces the customer and is operated by the customer. Note that when banknotes or coins are inserted into the input slot, they are detected by a sensor (detection of insertion, detection of number of coins for each denomination, etc.). The card payment unit 208 and the change machine 209 form a payment unit.

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 section 212 is a scanner section for the clerk, and optically reads various information. For example, the clerk-side scanner unit 212 optically reads a barcode 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, gift certificates, and various cards.

Note that although the clerk-side scanner section 212 is used when a store clerk registers a product, the store clerk may register the product using other methods. For example, if a key corresponding to a product (for example, a key corresponding to a sports newspaper, etc.) is arranged on the key operation unit 211, a store clerk may operate (press) the key and register the product. good. Further, when a preset key corresponding to a product is displayed on the store clerk side display section 210, the store clerk may operate the preset key to register the product.

The printing unit 213 prints and issues various media (receipts, billing tickets, etc.). The printing unit 213 can rotate freely (the direction of the media issuing port) from the clerk side to the customer side and from the customer side to the clerk side. The orientation of the printing unit 213 may be changed manually, or may be automatically changed (mechanically controlled, etc.), for example, based on switching of the operation mode (details will be described later). Note that a sensor or the like may be used to detect whether the printing unit 213 is oriented correctly or incorrectly. Note that switching the operating mode is also referred to as shifting the operating mode.

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

(Summary of each operation mode)
Next, the operation mode of the POS terminal 20 will be explained. POS terminal 20 has multiple operation modes. This operation mode is the operation mode during normal business operations (operation mode related to registration processing and payment processing), and is the aggregation mode for aggregating and inquiring sales and balances, and the operation mode for store clerks, maintenance personnel, etc. to perform setting work and maintenance work. It does not include maintenance mode when training is performed, training mode when new employees are training, etc.

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

In FIG. 5(A), the columns indicate each operation mode, and the rows indicate each function (“Product registration (staff side)”, “Product registration (customer side)”, “Money insertion”, ..., “Customer side”). "Reading of Account Tickets"). The same applies to FIG. 5(B) (however, illustration of each function is omitted in FIG. 5(B)).

In Fig. 5(A) (same as Fig. 5(B)), the "〇" in the column specified by the column and row indicates that the function of the corresponding row is enabled in the operation mode of the corresponding column. . For example, "〇" in the column specified by the column "Normal mode (Standard mode)" and the row "Product registration (Staff side)" indicates that product registration (Staff side) is valid in the normal mode (Standard mode). It shows that. Further, a "-" in a column specified from a column and a row indicates that the function of the row is disabled in the operation mode of the column. For example, a "-" in the column specified from the column "Normal Mode" and the row "Product Registration (Customer Side)" indicates that product registration (Customer Side) is disabled in the normal mode.

(Explanation of each function)
The outline of each function shown in FIG. 5(A) will be explained below.

(Product registration (staff side))
"Product registration (store clerk side)" is a function for registering purchased products on the clerk side (clerk side scanner section 212, clerk side display section 210, key operation section 211). In other words, this is a function that executes the registration process of the purchased product by the store clerk's operations (scanning by the store clerk's scanner section 212, touching the store clerk's display section 210, operating the key operation section 211).

(Product registration (customer side))
"Product registration (customer side)" is a function for registering purchased products on the customer side (customer side scanner section 206, customer side display section 205). In other words, this is a function that executes the registration process of the purchased product by the customer's operation (scanning by the customer side scanner unit 206, touching the customer side display unit 205).

(Inserting money)
"Money insertion" is a function that accepts the insertion of money (banknotes, coins). In other words, it is a function that accepts a payment operation using cash (insertion of money into the change machine 209).

(Sending registration information to other terminals)
"Sending registration information to another terminal" is to send the registration information generated in the registration process to another terminal (another terminal that can execute the payment process, for example, another POS terminal 20) (directly to the other terminal). This is a function to send the information, or indirectly send it to another terminal via the store controller 10, a monitoring terminal, etc. (hereinafter the same).

(Issuance of accounting ticket)
"Issuance of accounting ticket" is a function of encoding the registration information generated in the registration process and issuing a printed medium (accounting ticket).

(Receiving registration information from other terminals)
"Receiving registration information from another terminal" means receiving registration information generated in the registration process of another terminal (directly from another terminal, or indirectly via the store controller 10, monitoring terminal, etc.). This is a function to receive data from other terminals (hereinafter the same). Note that the terminal that has received the registration information from another terminal executes the payment processing based on the registration information.

(Reading the bill)
"Reading a bill" is a function of reading a bill (specifically, a code printed on a bill or coded information). Note that the terminal that reads the bill issued by another terminal executes the payment process based on the registration information obtained by reading the bill.

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

(Normal mode (standard mode))
As shown in FIG. 5A, the normal mode (standard mode) is an operation mode in which product registration (on the clerk's side) is set to valid "0" and product registration (on the customer's side) is set to disabled as "-". In other words, the normal mode (standard mode) is an operation mode in which the registration process is not executed on the customer's side but on the clerk's side, and is, so to speak, a clerk's side registration mode.

In addition, in the normal mode (standard mode), as shown in Figure 5 (A), all functions such as inserting money, sending registered information to other terminals, and issuing accounting tickets are set to "〇". This is the operating mode. That is, in the normal mode (standard mode), the checkout process after the registration process on the clerk's side can be executed by the own terminal or can be executed by another terminal. Specifically, in the normal mode (standard mode), the payment process is executed on the own terminal by accepting the insertion of money into the change machine 209, and the payment process is executed on the own terminal by sending registration information to another terminal (or the payment ticket is sent to the other terminal). (issuing) to have another terminal execute the payment process.

Further, the normal mode (standard mode) is an operation mode in which reception of registration information from other terminals and reading of billing tickets are both enabled as shown in FIG. 5(A). That is, in the normal mode (standard mode), payment processing can be executed based on registration information generated at another terminal. Note that the payment process after receiving the registration information (or after reading the bill) may be executed in the semi-self mode shown in FIG. 5(A). In other words, if registration information is received (or a checkout ticket is read) while in normal mode (standard mode), normal mode (standard mode) automatically changes to semi-self mode (accounting only mode). The payment process may be executed in semi-self mode (accounting only mode). In addition, if you move to semi-self mode (accounting only mode) and execute payment processing, the semi-self mode (accounting only mode) will automatically change to normal mode (standard mode) (permission may be requested from the store staff). You may transition (return) or remain in semi-self mode (accounting only mode).

In addition, in the normal mode (standard mode), at least one of receiving registration information from another terminal and reading a bill may be set to "-".

(Full self mode)
As shown in FIG. 5A, the full self mode is an operation mode in which product registration (on the customer side) is enabled. In other words, the full self mode is an operation mode that assumes registration processing on the customer side, so to speak, a customer side registration mode. However, in full self-mode, product registration (on the store clerk's side) is also valid. In other words, the full self mode is an operation mode that assumes registration processing on the customer's side and also allows registration processing on the clerk's side. Note that a state in which registration processing is performed on both the customer side and the clerk side is sometimes referred to as double scan mode.

In the example shown in Figure 5 (A), in full self mode, product registration (on the clerk's side) is set to valid "〇", but in full self mode, product registration (on the clerk's side) is set to disabled as "-". Good too.

In addition, as shown in Figure 5 (A), the full self mode is an operation mode in which the insertion of money is enabled with "〇" and the transmission of registration information to other terminals and the issuance of accounting tickets are disabled with "-". It is. In other words, the full self mode is an operation mode that assumes payment processing at the terminal.

In addition, as shown in Figure 5 (A), in full self mode, as in normal mode (standard mode), receiving registration information from other terminals and reading billing tickets are both enabled. This is the operating mode. That is, like the normal mode (standard mode), in the full self mode, payment processing can be executed based on registration information generated at another terminal. Note that the payment process after receiving the registration information (or after reading the bill) may be executed in the semi-self mode shown in FIG. 5(A). In other words, if registration information is received (or a checkout ticket is read) while in full-self mode, the mode automatically shifts from full-self mode to semi-self mode (accounting-only mode), and The payment process may also be executed in a special mode (dedicated mode). In addition, if you execute the payment process by transitioning to semi-self mode (accounting only mode), you may automatically transition (return) from semi-self mode (accounting only mode) to full self-mode, or You may leave it in accounting-only mode).

(Semi-self mode (accounting only mode))
In the semi-self mode (accounting only mode), as shown in Figure 5 (A), receiving registration information from other terminals, reading billing tickets, and inserting money are enabled, and product registration (clerk side) is enabled. This is an operation mode in which product registration and product registration (on the customer side) are disabled as "-". In other words, the semi-self mode (accounting-only mode) is an operation mode in which the own terminal does not perform the registration process, and only performs the payment process based on the registration information generated at the other terminal. In addition, since the semi-self mode (accounting only mode) is an operation mode in which registration processing is not executed (registration information is not generated), the transmission of registration information to other terminals is also not possible, as shown in FIG. 5(A). Issuance of accounting tickets is also marked as invalid.

(Normal mode (limited mode))
As shown in Figure 5 (B), the normal mode (restricted mode) is used to send registered information to other terminals and issue check tickets, which was set to valid in the normal mode (standard mode) of Figure 5 (A). and is set to "-" to indicate that it is invalid. In other words, the normal mode (restricted mode) is an operation mode in which the function of causing another terminal to execute payment processing, which is permitted in the normal mode (standard mode), is restricted. Like the normal mode (standard mode), the normal mode (restricted mode) is a clerk side registration mode.

(Semi-self mode (registration only mode))
In the semi-self mode (registration only mode), as shown in Figure 5 (B), product registration (on the clerk's side), transmission of registration information to other terminals, and issuance of checkout tickets are enabled, and product registration ( (Customer side), inserting money, receiving registration information from other terminals, and reading billing tickets are disabled in this operation mode. In other words, the semi-self mode (registration only mode) is an operation mode in which the own terminal exclusively executes the registration process and causes another terminal to execute the payment process. Note that in the semi-self mode (registration only mode), product registration (customer side) is set to invalid because it is assumed that the registration operation is performed by a store clerk. The semi-self mode (registration-only mode) is a clerk-side registration mode, similar to the normal mode (standard mode).

(Operating mode for clerk side and customer side)
The POS terminal 20 treats the customer-side display section 205 and the customer-side scanner section 206 as a customer-side registration section, and the clerk-side display section 210, key operation section 211, and clerk-side scanner section 212 as a clerk-side registration section. It is possible to control the registration unit and the clerk side registration unit as different operation modes. For example, it is possible to set the customer side registration unit in full self-mode to register the current customer's products, and at the same time, set the clerk side registration unit in the normal mode to register the next customer's products. Note that the control between the customer side registration unit and the clerk side registration unit in different operation modes is executed in multiple transactions, and in one transaction, the operation mode is common between the customer side registration unit and the clerk side registration unit. It is.

(About enabling and disabling functions)
In addition, in the above description, the POS terminal 20 performs various functions provided by the POS terminal 20 itself (product registration (staff side), product registration (customer side), money insertion, . . , reading the bill), it was explained that the difference is whether it is valid "〇" or invalid "-". In other words, in the above, the POS terminal 20 originally performs all the functions (product registration (staff side), product registration (customer side), inserting money, ..., reading the bill as shown in FIG. 5A). (For example, as shown in FIG. 5A, when the POS terminal 20 is in normal mode (standard mode), some functions are disabled depending on the operation mode.) Registration (customer side) is disabled (-), and when in full self-mode, sending registration information to other terminals and issuance of billing tickets are disabled (-).

However, the POS terminal 20 only needs to have different executable functions depending on the operation mode, and the POS terminal 20 does not necessarily have all the functions originally, but some of the functions are disabled depending on the operation mode. It is not necessary to have such a configuration. For example, the POS terminal 20 does not have all the functions (programs for realizing the functions) from the beginning, but depending on the operation mode (for example, when switching the operation mode), Obtain and execute a program to realize the function (function corresponding to the function marked as enabled in Figure 5) from the outside (for example, store controller 10, monitoring terminal, server outside the store (cloud, etc.)) In addition, if there is a program to realize a function that is not necessary for the operation mode (a function corresponding to the function marked as disabled in Figure 5) (if it is retained), the program is It may be in an unexecutable state (for example, it may be erased). Note that after a program for realizing an unnecessary function is rendered unexecutable, a program for realizing a necessary function may be acquired and made executable. For example, when switching the operation mode, the POS terminal 20 first makes all programs unexecutable, regardless of the destination operation mode, and then executes The program may also be obtained from an external source and placed in an executable state. In other words, depending on the operation mode, the configuration of the POS terminal 20 may be such that some of the various functions originally provided are disabled, or depending on the operation mode, some of the various functions originally provided may be disabled. It is also possible to provide only appropriate functions.

Above, we have explained the normal mode (standard mode), full self mode, semi-self mode (accounting only mode) in Figure 5 (A), and the normal mode (restricted mode) and semi-self mode (registration only mode) in Figure 5 (B). However, the following description will focus on the normal mode (standard mode), full self-mode, and semi-self mode (accounting-only mode) shown in FIG. 5(A). Note that in the following description, the normal mode (standard mode) may be simply referred to as normal mode. Further, the semi-self mode (accounting only mode) may be simply referred to as the semi-self mode.

(Switching (transition) of operation mode)
Next, switching (transition) of the operation mode of the POS terminal 20 will be explained. Basically, the operation mode of the POS terminal 20 is switched according to an explicit mode switching operation (also referred to as a mode transition operation, which will be described in detail later) by a store clerk. Furthermore, the operation mode of the POS terminal 20 may be switched in accordance with an operation different from the mode switching operation (for example, reading a clerk code, etc.).

Furthermore, the operation mode of the POS terminal 20 may be switched without being operated by a store clerk. Specifically, the operation mode of the POS terminal 20 may be switched in accordance with a mode switching command (mode switching instruction) from another terminal (POS terminal 20, monitoring terminal, mobile terminal, etc.). Further, the operation mode of the POS terminal 20 may be switched according to temporal conditions (for example, the elapsed time since the last operation, a fixed time according to a schedule, etc.). Furthermore, the operation mode of the POS terminal 20 may be switched at the start of processing (for example, at the start of payment processing based on received registration information, at the start of payment processing based on a bill, etc.). Furthermore, the POS terminal 20 may be configured to switch its operating mode at the end of the process (for example, at the end of the payment process based on the received registration information, or at the end of the payment process based on the bill).

FIG. 6 is a diagram illustrating switching of the operation mode of the POS terminal 20. The left side of FIG. 6 shows the combination of operation modes before and after switching (operation mode before switching→operation mode after switching), and the right side shows conditions (an example) for switching the operation modes. For example, the row a indicates that examples of conditions for switching the operating mode from the normal mode to the full self mode include a mode switching operation, a mode switching command, and a predetermined period of time (non-use). In other words, when the operating mode is normal mode, if there is a mode switching operation, a mode switching command, a predetermined period of time elapsed (non-use), etc., the operating mode will switch from normal mode to full self mode. It shows. Note that details of the mode switching operation will be described later.

(Normal mode → Full self mode)
As shown in a, when in the normal mode, for example, a mode switching operation, a mode switching command (a mode switching command specifying full self mode as the destination operation mode, etc.), a predetermined time elapsed (a predetermined time elapsed), etc. (not in use), the operating mode switches from normal mode to full self mode.

(Normal mode → Semi-self mode (accounting only mode))
As shown in b, when in normal mode, for example, a mode switching operation, a mode switching command (a mode switching command that specifies semi-self mode (accounting only mode) as the destination operation mode, etc.), etc. In this case, the operation mode is switched from normal mode to semi-self mode (accounting only mode). Furthermore, while in normal mode, the operating mode may be switched from normal mode to semi-self mode (accounting-only mode) when registration information is received from another terminal or when a checkout ticket is read, for example. .

(Full self mode → normal mode)
As shown in c, if, for example, there is a mode switching operation or a mode switching command (such as a mode switching command that specifies the normal mode as the destination operation mode) while in the full self mode, The operating mode switches from full self mode to normal mode.

(Full self mode → Semi self mode (accounting only mode))
As shown in d, when in full self mode, for example, there is a mode switching operation, a mode switching command (a mode switching command that specifies semi-self mode (accounting only mode) as the destination operation mode, etc.), etc. In this case, the operation mode switches from full self mode to semi self mode (accounting only mode). In addition, when in full self mode, for example, if registration information is received from another terminal or a checkout ticket is read, the operating mode will be switched from full self mode to semi self mode (accounting only mode). Good too.

(Full self mode → double scan mode)
As shown in e, if, for example, a clerk code is read while in the full self mode, the operation mode is switched from the full self mode to the double scan mode. Note that the double scan mode is an aspect of the full self mode (a state in which the function of product registration (on the staff side) is used in addition to the function of product registration (on the customer side); see FIG. 5(A)).

Note that if a clerk code is read while in full self mode, the operation mode may always switch to double scan mode regardless of the product registration state, or the operation mode may be changed to double scan mode regardless of the product registration state. It may be possible to switch to a different operation mode depending on the situation. For example, if a store employee code is read while the product has not yet been registered (in other words, the product has not been registered by the customer), the system will switch from full self mode to normal mode, and If a clerk code is read while a product is being registered (in other words, if the product is being registered by a customer), the system will switch from full self mode to double scan mode. good.

(Semi-self mode (accounting only mode) → normal mode)
As shown in f, when in semi-self mode (accounting only mode), for example, a mode switching operation, a mode switching command (a mode switching command, etc. in which normal mode is specified as the destination operation mode), etc. In this case, the operation mode is switched from semi-self mode (accounting only mode) to normal mode. In addition, when in semi-self mode (accounting only mode), for example, if payment processing (for example, payment processing based on received registration information, payment processing based on checkout ticket) is completed, semi-self mode (accounting only mode) ) to the normal mode.

(Semi-self mode (accounting only mode) → Full self-mode)
As shown in g, when in semi-self mode (accounting only mode), for example, there is a mode switching operation, a mode switching command (a mode switching command that specifies full self mode as the destination operation mode, etc.), etc. In this case, the operation mode switches from semi-self mode (accounting only mode) to full self-mode. In addition, when in semi-self mode (accounting only mode), for example, if payment processing (for example, payment processing based on received registration information, payment processing based on checkout ticket) is completed, semi-self mode (accounting only mode) ) to full self mode.

Note that the mode switching operation may be any operation that specifies the destination operation mode according to the operation. For example, when providing (or displaying) buttons for different destinations, the operation mode may be switched to each destination in response to a mode switching operation by pressing each button. Further, in the case of providing (or displaying) one button whose destination changes each time the button is pressed, the operation mode may be changed each time the button is pressed to switch the mode.

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

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

Note that since the mode switching button 211a is arranged at the corner of the key operation section 211, it is possible to reduce operational errors when switching the operating mode, and it is also possible to easily switch the operating mode. In other words, when the mode switching button 211a is located at the corner of the key operation unit 211, compared to the case where the mode switching button 211a is located near the center of the key operation unit 211, for example, the mode switching button 211a that is the operation target is Since the number of adjacent buttons is small, it is difficult to make operational errors such as operating other buttons in a hurry, and the position of the mode switching button 211a to be operated can be instantly identified, allowing stress-free mode switching operations. It can be performed.

Furthermore, since the mode switching button 211a is arranged at the upper right corner of the key operation unit 211 (the uppermost and rightmost corner), the mode switching operation can be performed not only when the clerk is on the clerk's side but also when the customer is on the customer's side. You will be able to do this. In other words, the clerk on the customer's side usually cannot visually recognize each button on the key operation section 211, but when it comes to the mode switching button 211a located at the upper right corner of the key operation section 211, the clerk on the customer's side reaches out and gropes. Since the mode switching button 211a to be operated can be easily recognized only by the touch of the hand, the clerk on the customer's side can perform the mode switching operation without moving to the clerk's side.

Note that in this embodiment, the mode switching button 211a is placed at the upper right corner of the key operation unit 211, but if it is in a position that can be recognized only by groping (a position that can be recognized relatively easily), the mode switching button 211a can be changed to The switching button 211a may be arranged at a position other than the upper right corner of the key operation section 211. Additionally, instead of or in addition to arranging the mode switching button 211a in a position that can be recognized only by groping (for example, in the upper right corner), it is possible to distinguish it from other buttons even from the customer's perspective. A mode switching button 211a may be formed on the screen. For example, the size of the mode switching button 211a may be made different from the size of other buttons to the extent that it can be distinguished by groping, or the shape of the mode switching button 211a may be made different from the shape of the other buttons. The height of the mode switching button 211a may be different from the height of other buttons (for example, the mode switching button 211a may be made to protrude more than the other buttons). ), the feel of all or part of the surface of the mode switching button 211a (the surface that the hand touches) may be made different from that of other buttons (for example, only the surface of the mode switching button 211a may be made rough or bumpy). It may be a tactile function, or a protrusion or depression may be provided only on the surface of the mode switching button 211a).

Note that in this embodiment, the mode switching button 211a is arranged on the key operation section 211 in consideration of various advantages as described above, but instead of arranging the mode switching button 211a on the key operation section 211 Alternatively, in addition, a mode switching button (not shown) may be arranged on the screen displayed on the clerk side display section 210.

(Operation of each operation mode)
FIG. 7 is a schematic diagram illustrating an outline of the operation in the normal mode. Specifically, FIG. 7 is a schematic diagram showing the flow of processing and the actions of people (clerks, customers) when payment processing is executed on the own terminal in the normal mode. FIG. 8 is a flowchart outlining the operation in normal mode. Specifically, FIG. 8 is a flowchart illustrating an outline of the operation when the terminal executes payment processing in the normal mode.

In the normal mode (the same applies whether the payment process is executed on the own terminal or when the payment process is executed on another terminal), the store clerk scans the customer's purchased products on the store clerk's side (the clerk's scanner section 212, the clerk's display section 210, The key operation unit 211) is used to register (upper row of FIG. 7). In other words, the POS terminal 20 executes the registration process for the purchased product (in the upper row of FIG. ).

When the registration process by the store clerk is completed, the customer checks the total amount of purchased items on the store clerk side display section 210, inserts money (cash) into the change machine 209, or operates the card payment section 208 to make payment. (Bottom row of Figure 7). That is, the POS terminal 20 executes the payment processing in response to the customer's operations (insertion of cash into the change machine 209, operation of the card payment unit 208) (lower part of FIG. 7).

That is, when performing the payment process on the own terminal in the normal mode, as shown in FIG. 8, 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 section 210 or the subtotal key arranged on the key operation section 211) (step S30: YES), the customer side, for example, presses the change machine 209. The payment is made (step S50), and the process is completed. Note that 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, etc.

Note that the customer may wait until the clerk completes the registration process (until the total amount is determined), or may insert cash into the change machine 209 before the registration process is completed. In other words, the POS terminal 20 can accept deposits during the registration process (upper row of FIG. 7).

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

Further, the clerk may wait until the customer completes payment (until the customer takes the change or receipt), or may register the purchased items of the next customer. In other words, the POS terminal 20 can register the purchased products of the next customer during the payment process (lower row of FIG. 7). Further, the clerk may be absent while the customer is making payment (lower row of FIG. 7). In other words, you may finish serving the customer while the customer is making payment.

In addition, when there is change, the POS terminal 20 controls the payout of change and change tags by the change machine 209 in order to prevent forgetting to take change, and uses a sensor etc. to detect when the customer has removed the change and change tags. After this recognition, issuing of a receipt by the printing unit 213 may be controlled. The same applies to other operation modes.

FIG. 9 is a schematic diagram illustrating an outline of the operation in the normal mode. Specifically, FIG. 9 is a schematic diagram showing the flow of processing and the actions of people (clerks, customers) when having another terminal execute payment processing in the normal mode (standard mode). FIG. 10 is a flowchart illustrating an outline of the operation in the normal mode. Specifically, FIG. 10(A) is a flowchart illustrating an outline of the operation when causing another terminal to execute payment processing in normal mode (standard mode). Note that FIG. 10(B) is a flowchart showing the basic flow of operations in other terminals (other devices) in FIG. 10(A).

In the normal mode (the same applies whether the payment process is executed on the own terminal or when the payment process is executed on another terminal), the store clerk scans the customer's purchased products on the store clerk's side (the clerk's scanner section 212, the clerk's display section 210, The key operation unit 211) is used to register (upper row of FIG. 9). In other words, the POS terminal 20 (POS terminal 20-1 in the example of FIG. 9) performs the registration process of the purchased product through the operations of the clerk (operation of the clerk's scanner section 212, clerk's display section 210, key operation section 211, etc.). (upper row of Figure 9).

When the registration process by the store clerk is completed, the customer moves to another POS terminal 20 (POS terminal 20-2 in the example of FIG. 9), checks the total amount of purchased items on the store clerk side display section 210, and then presses the change machine. 209, or operate the card payment section 208 to settle the payment (lower row of FIG. 9). In other words, the other POS terminals 20 execute payment processing based on the customer's operations (insertion of money into the change machine 209, operation of the card payment section 208) (lower part of FIG. 9).

Note that the other POS terminal 20 (POS terminal 20-2) is supplied with information necessary for payment processing (registration information generated at the POS terminal 20-1, etc.).

Note that the store clerk specifies, at the POS terminal 20-1, which POS terminal 20 (in the example of FIG. 9, either the POS terminal 20-2 or the POS terminal 20-3) is to execute the payment process. Alternatively, the clerk issues a medium (ticket) at the POS terminal 20-1 to be read by the POS terminal 20 (in the example of FIG. 9, POS terminal 20-2 or POS terminal 20-3) that executes the payment process. It's okay.

In other words, when having another terminal execute the payment process in the normal mode, as shown in FIG. ). After the subtotal key (for example, the subtotal key displayed on the clerk side display section 210 or the subtotal key arranged on the key operation section 211) is pressed (step S30: YES), for example, a checkout process is executed, etc. When the POS terminal 20 is specified (step S31: YES), registration information is sent to the specified POS terminal 20 (step S32), and the registration side processing is completed.

Incidentally, after specifying another terminal, the clerk can register the purchased product of the next customer (lower row of FIG. 9). Further, the clerk may be absent after specifying another terminal (lower row of FIG. 9).

Further, in the example shown in FIG. 10(A), another POS terminal 20 is specified after pressing the subtotal key, but another POS terminal 20 may be specified without pressing the subtotal key. . For example, a subtotal key and a key for specifying another POS terminal 20 may be arranged on the registration screen (a key for issuing a bill may also be arranged), and a key for specifying a POS terminal 20 may be arranged. The registration information may be transmitted when the key is pressed. In the mode of specifying another POS terminal 20 without pressing the subtotal key, it is not necessary to press the subtotal key after pressing the key for specifying another POS terminal 20.

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

Note that the other POS terminal 20 (POS terminal 20-2 in the example of FIG. 9) that has received the registration information enters the semi-self mode after receiving the registration information (step S40: YES), as shown in FIG. 10(B). (accounting only mode), it shifts (switches) to semi-self mode (accounting only mode). That is, if the current operation mode (at the time of receiving registration information) is the full-self mode (step S41: YES), the transition is made from the full-self mode to the semi-self mode (accounting only mode) (step S42), and the current operation mode is changed to If it is the normal mode (step S43: YES), the normal mode shifts to a semi-self mode (accounting only mode) (step S44). Then, on the customer side, payment is made using the change machine 209, for example (step S50), and the processing on the payment side is completed.

In the example shown in FIG. 10(B), the other POS terminal 20 that has received the registration information shifts to the semi-self mode (accounting only mode) if it is not in the semi-self mode (accounting only mode) after receiving the registration information. However, there is no need to shift to semi-self mode (accounting only mode). In other words, since the payment process is possible even in the normal mode or the full self-mode (see FIG. 5), the payment process may be executed in the normal mode or the full self-mode.

As mentioned above, the normal mode (standard mode) is a function in which the store clerk executes the registration process and then the customer of the own terminal executes the payment process using the registration information generated in the registration process (Figure 7 , see FIG. 8), and a function to send the registration information generated in the registration process to another terminal (another terminal that can execute the payment process; for example, another POS terminal 20) and cause the other terminal to execute the payment process. (See Figures 9 and 10) and the registration information (or information for acquiring the registration information) generated in the registration process is converted into a code (barcode, two-dimensional code, etc.) and printed to issue a payment ticket. This includes a function that causes the other terminal to execute payment processing.

On the other hand, the normal mode (restricted mode) is one of the functions of the normal mode (standard mode) described above, as shown in FIG. A function that allows the terminal to execute the payment process, and a payment ticket that is encoded and printed with the registration information generated in the registration process (or information for acquiring the registration information) is issued, and the payment process is sent to the other terminal. This mode limits the functions that can be executed.

In addition, among the functions of the normal mode (standard mode) described above, there is a function that sends the registration information generated in the registration process to another terminal and causes the other terminal to execute the payment process, and a function that causes the registration information generated in the registration process ( The function of issuing a checkout ticket that is encoded and printed (or information for acquiring the registration information) and having the other terminal execute the payment process is also a function of the semi-self mode (registration-only mode). In other words, the semi-self mode can be classified into the registration-only mode and the accounting-only mode, but in the semi-self mode (registration-only mode), as shown in FIG. 5(B), the registration information generated in the registration process is A function that sends data to a terminal and causes another terminal to execute payment processing, and issues a checkout ticket that is encoded and printed with the registration information generated in the registration process (or information for acquiring the registration information). This includes a function that causes the other terminal to execute payment processing. In other words, the semi-self mode (registration only mode) is one of the functions of the normal mode (standard mode) described above, in which the clerk executes the registration process and then uses the registration information generated in the registration process to operate the own terminal. This is a mode in which the ability to perform payment processing on the customer side is restricted. In other words, the semi-self mode (registration only mode) is an operation mode in which registration processing is executed exclusively.

As shown in Figure 5 (A), the semi-self mode (accounting only mode) has the function of receiving registration information generated in the registration process on another terminal and executing the payment process, and the function of receiving the registration information generated in the registration process on another terminal and executing the payment process. Includes a function to read Tao bills and perform payment processing. In other words, the semi-self mode (accounting only mode) is an operation mode in which payment processing is executed exclusively.

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

In the full self mode, the customer registers his or her purchased products on the customer side (customer side scanner unit 206, customer side display unit 205) (upper row of FIG. 11). In other words, the POS terminal 20 executes the registration process of the purchased product in response to the customer's operation (scanning by the customer side scanner unit 206, touching the customer side display unit 205) (upper row of FIG. 11).

When the registration process is completed, the customer confirms the total amount of purchased items on the customer side display section 205, inserts cash into the change machine 209, or operates the card payment section 208 to make payment (see the bottom row of Fig. 11). ). In other words, the POS terminal 20 executes the payment process based on the customer's operations (insertion of cash into the change machine 209, operation of the card payment unit 208) (lower part of FIG. 11).

That is, in the case of full self-mode, as shown in FIG. 12, the customer side scans the product (step S20: YES) and registers the product (step S21). After pressing the registration completion key (for example, the registration completion key displayed on the customer side display section 205) (step S40: YES), the customer side performs payment using the change machine 209 (step S50), and processes. is completed. Note that the registration completion key related to step S40 is an operation key for completing the registration process, and may also be referred to as a registration completion button, subtotal key, subtotal button, checkout key, checkout button, etc.

In addition, in the full self mode, as shown in FIG. 11, the customer side executes the registration process and the payment process, but this does not mean that the clerk side cannot do anything. In other words, even when the POS terminal 20 is operating in full self-mode, the store clerk can, for example, scan the product (double scan mode) or the store clerk can display various information. Is possible.

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

In the full self-mode, the customer registers his or her own purchased products on the customer side (upper row of FIG. 11, upper row of FIG. 13). In other words, the POS terminal 20 executes the registration process of the purchased product according to the customer's operation (upper row in FIG. 11, (upper row in FIG. 13)).

During the registration process by the customer, the store clerk registers the customer's purchased product (middle row in FIG. 13). That is, the POS terminal 20 executes registration processing based on operations by the customer and registration processing based on operations by the store staff (middle row of FIG. 13).

When the registration process is completed, the customer confirms the total amount of purchased items on the customer side display section 205, inserts cash into the change machine 209, or operates the card payment section 208 to make payment (see the bottom row of FIG. 13). ). That is, the POS terminal 20 executes the payment process in response to the customer's operations (insertion of cash into the change machine 209, operation of the card payment unit 208) (lower part of FIG. 13).

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

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

Note that in the double scan mode, the clerk may wait until the customer completes payment (until the customer takes the change or receipt), or may register the purchased item for the next customer. In other words, the POS terminal 20 can register the purchased products of the next customer during the payment process (lower row of FIG. 13). Further, the clerk may be absent while the customer is making payment (lower row of FIG. 13). In other words, you may finish serving the customer while the customer is making payment.

As shown in FIG. 14(A), when the clerk code is read in full self mode, the operation mode shifts from full self mode to double scan mode, but reading the clerk code is part of the login operation. It may be one. Further, the operation mode may shift from the full self mode to the double scan mode when another operation (for example, a login operation different from reading the clerk code) is performed in the full self mode. Furthermore, when the store clerk no longer performs any operations in the double scan mode (for example, when a predetermined period of time has elapsed since the last operation), the operation mode may shift from the double scan mode to the full self mode.

(Notification of operation mode)
Each POS terminal 20 may notify its current operating mode. For example, each POS terminal 20 may display its current operating mode on the clerk-side display section 210. Specifically, each POS terminal 20 displays a screen having an operation mode display column 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 column on the screen. It's okay. Additionally, each POS terminal 20 displays a screen on the clerk side display section 210 on which images (for example, button-like images) corresponding to each operation mode are arranged, and the current operation mode of the own terminal is displayed on the screen. An image that does not correspond to the current operation mode may be displayed in a different display manner from that of an image that does not correspond to the current operation mode (for example, in a display manner that is more conspicuous than the display manner of other images). For example, when operating in two operating modes, normal mode and full self-mode, the normal mode image and full self-mode image are always displayed, and when the current operating mode of the own terminal is normal mode, the normal mode image is displayed. The full self mode image may be displayed in a more conspicuous display manner than the full self mode image, and when the current operation mode of the own terminal is the full self mode, the full self mode image may be displayed in a more conspicuous display manner than the normal mode image. . Note that each POS terminal 20 may similarly display its current operating mode on the customer side display section 205 as well.

Further, each POS terminal 20 may notify the current operating mode of another terminal instead of or in addition to the current operating mode of the own terminal. That is, each POS terminal 20 may notify the current operating mode of the other terminal by mutually recognizing the current operating mode of the other terminal. An example of a method in which each POS terminal 20 mutually recognizes the current operation mode of the other terminal is that each POS terminal 20 notifies the other terminal of the operation mode after the transition (the latest operation mode) after changing the operation mode (LAN 11). (via the store controller 10, a monitoring terminal, etc.). Further, each POS terminal 20 may notify 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 notify information according to the current operating mode (operating mode, processing status, etc.) of its own terminal. For example, each POS terminal 20 may display various information on the customer side display section 205 when the current operating mode of the terminal is the full self mode, for example, when the terminal is on standby. Further, the POS terminal 20 may broadcast information according to the current operation mode of another terminal, instead of or in addition to the information according to the current operation mode of the own terminal.

In addition, even if the operating mode is switched by a clerk's operation (mode switching operation, clerk code reading, etc.), if the operating mode is switched without a clerk's operation (mode switching command, predetermined period of time, etc.) Even if the situation is due to progress, etc., the operating mode of the own terminal and other terminals is notified.

(Storing information regarding operation mode)
Each POS terminal 20 may store, as information regarding the operation mode, in which operation mode the transaction (processing) was performed. For example, when the POS terminal 20-1 operating in normal mode (standard mode) executes registration processing and settlement processing for a certain transaction, the POS terminal 20-1 that executed the registration processing and settlement processing information (for example, settlement information) (or in association with information about the transaction), information that the registration process and settlement process for the transaction were performed in normal mode (standard mode) (for example, identifying the operating mode) possible information, etc.) may be stored.

Note that each POS terminal 20 may also store information on which terminal the transaction (processing) was performed. In the above example, the POS terminal 20-1 may store information indicating that the registration process and the payment process were executed at the own terminal (POS terminal 20-1) as information regarding the transaction. More specifically, the POS terminal 20-1 stores its own terminal identification information as the identification information (terminal identification information) of the terminal that executed the registration process, and also stores its own terminal identification information as the terminal identification information of the terminal that executed the payment process. Terminal identification information of the terminal may be stored. Alternatively, the POS terminal 20-1 may store the terminal identification information of its own terminal as the terminal identification information of the terminal that executed the entire process (registration process, payment process).

Further, for example, first, the POS terminal 20-1 operating in the normal mode (standard mode) executes registration processing for a certain transaction, and then the POS terminal 20-2 operating in the semi-self mode (accounting only mode) However, when the settlement process is executed for the transaction based on the registered information in the above registration process, the POS terminal 20-2 that executed the settlement process uses the information related to the transaction (for example, settlement information) as (or information that the registration process for the transaction was performed in normal mode (standard mode), as well as information that the settlement process for the transaction was performed in semi-self mode (accounting-only mode). Information may also be stored. Further, in addition to the above, the POS terminal 20-1 that executed the registration process may also store information indicating that the registration process regarding the transaction was performed in a normal mode (standard mode).

In the above example, the POS terminal 20-2 that executed the payment process stores information that the registration process was executed at another terminal (POS terminal 20-1) as transaction information, and stores the information that the registration process was executed at the other terminal (POS terminal 20-1). Information indicating that the payment process was executed at the terminal 20-2) may be stored. More specifically, the POS terminal 20-2 stores the terminal identification information of another terminal (POS terminal 20-1) as the information (terminal identification information) of the terminal that executed the registration process, and also stores the terminal identification information of the other terminal (POS terminal 20-1) as the information (terminal identification information) of the terminal that executed the registration process. The terminal identification information of the own terminal (POS terminal 20-2) may be stored as the terminal identification information of the terminal. In the above example, the POS terminal 20-2 that executes the payment process receives the terminal identification information and operation mode (specifically, normal mode) of the POS terminal 20-1 that executed the registration process. It is sufficient if the identifying information can be obtained. For example, information identifying the terminal identification information and operation mode of the POS terminal 20-1 is supplied from the POS terminal 20-1 side to the POS terminal 20-2 side (for example, sending and receiving information as registration information, It suffices if the system is supplied via the network.

Furthermore, each POS terminal 20 may store information regarding the transition (switching) of the operation mode as information regarding the operation mode. For example, when the operation mode of the POS terminal 20-1 transitions from one operation mode to another, the POS terminal 20-1 determines the operation mode transition time and the operation mode to which it transitioned. information (for example, information that allows identification of the operation mode after the transition) may be stored. In addition, the POS terminal 20-1 also provides information on which operation mode it has transitioned from to which operation mode (for example, information that allows identification of the operation mode before transition, information on the operation mode after transition, as well as the time of transition of the operation mode). information that can identify the user) may also be stored.

Note that each POS terminal 20 will not be able to change its operating mode even if the operation mode is switched by an operation by a store clerk (by mode switching operation, reading a clerk code, etc.), or if the operation mode is switched without any operation by a store clerk ( (in the case of a mode switching command, the passage of a predetermined time, etc.), information regarding the transition of the operation mode may be stored. In the above case, each POS terminal 20 stores information on the basis of which the operation mode was changed (for example, information indicating that the operation mode was changed due to an operation by a store clerk with the clerk code "XXX", terminal identification information "XXX" It may also be possible to store a message that the operation mode has been changed by a mode switching command from the POS terminal 20 (e.g. "x").

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

Further, the information regarding the operation mode stored as described above may be output (displayed, transmitted, printed, etc.) as necessary. For example, the POS terminal 20 may include information on the receipt output in the full self-mode that indicates that the process (registration process, payment process) was performed in the full-self mode (information in a form that only the clerk can recognize, or (Information in a form that can be recognized even on the computer) may also be printed. Receipts output in other operating modes may also be printed in the same manner. Further, for example, the POS terminal 20 (or the monitoring terminal) may display the operation mode at the time of processing. As an example, when a transaction number (information that can identify a transaction) is input on a predetermined search screen, the POS terminal 20 (or monitoring terminal) performs registration processing and settlement processing for the corresponding transaction. For at least one of them, the terminal on which the process was performed (terminal identification information, etc.) and the operation mode (information that allows identification of the operation mode) may be displayed.

(Screen display on POS terminal 20 in normal mode)
Next, the screen display on the POS terminal 20 in normal mode will be explained. 15 to 20 are display examples on the POS terminal 20 in normal mode. Specifically, FIG. 15(A), FIG. 16(A), FIG. 17(A), FIG. 18(A), FIG. 19(A), and FIG. 20(A) all show normal mode (standard mode). ) is a display example on the clerk side display section 210 of the POS terminal 20. 15(B), FIG. 16(B), FIG. 17(B), FIG. 18(B), FIG. 19(B), and FIG. 20(B) all show the POS terminal 20 in normal mode (standard mode). This is an example of a display on the customer side display section 205.

Here, the first POS terminal 20-1 of the first POS terminal 20-1 to the third POS terminal 20-3 will be described as its own terminal (POS terminal 20). Further, the description will be made assuming that the operation mode of the second POS terminal is the normal mode, and the operation mode of the third POS terminal 20-3 is the full self mode.

FIG. 15(A) shows the display contents on the registration screen in the initial state on the clerk side display section 210. In the following explanation, the initial state means, unless otherwise specified, a state in which no processing is in progress, for example, a state in which no products have been registered yet, and no payment has been made yet. (e.g., no payment method has been selected, no cash has been inserted, no gift certificates have been registered, etc.), and no action has been taken regarding the customer (e.g., membership card, etc., has not been read). be.

In FIG. 15A, the first tab area T1 at the top right of the screen is a tab corresponding to each display content (display screen). The POS terminal 20 can interrupt the registration process for the customer (the reason for the interruption is to return to the store to add purchased items, etc.), and then proceed to the registration process for the next customer. In other words, the POS terminal 20 displays a new registration screen for the next customer while retaining (memorizing) the display content (registration content) of the registration screen for the customer, based on the clerk's operation. In the example shown in FIG. 15(A), there is one tab (the first tab area T1), but the POS terminal 20 displays the number of tabs (the first 1 tab area T1, 2nd tab area T2, 3rd tab area,...), the registration screen to be enabled (activated) is switched according to the tab operation (press).

Information that identifies the tab from other tabs (the number "1" in the example of FIG. 15(A)) is displayed in the first tab area T1. Further, the first tab area T1 is provided with a display column HR01 for displaying the deposited amount from the customer. Further, although not displayed in the example shown in FIG. 15(A), various information (described later) in addition to the above is displayed in the first tab area T1.

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

FIG. 15(B) shows the display content on the customer side display section 205 in the initial state. In other words, when the POS terminal 20 displays the registration screen as shown in FIG. 15(A) on the clerk side display section 210, the POS terminal 20 displays a small screen as shown on FIG. 15(B) on the customer side display section 205. The screen (small window) SG01 is displayed superimposed on the payment screen (deposit screen).

The small screen SG01 allows the customer to select a payment method. The customer selects cash, credit, or electronic money as a payment method on the small screen SG01. If the customer desires cash as the payment method, he or she may insert cash (deposit) before selecting cash as the payment method on the small screen SG01. The POS terminal 20 erases the small screen SG01 when any payment method is selected on the small screen SG01. Further, if cash is inserted before the payment method is selected on the small screen SG01, the POS terminal 20 processes it as if cash has been selected as the payment method and erases the small screen SG01.

The POS terminal 20 displays the registration screen shown in FIG. 15(A) on the clerk side display section 210, and when the clerk registers a can of beer, the clerk side display section 210 displays the registration screen shown in FIG. 16(A). Display a registration screen like this.

In FIG. 16(A), the 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 the product registration.

The 20-2 register button BT12 is a button for specifying the 20-2 register (second POS terminal 20-2). The store clerk operates the 20-2 register button BT12 when specifying the second POS terminal 20-2 as the terminal to transmit the registration information. "(Normal)" shown on the 20-2 cash register button BT12 indicates that the operation mode of the second POS terminal 20-2 corresponding to the 20-2 cash register button BT12 is the normal mode.

The 20-3 register button BT13 is a button for specifying the 20-3 register (third POS terminal 20-3). The clerk operates the 20-3 checkout button BT13 when specifying the third POS terminal 20-3 as the terminal to transmit the registration information. "(Full Self)" shown on the 20-3 cash register button BT13 indicates that the operation mode of the third POS terminal 20-3 corresponding to the 20-3 cash register button BT13 is the full self mode.

The checkout button BT15 is a button for causing the printing unit 213 to issue a checkout. The store clerk operates the bill button BT15 to cause the POS terminal 20 that read the bill (the POS terminal 20 that the customer caused the bill to read) to execute the process.

In addition, when comparing the POS terminal 20 in normal mode and the POS terminal 20 in full self-mode as the POS terminal 20 to which registration information is sent, the POS terminal 20 in full self-mode is better than the POS terminal 20 in normal mode. is preferable as the destination for registration information. Since the POS terminal 20 in the normal mode is basically operated by a store clerk (see FIGS. 7 and 8), processing (for example, registration processing, customer service, etc.) continues, and registration Even if you send information, there is a high possibility that it will not be able to be processed immediately, and even if it is vacant (even if there is no staff or customer present), it is generally left open in order to immediately respond to customers who request assistance from staff. On the other hand, with the full self-mode POS terminal 20, if there are no customers, the registration information can be sent and processed immediately, and even if there are customers, it is sufficient to simply process the information in order. This is because such problems are unlikely to occur.

In view of the above, the store clerk is informed as to whether or not the POS terminal 20 is preferable as the destination of the registered information, or which one is more preferable in the case where there are multiple destinations of the registered information. As an example, in FIG. 16(A), the outline of the 20-3 checkout button BT13 corresponding to the full-self mode POS terminal 20-3, which is relatively preferable as the destination of registration information, is shown by a solid line, and the destination of registration information is The outline of the 20-2 checkout button BT12 corresponding to the POS terminal 20-2 in the normal mode, which is relatively unfavorable, is indicated by a broken line. Note that the above-mentioned notification by the outline part is just one example, and the store clerk can determine whether or not the POS terminal 20 is the preferred destination for the registered information, or which one is more preferable in the case where there are multiple destinations for the registered information. The notification mode is not limited as long as it can be recognized. For example, if it is relatively undesirable, the background color of the button may be grayed out, or a penalty mark or diagonal line may be added to the entire button. Further, the display size, shape, and display position of the button may be changed depending on whether or not the POS terminal 20 to which the registered information is to be sent is preferable, and the button may contain some information (such as "priority" or "recommended"). You may also attach a badge-like image (such as a badge-like image).

When the POS terminal 20 is displaying the registration screen as shown in FIG. 16(A) on the clerk side display section 210, the small screen SG01 as shown in FIG. 16(B) on the customer side display section 205 is displayed. will be displayed superimposed on the payment screen (deposit screen). Note that on the payment screen (deposit screen) in Figure 15 (B), the total amount was 0 yen because no product was registered, but on the payment screen (deposit screen) in Figure 16 (B), the total amount was 0 yen. is registered, so the total amount is 215.

When the customer inserts 500 yen while the POS terminal 20 is displaying the registration screen shown in FIG. 16(A) on the clerk side display section 210, the POS terminal 20 displays the registration screen shown in FIG. 17(A) on the clerk side display section 210. Display a registration screen like this.

Since the customer has inserted 500 yen, 500 is displayed in the display column HR01 at the top right of the screen in FIG. 17(A). Also, by inserting 500 yen, the payment will be made at the own terminal (POS terminal 20-1), so it will be used when making the payment at other terminals (POS terminal 20-2, POS terminal 20-3). The buttons (20-2 cash register button BT12, 20-3 cash register button BT13, checkout button BT15) are hidden (erased).

When the POS terminal 20 displays a registration screen as shown in FIG. 17(A) on the clerk side display section 210, the POS terminal 20 displays a payment screen (deposit screen) as shown in FIG. 17(B) on the customer side. It is displayed on the display unit 205. Note that the small screen SG01 has been erased because 500 yen has been inserted by the customer.

The POS terminal 20 displays the registration screen of FIG. 17(A) on the clerk side display section 210, and the clerk registers the second item (asparagus) and the third item (nori bento), and the customer If an additional 500 yen is inserted, a registration screen as shown in FIG. 18(A) is displayed on the clerk side display section 210. Since the customer has inserted an additional 500 yen, 1000 is displayed in the display field HR01 at the top right of the screen in FIG. 18(A).

When the POS terminal 20 displays a registration screen as shown in FIG. 18(A) on the clerk side display section 210, the POS terminal 20 displays a payment screen (deposit screen) as shown in FIG. 18(B) on the customer side. It is displayed on the display section 205.

When the clerk operates the subtotal button BT10 from the state where the registration screen of FIG. 18(A) is displayed on the clerk side display section 210, the POS terminal 20 displays the registration screen shown in FIG. As shown, a small screen (small window) SG02 is displayed superimposed on the registration screen, and a payment screen (deposit screen) as shown in FIG. 19(B) is displayed on the customer side display section 205. The small screen SG02 is for notifying the store clerk of payment-related information (total amount, device deposit amount (deposit amount)).

When the customer operates the end (receipt) button BT40 while the customer side display section 205 is displaying the payment screen (deposit screen) shown in FIG. 20(A), a message screen MG1 is displayed superimposed on the registration screen, and a payment screen (change screen) as shown in FIG. 20(B) is displayed on the customer side display section 205. .

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

Although illustrations from FIG. 20 onward are omitted, the POS terminal 20 displays a payment screen similar to that shown in FIG. Display the corresponding message.

In the above explanation, we focus on the overall processing at the POS terminal 20, and assume that no processing is in progress (product not registered, cash not inserted, payment type not selected, gift certificate not registered, customer information not obtained). (state) is referred to as the initial state, but it may also be referred to as the initial state, focusing on a part of the processing. For example, the cash input product registration status (product registered, cash input, payment type not selected, gift certificate not registered, customer information not acquired) is an initial status when focusing on the overall process. However, if we focus only on the state of payment type selection, it can be said that it is in the initial state. Furthermore, if we focus on the two states of product registration and payment type selection, we cannot say that they are initial states, but the two states of payment type selection and gift certificate registration. If we pay attention to this, we can say that this is the initial state.

In the example shown in FIG. 19, when the subtotal key is operated, the POS terminal 20 displays the small screen SG02 superimposed on the registration screen (FIG. 19(A)). When the subtotal key is operated, instead of (switching) to the registration screen, a sub-plan screen that displays the information displayed on the small screen SG02 may be displayed.

(Screen display on POS terminal 20 in full self mode)
Next, the screen display on the POS terminal 20 in full self mode will be explained. 21 and 22 are display examples on the POS terminal 20 in full self mode. Specifically, FIGS. 21(A), 21(B), and 22(A) to 22(F) are display examples on the customer side display section 205 of the POS terminal 20 in full self mode. be.

FIG. 21A shows the display contents of the registration start screen before the start of the registration process. In FIG. 21(A), 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 bottom left of the screen are buttons for switching the display language to English, Chinese, and Korean, respectively. The buttons BT35 to BT37 are displayed on various other screens, but their functions are common.

FIG. 21(B) shows the display contents of the registration screen in a state where the second product (Daifuku mochi) is registered. Note that when the registration start button BT30 is operated on the registration start screen shown in FIG. 15(A), the POS terminal 20-3 displays a registration screen with no products registered yet. For convenience, FIG. 21(B) shows the registration screen after the products (tea, daifuku mochi) have already been registered.

In FIG. 21(B), the image GA01 at the lower left of the screen shows the state (specifically, the normal mode) of the other terminal (POS terminal 20-1). Image GA02 at the bottom left of the screen shows the state (specifically, the normal mode) of the other terminal (POS terminal 20-2). The 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 the product registration. The clerk call button BT33 is a button for calling a clerk. The customer operates the clerk call button BT33 when calling the store clerk (for example, when the store clerk's support is required).

"Vegetables" button BT38 is a button for displaying each vegetable preset key. A button for displaying a preset key such as the "vegetables" button BT38 is, for example, a button displayed for registering a product to which a barcode is not attached. Products to which these barcodes are not attached are assigned to preset keys in advance, for example.

FIG. 22(A) shows the display contents of the payment screen (payment method selection screen) that is displayed when starting the payment process. For example, when the checkout button BT32 is operated on the registration screen (see FIG. 21(B)), the POS terminal 20 displays a payment method selection screen as shown in FIG. 22(A).

FIG. 22(B) shows the display contents of the settlement screen (deposit screen) that is displayed when starting payment in cash. For example, when cash is operated on the payment method selection screen (see FIG. 22(A)), the POS terminal 20 displays a deposit screen as shown in FIG. 22(B).

FIG. 22(C) shows the display contents of the settlement screen (deposit screen) that is displayed when determining the deposit amount. For example, the POS terminal 20 displays a deposit screen as shown in FIG. 22(C) when cash (deposit) equal to or greater than the payment amount (purchase amount) is deposited.

FIG. 22(D) shows the display contents of the payment screen (change screen) that is displayed when changing is released. For example, when the end (receipt) button BT40 is operated on the deposit screen (FIG. 22(C)), the POS terminal 20 displays a change screen as shown in FIG. 22(D).

FIG. 22(E) shows the display contents of the payment screen (receipt screen) that is displayed when change is removed. For example, when change is removed from the outlet of the change machine 209, the POS terminal 20 displays a receipt screen as shown in FIG. 22(E). Note that the POS terminal 20 may install a sensor such as a photo sensor near the takeout port, and determine that change has been removed when the sensor recognizes an object (assuming a customer's hand). FIG. 22(F) is a hibernation screen displayed when in hibernation mode (hibernation state).

Note that after displaying the receipt screen (FIG. 22(E)), the POS terminal 20 displays a registration start screen (FIG. 21(A)). For example, the POS terminal 20 displays a registration start screen after the receipt is removed from the issuing port of the printing unit 213. Note that the POS terminal 20 may include a sensor that can recognize that the receipt has been removed from the issuing port. Additionally, if change is not generated, the change screen (Figure 22 (D)) may not be displayed and the deposit screen (Figure 22 (C)) may be transitioned to the receipt screen (Figure 22 (E)). .

(Screen display when starting next customer registration at POS terminal 20 in full self mode)
Next, a screen display when starting next customer registration on the POS terminal 20 in full self-mode will be described. In the POS terminal 20, when the customer side registration section is registering the product using the customer side scanner section 206 or paying for the product using the change machine 209, the clerk side registration section starts the product registration process. When this happens, the operation mode of the clerk side registration section is switched to the clerk side registration mode. Further, the clerk-side registration unit, which is in the clerk-side registration mode, registers the registered product as the registration information of the next customer's product.

23 and 24 are display examples on the POS terminal 20. Specifically, FIG. 23(A) is a display example on the clerk side display unit 210 of the POS terminal 20 in full self mode, and FIG. 23(B), FIG. 24(A), and FIG. 24(B) are all display examples. This is an example of a display on the clerk side display section 210 of a POS terminal in which the clerk side registration section is in the normal mode and the customer side registration section is in the full self mode.

As shown in FIG. 23(A), on the clerk side display section 210 of the POS terminal 20 in full self mode, in principle, the information displayed on the customer side display section 205 as shown in FIG. 23(A) A screen that is almost the same as the screen (mirror screen) is displayed. By displaying the same screen as the screen on the customer side display section 205 on the clerk side display section 210, in the POS terminal 20 whose operation mode is full self mode, when there is a clerk on the clerk side, the operation mode is in full self mode. Since the screen that the customer is operating himself/herself can be viewed on the clerk side display section 210, it is possible to assist the customer in registering and to easily detect fraud.

Further, the screen displayed on the clerk side display section 210 shown in FIG. 23(A) is different from the screen displayed on the customer side display section 205 shown in FIG. 21(B), in which the next customer registration button BT50 is displayed. They are different in that they are Next customer registration button BT50 is activated when the current customer registers a product or pays for the product at the customer side registration section of the POS terminal 20 in full self mode. This button is used to start the registration process.

Therefore, the registration of the product in the clerk side registration section is started by operating the next customer registration button BT50. Registration of the product at the clerk side registration unit may be started under other conditions. For example, the registration of a product in the store clerk side registration section may be started when the store clerk side scanner section 212 reads a barcode or a store clerk code attached to the product. In addition, to register a product at the clerk side registration section, the bar code or clerk code attached to the product must be entered before payment is made at the card payment section 208 or change machine 209 provided in the customer side registration section. It does not start when the clerk's scanner section 212 reads it, but it starts when the clerk's scanner section 212 reads the bar code or clerk code attached to the product while the product is being paid for. You may also do so. In addition, when a barcode or clerk code attached to the product is read by the clerk side scanner section 212 while the product is being registered in the customer side registration section, the system switches to double scan mode or registers on the clerk side. A selection button may be displayed on the clerk side display section 210 for selecting whether to start registering the product in the department. The selection button may be assigned to the key operation section 211.

FIG. 23(B) shows the contents displayed on the clerk side display section 210 when the next customer registration button BT50 is operated while the current customer is registering a product or paying for the product in the full self mode. It shows. When the next customer registration button BT50 shown in FIG. It is now possible to register products. Therefore, when the next customer registration button BT50 is operated, the registration screen for the normal mode is displayed on the clerk side display section 210.

On the registration screen displayed on the clerk side display section 210, two levels of tabs are displayed: a first tab area T1 and a second tab area T2. The first tab area T1 shows the transaction status of the current customer, and displays the character "1". The second tab area T2 shows the transaction status of the next customer, and the character "2" is displayed. On the screen shown in FIG. 23(B), the second tab area T2 is selected and the transaction status of the next customer is shown. When the first tab area T1 is operated here, the transaction status (mirror screen of the screen displayed on the customer side display section 205) of the current customer who registers the product in the full self mode is displayed.

FIG. 24(A) shows the display contents of the registration screen when registering the next customer's products on the clerk side display section 210. The screen shown in FIG. 24(A) is the same as the registration screen shown in FIG. 16(A) except for the display of the first tab area T1 and the second tab area T2, and the product is registered as the next customer's product. The registered details of the product are displayed. Specifically, the screen shown in FIG. 24A shows a screen in which "canned beer," "asparagus," and "nori bento" are registered.

If the clerk operates the subtotal button BT10 while the clerk side display section 210 is displaying the registration screen of FIG. indicate. When completing the registration process for the next customer, the POS terminal 20 changes the display content on the clerk side display section 210 depending on the payment status of the current customer.

FIG. 24(B) shows the display contents of the registration screen when the registration of the next customer's products on the clerk side display section 210 is completed. When the registration of the next customer is completed (when the subtotal button BT10 is operated), if the payment processing of the current customer is not completed, the POS terminal 20 displays the screen shown in FIG. As shown in , a small screen (small window) and a cashier guidance screen SG11 are displayed superimposed on the registration screen. On the other cashier guidance screen SG11, the total amount of the registered products is entered, and a message such as "Previous customer is currently paying. Would you like to pay at another cash register?" is displayed. This message notifies the current customer (previous customer from the perspective of the next customer) that the payment process has not been completed and urges the customer to pay at another cash register.

A 20-2 register button BT51, a 20-3 register button BT52, and a standby button BT53 are displayed on the other register guidance screen SG11. The 20-2 register button BT51 is a button for specifying the 20-2 register (second POS terminal 20-2). By operating the 20-2 register button BT12, the second POS terminal 20-2 is designated as the terminal to which registration information is to be transmitted. The 20-3 register button BT52 is a button for specifying the 20-3 register (third POS terminal 20-3). By operating the 20-3 cash register button BT52, the third POS terminal 20-3 is designated as the terminal to which registration information is to be transmitted.

The standby button BT53 is a button that is operated when making payment using the own device without transmitting registration information to another cash register. When the standby button BT53 is operable, the current customer is using the payment machine (change machine 209) at the POS terminal 20 of the own device, so the next customer completes the payment process for the previous customer. You will have to wait for payment until then. The standby button BT53 is used, for example, when it appears that the current customer's payment processing is about to end.

The store clerk operates the 20-2 cash register button BT51, the 20-3 cash register button BT52, and the standby button BT53 according to his/her own judgment to guide the next customer to the POS terminal 20 where payment is to be made. Further, the clerk may operate the 20-2 cash register button BT51, the 20-3 cash register button BT52, and the standby button BT53 based on the wishes of the next customer. Note that the other cash register guidance screen SG11 shown in FIG. 24(B) is displayed only when the registration of the next customer's products is completed and the subtotal button BT10 is operated while the current customer is processing payment. The subtotal button BT10 may not be displayed even if the subtotal button BT10 is operated after the current customer's payment processing is completed. Further, when displaying the other cash register guidance screen SG11 on the clerk side display section 210, the images GA02, GA03, etc. may be deleted. Furthermore, the subtotal button BT10 may be deleted after it has been operated.

Note that when the registration process for the next customer is completed (when the subtotal button BT10 is operated), if the current customer's payment process has been completed, the POS terminal 20 will display the small screen shown in FIG. 19(A). The screen (small window) SG02 is displayed on the clerk side display unit 210, superimposed on the registration screen. Further, when the current customer's checkout process is completed while the registration screen shown in FIG. 23(B) is displayed, the display in the first tab area T1 is erased.

FIG. 25 is a flowchart illustrating an example of product registration processing performed by the POS terminal 20. The POS terminal 20 performs product registration processing for the current customer's transaction, and then starts product registration processing for the next customer's transaction during the current customer's transaction or after the current customer's transaction ends. Furthermore, before the start of product registration for the current customer, the operating mode of the POS terminal 20 is the full self mode. When starting a transaction for a next customer during a transaction for the current customer, the clerk side registration section of the POS terminal 20 becomes the normal mode. Note that in this case, the clerk side registration section of the POS terminal 20 may be in a semi-self mode (registration only mode). In addition, the CPU 201 of the POS terminal 20 controls the control means for controlling the switching of operation modes including normal mode and full self mode, and the clerk side registration section when registration is being performed by the customer side registration section or payment is being made by the payment section. Functions as an addition prohibition control means that prohibits the registration information of the next customer's product registered in , from being added to the registration information of the current customer's product that has been registered by the customer side registration department or settled by the payment department. .

Step S101: The POS terminal 20 displays the registration start screen shown in FIG. 21(A) on the customer side display section 205. While the registration start screen is displayed, the POS terminal 20 has not yet started the product registration process for the current customer's transaction, and when the registration start button BT 30 is operated, the product registration process for the current customer's transaction is completed. start processing. Note that the POS terminal 20 may display a mirror screen of the customer side display section 205 on the clerk side display section 210, or may display another screen.
Step S102: The POS terminal 20 determines whether the registration start button BT30 has been pressed. If it is determined that the registration start button BT30 has been pressed, the POS terminal 20 proceeds to step S103, and if it is determined that the registration start button BT30 has not been pressed, the POS terminal 20 repeats the process of step S102.
Step S103: The POS terminal 20 starts the transaction for the current customer and displays the registration screen shown in FIG. 21(B) on the customer side display section 205. The product is registered when the customer operates a button included in the registration screen displayed on the customer side display section 205 or scans the product.
Step S104: The POS terminal 20 displays a next customer registration button on the clerk side display section 210. The POS terminal 20 displays the mirror screen shown in FIG. 23(A) on the clerk side display section 210, and when displaying the mirror screen, also displays the next customer registration button BT50.

Step S105: The POS terminal 20 determines whether the next customer registration button BT50 shown in FIG. 23(A) has been pressed. If it is determined that the next customer registration button BT50 has been pressed, the POS terminal 20 proceeds to step S106 and starts registration processing for the next customer transaction. The registration process for the next customer transaction will be explained later. If it is determined that the next customer registration button BT50 has not been operated, the POS terminal 20 proceeds to step S107.

Step S106: The POS terminal 20 erases the next customer registration button displayed on the clerk side display section 210, and proceeds to step S107.
Step S107: The POS terminal 20 performs a product registration process for the current customer's transaction in the customer side registration section. In the product registration process in the customer's transaction at the customer side registration unit, the POS terminal 20 determines whether there is a scan such as a touch on the customer side display unit 205 or a reading by the customer side scanner unit 206. The POS terminal 20 does not register the product if there is no scan or the like, but registers the product if there is a scan or the like and displays the registered product on the customer side display section 205. In this way, the product registration process in the customer-side registration unit in the current customer's transaction progresses, and new products are additionally registered. Additional registration of the current customer's products is performed in addition to the registration of products in the current customer's transaction. Note that when the POS terminal 20 displays the mirror screen of the customer-side display section 205 on the clerk-side display section 210, the POS terminal 20 also displays the registered product on the clerk-side display section 210.

Step S108: The POS terminal 20 determines whether the checkout button BT32 shown in FIG. 21(B) has been pressed. If it is determined that the checkout button BT32 has been pressed, the POS terminal 20 proceeds to step S109, and if it is determined that the checkout button BT32 has not been pressed, the POS terminal 20 returns to step S105 and presses the next customer registration button. It is determined whether or not the BT 50 has been operated.

Step S109: The POS terminal 20 performs current customer payment processing. In the current customer payment process, the POS terminal 20 displays a small screen regarding the current customer's transactions, and upon accepting payment operations such as inputting a deposit and pressing the cash total button, issues a receipt. In addition, in the current customer settlement process, change may be released according to the deposit or the total amount in the current customer's transaction settlement process. Further, in the current customer payment process, transaction history information (sales data) of the current customer is stored. In this way, the current customer registration process is completed.

Next, registration of products in the next customer's transaction will be explained. When the next customer registration button BT50 is pressed while the product is being registered for the current customer's transaction, the registration process for the next customer's transaction is started. When starting the registration process for the next customer's transaction, the POS terminal 20 allows the registration of the product for the next customer's transaction upon pressing the next customer registration button BT50 in step S105. The next customer registration is performed by the clerk side registration section of the POS terminal 20, and the operation mode of the clerk side registration section of the POS terminal 20 used for next customer registration is the normal mode. For this reason, the registration of the product in the next customer's transaction is performed at the clerk's side registration section.

Step S121: After allowing the next customer to register the product for the transaction, the POS terminal 20 displays a registration screen on the clerk side display section 210.
Step S122: The POS terminal 20 performs product registration processing for the next customer's transaction at the clerk side registration section. The registration process here is performed by the store clerk's operation of the POS terminal 20. In the product registration process for the next customer's transaction in the clerk side registration section, the POS terminal 20 performs scanning, etc., such as touching the clerk side display section 210 by the clerk, operating the key operation section 211, and reading by the clerk side scanner section 212. Determine whether or not there is. The POS terminal 20 does not register the product if there is no scan or the like, but registers the product if there is a scan or the like and displays the registered product on the customer side display section 205. In this way, the product registration process in the store clerk side registration section in the next customer's transaction progresses. Additional registration of products for the next customer is performed in addition to product registration for the next customer's transaction, and additional registration of products for the current customer's transaction is prohibited in addition to product registration for the next customer's transaction.

Step S123: The POS terminal 20 determines whether the subtotal button BT10 shown in FIG. 24(A) has been pressed. If it is determined that the subtotal button BT10 has been pressed, the POS terminal 20 proceeds to step S124. If it is determined that the checkout button BT32 has not been pressed, the POS terminal 20 returns to step S122 and continues the product registration process for the next customer's transaction.
Step S124: The POS terminal 20 determines whether the payment process (step S109) for the current customer's transaction has been completed. If it is determined that the settlement process for the current customer's transaction has been completed, the POS terminal 20 proceeds to step S125; if it is determined that the settlement process for the current customer's transaction has not been completed, the POS terminal 20 proceeds to step S125. Proceed to S126.

Step S125: The POS terminal 20 performs next customer payment processing. In the next customer payment process, the POS terminal 20 displays a small screen on the customer side display section 205 regarding the next customer's transaction, accepts payment operations such as inputting a deposit and pressing the cash button, and issues receipts. conduct. At this time, since the payment process for the current customer (previous customer from the perspective of the next customer) has been completed, the current customer moves away from in front of the customer side display section 205 and the area in front of the customer side display section 205 becomes vacant. ing. The next customer moves in front of the change machine 209 at the POS terminal 20 and performs payment processing. In addition, in the next customer settlement process, change may be released according to the deposit or cash amount in the next customer's transaction settlement process. Further, in the next customer payment processing, transaction history information (sales data) of the next customer is stored.

Step S126: The POS terminal 20 displays a selection means on the clerk side display section 210 to select whether to perform the payment on its own device or on another POS terminal 20. As a selection means, the POS terminal 20 displays, for example, another cash register guidance screen SG11 shown in FIG. 24(B) on the clerk side display section 210. The other register guidance screen SG11 includes other register designation buttons (20-2 register button BT51, 20-3 register button BT52, and standby button BT53).
Step S127: The POS terminal 20 determines whether the other register designation buttons (20-2 register button BT51, 20-3 register button BT52) have been pressed. If it is determined that the other register designation buttons have not been pressed, The POS terminal 20 proceeds to step S128, and if it is determined that the other register designation button has been pressed, the POS terminal 20 proceeds to step S130.

Step S128: If the other register designation buttons (20-2 register button BT51, 20-3 register button BT52 are not pressed, the POS terminal 20 detects the press of the standby button BT53. After pressing , while waiting for the current customer to complete payment, a button for specifying another register may be displayed on the clerk side display section 210 or the customer side display section 205. At this time, the POS terminal 20 , when the other cashier designation button is pressed, the next customer's registration information may be sent to the designated cashier (POS terminal) to cause payment to be made at the designated cash register.
Step S129: The next customer waits for the current customer to complete the payment process. By pressing the standby button BT53, the next customer completes the payment process for the current customer's transaction, and then performs the payment process using the POS terminal 20, which is his own terminal. Therefore, the next customer waits until the payment process of the current customer is completed. After the current customer's payment process is completed, the next customer moves to the front of the change machine 209 at the POS terminal 20 and performs the payment process. In this way, the next customer registration process is completed.
Step S130: The POS terminal 20 transmits the next customer's registration information to the specified cash register (POS terminal) using the communication unit 215 serving as a transmitting means. For example, when a store clerk presses the 20-2 checkout button BT51 shown in FIG. . The store clerk also instructs the customer to perform payment processing using the second POS terminal 20-2. The customer display section 205 of the second POS terminal 20-2 displays the payment screen shown in FIG. 22(A) to assist the customer in payment processing. In this way, the next customer registration process is completed.

In this way, in the above-mentioned POS system 1, when the operation mode is full self-mode, the current customer performs the registration process at the customer side registration department, or when the customer performs the payment process at the payment department, the clerk side registration You can set the department to normal mode and start registering the next customer. Therefore, even if it takes time to register the current customer, registration of the next customer can be started, and products can be registered efficiently.

For example, in Japanese Patent Application Publication No. 2017-37399, registration of a second customer's payment target is started during the registration of a first customer's payment target, and the second customer's payment information is changed from the first customer's payment information. A technique for outputting the data first is also disclosed. However, this product registration device merely switches the customer's destination when sending payment information to the payment device. It is not possible to improve the efficiency of product registration.

Further, Japanese Patent No. 5998740 discloses a technique in which when the operating mode of a POS terminal in a POS system is switched, the operating mode of other POS terminals in the POS system is switched to a different operating mode. However, this POS system makes only a small contribution to improving the efficiency of product registration at a single POS terminal.

In contrast to these technologies, in the above-mentioned POS system 1, when the operation mode of the POS terminal 20 is full self-mode, the current customer performs registration processing at the customer side registration section or payment processing at the payment section. By setting the store clerk's registration section to normal mode and starting the next customer's registration when the customer is in the store, the store clerk can register the next customer's product while the current customer is registering the product himself in full self-mode. be able to. In the POS terminal 20 of the POS system 1, which includes a clerk-side registration section and a customer-side registration section, while a customer is registering a product at the customer-side registration section, if the clerk-side registration section cannot perform the registration work, all customers will be It becomes difficult to streamline product registration. By using the above-mentioned double scan mode, it is possible to register products in the clerk side registration department and the customer side registration department, but since it is only possible to register the current customer, for example, when the current customer is paying During the processing, the product cannot be registered in the clerk side registration section. In this regard, in the above-mentioned POS system 1, when the operation mode is full self-mode and the current customer performs registration processing at the customer side registration section or when the customer performs payment processing at the payment section, the clerk side registration section Since you can start the registration of the next customer in the normal mode, you can register not only the current customer's products but also the next customer's products, and so to speak, work on different transactions (registration work and checkout work) can be done at the same time. This allows the product registration work to be done even while the customer is paying for the product. Therefore, when performing registration processing for all customers, it is possible to efficiently register products.

In addition, in the above-mentioned POS system 1, when registration is performed by the customer side registration department or payment is made by the payment department, the registration information of the next customer's product registered in the clerk side registration department is transferred to the current customer's product registration information. Adding to registered information is prohibited. For example, if the registration information of the next customer's product is added while the current customer is registering or paying for the product, it becomes difficult to identify the purchaser of the registered product, which may cause problems at the time of payment. . In this regard, by prohibiting the addition of the registration information of the next customer's product to the registration information of the current customer's product that has been registered by the customer side registration department or settled by the payment department, the current customer and the next customer It is possible to suppress the mixing of products. Therefore, troubles at the time of payment can be prevented.

In addition, in the above-mentioned POS system 1, the registration information of the next customer's product, which has been registered in the clerk side registration section, is transmitted to other POS terminals 20 (second POS terminal 20-2 or third POS terminal 20-3), It is possible to pay for products at the POS terminal to which registration information has been sent. Therefore, even if the current customer's product registration or payment is taking a long time at the first POS terminal 20-1 whose operation mode is full self-mode, the next customer's product payment can be done at another POS terminal. It can be performed. Therefore, it is possible to improve the efficiency of processing for all customers, and to register products efficiently. Note that the registration information transmitted by the first POS terminal 20-1 is such that the POS terminal that receives the registration information and processes the payment as described above only needs to be equipped with a payment machine that allows the customer to make payment. The POS terminal 20 may be a dedicated payment machine that includes only a payment machine other than the POS terminal 20, or it may be a POS terminal in which a registration section is not provided on at least one of the clerk's side and the customer's side.

(Modified example)
In the above example, when performing the payment process, the receipt is finally output as shown in Figure 22 (E), but the receipt may not be output, or the receipt may be output. The customer may be able to choose whether or not to use the service. If the customer is to be able to select the presence or absence of a receipt, for example, as shown in FIG. 26(A), the customer side display section 205 may display a receipt present button BT61 and a no receipt button BT62. . Note that the customer side display section 205 displays a confirmation button BT63 along with a receipt present button BT61 and a no receipt button BT62. The confirmation button BT63 has the same function as the end (receipt) button BT40 shown in FIG. 22(C), and when the confirmation button BT63 is operated by the customer, the confirmation button BT63 shown in FIG. The message screen MG1 is displayed superimposed on the registration screen, and a payment screen (change screen) as shown in FIG. 20(B) is displayed on the customer side display section 205.

When the customer presses the receipt available button BT61 shown in FIG. 26(A), a receipt is issued together with the receipt at the time of payment. Furthermore, when the customer presses the no-receipt button BT62, the receipt printed on receipt paper is not issued and is saved as an electronic receipt. The electronic receipt is managed as mere journal data and is transmitted from the POS terminal 20 to the store controller 10, for example.

Electronic receipts can be provided to customers as electronic information. For example, if a customer is a member of a store and the customer's address, telephone number, e-mail address of a mobile device, etc. are registered in the store controller 10, an electronic receipt can be sent to the mobile terminal, etc. Good too. When sending an electronic receipt, for example, it may be sent as journal data and formatted into receipt information using an application stored in a mobile device, or it may be converted into receipt information and sent. Good too. By providing electronic receipts and discontinuing issuing receipts printed on receipt paper, it is possible to contribute to reducing consumption of paper resources. In addition to transmitting the electronic receipt to a mobile terminal or the like, for example, a slot may be provided on the customer side of the POS terminal 20 into which a recording medium owned by the customer is inserted, and the electronic receipt may be stored in the storage medium inserted into the slot.

Furthermore, whether or not to display the receipt present button BT61 and the no receipt button BT62 may be determined depending on the settings of the store or the like. For example, as shown in FIG. 26(A), the setting may be made to display both a receipt button BT61 and a no receipt button BT62, or as shown in FIG. 26(B), a no receipt button may be displayed. It may be possible to make settings such that the BT62 is displayed and the receipt button is not displayed. Alternatively, as shown in FIG. 26(C), the setting may be such that both the receipt button and the no receipt button are not displayed.

In addition, in the above example, when the subtotal button BT10 is displayed in the normal mode of the POS terminal 20, the 20-2 cash register button BT12 and the 20-3 cash register button BT13 are displayed, but the subtotal button BT10 is The 20-2 register button BT12 and the 20-3 register button BT13 may not be displayed when they are displayed. In this case, after pressing the subtotal button BT10, the 20-2 register button BT12 and the 20-3 register button BT13 may be displayed. By displaying the 20-2 cash register button BT12 and the 20-3 cash register button BT13 after pressing the subtotal button BT10, it is possible to easily perform payment processing at other POS terminals 20 even in the normal mode.

In addition, in the above example, in the registration only mode of the semi-self mode, the subtotal button BT10 is not displayed, but the subtotal button BT10 is displayed, and the 20-2 cash register button BT12 and the 20-3 cash register button BT13 are not displayed. It's okay. In this case, the 20-2 register button BT12 and the 20-3 register button BT13 may be displayed after the subtotal button BT10 is operated. Furthermore, the 20-2 register button BT12 and the 20-3 register button BT13 may be displayed together with the subtotal button BT10.

Note that the above-described embodiment is an example, and the specific configuration is not limited to the above-described embodiment, and includes designs within a range that does not depart from the gist of the invention.

For example, in the above example, the POS terminal 20 has three types of operation modes (normal mode, full self mode, and semi-self mode), but it may have one or more of these operation modes. . For example, a POS terminal may operate only in normal mode or semi-self mode, may operate in normal mode and full-self mode or semi-self mode, or may operate in semi-self mode and full self-mode. In addition, when operating in semi-self mode, it may be possible to operate only in registration-only mode, only in accounting-only mode, or by switching between both registration-only mode and accounting-only mode. Anything that can be done is fine.

Furthermore, in the above example, the POS terminals 20 included in the POS system 1 each include a clerk-side processing section and a customer-side processing section, and product brain registration is possible in both the clerk-side processing section and the customer-side processing section. Although the POS terminal 20 can perform payment processing for both products registered by its own terminal and products registered by other terminals in the POS system 1, the POS terminal 20 may have other modes. For example, a registration-only POS system may be used, which includes one or both of a clerk-side processing section and a customer-side processing section, and product registration can be performed by either or both of the clerk-side processing section and the customer-side processing section. A POS system may include a POS terminal. Alternatively, the POS terminal may include a POS terminal that can perform payment processing for products registered at at least one of its own terminal and another terminal in the POS system.

Furthermore, in the above example, when the subtotal key is operated, the POS terminal 20 displays the small screen SG02 superimposed on the registration screen (FIG. 10(A)). When a key is operated, a small screen that displays the information displayed on the small screen SG02 may be displayed in place of (switched to) the registration screen.

Note that the mode switching button 211a and the like for switching the operating mode are hardware keys, but instead of or in addition to the hardware keys, the operating mode is switched by a software key displayed on the display section (clerk side display section 210, etc.). You can do it like this. That is, instead of or in addition to the mode switching button 211a, a software key corresponding to the mode switching button 211a may be displayed. The same applies to each button in the case where a number of mode switching buttons corresponding to each operation mode are provided.

Furthermore, in the above example, the POS terminal 20 includes one printing unit 213 that can rotate freely 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 clerk side and a printing unit fixedly facing the customer side) may be provided.

In the above example, when sending registered information to another terminal, the clerk specifies (selects) the terminal to which the registered information is to be sent (destination). may specify only that the registered information is to be sent without specifying the destination terminal. In other words, only the send button may be arranged. In the case where the clerk only specifies that the registered information is to be sent without specifying the destination terminal, the sending terminal selects one destination terminal according to a predetermined priority order and registers it on the selected terminal. Submit information.

Further, an advertisement may be displayed on the customer side display unit 205 when the registration process or the payment process is not being performed on the customer side display unit 205. When displaying an advertisement on the customer side display section 205, the advertisement may be displayed in an appropriate manner. For example, when the operation mode is the normal mode, an advertisement is displayed on the entire customer side display section 205 until product registration is started, and once product registration is started, an advertisement is displayed on the corner of the customer side display section 205. The advertisement may be displayed in a smaller size or the display of the advertisement may be terminated.

Further, when the operation mode is the semi-self mode, an advertisement may be displayed on the customer side display section 205 after the payment process is completed and until the registration information is received from another POS terminal 20. . Thereafter, when the registration information is received, the advertisement may be displayed in a small size in the corner of the customer-side display section 205, or the display of the advertisement may be terminated.

For example, when transmitting registration information from the first POS terminal 20-1 to other terminals (second POS terminal 20-2, third POS terminal 20-3), the above predetermined priority order is set to the third POS terminal 20-3 in full self mode. may be higher than that of the second POS terminal 20-2 in the normal mode (registration information may be sent preferentially to the third POS terminal 20-3 in the full self mode).
