(Outline of each operation mode)
Next, operation modes of the POS terminal 20 will be described. The POS terminal 20 has multiple operating modes. Specifically, the POS terminal 20 has four types of operation modes (normal mode, full self mode, double scan mode, semi self mode). The operation modes described below are the operation modes during normal business (operation modes related to product registration processing and accounting processing). It does not include the maintenance mode for setting work or maintenance work, or the training mode for training newcomers.

5 to 8 are diagrams for explaining the outline of the operation modes of the POS terminal. FIG. 5 is a diagram for explaining the outline of the normal mode. FIG. 5A is a schematic diagram showing the flow of processing (merchandise registration processing, accounting processing) and the actions of people (staff, customers) in the normal mode, and FIG. 4 is a flow chart showing a basic flow of operation;
FIG. 6 is a diagram for explaining the outline of the full-self mode. FIG. 6A is a schematic diagram showing the flow of processing (merchandise registration processing, accounting processing) and the actions of people (customers) in the full self mode, and FIG. 4 is a flow chart showing a basic flow of operation; FIG. 7 is a diagram for explaining the outline of the double scan mode.
FIG. 7A is a schematic diagram showing the flow of processing (merchandise registration processing, accounting processing) and the actions of people (customers) in the double scan mode, and FIG. 4 is a flow chart showing a basic flow of operation; FIG. 8 is a diagram for explaining the outline of the semi-self mode.
FIG. 8(A) is a schematic diagram showing the flow of processing (product registration processing, accounting processing) and the actions of people (customers) in the semi-self mode, and FIGS. 8(B) and 8(C) in the semi-self mode 4 is a flowchart showing a basic flow of operations of the POS terminal 20;

In the following description, the mode in which the POS terminal 20 executes product registration processing is the registration mode, and the mode in which the POS terminal 20 executes the settlement processing is the accounting mode (or settlement mode).

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

In the normal mode, the clerk registers the purchased product of the customer on the clerk side (clerk side scanner section 212, clerk side display section 210, key operation section 211). In other words, the POS terminal 20 executes the registration process of the purchased product according to the operation of the store clerk (the operation of the store clerk side scanner unit 212, the store clerk side display unit 210, the key operation unit 211, etc.) (upper part of FIG. 5A). .

When the registration process by the clerk is completed, the customer confirms the total amount of purchased commodities on the clerk-side display unit 210, inserts money into the change machine 209, or operates the card payment unit 208 to settle the account (FIG. 5). (A) lower row). That is, the POS terminal 20 executes the settlement process according to the customer's operation (insertion of money into the change machine 209, operation of the card settlement unit 208) (lower part of FIG. 5A).

That is, in the normal mode, as shown in FIG. 5B, the product is first scanned by the store clerk, for example, by the store clerk scanner unit 212 (step S10: YES), and the product is registered (step S11). After pressing the subtotal key (for example, the subtotal key displayed on the store clerk side display unit 210 or the subtotal key arranged on the key operation unit 211, etc.) (step S30: YES), for example, the change machine 209 is performed (step S50), and the process is completed.

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

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

In addition, when there is change, the POS terminal 20 controls the dispensation of change or bills by the change machine 209 in order to prevent forgetting to take the change, and a sensor or the like detects that the customer has removed the change or bills. , the printing unit 213 is controlled to issue a receipt. The same applies to other operation modes. As described above, in the normal mode (the same applies to the double scan mode), there may or may not be a store clerk in front of the customer who receives the change. (That is, the payment of change/change and the receipt may be issued at the same time, or the receipt may be issued first). Further, the timing of paying out change/tills and issuing receipts may be controlled according to the current operation mode and the presence/absence of a clerk (for example, the presence/absence of a clerk is recognized by a sensor).

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

In the case of the full self mode, the customer registers the purchased product on the customer side (customer side scanner section 206, customer side display section 205). That is, the POS terminal 20 executes registration processing of the purchased product by the customer's operation (scanning by the customer-side scanner unit 206, touching the customer-side display unit 205) (upper part of FIG. 6A).

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

That is, in the full-self mode, as shown in FIG. 6B, the product is scanned by the customer-side scanner unit 206 on the customer side (step S20: YES), and the product is registered (step S21). After the registration completion key (for example, the registration completion key displayed on the customer-side display unit 205) is pressed (step S40: YES), the customer's account is settled by, for example, the change machine 209 (step S50), and processing is performed. is completed.

In the full-self mode, as described above, the customer side executes both the registration process and the settlement process, but this does not mean that the store clerk cannot do anything. That is, even when the POS terminal 20 is operating in the full self mode, the clerk-side scanner unit 212 can scan the clerk code. Further, the POS terminal 20 can display various information (for example, the list described in FIG. 15) on the clerk-side display section 210 even when operating in the full-self mode.

(double scan mode)
The double scan mode, as shown in FIG. 7A, is an operation mode in which registration processing is executed on both the store clerk side and the customer side, and settlement processing is executed on the customer side. That is, as shown in FIG. 7B, in the case of the double scan mode, both the clerk side and the customer side are in the registration mode, and the customer side is in the checkout mode. In other words, the POS terminal 20 operates in the registration accounting mode from the registration process to the settlement process as a whole.

In the case of the double scan mode, the clerk registers the purchased product on the clerk side (clerk side scanner unit 212, clerk side display unit 210, key operation unit 211), and the customer registers the purchased product on the customer side (customer side scanner unit 211). 206, customer-side display unit 205). That is, the POS terminal 20 can be operated by a clerk (scanning by the clerk-side scanner unit 212, touching the clerk-side display unit 210, pressing the key operation unit 211, etc.) and by a customer (customer-side scanner unit 206). , and touch on the customer-side display unit 205), the registration processing of the purchased product is executed (upper part of FIG. 7A).

When the registration process is completed, the customer confirms the total amount of purchased products on the customer-side display unit 205, inserts money into the change machine 209, or operates the card settlement unit 208 to settle the account (Fig. 7 (A) ) below). That is, the POS terminal 20 executes the settlement process according to the customer's operation (insertion of money into the change machine 209, operation of the card settlement unit 208) (lower part of FIG. 7A).

That is, in the double scan mode, products are first registered on the store clerk side and the customer side. For example, as shown in FIG. 7B, by scanning the store clerk side scanner unit 212 (step S10: YES), goods are registered (step S11), and by scanning the customer side scanner unit 206 (step S20: YES), the product is registered (step S21). A subtotal key (for example, a subtotal key displayed on the clerk-side display unit 210 or a subtotal key arranged on the key operation unit 211) or a registration completion key (for example, a registration completion key displayed on the customer-side display unit 205) After the completion key, etc.) is pressed (step S41: YES), on the customer side, the payment is made by, for example, the change dispenser 209 (step S50), and the process is completed.

The store clerk may wait until the customer completes the payment (until the customer obtains change or a receipt), or may register the next customer's purchased product. In other words, the POS terminal 20 can register the purchased product of the next customer during the checkout process (lower part of FIG. 7A). Also, the clerk may be absent during the payment by the customer (lower part of FIG. 7(A)). In other words, the reception of the customer may be finished during the payment of the customer.

(Semi-self mode)
The semi-self mode is an operation mode using two or more POS terminals 20, and as shown in FIG. The registration process is performed on the customer side, and the customer side of another POS terminal 20 (one of the second POS terminal 20-2 and the third POS terminal 20-3 in the example of FIG. 8) performs the settlement process. This is the operation mode to execute. That is, in the case of the semi-self mode, one or more terminals (in the example of FIG. 8, one of the first POS terminal 20-1 as shown in FIG. In the example of (2), as shown in FIG. 8C, the second POS terminal 20-2 and the third POS terminal 20-3) are in the checkout mode.

In the semi-self mode, the clerk registers the purchased product of the customer at the POS terminal 20 in the registration-only mode on the clerk side (clerk side scanner section 212, clerk side display section 210, key operation section 211). In other words, the POS terminal 20 executes the registration process of the purchased product according to the operation of the store clerk (the operation of the store clerk side scanner unit 212, the store clerk side display unit 210, the key operation unit 211, etc.) (upper part of FIG. 8A). .

When the registration processing by the clerk is completed, the customer moves to the POS terminal 20 in the checkout-only mode, confirms the total amount of purchased commodities on the clerk-side display unit 210, inserts money into the change machine 209, or performs card payment. Operate the unit 208 to settle (lower part of FIG. 8(A)). In other words, the POS terminal 20 executes settlement processing according to the customer's operation (insertion of money into the change machine 209, operation of the card payment unit 208) (lower part of FIG. 8A).

When the registration processing is completed at the POS terminal 20 in registration-only mode (the first POS terminal 20-1 in the example of FIG. 8), the customer transfers from the POS terminal 20 in registration-only mode to the POS terminal 20 in accounting-only mode (in the example of FIG. 8). In the example, it moves to the second POS terminal 20-2), but the destination POS terminal 20 does not have information necessary for settlement processing (registration information generated at the first POS terminal 20-1 in the registration-only mode). supplied.

The destination POS terminal 20 (of the POS terminals 20 in accounting-only mode, the POS terminal 20 that executes the settlement process) may be specified in the POS terminal 20 in registration-only mode. Alternatively, the POS terminal 20 in registration-only mode issues a medium (a medium on which a barcode or the like for obtaining information necessary for settlement processing is printed), and the POS terminal 20 in accounting-only mode that reads the medium is used. It may be the POS terminal 20 at the destination.

In other words, in the semi-self mode, the product is first registered by the clerk of the POS terminal 20 (the first POS terminal 20-1) in the registration-only mode. For example, as shown in FIG. 8B, products are registered (step S11) by scanning with the clerk side scanner unit 212 (step S10: YES). After pressing the subtotal key (for example, the subtotal key displayed on the clerk-side display unit 210 or the subtotal key arranged on the key operation unit 211) (step S30: YES), for example, the POS terminal 20 in accounting mode ( (either one of the second POS terminal 20-2 and the third POS terminal 20-3) is designated (step S31: YES), the registration information is transmitted to the designated POS terminal 20 (step S32), and the registration-only mode is entered. , the processing in the POS terminal 20 is completed.

Subsequently, as shown in FIG. 8C, after receiving the registration information (step S49: YES), the POS terminal 20 in accounting-only mode (that is, the POS terminal 20 specified by the POS terminal 20 in registration-only mode) In the case of the customer, the payment is made by, for example, the change machine 209 (step S50), and the processing at the POS terminal 20 in the payment-only mode is completed.

After transmitting the registration information, the store clerk can register the next customer's purchased product (lower part of FIG. 8(A)). Also, the clerk may be absent after transmitting the registration information (lower part of FIG. 8(A)). Alternatively, the registration-only mode may not be provided. In other words, it is sufficient that the registration information can always be specified to other POS terminals 20 in the normal mode as in the registration-only mode. There is no need to disable the transmission function in normal mode. In this case, in the normal mode, the store clerk executes the registration process as described above, and the customer of the own terminal executes the settlement process using the registration information generated in the registration process (see FIG. 5). ), the store clerk executes registration processing, and transmits the registration information generated in the registration processing to another terminal (other terminal capable of executing settlement processing, for example, another POS terminal 20) (via LAN 11 and send it directly to another terminal, or send it to another terminal via the store controller 10 or a monitoring terminal (not shown); hereinafter the same), and code ( A barcode, two-dimensional code, etc.), printing it on a medium, and issuing it as an accounting ticket can also be executed. In other words, the POS terminal 20 in the normal mode has a function of registering products on its own terminal and paying for it on its own terminal, as well as a function for registering products on its own terminal and paying for it on another terminal. Further, the POS terminal 20 in normal mode has a function of registering a product on its own terminal and paying for it on another terminal, like the POS terminal 20 in semi-self mode (registration-only mode). The POS terminal 20 in normal mode may also have a function of paying for products registered on another terminal, like the POS terminal 20 in semi-self mode (accounting mode). That is, the POS terminal 20 in full-self mode and the POS terminal 20 in normal mode receive registration information from other terminals (the POS terminal 20 in semi-self mode (registration-only mode), the POS terminal 20 in normal mode, etc.). reading the accounting ticket) and executing the settlement process.

(Notification of operation mode)
The POS terminal 20 notifies the current operating mode. For example, the current operation mode may be displayed on the store clerk's display unit 210 . Specifically, a screen having an operation mode display column may be displayed on the clerk-side display unit 210, and the current operation mode may be displayed in the operation mode display column on the screen. Also, a screen on which an image corresponding to each operation mode (for example, a button-like image) is arranged is displayed on the clerk's side display unit 210, and an image corresponding to the current operation mode is displayed on the screen. It may be displayed in a display manner different from that of the non-corresponding image (for example, in a display manner that is more conspicuous than the display manners of other images). Note that the customer-side display unit 205 may similarly display the operation mode.

Also, the POS terminal 20 may notify information according to the current operation mode. For example, the customer-side display unit 205 may display a message corresponding to the current operation mode. Specifically, if the current operation mode is full self mode, for example, when the customer is waiting, the customer himself/herself will be asked to register the product (message such as "Please scan the customer"). It may be displayed on the customer-side display unit 205 (for example, scroll display in large characters).

(Transition of operation mode)
Next, transition (switching) of the operation mode of the POS terminal 20 will be described. The POS terminal 20 changes the operation mode according to an explicit mode change operation (input on the operation mode setting screen, operation of the operation mode setting button, etc.) by the clerk. The operation mode is switched by switching means in the CPU 201 . In addition, the POS terminal 20 changes the operation mode according to another operation (for example, reading a salesclerk code, etc.) other than the explicit mode switching operation by the salesclerk. In addition, the POS terminal 20 can be set under certain conditions that are not dependent on the operation of a store clerk (conditions related to time such as elapsed time and predetermined time (schedule), conditions related to transmission/reception of information such as instructions to/from other terminals, etc.). ), the operation mode is changed.

9 and 10 are diagrams for explaining an example of operation mode transition. FIG. 9A is a flowchart showing the flow of transition from normal mode to full self mode. FIG. 9B is a flow chart showing the flow of transition from full self mode to double scan mode. FIG. 10A is a flowchart showing the flow of transition from normal mode to semi-self mode (registration-only mode). FIG. 10B is a flow chart showing the flow of transition from the normal mode to the semi-self mode (accounting mode).

(Transition from normal mode to full self mode)
The flowchart of FIG. 9A starts when the POS terminal 20 (normal mode) is not in use (that is, when neither the store clerk nor the customer uses it).

Step S100: Start counting non-use time.
Step S101: Judge whether or not the store clerk or customer has started to use the product. If the use has not started, the process proceeds to step S102. When the use is started, the process proceeds to step S104.

Step S102: Determine whether or not the non-use time has passed a predetermined time (for example, preset 10 minutes). If the predetermined time has passed, the process proceeds to step S103. If the predetermined time has not elapsed, the process returns to step S101.
Step S103: Change the operation mode from the normal mode to the full self mode.
Step S104: Terminate the clocking of non-use time. Then, the flowchart of FIG. 9A ends.

In addition, when the shift to the full-self mode is made, the clerk may be notified of the shift to the full-self mode (for example, information indicating that there are undelivered products may be transmitted to the terminal carried by the clerk). . Further, when shifting to the full self mode, the customer side display section 205 may display a message instructing or requesting the customer to perform self registration.

Note that FIG. 9A shows the flow regarding the transition from the normal mode to the full self mode, and the transition from the double scan mode to the full self mode is similar to the flow of FIG. may be

(Transition from full self mode to double scan mode)
The flowchart of FIG. 9B always starts (regularly at very short time intervals) in the POS terminal 20 (full self mode).

Step S110: It is determined whether or not the clerk-side scanner unit 212 has read the clerk code. If the store clerk code is read, the process proceeds to step S111. If the store clerk code has not been read, the flow chart of FIG. 9B ends.

Step S111: Transition the operation mode from the full self mode to the double scan mode. Then, the flowchart of FIG. 9B ends.

(Transition from normal mode to semi-self mode (registration-only mode))
The flowchart of FIG. 10A always starts (regularly at very short time intervals) in the POS terminal 20 (normal mode).

Step S120: It is determined whether or not there is an operation to declare a shift to the semi-self mode (registration-only mode). For example, a button for declaring a transition to the semi-self mode (registration-only mode) may be displayed on the clerk-side display unit 210, and whether or not the button has been pressed (touched) may be determined. If there is an operation, the process proceeds to step S121. If there is no operation, the flow chart of FIG. 10(A) ends.

Step S121: It is determined whether there is another POS terminal 20 operating in the semi-self mode in the POS system 1 or not. As described above, in the case of the semi-self mode, at least one POS terminal 20 in the registration-only mode and one or more POS terminals 20 in the accounting-only mode are required. In this case, it is determined whether one of the second POS terminal 20-2 and the third POS terminal 20-3 operates in semi-self mode (registration-only mode) and the other operates in semi-self mode (accounting-only mode). . If there is no other POS terminal 20 operating in the semi-self mode, the process proceeds to step S122.
If there is another POS terminal 20 operating in the semi-self mode, the process proceeds to step S124.

Step S122: It is determined whether or not another POS terminal 20 to be shifted to the semi-self mode (accounting mode) has been specified. If there is designation, the process proceeds to step S123. If there is no designation, the process of step S122 is repeated.
Step S123: An instruction to shift to the semi-self mode (accounting mode) is transmitted to the designated other POS terminal 20 .

Step S124: Determine whether processing is in progress. If it is not being processed, the process proceeds to step S125. If the processing is in progress, the processing of step S124 is repeated.
Step S125: The operation mode is shifted from the normal mode to the semi-self mode (registration-only mode). Then, the flowchart of FIG. 10A ends.

Note that the operation of step S120 is performed when there is no other POS terminal 20 already operating in the semi-self mode and when there is no other POS terminal 20 capable of shifting to the semi-self mode. should not be allowed.

(Transition from normal mode to semi-self mode (accounting mode))
The flowchart of FIG. 10B always starts (regularly at very short time intervals) in the POS terminal 20 (normal mode).

Step S130: Determine whether or not an instruction to shift to the semi-self mode (accounting mode) has been received. When the transfer instruction is received, the process proceeds to step S131. If no transfer instruction has been received, the flow chart of FIG. 10B ends.

Step S131: Determine whether processing is in progress. If not in process, the process proceeds to step S132. If it is in process, the process of step S131 is repeated.
Step S132: The operation mode is shifted from the normal mode to the semi-self mode (accounting exclusive mode). Then, the flowchart of FIG. 10B ends.

FIG. 10(B) shows the flow of transition from normal mode to semi-self mode (accounting mode). 10(B) flow may be the same. In addition, apart from the shift instruction, in the full self mode, if registration information to be processed by the own device is detected, if it is waiting, it will immediately switch to the checkout mode, and if another customer is operating a transaction, the transaction will be completed. After finishing, you may switch to accounting-only mode. In other words, the migration instruction can also be determined based on detection (reception) of registration information. Furthermore, the shift instruction may be given by operating another information terminal such as a mobile terminal such as a smart phone owned by a store clerk or a mobile terminal used for inventory of products displayed in a store.

(Display in full self mode)
Next, the display of the POS terminal 20 in the full self mode will be described with reference to FIGS. 11 and 12. FIG. 11 and 12 are display examples of the POS terminal 20 in full self mode.

FIG. 11A is a display example of a registration start screen displayed on the customer-side display section 205 of the POS terminal 20 in full self mode. In FIG. 11A, a registration start button BT30 on the right side of the screen is a button for instructing the start of product registration. The customer performs an operation (for example, a touch operation) on the registration start button BT30 before starting product registration. Buttons BT35 to BT37 at the lower left of the screen are buttons for switching the display language to English, Chinese, and Korean, respectively. In the illustrated example, Japanese is selected, so buttons for switching to English, Chinese, and Korean are displayed. For example, when English is selected, the registration start screen in English appears. As a result, buttons for switching between Japanese, Chinese, and Korean are displayed.

When the customer operates the registration start button BT30, the POS terminal 20 shifts to the registration mode, and the display on the customer-side display section 205 changes from the registration start screen to the registration screen.

FIG. 11B is a display example of a registration screen displayed on the customer-side display section 205 of the POS terminal 20 in full self mode. In the illustrated example, on the right side of the registration screen, registered product names, unit prices, the number of registered products (the number of items purchased), and the total amount are displayed as the registration contents. Here, the registered contents of a scene in which two products (pear and apple) are registered are displayed. Note that immediately after the registration start button BT30 is operated on the registration start screen shown in FIG. 11(A) to shift to the registration screen, a registration screen in which no products have been registered yet (registration screen in the initial state). is displayed, but for convenience of explanation, FIG. 11B shows an example of the registration screen after the product has already been registered.

A checkout button BT32 at the bottom right of the screen is a button for instructing the end of product registration. When the customer operates the checkout button BT32 after completing product registration, the POS terminal 20 shifts to checkout mode and executes checkout processing. The clerk call button BT33 is a button for calling a clerk. The customer operates the clerk call button BT33 when calling a clerk (for example, when the clerk's support is required). When the customer operates the clerk call button BT33, for example, the mobile terminal carried by the clerk is notified, and the mobile terminal outputs sound or vibrates. Further, when the customer operates the clerk call button BT33, a predetermined lamp (an indicator lamp such as a sign pole) installed in the store may be turned on.

Buttons BT35 to BT37 are buttons for switching the display language to English, Chinese, and Korean, respectively, as described above. Also, the "vegetables" button BT38 is a button for registering a product (here, vegetables) not attached with a barcode from a preset key. For example, when the customer operates the "vegetables" button BT38, a preset screen is displayed in which each vegetable can be registered by operating a preset key. In the illustrated example, only the "Vegetables" button BT38 is illustrated, but the "Vegetables" button BT38 is also used as a button for registering arbitrary products such as meat, fresh fish, side dishes, bread, etc. from preset keys. can be displayed instead of or in addition to note that. The setting of the preset key is performed in advance at the POS terminal 20 by a store clerk or the like.

When the customer operates the checkout button BT32, the POS terminal 20 shifts to the checkout mode, and the display on the customer-side display section 205 changes from the registration screen to the checkout screen.

FIG. 12 is a display example of a settlement screen displayed on the customer-side display section 205 of the POS terminal 20 in full self mode. FIG. 12A shows a settlement screen (payment method selection screen) displayed when starting settlement processing. For example, the POS terminal 20 displays a payment method selection screen as shown in FIG. 12(A) when the checkout button BT32 is operated on the registration screen (see FIG. 13(B)). The payment method selection screen shown in the figure displays the total payment amount (here, 240 yen), payment method options, and the like. As payment method options, cash, credit, electronic money, etc. are displayed as selectable operation buttons.

FIG. 12B is a settlement screen (deposit screen) displayed when starting payment in cash. For example, the POS terminal 20 displays a deposit screen as shown in FIG. 12(B) when cash is selected on the payment method selection screen (see FIG. 12(A)). In the illustrated deposit screen, an image showing guidance on where to deposit money is displayed on the left side of the screen, and the payment amount (here, 240 yen), the deposited amount (deposit amount), etc. are displayed on the right side of the screen. be done. FIG. 12(C) is a settlement screen (payment determination screen) displayed when determining the deposit amount. For example, the POS terminal 20 displays a payment determination screen as shown in FIG. In the illustrated deposit determination screen, the payment amount (here, 240 yen), the deposited amount (here, 250 yen), change (here, 10 yen), etc. are displayed on the right side of the screen. On the left side of the screen, a guide for determining the deposit amount (here, "If you agree, press the end button") is displayed. The end (receipt) button BT40 is a button operated by the customer when determining the deposit amount. When the customer operates the end (receipt) button BT40, the POS terminal 20 executes settlement processing based on the payment amount (here, 240 yen) and the deposit amount (here, 250 yen).

FIG. 12D is a settlement screen (change screen) displayed when the change is released. For example, the POS terminal 20 displays a change screen as shown in FIG. 12(D) when the end (receipt) button BT40 is operated on the deposit determination screen (FIG. 12(C)). On the change screen shown in the figure, an image is displayed on the left side of the screen to prompt the user to receive the change, and on the right side of the screen, the payment amount (here, 240 yen) and the inserted amount (deposit amount; here, 250 yen) are displayed. yen), change (here, 10 yen), etc. are displayed.

FIG. 12(E) is a settlement screen (receipt screen) displayed when change is removed. For example, the POS terminal 20 displays a receipt screen as shown in FIG. Note that the POS terminal 20 may be provided with a sensor such as a photo sensor near the outlet, and may determine that the change has been removed when the sensor recognizes an object (assuming the customer's hand). Furthermore, it may have a function to prevent forgetting to take the change by printing a receipt after detecting that the change has been taken.

FIG. 12F shows a sleep screen displayed when the POS terminal 20 is in a sleep state. In other words, the POS terminal 20 is in the sleep mode (hibernate state), and displays the sleep screen as shown in FIG. 12(F) when it is in the sleep mode.

The POS terminal 20 displays a registration start screen (FIG. 11A) after displaying the receipt screen (FIG. 12E). For example, the POS terminal 20 displays the registration start screen after the receipt is removed from the issuing port of the printing unit 213 . The POS terminal 20 may have a sensor capable of recognizing that the receipt has been removed from the issuing port.

In addition, when the amount of deposit and the amount of deposit are equal and no change is generated, the change screen (FIG. 12(D)) is not displayed, and the receipt screen (FIG. 12(E) is displayed instead of the deposit screen (FIG. 12(C)). )).

In this way, in the full self mode, when the customer registers and settles the product to be purchased, the POS terminal 20 displays the registration start screen and the registration screen shown in FIGS. , the customer-side display unit 205 displays a settlement screen and the like. In addition, the POS terminal 20 causes the store clerk side display section 210 to display the same display content as the display content displayed on the customer side display section 205 . For example, the POS terminal 20 causes the store clerk side display section 210 to display the same screen as that of the customer side display section 205 (so-called mirror display, mirroring display). Note that displaying the same display content is not limited to displaying exactly the same screen, but includes a partial difference in display content, layout, and the like. For example, in the case of the registration screen, the contents essential for the registration operation (for example, in FIG. button BT38, checkout button BT32, etc.) are displayed on both display units, even if at least part of the other display contents are different, the same display contents may be included in the display. .

(Recalling registration information in semi-self mode)
In the semi-self mode, when registration processing is performed at the POS terminal 20, for example, the first POS terminal 20-1, and settlement processing is performed at the designated POS terminal 20, for example, the second POS terminal 20-2, the first POS terminal 20 -1 transmits the registration information to the second POS terminal 20-2. In the semi-self mode, the registration information transmitted from the first POS terminal 20-1 to the second POS terminal 20-2 can be recalled to the first POS terminal 20-1. Recalling the registration information means that, after sending the registration information to the POS terminal (second POS terminal 20-2), the POS terminal (second POS terminal 20-2) suspends the settlement processing to be executed based on the registration information, or It is to cancel and return the transmitted registration information to the POS terminal (first POS terminal 20-1). Recall generally corresponds to the case of correcting registered information, such as canceling a product registered at a POS terminal (first POS terminal 20-1), or additionally registering a product for additional purchase. is done. Correction of registered information includes, specifically, addition of merchandise, correction of quantity, deletion, discount operation based on privilege, input of member identification information, and the like.

Recalling registration information is, for example, when a customer realizes that he/she left his/her wallet in the car after completing the registration process, and returns to retrieve the wallet, or when the customer does not have enough money to find his/her family. etc. After the recall operation, the second POS terminal 20-2 is ready to perform other operations. Alternatively, the operation may be suspended, the corrected registration information may be received again, and the settlement process may be performed. In the first POS terminal 20-1, the recalled registration information can be put on hold and another customer's merchandise can be registered.

(Display of clerk-side display unit 210 in first POS terminal 20-1)
13 and 14, the display of the store clerk side display unit 210 in the POS terminal 20 (first POS terminal 20-1) when registering a product, sending registration information, and recalling the sent registration information will be described below. do. 13 and 14 are display examples of the clerk's side display section of the first POS terminal 20-1. 13 and 14, the first POS terminal 20-1 is in the semi-self mode registration only mode, and the second POS terminal 20-2 is in the semi-self mode accounting only mode. It is also assumed that the third POS terminal 20-3 is in full self mode. It is also assumed that registration processing is performed at the first POS terminal 20-1 and settlement processing is about to be performed at the second POS terminal 20-2. After recalling the registration information at the first POS terminal 20-1, the first POS terminal 20-1 shifts to the normal mode, and settlement processing is performed at the first POS terminal 20-1. The second POS terminal 20-2 shifts to full self mode. The second POS terminal 20-2 detects the return of the registration information (transmitted to the first POS terminal 20-1), and shifts to the full self mode when detecting the return of the registration information.

FIG. 13 is a display example of a registration screen displayed on the clerk-side display section 210 of the first POS terminal 20-1. Specifically, FIG. 13 shows the display contents of the registration screen when the second product (asparagus) is registered. The registration screen is displayed, for example, after a store clerk reads a bar code (product code, etc.) attached to a product and registration processing is started.

The registration screen displays a sheet (merchandise registration sheet) indicating the merchandise registration contents corresponding to each transaction. The product registration sheet is provided with tabs (regions) (product registration tabs (regions): an example of index regions). In FIG. 13, one product registration tab (area) TAB-1 is displayed. The product registration tab (area) TAB-1 displays a design of an arbitrary animal (here, "cat").

In FIG. 13, the lower left image GA01 of the product registration sheet to which the product registration tab (area) TAB-1 of "cat" is attached shows the state of the No. 2 register (the second POS terminal 20-2 in FIG. 1). . Image GA02 at the bottom left of the product registration sheet shows the state of No. 3 cashier (the third POS terminal 20-3 in FIG. 1).

A subtotal button BT10 at the lower right of the product registration sheet is a button for instructing the end of product registration. The store clerk operates (touches) the subtotal button BT10 after completing product registration. The pause button BT11 is a button for pausing the own terminal (first POS terminal 20-1). The store clerk operates the pause button BT11 when leaving the own terminal (for example, when going to look for a product, when not using the terminal for a while, etc.).

FIG. 14 is a display example of a small plan screen displayed on the clerk-side display section 210 of the first POS terminal 20-1. Specifically, FIG. 14 shows the display contents of the sub-plan screen in the scene following the scene in FIG. 13 (the scene after the subtotal button BT10 is operated).

In FIG. 14, the cash total button BT20 is a button having the same function as the end (receipt) button BT40 that the customer presses after depositing money into the change bill machine. When the customer is confused about the operation at the timing of pressing the end (receipt) button BT40, the clerk presses the cash total button BT20 on behalf of the customer, which is the same as the case where the end (receipt) button BT40 is operated. For example, change is dispensed from a change bill machine or a receipt is issued.

The first register button BT21 is a button for designating the No. 2 register (the second POS terminal 20-2 in FIG. 1). When the clerk designates the second POS terminal 20-2 as the terminal for executing the settlement process, the clerk operates the first register button BT21. The display of "(settlement)" displayed on the first checkout button BT21 indicates that the operation mode of the terminal (second POS terminal 20-2) corresponding to the first checkout button BT21 is the checkout mode of the semi-self mode. It is represented.

When accepting the operation of the first register button BT21, the first POS terminal 20-1 transmits registration information to the No. 2 register (second POS terminal 20-2).

The second register button BT22 is a button for designating the No. 3 register (third POS terminal 20-3 in FIG. 1). When the clerk designates the third POS terminal 20-3 as the terminal for executing the settlement process, the clerk operates the second register button BT22. The "(full)" indicated on the second checkout button BT22 indicates that the operation mode of the terminal (third POS terminal 20-3) corresponding to the second checkout button BT22 is the full self mode. be. The dashed line of the second register button BT22 indicates that the button (second register button BT22) is displayed in a display mode (for example, grayed-down) indicating that the operation of the button (second register button BT22) is not valid.

In the example shown in FIG. 14, the operation of the second register button BT22 is not valid, but if the operation of the second register button BT22 is valid and the operation of the second register button BT22 is accepted, The first POS terminal 20-1 transmits registration information to the No. 3 register (third POS terminal 20-3). By operating the first register button BT21 to transmit the registration information to the second POS terminal 20-2, the registration processing of one transaction in the first POS terminal 20-1 is completed. In addition, since the send button is always displayed during product registration and other device statuses are displayed, it is possible to flexibly specify the selection of the device for which settlement processing is to be performed depending on the situation. In FIG. 14, the display positions of the first checkout button BT21 and the second checkout button BT22 are different from the display positions of the images GA01 and GA02. A first checkout button BT21 and a second checkout button BT22 may be displayed at each position.

The accounting coupon button BT25 is a button for causing the printing unit 113 to issue an accounting coupon. The store clerk operates the accounting coupon button BT25 when the POS terminal 20 that has read the accounting coupon executes the settlement processing. By operating the checkout button BT25, the registration processing for one transaction in the first POS terminal 20-1 is completed.

Information necessary for carrying out settlement processing is coded and printed on the accounting ticket. For example, on the accounting ticket, the registration information itself used for settlement processing may be printed as a QR code (registered trademark), or information for specifying the registration information used for settlement processing (for example, transaction identification information, etc.) may be barcoded and printed.

In the aspect of issuing an accounting coupon printed with the above QR code, the POS terminal 20 (second POS terminal 20-2 or third POS terminal 20-3) that reads the accounting coupon (QR code) reads, for example, Settlement processing is executed using the registration information obtained from the QR code. In addition, in the aspect of issuing an accounting ticket printed with the barcode, the POS terminal 20 (second POS terminal 20-2 or third POS terminal 20-3) that reads the accounting ticket (barcode) reads, for example, The terminal (first POS terminal 20-1) that issued the accounting coupon (first POS terminal 20-1) or the By transmitting the registration information from the terminal that issued the accounting ticket to the terminal that acquired the registration information (for example, the store controller 30), the registration information is received from the terminal that transmitted the registration information acquisition request, and settlement processing is executed. In other words, in the mode of issuing an accounting coupon printed with the barcode, the terminal (first POS terminal 20-1) that issued the accounting coupon or the terminal that issued the accounting coupon acquires the registration information. When the terminal (store controller 30, etc.) that received the registration information acquisition request transmitted from the POS terminal 20 (the second POS terminal 20-2 or the third POS terminal 20-3) that read the accounting ticket, the registration information The registration information specified by the acquisition request is transmitted to the sender of the registration information acquisition request (registration information requester).

The issued accounting ticket is handed to the customer by the clerk. After that, the customer moves to the POS terminal 20 (first POS terminal 20-1 or second POS terminal 20-2), and the POS terminal 20 (customer-side scanner unit 206) reads the code on the checkout ticket. Based on this, the POS terminal 20 executes the settlement process.

The registration screen button BT26 is a button for returning the screen from the subplan screen to the registration screen. The store clerk operates the registration screen button BT26, for example, when changing (adding or canceling) purchased products.

For example, the store clerk may be provided with a drawer or a change bill machine operated by the store clerk, and the store clerk may receive cash or the like from the customer and perform settlement processing. In this case, in FIG. 14, the cash total button BT20 also serves as a button for instructing the input of the deposit amount, and the cash total button BT20 is used when the clerk receives cash or the like from the customer and performs settlement processing. can be If a cash drawer is provided on the store clerk side, the change is calculated by inputting the deposit amount and pressing the cash total button BT20, and the receipt is issued. When a change bill machine is provided on the clerk side, when the clerk deposits the cash received from the customer into the change bill machine, the amount of money deposited is automatically calculated, and the change is paid by pressing the cash total button BT20. It becomes an operation to put out. As described above, the cash total button BT20 is a button that is operated after a deposit amount equal to or greater than the total amount has been input. do not have. Therefore, in FIG. 14, like the second register button BT22, the cash total button BT20 may also be displayed in a display mode indicating that the operation is not valid.

Thus, when the registration processing for one transaction is completed, the registration processing for the next transaction can be performed. The following one transaction is described below. FIG. 15 is a display example of a registration screen displayed on the clerk-side display unit 210 of the first POS terminal 20-1 at the time of the next transaction. Specifically, FIG. 15 shows the display contents of the registration screen when two products (carrots) are registered. The registration screen is displayed, for example, after a store clerk reads a bar code (product code, etc.) attached to a product and registration processing is started.

The registration screen has a structure in which a sheet (product registration sheet) indicating product registration details corresponding to each transaction is superimposed when a plurality of transactions are performed. For example, in FIG. 15, two product registration sheets are displayed. The product registration tabs (areas) TAB-1 and TAB-2 display the patterns of arbitrary animals (here, "cat" and "cow"). When multiple product registration tabs are displayed, the product registration tab corresponding to the current transaction to be registered is displayed large, and the other tabs are displayed small. In the example shown in FIG. 15, since the transaction of the product registration tab (area) TAB-2 is to be registered, the product registration tab (area) TAB-2 is displayed large, and the product registration tab (area) not to be registered is displayed. TAB-1 is displayed small.

In addition, the status of the corresponding transaction is shown in the product registration tab (area) TAB-1 that is not subject to registration. In FIG. 15, "No. 2 cash register" is displayed on the product registration tab (area) TAB-1, and the transaction corresponding to the product registration tab (area) TAB-1 is processed (settlement processing) at the No. 2 cash register. It indicates the purpose.

The product registration tabs (regions) are displayed one by one each time the transaction increases by one, and each time the transaction ends, the product registration tabs (regions) are erased. Note that registration order numbers such as "1", "2", and "3" may be displayed instead of arbitrary animal designs. The registration order number indicates, for example, the order in which product registration was started.

An image GA01 and an image GA02 are displayed at the lower left of the product registration sheet to which the product registration tab (area) TAB-2 of "cow" is attached, and a subtotal button BT10 and a pause button BT11 are displayed at the lower right of the product registration sheet. is displayed. These displays are common to any product registration sheet.

When multiple product registration tabs (regions) are displayed, a recall button BT27 is displayed to the left of the subtotal button BT10. The recall button BT27 is a button for recalling registration information transmitted to another POS terminal (the second POS terminal 20-2 or the third POS terminal 20-3). The store clerk operates (touches) the recall button BT27 when recalling the registration information transmitted to the other POS terminal 20 (for example, the second POS terminal 20-2).

When the subtotal key is operated, a subplan screen such as that shown in FIG. 14 is displayed. Further, when the recall button BT27 is operated, the transaction registration information corresponding to the product registration tab (area) TAB-1 transmitted to the second POS terminal 20-2 is recalled from the second POS terminal 20-2 and shown in FIG. As shown, the product registration sheet of the product registration tab (area) TAB-1 is displayed. At this time, the product registration tab (area) TAB-2 is displayed in a small size. Also, "Registered" is displayed in the product registration tab (area) TAB-2, indicating that the transaction corresponding to the product registration tab (area) TAB-2 is being registered.

A settlement screen is displayed on the second POS terminal 20-2 to which the registration information has been sent. The settlement screen is the same screen as the settlement screen (payment method selection screen) displayed when starting the settlement process in the full-self mode shown in FIG. 12(A). In the semi-self mode, images shown in FIG. 12 are sequentially displayed on the customer-side display section 205, and the customer follows the procedures displayed on the customer-side display section 205 to carry out payment processing. While the settlement process is being performed, the recall button BT27 shown in FIG. By operating (pressing), the registration information transmitted to the second POS terminal 20-2 is recalled to the first POS terminal 20-1.

When the product registration sheet of the product registration tab (area) TAB-1 shown in FIG. 16 is displayed, the product registration in the transaction of the product registration tab (area) TAB-1 can be restarted and additional products can be purchased. . Specifically, FIG. 17 shows the display contents of the registration screen when the third product (mint gum) is registered.

When the subtotal button BT10 shown in FIG. 17 is operated, a subplan screen shown in FIG. 18 is displayed. On the sub-plan screen shown in FIG. 18, a cash total button BT20 is displayed in the same manner as the sub-plan screen shown in FIG. After the registration information is recalled, the first POS terminal 20-1 shifts to the normal mode, so the first checkout button BT21, the second checkout button BT22, and the checkout button BT25 shown in FIG. 14 are displayed. not. The deposit amount is input by operating the cash total button BT20.

Furthermore, when a new transaction is started while the product registration tab (area) TAB-1 and the product registration tab (area) TAB-2 are displayed, a new product registration tab ( area) TAB-3 is displayed. A product registration tab (area) TAB-3 displays a "koala" design. Here, there is shown a state in which the transaction is being registered in the product registration tab (area) TAB-1.

Further, when recalling the registered information, if the POS terminal (the first POS terminal 20-1) is in a state where settlement processing cannot be performed, the recalled information cannot be recalled. The state in which settlement processing cannot be performed at the POS terminal includes, for example, near-end, near-full, out-of-receipt, failure of the change dispenser 209 or the printing unit 213, and the like. For the determination of near-end, near-full, out-of-receipt, etc., for example, a threshold may be set for each, and when the threshold is exceeded, it may be determined that the state is near-end, near-full, out-of-receipt, and the like. In this case, even if the recall button BT27 shown in FIG. 15 is operated, the transaction registration information in the product registration tab (area) TAB-1 is not displayed, and the reason why recall is not possible is displayed.

FIG. 20 shows error information when the settlement process cannot be performed, such as the display when the registration information cannot be recalled due to near-end. As specific error information, a message image GA20 containing the message "Insufficient change. Unable to call back" is displayed to notify the clerk that the call cannot be recalled. In this case, for example, the account can be settled by transmitting the registration information to the POS terminal (the second POS terminal 20-2) that called back the registration information or another POS terminal (for example, the third POS terminal 20-3). can.

Next, in the semi-self mode, processing in the first POS terminal 20-1 from registration processing to settlement processing will be described. FIG. 21 is a flow chart showing an example from the execution of the registration process to the execution of the settlement process in the first POS terminal.

Step S201: It is determined whether or not there is an operation for specifying a settlement device. Specifically, it is determined whether or not the first register button BT21 or the second register button BT22 shown in FIG. 14 has been operated (touched). If the first register button BT21 or the second register button BT22 is operated, the process proceeds to step S202. If there is no first register button BT21 or second register button BT22, the process of step S201 is repeated.
Step S202: Transmit registration information. Here, the registration information is transmitted to the register (POS terminal 20) corresponding to the operated register button. Specifically, when the first register button BT21 is operated, the registration information is transmitted to the No. 2 register (second POS terminal 20-2). Also, when the second register button BT22 is operated, the registration information is transmitted to the No. 3 register (third POS terminal 20-3).

Step S203: Display the product registration tab (area). Here, a product registration tab for performing the next registration and a product registration sheet corresponding to this product registration tab (area) are displayed. Only the product registration tab (area) is displayed for the transaction for which the registration information has been sent, and the product registration sheet is hidden in the product registration sheet for the next transaction.
Step S204: Judge whether or not the settlement process is completed. Specifically, it is determined whether or not payment completion information has been received from the POS terminal 20 (the second POS terminal 20-2 or the third POS terminal 20-3) that transmitted the registration information. When the settlement completion information is received, it is determined that the settlement processing is completed, and when the settlement completion information is not received, it is determined that the settlement processing is not completed. If it is determined that the settlement process has been completed, the process proceeds to step S205. If it is determined that the settlement process has not been completed, the process of step S204 is repeated.
Step S205: Delete the corresponding product registration tab (area). Specifically, the product registration tab (region) for the transaction sent to the other cashier (No. 2 cashier or No. 3 cashier) is deleted. Then, the flowchart of FIG. 21 ends.

Next, the process in the first POS terminal 20-1 in the case of recalling the registered information while the settlement process is being performed in the semi-self mode will be described. FIG. 22 is a flow chart showing an example of processing when recalling registration information during settlement processing at the first POS terminal.

Step S301: Determine whether or not the recall button has been operated. Specifically, it is determined whether or not there is an operation to press the recall button BT27 shown in FIG. If the recall button has not been operated, the process of step S301 is repeated, and if the recall button BT27 has been operated, the process proceeds to step S302.
Step S302: Determine whether there is a status error. Specifically, it is determined whether or not there is a status error such as near-end, near-full, inability to transfer money due to a failure of the change dispenser 209 or the like, or inability to issue a receipt due to a failure of the receipt unit 213 or the like. If there is a status error, the process proceeds to step S308. If there is no status error, the process proceeds to step S303.

Step S303: Determine whether there are multiple recall candidates. Specifically, it is determined whether or not there are a plurality of unsettled transactions other than the transaction currently being registered. Candidates for recall are transaction registration information of product registration tabs (areas) other than the product registration tab (area) of the transaction currently being registered among the product registration tabs (areas) shown in FIG. Therefore, if there are a plurality of product registration tabs (areas) other than the product registration tab (area) of the transaction currently being registered, there are a plurality of recall candidates. In the example shown in FIG. 15, there is only one product registration tab (area) other than the product registration tab (area) (product registration tab (area) TAB-2) of the transaction currently being registered ( Since the product registration tab (area) is TAB-1 only), there is only one recall candidate. Also, as shown in FIG. 19, there are a plurality (two) of product registration tabs (areas) other than the product registration tab (area) (product registration tab (area) TAB-1) of the transaction currently being registered. If there is (product registration tab (area) TAB-2, product registration tab (area) TAB-3), the product registration tab (area) other than the product registration tab (area) of the transaction currently being registered The store clerk selects and operates one of the product registration tabs (regions) TAB-2 and product registration tabs (regions) TAB-3.

Step S304: Determine whether or not the product registration tab (area) has been operated. If there are multiple registration information for transactions that are candidates for recall, multiple product registration tabs (areas) for the corresponding transactions will be displayed. A salesclerk operates a tab (area). When the product registration tab (area) is operated, the process proceeds to step S305. If the product registration tab (region) has not been operated, the process of step S304 is repeated.
Step S305: Send the recall information to the POS terminal that is performing transaction settlement processing. When there is only one product registration tab (area) other than the product registration tab (area) of the transaction currently being registered, the call is returned to the POS terminal 20 that performs settlement processing for the transaction of the product registration tab (area). Send information. For example, when the call back button BT27 is sent on the screen shown in FIG. 15, the call back information is sent to the No. 2 cash register (second POS terminal 20-2). When there are a plurality of product registration tabs (areas) other than the product registration tab (area) of the transaction currently being registered, the POS that performs settlement processing for the transaction of the product registration tab (area) operated in step S304. Send callback information to the terminal 20 . For example, when the product registration tab (area) TAB-2 is operated on the screen shown in FIG. 19, the recall information is transmitted to the No. 2 register (second POS terminal 20-2).

Step S306: Determine whether or not the returned registration information has been received. The POS terminal 20 that has received the recall information returns registration information to the POS terminal 20 that transmitted the recall information. Here, it is determined whether or not the returned registration information has been received. If the returned registration information has been received, the process proceeds to step S307. If the returned registration information has not been received, the process of step S006 is repeated.
Step S307: Display the corresponding product registration tab (area) and product registration sheet. When the registration information returned from the POS terminal 20 that sent the recall information is received, the product registration tab (area) corresponding to the registration information is changed to the product registration tab (area) TAB-1 shown in FIG. , and display the product registration sheet. The product registration tab (area) that was displayed large at this time is displayed in a small size like the product registration tab (area) TAB-2 shown in FIG. Place it on the back side. Also, the operation mode of the first POS terminal 20-1, which was in the full self mode, shifts to the normal mode. Then, the flowchart of FIG. 22 ends.

Step S308: Display the error content. The content of the status error is displayed when it is determined that there is a status error in step S302. For example, when the POS terminal 20 is near-end, the message image GA20 shown in FIG. Then, the flowchart of FIG. 22 ends.

(Display on customer-side display unit 205 of second POS terminal 20-2)
Next, FIGS. 23 to 25, etc., will be used for the display of the customer-side display unit 205 in the POS terminal 20 (second POS terminal 20-2) when performing product registration, transmission of registration information, and recall of the transmitted registration information. to explain. 23 to 25 are display examples of the customer-side display section of the second POS terminal 20-2.

FIG. 23 is a display example of the checkout screen displayed on the customer-side display section 205 of the second POS terminal 20-2. Specifically, FIG. 23 shows a state in which the settlement process has progressed and recall information has been transmitted from the first POS terminal 20-1 in the scene shown in FIG. 12(C). When the recall information is transmitted from the first POS terminal 20-1, the second POS terminal 20-2 transmits the registration information to the first POS terminal 20-1, and the customer side display section 205 of the second POS terminal 20-2. As shown in FIG. 23, a message image GA31 including the message "You have been called back to the No. 1 cash register" is displayed to inform the customer that the registration information has been called back to the No. 1 cash register (first POS terminal 20-1). to be notified.

In the scene shown in FIG. 12(C), the customer has already put in cash for payment. When the registered information is recalled, the customer is made to select the handling of the cash thrown in by the customer. Therefore, following the image shown in FIG. 23, a deposit refund inquiry screen is displayed as shown in FIG. The deposit refund inquiry screen displays a message image GA32 including the message "Would you like to refund the deposit?" is displayed.

The coin withdrawal button BT51 displays a message "withdraw only coins". When the coin withdrawal button BT51 is operated, only the coins of the deposited money are withdrawn, and the amount of the deposited banknotes is the same. is transmitted to the first POS terminal 20-1 together with the registration information. The bill withdrawal button BT52 displays a message "withdraw only bills", and when the bill withdrawal button BT52 is operated, only the bills of the deposited money are withdrawn, and the amount of the deposited coins is displayed. is transmitted to the first POS terminal 20-1 together with the registration information.

The full refund button BT53 displays the message "Full refund", and when the full refund button BT53 is operated, the full amount deposited is refunded. A message "Full amount as is" is displayed on the full amount maintenance button BT54, and when the full amount maintenance button BT54 is operated, the information of the total amount deposited is sent to the first POS terminal 20-1 together with the registration information. As shown in FIG. 12(A) or FIG. 12(B), when the second POS terminal 20-2 receives recall information before payment is made, the image shown in FIG. 24 is not displayed. The image shown at 25 is displayed.

FIG. 25 is an image displayed after the image shown in FIG. 23 or the image shown in FIG. 24 is displayed. As shown in FIG. 25, a message image GA41 including the message "Please return to No. 1 cashier" is displayed on the customer-side display section 205 of the second POS terminal 20-2. An OK button BT61 displaying "OK" is displayed in the message image GA41. When the customer is performing the settlement process at the second POS terminal 20-2, the customer sees this message image GA41 and operates the OK button BT61 to return to the first POS terminal 20-1. In addition to the OK button BT, a clerk call button may be provided to call the clerk. By calling the store clerk, the customer can check the content of the change and subsequent processing without leaving the second POS terminal 20-2.

After the registration information is recalled to the first POS terminal 20-1 in this way, the second POS terminal 20-2 shifts to the full self mode. Therefore, the registration start screen (see FIG. 11A) in the full-self mode is displayed on the customer-side display section 205 of the second POS terminal 20-2. After the message included in the message image GA41 is displayed for a predetermined time, for example, several seconds without providing the OK button BT61 shown in FIG. You may do so. Also, if the registration information for the next transaction has been sent to the second POS terminal 20-2, the settlement screen will continue to be displayed in order to start settlement processing for the next transaction without shifting to the full self mode. be done.

In the first POS terminal 20-1, when the current customer is being registered, the customer may be called back after the process is completed, or the registration of the current customer may be "temporarily suspended" and the registered data of the previous customer may be retrieved. may be corrected, but in the case of temporary suspension, the product registration tab (region) where the previous customer's product registration was performed is left until the settlement process of the previous customer is completed. At this time, the store clerk may perform recall operation by touching the product registration tab (region) of the previous customer. Also, at that time, you can display a confirmation screen such as "I will call you back. Are you sure (Yes / No)" or only a screen (OK)? It is also possible to call back without displaying the confirmation screen, thereby facilitating the recall operation and avoiding operational errors.

Next, the processing in the second POS terminal 20-2 when the recall information of the registration information is transmitted from the first POS terminal 20-1 during settlement processing in the semi-self mode will be described. FIG. 26 is a flow chart showing an example of the operation of the second POS terminal that has received the callback information.

Step S401: Determine whether or not registration information has been received. Here, it is determined whether or not registration information has been received from the first POS terminal 20-1. If the registration information has not been received, the process of step S401 is repeated, and if the registration information has been received, the process proceeds to step S402.
Step S402: Display the settlement screen. Here, the settlement screen (payment method selection screen) shown in FIG. 12A is displayed on the customer side display section 205 of the second POS terminal 20-2.

Step S403: It is determined whether or not the end (receipt) button has been operated. After the screen shown in FIG. 12(A) is displayed on the customer-side display unit 205 of the second POS terminal 20-2, the settlement process proceeds, and the end (receipt) button BT40 shown in FIG. 12(C) is operated. determine whether or not If the end (receipt) button BT40 has not been operated, the process proceeds to step S404, and if the end (receipt) button BT40 has been operated, the process proceeds to step S412.
Step S404: Determine whether the call-back information is received. Here, it is determined whether or not the recall information transmitted from the first POS terminal 20-1 has been received. If the call-back information has been received, the process proceeds to step S405. If no callback information has been received, the flowchart of FIG. 26 ends.

Step S405: Return registration information. Here, the second POS terminal 20-2 returns the registration information received in step S401 to the first POS terminal 20-1.
Step S406: Display the settlement screen (recall notification screen). Here, an image including the message image GA31 shown in FIG. It is displayed on the customer side display unit 205 .

Step S407: Display the settlement screen (deposit refund inquiry screen). Here, a deposit refund inquiry screen including a message image GA32 shown in FIG. 25 is displayed.
Step S408: Execute processing according to the operated button. Specifically, when any one of the coin refund button BT51, banknote refund button BT52, full refund button BT53, and full refund button BT54 included in the message image GA32 shown in FIG. 25 is operated, a process corresponding to the operation is executed. do. When the coin withdrawal button BT51 is operated, the coins of the deposited money are withdrawn, and the bill amount information is sent to the first POS terminal 20-1 together with the registration information. When the banknote withdrawal button BT52 is operated, the banknotes of the deposited money are withdrawn, and information on the coin amount is sent to the first POS terminal 20-1 together with the registration information. When the full refund button BT53 is operated, the full amount of the deposited money is refunded. When the full amount maintenance button BT54 is operated, information on the total amount deposited is sent to the first POS terminal 20-1 together with the registration information.

Step S409: Display a movement instruction. After any one of the coin refund button BT51, bill refund button BT52, full refund button BT53, and full refund button BT54 is operated, a message image GA41 shown in FIG. 25 is displayed. An OK button BT61 is displayed in the message image GA41.
Step S410: Determine whether the OK button has been operated. If the OK button BT61 shown in FIG. 25 has been operated, the process proceeds to step S411. If the OK button BT61 has not been operated, the process of step S410 is repeated.

Step S411: Display the registration start screen (full self mode). Here, the second POS terminal 20-2 is shifted to the full self mode, and the start screen of the full self mode is displayed on the customer-side display section 205 of the second POS terminal 20-2. Then, the flowchart of FIG. 26 ends.
Step S412: Transmit payment completion information. In step S403, when the end (receipt) button BT40 is operated, the settlement process is completed. Therefore, the second POS terminal 20-2 receives the settlement completion information from the first POS terminal 20-1. Then, the flow chart of FIG. 26 ends.

As described above, according to the present embodiment, when the POS terminal 20 is operated in the semi-self mode, the POS terminal 20 (for example, the first POS terminal 20-1) that performs the registration process transmits the registration information. The registered information can be recalled from the POS terminal 20 (for example, the second POS terminal 20-2) that performs the settlement process. After recalling the registration information, the first POS terminal 20-1 shifts the operation mode from the semi-self mode to the normal mode. At this time, when the first POS terminal 20-1 is in a state in which settlement is not possible, for example, when a status error occurs, recall cannot be performed. Allows you to call back. Therefore, even if the registration information is recalled, the registration information will not be recalled if the settlement cannot be made. 20 can be operated efficiently.

Further, since the checkable state of the first POS terminal 20-1 is determined based on the status such as whether or not there is a status error, it is possible to accurately determine the checkable state of the first POS terminal 20-1. As a result, multiple POS terminals 20 can be efficiently operated.

Further, according to the present embodiment, when the second POS terminal 20-2 recalls the registration information transmitted from the first POS terminal 20-1, the operation mode is set to the full self mode, which is a mode other than the semi self mode. The screen displayed after the transition is made and the registration information is recalled is the full self mode registration start screen. Therefore, the second POS terminal 20-2, which has been operating in the semi-self mode, can be used in the full self mode by recalling the registration information. Therefore, the operation mode can be switched according to the recall operation. In addition, the operation mode can be switched without the store clerk manually performing the mode switching process. Also, when a customer who wants to use the second POS terminal 20-2 in full self mode is waiting, the second POS terminal 20-2 can quickly start the registration process. Therefore, the second POS terminal 20-2 can be used efficiently after the registration information is recalled.

The operation mode in which the second POS terminal 20-2 shifts from the semi-self mode is the full self mode. Therefore, even if there is no store clerk near the second POS terminal 20-2, the second POS terminal 20-2 whose registration information has been transferred can be quickly put into operation by the customer alone. Therefore, since the second POS terminal 20-2 can be operated simultaneously while the first POS terminal 20-1 is operating, a plurality of POS terminals can be efficiently operated.

Also, the second POS terminal 20-2 returns registration information to the first POS terminal 20-1 in response to the recall information transmitted from the first POS terminal 20-1. Therefore, since information can be exchanged between the first POS terminal 20-1 and the second POS terminal 20-2, the registration information can be corrected smoothly.

The POS terminal 20 also has a change dispenser 209 for inserting cash. When the second POS terminal 20-2 receives the recall information from the first POS terminal 20-1, the deposited cash is refunded. For this reason, when performing settlement after the registration information is recalled, miscalculation of money can be suppressed even if there is an additional purchase or cancellation of merchandise.

When the second POS terminal 20-2 receives the recall information from the first POS terminal 20-1, the second POS terminal 20-2 withdraws banknotes out of the deposited cash and transmits information on the amount of coins to the first POS terminal 20-1. is doing. For this reason, it is possible to reduce the risk of losing banknotes in the event that additional merchandise is purchased or canceled when the account is settled after the registration information is recalled.

Further, when the second POS terminal 20-2 receives the recall information from the first POS terminal 20-1, the second POS terminal 20-2 withdraws coins out of the deposited cash and transmits information on the amount of bills to the first POS terminal 20-1. is doing. This saves the trouble of re-depositing the same banknote that has been deposited once, thereby simplifying the depositing operation, especially the depositing operation of banknotes.

Further, when the second POS terminal 20-2 receives the recall information from the first POS terminal 20-1, it transmits the information of the deposited cash together with the registration information to the first POS terminal 20-1. This saves the trouble of re-depositing the money once deposited, thus simplifying the depositing operation. In addition, since there is no cash refund, it is possible to prevent forgetting to receive the paid cash.

In the above example, the POS system 1 includes the first POS terminal 20-1, the second POS terminal 20-2, and the third POS terminal 20-3, but the POS system 1 includes two POS terminals. POS terminals may be provided, or four or more POS terminals may be provided. Also, the POS system 1 includes a store controller 10 other than the POS terminals 20, but may be configured without a store controller. In this case, a specific one or any one of the POS terminals 20 may It may have functions similar to those of the controller.

In the above example, when recalling registered information, after operating the recall button BT27, if there are multiple recall candidates, the product registration tab is operated to select the registered information to be recalled. However, the registration information to be recalled may be selected in another manner. For example, by operating the recall button BT27, an unsettled process list screen including a list of registered information of unsettled transactions in other POS terminals 20 is displayed, and the recalled information is recalled from the displayed list of registered information. You may make it select the registration information which carries out. This list may include registration information for transactions that are being registered in addition to registration information for unsettled transactions. Also, the registered information that has been settled may be displayed in a different manner from that of the unsettled registration information, for example, the background color and pattern, the character color and size, and the font may be changed. When selecting the registered information to be recalled from the unsettled processing list screen, the transaction information can be displayed side by side by selecting the list, so that the recall operation can be performed after confirming the transaction details. In addition, when there is a store clerk at the third POS terminal 20-3 other than the first POS terminal 20-1, the recall can be performed regardless of the registered device.

Further, in the above example, the registration information is transferred by the first POS terminal 20-1 that has performed the registration process recalling the registration information from the second POS terminal 20-2, but other modes may be adopted. For example, when the registration information is transmitted from the first POS terminal 20-1 that performed the registration process to the second POS terminal 20-2 and the second POS terminal 20-2 attempts to perform the settlement process, the second POS terminal 20-2 Transfer information for moving the transmitted registration information to another POS terminal 20, for example, the third POS terminal 20-3 is transmitted to the second POS terminal 20-2, and the registration information is transferred from the second POS terminal 20-2 to the third POS terminal 20. You may make it move to -3.

In the above example, the first POS terminal 20-1 that has transmitted the registration information to the second POS terminal 20-2 does not store the transmitted registration information, but prepares the transmitted registration information or a copy thereof in advance. After sending the registration information, the registration information or a copy thereof may be stored. Also, part of the registration information or a copy thereof may be stored. A part of the registration information returned from the second POS terminal 20-2, for example, only the transaction number may be returned. In addition, the transmission and reception of information is not limited to direct transmission and reception between the transmission destination and the reception destination. Send and receive.

Also, in the above example, whether or not to call back is determined based on the status information, but whether or not to call back may be determined based on other conditions. For example, when the first POS terminal 20-1 has a settlement machine for settlement by credit card or electronic money, it may be possible to recall the credit card displayed on the button shown in FIG. 12(A). After deciding to pay with or electronic money, the first POS terminal 20-1 may be configured to be able to recall when the credit card or electronic money used for these payment methods can be used. Alternatively, it may be made unconditionally recallable.

In the above example, only one piece of transaction information can be stored in the POS terminal 20, but two or more items of transaction information may be stored so that settlement processing can be performed sequentially. . In this case, one POS terminal 20 may store a plurality of pieces of registration information, or a plurality of POS terminals may store registration information.

In this case, when selecting the POS terminal 20 for recalling the registration information, the color, shape, animal pattern, etc. of the product registration tab (area) TAB may be displayed with characteristics for each POS terminal. For example, the product registration of the first POS terminal 20-1, in which the registration information about the transaction first transmitted to the second POS terminal 20-2 is described, may have a different color for each POS terminal 20. FIG. For example, the product registration tab (area) of the transaction registration information sent to the second POS terminal 20-2 has a red background, and the product registration tab (area) of the transaction registration information sent to the third POS terminal 20-3 is colored red. ) may have an all-blue background.

Also, the color or the like may be changed for each cycle registered in each POS terminal 20 . For example, in each of the second POS terminal 20-2 and the third POS terminal 20-3, the first transmitted transaction registration information is displayed in yellow, and the second transmitted transaction registration information is displayed in green product registration tabs (regions). It may be filled out in a product registration sheet marked with Further, instead of the same color or the like, similar or approximate colors or the like may be used. For example, the registration information stored in the second POS terminal 20-2 is red, orange, vermilion, pink, etc., and the registration information stored in the third POS terminal 20-3 is blue, green, etc. , light blue, bluish purple, and the like.

Further, when the second POS terminal 20-2 can store a plurality of pieces of registration information, when the registration information of the transaction currently being settled is recalled with the plurality of pieces of registration information stored, the full self mode is activated. The semi-self mode may be maintained without transitioning to . In other words, when the second POS terminal 20-2 detects the return of the registration information, it determines whether or not the registration information is stored. is maintained in the semi-self mode. In this case, the POS terminal can be operated efficiently because the settlement process for the already stored registration information can be performed smoothly. Further, when the registered information is recalled, the second POS terminal 20-2 may be on standby waiting for the recalled registered information to be corrected. In this case, the customer does not move from the second POS terminal 20-2 and waits for the registration information to be sent again. A selection screen may be displayed on the customer-side display unit 205 so that the customer can select whether to wait or shift to the full self mode. Further, when registration processing or settlement processing is performed in full-self mode, after completion of settlement processing, if registration information is not stored, the mode may be shifted to semi-self mode. In this case, even if the registration information is not stored, for example, if the next customer wants to start the registration process in the full self mode after the settlement process in the full self mode is completed, the semi self mode You may make it prohibit the shift to. In order to prohibit the transition to the semi-self mode in this case, for example, the transition to the semi-self mode may be made after a predetermined period of time, for example 10 seconds, has elapsed after the processing in the full self mode is completed. The transition to the semi-self mode may be prohibited when the next customer is detected by the human sensor.

Further, the POS terminal 20 may store transaction registration information transmitted from another POS terminal 20 to another POS terminal 20 as unsettled registration information. For example, when the first POS terminal 20-1 transmits registration information to the second POS terminal 20-2, the third POS terminal 20-3 may receive and store the registration information from the second POS terminal 20-2. . In this case, for example, the third POS terminal 20-3 may transmit the collection information to the second POS terminal 20-2. In this way, the registration information is transferred between the POS terminals 20 in a manner such as call-back and pick-up. In addition, unsettled registered information transferred between a plurality of POS terminals 20 can be displayed as unsettled information in product registration tabs (regions) or displayed as a list of unsettled products on all POS terminals 20. You may make it so.

Further, in the above example, the second POS terminal 20-2, which has sent back the registration information in the semi-self mode, shifts to the full self mode, and the customer-side display unit 205 of the second POS terminal 20-2 displays the full self mode. The mode registration start screen is displayed, but you may shift to another mode. For example, it may shift to normal mode or double scan mode. In this case, the customer-side display unit 205 of the second POS terminal 20-2 may display the first screen in the normal mode or the double scan mode. Also, the second POS terminal 20-2 that has returned the registration information may remain in the self mode. In this case, the customer-side display unit 205 of the second POS terminal 20-2 that sent back the registration information only needs to display the first screen displayed in the semi-self mode.

Further, in the above example, when the first POS terminal 20-1 is in the settlement disabled state, the registered information cannot be recalled, and when the settlement is possible, the registered information can be recalled. It may be possible to recall the registration information even when the customer is in an unsettled state. In this case, the first POS terminal 20-1 transmits new registration information of the transaction containing the recalled registration information to the other POS terminals (second POS terminal 20-2, third POS terminal 20-3, etc.). It is preferable to have the operator perform the settlement process. In this case, the POS terminal 20 that transmits the new registration information may be the POS terminal 20 whose registration information has been recalled, or the POS terminal 20 that transmits the registration information may be designated (selected) again. The selection in this case may include the own device. When sending new registration information to the POS terminal 20 whose registration information has been recalled, the customer must remain near the POS terminal 20 (for example, the second POS terminal 20-2) until the new registration information is sent. Alternatively, after moving to the POS terminal 20 (for example, the first POS terminal 20-1) that performs the registration process, it moves to the POS terminal (for example, the second POS terminal 20-2) that performs the payment again. You may make it In the case of a mode in which the POS terminal 20 to which the registration information is to be transmitted is specified again, the customer, for example, calls back the POS terminal 20 (eg, the first POS terminal 20-2) from the recalled POS terminal (eg, the second POS terminal 20-2). 1) to add or delete registration information, and then to a designated POS terminal (for example, the third POS terminal 20-3) to perform settlement processing.

Further, in the above example, when the registration information is recalled during the payment-only mode, the POS terminal (second POS terminal 20-1) that shifts to the full-self mode is in the normal mode, the full-self mode, the semi-self mode, and double scan mode, but if the semi-self mode and the full self mode are provided, the other modes may not be provided. The POS terminal 20 has operation modes such as a normal mode, a full-self mode, and a semi-self mode, but the POS terminal may be a POS terminal that performs at least one of registration processing and settlement processing without having an operation mode. In this case, although there is no definite concept of an operation mode, at least some of the functions equivalent to the functions of the POS terminal 20 in the above example are provided according to the provided information and processing by the clerk. good too.

Further, in the above example, the call-back is performed in any of the following status errors: near-end, near-full, inability to transfer money due to a failure of the change dispenser 209, etc., or inability to issue a receipt due to a failure in the printing unit 213 or out of receipts. However, recall may be disabled if either of these occur. Also, it may be possible to determine whether or not recall is possible according to the state of each status. For example, even at near-end, recall may or may not be possible depending on the type of currency.

Further, in the above example, recalling of registered information can be performed even when settlement processing is being performed at the first POS terminal 20-1. may be made so that it cannot be recalled. In this case, it is possible to reduce the concern that the settlement process will be complicated. As a result, multiple POS terminals 20 can be efficiently operated.

Further, in the above example, when the registration information is recalled while payment is being processed at the second POS terminal 20-2, the refund of the deposited money can be set in full, only banknotes, or only money. etc., but these may be determined in one of the modes and may not be selected. Also, if there are options that cannot be selected, for example, if there is an option to withdraw only banknotes even though no banknotes have been deposited, the buttons for the options that cannot be selected are not displayed or displayed grayed out. to prevent the customer from selecting.

Further, in the above example, the registration information is transferred between the plurality of POS terminals 20 by sending/receiving or replying, but the registration information may be transferred in another mode. For example, registration information may be written in a code attached to a medium, such as a shopping ticket, and the registration information may be transferred by moving the medium.

Also, in the above example, the recall information is transmitted by the POS terminal that performs the recall, but the recall information may be transmitted by another POS terminal 20 or the store controller 10 . For example, for the registration information transmitted from the first POS terminal 20-1 to the second POS terminal 20-2, the store controller 10 calls to return the registration information from the second POS terminal 20-2 to the first POS terminal 20-1. Return information may be sent to the second POS terminal 20-2. Also, when the registration information transmitted from the first POS terminal 20-1 to the second POS terminal 20-2 is moved to the third POS terminal 20-3, the collection information is sent from the POS terminal 20 or the like other than the third POS terminal 20-3. may be transmitted from another POS terminal 20 or the store controller 10 instead of transmitting the .

In the above example, the POS system 1 includes the POS terminal 20 capable of performing both registration processing and settlement processing, but may include other POS terminals. . For example, a POS terminal that can perform registration processing but cannot perform settlement processing may be included, or a POS terminal that cannot perform registration processing but can perform settlement processing may be included. These POS terminals may be provided in place of the POS terminal 20 capable of performing both registration processing and settlement processing.

In the above example, when the POS terminal 20 transmits the registration information to the other POS terminals 20, the other POS terminals 20 are not particularly restricted, but some POS terminals 20 cannot transmit. may The POS terminal 20 that is disabled for transmission may, for example, be disabled for status errors such as near-end, near-full, and out-of-receipt situations. Further, transmission may be disabled when the number of registration information that can be registered in the POS terminal 20 reaches the upper limit. Further, whether or not transmission is possible may differ depending on the operation mode of the POS terminal 20 . For example, transmission to the POS terminal 20 in normal mode may be disabled. When judging the mode, whether it is valid or invalid may be determined by flag management, etc., depending on system conditions, etc.). Further, in the case of the POS terminal 20 in full self mode or payment mode, transmission may be disabled when other customers are operating. Further, the conditions of the POS terminal 20 for disabling transmission of registration information and the conditions for the POS terminal 20 for disabling recall may be the same or different.

Also, in the above example, a receipt or a receipt (receipt, etc.) is issued when the settlement is completed, but for example, a receipt (receipt) unnecessary button is provided to omit the issuance of (receipt, etc.) You may make it possible. The no-receipt button may be provided, for example, on the customer-side display section 205 or on the clerk-side display section 210 . Alternatively, it may be provided in the key operation unit 211 . By making it possible to omit the issuing of receipts (such as receipts), it is possible to contribute to the reduction of receipt paper.

In addition, when omitting the issuance of receipts printed on paper media such as receipt paper, electronic receipts may be issued instead of receipts. In this case, for example, by performing user registration in advance and entering user identification information (membership number), etc., an electronic receipt may be automatically issued instead of a receipt, etc. or an electronic receipt. Alternatively, both receipts and electronic receipts may be issued. In this case, a selection screen may be displayed to allow the customer to make a selection, or the display of the selection screen may be omitted by, for example, registering a selection pattern for each user in advance. As the mode of issuing receipts, for example, it may be possible to select from among non-issuing, only paper media, only electronic receipts, and both paper media and electronic receipts. The selection screen in this case may be provided on at least one of the customer-side display section 205 , the salesclerk-side display section 210 and the key operation section 211 . At this time, a receipt or the like may be issued at the same time as the change is issued. When the change is paid out and the receipt or the like is issued, the receipt or the like may be issued after the change is paid out, or the change may be paid out after the receipt or the like is issued. Also, when a receipt is issued, change may be paid out after the customer receives the receipt to prevent the customer from forgetting to take the receipt.

If the second POS terminal 20-2 and the third POS terminal 20-3 are on standby while the clerk is operating the first POS terminal 20-1, the second POS terminal 20-2 and the third POS terminal 20-3 Although the operation mode of is not particularly limited, for example, it may be a full self mode. By standing by in the full self mode, multiple POS terminals 20 can be used efficiently. Further, when the waiting time for checkout at the first POS terminal 20-1 increases, the clerk at the first POS terminal 20-1 transmits the registration information to either the second POS terminal 20-2 or the third POS terminal 20-3 to enter the settlement mode. can be operated as Alternatively, the registration information of the transaction for which registration processing has been completed is transmitted to the second POS terminal 20-2 or the third POS terminal 20-3, and the second POS terminal 20-2 or the third POS terminal 20-3 takes over the settlement processing. may For example, in a case where the second POS terminal 20-2 takes over the settlement process, and the second POS terminal 20-2 is operating in the full self mode, the registration information is transmitted to the second POS terminal 20-2, and the full After the settlement in the self mode is completed, the settlement screen (payment method selection screen) shown in FIG. 12(A) may be displayed instead of the registration start screen shown in FIG. 11(A).

In the above example, by operating the recall button BT27 with the product registration tab (area) open, the transaction registration information corresponding to the product registration tab (area) is recalled. Registration information may be recalled. For example, the registration information corresponding to the product registration tab (area) may be recalled by opening the product registration tab (area) after operating the recall button BT27, or after operating the recall button BT27. By operating the first checkout button BT21 or the second checkout button BT22, the registration information sent to the second POS terminal 20-2 or the third POS terminal 20-3 corresponding to the first checkout button BT21 or the second checkout button BT22. may be recalled.
