(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 performs product registration processing is referred to as a registration mode, and the mode in which payment processing is performed is referred to as a checkout mode, as a different approach from the above-described four operation mode classifications. There is

(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. As shown in FIG. 8A, at least one POS terminal 20 (POS terminal 20-1 in the example of FIG. 8) is , and the customer side of another POS terminal 20 (one of the POS terminals 20-2 and 20-3 in the example of FIG. 8) executes the settlement process. mode. That is, in the case of the semi-self mode, one or more terminals (in the example of FIG. 8, one of the POS terminals 20-1 as shown in FIG. 8B) enters the registration-only mode, and one or more other terminals (the In an example, as shown in FIG. 8C, two POS terminals 20-2 and 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 process is completed at the POS terminal 20 in registration-only mode (POS terminal 20-1 in the example of FIG. Then, it moves to the POS terminal 20-2), and the POS terminal 20 at the destination is supplied with information necessary for settlement processing (registration information generated at the POS terminal 20 in the registration-only mode, etc.).

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.

That is, in the semi-self mode, the product is first registered by the clerk of the POS terminal 20 (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 ( (one of the POS terminals 20-3 of the POS terminal 20-2) is specified (step S31: YES), the registration information is transmitted to the specified POS terminal 20 (step S32), and the POS in the registration-only mode Processing in the 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)).

(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. 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 semi-self mode, one or more POS terminals 20 in the registration-only mode and one or more POS terminals 20 in the accounting-only mode are required. , POS terminals 20-2 and 20-3 are operating in a semi-self mode (registration-only mode) and the other is operating in a 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 2. FIG.

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.

(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 product registration is completed, 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 exemplified. , or additionally can be displayed. 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. 11(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).

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. .

(Display with clerk's operation in full self mode)
Next, the display of the POS terminal 20 in the case where the operations from registration to payment are normally performed by the customer in the full-self mode, but the operation by the store clerk is required will be described. For example, the customer may need the help of a store clerk because the customer fails to register, does not understand the operation method, or has an error. In this case, when a specific condition is satisfied, the POS terminal 20 causes the display on the clerk-side display unit 210 to transition to a clerk operation screen operated by the clerk. In this case, the display contents displayed on the customer-side display section 205 and the salesclerk-side display section 210 are different. Here, the specific condition is, for example, a specific operation (for example, a or a specific number of touch operations). The specific condition is that the customer-side scanner unit 206 or the store-clerk-side scanner unit 212 reads the store clerk code. The specific condition is not limited to the above, and may be input of a preset password, for example.

FIG. 13 is a display example of a salesclerk operation screen displayed on the salesclerk side display section 210 of the POS terminal 20 in the full self mode. Various buttons for clerk operation are displayed on the illustrated clerk operation screen. A "discount" button is a button used when registering a discount amount. A "discount" button is a button used when registering a discount amount. The "cancel" button is used to collectively cancel transaction details (registered details) before completing the transaction. The "correction of designation" button is a button used when correcting the registered content. The "immediate correction" button is a button used when correcting the registration content immediately before. A "clear" button is a button used for correcting an erroneous numerical value or canceling an error display. The "00-9" button is a button used for inputting numbers. The "amount" button is a button used when inputting the amount of money for small classification registration. The "PLU" button is a button used for repeat registration after PLU (Price Look Up) registration by reading. The "small category" button is a button used when entering a small category in the small category amount registration. The "custody/cash total" button is a button used when completing product registration. A "reissue" button is a button used when reissuing a receipt. The "registration of products without barcode" button is used when presetting products without barcodes. The "start screen" button is a button used to transition to the registration start screen. A "receipt" button is a button used when issuing a receipt. The “set hibernation” button is a button used when putting the POS terminal 20 into hibernation. A "return" button is a button used when returning to the display of the previous screen (the screen before transitioning to the current screen).

When transitioning from the registration screen (FIG. 11B) to the clerk operation screen, the clerk operation screen shown in FIG. 13 is displayed. , the clerk operation screen is different from the clerk operation screen shown in Fig. 13. Fig. 14 shows the clerk operation screen displayed on the clerk side display unit 210 of the POS terminal 20 in the full self mode, which is the registration start screen. This is a display example of the clerk operation screen when transitioning from .In the illustrated example, the "clear" button, "00 to 9" button, "reissue" button, "start screen" button, "receipt" button, and In this manner, on the clerk operation screen, for example, the state at that time (for example, before starting registration, during registration, during payment, etc.) is preset as necessary. A button is displayed, and the same clerk operation screen may be displayed in any state.

(Operation of screen control processing when store clerk operates)
Next, the operation of the screen control processing by the POS terminal 20 when the clerk operates in the full self mode will be described. FIG. 15 is a flowchart showing an example of screen control processing according to this embodiment. Here, a case where a store clerk operates during the registration mode and during the settlement mode will be described.

Step S200: When the registration start button BT30 is operated on the registration start screen (see FIG. 11A), the POS terminal 20 proceeds to the process of step S202.
Step S202: The POS terminal 20 shifts to the registration mode, and displays a registration screen (see FIG. 11A) on the customer-side display section 205 and the salesclerk-side display section 210. FIG.

Step S204: In the registration mode, the POS terminal 20 determines whether or not the clerk-side scanner section 212 has read the clerk code. If it is determined that the salesclerk code has been read (step S204: YES), the process proceeds to step S208. On the other hand, if it is determined that the clerk code has not been read (step S204: NO), the process proceeds to step S206.

Step S206: If the clerk code has not been read, the POS terminal 20 determines whether or not the checkout button BT32 has been operated on the registration screen (that is, whether or not product registration has ended). If the checkout button BT32 is not operated and product registration is not completed (step S206: NO), the POS terminal 20 continues the processing of steps S202 to S204. On the other hand, if the checkout button BT32 is operated and product registration is completed (step S206: YES), the POS terminal 20 terminates the registration mode, proceeds to step S214, and shifts to the checkout mode.

Step S208: When it is determined in step S204 that the salesclerk code has been read, the POS terminal 20 causes the display of the salesclerk side display section 210 to transition from the registration screen to the salesclerk operation screen (see FIG. 13). Here, the display on the customer-side display unit 205 remains the registration screen. For example, on the store clerk operation screen, the store clerk can collectively cancel all of the customer's registration details so far, or correct a part of the registration details. Then, the process proceeds to step S210.

Step S210: The POS terminal 20 determines whether or not the "cancel" button (see FIG. 13) has been operated on the clerk operation screen (that is, whether or not registration has been canceled). If it is determined that the "cancel" button has been operated (step S210: YES), the transaction details (registered details) up to that point are collectively canceled, and the registration mode ends. Then, the POS terminal 20 causes both the customer-side display section 205 and the salesclerk-side display section 210 to transition to the registration start screen (see FIG. 11A), and returns to the process of step S200. On the other hand, if it is determined that the "cancel" button has not been operated (step S210: NO), the process proceeds to step S212.

Step S212: The POS terminal 20 determines whether or not the "custody/cash total" button has been operated on the clerk operation screen (that is, whether or not product registration has ended). Here, if there is a correction to the transaction details (registered details) that have been made before the end of product registration, the clerk can make the correction by operating the clerk operation screen. For example, by operating the "Specified Correction" button or the "Immediately Correction" button (see FIG. 13), a correction screen is displayed, and the contents of transactions (registered contents) up to that point can be corrected. If the "custody/cash total" button has not been operated (step S212: NO), the POS terminal 20 continues the processing of steps S208 to S210. On the other hand, if it is determined that the "custody/cash total" button has been operated on the clerk operation screen (step S212: YES), the POS terminal 20 terminates the registration mode, proceeds to the process of step S214, and enters the settlement mode. Transition.

Even when the store clerk operates during the settlement mode, basically, only the display of the store clerk side display unit 210 becomes the store clerk operation screen as in the registration mode.
Step S214: When shifting to the settlement mode, the POS terminal 20 displays a settlement screen (for example, a payment method selection screen (see FIG. 12A)) on the customer side display section 205 and the store clerk side display section 210. FIG. In addition, the POS terminal 20 changes the settlement screen to a payment method selection screen, a deposit screen (see FIG. 12(B)), a deposit determination screen (see FIG. 12(C)), and a change screen based on the customer's operation on the settlement screen. (See FIG. 12(D)).

Step S216: In the checkout mode, the POS terminal 20 determines whether or not the clerk-side scanner section 212 has read the clerk code. If it is determined that the store clerk code has been read (step S216: YES), the process proceeds to step S220. On the other hand, if it is determined that the clerk code has not been read (step S216: NO), the process proceeds to step S218.

Step S218: If the clerk code has not been read, the POS terminal 20 determines whether or not the end (receipt) button BT40 has been operated on the settlement screen (see FIG. 12C) (that is, whether or not the settlement has ended). judge. If the end (receipt) button BT40 is not operated and the settlement process is not completed (step S218: NO), the POS terminal 20 continues the processes of steps S214 to S216. On the other hand, when the end (receipt) button BT40 is operated (step S218: YES), the POS terminal 20 causes the customer-side display unit 205 and the store clerk-side display unit 210 to transition to the change screen and the receipt screen in order. Exit checkout mode. After ending the settlement mode, the POS terminal 20 transitions the customer-side display section 205 and the salesclerk-side display section 210 to the registration start screen (see FIG. 11A), and waits for the next customer's operation.

Step S220: If it is determined in step S216 that the salesclerk code has been read, the POS terminal 20 causes the display on the salesclerk side display section 210 to transition from the checkout screen to the salesclerk operation screen (see FIG. 13). Here, the display on the customer-side display unit 205 remains the checkout screen. For example, on the store clerk operation screen, the store clerk can collectively cancel all transaction details (registered details) that are being settled, or correct a part of the registered details. That is, the POS terminal 20 temporarily shifts to the registration mode operated by the store clerk. Then, the process proceeds to step S222.

Step S222: The POS terminal 20 determines whether or not the "cancel" button (see FIG. 13) has been operated on the clerk operation screen (that is, whether or not the registration has been canceled). If it is determined that the "cancel" button has been operated (step S222: YES), the transaction contents (registered contents) being settled are collectively canceled and the registration mode ends. Then, the POS terminal 20 causes both the customer-side display section 205 and the salesclerk-side display section 210 to transition to the registration start screen (see FIG. 11A), and returns to the process of step S200. On the other hand, if it is determined that the "cancel" button has not been operated (step S222: NO), the process proceeds to step S224.

Step S224: The POS terminal 20 determines whether or not the "custody/cash total" button has been operated on the clerk operation screen (that is, whether or not product registration has been completed). Here, if there is a correction to the transaction details (registered details) that have been made before the end of product registration, the clerk can make the correction by operating the clerk operation screen. For example, by operating the "Specified Correction" button or the "Immediately Correction" button (see FIG. 13), a correction screen is displayed, and the contents of transactions (registered contents) up to that point can be corrected. If the "custody/cash total" button has not been operated (step S224: NO), the POS terminal 20 continues the processing of steps S220 to S222. On the other hand, if it is determined that the "receipt/cash total" button has been operated on the clerk operation screen (step S224: YES), the POS terminal 20 terminates the temporary registration mode by the clerk's operation and proceeds to step S214. Proceed to processing and shift to settlement mode again. That is, both the customer-side display section 205 and the clerk-side display section 210 of the POS terminal 20 display the same checkout screen. As a result, the POS terminal 20 can perform settlement processing for partially corrected transaction details (registered details). Also, even if there is no correction to the transaction details (registration details), it returns to the beginning of the settlement mode, so it is possible to change the payment method once decided during settlement.

As described above, according to the present embodiment, it is possible to appropriately control the display contents on the screens of the store clerk and the customer depending on the conditions. For example, in the full self mode, in normal operations such as the registration mode and the payment mode, the screen displays on the clerk side and the customer side are controlled to have similar display contents (display contents corresponding to each operation mode), and the clerk When the code is read by the clerk-side scanner unit 212, the display of the clerk's screen can be controlled to the clerk's operation screen, so the display of the clerk's and customer's screens can be appropriately controlled. That is, according to this embodiment, it is possible to appropriately control the display contents on the screens of the store clerk and the customer depending on the conditions. In addition, at the timing when the store clerk operates, the store clerk side screen can be controlled to a store clerk operation screen different from the display contents of the customer side screen. In addition, when the clerk operates, it is possible to display that the operation is not possible on the customer side screen and control the clerk side screen to the clerk operation screen that can be operated by the clerk. display can be appropriately controlled.

In the above example, the POS terminal 20 controls the customer-side display unit 205 to show the registration screen or the checkout screen while the clerk-side display unit 210 is controlled to display the clerk operation screen. , the operation to display the registration screen or the checkout screen of the customer-side display unit 205 may not be accepted. In addition, when the POS terminal 20 controls the display of the clerk-side display unit 210 to the clerk operation screen, the customer-side display unit 205 is displayed as a pause screen (see FIG. 12F) or a message such as "please wait". You may control to the standby screen etc. which are displayed (refer FIG.16(C) mentioned later).

In the above example, the POS terminal 20 controls the display of the clerk-side display unit 210 to the clerk operation screen when the clerk-side scanner unit 212 reads the clerk-side code. In the case of reading, the display of the store clerk side display unit 210 may be similarly controlled to the store clerk operation screen. Further, the POS terminal 20 controls the display of the salesclerk side display unit 210 to the salesclerk operation screen when the salesclerk side scanner unit 212 reads the salesclerk code, and controls the display of the salesclerk side display unit 210 to the salesclerk operation screen when the customer side scanner unit 206 reads the salesclerk code. The display of the customer-side display unit 205 may be controlled to the clerk operation screen.

Further, in the above example, the display of the clerk side display unit 210 transitions to the clerk operation screen by reading the clerk code. A specific number of touch operations) or a preset password may be entered to transition to the clerk operation screen.

In addition, the POS terminal 20 is operated by the customer in the full self mode, but if a certain period of time or more has passed since the operation was started, or if the customer has not operated the POS terminal 20 for a certain period of time or more, the customer side The mirror display between the display unit 205 and the store clerk side display unit 210 may be canceled and the store clerk side display unit 210 may display a message such as "Please speak to the customer." As a result, the POS terminal 20 allows the store clerk to confirm whether the customer is confused about the operation, and the registration or settlement process can proceed smoothly.

The POS terminal 20 may control the customer-side display section 205 to display the salesclerk operation screen while controlling the display of the salesclerk-side display section 210 to the salesclerk operation screen. At this time, the POS terminal 20 may not accept any operation on the clerk operation screen of the customer-side display unit 205 .

(Display accompanied by store clerk's operation when an error occurs)
Next, the display of the POS terminal 20 when an error occurs in the full self mode will be described. The error includes, for example, an offline error of the change dispenser 209, an error of the change dispenser 209 when issuing a receipt, a near full/near end of the change dispenser 209, and the like. The cause of the offline error of the change dispenser 209 includes, for example, the disconnection of the connection cable of the change dispenser 209 . The cause of the error in the change dispenser 209 when issuing a receipt includes, for example, a shortage of receipt paper to be printed and issued by the printing unit 213 . Near full/near end of the change dispenser 209 includes cases where the money in the change dispenser is full (near full) or insufficient (near end).

(Display in case of offline error of change machine 209)
First, the display in the case of the offline error of the change dispenser 209 will be described. When an offline error occurs in the change dispenser 209 in the full-self mode, the POS terminal 20 controls both the customer-side display section 205 and the store clerk-side display section 210 to display an error screen.
FIG. 16 is a diagram showing a display example regarding a change dispenser offline error. FIG. 16A is an example of an error screen displayed when a change machine offline error occurs, and is a clerk call screen (here Then, "We are calling the clerk. Please wait a moment.") is displayed.

16(A) is displayed, the POS terminal 20 can perform a specific operation (for example, a touch operation to a specific position on the screen, a specific number of touch operations, a clerk code reading, password input, etc.), an error content screen displaying error content, countermeasures, etc. is displayed on the clerk side display unit 210 .

FIG. 16B is an example of an error content screen. In the illustrated example, a dialog screen DG50 containing information indicating the cause of the error (here, "the change machine is not connected") and a confirmation button BT50 is displayed as the error content screen. If this dialog screen DG50 is displayed, it is highly likely that the connection cable of the change dispenser 209 is disconnected. The confirmation button BT50 is an operation button for canceling the error and returning to the display screen before the occurrence of the error after the clerk confirms the contents of the error and takes measures (for example, inserting the connection cable of the change dispenser 209).

For example, after the clerk confirms the displayed error contents and takes measures (for example, inserts the connection cable of the change dispenser 209), when the confirmation button BT50 is operated, the POS terminal 20 confirms that the cause of the error has been taken care of. After confirming that it is, the error is canceled and the display screen before the error occurrence is restored. Note that if the clerk operates the confirmation button BT50 without taking action on the content of the error, the POS terminal 20 continues to display the dialog screen DG50, or hides the dialog screen DG50 once and then displays it again.

In addition, when the POS terminal 20 displays the error content screen (dialog screen DG50) on the clerk side display section 210, the customer side display section 205 displays a pause screen (see FIG. 12(F)) or "Please wait." or the like may be displayed on the standby screen. FIG. 16C is a diagram showing a display example of the standby screen.

Next, the operation of screen control processing by the POS terminal 20 when an error occurs will be described with reference to FIG. FIG. 17 is a flowchart showing an example of screen control processing when an error occurs.

Step S300: The POS terminal 20 determines whether or not an error has occurred. If no error has occurred (step S300: NO), this determination process continues. If YES), the process proceeds to step S302.

Step S302: When an error occurs, the POS terminal 20 causes the displays on the customer-side display section 205 and the salesclerk-side display section 210 to transition to an error screen (see FIG. 16A). Then, the process proceeds to step S304.

Step S304: The POS terminal 20 determines whether or not the clerk-side scanner section 212 has read the clerk code. If it is determined that the clerk code has not been read (step S304: NO), the POS terminal 20 continues this determination process, and if it is determined that the clerk code has been read (step S304: YES), Proceed to processing.

Step S306: The POS terminal 20 causes the store clerk side display section 210 to display an error content screen (see FIG. 16B), and the customer side display section 205 to transition to a standby screen (see FIG. 16C). Then, the process proceeds to step S308.

Step S308: The POS terminal 20 determines whether or not the confirmation button BT50 on the error content screen (dialog screen DG50) has been operated. If it is determined that the confirmation button BT50 has not been operated (step S308: NO), the POS terminal 20 continues this determination process, and if it is determined that the confirmation button BT50 has been operated (step S308: YES), the process proceeds to step S310.

Step S310: When the confirmation button BT50 is operated, the POS terminal 20 determines whether or not the cause of the error has been dealt with. If it is determined that the cause of the error has not been dealt with (step S310: NO), the POS terminal 20 returns to the process of step S306, and continues to display the error content screen (see FIG. 16B) on the clerk-side display section 210. Then, the customer-side display unit 205 displays a standby screen (see FIG. 16C). On the other hand, if it is determined that the cause of the error has been dealt with (step S310: YES), the POS terminal 20 proceeds to the process of step S312.

Step S312: The POS terminal 20 cancels the error, and returns the salesclerk side display section 210 and the customer side display section 205 to the display screens before the error occurred.

(Display when an error occurs in the change machine 209 when issuing a receipt)
Next, the display when an error occurs in the change dispenser 209 when a receipt is issued will be described. FIG. 18 is a diagram showing a display example of an error content screen when an error occurs in the change dispenser 209 when issuing a receipt. This figure corresponds to the error content screen shown in FIG. In the illustrated example, information indicating the cause of the error (here, "The change machine (change bill machine) is in an abnormal state. Please check the change machine (change bill machine) state."), A dialog screen DG60 including a confirmation button BT60 is displayed as an error content screen.

Screen control processing when an error occurs in the change dispenser 209 when issuing a receipt is basically the same processing as the screen control processing shown in FIG. A display example shown in FIG. 18 is displayed on the error content screen. For example, when the end (receipt) button BT40 is operated on the settlement screen (payment determination screen) shown in FIG. (step S300: YES), the POS terminal 20 displays an error screen (clerk call screen) shown in FIG. While the clerk call screen is displayed, the POS terminal 20 performs a specific operation (for example, a touch operation on a specific position on the screen or a specific number of touch operations, reading of a clerk code, input of a password, etc.). ) is received (step S304 in FIG. 17: YES), the error content screen shown in FIG. 18 is displayed on the clerk-side display unit 210 (step S306 in FIG. 17). On the other hand, when the POS terminal 20 displays the error content screen on the clerk side display section 210, the customer side display section 205 displays a pause screen (see FIG. 12F) or "please wait". You may control to the standby screen etc. (step S306 of FIG. 17). If it is determined that the confirmation button BT60 has been operated (step S308 of FIG. 17: YES), the POS terminal 20 determines whether or not the cause of the error has been dealt with (step S310 of FIG. 17). . If it is determined that the cause of the error has been dealt with (step S310: YES), the POS terminal 20 cancels the error, and returns the store clerk side display section 210 and the customer side display section 205 to the display screens before the error occurred. (Step S312 in FIG. 17).

(Display when a near-full or near-end error occurs in the change dispenser 209)
Next, display when a near-full/near-end error occurs in the change dispenser 209 will be described. FIG. 19 is a diagram showing a display example of an error content screen when a near-full/near-end error occurs in the change dispenser 209. As shown in FIG. 19A and 19B are display examples of the error screen, and FIG. 19C is a display example of the error content screen. Specifically, FIG. 19A is a display example of an error screen in the case of near-full. On the other hand, FIG. 19B is a display example of an error screen in the case of near-end. Here, "near full" means that the amount of change in the change dispenser 209 exceeds a predetermined first threshold value, and even if the amount of change in the change dispenser 209 does not exceed the full amount, the state is just a little away from the full state. (state in which it may not be possible to receive depending on the amount of money invested). Similarly, the near-end state is when the amount of change in the change dispenser 209 is less than the predetermined second threshold, and the state of no change is a state just short of the state of no change (depending on the amount of change, it may be insufficient). possible states). When a near-full/near-end error occurs in the change dispenser 209 , this error screen is displayed on both the clerk-side display section 210 and the customer-side display section 205 .

On the error content screen shown in FIG. 19(C), information indicating error cancellation "Do you want to return to the main menu?" is displayed. When the clerk changes the amount of change in the change dispenser 209 to eliminate the near-full or near-end state, the error can be canceled by operating the "yes" button BT70.

As described above, according to the present embodiment, when an error occurs, the display of the store clerk side and customer side screens is similarly controlled to the error screen, and when the store clerk operates to deal with the error, Display contents suitable for each of the store clerk's screen and the customer's screen can be made different. For example, when a clerk operates to deal with an error, the clerk's screen is controlled to an error content screen that displays the cause of the error and how to deal with it, and the customer's screen cannot be operated. is displayed, it is possible to appropriately control the display of the screens on the clerk side and the customer side. Also, at this time, information on how to deal with the error may be displayed on the screen of the clerk, so that the clerk can deal with the error while referring to the information about how to deal with the error displayed on the screen. will be able to

In the above example, the POS terminal 20 controls the display of the clerk-side display unit 210 to the error content screen when the clerk-side scanner unit 212 reads the clerk-side code. In the case of reading, the display of the store clerk side display unit 210 may be similarly controlled to the error content screen. Further, the POS terminal 20 controls the display of the clerk-side display unit 210 to an error content screen when the clerk-side scanner unit 212 reads the clerk-side code, and when the customer-side scanner unit 206 reads the clerk-side code, The display of the customer-side display unit 205 may be controlled to display an error content screen.

In the above example, when the clerk code is read, the POS terminal 20 controls only the display of the clerk side display section 210 to the error content screen, but controls only the display of the customer side display section 205 to the error content screen. You may Further, when the clerk code is read, the POS terminal 20 may control the display of both the clerk-side display section 210 and the customer-side display section 205 to the error content screen. Also, these controls may be performed based on the content of the error. For example, in the case of an offline error, near full or near end of the change machine 209, the clerk needs to deal with the error from the customer side display unit 205 side, so the POS terminal 20 only displays the customer side display unit 205. You may control to the error content screen. Alternatively, in this case, the POS terminal 20 may control the display of both the store clerk-side display section 210 and the customer-side display section 205 to the error content screen. In the case of an error when issuing a receipt, for example, if the cause is a shortage of paper, it is necessary to set paper. However, paper can be set by either the store clerk or the customer by changing the orientation of the printing unit 213. Therefore, the POS terminal 20 may control the display of both the clerk-side display section 210 and the customer-side display section 205 to the error content screen. When the change dispenser 209 is near-full or near-end, the POS terminal 20 displays a warning display on the clerk-side display unit 210 before transitioning to the error screen (just before reaching near-full or near-end). Either or both of the customer-side display units 205 may be displayed.

In the above example, the display of the clerk-side display unit 210 transitions to the error content screen by reading the clerk code. A specific number of touch operations) or a preset password may be entered to transition to the clerk operation screen.

In addition, when the method of coping with an error is displayed on the error content screen, not only an explanation, illustration, or photograph of the method of coping with the error, but also a moving image explaining the method of coping with the error may be displayed.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to the above-described embodiments, and includes design and the like within the scope of the gist of the present invention.
For example, when displaying the clerk operation screen on the clerk-side display unit 210, the POS terminal 20 displays a screen obtained by reducing the entire screen of the customer-side display unit 205, and at least a part of the reduced screen is displayed by the clerk. It is also possible to display the display contents for the clerk and various buttons for the clerk's operation. For example, the POS terminal 20 displays the reduced screen on the upper side and right side of the screen of the store clerk side display unit 210, and displays for the store clerk in the remaining areas (L-shaped areas) on the left side and the lower side. Contents and various buttons for clerk operation may be displayed. Furthermore, the POS terminal 20 may control the display on the clerk-side display section 210 according to the severity of the error or warning. For example, regarding the display on the clerk-side display unit 210, in the case of an error or warning with a low degree of severity, the POS terminal 20 displays the display contents for the clerk and various buttons for clerk operation at least around the reduced screen. It is displayed in a part (for example, an L-shaped area), and in the case of a serious error or warning, the display contents for the clerk and various buttons for clerk operation are displayed on the entire screen ((Fig. 13 or Fig. 13). 14), the degree of severity is set in advance according to the content of the error or warning, for example.

When the POS terminal 20 displays the same display content as the display content displayed on the customer-side display unit 205 on the salesclerk-side display unit 210, the button for canceling the error or warning is displayed on the customer-side display unit 205. It may be added and displayed in the same display layout as the screen.

When the POS terminal 20 displays the same display content as the display content displayed on the customer-side display unit 205 on the salesclerk-side display unit 210, the display layout similar to the screen on the customer-side display unit 205 is displayed. , the clerk side operation screen (see FIG. 13 or FIG. 14) may be displayed as a child screen. That is, displaying the same display content as the display content displayed on the customer-side display unit 205 also on the store clerk-side display unit 210 means that a child screen is displayed in a part of the same display layout as the screen of the customer-side display unit 205. may include displaying the store clerk side operation screen (see FIG. 13 or 14). It should be noted that what is displayed on the child screen is not limited to the reduced version of the clerk side operation screen shown in FIG. 13 or FIG. Any display mode may be used. When the POS terminal 20 satisfies a specific condition (a specific operation, reading of a store clerk code, etc.), the display on the store clerk side display unit 210 is changed to the screen of the customer side display unit 205 and the child screen of the store clerk side. The size relationship of the display size with the operation screen may be reversed. That is, when a specific condition is satisfied, the POS terminal 20 controls the clerk-side display unit 210 to a clerk-side operation screen (a screen on which display contents for the clerk and various buttons for clerk operation are displayed), The screen of the customer-side display unit 205 may be displayed as a child screen in a part of the display layout of the salesclerk-side operation screen. Note that the operation buttons displayed in the child screen may simply be displayed without receiving any operation.
