It is a flowchart which showed the basic flow of operation of a POS terminal 20.

In the following description, as a different aspect from the above-mentioned classification of the four operation modes, the POS terminal 20 sets the mode for executing the product registration process as the registration mode and the mode for executing the settlement process as the accounting mode (or settlement). Mode) may be referred to.

(Normal mode)
As shown in FIG. 5A, the normal mode is an operation mode in which the clerk side executes the registration process and the customer side executes the settlement process. That is, as shown in FIG. 5B, in the normal mode, the clerk side is in the registration mode and the customer side is in the accounting mode. That is, the POS terminal 20 operates as a registration accounting mode when viewed throughout the registration process to the settlement process.

In the normal mode, the clerk registers the customer's purchased product on the clerk side (the clerk side scanner unit 212, the clerk side display unit 210, the key operation unit 211). That is, the POS terminal 20 executes the registration process of the purchased product by the operation of the clerk (the operation of the clerk side scanner unit 212, the 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 the purchased products on the clerk side display unit 210, inserts money into the change machine 209, or operates the card settlement unit 208 to settle the payment (FIG. 5). Lower part of (A)). That is, the POS terminal 20 executes the settlement process by the customer's operation (inserting money into the change machine 209, operating the card settlement unit 208) (lower part of FIG. 5A).

That is, in the normal mode, as shown in FIG. 5B, the product is initially scanned by the clerk side 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 clerk side display unit 210 or the subtotal key arranged on the key operation unit 211) (step S30: YES), on the customer side, for example, the change machine 209 Settlement is performed by (step S50), and the process is completed.

The customer may wait until the registration process by the clerk is completed (until the total amount is fixed), 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).

In addition, the clerk may wait until the customer's payment is completed (until the customer picks up the change or receipt), but may register the next customer's purchased product. That is, the POS terminal 20 can register the purchased product of the next customer during the settlement process (lower part of FIG. 5A). In addition, the clerk may be absent during the payment by the customer (lower part of FIG. 5A). That is, the reception of the customer may be completed during the settlement of the customer.

In addition, the POS terminal 20 controls the payout of change / fishing bills by the change machine 209 in order to prevent forgetting to take the change when there is change, and detects that the customer has removed the change / fishing bills, etc. Issuance of the receipt by the printing unit 213 is controlled after recognizing in. 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 clerk in front of the customer who receives the change, but when there is a clerk, the above-mentioned control is not always performed. You may (that is, you may pay out the change / fishing bill and issue the receipt at the same time, or you may issue the receipt first). Further, the timing of paying out change / fishing bills 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 side executes the registration process and the customer side executes the settlement process. That is, as shown in FIG. 6B, in the case of the full self mode, the customer side is in both the registration mode and the accounting mode. That is, the POS terminal 20 operates as a registration accounting mode when viewed throughout the registration process to the settlement process.

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

When the registration process is completed, the customer confirms the total amount of the 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 payment (FIG. 6 (A). ) Lower). That is, the POS terminal 20 executes the settlement process by the operation of the customer (inserting money into the change machine 209, operating the card settlement unit 208) (lower part of FIG. 6A).

That is, in the full self mode, as shown in FIG. 6B, the product is scanned or the like by, for example, the customer side scanner unit 206 (step S20: YES), and the product is registered (step S21). After pressing the registration completion key (for example, the registration completion key displayed on the customer side display unit 205) (step S40: YES), payment is performed on the customer side 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 the clerk side does not mean that nothing can be done. That is, even when the POS terminal 20 is operating in the full self mode, the clerk code can be scanned by the clerk side scanner unit 212. Further, the POS terminal 20 can display various information (for example, a list described in FIG. 15) on the clerk side display unit 210 even when operating in the full self mode.

(Double scan mode)
As shown in FIG. 7A, the double scan mode is an operation mode in which the registration process is executed on both the clerk side and the customer side, and the settlement process is executed on the customer side. That is, as shown in FIG. 7B, in the double scan mode, both the clerk side and the customer side are in the registration mode, and the customer side is in the accounting mode. That is, the POS terminal 20 operates as a registration accounting mode when viewed throughout the registration process to the settlement process.

In the double scan mode, the clerk registers the purchased product on the clerk side (the clerk side scanner unit 212, the clerk side display unit 210, the key operation unit 211), and the customer registers the purchased product on the customer side (customer side scanner unit 212). 206, registered on the customer side display unit 205). That is, the POS terminal 20 can be used for clerk operations (scanning by the clerk side scanner unit 212, touching the clerk side display unit 210, pressing the key operation unit 211, etc.), customer operations, etc. (customer side scanner unit 206). (Scanning by, touching the customer side display unit 205), the registration process of the purchased product is executed (upper part of FIG. 7A).

When the registration process is completed, the customer confirms the total amount of the 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 payment (FIG. 7 (A). ) Lower). That is, the POS terminal 20 executes the settlement process by the customer's operation (inserting money into the change machine 209, operating the card settlement unit 208) (lower part of FIG. 7A).

That is, in the double scan mode, the product is initially registered on the clerk side and the customer side. For example, as shown in FIG. 7B, by scanning the scanner unit 212 on the clerk side (step S10: YES), registering the product (step S11), scanning the scanner unit 206 on the customer side (step S20: YES). YES), register the product (step S21).

After pressing the completion key or the like (step S41: YES), payment is performed on the customer side, for example, by the change machine 209 (step S50), and the process is completed.

The clerk may wait until the customer completes the payment (until the customer picks up the change or receipt), but may register the next customer's purchased product. That is, the POS terminal 20 can register the purchased product of the next customer during the settlement process (lower part of FIG. 7A). In addition, the clerk may be absent during the payment by the customer (lower part of FIG. 7A). That is, the reception of the customer may be completed during the settlement of the customer.

(Semi-self mode)
The semi-self mode is an operation mode by two or more POS terminals 20, and as shown in FIG. 8 (A), a clerk of at least one POS terminal 20 (the first POS terminal 20-1 in the example of FIG. 8). The registration process is executed on the side, and the settlement process is performed on the customer side of the other POS terminal 20 (one of the second POS terminal 20-2 and the third POS terminal 20-3 in the example of FIG. 8). The operation mode to execute. That is, in the semi-self mode, one or more (in the example of FIG. 8, one of the first POS terminals 20-1 as shown in FIG. 8B) is in the registration-only mode, and one or more of the other (FIG. 8). In this example, as shown in FIG. 8C, the second POS terminal 20-2 and the third POS terminal 20-3) are in the accounting-only mode.

In the semi-self mode, the clerk registers the customer's purchased product on the clerk side (the clerk side scanner unit 212, the clerk side display unit 210, the key operation unit 211) on the POS terminal 20 in the registration-only mode. That is, the POS terminal 20 executes the registration process of the purchased product by the operation of the clerk (the operation of the clerk side scanner unit 212, the clerk side display unit 210, the key operation unit 211, etc.) (upper part of FIG. 8A). ..

When the registration process by the clerk is completed, the customer moves to the POS terminal 20 in the accounting-only mode, confirms the total amount of the purchased products on the clerk side display unit 210, inserts money into the change machine 209, or makes a card payment. Operate unit 208 to settle (lower part of FIG. 8A). That is, the POS terminal 20 executes the settlement process by the customer's operation (inserting money into the change machine 209, operating the card settlement unit 208) (lower part of FIG. 8A).

When the registration process is completed at the registration-only mode POS terminal 20 (first POS terminal 20-1 in the example of FIG. 8), the customer changes from the registration-only mode POS terminal 20 to the accounting-only mode POS terminal 20 (FIG. 8). In the example, it moves to the second POS terminal 20-2), but the destination POS terminal 20 has information necessary for the settlement process (registration information generated in the first POS terminal 20-1 in the registration-only mode, etc.). Be supplied.

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

That is, in the semi-self mode, the product is first registered on the clerk side of the POS terminal 20 (first POS terminal 20-1) in the registration-only mode. For example, as shown in FIG. 8B, the product is registered (step S11) by scanning the scanner unit 212 on the clerk side (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 the accounting-only mode (for example, When either the second POS terminal 20-2 or the third POS terminal 20-3) is specified (step S31: YES), registration information is transmitted to the designated POS terminal 20 (step S32), and the registration-only mode The process at 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 the accounting-only mode (that is, the POS terminal 20 designated by the POS terminal 20 in the registration-only mode). Is settled on the customer side, for example, by the change machine 209 (step S50), and the processing at the POS terminal 20 in the accounting-only mode is completed.

After transmitting the registration information, the clerk can register the purchased product of the next customer (lower part of FIG. 8A). In addition, the clerk may be absent after transmitting the registration information (lower part of FIG. 8A).

(Notification of operation mode)
The POS terminal 20 notifies the current operation mode. For example, the current operation mode may be displayed on the clerk side display unit 210. Specifically, a screen having an operation mode display field may be displayed on the clerk side display unit 210, and the current operation mode may be displayed in the operation mode display field on the screen. The operation mode is displayed, for example, by the first registration button BT21 and the second registration button BT22, which will be described in detail later.

The operation mode of the POS terminal 20 shifts according to an explicit mode transition 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 the switching means in the CPU 201. Specifically, the key operation unit 211 includes a plurality of buttons, and according to the operation of the mode switching button 211a (see FIG. 3B) arranged at the uppermost stage and the rightmost end among the plurality of buttons. The operation mode shifts. Further, the operation mode of the POS terminal 20 shifts according to an operation other than the explicit mode shift operation by the clerk (for example, reading the clerk code). Further, the POS terminal 20 has predetermined conditions (conditions related to time such as elapsed time and predetermined time (schedule), conditions related to transmission / reception of information such as commands to and from other terminals, etc." that do not depend on the operation of the clerk. ) To shift the operation mode.

Since the mode switching button 211a is arranged at the corner of the key operation unit 211, it is possible to reduce operation mistakes when shifting the mode and to easily shift the operation mode. That is, when the mode switching button 211a exists at the corner of the key operation unit 211, for example, the mode switching button 211a which is the operation target is compared with the case where the mode switching button 211a exists near the center of the key operation unit 211. Since the number of other adjacent buttons is small, operation mistakes such as operating other buttons in a hurry are unlikely to occur, and the position of the mode switching button 211a to be operated can be instantly specified, so mode transition operation without stress. It can be performed.

Further, since the mode switching button 211a is arranged at the upper right corner (topmost and rightmost) of the key operation unit 211, the mode transition operation is performed not only when the clerk is on the clerk side but also when the clerk is on the customer side. It will be easier. That is, the clerk on the customer side cannot normally see each button of the key operation unit 211, but the mode switching button 211a existing at the upper right end of the key operation unit 211 is reached out from the customer side and groped. Since the mode switching button 211a, which is the operation target, can be easily recognized only by (feeling of the hand), the clerk on the customer side can perform the mode transition operation without moving to the clerk side. Further, since the mode switching button 211a is located at the uppermost stage and the rightmost end (outermost end) of the key operation unit 211, it is arranged at a close position when the clerk operates from the customer side, so that the clerk can easily operate the button 211a. It becomes.

In the present embodiment, the mode switching button 211a is arranged at the upper right corner of the key operation unit 211, but the mode can be recognized only by groping (a position that can be recognized relatively easily). The switching button 211a may be arranged at a position other than the upper right corner of the key operation unit 211, for example, at the lower right end. Also, instead of or in addition to arranging the mode switching button 211a at a position that can be recognized only by groping (for example, the corner at the upper right corner), it can be distinguished from other buttons even from the customer side. The mode switching button 211a may be formed on the surface. For example, the size of the mode switching button 211a may be different from the size of other buttons to the extent that it can be distinguished only by groping, or the shape of the mode switching button 211a may be different from the shape of other buttons. Alternatively, the height of the mode switching button 211a may be different from the height of the other buttons (for example, the mode switching button 211a may be projected more than the other buttons). ), The feel of all or part of the surface of the mode switching button 211a (the surface touched by the hand) may be different from the feel of other buttons (for example, only the surface of the mode switching button 211a is rough or rough. You may feel it, or you may provide protrusions or dents only on the surface of the mode switching button 211a).

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

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

(Transition from normal mode to full self mode)
The flowchart of FIG. 9A starts when the POS terminal 20 (normal mode) is in a non-use state (that is, starts when neither the clerk nor the customer is using it).

Step S100: Start timing the unused time.
Step S101: Determine whether or not the use has been started by a clerk or a customer. If the use has not been started, the process proceeds to step S102. When the use is started, the process proceeds to step S104.

Step S102: It is determined whether or not the unused time has elapsed a predetermined time (for example, a preset 10 minutes). When the predetermined time has elapsed, the process proceeds to step S103. If the predetermined time has not elapsed, the process returns to step S101.
Step S103: The operation mode is changed from the normal mode to the full self mode.
Step S104: Ends the timing of the unused time. Then, the flowchart of FIG. 9A ends.

When shifting to the full self mode, the store clerk may be notified that the mode has shifted to the full self mode (for example, information that there is an undelivered product is sent to the terminal carried by the clerk). .. Further, when the mode shifts to the full self mode, a message indicating or requesting the customer to self-register may be displayed on the customer side display unit 205.

Note that FIG. 9A shows the flow of transition from the normal mode to the full self mode, but the transition from the double scan mode to the full self mode is the same as the flow of FIG. 9 (A). It may be.

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

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

Step S111: The operation mode is changed 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 starts at all times (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 for declaring the transition to the semi-self mode (registration-only mode). For example, a button for declaring the transition to the semi-self mode (registration-only mode) may be displayed on the clerk side display unit 210, and it may be determined whether or not the button has been pressed (touched). If there is an operation, the process proceeds to step S121. If there is no operation, the flowchart of FIG. 10A ends.

Step S121: It is determined whether or not there is another POS terminal 20 operating in the semi-self mode in the POS system 1. As described above, in the case of 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. Therefore, for example, the POS terminal 20 is the first POS terminal 20-1. In this case, it is determined whether one of the second POS terminal 20-2 and the third POS terminal 20-3 operates in the semi-self mode (registration-only mode) and the other operates in the 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-only mode) has been designated. If specified, the process proceeds to step S123. If not specified, the process of step S122 is repeated.
Step S123: A transition instruction to the semi-self mode (accounting-only mode) is transmitted to the other designated POS terminal 20.

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

The operation in step S120 is performed when there is no other POS terminal 20 already operating in the semi-self mode and there is no other POS terminal 20 capable of shifting in the semi-self mode. Should not be possible.

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

Step S130: It is determined whether or not the transition instruction to the semi-self mode (accounting-only mode) has been received. When the transition instruction is received, the process proceeds to step S131. If the transition instruction has not been received, the flowchart of FIG. 10B ends.

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

Note that FIG. 10B shows the flow of the transition from the normal mode to the semi-self mode (accounting-only mode), but the transition from the full-self mode to the semi-self mode (accounting-only mode) is also shown in FIG. It may be the same as the flow of 10 (B).

Further, the transition of the operation mode may be executed based on a condition other than the transition instruction. For example, when the registration information is transmitted to the POS terminal 20 operating in the normal mode, the operation mode may be changed from the normal mode to the full self mode even if there is no movement instruction. Also. , When the POS terminal 20 receives the registration information, as the first condition, it is determined whether or not the operation mode switching is permitted, and when the operation mode switching is permitted, the operation mode is set. It may be migrated. Further, it may be determined whether or not the mode can be changed based on the current operation mode (situation) of the POS terminal that has received the registration information. For example, when the POS terminal 20 operating in the normal mode receives the operation mode switching information for switching the operation mode to the semi-self mode, and when the POS terminal 20 is on standby, the operation mode is received when the operation mode switching information is received. May be switched to the self mode, and when the POS terminal 20 is in the registration process or the settlement process, the operation mode may be switched to the semi-self mode after the registration process or the settlement process is completed. Such a transition instruction may be an operation that satisfies the conditions for switching the operation mode.

(Display in normal mode)
Subsequently, the display of the first POS terminal 20-1 in the normal mode will be described with reference to FIGS. 11 to 14. 11, 13, and 14 are display examples in the first POS terminal 20-1. FIG. 12 is an enlarged view of the first cash register button and the second cash register button. In the description of FIGS. 11 to 14, it is assumed that the second POS terminal 20-2 is in the full self mode and the third POS terminal 20-3 is in the normal mode.

FIG. 11 is a display example on the registration screen displayed on the clerk side display unit 210 of the first POS terminal 20-1. Specifically, FIG. 11 shows the display contents of the registration screen in the scene where two items of goods (asparagus) are registered.

The subtotal button BT10 at the lower right of the screen is a button for instructing the end of product registration. The clerk operates (touches) the subtotal button BT10 after the product registration is completed. The pause button BT11 is a button for suspending the own terminal (first POS terminal 20-1). The clerk operates the pause button BT11 when he / she leaves his / her terminal (for example, when he / she goes to search for a product or does not use it for a while).

In FIG. 11, the first cash register button BT21 and the second cash register button BT22 are displayed at the lower center of the screen. The first cash register button BT21 and the second cash register button BT22 are buttons for handing over the registration process to another POS terminal 20 (second POS terminal 20-2 or third POS terminal 20-3) that performs settlement processing.

As shown in FIG. 12, the first register button BT21 has a first operation mode display area BT21A, a first status display area BT21B, a first operating state display area BT21C, a first registration number display area BT21D, and a first not yet. The settlement transaction number display area BT21E is provided. In the first operation mode display area BT21A, the operation mode of the second register (second POS terminal 20-2) corresponding to the first register button BT21, here, the character "full self" indicating the full self mode is displayed. .. In the first operation mode display area BT21A, for example, characters of "normal" and "semi-self" are displayed in addition to "full self". When the character "normal" is displayed in the first operation mode display area BT21A, the operation mode of the second POS terminal 20-2 is the normal mode, and when the character "semi-self" is displayed, the second POS terminal The operation mode of 20-2 is the semi-self mode. In the normal mode, the registration process is performed on the clerk side, and in the full self mode, the registration process is performed on the customer side. Further, in the semi-self mode, the clerk can perform the registration process in the registration-only mode, and the registration process is not performed in the accounting-only mode. By displaying the operation mode on the first cash register button BT21, the clerk is informed whether the registration process on the clerk side and the registration process on the customer side of the second POS terminal 20-2 are performed together with the operation mode in the second POS terminal 20-2. I am informing you. In addition, even if the characters such as "registration only" and "accounting only" are displayed instead of the characters "semi-self" to clearly notify whether the semi-self mode is the registration-only mode or the accounting-only mode. Good.

In the first status display area BT21B, the status of the second POS terminal 20-2, here, "excessive change" is displayed, and the change machine 209 of the second POS terminal 20-2 is displayed as near full. In the first status display area BT21B, each character of "normal", "insufficient change", and "out of receipt" is displayed. When the character "normal" is displayed, no status abnormality has occurred in the second POS terminal 20-2. Further, when the characters "insufficient change" are displayed, the change of the change machine 209 is near-end, and when "out of receipt" is displayed, the receipt paper of the printing unit 213 is insufficient. In addition, other information, for example, that the receipt paper is near-end, may be displayed in the first status display area BT21B.

In the first operating status display area BT21C, the operating status of the second POS terminal 20-2, here "waiting" is displayed, and neither the registration process nor the settlement process is performed in the second POS terminal 20-2. It is shown that the 2POS terminal 20-2 is in the standby state. In the first operating state display area BT21C, in addition to "waiting", each character such as "registering", "paying", "offline", and "calling a clerk (CALL)" is displayed. When the characters "registering" are displayed, the registration process is being performed on the second POS terminal 20-2. When the characters "payment in progress" are displayed, the change machine 209 cannot send / receive information to / from the second POS terminal 20-2 when "offline" in which the payment process is being performed is displayed. ing.

In the first cash register number display area BT21D, the cash register number of the cash register to be displayed, here, the characters of the second cash register (right) indicating the second POS terminal 20-2 are displayed. Since the second POS terminal 20-2 is arranged on the right side of the first POS terminal 20-1, it is displayed as "right". In the first unsettled transaction number display area BT21E, the number of unsettled transactions among the registration information transmitted to the second POS terminal 20-2, here "0", is displayed. By confirming the first unsettled transaction number display area BT21E, the clerk determines the POS terminal to which the registration information is transmitted.

Similarly, the second cash register button BT22 has a second operation mode display area BT22A, a second status display area BT22B, a second operating state display area BT22C, a second cash register number display area BT22D, and a second unsettled transaction number display. Region BT22E is provided. These displays are almost the same as those of the first cash register button BT21. The POS terminal 20 transmits information on the status of the own terminal, the operating status, and the number of unsettled transactions to the other POS terminals 20 in the POS system 1.

The first cash register button BT21 is a button for transmitting the registration information for which the product has been registered on the first POS terminal 20-1 to the second cash register (second POS terminal 20-2 in FIG. 1), and is a second cash register button. The BT 22 is a button for transmitting the registration information for which the product has been registered at the first POS terminal 20-1 to the third cash register (third POS terminal 20-3 in FIG. 1). So to speak, the first cash register button BT21 and the second cash register button BT22 are buttons for selecting (designating) a POS terminal for transmitting registration information.

The clerk operates (presses) the first cash register button BT21 when selecting the second POS terminal 20-2 as the terminal for executing the settlement process. When the operation (pressing) of the first cash register button BT21 is accepted, the first POS terminal 20-1 transmits the registration information to the second POS terminal 20-2. When the first POS terminal 20-1 transmits the registration information to the second POS terminal 20-2, the registration information is inherited from the first POS terminal 20-1 to the second POS terminal 20-2. The clerk operates (presses) the second cash register button BT22 when selecting the third POS terminal 20-3 as the terminal for executing the settlement process. When the operation (pressing) of the second cash register button BT22 is accepted, the first POS terminal 20-1 transmits the registration information to the third POS terminal 20-3. When the first POS terminal 20-1 transmits the registration information to the third POS terminal 20-3, the registration information is inherited from the first POS terminal 20-1 to the third POS terminal 20-3.

The first cash register button BT21 is a button for transmitting registration information to the second POS terminal 20-2, and the operation mode of the second POS terminal 20-2 is displayed on the first cash register button BT21. As described above, the first cash register button BT 21 serves as a means for selecting the second POS terminal 20-2 as the POS terminal 20 for transmitting registration information and also as a means for displaying the operation mode of the second POS terminal 20-2. Similarly, the second cash register button BT22 serves as a means for selecting the third POS terminal 20-3 as the POS terminal 20 for transmitting registration information and also as a means for displaying the operation mode of the third POS terminal 20-3.

Further, when the predetermined transmission prohibition condition is satisfied for the other POS terminal, for example, when the transmission prohibition condition is satisfied for the second POS terminal 20-2, the first registration button BT21 is grayed out and displayed. Or the first cash register button BT21 may not be displayed. Note that graydown refers to a display in which the brightness is relatively lower than other areas on the screen. On the other hand, the active display is a display having the same brightness as other screens on the screen or a display brighter than other screens, and at least a display brighter than a graytown display.

FIG. 13 is a display example on the subplanning surface displayed on the clerk side display unit 210 of the first POS terminal 20-1. Specifically, FIG. 13 shows the display contents of the subplanning surface in the scene following the scene of FIG. 11 (the scene after the operation of the subtotal button BT10).

In FIG. 13, the current total button BT20, the first cash register button BT21, the second cash register button BT22, and the checkout ticket button BT25 are provided at the lower right of the screen. The current total button BT20 is a button for instructing the input of the deposit amount. When the clerk executes the settlement process on his / her own terminal (1st POS terminal 20-1), after receiving the deposit of the total amount or more from the customer (after inputting the deposit amount of the total amount or more), the clerk is the current total. Operate the button BT20.

The first cash register button BT21 and the second cash register button BT22 are buttons for transmitting registration information for settlement to another POS terminal 20 (second POS terminal 20-2 or third POS terminal 20-3). By pressing the first cash register button BT21 or the second cash register button BT22, the settlement process can be performed on the second POS terminal 20-2 or the third POS terminal 20-3. After operating the subtotal button 10, the first checkout button BT21 and the second checkout button BT22 may not be displayed on the premise that the settlement process is performed on the own terminal (first POS terminal 20-1). .. Alternatively, on the premise that the monastery of the registration information is not performed until the registration process is completed, the subtotal button BT21 and the second register button BT22 are not displayed before the subtotal button BT10 is operated. After operating the BT10, the first register button BT21 and the second register button BT22 may be displayed.

The checkout button BT25 is a button for causing the printing unit 113 to issue a checkout ticket. The clerk operates the checkout ticket button BT25 when the POS terminal 20 (second POS terminal 20-2 or third POS terminal 20-3) that has read the checkout ticket is made to execute the settlement process.

The information required to execute the settlement process is coded and printed on the bill. For example, the registration information itself used for the settlement process may be converted into a QR code (registered trademark) and printed on the checkout ticket, or information for specifying the registration information used for the settlement process (for example, transaction). Identification information, etc.) may be bar-coded and printed. When the registration information itself used for the settlement process is QR-coded, for example, when there are a plurality of lanes formed by grouping a plurality of POS terminals 20, the POS terminal 20 that issued the checkout ticket Payment can be made at the POS terminal 20 in a lane other than the included lane. Therefore, even if a failure such as offline occurs in the lane including the POS terminal 20 that issued the payment ticket, the settlement process can be performed. Further, when the POS terminal 20 is offline, cannot be transmitted / received, or cannot be used due to a communication failure in the lane including the POS terminal 20, the checkout button BT32 displayed by operating the subtotal button BT10 shown in FIG. May pop up or be displayed in a different mode. Specifically, the color may be changed, blinked, or grayed out as compared with the normal check button BT32.

In the aspect of issuing the accounting ticket printed with the QR code, the POS terminal 20 (second POS terminal 20-2 or third POS terminal 20-3) that has read the accounting ticket (QR code) is, for example, The settlement process is executed using the registration information obtained from the QR code. Further, in the embodiment in which the payment ticket printed with the above barcode is issued, the POS terminal 20 (second POS terminal 20-2 or third POS terminal 20-3) that has read the payment ticket (bar code) is, for example, A terminal (1st POS terminal 20-1, 2nd POS terminal 20-) that issued the accounting ticket is requested to acquire registration information including information (transaction identification information, etc.) for identifying the registration information obtained from the barcode. 2 or 3rd POS terminal 20-3), or a terminal that has acquired registration information from the terminal that issued the payment ticket. For example, by transmitting to the store controller 30 or the like, the registration information is received from the terminal that sent the registration information acquisition request, and the settlement process is executed. In other words, in the mode of issuing the accounting ticket printed with the above barcode, the terminal that issued the accounting ticket (first POS terminal 20-1, second POS terminal 20-2 or third POS terminal 20-3) or , The terminal (store controller 30, etc.) that has acquired the registration information from the terminal that issued the bill is from the POS terminal 20 (2nd POS terminal 20-2 or 3rd POS terminal 20-3) that has read the bill. When the transmitted registration information acquisition request is received, the registration information specified by the registration information acquisition request is transmitted to the transmission source of the registration information acquisition request (registration information request source).

The issued bill is handed to the customer by the clerk. After that, the customer moves to the POS terminal 20 (second POS terminal 20-2 or third POS terminal 20-3), and the POS terminal 20 (customer side scanner unit 206) reads the code on the accounting ticket. Based on this, the settlement process is executed at the POS terminal 20 (second POS terminal 20-2 or third POS terminal 20-3). Also, in combination with the registration screen button BT26, or instead of operating the registration screen button BT26, the subtotal button BT10 is pressed again, an area other than the send button in the display area is pressed, or the numeric keypad is pressed. The product registration screen may be returned by an operation not related to the next operation such as.

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

As described above, the current total button BT20 is a button to be operated after inputting the deposit amount equal to or more than the total amount, and FIG. 13 shows a scene in which the deposit amount equal to or more than the total amount is input. Absent. Therefore, in FIG. 13, similarly to the second cash register button BT22, the current total button BT20 may be displayed in a display mode indicating that the operation is not effective.

FIG. 14 is a display example on the settlement screen displayed on the clerk side display unit 110 of the first POS terminal 20-1. Specifically, FIG. 14 shows the display contents of the settlement screen in the scene following the scene of FIG. 13 (the scene after inputting the deposit amount “¥ 503” in a number. The scene before the operation of the current total button BT20). ing. The scene of FIG. 14 is a scene after inputting the deposit amount “¥ 503” of the total amount “¥ 383” or more, that is, the case where the settlement process is executed on the own terminal (first POS terminal 20-1). Therefore, the buttons (first cash register button BT21, second cash register button BT22, checkout ticket button) for causing the other terminal POS terminal 20 (second POS terminal 20-2 or third POS terminal 20-3) to execute the settlement process. BT25) is displayed in a display mode indicating that the operation is not valid.

In the scene of FIG. 11, when the current total button BT20 is operated, the change "¥ 120" is discharged from the change machine 109, and the printing unit 113 issues a receipt or the like.

On the customer side display unit 205 of the first POS terminal 20-1 in the normal mode, an image showing an explanation that money can be inserted while the clerk is performing the product registration process is displayed. The customer can insert money from the change machine 209 while the product is being registered. When the settlement process is started, a screen corresponding to the settlement process is displayed.

(Display in full self mode)
Subsequently, the display of the POS terminal 20 in the full self mode will be described with reference to FIGS. 15 and 16. 15 and 16 are display examples in the POS terminal 20 in the full self mode.

FIG. 15A is a display example of the registration start screen displayed on the customer side display unit 205 of the POS terminal 20 in the full self mode. In FIG. 15A, the 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 the 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 example shown in the figure, since Japanese is selected, a button for switching to English, Chinese, or Korean is displayed. For example, when English is selected, the registration start screen in English is displayed. Then, a button for switching to Japanese, Chinese, and Korean will be displayed. Further, the image GA01 on the lower side of the button BT37 shows the state of the No. 2 cash register (second POS terminal 20-2 in FIG. 1). The image GA02 on the right side of the image GA01 shows the state of the No3 cash register (third POS terminal 20-3 in FIG. 1).

When the customer operates the registration start button BT30, the POS terminal 20 shifts to the registration mode, and the display of the customer side display unit 205 shifts from the registration start screen to the registration screen.

FIG. 15B is a display example of the registration screen displayed on the customer side display unit 205 of the POS terminal 20 in the full self mode. In the illustrated example, on the right side of the registration screen, the product name, unit price, number of registered products (purchased points), and total amount of the registered products are displayed as registered contents. Here, the registered contents of the scene where two items of products (pear, apple) are registered are displayed. Immediately after the registration start button BT30 is operated on the registration start screen shown in FIG. 15A to shift to the registration screen, no product has been registered yet (initial state registration screen). Is displayed, but for convenience of explanation, FIG. 15B shows an example of a registration screen after the product has already been registered. Buttons BT35 to 37, images GA01, and GA02 are also displayed on the screen after the product is registered.

The 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 check button BT32 after completing the product registration, the POS terminal 20 shifts to the check mode and executes the checkout process. The clerk call button BT33 is a button for calling a clerk. The customer operates the clerk call button BT33 when calling the clerk (for example, when the clerk's support is required). When the customer operates the clerk call button BT33, for example, the clerk's mobile terminal is notified, a sound is output from the mobile terminal, or the mobile terminal vibrates. Further, when the customer operates the clerk call button BT33, a predetermined lamp (indicator lamp such as a barber's pole) installed in the store may be turned on.

As described above, the buttons BT35 to BT37 are buttons for switching the display language to English, Chinese, and Korean, respectively. Further, the "vegetable" button BT38 is a button for registering a product without a barcode (here, a vegetable) from a preset key. For example, when the customer operates the "vegetable" button BT38, a preset screen is displayed in which each of the vegetables can be registered by operating the preset key. In the illustrated example, only the "vegetable" button BT38 is illustrated, but instead of the "vegetable" button BT38, as a button for registering any product such as prepared foods and bread from the preset key, not limited to vegetables. , Or can be additionally displayed. In addition. The preset key is set in advance by a clerk or the like at the POS terminal 20.

When the customer operates the check button BT32, the POS terminal 20 shifts to the check mode, and the display of the customer side display unit 205 shifts from the registration screen to the checkout screen.

FIG. 16 is a display example of the settlement screen displayed on the customer side display unit 205 of the POS terminal 20 in the full self mode. FIG. 16A is a settlement screen (payment method selection screen) displayed when the settlement process is started. For example, the POS terminal 20 displays a payment method selection screen as shown in FIG. 16A when the payment button BT32 is operated on the registration screen (see FIG. 15B). On the illustrated payment method selection screen, the total payment amount (240 yen in this case), payment method options, and the like are displayed. As payment method options, cash, credit, electronic money, etc. are displayed as selectable operation buttons.

FIG. 16B is a settlement screen (payment screen) displayed when starting payment by cash. For example, the POS terminal 20 displays a deposit screen as shown in FIG. 16 (B) when cash is selected on the payment method selection screen (see FIG. 16 (A)). On 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 (240 yen here), the amount deposited (deposit amount), etc. are displayed on the right side of the screen. Will be done. FIG. 16C 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. 16C when cash (deposit) equal to or greater than the payment amount (purchase amount) is inserted. On the illustrated deposit decision screen, the payment amount (240 yen here), the amount put in (deposit amount, 250 yen here), change (10 yen here), etc. are displayed on the right side of the screen. On the left side of the screen, guidance for determining the deposit amount (here, "If you like, please 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 the settlement process based on the payment amount (here, 240 yen) and the deposit amount (here, 250 yen).

FIG. 16D 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. 16 (D) when the end (receipt) button BT40 is operated on the deposit determination screen (FIG. 16 (C)). On the illustrated change screen, an image prompting the receipt of change is displayed on the left side of the screen, and the payment amount (240 yen here) and the amount put in (deposit amount 250 here) continue on the right side of the screen. Yen), change (10 yen here), etc. are displayed.

FIG. 16E is a settlement screen (receipt screen) displayed when the change is removed. For example, the POS terminal 20 displays a receipt screen as shown in FIG. 16 (E) when change is removed from the outlet of the change machine 209. The POS terminal 20 may install a sensor such as a photo sensor in the vicinity of the outlet, and when the sensor recognizes an object (assuming a customer's hand), it may be determined that the change has been removed.

FIG. 16F is a pause screen displayed when the POS terminal 20 is in a hibernation state. That is, the POS terminal 20 is in the hibernate mode (hibernate state), but when it is in the hibernate mode, it displays a hibernate screen as shown in FIG. 16 (F).

The POS terminal 20 displays the registration start screen (FIG. 15 (A)) after the receipt screen (FIG. 16 (E)) is displayed. 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 be provided with a sensor capable of recognizing that the receipt has been removed from the issuing port.

If the input amount and the deposit amount are equal and no change is generated, the change screen (FIG. 16 (D)) is not displayed, and the deposit screen (FIG. 16 (C)) is displayed on the receipt screen (FIG. 16 (E)). )) May be transitioned.

As described above, in the full self mode, when the customer registers and pays for the product to be purchased, the POS terminal 20 displays the registration start screen and the registration screen shown in FIGS. 15 and 16 according to the progress and status of the operation. , The settlement screen and the like are displayed on the customer side display unit 205. Further, the POS terminal 20 causes the clerk side display unit 210 to display the same display content as the display content displayed on the customer side display unit 205. For example, the POS terminal 20 causes the clerk side display unit 210 to display the same screen as the screen of the customer side display unit 205 (so-called mirror display, mirroring display). It should be noted that displaying the same display contents is not limited to displaying exactly the same screen, but also includes that some display contents and layouts are different. For example, on the registration screen, the contents essential for the registration operation (for example, the product name, unit price, number of registered products (purchased points), total amount, and "vegetables" in FIG. 15 (B). If the button BT38, the checkout button BT32, etc.) are displayed on any of the display units, the same display contents may be displayed even if at least a part of the other display contents is different. ..

A mirror image of the image displayed on the customer side display unit 205 is displayed on the clerk side display unit 210 of the first POS terminal 20-1 in the full self mode, and the same image as the customer side display unit 205 is displayed. Further, a button for switching to the double scan mode may be displayed on the mirror image on the clerk side display unit 210.

(Display in semi-self mode)
The semi-self mode has an accounting-only mode and a registration-only mode. In the accounting-only mode, a predetermined standby screen is displayed on the clerk side display unit 210. Further, the customer side display unit 205 displays a predetermined standby screen until the registration information is transmitted from the other POS terminal 20, and after the registration information is transmitted, the settlement process in the full self mode is performed. An image similar to the previous image is displayed.

In the registration-only mode, a predetermined standby screen is displayed on the customer side display unit 205. A predetermined standby screen is displayed on the clerk side display unit 210 until the product registration is started, and after the product registration is started, the settlement process is performed from the registration process on the clerk side display unit 210 in the normal mode. An image similar to the one at the time of the event is displayed. In the semi-self mode, the settlement is not performed by the own device, so the current total key (see FIG. 13) may not be displayed.

(Judgment and display of operation mode of other POS terminals)
It is a flowchart which shows an example of the operation of a POS system 1. Specifically, the flowchart of FIG. 17 is a flowchart for determining the display mode of the first cash register button and the second cash register button in the first POS terminal 20-1. The left side of FIG. 17 shows the operation of the third POS terminal 20-3, the center shows the operation of the first POS terminal 20-1, and the right side shows the operation of the second POS terminal 20-2.

Step S211: The first POS terminal 20-1 confirms whether or not the transferable information has been received. As will be described later, the second POS terminal 20-2 and the third POS terminal 20-3 transmit the transferable information to the first POS terminal 20-1 when the registration information can be received in order to inherit the registration information. The first POS terminal 20-1 determines whether or not the transferable information is received.
Step S212: It is determined whether the second cash register (second POS terminal 20-2) can be taken over. Here, it is determined whether or not the second POS terminal 20-2 can be inherited based on whether or not the transferable information is received from the second POS terminal 20-2. When the second POS terminal 20-2 can be taken over, the process proceeds to step S213. When the second POS terminal 20-2 cannot be taken over, the process proceeds to step S214.
Step S213: The first POS terminal 20-1 actively displays the first cash register button BT21. By actively displaying the first cash register button BT21, it is possible to notify the second POS terminal 20-2 that transmission for taking over the registration information can be performed.
Step S214: The first POS terminal 20-1 displays the first cash register button BT21 in gray down. By displaying the first cash register button BT21 in gray down, it is possible to notify the second POS terminal 20-2 that transmission for inheriting the registration information cannot be performed.

Step S215: It is determined whether the third cash register (third POS terminal 20-3) can be taken over. Here, it is determined whether or not the third POS terminal 20-3 can be inherited based on whether or not the transferable information is received from the third POS terminal 20-3. When the third POS terminal 20-3 can be taken over, the process proceeds to step S216. When the third POS terminal 20-3 cannot be taken over, the process proceeds to step S217.
Step S216: The first POS terminal 20-1 actively displays the second cash register button BT22. By actively displaying the second cash register button BT22, it is possible to notify the third POS terminal 20-32 that transmission for taking over the registration information can be performed.
Step S217: The first POS terminal 20-1 displays the second cash register button BT22 in gray down. By displaying the second cash register button BT22 in gray down, it is possible to notify the third POS terminal 20-3 that the transmission for inheriting the registration information cannot be performed. Then, the flowchart of FIG. 17 ends.

Step S221: The second POS terminal 20-2 determines whether the current mode is the normal mode or the semi-self mode (registration-only mode). The second POS terminal 20-2 proceeds to step S222 when the current mode is the normal mode or the semi-self mode (registration-only mode). The second POS terminal 20-2 proceeds to step SS223 if the current mode is not the normal mode or the semi-self mode (registration-only mode).
Step S222: The second POS terminal 20-2 determines whether the clerk is performing the product registration process. The second POS terminal 20-2 ends the flowchart of FIG. 17 when the clerk is performing the product registration process. The second POS terminal 20-2 proceeds to step S223 when the clerk has not performed the product registration process.

Step S223: The second POS terminal 20-2 determines whether the current mode is the full self mode. The second POS terminal 20-2 proceeds to step S224 when the current mode is the full self mode. The second POS terminal 20-2 proceeds to step S225 if the current mode is not the full self mode.
Step S224: The second POS terminal 20-2 determines whether the customer is performing the product registration process. The second POS terminal 20-2 ends the flowchart of FIG. 17 when the customer is performing the product registration process. The second POS terminal 20-2 proceeds to step S225 when the clerk has not performed the product registration process.
Step S225: The second POS terminal 20-2 transmits the transferable information to the first POS terminal 20-1. The second POS terminal 20-2 notifies the first POS terminal 20-1 that it is ready to receive the registration information and perform the settlement process by transmitting the transferable information. The second POS terminal 20-2 transmits the transferable information not only to the first POS terminal 20-1 but also to the third POS terminal 20-3. Then, the flowchart of FIG. 17 ends.

Step S231: The third POS terminal 20-3 determines whether the current mode is the normal mode or the semi-self mode (registration-only mode). The third POS terminal 20-3 proceeds to step S232 when the current mode is the normal mode or the semi-self mode (registration-only mode). The third POS terminal 20-3 proceeds to step S233 when the current mode is not the normal mode or the semi-self mode (registration-only mode).
Step S232: The third POS terminal 20-3 determines whether the clerk is performing the product registration process. The third POS terminal 20-3 ends the flowchart of FIG. 17 when the clerk is performing the product registration process. The third POS terminal 20-3 proceeds to step S233 when the clerk has not performed the product registration process.

Step S233: The third POS terminal 20-3 determines whether the current mode is the full self mode. The third POS terminal 20-3 proceeds to step S234 when the current mode is the full self mode. The third POS terminal 20-3 proceeds to step S235 if the current mode is not the full self mode.
Step S234: The third POS terminal 20-3 determines whether or not the customer is performing the product registration process. The third POS terminal 20-3 ends the flowchart of FIG. 17 when the customer is performing the product registration process. The third POS terminal 20-3 proceeds to step S235 when the clerk has not performed the product registration process.
Step S235: The third POS terminal 20-3 transmits the transferable information to the first POS terminal 20-1. The third POS terminal 20-3 notifies the first POS terminal 20-1 that it is ready to receive the registration information and perform the settlement process by transmitting the transferable information. The third POS terminal 20-3 transmits the transferable information not only to the first POS terminal 20-1 but also to the second POS terminal 20-2. Then, the flowchart of FIG. 17 ends.

As described above, according to the present embodiment, in the POS terminal 20 (for example, the first POS terminal 20-1), the other POS terminal 20 (for example, the second POS terminal 20-2 and the third POS terminal 20-3) in the POS system 1). The operation mode of is displayed. Therefore, since the operation mode of the other POS terminal 20 in the POS system 1 can be grasped, the store clerk can allocate the customer to the POS terminal 20 capable of operating. Therefore, it is possible to efficiently operate a plurality of POS terminals.

Further, the POS terminal 20 (for example, the second POS terminal 20-2 and the third POS terminal 20-3) takes over the registration information for which the product has been registered from another POS terminal 20 (for example, the first POS terminal 20-1) and makes a payment. It is possible to process. Therefore, it is possible to suppress the situation where customers stay at one POS terminal 20, so that the settlement process can be smoothly performed.

Further, the POS terminal 20 (for example, the first POS terminal 20-1) may prohibit the transfer of the registration information to another POS terminal 20 (for example, the second POS terminal 20-2 or the third POS terminal 20-3). Therefore, since the registration process in the other POS terminal 20 can be prevented from being hindered, the registration process can be smoothly performed. Specifically, when the other POS terminal 20 (for example, the second POS terminal 20-2 or the third POS terminal 20-3) is in the registration mode or the semi-self mode registration-only mode and the clerk is performing the product registration process. Or, when the customer is performing the product registration process in the full self mode, the transfer of the registration information is prohibited. For this reason, the POS terminal 20 that inherits the registration information does not perform the registration process, so that the settlement can be started quickly, the place where the settlement is performed can be prevented from being confused, and the settlement process can be performed smoothly. Can be done.

Further, the POS terminal 20 (for example, the first POS terminal 20-1) sets the operation mode of the other POS terminal 20 (for example, the second POS terminal 20-2 or the third POS terminal 20-3) to the first register button BT21 and the second register. It is displayed on the button BT22. Since the first cash register button BT21 and the second cash register button BT22 are buttons for transmitting, the clerk sets the operation mode of the POS terminal (for example, the second POS terminal 20-2 or the third POS terminal 20-3) to be transmitted. You can perform the transmission process while watching. Therefore, the registration information can be easily taken over.

In the above example, the POS system 1 includes one POS terminal 20 of a first POS terminal 20-1, a second POS terminal 20-2, and a third POS terminal 20-3, but includes two POS terminals. It may be one equipped with four or more POS terminals. Further, the POS system 1 includes a store controller 10 other than the POS terminal 20, but may not include a store controller. In this case, a specific one or any one of the plurality of POS terminals 20 stores. It may have the same function as the controller.

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

Further, in the above example, the POS system 1 is configured to include a POS terminal 20 capable of performing both registration processing and settlement processing, but may be configured to include other POS terminals. .. For example, it may include a POS terminal that can perform registration processing but cannot perform settlement processing, or may include a POS terminal that cannot perform registration processing and can perform settlement processing. These POS terminals may be provided in place of the POS terminal 20 capable of performing both registration processing and settlement processing. Further, as the POS terminal for detecting the mode in the POS terminal 20 having a plurality of modes and notifying the detected mode, the POS terminal may be a POS terminal in which the registration process can be performed by the clerk and cannot be performed by the customer, or can be performed by the customer. A POS terminal (a POS terminal dedicated to full self) that cannot be used on the side may be used. Further, the settlement process may be a POS terminal that can be performed by the clerk or the customer, or a POS terminal that can be performed only by the clerk.

Further, in the above example, the POS terminal 20 includes one printing unit 213 that can rotatably change the direction from the clerk side to the customer side and from the customer side to the clerk side (direction of the medium issuing port). It may be provided with two printing units having a medium issuing port on the side of. That is, in the POS terminal 20, instead of one printing unit 213 that can rotatably change the direction of the medium issuing port, the clerk side printing unit having the medium issuing port on the clerk side and the medium issuing port on the customer side A certain customer-side printing unit may be provided separately.

Further, in the above example, the customer-side scanner unit 206 is of a type that the operator (clerk, customer) holds in his / her hand and approaches the object (product, etc.) to recognize the identification information. It may be of type. For example, it may be a fixed type that recognizes an object closer to it. The same applies to the scanner unit 212 on the clerk side.

Further, in the above example, when the operation mode is switched, the POS terminal 20 may display that the operation mode is switched on at least one of the customer side display unit 205 and the clerk side display unit 210. .. For example, when switching from full self mode to semi-self mode (accounting-only mode), when switching (or before switching), a predetermined time (for example, about several seconds) is displayed on the customer side display unit 205, such as "Switch to accounting-only mode". You may display a message. After switching the operation mode, it may be displayed that the operation mode has been switched.

In the full self mode in which the clerk is not logged in, the POS terminal 20 determines whether to maintain the full self mode, switch to the normal mode, or switch to the double scan mode when the clerk logs in. It may be decided according to the operation of the clerk (for example, button operation).

That is, in the full self mode in which the clerk is not logged in, the POS terminal 20 is set to a button for maintaining the full self mode, a button for switching to the normal mode, and a double scan mode when the clerk logs in. A button for switching may be displayed, and the operation mode after login may be controlled according to which button is operated. For example, when a clerk is asked to provide support for registering a product (when a clerk calls), the clerk operates a button to switch to normal mode after logging in to register the product. After that, if you are asked for support (when the customer calls you, but you also want the clerk to cooperate), the clerk will double-scan after logging in. If you operate the button to switch to the mode and log in for some reason (for example, check the processing status), but the customer wants to register himself or does not need the support of the clerk (or temporarily) If you just logged in to and cannot support your customers), the clerk operates a button to maintain full self mode after logging in. When maintaining the full self mode after the clerk logs in, the product name or the like of the product registered by the customer may not be displayed on the clerk side display unit 210 from the viewpoint of privacy or the like. However, information that does not affect privacy so much (cumulative amount during registration, etc.) may be displayed. By displaying the cumulative amount of money being registered, the clerk can appropriately confirm, for example, the right to draw a lottery (whether or not the purchase amount exceeds a predetermined amount, etc.), so that the lottery can be prepared in advance.

Further, when the power of the POS terminal 20 is turned on, the opening process may be performed. In the opening process, it is sufficient to confirm the business day, log in to the clerk (responsible person), and back up the data. After performing this opening process, the operation mode of the POS terminal 20 may be set to the full self mode, or may be set to another mode such as the normal mode. When setting to full self mode, the clerk may or may not log in. When the clerk does not log in, and then shifts to the normal mode, etc., or when the mode after the opening process is changed to the normal mode, etc., as described above, the same as when the clerk logs in from the full self mode. It is sufficient to perform the processing of. Further, in the normal mode or the double scan mode (full self mode), the clerk may be able to perform the registration process even when the clerk is not logged in.

Further, in the above example, the operation mode of the other POS terminal 20 is determined based on the operation mode switching information transmitted from the other POS terminal 20, but the operation mode of the other POS terminal 20 is determined in another embodiment. You may. For example, information about the operation mode itself may be transmitted, or the operation mode may be inquired to another POS terminal 20. Further, when determining the operation mode, for example, when the operation mode is other than the operation mode in which information such as registration information can be received in the predetermined operation mode in the other POS terminal 20. The operation mode may be determined when the reception is rejected by the POS terminal 20 of the above.

Further, in the above example, when the registration information cannot be transmitted to the second POS terminal 20-2 and the third POS terminal 20-3 (see FIG. 1), the cash register button (first cash register button BT21 and second cash register button BT22) Is grayed out, but other modes may be displayed. For example, the cashier button may be displayed with diagonal lines, or the cashier button may not be displayed. Further, in the above example, the second POS terminal 20-2 and the third POS terminal 20-3 are operated after the subtotal button BT10 (see FIG. 11) is operated, but the first register button BT21 is operated together with the subtotal button BT10. And when the second cash register button BT22 is displayed on one screen and the registration information is transmitted to another POS terminal (second POS terminal 20-2 or third POS terminal 20-3), instead of operating the subtotal button BT10, The first cash register button BT21 or the second cash register button BT22 may be operated. In this case, it is possible to reduce the time and effort required to operate the subtotal button BT10. Further, it is selected whether to display the subtotal button BT10, the first register button BT21 and the second register button BT22 on one screen, or to display the first register button BT21 and the second register button BT22 after operating the subtotal button BT10. It may be possible to set it.

Further, in the above example, the operation mode of the other POS terminal is displayed on the cash register button to notify the clerk, but it may be notified in another mode. For example, it may be displayed by an image other than a button that the store clerk cannot operate, may be notified by a mode other than the image, for example, by a voice emitted from a speaker, or may be notified by providing a lamp or the like.

Further, in the above example, in the cash register button, the operation mode display area, the status display area, the operation status display area, and the unsettled transaction number display area are stacked and displayed above and below the cash register number display area. It may be displayed in an embodiment. In addition, the status display area, the operating status display area, and the unsettled transaction number display area may not be displayed. Further, the cash register number, operation mode, status, operation state, number of unsettled transactions, etc. may be displayed in a mode other than characters, for example, a figure or a symbol.

Further, in the above example, in the other POS terminals 20 (second POS terminal 20-2 and third POS terminal 20-3), transferable information is generated according to the operation mode and the registration processing status, and the POS terminal (first POS terminal). Although it is transmitted to the terminal 20-1), it may be determined whether it can be taken over in another manner. For example, since the POS terminal 20 stores the operation mode of the other POS terminal 20, information on the registration processing status of the other POS terminal 20 can be obtained from the other POS terminal 20 (second POS terminal 20-2 and third POS terminal). It may be transmitted from 20-3) to determine whether or not the POS terminal (first POS terminal 20-1) can take over.

Further, in the above example, the operation mode of the other POS terminal 20 is stored by transmitting the operation mode switching information, and the operation mode of the other POS terminal 20 is determined based on the storage. It may be judged by the aspect. For example, when the operation mode is switched when a predetermined operation is performed, the stored operation mode may be rewritten or the operation mode may be determined by transmitting and receiving information regarding the predetermined operation.

Further, in the above example, the normal mode, the full self mode, the semi-self mode, and the double scan mode are provided as the operation modes, but some of them may not be provided. For example, the POS terminal 20 may have only a normal mode, a full self mode, and an accounting-only mode.

Further, in the above example, when switching the operation mode of another POS terminal 20, the operation mode of a specific POS terminal 20 is switched, but the operation mode of a plurality of specific POS terminals 20 is uniformly set. You may switch to. Regarding such an aspect, for example, two rows of two POS terminals 20 are arranged in a direction in which a customer who makes a purchase moves, and four POS terminals 20 arranged in two rows × 2 (hereinafter, hereinafter, An example will be described in which "upstream side 1st POS terminal", "upstream side 2nd POS terminal", "downstream side 1st POS terminal", and "downstream side 2nd POS terminal") are registered in advance as one group. When the mode and status of the other POS terminal 20 are determined in the upstream first POS terminal and the operation mode is switched from the normal mode to the semi-self mode (registration-only mode), the operation of the upstream second POS terminal is performed. The mode may also be switched to the semi-self mode (registration-only mode), and the operation modes of the downstream first POS terminal and the downstream second POS terminal may be collectively switched to the semi-self mode (accounting-only mode). By such a switching process, the operation mode of the POS terminal 20 of the entire group can be switched to the operation mode for efficient customer handling by switching the operation mode of one POS terminal 20. Therefore, the operation mode of the POS terminals 20 of the entire group can be switched to a suitable operation mode by a one-touch operation on one POS terminal 20.

Further, since the operation mode and status of the other POS terminal 20 are always displayed on the POS terminal 20, the switching button can be operated in consideration of the operation mode and the like of the other POS terminal 20. For example, in operating the upstream first POS terminal 20, it is assumed that the downstream first POS terminal 20 and the downstream second POS terminal are on standby, and the operation mode of the upstream second POS terminal is trading in the full self mode. At this time, when the above-mentioned batch switching is performed in the upstream side 1st POS terminal, the operation mode of the downstream side 1st POS terminal and the downstream side 2nd POS terminal is switched to the self mode (accounting only mode), and the upstream side 2nd POS terminal. For, the user may switch to the full self mode (registration-only mode) after the transaction is completed. When switching between these operation modes, it may or may not be notified by displaying on the customer side display unit 210 or the like that the operation mode is to be switched. By performing such batch switching, the operation of a plurality of POS terminals 20 constituting a group can be easily switched.

Further, in the above example, when the status of the other POS terminal 20 is normal, "normal" is displayed, but when the status is normal, the display is not performed, and when a status abnormality occurs, an abnormality occurs. The content of the effect or abnormality may be displayed. Further, when a plurality of status abnormalities occur, a part of them may be displayed or all of them may be displayed. Further, when displaying a part of the status abnormality, the status abnormality having a high recovery priority may be displayed. For example, when two status abnormalities, a receipt end and a change near end, occur, the change near end with a high recovery priority may be displayed. In addition, it may be possible to select whether to display a part or all of the status abnormalities.

Further, when a plurality of status abnormalities have occurred, the display of the status abnormalities may be switched each time the display area is pressed, that is, the display may be performed by a so-called toggle method. The toggle method display may be performed, for example, when displaying the operation mode. When performing the toggle display, for example, the mode may be set to return to the initial display (mode display, status display) according to the elapsed time after the pressing time.

Further, when the registration process and the settlement process are performed on different POS terminals 20, the payment means may be specified from the POS terminal 20 on which the registration process has been performed. For example, when a near-end occurs in the change machine 209 of the POS terminal 20 that performs the settlement process and a part of the payment processing function cannot be used, the payment method is credited or electronic money from the POS terminal 20 that has performed the registration process. It may be possible to specify to execute. In this case, when designating the payment means of the other POS terminal 20, for example, the operation of the key assigned to display the screen for designating the payment means of the other POS terminal 20 may be performed. .. Alternatively, a payment selection screen on which the payment type on the other POS terminal 20 can be selected by operating each button display may be displayed so that the button display on the payment selection screen cannot be operated (disabled). For example, each button of "cash", "credit", and "electronic money" as shown in FIG. 16A is displayed on the payment selection screen, and when a near end occurs in the change machine 209 and payment by cash cannot be performed, " You can hide the "cash" button or gray it out. The state in which a part of the payment processing function of the other POS terminal 20 cannot be used may be known based on the information transmitted from the other POS terminal 20.

Further, when the operation mode of the POS terminal 20 is the full self mode and the customer is registering the product, the information of the product registered on the other POS terminal 20 may be cleared. Before a customer who has registered a product on the POS terminal 20 operating in the full self mode interrupts the registration and is left as it is, or the registration of all products is completed. You may wish to make a payment at the POS terminal 20 operated by a clerk. In such a case, by clearing the product information registered in the other POS terminal 20 and returning to the initial screen, the next customer can use the POS terminal 20.

Further, in the above example, in the full self mode, the customer side display unit 205 continues to display the images GA01 and GA02 as shown in FIG. 15B even after the customer starts registering the product. However, after the product registration is started, the images GA01 and GA02 may be hidden (erased). Before starting product registration, it is effective to display the operation mode of the other POS terminal 20 in order to register and settle in the desired operation mode by checking the operation mode of the other POS terminal 20. However, it may be troublesome to move the POS terminal 20 after the registration is started. Therefore, by displaying the images GA01 and GA02 before starting the registration, it is possible to make it easier for the customer to select the registration and the settlement according to the desired operation mode. Further, since the images GA01 and GA02 are not displayed after the registration process is started, it is possible to easily avoid the complexity caused by the registration of the product on the plurality of POS terminals 20.

Further, in the full self mode, the screen displayed on the customer side display unit 205 is mirror-displayed on the store clerk side display unit 210, but in the mirror display, the images GA01 and GA02 are displayed on the store clerk side display unit 210. And the customer side display unit 205 may be different. For example, the images GA01 and GA02 may be displayed on one or both of the clerk side display unit 210 and the customer side display unit 205 before the product registration is started, and before the product registration is started. In addition, the images GA01 and GA02 may be displayed on one or both of the clerk side display unit 210 and the customer side display unit 205, and the combination thereof may be changed. In these cases, the customer can confirm the operation mode of the other POS terminal 20 and move by himself / herself, or the clerk can confirm the operation mode of the other POS terminal 20 and urge the customer to move. Further, the images GA01 and GA02 may be displayed when they are in a specific operation mode, for example, when they are in a mode other than the full self mode.
