FIGS. 8B and 8C are diagrams in the semi-self mode. 5 is a flowchart showing a basic flow of operation of the POS terminal 20.

  In the following description, as a different viewpoint from the above-described four operation mode classifications, the mode in which the POS terminal 20 executes the product registration process is the registration mode, and the mode in which the settlement process is executed is the accounting mode (or settlement). Mode).

(Normal mode)
As shown in FIG. 5A, the normal mode is an operation mode in which registration processing is executed on the store clerk side and settlement processing is executed on the customer side. 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 through the registration process to the settlement process.

  In the normal mode, the store clerk registers the customer's purchased products on the store clerk side (store clerk side scanner unit 212, store clerk side display unit 210, key operation unit 211). In other words, the POS terminal 20 executes a process for registering purchased products by the operation of the store clerk (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 store clerk is completed, the customer confirms the total amount of the purchased product on the store clerk side display unit 210, inserts money into the change machine 209, or operates the card settlement unit 208 to settle it (FIG. 5). (A) Lower row). That is, the POS terminal 20 executes the settlement process by the customer's operation or the like (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, first, on the clerk side, for example, the merchandise is scanned by the clerk-side scanner unit 212 (step S10: YES), and the merchandise is registered (step S11). After depressing a subtotal key (for example, a subtotal key displayed on the store clerk side display unit 210 or a subtotal key arranged on the key operation unit 211) (step S30: YES), on the customer side, for example, a change machine 209 Is settled (step S50), and the process is completed.

  The customer may be on standby until the registration process by the store clerk is completed (until the total amount is confirmed), but money may be put 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).

  Further, the store clerk may be on standby until the customer completes payment (until the customer takes a change or receipt), but may register a product purchased by the next customer. That is, the POS terminal 20 can register the purchased product of the next customer during the checkout process (the lower part of FIG. 5A). Further, the store clerk may be absent during the checkout by the customer (lower part of FIG. 5A). That is, during the customer's checkout, the customer's response may be finished.

  In addition, the POS terminal 20 controls the change / dispensing of the change / pick by the change machine 209 in order to prevent forgetting to change the change when there is change, and a sensor or the like indicates that the customer has removed the change / pipe. The receipt of the receipt by the printing unit 213 is controlled. 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. However, if there is a clerk, the above-described control is not necessarily performed. (In other words, the change and change of the bills and the receipt may be issued at the same time, or the receipt may be issued first). Further, according to the current operation mode and the presence / absence of a store clerk (for example, the presence / absence of a store clerk is recognized by a sensor), the timing of paying out change / fishing bills and issuing a receipt may be controlled.

(Full self mode)
As shown in FIG. 6A, the full self mode is an operation mode in which registration processing is executed on the customer side and settlement processing is executed on the customer side. That is, as shown in FIG. 6B, in the full self mode, the customer side is in the registration mode and the accounting mode. That is, the POS terminal 20 operates as a registration accounting mode when viewed through 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). In other words, the POS terminal 20 performs a purchase product registration process by a customer operation or the like (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 product on the customer side display unit 205, inserts money into the change machine 209, or operates the card settlement unit 208 to settle it (FIG. 6 (A ) Bottom). That is, the POS terminal 20 executes the settlement process by the customer's operation or the like (insertion of money into the change machine 209, operation of the card settlement unit 208) (lower part of FIG. 6A).

  That is, in the full self mode, as shown in FIG. 6 (B), on the customer side, for example, the customer side scan unit 206 scans the product (step S20: YES) and registers the product (step S21). After the registration completion key (for example, the registration completion key displayed on the customer side display unit 205) is pressed (step S40: YES), the customer side, for example, checks out by the change machine 209 (step S50), and processing Is completed.

  In the full self mode, as described above, the registration process and the settlement process are executed on the customer side, but the store clerk cannot do anything. That is, even when the POS terminal 20 is operating in the full self mode, the store clerk side scanner unit 212 can scan the store clerk code. Further, even when the POS terminal 20 is operating in the full self mode, it is possible to display various information (for example, a list described in FIG. 15) on the clerk-side display unit 210.

(Double scan mode)
As shown in FIG. 7A, the double scan mode is an operation mode in which registration processing is executed on both sides of 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 double scan mode, both the store 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 through the registration process to the settlement process.

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

  When the registration process is completed, the customer confirms the total price of the purchased product on the customer side display unit 205, inserts money into the change machine 209, or operates the card settlement unit 208 to settle it (FIG. 7 (A ) Bottom). That is, the POS terminal 20 executes the settlement process by the customer's operation or the like (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 clerk side and the customer side. For example, as shown in FIG. 7B, the merchandise side scanner unit 212 scans (step S10: YES), the product is registered (step S11), and the customer side scanner unit 206 scans (step S20: YES), the product is registered (step S21). Subtotal key (for example, a subtotal key displayed on the store clerk side display unit 210 or a subtotal key arranged on the key operation unit 211), or a registration completion key (for example, registration displayed on the customer side display unit 205) After the press of the completion key or the like (step S41: YES), payment is performed by the change machine 209, for example, on the customer side (step S50), and the process is completed.

  The store clerk may be on standby until payment by the customer is completed (until the customer receives a change or a receipt), but may register a product purchased by the next customer. That is, the POS terminal 20 can register the purchased product of the next customer during the checkout process (the lower part of FIG. 7A). Further, the store clerk may be absent during the checkout by the customer (the lower part of FIG. 7A). That is, during the customer's checkout, the customer's response may be finished.

(Semi-self mode)
The semi-self mode is an operation mode by two or more POS terminals 20, and as shown in FIG. 8A, a clerk of at least one POS terminal 20 (first POS terminal 20-1 in the example of FIG. 8). The registration process is executed on the customer 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 devices (one device of the first POS terminal 20-1 as shown in FIG. 8B in the example of FIG. 8) enters the registration-only mode, and one or more devices (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 case of 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, and the key operation unit 211) at the POS terminal 20 in the registration-only mode. In other words, the POS terminal 20 executes a process for registering purchased products by the operation of the store clerk (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 process by the clerk is completed, the customer moves to the POS terminal 20 in the accounting-only mode, confirms the total price of the purchased product on the clerk-side display unit 210, inserts money into the change machine 209, or pays by card. The unit 208 is operated and settled (lower part of FIG. 8A). That is, the POS terminal 20 executes the settlement process by the customer's operation or the like (insertion of money into the change machine 209, operation of the card settlement unit 208) (lower part of FIG. 8A).

  When the registration process is completed at the POS terminal 20 in the registration-only mode (first POS terminal 20-1 in the example of FIG. 8), the customer changes from the POS terminal 20 in the registration-only mode to the POS terminal 20 (in FIG. 8). In the example, the information is moved to the second POS terminal 20-2), but information necessary for the settlement process (registration information generated in the first POS terminal 20-1 in the registration-only mode) is stored in the destination POS terminal 20. 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 POS terminal 20 in the registration-only mode. Alternatively, the registration-only mode POS terminal 20 issues a medium (a medium on which a bar code or the like for obtaining information necessary for the checkout process is printed), and the accounting-only mode POS terminal 20 is read. The destination POS terminal 20 may be used.

  That is, in the semi-self mode, first, merchandise is 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 merchandise is registered (step S11) by scanning with the clerk-side scanner unit 212 (step S10: YES). After pressing a subtotal key (for example, a subtotal key displayed on the store clerk side display unit 210 or a subtotal key arranged on the key operation unit 211) (step S30: YES), for example, the POS terminal 20 in the accounting-only mode ( When one of the second POS terminal 20-2 and the third POS terminal 20-3) is designated (step S31: YES), registration information is transmitted to the designated POS terminal 20 (step S32), and the registration-only mode The processing at the POS terminal 20 is completed.

  Subsequently, as shown in FIG. 8C, after receiving the registration information (step S49: YES), the accounting-only mode POS terminal 20 (that is, the POS terminal 20 designated by the registration-only mode POS terminal 20). 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 the registration information is transmitted, the store clerk can register the purchased product of the next customer (the lower part of FIG. 8A). Further, the store 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 by, for example, a first registration button BT21 and a second registration button BT22 described in detail later. In addition, a screen on which images corresponding to each operation mode (for example, a button-like image) are arranged is displayed on the clerk-side display unit 210, and an image corresponding to the current operation mode is displayed on the screen. You may display in the display mode (For example, the display mode conspicuous rather than the display mode of another image) different from the image which does not respond | correspond. The operation mode may be displayed on the customer display unit 205 in the same manner.

  Further, the POS terminal 20 may notify information according to the current operation mode. For example, the customer display unit 205 may display a message corresponding to the current operation mode. Specifically, when the current operation mode is full self mode, for example, when waiting, the customer himself registers the product (message such as “I ask the customer to scan”) You may display on the customer side display part 205 (for example, scroll display with a big character).

(Operation mode transition)
Next, the transition (switching) of the operation mode of the POS terminal 20 will be described. The operation mode of the POS terminal 20 is changed according to an explicit mode change operation (an input on an operation mode setting screen, an operation of an operation mode setting button, etc.) by a store clerk. The operation mode is switched by switching means in the CPU 201. Specifically, the key operation unit 211 includes a plurality of buttons. According to the operation of the mode switching button 211a (see FIG. 3B) arranged at the uppermost and rightmost among these buttons. The operation mode shifts. Further, the operation mode of the POS terminal 20 is shifted according to an operation other than the explicit mode shift operation by the store clerk (for example, reading of the store clerk code). In addition, the POS terminal 20 has predetermined conditions (such as elapsed time and predetermined time (schedule)) that do not depend on store clerk operations, conditions related to transmission / reception of information such as commands with other terminals, etc. ) To shift the operation mode.

  In addition, since the mode switching button 211a is arranged at the corner of the key operation unit 211, it is possible to reduce an operation error when changing the mode and to easily change the operation mode. That is, when the mode switching button 211a is present at the corner of the key operation unit 211, for example, compared to the case where the mode switching button 211a is present near the center of the key operation unit 211, for example, the mode switching button 211a that is the operation target Since the number of adjacent buttons is small, it is unlikely that operation mistakes such as operating other buttons in a hurry will occur, and since the position of the mode switching button 211a that is the operation target can be instantly specified, mode transition operation without stress It can be performed.

  Further, since the mode switching button 211a is arranged at the upper right end (uppermost and rightmost) corner of the key operation unit 211, the mode shift operation is performed not only when the store clerk is at the store clerk side but also at the customer side. It becomes easy. In other words, the store clerk at the customer side usually cannot visually recognize each button of the key operation unit 211, but the mode switching button 211a present at the upper right end of the key operation unit 211 is extended from the customer side and searched. Since the mode switching button 211a as the operation target can be easily recognized only by (hand feeling), the store clerk at the customer side can perform the mode transition operation without moving to the store 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 store clerk operates from the customer side, so that the store clerk can easily operate. It becomes.

  In the present embodiment, the mode switching button 211a is arranged at the upper right corner of the key operation unit 211. However, if the position can be recognized only by groping (a position that can be recognized relatively easily), the mode is switched. The switching button 211a may be disposed at a position other than the upper right corner of the key operation unit 211, for example, at the lower right corner. Further, instead of or in addition to arranging the mode switching button 211a at a position that can be recognized only by groping (for example, at the upper right corner), it can be distinguished from other buttons even from the customer side. Alternatively, a mode switching button 211a may be formed. For example, the size of the mode switching button 211a may be different from the size of other buttons so that the mode switching button 211a 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 protrude more than the other buttons). ) The touch of the entire surface (the surface touched by the hand) of the mode switching button 211a may be different from the touch of the other buttons (for example, only the surface of the mode switching button 211a is rough or rough) You may make it feel, or you may make it provide a protrusion and a hollow only in 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 the various advantages as described above, but instead of arranging the mode switching button 211a in the key operation unit 211. Alternatively, 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 operation mode transition. FIG. 9A is a flowchart showing a flow of transition from the normal mode to the full self mode. FIG. 9B is a flowchart showing a flow of transition from the full self mode to the double scan mode. FIG. 10A is a flowchart showing a flow of transition from the normal mode to the semi-self mode (registration-only mode). FIG. 10B is a flowchart showing a 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 in FIG. 9A starts when the POS terminal 20 (normal mode) is not in use (that is, starts when neither the store clerk nor the customer uses it).

Step S100: Start counting the non-use time.
Step S101: It is determined whether use is started by a store clerk or a customer. If use has not 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 a non-use time has passed a predetermined time (for example, a preset 10 minutes). If 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 shifted from the normal mode to the full self mode.
Step S104: Ending the measurement of the non-use time. Then, the flowchart of FIG. 9A ends.

  In addition, when shifting to the full self mode, the store clerk may be notified of the transition to the full self mode (for example, sending information indicating that there is an undelivered product to the terminal carried by the store clerk). . Further, when the mode is shifted to the full self mode, a message for instructing or requesting the customer to perform self-registration may be displayed on the customer side display unit 205.

  FIG. 9A shows a flow relating to the 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 in FIG. 9A. It may be.

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

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 has been 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 shifted 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 (periodically at very short time intervals) in the POS terminal 20 (normal mode).

Step S120: It is determined whether or not there has been 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.

Step S121: It is determined whether 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, since at least one POS terminal 20 in the registration-only mode and one POS terminal 20 in the accounting-only mode are required, 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 another POS terminal 20 to be shifted to the semi-self mode (accounting only mode) has been designated. If so, 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 only mode) is transmitted to the other designated POS terminal 20.

Step S124: It is determined whether processing is in progress. If not, the process proceeds to step S125. If it is being processed, 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.

  The operation in step S120 is performed when there is no other POS terminal 20 that is already operating in the semi-self mode and there is no other POS terminal 20 that can be shifted in the semi-self mode. It is better not to be able to do it.

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

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

Step S131: It is determined whether processing is in progress. If not, the process proceeds to step S132. If it is in process, 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.

  FIG. 10B shows a flow relating to 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 illustrated. It may be the same as the flow of 10 (B).

  Further, the transition of the operation mode may be executed based on conditions 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 shifted 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 a first condition, it is determined whether the operation mode switching is permitted. When the operation mode switching is permitted, the operation mode is set. You may make it transfer. Further, based on the current operation mode (situation) of the POS terminal that has received the registration information, it may be determined whether or not the mode can be changed. 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, the operation mode is set when the operation mode switching information is received when the POS terminal 20 is on standby. 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 condition 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, 13 and 14 are display examples on the first POS terminal 20-1. FIG. 12 is an enlarged view of the first register button and the second 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 display contents of a registration screen in a scene where two items of merchandise (aspara) are registered.

  The subtotal button BT10 at the lower right of the screen is a button for instructing the end of product registration. The store clerk operates (touches) the subtotal button BT10 after the product registration is completed. The pause button BT11 is a button for pausing the own terminal (first POS terminal 20-1). The store clerk operates the pause button BT11 when leaving the terminal (for example, when searching for a product or not using the product for a while).

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

  As shown in FIG. 12, the first register button BT21 includes a first operation mode display area BT21A, a first status display area BT21B, a first operating state display area BT21C, a first register number display area BT21D, and a first unregistered button BT21. A 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, in this case, “full self” representing the full self mode is displayed. . In the first operation mode display area BT21A, for example, “normal” and “semi self” are displayed in addition to “full self”. When the “normal” character 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 “semi-self” character is displayed, the second POS terminal The operation mode 20-2 is the semi-self mode. In the normal mode, registration processing is performed on the store clerk side, and in the full self mode, registration processing is performed on the customer side. Further, in the semi-self mode, registration processing can be performed on the clerk side in the registration-only mode, and registration processing is not performed in the accounting-only mode. By displaying the operation mode on the first register button BT21, it is possible to tell the store clerk whether the registration process on the clerk side of the second POS terminal 20-2 and the registration process on the customer side are performed along with the operation mode in the second POS terminal 20-2. We are reporting. It should be noted that “registration only” and “accounting only” are displayed instead of the “semi-self” characters so that the user can clearly notify whether the mode is the registration-only mode or the accounting-only mode in the semi-self mode. Good.

  In the first status display area BT21B, the status of the second POS terminal 20-2, in this case, “too much change” is displayed, and it is displayed that the change machine 209 of the second POS terminal 20-2 is near full. In the first status display area BT21B, characters of “normal”, “lack of change” and “out of receipt” are displayed. When the characters “Normal” are displayed, no status abnormality has occurred in the second POS terminal 20-2. In addition, when the character “insufficient change” is displayed, the change of the change machine 209 is near-end, and when “receipt out” is displayed, the receipt sheet of the printing unit 213 is insufficient. The first status display area BT21B may display other information such as that the receipt paper is near-end.

  In the first operating state display area BT21C, the operating state of the second POS terminal 20-2, in this case “standby”, is displayed. In the second POS terminal 20-2, neither registration processing nor settlement processing is performed. It is indicated that the 2POS terminal 20-2 is in a standby state. In the first operating state display area BT21C, in addition to “standby”, characters such as “registering”, “settlement”, “offline”, and “call clerk (CALL)” are displayed. When the character “in registration” is displayed, the second POS terminal 20-2 is performing registration processing. When the “settlement” character is displayed, the change machine 209 cannot transmit / receive information to / from the second POS terminal 20-2 when “offline” is being processed. ing.

  In the first register number display area BT21D, the register number of the register to be displayed, here, the character of the second register (right) indicating the second POS terminal 20-2 is displayed. Since the second POS terminal 20-2 is arranged on the right side of the first POS terminal 20-1, "right" is displayed. In the first unsettled transaction number display area BT21E, the number of unsettled transactions in the registration information transmitted to the second POS terminal 20-2, “0” in this case, is displayed. By confirming the first unsettled transaction number display area BT21E, the store clerk determines the POS terminal to which the registration information is transmitted.

  Similarly, the second cash register button BT22 includes a second operation mode display area BT22A, a second status display area BT22B, a second operation state display area BT22C, a second cash register number display area BT22D, and a second unsettled transaction number display. A region BT22E is provided. These displays are almost common to the first register button BT21. Note that the POS terminal 20 transmits information on the status of the terminal, the operating state, and the number of unsettled transactions to other POS terminals 20 in the POS system 1.

  The first cash register button BT21 is a button for transmitting registration information obtained by registering a product at the first POS terminal 20-1 to the second cash register (the second POS terminal 20-2 in FIG. 1). The BT 22 is a button for transmitting registration information obtained by registering a product in the first POS terminal 20-1 to the third register (the third POS terminal 20-3 in FIG. 1). In other words, the first register button BT21 and the second register button BT22 are buttons for selecting (designating) a POS terminal that transmits registration information.

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

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

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

  FIG. 13 is a display example on the small plan 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 small plan surface in the scene following the scene of FIG. 11 (the scene after the operation of the subtotal button BT10).

  In FIG. 13, a current total button BT20, a first register button BT21, a second register button BT22, and a checkout button BT25 are provided at the lower right portion of the screen. The current total button BT20 is a button for instructing input of a deposit amount. When the store clerk executes the checkout process at the terminal (first POS terminal 20-1), after receiving a deposit greater than the total amount from the customer (after entering a deposit amount greater than the total amount), The button BT20 is operated.

  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 (the second POS terminal 20-2 or the third POS terminal 20-3). By depressing the first cash register button BT21 or the second cash register button BT22, the settlement process can be performed at the second POS terminal 20-2 or the third POS terminal 20-3. Note that after the subtotal button 10 is operated, the first cash register button BT21 and the second cash register button BT22 may not be displayed on the assumption that the settlement process is performed at 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 is displayed without displaying the first register button BT21 and the second register button BT22 in the stage before operating the subtotal button BT10. The first registration button BT21 and the second registration button BT22 may be displayed after operating the BT10.

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

  Information necessary for executing the checkout process is encoded and printed on the bill. For example, the registration information itself used for the checkout process may be printed as a QR code (registered trademark) on the check ticket, or information for specifying the registration information used for the checkout process (for example, transaction Identification information or the like) may be printed as a barcode. When the registration information itself used for the checkout 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 bill is Payment can be made at the POS terminal 20 in a lane other than the included lanes. Therefore, even if a failure such as offline occurs in the lane including the POS terminal 20 that issued the bill, the checkout process can be performed. Further, when the POS terminal 20 includes the lane including the POS terminal 20 offline, transmission / reception is disabled, or communication is disabled, the checkout button BT32 displayed by operating the subtotal button BT10 shown in FIG. May be displayed in a pop-up or in a different manner. Specifically, the color may be changed, blinked, or grayed down as compared to the normal checkout button BT32.

  In the aspect of issuing the bill printed with the QR code, the POS terminal 20 (second POS terminal 20-2 or third POS terminal 20-3) that has read the bill (QR code) is, for example, The settlement process is executed using the registration information obtained from the QR code. Moreover, in the aspect which issues the bill which printed the said barcode, the POS terminal 20 (2nd POS terminal 20-2 or 3rd POS terminal 20-3) which read the said bill (barcode) is, for example, A registration information acquisition request including information (transaction identification information, etc.) for specifying registration information obtained from the bar code is sent to the terminal (first POS terminal 20-1, second POS terminal 20- 2 or the third POS terminal 20-3) or a terminal that has acquired registration information from the terminal that issued the bill. For example, the registration information is received from the terminal that has transmitted the registration information acquisition request, and the settlement process is executed. In other words, in the aspect of issuing the bill printed with the barcode, the terminal (first POS terminal 20-1, second POS terminal 20-2 or third POS terminal 20-3) that issued the bill The terminal (store controller 30 or the like) that has acquired the registration information from the terminal that issued the bill is from the POS terminal 20 (second POS terminal 20-2 or third 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 registration information acquisition request transmission source (registration information request source).

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

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

  As described above, the current total button BT20 is a button that is operated after inputting a deposit amount greater than or equal to the total amount. FIG. 13 illustrates a situation where a deposit amount greater than or equal to the total amount is entered. Absent. Therefore, in FIG. 13, as with the second register button BT22, the current total button BT20 may be displayed in a display mode indicating that the operation is not valid.

  FIG. 14 is a display example on the payment screen displayed on the salesclerk 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 the numerical value of the deposit amount “¥ 503” has been entered. The scene before the operation of the current button BT20). ing. The scene of FIG. 14 is a scene after the input of a deposit amount “¥ 503” equal to or greater than the total amount “¥ 383”, that is, a case where the settlement process is executed in the own terminal (first POS terminal 20-1). Therefore, buttons (first cash register button BT21, second cash register button BT22, check ticket button) for causing the POS terminal 20 (second POS terminal 20-2 or third POS terminal 20-3), which is another terminal, to execute the settlement process. BT25) is displayed in a display form that the operation is not valid.

  In the scene of FIG. 11, when the current total button BT 20 is operated, the change “¥ 120” is discharged from the change machine 109 and a receipt or the like is issued by the printing unit 113.

  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 store clerk is performing the product registration process is displayed. The customer can input money from the change machine 209 during the registration process of the product. When the settlement process is started, a screen corresponding to the settlement process is displayed.

(Display in full self mode)
Next, the display on 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 on the POS terminal 20 in the full self mode.

  FIG. 15A is a display example of a registration start screen displayed on the customer side display unit 205 of the POS terminal 20 in the full self mode. In FIG. 15A, a registration start button BT30 on the right side of the screen is a button for instructing 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, a registration start screen in English is displayed. Thus, a button for switching to Japanese, Chinese, or Korean will be displayed. The image GA01 below the button BT37 shows the state of the No. 2 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 No. 3 register (the 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 on the customer side display unit 205 shifts from the registration start screen to the registration screen.

  FIG. 15B is a display example of a registration screen displayed on the customer side display unit 205 of the POS terminal 20 in the full self mode. In the example shown in the figure, on the right side of the registration screen, the registered product name, unit price, the number of registered products (the number of purchases), and the total amount are displayed as registration contents. Here, the registration content of a scene where two items of merchandise (pears and apples) are registered is displayed. In addition, immediately after the registration start button BT30 is operated on the registration start screen shown in FIG. 15A and the registration screen is displayed, a registration screen in which no product has been registered yet (initial state registration screen). For convenience of explanation, FIG. 15B shows an example of a registration screen after a product has already been registered. Buttons BT35 to 37 and images GA01 and GA02 are also displayed on the screen after the product is registered.

  The accounting button BT32 at the lower right of the screen is a button for instructing the end of product registration. When the customer operates the checkout button BT32 after completing the product registration, the POS terminal 20 shifts to the checkout mode and executes the checkout process. The salesclerk call button BT33 is a button for calling a salesclerk. The customer operates the store clerk call button BT33 when calling the store clerk (for example, when the store clerk needs support). When the customer operates the store clerk call button BT33, for example, a notification is given to the mobile terminal possessed by the store clerk, and sound is output from the mobile terminal or the mobile terminal vibrates. Further, when the customer operates the store clerk call button BT33, a predetermined lamp (indicator lamp such as a sign pole) installed in the store may be turned on.

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

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

  FIG. 16 is a display example of a payment screen displayed on the customer side display unit 205 of the POS terminal 20 in the full self mode. FIG. 16A shows 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 checkout button BT32 is operated on the registration screen (see FIG. 15B). The payment method selection screen shown in the drawing displays the total amount of payment (here, 240 yen), payment method options, and the like. As payment method options, cash, credit, electronic money, and the like are displayed as selectable operation buttons.

  FIG. 16B is a settlement screen (payment screen) displayed when payment by cash is started. For example, the POS terminal 20 displays a deposit screen as shown in FIG. 16B when cash is selected on the payment method selection screen (see FIG. 16A). On the payment screen shown in the figure, an image showing where to put money is displayed on the left side of the screen, and the payment amount (240 yen in this case), the amount of money (deposited amount), etc. are displayed on the right side of the screen. Is done. FIG. 16C is a settlement screen (payment determination screen) displayed when the deposit amount is determined. 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. In the payment determination screen shown in the figure, the payment amount (240 yen in this case), the amount of money (deposited amount, 250 yen here), fishing (10 yen here), etc. are displayed on the right side of the screen. On the left side of the screen, a guide for determining the amount to be deposited (here, “If you like, 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 payment screen (change screen) displayed when changing is discharged. For example, the POS terminal 20 displays a change screen as shown in FIG. 16D when the end (receipt) button BT40 is operated on the payment determination screen (FIG. 16C). In the change screen shown in the figure, an image prompting receipt of change is displayed on the left side of the screen, and the payment amount (240 yen in this case) and the input amount (deposit amount. 250 here) are continued on the right side of the screen. Yen), fishing (here, 10 yen), 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. 16E when the change is removed from the outlet of the change machine 209. Note that the POS terminal 20 may determine that the change has been removed when a sensor such as a photosensor is installed in the vicinity of the outlet, and the sensor recognizes an object (assuming a customer's hand).

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

  The POS terminal 20 displays a registration start screen (FIG. 15A) after displaying the receipt screen (FIG. 16E). For example, the POS terminal 20 displays a registration start screen after the receipt is removed from the issue port of the printing unit 213. The POS terminal 20 may include a sensor that can recognize that the receipt has been removed from the issuing port.

  If the change amount is equal to the deposit amount and no change is generated, the change screen (FIG. 16D) is not displayed and the receipt screen (FIG. 16C) is displayed from the payment screen (FIG. 16C). )).

  As described above, in the full self mode, when a customer registers and settles a 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 situation of the operation. Then, a payment screen is displayed on the customer display unit 205. The POS terminal 20 also displays the same display content as the display content displayed on the customer display unit 205 on the store clerk display unit 210. For example, the POS terminal 20 displays the same screen as that on the customer display unit 205 on the store clerk display unit 210 (so-called mirror display or mirroring display). Note that displaying similar display contents is not limited to displaying exactly the same screen, and includes that some display contents and layouts are different. For example, if it is a registration screen, contents essential for the registration operation (for example, the name of the registered product, the unit price, the number of registered products (the number of purchases) in FIG. 15B, the total price, “vegetable” ”Button BT38, checkout button BT32, etc.) may be included in displaying the same display contents even if at least some of the other display contents are different. .

  On the clerk side display unit 210 of the first POS terminal 20-1 in the full self mode, a mirror image of the image displayed on the customer side display unit 205 is displayed, and an image similar to 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 in the clerk side display unit 210.

(Display in semi-self mode)
The semi-self mode includes 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. In addition, a predetermined standby screen is displayed on the customer display unit 205 until registration information is transmitted from another POS terminal 20, and after the registration information is transmitted, a settlement process in the full self mode is performed. An image similar to the image at the time 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 registration of the product is started, and after the registration of the product is started, the settlement process from the registration process in the clerk side display unit 210 in the normal mode is performed. An image similar to the image at the time of execution is displayed. In the semi-self mode, since the settlement is not performed by the own device, the current total key (see FIG. 13) may not be displayed.

(Determination and display of operation modes of other POS terminals)
3 is a flowchart showing an example of the operation of the POS system 1. Specifically, the flowchart of FIG. 17 is a flowchart for determining the display mode of the first register button and the second 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 the takeover possible information is received. As will be described later, when the second POS terminal 20-2 and the third POS terminal 20-3 are ready to receive the registration information, the second POS terminal 20-2 and the third POS terminal 20-3 transmit the transferable information to the first POS terminal 20-1. The first POS terminal 20-1 determines whether or not the takeover enable information is received.
Step S212: It is determined whether the second register (second POS terminal 20-2) can be taken over. Here, it is determined whether the second POS terminal 20-2 can be taken over based on whether the takeover-possible information is received from the second POS terminal 20-2. When the second POS terminal 20-2 can take over, the process proceeds to step S213. When the second POS terminal 20-2 cannot take over, the process proceeds to step S214.
Step S213: The first POS terminal 20-1 displays the first register button BT21 in an active manner. By actively displaying the first 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 register button BT21 in gray-down. By displaying the first registration button BT21 in gray-down, it is possible to notify the second POS terminal 20-2 that transmission for taking over the registration information cannot be performed.

Step S215: It is determined whether the third register (third POS terminal 20-3) can be taken over. Here, it is determined whether the third POS terminal 20-3 can be taken over based on whether the takeover-possible information is received from the third POS terminal 20-3. When the third POS terminal 20-3 can take over, the process proceeds to step S216. When the third POS terminal 20-3 cannot take over, the process proceeds to step S217.
Step S216: The first POS terminal 20-1 displays the second register button BT22 in an active manner. By actively displaying the second 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 register button BT22 in gray-down. By displaying the second registration button BT22 in gray-down, it is possible to notify the third POS terminal 20-3 that transmission for taking over 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). If 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. If the current mode is not the normal mode or the semi-self mode (registration-only mode), the second POS terminal 20-2 proceeds to Step SS223.
Step S222: The second POS terminal 20-2 determines whether the store clerk is performing the product registration process. The second POS terminal 20-2 ends the flowchart of FIG. 17 when the store clerk is performing the product registration process. The second POS terminal 20-2 proceeds to step S223 when the store 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. If the current mode is the full self mode, the second POS terminal 20-2 proceeds to step S224. If the current mode is not the full self mode, the second POS terminal 20-2 proceeds to step S225.
Step S224: The second POS terminal 20-2 determines whether the customer is performing a 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 store clerk has not performed the product registration process.
Step S225: The second POS terminal 20-2 transmits takeover enable information to the first POS terminal 20-1. The second POS terminal 20-2 informs 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. Note that 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). If 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. If the current mode is not the normal mode or the semi-self mode (registration-only mode), the third POS terminal 20-3 proceeds to step S233.
Step S232: The third POS terminal 20-3 determines whether the store clerk is performing a product registration process. The third POS terminal 20-3 ends the flowchart of FIG. 17 when the store clerk is performing the product registration process. The third POS terminal 20-3 proceeds to step S233 when the store 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. If the current mode is the full self mode, the third POS terminal 20-3 proceeds to step S234. If the current mode is not the full self mode, the third POS terminal 20-3 proceeds to step S235.
Step S234: The third POS terminal 20-3 determines whether the customer is performing a 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 store clerk has not performed the product registration process.
Step S235: The third POS terminal 20-3 transmits the takeover enable 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. Note that 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.

  Thus, according to the present embodiment, in the POS terminal 20 (for example, the first POS terminal 20-1), the other POS terminals 20 (for example, the second POS terminal 20-2 and the third POS terminal 20-3) in the POS system 1 are used. The operation mode is displayed. For this reason, since the operation mode of the other POS terminals 20 in the POS system 1 can be grasped, the store clerk can distribute customers to the POS terminals 20 that can be operated. Therefore, a plurality of POS terminals can be operated efficiently.

  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 registering the product from another POS terminal 20 (for example, the first POS terminal 20-1) and settles it. It can be processed. For this reason, since the situation where a customer stays in one POS terminal 20 can be suppressed, the settlement process can be performed smoothly.

  Further, the POS terminal 20 (for example, the first POS terminal 20-1) may prohibit transfer of registration information to another POS terminal 20 (for example, the second POS terminal 20-2 or the third POS terminal 20-3). For this reason, it is possible to prevent the registration process in the other POS terminals 20 from being hindered, so that the registration process can be performed smoothly. Specifically, when another 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 store clerk is performing the product registration process. Or, in the full self mode, when the customer is registering a product, the transfer of registration information is prohibited. For this reason, since the registration process is not performed in the POS terminal 20 that takes over the registration information, the settlement can be started quickly, the confusion of the place where the settlement is performed can be prevented, and the settlement process can be performed smoothly. Can do.

  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 register button BT21 and the second register button BT22 are buttons for transmission, the store clerk selects 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. Transmission processing can be performed while watching. Therefore, the registration information can be easily taken over.

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

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

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

  Further, in the above example, the POS terminal 20 includes one printing unit 213 that can freely change the direction (direction of the medium issue port) from the store clerk side to the customer side and from the customer side to the store clerk side. You may make it provide the two printing parts which have a medium issuing port in the side. In other words, the POS terminal 20 has a clerk side printing unit having a medium issuing port on the clerk side and a medium issuing port on the customer side instead of the single printing unit 213 that can change the direction of the medium issuing port in a rotatable manner. 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 (store clerk, customer) holds in his hand and recognizes the identification information close to the object (product, etc.). It may be of a type. For example, it may be a fixed type that recognizes the object closer. The same applies to the clerk side scanner unit 212.

  In the above example, when switching the operation mode, the POS terminal 20 may display that the operation mode is switched on at least one of the customer-side display unit 205 or the clerk-side display unit 210. . For example, when switching from full self mode to semi-self mode (accounting only mode), at the time of switching (or before switching), for a predetermined time (for example, about several seconds), the customer side display unit 205 will “switch to accounting only mode”, etc. A message may be displayed. Note that after the operation mode is switched, a message indicating that the operation mode has been switched may be displayed.

  In the full self mode in which the clerk is not logged in, the POS terminal 20 maintains the full self mode, switches to the normal mode, or switches to the double scan mode when the clerk logs in. You may determine according to operation (for example, button operation) of a salesclerk.

  In other words, the POS terminal 20 has 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 in the full self mode when the clerk is not logged in. A button for switching may be displayed, and the operation mode after login may be controlled depending on which button is operated. In addition, for example, if you are asked to support the store clerk to leave everything to the store clerk (when the store clerk is called), the store clerk operates the button to switch to the normal mode after logging in and register the product. After that, if the customer asks for support to leave a part to the store clerk (to register the customer himself but want the store clerk to cooperate) (when the store clerk is called), the store clerk double-scans after logging in. If you log in for some reason (for example, check processing status) by operating the button to switch to the mode, but the customer wants to register himself or does not require the support of the store clerk (or temporarily If the customer is not logged in and cannot support the customer), the store clerk operates the button to maintain the full self mode after logging in. When the full self mode is maintained after the clerk logs in, the product name of the product registered by the customer may not be displayed on the clerk side display unit 210 from the viewpoint of privacy and the like. However, information that does not affect privacy or the like (cumulative amount during registration, etc.) may be displayed. If the accumulated amount during registration is displayed, for example, the store clerk can appropriately confirm the right of lottery (whether or not the purchase amount has exceeded a predetermined amount, etc.), so that the lottery can be prepared in advance.

  Further, when the POS terminal 20 is turned on, an opening process may be performed. In the opening process, confirmation of business days, login of a store clerk (responsible person), and backup of data may be performed. 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 the full self mode, the clerk may or may not log in. If the clerk does not log in and then shifts to the normal mode, etc., or if 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 process. Further, in the normal mode or the double scan mode (full self mode), even when the store clerk is not logged in, registration processing may be performed on the store clerk side.

  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 manner. May be. For example, information regarding the operation mode itself may be transmitted, or the other POS terminal 20 may be inquired about the operation mode. Further, when determining the operation mode, for example, when the other POS terminal 20 is in an operation mode other than the operation mode in which information such as registration information can be received in the predetermined operation mode, the other The operation mode may be determined when reception is rejected at the POS terminal 20.

  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 registration buttons (first registration button BT21 and second registration button BT22). The display is grayed out, but may be displayed in another manner. For example, the register button may be displayed with a diagonal line, or the register button may not be displayed. In the above example, the second POS terminal 20-2 and the third POS terminal 20-3 are operated after operating the subtotal button BT10 (see FIG. 11). However, the first register button BT21 is operated together with the subtotal button BT10. And when the second 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 registration button BT21 or the second registration button BT22 may be operated. In this case, it is possible to reduce time and effort for operating the subtotal button BT10. Select 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.

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

  In the above example, in the cash register button, the operation mode display area, the status display area, the operating state display area, and the unsettled transaction count display area are stacked and displayed above and below the cash register number display area. You may display in an aspect. Moreover, it is good also as an aspect which does not display about a status display area, an operation state display area, and an unsettled transaction number display area. Further, the cash register number, operation mode, status, operating state, number of unsettled transactions, etc. may be displayed in a form other than characters, for example, a figure or a symbol.

  In the above example, the other POS terminals 20 (the second POS terminal 20-2 and the third POS terminal 20-3) generate transferable information according to the operation mode and the registration processing status and generate the POS terminal (first POS terminal). Although it transmits to the terminal 20-1), you may determine whether it can take over in another aspect. 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 is transmitted to the other POS terminals 20 (second POS terminal 20-2 and third POS terminal). 20-3), and it may be determined whether or not the POS terminal (first POS terminal 20-1) can take over.

  In the above example, the operation mode switching information is transmitted to store the operation mode of the other POS terminal 20, and the operation mode of the other POS terminal 20 is determined based on the storage. You may determine by 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 on the predetermined operation.

  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 mode. However, a part of the normal mode, the full self mode, and the double scan mode may be provided. For example, the POS terminal 20 having only the normal mode, the full self mode, and the accounting-only mode may be used.

  In the above example, when the operation mode of the other POS terminal 20 is switched, the operation mode of the specific POS terminal 20 is switched. However, the operation mode of the specific plurality of POS terminals 20 is uniformly set. You may make it switch to. With regard to such an aspect, for example, two rows of two POS terminals 20 are arranged in the direction in which a shopping customer moves, and four POS terminals 20 (hereinafter referred to as “two rows × two”) are arranged. An example will be described in which “upstream first POS terminal”, “upstream second POS terminal”, “downstream first POS terminal”, and “downstream second POS terminal”) are registered in advance as one group. When the operation mode is switched from the normal mode to the semi-self mode (registration-only mode) in the upstream first POS terminal after determining the mode and status of the other POS terminals 20, 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 batch switching may be performed to switch the operation mode of both the downstream first POS terminal and the downstream second POS terminal to the semi-self mode (accounting-only mode). By such switching processing, the operation mode of the POS terminals 20 of the entire group can be switched to the operation mode in which efficient customer purchase is performed 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.

  In addition, since the operation mode and status of the other POS terminals 20 are always displayed on the POS terminal 20, the switching button can be operated in consideration of the operation mode of the other POS terminals 20. For example, when operating the upstream first POS terminal 20, the downstream first POS terminal 20 and the downstream second POS terminal are on standby, and the upstream second POS terminal is operating in the full self mode. At this time, when the above-mentioned batch switching is performed in the upstream first POS terminal, the operation mode of the downstream first POS terminal and the downstream second POS terminal is switched to the self mode (accounting only mode), and the upstream second POS terminal May be switched to the full self mode (registration-only mode) after the transaction ends. When switching between these operation modes, notification that the operation mode is to be switched may be displayed on the customer display unit 210 or the like, or may not be notified. By performing such collective switching, the operation of the plurality of POS terminals 20 constituting the group can be easily switched.

  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 an abnormality occurs when a status abnormality occurs. You may make it display the effect and the content of abnormality. Further, when a plurality of status anomalies have occurred, some of them may be displayed, or all of them may be displayed. Moreover, when displaying a part of status abnormality, you may make it display a status abnormality with a high recovery priority. For example, when two status anomalies have occurred, a receipt end and a change near end, a change near end with a high recovery priority may be displayed. Further, it may be possible to select whether to display some or all of the status anomalies.

  Further, when a plurality of status anomalies have occurred, display may be performed by a so-called toggle method in which the status anomaly display is switched each time the display area is pressed. You may perform the display by a toggle system, for example, when displaying an operation mode. When performing toggle display, it is good also as an aspect which returns to initial display (mode display, status display) according to the elapsed time after pressing time, for example.

  Further, when the registration process and the settlement process are performed by different POS terminals 20, the settlement means may be designated from the POS terminal 20 that has performed the registration process. For example, when a near end or the like occurs in the change machine 209 of the POS terminal 20 that performs the settlement process, and a part of the settlement processing function cannot be used, the settlement means 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 settlement means of another POS terminal 20, for example, an operation of a key assigned to display a screen for designating the settlement means of another POS terminal 20 may be performed. . Alternatively, it is possible to display a payment selection screen in which the payment type in the other POS terminal 20 can be selected by each button display operation, and to disable (invalidate) the button display on this payment selection screen. For example, each button of “cash”, “credit”, and “electronic money” as shown in FIG. 16A is displayed on the payment selection screen. When a near end occurs in the change machine 209 and payment cannot be made with cash, The “cash” button may not be displayed or may be grayed out. The state in which a part of the payment processing function in the other POS terminal 20 cannot be used may be known based on 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 on the product registered at the other POS terminal 20 may be cleared. Before a customer who has registered a product at the POS terminal 20 operating in the full self mode interrupts the registration on the way and is left as it is, or before the registration of all the products is completed. In some cases, the store clerk may wish to make a payment at the POS terminal 20 operated. In such a case, the next customer can use the POS terminal 20 by clearing the product information registered at the other POS terminal 20 and returning to the initial screen.

  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 registration of the product is started, the images GA01 and GA02 may not be displayed (erased). Before starting the registration of the product, it is effective to display the operation mode of the other POS terminal 20 in order to perform registration and settlement in the desired operation mode by confirming the operation mode of the other POS terminal 20. However, the movement of the POS terminal 20 may be troublesome after registration is started. For this reason, by displaying the images GA01 and GA02 before starting the registration, it is possible to make it easy for the customer to select the registration and settlement according to the preferred operation mode. In addition, after the registration process is started, the images GA01 and GA02 are not displayed, so that it is possible to easily avoid the complexity caused by the product registration performed by the plurality of POS terminals 20.

  In the full self mode, the screen displayed on the customer-side display unit 205 is mirror-displayed on the clerk-side display unit 210. In the mirror display, the images GA01 and GA02 are displayed on the clerk-side display unit 210. And the customer display unit 205 may be different. For example, before the registration of the product is started, 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 before the registration of the product 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, or a 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 prompt the customer to move. The images GA01 and GA02 may be displayed when a specific operation mode is set, for example, when a mode other than the full self mode is set.
