[Overview of each operation mode]
Next, the operation mode of the POS terminal 20 will be described. The POS terminal 20 has a plurality of operation modes. Specifically, the POS terminal 20 has four types of operation modes (normal mode, full self mode, double scan mode, and semi self mode). The operation modes described below are the operation modes related to accounting during normal business (operation modes related to product registration processing and checkout processing). This does not include a maintenance mode when a worker or the like performs setting work or maintenance work, a training mode when a new employee performs training, or the like.
In the present embodiment, “accounting” is a concept including, for example, from product registration to settlement (settlement) for a registered product in one transaction.

  5 to 8 are diagrams for explaining the outline of the operation mode of the POS terminal. FIG. 5 is a diagram for explaining the outline of the normal mode. FIG. 5A is a schematic diagram showing the flow of processing (product registration processing, checkout processing) in normal mode and the operation of a person (store clerk, customer).

It is the flowchart which showed the basic flow of operation | movement. FIG. 7 is a diagram for explaining the outline of the double scan mode. FIG. 7A is a schematic diagram showing the flow of processing (product registration processing, checkout processing) and the operation of a person (customer) in the double scan mode, and FIG. 7B is a diagram of the POS terminal 20 in the double scan mode. It is the flowchart which showed the basic flow of operation | movement. FIG. 8 is a diagram for explaining the outline of the semi-self mode. FIG. 8A is a schematic diagram showing the flow of processing (product registration processing and checkout processing) in semi-self mode and the operation of a person (customer). FIGS. 8B and 8C are diagrams in semi-self mode. 5 is a flowchart showing a basic flow of operation of the POS terminal 20.

  In the following description, when the POS terminal 20 is called a registration mode, a mode in which the product registration process is executed is referred to as a registration mode, and a mode in which the payment process is executed is referred to as a checkout mode, as a starting point different from the classification of the four operation modes described above. There is.

[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 checkout mode. That is, the POS terminal 20 operates as a registration / settlement mode when viewed throughout 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 bill and the issue of the receipt may be performed simultaneously, 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 settlement mode. That is, the POS terminal 20 operates as a registration / settlement 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). 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.
For example, during the operation in the full self mode, the clerk side display unit 210 has a screen similar to that displayed on the customer side display unit 205 in accordance with the registration process and the settlement process performed on the customer side. May be displayed. In other words, the clerk side display unit 210 may display the content displayed on the customer side display unit 205 so as to be mirrored. Thereby, the store clerk can grasp what kind of operation the customer is performing in the full self mode and what kind of processing state the POS terminal 20 is in.

[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 checkout mode. That is, the POS terminal 20 operates as a registration / settlement mode when viewed throughout 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.

  Note that the store clerk may be on standby until payment by the customer is completed (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. 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, the salesperson side of at least one POS terminal 20 (POS terminal 20-1 in the example of FIG. 8). The registration process is executed at, and the settlement process is executed at the customer side of the other POS terminal 20 (one of the POS terminal 20-2 and POS terminal 20-3 in the example of FIG. 8). Mode. That is, in the semi-self mode, one or more devices (one device of the POS terminal 20-1 as shown in FIG. 8B in the example of FIG. 8) enters the registration-only mode, and one or more other devices (FIG. 8). In the example, as shown in FIG. 8 (C), the POS terminals 20-2 and 20-2) are in the adjustment 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 store clerk is completed, the customer moves to the POS terminal 20 in the payment only mode, confirms the total price of the purchased product on the store clerk side display unit 210, inserts money into the change machine 209, or makes a card settlement. 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 in the POS terminal 20 in the registration-only mode (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 the settlement-only mode (example in FIG. 8). The POS terminal 20-2) is moved to the destination POS terminal 20, but information necessary for the settlement process (registration information generated in the POS terminal 20 in the registration-only mode) is supplied.

  The destination POS terminal 20 (a POS terminal 20 that executes the settlement process among the POS terminals 20 in the settlement-only mode) may be specified in the POS terminal 20 in the registration-only mode. Alternatively, the POS terminal 20 in the registration-only mode issues a medium (a medium on which a bar code or the like for acquiring information necessary for the adjustment process is printed) and reads the medium, and the POS terminal 20 in the adjustment-only mode 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 (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 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), for example, the POS terminal 20 in the adjustment only mode ( When one of the POS terminals 20-2 of the POS terminal 20-2) is designated (step S31: YES), the registration information is transmitted to the designated POS terminal 20 (step S32), and the POS in the registration-only mode is performed. Processing at the terminal 20 is completed.

  Subsequently, as shown in FIG. 8C, after receiving the registration information (step S49: YES), the POS terminal 20 in the adjustment 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 in the POS terminal 20 in the settlement-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).

[Operation mode notification]
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. 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).

[Transition of operation mode]
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, or the like) by a store clerk. 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.

  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 (settlement 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 check-out mode are necessary, for example, when the POS terminal 20 is the POS terminal 20-1. Then, it is determined whether one of the POS terminals 20-2 and 20-3 operates in the semi-self mode (registration-only mode) and the other operates in the semi-self mode (settlement-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 (settlement 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 (settlement 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 (mode for payment only)]
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 (settlement-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 (settlement only mode). Then, the flowchart of FIG. 10B ends.

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

[Display on the clerk side and customer side in double scan mode]
The double scan mode is a mode in which registration processing is executed on both the clerk side and the customer side. Hereinafter, display of the clerk side display unit 210 and the customer side display unit 205 during the registration process will be described.

  FIG. 11 is a flowchart illustrating an example of an operation when registering a product. The flowchart in FIG. 11 starts at all times (periodically at very short time intervals) in the POS terminal 20 (double scan mode). The dashed rectangle P will be described later.

  Step S400: It is determined whether or not the product has been scanned by the scan of the clerk side scanner unit 212 or the like. That is, it is determined whether or not the clerk has scanned by the clerk side scanner unit 212, touched the clerk side display unit 210, or pressed the key operation unit 211 or the like. If the product has been scanned, the process proceeds to step S401. If the product has not been scanned, the process proceeds to step S410.

Step S401: Register a product. In the registration, information indicating that the clerk has registered is also registered (stored). Specifically, the registration classification “1 (store clerk side)” is stored.
Step S402: The product is displayed on the clerk side display unit 210 in a normal display mode.
Step S403: The product is displayed on the customer-side display unit 205 in a display mode that is more emphasized than the normal display mode.

  Step S410: It is determined whether or not the product has been scanned by the customer-side scanner unit 206. That is, it is determined whether or not the customer has scanned by the customer side scanner unit 206 or touched the customer side display unit 205. If the product has been scanned, the process proceeds to step S411. If the product has not been scanned, the process returns to step S400.

Step S411: A product is registered. In the registration, information indicating that the customer has registered is also registered (stored). Specifically, the registration category “2 (customer side)” is stored.
Step S412: The product is displayed on the clerk-side display unit 210 in a display mode that is more emphasized than the normal display mode.
Step S413: The product is displayed on the customer side display unit 205 in a normal display mode.

  Step S420: It is determined whether or not registration of all products to be purchased has been completed. That is, it is determined whether either the subtotal key displayed on the store clerk display unit 210 or the registration completion key displayed on the customer display unit 205 has been pressed. If registration of all products is completed, the process proceeds to step S421. If not completed, the process returns to step S400.

Step S421: Settlement.
Step S422: A receipt is issued by the printing unit 213. Then, the flowchart of FIG. 11 ends. In addition, you may issue the receipt which printed the product registered on the salesclerk side and the product registered on the customer side so that distinction was possible. For example, a mark such as a US mark or an asterisk, an underline, or the like may be added to any one of the products registered on the store clerk side or the customer side. Further, for example, a receipt may be issued in which the print area of the product registered on the customer side and the print area of the product registered on the store clerk side are separated. That is, you may issue the receipt which printed the goods registered on the customer side, and the goods registered on the store clerk side in a different field.

  FIG. 12 is an example of registration information. The POS terminal 20 may generate registration information as shown in FIG. 12, for example, instead of the registration information shown in FIG. The registration information shown in FIG. 12 stores a transaction number, transaction date and time, operation mode, product registrant, product code, product name, unit price, number, and registration classification. The operation mode is information indicating the current operation mode of the POS terminal 20 (when the registration information is generated). The product registrant is a registrant who registered the product. The registration classification is information indicating whether registration is performed on the clerk side or on the customer side. When registering at the clerk side, the registration category “1” is stored, and when registering at the customer side, the registration category “2” is stored.

  The registration information shown in FIG. 12 is registered with “Japanese style prime yakisoba A” of the product code “SC1111” in step S411 of FIG. 11 (registration processing based on customer-side scanning, etc.), and then in step S401. (Star 4 (1 mm)) of the product code “SC1023” is registered in (registration processing based on scan etc. on the store clerk side), and subsequently, “B mountain natural water (1) of the product code“ SC4788 ”is registered in step S411. .5L) "is registered, followed by registration of the product code" SC6500 "" Gold Bento "in step S401, and subsequently the registration of product code" SC3620 "" C Chocolate "in step S411. It is an example of the registration information produced | generated.

  That is, the POS terminal 20 generates registration information of the registration category “1 (sales clerk side)” in the process of step S401 for the product (star 4 (1 mm), glue lunch) scanned by the clerk side scanner unit 212. . On the other hand, the POS terminal 20 uses the registration category “2 (”) in the process of step S411 for the products scanned by the customer-side scanner unit 206 (Japanese-style large serving yakisoba A, natural water of B mountain (1.5 L), C chocolate). Customer registration) "is generated.

  FIG. 13 is a display example on the clerk side and on the customer side. Specifically, FIG. 13A is an example of a registration screen displayed on the clerk side display unit 210. FIG. 13B is an example of a registration screen displayed on the customer side display unit 205.

  For example, when “C chocolate” is scanned by the customer side scanner unit 206 in step S410 of FIG. 11, the POS terminal 20 refers to the registration information (specifically, the registration category) shown in FIG. In FIG. 13, a registration screen as shown in FIG. 13A is displayed on the clerk side display unit 210, and a registration screen as shown in FIG. 13B is displayed on the customer side display unit 205 in step S413.

  As shown in FIG. 13 (A), on the clerk side (the clerk side display unit 210), the product (star 4 (1 mm), glue lunch) registered on the clerk side (self side) is a normal mode (normal size) ) And products registered on the customer side (partner side) (Japanese-style large servings yakisoba A, natural water (1.5 L) of mountain B, C chocolate) are displayed in an emphasized form (enlarged size). In the upper part, the last registered product (paste lunch) is displayed on the store clerk side (reference number NI). In the lower part, a notification is made that the current mode (double scan mode) is set (reference M).

  As shown in FIG. 13 (B), on the customer side (customer side display unit 205), products registered on the customer side (own side) (Japanese-style large baked noodles A, B mountain natural water (1.5L)) , C chocolate) is displayed in the normal mode (normal size), and the product (star 4 (1 mm), glue lunch) registered on the store clerk side (partner side) is displayed in the emphasized mode (enlarged size). In the upper part, the product (C chocolate) registered last on the customer side is displayed (reference symbol NI). In the lower part, a notification is made that the current mode (double scan mode) is set (reference M).

  That is, based on the fact that the first product “Japanese-style prime yakisoba A” has been scanned on the customer side (step S410; YES), the clerk side (the clerk-side display unit 210) displays “Japanese-style large serving yakisoba”. "A" is highlighted (step S412), and "Japanese style large yakisoba A" is normally displayed on the customer side (customer side display unit 205) (step S413). Subsequently, based on the fact that the second product “Star 4 (1 mm)” is scanned on the clerk side (Step S400; YES), the clerk side (the clerk side display unit 210) displays “Star”. 4 (1 mm) ”is normally displayed (step S402), and“ star 4 (1 mm) ”is highlighted on the customer side (customer side display unit 205) (step S403). Subsequently, based on the fact that the third product, “B Mountain Natural Water (1.5 L)” was scanned on the customer side (step S410; YES), the clerk side (the clerk side display unit 210) ) “B Mountain Natural Water (1.5 L)” is highlighted (step S 412), and “B Mountain Natural Water (1.5 L)” is normally displayed on the customer side (customer side display unit 205). (Step S413). Subsequently, based on the fact that the fourth product “paste lunch” is scanned on the clerk side (step S400; YES), “paste lunch” is displayed on the clerk side (clerk side display unit 210). It is normally displayed (step S402), and “paste lunch” is highlighted on the customer side (customer side display unit 205) (step S403). Subsequently, based on the fact that “C chocolate” which is the fifth product is scanned on the customer side (step S410; YES), “C chocolate” is displayed on the clerk side (the clerk side display unit 210). It is highlighted (step S412), and “C chocolate” is normally displayed on the customer side (customer side display unit 205) (step S413).

  As shown in FIG. 13 (A), on the clerk side, products registered on the clerk side and on the customer side (Japanese-style large yakisoba A, star 4 (1 mm), B mountain natural water (1.5 L), glue (Bento, C chocolate) is displayed according to the registered order (Japanese style prime yakisoba A → star 4 (1 mm) → mountain natural water (1.5 L) → paste lunch → C chocolate). Therefore, as a matter of course, even if attention is paid only to the products registered on the store clerk side (star 4 (1 mm), glue lunch), the order in which the products (star 4 (1 mm), glue lunch) are registered (star 4) (1mm) → Nori Bento) Displayed and registered on the customer's side (Japanese-style large yakisoba A, B mountain natural water (1.5L), C chocolate) Large prime yakisoba A, natural water of mountain B (1.5 L), C chocolate) are displayed according to the registered order (Japanese-style large yakisoba A → natural water of mountain B (1.5 L) → C chocolate). The same applies to the customer side (see FIG. 13B). The same applies to the display example of FIG. 14 (described later).

  Moreover, as shown in FIG. 13 (A) and FIG. 13 (B), the product registered on the store clerk side (star 4 (1 mm), glue lunch) and the product registered on the customer side (Japanese-style large serving yakisoba) Since the display mode is different from A and B natural water (1.5L), C chocolate), the whole registration order (Japanese style large yakisoba A → Star 4 (1mm) → B natural water (1.5L) → Nori lunch box → C chocolate), registration order on the clerk side (Star 4 (1mm) → Nori lunch box) and registration order on the customer side (Japanese-style large yakisoba A → B mountain natural water (1.5L) → C chocolate ) Is also easier to recognize. The same applies to the display example of FIG. 14 (described later).

  In FIG. 13, the characters are enlarged and displayed as the highlight display, but the characters may be displayed thicker instead of or in addition to the enlarged characters.

[Other display examples 1]
The display on the clerk side and the customer side in the double scan mode is not limited to that described with reference to the display example of FIG. FIG. 14 shows another display example on the clerk side and on the customer side. Specifically, FIG. 14A is an example of a registration screen displayed on the clerk side display unit 210. FIG. 14B is an example of a registration screen displayed on the customer side display unit 205.

  For example, when “C chocolate” is scanned by the customer side scanner unit 206 in step S410 of FIG. 11, the POS terminal 20 refers to the registration information (specifically, the registration category) shown in FIG. 14A, a registration screen as shown in FIG. 14A may be displayed on the store clerk side display unit 210, and a registration screen as shown in FIG. 14B may be displayed on the customer side display unit 205 in step S413.

  As shown in FIG. 14 (A), on the clerk side (the clerk side display unit 210), the product (star 4 (1 mm), glue lunch) registered on the clerk side (self side) is a normal mode (normal size) ) And products registered on the customer's side (the other party) (Japanese style prime yakisoba A, natural water of B mountain (1.5L), C chocolate) are highlighted (with star sign, one character forward) ) Is displayed. Note that “up by the first character” means to move up the display start position by one character (just to the left or close it).

  As shown in FIG. 14 (B), on the customer side (customer side display unit 205), the products registered on the customer side (own side) (Japanese-style large servings yakisoba A, natural water of mountain B (1.5L)) , C chocolate) is displayed in the normal mode (normal size), and the merchandise (star 4 (1 mm), glue lunch box) registered on the store clerk side (partner side) is emphasized mode (with star sign, one character forward) ) Is displayed.

  In FIG. 14, all three contents (character size, asterisk, character advance) are performed as highlighting, but instead of performing all three, one or two may be performed. Good. In addition, other marks (such as rice marks) may be added instead of the star. Further, as a highlight display, instead of or in addition to the above, a highlight display by a background color may be performed, or an underline may be added.

  In the flowchart of FIG. 11 and the display examples of FIG. 13 and FIG. 14, the example in which the product registered on the own side is displayed in the normal mode and the product registered on the other side is displayed in the emphasized mode. However, conversely, the product registered on the partner side may be displayed in the normal mode, and the product registered on the own side may be displayed in the emphasized mode.

  In addition, in the store clerk side display unit 210, instead of highlighting one of the products registered on the own side or the products registered on the other side, it is simply determined on which side the product is registered. You may display so that identification is possible. For example, in the column of products registered on your side, “Clerk” is displayed between the product name and price, and in the column of products registered on the other side, “ “Customer” may be displayed. It is also possible to use a badge-like image displaying “Clerk” or a badge-like image displaying “Customer”.

  Further, instead of or in addition to the above, in the customer side display unit 205, instead of highlighting any one of the products registered on the own side or the products registered on the other side, Which side is registered may be displayed in an identifiable manner. For example, “Customer” is displayed between the product name and price in the product column registered on your side, and “Product” is displayed between the product name and price in the product column registered on the other side. “Clerk” may be displayed.

[Other display example 2]
The display on the clerk side and the customer side in the double scan mode is not limited to that described using the display example of FIG. 13 or the display example of FIG. FIG. 15 shows another display example on the clerk side and the customer side. Specifically, FIG. 15A is an example of a registration screen displayed on the clerk side display unit 210. FIG. 15B is an example of a registration screen displayed on the customer side display unit 205.

  When the fifth product “C chocolate” is scanned by the customer-side scanner unit 206, the POS terminal 20 displays a registration screen as shown in FIG. A registration screen as shown in FIG.

  FIG. 16 is a part of a flowchart corresponding to another display example 2. Specifically, FIG. 16A is obtained by replacing the processing of the rectangle P in the flowchart of FIG. That is, the POS terminal 20 executes step S1402 of the flowchart of FIG. 16A instead of step S402 of the flowchart of FIG. 11, and replaces step S403 of the flowchart of FIG. 11 with the step of the flowchart of FIG. Step S1403 is executed, step S1412 of the flowchart of FIG. 16A is executed instead of step S412 of the flowchart of FIG. 11, and step S1413 of the flowchart of FIG. 16A is replaced with step S413 of the flowchart of FIG. May be executed.

  That is, for example, when “C chocolate” is scanned by the customer-side scanner unit 206 in step S410 (FIG. 11), the POS terminal 20 refers to the registration information (specifically, the registration category) shown in FIG. In step S1412 (FIG. 16A), a registration screen as shown in FIG. 15A is displayed on the clerk side display unit 210, and in step S1413 (FIG. 16A), the customer side display unit 205 displays FIG. A registration screen as shown in (B) may be displayed.

  As shown in FIG. 15 (A), in the first area H1 on the clerk side (the clerk side display unit 210), products (star 4 (1 mm), glue lunch) registered on the clerk side (self side) are stored. In the second area H2 on the store clerk side (store clerk side display unit 210), displayed in the normal mode (normal size), the products registered on the customer side (partner side) (Japanese-style large serving yakisoba A, natural water of B mountain) (1.5 L), C chocolate) is displayed in an emphasized manner (enlarged size). In addition, in order to show the display contents in each area (first area H1, second area H2), a title “store clerk registered product” is displayed at the top of the first area H1, and at the top of the second area H2. The title “Customer Registration Product” is displayed.

  As shown in FIG. 15 (B), in the first area H1 of the customer side (customer side display unit 205), products registered on the customer side (own side) (Japanese-style large-scale yakisoba A, natural water of B mountain) (1.5L), C chocolate) is displayed in the normal mode (normal size), and in the second area H2 on the customer side (customer side display unit 205), the product ( Star 4 (1 mm), paste lunch) is displayed in an emphasized manner (enlarged size). In addition, in order to show the display contents in the respective areas (the first area H1 and the second area H2), the title “product registered by the customer” is displayed at the top of the first area H1, and the top of the second area H2. The title “Product registered by the clerk” is displayed.

  On the clerk side, as shown in FIG. 15 (A), the order (star 4 (1 mm) → registered product (star 4 (1 mm), glue lunch box) registered on the clerk side in the first region H1 → The order in which the products (Japanese-style large serving yakisoba A, B mountain natural water (1.5 L), C chocolate) registered in the second area H2 on the customer side are registered (Japanese-style large serving yakisoba A) → It is displayed according to natural water of mountain B (1.5L) → C chocolate). The same applies to the customer side (see FIG. 15B).

  FIG. 15 illustrates an example in which the product registered on the own side is displayed in the first area H1 (left side area) and the product registered on the other side is displayed in the second area H2 (right side area). However, conversely, it operates as shown in FIG. 16 (B), the product registered on its own side is displayed in the second area H2 (right side area), and the product registered on the partner side is displayed in the first area H1. You may display in (left area).

  FIG. 16B is obtained by replacing the processing of the rectangle P in the flowchart of FIG. That is, the POS terminal 20 executes step S2402 of the flowchart of FIG. 16B instead of step S402 of the flowchart of FIG. 11, and replaces step S403 of the flowchart of FIG. 11 with the step of the flowchart of FIG. Step S2403 is executed, step S2412 of the flowchart of FIG. 16B is executed instead of step S412 of the flowchart of FIG. 11, and step S2413 of the flowchart of FIG. 16B is executed instead of step S413 of the flowchart of FIG. May be executed.

  FIG. 17 is a display example on the clerk side and on the customer side. Specifically, FIG. 17A is an example of a small plan surface displayed on the clerk side display unit 210. FIG. 17B is an example of a small plan surface displayed on the customer side display unit 205.

  For example, the POS terminal 20 displays a registration screen as shown in FIG. 13A on the clerk-side display unit 210 in step S412 of FIG. 11, and shown in FIG. 13B on the customer-side display unit 205 in step S413. After displaying such a registration screen, if it is determined in step S420 that registration of all the purchased products has been completed (step S420: YES), a settlement screen as shown in FIG. Then, a settlement screen as shown in FIG. 17B is displayed on the customer side display unit 205. The customer confirms the total amount on the checkout screen of FIG. 17B and inserts cash into the slot of the change machine 209 or causes the card recognition unit of the card settlement unit 208 to recognize the card. Settlement is made for all items purchased (step S421).

  As shown in FIG. 17 (A), on the clerk side (the clerk side display unit 210), as with the registration screen shown in FIG. The product registered on the customer side (partner side) is displayed in an emphasized manner. A button (reference TG) for returning from the payment screen to the registration screen is arranged at the bottom.

  As shown in FIG. 17B, on the customer side (customer side display unit 205), as with the registration screen shown in FIG. And the product registered on the store clerk side (partner side) is displayed in an emphasized manner.

  17A and 17B is a small plan plane that transitions from the registration screen in FIGS. 13A and 13B, and a small plan plane that transitions from the registration screen in FIGS. 14A and 14B. 15A and 15B is different from the small plan surface shown in FIGS. 17A and 17B. Specifically, the display mode of the product on the small plan surface that transitions from the registration screen of FIGS. 13A and 13B is the same as the display mode of the product on the registration screen of FIGS. 14A and 14B may be displayed in the same manner as the product display mode on the registration screen shown in FIGS. 14A and 14B. ) The display mode of the product on the small plan surface transitioned from the registration screen of (B) may be the same as the display mode of the product on the registration screen of FIGS.

  FIG. 18 is an example of a receipt. For example, when “Star 4 (1 mm)” and “Special Frankfurt” are both undelivered products in step S215 of FIG. 12, for example, the POS terminal 20 issues a receipt as shown in FIG. May be. In the receipt shown in FIG. 18A, “Star 4 (1 mm)” and “Special Frankfurt” are marked with an American mark.

  In addition, for example, in step S422 in FIG. 11, the POS terminal 20 adds a US mark to “Star 4 (1 mm)” and “Gold lunch box” registered on the store clerk side as shown in FIG. 18B. A receipt may be issued. Further, as shown in FIG. 18C, the POS terminal 20 may issue a receipt in which the product registered on the customer side and the product registered on the store clerk side are printed in different areas.

[Operation mode switching according to the presence of shop assistants]
As understood from the above description, in the POS system 1 of the present embodiment, the operation mode related to accounting can be switched among the normal mode, the full self mode, the double scan mode, and the semi self mode.
Under the operation of the POS system 1 of the present embodiment, for example, when a store clerk is located on the store clerk's side and can operate the POS terminal 20, the POS terminal 20 operates in the normal mode, and the store clerk visits the customer. It is preferable to be able to perform accounting while dealing with.
On the other hand, in a situation where the store clerk is away from the POS terminal 20 to perform, for example, other business than accounting, the store clerk cannot perform the product registration operation. In such a situation, the POS terminal 20 is in a state in which the full self mode is set, and even if the store clerk is not present at the store clerk side of the POS terminal 20, the customer who wants to pay can start registering the product himself. It is preferable to do so.
In consideration of the above, when the clerk leaves the POS terminal 20 that has been operated, an operation for instructing switching of the operation mode from the normal mode to the full self mode may be performed. On the other hand, when the clerk moves to the clerk side of the POS terminal 20 in the POS terminal 20 that has been in the full self mode until now, the clerk moves from the full self mode to the normal mode. An operation for instructing switching may be performed.

However, the store clerk may forget the operation for switching the operation mode as described above. In addition, in a situation where the store is very busy, for example, when the POS terminal 20 and other places go away, the store clerk may erroneously determine the operation mode to be set for the above operation. That is, there is a possibility that the operation mode of the POS terminal 20 cannot be appropriately switched by switching the operation mode depending on the operation by the store clerk.
Therefore, in the present embodiment, as described below, the operation mode of the POS terminal 20 is set (switched) according to the presence state of the store clerk.

FIG. 19 is a flowchart illustrating an example of a processing procedure executed by the POS terminal 20 in response to the operation mode switching from the full self mode.
Step S501: Under the state of the full self mode, the POS terminal 20 waits for a state where no store clerk exists on the side of the store clerk (absent) and the store clerk exists. For this reason, the POS terminal 20 detects whether or not the clerk is present on the clerk side of the POS terminal 20 (clerk presence detection).
When starting the product registration operation, the store clerk first performs an operation (login operation) for recognizing his / her store clerk identifier on the POS terminal 20 to be operated. The POS terminal 20 registers the clerk with the clerk identifier recognized in response to the log-in operation as an operator (handler), and then executes a transaction corresponding process for each subsequent transaction. In the login operation, for example, a code indicating a clerk identifier (for example, a barcode, a two-dimensional code, a color code (a code representing information by color arrangement), etc.) attached to the clerk ID by printing or the like is used. Any operation may be used as long as it is read by.
Therefore, as the clerk presence detection in step S501, the POS terminal 20 may detect that a clerk exists because the clerk identifier is recognized by the login operation.

In addition to the login information as described above, the clerk uses the work schedule information registered in advance (or information indicating the current attendance status based on the time card stamping history, etc.) in combination. Presence detection may be performed.
Specifically, for example, in a situation where it is specified that only the “clerk A” is working based on the work schedule information, the POS terminal 20 has the clerk A in one POS terminal 20. In response to the login, it may be detected that a clerk exists for the logged-in POS terminal 20 and that no clerk exists for the other POS terminals 20.

  Step S502: When it is determined that a salesclerk is present, the POS terminal 20 determines whether or not the customer side is in use. That is, in the state of the full self mode, it is determined whether or not processing related to accounting (product registration processing or checkout processing) is being executed according to an operation corresponding to customer accounting.

  Step S503: If it is determined that the customer side is in use, the POS terminal 20 causes the clerk side display unit 210 to display a confirmation screen. The confirmation screen displayed in step S503 notifies the customer of the POS terminal 20 that the customer is currently accounting for the full self mode. This is a screen on which a dialog for confirming with the store clerk whether or not to switch to the normal mode is displayed. On the confirmation screen, for example, a “Yes” button and a “No” button are arranged. The “Yes” button is a button for performing an operation (mode shift instruction operation) for instructing switching (transition) to the normal mode when the store clerk determines that the switch to the normal mode may be performed. The “No” button is a button for performing an operation for instructing to maintain the full self mode (mode maintenance instruction operation) when it is determined that the full self mode should be maintained without switching to the normal mode.

Step S504: Under the state where the confirmation screen is displayed, the POS terminal 20 determines whether or not a mode transition instruction operation has been performed as an operation on the confirmation screen.
If a mode maintenance instruction operation is performed instead of a mode transition instruction operation, the process returns to step S501.

Step S505: If it is determined in step S504 that a mode transition instruction operation has been performed, or if it is determined in step S502 that the customer side is not in use, the POS terminal 20 is set as the normal operation mode. Set the mode. Thereby, the operation mode of the POS terminal 20 shifts from the conventional full self mode to the normal mode.
Step S506: In addition, the POS terminal 20 performs notification (mode transition notification) that switching from the full self mode to the normal mode is performed at a timing corresponding to the transition from the full self mode to the normal mode.
The mode transition notification as step S506 may be performed, for example, as a notification of the completion of the transition to the normal mode at the stage of transition from the full self mode to the normal mode, or before the transition to the normal mode. In the mode state, a transition to the normal mode may be notified. Further, the advance notice of the transition to the normal mode and the notification of the completion of the transition to the normal mode may be sequentially performed.

  When the customer is in full self mode and the customer is in normal mode when the customer is in the normal mode, the customer will not be able to accept the product registration operation, and the subsequent products The registration process is executed in response to a store clerk's product registration operation. In this case, the store clerk may receive a product that has not been registered yet from a customer who has been in the merchandise registration investigation and start a product registration operation for the received product.

For example, when the store clerk tries to perform a product registration operation on the POS terminal 20 in the normal mode, an operation for instructing a transition from the full self mode to the normal mode is performed together with the login operation. The store clerk must perform two operations.
The POS terminal 20 is configured not to accept a store clerk operation unless login is performed, for example. For this reason, a login operation is essential and habitually for shop assistants who want to operate the POS terminal 20.
Therefore, as shown in FIG. 19, by making the transition from the full self mode to the normal mode in accordance with the login operation, the user performs an operation for instructing the transition of the operation mode in addition to the login operation. Not necessary. In this way, in this embodiment, the transition from the full self mode to the normal mode can be performed smoothly.

  The process shown in FIG. 5 shows an example in which the mode is shifted to the normal mode in response to the detection of the presence of a store clerk under the full self mode. However, for example, when the customer side is in use, the mode may be shifted to the double scan mode instead of the normal mode. In the case of shifting to the double scan mode, the store clerk can perform the product registration operation and the customer can also continue the product registration operation. Therefore, the store clerk and the customer can register the product separately. it can.

Next, an example of a processing procedure executed by the POS terminal 20 in response to the operation mode switching from the normal mode will be described with reference to the flowchart of FIG.
Step S601: Under the state of the normal mode, the POS terminal 20 waits until the clerk is absent from the state where the clerk is present on the clerk side. For this reason, the POS terminal 20 detects that the clerk is absent on the clerk side of the POS terminal 20 (absence of clerk).
When the store clerk leaves the POS terminal 20 that has been operated, the store clerk performs a logout operation. Therefore, as the clerk absence detection in step S601, it may be detected that the clerk is absent in response to the clerk performing a logout operation on the POS terminal 20. The logout operation may be an operation on a predetermined button displayed on the store clerk side display unit 210 or a predetermined key arranged on the key operation unit 211, for example.
That is, the POS terminal 20 may determine in step S601 that the store clerk is absent in response to the logout operation being performed.

Step S602: The POS terminal 20 sets the full self mode as the operation mode in response to the fact that there is no store clerk. Thereby, the operation mode of the POS terminal 20 shifts from the normal mode to the full self mode.
Step S603: Also, the POS terminal 20 performs notification (mode transition notification) that switching from the normal mode to the full self mode is performed at a timing corresponding to the transition from the normal mode to the full self mode.
The mode transition notification as step S603 may be performed, for example, as a notification of the completion of the transition to the full self mode at the stage of transition from the normal mode to the full self mode, or before the transition to the full self mode. A transition to the full self mode may be announced in the normal mode state. Further, the advance notice of the transition to the full self mode and the notification of the completion of the transition to the full self mode may be sequentially performed.

For example, when the clerk leaves the POS terminal 20 that has been operated so far, when the clerk performs an operation for instructing the transition from the normal mode to the full self mode together with the logout operation, You must do the operation.
In this case, a logout operation has become a habit for store clerk, but an operation for instructing a shift from the normal mode to the full self mode tends to be forgotten.
Therefore, as shown in FIG. 20, by shifting from the normal mode to the full self mode in response to the logout operation, the user does not perform an operation for instructing the shift of the operation mode in addition to the logout operation. Also good. Thus, in this embodiment, the transition from the normal mode to the full self mode can be performed smoothly.

The clerk presence detection corresponding to step S501 in FIG. 19 and the clerk absence detection corresponding to step S601 in FIG. 20 may be performed as follows.
For example, the store clerk card may have an RFID tag that stores a store clerk identifier. The POS terminal 20 includes a tag reader unit corresponding to the RFID tag. When the clerk approaches a distance within a certain distance from the POS terminal 20, the clerk's card is positioned within the communication distance range of the POS terminal 20, and the POS terminal 20 and the RFID tag of the clerk's card can communicate. When the POS terminal 20 acquires the store clerk identifier through communication with the RFID tag of the store clerk card, the POS terminal 20 detects that the store clerk exists. In this case, the POS terminal 20 may set the clerk with the acquired clerk identifier logged in.
Further, when the clerk leaves the POS terminal 20, the clerk card is located outside the range of the communication distance of the POS terminal 20, and the POS terminal 20 and the RFID tag of the clerk card cannot communicate. The POS terminal 20 detects that the store clerk is not present in response to the communication with the RFID tag of the store clerk corresponding to the store clerk identifier of the store clerk who has been logged in until now. In this case, the POS terminal 20 may be processed as having transitioned to the logout state.

The store clerk may store a store clerk identifier and may be configured to have a communication function corresponding to short-range wireless communication such as Bluetooth (registered trademark). In this case, the POS terminal 20 may be provided with a communication unit corresponding to Bluetooth.
In this case as well, when the store clerk approaches the POS terminal 20 within a certain distance, the POS terminal 20 and the store clerk can communicate with each other, and the POS terminal 20 acquires the store clerk identifier through communication with the store clerk. In this case as well, the POS terminal 20 may set the clerk with the acquired clerk identifier as logged in.
Further, when the clerk leaves the POS terminal 20, the clerk card is located outside the range of the communication distance of the POS terminal 20, and the POS terminal 20 and the RFID tag of the clerk card cannot communicate. The POS terminal 20 detects that the store clerk is not present in response to the communication with the RFID tag of the store clerk corresponding to the store clerk identifier of the store clerk who has been logged in until now. In this case, the POS terminal 20 may process the logout as being performed.

A human sensor that detects the presence of a person on the clerk side of the POS terminal 20 may be provided. The POS terminal 20 may determine that a store clerk is present when the presence sensor detects the presence of a person.
Further, the POS terminal 20 may determine that the salesclerk does not exist in response to the presence of the person being detected by the human sensor.

In addition, an imaging device may be provided so that a store clerk can perform imaging when performing a product registration operation on the POS terminal 20. The POS terminal 20 may determine that the clerk is in a state where a person is present from a state where no person is present in the captured image captured by the imaging device.
Further, the POS terminal 20 may determine that the clerk is not in the state where the person is present from the state where the person is present in the captured image captured by the imaging device. Good.

In addition to directly detecting the presence of a person using a human sensor or an imaging device as described above, detection (input) regarding the presence of a person is performed using a human sensor or an imaging device as described below. You may be broken.
That is, the POS terminal 20 determines the position of the store clerk based on one or more human sensors provided to detect, for example, a customer flow line in the store, a human detection signal obtained by an imaging device, a captured image, or the like. The POS terminal 20 may determine based on the determined position of the store clerk that the store clerk is present corresponding to the POS terminal 20 or that the store clerk is not present.

Further, the device that determines whether or not the store clerk exists or is not present is not limited to the POS terminal 20 that switches the operation mode according to the determination result.
In other words, the situation of the presence of a person corresponding to a certain POS terminal 20 may be determined by another POS terminal 20 or a host device of the POS terminal 20. The host device may be a store controller 10 provided in the store, or a management device or server provided in the store or outside the store.
One POS terminal 20 receives a determination result regarding the presence of a person corresponding to itself from another POS terminal 20 or a host device, and switches the operation mode according to the input determination result. Good.

  Further, the POS terminal 20 may determine that the store clerk does not exist in response to the elapse of a certain time since the last operation performed on the store clerk side.

<Modification>
The embodiment of the present invention has been described above, but the configuration of the device, the configuration of data, the flow of processing, the display and output modes, and the like can be changed and modified as appropriate, for example, as in the following modifications. .

[First Modification]
[Operation mode]
The POS terminal 20 shifts to the full self mode when it remains unused (see FIG. 9A), but when the clerk is using (except for the operation to set the full self mode), the full self mode is set. Transition to the mode may be prohibited.

  In addition, the clerk code is read to shift from the full self mode to the double scan mode (see FIG. 9B), but instead of reading the clerk code, the display screen of the clerk side display unit 210 is touched. Thus, the full self mode may be shifted to the double scan mode. When operating in the full self mode, a screen on which buttons corresponding to each store clerk are arranged may be displayed on the store clerk side display unit 210, and the store clerk may be identified according to the touched button on the screen. . Further, the full self mode may be shifted to the double scan mode by operating the key operation unit 211. A button corresponding to each store clerk may be arranged in the key operation unit 211, and the store clerk may be specified according to the button operated in the key operation unit 211.

  Further, after the POS terminal 20 operating in the normal mode transmits a transition instruction to the other POS terminals 20, if the local POS terminal 20 is processing, the POS terminal 20 shifts to the semi-self mode (registration-only mode) after the processing ends ( (See FIG. 10 (A)), it may forcibly (immediately) transition to the semi-self mode (registration-only mode) after transmission of the transition instruction. For example, when a customer is executing a checkout process on the customer side, if a shift instruction is transmitted, the normal mode is immediately shifted to the semi-self mode (registration-only mode), while the checkout process being executed is completed. , It may be possible to execute continuously.

  Further, after the POS terminal 20 operating in the normal mode or the like receives a shift instruction from another POS terminal 20, the POS terminal 20 shifts to a semi-self mode (settlement-only mode) after the process ends if the POS terminal 20 is processing. (Refer to FIG. 10 (B)), it may be forcibly (immediately) shifted to the semi-self mode (settlement only mode) after receiving the shift instruction. For example, when the store clerk is performing registration processing on the store clerk side, if the shift instruction is received, the mode immediately shifts from the normal mode to the semi-self mode (settlement only mode), while the registration process being executed is completed. , It may be possible to execute continuously.

  Further, the POS terminal 20 operating in the full self mode may be caused to function as a semi self mode (settlement only mode). That is, the POS terminal 20 operating in the semi-self mode (registration-only mode) transmits registration information to the POS terminal 20 operating in the semi-self mode (accounting-only mode) and operates in the semi-self mode (accounting-only mode). The POS terminal 20 causes the POS terminal 20 to execute the settlement process. The POS terminal 20 operating in the semi-self mode (registration-only mode) transmits registration information to the POS terminal 20 operating in the full self-mode and operates in the full self-mode. The POS terminal 20 that performs the checkout process may be executed. In addition, when the customer is not operating in the POS terminal 20 that operates in the full self mode, the registration information may be transmitted from the POS terminal 20 that operates in the semi-self mode (registration-only mode). You may not be able to send registration information when the customer is performing an operation, or even if the customer is performing an operation, send the registration information so that payment is performed immediately after the customer's operation is completed. Also good.

Further, a transmission button may be displayed on the clerk-side display unit 210 of the POS terminal 20 that is a transmission source of registration information in relation to transmission of registration information. The clerk-side display unit 210 displays transmission buttons for all other POS terminals on the LAN 11 so that each POS terminal can be identified (for example, terminal numbers such as “Register 1” and “Register 2” are attached). The POS terminal can be identified by the transmission button of the POS terminal that can be the destination (POS terminal 20 operating in the semi-self mode (settlement-only mode), POS terminal 20 in the full self mode). May be displayed.
One or more POS terminals 20 that are permitted as transmission destinations of registration information from the POS terminal 20 are determined in advance (that is, coupling between the registration side and the settlement side is determined in advance), and based on this, a transmission button May be displayed.

  In addition, a button corresponding to the POS terminal 20 that can currently transmit registration information and a button corresponding to the POS terminal 20 that cannot transmit registration information may be displayed in different display modes. For example, a button corresponding to the POS terminal 20 that can transmit registration information is displayed in a normal display mode, and a button corresponding to the POS terminal 20 that cannot transmit registration information is displayed in a special display mode (for example, gray down). May be displayed. Currently, the buttons corresponding to the POS terminals 20 that cannot transmit registration information may be disabled or prohibited (for example, the touch may be disabled).

  In addition, the status (for example, waiting, in use, near end, near full, offline, etc.) of each POS terminal 20 that is a transmission destination of registration information may be notified. For example, the status of each POS terminal 20 is shared in the LAN 11 (for example, transmission / reception of information indicating the status, centralized management in the store controller 10 or one representative POS terminal 20), and the like ( Alternatively, information indicating the status of each POS terminal 20 (for example, a badge-like image displaying “standby”, “in use”, “near end”, etc.) may be displayed. In the case of the POS terminal 20 operating in the full self mode, the POS terminal 20 is in a standby state when the customer is not operating, when the customer starts registration, the standby state is in use. Become inside. The in-use may be divided into registration and settlement before and after the operation of the registration completion key (subtotal key).

  Further, when the customer is using the POS terminal 20 that operates in the full self mode, the transition to the normal mode may be restricted. For example, the transition to the normal mode is permitted when the customer is paying in the full self mode, and the transition to the normal mode is prohibited when the customer is performing the registration process in the full self mode (at least an immediate transition) May be prohibited).

  Further, although the POS terminal 20 has been described that the operation mode shifts according to an explicit mode shift operation by the store clerk, the operation mode before the shift (current operation mode), the shift destination even in the explicit mode shift operation The operation may be limited depending on the operation mode, the operation status, and the like.

  The operation mode of the POS terminal 20 may be scheduled according to the work situation of the clerk (attendance situation, work schedule, work schedule). However, depending on the operation mode before the transition (current operation mode), the operation mode of the transition destination, the operation state, and the like, there may be a case where the control is performed according to the scheduling or a case where the control is not performed according to the scheduling.

  As an example of the operation mode notification, the example in which the POS terminal 20 displays the operation mode on the display unit (the clerk side display unit 210 and the customer side display unit 205) has been described, but the notification mode of the operation mode is not limited thereto. For example, the POS terminal 20 is provided with Patlite (registered trademark), a display board, or the like (or connected to the POS terminal 20), and the operation mode of the POS terminal 20 is notified by the patrol light, the display board, or the like. May be. Further, the POS system 1 may include a patrol light, a display board, or the like (or connect the patrol light, the display board, or the like to the LAN 11), and notify the operation mode of each POS terminal 20 in the store by the patrol light, the display board, or the like. . By using a patrol light, a display board, or the like, the operation mode can be visually recognized even from a distance (a position away from the store clerk side display unit 210).

[Second Modification]
[Display in double scan mode]
In the flowchart (see FIG. 11), when either the subtotal key displayed on the store clerk side display unit 210 or the registration completion key displayed on the customer side display unit 205 is pressed (step S420: YES). The small plan surface (see FIG. 17) is displayed. In other words, the merchandise registration is completed by either the clerk side (subtotal key) or the customer side (registration completion key). However, the mode for completing the product registration (operation for displaying the small plan surface) is not limited to this.

  For example, the small plan surface may be displayed only when a subtotal key on the store clerk side is pressed. That is, the customer may be allowed to perform an operation for completing the product registration only by the store clerk without performing the operation for completing the product registration. In this aspect, the customer side display unit 205 may display the registration completion key in a display mode (for example, gray down) indicating that the operation is not valid, or may not display the registration completion key.

  Further, when both the subtotal key on the store clerk side and the registration completion key on the customer side are pressed, a small plan surface may be displayed. That is, when the subtotal key is pressed first on the clerk side (when the subtotal key is pressed), the sub-plan is displayed at the timing when the registration completion key is pressed on the customer side. When the registration completion key is pressed first on the customer side (when the registration completion key is pressed), the small plan screen is displayed at the timing when the subtotal key is pressed on the clerk side. May be.

  In a mode in which a small plan surface is displayed when both the subtotal key on the clerk side and the registration completion key on the customer side are pressed, when one of the subtotal key and the registration completion key is pressed, the fact that the key has been pressed May be notified to the other. For example, if the subtotal key is pressed first, a message indicating that the subtotal key has been pressed (that is, a product registration operation by the store clerk. For example, a message such as "Product registration by the store clerk is over") ) May be displayed on the customer display unit 205. On the other hand, if the registration completion key is pressed first, it means that the registration completion key has been pressed (that is, the product registration operation by the customer. For example, “Product registration by customer has ended” Message or the like) may be displayed on the clerk side display unit 210.

  When the subtotal key is pressed, instead of or in addition to displaying on the customer display unit 205 that the subtotal key has been pressed, the registration completion key displayed on the customer display unit 205 is displayed. The display mode may be displayed in a highlighted mode (flashing, etc.) until the registration completion key is pressed. Similarly, when the registration completion key is pressed, instead of or in addition to displaying on the clerk side display unit 210 that the registration completion key is pressed, a subtotal displayed on the clerk side display unit 210 is displayed. You may make it display the display mode of a key by an emphasis mode (flashing etc.) until the said subtotal key is pressed.

  In a mode in which a small plan surface is displayed when both the subtotal key on the clerk side and the registration completion key on the customer side are pressed, the registration completion key is prohibited from being pressed until the subtotal key is pressed (eg, grayed out, hidden) Etc.), and after the subtotal key is pressed, the registration completion key may be permitted to be pressed (for example, displayed in a pressable display mode). Alternatively, pressing of the subtotal key may be prohibited until the registration completion key is pressed, and pressing of the subtotal key may be permitted after the registration completion key is pressed.

  In a mode in which a small plan surface is displayed when both the subtotal key on the clerk side and the registration completion key on the customer side are pressed, even after the subtotal key on the clerk side is pressed, before the registration completion key on the customer side is pressed In some cases, registration may be allowed in a state where registration is temporarily completed on the clerk side. That is, when the subtotal key is pressed on the clerk side, the fact that the subtotal key is pressed is notified to the other party (customer side), but even after the subtotal key is pressed, the small plan surface is displayed. During the period (before the registration completion key on the customer side is pressed), the product before the product registration of the customer may be registered (additionally registered) on the clerk side.

  In addition, in the case of registering an additional product after performing an operation for completing the product registration on the store clerk side (when the product is additionally registered in the registration provisional completion state), in order to display a small plan surface, The store clerk needs to complete the product registration again (pressing the subtotal key). In other words, after additional registration of the product, the small plan screen is displayed when both the sub-total key on the store clerk side and the registration completion key on the customer side are both pressed. Instead of the above, an operation for completing the product registration again on the store clerk side may be unnecessary. In other words, after additional registration of the product, the small plan surface may be displayed if the registration completion key is pressed on the customer side without pressing the subtotal key again on the store clerk side.

  In addition, when the subtotal key is pressed and before the registration completion key is pressed, the customer's product may be additionally registered on the store clerk side as described above. However, as described with reference to FIG. In this way, the product registration of the next customer may be possible. When the subtotal key is pressed and before the registration completion key is pressed, the clerk-side display unit 210 declares whether to register additional products for the customer or products for the next customer ( Designation). For example, the declaration may be made by a button or the like displayed on the clerk side display unit 210.

  In the double scan mode, when the same product is scanned on the customer side and the clerk side, it may be notified that the same product has been scanned on the customer side and the clerk side. For example, a message such as “Same product has been scanned” or “This is the scan for the 0th time” may be displayed on the display unit. The message display destination may be at least on the store clerk side. In other words, when the same product is scanned on the customer side and the store clerk side, a message is always displayed on the store clerk side display unit 210, but a message may or may not be displayed on the customer side display unit 205. May be. For example, when the same product as the product already scanned on the customer side is scanned on the clerk side, a message is displayed on the clerk side display unit 210, and the same product as the product already scanned on the clerk side is displayed on the customer side. Message may be displayed on the customer side display unit 205 and the store clerk side display unit 210. Further, for example, it may be controlled whether or not the above-mentioned message is displayed on the customer-side display unit 205 in accordance with a setting operation (or switching operation) by a store clerk.

  In addition, in the above, during the registration of the product (registration screen) and after registration (small plan surface), the store clerk side display unit 210 registered the product registered on its own side (store clerk side) and the partner side (customer side). The product is displayed in a different display mode (see FIG. 13 (A), FIG. 14 (A), FIG. 15 (A), FIG. 17 (A)), and registered on the customer side display unit 205 on its own side (customer side). The displayed merchandise and the merchandise registered on the other party (clerk side) are displayed in different display modes (FIGS. 13B, 14B, 15B, and 17B). Reference), the display mode in the clerk side display unit 210 and the customer side display unit 205 is not limited to this.

  For example, the clerk side display unit 210 does not display the product registered on the partner side (customer side) but displays the product registered on the own side (store clerk side), and the customer side display unit 205 displays the product registered on the partner side (clerk side). ) May be displayed without displaying the product registered in (). Alternatively, as shown in FIG. 13A or the like, the clerk side display unit 210 displays the product registered on the own side (store clerk side) and the product registered on the other side (customer side) in different display modes. The customer display unit 205 may display the product registered on the customer side (customer side) without displaying the product registered on the partner side (store clerk side). Alternatively, the clerk side display unit 210 does not display the product registered on the partner side (customer side) but displays the product registered on the own side (store clerk side), and the customer side display unit 205 displays the product registered in FIG. As shown in the above, the product registered on the own side (customer side) and the product registered on the other side (store clerk side) may be displayed in different display modes.

  In the clerk side display unit 210, it is possible to declare (specify) whether or not to display the product registered on the partner side (customer side) on the own side (the clerk side display unit 210). Good. In addition to or in addition to the above, in the store clerk side display unit 210, a declaration (whether or not to display) the product registered on the side (store clerk side) on the partner side (customer side display unit 205) ( Designation). In addition to or in addition to the above, the customer display unit 205 declares whether or not to display the product registered on the other party (store clerk side) on the customer side (the customer display unit 205). (Designation) may be possible. Any of them may be declared by a button or the like displayed on the screen.

  Further, during product registration, for example, as shown in FIG. 15, the product registered on the own side and the product registered on the other side are displayed in different display areas, and after product registration, for example, FIG. As shown in FIG. 4, the product registered on the own side and the product registered on the other side may be displayed in a common display area. In other words, for example, when a transition is made from the registration screen to the small plan surface by pressing the subtotal key, etc., the product registered on the own side and the other side registered on the registration screen before pressing the subtotal key, etc. The commercialized product may be displayed in a common display area on the small plan surface after the subtotal key or the like is pressed. When the registration screen button (symbol TG in FIG. 17A) is pressed to shift to the registration screen from the small plan surface, the user himself / herself displayed in the common display area on the small plan surface before the registration screen button is pressed. The registered product and the product registered on the other side may be displayed in different display areas on the registration screen after the registration screen button is pressed.

  It should be noted that in the clerk-side display unit 210, regarding the display mode during the product registration or after the product registration in the clerk-side display unit 210 or the customer-side display unit 205, the product registered on the own side and the other party are registered. It may be possible to declare (specify) whether to display the product in a different display area or in a common display area. In addition to or in addition to the above, in the customer-side display unit 205, the customer-side display unit 205 can display the product registered on its own side and the other party regarding the display mode during product registration or after product registration. It may be possible to declare (specify) whether to display the registered product in a different display area or in a common display area. Any of them may be declared by a button or the like displayed on the screen.

[Third Modification]
[About analysis etc.]
In the POS system 1, an electronic journal may be stored and used for various analyses. The electronic journal may include various information shown in FIGS. 13, 14, 12, etc., output information shown in FIGS. 16, 18, etc. (including information related to customers). Good. For example, the POS terminal 20 (or the store controller 10) stores an electronic journal for each transaction, and the operation status of each operation mode (for example, by time of day, by person in charge, or unconditional, for each mode). Operating hours, etc.), actual sales of products (for example, sales volume, etc.), operation status of vouchers (for example, the number of vouchers issued, the ratio of vouchers issued relative to the number of products sold, after the voucher is issued) The time required to deliver the product) and the registration status of the store clerk and customers in the double scan mode (ratio of the number of product registrations between the store clerk and customers, etc.) (If the gender age can be ascertained, it may be by customer). The analysis result may be output to a list or the like.

  In addition, for example, by storing the registration start time (in seconds) of the first product in each transaction and the display start time of the small plan surface in the electronic journal, for example, by operation mode (for example, by purchase number by operation mode) ) (For example, the time required until the registration process is completed (until the start of the small plan surface display)) may be analyzed.

[Fourth Modification]
In the above description, the current operation mode of the own POS terminal 20 is displayed (for example, reference numeral M in FIG. 17). For example, information on the operation mode in another POS terminal 20 is acquired via the LAN 11. Thus, the current operation mode of the other POS terminal 20 may be displayed.

[Fifth Modification]
FIG. 21 shows an arrangement example of the POS terminal 20 in the store under this modification. Specifically, FIG. 21A shows a configuration including four POS terminals 20 in the full self mode (hereinafter, this configuration is referred to as configuration A). The configuration A is a configuration suitable for a time zone that is relatively not busy.
In FIG. 1, three POS terminals 20-1 to 20-3 are shown, but in the same figure, POS terminals 20-1 to 20-4 are shown as the four POS terminals 20.

  A customer who has finished shopping at the sales floor heads to one of the four POS terminals 20 in the full self mode, and the customer registers the merchandise and performs payment. The customer may select a POS terminal 20 (such as a vacant POS terminal 20) that performs processing (registration, settlement) at the customer's own discretion, but a store clerk (not shown in FIG. 21 (A)) You may give instructions to customers who have finished. Further, an attendant dedicated terminal (not shown) may be installed, and the POS terminal 20 to be processed may be guided to a customer who has finished shopping on the display screen of the terminal. In the case of Configuration A, as shown in FIG. 21 (A), four systems of accounting leads (flow lines) are formed.

  In addition, a configuration including the plurality of POS terminals 20 (the configuration A or the configuration B described later) may be referred to as an “island”.

  FIG. 21B shows a configuration comprising two POS terminals 20-1 and 20-3 in the normal mode and two POS terminals 20-2 and 20-4 in the semi-self mode (settlement-only mode) (hereinafter referred to as “the POS terminals 20-2 and 20-4”). The configuration is referred to as configuration B). The configuration B is a configuration suitable for a relatively busy time zone. In the case of Configuration B, as shown in FIG. 21 (B), two systems of accounting conductors are formed: accounting conductors by POS terminals 20-1 and 20-2 and accounting conductors by POS terminals 20-3 and 20-4. However, the POS terminals 20-1 and 20-3 on the upstream side of each accounting lead are in the normal mode, and the POS terminals 20-2 and 20- on the downstream side of the respective accounting leads are. 4 is a semi-self mode (settlement-only mode).

  A customer who has finished shopping at the sales floor goes to one of the two POS terminals 20 in the normal mode, and the store clerk registers the product. After the registration by the store clerk, the registration information is transmitted to the POS terminal 20 in the semi-self mode (settlement-only mode), so the customer himself / herself performs the settlement. The registration information is generally transmitted to the POS terminal 20 in the semi-self mode (settlement-only mode) of the same lane so as not to disturb the accounting lead shown in the figure, but the semi-self mode (settlement-only mode) of other lanes. It is also possible to transmit to the POS terminal 20.

  Next, a general operation in a case where registration information is transmitted to the POS terminal 20 in the semi-self mode (settlement only mode) of the same lane will be described.

(1) The POS terminal 20 in the normal mode (or a clerk of the device, hereinafter the same in the description) starts registering a product for a customer (customer 1) on the clerk side. The POS terminal 20 in the normal mode transmits the registration information of the customer 1 to the POS terminal 20 in the semi-self mode (settlement only mode) that is another terminal after the product registration of the customer 1 is completed.
(2) The POS terminal 20 in the normal mode that has transmitted the registration information of the customer 1 starts registering the product of the next customer (customer 2) on the store clerk side. In the normal mode POS terminal 20, after customer 2's product registration is completed, customer 1 who is the previous customer is still in semi-self mode (settlement-only mode) (when customer 1's settlement at another terminal is not completed) The customer 2 pays out at the customer side of the terminal. In addition, when the next customer (customer 3) appears during customer 2's checkout, the clerk side is vacant and registration of the customer 3's product is started. In other words, the POS terminal 20 in the normal mode can execute the customer 2 settlement process on the customer side, while the store clerk can perform the customer 3 registration process (the customer 2 settlement and the customer 3 registration are performed in parallel). Can be processed).
(3) The POS terminal 20 in the normal mode, when the customer 2 who is the previous customer is still on the customer side of the own terminal after the product registration of the customer 3 is completed (when the settlement of the customer 2 in the own terminal is not completed) ), The registration information of the customer 3 is transmitted to the POS terminal 20 in the semi-self mode (settlement only mode) which is another terminal.

  Subsequently, switching from the configuration A to the configuration B and switching from the configuration B to the configuration A will be described.

  There are two types of methods for switching from configuration A to configuration B (method of switching from configuration B to configuration A). One is a method (individual method) in which a mode switching operation is individually performed in each of a plurality of POS terminals 20 (four in the example of the configuration A and the configuration B) configuring the “island”. The other is a mode switching operation in any one POS terminal 20 (one of four in the example of the configuration A and the configuration B) constituting the “island”. This is a method (batch method) in which mode switching of other POS terminals 20 constituting the “island” is also performed collectively.

  FIG. 22 is an explanatory diagram for explaining mode switching. Specifically, FIG. 22A is an explanatory diagram illustrating mode switching and the like when switching from configuration A to configuration B. More specifically, the column (a) in FIG. 22A describes the individual method in the switching from the configuration A to the configuration B described above. A column (b) in FIG. 22A describes the batch method in switching from the configuration A to the configuration B described above. FIG. 22B is an explanatory diagram illustrating mode switching and the like when switching from configuration B to configuration A. More specifically, the column (c) in FIG. 22B describes the individual method in switching from the configuration B to the configuration A described above. The (d) column in FIG. 22B describes the batch method in switching from the configuration B to the configuration A described above.

  As shown in FIGS. 22 (A) and 22 (B), the collective method is advantageous because it takes less time to switch from the configuration A to the configuration B or the configuration B to the configuration A than the individual method.

  In order to realize the collective method, each POS terminal 20 stores information indicating how the mode is switched when a switching operation is performed or when a switching instruction is received (or other By switching to the terminal), the operation mode is switched to an appropriate operation mode (the operation mode shown in the (b) column of FIG. 22A or the (d) column of FIG. 22A) according to the switching operation or the switching instruction. What should I do?

  Further, as shown outside the table of FIG. 22, the mode switching operation in the individual method (same as the collective method) may be performed by a hardware key or a software key (described later). In addition, as an individual method (same as a collective method), instead of or in addition to the mode switching operation, individual operation modes may be switched by a mode switching instruction from a monitoring terminal or a clerk's mobile terminal.

  Further, in the collective method, a specific POS terminal 20 (for example, a POS terminal 20 frequently used by a store manager or the like (a POS terminal 20 arranged in a certain place), a store manager, or the like logs in, instead of any POS terminal 20. The POS terminal 20 or the like) may enable the batch method switching. For example, when a switching button provided in the key operation unit 211 is operated on a specific POS terminal 20, switching by a batch method is executed, but switching is performed on a POS terminal 20 that is not a specific POS terminal 20. When the button is operated, switching by the batch method may not be executed.

  In the collective method, for example, a dedicated button for the collective method (such as a collective button (for example, collective switch button) (see FIG. 3B)) may be prepared in the key operation unit 211.

  Further, the operation using the batch switching button may be effective in a specific POS terminal 20. For example, a batch switching button is arranged on a specific POS terminal 20 (for example, a POS terminal 20 frequently used by a store manager or the like (a POS terminal 20 arranged in a certain place)), and a POS terminal that is not a specific POS terminal 20 The batch switching button may not be arranged at 20. Also, although a batch switching button is arranged in all the POS terminals 20, a specific POS terminal 20 (for example, a POS terminal 20 to which a store manager or the like is logged in) When the batch switching button is operated, the switching by the batch method is executed, but when the batch switching button is operated by the POS terminal 20 that is not a specific POS terminal 20, the switching is performed by the batch method. In addition, the same operation is performed by the adjustment only mode switching button (described later).

  Next, the individual switching method will be described. FIG. 22 is an explanatory diagram for explaining mode switching. In the above description, the configuration A and the configuration B have been described. However, the individual switching method described with reference to FIG. For example, the present invention is also applied to a scene where the normal mode POS terminal and the semi-self (settlement-only mode) POS terminal 20 are switched to one and the full self mode POS terminal 20 is switched to two.

  As an example of two types of operation modes (normal mode, full self mode), it has been explained that the operation mode is switched in order each time the mode switching button is operated. However, there are three or more types of operation modes. Even in this case, each time the mode switching button is operated, the mode may be switched to each operation mode in the same manner as in the case where two types of operation modes exist. When there are three or more operation modes, a plurality of operations are required when switching to the target operation mode.

  FIG. 23 is an explanatory diagram illustrating mode switching. The individual method (1) shown in Fig. 23 is an explanation of an example in which three types of operation modes (normal mode, full self mode, and semi-self (settlement-only mode) are switched in order. In the case of 1), since “normal mode” → “full self mode” → “semi self (settlement only mode)” is switched, for example, when the current operation mode is the normal mode, the mode is switched to semi self (settlement only mode). This requires two operations.

  If a plurality of mode switching operations are prepared, the number of operations is reduced when switching to the target operation mode. In the individual method (2) shown in FIG. 23, when the mode switching operation 1 (for example, the operation of the mode switching button in FIG. 3) is performed, the normal mode and the full self mode are sequentially switched, and the mode switching operation is performed. When 2 (for example, operation of the adjustment only mode switching button provided in the key operation unit 211) is performed, the mode is switched to “semi-self (adjustment only mode)”. The POS terminal 20 may switch the operation mode of each POS terminal 20 by a method based on the individual method (2) instead of the individual method (1).

  23, when the mode switching operation 1 is performed (the same applies when the mode switching operation 2 is performed), the current operation mode is “semi-self (settlement only mode)”. If there is, it may be switched to the operation mode (“normal mode” or “full self mode”) before the “semi-self (settlement only mode)”.

  Also, instead of the individual method (1) and the individual method (2), a number of mode switching buttons corresponding to each of the operation modes are prepared, and the operation mode corresponding to the operated mode switching button is switched. Good.

  The mode switching button for switching the operation mode is a hardware key, but the operation mode is switched by a software key displayed on the display unit (the store clerk side display unit 210 or the like) instead of or in addition to the hardware key. It may be. That is, a software key corresponding to the switching button may be displayed instead of or in addition to the switching button, or a software key corresponding to the batch switching button may be displayed instead of or in addition to the batch switching button. However, instead of or in addition to the adjustment only mode switching button, a software key corresponding to the adjustment only mode switching button may be displayed. The same applies to each button when the number of mode switching buttons corresponding to each of the operation modes is prepared.

[Sixth Modification]
As described above, under the example of the arrangement of the POS terminal 20 in FIG. 21, the operation mode of the POS terminal 20 on the island is changed according to the operation on the buttons (mode switching button, batch switching button, and adjustment mode switching button). It can be switched individually or in a batch.
On the other hand, the present modification is configured such that the operation mode is switched according to the state of detection of the presence of the store clerk under the arrangement example of the POS terminal 20 in FIG. Specifically, for example, the operation mode is switched as follows.
That is, under the state of the configuration B in FIG. 21B, all of the salesclerks corresponding to the POS terminals 20-1 and 20-3 in the normal mode are separated from the POS terminals 20-1 and 20-3. (For example, logged out). In response to such a situation, it is determined that both the POS terminals 20-1 and 20-3 are in a state where the presence of a store clerk is not detected. In response to such a determination, the POS terminals 20-1 and 20-3 are each switched from the normal mode to the full self mode. As a result, the POS terminal 20 transitions to the state of the configuration A in FIG.

  Further, among the clerk corresponding to each of the POS terminals 20-1 and 20-3 in the normal mode under the state of the configuration B in FIG. In the case of leaving, at the POS terminal 20 corresponding to the other clerk 2, for example, “Clerk 1 has left the registration service. When the clerk 2 leaves the registration service, all POS terminals on this island are fully self-service. For example, a message is displayed to the store clerk. By receiving such notification, the clerk 2 can grasp in advance that all four POS terminals 20 on the same island will be in the full self mode if he / she leaves the POS terminal 20.

[Seventh Modification]
Further, as this modification, the operation mode may be switched individually for each lane corresponding to the accounting lead shown in the arrangement example of the POS terminal 20 in FIG.
In other words, one of the two POS terminals 20 in which a store clerk exists is detected in a state in which it is detected that the store clerk exists in one of the two POS terminals 20 corresponding to one lane. Is set to the normal mode, and the full self mode is set to the other POS terminal 20 in which it is detected that no clerk is present. When it is detected from this state that the store clerk is away from one of the POS terminals 20 and no store clerk exists, the one POS terminal 20 is changed from the normal mode to the full self mode. At this time, the other POS terminal 20 is maintained in the full self mode because no clerk is present.
On the other hand, in the state where the full self mode is set for any of the two POS terminals 20 corresponding to one lane, a store clerk exists in one of the POS terminals 20. If it is determined, the POS terminal 20 in which the store clerk is present is switched to the normal mode. In this case, the full self mode may be continued as it is for the other POS terminal 20 because the store clerk is not present. In addition, when switching the POS terminal 20 in a state where a store clerk exists to the normal mode, a dialog for confirming whether or not the switch to the normal mode may be performed may be displayed for the store clerk. When the store clerk performs an operation for instructing the dialog to switch to the normal mode, the mode shifts to the normal mode, but when the operation for instructing not to switch to the normal mode is performed, the full operation is performed. The self mode may be maintained.
