The communication unit 215 transmits and receives information to and from other devices (other POS terminals 20 and the store controller 10).

(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. For example, the POS terminal 20 has a normal mode, a full self mode, and a semi self mode. Note that the operation modes described below are normal operation modes (operation modes related to product registration processing and accounting processing). Aggregation modes for counting and inquiring sales and stocks, etc. It does not include the maintenance mode for setting work and maintenance work, the training mode for newcomer training. The semi-self mode is an operation mode mainly used when data is transmitted / received between the plurality of POS terminals 20. Here, in order to describe an example in which the registration process and the settlement process are executed by one POS terminal, the normal mode and the full self mode will be described in detail below.

  The registration process is a process that starts when a purchased product is first registered and ends when a registration completion key is operated. The settlement process is a process that starts when the settlement start process is performed and ends when the change has been paid out. The settlement start process is an initial process for starting the settlement process, and includes, for example, selection of a payment method. For example, the payment method is selected by inserting money into the change machine 209. By inserting money into the change machine 209, cash payment is selected. As the selection of the payment method, there are payment by cash selected by depositing into the change machine 209, payment by cash, payment of various cards such as a credit card, and the like. The customer can select a preferred payment method from these payment methods. These payment methods are selected independently, but a plurality of payment methods may be selected. For example, if the total amount of purchased goods is higher than the charge balance stored in the transportation card, pay all the balance of the transportation card to payment, and pay the amount of money with cash or credit card It may be. The settlement start process can be performed after the registration process is started, but can also be performed before the registration process is started. Specifically, the payment start process is started before the registration process is started by depositing cash before the registration process is started. For this reason, the settlement process including the settlement start process may be started after the registration process is started, or may be started before the registration process is started.

5 and 6 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, accounting processing) in the normal mode and the operation of a person (store clerk, customer). FIG. 5B is a flowchart showing a basic flow of the operation of the POS terminal 20 in the normal mode.
FIG. 6 is a diagram for explaining the outline of the full self mode. FIG. 6A is a schematic diagram showing the flow of processing (product registration processing, accounting processing) and the operation of a person (customer) in the full self mode. FIG. 6B is a flowchart showing a basic flow of the operation of the POS terminal 20 in the full self mode.

  In the following description, the mode in which the POS terminal 20 executes the merchandise registration process is defined as a registration mode and a checkout as a different opening from the classification of the above three operation modes (normal mode, full self mode, and semi self mode). A mode for executing processing may be referred to as an accounting mode.

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

  In the normal mode, the store clerk registers the customer's purchased products on the store clerk side (store clerk side scanner unit 212, store clerk side display unit 210, key operation unit 211). In other words, the POS terminal 20 executes a process for registering purchased products by an operation of the store clerk (operation of the store clerk side scanner unit 212, store clerk side display unit 210, 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 subtotal key in step S30 is an operation key for completing the registration process, and may be referred to as a subtotal button, a registration completion key, a registration completion button, an accounting key, an accounting button, or the like.

  The customer may be on standby until the registration process by the store clerk is completed (until the total amount is confirmed), but before the registration process is completed, the customer may put money into the change machine 209, Payment method selection, for example, payment by the card settlement unit 208 may be selected. That is, the POS terminal 20 can deposit money as a settlement start process even before the registration process is completed, for example, before the registration process or during the pedaling process (upper part of FIG. 5A).

  In addition, the store clerk may be on standby after completing the registration of the purchased product until the customer's payment is completed (until the customer receives a change or receipt), but registers the purchased product of the next customer. Also good. 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). In other words, the customer's reception may be completed during the checkout of the customer after the registration of the purchased product is completed.

  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 control for issuing a receipt after the customer removes the change / pull is performed in the same manner in other operation modes. As described above, in the normal mode, there may be a case where a store clerk is present or not in front of a customer who receives a change. For example, when there is a store clerk, the above-described control is not necessarily performed (that is, In addition, the change / dispatch and the receipt may be issued at the same time, or the receipt may be issued first). Further, according to the current operation mode and the presence / absence of a store clerk (for example, the presence / absence of a store clerk is recognized by a sensor), the timing of paying out change / fishing bills and issuing a receipt may be controlled.

(Full self mode)
As shown in FIG. 6A, the full self mode is an operation mode in which registration processing is executed on the customer side and settlement processing is executed on the customer side. That is, as shown in FIG. 6B, in the full self mode, the customer side is in the registration mode and the accounting mode. That is, the POS terminal 20 operates as a registration accounting mode when viewed through the registration process to the settlement process.

  In the full self mode, the customer registers the purchased product on the customer side (customer side scanner unit 206, customer side display unit 205). In other words, the POS terminal 20 performs a purchase product registration process by a customer operation or the like (scanning by the customer side scanner unit 206, touching the customer side display unit 205) (upper part of FIG. 6A).

  When the registration process is completed, the customer confirms the total amount of the purchased product on the customer side display unit 205, inserts money into the change machine 209, or operates the card settlement unit 208 to settle it (FIG. 6 (A ) Bottom). That is, the POS terminal 20 executes the settlement process by the customer's operation or the like (insertion of money into the change machine 209, operation of the card settlement unit 208) (lower part of FIG. 6A).

  That is, in the full self mode, as shown in FIG. 6 (B), on the customer side, for example, the customer side scan unit 206 scans the product (step S20: YES) and registers the product (step S21). After pressing a registration completion key (for example, the end (receipt) button BT40 displayed on the customer side display unit 205 shown in FIG. 11B) (step S40: YES), on the customer side, for example, by the change machine 209 Checkout is performed (step S50), and the process is completed. Note that the registration completion key according to step S40 is an operation key for completing the registration process, and may be referred to as a registration completion button, a subtotal key, a subtotal button, an accounting key, an accounting button, or the like.

  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, for example, the pressing operation of the first mode switching button BT12 displayed on the clerk side display unit 210 shown in FIG. Is possible. In the full self mode, before starting the registration, as shown in FIG. 13B, the second mode switching button BT13 is displayed with the words “switch to face-to-face self”. When the customer registers the purchased product in the full self mode, as shown in FIG. 14B, the second mode switching button BT13 is displayed with the characters “join registration”. When the mode switching button BT13 is pressed, registration of purchased products by the store clerk side scanner unit 212 becomes possible. A state (operation mode) in which registration processing is executed on both the clerk side and the customer side may be referred to as a double scan mode.

  In the full self mode, payment start processing such as payment to the change machine 209 cannot be performed before the product registration processing is started, but the payment start processing is performed before the product registration processing is started. You may be able to do that. In this case, in the full self mode, it may be possible to perform all processes of the settlement start process such as payment and selection of payment method by various cards, or a part of the settlement start process, for example, deposit of money Alternatively, only the payment method may be selected. In the full self mode, when it is possible to select a payment method using various cards as the settlement start process so that the settlement start process can be performed before the registration process, the registration start shown in FIG. On the screen, buttons corresponding to various cards to be paid may be displayed, or buttons for specifying a screen for selecting a payment method may be displayed.

(Notification of operation mode)
The POS terminal 20 notifies the current operation mode. For example, the current operation mode may be displayed on the clerk side display unit 210. Specifically, a screen having an operation mode display field may be displayed on the clerk-side display unit 210, and the current operation mode may be displayed in the operation mode display field on the screen. In addition, a screen on which images corresponding to each operation mode (for example, a button-like image) are arranged is displayed on the clerk-side display unit 210, and an image corresponding to the current operation mode is displayed on the screen. You may display in the display mode (For example, the display mode conspicuous rather than the display mode of another image) different from the image which does not respond | correspond. The operation mode may be displayed on the customer display unit 205 in the same manner.

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

(Operation mode transition)
Next, the transition (switching) of the operation mode of the POS terminal 20 will be described. The operation mode of the POS terminal 20 is shifted according to an explicit mode switching operation (mode switching operation) by a store clerk. Specifically, the key operation unit 211 includes a plurality of buttons. According to the operation of the mode switching button 211a (see FIG. 3B) arranged at the uppermost and rightmost among these buttons. The operation mode shifts.

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

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

  In the present embodiment, the mode switching button 211a is arranged at the upper right corner of the key operation unit 211. However, if the position can be recognized only by groping (a position that can be recognized relatively easily), the mode is switched. The switching button 211a may be disposed at a position other than the upper right corner of the key operation unit 211, for example, at the lower right corner. Further, instead of or in addition to arranging the mode switching button 211a at a position that can be recognized only by groping (for example, at the upper right corner), it can be distinguished from other buttons even from the customer side. Alternatively, a mode switching button 211a may be formed. For example, the size of the mode switching button 211a may be different from the size of other buttons so that the mode switching button 211a can be distinguished only by groping, or the shape of the mode switching button 211a may be different from the shape of other buttons. Alternatively, the height of the mode switching button 211a may be different from the height of the other buttons (for example, the mode switching button 211a may protrude more than the other buttons). ) The touch of the entire surface (the surface touched by the hand) of the mode switching button 211a may be different from the touch of the other buttons (for example, only the surface of the mode switching button 211a is rough or rough) You may make it feel, or you may make it provide a protrusion and a hollow only in the surface of the mode switching button 211a).

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

  Next, the transition (switching) of the operation mode of the POS terminal 20 will be described. The POS terminal 20 uses an explicit mode transition operation by the store clerk (for example, as shown in FIG. 9A, the first mode switch button BT12 or the second mode switch button BT13 displayed on the store clerk side display unit 210 is pressed. The operation mode shifts according to operation, input on the operation mode setting screen, operation mode operation button operation, and the like. As a button (key) used for mode switching, the key operation unit 211 is used instead of the first mode switching button BT12 shown in FIG. 9A or the like or the second mode switching button BT13 shown in FIG. 13B. The mode switching key (hard key) set in the above may be used, or these may be used in combination. As shown in FIG. 9A, the characters “switch to full self” are displayed on the first mode switching button BT12 displayed in the normal mode. Hereinafter, a transition example in the case where the operation mode is shifted by pressing the first mode switching button BT12 will be described.

  7 and 8 are diagrams illustrating an example of operation mode transition. FIG. 7 is a flowchart showing a flow of transition from the normal mode to the full self mode. FIG. 8 is a flowchart showing a flow of transition from the full self mode to the normal mode. The transition from the normal mode to the full self mode and the transition from the full self mode to the normal mode are performed by, for example, the first mode switching button BT12 or the second mode switching button BT13 by a store clerk when the product is not registered. Done by operation. In addition, when a condition such as the start of the registration process is established, there is a case where the transition of the operation mode by the operation of the first mode switching button BT12 or the second mode switching button BT13 is prohibited. Further, in the full self mode, when processing such as registration processing on the customer side is not performed for a certain period of time, registration by the customer scanner unit 206 or the like is prohibited (for example, usage status of the customer scanner unit 206 being accepted) May be lifted). Hereinafter, these cases will also be described.

(Transition from normal mode to full self mode)
The flowchart of FIG. 7 starts at all times (periodically at very short time intervals) in the POS terminal 20 (normal mode). Since it is in the normal mode, the clerk side scanner unit 212 is being accepted and the customer side scanner unit 206 is not being accepted. When the clerk side scanner unit 212 is accepting, the product can be registered by pressing the clerk side display unit 210. Similarly, when the clerk side scanner unit 212 is not accepting, registration of products by pressing the clerk side display unit 210 is impossible. Similarly, when the customer side scanner unit 206 is accepting, it is possible to register a product by pressing the customer side display unit 205, and when the customer side scanner unit 206 is not accepting. The product registration by the pressing operation of the customer side display unit 205 is impossible. The reception in the customer side scanner unit 206 and the store clerk side scanner unit 212 refers to reading of purchased products and the like, and can be read during reception, but cannot be read during non-reception. The reception of the customer side scanner unit 206 and the store clerk side scanner unit 212 means the usage state of the customer side scanner unit 206 and the store clerk side scanner unit 212. In other words, it is in an available state when it is being received and is not being received. It is in an unusable state. The unreadable state may be a state in which the functions of the customer side scanner unit 206 and the store clerk side scanner unit 212 are stopped, or the customer side scanner unit 206 and the store clerk side scanner unit 212 themselves are functioning. The information read by the side scanner unit 206 and the store clerk side scanner unit 212 may be processed so that the CPU 201 does not recognize the information.

  Further, in the flowcharts shown in FIGS. 7 and 8, scanning in the customer side scanner unit 206 and the clerk side scanner unit 212 may mean only scanning in the customer side scanner unit 206 and clerk side scanner unit 212, Other merchandise registration methods may be included. For example, scanning in the customer-side scanner unit 206 includes an operation in which a customer presses an order button to register a product when a product order button (preset key) or the like is displayed on the customer-side display unit 205. But you can. The scanning in the customer-side scanner unit 206 includes an operation in which the store clerk presses the order button to register the product when a product order button (preset key) or the like is displayed on the store-side display unit 210. Alternatively, when a key corresponding to a product (for example, a key corresponding to a sports newspaper) is arranged in the key operation unit 211, the store clerk performs an operation of pressing the key to register the product. May be included. In addition, when the customer-side scanner unit 206 is not accepting, the customer-side display unit 205 may not display the product order button (preset key) or the like, and the order button is displayed. However, registration may not be performed even if an operation of pressing the order button is performed. Similarly, when the clerk side scanner unit 212 is not accepting, the order button (preset key) of the product may not be displayed on the clerk side display unit 210, and the order button is displayed. However, registration may not be performed even if an operation of pressing the order button is performed. Further, registration may not be performed even if a key corresponding to a product in the key operation unit 211 is pressed.

Step S111: It is determined whether or not there is a deposit. Depositing is performed when a customer or the like inserts banknotes or coins into the change machine 209. If there is a deposit, the process proceeds to step S112, and if there is no deposit, the process proceeds to step S113.
Step S112: A deposit process is performed. As the depositing process, the deposited amount is stored in the RAM 203, and the deposited amount is displayed on the customer side display unit 205 and the clerk side display unit 210, respectively. In addition, the settlement start process is performed by the deposit process, and the settlement process starts. Thereafter, the process proceeds to step S113.

Step S113: It is determined whether or not the mode switching button has been pressed. For example, it is determined whether or not the first mode switching button BT12 shown in FIG. If the first mode switching button BT12 is pressed, the process proceeds to step S114. If the first mode switching button BT12 has not been pressed, the process proceeds to step S115.
Step S114: It is determined whether or not registration of the purchased product is started, or whether there is a deposit process and it is before settlement. The purchased product is registered, for example, by reading a bar code (product code or the like) provided on the product by the store clerk side scanner unit 212 or the customer side scanner unit 206. Here, the customer-side scanner unit 206 is receiving, but the clerk-side scanner unit 212 is not receiving. When the clerk side scanner unit 212 is not accepting, the registration process is performed by the customer side scanner unit 206. If registration of the purchased product is started or there is a deposit process and it is before settlement, the process proceeds to step S115. In step S114, when the first mode switching button BT12 is operated, a process for shifting from the normal mode to the full self mode is performed, but after the registration process or the deposit process, the first process is performed. Even if the mode switching button BT12 is operated, the transition from the normal mode to the full self mode is prohibited, and the switching of the store clerk side scanner unit 212 and the customer side scanner unit 206 is prohibited. For this reason, if the registration of the product has not been started and no deposit process has been performed, or after settlement, the process proceeds to step S119.

Step S115: It is determined whether or not the salesclerk side scanner unit 212 has scanned the product. Whether or not the clerk side scanner unit 212 has scanned the product is determined by whether or not the clerk side scanner unit 212 has scanned the barcode attached to the purchased product. If the salesclerk side scanner unit 212 scans the purchased product, the process proceeds to step S116. If the clerk-side scanner unit 212 has not scanned the purchased product, the process proceeds to step S117.
Step S116: The purchased product is registered in the RAM 203. Specifically, various information such as product information in the barcode scanned by the store clerk side scanner unit 212 is stored in the RAM 203. Thereafter, the process proceeds to step S117.

Step S117: It is determined whether or not an accounting button (subtotal key) has been pressed. For example, it is determined whether or not the end (receipt) button BT40 shown in FIG. If the accounting button is pressed, the process proceeds to step S118. If the accounting button has not been pressed, the process returns to step S111.
Step S118: A settlement process is performed. After the settlement process is completed, a receipt is issued by the printing unit 213, for example. Then, the flowchart of FIG. 7 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.

Step S119: The operation mode is shifted from the normal mode to the full self mode (registration only mode). Thereafter, the process proceeds to step S120.
Step S120: Reception of the customer side scanner unit is started. In the full self mode, since the customer-side scanner unit 206 performs registration of purchased products, the customer-side scanner unit 206 that has not been received is set to be receiving. Thereafter, the process proceeds to step S121.
Step S121: Reception of the clerk side scanner unit 212 is stopped. In the full self mode, since the clerk-side scanner unit 212 registers the purchased product, the clerk-side scanner unit 212 that has been receiving is not accepted. Then, the flowchart of FIG. 7 ends.

  In this way, in the normal mode, the transition to the full self mode is allowed until there is registration or payment of purchased products (after the settlement is completed if there was a process from registration to settlement in the previous time). The usage state of the customer side scanner unit 206 and the store clerk side scanner unit 212 can be switched. Further, after the purchased product is registered or deposited, the transition to the full self mode is prohibited until the checkout is completed, and switching of the usage state of the customer side scanner unit 206 and the store clerk side scanner unit 212 is prohibited. .

(Transition from full self mode to normal mode)
The flowchart of FIG. 8 starts at all times (periodically at very short time intervals) in the POS terminal 20 (full self mode). Since it is in the full self mode, the clerk side scanner unit 212 is not accepted, and the customer side scanner unit 206 is being accepted. Further, a forced end button described later is not accepted.

Step S151: It is determined whether or not there is an operation on the customer side. The customer side operations include, for example, scanning by the customer side scanner unit 206 and operations of various buttons displayed on the customer side display unit 205. If there is an operation on the customer side, the process proceeds to step S152. The time when the customer's operation is last (when the customer performs the last operation) is the time measurement start condition for starting the time measurement by the time timer. If there is no operation on the customer side, the process proceeds to step S154.

Step S152: A time timer is set. The timekeeping timer is a timer that measures the time during which various customer-side devices are not operated. A time limit is set in the timer. The time limit is a time for shifting the operation mode to the face-to-face mode when various devices on the customer side are not operated in the full self mode, and can be set to any time. The time can be 10 minutes. Moreover, it is good also as time other than these time. Further, the time limit may be arbitrarily set at a store or the like. The time measured from the last operation on the customer-side scanner unit 206 or the customer-side display unit 205 is measured by the timer.
Step S153: The forced termination button shown in FIG. 14B and FIG. Here, when the forced end button is being accepted, the forced end button is changed to not accepted, and when the forced end button is not accepted, the state is maintained.

Step S154: It is determined whether or not the mode switching button has been pressed. For example, it is determined whether or not the second mode switching button BT13 shown in FIG. If the second mode switching button BT13 is pressed, the process proceeds to step S155. If the second mode switching button BT13 has not been pressed, the process proceeds to step S158.
Step S155: It is determined whether or not it is after the registration of the purchased product is started and before the settlement. If it is after the registration of the purchased product is started and before the settlement, the process proceeds to step S156. In step S155, when the second mode switching button BT13 is operated, a process for shifting from the full self mode to the normal mode is performed. However, after the registration process is performed, the second mode switching is performed. Even when the button BT13 is operated, the transition from the full self mode to the normal mode is prohibited. As described above, when there is a registration process or the like, switching of usage states of the clerk side scanner unit 212 and the customer side scanner unit 206 is prohibited. For this reason, if the registration of the product has not started, the process proceeds to step 167.

Step S156: It is determined whether or not the clerk side scanner unit 212 is accepting. The clerk side scanner unit 212 is not accepted at the start of the flowchart shown in FIG. 8, but may be switched to being accepted in a later process. If the clerk side scanner unit 212 is not accepting, the process proceeds to step S157. If the clerk side scanner unit 212 is accepting, the process proceeds to step S158.
Step S157: Reception of the clerk side scanner unit 212 is started. Specifically, the clerk side scanner unit 212 is switched from being not accepted to being accepted. When the clerk-side scanner unit 212 is switched during reception, the product shifts to a double scan mode in which both the customer-side scanner unit 206 and the clerk-side scanner unit 212 can register purchased products. In the normal mode, when the registration process is started, even if the second mode switching button BT13 is operated, in step S114 in FIG. 7, the customer-side scanner unit 206 is prohibited from being switched during reception. In the full self mode, when the second mode switching button BT13 is operated after registration is started, the prohibition of switching from non-acceptance to acceptance is canceled by the clerk side scanner unit 212, and the clerk side scanner unit 212 is released. Starts accepting. Thereafter, the process proceeds to step S155.

Step S158: It is determined whether or not the customer-side scanner unit 206 has scanned the product. Whether the customer-side scanner unit 206 has scanned the product is determined by whether the customer-side scanner unit 206 has scanned the barcode attached to the purchased product. If the customer-side scanner unit 206 scans the purchased product, the process proceeds to step S159. If the customer-side scanner unit 206 has not scanned the purchased product, the process proceeds to step S161.
Step S159: It is determined whether or not the clerk side scanner unit 212 is accepting. If the clerk side scanner unit 212 is accepting, the process proceeds to step S160. If the clerk side scanner unit 212 is not accepting, the process proceeds to step S163.

Step S160: It is determined whether or not the merchandise has been scanned by the clerk side scanner unit 212. If the salesclerk-side scanner unit 212 scans the purchased product, the process proceeds to step S161. If the clerk-side scanner unit 212 has not scanned the purchased product, the process proceeds to step S163.

Step S161: The purchased product is registered in the RAM 203. Specifically, various information such as product information in the barcode scanned by the store clerk side scanner unit 212 or the customer side scanner unit 206 is stored in the RAM 203.
Step S162: It is determined whether or not an accounting button has been pressed. For example, it is determined whether or not an accounting button (end (receipt) button BT40 shown in FIG. 14A) is pressed. If the accounting button is pressed, the process proceeds to step S170. If the accounting button has not been pressed, the process returns to step S151.

Step S163: It is determined whether or not the time limit has elapsed. Specifically, it is determined whether or not the time set in the clock timer has elapsed in step S152. If the time limit has elapsed, the process proceeds to step S164. If the time limit has not elapsed, the process proceeds to step S162.
Step S164: Start accepting the forced end button. For example, as shown in FIG. 15, below the clerk side display unit 210 in the full self mode, a forced end button BT14 for forcibly ending the full self mode and shifting to the normal mode and the full self mode to the double scan mode. A clerk participation button BT15 for switching is displayed. The forced end button BT14 and the store clerk participation button BT15 are displayed side by side at the center lower position of the store clerk side display unit 210. When the forced end button BT14 starts accepting, the clerk or the like presses and operates the forced end button BT14 to forcibly end the full self mode and shift to the normal mode. Note that before the acceptance of the forced end button is started, the forced end button BT14 is displayed in gray down as shown in FIG. 14B. At this time, instead of displaying the forced end button BT14 grayed out, the forced end button BT14 may not be displayed. When the forcible end button BT14 is pressed, the registration is forcibly terminated and registration by the operation of the customer side scanner unit 206 cannot be performed. For this reason, by starting reception of the forced end button, switching from reception to non-reception of the customer-side scanner unit 206 is cancelled.
Step S165: It is determined whether or not the forced end button has been pressed. Specifically, it is determined whether or not the forced end button BT14 shown in FIG. 15 is pressed and operated by a store clerk or the like. If the forced end button is pressed, the process proceeds to step S166. If the forced end button has not been pressed, the process proceeds to step S162.
Step S166: The full self mode is terminated. After exiting the full self mode, the mode shifts to the normal mode. When the forced termination is performed, the registration information and the like of the registered and unsettled product is discarded (erased). Then, the flowchart of FIG. 8 ends. Note that after the forced termination, the full self mode may be maintained, the operation mode may be shifted to a mode other than the normal mode, or the operation mode to be shifted may be designated. Further, the registration information may not be discarded after the forced termination.

Step S167: The operation mode is shifted from the full self mode (registration only mode) to the normal mode.
Step S168: Reception of the clerk side scanner unit is started. In the normal mode, since the clerk-side scanner unit 212 registers the purchased product, the clerk-side scanner unit 212 that has not been accepted is being accepted.
Step S169: Reception of the customer side scanner unit 206 is canceled. In the normal mode, since the sales clerk side scanner unit 212 performs registration of purchased products, the customer side scanner unit 206 that has been receiving is set to non-accepting. Then, the flowchart of FIG. 8 ends.
Step S170: A settlement process is performed. After the checkout process is completed, for example, a receipt is issued by the printing unit 213, for example. Then, the flowchart of FIG. 8 ends.

  As described above, in the full self mode, the transition to the normal mode is permitted until the purchased product is registered or received, and the usage state of the customer side scanner unit 206 and the store clerk side scanner unit 212 can be switched. In addition, after the purchase merchandise is registered or deposited, the transition to the full self mode is prohibited until the settlement is completed, but instead the transition to the double scan mode is performed. For this reason, switching of the usage state of the customer side scanner unit 206 and the store clerk side scanner unit 212 is prohibited until the payment is completed after the purchase product is registered or deposited, Will be lifted.

  In addition, when the full self mode is started, since the customer registers the product, switching of the usage state of the customer side scanner unit 206 is prohibited, but a long time has passed without the customer side operation being performed. Then, it is conceivable that the customer canceled the registration by the customer side scanner unit 206 halfway before the settlement was completed. For this reason, when the time limit has elapsed without any operation on the customer side, the switching of the usage state of the customer side scanner unit 206 is canceled and the customer side scanner unit is shifted from the full self mode to the normal mode. 206 is not accepted.

  In the full self mode, when the deposit process is enabled before the registration process is started as in the normal mode, the timing at which the second mode switching button BT13 is pressed in step S152 after the registration starts. Instead of determining whether to switch from the full self mode to the normal mode if it is not before settlement, transition to the normal mode from the full self mode when the timing when the second mode switching button BT13 is pressed is not before the start of registration or after settlement. You may make it do. Further, in the steps shown in FIG. 7 and FIG. 8, the example in which the settlement start process is the deposit to the change machine 209 has been described. However, when another change settlement start process is performed, the change machine 209 receives the deposit. The same processing may be performed.

(Display during normal mode)
Next, display during the normal mode will be described with reference to FIGS. 9 to 12 are display examples of the clerk side display unit 210 and the customer side display unit 205 in the normal mode. FIG. 9A is a display example of a registration screen displayed on the clerk-side display unit 210 of the POS terminal 20, and is a display example of a registration start screen before a product is purchased. In the screen shown in FIG. 9A, a subtotal button BT10, a pause button BT11, and a first mode switching button BT12 are displayed at the lower right of the screen. The subtotal button BT10 is a button (registration completion key) for instructing the end of product registration. The store clerk performs an operation (touch) of pressing the subtotal button BT10 after the product registration is completed. The pause button BT11 is a button for pausing the POS terminal 20. The store clerk operates the pause button BT11 when leaving the POS terminal 20 (for example, when searching for a product or not using the POS terminal 20 for a while). The first mode switching button BT12 is a button for switching modes. The store clerk operates the first mode switching button BT12 when switching modes. On the first mode switching button BT12, characters “switch to full self” are displayed. The first mode switching button BT12 is displayed grayed out when mode switching is prohibited and the operation of the button is not valid. Instead of gray-down display, no display may be performed. Moreover, since it is difficult to consider the opportunity to operate the subtotal button BT10 until the product is registered, the subtotal button BT10 may not be displayed on the registration start screen. In this case, for example, the subtotal button BT10 may be displayed when a product is registered at the beginning of the transaction.

  FIG. 9B is a display example of a screen displayed on the customer-side display unit 205 of the POS terminal 20 and is a display example before a product is purchased. In the screen shown in FIG. 9B, a salesclerk call button BT33 is displayed on the lower left side, and display language switching buttons BT35 to B37 are displayed on the right side. The salesclerk call button BT33 is a button for calling a salesclerk. The customer operates the store clerk call button BT33 when calling the store clerk (for example, when the store clerk needs support). Display language switching buttons BT35 to BT37 are buttons for switching the display language to English, Chinese, and Korean, respectively. On the display language switching buttons BT35 to BT37, the national flag of each country and characters indicating the language are displayed in each language.

  In the message display area at the bottom of the screen, a message “You can put money at any time” is displayed, and in the center of the screen, an image simulating the state of putting money into the change machine 209 is displayed. When money is inserted into the change machine 209, the screen shown in FIG. 10 (B) is displayed on the customer's side where information on the registered product, the number of registered products associated with the registration of the product, the price, etc. are not displayed. Displayed on the part 205.

  FIG. 10A is a display example of a registration screen displayed on the clerk-side display unit 210 of the POS terminal 20 and is a display example in the middle of product registration. Specifically, FIG. 10A is a screen showing the display content of a registration screen in a scene where one item of product (canned beer) and two items of product (aspara) are registered. In the screen shown in FIG. 10 (A), the product name (aspara) of the currently registered product is displayed at the upper left of the screen, and the product names (canned beer, asparagus) of the registered product are displayed together with the respective amounts. In the upper right of the screen, the number of registered products and the total amount are displayed. Since the switching of the operation mode is prohibited when the registration of the product is started, the first mode switching button BT12 is displayed in gray down. Note that the broken line of the first mode switching button BT12 indicates that the operation of the button (first mode switching button BT12) is displayed in a display mode (in this case, gray down). Further, the display may not be performed in place of the gray-down display.

  FIG. 10B is a display example of a screen displayed on the customer-side display unit 205 of the POS terminal 20, which is a display example in the middle of product registration, and is shown in FIG. 10A. It is a screen displayed on the customer side display unit 205 when the image is displayed on the store clerk side display unit 210. In the screen shown in FIG. 10 (B), the product name of the registered product (canned beer, asparagus) is displayed on the upper side, and the product name (asparagus) of the currently registered product is displayed on the lower left side along with the respective registration score and amount. ing. Below that, the number and the total amount of the registered products and the deposit amount are displayed. The deposit amount is the amount of money that has been inserted from the change machine 209. In the screen shown in FIG. 10B, a store clerk call button BT33 is displayed on the right side, and display language switching buttons BT35 to B37 are displayed on the lower side. The functions of the salesclerk call button BT33 and the display language switching buttons BT35 to B37 are the same as those of the buttons shown in FIG.

  FIG. 11A is a display example of a screen displayed on the clerk-side display unit 210 of the POS terminal 20, and is a display example in the middle of settlement. Specifically, FIG. 10A shows that when the registration screen is displayed, the total amount is “total” on the screen where the product is registered last, and for the change machine 209. It is a screen in which the deposit amount is displayed as “amount of money for fishing machine”. In the example shown in FIG. 11A, “383 yen” is displayed as the total amount, and “1,000 yen” is displayed as the fishing machine deposit amount.

  In addition, a deposit cancellation button BT18 is provided at the lower right of the change machine deposit amount. The deposit cancellation button BT18 is a button for canceling the deposit to the change machine 209. A store clerk who receives a request for deposit cancellation cancels the deposit by pressing a deposit cancellation button BT18. When the deposit is cancelled, money corresponding to the deposited amount is refunded from the change machine 209 to the customer. The money to be paid back may be the money itself inserted by the customer, or may be the money equivalent to the money inserted by the customer. The deposit cancellation button BT18 is displayed on the clerk side display unit 210 and is not displayed on the customer side display unit 205. For this reason, when the customer cannot perform the operation of canceling the deposit and wants to return the deposited money, he / she asks the store clerk. The deposit cancellation button BT18 may be displayed not only on the clerk side display unit 210 but also on the customer side display unit 205, or may be displayed only on the customer side display unit 205.

  When the screen shown in FIG. 11A is displayed, switching of the operation mode (switching from the normal mode to the full self mode) is prohibited, so the first mode switching button BT12 shown in FIG. 9A. Is not displayed. On the other hand, the gray-down first mode switching button BT12 may be displayed.

  FIG. 11B is a display example on the settlement screen displayed on the customer side display unit 205 of the POS terminal 20. Specifically, on the screen shown in FIG. 11B, a message “Please press the end button if you like” is displayed, as well as the payment amount (here, “383 yen”), Here, “1,000 yen”) and a change (here “617 yen”) are displayed. The payment amount is the total amount of the registered product. The deposit amount is the total amount of money that the customer has put into the change machine 209. The change is the amount obtained by subtracting the payment amount from the deposit amount. An end (receipt) button BT40 is displayed below the column in which the change is displayed. The end (receipt) button BT40 is displayed when the deposit amount is equal to or greater than the payment amount. When the end (receipt) button BT40 is pressed, the deposit amount and the payment amount are confirmed and the payment is executed, and change (here, “617 yen”) is discharged from the change machine 209.

  FIG. 12A shows a settlement screen (change screen) displayed when changing is released. For example, the POS terminal 20 displays a change screen as shown in FIG. 12A when the end (receipt) button BT40 is operated. Displaying the change screen shown in FIG. 12A prompts the customer to remove the change. FIG. 12B is a payment screen (receipt screen) displayed when the change is removed. For example, in the POS terminal 20, when change is removed from the outlet of the change machine 209, a receipt screen as shown in FIG. 12B is displayed, and a receipt or the like is issued by the printing unit 213. Note that the POS terminal 20 may determine that the change has been removed when a sensor such as a photosensor is installed in the vicinity of the outlet, and the sensor recognizes an object (assuming a customer's hand).

(Display during full self mode)
Next, display during the full self mode will be described with reference to FIGS. 13 and 14 are display examples of the customer side display unit 205 and the clerk side display unit 210 during the full self mode, and FIG. 15 is a display example of the clerk side display unit 210 during the full self mode. FIG. 13A is a display example of a registration start screen displayed on the customer-side display unit 205 of the POS terminal 20 before starting product registration. In the screen shown in FIG. 13A, a registration start button BT30 is displayed on the right side of the screen, and display language switching buttons BT35 to BT37 are displayed on the lower left side of the screen. The registration start button BT30 is a button for instructing the start of product registration. The customer operates the registration start button BT30 before starting the product registration.

  FIG. 13B is a display example of a registration start screen displayed on the clerk side display unit 210 of the POS terminal 20 before the product registration is started. In the screen shown in FIG. 13B, in addition to the screen shown in FIG. 13A, a second mode switching button BT13 is displayed. In the screen shown in FIG. 13B, a registration start button BT30 and display language switching buttons BT35 to BT37 are displayed, but these buttons cannot be operated. Inoperable means that the button does not react even when pressed, or the button reacts when pressed, but the predetermined function is not exhibited even if the button reacts. For example, when the registration start button BT30 displayed on the store clerk side display unit 210 is pressed, the registration start button BT30 does not react or the product registration is not started even if it reacts.

  On the second mode switching button BT13, characters “Switch to face-to-face self” are displayed. The second mode switching button BT13 has a function of switching the operation mode, similar to the first mode switching button BT12 displayed in FIG. When the store clerk presses the second mode switching button BT13 before the product registration is started, the operation mode shifts from the full self mode to the normal mode. Note that when mode switching is prohibited and the operation of the button is not valid, the second mode switching button BT13 is not displayed. At this time, the second mode switching button BT13 may be displayed in gray down.

  FIG. 14A is a display example of a registration screen displayed on the customer side display unit 205 of the POS terminal 20 before the product registration is started. Specifically, FIG. 14 (A) shows the display content of the registration screen in a scene where two items of goods (Daifukuen) are registered. When the registration start button BT30 is operated on the registration start screen shown in FIG. 13A, a registration screen (initial registration screen) in which no product has been registered yet is displayed. For convenience of explanation, FIG. 14A shows a registration screen after the product has already been registered.

  As shown in FIG. 14A, a message “Please register the product” is displayed at the upper left of the screen, and a message “Please register with the product barcode closer to the scanner” below it. Is displayed. Further below that, a message “If there is no barcode, please select an item from below” is displayed, and below that, a “vegetable” button BT38 is displayed.

  A closing (receipt) button BT40 is displayed at the lower right of the screen, and a store clerk calling button BT33 is provided on the left side thereof. The end (receipt) button BT40 is a button for instructing the end of product registration. The customer operates the end (receipt) button BT40 after the product registration is completed. The salesclerk call button BT33 is a button for calling a salesclerk as described above.

  In addition, display language switching buttons BT35 to BT37 are displayed at the lower left of the screen. The “vegetable” button BT38 is a button for displaying each preset key of vegetables. By pressing the “vegetable” button BT38, preset keys corresponding to vegetable products (for example, carrots, Chinese cabbage, cabbage, onions, etc.) are displayed.

  FIG. 14B is a display example of a registration screen displayed on the clerk side display unit 210 of the POS terminal 20 after the product registration is started. In the screen shown in FIG. 14B, in addition to the screen shown in FIG. 14A, a second mode switching button BT13 is displayed. The registration start button BT30 and display language switching buttons BT35 to BT37 displayed on this screen are disabled in the same manner as the registration start button BT30 and display language switching buttons BT35 to BT37 shown in FIG. Further, when the clerk presses the second mode switching button BT13 after the product registration is started, the full self mode is shifted to the double scan mode. For this reason, the characters “join registration” are displayed on the second mode switching button BT13. In other words, this means that when a customer registers a product in the full self mode, the store shifts to a double scan mode in which the clerk participates in the registration. As for the second mode switching button BT13, “switch to face-to-face self” is displayed for switching from the full self mode to the normal mode before the registration or settlement is started, and after the registration or settlement is started, full self mode is displayed. “Join registration” is displayed to switch from mode to double scan mode. On the other hand, a mode switching button for switching from the full self mode to the normal mode and a mode switching button for switching from the full self mode to the double scan mode may be provided separately. In this case, these mode switching buttons are arranged at different positions on the clerk side display unit 210. Further, when these mode switching buttons are not accepted, they may be grayed out or may not be displayed.

  The screen shown in FIG. 14B is a display example before the acceptance of the forced end button is started. For this reason, since the acceptance of the forced end button has not started, the forced end button BT14 is displayed in gray down. At this time, the forced end button BT14 may not be displayed.

  FIG. 15 is a display example of a screen displayed on the clerk-side display unit 210 of the POS terminal 20, and is a display example before registration of a forced end button is started after registration of a product by a customer is started. . On the screen shown in FIG. 15, the forced end button BT14 displayed in gray down in FIG. 14B is displayed and can be pressed. By depressing the forced end button BT14 when the forced end button BT14 is displayed, the full self mode is forcibly terminated and the operation mode shifts to the normal mode.

(Display during double scan mode)
When the full self mode is shifted to the double scan mode, the screen displayed on the customer display unit 205 is the same as the screen displayed in the full self mode. In addition to the products registered by the side scanner unit 206, the products registered by the store clerk using the store clerk side scanner unit 212 are also included. At this time, the product registered by the clerk side scanner unit 212 is displayed in a different display mode from the product registered by the customer side scanner unit 206. The different display modes are modes in which, for example, the font changes or the background color is different.

  In addition, the store clerk side display unit 210 has the same screen as that displayed in the normal mode, but as a product to be registered, in addition to the product registered by the store clerk side scanner unit 212, the customer can visit the customer side. Products registered by the scanner unit 206 are also included. Moreover, at the time of payment, both the customer side display unit 205 and the store clerk side display unit 210 are common to the screen displayed in the normal mode. At this time, the product registered by the customer side scanner unit 206 is displayed in a display mode different from the product registered by the store clerk side scanner unit 212.

  When the end (receipt) button BT40 is pressed, a change screen as shown in FIG. 12A is displayed. Displaying the change screen shown in FIG. 12A prompts the customer to remove the change. FIG. 12B is a payment screen (receipt screen) displayed when the change is removed. For example, the POS terminal 20 displays a receipt screen as shown in FIG. 12B when the change is removed from the outlet of the change machine 209. Note that the POS terminal 20 may determine that the change has been removed when a sensor such as a photosensor is installed in the vicinity of the outlet, and the sensor recognizes an object (assuming a customer's hand).

  For example, in the normal mode or the full self mode, it is difficult to think of a situation where the product is switched to the full self mode or the normal mode after registration of the purchased product is started. It is considered that the operation for switching the operation mode in such a situation is not an intentional operation but is likely to be an erroneous operation. In this regard, according to the POS terminal 20 described above, after the purchase product registration is started, mode switching is prohibited. Specifically, switching from the normal mode to the full self mode and from the full self mode to the normal mode are prohibited. Switching to is prohibited. For this reason, unintended switching of the operation mode can be prevented.

  Further, for example, when the operation mode is switched between the normal mode and the full self mode after the registration of the purchased product is started, it may be necessary to re-register the purchased product from the beginning. In this case, the number of registrations of purchased products increases, the cash register operation decreases, and it takes time to settle the products, which may cause customers to wait.

  In this regard, since the POS terminal 20 prohibits mode switching after registration of purchased products is started, switching of the usage state of the clerk-side scanner unit 212 (switching between accepting and not accepting) Is prohibited. Therefore, it is possible to prevent re-registration of the purchased product, so that the product can be settled smoothly. As a result, it is possible to prevent the customer from waiting because the cash register operation can be prevented from decreasing.

  Further, in the case of the full self mode, when the customer is not used to registering the product and the product registration takes time compared to other customers, the plurality of POS terminals 20 are provided. However, the time required for processing from registration to settlement at the POS terminal 20 becomes long, and there is a concern that the operation of the POS system 1 as a whole may be reduced. In this regard, in the POS terminal 20 described above, when the customer is registering in the full self mode, the prohibition of the switching of the operation mode and the prohibition of the switching of the usage state of the clerk-side scanner unit 212 are released. By operating the second mode switching button BT13, the operation mode is switched from the full self mode to the double scan mode, and the clerk side scanner unit 212 is switched from the non-accepting state to the accepting state to start accepting the clerk side scanner unit 212. can do. Therefore, the registration time in the POS terminal 20 can be shortened, and the time taken from registration to settlement can be made equal to or longer than that of other POS terminals 20. Therefore, it is possible to prevent a decrease in the operation of the cash register, thereby preventing the customer from waiting.

  In addition, during the full self mode, when an operation on the customer side at the POS terminal 20 is not executed, it is assumed that there is no customer in the vicinity of the POS terminal 20. A possible reason for the absence of a customer in the vicinity of the POS terminal 20 is that the customer interrupted (stopped) registration of the product and left it as it was. If there is no customer near the POS terminal 20 and the full self mode is in effect, the POS terminal 20 cannot be used, causing a reduction in the operation of the POS terminal 20. In this regard, in the POS terminal 20, when a predetermined time limit has elapsed since the last operation of the customer such as a scan for the customer side scanner unit 206 or an operation for the customer side display unit 205 is received during the full self mode, in other words, For example, when the customer side operation has not been performed beyond the time limit, the forced end button BT14 displayed on the store clerk side display unit 210 is operated to forcibly end the POS terminal 20 and return to the full self mode. I am doing so. For this reason, even when a customer performs registration at the POS terminal 20 in the full self mode and the product registration is interrupted and left in the middle, the POS terminal 20 can be opened to other customers. Therefore, a decrease in the operation of the POS terminal 20 can be suppressed.

  Moreover, as a situation where there is no customer in the vicinity of the POS terminal 20, it is assumed that the customer who has started registration recalls a product forgot to buy and picks it up from the sales floor. In this case, the customer has interrupted the registration of the product, but is willing to resume. Even in this case, if the POS terminal 20 is forcibly terminated, there is a possibility that the trouble of re-registering the same product may occur. In this regard, since the POS terminal 20 has a time limit before the forced termination, even if there is no customer in the vicinity of the POS terminal 20, the POS terminal 20 is not immediately forced to be terminated. Save time and effort. Assuming a case where a customer who has started registration recalls a product that he forgot to buy and picks it up from the sales floor, the time limit is preferably about 5 minutes, for example. Alternatively, the time limit may be set based on the size of the sales floor or past information. Furthermore, the time limit may be set based on information such as the date (day of the week).

  The forced termination of the POS terminal 20 is performed based on an operation of pressing the forced termination button BT14 displayed on the store clerk display unit 210. For this reason, since it is possible to prevent customers from forcibly terminating, troubles between customers can be avoided. In addition, when the clerk knows the circumstances of the customer leaving the POS terminal 20, the forced termination is not performed even if the time limit is greatly exceeded. Can alleviate discomfort for customers.

  When the POS terminal 20 is forcibly terminated, the registration information of the product registered in the customer side display unit 205 or the customer side scanner unit 206 is discarded. For this reason, for example, when the customer is forced to end by leaving the POS terminal 20, it is possible to reduce the burden on the settlement process. Note that registration information may be suspended without being discarded.

  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.

(About error display)
In the POS terminal 20 described above, when the transition of the operation mode is prohibited, for example, in the normal mode or the full self mode, the first mode switching button BT12 or the second mode switching button BT13 is operated before the settlement after starting the registration. If this happens, the operation mode continues without shifting to the full self mode or the normal mode. At this time, even if the first mode switching button BT12 or the second mode switching button BT13 is operated, the operation of the first mode switching button BT12 or the second mode switching button BT13 is performed on the store clerk side display unit 210 or the customer side display unit 205. Although the display based on is not performed, an error display based on the operation of the first mode switching button BT12 or the second mode switching button BT13 may be performed. By performing such an error display, the store clerk can easily recognize the prohibition of switching of the operation mode.

  For example, when the operation mode is the normal mode and the first mode switching button BT12 is operated before the settlement after the start of registration, the display based on the operation of the first mode switching button BT12 is shown in FIG. Thus, the error screen during the normal mode may be displayed. The normal mode error screen is a screen in which the normal mode error display GA50 is displayed on the screen displayed on the clerk-side display unit 210 in the normal mode. In the normal mode error display GA50, a message “Error product registration (payment in progress). Do you want to switch to full self and entrust product registration?” And the text “Let ’s entrust”. Is displayed, and a reject button BT52 on which the text “No” is written is displayed.

  Among these, when the clerk presses the accept button BT51, the operation mode shifts from the normal mode to the full self mode. When transitioning to the full self mode, a registration screen shown in FIG. Further, a mirror screen shown in FIG. 14B is displayed on the clerk side display unit 210. For this reason, in principle, the transition from the normal mode to the full self mode is prohibited before the settlement after the start of registration. Transition from mode to full self mode is possible. When shifting from the normal mode to the full self mode, the store clerk may perform a product registration process in the normal mode. In this case, the registration process information is directly taken over in the full self mode. For this reason, since duplication of registration processing can be suppressed and a burden can be reduced, settlement can be performed smoothly. When the clerk presses the reject button BT52, the normal mode error display GA50 is deleted while the operation mode remains in the normal mode.

  In addition, when the operation mode is the full self mode and the second mode switching button BT13 is operated before the settlement after the registration is started, the display based on the operation of the second mode switching button BT13 is shown in FIG. As shown, an error screen during the full self mode may be displayed. The error screen during full self mode is a screen in which the error display GA60 during full self mode is displayed on the screen displayed on the clerk side display unit 210 during the full self mode. In full self mode error display GA60, the message “Error customer is in use. Do you want to switch to face-to-face self and take over product registration?” Is displayed, and the text “takeover” is written. An acceptance button BT61 and a reject button BT62 on which characters “No” are written are displayed.

  Among these, when the clerk presses the acceptance button BT61, the operation mode shifts from the full self mode to the normal mode. When the mode is shifted to the normal mode, a registration screen shown in FIG. Further, the customer side display unit 205 displays a screen shown in FIG. For this reason, in principle, the transition from the full self mode to the normal mode is prohibited before the settlement after the start of registration. However, when there is an operation mode transition request (pressing the acceptance button BT61) by a store clerk or the like, Transition from the self mode to the normal mode is possible. When shifting from the full self mode to the normal mode, the customer may perform a product registration process in the full self mode. In this case, the registration process information is directly taken over in the normal mode. For this reason, since duplication of registration processing can be suppressed and a burden can be reduced, settlement can be performed smoothly. When the clerk presses the reject button BT62, the error display GA60 in the full self mode is erased while the operation mode remains in the full self mode.

  If the operation mode is the full self mode and the forced end button BT14 is operated before the acceptance of the forced end button BT14 shown in FIG. 15 is started, the display based on the operation of the forced end button BT14 is shown in FIG. As shown in FIG. 6, an error screen before forced termination may be displayed. The error screen before forced termination is a screen in which the error display GA70 before forced termination is displayed on the screen displayed on the clerk side display unit 210 in the full self mode. In the error display GA70 before forcible termination, a message “Error product registration (payment) is in progress. The mode cannot be changed.” Is displayed, and a cancel button BT71 with a text “Delete” is displayed. Is displayed. By depressing this cancel button BT71, the error display GA70 before forcible termination is erased while the operation mode remains in the full self mode.

  When there is an operation mode transition request (pressing the accept button BT51) by a clerk or the like shown in FIG. 16A, and the clerk is performing a product registration process when transitioning from the normal mode to the full self mode, Registration information registered during the mode may not be transferred to the full self mode. Similarly, when there is an operation mode request (pressing of the accept button BT61) by a store clerk or the like shown in FIG. 16B, and the customer is performing a product registration process when shifting from the full self mode to the normal mode, The registration information registered in the full self mode may not be transferred to the normal mode. In these cases, instead of not being able to take over the registration information registered in the normal mode or the full self mode before switching, for example, this registration information may be discarded or put on hold. If the registration information is discarded, subsequent processing confusion can be avoided. Further, when the registration information is suspended, the subsequent settlement process can be performed smoothly.

  For example, when the accept button BT61 shown in FIG. 16B is pressed, the operation mode shifts from the full self mode to the normal mode. At this time, the clerk-side display unit 210 displays the operation mode shown in FIG. A registered information processing selection screen is displayed. The registered information selection screen is a screen in which a registered information processing selection display GA80 is displayed on the screen displayed on the clerk side display unit 210 during the full self mode. In the registered information processing selection display GA80, a message “Move to face-to-face self. There is registered data. Are you sure you want to discard / hold?” And the text “Discard” is entered. A discard button BT81 and a hold button BT82 on which characters “hold” are written are displayed.

  Among these, when the store clerk presses the discard button BT81, the registration information registered in the full self mode is discarded, and the registration start screen in the normal mode shown in FIG. When the hold button BT82 is pressed, a registration start screen in the normal mode shown in FIG. In the registration start screen shown in FIG. 18B, a first hold display tab TAB91 and a second hold display button BT92 relating to the held registration information are displayed. By depressing these first hold display tab TAB91 and second hold display button BT92, an image including held registration information, amount information, etc. is displayed, and a transaction including the held registration information is resumed. Can do.

  When holding registration information, only one of the first hold display tab TAB 91 and the second hold display button BT 92 may be displayed, or the hold display button or the like may be displayed in another manner. Alternatively, registration information (transaction information) that can be called in the form of a pending receipt may be printed as code information such as a barcode. Further, when resuming the transaction, the transaction may be resumed in the mode at the time of holding (here, the full self mode) or may be resumed in the current mode (here, the normal mode). Or you may enable it to select the operation mode at the time of restart.

(About the timing start condition)
In the above example, when the customer's operation is last (when the customer performs the last operation) is the timing start condition for starting timing by the timer, the timing start condition may be other conditions. . For example, the customer may be away from the POS terminal 20. In order to determine when the customer is away from the POS terminal 20, for example, a human sensor that detects a person at the POS terminal 20 as a customer is provided, and the human sensor cannot identify a person (customer). It may be determined that the customer is away.

(Customer image registration)
Alternatively, the POS terminal 20 may be provided with imaging means (camera) for imaging the customer side, and an image (customer image) of the customer's face or the like may be captured. The customer image is captured when the transaction is started, and stored in the RAM 203 or the like in association with a transaction code (automatic numbering) attached to each transaction, or the face image data is stored in the store controller 10. Or may be stored in the store controller 10.

  Further, when the registration information is discarded or suspended, a customer image may be acquired. The customer image to be acquired may be, for example, a customer image stored in the RAM 203 of the POS terminal 20, a customer image stored in the store controller 10, or a customer image number (code) associated with these customer images. Good. By acquiring the customer image, it is possible to easily identify the customer who registered the discarded or stored registration information.

  Further, instead of the photographing means or together with the photographing means, a specifying means for specifying the customer may be provided. As the specifying means, for example, a recorder for recording a customer's voice, or a customer's fingerprint or vein may be stored and used for specifying a customer. Alternatively, when the customer owns a membership card or the like and has an ID number or the like assigned to each customer, the ID number or the like may be stored and used to identify the customer. These identification means can also easily identify the customer who registered the discarded or stored registration information.

(About operation mode)
The POS terminal 20 uses the first mode switching button BT12 or the second mode switching button BT13 until there is registration or payment of the purchased product (after the settlement is completed if there was a process from registration to settlement last time). Is pressed to switch from the normal mode to the full self mode, and from the full self mode to the normal mode, and when in the full self mode, the second mode switching button BT13 is pressed to shift from the full self mode to the double scan mode. However, it may be shifted under other conditions. For example, the operation mode of the POS terminal 20 may shift according to an operation other than the explicit mode shift operation by the store clerk (for example, reading of the store clerk code). For example, in the full self mode, when the purchased product is not yet settled after registration, the POS terminal 20 is caused to read the clerk code instead of pressing the second mode switching button BT13 or when the second mode switching button BT13 is pressed. Thus, the full self mode may be shifted to the double scan mode.

  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. ) Or the operation mode may be shifted. Specifically, for example, the POS terminal 20 in the normal mode is not used until the purchase product is registered or received (after the settlement is completed in the case of processing from registration to settlement in the previous time). If this state continues, the mode may shift to the full self 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. . Moreover, instead of the operation of pressing the second mode switching button BT13 displayed on the store clerk side display unit 210, the operation mode may be shifted 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.

(About semi-self mode)
The POS terminal 20 is used alone and performs registration and settlement of merchandise with the POS terminal. However, a POS system in which a plurality of POS terminals 20 are connected via a LAN or the like is used, and registration and settlement are performed with different POS terminals 20. May be. For example, the product registered at the first POS terminal 20-1 may be settled at the second POS terminal 20-2. The POS terminal 20 that performs settlement includes a normal mode, a full self mode, and a double scan mode as operation modes, and a semi-self mode (accounting only mode) that performs only settlement without registering products. As an aspect of operating the POS terminals 20 in the semi-self mode, for example, in two or more POS terminals 20, some POS terminals 20 are operated in the normal mode (registration-only mode), and the other POS terminals 20 are operated in the semi-self mode. There is a mode of operating in (settlement-only mode). Hereinafter, of the first POS terminal 20-1 and the second POS terminal 20-2 shown in FIG. 1, the first POS terminal 20-1 in the registration-only mode is referred to as the registration-only first POS terminal 20-1, and the second POS in the semi-self mode. The semi-self mode will be described using the terminal 20-2 as the accounting-specific second POS terminal 20-2.

  In the case where the second POS terminal 20-2 is set to the semi-self mode and the second POS terminal 20-2 is dedicated to accounting, the store clerk registers the customer's purchased products at the first dedicated registration POS terminal 20-1. When the registration process by the store clerk is completed, the customer moves to the accounting-only second POS terminal 20-2, confirms the total amount of the purchased product on the store clerk side display unit 210, inserts money into the change machine 209, or card The settlement unit 208 is operated and settled. That is, the accounting-dedicated second POS terminal 20-2 executes the settlement process by a customer operation or the like.

  When the registration process is completed in the registration-dedicated first POS terminal 20-1, the customer moves from the registration-dedicated first POS terminal 20-1 to the accounting-dedicated second POS terminal 20-2. -2 is supplied with information necessary for the settlement process such as registration information from the registration-only first POS terminal 20-1. As a method for supplying registration information and the like, information necessary for the settlement process is transmitted from the registration-specific first POS terminal 20-1 to the accounting-specific second POS terminal 20-2 (may be transmitted via the store controller 30). And a method of issuing a medium (a medium on which a bar code or the like for obtaining information necessary for the checkout process) is issued in the registration-purpose first POS terminal 20-1.

  If there are two or more accounting-dedicated second POS terminals 20-2, even if the registration-dedicated first POS terminal 20-1 designates the accounting-dedicated second POS terminal 20-2 for executing the settlement process. Good. When the registration-dedicated first POS terminal 20-1 issues a medium (a medium on which a bar code or the like for obtaining information necessary for the settlement process is printed), the accounting-dedicated second POS that has read the medium is issued. The settlement process is executed in the terminal 20-2.

  That is, in the semi-self mode, first, merchandise is registered on the clerk side of the registration-only first POS terminal 20-1. For example, the merchandise is registered by scanning the clerk side scanner unit 212 of the registration-only first POS terminal 20-1. After the subtotal key (for example, the subtotal key displayed on the store clerk side display unit 210 or the subtotal key arranged on the key operation unit 211) is pressed, for example, the accounting-dedicated second POS terminal 20-2 is designated. The registration information is transmitted to the designated transaction-specific second POS terminal 20-2, and the processing is completed.

  In the above example, at the end of product registration, the subtotal key is pressed first, and then (after the subtotal key is pressed), the processing procedure is to designate the accounting-specific second POS terminal 20-2. At the end, the processing procedure may be such that the accounting-specific second POS terminal 20-2 is specified directly (without pressing the subtotal key). In the latter case, the subtotal key may not be displayed on the screen.

  Subsequently, the accounting-dedicated second POS terminal 20-2 designated by the registration-dedicated first POS terminal 20-1 receives the registration information, and then, at the customer side, for example, the change machine 209 performs settlement (step S50), and processing Is completed. In addition, in the registration-dedicated first POS terminal 20-1, the store clerk can register the purchased product of the next customer after transmitting the registration information (or after issuing the medium). Further, the store clerk may be absent after transmitting the registration information.

  In the above example, the accounting-only second POS terminal 20-2 executes the settlement process using the registration information of the product registered in the registration-only first POS terminal 20-1. That is, the registration information used by the accounting-only second POS terminal 20-2 for the checkout process is the registration information of the product registered when the registration-only first POS terminal 20-1 is operating in the registration-only mode. However, if the registration information can be transmitted to the accounting-specific second POS terminal 20-2 (or if an accounting ticket (registered trademark, the same applies hereinafter) can be issued), the accounting-specific second POS terminal 20-2 pays out. The registration information used for the process does not necessarily have to be the registration information of the product registered when the first POS terminal 20-1 is operating in the registration-only mode.

  Further, when the accounting-only second POS terminal 20-2 is operating in the accounting-only mode, the accounting-only second POS terminal 20-2 receives the registration information (or reads the bill) and executes the settlement process. However, if the checkout process can be executed after receiving the registration information (or after reading the bill), the second POS terminal 20-2 receives the registration information (or reads the bill). The operation mode is not necessarily the accounting-only mode.

  As an example, when the second POS terminal 20-2 is operating in the full self mode, the second POS terminal 20-2 receives registration information from another terminal (for example, the first POS terminal 20-1) and uses the registration information received from the other terminal. The settlement process may be executed. Further, when the second POS terminal 20-2 is operating in the full self mode, the second POS terminal 20-2 reads the bill issued by the other terminal (for example, the first POS terminal 20-1), and the bill read from the other terminal. The settlement process may be executed using the registration information obtained from the ticket.

  In this case, the second POS terminal 20-2 shifts from the full self mode to the accounting-only mode before executing the settlement process using the registration information received from the other terminal (received from the other terminal as the settlement process in the accounting-only mode). Processed registration information). In addition, the second POS terminal 20-2 shifts from the full self mode to the accounting-only mode before executing the settlement process using the bill issued at the other terminal (as a settlement process in the accounting-only mode, at the other terminal). Process registration information based on issued bills).

  Note that the second POS terminal 20-2 does not need to shift from the full self mode to the accounting-only mode before executing the settlement process using the registration information received from the other terminals (as a settlement process in the full self mode, other Registration information received from the terminal may be processed). Further, the second POS terminal 20-2 does not have to shift from the full self mode to the accounting dedicated mode before executing the settlement process using the bill issued at the other terminal (the settlement process in the full self mode). As well as registration information based on bills issued at other terminals). In these cases, data transmission / reception may be performed between the plurality of POS terminals 20, and registration / settlement processing may be performed between the plurality of POS terminals.

  Further, after the POS terminal 20 operating in the normal mode or the like receives a transition instruction from another POS terminal 20, if the local POS terminal 20 is processing, the POS terminal 20 shifts to the semi-self mode (accounting only mode) after the processing is completed. , After receiving the transition instruction, the mode may be forcibly (immediately) shifted to the semi-self mode (accounting only mode). For example, when the store clerk is performing registration processing on the store clerk side, if the shift instruction is received, the normal mode is immediately shifted to the semi-self mode (accounting 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 (accounting 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 a transmission button of a POS terminal that can be a transmission destination (a POS terminal 20 that operates in a semi-self mode (accounting-only mode) or a POS terminal 20 in a 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, 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 restricted (prohibited) 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).

(Display in double scan mode)
In the above example, in the double scan mode, a change screen (see FIG. 12A) is displayed when the registration completion key (end (receipt) button BT40) displayed on the customer display unit 205 is pressed. Yes. In other words, the product registration is completed by the customer (registration completion key). However, the aspect of completing the product registration is not limited to this.

  For example, when a subtotal key is displayed on the clerk side display unit 210 and either the subtotal key displayed on the clerk side display unit 210 or the registration completion key displayed on the customer side display unit 205 is pressed, the change is made. A screen may be displayed. That is, both the store clerk and the customer may be able to perform an operation for completing the product registration.

  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.

  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, but the next customer's product may be registered. Good. 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 the above, during the double scan mode, during product registration (registration screen), in the store clerk side display unit 210, the product registered on the own side (store clerk side) and the product registered on the other side (customer side) Are displayed in different display modes, and the customer side display unit 205 displays the products registered on the customer side (customer side) and the products registered on the partner side (store clerk side) in different display modes. The display mode in the 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, the store clerk side display unit 210 displays the product registered on its own side (store clerk side) and the product registered on the other party side (customer side) in different display modes, and the customer side display unit 205 displays the other side (store clerk). The product registered on the customer side may be displayed without displaying the product registered on the customer side. Alternatively, the store clerk side display unit 210 displays the product registered on the own side (store clerk side) without displaying the product registered on the partner side (customer side), and the customer side display unit 205 displays the product registered on the customer side (customer side). ) And the product registered on the other party (the 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.

  During product registration, the product registered on the other side and the product registered on the other side are displayed in different display areas. After product registration, the product registered on the other side and the other side are displayed. The registered product 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.

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

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

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

  Whether or not to display the product name or the like of the product registered by the customer on the clerk side display unit 210 in the full self mode in the clerk login state is determined by the clerk side (the clerk side display unit 210) or the customer side (the customer side display unit 205). ) At least one of them may be set.

  Note that the login state of the POS terminal 20 is canceled based on an explicit operation (logout operation) by the store clerk (from the login state to the logout state). In place of or in addition to the explicit operation of the store clerk, if the specified time (for example, can be set for each terminal) has elapsed since the last operation by the store clerk (if no operation has been performed for a predetermined time), the login state is canceled You may be made to do.

  Note that the above-described hibernation state (pause mode) and logout state may be the same. That is, the logout operation described above is a pause button operation. However, the hibernation state and the logout state may be different states. For example, the dormant state (pause mode) may be a part of the login state (a state that shifts when the pause button is operated in the login state). When it is considered that the hibernation state and the logout state are different states, the logout operation is an operation different from the operation of the pause button.

  However, for products that require clerk intervention (for example, products that require heating by a range, or products that the clerk takes out (meat, cigarettes, etc.)), it is necessary to inform the clerk of the product, regardless of the above settings. May be displayed on the clerk side display unit 210. Further, since it is necessary to inform the store clerk about products (for example, cigarettes, alcoholic beverages, etc.) that require age authentication, they may be displayed on the store clerk display unit 210 regardless of the above settings. It should be noted that whether or not the product requires the intervention of a store clerk may be determined in advance for each product.

(About the printing department)
In the above description, the POS terminal 20 includes one printing unit 213 that can freely change the direction (direction of the medium issuing port) from the clerk side to the customer side and from the customer side to the clerk side. Two printing units having an issuing port may be provided. In other words, the POS terminal 20 has a clerk side printing unit having a medium issuing port on the clerk side and a medium issuing port on the customer side instead of the single printing unit 213 that can change the direction of the medium issuing port in a rotatable manner. A certain customer-side printing unit may be provided separately.

(About the scanner section)
In the above description, the customer-side scanner unit 206 is of a type that is held by an operator (a store clerk or a customer) and recognizes identification information close to an object (a product or the like). There may be. For example, it may be a fixed type that recognizes the object closer. The same applies to the clerk side scanner unit 212.

(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 such as product information and registration information, and other output information (including information related to customers). 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.) and the registration status of store staff and customers in double scan mode (ratio of the number of product registration between store staff and customers, etc.) Etc., it may be customer-specific). 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.

(About other indications)
Further, on the POS terminal 20, for example, information related to an error or the like (for example, a warning about change, a warning about paper, information about a call of a clerk, etc.) may be displayed. In addition, information related to other POS terminals 20 may be displayed by transmitting / receiving information via the LAN 11 instead of or in addition to the information related to the POS terminal 20. Further, when displaying information related to another POS terminal 20, display according to the position of the other POS terminal 20 (positional relationship with the POS terminal 20) may be performed.

  Each POS terminal 20 refers to information indicating the positional relationship with other POS terminals 20 (for example, each POS terminal 20 itself may store and refer to information indicating the positional relationship, The store controller 10 stores information indicating the positional relationship, and each POS terminal 20 may access the store controller 10 and refer to the information indicating the positional relationship), depending on the position of another POS terminal 20 Display may be performed. Alternatively, the display position may be determined in advance for each of the other POS terminals 20.

  For example, the left and right display positions may be varied depending on the arrangement of the POS terminal 20. As an example, the first POS terminal 20-1 is arranged on the left side (left side as viewed from the store clerk side) of the second POS terminal 20-2, and the third POS terminal 20 is located on the right side (right side as viewed from the store clerk side) of the second POS terminal 20-2. -3 is arranged (that is, when viewed from the clerk side display unit 210 side, the first POS terminal 20-1 is arranged on the left side, the second POS terminal 20-2 is arranged in the center of the left and right, and on the right side. In the case where the third POS terminal 20-3 is arranged), the first POS located on the left side of the second POS terminal 20-2 in the clerk side display unit 210 of the second POS terminal 20-2 arranged in the center of the left and right. Information regarding the terminal 20-1 may be displayed on the left side of the screen, and information regarding the third POS terminal 20-3 positioned on the right side of the second POS terminal 20-2 may be displayed on the right side of the screen.

  Further, in the clerk side display unit 210 of the first POS terminal 20-1 arranged on the left side, information on the second POS terminal 20-2 and the third POS terminal 20-3 located on the right side with respect to the first POS terminal 20-1. May be displayed on the right side of the screen. For example, information related to the third POS terminal 20-3 located farther from the first POS terminal 20-1 is placed on the right side than information related to the second POS terminal 20-2 located closer to the first POS terminal 20-1. It may be displayed. Similarly, in the clerk side display unit 210 of the third POS terminal 20-3 arranged on the right side, the first POS terminal 20-1 and the second POS terminal 20-2 located on the left side with respect to the third POS terminal 20-3. Information may be displayed on the left side of the screen. For example, information on the first POS terminal 20-1 located farther from the third POS terminal 20-3 is placed on the left side than information on the second POS terminal 20-2 located closer to the first POS terminal 20-1. It may be displayed.

  Further, the example shown in FIG. 1 is a display example when three POS terminals 20 are arranged in the store, but the same may be applied to the case where two or four or more terminals are provided. In the above, the current operation mode of the own POS terminal 20 is notified (displayed). For example, by acquiring information related to the operation mode in the other POS terminal 20 via the LAN 11, the other POS terminal 20 The 20 current operation modes may also be notified (displayed).
