<First Embodiment>
FIG. 1 shows an outline of a store in which the sales system of the present embodiment is used. The store in which the sales system of the present embodiment is used is operated, for example, in a commercial facility (for example, a department store, a shopping center, a station yard, etc.). As an example of the store of the present embodiment, a case where food is sold will be taken as an example.
In the display case shown in the figure, various foods are displayed as products.
A plurality of registered settlement devices 10 are installed on the display case. The registration settlement device 10 includes a scale 109a on which a product for weighing is placed.

Customer C instructs the clerk S about the product to be purchased and the weight (or amount) to be purchased. The clerk S performs an operation of designating the product instructed by the customer C as a registration target on the registration settlement device 10. Then, the clerk S measures the weight of the product to be registered (or the weight corresponding to the amount of money instructed by the customer C) by the registration settlement device 10. At this time, the clerk S weighs the product by placing it on the scale 109a.
The registration settlement device 10 calculates the price of the product based on the weighed weight and the unit weight per unit weight (for example, 100 g) set for the product, and together with the price of the product, the product designated as the registration target. Register. The customer C instructs the clerk S about the weight of each product he / she wants to purchase as described above, and the clerk S measures the weight of the instructed product and registers the product.
After instructing the clerk S about all the products to be purchased, the customer C gives the clerk S an amount (amount equal to or more than the total amount) corresponding to the total amount of the registered products calculated by the registration settlement device 10. The clerk S inputs the amount of money given by the customer C as the deposit amount and causes the registered settlement device 10 to perform the settlement process. The clerk S hands the purchased product and the receipt to the customer C, and if there is change, also hands the change to the customer C to complete the transaction with the customer C.

FIG. 2 shows a configuration example of the sales system according to the present embodiment. The sales system shown in the figure includes a registration settlement device 10-1 to 10-3, an electronic product tag 20-1 to 20-5, and a clerk identification tag 30-1 to 30-3.
In this specification, when the registered settlement devices 10-1 to 10-3 are not particularly distinguished, they are referred to as the registered settlement devices 10. Further, when the electronic product tags 20-1 to 20-5 are not particularly distinguished, they are described as the electronic product tags 20. Further, when the clerk identification tags 30-1 to 30-3 are not particularly distinguished, they are described as the clerk identification tag 30.

As described above, the registration settlement device 10 performs the product registration process according to the product registration operation and the settlement process for the registered product. At the time of product registration processing, the registration settlement device 10 calculates the amount of money for each product based on the weight of the product placed on the scale 109a and the weight unit price.
The registration settlement devices 10 are connected so as to be able to communicate with each other. By enabling the registered settlement devices 10 to communicate with each other, "product registration takeover" becomes possible.
In the product registration takeover, after the clerk registers the product in one transaction with one registered settlement device 10, the clerk moves to the other registered settlement device 10 and registers the product in the same transaction. That is. In the product registration transfer, in the same one transaction, the product registration information corresponding to the product registration previously performed by the registration settlement device 10 is transferred to the next registration settlement device 10. The next registration settlement device 10 can add information about the product registered by its own product registration process to the inherited product registration information.

By enabling such "product registration takeover", for example, the customer C can specify a product displayed at a position away from the registration settlement device 10 currently operated by the clerk S. is there. In such a case, the clerk S can go to the designated product, take out the product, and continue the registration of the product by another registration settlement device 10 installed at the nearest place.
Although the figure shows a case where three registered settlement devices 10 are provided, the number of registered settlement devices 10 installed in the sales system is not particularly limited.

Each of the electronic product tags 20 is installed toward the clerk corresponding to each displayed product. Each of the electronic product tags 20 can communicate with each of the registered settlement devices 10 by a predetermined short-distance compatible wireless communication method.
Each of the electronic product tag 20 stores the electronic product tag number. The electronic product tag number is a number assigned to each electronic product tag 20, and is associated with one product. The electronic product tag 20 is installed at a position corresponding to the place where the product associated with the electronic product tag number is displayed.
The electronic product tag 20 includes a vibration sensor that detects vibration.
For example, when a product is instructed by the customer C, the clerk S performs an operation of touching the electronic product tag 20 corresponding to the instructed product. The electronic product tag 20 detects vibration in response to a touch operation, and transmits the electronic product tag number stored by itself to the registration settlement device 10. The registration settlement device 10 sets the product associated with the received electronic product tag number as the product to be registered in response to the reception of the electronic product tag number.
In the figure, an example in which five electronic product tags 20 of electronic product tags 20-1 to 20-5 are arranged is shown, but the number of electronic product tags 20 is the number of products to be displayed. It is changed as appropriate according to.
The electronic product tag 20 can be configured by, for example, an RFID (Radio Frequency IDentifier) tag or the like.

The clerk identification tag 30 (an example of a storage medium) is carried by each clerk who sells products at the store. The clerk identification tag 30 is provided on, for example, a name tag that the clerk attaches to clothes or the like. Each of the clerk identification tags 30 stores clerk information including a clerk identifier that uniquely indicates one clerk. The clerk S wears a clerk identification tag 30 in which his / her clerk information is stored. The clerk identification tag 30 may be provided on, for example, a wristband attached to the wrist.
The clerk identification tag 30 enables wireless communication (non-contact type communication) with the registration settlement device 10 with a communication distance of, for example, several meters. Such a clerk identification tag 30 can be configured by, for example, an RFID tag.
The clerk identification tag 30 can communicate with the registration settlement device 10 when, for example, a clerk wearing the clerk identification tag 30 approaches the registration settlement device 10 within a communication distance. The clerk identification tag 30 transmits the stored clerk information to the registered settlement device 10 of the communication partner in response to being able to communicate with the registration settlement device 10. As a result, the registration settlement device 10 can acquire the clerk information from one or more clerk identification tags 30 in a state in which communication is possible.
Then, the registration settlement device 10 of the present embodiment sets the clerk indicated by the clerk information acquired from the clerk identification tag 30 having the strongest reception strength among the communicable clerk identification tags 30 as its own "handler". To do. Among the communicable clerk identification tags 30, the clerk identification tag 30 having the strongest reception strength is the clerk identification tag 30 located at the position closest to the registration settlement device 10. That is, the clerk identification tag 30 of the clerk closest to the registration settlement device 10. The clerk who intends to operate the registered settlement device 10 in response to an order from a customer is usually at the position closest to the registered settlement device 10 among the clerk in the store. Therefore, the registration settlement device 10 of the present embodiment sets a clerk who is most likely to operate himself / herself to make an account as a “handler”.
In the present embodiment, the "handler" is a clerk who operates the registration settlement device 10 for accounting. Further, in the present embodiment, "accounting" includes product registration and settlement in one transaction.

In the figure, three clerk identification tags 30-1 to 30-3, which are clerk identification tags 30-1 to 30-3, are shown. However, the number of clerk identification tags 30 provided in the sales system is appropriately changed according to the number of clerk who conducts sales business in the store.

The electronic product tag 20 in the present embodiment may be capable of acquiring clerk information by communicating with, for example, a clerk identification tag 30 located within a communication distance. The electronic product tag 20 acquires clerk information from the clerk identification tag 30 that can communicate at that time, for example, in response to a touch operation. The electronic product tag 20 searches for the registration settlement device 10 in which the clerk indicated by the acquired clerk information is set as the handler. For example, when a clerk who touches the electronic product tag 20 approaches one registration settlement device 10 in order to register the product, the registration settlement device 10 sets the handler. The electronic product tag 20 succeeds in searching for the registration settlement device 10 in which the clerk who has touched the electronic product tag 20 is set as the handler. The electronic product tag 20 transmits the product information to the searched registration settlement device 10. The registration settlement device 10 that has received the product information displays a registration screen for the product indicated by the received product information.
As a result of such control, the registration screen based on the product information transmitted from the touch-operated electronic product tag 20 is displayed only in the registration settlement device 10 operated by the clerk who touch-operates the electronic product tag 20. Will be. On the other hand, the registration settlement device 10 in which a clerk other than the clerk who touched the electronic product tag 20 is set as the handler can prevent the registration screen related to the extra product from being displayed.

A configuration example of the registration settlement device 10 in the present embodiment will be described with reference to FIGS. 3 and 4. FIG. 3 is a block diagram showing a hardware configuration example of the registration settlement device 10. FIG. 4 is a perspective view showing an external example of the registered settlement device 10. Specifically, FIG. 4 (A) is a view of the registered settlement device 10 from the clerk S side, and FIG. 4 (B) is a view of the registered settlement device 10 from the customer C side.

A measuring unit 109, a printing unit 110, an inter-device communication unit 111, a short-range communication unit 112, and a drawer 113 are provided. These are connected to each other via bus 119.

By executing the program, the CPU 101 executes various processes for realizing the functions of the registration settlement device 10.
The ROM 102 stores various information. For example, a program executed by the CPU 101 is stored. Further, the ROM 102 stores information (screen information, message information, etc.) related to the display by the store clerk display unit 105 and the customer display unit 106. Further, the ROM 102 stores a device number (device identifier) for identifying the own device. Further, the ROM 102 may store information (print contents, print format information, etc.) related to printing by the printing unit 110.
The RAM 103 is used as a work area for the CPU 101 to execute processing and calculation.

The scanner unit 104 optically reads the coded information. For example, as shown in FIGS. 4A and 4B, the scanner unit 104 is installed at a position that is difficult for the customer C to see.

As shown in FIG. 4A, the clerk display unit 105 is arranged toward the clerk S side. The clerk display unit 105 is configured as a touch panel, and accepts an operation by touching the displayed operation screen with an operating body such as a finger.

As shown in FIG. 4B, the customer display unit 106 is arranged toward the customer C side and displays for the customer. The customer display unit 106 may be configured as a touch panel so that it can be operated by the customer C.

The hard disk 107 stores, for example, a product file or the like. The hard disk 107 may store a program for causing the CPU 101 to execute registration processing, settlement processing, and the like. Further, the hard disk 107 may store various information (for example, transaction information) generated by executing the program. Further, the hard disk 107 may store information related to display by the store clerk display unit 105 and customer display unit 106, and information related to printing by the printing unit 110.
An SSD (Solid State Drive) may be provided instead of the hard disk 107.

As shown in FIG. 4A, the key operation unit 108 has various operation keys (number key, cancel key, tare key, additional key, product number key, execution key, etc.) for receiving various operations from the clerk. ) Is provided.

The weighing unit 109 weighs the product or the like (the product and the tare containing the product) placed on the scale 109a, and outputs data indicating the measured value to the CPU 101. The CPU 101, which has acquired the measured value from the measuring unit 109, subtracts a predetermined weight (weight of the tare) from the measured value to calculate the product placed on the scale 109a. Further, the CPU 101 temporarily stores the weight of the product calculated as described above in the RAM 103, and displays the weight on the display unit (clerk display unit 105, customer display unit 106).

The printing unit 110 prints on paper and issues (outputs) a receipt or label from an issuing port (see FIG. 4A). For example, the printing unit 110 can load a paper cassette. Paper cassettes include a paper cassette for receipts and a paper cassette for labels (for example, with glue), and the printing unit 110 can be loaded by exchanging these cassettes. Has been done. For example, during business, a cassette of paper for receipt is loaded in the printing unit 110, and a receipt reflecting the result of the transaction is produced according to the completion of processing from registration of the product corresponding to one transaction to settlement. It is issued from the printing unit 110 and handed to the customer. Further, for example, when a product is being prepared before the start of business hours, the clerk loads a cassette of label paper into the printing unit 110 and attaches the label to the product for product management, for example. A label can be issued from the printing unit 110 according to an operation for creating a label.

The inter-device communication unit 111 communicates with another registered settlement device 10 via a predetermined communication network. The communication network supported by the inter-device communication unit 111 may be wired or wireless.
The short-range communication unit 112 wirelessly communicates with the electronic product tag 20. In addition, the short-range communication unit 112 communicates with the clerk identification tag 30. The short-range communication unit 112 may be set so that, for example, the communication distance with the electronic product tag 20 and the communication distance with the clerk identification tag 30 are different. For example, with respect to the electronic product tag 20, it is preferable to set a wide communication distance so that communication with any of the electronic product tags 20 arranged in the display case is possible. On the other hand, the clerk identification tag 30 can communicate with the operating registration settlement device 10 while the clerk S is operating the registration settlement device 10, but communicates with other registration settlement devices 10. It is preferable to set a short communication distance so that the above is not performed.

The drawer 113 has a storage unit for storing money (banknotes and coins), and the storage unit is pulled out to the front surface (in the direction of the arrow in FIG. 4A) in response to the operation of the clerk S. The clerk S can store the money received from the customer as the price in the drawer 113. Further, when the clerk S hands the change to the customer C, the clerk S can take out the money corresponding to the amount of the change from the drawer 113 and hand it to the customer C.

As shown in FIG. 4A, the electronic product tag 20 is installed for each product toward the clerk S side. As shown in the figure, the electronic product tag 20 is provided with a display unit that displays a unit price (price per unit weight or unit number) and the like. By looking at the electronic product tag 20, the clerk S can grasp where and which product is placed, and can grasp the price of each product.
Further, as shown in FIG. 4B, a product tag 22 different from the electronic product tag 20 is installed for each product on the customer C side. Information for customer C, such as a product name and a price, is shown on the product tag 22.
The product tag 22 may have the same configuration as the electronic product tag 20 having a display unit.

Subsequently, with reference to FIGS. 5 to 8, an example of the operation of the registration settlement device 10 according to the operation of the clerk S in one transaction will be described. In the explanation of the figure, the case where the customer C purchases two products, "marinated salmon" and "roast beef", by one transaction will be described as an example.
Here, the customer C first told the clerk S that he would purchase 200 g of "marinated salmon". Therefore, the clerk S performs an operation of designating "marinated salmon" as a product to be registered by operating the product registration screen displayed on the clerk display unit 105.

FIG. 5 shows an example of a product registration screen after performing an operation of designating "marinated salmon" as a product to be registered.
In the product registration screen of the figure, the product name area AR1, the tare weight area AR11, the product weight area AR12, the content capacity area AR13, the weight unit price area AR14, and the product price area AR15 are arranged.
The product name area AR1 is an area in which the product name of the product designated as the registration target is displayed.
The tare weight area AR11 is an area in which the tare weight is displayed when a preset tare weight is called.
The product weight area AR12 is an area where the weight of the product to be registered measured by the measuring unit 109 is shown.
The content content area AR13 is an area in which the content content of the product to be registered is displayed.
The weight unit price area AR14 is an area in which the unit price (weight unit price) per unit weight (100 g) of the product to be registered is displayed when the product to be registered is sold by weight.
The product price area AR15 is an area in which a price (product price) according to the weight or content of the product to be registered is displayed.

Further, on the product registration screen of the figure, a product classification button BT1 (BT1-1, BT1-2) and a product button BT2 (BT2-1, BT2-2, BT2-3) are arranged.

The product classification button BT1 (BT-1, BT1-2) is a button on which an operation of designating the classification of the product to which the product to be registered is applicable is performed. In the case of the figure, two product classification buttons BT1-1 and BT1-2 are arranged as product classification buttons BT1. The product classification button BT1-1 corresponds to a product classified as "salad". The product classification button BT1-2 corresponds to a product classified as "side dish".
In this case, the "marinated salmon" designated by customer C is classified as a "side dish". Therefore, in this case, the clerk S first operates the product classification button BT1-2 to select the classification of "side dish" when designating the "marinated salmon" as the registration target. If the classification of "delicatessen" has already been selected, the clerk S does not have to operate the product classification button BT1-2. The number of product classification buttons BT1 may be changed according to the number of product classifications.

The product button BT2 is a button corresponding to each product belonging to the classification selected by operating the product classification button BT1. In the figure, an example in which three product buttons BT2-1, BT2-2, and BT2-3 are arranged as product buttons BT2 corresponding to products belonging to the category of "side dish" is shown.
The product button BT2-1 corresponds to "marinated salmon". The product button BT2-2 corresponds to roast beef. The product buttons BT2-3 correspond to "meat dumplings".

In this case, the clerk S operates the product button BT2-1 corresponding to the "marinated salmon" designated by the customer C. In response to the operation of the product button BT2-1, the registration settlement device 10 sets the "marinated salmon" corresponding to the product button BT2-1 as the product to be registered. As shown in the figure, "Marinated salmon" is displayed as the product name of the product to be registered in the product name area AR1 according to the fact that "Marinated salmon" is set as the product to be registered. To.

Further, on the product registration screen of the figure, a clerk button display area AR20 is provided. A clerk button is displayed in the clerk button display area AR20. The clerk button is a button having a function of indicating a clerk as a handler of the registration settlement device 10.
However, in the clerk button display area AR20 in the figure, the clerk button is not yet displayed. The state in which the clerk button is not displayed in the clerk button display area AR20 indicates that the handler of the registration settlement device 10 corresponding to this transaction has not yet been set. Further, in the weight unit price area AR14, it is shown that the weight unit price of "marinated salmon" is 398 yen. Further, at this stage, since the weight of the product has not been measured, "0" is displayed in the product price area AR15, and a valid amount of money is not shown.

Here, the display of the clerk button in the clerk button display area AR20 is performed based on the clerk information stored in the clerk identification tag 30 in a state where communication with the registration settlement device 10 is possible. In this state, when the clerk S is performing the operation of designating the "marinated salmon" as the product to be registered, the clerk S is sufficiently close to the registered settlement device 10 that is operating. The clerk identification tag 30 worn by the clerk S is located within the communication distance of the registered settlement device 10. Therefore, for example, the registration settlement device 10 is in a state where the clerk information of the clerk S has already been acquired. However, there is a high possibility that the order will be canceled until the operation of designating the first product to be registered in one transaction. Therefore, in the present embodiment, the clerk S who performed the operation is not yet determined as the handler until the operation of designating the first product to be registered in one transaction. Therefore, at the stage of the figure, the clerk button of the clerk S is not yet displayed in the clerk button display area AR20.

After designating "marinated salmon" as the product to be registered as described above, the clerk S takes out the "marinated salmon" from the display case and measures the amount of "marinated salmon" to 200 g. Adjust while weighing.

When starting the work of adjusting the amount of "marinated salmon" as described above, for example, a container is placed on the scale 109a, and the "marinated salmon" is placed in the container. At this time, the measuring unit 109 changes from the state in which the numerical value of the weight measured so far has not changed.
In this way, after the first product to be registered in one transaction is specified, the numerical value measured by the weighing unit 109 changes, that is, the weighing of the first product to be registered is performed. Being started means that customer C is less likely to cancel the order.
Therefore, in the present embodiment, in response to the start of weighing of the first product to be registered, the clerk obtained from the clerk identification tag 30 which is in a state of being able to communicate with the registration settlement device 10 at that time. The clerk button based on the information is displayed in the clerk button display area AR20. That is, in this case, a clerk button indicating the clerk S who is accounting by the registration settlement device 10 is displayed.

FIG. 6 shows an example of a product registration screen in a state where the clerk button is displayed as described above. In the figure, a clerk button BT30 showing the name of the clerk S with "Taro" is arranged in the clerk button display area AR20.
In the figure, the state when the adjustment of "marinated salmon" is completed so as to be 200 g is shown. Therefore, in the product weight area AR12, it is shown that the weight currently measured by the measuring unit 109 is 200 g. Further, in the product price area AR15, it is shown that the product price obtained by the weight of the product and the weight unit price is 796 yen. In addition, the number "1" is displayed on the clerk button BT30. This indicates that there is only one product registered so far as the progress of accounting in which the clerk "Taro" is the handler.

When the clerk S confirms that the name indicated by the displayed clerk button BT30 is his own, the clerk S performs an operation on the clerk button BT30 as a confirmation completion operation. In response to the operation of the clerk button BT30, the registration settlement device 10 determines (registers) the clerk corresponding to the clerk button BT30 as the handler. As a result, this transaction is managed in association with the clerk who has been confirmed as the handler.
Further, when the clerk S confirms that 200 g is in the weighed state, the clerk S performs a predetermined operation (product registration confirmation operation) for confirming the registration of 200 g of the "marinated salmon" that has been the target of registration.
The product registration confirmation operation is, for example, an operation for the “addition” button BT21 arranged on the product registration screen as shown in the figure. By the product registration confirmation operation, the registration of the product so far is confirmed, and the registration settlement device 10 is in a state where the registration of the next product can be accepted. If there is only one product to be registered in one transaction, the clerk does not operate the "addition" button BT21, but instead presses the "subtotal" button BT22 arranged on the product registration screen as shown in the figure. You can operate it. In response to this operation, the registration settlement device 10 shifts the display to the subplanning surface as soon as the registration of the product is confirmed.

In addition, customer C ordered 200 g of "marinated salmon" and then 250 g of "roast beef". Therefore, the clerk S performs the registration confirmation operation for the "marinated salmon" as described above, then removes the "marinated salmon" from the scale 109a, and then designates the "roast beef" as the product to be registered. The operation to be performed is performed on the registration settlement device 10. In this case, the clerk S operates the product button BT2-2 indicating "roast beef". In response to the operation of the product button BT2-2, the registration settlement device 10 sets "roast beef" as the product to be registered.

As described above, in the sales system of the present embodiment, the product registration can be taken over between the registered settlement devices 10. Therefore, the registration for "roast beef" may use a registration settlement device 10 different from the registration for "marinated salmon". However, here, for the sake of simplicity, an example will be given in which the registration of "roast beef" is performed using the same registration settlement device 10 as that of registration of "marinated salmon".

After designating "roast beef" as the product to be registered as described above, the clerk S takes out the "roast beef" from the display case and adjusts it while weighing it by the weighing unit 109 so that the amount of "roast beef" is 250 g. ..

FIG. 7 shows an example of the product registration screen at the stage when the adjustment is completed so that the weight of the “roast beef” is 250 g. In the figure, the product weight area AR12 shows that the weight currently measured by the weighing unit 109 is 250 g. Further, in the weight unit price area AR14, it is shown that the weight unit price of "roast beef" is 420 yen. Further, in the product price area AR15, it is shown that the product price obtained by the weight of the product and the weight unit price is 1050 yen.
Further, in the clerk button display area AR20, the clerk button BT30 indicating "Taro", which is the clerk S, is continuously displayed from the time when the first "marinated salmon" is weighed. Further, on the clerk button BT30, the number "2" is displayed. This indicates that the product registered at this stage is the second one.

Here, when the weight adjustment of 250 g of "roast beef" is completed, the clerk confirms the registration of 250 g of "roast beef". However, in this case, since the third and subsequent products have not been ordered, the weighing of all the products ordered at this stage is completed. Therefore, the clerk in this case performs a subtotal operation by operating a predetermined button or the like. As described above, the subtotal operation may be performed as an operation for the "subtotal" button BT22 arranged on the product registration screens of FIGS. 5 to 7. Alternatively, the operation may be performed on the "subtotal" key as a mechanical key provided as a part of the key operation unit 108 of the registration settlement device 10. In response to the subtotal operation, the display on the clerk display unit 105 is changed from the conventional product registration screen to the subplanning surface.
The registration settlement device 10 may recognize the operation on the clerk button BT30 performed after the completion of product registration as a subtotal operation, and display the subplanning surface.

FIG. 8 shows an example of a subplanning surface displayed in response to the above subtotal operation. As shown in the figure, in the area showing "additional information", the registered contents of "marinated salmon" and "roast beef" registered by this product registration operation are shown. Specifically, the product name, weight, weight unit price, product price, etc. are shown for each registered product.
In terms of sub-planning, the total subtotal amount of "marinated salmon" and "roast beef" is 1846 yen, and the tax amount is 148 yen (example of tax rate 8%), and the subtotal amount and tax amount are combined. The total amount is shown to be 1994 yen.

The clerk S confirms the sub-planning aspect of the figure and informs the customer C of the amount of the price. In the case of cash payment, customer C hands the clerk S more money than the price. The clerk S inputs the amount of the delivered price as a deposit into the registration settlement device 10 and performs the current accounting operation. For example, the subplanning plane transitions to the current planning plane (not shown) according to the current total operation. On the current planning side, each amount such as total amount, deposit, change, etc. is displayed. When change occurs, the clerk takes out the amount of money from the drawer and hands it to customer C as change. In addition, the clerk S can make a payment in response to the use of, for example, a credit card, a prepaid card, or a cash voucher.

As described above, the registration settlement device 10 of the present embodiment sets the clerk indicated by the clerk information acquired from the clerk identification tag 30 having the strongest reception strength among the communicable clerk identification tags 30 as the handler. To do. That is, the registration settlement device 10 sets the clerk who is most likely to operate himself / herself to perform accounting as the handler. Then, the clerk button BT30 of the clerk set as the handler is displayed.
For example, when all the clerk buttons for each clerk in charge of sales at the store are displayed and the clerk is set to set the handler by operating his / her own clerk button, a certain limited area on the screen. Since a large number of clerk buttons are displayed on the screen, the size of each button becomes small and it is difficult to operate.
On the other hand, in the case of the present embodiment, one clerk button BT30 corresponding to one clerk set as the handler as described above may be displayed. Further, the clerk button BT30 can be displayed in a large size as shown in FIG. 6 and the like. As a result, in the present embodiment, it is possible to prevent accidentally operating a clerk button of a clerk different from oneself.

Then, in the present embodiment, the display of the clerk button BT30 is not displayed immediately after communication with the clerk identification tag 30, but the clerk measures the weight of the first product in one transaction. Is displayed when you start. In other words, the registration settlement device 10 is almost certain to perform accounting when the clerk, who was presumed to be most likely to operate himself / herself to perform accounting, actually begins to handle the product. The clerk button BT30 is displayed at the timing when it is found that the item has been checked. As a result, it is possible to avoid as much as possible a situation in which the clerk indicated by the displayed clerk button BT30 and the clerk who actually operates the registration settlement device 10 to perform accounting are different.

An example of a processing procedure executed by the registration settlement device 10 of the present embodiment will be described with reference to the flowcharts of FIGS. 9 to 12.
FIG. 9 shows a procedure example of a process (handler setting process) executed by the registration settlement device 10 regarding the setting of the handler. The process shown in the figure is periodically executed at regular intervals.
Step S101: The registration settlement device 10 determines whether or not there is one or more clerk identification tags 30 that can be communicated at present.
Step S102: When there is a clerk identification tag 30 capable of communicating, the registration settlement device 10 acquires clerk information from the clerk identification tag 30 at the timing when communication with the clerk identification tag 30 becomes possible. Therefore, the registration settlement device 10 selects the clerk information (an example of the clerk identification information) of the clerk identification tag 30 having the highest reception strength from the acquired clerk information.
Step S103: In the registration settlement device 10, whether or not the clerk indicated by the clerk information selected in step S102 is different (changed) from the clerk indicated by the clerk information currently set as the handler information. Judge about. The clerk information includes a clerk identifier uniquely indicating the clerk and a clerk name associated with the clerk identifier. Therefore, in the registration settlement device 10, as the process of step S103, the clerk identifier indicated by the clerk information selected in step S102 is different from the clerk identifier indicated by the clerk information currently set as the handler information, or It suffices to judge whether they match.
When it is determined in step S103 that the clerk indicated by the clerk information is the same, the same clerk as in the previous handler setting process is performing the accounting. In this case, since it is not necessary to change the handler information, the process shown in the figure is terminated.

Step S104: When it is determined in step S103 that the clerk indicated by the clerk information is different, the registration settlement device 10 performs a process of acquiring unfinished product registration information about the clerk indicated by the clerk information selected in step S102. Run.

The process of step S104 is a process related to the transfer of product registration. The unfinished product registration information is information indicating a registered product in one transaction for which settlement has not been completed yet.
Here, the registration of the "marinated salmon" illustrated in FIGS. 5 and 6 is performed by one registration settlement device 10-1, and the registration of the next "roast beef" shown in FIG. 7 is the registration settlement. The product registration takeover using the unfinished product registration information will be described by taking the case of the device 10-3 as an example.
In this case, first, in response to the registration of "marinated salmon", the registration settlement device 10-1 includes the product registration information about "marinated salmon", and the clerk "Taro" acts as the handler. Generates the associated unfinished product registration information and stores the generated unfinished product registration information.
After this, the clerk "Taro" moves to the registration settlement device 10-3 near the "roast beef" and weighs the registration settlement device 10-3 for the registration of the "roast beef". .. At this time, the registration settlement device 10-3 proceeds to step S104 through the processes of steps S101 to S103. In this case, the registered settlement device 10-3 specifies another registered settlement device 10-1, 10-2 in step S104 by designating the clerk identifier indicated by the clerk information of the clerk "Taro" selected in step S102. Request unfinished product registration information.
In this case, the registration settlement device 10-1 stores the unfinished product registration information corresponding to the clerk "Taro". Therefore, the registration settlement device 10-1 responds to the request and transmits the unfinished product registration information to the registration settlement device 10-3. The registration settlement device 10-3 can perform the product registration process by adding the roast beef registration to the received unfinished product registration information in response to the registration of the "roast beef". In this way, the product registration takeover is realized in the present embodiment.
If the clerk of the clerk information selected in step S102 is going to register the first product in one transaction, there is no corresponding unfinished product registration information. In this case, the unfinished product registration information is not acquired by step S104.

Step S105: The registration settlement device 10 registers the clerk information selected in step S102 as the handler information indicating its own handler. In this case, if there is no handler information, the handler information is newly registered, and if the clerk information of a different clerk is previously registered as the handler information, the handler information is updated. become.
Further, when the unfinished product registration information is acquired in step S104, the acquired unfinished product registration information is associated with the handler information.

Step S106: On the other hand, when it is determined in step S101 that there is no clerk identification tag 30 that can communicate, the registration settlement device 10 determines whether or not the handler information is registered.
Step S107: When the handler information is registered, the handler information is registered according to the presence of the clerk identification tag 30 that can communicate with the registration settlement device 10 at the timing of the previous handler setting process. However, at this timing, the clerk identification tag 30 that can communicate with the registration settlement device 10 has disappeared. That is, the state has changed from the state in which at least one clerk S has been present near the registered settlement device 10 to the state in which no one has disappeared. Therefore, in this case, the handler information registered so far is deleted.
On the other hand, when it is determined in step S106 that the handler information is not registered, there is no clerk identification tag 30 that can communicate even in the previous handler setting process (that is, near the registration settlement device 10). There was no clerk). In this case, step S107 is skipped and the process shown in the figure ends.

FIG. 10 shows an example of a processing procedure executed by the registration settlement device 10 regarding the display of the clerk button BT30.
Step S201: The registration settlement device 10 is waiting for the first product designation operation to be registered after the registration of the handler information in step S105 of FIG. 9 is performed. The first product designation operation to be registered after the handler information is registered is one of the following two cases. One is the case where the first product designation operation in one transaction is performed. The other is that one or more products have already been registered in one transaction, but by taking over the product registration, the clerk can perform the next registration target product specification operation in the same transaction for a different registration settlement. This is the case when the device 10 is used.

Step S202: In response to the product designation operation, the registration settlement device 10 displays the information of the product designated as the registration target on the product registration screen. Specifically, as illustrated in FIG. 5, information such as the product number, product name, and weight unit price of the product designated as the registration target is displayed. These information can be obtained from the product master stored in the registration settlement device 10.

Step S203: After displaying the information of the product designated as the registration target as described above, the registration settlement device 10 waits for the measurement of the product designated as the registration target to start. Whether or not the measurement has been started can be determined by whether or not the value of the weight measured by the measuring unit 109 has started to fluctuate from a stable state without fluctuation.
Step S204: When it is determined in step S203 that the weighing has been started, the registration settlement device 10 starts displaying the clerk button BT30 corresponding to the clerk information registered as the handler information in step S105 of FIG.

Step S205: After displaying the clerk button BT30 in step S204, the registration settlement device 10 waits for the clerk button BT30 to be operated.
Step S206: In response to the operation on the clerk button BT30, the registration settlement device 10 performs a process of determining the clerk corresponding to the clerk button BT30 displayed in step S204 as the handler (handler confirmation process). Run. As a specific process for this purpose, for example, the registration settlement device 10 manages the handler confirmation flag indicating whether or not the handler is confirmed in association with the handler information, and confirms the handler as the handler. Depending on what has been done, a value indicating confirmation may be stored for the handler confirmation flag. By being confirmed as the handler, the clerk can register the product by the registration settlement device 10. If the product registration operation is advanced without operating the displayed clerk button BT30, for example, an error occurs at the stage of the product registration confirmation operation, and the registration settlement device 10 outputs a message prompting the operation of the clerk button BT30. ..
The clerk as the handler determined in step S206 is released from the determination when, for example, the settlement process of the corresponding transaction is completed. In canceling the confirmation, for example, the above-mentioned handler confirmation flag may be changed to a value indicating that the confirmation is undecided.

In the embodiment in which one clerk button BT30 is displayed as in the present embodiment, after the clerk button BT30 is displayed in step S205 instead of the process of waiting for the operation of the clerk button BT30. It may be determined whether or not a certain time (about several seconds) has elapsed without the cancel operation being performed. The cancel operation here is, for example, an operation for instructing that the displayed clerk button BT30 is not the actual operator. That is, instead of confirming the handler set according to the operation of the clerk button BT30, the handling is performed after a certain period of time has passed without the cancel operation being performed after the clerk button BT30 is displayed. You may try to determine the person. When the cancel operation is performed, the registration settlement device 10 may switch to the display of the clerk button BT30 corresponding to the clerk identification tag 30 having the next highest reception strength.

FIG. 11 shows an example of a processing procedure executed by the registration settlement device 10 regarding the erasure of the clerk button BT30.
Step S301: The registration settlement device 10 determines whether or not the handler information has been changed. Regarding whether or not the handler information has been changed, the registration settlement device 10 may determine whether or not any of the processes of step S105 and step S107 of FIG. 9 has been performed.
Step S302: When it is determined in step S301 that the handler information has been changed, the registration settlement device 10 determines whether or not the clerk button BT30 is being displayed at the timing when the handler information is changed.

Step S303: If it is determined in step S301 that there is no change in the handler information, the registered settlement device 10 further determines whether or not the confirmation of the clerk as the handler has been canceled according to the completion of the settlement process. Judge about.

Step S304: When it is determined in step S302 that the display is being performed, the clerk button BT30 that is displayed is the clerk button BT30 corresponding to the clerk registered in the handler information before the change. When it is determined in step S105 that the handler information is changed, the clerk closest to the registered settlement device 10 is replaced by the clerk registered in the changed handler information, or the registered settlement device. The situation is that there are no clerk near 10. In such a situation, it is possible to take the idea that it is no longer necessary to display the clerk button for the clerk registered in the handler information before the change.
Further, at the stage when the settlement process is completed and the determination of the clerk as the handler is canceled in step S303, the clerk button BT30 corresponding to the clerk registered as the handler so far is displayed. In this case as well, it is possible to adopt the idea that it is not necessary to continuously display the clerk button BT30 after the settlement process is completed.
Therefore, when it is determined in step S302 that the clerk button BT30 is being displayed as described above, or when the confirmation of the clerk as the handler is canceled in step S303, the registration settlement device 10 has been displayed so far. Erase the clerk button BT30 that was allowed to do so.

If it is determined in step S302 that the clerk button BT30 is not being displayed, the handler information has been changed, but the first weighing has not yet been started, and the clerk button BT30 is displayed. Not. Therefore, in this case, step S304 is skipped, and the process shown in the figure is terminated.

Further, when it is determined in step S303 that the determination of the clerk as the handler has not been released, one of the following two states corresponds. One is a state in which weighing has not yet started since the information was changed to the current handler information, and the clerk button BT30 has not yet been displayed. Alternatively, the clerk button BT30 is displayed in response to the start of weighing, but the clerk button BT30 is not touched. In the former case, since the clerk button BT30 is not displayed, it cannot be deleted. In the latter case, the situation is not such that the clerk button BT30 should be erased. Therefore, if it is determined in step S303 that the determination of the clerk as the handler has not been released, the registration settlement device 10 skips step S304 and ends the process of the figure.

<Second Embodiment>
Subsequently, the second embodiment will be described. In the first embodiment, for example, when the clerk S moves to another registered settlement device 10 after completing the product registration with one registration settlement device 10 for taking over the product registration, the step of FIG. 11 The processes of S301, S302, and S304 are executed. By these processes, the clerk button BT30 corresponding to the clerk S displayed on the registration settlement device 10 before the movement cannot communicate with the corresponding clerk identification tag 30, and the handler information is changed. Will be erased accordingly. With such a configuration, in the present embodiment, when the clerk S moves between the registered settlement devices 10 in response to the product registration takeover, the clerk button BT30 corresponding to the same clerk S is displayed on the plurality of registered settlement devices 10. It is designed so that it will not be displayed at the same time.
On the other hand, in the present embodiment, even if the clerk S moves to another registration settlement device 10 to take over the product registration and communication with the corresponding clerk identification tag 30 becomes impossible, it is displayed so far. The display of the clerk button BT30 corresponding to the clerk S that had been there is not immediately erased. The clerk button BT30 displayed on the registered settlement device 10 that was operated before the clerk S moved is deleted when the same clerk S is confirmed as the handler in the registered settlement device 10 after the move. .. In such an embodiment, for example, until the clerk S is confirmed as the handler by the registered settlement device 10 after the move, the clerk button BT30 of the clerk S on the registered settlement device 10 before the move is displayed. Will be maintained. Even in such a display mode, the clerk button BT30 corresponding to the same clerk S is not displayed at the same time on the plurality of registered settlement devices 10.

The handler setting process by the registration settlement device 10 and the process related to the display of the clerk button BT30 in the present embodiment may be the same as those in FIGS. 9 and 10, respectively.
Then, the registration settlement device 10 in the present embodiment executes the processing procedure related to the display of the clerk button BT30 as shown in the flowchart of FIG. 12 as follows. In the figure, the steps that are the same as those in FIG. 10 are designated by the same reference numerals and the description thereof will be omitted.
Step S207: The registration settlement device 10 sends a handler confirmation notification to another registration settlement device 10 to notify that the clerk as the handler has been newly confirmed in response to the execution of the handler confirmation process in step S206. Send to. The handler confirmation notification includes the clerk identifier of the clerk who has been confirmed as the handler.

FIG. 13 shows an example of a processing procedure executed by the registration settlement device 10 in the present embodiment regarding the erasure of the clerk button BT30.
Step S401: The registered settlement device 10 determines whether or not the handler confirmation notification transmitted from the other registered settlement device 10 has been received.
Step S402: When the registration settlement device 10 receives the clerk confirmation notification, if the clerk button BT30 is currently being displayed, the clerk button BT30 received in step S401 is the clerk button BT30 being displayed. It is determined whether or not the clerk corresponding to is a notification that the clerk has been confirmed as the handler. For this purpose, the registration settlement device 10 determines whether or not, for example, the clerk indicated by the clerk identifier included in the handler confirmation notification and the clerk indicated by the clerk information corresponding to the displayed clerk button BT30 match. Just do it. In the present embodiment, the clerk information corresponding to the displayed clerk button BT 30 may be stored without being deleted even if communication with the corresponding clerk identification tag 30 becomes impossible, for example.
Step S403: Further, when the registration settlement device 10 determines in step S401 that the handler confirmation notification is not received, it further determines whether or not the handler confirmation has been canceled according to the end of the settlement process. ..

Step S404: In step S402, when it is determined that the handler confirmation notification received in step S401 is for the clerk corresponding to the clerk button BT30 being displayed, it corresponds to the clerk button BT30 being displayed. The clerk has moved to another registration settlement device 10 and has begun operations related to product registration. Therefore, the registration settlement device 10 in this case erases the clerk button BT30 that has been displayed so far.
Further, even when it is determined in step S403 that the settlement process is completed and the determination of the clerk as the handler is canceled, the clerk button is continuously pressed as in the case of the previous step S303 (FIG. 11). There is no need to display the BT30. Therefore, also in this case, the registration settlement device 10 erases the clerk button BT30 that has been displayed so far.

In step S403, the case where a negative determination result is obtained means that the clerk button BT30 is not being displayed, or even if the clerk button BT30 is being displayed, the clerk button BT30 indicating the clerk indicated by the received handler confirmation notification. This is the case when it is determined that there is no such thing. In the former case, the clerk button BT30 to be erased is not displayed. Further, in the latter case, since the clerk button BT30 for the clerk who is still performing the accounting operation (the settlement process has not been completed) is displayed, it is necessary to delete the clerk button BT30. There is no. Therefore, in these cases, the registration settlement device 10 skips step S404 and ends the process of the figure.
Further, when it is determined in step S403 that the determination of the clerk as the handler has not been released, and if there is a clerk button BT30 being displayed, the settlement corresponding to the clerk indicated by the clerk button BT30 is made. Since the process has not been completed, it is not a situation that should be deleted. Therefore, also in this case, the registration settlement device 10 skips step S404 and ends the process of the figure.

<Third Embodiment>
Subsequently, the third embodiment will be described. In the description of the embodiments so far, one clerk button BT30 indicating the clerk corresponding to the clerk identification tag 30 having the highest reception strength among the clerk identification tags 30 in a communicable state is displayed. On the other hand, in the present embodiment, a plurality of clerk buttons BT30 are displayed depending on the number of clerk identification tags 30 in a communicable state. Specifically, in the present embodiment, the clerk button BT30 for the clerk corresponding to all of the communicable clerk identification tags 30 is displayed.

FIG. 14 shows an example of a product registration screen in a state where the clerk button BT30 is displayed under the present embodiment. In the clerk button display area AR20 on the product registration screen shown in the figure, the clerk button BT30 is the clerk button BT30-1 indicating the clerk named "Taro", and the clerk button BT30 is the clerk indicating the clerk named "Jiro". The state in which the button BT30-2 and the button BT30-2 are arranged is shown. The clerk button BT30 (BT30-1, BT30-2) on the product registration screen in the figure is displayed at the timing when the first weighing of the product is started, for example, as in the case of each of the above embodiments. Is.
In the state where the two clerk buttons BT30 (BT30-1, BT30-2) are displayed in this way, the clerk identification tags 30 of the two clerk "Taro" and "Jiro" are displayed at the timing when the weighing is started. Indicates that is in a state of being able to communicate with the registration settlement device 10. That is, it indicates that two clerk, "Taro" and "Jiro", are near the registration settlement device 10. In this case, the clerk who actually performed the weighing operation is either "Taro" or "Jiro". That is, in the present embodiment, the clerk button BT30 indicating the clerk as a candidate for the handler is displayed according to the start of weighing.

Then, the clerk who actually operates the registration settlement device 10 to perform accounting operates the clerk button BT30 of the clerk corresponding to himself / herself from the displayed clerk button BT30, and he / she handles the registration settlement device 10. Confirm that you are a person.
Specifically, when the clerk "Jiro" is the clerk who performs the accounting, the clerk "Jiro" places the "marinated salmon" on the scale 109a and weighs it. The clerk "Jiro" looks at the clerk buttons BT30-1 and BT30-2 displayed at the timing when the "marinated salmon" is weighed. Then, after confirming that the clerk button BT30-2 corresponds to the clerk button BT30-2, the clerk "Jiro" operates the clerk button BT30-2 to confirm that he / she is the operator of the registration settlement device 10. determine.

For example, when one clerk button BT30 corresponding to the clerk identification tag 30 having the highest reception strength is displayed, the clerk who performed the weighing operation depends on the positional relationship between the registered settlement device 10 and the clerk at that time. Instead, there is a possibility that the clerk button BT30 of the clerk who happened to be near the registration settlement device 10 is displayed.
Therefore, as in the present embodiment, by displaying the clerk button BT30 of a plurality of clerk corresponding to each clerk identification tag 30 capable of communicating with the registration settlement device 10, the clerk button BT30 of the clerk who performed the weighing operation is displayed. Is displayed more reliably.
In this case, the clerk who has performed the weighing selects the clerk button BT30 corresponding to himself / herself from the plurality of clerk button BT30s to perform the operation in order to determine the handler. However, in the operation of the registered settlement device 10 in the present embodiment, there is a possibility that the clerk identification tag 30 may approach one registered settlement device 10 at the same time so as to be able to communicate with the registered settlement device 10. The number of clerk is about a few. Therefore, even when displaying a plurality of clerk buttons BT30, the size of the clerk button BT30 is the same as when displaying one, or even if the size is reduced, it does not become extremely small, and to some extent. Can maintain the size of. As a result, it is unlikely that the clerk mistakenly operates the clerk button BT30 corresponding to other than himself / herself.

In addition, various arrangements can be considered when displaying a plurality of clerk buttons BT30. For example, the order of arrangement of the clerk buttons BT30 based on the number as the clerk identifier shown in the clerk information may be used. As a specific example, the clerk button display area AR20 may be arranged in ascending order from the top to the bottom of the number as the clerk identifier.
In addition, for example, it may be displayed in the order of arrangement based on the order of the highest reception strength with the corresponding clerk identification tag 30.

In the above example, the clerk button BT30 corresponding to all the clerk identification tags 30 in a state of being able to communicate with the registration settlement device 10 is displayed. However, for example, among the clerk identification tags 30 that are in a state of being able to communicate with the registration settlement device 10, the clerk corresponding to a predetermined plurality (for example, about two) of the clerk identification tags 30 selected in descending order of reception strength. The button BT30 may be displayed.
Further, for each of the plurality of displayed clerk button BT30s, a predetermined mode may be provided in which the reception strength with the clerk identification tag 30 is shown.

In each of the above embodiments, the display of the clerk button BT30 is started at the timing when the measurement of the product is started by the registration settlement device 10. However, the registration settlement device 10 may display the clerk button BT30 at the timing when it is determined that the numerical value to be measured is stable after the measurement is started.

As a modification of the sales system of the present embodiment, a plurality of registration devices (an example of a product sales data processing device) and one or more settlement devices may be communicably connected to each other. The registration device has a configuration in which the function of the settlement process is omitted from the registration settlement device 10. When the registration device completes the registration of the product corresponding to one transaction, the registration device transmits the settlement information used for the settlement of the registered product to the settlement device. Customers who have completed product registration with the registration device move to the checkout device. The clerk who operates the settlement device causes the settlement device to execute the settlement process using the transmitted settlement information.
Even in the configuration of such a sales system, the configuration of the registration settlement device 10 in each of the above embodiments may be applied to the registration device.
