The store information server includes a list of product items sold at the store in the available store information for each store. In response to receiving the available store search request, the store information server determines the presence or absence of products registered in the shopping list for each available store information searched as being within a certain range from the location of the mobile terminal device 40. The available store information is transmitted to the mobile terminal device 40, including the information shown. In this case, the mobile terminal device 40 may display available stores on the map so that the presence or absence of products registered in the shopping list can be visually confirmed. As a display format of available stores that allows you to visually confirm the presence or absence of products registered in the shopping list, for example, regarding the mark indicating available stores, available stores with and without products registered in the shopping list are displayed. The color coding and size may be changed depending on the available stores.

In addition, when the customer performs an operation to select an arbitrary store mark (for example, a tap operation on the mark) while the surrounding store information screen is displayed as shown in FIG. 9(B), the As shown in 9(C), a store information screen showing information on the selected store is displayed.

As described above, on the startup screen shown in FIG. 9(A), a "notification" button and a "value information" button are arranged. Also, on the store information screen in FIG. 9(C), a "notification" button and a "bargain information" button are arranged.
If the customer operates the "Notification" button while the startup screen or store information screen is displayed, the corresponding available stores will be displayed as "Notification", as shown in Figure 10(A). An advertising screen will be displayed that provides information on events, sale announcements, etc. prepared as follows.
Additionally, when the customer operates the "Special Offer" button, an advertisement screen is displayed that provides information on services such as discounts for customers using the shopping application, as shown in Figure 10(B). be done.
The display of these advertisement screens may be performed based on advertisement information included in the available store information transmitted from the store information server.

Further, when the shopping start button arranged on the startup screen of FIG. 9(A) is operated, the touch panel display unit 406 displays the product registration screen (code scan screen) as shown in FIG. 10(C). Transition. The customer can perform a product registration operation using the mobile terminal device 40 on which the product registration screen is displayed.

Here, as an example of a basic product registration operation, an example of a product registration operation at a sales floor where product shelves are arranged will be described, not at a sales floor where the weighing and pricing device 10 is arranged.
For example, a customer takes out a product that he or she wants to purchase (product to be purchased) from a product shelf. The customer receives the code information of the code (barcode, but may also be a two-dimensional code) attached to the product to be purchased, using the imaging unit of the mobile terminal device 40 with the product registration screen displayed. 408 performs a reading operation.
The code information read in this manner is transmitted from the mobile terminal device 40 to the transaction management server 50 as product registration information corresponding to one product. The transaction management server 50 includes the received product registration information in cart information (payment information) corresponding to one transaction. Further, product registration information based on the read code information may be stored in the mobile terminal device 40.
After completing the registration operation for all the products to be purchased, the customer performs a predetermined operation (product registration completion operation) on the mobile terminal device 40 to instruct completion of product registration. When the product registration completion operation is performed, the mobile terminal device 40 may notify the transaction management server 50 of the completion of product registration. The transaction management server 50 that has received the notification of product registration completion can manage the cart information of the corresponding transaction as if the product registration has been completed.

When the product registration completion operation is performed, a payment guidance screen is displayed on the touch panel display unit 406 of the mobile terminal device 40, as shown in FIG. 10(D). The payment guidance screen shown in the same figure contains, for example, two messages for the customer, instructing them to go to the payment device 20 for payment, and transaction code information indicating the transaction corresponding to the current product registration. Displayed as a dimension code. The transaction code information includes a transaction identifier that uniquely indicates the transaction. This transaction identifier is, for example, issued by the transaction management server 50 in response to the mobile terminal device 40 first transmitting product registration information in a corresponding transaction, and is notified to the mobile terminal device 40. good.
The customer goes to the payment device 20 and causes the scanner section 204 of the payment device 20 to read the two-dimensional code displayed on the payment guidance screen. The payment device 20 acquires cart information corresponding to the transaction identifier indicated by the read two-dimensional code from the transaction management server 50. The payment device 20 uses the acquired cart information to execute payment processing according to the customer's operations. Note that the payment device 20 includes one or more card readers corresponding to predetermined cards, for example, when a customer uses or uses cards such as a credit card, an electronic money card, and a point card to perform payment. may be provided.
In this manner, in this embodiment, a customer who has installed the shopping application on his or her own mobile terminal device 40 can register a product by operating his or her own mobile terminal device 40 . Further, the payment on the payment device 20 is also performed by the customer's operation. Since product registration and payment are performed by the customer in this manner, in this embodiment, there is no need for the store clerk to perform product registration operations, operation of the payment device, etc.

On the other hand, in some stores, there is a sales section that allows customers to sell products by weight using a weighing and pricing device 10 and registering the products by self-service. In such a department that supports selling by weight, the procedure for product registration and the associated processing in the sales system are based on the basics explained above in a department where such a weighing and pricing device 10 that is compatible with a self-service method is used. This is different from when a product registration operation is performed. This point will be explained below.

First, an example of a procedure for product registration by a customer at a sales floor where the weighing and pricing device 10 is used will be described.
When a customer wants to purchase a product sold by weight, the customer first uses his or her mobile terminal device 40 to input the item of the product to be purchased as follows.
FIG. 11 shows an example of how products sold by weight are displayed in a store. In the example shown in the figure, lemon LM, apple AP, and orange OG are displayed as products sold by weight. Additionally, product information panels 3000-LM, 3000-AP, and 3000-OG are installed corresponding to the displayed lemons LM, apples AP, and oranges OG. Product information panels 3000-LM, 3000-AP, and 3000-OG are referred to as product information panel 3000 unless they are particularly distinguished.

The product information panel 3000 presents information on the corresponding product. In the figure, the product information panel 3000-LM is shown enlarged. In this manner, the product information panel 3000-LM presents the product information that the product item is lemon, the unit price per unit weight, and the product information code 3001. In the example shown in the figure, the product information code 3001 is a barcode (one-dimensional code). The product information code 3001 includes the product code of the product item as a lemon.
Similarly, in other product information panels 3000, the product item, unit price per unit weight, and product information code are presented as product information.

The product information panel 3000 may be configured to present product information through display by a display device. Alternatively, the product information panel 3000 may present product information by pasting a printed matter such as a poster.
By presenting product information using a display device, it is possible to display a display that reflects discounts during time service, etc., at an appropriate timing. Additionally, by changing and displaying barcodes as time passes, and by having the mobile terminal device 40 read barcodes captured in advance by a camera, products sold by weight can be registered at different unit prices. It is possible to prevent such fraud.

In order to input the item of the product to be purchased, the customer displays the product registration screen on his/her mobile terminal device 40 and inputs the product information code presented on the product information panel 3000 of the product to be purchased into the mobile terminal device. Let 40 read it. In the figure, a customer is shown reading a product information code 3001 corresponding to lemon LM. A scanned image area AR11 on the product registration screen of the mobile terminal device 40 shows an image of the product information code 3001.
When the product information code 3001 corresponding to lemon LM is code scanned in this way, the mobile terminal device 40 acquires the product information of lemon LM from the read product information code 3001. The mobile terminal device 40 uses the acquired product information to designate lemon LM as an item of the product sold by weight.

Further, on the product registration screen, a product registration status area AR12 is arranged. The product registration status area AR12 shows the current registration status of the product to be purchased. In the figure, in the product registration status area AR12, a total area AR121 and registration list items AR122 (AR122-1, AR122-2, AR122-3) are arranged. The registration list item AR122 is a list item that individually indicates registered products or products in a temporarily registered state for which the item has been input.
In the figure, as the registration list item AR122, registration list items AR122-1, AR122-2, and AR122-3 corresponding to yogurt, apple AP, and lemon LM are arranged.
In this case, yogurt is not a product sold by weight. Therefore, in the yogurt registration list item AR122-1, the comment display commercial displays "x1", indicating that one item has been registered, and also indicates that the price is 160 yen. There is.
On the other hand, for the apple AP and lemon LM products sold by weight, the products to be purchased are in a "temporary registration" state (temporary registration state). A product in a provisionally registered state is a product for which the item has been entered but pricing has not yet been completed (it is also in a state of waiting for weighing).
Therefore, in the registered list items of Apple AP and Lemon LM, for example, a comment displaying CM saying "weighing required" indicates that pricing by weighing has not yet been performed. Accordingly, in the registered list items of Apple AP and Lemon LM, "?? Yen" is displayed to indicate that the price is undetermined. Further, in the registration list items AR122-1 and AR122-2, a predetermined background color indicating the temporary registration state is set.

In the example shown in the figure, the customer has temporarily registered lemon LM and apple AP as products sold by weight. In this case, there were two types of bulk products that the customer specified for purchase: lemons LM and apples AP. In this case, the customer weighs the lemon LM and the apple AP, respectively. Therefore, the customer takes out the quantity (number) of the lemons LM and apples AP that he or she wishes to purchase from the displayed lemons LM and apples AP. Then, the customer takes the lemon LM and apple AP with him and goes to the weighing and pricing device 10.

The weighing and pricing device 10 that the customer went to was not operating in response to operations by other customers, so it was in a standby mode waiting for the start of weighing in response to one transaction. Ta. The weighing and pricing apparatus 10 in standby mode displays an initial pricing operation screen on the customer display unit 106.

FIG. 12 shows an example of an initial pricing operation screen displayed on the customer display section 106.
In the pricing operation screen shown in the figure, a weighing result area AR31 is arranged. The weighing result area AR31 is an area (column) in which the weighing results of the sold-by-weight products to be priced are displayed. The weighing result area AR31 includes a weight area AR31-1, a weight unit price area AR31-2, and a total price area AR31-3.
The weight area AR31-1 is an area where the measured weight of the sold-by-weight product to be priced is shown.
The weight unit price area AR31-2 is an area where the weight unit price of the sold-by-weight product to be priced is shown.

Note that some products sold by weight are sold in quantity, where the number is calculated based on the measured weight and unit weight, and the price is calculated based on the calculated number and the unit price per item. . In the case of such a product sold by weight, the weight area AR31-1 displays the number calculated based on the measured weight and unit weight, and the weight unit price area AR31-2 displays the number of pieces calculated based on the measured weight and unit weight. The unit price per piece may be indicated.
The total price area AR31-3 is an area where the total price of the sold-by-weight products whose prices have been completed so far under the same transaction is shown.

The product selection area AR32 is an area where a product to be priced can be selected. In the product selection area AR32 in the figure, four tabs TB (TB-1 to TB-4) are arranged in the product selection area AR32. In the product selection area AR32, each tab TB is associated with a sheet on which product buttons are arranged. The tab TB can be selected by the customer's operation. The selected tab TB is highlighted with respect to other tabs TB, and the product button BT1 arranged on the sheet of the selected tab TB is displayed in the product selection area AR32.

In the example shown in the figure, a product button BT1 for a temporarily registered product is arranged on the sheet corresponding to the tab TB-1.
On the sheet corresponding to tab TB-2, product buttons BT1 (preset keys) for each product registered in advance in the product master according to the classification of sold-by-weight products are arranged in a predetermined order.
In the sheet corresponding to tab TB-3, product buttons for products classified as fruits are further arranged based on the classification of sold-by-weight products in the product master.
The sheet corresponding to tab TB-4 is a tab corresponding to a sheet on which product buttons for products further classified as vegetables are arranged under the category of sold-by-weight products in the product master.
In this case, fruit sheets and vegetable sheets are prepared in accordance with the fact that fruit and vegetable products have a high purchase history among the products sold by weight.

In the initial state of the pricing operation screen, tab TB-2 is selected, as shown in the figure. As a result, in the product selection area AR32, product buttons BT1 of products included in the general product category registered in the product master under the classification of sold-by-weight products are arranged on the sheet corresponding to the tab TB-2.
In this case, the arrangement order of the product buttons BT1 on the sheet may be determined based on, for example, purchase history or a preset priority order. Furthermore, in the product selection area AR32 in the figure, 16 product buttons BT1 are arranged. In other words, 16 products sold by weight are presented as selection candidates. If there are 17 or more products registered in the category of sold-by-weight products, product buttons BT1 for other sold-by-weight products can be displayed by, for example, paging or scrolling the area of the sheet.
In addition, in the same figure, product information is shown in simplified form such as "Item1" and "Item2" in the product button BT1. may be displayed.
The sheet corresponding to tab TB-2 is an area for specifying (selecting) a product to be priced from among all products classified as bulk products by the product master.

The sheet corresponding to tab TB-2 is an area where a customer who bids on a sold-by-weight product without using the mobile terminal device 40 performs an operation to select a sold-by-weight product to price.
In the case of a customer who prices a product sold by weight without using the mobile terminal device 40, information on the temporarily registered product sold by weight cannot be obtained from the mobile terminal device 40. In this case, the customer finds a product button BT1 corresponding to the bulk product to be purchased taken from a place where bulk products are displayed from the sheet corresponding to the tab TB-2, and operates the found product button BT1. At this time, the customer who does not use the mobile terminal device 40 for product registration specifies the item of the product to be priced by operating the product button BT1 on the sheet of tab TB-2.

If the sold-by-weight product to be purchased is fruit, the customer who does not use the mobile terminal device 40 to register the product operates tab TB-3 to display a sheet on which product buttons BT1 for sold-by-weight products in the fruit category are arranged. can be done. The customer can specify the product item to be priced by operating the product button BT1 corresponding to the bulk product to be purchased from among the product buttons BT1 arranged on the displayed sheet.
In addition, when the sold-by-weight product to be purchased is vegetables, the customer who does not use the mobile terminal device 40 to register the product can operate the tab TB-4 to select the sheet on which the product button BT1 for the sold-by-weight product in the category of vegetables is arranged. can be displayed. The customer can specify the product item to be priced by operating the product button BT1 corresponding to the bulk product to be purchased from among the product buttons BT1 arranged on the displayed sheet.

Furthermore, a message area ARm is arranged above the product selection area AR32. The message area ARm is an area where a message with predetermined content corresponding to the content of the current screen is displayed. In the message area ARm in the figure, "Select The Item" is displayed. That is, in this case, the message area ARm displays a message instructing the customer to operate the product button BT1 to specify the item of the product to be priced.

Further, in the pricing operation screen, a connection information code area AR34 is arranged. The connection information code area AR34 is an area where the connection information code CD is displayed. The connection information code may be displayed as a two-dimensional code, for example. The connection information code is control information indicating procedures for connecting the mobile terminal device 40 on which the shopping application operates to the weighing and pricing device 10 using, for example, Bluetooth.
In the connection information code area AR34, a message is displayed to guide the customer to read the connection information code CD into the mobile terminal device 40.

Further, on the pricing operation screen, a search area AR33 is arranged in which products sold by weight can be searched for by character input operation. In the example shown in the figure, it is possible to search for products sold by weight by operating a software keyboard arranged in the search area AR33 and inputting a product name, etc.
Note that the search area AR33 may not be arranged on the pricing operation screen. Then, for example, the search area AR33 may be displayed in response to a predetermined operation performed on the pricing operation screen.

A customer who uses the mobile terminal device 40 for product registration performs an operation to cause the mobile terminal device 40 to read the connection information code CD displayed in the connection information code area AR34 when starting the registration of the bulk product to be purchased.

The mobile terminal device 40 establishes communication with the weighing and pricing device 10 in response to reading the connection information code CD as described above. By communicatively connecting the weighing and pricing device 10 and the mobile terminal device 40 in this way, the weighing and pricing device 10 enters a state in which communications are exclusively used by the connected mobile terminal device 40. In the state where communication is exclusive, the mobile terminal device 40 does not connect with other mobile terminal devices 40.

Furthermore, if a customer who does not use the mobile terminal device 40 to register a product starts weighing by placing the product on the weighing platform 109b, the weighing and pricing device 10 uses the mobile terminal device 40 from then on. Establishment of mutual communication may be prohibited. If the establishment of mutual communication is not prohibited, even if an attempt is made to establish mutual communication, it will end in failure, but it will take time until the timeout occurs, so it is possible to actually measure after the above declaration is detected. It will take some time for this to happen. On the other hand, if the establishment of mutual communication is prohibited, unnecessary time (time before timeout) is saved and measurement can be performed immediately. Note that, for example, the above-mentioned prohibition may be canceled after printing of the label is completed.

When establishing mutual communication with the mobile terminal device 40 is prohibited as described above, the weighing and pricing device 10 may erase the previous display of the connection information code CD. In this case, in the connection information code area AR34 where the connection information code CD has been erased, a display may be made to indicate that establishment of communication with the mobile terminal device 40 is currently prohibited.
Alternatively, the connection information code CD in the connection information code area AR34 may be displayed at least in a grayed out manner to indicate that establishment of communication with the mobile terminal device 40 is currently prohibited. good.

In response to establishment of communication with the weighing and pricing device 10, the mobile terminal device 40 transmits information on the sold-by-weight product in the provisionally registered state to the weighing and pricing device 10. Specifically, the mobile terminal device 40 in this case transmits information on the lemon LM and the apple AP as information on the sold-by-weight products in the provisionally registered state.

The weighing and pricing device 10 changes the pricing operation screen to the mode shown in FIG. 12 to FIG. 13 in response to receiving information about the temporarily registered product sold by weight. In FIG. 13, the same parts as those in FIG. 12 are designated by the same reference numerals, and description thereof will be omitted as appropriate.

In the product selection area AR32 of the pricing operation screen in FIG. 13, tab TB-1 is selected instead of tab TB-1 that was selected in FIG. Two product buttons BT1 corresponding to apple AP and lemon LM are arranged on the sheet corresponding to the selected tab TB-1. The sold-by-weight products Apple AP and Lemon LM corresponding to the two product buttons BT1 are products that have been temporarily registered as described above with reference to FIG. 11.
That is, based on the information of the sold-by-weight product in the temporarily registered state received from the mobile terminal device 40, the mobile terminal device 40 displays a product button for the sold-by-weight product in the temporarily registered state in the product selection area AR32 on the sheet corresponding to the tab TB-1. Display BT1.
In this case, the arrangement order of the product buttons BT1 may correspond to the temporary registration order (the order in which the product information codes are read).

That is, the weighing and pricing device 10 receives information about the sold-by-weight product (temporarily registered product) in the provisionally registered state by establishing the connection with the mobile terminal device 40 in the standby mode. When the weighing and pricing device 10 receives the information on the temporarily registered product, if the sheet of tab TB-2 (Fig. 12) is displayed on the initial pricing operation screen, the weighing and pricing device 10 displays the product as the temporarily registered product. The display is switched to the sheet of tab TB-1 on which button BT1 is arranged (FIG. 13).
Such switching of the tab TB can be interpreted as emphasizing (prioritizing) and displaying temporarily registered products from among the products registered in advance in the product master by classification as products sold by weight.

Note that the manner in which temporarily registered products are displayed with emphasis (priority) is not limited to the example of switching sheets as described above.
For example, when the weighing and pricing device 10 has not received information on temporarily registered products, it displays a sheet with product buttons BT1 corresponding to all products sold by weight as shown in FIG. 12.
Then, when the information on the temporarily registered product is received, the weighing and pricing device 10 erases the product buttons BT1 other than the temporarily registered product from among the product buttons BT1 corresponding to all products sold by weight on the same sheet, and It may be displayed so that the product button BT1 of the registered product remains. At this time, the product buttons BT1 of the temporarily registered products may be rearranged so that they are all located together.
Alternatively, when the information on the temporarily registered product is received, the weighing and pricing device 10 displays the product button BT1 of the temporarily registered product so that the size is larger than the product button BT1 of the product that is not in the temporarily registered state. It's fine.
Alternatively, when the information on the temporarily registered product is received, the weighing and pricing device 10 determines that in the product selection area AR32, the area where the product button BT1 of the temporarily registered product is arranged and the product button BT1 of the product that is not the temporarily registered product are arranged. It may be displayed separately from the area where it is placed.
Furthermore, the manner in which the product button BT1 of the temporarily registered product is emphasized with respect to the product button BT1 of the product that is not in the temporarily registered state on the same sheet may be combined as appropriate.

In addition, in the price setting operation screen of FIG. 13, in the connection information code area AR34, instead of the connection information code CD being erased, for example, "connected" indicates that the weighing and price setting device 10 is currently connected to the mobile terminal device 40. Connection correspondence information indicating that the device is connected to is displayed.

By displaying the connection compatible information in the connection information code area AR34, the customer can select the product selection area AR32 shown in the figure as a result of communication between the customer's mobile terminal device 40 and the weighing and pricing device 10. You can confirm that the display has changed to . Further, for example, when a customer moves a little away from the weighing and pricing device 10 for some reason, a situation may arise in which another customer attempts to use the weighing and pricing device 10. Even in such a situation, other customers can see that the weighing and pricing device 10 is being used by a customer other than themselves by viewing the display of connection support information.

Further, in the message area ARm of the same figure, a message is displayed to guide the customer to operate the product button BT1 in order to specify the item of the product to be priced.

Note that the connection correspondence information may be displayed in a manner other than the above-mentioned “connected” display. Examples of the connection correspondence information include a terminal number, a membership number, a member registration name, a handle name, a character, a serial number, a background color setting of a pricing operation screen, and an elapsed time of connection with the mobile terminal device 40.
The terminal number is a number assigned to the mobile terminal device 40 that is the connection destination. Since a terminal number and a customer uniquely correspond to each other in a store, the terminal number can be treated as information indicating the customer.
The member number is a number given to the user (member) of the shopping application installed in the mobile terminal device 40 to which the member is connected. The member registration name, handle name, etc. are names registered by the user (member) of the shopping application installed in the mobile terminal device 40 to which the connection destination is connected.
The character is displayed as an icon-like image corresponding to a customer, for example. The display of the character indicates that the weighing and pricing device 10 and the mobile terminal device 40 are connected and that a customer is being served who is pricing a provisionally registered product. The character corresponding to the customer may be selected, for example, when the customer registers as a member using a shopping application. Alternatively, the characters corresponding to the customers may be assigned to the customers in order from among a predetermined number of types prepared by, for example, being stored in the weighing and pricing device 10 in advance.
The reference number is, for example, a number given to a customer waiting for a price to be placed using the weighing and pricing device 10.
The background color setting of the pricing operation screen is changed to a different background color when the mobile terminal device 40 is connected, for example, than when the mobile terminal device 40 is not connected. Further, regarding the background color after the change, a predetermined color may be associated with each customer (it may be allowed that the same color is associated with certain customers). The background color corresponding to a customer may be selected and set, for example, when the customer registers as a member using a shopping application. Alternatively, the background color corresponding to each customer may be sequentially assigned to each customer from among a predetermined number of colors prepared by, for example, being stored in the weighing and pricing device 10 in advance.
The connection elapsed time is the elapsed time during which the mobile terminal device 40 is connected. Such elapsed time indicates the elapsed time during which the customer using the mobile terminal device 40 exclusively uses the weighing and pricing device 10 for pricing.
By displaying such connection correspondence information, the customer can confirm that his or her mobile terminal device 40 and weighing and pricing device 10 are connected. Further, other customers can know that the weighing and pricing device 10 is being used by a customer other than themselves.

Further, in a state where the weighing and pricing device 10 and the mobile terminal device 40 are connected, predetermined connection correspondence information may be displayed on the mobile terminal device 40 as well. The connection correspondence information displayed on the mobile terminal device 40 includes, for example, a display simply indicating that the connection is in progress, as well as a number assigned to the connected weighing and pricing device 10, and a display of the connecting destination weighing and pricing device 10. Ten types may be displayed.
With such a display, the customer can confirm whether or not the customer is connected to the weighing and pricing device 10 by looking at the display on his or her mobile terminal device 40. Furthermore, when a plurality of weighing and pricing devices 10 are installed, it is possible to confirm which weighing and pricing device 10 is connected by the displayed number and the like.

A pricing operation screen similar to that displayed on the weighing and pricing device 10 may be displayed on the mobile terminal device 40 as well. Thereby, the customer can perform the operation of pricing and registering the temporarily registered product on both the mobile terminal device 40 and the weighing and pricing device 10.

Further, in the mobile terminal device 40, the pricing operation screen may not be displayed. In this case, for example, a product registration screen or the like may be displayed on the mobile terminal device 40. In this case, the customer performs all operations related to pricing on the weighing and pricing device 10. Therefore, in response to being connected to the weighing and pricing device 10 by reading the connection information code CD, the mobile terminal device 40 in this case displays, for example, “Currently communicating with the weighing and pricing device. A message such as "Please operate" may be displayed. Moreover, such a display may be performed until the mobile terminal device 40 receives product pricing information that reflects the pricing processing results.

In the following description, a case will be exemplified in which a customer registers by operating a pricing operation screen displayed on the weighing and pricing device 10.
Here, the customer first registers from the Apple AP out of the Apple AP and Lemon LM which are in the provisional registration state. Therefore, the customer operated the product button BT1 corresponding to the apple AP. As a result, the apple AP is designated as a pricing target.

In response to the apple AP being specified as a pricing target, the display on the customer display section 106 of the weighing and pricing device 10 changes from the pricing operation screen to the weighing guidance screen.
FIG. 14 shows an example of the measurement guide screen. In the measurement guide screen shown in the same figure, parts that are the same as those in the pricing operation screens shown in FIGS. 12 and 13 are given the same reference numerals.
In the weighing guide screen, a weighing guide area AR36 is arranged in place of the product selection area AR32 arranged in the pricing operation screen. In the weighing guide area AR36 in the figure, the words "apple" and a picture of an apple are displayed. A message area ARm is also arranged in the measurement guide area AR36. In the message area ARm of the weighing guidance area AR36, a message such as "PLACE ITEM" is displayed to guide the customer to place the apple AP on the scale stand 109b.
With such a display, the customer can confirm that the product button BT1 that he or she operated corresponds to the apple AP and is correct. Further, the customer can understand that the apple AP of the sold-by-weight products to be purchased should be placed on the scale stand 109b.

When the weighing guide screen shown in the figure is displayed, the apple AP to be priced has not yet been placed on the scale table 109b.
In this manner, before the apple AP is placed on the scale table 109b, the display in the weighing result area AR31 of the pricing operation screen is as follows. In other words, the weight area AR31-1 indicates that the weight is zero since no weighing has been performed yet. The weight unit price area AR31-2 indicates the weight unit price of the apple AP specified as a pricing target. The weight unit price displayed in this manner may be obtained from the product information of the apple AP in the product master, for example. The total price area AR31-3 indicates that the price is zero. In this way, the pre-weighing content displayed in the weighing result area AR31 of the pricing operation screen is also included in the weighing result shown in the weighing result area AR31.

Further, in the measurement guide area AR36, a return button BT14 and a cancel button BT15 are arranged. The return button BT14 is a button used to return to the previous screen. The cancel button BT15 is a button for performing an operation for instructing to cancel the registration by weighing and pricing of the sold-by-weight product in the provisionally registered state.
If the customer operates the cancel button BT12 at this time, the temporary registration state of the apple AP is canceled. In this case, the customer may return the apple AP brought from the display area to the display area or keep it as a reserved product and hand it to the store clerk at the time of checkout.

Furthermore, while the measurement guide screen is being displayed, the connection between the measurement and pricing device 10 and the mobile terminal device 40 continues. Accordingly, the connection information code area AR34 where the connection notification display has been performed is placed on the measurement guide screen shown in the same figure, continuing from the pricing operation screen shown in FIG.

With the weighing guidance screen shown in the figure being displayed, the customer places the apple AP to be priced on the scale stand 109b.
In response to the apple AP being placed on the scale table 109b, the weighing and pricing device 10 executes a pricing process. That is, the weighing and pricing device 10 determines the weight of the apple AP in response to determining that the weight of the apple AP measured by the weighing unit 109 is stable, and calculates the price based on the determined weight and the weight unit price. do.

In response to the pricing process being executed in this way, the display on the customer display section 106 changes from the weighing guide screen in FIG. 14 to the weighing result screen.
FIG. 15 shows an example of a measurement result screen. In this figure, the same parts as those in FIG. 14 are given the same reference numerals, and the explanation will be omitted as appropriate.
In the weighing result screen in the same figure, the weight of the apple AP weighed in the weight area AR31-1 is shown in the weighing result area AR31, and the weight of the apple AP weighed in the total price area AR31-3 is displayed according to the calculated price of the apple AP. The state has changed to show the total amount.
Further, in the measurement guide area AR36, a label issue button BT16 is arranged.
In addition, in the message area ARm, a message such as "PRINT LABEL" is displayed asking the customer to operate the label issue button BT16 in order to issue a label (single item label) that reflects the pricing processing result of the apple AP. A prompting message will be displayed.

In this case, the customer operates the label issue button BT16. In this case, the weighing and pricing device 10 finalizes the pricing by the pricing process in response to the operation of the label issue button BT16, and prints a label that reflects the pricing result determined for the apple AP. (single item label) is issued. Such an operation on the label issue button BT16 on the weighing result screen is also an operation by the customer to confirm the pricing results such as weight and price displayed in the weighing result area AR31.

Further, in response to the operation on the label issue button BT16, the weighing and pricing device 10 not only issues a label but also transmits product pricing information regarding the apple AP to the connected mobile terminal device 40. I do. In other words, the operation on the label issue button BT16 in this case serves as a trigger for instructing two processes: issuing a label and transmitting product pricing information.

Note that the weighing result screen may be configured such that the label issue button BT16 is not arranged. In this case, the weighing and pricing device 10 may issue a label and transmit product pricing information, for example, in response to the determination of the weight measured by the weighing unit 109.

Further, although not shown, after the label is issued, the display may transition from the weighing result screen to a label attachment guidance screen. On the label attachment guidance screen, messages, pictures, etc. are displayed to guide the user to attach the label issued by the weighing and pricing device 10 to the bag containing the apple AP that has been priced this time. It will be done.
Following the instructions, the customer lifts the apple AP from the scale stand 109b and attaches the label taken out from the label outlet 110a to the bag containing the apple AP.
The label attachment guide screen is erased, for example, when a sensor provided at the label outlet 110a detects that the label has been removed. Instead of erasing the label affixing guidance screen, the customer display section 106 changes to display a pricing operation screen for specifying the next item to be priced by weight. However, if, for example, some heavy object is still on the scale stand 109b at the timing when the label is taken out from the label discharge port 110a, a screen will be displayed to guide the customer to remove the heavy object from the scale stand 109b. Ru.

As mentioned above, at the timing when a pricing result is obtained for a product sold by weight in the provisionally registered state and a label is issued, the weighing and pricing device 10 transfers the product registration information of Apple AP, which reflects the pricing result, to the mobile terminal. to the device 40.
Note that the weighing and pricing device 10 may transmit the product registration information to the transaction management server 50 via a communication line.

FIG. 16 shows a pricing operation screen that is displayed in place of the label pasting guidance screen in response to the issue of the apple AP label.
In the pricing operation screen shown in FIG. 13, the apple AP product button BT1 that was displayed on the pricing operation screen shown in FIG. 13 is grayed out and cannot be operated. Note that the product button BT-1 of the apple AP may be erased instead of being grayed out. That is, the product selection area AR32 on the pricing operation screen is configured so that only operations for bulk products that are temporarily registered are possible.
Further, when the pricing operation screen shown in the figure is displayed, a pricing operation screen that allows the same operations as shown in the figure may also be displayed on the mobile terminal device 40.

With the pricing operation screen shown in the figure being displayed, the customer operates the product button BT1 for the lemon LM in order to make the lemon LM, which is still in the provisional registration state, a target for pricing.

After operating the product button BT11-2 corresponding to the lemon LM, the customer causes the weighing and pricing device 10 to price the lemon LM and issue a label in the same manner as the apple AP described above. . In response to the issuance of the label for Lemon LM, the pricing process (registration) for all sold-by-weight products that were in the provisional registration state has been completed.

In response to the completion of registration for all sold-by-weight products that were in the provisional registration state, the display on the customer display section 106 of the weighing and pricing device 10 returns to the initial state of the pricing operation screen (FIG. 12). be done.

In addition, in response to completion of registration for all sold-by-weight products that were in the provisional registration state, the product registration screen displayed on the touch panel display unit 406 of the mobile terminal device 40 changes to the state shown in FIG. 17, for example. Become.
The product registration status area AR12 on the product registration screen in the figure has changed as follows when compared with FIG. 11. That is, the registration list items AR122-1 and AR122-2 corresponding to the lemon LM and the apple AP have changed from a state indicating provisional registration to a state indicating registered. Specifically, the background color of each of the registration list items AR122-1 and AR122-2 changes from a color indicating a provisional registration state to a color indicating a registered state. Furthermore, the prices determined by the pricing process are shown in each of the registration list items AR122-1 and AR122-2. Furthermore, the comment display CM for each of the registration list items AR122-1 and AR122-2 has changed from "Metricing Required" to "Measuring". The comment display CM "weighing" indicates that the corresponding product is a product sold by weight and is registered through weighing and pricing processes. Therefore, instead of displaying "measured", the comment display CM may display "measured" or "registered", for example.
Furthermore, in the product registration status area AR12, for products sold by weight that have been weighed, information regarding the results of pricing processing such as the weighed weight, price, and unit price may be displayed.
Alternatively, the "weighing required" comment display CM itself may be deleted in response to the corresponding product being registered. Even in such a case, it is preferable to change aspects such as the background color of the registration list item AR122 in the product registration status area AR12 so that products sold by weight and products that are not sold by weight can be visually distinguished.

In addition, on the product registration screen displayed on the mobile terminal device 40, each time the registration of multiple sold-by-weight products in the temporary registration state is completed one by one, the registration list item AR122 of the sold-by-weight product whose registration has been completed is changed. The state may change to indicate that it has been registered.

With reference to the flowchart in Figure 18, an example of the processing procedure executed by the weighing pricing device 10, the mobile terminal device 40, and the transaction management server 50 of this embodiment in relation to the registration of products sold by weight in one transaction will be described.

First, an example of a processing procedure of the mobile terminal device 40 corresponding to a case where a customer uses the mobile terminal device 40 to input the item of a product sold by weight to be purchased will be described.
Step S2201: The mobile terminal device 40 waits for the product information code 3001 (FIG. 11) to be read while displaying the product registration screen on the touch panel display unit 406.

Step S2202: In response to the product information code 3001 being read, the mobile terminal device 40 acquires product information from the read product information code. By acquiring the product information, the mobile terminal device 40 has input the item of the product that the customer is purchasing.

Step S2203: The mobile terminal device 40 adds the registration list item AR122 indicating the product of the product information acquired in step S2202 to the product registration status area AR12 of the product registration screen. In this way, a product whose product information is acquired in response to reading the product information code 3001 is treated as a temporarily registered product. The registration list item AR122 of the provisionally registered product is set with a background color indicating that it is provisionally registered, like the registration list items AR122-2 and AR122-3 in FIG. is displayed to indicate that pricing has not yet been performed.
After the process in step S2203, the process returns to step S2201.

Next, an example of a processing procedure executed by the weighing and pricing device 10 in response to pricing of temporarily registered products will be described.
Step S2101: The weighing and pricing device 10 sets a standby mode in a state (standby state) in which no operation related to pricing is performed by the customer. In the standby mode, the weighing and pricing device 10 causes the customer display section 106 to display an initial pricing operation screen, as illustrated in FIG. As shown in FIG. 12, the connection information code CD is displayed on the pricing operation screen.

Step S2102: In the standby state, the weighing and pricing apparatus 10 determines whether connection processing with the mobile terminal device 40 that has read the connection information code CD has been started.

Step S2103: If it is determined in step S2102 that the connection process is not started, the weighing and pricing device 10 determines whether or not the customer has performed an operation to select a product to be priced. The selection operation of the product to be priced is performed using the product button placed on the sheet corresponding to any of the tabs TB-2, TB-3, and tab TB-4 placed in the product selection area AR32 of the pricing operation screen. This is an operation for BT1.

Step S2104: If it is determined that the selection operation of the product to be priced is not performed, the weighing and pricing device 10 determines whether the weighing section 109 has started weighing due to the customer placing the product on the scale stand 109b. Determine whether
If it is determined that the measuring unit 109 does not start measuring, the process returns to step S2101.

Step S2105: If it is determined in step S2103 that the selection operation of the product to be priced has been performed, or if it is determined in step S2104 that weighing has started, the weighing and pricing device 10 A pricing process corresponding to a transaction that does not use the mobile terminal device 40 is executed for the product.

If it is determined in step S2103 that a product selection operation has been performed as the pricing process in step S2015 corresponding to a transaction that does not use the mobile terminal device 40, the weighing and pricing device 10 A measurement guide screen corresponding to the selected product is displayed in a manner similar to that shown in FIG. Further, in the connection information code area AR34 on the measurement guide screen in this case, the connection information code CD may be deleted, and a message such as "Connecting" is not displayed. Note that the connection information code CD may also be displayed on the measurement guidance screen corresponding to a transaction that does not use the mobile terminal device 40. In this case, the connection information code CD may be displayed until the pricing process results are finalized and the label is issued, or at a predetermined timing before the pricing process results are finalized and the label is issued. May be deleted.

The weighing and pricing device 10 that displays the above-mentioned weighing guidance screen displays the product to be priced based on the weighing result of the weighing section 109 in response to the customer placing the product to be priced on the weighing platform 109b. Calculate the price.
When the price is calculated, the weighing and pricing device 10 displays a weighing result screen. Such a weighing result screen has a form similar to that shown in FIG. 15, has content that guides the customer to the operation of issuing a label, and has a label issue button BT16 arranged thereon.

The weighing and pricing device 10 issues a label (single item label) that reflects the pricing processing result of the current pricing target product in response to the label issuing button BT16 being operated. Thereafter, the weighing and pricing device 10 returns the process to step S2101, displays the initial pricing operation screen, and enters the standby mode.
On the label issued under the pricing process in step S2105, code information such as a barcode having content reflecting the pricing process results such as product item and price is printed. The products priced through the pricing process in step S2105 are registered at a POS terminal (not shown) operated by a store clerk who interacts with customers. The store clerk registers the product by having the POS terminal read the code information on the label.

Note that the code information on the label may be readable not only by the POS terminal but also by the mobile terminal device 40. Even for customers who use the mobile terminal device 40, there is a possibility that, for example, a clerk may make a mistake and issue a label with code information printed on it. In this case, the weighing and pricing device 10 will not transmit product pricing information to the mobile terminal device 40. Even if such a situation occurs, if the code information on the label is read by the mobile terminal device 40, the mobile terminal device 40 can acquire the product pricing information.
Note that in this embodiment, even if the code information is printed on the label issued in response to the customer using the mobile terminal device 40 in step S2111, there is no particular problem in operations such as payment. In addition, in this embodiment, in the case of a customer using the mobile terminal device 40, the mobile terminal device 40 can be used to read the code information printed on the label without having the mobile terminal device 40 read the code information printed on the label. It is possible to obtain product pricing information through communication with.

Further, as the pricing process in step S2015, if it is determined in step S2104 that weighing has started, the weighing and pricing device 10 selects the product button BT1 for the pricing operation screen that is displayed at that time. Wait for operation. The customer finds the product button BT1 corresponding to the product placed on the scale stand 109b from the product selection area AR32 on the pricing operation screen, and operates the found product button BT1. The weighing and pricing device 10 sets the product corresponding to the operated product button BT1 as a price target.
When the product corresponding to the operated product button BT1 is set as a price target, the weighing and pricing device 10 calculates the price of the product to be priced based on the weighing result of the weighing unit 109.
Once the price has been calculated, the weighing and pricing device 10 displays a weighing result screen with content that guides the customer through label issuing operations and on which a label issuing button BT16 is arranged. The weighing and pricing device 10 issues a label (single item label) that reflects the pricing processing result of the current pricing target product in response to the label issuing button BT16 being operated. Thereafter, the weighing and pricing device 10 returns the process to step S2101, displays the initial state pricing operation screen, and enters the standby mode.

Step S2106: If it is determined in step S2102 that the connection process has been started, the weighing and pricing apparatus 10 executes the started connection process and establishes a connection with the mobile terminal device 40.

Step S2107: Once the connection is established, the mobile terminal device 40 transmits temporarily registered product information. The weighing and pricing device 10 acquires the transmitted temporarily registered product information. The temporarily registered product information is a product sold by weight, such as an apple AP or a lemon LM, for which the item is input in response to the mobile terminal device 40 reading the product information code 3001.

Step S2108: The weighing and pricing device 10 that has acquired the temporarily registered product information displays a pricing operation screen corresponding to the temporarily registered product. The pricing operation screen for temporarily registered products is in the form illustrated in FIG. 13 .

Step S2109: After displaying the pricing operation screen, the weighing and pricing device 10 executes pricing processing in accordance with the customer's pricing operation. That is, the customer operates the product button BT1 on the pricing operation screen shown in FIG. 13 to specify the temporarily registered product to be subject to pricing processing. The weighing and pricing device 10 displays a weighing guide screen in the form illustrated in FIG. 14 in response to the operation of the product button BT1. The customer places the provisionally registered product designated as the subject of pricing processing on the scale stand 109b, and causes the weighing section 109 to weigh it. The weighing and pricing device 10 calculates the price using the weight measured by the weighing unit 109 and the weight unit price indicated in the temporarily registered product information acquired in step S2107.

Step S2110: In response to the price being determined by the pricing process in step S2109, the weighing and pricing device 10 causes the customer display section 106 to display a weighing result screen as illustrated in FIG. 15. The weighing and pricing device 10 displays the weighed weight and calculated price together with the weight unit price in the weighing result area AR31 of the weighing result screen.

Step S2111: A label issue button BT16 is arranged on the weighing result screen. The customer operates the label issue button BT16. In response to the operation of the label issue button BT16, the weighing and pricing device 10 issues a label corresponding to the product priced in the pricing process of the current step S2018. When the pricing process in step S2109 is executed, product pricing information is transmitted to the transaction management server 50 in step S2112, which will be described later. That is, the result of the pricing process is passed to the transaction management server 50. Therefore, for the label issued in step S2111, the code information reflecting the result of the pricing process does not need to be printed.

Note that, as the processing in step S2111, the weighing and pricing apparatus 10 may issue a label in response to, for example, completion of the pricing process in step S2109 and the price being determined. In this case, the display of the label issue button BT16 on the weighing result screen may be omitted.

Step S2112: Further, the weighing and pricing device 10 transmits product pricing information to the mobile terminal device 40 in response to completion of the pricing process in step S2108 and the price being determined. The product pricing information reflects the result of the pricing process for the product targeted for the pricing process in step S2109 this time.

Step S2113: After transmitting the product pricing information in step S2112, the weighing and pricing device 10 determines whether pricing processing for all temporarily registered products has been completed.
If there are still products for which the pricing process has not been completed, the process returns to step S2108. In this case, in step S2108, the weighing and pricing device 10 displays a pricing operation screen in which the product button BT11 of the temporarily registered product for which pricing has been completed is disabled, as illustrated in FIG. 16. .

Step S2114: If it is determined in step S2113 that the pricing process for all provisionally registered products has been completed, the weighing and pricing device 10 disconnects from the mobile terminal device 40 established in step S2106.
After disconnecting from the mobile terminal device 40, the process returns to step S2101 to enter standby mode, and an initial pricing operation screen is displayed.

Next, an example of a processing procedure executed by the mobile terminal device 40 in connection with pricing of temporarily registered products will be described.
Step S2211: The mobile terminal device 40 waits for the connection information code CD to be read while displaying the product registration screen.

Step S2212: When the customer performs an operation to read the connection information code CD using the mobile terminal device 40, the mobile terminal device 40 reads the connection information code CD. In response to the reading of the connection information code CD, the mobile terminal device 40 performs processing for communicably connecting with the weighing and pricing device 10 according to the connection procedure indicated by the read connection information code CD. This is executed between the attachment device 10 and the attaching device 10.

Step S2213: When the connection with the weighing and pricing device 10 is established through the connection process in step S2212, the mobile terminal device 40 transmits the temporarily registered product information to the weighing and pricing device 10. The temporarily registered product information is information about sold-by-weight products for which the items have been input through the processing in steps S2201 to S2203.

Step S2214: The mobile terminal device 40 waits for the product pricing information transmitted from the weighing and pricing device 10 in step S2211 to be received. When the product pricing information is received, the mobile terminal device 40 transmits product registration information that reflects the pricing processing result indicated by the received product pricing information to the transaction management server 50. Further, in response to receiving the product pricing information, the mobile terminal device 40 determines that pricing for the temporarily registered product indicated by the product pricing information has been completed.

Step S2215: After the process in step S2214, the mobile terminal device 40 determines whether the pricing process for all temporarily registered products has been completed.
If there are still products for which the pricing process has not been completed, the process returns to step S2214. In this case, the mobile terminal device 40 waits for the product pricing information to be received in step S2214, and when the product pricing information is received, the pricing processing result indicated by the received product pricing information is The product registration information in which the information is reflected is transmitted to the transaction management server 50.

Step S2216: If it is determined in step S2215 that the pricing process for all temporarily registered products has been completed, the mobile terminal device 40 causes the touch panel display unit 406 to display a product registration screen.

Next, an example of a processing procedure executed by the transaction management server 50 will be described.
Step S2301: The transaction management server 50 waits for the product registration information transmitted from the mobile terminal device 40 in step S2215 to be received.
Step S2302: When the product registration information is received, the transaction management server 50 registers (adds) the received product registration information to the cart information corresponding to the current transaction. At this time, the transaction management server 50 searches for cart information associated with the same cart identification information as included in the received product registration information, and registers the product registration information in the searched cart information. By performing the process of step S2302, the temporary registration state for one product is canceled and the registration is completed. After the process in step S2302, the process returns to step S2301.

<Modified example>
Modifications of this embodiment will be described below.

[First modification]
For example, when purchasing a product sold by weight without using the mobile terminal device 40, the item of the product to be priced may be input in the following manner.
At a display place for sold-by-weight products, a tag device may be placed corresponding to each sold-by-weight product displayed. The tag device is communicably connected to the weighing and pricing device 10 by wire or wirelessly. The tag device also stores product information indicating the corresponding sold-by-weight product. Since the tag device includes a touch sensor, it can detect that the tag device has been touched by a touch operation.
In this case, the customer performs a touch operation on the tag device of the sold-by-weight product that he/she is purchasing. The tag device that detects the touch operation transmits the product information stored therein to the weighing and pricing device 10.

The weighing and pricing device 10 of this modified example has a product button BT1 arranged according to each product information received from the tag device in the product selection area AR32 of the pricing operation screen displayed corresponding to the standby mode. Display the sheet of tab TB-1 of “My Item”.
Here, when the weighing and pricing device 10 of this modification example is in standby mode and product information is not being received from the tag device, as shown in FIG. The sheet of the tab TB-2 of "POPULAR" may be displayed, in which the product button BT1 of the product registered in the classification is arranged. Then, in response to receiving the product information from the tag device, the weighing and pricing device 10 displays the "My Item" tab TB-1 in which the product button BT1 corresponding to the product information transmitted from the tag device is arranged. You may switch to the display of the sheet.

By performing such a display, for example, when a customer who does not use the mobile terminal device 40 goes to the weighing and pricing device 10, the product button BT1 of the product that he or she has entered as a purchase target by touching the tag device is displayed. is displayed. Thereby, the customer can immediately find and operate the product button BT1 of the product he or she wants to price.

Further, for example, when a customer who is able to use the mobile terminal device 40 forgets this and inputs the item of the product to be priced by touching the tag device, but goes to the weighing and pricing device 10. In some cases, the user may remember that the mobile terminal device 40 is available for use.
In such a case, the customer may connect the mobile terminal device 40 and the weighing and pricing device 10 by having the mobile terminal device 40 read the connection information code CD, for example, before operating the product button BT1.
In this case, the mobile terminal device 40 notifies the weighing and pricing device 10 that there is no temporarily registered product information. When receiving such a notification, the weighing and pricing device 10 changes the product button BT1 placed on the sheet corresponding to the "My Item" tab TB-1 on the pricing operation screen to the one corresponding to the temporarily registered product. It may be handled as a product button BT1 and subsequent pricing processing may be executed.
Alternatively, as described with reference to FIG. 11, the product information panel 3000 is not provided at the place where the products are displayed, and the tags are displayed on the customer regardless of whether or not they purchase the product by weight using the mobile terminal device 40. The user may be asked to perform a touch operation on the device. When purchasing a product sold by weight using the mobile terminal device 40, the customer has the mobile terminal device 40 read the connection information code CD before operating the product button BT1 as described above, and then connects the mobile terminal device 40 and the weighing device. The pricing device 10 is connected.

[Second modification]
Furthermore, input of the item of the product to be priced may be performed as follows.
In this modification, a movement sensor that detects movement is provided on a lid, lever, or other part that moves as a product is removed from a fixture in which sold-by-weight products are stored. Detection of movement by a motion sensor can be realized by, for example, an acceleration sensor, and product information indicating a corresponding sold-by-weight product is stored. The motion sensor transmits the product information stored therein to the weighing and pricing device 10 in response to detecting motion.
In this case, the customer takes out the product he/she wants to purchase from among the displayed products. In response to the removal of the product, the motion sensor corresponding to the product to be purchased detects movement. The motion sensor transmits product information stored therein to the weighing and pricing device 10 in response to detecting motion.

The weighing and pricing device 10 of this modification has product buttons BT1 arranged in accordance with each product information received from the motion sensor in the product selection area AR32 of the pricing operation screen displayed corresponding to the standby mode. Display the sheet of tab TB-1 of “My Item”.
Also in this modification, when the weighing and pricing device 10 is in a standby mode and product information is not being received from the motion sensor, the weighing and pricing device 10 selects a product registered in the product master under the category of sold-by-weight product in the product selection area AR32. The sheet of the "POPULAR" tab TB-2 on which the product button BT1 is arranged may be displayed. Then, in response to receiving the product information from the motion sensor, the weighing and pricing device 10 displays the "My Item" tab TB-1 in which the product button BT1 corresponding to the product information transmitted from the motion sensor is arranged. You may switch to displaying the sheet.

In this modification, a customer who does not use the mobile terminal device 40 directly operates the product button BT1 on the sheet of the tab TB-1 displayed on the weighing and pricing device 10 to specify the product to be priced. It's fine.
On the other hand, before operating the product button BT1, the customer using the mobile terminal device 40 causes the mobile terminal device 40 to read the connection information code CD displayed on the weighing and pricing screen, and then connects the mobile terminal device 40 with the weighing value. The attaching device 10 is connected. In this case, the weighing and pricing device 10 treats the product button BT1 placed on the sheet corresponding to the "My Item" tab TB-1 on the pricing operation screen as the product button BT1 corresponding to the temporarily registered product, Execute the subsequent pricing process.
In the operation of this modification, it is not necessary to provide the product information panel 3000 at the place where products are displayed as shown in FIG. 11.

[Third modification]
In the sixth embodiment, the weighing and pricing device 10 acquires the product information (temporarily registered product information) of the product to be priced (temporarily registered product) by receiving the temporarily registered product information transmitted from the mobile terminal device 40. Not limited.
For example, the weighing and pricing apparatus 10 is capable of displaying a product selection screen on the customer display section 106 in which preset keys corresponding to each product sold by weight are arranged. The product selection screen may have a form in which product buttons BT1 registered in advance as products sold by weight are arranged, as in the sheet of tab TB-2 in FIG. 12.
The customer can specify the product to be priced by the weighing and pricing device 10 by operating the preset keys arranged on the displayed product selection screen. The weighing and pricing device 10 may be configured to acquire product information of a product corresponding to the operated preset key as temporarily registered product information.
In this case, there is no need to transmit the product information of the product to be priced from the mobile terminal device 40 to the weighing and pricing device 10. Therefore, the weighing and pricing device 10 in this case does not display the connection information code CD on the standby screen, but displays the connection information code CD on the customer display section 106 at a predetermined timing according to the preset key operation, for example. It may be displayed. For example, the weighing and pricing device 10 may display the connection information code CD at the timing when the product selection screen on which the preset keys are arranged is displayed. Alternatively, the weighing and pricing device 10 performs the following operations at a predetermined timing from when a preset key is operated to select the first provisionally registered product until when a preset key is operated to select the last provisionally registered product. The connection information code CD may be displayed. Alternatively, the weighing and pricing device 10 may display the connection information code CD at the timing when the operations of the preset keys corresponding to all the bulk products to be purchased are completed. Alternatively, the weighing and pricing device 10 may display the connection information code CD at the timing when the pricing of at least one product is completed, after the operations of the preset keys corresponding to all of the products sold by weight to be purchased are completed. .

When the mobile terminal device 40 reads the connection information code CD and is communicably connected to the weighing and pricing device 10, temporarily registered product information can be transmitted from the weighing and pricing device 10 to the mobile terminal device 40. Thereby, the temporarily registered product information can be shared between the weighing and pricing device 10 and the mobile terminal device 40.
Further, in this case, the connection information code CD may be deleted at the timing when the connection between the weighing and pricing device 10 and the mobile terminal device 40 is established. Alternatively, the connection information code CD may be deleted, for example, at a timing corresponding to completion of pricing of all provisionally registered products.
