(Display of cancel (call clerk) button BT42 on screen GM3)
When the weighing device 20 displays the screen GM3 after the container containing the product is once placed on the platform 25a as part of the transaction (after the screen GM4 has been displayed once), the weighing device 20 presses the stop (self) button BT41 instead of the cancel (self) button BT41. It has been explained that the screen GM3 (not shown) on which the cancel (call clerk) button BT42 is displayed is displayed. On the other hand, as described above, when a container containing a product is placed on the platform 25a, the maximum product weight value does not become zero until the transaction is completed (from screen GM6 to screen GM1). Therefore, for example, when displaying the screen GM3 (when "GMNo3" is stored as the progress status information), the weighing device 20 refers to the maximum product weight value and places the stop (self) button BT41. It may be determined whether to display the screen GM3 or to display the screen GM3 on which the cancel (call clerk) button BT42 is arranged. That is, the weighing device 20 displays the screen GM3 on which the cancel (self) button BT41 is arranged if the product maximum weight value is "0 (g)", and if the product maximum weight value is "0 (g)". For example, a screen GM3 may be displayed on which a cancel (call clerk) button BT42 is arranged. The same applies to the display of the cancel (call clerk) button BT42 on the screen GM2.

In addition, instead of referring to the product maximum weighing value, the weighing device 20 uses a flag indicating that screen GM4 is displayed (for example, the initial value is "0" and becomes "1" when screen GM4 is displayed, indicating that the transaction is complete). It may be determined whether to display the screen GM3 on which the cancel (self) button BT41 is disposed or the screen GM3 on which the cancel (call clerk) button BT42 is disposed, using a flag (which is initialized at the time). The same applies to the display of the cancel (call clerk) button BT42 on the screen GM2.

(If the number of products in the container increases)
For example, if the customer adds a product to the container after transitioning from screen GM4 (or screen GM5) to screen GM3 and places the container after adding the product on the platform 25a, the weighing device 20 At the time of transition from screen GM3 to screen GM4, the following information is updated as follows. It is assumed that the weight of the container after adding the product is 726 g (that is, the weight of the product placed in the container increases by 100 g to 704 g).
Current weight value in Figure 4 (A): Updated from 0 (g) to 726 (g) Product weight value in Figure 4 (C): Updated from 0 (g) to 704 (g) Product maximum in Figure 4 (D) Weighing value: Updated from 604 (g) to 704 (g) Progress status information in Figure 4 (E): Updated from GM No. 3 to GM No. 4 In other words, when the number of products in the container increases, the maximum product weight value after the increase updated to the value.

(If the product in the container decreases)
For example, if the customer removes a part of the product from the container and places the container from which part of the product has been removed on the platform 25a after transitioning from screen GM4 (or screen GM5) to screen GM3, the weighing device 20 , at the time of transition from screen GM3 to screen GM4 due to the placement, it is recognized that the product weight value is less than the product maximum weight value. For example, if the weight of the container after removing a part of the product is 526g (that is, the weight of the product in the container is reduced by 100g to 504g), the weighing device 20 calculates the product weight value "504 (g)". )" is less than the maximum product weight value "604 (g)". In this case, the weighing device 20 may call the clerk and display a screen (not shown) indicating that the clerk is being called.

(If the product in the container runs out)
For example, if the customer removes all of the products in the container after transitioning from screen GM4 (or screen GM5) to screen GM3 and places the empty container from which all of the products have been removed on the platform 25a, the weighing device 20 At the time of transition from screen GM3 to screen GM2 due to the placement, it is recognized that a value other than zero is stored as the maximum product weight value. If the product is never placed in the container, the maximum product weight value is zero, but if the product is placed in the container even once, the maximum product weight value is not zero, so the weighing device 20 At the same time, a screen (not shown) may be displayed to indicate that the clerk is being called.

(If the current weight value is less than the tare weight value)
After weighing an empty container and taking the empty container from the mounting table 25a (while transitioning from screen GM2 to screen GM3 and displaying screen GM3), the customer will be asked if the empty container is different from the weighed container. When a container (lighter than a weighed container) is placed on the platform 25a, the weighing device 20 recognizes that the current weight value is less than the tare weight value. For example, if the initially weighed container weighs 22g and another weighs 10g, the weighing device 20 recognizes that the current weight value "10 (g)" is less than the tare weight value "22 (g)". do. In this case, the weighing device 20 may call the clerk and display a screen (not shown) indicating that the clerk is being called. Note that even if the weight of another container containing the product is less than the tare weight value (for example, when 10g of product is placed in another 10g container), the weighing device 20 will display the current weighing value " 20 (g)" is less than the tare weight value "22 (g)," in this case as well, the system calls the clerk and displays a screen (not shown) indicating that the clerk is being called. It's okay.

The embodiments have been described above, and according to the embodiments, metered sales are improved.

The embodiments have been described above, but the embodiments are merely examples, and the specific configuration is not limited to the embodiments described above, and includes designs within the scope of the invention. For example, the following (1) to (10) may be used. Furthermore, the following (1) to (10) may be combined as appropriate.

(1) In the above embodiment, it was explained that the basic screen transition is Screen GM1 → Screen GM2 → Screen GM3 → Screen GM4 → Screen GM5 → Screen GM6 (→ Screen GM1), but some screens are common. It can also be used as a screen.

(Transition a by screen GMa)
For example, a common screen (referred to as screen GMa) that combines the contents of screen GM3 and screen GM4 is prepared, and the transition (referred to as transition a) is as follows: screen GM1 → screen GM2 → screen GMa → screen GM5 → screen GM6 (→screen GM1) ). The screen GMa of transition a may be, for example, the following screen. The same content as the numerical display area HR1 of the screen GM3 is displayed in the numerical display area HR1 of the screen GMa. The message on screen GMa is a message that includes (or extracts) the contents of each message (message MS13, MS14) on screen GM3 and screen GM4. The image of screen GMa is an image that includes (or extracts) the contents of image GA33 of screen GM3. Screen GMa is provided with a product button display area HR2 similar to screen GM4. A cancel (self) button BT41 is arranged on the screen GMa (in the case where the screen GMa is displayed after the container containing the product for the transaction is once placed on the platform 25a, a cancel (self-call) button BT42 is arranged )do. In transition a, the tare weight, which is the weight of the empty container, is measured, and then, when the empty container is taken (when the weighed value is zero (or approximately zero)), the product can be selected. Display the screen (screen GMa).

(Transition b by screen GMb)
In addition, a common screen (referred to as screen GMb) that combines the contents of screen GM2 to screen GM4 is prepared, and the screen is transitioned (referred to as transition b) from screen GM1 → screen GMb → screen GM5 → screen GM6 (→screen GM1). Good too. The screen GMb of transition b may be, for example, the following screen. The same content as the numerical display area HR1 of the screen GM2 is displayed in the numerical display area HR1 of the screen GMb. The message on screen GMb includes (or extracts) the contents of each message (message MS12 to MS14) on screen GM2 to screen GM4. The image of screen GMb is an image that includes (or extracts) the contents of each image (images GA32, GA33) of screen GM2 and screen GM3. Screen GMb is provided with a product button display area HR2 similar to screen GM4. A cancel (self) button BT41 is arranged on the screen GMb (in the case where the screen GMb is displayed after the container containing the product for the transaction is once placed on the platform 25a, a cancel (self-call) button BT42 is arranged )do. In transition b, when the tare weight, which is the weight of the empty container, is measured, a screen (screen GMb) on which a product can be selected is displayed immediately.

(2) In the above embodiment, it has been explained that if a weight exceeding the tare weighing value is detected on screen GM3, the screen will transition to screen GM4. (In other words, if the excess weight is less than a predetermined weight, the screen may not transition to GM4). In other words, the minimum purchase amount of the product may be set as the predetermined weight. Note that if the weight is less than a predetermined weight, a message may be displayed to the effect that the minimum purchase amount is not met or that it is necessary to put in more than the minimum purchase amount.

(3) In the above embodiment, when a product is added after selecting a product, the product needs to be specified again. However, when a product is added after selecting the product, there is no need to specify the product again (omitted) ) may be done. That is, instead of the screen GM4 → screen GM5 → screen GM3 → screen GM4 → screen GM5, the transition may be as follows: screen GM4 → screen GM5 → screen GM3 → screen GM5. If it is within a certain period of time after the transition from screen GM5 to screen GM3, the transition may be from screen GM4 to screen GM5 to screen GM3 to screen GM5.

(4) In the above embodiment, after tare weighing (display on screen GM2), the initial screen is returned to the initial screen (screen GM1) when processing is completed or cancelled. You can also go back. As an example, when the screen GM3 continues to be displayed for a predetermined time or more, the screen GM may be transitioned to the screen GM1 (a countdown of the time until the transition to the screen GM1 may be displayed on the screen GM3).

(5) In the above embodiment, the procedure is to place an empty container on the platform 25a (weigh the tare weight), take the empty container from the platform 25a, put the product in it, and place the container with the product in it again. Although the example of placing the product on the stand 25a has been explained, instead of or in addition to the above procedure, an empty container may be placed on the stand 25a (the tare weight is measured), and the product may be placed while the empty container is placed on the stand 25a. (For example, the scoop of the display container 200 may be used to put the product in.) In this case, instead of or in addition to the message (message MS11) that advises to take out the empty container and fill it with products, or the image (image GA31) that advises to take out the empty container, A message indicating that the product should be loaded with the container still on it or an image that indicates that the product should be loaded with the empty container still on the container may be displayed. In addition, when a product is put in with an empty container still on it, the screen changes from screen GM2 to screen GM4.

(6) In the above embodiment, an example has been described in which the weighing device 20 recognizes that another container different from the weighed container is placed on the mounting table 25a through weighing. The method of recognizing that it has been placed on the stand 25a is not limited to this. For example, the weighing device 20 may include an imaging unit that captures an image of what is placed on the platform 25a, and may recognize that another container has been placed on the platform 25a.

(7) In the above embodiment, an example was explained in which the weighing device 20 does not recognize the purchased product at all before the customer performs an operation on the screen (selecting a product on the screen GM4). The weighing device 20 may recognize the purchased product (more precisely, the product whose display container was operated) before the operation is performed. For example, a sensor 203 (for example, a sensor including a tilt sensor, a storage unit (a storage unit that stores the product code of the product stored in the display container 200), and a communication unit) is installed in the display container 200 (operation unit 202). However, when the customer operates the operation unit 202 of the display container 200, the sensor 203 transmits detection information including the product code stored in the storage unit to the weighing device 20, and the weighing device 20 receives the detection information from the sensor 203. , it may be recognized that the product with the product code included in the detection information is the product for which the display container 200 was operated. Weighing device 20 may display only the product button of the product for which display container 200 is operated on screen GM4 (product button display region HR2). Note that if the file indicating the correspondence between the display container 200 and the products stored in the display container 200 can be referenced (if the file is stored in the own device or an accessible external device), the sensor 203 may transmit detection information including information that allows the display container 200 to be identified. Further, if the file indicating the correspondence between the sensor 203 and the products stored in the display container 200 in which the sensor 203 is installed can be referenced (if the file is stored in the own device or an accessible external device), ), the sensor 203 may transmit detection information including information by which the sensor 203 can be identified. A similar sensor may be installed in each of the display containers 100, 300, 310, and the weighing device 20 may display only the product button of the product for which the display container 100, 300, 310 was operated on the screen GM4.

(8) Related to (7) above, a code image (barcode or two-dimensional code) that encodes the product code of each product is presented in the display area, and the customer receives the code of the product to purchase. By capturing an image with a mobile terminal (e.g., the customer's own smartphone or a smartphone lent by the store), and then communicating with the weighing device 20 (e.g., Bluetooth communication), the weighing device 20 may recognize the product that the customer is purchasing, and display only the product button for the product on screen GM4. Note that the mobile terminal displays a two-dimensional code that encodes the information necessary for communication (pairing) (terminal identification information, passkey, etc.), and the weighing device 20 has a scanner unit that optically reads the two-dimensional code, etc. The scanner unit may start communication between the mobile terminal and the weighing device 20 by reading a two-dimensional code displayed by the mobile terminal.

(9) In the above embodiment, an example was explained in which the weighing device 20 weighs an empty container and obtains the weight (tare weight) of the empty container, but the weighing device 20 measures the tare weight. The acquisition method is not limited to this.

For example, the tare weight may be obtained based on the customer's operation on the screen. For example, when using containers of known weight prepared by a store (containers provided free of charge or for a fee; hereinafter referred to as store containers), and where there are multiple store containers with different weights (for example, a 30g store container). A, 50g store container B, 100g store container C), store container buttons corresponding to the respective store containers (for example, store container button for store container A, store container button for store container B, store container button for store container C) ) may be displayed for the customer to select. The weighing device 20 stores the tare weight of each store container in association with each store container button, and converts the tare weight corresponding to the store container button operated by the customer into a tare weight value (FIG. 4(B)). ) as a memory (registration).
(Transition c by screen GMc)
For example, a screen (screen GMc) on which each store container button is arranged may be prepared, and the transition may be made as follows (referred to as transition c): screen GMc → screen GM3 → screen GM4 → screen GM5 → screen GM6 (→screen GMc) . Instead of transition c, each store container button is placed on screen GM1 (for example, when a store container and a container that is not a store container (that is, a container that requires weighing) are used together), and for example, screen GM1 → (screen GM2) → Screen GM3 → Screen GM4 → Screen GM5 → Screen GM6 (→ Screen GM1) may be changed. The same applies to the case where the weight of the store container is one type (the case where there is only one type of store container, or the case where all the weights of a plurality of store containers are the same). However, if the weight of the store container is one type, the customer does not need to select the store container, so the store container button may have another name (for example, a transaction start button). In other words, a single transaction start button is arranged on screen GMc and screen GM1 instead of multiple store container buttons, and when the transaction start button is operated, the tare weight of the store container is calculated by the tare weight value (Fig. 4(B)), and the screen may be changed in the same way.

Further, for example, an IC tag that stores the weight of the container is affixed to the container, and the weighing device 20 is equipped with a wireless tag reading section, and the wireless tag reading section is affixed to the container placed on the platform 25a. The weight (tare weight) of the container may be obtained by reading information stored in the IC tag. In addition, a barcode (or two-dimensional code) encoding the weight of the container is attached to the container, and the weighing device 20 is equipped with a scanner section, and the scanner section is attached to the container placed on the platform 25a. The weight (tare weight) of the container may be obtained by reading the barcode (or two-dimensional code) contained in the container. The weighing device 20 stores (registers) the tare weight acquired as described above as a tare weight value (FIG. 4(B)).
(Transition d by screen GMd)
For example, a screen (screen GMd) for guiding the reading of IC tags, etc. may be prepared, and the transition may be made as follows (referred to as transition d): screen GMd → screen GM3 → screen GM4 → screen GM5 → screen GM6 (→screen GMd). . Instead of transition d, guide the reading of IC tags, etc. on screen GM1 (for example, when containers with IC tags, etc. affixed and containers without IC tags, etc. (i.e., containers that require weighing) are used together. ), for example, the transition may be made as follows: screen GM1 → (screen GM2) → screen GM3 → screen GM4 → screen GM5 → screen GM6 (→screen GM1).

(10) In the above embodiment, an example was explained in which the weighing device 20 stores files (such as the product file shown in FIG. 3) and data (such as the various values shown in FIG. 4). For example, this information may be stored on a cloud server).

A summary of the embodiments will be described below.

[Problem to be solved by the invention]
However, there was room for improvement in measured sales. The present invention has been made in view of these circumstances, and its purpose is to provide a technique for improving metered sales.
[Means to solve the problem]
(1) In order to solve the above-mentioned problems, one aspect of the present invention provides a product sales data processing device (for example, a weighing device 2 ), comprising a measuring means (e.g., the measuring part 25) for measuring the weight, and a display means (e.g., the display part 26) for displaying an operable screen, the display means indicating the weight of the container. After the tare weight is registered (for example, after weighing the container by the measuring means, after selecting the container (store container), after reading the IC tag, etc.), a screen where the product can be selected (for example, screen GM4, screen GMa , screen GMb) (for example, screen GM4 is displayed after screen GM1, such as screen GM1 → screen GM2 → screen GM3 → screen GM4, and screen is displayed after screen GM1, such as screen GM1 → screen GM2 → screen GMa). This product sales data processing device is characterized by displaying GMa, and displaying screen GMb immediately after screen GM1 in the order of screen GM1→screen GMb.
According to (1) above, metered sales are improved. For example, it is possible to have the user select a product after properly recognizing the tare weight.

(2) The display means indicates that after the tare weight is registered, the measured value by the measuring means changes (for example, it decreases when the container is taken down and the product is put in, and it increases when the product is put in with the container still on it). ), then displays screens (for example, screen GM4, screen GMa) where products can be selected (for example, screen GM4 is displayed after screen GM2, screen GM1 is displayed after screen GM2, screen GM1 → screen GM2 → screen GM3 → screen GM4, etc.). The product sales data processing device according to item (1) is characterized in that the screen GMa is displayed immediately after the screen GM2 in the following manner: → screen GM2 → screen GMa.
According to (2) above, metered sales are improved. For example, after recognizing the tare weight, a product can be selected based on the action of putting the product in (the action of taking the container down) or the action of putting the product in (the action of putting the product into the container that is still loaded).

(3) The display means displays a screen (for example, screen GM4) on which a product can be selected based on the fact that the weighing means has measured a weight larger than the tare weight after registering the tare weight (for example, The product sales data processing device according to item (1) or (2) is characterized in that the screen GM4 is displayed immediately after the screen GM3 in the following order: screen GM1→screen GM2→screen GM3→screen GM4.
According to (3) above, metered sales are improved. For example, when a container containing a product is placed, the user can select the product.

(4) At least an issuance unit (e.g., printing unit 28) is provided for issuing a medium on which the sales price of the product is printed, and the display unit displays the registered tare weight (e.g., screen GM2) and the issuance When the issuance of the medium by the means is completed and the product is taken from the weighing means (for example, when the weighing value is zero (or approximately zero)), the tare weight is erased (for example, The product sales data processing device according to any one of (1) to (3) is characterized in that screen GM6→screen GM1).
According to (4) above, metered sales are improved. For example, if a product is left behind, the next process can be suitably restricted from starting. It also prevents items from being left behind.
