The CPU 21 is a central processing unit, and controls the operation of the weighing device 20 by reading and executing a program stored in the ROM 22.

The ROM 22 is a read-only memory, and stores, for example, various information used by the CPU 21 including a program.

The RAM 23 is a read / write memory, and stores various information such as information read from the ROM 22 and information acquired via the wireless tag reading unit 29.

The scanner unit 24 optically reads various types of information. For example, the scanner unit 24 reads various codes (bar code, two-dimensional code, etc.). In addition, in FIG. 1, FIG. 19 (C) and the like, the description of the scanner unit 24 is omitted.

The weighing unit 25 weighs what is placed on the platform 25a (commodity, container, etc.) by, for example, a weight detection method using a load cell.

The touch display 26 displays various information to the customer, is also provided with a touch panel, and has a function as an operation unit.

The audio output unit 27 outputs audio. For example, the voice output unit 214 outputs voice guidance and the like.

The printing unit 28 is a printer device that issues a medium. For example, the printing unit 28 generates (prints) a printed matter (hereinafter, also referred to as “label”) on which information about the product to be sold (such as a barcode that encodes the price information of the product) is printed, and removes the label. Discharge (issue) from outlet 28a.

The wireless tag reading unit 29 reads and writes information to the non-contact type IC tag. An example of a non-contact type is an RFID (radio frequency identifier) tag). In the following description, the non-contact type IC tag may be referred to as a wireless tag, a wireless IC tag, or the like. The wireless tag reading unit 29 executes reading and writing of information with the wireless tag (IC tag) by short-distance wireless communication using an electromagnetic field, radio waves, or the like. For example, details will be described with reference to FIGS. 7 and 8, but in the present embodiment, a label with a wireless tag (a label incorporating the wireless tag) is prepared, and the wireless tag reading unit 29 is concerned with the label. Read and write the weight information of the container to which the label is attached to and from the wireless tag attached to the label. The type of IC tag may be either a passive tag (passive tag), an active tag (active tag), or a semi-active tag (activated active tag) that is a combination of both, but a label attached to the container. A passive tag that does not require an internal battery is preferable because it is incorporated inside. The wireless tag reading unit 29 irradiates radio waves that serve as an energy source for the IC tag (passive tag).

The weighing device 20 may have a clock function (timekeeping function). The weighing device 20 having a clock function can manage, for example, the current time, the remaining time until a certain time, and the elapsed time from a certain state.

Further, even if the weighing device 20 includes a communication unit that transmits / receives information to / from another device by wireless (for example, wireless LAN (Local Area Network), Bluetooth (registered trademark), etc.) or by wire. good.

Further, in FIG. 3, the configuration in which the weighing device 20 includes the CPU 21, the ROM 22, and the RAM 22 has been described, but the weighing device 20 may be configured to include an MCU (Micro Controller Unit) instead of them. ..

4 and 5 are examples of information stored in the weighing device 20. The weighing device 20 stores a product file (also referred to as a product master) that holds basic product information (product name, price, etc.). For example, the weighing device 20 stores a product file (also referred to as a product master) as shown in FIG.

When the weighing device 20 includes a communication unit, a product file may be received and stored from an external device (a management device installed in a store (not shown), a cloud server existing outside the store, or the like). The same applies to other files such as the product button setting file (described later).

The product file shown in FIG. 4 includes product identification information, a product name, a weighing category, a unit price, and a unit weight as data items. Product identification information is identification information that identifies individual products. The product name is the name of the product.

The measurement category is a category related to measurement. As for the measurement category, "0" is a measurement category corresponding to "indefinite penetration". The indefinite penetration is a sales method in which the selling price is determined based on the unit price per unit weight (“100 g” in the present embodiment) set in advance and the weight to be sold (weighing value). For products of the weighing category "0 (indefinite penetration)", the weight to be sold is required when determining the selling price, so that the weighing device 20 needs to weigh the product.

When the weighing category is "0 (indefinite)", the unit price per unit weight is stored in the unit price column, and the unit weight is stored in the unit weight column. For example, in the case of a product with product identification information "SH001" (product name "AAA"), it is stored that the unit price per 100 g is 250 yen. Therefore, for a product with the product name "AAA", for example, if the weighed value is 50 g, the selling price is 125 yen, and if the weighed value is 200 g, the selling price is 500 yen.

As for the weighing category, "1" is a weighing category corresponding to "constant". The fixed number is a sales method in which the selling price is determined based on the unit price per unit quantity (“1 piece” in the present embodiment) set in advance and the selling quantity converted from the unit weight. For products in the weighing category "1 (constant)", the quantity of the product is calculated (estimated) from the unit weight of the product (the weight of one unit, which is already stored) and the weighing value. Since the selling price is determined from the calculated quantity of the product and the unit price per unit quantity, weighing by the weighing device 20 is necessary. For the weight error of an individual, an accuracy correction function provided in a counting scale or the like may be used.

When the weighing category is "1 (constant)", the unit price per unit weight (that is, quantity 1) is stored in the unit price column, and the unit weight corresponding to the quantity 1 is stored in the unit weight column. There is. For example, in the case of a product (product name "ABC") with product identification information "SH103", it is stored that the unit price per product (weight 80 g) is 90. Therefore, for a product with the product name "ABC", for example, if the weighing value is about 85 g, the selling price is 90 yen for one piece, and if the weighing value is about 150 g, the selling price is 180 yen for two pieces. Become.

As for the weighing category, "2" is a weighing category corresponding to "fixed amount". The fixed amount is a sales method in which the selling price is determined based on the unit price per unit quantity (“1 piece” in the present embodiment) set in advance and the selling quantity in which the number is input. For products of the weighing category "2 (fixed amount)", the sales quantity is determined by the number of units regardless of the weight, so that the weighing by the weighing device 20 is not necessary.

When the weighing category is "2 (fixed amount)", the unit price per quantity is stored in the unit price column (nothing is stored in the unit weight column). For example, in the case of a product with product identification information "SH150" (product name "AAAA"), it is stored that the unit price per product is 120. Therefore, for a product with the product name "AAAA", for example, if the number input value is 1, the selling price is 120 yen for one piece, and if the number input value is 2, the selling price is 240 for two pieces. It becomes a circle.

Further, the weighing device 20 stores a store container file (also referred to as a container master, not shown) that holds basic information (weight, etc.) of the store container.

The non-illustrated store container file includes store container identification information, store container weight information, and store container price information as data items. The store container identification information is container identification information related to the store container. The container identification information is identification information for identifying the container. The container identification information is, for example, identification information capable of identifying each of My Container, Container S (one of the store containers), Container M (one of the store containers), and Container L (one of the store containers). For example, the container identification information "10" is my container, the container identification information "21" is the container S, the container identification information "22" is the container M, the container identification information "23" is the container L, and the like. Since the store container identification information is the container identification information related to the store container as described above, the store container identification information "21" is the container S, the store container identification information "22" is the container M, and the store container identification information "23". Is the container L. The store container weight information is the weight information of each store container. The store container price information is the price information of each store container.

Further, the weighing device 20 stores in the RAM 22 a button setting file related to a button that is operably displayed on the touch display 26. For example, the weighing device 20 stores a product button setting file (FIG. 5) related to the product button and a container button setting file (not shown) related to the container button in the RAM 22.

The product button setting file shown in FIG. 5 includes product identification information, product button identification information, and button images as data items. Product identification information is identification information that identifies individual products. The product button identification information is identification information that identifies the product button. The button image is image data of the product button. That is, the product button setting file stores the relationship between the product and the product button.

The container button setting file (not shown) (not shown) includes container identification information, container button identification information, and button images as data items. The container identification information is identification information for identifying the container. The container button identification information is identification information for identifying the container button. The container button identification information includes, for example, my container button, store container button, container S button (one of the store container type buttons), container M button (one of the store container type buttons), and container L button (store container type button). It is identification information that can identify each of (one of). The button image is image data of the container button. That is, the container button setting file stores the relationship between the container and the container button.

The above-mentioned file is an example of a file stored by the weighing device 20, and the measuring device 20 may store a file other than the above-mentioned file.

Further, the weighing device 20 only needs to be able to refer to the above-mentioned file illustrated, and the measuring device 20 itself does not necessarily have to store the above-mentioned file. That is, the above files are stored in an external device (a management device installed in a store (not shown), a cloud server existing outside the store, etc.), and the weighing device 20 accesses the external device as appropriate. And you may get the information in the file.

FIG. 6 is an example of a screen in the weighing device 20. The weighing device 20 displays a screen (weighing operation screen) as shown in FIG. 6 as an initial screen on the touch display 26, for example, before starting the weighing operation.

On the weighing operation screen shown in FIG. 6, a product name display column 1200, a unit price display column 1201, a tare display column 1202, a net amount / weighing value display column 1203, a selling price display column 1204, and various product buttons (product of product A) are displayed. Button 1210a, product button 1210b of product B, product button 1210c of product C, product button 1210d of product D, product button 1210e of product E), product search button 1211, various container buttons (my container button 1220, store container button 1230). ) Is placed.

The product name display field 1200 is a display field for displaying the product name. When a product is specified, the weighing device 20 displays the product name of the product in the product name display field 1200. For example, when a product is specified by operating the product button, the weighing device 20 displays the product name of the product in the product name display field 1200.

The unit price display column 1201 is a display column for displaying the unit price or the like per unit weight of the product. When a product is specified, the weighing device 20 displays the unit price of the product in the unit price display column 1201. For example, when a product is specified by operating the product button, the weighing device 20 displays the unit price of the product in the unit price display column 1201.

The tare display column 1202 is a display column for displaying the weight of the tare. When the weight of the tare is specified, the weighing device 20 displays the weight in the tare display column 1202. For example, when the weight of the My Container is read by the wireless tag reading unit, the weighing device 20 displays the weight in the tare display column 1202. Further, when the type of the store container is specified by operating the store container type button, the weighing device 20 displays the weight of the store container of the type in the tare display column 1202.

Information other than the weight of the tare can be displayed in the tare display column 1202. For example, in the tare display column 1202, the type of container and the recognition result of my container can also be displayed. In FIG. 19A, the wording “my container” is displayed in the tare display column 1202 as the type of container. In FIG. 19B, a mark “⊚” indicating that the tare has been recognized as a recognition result of the My Container is displayed in the tare display column 1202. In FIG. 19C, a mark “x” indicating that the tare is not recognized as a recognition result of the My Container is displayed in the tare display column 1202. In FIG. 21 (A), the wording “store container” is displayed as the type of container in the tare display column 1202. In FIG. 21C, the wording “container M” is displayed in the tare display column 1202 as the type of container.

The net amount / measurement value display column 1203 is a display column for displaying the net amount (net weight, net value) and the measurement value (total weight including tare value. Gross value). When a container (including a product) is placed on the platform 25a, the measuring device 20 displays the measured value of the container (including the product) in the net amount / measured value display column 1203. For example, as shown in FIG. 19B, the weighing device 20 reduces the measured value of the container (including the product) by putting parentheses in the net quantity / measured value display column 1203 (lower area in the same column). indicate. Further, when the weighing device 20 recognizes (acquires) both the measured value and the weight of the tare, the weighing device 20 calculates the net amount (calculated by subtracting the weight of the tare from the measured value), and the calculated net amount is calculated as the net amount. It is displayed in the measurement value display column 1203. For example, as shown in FIG. 19C, the weighing device 20 displays the calculated net amount in the net amount / measured value display column 1203 (center area in the same column).

The selling price display column 1204 is a display column for displaying the selling price of the product. When the weighing device 20 recognizes (acquires) both the unit price and the net amount of the product, it calculates the selling price (calculates by multiplying the unit price by the net amount), and displays the calculated selling price in the selling price display column 1204. ..

The product button 1210a of the product A is a button for designating (selecting) the product A. The same applies to the product button 1210b of the product B, the product button 1210c of the product C, the product button 1210d of the product D, and the product button 1210e of the product E. The product search button 1211 is a button for searching and designating a product, in addition to the designation by the product button.

The weighing device 20) to be mounted may be the same weighing device 20 or a different weighing device 20. As one aspect of the latter operation, for example, a weighing device 20 is installed at the service counter, a clerk registers my container 71 using the weighing device 20 installed at the service counter, and the weighing device 20 is installed in the weighing area. The customer may purchase the product using the My Container 71.

FIG. 9 is an example of a label printed and issued by the weighing device 20. After weighing each product (after calculating the selling price), the weighing device 20 prints and issues a label as shown in FIG. 9, for example, by the printing unit 28. FIG. 9A is a label when My Container is used. On the label of FIG. 9A, "My bottle" is printed as a notation indicating that My container has been used. That is, each store may refer to my container as my bottle. The 827 yen on the label in FIG. 9 (A) is the amount (847 yen) for the net amount (121 g) of the unit price (yen / 100 g) of 700 yen (original nut mix). This is a special price for my bottle with the discount amount (20 yen) discounted. Although not printed in the example of FIG. 9A, the discount amount of My Bottle (20 yen) may also be printed. The barcode on the label of FIG. 9A is, for example, a code of the above amount (847 yen). As will be described later, the price of container A is 30 yen, while the price of my bottle (my container), which is my personal property, is 0 yen, so it is explicitly stated as 0 yen for my bottle (my container). You may print on.

As a discount when using My Bottle, a predetermined amount (20 yen in the above case) is discounted from the total amount, but other discounts may be used. For example, the unit price may be discounted (that is, a predetermined percentage may be discounted from the total amount). The discount when using My Bottle is not essential.

FIG. 9B is a label when a store container is used. On the label of FIG. 9B, container A is printed as a notation indicating that the store container has been used. In this example, the price of the container A is 30 yen, so it is printed as 30 yen. The 877 yen on the label of FIG. 9 (B) is the amount obtained by adding the price of 30 yen for the container A to the 847 yen described in FIG. 9 (A). The barcode on the label of FIG. 9B is, for example, a code of the above amount (877 yen).

The barcode on the label is read, for example, by at least a device (not shown) capable of performing the registration process. That is, the customer puts the product in the container for purchase in the display area, moves to the weighing area with the container for purchasing containing the product, weighs the product using the weighing device 20, and as described above. After issuing a new label, move to the installation location of the device that can at least perform the registration process. The label issued by the measuring device 20 is preferably attached to a container (my container, store container). Further, at least in a device capable of executing the registration process, the bar code on the label may be read by the clerk or the customer himself. That is, at least in the device capable of executing the registration process, the registration process may be performed by the operation of the store clerk or by the customer's own operation.

FIG. 10 is a flowchart showing an example of the operation of the weighing device 20.

Then, the process returns to step S301 of FIG. If the situation does not change forever after returning to step S301 (when the situation of not recognizing my container continues), the processes of steps S301 to S321 will be repeatedly executed, but a predetermined time has elapsed. In that case, the process of calling the clerk may be executed without the operation of the customer.

The reasons why the My Container is not recognized as the My Container are, for example, damage to the wireless tag, failure of the reader (wireless tag reading unit 29), misreading of information, and the like. Also, even if it is not subject to management (when the data structure is different from the original one, such as the specifications of another store), at least my container is not recognized as my container.

In the case of a clerk call, after trying several more times, it may be refilled in a store container and sold (may be 0 yen), or my container may be registered again. Further, a predetermined ratio of the measured value may be input as the weight of the My Container. That is, as the tare weight when calculating the net value from the gloss value, a predetermined ratio (percentage) of the gloss value may be treated as the tare weight. The weighing device 20 executes a process (hereinafter, referred to as a percentage tare process) in which a predetermined ratio of the gloss value is used as the tare weight based on the operation of the clerk. For example, the weighing device 20 may display a button for executing the percentage tare processing, and may execute the percentage tare processing according to the operation of the button.

If it is determined that there is an answer (selection that my container is placed) that the placed container is not a store container (step S340: YES), the process proceeds to step S341. If it is determined that there is no response (selection that my container is placed) that the placed container is not a store container (step S340: NO), the process returns to step S330.

Step S341: The weighing device 20 displays a message indicating that the My container has not been recognized and a message prompting the user to reload the My container. Then, the process returns to step S301 of FIG. If the situation does not change forever after returning to step S301, the processes of steps S301 to S321 are repeatedly executed (since it was answered in step S340 that it is my container, the process returns to step S301. After that, step S320 (YES) is performed, and the processes of steps S301 to S321 are repeatedly executed), but when the predetermined time elapses, the clerk call process is executed even if there is no customer operation. It may be done.

Step S350: The weighing device 20 determines whether or not the type of store container has been selected. If it is determined that the type of store container has been selected (step S350: YES), the process proceeds to step S351. If it is determined that the store container type has not been selected (step S350: NO), the process returns to step S350 (that is, waits until the store container type is selected).

Step S351: The weighing device 20 acquires the weight information of the store container of the type as the weight information of the tare. Then, the process proceeds to step S352.

FIG. 43 is a 14th screen transition example in the weighing device 20. Specifically, FIG. 43 shows screens in some situations when the operation is performed in the order of placement (not recognizing my container) → answer to the effect that my container is placed.

(Operation example)
When the operation is performed in the order of mounting (not recognizing my container) → answering that my container is placed, the weighing device 20 operates as follows, for example, according to the flowcharts of FIGS. 11 to 17.

S100 (NO) → S101 (NO) → S200 (NO) → S201 (NO) → S202 (NO) → S211 (NO) → S230 (NO) → S300 (NO) → S301 (YES) → S302 → S303 → S310 (NO)-> S311 (NO)-> S320 (NO)-> S322 (NO)-> S323-> S330 (NO)-> S340 (YES)-> S341-> Omitted below

In FIG. 43 (D), a message indicating that the My container was not recognized and a message prompting the user to reload the My container are displayed (S341).

The timing at which the weighing device 20 reads the wireless tag is supplemented. The timing at which the measuring device 20 reads the wireless tag may be, for example, during fluctuation of the measured value (before stabilization) or after stabilization of the measured value (for example, immediately after stabilization). It may be after recognizing that the container has been placed by using a technique other than weighing such as image recognition. The timing of reading the wireless tag and the timing of determining whether or not the My Container has been recognized (step S311 in FIG. 16) do not necessarily have to be the same timing. That is, did the other one or more processes be executed after the wireless tag was read and the my container was recognized after the other one or more processes were executed without determining whether the my container was recognized immediately after reading the wireless tag? May be judged. In other words, the wireless tag may be read prior to determining whether or not the My Container has been recognized, instead of reading the wireless tag only when it is time to determine whether or not the My Container has been recognized.

Further, the wireless tag may be read when one or both of the condition of specifying the product and the condition of selecting the container (my container) are satisfied. In the example of the flowchart of FIGS. 11 to 17, even if both of the above conditions are not satisfied, it is possible to determine whether the container is My Container (that is, the wireless tag can be read) (FIG. 39, etc.).

The wireless tag reading unit 29 may continuously transmit radio waves for simplification of control. When the radio wave is constantly transmitted, the wireless tag reading operation may be turned off before the above condition relating to the timing of reading the wireless tag is satisfied, and turned on after the above condition is satisfied. This makes it possible to prevent accidental acquisition of unnecessary information (information on wireless tags of other My Containers existing in the vicinity) even if radio waves are constantly transmitted.

Although the embodiments have been described above, the above-described embodiment is an example, and the specific configuration is not limited to the above-described embodiment, and includes a design and the like within a range that does not deviate from the gist of the invention.

For example, in the above, the example in which the store container type button is displayed by transitioning to another screen after operating the store container button has been described, but the screen (same without transitioning to another screen) after operating the store container button. The store container type button may be displayed on the screen). Further, the store container type button may be displayed without displaying the store container button. That is, for example, the My Container button, the store container (container S) button, the store container (container M) button, and the store container (container L) button may be selectively displayed on the same screen.

Further, in the above, the weighing device 20 has described an example of calculating and displaying the net amount after all of the three orders of product identification, tare weight acquisition, and measurement value acquisition are completed ( In steps S400, S410, S420) of FIG. 11, even before the product is specified, if the acquisition of the tare weight and the acquisition of the measured value are completed, the net amount of the product before the specification is calculated and displayed. You may. For example, in FIG. 32 (D), FIG. 36 (B), etc., the net amount may be displayed.

Further, in the above description, the configuration in which the weighing device 20 executes communication (reading / writing information) with the wireless tag has been described, but another device different from the weighing device 20 executes communication with the wireless tag. However, the weighing device 20 may execute communication with the wireless tag via the other device. In other words, in the above description, the configuration in which the weighing device 20 includes the wireless tag reading unit 29 (the weighing device having the weighing function also has the wireless tag reading function) has been described, but the measuring device 20 includes the wireless tag reading unit 29. It may be composed of a non-weighing device and another device including the wireless tag reading unit 29 (separately composed of a weighing device having a weighing function and a device having a wireless tag reading function). That is, for example, the weighing system may be configured by the operation display unit, the weighing unit, and the wireless tag reading unit (may be configured as a weighing system that realizes each function (FIG. 3) of the weighing device 20 by a plurality of devices. good).

Further, in the above, the weighing device 20 used when registering the My Container and the weighing device 20 used when purchasing the product may be the same weighing device 20 or different weighing devices 20. Although it has been explained that it may be used, the measuring device 20 does not necessarily have to be used when registering the My Container. For example, the device for registering the My Container may have at least a weighing function, a wireless tag reading function, and an output function for outputting the completion of writing the tare mass.

Further, in the above, the weighing device 20 prints and issues the label (FIG. 9), but the device that prints and issues the label may be a separate body.

Further, although the example in which the weight information is written on the RFID label has been described above, the information written on the RFID label is not limited to the weight information. For example, in addition to the weight information, the registration date (registration date and time) and the registration expiration date (for example, one year from the time of registration) may be written. When the registered contents are confirmed (described later), the confirmation date (confirmation date and time) may be written. Further, information about the registered device (identification information that can identify the registered device) and information about the registered store (identification information that can identify the registered store, etc.) may be written. In addition, information (material, shape, color, etc.) regarding the characteristics of the My Container may be written. Information on the characteristics of the My Container may be obtained, for example, by displaying a screen provided with a selection field (option) at the time of registering the My Container and letting the registrant (clerk, customer) select it. Further, when registering My Container, for example, a serial number may be written as a control number. The serial number may be associated with customer information (membership number). Further, the membership number may be written as a management number.

Further, in the above, as the processes related to the My Container executed by the measuring device 20, the process of registering the unregistered My Container (see FIGS. 7 and 9) and the process of purchasing the product using the registered My Container. Although the processing (see FIGS. 8, 11 to 17, etc.) has been described, the processing related to the My Container executed by the measuring device 20 is not limited to the above two processing. For example, the weighing device 20 may execute a process of confirming the registered contents of the registered My Container. The following is an outline of the process for confirming the registered contents of the registered My Container.

(Outline of the process for confirming the registered contents of My Container)
(1) The weighing device 20 weighs the registered My container (a state in which no product is put) placed on the platform, and reads the weight information of the My container from the RFID label of the My container.
(2) The weighing device 20 compares the measured value (that is, the current weight of the My Container) with the weight information read from the RFID label (that is, the past (at the time of registration) weight of the My Container). Both (weighing value, weight information read from RFID label) should basically match, but for example, if my container is damaged or deteriorated, or if there is some kind of fraud (for example, my container at the time of registration). If there is a fraud that intentionally makes the item heavier, a fraud that replaces the RFID label on another My Container, etc.), the two will not match.
(3) The weighing device 20 outputs a comparison result between the two. For example, the weighing device 20 indicates that the registered contents (weight information read from the RFID label) are normal when the two match (or the difference between the two is within a predetermined tolerance). indicate. The measuring device 20 displays that the registered contents are abnormal when the two do not match (or when the difference between the two is outside the predetermined tolerance range). Further, when the two do not match, the weighing device 20 may rewrite the registered contents into a weighing value, for example, based on an operation.

As described above, in the case of writing the information on the date and time (registration date, expiration date of registration, confirmation date) on the RFID label, the measuring device 20 sets the registration contents of the My Container based on the information on the date and time. A message may be displayed to perform the confirmation process.

As described above, the weighing device 20 may output a part or all of the information written on the RFID label at the time of registration, or output information based on the information written on the RFID label. You may. As an example, when the weighing device 20 recognizes the My Container, the control number may be displayed in the tare display field 1202, or a label on which the control number is printed may be issued. Further, as described above, when the weighing device 20 recognizes the My Container, it displays a message to execute a process of confirming the registered contents of the My Container based on the information regarding the date and time of the registration expiration date. Alternatively, a label printed with the message may be issued.

(Writing to wireless tag at the time of sale)
In the above, the mode in which the information is read from the RFID label (more specifically, the wireless tag) at the time of purchasing the product using the My Container, but the information is not written on the RFID label has been described. That is, the mode in which the information is written on the RFID label when the My Container is registered but the information is not written on the RFID label when the product is purchased using the My Container has been described. However, the information may be written on the RFID label even when the product is purchased using the My Container.

For example, when purchasing a product using My Container, the selling price may be written on the RFID label. If the RFID label can be read at least in a device capable of performing the registration process (not shown), the weighing device 20 writes the selling price on the RFID label, and at least in the device capable of performing the registration process, via the RFID label. Since the selling price can be obtained, the product can be registered (and settled after registration) without printing and issuing the label (FIG. 9) on the measuring device 20. In addition, the weighing device 20 may write the product name of the product, information that can identify the product, the unit price of the product, the net amount, and the like.

Further, the weighing device 20 may write information such as the number of times of use and the amount of use, which is a purchase history, on the RFID label. That is, every time the My Container is used, the purchase information by the My Container is stored, and the My Container itself may manage (hold) the purchase history of the purchase using the My Container. Flexible (gradual) discounts can be implemented according to the purchase history. The purchase history may be stored in the outside of the My Container (for example, the measuring device 20, the management device (not shown), the cloud server, etc.) in association with the management number (serial number, membership number).

(Display of product button)
Further, in the above, an example in which the weighing device 20 displays the product button without particular limitation has been described, but the weighing device 20 is a product that is likely to be operated (designated) (that is, a customer containers in the display area). It is also possible to display the product button of the product (the product that can be regarded as taken out in the container) in (my container, store container) and not to display the product button of the product other than the product that is likely to be operated. This makes it easy to specify the product.

For example, it is possible to detect the product take-out operation in each display container (for example, display containers 300 and 400), and when the product take-out operation in a certain display container is detected, it means that the product has been taken out. The weighing device 20 may be notified. Specifically, the display container 300 includes a small device including a sensor unit that can detect the movement (tilt, rotation, etc.) of the own device and a communication unit that can output information to the outside (for example, the weighing device 20). Installed on the upper lid 310, when the upper lid 310 of a certain display container 300 is lifted, the weighing device 20 takes out the button corresponding to the product in the display container 300 and displays it as the button of the product that has been operated. You may. Similarly, the small device is installed in the pressing portion 410 of the display container 400, and when the pressing portion 410 of a certain display container 400 is pushed down, the weighing device 20 has a button corresponding to the product in the display container 400. May be displayed as a button of the product that has been taken out.

The weighing device 20 receives a notification for each product taking-out operation. When the weighing device 20 receives a plurality of notifications for a certain product, the product button of the product is displayed for the number of notifications (note that the display of the product button for one notification disappears by one operation). .. For example, when the product A is notified three times in a row (when the product A is taken out three times in a row), the weighing device 20 sets the number of times the product button of the product A is displayed three times. After the first operation of the product button of the product A, the product button of the product A is not erased after the second operation, and the product button of the product A is erased after the third operation. As a result, even when a plurality of customers take out a certain product in a relatively short period of time, the product buttons of the product can be continuously displayed for the number of the customers. If the interval between the take-out operations is short for a certain product (for example, when the take-out operation is detected again within a predetermined time), it may be determined that the product is taken out once.

In addition to the above-mentioned method, for example, an electronic product tag (a product tag having a detection function for detecting vibration and a communication function for the measuring device 20) is placed in the vicinity of each product, and the product tag is used. When a product tag in the vicinity of the product is touched as a purchase declaration of a certain product, the measuring device 20 may be notified that the purchase declaration has been made for the product.

The product buttons of products other than the products that are likely to be operated are also displayed, but the product buttons of the products that are likely to be operated are prioritized over the product buttons of the products that are not likely to be operated. It may be displayed (displayed in a position where it is easy to operate, displayed in a large size, displayed in a conspicuous color, etc.).

Further, in the above, after attaching the RFID label (label 80 with the wireless tag 81) to the My container, the My container to which the RFID label is attached is weighed and the measured value is written on the RFID label. (Fig. 7), the procedure for making a My container (registered My container) to which an RFID label on which a measured value is written is affixed is not limited to this. For example, an RFID label with a measured value written on it may be issued and then affixed to My Container.

(Structure 1) For example, a label issuing device including a wireless tag reading unit and an RFID label issuing unit that prints and issues an RFID label is prepared separately from the weighing device 20 (communication between the weighing device 20 and the label issuing device). It is possible). The weighing device 20 weighs my container and outputs (transmits) the measured value to the label issuing device. The label issuing device contains, for example, a roll-shaped RFID label inside, and writes the measured value input (received) from the measuring device 20 on one RFID label (leading RFID label). The label issuing device cuts and issues an RFID label on which a measured value is written by, for example, an auto-cut function (may be cut at a sewing machine line portion after issuing). In addition to writing the tare mass information (measured value) on the wireless tag 81, the label issuing device may print the tare mass information on the RFID label and issue it. Then, the RFID label issued as described above is affixed to the My Container weighed by the weighing device 20.

(Structure 2) The weighing device 20 may include an RFID label issuing unit. That is, in the above configuration (configuration 1), the weighing device 20 and the label issuing device exist as separate bodies, but they may be integrated. The weighing device 20 may include an RFID label issuing unit in addition to the printing unit 28, or the printing unit 28 may also have the function of the RFID label issuing unit. Further, the printing unit 28 may also have the function of the wireless tag reading unit. The weighing device 20 may separately include a wireless tag reading unit for registering my container and a wireless tag reading unit for purchasing a product, or includes one wireless tag reading unit used for both. You may.

The information to be written and the information to be printed may be appropriately set in the format setting or the like. Specifically, there are various usage methods such as writing the tare mass, registration date, store name, etc. on the wireless tag 81, and printing only the tare mass and the store name on the label 80 (common to configurations 1 and 2). ).

In the above, as shown in FIG. 1, the sales mode in which the customer himself puts the desired product in the container in the display area is illustrated, but the sales mode in which the clerk puts the product in the container may be used. For example, the clerk may put the products (side dishes, etc.) displayed in the showcase into the customer's own container according to the customer's order.
