Summary of the Invention

Problems to be Solved by the Invention

[0004] Of course, if the tare weight is not correctly registered (input) into the device, the net weight will not be correctly calculated. However, there is room for improvement in registering the tare weight, such as when the registration operation is incorrect or when it takes more time than necessary to avoid mistakes.

[0005] The present invention has been made in view of such circumstances, and an object thereof is to provide a technology capable of more suitably performing the registration of the tare weight.

Means for Solving the Problems

[0006] One aspect for solving the above-described problems is a registration device including product specifying means for specifying a product and tare selection means for receiving an operation of selecting a tare, wherein the tare selection means receives an operation of selecting a tare after the product is specified by the product specifying means.

Embodiment for Carrying Out the Invention

[0008] FIG. 1 is a diagram showing the state of a store where the sales system 1 is introduced. The store where the sales system 1 in this embodiment is introduced is, for example, as shown in FIG. 1, a store that sells food in a commercial facility (for example, department store, shopping center, inside a station, shopping street, etc.).

[0009] As shown in Fig. 1, various foods are displayed as products in the display case. A plurality of registration and settlement devices 10 (registration and settlement devices 10-1, 10-2, …) are installed on the display case. The registration and settlement device 10 includes a weighing platform 106a on which products to be weighed are placed. The inside of the display case is for store clerks (employees), and the outside is for customers. In Fig. 1, there is 1 store clerk (symbol S) and 2 customers (symbols C), but the number of people is for illustration purposes. The registration and settlement device 10 may also be referred to as a weighing and selling device, a metering value-added device, a sales data processing device, etc. The sales system 1 may also be referred to as a weighing and selling system, a metering value-added system, a sales data processing system, etc.

[0010] Fig. 2 is a diagram showing a configuration example of the sales system 1. As shown in Fig. 2, the sales system 1 includes a plurality of registration and settlement devices 10 (10-1, 10-2, …). Each registration and settlement device 10 can communicate with each other via a LAN (which may be wired or wireless).

[0011] The sales system 1 may include a store controller (not shown, in-store server) or a management device (not shown, personal computer). The registration and settlement device 10 can communicate with the store controller or the management device via a LAN. Also, the registration and settlement device 10 can communicate with an external device (for example, an external server installed at the head office or data center, which may be a cloud server) via another device (for example, a store controller, etc.) or without passing through another device.

[0012] Fig. 3 is a diagram showing a configuration example of the registration and settlement device 10. As shown in Fig. 3, the registration and settlement device 10 includes a CPU 101, a storage unit (ROM, RAM, HDD, SDD, etc.) 102, a display unit for store clerks 103, a display unit for customers 104, a scanner unit 105, a metering unit 106, an operation unit 107, a printing unit 108, a drawer 109, and a communication unit 110. The registration and settlement device 10 may further include a short-range communication unit (not shown).

[0013] The CPU 101 executes various processes (such as display control processes for various screens, arithmetic processes for total amounts, etc.) for realizing the functions of the registration and settlement device 10 by executing programs. The storage unit 102 stores various kinds of information. For example, it stores the programs executed by the CPU 101. Also, the storage unit 102 stores information acquired from the outside, information generated, referred to, etc. by the CPU 101 (for example, the information shown in FIG. 4, screen information, message information, print format information, identification information of its own device (device number)).

[0014] The clerk display unit 103 is arranged facing the clerk side. The clerk display unit 103 is configured as a touch display, displays various operation screens (FIGS. 5 to 34) for the clerk, and accepts various operations from the clerk. The customer display unit 104 is arranged facing the customer side. The customer display unit 104 displays various screens for the customer. The customer display unit 104 may be configured as a touch display and accept various operations from the customer.

[0015] The scanner unit 105 optically reads encoded information. For example, the scanner unit 105 reads barcodes or the like printed on the customer's membership card (or displayed on the customer's mobile terminal, etc.). When selling products with barcodes in the store, the scanner unit 105 reads the barcodes of the products.

[0016] The weighing unit 106 weighs the object (tare, products contained in the tare, etc.) placed on the weighing platform 106a and outputs data indicating the weighed value to the CPU 101. The tare is a container for containing products (a container that contains products and is placed on the weighing platform 106a). Note that the CPU 101 that has acquired the weighed value from the weighing unit 106 subtracts the weight of the tare (tare weight) from the weighed value (tare deduction) to calculate the weight of the product placed on the weighing platform 106a (purchase weight. The net weight of the product that the customer purchases).

[0017] The operation unit 107 is provided with various operation keys (numeric keys, cancellation key, cash register key, addition key, item number key, execution key, subtotal key, deposit / cash key, etc.) for receiving various operations from the store clerk. The operation keys are also referred to as mechanical keys, hardware keys, or hardware buttons. Note that all the operation keys may be arranged together (side by side), or at least one operation key may be arranged separately from the other operation keys. In other words, the operation unit 107 is a general term for one or more operation keys (regardless of the arrangement position).

[0018] Note that since the store clerk display unit 103 is configured as a touch display, the store clerk display unit 103 may also be referred to as an operation unit. The printing unit 108 prints a receipt and issues (outputs) it from the issuing port. Note that the printing unit 108 may print a label instead of or in addition to the receipt and issue (output) it from the issuing port.

[0019] The drawer 109 has a storage section for storing currency (banknotes, coins, etc.), and the storage section is configured to be pulled out to the front in response to the operation of the store clerk. The store clerk stores the currency received from the customer as payment in the drawer 109, and when there is change, takes out the currency corresponding to the amount of change from the drawer 109 and hands it to the customer. Coupons received from the customer may be stored in the drawer 109.

[0020] The communication unit 110 communicates with other devices (for example, other registration and settlement devices 10). The communication by the communication unit 110 is communication via a wired or wireless LAN, but communication may be performed by other communication methods.

[0021] (Basic operation of the registration and settlement device 10) The store clerk receives an instruction (order) for purchasing goods (purchased goods, purchased weight, etc.) from the customer. The store clerk who has received an instruction for purchasing goods from the customer operates the registration and settlement device 10 as follows, for example. In other words, the registration and settlement device 10 operates as follows based on the operation of the store clerk who has received an instruction for purchasing goods from the customer.

[0022] (Identification of purchased goods) The store clerk identifies the customer's purchased items (the items instructed by the customer) using the registration settlement device 10. For example, the store clerk operates a single item selection button to identify the item. The item selection button is a button capable of identifying the item name and unit price of each individual item (for example, for an item with a measurement category of "0 (indeterminate kan)" described later, the price per 100 g, and for an item with a measurement category of "1 (fixed amount)", the price per item) (for example, the item ID (described later) of each individual item is associated with the item selection button). For example, the registration settlement device 10 displays the item selection buttons corresponding to each item (the item selection buttons capable of identifying the item name and unit price of each individual item) on the store clerk display unit 103, and the store clerk operates the item selection button corresponding to the customer's purchased item to identify the customer's purchased item.

[0023] In addition, the registration settlement device 10 displays the item name and unit price of the identified purchased item on the store clerk display unit 103 and the customer display unit 104.

[0024] (Specification (Registration) of tare weight) The store clerk identifies the tare weight of the tare containing the customer's purchased item using the registration settlement device 10 and registers it in the registration settlement device 10. Three methods are prepared for identifying the tare weight: button selection, setting input, and tare weighing. In other words, the registration settlement device 10 has three functions for identifying the tare weight: button selection, setting input, and tare weighing, and registers the tare weight by any of these functions.

[0025] (Button selection) "Button selection" is a method (function) of identifying the tare weight using the tare selection button. The tare selection button is a button capable of identifying the tare weight of each individual tare (for example, the tare ID (described later) of each individual tare is associated with the tare selection button). The registration settlement device 10 displays the tare selection buttons for each tare (the tare selection buttons capable of identifying the tare weight of each individual tare) on the store clerk display unit 103, and the store clerk operates the tare selection button for the tare containing the customer's purchased item. (Setting input) The setting input is a method (function) for specifying the tare weight by setting input. The registration and settlement device 10, for example, displays a screen for receiving setting input on the clerk display unit 103, and the clerk inputs the tare weight of the tare containing the customer's purchased goods on the screen by setting input. (Tare weighing) Tare weighing is a method (function) for specifying the tare weight by weighing the tare (empty tare). The registration and settlement device 10, for example, displays a button for receiving a declaration of tare weighing on the clerk display unit 103, and after the clerk operates the button, places the tare (empty tare) containing the customer's purchased goods on the weighing platform 106a.

[0026] Note that the registration and settlement device 10 displays the tare weight specified (registered) by button selection, setting input, or tare weighing on the clerk display unit 103 and the customer display unit 104.

[0027] When specifying the tare weight by button selection or when specifying the tare weight by setting input, it is not necessary for the tare to be empty when specifying the tare weight (when operating the tare selection button, when inputting the tare weight by setting). That is, when specifying the tare weight by button selection or when specifying the tare weight by setting input, it is possible to specify the tare weight even when the tare contains goods (the tare weight may be specified after the goods are placed in the tare). Also, even when specifying the tare weight by tare weighing, if a tare (empty tare) of the same type as the tare containing the goods is weighed, the tare weight can be specified. That is, when specifying the tare weight by tare weighing after the goods are placed in the tare, a tare (empty tare) of the same type as the tare may be weighed.

[0028] (Specification (registration) of purchase weight) The clerk specifies the customer's purchase weight (the purchase weight instructed by the customer) with the registration and settlement device 10 and registers it in the registration and settlement device 10. For example, the clerk places the purchased goods in the tare and places it on the weighing platform 106a, and the registration and settlement device 10 subtracts the tare weight from the measured value (tare weight + weight of the purchased goods) to specify (calculate) the purchase weight.

[0029] Note that the registration settlement device 10 displays the specified (registered) purchase weight on the clerk display unit 103 and the customer display unit 104. Also, for products with a measurement category of "0 (indeterminate kan)", the registration settlement device 10 calculates the selling price from the purchase weight and the unit price (the unit price of the purchased product) and displays it on the clerk display unit 103 and the customer display unit 104. Further, for products with a measurement category of "1 (fixed amount)", the registration settlement device 10 calculates the selling price from the unit price (the unit price of the purchased product) and the number of purchases.

[0030] (Settlement) After the registration settlement device 10 finishes calculating the selling price, the clerk operates the registration settlement device 10 to proceed with the settlement operation, for example, by operating the subtotal button. Based on the operation to proceed with the settlement (operation of the subtotal button), the registration settlement device 10 displays a settlement screen for settlement and executes a settlement process based on the clerk's operations (for example, operation of the deposit / cash button, input of the deposit amount, etc.) to complete the settlement (that is, the transaction of the purchased product).

[0031] (Basic operation flow) The basic flow of operations by the clerk is: specifying the purchased product → specifying the tare weight → specifying the purchase weight → settlement. That is, the registration settlement device 10 specifies the purchased product, then specifies the tare weight, then specifies the purchase weight, calculates the selling price, and then executes the settlement.

[0032] Note that the basic flow of operations by the clerk is not limited to the above flow. For example, it may be: specifying the tare weight → specifying the purchased product → specifying the purchase weight → settlement. That is, either the specification of the tare weight or the specification of the product may come first.

[0033] Figure 4 shows an example of various types of information. In the sales system 1, various types of information as shown in Figure 4 are managed. For example, the registration settlement device 10 stores various types of information as shown in Figure 4 in the storage unit 102.

[0034] FIG. 4(A) is an example of a product master (product file). FIG. 4(B) is an example of a classification master (classification file). FIG. 4(C) is an example of a tare master (tare file). FIG. 4(D) is another example of a product master (product file). FIG. 4(E) is an example of a recommended tare setting file. FIG. 4(F) is another example of a recommended tare setting file.

[0035] The product master is a file related to products. The product master in FIG. 4(A) includes items such as product ID, measurement category, product name, unit price, classification ID, recommended tare, and other tare selection category.

[0036] The product ID is product identification information (product code) that identifies a product. In the item "product ID" of the product master in FIG. 4(A), the product IDs of each product (all products handled in the sales system 1) are stored. The product name is the name of the product. In the item "product name" of the product master in FIG. 4(A), the product names of each product are stored.

[0037] The measurement category is a category related to measurement. In the item "measurement category" of the product master in FIG. 4(A), the measurement categories of each product are stored. The value "0" of the measurement category is indefinite weight, and the value "1" is fixed amount. The unit price is the unit price of the product. In the item "unit price" of the product master in FIG. 4(A), the unit prices of each product are stored. The unit price of a product with a measurement category of "0 (indefinite weight)" is, for example, the price per 100g, and the selling price of a product with a measurement category of "0 (indefinite weight)" is calculated from the unit price and the purchased weight. The unit price of a product with a measurement category of "1 (fixed amount)" is the price per piece, and the selling price of a product with a measurement category of "1 (fixed amount)" is calculated from the unit price and the purchased quantity. That is, a product with a measurement category of "0 (indefinite weight)" is a product whose selling price is determined by measurement, while a product with a measurement category of "1 (fixed amount)" is a product whose selling price is determined by the quantity.

[0038] The classification ID is classification identification information (classification code) that identifies the classification (group) to which a product belongs. In the item "classification ID" of the product master in FIG. 4(A), the classification IDs of the classifications to which each product belongs are stored.

[0039] The recommended bag is the bag recommended to be used. In the item "Recommended bag" of the product master in Fig. 4(A), the bag ID (bag identification information (bag code) for identifying the bag) of the bag recommended to be used for each product is stored.

[0040] The other bag selection classification is the classification regarding the selection of other bags (bags other than the recommended bag) (specifically, the selection by the bag selection button). The value "0" of the other bag selection classification permits the selection of other bags, and the value "1" prohibits the selection of other bags. In the item "Other bag selection classification" of the product master in Fig. 4(A), the value of the other bag selection classification for each product is stored.

[0041] The classification master is a file regarding classification. The classification master in Fig. 4(B) includes items of classification ID and classification name. The classification ID is classification identification information (classification code) for identifying the classification (group). In the item "Classification ID" of the classification master in Fig. 4(B), the classification ID of each classification (all classifications handled in the sales system 1) is stored. The classification name is the name of the classification. In the item "Classification name" of the classification master in Fig. 4(B), the classification name of each classification is stored.

[0042] The bag master is a file regarding the bag (container). The bag master in Fig. 4(C) includes items of bag ID, bag name, and bag weight. The bag ID is bag identification information (bag code) for identifying the bag. In the item "Bag ID" of the bag master in Fig. 4(C), the bag ID of each bag (all bags handled in the sales system 1) is stored. The bag name is the name of the bag. In the item "Bag name" of the bag master in Fig. 4(C), the bag name of each bag is stored. The bag weight is the weight of the bag. In the item "Bag weight" of the bag master in Fig. 4(C), the bag weight of each bag is stored.

[0043] According to the product master in Fig. 4(A), the classification master in Fig. 4(B), and the tare weight master in Fig. 4(C), for example, prepared food A (product ID "S001") is classified as a stew (classification ID "B01"), and the small white square with a tare weight of 8 g (tare weight ID "F001"), the medium white square with a tare weight of 10 g (tare weight ID "F002"), and the large white square with a tare weight of 13 g (tare weight ID "F003") are recommended as the tare weights to be used (set as the recommended tare weights), and the selection of other tare weights other than the recommended tare weights is permitted (value of the other tare weight selection category "0"). Also, for example, prepared food C (product ID "S003") is classified as a fried food (classification ID "B02"), and the small white circle with a tare weight of 10 g (tare weight ID "F004"), the medium white circle with a tare weight of 14 g (tare weight ID "F005"), and the large white circle with a tare weight of 18 g (tare weight ID "F006") are recommended as the tare weights to be used (set as the recommended tare weights), and the selection of other tare weights other than the recommended tare weights is prohibited (value of the other tare weight selection category "1").

[0044] Note that the master may be managed (stored) separately in two or more parts. For example, the product master in Fig. 4(A) may be managed (stored) separately into the product master in Fig. 4(D) and the recommended tare weight setting file in Fig. 4(E). The recommended tare weight setting file in Fig. 4(F) will be described later.

[0045] Note that it has been described that the various types of information shown in FIG. 4 are managed in the sales system 1, and as an example, it has been described that the registration and settlement device 10 stores the various types of information shown in FIG. 4 in the storage unit 102. However, it may be set (registered) in any device of the sales system 1 and shared in all devices that refer to each piece of information within the sales system 1. The device for setting various types of information and the device for storing various types of information are not particularly limited. For example, in one registration and settlement device 10 (e.g., registration and settlement device 10-1) that is the representative (parent device), a product master (FIGS. 4(A) and 4(D)) and a recommended tax-included price setting file (FIGS. 4(E) and 4(F)) are set and stored in the storage unit 102. Other registration and settlement devices 10 (such as registration and settlement device 10-2) may receive the product master and the recommended tax-included price setting file from the representative registration and settlement device 10 and store them in the storage unit 102, or may refer to the product master and the recommended tax-included price setting file stored in the storage unit 102 of the representative registration and settlement device 10. In the store controller (in-store server), management device (personal computer), or external device (external server, cloud server), a product master and a recommended tax-included price setting file may be set and transmitted (distributed) to each registration and settlement device 10, and each registration and settlement device 10 may store the received product master, etc. in the storage unit 102. Also, the device (such as the store controller or management device) that sets the product master and the recommended tax-included price setting file may store them in its own storage unit, and each registration and settlement device 10 may refer to the product master, etc. stored in the storage unit. The same applies to the classification master (FIG. 4(B)) and the tax-included price master (FIG. 4(C)).

[0046] That is, a function of pre-setting the recommended tax-included price for each product (recommended tax-included price pre-setting function), a function of pre-setting the other tax-included price selection category for each product (other tax-included price selection category pre-setting function), and a function of storing the above pre-set content for each product (setting information storage function. Specifically, a function of storing a product master and a recommended tax-included price setting file) may be possessed by any device within the sales system 1.

[0047] (Display on the clerk display unit 103) FIGS. 5 to 34 are display examples on the clerk display unit 103 of the registration and settlement device 10. The registration and settlement device 10 displays various screens for the store staff. For example, after power-on, the registration and settlement device 10 displays a menu screen (not shown), and when the store staff operates the registration button on the menu screen, it displays a registration screen (initial screen) as shown in FIG. 5.

[0048] At the upper part of the registration screen in FIG. 5 (the same applies to other registration screens), there is a display area for displaying the tare weight, product name, purchased weight, unit price, selling price, total points, total amount (price), etc. At the upper right of the center of the registration screen in FIG. 5 (the same applies to other registration screens), there are buttons (buttons corresponding to the tabs, buttons under the tabs) that can be switched by a plurality of selectable tabs (cooked food tab, leafy vegetable tab, root vegetable tab, sweets tab) by operation (touch). In FIG. 5, the cooked food A button, cooked food B button, cooked food C button, cooked food D button, and cooked food E button corresponding to the cooked food tab are displayed. The cooked food A button, cooked food B button, cooked food C button, cooked food D button, and cooked food E button are all product selection buttons. Also, the cooked food tab, leafy vegetable tab, root vegetable tab, and sweets tab may be referred to as product tabs.

[0049] In addition, as buttons under the product tab, buttons other than the product selection button (for example, the tare selection button) may be displayed. Also, as selectable tabs, tabs other than the product tab (for example, the tare tab described later) may be provided. As buttons under the tare tab, buttons other than the tare selection button (for example, the other selection button and the other tare (different method) button described later) may be displayed.

[0050] Note that although the tab switches according to the operation of the store staff, the registration and settlement device 10 may automatically switch the tab according to the progress of the process.

[0051] At the lower part of the registration screen in FIG. 5 (the same applies to other registration screens and settlement screens), there are a tare button to be operated when specifying the tare weight by setting input or tare weighing, a zero button to be operated when performing zero reset, a cancel button to be operated when canceling the previous operation, etc., a subtotal button to be operated when proceeding to settlement, and a deposit / cash button to be operated when finalizing the deposit amount.

[0052] In addition, on the registration screen shown in FIG. 5 (the same applies to other registration screens and settlement screens), the buttons indicated by solid line frames (for example, the side dish A button to the side dish E button, the tare button, etc.) are buttons for which operations are valid (operable buttons), and the buttons indicated by broken line frames (for example, the cancel button, the subtotal button, etc.) are buttons for which operations are invalid (non-operable buttons). Buttons for which operations are invalid (non-operable buttons) may be grayed out or hidden. In addition, buttons for which operations are invalid may display an error message after the operation.

[0053] FIGS. 5 to 11 (transition: FIG. 5 → FIG. 6 → FIG. 7 → FIG. 8 → FIG. 9 → FIG. 10 → FIG. 11) show display examples (registration to settlement display examples) for side dish A, which is a product for which the value of the other tare selection category is "0 (permitted)", that is, a product for which selection of a tare other than the recommended tare by the tare selection button is permitted, when the recommended tare is selected by the tare selection button (when the tare weight of the recommended tare is specified by the tare selection button).

[0054] On the registration screen (initial screen) of FIG. 5, for example, a store clerk who has received an instruction from a customer to purchase a product (side dish A, 150 g) operates the side dish A button.

[0055] When the side dish A button on the registration screen of FIG. 5 is operated, the registration and settlement device 10 pops up and displays a small screen (tare selection screen) SG1 as shown in FIG. 6. The small screen SG1 (the same applies to the small screen SG2 and the small screen SG3 described later) is a screen for button selection (for specifying the tare weight by the tare selection button).

[0056] On the small screen SG1 of FIG. 6, a small white square button (8 g) displayed as "Small white square (8 g)", a medium white square button (10 g) displayed as "Medium white square (10 g)", a large white square button (13 g) displayed as "Large white square (13 g)", and an other selection button displayed as "Other selection" are displayed. The small white square button, the medium white square button, and the large white square button are all tare selection buttons. The other selection button is a button for selecting other tare selection buttons.

[0057] The tare selection buttons (small white square button, medium white square button, large white square button) on the small screen SG1 in Fig. 6 are tare selection buttons for selecting the respective recommended tares (small white square, medium white square, large white square) of the vegetable A. The other selection buttons on the small screen SG1 in Fig. 6 are buttons for selecting tares other than the recommended tares (small white square, medium white square, large white square) of the vegetable A.

[0058] That is, when the vegetable A button is operated, the registration settlement device 10 refers to the product master in Fig. 4(A) (or refers to the recommended tare setting file in Fig. 4(E)), and based on the recommended tares (tare IDs "F001", "F002", "F003") of the vegetable A (product ID "S001") and the other tare selection classification "0 (permission)", it pops up and displays the small screen SG1 having a small white square button, a medium white square button, a large white square button, and other selection buttons.

[0059] For example, when the store clerk puts (or has put) the vegetable A (150 g) into the medium white square, which is one of the recommended tares (small white square, medium white square, large white square) of the vegetable A, the clerk operates the medium white square button on the small screen SG1 in Fig. 6.

[0060] When the medium white square button on the small screen SG1 in Fig. 6 is operated, the registration settlement device 10 erases the small screen SG1 and displays a registration screen as shown in Fig. 7. Since the tare weight (10 g) is determined by the operation of the tare selection button (medium white square button), the operation of the tare button is invalid on the registration screen in Fig. 7.

[0061] Also, on the registration screen of Fig. 7 (the same applies to the registration screen on the back of the small screen SG1 in Fig. 6), since the selection of the product (prepared food A) has already been completed, the operations of all the product selection buttons (prepared food A button to prepared food E button) are disabled. However, the product selection button (prepared food A button) of the selected product (prepared food A) and the product selection buttons (prepared food B button to prepared food E button) of the unselected products (prepared food B to prepared food E) are displayed discriminably (shown as a thick dashed-line frame in the figure). The same applies to the registration screen of Fig. 13 (the same applies to the registration screen on the back of the small screen SG2 in Fig. 12), the registration screen of Fig. 15 (the same applies to the registration screen on the back of the small screen SG3 in Fig. 14), and so on.

[0062] Note that by a predetermined operation (for example, the operation of the cancel button), it is possible to correct (re-identify) the purchased product and the tare weight. For example, when there is an operation of the cancel button on the registration screen of Fig. 7, the registration device 10 displays the registration screen of Fig. 5 (initial screen) (that is, it makes it possible to select a product, select a button, input a setting number, or identify the tare weight by tare weighing).

[0063] Instead of the above, when there is an operation of the cancel button on the registration screen of Fig. 7, the registration device 10 may display the registration screen of Fig. 6 (the front is the small screen SG1) (that is, it may make it possible to identify the tare weight by tare weighing). A cancel button is arranged on the small screen SG1 of Fig. 6, and when there is an operation of the cancel button on the small screen SG1 of Fig. 6, the registration device 10 may display the registration screen of Fig. 5 (initial screen).

[0064] Instead of the above, when there is an operation of the cancel button on the registration screen of Fig. 7, the registration device 10 may clear the tare weight (10 g → 0 g) on the registration screen of Fig. 7 and enable the tare button and the zero button (that is, it may make it possible to identify the tare weight by setting input or tare weighing).

[0065] Subsequently, the store clerk places the prepared food A (150 g by visual estimate) into the white square selected on the small screen SG1 and places it on the weighing platform 106a. Note that the store clerk may operate the button in the white square on the small screen SG1 after placing the prepared food A (150 g by visual estimate) into the white square and then place it on the weighing platform 106a.

[0066] When the prepared food A placed in the white square is placed on the weighing platform 106a and the weight stabilizes, the registration device 10 displays a registration screen as shown in Fig. 8. Assume that the measured value ( tare weight + weight of the purchased product) of the prepared food A placed in the white square was 160 g. The registration device 10 subtracts the tare weight (10 g) in the white square from the measured value (160 g) to calculate the purchased weight (150 g), and calculates the selling price (600 yen) from the unit price of the prepared food A (400 (yen / 100 g)) and the purchased weight (150 g). Since the selling price has been determined, the operation of the subtotal button is enabled on the registration screen of Fig. 8.

[0067] Subsequently, the store clerk checks the purchased weight, selling price, etc. on the registration screen of Fig. 8, and if there are no problems, operates the subtotal button.

[0068] When the subtotal button on the registration screen of Fig. 8 is operated, the registration device 10 displays a settlement screen (subtotal screen) as shown in Fig. 9. On the settlement screen of Fig. 9, the operation of the deposit / cash button is enabled.

[0069] Subsequently, the store clerk checks the purchased products, subtotal amount, etc. on the settlement screen of Fig. 9, and if there are no problems, operates the deposit / cash button.

[0070] When the deposit / cash button on the settlement screen of Fig. 9 is operated, the registration device 10 pops up and displays a small screen (deposit amount input screen) SG5 as shown in Fig. 10.

[0071] Subsequently, the store clerk receives cash (for example, 700 yen) from the customer that is equal to or more than the total amount, enters the deposit amount (for example, 700) in the small screen SG5, and operates the confirm button.

[0072] When the deposit amount (700 yen) is entered and the confirm button is operated on the small screen SG5 in FIG. 10, the registration calculator 10 erases the small screen SG5 and displays a settlement screen (settlement completion screen) as shown in FIG. 11. A message "You can register the next customer" indicating that the next customer (the next customer's purchased product) can be registered is displayed on the settlement screen in FIG. 11 as guidance information for the clerk. When a predetermined time (for example, 5 seconds) has elapsed, the registration calculator 10 displays the registration screen (initial screen) in FIG. 5.

[0073] FIGS. 12 and 13 (transition: FIG. 5 → FIG. 6 → FIG. 12 → FIG. 13) show display examples (display examples up to the middle) when, for a prepared food A, which is a product for which the value of the other tare selection category is "0 (permitted)", that is, a product for which selection of a tare other than the recommended tare by the tare selection button is permitted, a tare other than the recommended tare is selected by the tare selection button (when the tare weight of a tare other than the recommended tare is specified by the tare selection button).

[0074] On the small screen SG1 in FIG. 6, for example, when the clerk puts (or has put) prepared food A (150 g) in a tare other than the recommended tares (small white square, medium white square, large white square) of prepared food A, the clerk operates the other selection button.

[0075] When the other selection button on the small screen SG1 in FIG. 6 is operated, the registration calculator 10 pops up and displays a small screen (tare selection screen) SG2 as shown in FIG. 12 instead of the small screen SG1. On the small screen SG2 in FIG. 12, tare selection buttons (small white circle button, medium white circle button, large white circle button, small transparent square button, etc.) for selecting each of the tares other than the recommended tares (small white square, medium white square, large white square) of prepared food A and a return button for returning to the small screen SG1 (displaying the small screen SG1 instead of the small screen SG2) are arranged.

[0076] For example, when the clerk puts (or has put) prepared food A (150 g) in the medium white circle, the clerk operates the medium white circle button on the small screen SG2 in FIG. 12.

[0077] When there is an operation on the button in the white square of the small screen SG2 in Fig. 12, the registration calculator 10 erases the small screen SG2 and displays a registration screen as shown in Fig. 13. Since the tare weight (14 g) is determined by the operation of the tare selection button (the button in the white circle), the operation of the tare button is invalid on the registration screen of Fig. 13.

[0078] When there is an operation on the cancel button on the registration screen of Fig. 13, the registration calculator 10 displays the registration screen of Fig. 5 (initial screen). When there is an operation on the cancel button on the registration screen of Fig. 13, the registration calculator 10 may display the registration screen of Fig. 12 (the front has the small screen SG2). A cancel button is arranged on the small screen SG2 of Fig. 12, and when there is an operation on the cancel button of the small screen SG2 of Fig. 12, the registration calculator 10 may display the registration screen of Fig. 5 (initial screen), or may display the registration screen of Fig. 6 (the front has the small screen SG1). Further, when there is an operation on the cancel button on the registration screen of Fig. 13, the registration calculator 10 may clear the tare weight (14 g → 0 g) on the registration screen of Fig. 13 and enable the tare button and the zero button.

[0079] Subsequently, the store clerk puts the mixed vegetables A into the white circle selected on the small screen SG2 (put 150 g by visual estimate) and places it on the weighing platform 106a. The store clerk may operate the button in the white circle on the small screen SG2 after putting the mixed vegetables A into the white circle (after putting 150 g by visual estimate) and then place it on the weighing platform 106a.

[0080] Since the display of the registration calculator 10 after placing the mixed vegetables A contained in the white circle on the weighing platform 106a is the same as the display in Figs. 8 to 11, the description is omitted.

[0081] Figs. 14 and 15 (transition: Fig. 5 → Fig. 14 → Fig. 15) show display examples (display examples up to the middle) when the recommended tare is selected by the tare selection button for the mixed vegetables C, which is a product with the value of "1 (prohibited)" in the other tare selection category, that is, a product in which the selection of a tare other than the recommended tare by the tare selection button is prohibited.

[0082] On the registration screen (initial screen) of FIG. 5, for example, a store clerk who has received an instruction from a customer to purchase a product (prepared food C, 100 g) operates the prepared food C button.

[0083] When there is an operation on the prepared food C button on the registration screen of FIG. 5, the registration and settlement device 10 pops up and displays a small screen (windbag selection screen) SG3 as shown in FIG. 14. On the small screen SG3 of FIG. 14, a small white round button, a medium white round button, a large white round button, and an other windbag (different method) button are displayed. The small white round button, the medium white round button, and the large white round button are all windbag selection buttons. The other windbag (different method) button is a button for specifying the windbag weight by a method other than button selection (inputting setting values, weighing the windbag).

[0084] That is, when there is an operation on the prepared food C button, the registration and settlement device 10 refers to the product master of FIG. 4(A) (or refers to the recommended windbag setting file of FIG. 4(E)), and based on the recommended windbags (windbag IDs "F004", "F005", "F006") of prepared food C (product ID "S003") and the other windbag selection classification "1 (prohibited)", it pops up and displays a small screen SG3 having a small white round button, a medium white round button, a large white round button, and an other windbag (different method) button.

[0085] For example, when the store clerk puts (or has put) prepared food C (100 g) into the large white round, which is one of the recommended windbags (small white round, medium white round, large white round) of prepared food C, the store clerk operates the large white round button on the small screen SG3 of FIG. 14.

[0086] When there is an operation on the large white round button on the small screen SG3 of FIG. 14, the registration and settlement device 10 erases the small screen SG3 and displays a registration screen as shown in FIG. 15. Since the windbag weight (18 g) has been determined by the operation of the windbag selection button (large white round button), the operation of the windbag button is disabled on the registration screen of FIG. 15.

[0087] In addition, when an operation is performed on the cancel button on the registration screen of Fig. 15, the registration calculation device 10 displays the registration screen (initial screen) of Fig. 5. When an operation is performed on the cancel button on the registration screen of Fig. 15, the registration calculation device 10 may display the registration screen of Fig. 14 (the front is the small screen SG3). A cancel button is arranged on the small screen SG3 of Fig. 14, and when an operation is performed on the cancel button of the small screen SG3 of Fig. 14, the registration calculation device 10 may display the registration screen (initial screen) of Fig. 5. Further, when an operation is performed on the cancel button on the registration screen of Fig. 15, the registration calculation device 10 clears the tare weight (18 g → 0 g) on the registration screen of Fig. 15 and enables the tare button and the zero button.

[0088] Subsequently, the store clerk places the mixed vegetables C in the large white circle selected on the small screen SG3 (containing 100 g by visual measurement) and places it on the weighing platform 106a. Note that the store clerk may operate the large white circle button on the small screen SG3 after placing the mixed vegetables C in the large white circle (after containing 100 g by visual measurement) and then place it on the weighing platform 106a.

[0089] Since the display of the registration calculation device 10 after placing the mixed vegetables C contained in the large white circle on the weighing platform 106a is the same as the display in Figs. 8 to 11, the description is omitted.

[0090] Figs. 16 and 17 (transition: Fig. 5 → Fig. 14 → Fig. 16 → Fig. 17) show display examples (display examples up to the middle) when, for the mixed vegetables C, which are products with the value of the other tare selection category being "1 (prohibited)", that is, products in which the selection of a tare other than the recommended tare by the tare selection button is prohibited, the recommended tare is not selected by the tare selection button, that is, when the tare weight is specified by setting or weighing.

[0091] On the small screen SG3 of Fig. 14, for example, when the store clerk places the mixed vegetables C (100 g) in a tare other than the recommended tares (small white circle, medium white circle, large white circle) of the mixed vegetables C, the store clerk operates the other tare (different method) button.

[0092] When there is an operation on the other windbag (different method) button of the small screen SG3 in Fig. 14, the registration settlement device 10 pops up and displays a small screen (windbag input screen) SG4 as shown in Fig. 16 instead of the small screen SG3. The small screens SG1 to SG3 are screens for button selection (for specifying the windbag weight by the windbag selection button), while the small screen SG4 is a screen for setting value input (for specifying the windbag weight by setting value input) and windbag weighing (for specifying the windbag weight by windbag weighing). In the part for setting value input on the small screen SG4, there are a numeric keypad (number buttons), a clear button, an OK button, etc. In the part for windbag weighing on the small screen SG4, there is a weighing button.

[0093] (When specifying the windbag weight by setting value input) For example, the store clerk inputs the windbag weight (e.g., 13 g) as a setting value on the small screen SG4 in Fig. 16 and operates the OK button. When the windbag weight (13 g) is input as a setting value and the OK button is operated on the small screen SG4 in Fig. 16, the registration settlement device 10 erases the small screen SG4 and displays a registration screen as shown in Fig. 17.

[0094] (When specifying the windbag weight by windbag weighing) For example, the store clerk operates the weighing button on the small screen SG4 in Fig. 16, places the large empty white square (13 g) on the weighing platform 106a, and operates the windbag button after the weight stabilizes. When there is an operation on the weighing button on the small screen SG4 in Fig. 16, the registration settlement device 10 erases the small screen SG4, and when there is an operation on the lower windbag button, it displays a registration screen as shown in Fig. 17. When there is an operation on the weighing button, the registration settlement device 10 may erase the small screen SG4 and prompt the store clerk to place an empty windbag on the weighing platform 106a (for example, display a message such as "Please place an empty container").

[0095] Subsequently, the store clerk places the prepared side dish C (100 g by visual measurement) into the tare bag whose tare weight has been specified by inputting the number of items (or the tare bag whose tare weight has been specified by weighing the tare bag), and places it on the weighing platform 106a. Note that the store clerk may input the number of items on the small screen SG4 after placing the prepared side dish C into the tare bag (after placing 100 g by visual measurement) (or may weigh the same type of empty tare bag).

[0096] Since the display of the registration and settlement device 10 after placing the prepared side dish C contained in the tare bag whose tare weight has been specified by inputting the number of items (or the tare bag whose tare weight has been specified by weighing the tare bag) on the weighing platform 106a is the same as the display in FIGS. 8 to 11, the description thereof is omitted.

[0097] Note that when an operation of the cancel button is performed on the registration screen in FIG. 17, the registration device 10 displays the registration screen (initial screen) in FIG. 5. When an operation of the cancel button is performed on the registration screen in FIG. 17, the registration device 10 may display the registration screen in FIG. 14 (the front is the small screen SG3), or may display the registration screen in FIG. 16 (the front is the small screen SG4). A cancel button is arranged on the small screen SG4 in FIG. 16. When an operation of the cancel button on the small screen SG4 is performed, the registration device 10 may display the registration screen (initial screen) in FIG. 5, or may display the registration screen in FIG. 14 (the front is the small screen SG3). Further, when an operation of the cancel button is performed on the registration screen in FIG. 17, the registration device 10 clears the tare weight (13 g → 0 g) on the registration screen in FIG. 17, and may enable the tare bag button and the zero button.

[0098] (Example of display of registration screen provided with tare bag tab) Instead of the registration screen (initial screen) in FIG. 5, the registration device 10 may display a registration screen (initial screen) as shown in FIG. 18. A plurality of product tabs (prepared side dish tab, leafy vegetable tab, root vegetable tab, sweets tab) are provided on the registration screen in FIG. 5, while a tare bag tab is further provided on the registration screen in FIG. 18.

[0099] Figures 18 to 20 (transition from Figure 18 → Figure 19 → Figure 20) show examples of displays (intermediate display examples) when the recommended air bag is selected by the air bag selection button for product A, which is a product where the value of the other air bag selection category is "0 (permitted)", that is, a product where selection of an air bag other than the recommended air bag by the air bag selection button is permitted.

[0100] On the registration screen (initial screen) of Figure 18, for example, a store clerk who has received an instruction to purchase a product (assorted vegetable A, 150 g) from a customer operates the assorted vegetable A button.

[0101] When there is an operation on the assorted vegetable A button on the registration screen of Figure 18, the registration calculator 10 displays a registration screen as shown in Figure 19. That is, when there is an operation on the assorted vegetable A button on the registration screen of Figure 18, the registration calculator 10 switches from the assorted vegetable tab to the air bag tab as shown in Figure 19. On the registration screen of Figure 19, similar to the small screen SG1 of Figure 6, there are air bag selection buttons (small white square button, medium white square button, large white square button) for selecting each of the recommended air bags (small white square, medium white square, large white square) of assorted vegetable A, and other selection buttons, which are displayed.

[0102] For example, when the store clerk places (or has placed) assorted vegetable A (150 g) in the medium white square, which is one of the recommended air bags (small white square, medium white square, large white square) of assorted vegetable A, the store clerk operates the medium white square button on the registration screen of Figure 19.

[0103] When there is an operation on the medium white square button on the registration screen of Figure 19, the registration calculator 10 displays a registration screen as shown in Figure 20.

[0104] Subsequently, the store clerk places assorted vegetable A in the medium white square selected on the registration screen of Figure 19 (filling it to 150 g by eye measurement) and places it on the weighing platform 106a. Note that the store clerk may operate the medium white square button on the registration screen of Figure 19 after placing assorted vegetable A in the medium white square (filling it to 150 g by eye measurement) and then place it on the weighing platform 106a.

[0105] After placing the prepared food A contained in the white square on the weighing platform 106a, the display of the registration and settlement device 10 is the same as the displays in FIGS. 8 to 11, so the description is omitted.

[0106] In addition, when there is an operation of the cancel button on the registration screen in FIG. 19, the registration device 10 displays the registration screen in FIG. 18 (initial screen). Also, when there is an operation of the cancel button on the registration screen in FIG. 20, the registration device 10 may display the registration screen in FIG. 18 (initial screen) or may display the registration screen in FIG. 19.

[0107] FIGS. 21 and 22 (transition: FIG. 18 → FIG. 19 → FIG. 21 → FIG. 22) show display examples (display examples up to the middle) when, for the prepared food A of a product for which the value of the other tare selection category is "0 (permitted)", that is, a product for which selection of a tare other than the recommended tare by the tare selection button is permitted, a tare other than the recommended tare is selected by the tare selection button (when specifying the tare weight of a tare other than the recommended tare by the tare selection button).

[0108] On the registration screen in FIG. 19, for example, when the store clerk places (or has placed) the prepared food A (150 g) in a tare other than the recommended tares (small white square, medium white square, large white square) of the prepared food A, the clerk operates the other selection button.

[0109] When there is an operation of the other selection button on the registration screen in FIG. 19, the registration and settlement device 10 displays a registration screen as shown in FIG. 21. On the registration screen in FIG. 21, there are tare selection buttons (small white square button, medium white square button, large white square button) for selecting each of the recommended tares (small white square, medium white square, large white square) of the prepared food A, and tare selection buttons (small white round button, medium white round button, large white round button, small transparent square button, etc.) for selecting each of the tares other than the recommended tares (small white round, medium white round, large white round, small transparent square, etc.) of the prepared food A.

[0110] When there is an operation of the medium white round button on the registration screen in FIG. 21, the registration and settlement device 10 displays a registration screen as shown in FIG. 22.

[0111] Subsequently, the store clerk places the prepared food A in the white circle selected on the registration screen of Fig. 22 (containing 150 g by visual measurement) and places it on the weighing platform 106a. Note that the store clerk may operate the button in the white circle on the registration screen of Fig. 22 after placing the prepared food A in the white circle (after containing 150 g by visual measurement) and then place it on the weighing platform 106a.

[0112] Since the display of the registration and settlement device 10 after placing the prepared food A contained in the white circle on the weighing platform 106a is the same as the displays in Figs. 8 to 11, the description thereof is omitted.

[0113] Note that when there is an operation of the cancel button on the registration screen of Fig. 21, the registration and settlement device 10 may display the registration screen of Fig. 18 (initial screen) or the registration screen of Fig. 19. Also, when there is an operation of the cancel button on the registration screen of Fig. 22, the registration and settlement device 10 may display the registration screen of Fig. 18 (initial screen), or the registration screen of Fig. 19, or the registration screen of Fig. 21.

[0114] Note that it may transition from the registration screen of Fig. 18 to the registration screen of Fig. 21. That is, when there is an operation of the prepared food A button on the registration screen of Fig. 18, the registration and settlement device 10 displays the registration screen of Fig. 19 (registration screen with other selection buttons displayed), and when there is an operation of the other selection button on the registration screen of Fig. 19, the registration and settlement device 10 displays the registration screen of Fig. 21 (that is, the registration screen on which both the windbag selection button for selecting the recommended windbag and the windbag selection button for selecting a windbag other than the recommended windbag are displayed selectably). However, when there is an operation of the prepared food A button on the registration screen of Fig. 18, the registration and settlement device 10 may display the registration screen of Fig. 21.

[0115] On the registration screen of Figure 21 when transitioning from Figure 18 → Figure 19 → Figure 21, it is not necessary to display the recommended serving size of side dish A distinguishable from other serving sizes. On the other hand, on the registration screen of Figure 21 when transitioning from Figure 18 → Figure 21, the recommended serving size of side dish A should be displayed distinguishable from other serving sizes. For example, when transitioning from Figure 18 → Figure 21, on the registration screen of Figure 21, the serving size selection buttons (small white square button, medium white square button, large white square button) for the recommended serving sizes of side dish A (small white square, medium white square, large white square) and the serving size selection buttons (small white circle button, medium white circle button, large white circle button, etc.) for serving sizes other than the recommended serving sizes of side dish A (small white circle, medium white circle, large white circle, etc.) are displayed in different display modes (for example, in different colors (the former being a more prominent color)). Note that the display size and display position of the serving size selection buttons may also be different. That is, on the registration screen of Figure 21, both the serving size selection buttons for selecting the recommended serving size and the serving size selection buttons for selecting serving sizes other than the recommended serving size are displayed. However, when transitioning from Figure 18 → Figure 19 → Figure 21, since the recommended serving size has already been notified on the registration screen of the intermediate Figure 19, it is not necessary to notify the recommended serving size again on the registration screen of Figure 21. But when transitioning from Figure 18 → Figure 21, since the recommended serving size has not been notified midway, the recommended serving size is notified on the registration screen of Figure 21.

[0116] Note that on the registration screen of Figure 21 when transitioning from Figure 18 → Figure 21, if there is an operation on the serving size selection button for selecting a serving size other than the recommended serving size, a small screen with a message such as "This is not the recommended serving size", an OK button, and an NG button is displayed. When there is an operation on the OK button, the small screen is erased and the selection (selection of a serving size other than the recommended serving size) is accepted. When there is an operation on the NG button, the small screen is erased and the operation is not accepted.

[0117] Figures 23 and 24 (transitioning from Figure 18 → Figure 23 → Figure 24) show an example of the display (display example up to the middle) when the recommended serving size is selected by the serving size selection button (when the serving size weight of the recommended serving size is specified by the serving size selection button) for side dish C, which is a product where the value of the other serving size selection category is "1 (prohibited)", that is, a product where the selection of serving sizes other than the recommended serving size by the serving size selection button is prohibited.

[0118] On the registration screen (initial screen) of FIG. 18, for example, a store clerk who has received an instruction from a customer to purchase a product (prepared food C, 100 g) operates the prepared food C button.

[0119] When there is an operation on the prepared food C button on the registration screen of FIG. 5, the registration and settlement device 10 displays a registration screen as shown in FIG. 23. That is, when there is an operation on the prepared food C button on the registration screen of FIG. 18, the registration and settlement device 10 switches from the prepared food tab to the tare tab as shown in FIG. 23. On the registration screen of FIG. 23, similar to the small screen SG3 of FIG. 14, white round small buttons, white round medium buttons, and white round large buttons are displayed. In the scene of FIG. 14, since the tare button on the back cannot be operated by the small screen SG3 on the front, another tare (different method) button is displayed on the small screen SG3 on the front. However, in the scene of FIG. 23, since the tare button can be operated, another tare (different method) button is not displayed.

[0120] For example, when the store clerk puts (or has put) the prepared food C (100 g) into the white round large, which is one of the recommended tares (white round small, white round medium, white round large) for the prepared food C, the store clerk operates the white round large button on the registration screen of FIG. 23.

[0121] When there is an operation on the white round large button on the registration screen of FIG. 23, the registration and settlement device 10 displays a registration screen as shown in FIG. 24.

[0122] Subsequently, the store clerk puts the prepared food C into the white round large selected on the registration screen of FIG. 23 (filling 100 g by visual measurement) and places it on the weighing platform 106a. Note that the store clerk may operate the white round large button on the registration screen of FIG. 23 after putting the prepared food C into the white round large (after filling 100 g by visual measurement) and then place it on the weighing platform 106a.

[0123] Since the display of the registration and settlement device 10 after placing the prepared food C contained in the white round large on the weighing platform 106a is the same as the display in FIGS. 8 to 11, the description is omitted.

[0124] In addition, when an operation is performed on the cancel button on the registration screen in Fig. 23, the registration device 10 displays the registration screen (initial screen) in Fig. 18. Further, when an operation is performed on the cancel button on the registration screen in Fig. 24, the registration device 10 may display the registration screen (initial screen) in Fig. 18, or may display the registration screen in Fig. 23.

[0125] Figs. 25 and 26 (transition from Fig. 18 → Fig. 25 → Fig. 26 (Fig. 20), or transition from Fig. 18 → Fig. 25 → Fig. 21) show other display examples (display examples up to the middle) when selecting the prepared food A, which is a product with the value of the other windage selection category being "0 (permitted)", that is, a product for which selection of a windage other than the recommended windage by the windage selection button is permitted.

[0126] When an operation is performed on the prepared food A button on the registration screen in Fig. 18, the registration device 10 may display the small screen SG1 as shown in Fig. 25 instead of the registration screen in Fig. 19.

[0127] When an operation is performed on, for example, the white square middle button on the small screen SG1 in Fig. 25, the registration device 10 erases the small screen SG1 and displays the registration screen as shown in Fig. 26. When an operation is performed on another selection button on the small screen SG1 in Fig. 25, the registration device 10 erases the small screen SG1 and displays the registration screen before windage selection (the registration screen in Fig. 21) after switching from the prepared food tab to the windage tab. That is, based on the operation of the prepared food A button, the registration device 10 displays the windage selection button (the windage selection button for the recommended windage) on the small screen SG1, and when an operation is performed on another selection button on the small screen SG01, the small screen SG01 is erased to enable the operation of the windage button (while enabling the specification of the windage weight by setting input or windage measurement), and switches to the windage tab as shown in Fig. 21 to display the windage selection button (all windage selection buttons). On the registration screen in Fig. 21 when transitioning from Fig. 25 → Fig. 21, the recommended windage of the prepared food A may be displayed so as to be distinguishable from other windages.

[0128] Note that when there is an operation on the white square middle button on the small screen SG1 in Fig. 25, the registration calculation device 10 may maintain the side dish tab as shown in the registration screen of Fig. 26, or may display a registration screen switched to the windbag tab (for example, the registration screen with the windbag selected in Fig. 20).

[0129] Figs. 27 and 28 (Fig. 18 → Fig. 27 → Fig. 28 (Fig. 24), or transition: Fig. 18 → Fig. 27 → Fig. 23) show other display examples (display examples up to the middle) when a side dish C, which is a product with the value of the other windbag selection category being "1 (prohibited)", that is, a product for which the selection of a windbag other than the recommended windbag by the windbag selection button is prohibited, is selected.

[0130] When there is an operation on the side dish C button on the registration screen of Fig. 18, the registration calculation device 10 may display the small screen SG3 as shown in Fig. 27 instead of the registration screen of Fig. 23.

[0131] When there is an operation on the large white circle button on the small screen SG3 in Fig. 27, for example, the registration calculation device 10 erases the small screen SG3 and displays a registration screen as shown in Fig. 28. When there is an operation on the other windbag (different method) button on the small screen SG3 in Fig. 27, the registration calculation device 10 erases the small screen SG1 and displays a registration screen before windbag selection switched from the side dish tab to the windbag tab (the registration screen of Fig. 23). That is, based on the operation of the side dish C button, the registration calculation device 10 displays a windbag selection button (the windbag selection button for the recommended windbag) on the small screen SG3, and when there is an operation on the other windbag (different method) button on the small screen SG03, it erases the small screen SG03 (while enabling the operation of the windbag button (that is, while enabling the specification of the windbag weight by setting input or windbag measurement), and switches to the windbag tab as shown in Fig. 23 and displays a windbag selection button (the windbag selection button for the recommended windbag).

[0132] Note that when there is an operation on the large white circle button on the small screen SG3 in Fig. 27, for example, the registration calculation device 10 may maintain the side dish tab as shown in the registration screen of Fig. 28, or may display a registration screen switched to the windbag tab (for example, the registration screen with the windbag selected in Fig. 24).

[0133] (Display example when the air bag button is operated) Figures 29 to 31 are display examples when the air bag button is operated after selecting a product. For example, when there is an operation of the air bag button on the registration screen of FIG. 19, the registration settlement device 10 pops up and displays the small screen SG4 as shown in FIG. 29. In the small screen SG4 of FIG. 29, when there is a setting input (10 g) or when the air bag is weighed (the weighed value is 10 g), the registration settlement device 10 erases the small screen SG4 and displays the registration screen of FIG. 20. Note that, in the registration screen of FIG. 20 (the registration screen after the operation of the button in the white square) that transitions from the registration screen of FIG. 19, the button in the white square is displayed distinguishable (as a thick dashed frame), but in the registration screen of FIG. 20 (the registration screen after setting input or weighing) that transitions from the small screen SG4 of FIG. 29, it is not necessary to display the button in the white square distinguishable.

[0134] Also, when there is an operation of the air bag button on the registration screen of FIG. 21, the registration settlement device 10 pops up and displays the small screen SG4 as shown in FIG. 30. In the small screen SG4 of FIG. 30, when there is a setting input (14 g) or when the air bag is weighed (the weighed value is 14 g), the registration settlement device 10 erases the small screen SG4 and displays the registration screen of FIG. 22. Note that, in the registration screen of FIG. 22 (the registration screen after the operation of the button in the white circle) that transitions from the registration screen of FIG. 21, the button in the white circle is displayed distinguishable, but in the registration screen of FIG. 22 (the registration screen after setting input or weighing) that transitions from the small screen SG4 of FIG. 30, it is not necessary to display the button in the white circle distinguishable.

[0135] In addition, when an air bag button is operated on the registration screen of Fig. 23, the registration calculator 10 pops up and displays the small screen SG4 as shown in Fig. 31. When there is a setting input (18 g) or when the air bag is weighed (the weighed value is 18 g) on the small screen SG4 of Fig. 31, the registration calculator 10 erases the small screen SG4 and displays the registration screen of Fig. 24. Note that on the registration screen of Fig. 24 (the registration screen after the operation of the large white button) that transitions from the registration screen of Fig. 23, the large white button is displayed in a distinguishable manner, but on the registration screen of Fig. 24 (the registration screen after setting input or weighing) that transitions from the small screen SG4 of Fig. 31, the large white button does not necessarily need to be displayed in a distinguishable manner.

[0136] Figs. 32 to 34 are display examples when the air bag button is operated before selecting a product. For example, when an air bag button is operated on the registration screen (initial screen) of Fig. 5, the registration calculator 10 pops up and displays the small screen SG4 as shown in Fig. 32. When there is a setting input (10 g) or when the air bag is weighed (the weighed value is 10 g) on the small screen SG4 of Fig. 32, the registration calculator 10 erases the small screen SG4 and displays a registration screen as shown in Fig. 33. When there is an operation on the side dish A button on the registration screen of Fig. 33, the registration calculator 10 displays a registration screen as shown in Fig. 34.

[0137] That is, even when there is an operation on the product selection button, if the air bag weight has already been specified, the registration calculator 10 does not display a small screen (such as small screen SG1, small screen SG2, etc.) on which the air bag selection button is arranged.

[0138] Figs. 32 to 34 are examples of registration screens without an air bag tab, but the same applies to registration screens with an air bag tab. For example, when an air bag button is operated on the registration screen (initial screen) of Fig. 18, the registration calculator 10 pops up and displays the small screen SG4. When there is a setting input or when the air bag is weighed on the small screen SG4, the small screen SG4 is erased. Then, when there is an operation on the product selection button, it does not switch to the air bag tab (or does not display a small screen on which the air bag selection button is arranged).

[0139] That is, when a product is selected while the tare weight is not specified, the registration calculator 10 pops up a small screen or switches to the tare tab to display the tare selection button. However, when a product is selected while the tare weight is specified, the tare selection button is not displayed.

[0140] When a product is selected while the tare weight is specified, the registration calculator 10 may perform processing (operations) according to the combination of the already specified tare weight and the selected product. For example, when the already specified tare weight does not match any of the tare weights of one or more recommended tares of the selected product, the registration calculator 10 displays a message such as "This is not the tare weight of the recommended tare" and an OK button indicating to proceed with the processing as it is, and a re-registration button (operation of the re-registration button → a small screen with the tare selection button (for example, the display of the tare selection button of the recommended tare of the product) may be displayed. As an example, when the already specified tare weight is "14 g" and the selected product is side dish A, since the tare weight "14 g" does not match any of the tare weights (8 g, 10 g, 13 g) of the recommended tares (small white square, medium white square, large white square) of side dish A, the registration calculator 10 displays a small screen with a message such as "This is not the tare weight of the recommended tare", an OK button, and a re-registration button. When there is an operation of the OK button, the registration calculator 10 erases the small screen and maintains the tare weight "14 g" (accepts it as it is). When there is an operation of the re-registration button, instead of the small screen, the registration calculator 10 displays a small screen SG1 with the small white square button, the medium white square button, and the large white square button arranged (or switches to the tare tab and displays the small white square button, the medium white square button, and the large white square button).

[0141] Note that the above is a warning and control based on comparison with the recommended air bag. However, instead of or in addition to the warning and control based on comparison with the recommended air bag, warning and control based on comparison of the air bag weight with a predetermined weight (for example, a weight equal to or exceeding a predetermined minimum weight, or a weight equal to or less than a predetermined maximum weight, or a weight within the range of a predetermined minimum weight and a predetermined maximum weight) may be performed. Note that the comparison with the predetermined weight is applicable not only in a scenario where the air bag weight before selection of a product is specified, but also in a scenario where the air bag weight after selection of a product is specified (however, since the air bag weight within a predetermined range is specified by the air bag selection button, it is not applicable in the case of button selection). The predetermined weight may be shared in all devices that refer to the predetermined weight within the sales system 1, similar to the various types of information shown in FIG. 4, and the device that sets the predetermined weight and the device that stores the predetermined weight are not particularly limited.

[0142] (Display control of air bag selection button based on schedule) The registration and settlement device 10 may control the display of the air bag selection button based on the schedule of a sales plan (special sale). For example, air bags (containers) for campaigns such as Christmas, New Year, and collaboration plans may be registered in the air bag master together with their respective campaign periods, and the air bags for campaigns may be registered as the recommended air bags for the target products of the campaigns. For example, a special air bag (special container) for a Christmas campaign is set in the air bag master, and for the target products of the Christmas campaign, a special air bag is set instead of or in addition to the recommended air bag during normal times (non-campaign times). By doing so, when a target product is selected during the Christmas campaign, the air bag selection button for the special air bag may be displayed instead of or in addition to the air bag selection button for the recommended air bag during normal times. During the campaign period, the types of air bags used may increase, or air bags different from usual may be used, which may make it time-consuming to select an air bag. However, if the above measures are taken, an appropriate air bag selection button will be displayed, which is preferable.

[0143] (Control based on remaining quantity) Regarding the display of other selection buttons that are displayed when a product (e.g., prepared food A) for which selection of a tare other than the recommended tare is permitted is selected, it may be controlled based on the remaining number (inventory number) of the tare. For example, the remaining number is managed for each tare (increasing the remaining number at the time of receipt and decreasing it for each consumption), and when the remaining number of the recommended tare is equal to or more than a predetermined number (when there are multiple recommended tares, when the remaining numbers of all the recommended tares are equal to or more than the predetermined number), the other selection buttons are made non-displayed, and when the remaining number of the recommended tare is less than the predetermined number (when there are multiple recommended tares, when the remaining number of at least one of the recommended tares is less than the predetermined number), the other selection buttons may be displayed. Note that the management of the remaining number is realized as the sales system 1. For example, the current remaining number for each tare is stored in any device of the sales system 1, and at the time of input of the tare, the received quantity is input as a set value in any device of the sales system 1, and the remaining number stored in any device of the sales system 1 is increased by the received quantity, and each time the tare is consumed in the individual registration settlement device 10, the remaining number stored in any device of the sales system 1 may be decreased by 1.

[0144] The remaining number of the tare (which may be in units of 1 or 10) may be notified (the remaining number may be displayed on the tare selection button, or the remaining number may be displayed in association with the tare selection button). Also, regarding the tare for which the remaining number has become less than a certain threshold value, it may be notified that the remaining number has decreased (for example, the tare selection button is displayed in a display mode indicating that the remaining number is small). Selection of a tare for which the remaining number has become zero may be made impossible (operation of the tare selection button for a tare for which the remaining number has become zero may be regarded as an error, or the tare selection button for a tare for which the remaining number has become zero may be made non-displayed).

[0145] Instead of or in addition to counting down the remaining quantity each time it is consumed, an operation indicating that the remaining quantity has reached zero may be accepted. For example, a long press of the tare selection button may be accepted as an operation indicating that the quantity has reached zero. This allows the display of the tare selection button to be controlled according to the actual situation when the count is not zero but the actual quantity is zero. Of course, the above operation in one registration settlement device 10 is reflected in other registration settlement devices 10 as well. That is, if there is an operation indicating that the remaining quantity of a certain tare in a registration settlement device 10 has reached zero, the selection of that tare will be disabled not only in that registration settlement device 10 but also in other registration settlement devices 10.

[0146] Similar to the tare, for products, the remaining quantity (in grams) may be managed and the display of the product selection button may be controlled.

[0147] (Image of the tare) The registration settlement device 10 may display an image (photo, illustration, etc.) of the tare on the tare selection button, or may display an image of the tare in association with the tare selection button. The registration settlement device 10 may display an image of the tare for non-recommended tared and may not display an image of the tare for recommended tared. The registration settlement device 10 may display an image of the tare for recommended tared and may not display an image of the tare for non-recommended tared.

[0148] The registration settlement device 10 may display an image of the tare for tared with a low consumption quantity and may not display an image of the tare for tared with a high consumption quantity. The registration settlement device 10 may determine that the consumption quantity is low when the decrease in the remaining quantity within a predetermined period is less than the threshold value, and may determine that the consumption quantity is high when the decrease in the remaining quantity within a predetermined period is equal to or greater than the threshold value. Also, the registration settlement device 10 may determine that the consumption quantity is low when the incoming quantity within a predetermined period is less than the threshold value, and may determine that the consumption quantity is high when the incoming quantity within a predetermined period is equal to or greater than the threshold value.

[0149] As described above, the sales system 1 according to the embodiment has been explained. According to the sales system 1, the registration of tare weight can be more suitably carried out. For example, in order to receive an operation of selecting a tare bag after specifying a product (FIG. 5 → FIG. 6, FIG. 5 → FIG. 14, FIG. 18 → FIG. 19, FIG. 18 → FIG. 23, FIG. 18 → FIG. 25, FIG. 18 → FIG. 27), while confirming the specified product (for example, while recognizing the product name of the purchased product on the screen), it is possible to let the user select a tare bag suitable for the product. That is, the cases of making mistakes in the operation of registering the tare weight and the cases where it takes more time than necessary for registering the tare weight are reduced. In addition, since the selection of the recommended tare bag for the product is promoted after the selection of the product (FIG. 6, FIG. 14, FIG. 19, FIG. 23, FIG. 25, FIG. 27), it is possible to simply register the tare weight of a suitable tare bag. That is, the cases of making mistakes in the operation of registering the tare weight and the cases where it takes more time than necessary for registering the tare weight are further reduced.

[0150] Furthermore, in addition to the flow of specifying the purchased product → specifying the tare weight → specifying the purchased weight → settlement, the sales system 1 also supports other flows (for example, specifying the tare weight → specifying the purchased product → specifying the purchased weight → settlement). Also, for example, regarding the method of specifying the tare weight, in addition to button selection (tare bag selection button), it also supports setting value input and tare bag weighing. Therefore, it is possible to flexibly operate according to various situations (situations of products, tare bags, customers, store clerks, etc.).

[0151] (Modification examples, etc.) As described above, each embodiment has been explained. However, the configuration of the device, the configuration of the data, the processing flow, the display and output modes, etc. can be appropriately changed as shown in the following (1) to (29) for example. Also, the following (1) to (29) may be appropriately combined with each other.

[0152] (1) In the above embodiment, an example where the maximum number of recommended tare bags set for one product is 3 has been explained. However, the number of recommended tare bags set for one product is not particularly limited. For example, five recommended tare bags may be set for a certain product.

[0153] For a certain product, all tare weights may be set as the recommended tare weight. For a product with all tare weights set as the recommended tare weight, there are no tare weights other than the recommended tare weight. When a product with all tare weights set as the recommended tare weight is selected, it may be switched to the tare weight tab without popping up the small screen SG1 or small screen SG3. For example, if prepared food A is a product with all tare weights set as the recommended tare weight, when there is an operation on the prepared food A button on the registration screen in Fig. 18, the registration screen in Fig. 21 is displayed by the registration and settlement device 10.

[0154] (2) In the above embodiment, although the description is omitted, when there is one recommended tare weight, the recommended tare weight may be automatically selected (the tare weight of the recommended tare weight is automatically registered). If one of the white squares with tare weight ID "F002" is the recommended tare weight of prepared food A, when there is an operation on the prepared food A button on the registration screen (initial screen) in Fig. 5, the registration screen in Fig. 7 may be displayed, and when there is an operation on the prepared food A button on the registration screen (initial screen) in Fig. 18, the registration screen in Fig. 20 may be displayed by the registration and settlement device 10. Also, if one of the large white circles with tare weight ID "F006" is the recommended tare weight of prepared food C, when there is an operation on the prepared food C button on the registration screen (initial screen) in Fig. 5, the registration screen in Fig. 15 may be displayed, and when there is an operation on the prepared food C button on the registration screen (initial screen) in Fig. 18, the registration screen in Fig. 24 may be displayed by the registration and settlement device 10.

[0155] (3) In the above embodiment, an example of displaying the small screen SG1 in which the tare weight selection button for the recommended tare weight and other selection buttons are arranged has been described (Figs. 6 and 25), but on the small screen SG1, other tare weight (different method) buttons may be further arranged. That is, in the flow of specifying the purchased product → specifying the tare weight, similar to the case where a product (for example, prepared food C) in which the selection of tare weights other than the recommended tare weight by the tare weight selection button is prohibited is selected, when a product (for example, prepared food A) in which the selection of tare weights other than the recommended tare weight by the tare weight selection button is permitted is selected, other tare weight (different method) buttons may also be displayed. Other tare weight (different method) buttons may also be arranged on the small screen SG2 (Fig. 12) displayed when the other selection button on the small screen SG1 is operated.

[0156] (4) In the above embodiment, when the other selection button on the small screen SG1 is operated, an example of displaying the small screen SG2 (FIG. 12) which displays the airbag selection buttons for airbags other than the recommended airbag has been described. However, the airbag selection button for the recommended airbag may be further displayed. That is, on the small screen SG2, in addition to the airbag selection button for the recommended airbag displayed on the small screen SG1, the airbag selection buttons for airbags other than the recommended airbag that were not displayed on the small screen SG1 may be displayed.

[0157] (5) In the above embodiment, an example of displaying the small screen SG4 (FIGS. 16, 29 to 32) on which a numeric keypad, an enter button, a weighing button, etc. are arranged has been described. However, when providing an airbag tab on the registration screen, instead of displaying the small screen SG4, as the display of the airbag tab (that is, arranged together with the airbag selection button), a numeric keypad, an enter button, a weighing button, etc. may be displayed.

[0158] (6) In the above embodiment, the operation procedure for specifying the airbag weight by setting input has been described as the operation procedure such as setting input of the airbag weight using the numeric keypad on the small screen SG4 → operation of the enter button on the small screen SG4. However, the operation procedure for specifying the airbag weight by setting input is not limited to this. For example, when the small screen SG4 (FIGS. 16, 29 to 32) is being displayed, the numeric keypad on the operation unit 107 may be operated without operating the numeric keypad on the small screen SG4. For example, the operation procedure such as setting input of the airbag weight using the numeric keypad on the operation unit 107 → operation of the enter button on the small screen SG4 may be used, or the operation procedure such as setting input of the airbag weight using the numeric keypad on the operation unit 107 → operation of the execute button on the operation unit 107 (erasing the small screen SG4) may be used.

[0159] In addition, when inputting the tare weight by using the numeric keypad of the operation unit 107, it is not necessary to arrange the numeric keypad on the small screen SG4. That is, an operation procedure such as inputting the tare weight by using the numeric keypad of the operation unit 107 during the display of the small screen SG4 where the numeric keypad is not arranged → operating the confirmation button on the small screen SG4 may be adopted. Further, when inputting the tare weight by using the numeric keypad of the operation unit 107 and operating the execution key of the operation unit 107, it is not necessary to arrange either the numeric keypad or the confirmation button on the small screen SG4. That is, an operation procedure such as inputting the tare weight by using the numeric keypad of the operation unit 107 during the display of the small screen SG4 where neither the numeric keypad nor the confirmation button is arranged → operating the execution key of the operation unit 107 may be adopted.

[0160] In addition, when inputting the tare weight by using the numeric keypad of the operation unit 107, it is not necessary to display the small screen SG4 when inputting the tare weight.

[0161] (7) In the above embodiment, the operation procedure for specifying the tare weight by tare weighing was described as an operation procedure such as operating the weighing button on the small screen SG4 → placing the empty tare on the weighing platform 106a → operating the tare button at the lower part of the registration screen after the weight stabilizes. However, the operation procedure for specifying the tare weight by tare weighing is not limited to this. For example, when a tare weighing key is arranged on the operation unit 107 and the small screen SG4 (FIGS. 16 and 29 to 32) is being displayed, the tare weighing key of the operation unit 107 may be operated without operating the weighing button on the small screen SG4. For example, a procedure such as operating the tare weighing key of the operation unit 107 → placing the empty tare on the weighing platform 106a → operating the tare button at the lower part after the weight stabilizes (or operating the tare weighing key of the operation unit 107, or operating the execution key of the operation unit 107) may be adopted.

[0162] In addition, when arranging the tare weighing key on the operation unit 107, it is not necessary to arrange the weighing button on the small screen SG4. That is, during the display of the small screen SG4 where the weighing button is not arranged, the following procedure may be adopted: operating the tare weighing key on the operation unit 107 → placing the empty tare on the weighing platform 106a → operating the lower tare button after the weight stabilizes (or operating the tare weighing key on the operation unit 107, or operating the execution key on the operation unit 107).

[0163] Also, when arranging the tare weighing key on the operation unit 107, it is not necessary to display the small screen SG4 when weighing the tare weight.

[0164] (8) In the above embodiment, an example of operating a common button (the other tare (different method) button on the small screen SG3, the tare button at the lower part of the registration screen) is described both when specifying the tare weight by setting input and when specifying the tare weight by tare weighing. However, different buttons may be operated when specifying the tare weight by setting input and when specifying the tare weight by tare weighing. That is, the registration and settlement device 10 may separately display, on the small screen SG3 or at the lower part of the registration screen, a button (tare setting button) to be operated when specifying the tare weight by setting input and a button (tare weighing button) to be operated when specifying the tare weight by tare weighing.

[0165] When there is an operation of the tare setting button, the registration and settlement device 10 displays a small screen specialized for specifying the tare weight by setting input (for example, a small screen obtained by deleting the weighing button from the small screen SG4). On the other hand, when there is an operation of the tare weighing button, the registration and settlement device 10 does not display the small screen. When there is an operation of the tare weighing button, the registration and settlement device 10 may prompt the store clerk to place the empty tare on the weighing platform 106a without displaying the small screen.

[0166] (9) In the above embodiment, an example of displaying the tare button at the lower part of the registration screen is described. However, when providing a tare tab on the registration screen, the tare button may be displayed on the tare tab (that is, the tare selection button and the tare button may be arranged side by side).

[0167] (10) In the above embodiment, the operation keys provided in the operation unit 107 are exemplified by the tare key and the like. However, when the operation of the tare button is valid on the clerk display unit 103, the operation of the tare key of the operation unit 107 may be made valid. The same applies to other operation keys of the operation unit 107 (for example, the cancel key, the execute key, the subtotal key, the deposit / cash key, etc.).

[0168] (11) In the above embodiment, an example in which the operation unit 107 includes a tare key (an operation key corresponding to the tare button displayed on the clerk display unit 103) that is operated both when specifying the tare weight by setting input and when specifying the tare weight by tare weighing has been described. However, a separate tare setting key (an operation key corresponding to the tare setting button displayed on the clerk display unit 103) that is operated when specifying the tare weight by setting input and a tare weighing key (an operation key corresponding to the tare weighing button displayed on the clerk display unit 103) that is operated when specifying the tare weight by tare weighing may be provided.

[0169] When there is an operation of the tare setting key of the operation unit 107, the registration and settlement device 10 displays a small screen specialized for specifying the tare weight by setting input, similar to when there is an operation of the tare setting button displayed on the clerk display unit 103. When there is an operation of the tare weighing key of the operation unit 107, the registration and settlement device 10 does not display a small screen, similar to when there is an operation of the tare weighing button displayed on the clerk display unit 103. When there is an operation of the tare weighing key of the operation unit 107, the registration and settlement device 10 may prompt the clerk to place an empty tare on the weighing platform 106a without displaying a small screen.

[0170] (12) In the above, an example in which an empty air bag is placed on the weighing platform 106a after a predetermined operation (declaration) has been described. For example, an example in which the small screen SG4 is displayed after the operation of the air bag button (or air bag key), and an empty air bag is placed on the weighing platform 106a after the operation of the weighing button on the small screen SG4, or an example in which an empty air bag is placed on the weighing platform 106a after the operation of the air bag weighing button (or air bag weighing key) have been described. Instead of this, an empty air bag may be placed on the weighing platform 106a without any operation (declaration). That is, in specifying the weight of the air bag by air bag weighing, it is not necessary to perform a predetermined operation before placing the empty air bag on the weighing platform 106a. For example, on the registration screen of FIG. 6 after specifying (selecting) a product (the same applies to the registration screens of FIGS. 12, 14, 19, 21, 23, 25, and 27), an empty air bag may simply be placed on the weighing platform 106a. Also, for example, on the registration screen of FIG. 5 before specifying (selecting) a product (the same applies to the registration screen of FIG. 18), an empty air bag may simply be placed on the weighing platform 106a. When an empty air bag is placed on the weighing platform 106a while the registration settlement device 10 is displaying the small screen SG1, the registration settlement device 10 erases the small screen SG1. The same applies when an empty air bag is placed on the weighing platform 106a while the small screen SG2 or the small screen SG3 is being displayed. Note that a predetermined operation may be performed after weighing the empty air bag.

[0171] (13) In the above, an example in which the numeric keypad (small screen SG4) is displayed on the clerk display unit 103 after the operation of the display button or the operation key has been described. For example, an example in which the numeric keypad is displayed on the clerk display unit 103 after the operation of the air bag button (or air bag placement number button), or an example in which the numeric keypad is displayed on the clerk display unit 103 after the operation of the air bag key (or air bag placement number key) have been described. Instead of this, the numeric keypad may be displayed on the clerk display unit 103 without the operation of the display button or the operation key.

[0172] In addition, as an operation procedure using the numeric keypad of the operation unit 107, although it has been described that an operation procedure such as inputting the tare weight using the numeric keypad of the operation unit 107 → operating the execution key of the operation unit 107 may be used without arranging the numeric keypad or the enter button on the small screen SG4, in the case of such an operation procedure, the small screen SG4 is not displayed. That is, on the registration screen of FIG. 6 after specifying (selecting) the product (the same applies to the registration screens of FIGS. 12, 14, 19, 21, 23, 25, and 27) or on the registration screen of FIG. 5 before specifying (selecting) the product (the same applies to the registration screen of FIG. 18), when there is an operation of the numeric keypad of the operation unit 107, the registration and settlement device 10 does not display the small screen. When there is an operation of the numeric keypad of the operation unit 107 while the registration and settlement device 10 is displaying the small screen SG1, the small screen SG1 is erased. The same applies when there is an operation of the numeric keypad of the operation unit 107 while the small screen SG2 or the small screen SG3 is being displayed.

[0173] (14) In the above embodiment, an example of managing (storing by a master or the like) the other tare selection category (information regarding the availability of selecting a tare other than the recommended tare) has been described, but it is not necessary to manage the other tare selection category. That is, managing the other tare selection category means managing for each product whether it is possible to select a tare other than the recommended tare. In the above embodiment, for each product, whether it is possible to select a tare other than the recommended tare is managed (FIG. 4), but it is not necessary to manage for each product whether it is possible to select a tare other than the recommended tare. Specifically, for all products (common to all products), it may be allowed to select a tare other than the recommended tare, or for all products, the selection of a tare other than the recommended tare may be restricted (prohibited).

[0174] (When allowing the selection of a tare other than the recommended tare for all products) When there is a selection of any one product, the product registration device 10 pops up and displays a small screen on which the tare selection button and other selection buttons of the product are arranged. Note that an other method button may also be displayed on the above small screen. When there is an operation of the other selection button on the above small screen, the product registration device 10 switches to the tare tab and displays the tare selection buttons of all the tares (the recommended tare of the product, the tare other than the recommended tare of the product) on the tare tab.

[0175] Alternatively, when any one product is selected, instead of displaying the small screen, the merchandise registration device 10 may switch to the tare tab and display the tare selection button and other selection buttons for the product on the tare tab. When an operation is performed on the other selection button on the tare tab, the merchandise registration device 10 displays the tare selection buttons for all the tares (the recommended tare for the product and tares other than the recommended tare for the product) on the tare tab.

[0176] (When restricting (prohibiting) the selection of tares other than the recommended tare for all products) When any one product is selected, the merchandise registration device 10 pops up and displays a small screen on which the tare selection button and other method button for the product are arranged. Alternatively, when any one product is selected, instead of the above, the merchandise registration device 10 may switch to the tare tab and display the tare selection button and other method button for the product on the tare tab.

[0177] (15) In the above embodiment, an example in which the classification is one - layer (classification - product configuration) has been described, but it may be two - layer (major classification - minor classification - product configuration), or three - layer (major classification - middle classification - minor classification - product configuration), or four - layer or more.

[0178] (16) In the above embodiment, an example in which each product belongs to a certain classification and a recommended tare is set for each product has been described (Figs. 4(A), 4(D), 4(E)). However, when setting a recommended tare for each product, there may be no classification. That is, the item of the classification ID may not exist in the product master (Figs. 4(A), 4(D)), and the classification master (Fig. 4(B)) may not exist.

[0179] (17) In the above-described embodiment, an example of setting the recommended air bag for each product has been described (FIGS. 4(A), 4(D), and 4(E)). Instead of setting the recommended air bag for each product, the recommended air bag may be set for each classification. For example, instead of the product master in FIG. 4(A) (the product master in FIG. 4(D), the recommended air bag setting file in FIG. 4(E)), the product master in FIG. 4(D) and the recommended air bag setting file in FIG. 4(F) may be stored.

[0180] According to the product master in FIG. 4(D), the recommended air bag setting file in FIG. 4(F), and the air bag master in FIG. 4(C), for example, the recommended air bags for side dishes B (product ID "S002") are the small white square with an air bag weight of 8 g (air bag ID "F001"), the medium white square with an air bag weight of 10 g (air bag ID "F002"), and the large white square with an air bag weight of 13 g (air bag ID "F003").

[0181] Also, the recommended air bag may be set for each classification and each product. For example, instead of the product master in FIG. 4(A), the product master in FIG. 4(D), the recommended air bag setting file in FIG. 4(E), and the recommended air bag setting file in FIG. 4(F) may be stored.

[0182] When setting the recommended tare weight for each category and each product, prioritize the fine-grained product-by-product settings to determine the recommended tare weight. That is, if the recommended tare weight cannot be determined by referring to the product-by-product settings, refer to the category-by-category settings to determine the recommended tare weight. For example, the recommended tare weights for prepared food B (product ID "S002") are two types, the tare bag with tare bag ID "F001" and the tare bag with tare bag ID "F002", according to the recommended tare weight setting file in Figure 4(E) for each product. According to the recommended tare weight setting file in Figure 4(F) for each category, there are three types, the tare bag with tare bag ID "F001", the tare bag with tare bag ID "F002", and the tare bag with tare bag ID "F003". The registration settlement device 10 first refers to the recommended tare weight setting file in Figure 4(E) for each product and identifies the above two types of tare bags as the recommended tare weights. However, based on the operation of the store clerk (for example, the operation of a predetermined button on the small screen or the tare bag tab, the operation of a predetermined key on the operation unit 107), it refers to the recommended tare weight setting file in Figure 4(F) for each category and identifies the above three types of tare bags. As a result, the recommended tare weight expands from two types to three types, and the range of selection as the recommended tare weight widens. In addition, when both of the two types of tare bags (the small white square with tare bag ID "F001" and the medium white square with tare bag ID "F002") based on the recommended tare weight setting file in Figure 4(E) for each product are not available to the store clerk (for example, out of stock, etc.), a predetermined operation may be performed.

[0183] (18) In the above embodiment, the description was omitted, but switching to the tare bag tab on the registration screen (initial screen) where the tare bag tab is provided may be prohibited. That is, it was explained that the order may be specifying the purchased product → specifying the tare weight → specifying the purchased weight → settlement, or the order may be specifying the tare weight → specifying the purchased product → specifying the purchased weight → settlement. However, regarding the order of specifying the tare weight → specifying the purchased product → specifying the purchased weight → settlement (specifying the tare weight before specifying the product), although specifying the tare weight by entering the number of packages or specifying the tare weight by weighing the tare bag is permitted, specifying the tare weight by button selection (tare bag selection button) may be prohibited.

[0184] Alternatively, switching to the tare bag tab on the registration screen (initial screen) where the tare bag tab is provided may be permitted. Since it is specifying the tare weight before specifying the product, all tare bag selection buttons are displayed on the tare bag tab.

[0185] (19) In the above embodiment, it has been explained that the order may be specifying the purchased product → specifying the tare weight → specifying the purchased weight → settlement, or the order may be specifying the tare weight → specifying the purchased product → specifying the purchased weight → settlement. However, for the latter order (the order of specifying the tare weight → specifying the purchased product →...), it may be possible to set permission or non - permission. When specifying the tare weight before specifying the product is prohibited, the operation of the tare button on the registration screen (initial screen) of FIG. 5 where the tare tab is not provided or the registration screen (initial screen) of FIG. 18 where the tare tab is provided is disabled, and further, switching to the tare tab is prohibited on the registration screen (initial screen) of FIG. 18. Note that the above permission / non - permission setting, similar to the various types of information shown in FIG. 4, may be shared among all devices that refer to such settings within the sales system 1, and the device for setting such permission / non - permission and the device for storing the content of such permission / non - permission setting are not particularly limited.

[0186] (20) In the above embodiment, it has been explained that the order may be specifying the purchased product → specifying the tare weight → specifying the purchased weight → settlement, or the order may be specifying the tare weight → specifying the purchased product → specifying the purchased weight → settlement. However, in the case of the latter order (the order of specifying the tare weight → specifying the purchased product →...), product narrowing - down may be performed based on the specified tare.

[0187] For example, if switching to the tare tab on the registration screen (initial screen) where the tare tab is provided is permitted, and when there is an operation of a single tare selection button from the tare tab on the registration screen (initial screen) (that is, when a single tare is selected), the registration and settlement device 10 displays the product selection buttons of the products for which the selected tare is a recommended tare (that is, products for which the tare is one of the recommended tares).

[0188] For example, when a single tare is selected, the registration and settlement device 10 may display a small screen on which the product selection buttons of the products for which the tare is a recommended tare are arranged.

[0189] For example, when a product that recommends a selected airbag is a product under a certain product tab (for example, the side dish tab) (that is, when it is not distributed among products under two or more product tabs), when one airbag is selected, the registration settlement device 10 may automatically switch to the product tab that displays the product selection button of the product that recommends the airbag (after automatically switching, the product selection button of the product that recommends the airbag may be highlighted, or only the product selection button of the product that recommends the airbag may be displayed after automatically switching).

[0190] For example, when one airbag is selected, the registration settlement device 10 may automatically switch to a special tab (a tab for selecting filtered products) different from the original product tab, and display the product selection button of the product that recommends the airbag in the special tab.

[0191] Note that product filtering may be similarly performed even when a recommended airbag is set for classification. Also, when a recommended airbag is set for both classification and products, products with a finer granularity may be prioritized and product filtering may be performed. For example, it is effective when adopting a specific airbag corresponding to a specific product (for example, a dedicated airbag for products for Christmas or New Year, a limited airbag for limited products of a collaboration project such as anime) or a specific classification (for example, a classification for products for Christmas or New Year, a classification for limited products of a collaboration project).

[0192] (21) In the above embodiment, it was explained that the recommended airbag for each product is set in advance, but a recommended airbag may be set during the sale of the product (when specifying the product). For example, when there is an operation of the airbag selection button of an airbag other than the recommended airbag as the airbag of a certain product (for example, product a) (when the selection of an airbag other than the recommended airbag is selected), the registration settlement device 10 confirms with the store clerk whether to register (set) the selected airbag other than the recommended airbag as the recommended airbag of product a, and if there is an affirmative operation by the store clerk, the airbag may be set as the recommended airbag of product a in the product master (or the recommended airbag setting file).

[0193] For example, after selecting product a, if a windbag other than the recommended windbag of product a is selected on the small screen or the expense tab, the registration calculation device 10 displays a small screen (recommended windbag registration necessity confirmation screen) that arranges a message "Do you want to register it in the recommended windbag of product a?", a "Yes" (register) button, and a "No" (do not register) button (displayed instead of the previous small screen or in front of the expense tab). When there is an operation of the "Yes" button, the selected windbag may be set as the recommended windbag of product a in the product master (or recommended windbag setting file).

[0194] Note that the timing of confirmation with the store clerk or receiving an operation from the store clerk (the timing of displaying the recommended windbag registration necessity confirmation screen) does not have to be the timing when a windbag other than the recommended windbag is selected. For example, it may be after the operation of the subtotal button, after the operation of the registration completion button in (22) below, or after the end of the transaction (after settlement). Regarding the timing of setting in the product master (or recommended windbag setting file) as the recommended windbag, it does not have to be immediately after the positive operation of the store clerk (as long as it is reflected by the next day).

[0195] That is, it has been explained that it is sufficient if any device in the sales system 1 has a function of presetting the recommended windbag for each product (recommended windbag presetting function) (that is, the registration calculation device 10 may have the recommended windbag presetting function). As described above, the registration calculation device 10 may have a function of setting the recommended windbag for each product at the time of sale (recommended windbag setting function at the time of sale) instead of or in addition to the recommended windbag presetting function.

[0196] In addition to the scenario of adding a recommended product to an existing product, in the scenario where the recommended windbag is not set for a new product, it is effective because the recommended windbag can be set at the scene (sales scene). Moreover, it is even more effective if it is reflected immediately instead of by the next day.

[0197] In the above-described embodiment, an example in which the registration settlement device 10 registers and settles one product has been described (for example, FIGS. 8 to 11). However, the registration settlement device 10 may register a plurality of products and settle them together. That is, in the above-described embodiment, an example in which after the selling price of one product is determined, the settlement (settlement of the one product) is advanced based on the operation of the subtotal button has been described. However, after the selling price of one product is determined, the next product (second item, third item, etc.) can be registered, and the settlement (settlement of the plurality of products registered so far) may be advanced based on the subsequent operation of the subtotal button.

[0198] For example, a registration completion button that is operable after the selling price is determined and is operated before the operation of the subtotal button may be arranged on the registration screen (for example, arranged on the left side of the subtotal button). If it is before the operation of the subtotal button, the next product may be registered by operating the registration completion button.

[0199] (Flow when registering and settling one product) Select the first item product (or register the tare weight before product selection) →,..., → Determine the selling price of the first item product → The registration completion button becomes operable (the subtotal button remains inoperable) → Operate the registration completion button → The subtotal button becomes operable and the registration completion button becomes inoperable) → Operate the subtotal button → Display the settlement screen (subtotal screen) → (The following is omitted)

[0200] (Flow when registering and settling two products) Select the first item product (or register the tare weight before product selection) →,..., → Determine the selling price of the first item product → The registration completion button becomes operable (the subtotal button remains inoperable) → Operate the registration completion button → The subtotal button becomes operable and the registration completion button becomes inoperable) → Select the second item product (or register the tare weight before product selection) →,..., → Determine the selling price of the second item product → The registration completion button becomes operable (the subtotal button is operable) → Operate the registration completion button → The subtotal button becomes operable and the registration completion button becomes inoperable) → Operate the subtotal button → Display the settlement screen (subtotal screen) → (The following is omitted)

[0201] (Procedure when registering three items and settling the bill (after determining the selling price of the second item)) Determination of the selling price of the second item → The registration completion button becomes operable (the subtotal button remains operable) → Operation of the registration completion button → The subtotal button becomes operable and the registration completion button becomes inoperable) → Selection of the third item (or registration of the tare weight before item selection) →,..., → Determination of the selling price of the third item → The registration completion button becomes operable (the subtotal button remains operable) → Operation of the registration completion button → The subtotal button becomes operable and the registration completion button becomes inoperable) → Operation of the subtotal button → Display of the settlement screen (subtotal screen) → (The following is omitted) The procedure for registering four items and settling the bill is the same.

[0202] As described above, when registering items from the second item onwards, the subtotal button can be operated. However, if the subtotal button is operated while registering items from the second item onwards, the registration of the item being registered (the item for which the operation of the registration completion button has not been completed) may be aborted (stopped), and the process may proceed to the settlement screen (subtotal screen) for settling one or more other items (items for which the operation of the registration completion button has been completed).

[0203] (23) In the above embodiment, an example of returning to the registration screen before identifying the item or tare weight by operating the cancel button (or the cancel key of the operation unit 107), that is, an example in which it is possible to re-identify the item, etc. by operating the cancel button, etc. has been described. However, it may be possible to simply re-identify the item, etc. again (without operating the cancel button, etc.).

[0204] For example, in the case of a mode without the registration completion button in the above (22), a store clerk who has confirmed the selling price of the product operates the subtotal button to proceed with the settlement. However, before operating the subtotal button, it is also possible to re-identify the product by operating the product selection button or the like, or to re-identify the tare weight by operating the tare selection button or the like, and it may be possible to change (overwrite and update) the identified product and tare weight. That is, even if there is a mistake in pressing the button, if it is before operating the subtotal button, simply press the correct button again (if necessary, switch tabs and press the correct button again), and the identified content may be updated. The same applies to specifying the purchase weight (placing the product contained in the tare on the weighing platform 106a). When the product, tare weight, etc. are changed, the registration settlement device 10 recalculates the selling price. The cancel button (or the cancel key on the operation unit 107) may be used as a button (key) to operate when canceling the transaction after operating the subtotal key (after starting the settlement and before completing the settlement).

[0205] Also, for example, in the case of a mode with the registration completion button in the above (22), a store clerk who has confirmed the selling price of the product operates the registration completion button. However, before operating the registration completion button, similar to before operating the subtotal button in the mode without the registration completion button, it may be possible to re-identify the product, re-identify the tare weight, and re-identify the purchase weight. When the product, tare weight, etc. are changed, the registration settlement device 10 recalculates the selling price. The cancel button (or the cancel key on the operation unit 107) may be used as a button to operate when canceling the product after operating the completion button on the registration screen, or as a button to operate when canceling individual products on the settlement screen, or as a button (key) to operate when canceling the entire transaction on the settlement screen.

[0206] (24) In the above-described embodiment, an example of specifying a product by operating a product selection button has been described. However, the product specifying method is not limited to this. For example, it may be a product specifying method by inputting a PLU item number, barcode scanning, or sensing by a sensor provided for each product (for example, sensing a change according to the operation of taking out the product (such as the inclination of the display container), or sensing an explicit operation by a store clerk when taking out the product (touching an electronic shelf label with a sensor)).

[0207] Note that, similar to the case where a product is specified by operating a product selection button, even when a product is specified by a method other than operating a product selection button (PLU item number input, barcode scanning, sensing), a product selection button may be displayed on the cost calculation selection screen (small screens SG1 to SG3) or the cost calculation tab.

[0208] (25) In the above-described embodiment, an example in which the registration and settlement device 10 includes a drawer 109 has been described (FIG. 3). However, the registration and settlement device 10 may include an automatic change dispenser instead of the drawer 109.

[0209] (26) In the above-described embodiment, an example in which the registration and settlement device 10 settles in cash has been described. However, the registration and settlement device 10 may settle in non-cash (for example, credit card, electronic money) instead of or in addition to cash.

[0210] (27) In the above-described embodiment, an example in which the registration and settlement device 10 has a product registration function and a settlement function has been described. However, the registration and settlement device 10 may not have a settlement function. Hereinafter, when the registration and settlement device 10 does not have a settlement function, to avoid a contradiction in names, the registration and settlement device 10 without a settlement function is referred to as a registration device 20.

[0211] The registration device 20 may have, for example, a configuration that does not include the drawer 109 among the configurations of the registration and settlement device 10 shown in FIG. 3. The registration device 20 may issue a label that can be read by another device, or may transmit settlement information to another device.

[0212] (28) In the above-described embodiment, an example in which the registration settlement device 10 includes the measurement unit 106 has been described. However, the registration settlement device 10 may not have the measurement unit 106. Hereinafter, the registration settlement device 10 that does not have the measurement unit 106 is referred to as a registration settlement device 30. Further, the registration settlement device 10 that does not have either the measurement unit 106 or the settlement function is referred to as a registration device 40. The registration settlement device 30 (similarly for the registration device 40) may be a device that reads a barcode attached to a product and identifies the product.

[0213] (29) In the above-described embodiment, part or all of each function (input / output, storage, processing (including determination)) in the registration settlement device 10 may be realized in another device different from the device described as the execution entity of the function. That is, the registration settlement device 10 may be configured by two or more devices (apparatuses).

[0214] For example, the registration settlement device 10 may not store information (for example, part or all of the information shown in FIG. 4) in its own storage unit 102. That is, the registration settlement device 10 may refer to information stored in other devices (other registration settlement devices 10 (representative registration settlement device 10), store controller, management device, external server). The same applies to the registration device 20, the registration settlement device 30, and the registration device 40.

[0215] Further, instead of the registration settlement device 10, another device (for example, a cloud server) may calculate the selling price from the unit price and the purchase weight. The registration settlement device 10 may function as a so-called thin client specialized for input / output interfaces and the like. For example, a cloud server may execute a program for controlling the operation of the registration settlement device 10, and the registration settlement device 10 may display a screen (screens in FIGS. 5 to 34) generated by the cloud server by means of a browsing function. The same applies to the registration device 20, the registration settlement device 30, and the registration device 40.

[0216] <Summary of the Embodiment> [Technical Field] The present invention relates to a registration device and a program. [Background Art] An apparatus for subtracting the tare weight to obtain the net weight is known (see, for example, Patent Document 1). [Prior Art Documents] [Patent Documents] [Patent Document 1] Japanese Patent Application Laid-Open No. 61-259377 [Summary of the Invention] [Problems to be Solved by the Invention] Naturally, if the tare weight of the package is not correctly registered (input) to the apparatus, the net weight cannot be correctly calculated. However, there is room for improvement in registering the tare weight, such as when the registration operation is mistaken or when it takes more time than necessary to avoid mistakes. The present invention has been made in view of such circumstances, and an object thereof is to provide a technique capable of more suitably performing the registration of the tare weight. [Means for Solving the Problems]

[0217] (1) One aspect for solving the above-described problems is a registration apparatus (for example, registration and settlement apparatus 10, registration apparatus 20, registration and settlement apparatus 30, registration apparatus 40) including a product identification means for identifying a product (for example, identifying a product by a product selection button, a PLU product number, barcode scanning, etc.) and a tare selection means for receiving an operation of selecting a tare (for example, selecting a tare by a tare selection button), wherein the tare selection means receives an operation of selecting a tare after the product is identified by the product identification means. According to the registration apparatus of (1), the registration of the tare weight can be more suitably performed. For example, according to the registration apparatus of (1), since an operation of selecting a tare is received after the product is identified (that is, since the tare selection operation is after the product is identified), it is possible to select a tare suitable for the identified product while confirming the identified product. That is, the cases where the operation of registering the tare weight is mistaken or where it takes more time than necessary to register the tare weight are reduced.

[0218] (2) For each product, a recommended tare weight recommended for use with that product is determined (for example, it is set in one of the devices in the sales system 1, and there is a recommended tare weight whose setting content is stored in the product master (FIG. 4(A)) or the recommended tare weight setting file (FIGS. 4(E), 4(F)) in one of the devices in the sales system 1). When the product is identified by the product identification means, the tare weight selection means accepts an operation of selecting the recommended tare weight of the product (for example, as shown in FIGS. 6, 14, 19, 23, 25, 27, by displaying a tare weight selection button for the recommended tare weight of the product, an operation of selecting the recommended tare weight of the product is accepted). It is the registration device according to (1). (2) According to the registration device of (2), the registration of the tare weight can be more suitably performed. For example, according to the registration device of (2), after the selection of the product, the selection of the recommended tare weight of the product is promoted, so that the tare weight of a suitable tare weight can be easily registered.

[0219] (3) For each product, whether or not the selection of a non-recommended tare weight (that is, a tare weight other than the recommended tare weight) that does not correspond to the respective recommended tare weight is permitted is determined (for example, it is set in one of the devices in the sales system 1, and there is an other tare weight selection classification whose setting content is stored in the product master (FIG. 4(A)) or the recommended tare weight setting file (FIGS. 4(E), 4(F)) in one of the devices in the sales system 1). When the product identified by the product identification means is a product for which the selection of the non-recommended tare weight is permitted (for example, prepared food A), in addition to the operation of selecting the recommended tare weight of the product, the tare weight selection means can accept an operation of selecting the non-recommended tare weight of the product (for example, in addition to displaying a tare weight selection button for the recommended tare weight of prepared food A on the small screen SG1 of FIG. 6, a tare weight selection button for a tare weight other than the recommended tare weight of prepared food A is displayed on the small screen SG2 of FIG. 12. Also, in addition to displaying a tare weight selection button for the recommended tare weight of prepared food A on the registration screen of FIG. 19, a tare weight selection button for the recommended tare weight of prepared food A and a tare weight selection button for a tare weight other than the recommended tare weight of prepared food A are displayed on the registration screen of FIG. 22). It is the registration device according to (1) or (2). According to the registration device of (3), the registration of the tare weight can be more suitably performed. For example, according to the registration device of (3), a product that allows the use of a tare other than the recommended tare is defined, and for the corresponding product, the selection of a tare other than the recommended tare is allowed, so that the tare weight of a tare other than the recommended tare can be registered flexibly (for example, even when the recommended tare of the product is out of stock) and simply.

[0220] (4) For each product, it is determined whether the selection of a non-recommended tare that does not correspond to the respective recommended tare is permitted. When the product specified by the product specifying means is a product for which the selection of the non-recommended tare is not permitted (for example, prepared food C), the registration device according to any one of (1) to (3) is characterized in that it accepts an operation of selecting the recommended tare of the product while not accepting an operation of selecting the non-recommended tare of the product (for example, displaying a tare selection button for the recommended tare of prepared food C on the small screen SG3 in FIG. 14, while not displaying a tare selection button for a tare other than the recommended tare of prepared food C on either the small screen or the product tab). (4) According to the registration device of (4), the registration of the tare weight can be more suitably performed. For example, according to the registration device of (4), a product that allows the use of a tare other than the recommended tare is defined, and for products that do not correspond, the selection of a tare other than the recommended tare is not allowed, so that a situation where the tare weight of a tare other than the recommended tare is registered by mistake does not occur.

[0221] (5) A tare selection button display area (for example, the tare tab on the registration screen in FIG. 19, the tare tab on the registration screen in FIG. 23) where tare selection buttons for accepting operations of selecting individual tares are arranged, another display area (for example, the product tab) different from the tare selection button display area, and display means (for example, the clerk display unit 103) that can be switched and displayed are provided. When a product is specified by the product specifying means, the display means switches from the other display area to the tare selection button display area without an operation (for example, FIG. 18 → FIG. 19, FIG. 18 → FIG. 23). The registration device according to any one of (1) to (4) is characterized by this. According to the registration device of (5), the registration of the tare weight can be more suitably carried out. For example, according to the registration device of (5), since the tare selection button is automatically displayed after the product is specified, the tare weight can be registered simply (without the tab switching operation).

[0222] (6) For each product, a recommended tare recommended for use as the tare for each product is determined, and a tare selection button display area provided with a tare selection button for receiving an operation of selecting an individual tare, and another display area different from the tare selection button display area, and display means that can be switched and displayed are provided. The display means can display, in the tare selection button display area, the tare selection button for the recommended tare of the product and the tare selection button for a non-recommended tare not corresponding to the recommended tare of the product (for example, in FIG. 21, the tare selection button for the recommended tare of side dish A and the tare selection button for a tare other than the recommended tare of side dish A can be displayed). When the product is specified by the product specifying means (for example, when the product selection button for side dish A is operated on the registration screen of FIG. 18), a pop-up screen arranged with the tare selection button for the recommended tare of the product and a predetermined button (for example, another selection button) to be operated when selecting the non-recommended tare of the product is displayed (for example, as shown in FIG. 25, a small screen SG1 arranged with the tare selection button for the recommended tare of side dish A and the other selection button is displayed). When the predetermined button is operated on the pop-up screen (for example, when the other selection button on the small screen SG1 in FIG. 25 is operated), without an operation, it switches from the other display area to the tare selection button display area (for example, the registration screen of FIG. 21 is displayed), which is the registration device according to any one of (1) to (5). According to the registration device of (6), the registration of the tare weight can be more suitably performed. For example, according to the registration device of (6), after the product is specified, a small screen suitable for displaying the tare selection button of the recommended tare is displayed. When selecting a tare other than the recommended tare, if the other selection button is operated on the small screen, it switches to the tab displaying the tare selection buttons of all tares (that is, since the range of selectable tares is changed and the tare selection buttons are displayed in two steps), the operability regarding the registration of the tare weight in a normal scene (for example, a scene where the recommended tare of the product is not out of stock) is improved, and the operability can also be ensured in a special scene (for example, a scene where the recommended tare of the product is out of stock).

[0223] (7) For each product, a recommended tare recommended to be used as the tare for each product is determined. When the product is specified by the product specifying means, the display means displays, in the tare selection button display area, the tare selection button of the recommended tare of the product and the tare selection button of a non-recommended tare that does not correspond to the recommended tare of the product in different display modes (for example, on the registration screen of FIG. 21, the tare selection button of the recommended tare of prepared food A and the tare selection button of a tare other than the recommended tare of prepared food A are displayed in different display modes). It is the registration device according to any one of (1) to (6). (7) According to the registration device of (7), the registration of the tare weight can be more suitably performed. For example, according to the registration device of (7), since the recommended tare of the specified product can be seen at a glance, the operability regarding the registration of the tare weight is improved.

[0224] (8) One aspect for solving the above-described problems is a registration device including product selection means for receiving an operation of selecting a product (for example, selecting by a product selection button) and tare selection means for receiving an operation of selecting a tare (for example, selecting a tare by a tare selection button), wherein the product selection means receives an operation of selecting a product after the tare is selected by the tare selection means. According to the registration device of (8), it is possible to suitably carry out sales by weighing. For example, according to the registration device of (8), while checking the selected tare weight, the user can be made to select a product. Also, the products can be narrowed down and selected according to the tare weight.

[0225] (9) One aspect for solving the above-described problems is a program for causing a registration device for registering products to function as a computer, the program causing the computer to function as product specifying means for specifying a product and tare weight selecting means for receiving an operation of selecting a tare weight, and the tare weight selecting means receiving an operation of selecting a tare weight after the product has been specified by the product specifying means. According to the program of (9), similar to the registration device of (1), it is possible to more suitably carry out the registration of the tare weight.

[0226] Note that, a program for realizing the functions of each of the devices described above (for example, the registration settlement device 10, the registration device 20, the registration settlement device 30, the registration device 40, etc.) may be recorded on a computer-readable recording medium, and the program recorded on this recording medium may be read into a computer system and executed to perform the processing of each of the above devices. Here, "reading and executing the program recorded on the recording medium by the computer system" includes installing the program in the computer system. The "computer system" as used herein is assumed to include hardware such as an OS and peripheral devices. Further, the "computer system" may include a plurality of computer devices connected via a network including a communication line such as the Internet, WAN, LAN, or dedicated line. Also, the "computer-readable recording medium" refers to a portable medium such as a flexible disk, magneto-optical disk, ROM, CD-ROM, etc., and a storage device such as a hard disk built into the computer system. Thus, the recording medium storing the program may be a non-transitory recording medium such as a CD-ROM. Also, the recording medium includes an internal or external recording medium provided so as to be accessible from a distribution server for distributing the program. The code of the program stored in the recording medium of the distribution server may be different from the code of the program in a form executable by the terminal device. That is, as long as it can be downloaded from the distribution server and installed in a form executable by the terminal device, the form stored in the distribution server does not matter. Note that the program may be divided into a plurality of parts, downloaded at different timings, and then combined by the terminal device, or the distribution servers for distributing each of the divided programs may be different. Furthermore, the "computer-readable recording medium" also includes a volatile memory (RAM) inside a computer system that becomes a server or a client when a program is transmitted via a network, which holds the program for a certain period of time. Also, the above program may be for realizing a part of the functions described above.Furthermore, it may be a so-called difference file (difference program) that can be realized in combination with a program already recorded in a computer system to achieve the above-described functions.
