[0008] Fig. 1 is a diagram showing a store in which the sales system 1 is installed. The store in which the sales system 1 in this embodiment is installed is, for example, a store that sells food products in a commercial facility (for example, a department store, a shopping center, inside a train station, a shopping street, etc.) as shown in Fig. 1.

[0009] As shown in FIG. 1, various foods are displayed as merchandise in a display case. A plurality of registered settlement devices 10 (registered settlement device 10-1, registered settlement device 10-2, ...) are installed on the display case. The registered settlement device 10 is equipped with a weighing platform 106a on which merchandise to be weighed is placed. Inside the display case are store clerks (employees), and outside are customers. In FIG. 1, there is one store clerk (symbol S) and two customers (symbol C), but the numbers are merely examples. The registered settlement device 10 may also be called a weighing price device, a sales data processing device, etc.

[0010] (Basic flow of product sales) The basic flow (process) of selling products is explained below. Among the following processes 1 to 6, processes 2 to 5 correspond to the registration of purchased products (products instructed to be purchased by a customer), and process 6 corresponds to payment.

[0011] (Step 1) Accepting product purchase instructions from customers A customer instructs a store clerk to purchase a product. Specifically, the customer instructs the store clerk on the product to be purchased and the purchase weight (or the desired purchase amount). In other words, the store clerk accepts the product purchase instruction from the customer.

[0012] (Step 2) Identifying (designating) the product to be purchased A store clerk (who has received an instruction from the customer to purchase a product) identifies the purchased product on the registered settlement device 10. For example, the registered settlement device 10 displays multiple product buttons (multiple product buttons each assigned a product code) corresponding to each product, and the store clerk operates the product button of the product purchased by the customer from among the multiple product buttons. Based on the operation of the product button, the registered settlement device 10 identifies and displays (to the store clerk and customer) the product name and unit price of the purchased product (for example, unit price per 100g).

[0013] (Step 3) Setting the tare weight The store clerk sets the weight to be tared (tare weight) in the registered settlement device 10. For example, the store clerk weighs the weight of a container (empty container) that will contain the purchased items using the registered settlement device 10. The registered settlement device 10 may also display multiple container buttons corresponding to one or more predetermined containers (whose weights are known), and the store clerk may operate the container button of the container that will contain the purchased items from among the multiple container buttons. The registered settlement device 10 may display the container weight (to the store clerk or customer) after the weight has stabilized (or when the container weight has been determined based on the operation of the container button).

[0014] (Step 4) Weighing the purchased items The store clerk places the purchased items in a container and weighs them on the registration settlement device 10. After the weight has stabilized, the registration settlement device 10 displays (to the store clerk and customer) the weight of the purchased item (purchase weight; net weight) and the selling price of the purchased item. The registration settlement device 10 calculates the selling price of the purchased item from the unit price of the purchased item and the weight of the purchased item. If a discount or allowance has been applied to the purchased item, the registration settlement device 10 calculates the selling price of the purchased item using the discounted unit price / discounted unit price as the unit price of the purchased item.

[0015] (Step 5) Enter the store clerk code (employee code) The clerk inputs a clerk code (an example of information that can identify each clerk) into the registered settlement device 10. For example, the registered settlement device 10 displays multiple clerk buttons (multiple clerk buttons to which a clerk code is respectively assigned) corresponding to each clerk, and the clerk operates his / her own clerk button from among the multiple clerk buttons. The registered settlement device 10 associates and stores the sales price determination data including the sales price of the purchased item and the clerk code of the clerk. Specifically, the registered settlement device 10 generates and stores pre-subtotal information (FIG. 4(A)) including the clerk code of the clerk, the sales price determination data, and the like.

[0016] Registration of one purchased item for one customer is completed by carrying out steps 2 to 5. Therefore, if a customer purchases multiple items, steps 2 to 5 are repeated.

[0017] For example, if a customer (say customer A) instructs a store clerk to purchase product A and product B (step 1), the store clerk in charge of customer A (the clerk who accepts the instructions from customer A) performs steps 2 to 5 for product A and steps 2 to 5 for product B.

[0018] The registration and settlement device 10 generates and stores pre-subtotal information for product A (FIG. 4(A)) when a clerk code for product A is input (step 5). The registration and settlement device 10 generates and stores pre-subtotal information for product B (FIG. 4(A)) when a clerk code for product B is input (step 5). In other words, the registration and settlement device 10 generates and stores pre-subtotal information for each purchased product.

[0019] Customer A may instruct the clerk to purchase product A as the first item (step 1), and after the clerk enters the clerk code for product A (step 5), instruct the clerk to purchase product B as the second item. Customer A may also instruct the clerk to purchase product A as the first item (step 1), and instruct the clerk to purchase product B as the second item before the clerk enters the clerk code for product A (step 5). In other words, the customer may instruct the clerk to purchase the second and subsequent items at any time before step 6 (checkout) described below.

[0020] (Step 6) Settlement When the clerk has completed the registration of all the purchased items of the customer, the clerk performs an operation to proceed to settlement (an operation to finish registration) on the registration-settlement device 10. Specifically, the clerk performs an operation to proceed to settlement while inputting a clerk code (the clerk code of the clerk in charge) into the registration-settlement device 10. For example, the registration-settlement device 10 may display a subtotal button (details will be described later) that also serves as a clerk code specification, and the clerk may operate the subtotal button. Based on the operation of the subtotal button, the registration-settlement device 10 displays a settlement screen for settlement, and executes settlement processing based on the clerk's operation (for example, operation of the deposit / current button, input of the deposit amount, etc.), and completes the transaction.

[0021] The reason why the clerk code is input to the registered settlement device 10 in step 6 will be explained. When the registered settlement device 10 executes settlement processing for a certain customer, it executes settlement processing for the customer based on one or more pieces of pre-subtotal information for the customer (pre-subtotal information in a number corresponding to the number of products purchased by the customer) (for example, it generates post-subtotal information for the customer from one or more pieces of pre-subtotal information for the customer (FIG. 4(B))). However, in addition to one or more pieces of pre-subtotal information for the customer, pre-subtotal information for other customers may also be generated and stored. In other words, when executing settlement processing for a certain customer, it is necessary to extract one or more pieces of pre-subtotal information for the customer. Therefore, when starting settlement for a customer whom the clerk has served, the clerk enters his / her own clerk code into the registered settlement device 10 (operates a subtotal button that also serves to specify his / her own clerk code) in order to extract one or more pieces of pre-subtotal information for the customer whom he / she has served. Furthermore, even if there is a mixture of pre-subtotal information for customers for whom you are the sales clerk and pre-subtotal information for customers for whom another sales clerk is the sales clerk, the pre-subtotal information includes the sales clerk code of the sales clerk, so by entering your own sales clerk code, you can extract (identify) the pre-subtotal information for customers for whom you are the sales clerk.

[0022] (Interrupting the processing of other customers (staff members)) The registration and settlement device 10 links each product to a clerk code after the selling price of each product is determined (calculated) (step 5). That is, the data of each product (sales price determination data) is linked to the clerk (clerk code) by an explicit operation of the clerk. In other words, the registration and settlement device 10 does not automatically link the logged-in clerk (clerk code) to the data of all products generated during login by the clerk, but determines the clerk (clerk code) to be linked to the data of each product by operation. Therefore, the processing can be easily divided for each registration of one product (steps 2 to 5). In relation to the above, the registration and settlement device 10 can process transactions of other customers (other clerks) while processing a transaction of one customer (one clerk in charge) (registration in steps 2 to 5, settlement in step 6).

[0023] (Interrupt processing example 1) For example, the registration and settlement device 10 can execute the registration process of one item of another customer b (the sales clerk "Takada" in charge) between the registration process of the first item of a product of customer a (the sales clerk "Kobayashi" in charge) and the registration process of the second item of a product. The registration and settlement device 10 executes the registration process (steps 2 to 5) of the first item of a product of customer a by the operation of the sales clerk "Kobayashi" in charge. Then, the registration and settlement device 10 executes the registration process (steps 2 to 5) of the first item of a product of customer b by the operation of the sales clerk "Takada" in charge. Then, the registration and settlement device 10 executes the registration process (steps 2 to 5) of the second item of a product of customer a by the operation of the sales clerk "Kobayashi" in charge. Then, the registration and settlement device 10 executes the settlement process (step 6) of customer a by the operation of the sales clerk "Kobayashi" in charge. Then, the registration and settlement device 10 executes the settlement process (step 6) of customer b by the operation of the sales clerk "Takada" in charge. In other words, the registration and settlement device 10 executes the process in the following order: registration of one item for customer a by the sales clerk "Kobayashi" → registration of one item for customer b by the sales clerk "Takada" → registration of two items for customer a by the sales clerk "Kobayashi" → settlement of all two items for customer a by the sales clerk "Kobayashi" → settlement of all one item for customer b by the sales clerk "Takada".

[0024] (Interrupt processing example 2) For example, the registration and settlement device 10 can execute the registration and settlement process of one item of another customer b (clerk in charge "Takada") between the registration process of the first item of a product and the registration process of the second item of a customer a (clerk in charge "Kobayashi"). Specifically, the registration and settlement device 10 executes the registration process (steps 2 to 5) of the first item of a product of customer a by the operation of the clerk in charge "Kobayashi". Then, the registration and settlement device 10 executes the registration process (steps 2 to 5) of the first item of a product of customer b by the operation of the clerk in charge "Takada". Then, the registration and settlement device 10 executes the settlement process (step 6) of customer b by the operation of the clerk in charge "Takada". Then, the registration and settlement device 10 executes the registration process (steps 2 to 5) of the second item of a product of customer a by the operation of the clerk in charge "Kobayashi". Then, the registration and settlement device 10 executes the settlement process (step 6) of customer a by the operation of the clerk in charge "Kobayashi". In other words, the registration and settlement device 10 executes the process in the following order: registration of one item for customer a by the sales clerk "Kobayashi" → registration of one item for customer b by the sales clerk "Takada" → settlement of all one item for customer b by the sales clerk "Takada" → registration of two items for customer a by the sales clerk "Kobayashi" → settlement of all two items for customer a by the sales clerk "Kobayashi".

[0025] (Interrupt processing example 3) Furthermore, the registration and settlement device 10 can execute the settlement process for another customer (another clerk) after the registration process for a certain customer (a certain clerk). Specifically, the registration and settlement device 10 executes the registration process (steps 2 to 5) for one item of product for customer a through the operation of the clerk in charge "Kobayashi". Then, the registration and settlement device 10 executes the registration process (steps 2 to 5) for one item of product for customer b through the operation of the clerk in charge "Takada". Then, the registration and settlement device 10 executes the registration process (steps 2 to 5) for two items of product for customer a through the operation of the clerk in charge "Kobayashi". Then, the registration and settlement device 10 executes the settlement process (step 6) for customer b through the operation of the clerk in charge "Takada". Then, the registration and settlement device 10 executes the settlement process (step 6) for customer a through the operation of the clerk in charge "Kobayashi". In other words, the registration and settlement device 10 executes the following process in order: registration of one item for customer a by the sales clerk "Kobayashi" → registration of one item for customer b by the sales clerk "Takada" → registration of two items for customer a by the sales clerk "Kobayashi" → settlement of all one item for customer b by the sales clerk "Takada" → settlement of all two items for customer a by the sales clerk "Kobayashi". In this example, settlement processing for customer b (sales clerk "Takada") is executed after registration processing of two items for customer a (sales clerk "Kobayashi")

[0026] (Processing by multiple registered settlement devices 10) As shown in Fig. 1, multiple registered settlement devices 10 are installed in a store. The registered settlement devices 10 are capable of communicating with each other. Therefore, pre-subtotal information (Fig. 4(A)) generated and stored by a certain registered settlement device 10 can also be referred to (or obtained) by other registered settlement devices 10. In other words, when starting settlement at a certain registered settlement device 10, in addition to the pre-subtotal information of purchased products registered at that registered settlement device 10, the pre-subtotal information of purchased products registered at other registered settlement devices 10 can be referred to (obtained).

[0027] Therefore, the clerk in charge can register and settle the purchases of the customers he / she is in charge of using multiple registered settlement devices 10. For example, the clerk in charge can register two or more purchased items of the customers he / she is in charge of using multiple registered settlement devices 10, or can settle the purchases using a registered settlement device 10 different from the registered settlement device 10 that registered the purchased items.

[0028] (Example 1 of processing by multiple registered settlement devices 10) For example, the registration and settlement device 10-1 executes the registration process (steps 2 to 5) of the first item of product for customer A through the operation of the sales clerk "Kobayashi". Then, the other registration and settlement device 10-2 executes the registration process (steps 2 to 5) of the second item of product for customer A through the operation of the sales clerk "Kobayashi". Then, the registration and settlement device 10-2 executes the settlement process (step 6) for customer A through the operation of the sales clerk "Kobayashi". In other words, the sales clerk "Kobayashi" in charge processes (registers products and settles) for customer A using two registration and settlement devices 10 (registration and settlement device 10-1 and registration and settlement device 10-2) in the following manner: registering the first item of product for customer A through registration and settlement device 10-1 → registering the second item of product for customer A through registration and settlement device 10-2 → settling all two items for customer A through registration and settlement device 10-2.

[0029] The above example 1 is, for example, a situation in which after one item of product is registered at registered settlement device 10-1, another store clerk cuts in line at registered settlement device 10-1 (for example, while customer A is selecting a second item of product, registered settlement device 10-1 is used by another store clerk serving another customer), and a second item of product is registered at the vacant registered settlement device 10-2, or a situation in which one item of product is registered at registered settlement device 10-1 near the display position of the first item of product, and a second item of product is registered at registered settlement device 10-2 near the display position of the second item of product.

[0030] (Example 2 of processing by multiple registered settlement devices 10) For example, the registration and settlement device 10-1 executes the registration process (steps 2 to 5) of the first item of product for customer a through the operation of the sales clerk "Kobayashi". Then, the other registration and settlement device 10-1 executes the registration process (steps 2 to 5) of the second item of product for customer a through the operation of the sales clerk "Kobayashi". Then, the registration and settlement device 10-2 executes the settlement process (step 6) for customer a through the operation of the sales clerk "Kobayashi". In other words, the sales clerk "Kobayashi" in charge registers the first item of product for customer a through the registration and settlement device 10-1, registers the second item of product for customer a through the registration and settlement device 10-1, and settles all two items for customer a through the registration and settlement device 10-2, settling the account for customer a using a registration and settlement device (registration and settlement device 10-2) different from the registration and settlement device 10 (registration and settlement device 10-1) used to register the products for customer a (the first and second items of products).

[0031] The scene in Example 2 above is, for example, a scene in which after customer A registers items 1 and 2 at registered settlement device 10-1, another store clerk cuts in line at registered settlement device 10-1 (for example, while customer A is selecting item 3 (actually, three items that have not been purchased), the registered settlement device 10-1 is used by another store clerk who is serving another customer), and the payment is then made at the available registered settlement device 10-2.

[0032] (Immediate special price) The registered settlement device 10 applies the sale price based on the sale setting operation (hereinafter referred to as the real-time sale setting operation) in the registered settlement device 10 (or another registered settlement device 10). In other words, the sale price based on the real-time sale setting operation in one registered settlement device 10 is immediately applied to all registered settlement devices 10 on the LAN. Hereinafter, the sale price based on the real-time sale setting operation is referred to as the real-time sale price.

[0033] (Special pre-order price) The registered settlement device 10 may apply a special sale price to a product based on a special sale reservation. Hereinafter, the special sale price based on a special sale reservation is referred to as a reservation special sale price (or a special sale reservation price). For the sake of distinction, a price to which a special sale price (instant special sale price, reservation special sale price) is not applied may be referred to as a regular price.

[0034] Fig. 2 is a diagram showing an example of the configuration 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 of the registration and settlement devices 10 can communicate with each other via a LAN (which may be wired or wireless).

[0035] The sales system 1 may include a plurality of electronic shelf tags (not shown) that display product information (product name, price, etc.) of each product in the display case. The registration and settlement device 10 can communicate with the electronic shelf tags, for example, by a predetermined short-distance wireless communication method.

[0036] The sales system 1 may include one or more display devices (not shown, signage) that display information (guidance information, advertising information) about stores and products. The registration and settlement device 10 can communicate with the signage, for example, via a LAN or by a predetermined short-distance wireless communication method.

[0037] The sales system 1 may include a store controller (not shown; in-store server) and a management device (not shown; personal computer). The registration and settlement device 10 is capable of communicating with the store controller and the management device via a LAN. The registration and settlement device 10 may also be capable of communicating with an external device (for example, an external server installed at a headquarters or data center; it may be a cloud server) via another device (for example, a store controller, etc.) or without via another device.

[0038] Fig. 3 is a diagram showing an example of the configuration of the registration and settlement device 10. As shown in Fig. 3, the registration and settlement device 10 includes a CPU 101, a memory unit (ROM, RAM, HDD, SDD, etc.) 102, a store clerk display unit 103, a customer display unit 104, a scanner unit 105, a weighing 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).

[0039] CPU 101 executes programs to execute various processes for realizing the functions of registered settlement device 10. Memory unit 102 stores various information. For example, it stores programs executed by CPU 101. Memory unit 102 also stores information acquired from the outside and information generated or referenced by CPU 101 (for example, the information shown in FIG. 4, screen information, message information, print format information, and identification information of the own device (device number)).

[0040] The clerk display unit 103 is disposed facing the clerk. The clerk display unit 103 is configured as a touch display, and displays various operation screens (FIGS. 5 to 34) to the clerk, and accepts various operations from the clerk. The customer display unit 104 is disposed facing the customer. The customer display unit 104 displays various screens to the customer. The customer display unit 104 is configured as a touch display, and may accept various operations from the customer.

[0041] Scanner unit 105 optically reads the coded information. For example, scanner unit 105 reads a barcode printed on a customer's membership card (or displayed on a customer's mobile terminal, etc.). When a product with a barcode is sold in a store, scanner unit 105 reads the barcode of the product.

[0042] The weighing unit 106 weighs the weight of the object (the container, the product contained in the container, etc.) placed on the scale platform 106a, and outputs data indicating the weighed value to the CPU 101. After acquiring the weighed value from the weighing unit 106, the CPU 101 subtracts the weight of the container (the container weight) from the weighed value (tare subtraction) to calculate the weight of the product placed on the scale platform 106a (purchase weight).

[0043] The operation unit 107 has various operation keys (number entry key, cancel key, tare key, add key, item number key, execute key, etc.) for receiving various operations from the store clerk. 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 receipts and issues (outputs) them from the issuing port. The printing unit 108 may print labels instead of or in addition to receipts and issue (output) them from the issuing port.

[0044] Drawer 109 has a storage section for storing currency (banknotes, coins) and the like, and the storage section is designed to be pulled out to the front in response to an operation by a store clerk. The store clerk stores currency received as payment from a customer in drawer 109, and if there is change, takes out currency corresponding to the amount of the change from drawer 109 and hands it over to the customer. Drawer 109 may also store coupons and the like collected from customers.

[0045] 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 by wired or wireless LAN, but may be communication by other communication methods.

[0046] FIG. 4 shows an example of various information. FIG. 4(A) shows an example of pre-subtotal information. In step 5, the registered settlement device 10 generates pre-subtotal information as shown in FIG. 4(A) and stores it in the storage unit 102. The pre-subtotal information shown in FIG. 4(A) includes a clerk code (the clerk code of the clerk in charge), a device number (the device number of the registered settlement device 10), sales price determination data, and a processing category. The sales price determination data includes a product code that identifies the purchased product, the unit price of the purchased product (discounted unit price / discounted unit price if a discount or price reduction is applied to the purchased product), the purchase weight, and the sales price. The processing category is information indicating whether the subtotal button has been operated or whether the settlement has been completed. The processing category value "0" is before the settlement has started (initial value). The processing category value "1" is during settlement. The processing category value "2" is the settlement completion.

[0047] FIG. 4(B) is an example of post-subtotal information. The registered settlement device 10 generates one piece of post-subtotal information as shown in FIG. 4(B) from one or more pieces of pre-subtotal information (FIG. 4(A)) of the customer who is the subject of settlement in step 6. More specifically, when the subtotal button (a subtotal button that also specifies a store clerk code) is operated, the registered settlement device 10 extracts one or more pieces of pre-subtotal information (FIG. 4(A)) that includes the store clerk code and has a processing category value of "0 (before settlement begins)", and generates one piece of post-subtotal information as shown in FIG. 4(B) based on the one or more pieces of pre-subtotal information extracted. The registered settlement device 10 updates the processing category value for each of the one or more pieces of pre-subtotal information extracted from "0 (before settlement begins)" to "1 (during settlement)".

[0048] The post-subtotal information shown in FIG. 4(B) includes a transaction number (e.g., date + sequence number), a clerk code (the clerk code of the clerk in charge), a total amount (the sum of the sales prices of product 1, product 2, ...), and product 1, product 2, ..., product N. Product N is the number N of products purchased by the customer (the number of pieces of pre-subtotal information for the customer). For example, if the number of products purchased by the customer (pre-subtotal information for the customer) is three, the items will be product 1, product 2, and product 3. Product 1 is information about one purchased product. Product 1 includes the device number of the registration settlement device 10 that registered the one purchased product (steps 2 to 5), and the sales price confirmation data for the one purchased product. The same applies to products 2, ..., product N.

[0049] Note that since the pre-subtotal information (Fig. 4(A)), which includes the machine number, can be referenced as log information that can identify the machine in which each product was registered (the processing category value is updated as the processing progresses but is not deleted), the post-subtotal information (Fig. 4(B)) does not need to include the machine number. In relation to the above, the pre-subtotal information may include the generation date and time and a sequence number.

[0050] The registered settlement device 10 may generate post-subtotal information (FIG. 4(B)) from one or more pieces of pre-subtotal information (FIG. 4(A)) and execute settlement processing based on the generated post-subtotal information (FIG. 4(B)), or may execute settlement processing directly from one or more pieces of pre-subtotal information (FIG. 4(A)). In other words, the registered settlement device 10 does not have to generate post-subtotal information (FIG. 4(B)).

[0051] FIG. 4(C) is an example of a product master (basic product information). The product master shown in FIG. 4(C) includes a product code, a product name, a unit price (normal price), and a measurement category. The measurement category value "0" is an indefinite weight. The measurement category value "1" is a fixed price. A product in the measurement category "0 (indefinite weight)" is a product whose selling price is determined by the weight, such as side dish A (described later). A product in the measurement category "1 (fixed price)" is a product whose selling price is determined, such as XX yen per item. For a product in the measurement category "1 (fixed price)", the unit price is the selling price for one product, but for a product in the measurement category "0 (indefinite weight)", the selling price is calculated from the unit price and the purchase weight. The registered settlement device 10 may acquire (receive) a product master from another device (for example, a store controller (not shown), an external server (not shown)) and store it in the storage unit 102.

[0052] FIG. 4(D) is an example of real-time special sale setting information. The registered settlement device 10 generates real-time special sale setting information as shown in FIG. 4(D) based on the real-time special sale setting operation, and stores it in the memory unit 102. The real-time special sale setting information shown in FIG. 4(D) includes a product code, a setting category, and a discount rate / discount amount. The setting category (similar to the setting category of the special sale reservation setting information) is information indicating whether a discount (discount rate) or a discount (discount amount) has been set by the real-time special sale setting operation. For example, a setting category value of "1" is a discount. A setting category value of "2" is a discount. The discount rate / discount amount (similar to the discount rate / discount amount of the special sale reservation setting information) is a discount rate or a discount amount.

[0053] For example, when an instantaneous sale setting operation is performed to discount a XX product by 10%, the registered settlement device 10 generates instantaneous sale setting information including the product code of the XX product, a setting category "1 (discount)", and a discount rate "10", and stores this information in the memory unit 102. When an instantaneous sale setting operation is performed to discount a XX product by 15 yen, the registered settlement device 10 generates instantaneous sale setting information including the product code of the XX product, a setting category "2 (discount)", and a discount amount "15", and stores this information in the memory unit 102.

[0054] The registered settlement device 10 may generate real-time special sale setting information as shown in FIG. 4(E) instead of the real-time special sale setting information as shown in FIG. 4(D) and store it in the storage unit 102. The real-time special sale setting information shown in FIG. 4(E) includes a product code, a setting category, a discount rate / discount amount, and a unit price (real-time special sale price). The unit price (real-time special sale price) can be calculated appropriately based on the discount rate (or discount amount) and the unit price (normal price) of the product master, so it is not included in the real-time special sale setting information in FIG. 4(D). However, the unit price (real-time special sale price) may be calculated based on the real-time special sale setting operation to generate real-time special sale setting information as shown in FIG. 4(E).

[0055] The instantaneous sale setting information (i.e., the instantaneous sale price) is valid until the end of the business day (the period during which the sales amount is recorded). Note that the instantaneous sale setting information (instantaneous sale price) being valid until the end of the business day means that it is invalid and does not apply on the next business day. Therefore, until the end of the business day may be until the closing time (or a time based on the closing time, for example, a predetermined time has passed since the closing time), or until post-closing business processing (closing processing) such as sales aggregation operations, which are also called closing processing (or closing processing), is performed, or until pre-opening business processing, which are also called opening processing, is performed.

[0056] The instant sale setting information is valid until the end of the business day, but may be invalidated before the end of the business day based on a specified operation (instant sale cancellation operation). In other words, the instant sale price set at a certain point in time is applied from that point onwards until the end of the business day, but if a specified operation (instant sale cancellation operation) is performed before the end of the business day, the application may be cancelled after the specified operation.

[0057] 4(F) is an example of sale reservation setting information. The registered settlement device 10 may obtain (receive) the sale reservation setting information from another device (e.g., a store controller (not shown), an external server (not shown)) and store it in the storage unit 102. The unit price (reservation sale price) can be calculated appropriately based on the discount rate (or discount amount) and the unit price (normal price) in the product master.

[0058] In addition, the registered settlement device 10 may acquire sale reservation setting information such as that shown in FIG. 4(G) from another device and store it in the memory unit 102, instead of the sale reservation setting information such as that shown in FIG. 4(F).

[0059] (Display on the store clerk display unit 103) 5 to 32 are examples of displays on the store clerk display unit 103 of the registration and settlement apparatus 10. FIG. The registration and settlement device 10 displays various screens for the store clerk. For example, the registration and settlement device 10 displays a menu screen (not shown) after powering on, and when the store clerk operates a registration button on the menu screen, displays a registration screen (initial screen) as shown in FIG.

[0060] At the start of the explanation of FIG. 5, all products are at regular price and no sale reservation is set for any product. At the start of the explanation of FIG. 5, pre-subtotal information for process category "0 (before settlement begins)" and pre-subtotal information for process category "1 (during settlement)" do not exist. The existence of pre-subtotal information for process category "0 (before settlement begins)" means the existence of a clerk serving a customer in a state after product registration but before settlement begins (a customer after product registration but before settlement begins). The existence of pre-subtotal information for process category "1 (during settlement)" means the existence of a clerk serving a customer in a state after settlement begins but before settlement is completed (a customer after settlement begins but before settlement is completed). In other words, at the start of the explanation of FIG. 5, it is assumed that there is no clerk serving a customer in a state after product registration but before settlement begins (a customer after product registration but before settlement begins) or a clerk serving a customer in a state after settlement begins but before settlement is completed (a customer after settlement begins but before settlement is completed).

[0061] The upper part of the registration screen shown in FIG. 5 (as well as other registration screens) is provided with a display area for displaying the tare weight, product name, purchase weight, unit price, sales price, total number, total amount (price), etc. The right-hand center part of the registration screen shown in FIG. 5 (as well as other registration screens) displays a plurality of tabs (prepared food tab, leafy vegetable tab, root vegetable tab, store clerk tab, container tab) that can be selected by operation (touch), and buttons (prepared food A button, prepared food B button, prepared food C button, prepared food D button, prepared food E button corresponding to the prepared food tab in FIG. 5) that correspond to the selected tab (prepared food tab in FIG. 5). The tabs are switched in response to the store clerk's operation, but the registration and settlement device 10 may automatically switch tabs in response to the progress of processing. The lower part of the registration screen shown in FIG. 5 (as well as other registration screens and settlement screens) displays various buttons (instant sale setting button, instant sale cancellation button, etc.). The instant sale setting button is a button that accepts an instant sale setting operation. The instant sale cancellation button is a button that accepts an instant sale cancellation operation.

[0062] In addition, on the registration screen shown in FIG. 5 (as well as other registration screens and settlement screens), buttons shown in solid frames (e.g., the prepared food A button through the prepared food E button, the instant sale setting button, etc.) are valid buttons (operable buttons), while buttons shown in dashed frames (e.g., the instant sale cancellation button, the deposit / current button) are invalid buttons (inoperable buttons). Invalid buttons (inoperable buttons) may be displayed in a grayed-out state or may be hidden. Invalid buttons may also display an error message after operation.

[0063] (Transaction at normal price) 6 to 16 are display examples in the scene of a transaction at normal price. It is assumed that when the registration and settlement device 10 is displaying the registration screen (initial screen) of Fig. 5, a customer (customer c) instructs to purchase 150 g of side dish A (normal price is 400 yen / 100 g), and the purchase is accepted by the store clerk "Suzuki".

[0064] When the sales clerk "Suzuki" operates the prepared food A button on the registration screen of Fig. 5, the registration settlement device 10 displays a registration screen as shown in Fig. 6. Because the product to be purchased has been specified, the registration settlement device 10 switches from the prepared food tab to the clerk tab in preparation for input of the clerk code (operation of the clerk button), but because the sales price has not been finalized, operation of the clerk buttons (Kobayashi button, Tanaka button, Suzuki button, Nakamura button, Sato button, Takada button) is invalid.

[0065] When the store clerk "Suzuki" sets the tare weight on the registration screen of Figure 6 (for example, when he operates the tare button and weighs the tare (empty) (the measured weight is 10 g)), the registration settlement device 10 displays a registration screen such as that shown in Figure 7.

[0066] When the store clerk "Suzuki" weighs side dish A in a tare weight (10g) on ​​the registration screen of Fig. 7 (the measured weight including the tare weight is 160g), the registration and settlement device 10 displays a registration screen such as that shown in Fig. 8. After the weight stabilizes, the registration and settlement device 10 calculates the selling price (600 yen) from the unit price of side dish A (400 yen / 100g) and the purchase weight (150g). Because the selling price has been confirmed on the registration screen of Fig. 8, operation of the clerk button is enabled.

[0067] When the responsible clerk "Suzuki" operates his / her own Suzuki button on the registration screen of FIG. 8, the registration settlement device 10 displays a registration screen as shown in FIG. 9. Because the clerk button was operated (entering the clerk code), the registration settlement device 10 returns the display from the clerk tab to the side dish tab. The registration settlement device 10 also generates pre-subtotal information for side dish A based on the operation of the Suzuki button and stores it in the memory unit 102. A subtotal button for clerk Suzuki (a subtotal button that also specifies the clerk code of clerk "Suzuki") is displayed on the left center of the registration screen shown in FIG. 9. In other words, the registration settlement device 10 displays a subtotal button for the clerk who last operated the clerk button on the clerk tab on the left center. The subtotal button for clerk Suzuki displays "Suzuki" to indicate that it is for clerk Suzuki.

[0068] If customer c does not purchase any products other than side dish A (i.e., if he or she proceeds to checkout), the sales clerk "Suzuki" operates the subtotal button for sales clerk Suzuki on the registration screen in Figure 9. If customer c purchases products other than side dish A, the sales clerk "Suzuki" operates the product button for the next product to be purchased on the registration screen in Figure 9.

[0069] The registration and settlement device 10 may erase the total information (1 item, 600 yen) in the upper right corner of the screen when a predetermined time (e.g., 5 seconds) has elapsed since the start of displaying the registration screen in Fig. 9. The registration and settlement device 10 erases the total information (Fig. 10) if the product button is operated on the registration screen in Fig. 9 before a predetermined time has elapsed since the start of displaying the registration screen in Fig. 9. The registration and settlement device 10 also displays the settlement screen when the subtotal button for store clerk Suzuki is operated on the registration screen in Fig. 9.

[0070] When the registration and settlement device 10 is displaying the registration screen of Figure 9, customer C indicates that he / she would like to purchase 500 yen worth of side dish C (normal price is 380 yen / 100g) as the second item (the desired purchase amount is 500 yen), and the order is accepted by the store clerk in charge, "Suzuki."

[0071] When the clerk "Suzuki" operates the prepared dish C button on the registration screen in Fig. 9, the registration and settlement device 10 displays a registration screen as shown in Fig. 10. Because a product to be purchased has been specified, the registration and settlement device 10 switches from the prepared dish tab to the clerk tab in preparation for input of the clerk code (operation of the clerk button), but because the sales price has not been finalized, operation of the clerk button is invalid. The "1" displayed on the Suzuki button indicates that one piece of pre-subtotal information (pre-subtotal information for the first item of prepared dish A) for customer c, who is handled by clerk "Suzuki," has been stored. Note that because registration of prepared dish C has begun (because it is no longer possible to proceed to payment), operation of the subtotal button for clerk Suzuki is invalid.

[0072] When the clerk "Suzuki" sets the tare weight on the registration screen of Figure 10 (for example, when he operates the tare button and weighs the tare (empty) (the measured weight is 8g)), the registration settlement device 10 displays a registration screen such as that shown in Figure 11.

[0073] When the store clerk "Suzuki" in charge puts side dish C into a tare (8 g) and weighs it (the measured value is 138 g) on ​​the registration screen of Fig. 11, the registration and settlement device 10 displays a registration screen such as that shown in Fig. 12. After the weight stabilizes, the registration and settlement device 10 calculates the selling price (494 yen) from the unit price of side dish C (380 yen / 100 g)) and the purchase weight (130 g). Because the selling price has been confirmed on the registration screen of Fig. 12, operation of the clerk button is enabled.

[0074] When the store clerk "Suzuki" operates his / her own Suzuki button on the registration screen in Fig. 12, the registration settlement device 10 displays a registration screen as shown in Fig. 13. Because the clerk button was operated (the clerk code was entered), the registration settlement device 10 returns the display from the clerk tab to the prepared food tab. The registration settlement device 10 also generates pre-subtotal information for prepared food C based on the operation of the Suzuki button, and stores it in the memory unit 102. Because the registration of prepared food C has been completed (because payment can now be proceeded to), operation of the subtotal button for store clerk Suzuki is enabled.

[0075] If customer c does not purchase any products other than side dishes A and C (if customer c proceeds to checkout), the sales clerk "Suzuki" operates the subtotal button for sales clerk Suzuki on the registration screen in Fig. 13. If customer c purchases products other than side dishes A and C, the sales clerk "Suzuki" operates the product button for the next product to be purchased on the registration screen in Fig. 13.

[0076] The registration and settlement device 10 may erase the total information (2 items, 1,094 yen) in the upper right corner of the screen when a predetermined time (e.g., 5 seconds) has elapsed since the start of displaying the registration screen in Fig. 13. The registration and settlement device 10 also erases the total information if a product button is operated before a predetermined time has elapsed since the start of displaying the registration screen in Fig. 13. The registration and settlement device 10 displays the settlement screen (Fig. 14) when the subtotal button for store clerk Suzuki is operated on the registration screen in Fig. 13.

[0077] When the clerk "Suzuki" operates the subtotal button for clerk Suzuki on the registration screen in Fig. 13, the registration settlement device 10 displays a settlement screen (subtotal screen) as shown in Fig. 14. In other words, because the clerk code for clerk "Suzuki" was entered by operating the subtotal button for clerk Suzuki, the registration settlement device 10 generates (for example, generates post-subtotal information) based on two pieces of pre-subtotal information (pre-subtotal information for side dish A generated and stored based on the operation of the Suzuki button on the registration screen in Fig. 8, and pre-subtotal information for side dish C generated and stored based on the operation of the Suzuki button on the registration screen in Fig. 12), and displays the settlement screen as shown in Fig. 14. In addition, based on the operation of the subtotal button for clerk Suzuki, the registration settlement device 10 updates the processing category of the pre-subtotal information for that clerk (the above two pieces of pre-subtotal information) from "0 (before settlement begins)" to "1 (during settlement)".

[0078] The upper part of the settlement screen shown in FIG. 14 (as well as other settlement screens) is provided with a display area for displaying the container weight and the purchase weight. The registered settlement device 10 can display the container weight and the purchase weight while displaying the settlement screen. In other words, the registered settlement device 10 can be used as a weighing device during settlement processing. For example, when the registered settlement device 10 is left with the settlement screen (customer c's settlement screen) of FIG. 14 displayed (for example, when the sales clerk "Suzuki" in charge moves to another place while the settlement screen of FIG. 14 is displayed and does not return for a long time), the sales clerk in charge of another customer operates the container button on the settlement screen to weigh a container (empty) for containing the purchased goods of the other customer, and if the sales clerk puts the purchased goods of the other customer in the container and weighs them, the registered settlement device 10 displays the purchase weight of the purchased goods of the other customer in the upper display area. Therefore, it is possible to prepare the purchased goods of another customer while maintaining the settlement screen during settlement of a certain customer.

[0079] When the clerk "Suzuki" operates the deposit / present button on the settlement screen of FIG. 14, the registration settlement device 10 pops up a small screen (deposit amount input screen) as shown in FIG.

[0080] When the clerk "Suzuki" in charge inputs 1,181 (yen) as the deposit amount received from customer c on the small screen in FIG. 15 and presses the Confirm button, the registration settlement device 10 clears the small screen and displays a settlement screen (settling completion screen) as shown in FIG. 16. After a predetermined time (e.g., 5 seconds) has elapsed, the registration settlement device 10 displays the registration screen (initial screen) shown in FIG. 5. In addition, based on the operation of the Confirm button, the registration settlement device 10 updates the processing category of the pre-subtotal information referenced in the settlement process (pre-subtotal information including the clerk code of the clerk "Suzuki" in charge) from "1 (settling in progress)" to "2 (settling completed)."

[0081] (Setting instant sale prices) 17 to 20 are display examples in which an instantaneous special sale price is set. It is assumed that the registration and settlement device 10 displays the registration screen (initial screen) of FIG.

[0082] When a certain store clerk (for example, "Kobayashi") operates the instant sale setting button on the registration screen of FIG. 5, the registration and settlement device 10 pops up a small screen (instant sale setting screen) as shown in FIG. 17. The small screen of FIG. 17 is a screen for setting the discount rate (or discount amount). For example, when setting a 10% discount, the store clerk inputs the quantity "10" and operates the discount button (or operates the discount button and inputs the quantity "10"). When setting a 20 yen discount, the store clerk inputs the quantity "20" and operates the discount button (or operates the discount button and inputs the quantity "20"). When canceling (cancelling) the setting of the instant sale price, the store clerk operates the cancel (cancel setting) button (the same applies to the cancel (cancel setting) button of FIG. 18 and the cancel (cancel setting) button of FIG. 19).

[0083] The setting of 0% discount may be rejected as an input error, or may be accepted as effectively no discount. The same applies to the setting of 0 yen discount.

[0084] When the store clerk "Kobayashi" sets a 10% discount on the small screen in FIG. 17, the registration and settlement device 10 erases the small screen and displays a registration screen as shown in FIG. 18. A message is displayed on the center left side of the registration screen shown in FIG. 18 instructing the user to use a button to select the product (one or more) for which the 10% discount will be set (applied). Also, a cancel (cancel setting) button and an execute button are displayed on the center left side of the registration screen shown in FIG. 18. To cancel (cancel) the 10% discount, the store clerk operates the cancel (cancel setting) button. Note that, because one or more products have not been selected on the registration screen in FIG. 18, operation of the execute button is disabled.

[0085] The sales clerk "Kobayashi" switches between tabs (prepared dishes tab, leafy vegetables tab, root vegetables tab) and selects one or more products to which a 10% discount will be applied. Note that switching between tabs that are unrelated to the instantaneous sale price setting (sales clerk tab, container tab) is disabled.

[0086] When the store clerk "Kobayashi" operates the side dish A button and the side dish E button on the registration screen of FIG. 18 (i.e., when operation A and side dish E are selected), the registration settlement device 10 displays a registration screen as shown in FIG. 19. In the registration screen shown in FIG. 19, the side dish A button and the side dish E button operated (selected) by the store clerk "Kobayashi" are displayed in a display mode indicating that they are selected (bold frame in the figure). Note that, if the store clerk "Kobayashi" wishes to cancel the selection of side dish A (as well as side dish E) (to stop the application of the 10% discount), he or she operates the side dish A button again before operating the execute button. When the side dish A button is operated again, the display mode of the side dish A button will no longer indicate that it is selected (it will be framed in a normal thickness). Also, a message instructing the operation of the execute button is displayed on the left center of the registration screen shown in FIG. 19.

[0087] When the store clerk "Kobayashi" operates the execute button on the registration screen of Fig. 19, the registration and settlement device 10 displays a registration screen as shown in Fig. 20. The "10%" on the prepared dish A button and the prepared dish E button indicates that a 10% discount has been applied as the instantaneous special sale price. In addition, because the instantaneous special sale price has been applied (because an item eligible for cancellation has been created), the operation of the instantaneous special sale release button is enabled on the registration screen of Fig. 20.

[0088] 19, the registered settlement device 10 generates real-time special sale setting information for side dishes A and E, and stores it in the memory unit 102. Specifically, the registered settlement device 10 generates real-time special sale setting information (FIG. 3(D)) including the product code of side dish A, a setting category "1 (discount)", and a discount rate "10", and real-time special sale setting information (FIG. 3(D)) including the product code of side dish E, a setting category "1 (discount)", and a discount rate "10", and stores it in the memory unit 102. The registered settlement device 10 may also generate real-time special sale setting information (FIG. 3(E)) for side dish A, including the product code of side dish A, a setting category "1 (discount)", a discount rate "10", and a real-time special sale unit price "360", and store it in the memory unit 102. Similarly, for side dish E, real-time special sale setting information (FIG. 3(E)) including the real-time special sale unit price may be generated and stored in storage unit 102.

[0089] (Transactions at instant special prices) 21 to 25 are display examples in the scene of a transaction at a real-time special sale price. It is assumed that when the registration and settlement device 10 displays the registration screen (initial screen) of Fig. 20, a customer d instructs to purchase 200 g of side dish A (real-time special sale price is 360 yen / 100 g), and the clerk "Tanaka" accepts the purchase.

[0090] When the sales clerk "Tanaka" operates the prepared food A button on the registration screen of FIG. 20, the registration settlement device 10 displays a registration screen as shown in FIG. 21. On the registration screen shown in FIG. 21, "(10% off) 360" is displayed in the unit price display area. Also, on the left center, a message "Registering immediate special product" is displayed to the effect that an item at a real-time special price is being registered. Note that, although the message "Registering immediate special product" is displayed in this example, it is sufficient to notify that an item at a real-time special price is being registered; for example, instead of or in addition to a message, the background color of the left center (all or part of the left center) may be changed.

[0091] When the clerk in charge, "Tanaka", sets the tare weight on the registration screen in Figure 21 (for example, by operating the tare button and weighing the tare (empty) (the measured weight is 10 g)), the registration settlement device 10 displays a registration screen such as that shown in Figure 22.

[0092] When the sales clerk "Tanaka" weighs the side dish A in a tare weight (10 g) on ​​the registration screen of Fig. 22 (the weight including the tare weight is 210 g), the registration settlement device 10 displays a registration screen as shown in Fig. 23. After the weight stabilizes, the registration settlement device 10 calculates the selling price (720 yen) from the unit price of side dish A (360 (yen / 100 g)) and the purchase weight (200 g).

[0093] When the responsible store clerk "Tanaka" operates his / her own Tanaka button on the registration screen of FIG. 23, the registration settlement device 10 displays a registration screen as shown in FIG. 24. Because the clerk button was operated (entering the clerk code), the registration settlement device 10 returns the display from the clerk tab to the side dish tab. The registration settlement device 10 also generates pre-subtotal information for side dish A based on the operation of the Tanaka button and stores it in the memory unit 102. A subtotal button for clerk Tanaka (a subtotal button that also specifies the clerk code of clerk "Tanaka") is displayed on the left center of the registration screen shown in FIG. 24. The subtotal button for clerk Tanaka displays "Tanaka" to indicate that it is for clerk Tanaka.

[0094] If customer d does not purchase any products other than side dish A (i.e., if customer d proceeds to checkout), the sales clerk "Tanaka" operates the subtotal button for sales clerk "Tanaka" on the registration screen in Fig. 24. If customer d purchases products other than side dish A, the sales clerk "Tanaka" operates the product button for the next product to be purchased on the registration screen in Fig. 24.

[0095] The registration and settlement device 10 may erase the total information (1 item, 720 yen) in the upper right corner of the screen after a predetermined time (e.g., 5 seconds) has elapsed. The registration and settlement device 10 erases the total information if the product button is operated on the registration screen in Fig. 24 before a predetermined time has elapsed since the start of displaying the registration screen in Fig. 24. The registration and settlement device 10 also displays the settlement screen if the subtotal button for clerk Tanaka is operated on the registration screen in Fig. 24.

[0096] When the clerk "Tanaka" operates the subtotal button for clerk Tanaka on the registration screen of FIG. 24, the registration settlement device 10 displays a settlement screen (sub-screen, corresponding to FIG. 14), not shown in the figure. When the clerk "Tanaka" operates the deposit / present button on the settlement screen (sub-screen), the registration settlement device 10 pops up a small screen (deposit amount input screen, small screen shown in FIG. 15), not shown in the figure. When the clerk "Tanaka" inputs 780 (yen) as the deposit amount received from customer d on the small screen and operates the confirm button, the registration settlement device 10 erases the small screen and displays a settlement screen (settlement completion screen) as shown in FIG. 25. When a predetermined time (e.g., 5 seconds) has elapsed, the registration settlement device 10 displays the registration screen (initial screen) shown in FIG. 20. In addition, the registered settlement device 10 updates the processing category of the pre-subtotal information for clerk Tanaka from "0 (before settlement begins)" to "1 (settlement in progress)" based on the operation of the subtotal button for that clerk, and updates the processing category of the pre-subtotal information for that clerk from "0 (settlement in progress)" to "2 (settlement completed)" based on the operation of the confirm button.

[0097] (Resetting of instant sale prices) 26 to 29 are display examples in a scene where an instantaneous special sale price is reset (an instantaneous special sale price is set after an instantaneous special sale price is set). It is assumed that the registration and settlement device 10 displays the registration screen (initial screen) of FIG. 20.

[0098] When a certain store clerk (for example, "Tanaka") operates the instant sale setting button on the registration screen of FIG. 20, the registration and settlement device 10 pops up a small screen (instant sale setting screen) as shown in FIG.

[0099] When the store clerk "Tanaka" sets a 15% discount on the small screen of FIG. 26, the registration and settlement device 10 erases the small screen and displays a registration screen as shown in FIG. 27. A message is displayed on the center left side of the registration screen shown in FIG. 27 instructing the user to use a button to select the product (one or more) for which the 15% discount will be set (applied). Also, a cancel (cancel setting) button and an execute button are displayed on the center left side of the registration screen shown in FIG. 27. To cancel (cancel) the 15% discount, the store clerk operates the cancel (cancel setting) button. Note that, because one or more products have not been selected on the registration screen of FIG. 27, operation of the execute button is disabled.

[0100] When the store clerk "Tanaka" operates the side dish A button and the side dish B button on the registration screen of FIG. 27 (i.e., when operation A and side dish B are selected), the registration settlement device 10 displays a registration screen as shown in FIG. 28. In the registration screen shown in FIG. 28, the side dish A button and the side dish B button operated (selected) by the store clerk "Tanaka" are displayed in a display mode indicating that they are selected (shown in a thick frame in the figure). Note that if the store clerk "Tanaka" wishes to cancel the selection of side dish A (as well as side dish B) (to stop the application of the 15% discount), he or she operates the side dish A button again before operating the execute button. When the side dish A button is operated again, the display mode of the side dish A button will no longer indicate that it is selected (it will be framed in a normal thickness).

[0101] When the store clerk "Tanaka" operates the execute button on the registration screen of Fig. 28, the registration and settlement device 10 displays the registration screen (initial screen) as shown in Fig. 29. The "15%" on the prepared dish A button and the prepared dish B button indicates that a 15% discount is being applied as an immediate sale price.

[0102] In addition, based on the operation of the execute button on the registration screen of Figure 28, the registration settlement device 10 updates the instantaneous special sale setting information for side dish A stored in the memory unit 102 (discount rate from "10%" to "15%), generates instantaneous special sale setting information for side dish B, and stores it in the memory unit 102.

[0103] (Release of instant special sale price) 30 to 32 are examples of displays when the setting of an instantaneous special sale price is cancelled. It is assumed that the registration and settlement device 10 displays the registration screen (initial screen) of FIG.

[0104] When a certain store clerk (for example, "Sato") operates the instant sale cancellation button on the registration screen of FIG. 29, the registration settlement device 10 displays a registration screen as shown in FIG. 30. A message is displayed on the center left side of the registration screen shown in FIG. 30 instructing the user to use a button to select the product (one or more) for which the instant sale price setting is to be cancelled. Also, a cancel (cancel cancellation) button and an execute button are displayed on the center left side of the registration screen shown in FIG. 30. To cancel (cancel) the cancellation, the store clerk operates the cancel (cancel cancellation) button. Note that, since one or more products are not selected on the registration screen of FIG. 30, the operation of the execute button is disabled. Also, since no instant sale price is set for side dish C (similarly for side dish D) (since it is not subject to cancellation), the side dish C button cannot be operated (selected).

[0105] When the store clerk "Sato" operates the side dish A button on the registration screen of FIG. 30 (i.e., when operation A is selected), the registration settlement device 10 displays a registration screen as shown in FIG. 31. In the registration screen shown in FIG. 31, the side dish A button operated (selected) by the store clerk "Sato" is displayed in a display mode indicating that it is selected (shown in a thick frame in the figure). If the store clerk "Sato" wishes to cancel the selection of side dish A (to stop the release), he or she operates the side dish A button again before operating the execute button. When the side dish A button is operated again, the display mode of the side dish A button will no longer indicate that it is selected (it will have a normal thick frame). Also, a message instructing the user to operate the execute button is displayed on the left center of the registration screen shown in FIG. 31.

[0106] When the store clerk "Sato" operates the execute button on the registration screen in Fig. 31, the registration settlement device 10 displays the registration screen (initial screen) as shown in Fig. 32. The "10%" on the side dish A button has been erased. Note that because the instant sale price is applied to side dishes B and E (because there are still items eligible for cancellation), the operation of the instant sale cancellation button remains valid on the registration screen in Fig. 32.

[0107] Furthermore, the registration and settlement device 10 erases the real-time special sale setting information for the side dish A stored in the storage unit 102 (or may set a flag indicating that the information is invalid) based on the operation of the execute button on the registration screen of FIG.

[0108] The display of the store clerk display unit 103 of the registered settlement device 10 has been explained above using Figures 5 to 32. However, since the registered settlement device 10 accepts operations to set a special sale price (instant special sale price) and to cancel the setting of a special sale price (instant special sale price) on the registration screen, etc. (Figures 17 to 20, Figures 26 to 32), the store (on-site) can set a suitable special sale price (instant special sale price) as appropriate (depending on the sales of each product on the day, etc.), or cancel it as necessary.

[0109] (Instant sale setting button, Instant sale cancellation button) The immediate discount sale setting button can be operated when the registration screen (initial screen) or the checkout screen (checkout completion screen) is displayed and there is no pre-subtotal information for process type "0 (before checkout begins)" (i.e., there is no customer after product registration and before checkout begins). In Figs. 5 to 32, Figs. 5, 20, 29, and 32 are registration screens (initial screens), and Figs. 16 and 25 are checkout screens (checkout completion screens), but in either case, there is no pre-subtotal information for process type "0 (before checkout begins)," so the immediate discount sale setting button can be operated.

[0110] For example, during busy times, there may be a continuous stream of customers who have registered products but have not yet started payment (there may be a continuous period of time when there is one or more pieces of pre-subtotal information for processing category "0 (before payment begins)"), and it may become impossible to operate the immediate sale setting button (to set the immediate sale price) for a while. As appropriate, the immediate sale setting button may be made operable even when pre-subtotal information for processing category "0 (before payment begins)" exists (i.e., when there are customers who have registered products but have not yet started payment), so that the immediate sale setting button can be operated (so that the immediate sale price can be set). For example, when the registration screen (initial screen) or payment screen (payment completion screen) is displayed, the immediate sale setting button may be made operable regardless of whether pre-subtotal information for processing category "0 (before payment begins)" exists or not. For example, the immediate discount sale setting button may be made operable at any time (when a screen other than the registration screen (initial screen) or the settlement screen (settlement completion screen) is displayed) regardless of whether pre-subtotal information for processing category "0 (before settlement begins)" is present or not.

[0111] If the instant sale price is set by operating the instant sale setting button when pre-subtotal information for processing category "0 (before settlement begins)" exists, the instant sale price setting is reflected in the pre-subtotal information for processing category "0 (before settlement begins)". For example, if the instant sale setting button is operated to set an instant sale price for a product when pre-subtotal information for processing category "0 (before settlement begins)" exists, which includes price determination data calculated at the regular price of a product, exists (i.e., pre-subtotal information for processing category "0 (before settlement begins)" exists, which includes price determination data for the product for which an instant sale price has been set), the price determination data of the pre-subtotal information may be updated immediately (updated to the price determination data calculated at the instant sale price), or the price determination data of the pre-subtotal information may be updated at the time of subtotal. The same applies when setting an instant sale price for a product for which an instant sale price has already been set (for example, changing from a 10% discount to a 15% discount).

[0112] In addition, when pre-subtotal information of processing category "0 (before settlement begins)" exists and an immediate special sale price is set by operating the immediate special sale setting button, the pre-subtotal information of processing category "0 (before settlement begins)" may not reflect the immediate special sale price setting. In other words, the selling price data determined at the time of generating the pre-subtotal information may be maintained.

[0113] The immediate discount sale cancellation button can be operated when the registration screen (initial screen) or the checkout screen (checkout completion screen) is displayed and there is an item to be cancelled (when there is one or more items with an immediate discount sale price set), and there is no pre-subtotal information for processing category "0 (before checkout begins)". In Figs. 5 to 32, the immediate discount sale cancellation button can be operated on the registration screen (initial screen) in Fig. 20, the checkout screen (checkout completion screen) in Fig. 25, the registration screen (initial screen) in Fig. 29, and the registration screen (initial screen) in Fig. 32.

[0114] In addition, if there is an item to be released, the immediate discount sale release button may be made operable even if pre-subtotal information for processing category "0 (before checkout begins)" exists. For example, if there is an item to be released and the registration screen (initial screen) or checkout screen (checkout completion screen) is displayed, the immediate discount sale release button may be made operable regardless of whether pre-subtotal information for processing category "0 (before checkout begins)" exists. Also, for example, if there is an item to be released, the immediate discount sale release button may be made operable at any time, regardless of whether pre-subtotal information for processing category "0 (before checkout begins)" exists.

[0115] To avoid unnecessary trouble, the pre-subtotal information for processing category "0 (before checkout begins)" may not reflect the cancellation of the immediate special sale price. In other words, the selling price data determined at the time of generating the pre-subtotal information may be maintained to prevent a price increase after registration.

[0116] (Subtotal button) In the registration screen (initial screen) of Fig. 5 to which the checkout screen (checkout completion screen) of Fig. 16 is transferred, and in the registration screen (initial screen) of Fig. 20 to which the checkout screen (checkout completion screen) of Fig. 25 is transferred, that is, in the registration screen (initial screen) displayed after the transaction is completed, the subtotal button is not displayed (Figs. 5 and 25), but the subtotal button may be displayed in the registration screen (initial screen) displayed after the transaction is completed. Specifically, when the registration screen (initial screen) is displayed, if pre-subtotal information of processing category "0 (before checkout begins)" exists (if there is a customer who has registered products but has not yet started checkout), the subtotal button of the relevant clerk (the clerk whose clerk code is included in the pre-subtotal information; the clerk serving the customer) (the subtotal button that also specifies the clerk code of the relevant clerk) is displayed (displayed with or without a specified operation).

[0117] For example, in the case of the above-mentioned "Example 1 of interrupt processing" (where the processing is performed in the following order: registration of one product item for customer a by the sales clerk "Kobayashi" → registration of one product item for customer b by the sales clerk "Takada" → registration of two products for customer a by the sales clerk "Kobayashi" → settlement of all two items for customer a by the sales clerk "Kobayashi" → settlement of all one item for customer b by the sales clerk "Takada"), a subtotal button for sales clerk Takada (a subtotal button that also specifies the sales clerk code for sales clerk "Takada") is displayed on the registration screen (initial screen) after the settlement of all two items for customer a by sales clerk "Kobayashi" is completed. In other words, when the above registration screen (initial screen) is displayed, pre-subtotal information for processing category "0 (before settlement begins)" for sales clerk "Takada" in charge of customer b is present, so the subtotal button for sales clerk Takada is displayed. In this example 1, the store clerk "Takada" operates the subtotal button for Takada, and starts the settlement of all one item for customer b.

[0118] Also, for example, in the case of the above-mentioned "Example 2 of interrupt processing" (where the processing is performed in the following order: registration of one product item for customer a by the sales clerk "Kobayashi" → registration of one product item for customer b by the sales clerk "Takada" → settlement of all one item for customer b by the sales clerk "Takada" → registration of two products for customer a by the sales clerk "Kobayashi" → settlement of all two items for customer a by the sales clerk "Kobayashi"), a subtotal button for sales clerk Kobayashi (a subtotal button that also specifies the sales clerk code for sales clerk "Kobayashi") is displayed on the registration screen (initial screen) after sales clerk "Takada" has finished settling all one item for customer b. In other words, when the above registration screen (initial screen) is displayed, pre-subtotal information for processing category "0 (before settlement begins)" for sales clerk "Kobayashi" for customer a is present, so the subtotal button for sales clerk Kobayashi is displayed. In this example 2, the sales clerk "Kobayashi" starts registering the two items of merchandise for customer a without operating the subtotal button for sales clerk Kobayashi.

[0119] Also, for example, in the case of the above-mentioned "Example 3 of interrupt processing" (when the processing is performed in the following order: registration of one item for customer a by the sales clerk "Kobayashi" → registration of one item for customer b by the sales clerk "Takada" → registration of two items for customer a by the sales clerk "Kobayashi" → settlement of all one item for customer b by the sales clerk "Takada" → settlement of all two items for customer a by the sales clerk "Kobayashi"), a subtotal button for sales clerk Kobayashi is displayed on the registration screen (initial screen) after the completion of settlement of all one item for customer b by the sales clerk "Takada". In other words, when the above-mentioned registration screen (initial screen) is displayed, pre-subtotal information for the processing category "0 (before settlement begins)" for the sales clerk "Kobayashi" in charge of customer a is present, so the subtotal button for sales clerk Kobayashi is displayed. In this example 3, the sales clerk "Kobayashi" operates the subtotal button for sales clerk Kobayashi to start settlement of all two items for customer a.

[0120] When the registration screen (initial screen) is displayed, if pre-subtotal information for multiple clerks with the processing category "0 (before settlement begins)" exists (if there are multiple clerks serving customers who have registered products but have not yet started settlement), a subtotal button for each corresponding clerk may be displayed. When the registration screen (initial screen) is displayed, if pre-subtotal information for multiple clerks with the processing category "0 (before settlement begins)" exists, the clerk button for the corresponding clerk may be made operable in the clerk tab, and the subtotal button for the clerk corresponding to the clerk button operated in the clerk tab may be displayed. When the registration screen (initial screen) is displayed, if pre-subtotal information for only one clerk with the processing category "0 (before settlement begins)" exists (if there is one clerk serving customers who have registered products but have not yet started settlement), the clerk button for the corresponding clerk may be made operable in the clerk tab, and the subtotal button for that clerk may be displayed based on the operation of the clerk button for that clerk in the clerk tab. In other words, regardless of the number of store clerks who are serving customers after product registration but before the start of payment, the subtotal button for that store clerk may be displayed after the store clerk button in the store clerk tab is operated.

[0121] In addition, on the registration screen displayed after the registration of a certain store clerk (certain customer) is completed, a subtotal button for other store clerks (other customers) may be displayed.

[0122] Also, for example, in the case of the above-mentioned "Example 1 of Interrupt Processing" (where the processing is performed in the following order: registration of one product item for customer a by the sales clerk "Kobayashi" → registration of one product item for customer b by the sales clerk "Takada" → registration of two products for customer a by the sales clerk "Kobayashi" → settlement of all two products for customer a by the sales clerk "Kobayashi" → settlement of all one product item for customer b by the sales clerk "Takada"), on the registration screen after the sales clerk "Takada" has registered the first product item for customer b, a subtotal button for sales clerk Kobayashi may be displayed in addition to a subtotal button for sales clerk Takada, and on the registration screen after the sales clerk "Kobayashi" has registered the second product item for customer a, a subtotal button for sales clerk Takada may be displayed in addition to a subtotal button for sales clerk Kobayashi.

[0123] Also, for example, in the case of the above-mentioned "Example 2 of Interrupt Processing" (where the processing is executed in the following order: registration of one product item for customer a by the clerk in charge "Kobayashi" → registration of one product item for customer b by the clerk in charge "Takada" → settlement of all one item for customer b by the clerk in charge "Takada" → registration of two products for customer a by the clerk in charge "Kobayashi" → settlement of all two items for customer a by the clerk in charge "Kobayashi"), on the registration screen after the registration of the one product item for customer b by the clerk in charge "Takada", a subtotal button for clerk Kobayashi may be displayed in addition to a subtotal button for clerk Takada.

[0124] Also, for example, in the case of the above-mentioned "Example 3 of Interrupt Processing" (where the processing is performed in the following order: registration of one product item for customer a by the sales clerk "Kobayashi" → registration of one product item for customer b by the sales clerk "Takada" → registration of two products for customer a by the sales clerk "Kobayashi" → settlement of all one item for customer b by the sales clerk "Takada" → settlement of all two items for customer a by the sales clerk "Kobayashi"), on the registration screen after the registration of the first product item for customer b by the sales clerk "Takada", a subtotal button for sales clerk Kobayashi may be displayed in addition to a subtotal button for sales clerk Takada, and on the registration screen after the registration of the second product item for customer a by the sales clerk "Kobayashi", a subtotal button for sales clerk Takada may be displayed in addition to a subtotal button for sales clerk Kobayashi.

[0125] That is, when the registration screen to be displayed after the completion of registration is displayed, if there is pre-subtotal information of the processing category "0 (before settlement starts)" for multiple clerks, a subtotal button for each of the corresponding clerks may be displayed. Also, when the registration screen to be displayed after the completion of registration is displayed, if there is pre-subtotal information of the processing category "0 (before settlement starts)" for multiple clerks, the clerk button for the corresponding clerk may be made operable in the clerk tab, and the subtotal button for the clerk corresponding to the clerk button operated in the clerk tab may be displayed. Even if there is only pre-subtotal information of the processing category "0 (before settlement starts)" for one clerk when the registration screen to be displayed after the completion of registration is displayed, the clerk button for the corresponding clerk may be made operable in the clerk tab, and the subtotal button for the clerk may be displayed based on the operation of the clerk button for the clerk in the clerk tab. That is, regardless of the number of clerks serving customers in a state after product registration and before settlement starts, the subtotal button for the clerk may be displayed after the operation of the clerk button in the clerk tab.

[0126] (Reduction in discount rate and discount amount) In Figures 26 to 30, the discount rate for side dish A is increased from 10% to 15% (the discounted unit price is updated to be cheaper), but the discount rate may be decreased (the discounted unit price may be updated to be higher). Similarly, the discount amount may be decreased (the discounted unit price may be updated to be higher). Note that, although this has the same effect as canceling the discount, a 0% discount or 0 yen discount may be allowed.

[0127] (Output of information about instant sales) As shown in Figs. 20 to 32, the registration settlement device 10 displays information about real-time special sales on the clerk display unit 103. For example, the registration settlement device 10 displays information about real-time special sales (discount rate) on the product buttons on the registration screen (for example, "10%" in Fig. 20, and "(10%)" and "(15%)" in Fig. 29). The registration settlement device 10 also displays information about real-time special sales (discount rate, real-time special sale price which is the discounted unit price) in the unit price display area on the registration screen (for example, "(10% off) 360" in Fig. 21). The registration settlement device 10 also displays the message "Registering real-time special product" on the center left side of the registration screen (Figs. 21 to 23). The registered settlement device 10 also displays information about real-time special sales (discount rate, real-time special sale price which is the discounted unit price) in the purchased item display column on the center left of the settlement screen (for example, "(10% off)" and "@360" in Figure 25). The registered settlement device 10 may also display information about real-time special sales (for example, the total discount amount which is the sum of the discount amounts for each item) in the center right of the settlement screen (the area from the purchase quantity to the change). Note that although Figures 20 to 32 have been explained using the case of a discount as an example, the same applies to price reductions.

[0128] The registration settlement device 10 may display the unit price of each product on each product button. For products with a discount, the registration settlement device 10 may display the regular price and discount rate in addition to the discounted unit price (immediate special sale price). For example, if a 10% discount is set on side dish A (normally priced at 400 yen / 100g), the side dish A button may display "360 yen (normally 400 yen)," or "360 yen (10% discount)," or "360 yen (10% discount of normal 400 yen)." For products with a discount set, the registration settlement device 10 may display the normal price or discount amount in addition to the discounted unit price (instant sale price). For example, if a 30 yen discount is set on side dish A, the side dish A button may display "370 yen (normally 400 yen)," or "370 yen (30 yen discount)," or "370 yen (30 yen discount of normal 400 yen)."

[0129] The registration and settlement device 10 may display information about the real-time special sale on the customer display unit 104 in addition to the store clerk display unit 103. For example, when the registration screen of Figs. 21 to 23 is displayed on the store clerk display unit 103, the registration and settlement device 10 may display "(10% off) 360" as the unit price of side dish A on the customer display unit 104. The registration and settlement device 10 may also print information about the real-time special sale on receipts or labels issued by the printing unit 108.

[0130] Information about the instantaneous special sale may be displayed on an electronic shelf tag or on a signage. For example, when a 10% discount is set for prepared food A, the electronic shelf tag for prepared food A may display "(10% discount) 360 yen," or the signage may display an image of prepared food A along with a message saying "Presently, prepared food A is 10% off, 360 yen."

[0131] (Outputs instant sale prices and advance sale prices separately) Both advance sale prices and immediate sale prices can be set for a single product. The registered settlement device 10 may output information regarding advance sale (discount rate for advance sale, discount amount, discounted unit price, discount amount, discounted unit price, etc.) as well as information regarding advance sale (discount rate for advance sale, discount amount, discounted unit price, discount amount, discounted unit price, etc.). The registered settlement device 10 may output (display, print) information regarding advance sale and information regarding advance sale in a manner that allows them to be distinguished. For example, the discount rate may be displayed as "immediate 10%" and the latter as "pre-10%", and the discount amount may be displayed as "immediate 30 yen discount" and "pre-30 yen discount", respectively.

[0132] (Relationship between instant sale price and advance sale price) If the reserved sale price and the real-time sale price do not match (they collide), the registration settlement device 10 gives priority to the real-time sale price. For example, for a product (e.g., product A) for which a 15% discount is reserved for the five hours from 17:00 to closing (22:00), if a 20% discount is set as the real-time sale at 18:00 (and if the real-time sale is not reset or canceled after the setting), the product will be applied with a 15% discount for one hour from 17:00 to 18:00, and a 20% discount will be applied for four hours from 18:00 to closing. Also, for the above product A, if a 20% discount is set as the real-time sale at 16:00 (and if the real-time sale is not reset or canceled after the setting), the product will be applied with a 20% discount for six hours from 16:00 to closing. It is also possible to allow a 0% discount or 0 yen discount to be set as the real-time sale, and to invalidate the reserved sale price.

[0133] In the above two examples, if the instant sale setting is cancelled at 8 p.m., a 15% discount will be applied (the instant sale price will be changed to the advance sale price). In the above two examples, when the instant sale setting is cancelled at 8 p.m., a choice may be accepted as to whether or not to apply a 15% discount (whether to change from the instant sale price to the advance sale price or from the instant sale price to the regular price).

[0134] When setting an instant sale for a product that has already been changed to a pre-order special sale price (for example, when setting 20% ​​off as an instant sale price for the above product A at 6 p.m.), the registered settlement device 10 may display a message to the effect that the price has already been changed to the pre-order special sale price. When setting an instant sale for a product that is scheduled to be changed to a pre-order special sale price in the future before closing time (for example, when setting 20% ​​off as an instant sale price for the above product A at 4 p.m.), the registered settlement device 10 may display a message to the effect that the price is scheduled to be changed to a pre-order special sale price in the future before closing time.

[0135] As another control example, if the reservation special sale price and the real-time special sale price do not match, the registered settlement device 10 may prioritize the reservation special sale price. Also, if the reservation special sale price and the real-time special sale price do not match, the selection of which to prioritize may be accepted. Also, if the reservation special sale price and the real-time special sale price do not match, the registered settlement device 10 may select the one with the lower price. Also, there is no superiority or inferiority between the reservation special sale price and the real-time special sale price, and the one set later may be valid (overwritten). In other words, for products to which a reservation special sale price is applied, the reservation special sale price may be changed to the real-time special sale price based on the above-mentioned operation of the store clerk, and for products to which a real-time special sale price is applied, the real-time special sale price may be changed to the reservation special sale price based on a reservation.

[0136] (Settings other than sale) The registered settlement device 10 can instantly change the price of a product based on the operation of a store clerk (e.g., operation of the instant sale setting button, various buttons on the instant sale setting screen, or product buttons), but can also instantly change something other than the price based on the operation of the store clerk.

[0137] For example, a product information button may be placed on a registration screen or the like, a product information setting screen may be displayed in response to operation of the product information button, and the contents of the POP (text, numerical values, images, display mode, design, etc.) displayed on the display unit (customer display unit 104, store clerk display unit 103) of the registration settlement device 10, electronic shelf labels, signage, etc., may be instantly changed based on information input to the screen. Also, when a product is replaced with one that is sold as the same product but has a different place of origin or manufacturer, the place of origin or manufacturer may be instantly changed, and when a product is replaced with the same product but with a different expiration date (best before date), the expiration date (best before date) may be instantly changed. Similarly, guidance information, advertising information, etc. printed on receipts and labels may be instantly changed based on operation on the registration screen or the like.

[0138] The system 1 according to the embodiment has been described above, but the system 1 allows for more suitable sale and the like. For example, the store (on-site) can set a suitable sale price as appropriate, or cancel it as necessary. Also, the store (on-site) can change POP and the like as appropriate.

[0139] (Variations, etc.) Although each embodiment has been described above, the device configuration, data configuration, processing flow, display and output aspects, etc. can be appropriately changed as shown in, for example, the following (1) to (21). In addition, the following (1) to (21) may be appropriately combined with each other.

[0140] (1) In the above embodiment, when a product is specified, the example of switching from the product tab to the clerk tab is described (FIG. 5 → FIG. 6, FIG. 9 → FIG. 10, FIG. 20 → FIG. 21), but the timing of switching from the product tab to the clerk tab is not limited to this. For example, the product tab may be switched to the clerk tab when the tare weight is confirmed (FIG. 6 → FIG. 7, FIG. 10 → FIG. 11, FIG. 21 → FIG. 22) or when the purchase weight (sales price) is confirmed (FIG. 7 → FIG. 8, FIG. 11 → FIG. 12, FIG. 22 → FIG. 23).

[0141] (2) In the above embodiment, an example was described in which products to which a discount is applied are individually specified (FIGS. 18-19, 27-28), but the method of specifying products to which a discount is applied is not limited to this. Also, in the above embodiment, an example was described in which products to which a discount is to be cancelled are individually specified (FIGS. 30-31), but the method of specifying products to which a discount is to be cancelled is not limited to this.

[0142] For example, a global designation button may be provided under each of the product tabs (prepared dishes tab, leafy vegetable tab, root vegetable tab), and the global designation button under one product tab may be operated to accept the designation of all products under that product tab collectively as products to which a discount should be applied, or the global designation button under one product tab may be operated to accept the designation of all products under the all product tabs collectively as products to which a discount should be applied. Also, a global designation button may be provided in an area independent of the tabs (for example, the bottom), and the global designation button may be operated to accept the designation of all products under the all product tabs collectively as products to which a discount should be applied. The same applies to the designation of canceling the application of a discount.

[0143] The same applies to the method of designating the product to which the discount is to be applied and the method of designating the product to which the discount is to be cancelled.

[0144] Also, one or more groups each consisting of one or more products may be set in advance, separate from the grouping (groups) by tabs, and group designation buttons for designating each group may be provided at the bottom of the screen, and by operating one group designation button, designation of all products belonging to the group corresponding to the group designation button as products to which a discount (or discount) is to be applied may be accepted all at once. The same applies to designation for canceling the application of a discount (or discount).

[0145] (3) In the above embodiment, an example was described in which the discount rate (or discount amount) was specified by inputting the quantity (FIGS. 17 and 26). However, the discount rate (or discount amount) may also be specified by using a discount rate button (or discount amount button) corresponding to each discount rate (or discount amount).

[0146] (4) In the above embodiment, an example of specifying a discount rate (or discount amount) has been described (FIGS. 17 and 26), but an immediate special sale price may also be specified. For example, instead of setting a 10% discount for side dish A, which normally costs 400 yen / 100g, an immediate special sale price of 360 yen / 100g may be specified.

[0147] (5) In the above embodiment, an example was described in which, when setting an instant sale price, the discount rate or discount amount is determined, the target product is selected, and finally the execute button is operated to confirm the setting. However, the operation of the store clerk button (the customer's own store clerk button) may be required as a condition for confirming the setting of the instant sale price.

[0148] For example, the store clerk may operate the store clerk button before operating the execute button. For example, in the above embodiment, the order of input quantity → discount (price reduction) button → product selection → execute button (or the order of discount (price reduction) button → input quantity → product selection → execute button) has been described as the procedure for setting an instant sale price (FIGS. 17 to 19, 26 to 28), but the order may be input quantity → discount (price reduction) button → product selection → store clerk button → execute button (or the order of discount (price reduction) button → input quantity → product selection → store clerk button → execute button). Also, the store clerk may operate the store clerk button instead of the execute button. For example, in the above embodiment, the order may be input quantity → discount (price reduction) button → product selection → store clerk button (or the order of discount (price reduction) button → input quantity → product selection → store clerk button).

[0149] The code of the store clerk who set the real-time special sale price may be stored in the real-time special sale setting information (FIGS. 4(D) and 4(E)) as a history of which store clerk set the real-time special sale price.

[0150] It is also possible to set authority for setting instantaneous sale prices, and to permit authorized store clerks (when the clerk button of an authorized store clerk is operated) to set instantaneous sale prices, while restricting the setting of instantaneous sale prices for unauthorized store clerks (when the clerk button of an unauthorized store clerk is operated) (i.e., an operation error or setting error may be displayed).

[0151] Also, as a condition for finalizing the setting of the instant sale price, input of a password may be required instead of or in addition to the operation of the clerk button. When the clerk button and password are required, the setting of the instant sale price may be permitted only when the clerk button of an authorized clerk is operated and the correct password is entered, and when only a password is required, the setting of the instant sale price may be permitted only when the correct password is entered.

[0152] Similarly, the condition for confirming the release of the instant sale price may require the operation of a store clerk button or the input of a password.

[0153] (6) In the above embodiment, an example was described in which, when setting an instantaneous sale price, a store clerk operates the following order: input quantity → discount button → select product → execute button (or operates the following order: discount button → input quantity → select product → execute button) (Figures 17 to 19, Figures 26 to 28), but the discount button may also serve as the execute button.

[0154] FIG. 33 is a display example on the clerk display unit 103 of the registration and settlement device 10. For example, when a clerk operates the instant sale setting button on the registration screen (initial screen) of FIG. 5, the registration and settlement device 10 may display a registration screen as shown in FIG. 33 instead of popping up the instant sale setting screen as shown in FIG. 17. On the registration screen shown in FIG. 33, for example, when setting a 10% discount on side dishes A and E, the clerk operates the quantity "10" → discount button → side dish A button → side dish E button (or side dish E button → side dish A button) → discount button in this order. In other words, the second discount button also serves as the execution button. The clerk may operate the discount button → quantity "10" → side dish A button → side dish E button (or side dish E button → side dish A button) → discount button in this order. Also, when setting a 30 yen discount on side dish A, the store clerk operates the following order: quantity "30" → discount button → side dish A button → discount button. In other words, the second discount button also serves as the execution button. The store clerk may also operate the following order: quantity "30" → discount button → side dish A button → side dish E button (or side dish E button → side dish A button) → discount button.

[0155] In other words, the instant sale price may be set through a quantity input step in which the discount rate (discount amount) is input by operating the numeric keypad, a decision step in which the discount rate (discount amount) is determined by operating a price reduction operator (discount button, discount button), a product selection step in which one or more products are selected by operating a product operator (product button), and a discount (discount) setting step in which the discount rate (discount amount) determined by the decision step is set for the product selected in the product selection step by operating the price reduction operator.

[0156] To stop setting the instant sale price (to cancel (stop setting)), press the discount (price reduction) button a second time before pressing the product button. In other words, if no products are selected when pressing the discount (price reduction) button a second time, the setting will be canceled (stopped).

[0157] In addition, even if the clerk operates the instant sale release button on the registration screen (initial screen) of FIG. 5, the registration settlement device 10 may display a registration screen with a different message but the same buttons as FIG. 33. When the instant sale setting button is operated (when setting an instant sale price), the registration screen displays a message such as "Enter a number and operate "Discount" or "Price reduction" as shown in FIG. 33, but when the instant sale release button is operated (when canceling an instant sale price), the registration screen displays a message such as "Enter 0 and operate "Discount" or "Price reduction". When canceling an instant sale price by discount, the clerk operates the quantity "0" → discount button in that order. By the above operation, the registration settlement device 10 cancels the instant sale price for all products for which an instant sale price is set as a discount (sets it to the normal price). When canceling an instant sale price by discount, the clerk operates the quantity "0" → discount button in that order. By the above operation, the registration settlement device 10 cancels the instantaneous sale price (sets it to the normal price) for all products for which an instantaneous sale price has been set as a discount.

[0158] The registered settlement device 10 may cancel the instant sale price due to discount and the instant sale price due to price reduction all at once. For example, when a store clerk operates the quantity "0" and then the discount button (or the discount button), the registered settlement device 10 may cancel the instant sale price for all products for which an instant sale price is set, regardless of whether it is a discount or a price reduction. In a mode in which the instant sale price due to discount and the instant sale price due to price reduction are cancelled all at once, the discount button and the discount button may be one button (for example, a cancellation confirmation button).

[0159] To stop the release of the instant sale price (to cancel (cancel) the release), for example, operate the discount button (or price reduction button) before inputting the quantity. In other words, if the quantity "0" is not input when operating the discount button (or price reduction button), the release will be cancelled (cancel).

[0160] Also, the instant sale setting button and the instant sale cancellation button may be one button (for example, an instant sale button), and when the clerk operates the button (instant sale button), a registration screen with a different message but the same button as in FIG. 33 may be displayed. On the registration screen after the instant sale button is operated, a message such as "Enter the value to be set and operate "Discount" or "Price reduction". To cancel, enter 0 and operate "Discount" or "Price reduction". For example, when the clerk operates the instant sale button and operates the quantity "10" → side dish A button → discount button in the registration screen after the operation, the registration settlement device 10 sets an instant sale price of 10% off for side dish A. For example, when the clerk operates the instant sale button and operates the quantity "30" → side dish A button → discount button in the registration screen after the operation, the registration settlement device 10 sets an instant sale price of 30 yen off for side dish A. For example, if a store clerk operates the instant sale button and then operates the quantity "0" and then the discount button (or price reduction button) on the registration screen after the operation, the registration settlement device 10 will cancel both the instant sale price with discount and the instant sale price with discount together (it may also be possible to cancel either the instant sale price with discount or the instant special sale price with discount).

[0161] (7) In the above embodiment, when an instant sale price is set for one or more products, an example was described in which the instant sale price is maintained for products for which an instant sale price had already been set before the current setting and which was not specified in the current setting. However, the normal price may be restored for products for which an instant sale price had already been set before the current setting and which was not specified in the current setting (the instant sale price setting may be canceled). For example, in the example shown in Figures 26 to 28, the instant sale price (10% off price) is maintained for prepared food E, which was a product for which an instant sale price had already been set before the current setting and which was not specified in the current setting, but the normal price may be restored for prepared food E. If it is necessary to maintain the setting (10% off) for prepared food E, it is sufficient to reset the setting (10% off) for prepared food E again.

[0162] (8) The real-time sale setting information described in the above embodiment does not include information on the store clerk who is the setter (operator) (FIGS. 4(D)(E)), but the real-time sale setting information may include information on the store clerk who is the setter (e.g., the store clerk code). For example, when the store clerk "Kobayashi" operates the execute button on the registration screen of FIG. 19, the registration settlement device 10 generates real-time sale setting information including the product code of side dish A, the setting category "1 (discount)", the discount rate "10", and the store clerk code of the store clerk "Kobayashi", and real-time sale setting information including the product code of side dish E, the setting category "1 (discount)", the discount rate "10", and the store clerk code of the store clerk "Kobayashi", and stores them in the memory unit 102. The registration settlement device 10 may generate real-time sale setting information including the real-time sale unit price in addition to the above information, and store it in the memory unit 102.

[0163] (9) In the above embodiment, an example was described in which a product with an immediate sale price set and a product without an immediate sale price set are distinguished by the presence or absence of a discount rate (or discount amount) displayed on each product button. However, it is sufficient if a product with an immediate sale price set and a product without an immediate sale price set can be distinguished. For example, the product button of a product with an immediate sale price set may display characters such as "immediate sale price", "immediate special price", "immediate special", "immediate", etc., instead of or in addition to the discount rate (discount amount), or a predetermined mark (e.g., a star mark) may be displayed. Products with an immediate sale price set and products without an immediate sale price set may be distinguished by the display mode (display color, display size, display position, etc.) of the product button. The discount rate (discount amount), characters, and marks may be displayed on the product button (within the product button) or in the vicinity of the product button (e.g., above or below the product button). The clerk code or name of the clerk who set the immediate sale price for each product may be displayed on the product button (within the product button) or near the product button.

[0164] (10) In the above embodiment, an example was described in which the subtotal button (which also has a clerk code designation function) was displayed on the left center of the screen, but the display position of the subtotal button (which also has a clerk code designation function) does not have to be on the left center of the screen. For example, the subtotal button (which also has a clerk code designation function) may be displayed at the bottom of the screen.

[0165] (11) In the above embodiment, an example was described in which a subtotal button that also allows the specification of a clerk code (a subtotal button for each clerk) was displayed, but instead of the subtotal button that also allows the specification of a clerk code, a normal subtotal button (a subtotal button that does not also allow the specification of a clerk code; a subtotal button common to all clerks) may be displayed. When using a normal subtotal button, an operation to specify a clerk (clerk code) is accepted after the operation of the subtotal button is accepted, or an operation to specify a clerk (clerk code) is accepted after the operation of the subtotal button is accepted.

[0166] (12) In the above embodiment, an example in which a clerk code is used to identify one or more products designated by each customer has been described, but other information may be used as long as it is possible to identify one or more products designated by each customer. For example, a code different from the clerk code may be assigned to each clerk button. Also, instead of the clerk button, icons (such as "star," "moon," and "rocket," which are operable icons each assigned a code different from the clerk code) may be displayed and operated by the clerk in charge. A clerk in charge of a certain customer operates the same icon in the registration process (at the end) of each of the customer's one or more products and in the settlement process (at the start) of the customer. An icon to be operated by each clerk may be determined in advance. If an icon to be operated by each clerk is not determined in advance, an icon is displayed in a distinguishable manner as to whether it is currently in use or not so that two or more clerks after product registration and before the start of settlement do not operate the same icon, and a clerk in charge of registering one item of product uses an icon that is not currently in use. Note that instead of a button, a number, alphabet, etc. assigned to each clerk may be input.

[0167] (13) In the above embodiment, the real-time sale price by the operation (real-time sale setting operation) of one registered settlement device 10 is immediately applied to all registered settlement devices 10 on the LAN, but it does not have to be immediately applied to all registered settlement devices 10 on the LAN. The other registered settlement devices 10 (one or more registered settlement devices 10 other than the registered settlement device 10 where the real-time sale setting operation was performed) may periodically (for example, every few seconds) or at a predetermined time (a predetermined time set every minute) refer to the memory unit 102 of the registered settlement device 10 where the real-time sale setting operation was performed and apply (reflect) the real-time sale price to their own devices. In addition, the other registered settlement devices 10 may refer to the memory unit 102 of the registered settlement device 10 where the real-time sale setting operation was performed based on an explicit operation by a store clerk (operation of the price update button) and apply (reflect) the real-time sale price to their own devices.

[0168] (14) In the above embodiment, an example was described in which the sale price based on the setting was applied immediately after the setting operation (FIGS. 17 to 29), but the sale price based on the setting may be applied after some time has passed since the setting operation. In other words, in the above embodiment, an example was described in which the registered settlement device 10, as indicated by the name, accepts the setting of an instant sale price from a store clerk, but the registered settlement device 10 may accept the setting of a reservation special sale price from a store clerk instead of or in addition to the instant sale price.

[0169] The reservation special sale price accepted by the registered settlement device 10 may be applied on the day. In addition, the registered settlement device 10 may be able to specify the timing for applying the reservation special sale price as XX hours before closing, or XX minutes later (e.g., 10 minutes later) instead of or in addition to specifying XX hours before closing or XX:XX minutes.

[0170] Even if the price accepted by the registration settlement device 10 is a special sale price, it is set by the store (on-site), so there is a certain effect. Also, it is possible to announce (preview) the price by signage or the like.

[0171] (15) In the above embodiment, an example in which the price is lowered below the normal price has been described, but the price may be increased above the normal price. FIG. 34 is a display example (instant price change screen) on the clerk display unit 103 of the registered settlement device 10. For example, the registered settlement device 10 may display (for example, pop-up display) an instant price change screen as shown in FIG. 34 instead of the instant sale setting screen shown in FIG. 17 or FIG. 26. In the instant price change screen shown in FIG. 34, for example, when setting a 10% increase (high), the clerk operates the plus button → the number of items placed "10" → the change rate button (or the number of items placed "10" → the plus button → the change rate button) in that order. When setting a 10% decrease (low), the clerk operates the minus button → the number of items placed "10" → the change rate button (or the number of items placed "10" → the minus button → the change rate button) in that order. To set a 10 yen increase, the store clerk presses the plus button → the quantity "10" → the change amount button (or the quantity "10" → the plus button → the change amount button). To set a 10 yen decrease, the store clerk presses the minus button → the quantity "10" → the change amount button (or the quantity "10" → the minus button → the change amount button).

[0172] (16) In the above embodiment, an example was described in which multiple registered settlement devices 10 are installed in a store (FIG. 1), but the number of registered settlement devices 10 installed in a store may be one. In other words, in the above embodiment, an example was described in which the sales system 1 is equipped with multiple registered settlement devices 10 (FIG. 2), but the sales system 1 may be equipped with one registered settlement device 10. If there is one registered settlement device 10, the pre-subtotal information (FIG. 4(A)) does not need to include a device number. The same applies to the post-subtotal information (FIG. 4(B)).

[0173] (17) In the above embodiment, an example has been described in which the registration and settlement apparatus 10 includes the drawer 109 (FIG. 3). However, the registration and settlement apparatus 10 may include an automatic change dispenser instead of the drawer 109.

[0174] (18) In the above embodiment, an example was described in which the registered settlement device 10 settles the transaction with cash. However, the registered settlement device 10 may settle the transaction with non-cash (e.g., credit card, electronic money) instead of or in addition to cash.

[0175] (19) In the above embodiment, an example has been described in which the registration settlement device 10 has a product registration function and a settlement function, but the registration settlement device 10 does not have to have a settlement function. Hereinafter, if the registration settlement device 10 does not have a settlement function, the registration settlement device 10 without the settlement function will be referred to as the registration device 20 to avoid contradiction with the name.

[0176] The registration device 20 may be configured, for example, without the drawer 109 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 (for example, one or more pieces of pre-subtotal information, or post-subtotal information generated from the one or more pieces of pre-subtotal information) to the other device.

[0177] (20) In the above embodiment, an example was described in which the registered settlement device 10 includes the weighing unit 106. However, the registered settlement device 10 does not have to include the weighing unit 106. Hereinafter, a registered settlement device 10 that does not include the weighing unit 106 will be referred to as a registered settlement device 30. Also, a registered settlement device 10 that does not include a weighing unit 106 or a settlement function will be referred to as a registration device 40. The registered settlement device 30 (as well as the registration device 40) may be a device that reads a barcode attached to a product and registers the product.

[0178] (21) In the above embodiment, some or all of the functions (input / output, memory, processing (including judgment)) of the registered settlement device 10 may be realized in a device other than the device described as the entity that executes the function.

[0179] For example, instead of storing information (pre-subtotal information, post-subtotal information, etc.) in the memory unit 102 of its own device, the registered settlement device 10 may store the information in another registered settlement device 10 (the representative (parent) registered settlement device 10), or may store the information in a device different from the registered settlement device 10 (for example, a store controller, management device, external server). In other words, each registered settlement device 10 only needs to be able to refer to information generated by its own registered settlement device 10 or another registered settlement device 10. The same applies to the registered settlement device 20, the registered settlement device 30, and the registered settlement device 40.

[0180] Also, instead of the registration settlement device 10, another device (for example, a cloud server) may calculate the total amount from the unit price and the purchase weight. Also, instead of the registration settlement device 10, another device (for example, a cloud server) may calculate the real-time special sale price and the advance sale price. The registration settlement device 10 may function as a so-called thin client specialized for input / output interfaces, etc. For example, the cloud server may execute a program for controlling the operation of the registration settlement device 10, and the registration settlement device 10 may display screens (screens of Figures 5 to 34) generated by the cloud server using a browsing function. The same applies to the registration device 20, the registration settlement device 30, and the registration device 40.

[0181] <Overview of the embodiment> [Technical field] The present invention relates to a registration device and a setting method. [Background technology] 2. Description of the Related Art A weighing pricing system is known that sets a sale period during which a sale discount is applied (see, for example, Patent Document 1). [Prior art document] [Patent documents] [Patent Document 1] JP 2008-33685 A [Summary of the invention] [Problem to be solved by the invention] However, there is room for improvement in terms of sales. The present invention has been made in view of the above circumstances, and has an object to provide a technique that enables sales to be carried out more appropriately. [Means for solving the problem]

[0182] (1) A registration device (e.g., registration settlement device 10, registration device 20, registration settlement device 30, registration device 40) comprising a registration means for registering a product, a sale setting receiving means for receiving a sale setting which is a setting related to a sale of the product, and a price changing means for changing the price of the product to a sale price based on the sale setting received by the sale setting receiving means, wherein the sale setting is a setting related to a sale of the product that is immediately applied and is valid until the end of the business day, and the price changing means, when the sale setting is received by the sale setting receiving means, immediately changes the price of the product to the sale price based on the sale setting. The registration device of (1) allows for more convenient sale. For example, a sale price can be set according to the situation (sales, number of customers, etc.) at the location (site) where the registration device is installed. Also, for example, measures (selling at the sale price) can be taken promptly by being aware of (predicting) the sales, etc. of the business day in question.

[0183] (2) The registration device described in (1) is characterized in that it is provided with a sale cancellation acceptance means for accepting the cancellation of the sale setting, and when the sale cancellation acceptance means accepts the cancellation of the sale setting, the price change means immediately changes the price of the product from the sale price to the regular price. The registration device of (2) allows for more efficient sale. For example, if it is determined that the sale price needs to be reviewed, measures can be taken immediately (sale at normal price).

[0184] (3) A registration device as described in (1), further comprising a display means for displaying a registration screen on which a product button is arranged for each product, the registration means being capable of registering a product specified by the product button, and the sale setting acceptance means accepting the setting of a product subject to sale as the sale setting by the product button. The registration device of (3) allows a sale to be carried out more conveniently. For example, the sale price can be set easily.

[0185] (4) The registration device described in (3) is characterized in that the display means distinguishably displays product buttons for products whose prices have been changed to special sale prices by the price change means from product buttons for products whose prices have not been changed to special sale prices by the price change means. The registration device of (4) allows for more efficient sales. Since it is clear at a glance whether or not a product has a special sale price, the store clerk can explain to the customer that the product he or she has purchased has a special sale price, or can introduce the customer to other products that also have special sale prices.

[0186] (5) The registration device described in (3) or (4) is characterized in that the display means is capable of displaying a plurality of numeric buttons into which a quantity can be input, and the sale setting acceptance means accepts the setting of a discount rate or discount amount as the sale setting using the numeric buttons. The registration device of (5) allows for more convenient sale. Special sale prices can be set easily and precisely (for example, in 1% or 1 yen increments). This allows for quick presentation / representation of a more attractive price than that of nearby competing stores.

[0187] (6) A setting method for setting a special sale price that is immediately applied to a product and is valid until the end of the business day using a registration device, the setting method including a first step of inputting a discount rate or discount amount, a second step of finalizing the discount rate or discount amount input in the first step, a third step of designating a product to which the discount or discount is to be applied, and a fourth step of setting the discount rate or discount amount finalized in the second step to the product designated in the third step. According to the setting device of (6), as in (1) above, the special sale can be carried out more efficiently.

[0188] In addition, a program for realizing the functions of each device described above (for example, the registration and settlement device 10, the registration device 20, the registration and settlement device 30, the registration device 40, etc.) may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed to perform processing of each device. Here, "reading a program recorded on a recording medium into a computer system and executing it" includes installing the program into a computer system. The "computer system" here includes hardware such as an OS and peripheral devices. In addition, the "computer system" may include multiple computer devices connected via a network including the Internet, a WAN, a LAN, a dedicated line, and other communication lines. In addition, the "computer-readable recording medium" refers to a portable medium such as a flexible disk, an optical magnetic disk, a ROM, a CD-ROM, and a storage device such as a hard disk built into a computer system. In this way, the recording medium storing the program may be a non-transient recording medium such as a CD-ROM. In addition, the recording medium also includes a recording medium provided inside or outside the computer system that can be accessed from a distribution server in order to distribute 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 format executable by a terminal device. That is, the format in which the program is stored in the distribution server does not matter as long as the program can be downloaded from the distribution server and installed in a form executable by the terminal device. The program may be divided into multiple parts, each of which may be downloaded at a different time and then combined on the terminal device, or each of the divided programs may be distributed by a different distribution server. Furthermore, the term "computer-readable recording medium" includes a storage medium that holds a program for a certain period of time, such as a volatile memory (RAM) inside a computer system that is a server or client when a program is transmitted over a network. The program may also be one that realizes part of the above-mentioned functions.Furthermore, the above-mentioned functions may be realized in combination with a program already recorded in the computer system, that is, a so-called differential file (differential program).
