[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 at the registration and settlement device 10. After the weight stabilizes, the registration and settlement device 10 displays (to the store clerk and customer) the weight of the purchased items (purchase weight, net weight) and the selling price of the purchased items. The registration and settlement device 10 calculates the selling price of the purchased items from the unit price of the purchased items and the weight of the purchased items.

[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] (Membership card (point card)) The registered settlement device 10 can read the membership card during a transaction. Specifically, the registered settlement device 10 can read the membership card at any timing before the operation of the DEPOSIT / CURRENT button on the settlement screen in step 6 (settlement) above. For example, in the case of a transaction in which a customer (e.g., customer A) purchases product A (1st item) and product (2nd item), the registered settlement device 10 can read the membership card of customer A during any of the following periods 1 to 10. (Period 1) Before operating the product button for Product A (before step 2 for item 1) (Period 2) After operating the product button for product A, before setting the tare weight of the tare container that will hold product A (between process 2 of item 1 and process 3 of item 1) (Period 3) After the tare weight of the container that holds product A is set, but before product A is weighed (between process 3 of item 1 and process 4 of item 1) (Period 4) After weighing product A, before entering the clerk code to complete the registration of product A (between step 4 of item 1 and step 5 of item 1) (Period 5) After entering the clerk code to complete the registration of product A, but before operating the product button for product B (between step 5 of item 1 and step 2 of item 2) (Period 6) After operating the product button for product B, before setting the tare weight of the tare container that will hold product B (between process 2 of item 2 and process 3 of item 2) (Period 7) After the tare weight of the container that holds product B is set, but before product B is weighed (between process 3 of item 2 and process 4 of item 2) (Period 8) After weighing product B, before entering the clerk code to complete the registration of product B (between step 4 of item 2 and step 5 of item 2) (Period 9) After entering the clerk code to complete the registration of product B, before pressing the subtotal button (which also specifies the clerk code) (between step 5 and step 6 of the second item) (Period 10) After pressing the Subtotal button, before pressing the Deposit / Current button (until midway through step 6)

[0033] When multiple membership cards are read in one transaction, the registration and settlement device 10 can read two or more membership cards at the same time, or can read each membership card at a different time. For example, if the above customer A has three membership cards, two of them can be read in period 1 and the remaining one can be read in period 5.

[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] By executing a program, CPU 101 executes various processes (e.g., display control process for various screens, calculation process for total amount, etc.) 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 (e.g., the information shown in FIG. 4, screen information, message information, print format information, and identification information of its 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 58) 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. When the CPU 101 acquires the weighed value from the weighing unit 106, it 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 is an example of various types of information. FIG. 4(A) is 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 memory 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, membership card information, and processing classification. The sales price determination data includes a product code that identifies the purchased product, the unit price of the purchased product, the purchase weight, and the sales price.

[0047] (Membership card information) The registered settlement device 10 reads the membership card information from the membership card. The registered settlement device 10 reads at least a part of the information held by the membership card. In other words, the membership card information is information that the registered settlement device 10 reads from the membership card (all or a part of the information held by the membership card). Furthermore, the registered settlement device 10 may acquire (receive) information about the membership card (point information, customer information) from an external source (for example, a server that manages point information such as the number of owned points (number of usable points), point expiration date, and customer information such as customer name) based on the information read from the membership card. Information that the registered settlement device 10 acquires from an external source based on the information it reads from the membership card may be referred to as the membership card information. In other words, the membership card information is information based on the membership card (information obtained by reading the membership card).

[0048] The information that the registered settlement device 10 reads from the membership card includes customer identification information (information that can identify each customer among those who hold the membership card). In other words, the registered settlement device 10 reads at least the customer identification information from the membership card. The information that the registered settlement device 10 reads from the membership card may further include card type information (card classification information) indicating the type of card (for example, card C1, card C2, card C3, or card C4, which will be described later). In other words, the registered settlement device 10 may read at least the card type information and the customer identification information from the membership card.

[0049] For example, in the case of a membership card that holds point information, the registration settlement device 10 reads, for example, customer identification information and point information from the membership card (it may also read customer identification information, card type information, and point information). In other words, the membership card information of a membership card that holds point information (membership card information based on the membership card) is information read from the membership card (for example, customer identification information, (card type information), point information). The registration settlement device 10 may acquire information (such as customer name) from outside based on the customer identification information acquired from the membership card, and if information is acquired from outside, the information acquired from outside may also be referred to as membership card information.

[0050] Furthermore, in the case of a membership card that does not hold point information, the registered settlement device 10, for example, reads customer identification information from the membership card (it may also read customer identification information and card type information). In other words, the membership card information of a membership card that does not hold point information is information read from the membership card (for example, customer identification information, (card type information)). The registered settlement device 10 may acquire information (point information, customer name, etc.) from outside based on the customer identification information acquired from the membership card, and when information is acquired from outside, the information acquired from outside may also be referred to as membership card information.

[0051] The pre-subtotal information in Figure 4 (A) has a membership card information item, but if a membership card is not read when registering the purchased item, there is no membership card information (the item does not have to be present). If multiple membership cards are read when registering the purchased item, the membership card information for each membership card is stored. The processing category is information that indicates whether the subtotal button has been operated or whether settlement has been completed. A processing category value of "0" is before settlement has begun (initial value). A processing category value of "1" is when settlement is in progress. A processing category value of "2" is when settlement has been completed.

[0052] 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)".

[0053] 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 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 products are product 1, product 2, and product 3. Product 1 is information about one purchased product. Product 1 includes the device number of the registered settlement device 10 that registered the one purchased product, the membership card information of one or more membership cards that were read when the one purchased product was registered, and the sales price confirmation data for the one purchased product. The same applies to products 2, ..., product N.

[0054] The post-subtotal information shown in FIG. 4(C) is post-subtotal information in which membership card information has been added to the end of the post-subtotal information shown in FIG. 4(B). The membership card information at the end of the post-subtotal information shown in FIG. 4(C) is membership card information of one or more membership cards read after the subtotal button is operated. As described above, the registered settlement device 10 can read a membership card after the subtotal button for a product is operated (specifically, after the subtotal button is operated and before the deposit / present button is operated) (e.g., period 10). When one or more membership cards are read after the subtotal button is operated, the registered settlement device 10 adds the membership card information of one or more membership cards read after the subtotal button is operated to the end of the post-subtotal information (FIG. 4(B)) generated and stored based on the operation of the subtotal button, as shown in FIG. 4(C).

[0055] Note that the post-subtotal information (Figures 4(B) and 4(C)) makes it possible to identify which product was being registered when the membership card was read; however, since the membership card information is processed as the post-subtotal information as a whole, it has the same effect regardless of which product was being registered when the membership card was read.

[0056] In relation to the above, because the pre-subtotal information (FIG. 4(A)) including the membership card information can be referenced as log information capable of identifying the membership card read when registering each product (because the processing category value is updated as the processing progresses but is not erased), the post-subtotal information does not need to be capable of identifying which product the membership card was read when registering. For example, it may be post-subtotal information as shown in FIG. 4(D). The membership card information at the end of the post-subtotal information shown in FIG. 4(D) is the membership card information of one or more membership cards read when registering purchased products, product 1, product 2, ... product N, and the membership card information of one or more membership cards read after operating the subtotal button.

[0057] Note that since the pre-subtotal information (Fig. 4(A)), which includes the machine number, can be referenced as log information capable of identifying the machine in which each product was registered (the processing category value is updated as processing progresses but is not erased), the post-subtotal information (Figs. 4(B), 4(C), and 4(D)) 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.

[0058] Furthermore, the registered settlement device 10 may generate post-subtotal information (FIGS. 4(B), 4(C), 4(D)) from one or more pieces of pre-subtotal information (FIG. 4(A)) and execute settlement processing based on the generated post-subtotal information, 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 (FIGS. 4(B), 4(C), 4(D)).

[0059] FIG. 4(E) is an example of a product master (basic product information). The product master shown in FIG. 4(E) includes a product code, a product name, a unit 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 product. For a product in the measurement category "1 (fixed price)", the unit price is the selling price of 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) the product master from another device (for example, a store controller (not shown), an external server (not shown)) and store it in the memory unit 102.

[0060] (Display on the store clerk display unit 103) 5 to 44 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.

[0061] At the start of the explanation of FIG. 5, there is no pre-subtotal information for process category "0 (before settlement begins)" or pre-subtotal information for process category "1 (during settlement)". The existence of pre-subtotal information for process category "0 (before settlement begins)" means that there is a store clerk serving a customer in a state where settlement has been started after product registration but before settlement has started (a customer who has registered a product but before settlement has started). The existence of pre-subtotal information for process category "1 (during settlement)" means that there is a store clerk serving a customer in a state where settlement has been started but before settlement has been completed (a customer who has started settlement but before settlement has been completed). In other words, at the start of the explanation of FIG. 5, there is no store clerk serving a customer in a state where settlement has been started after product registration but before settlement has started (a customer who has registered a product but before settlement has started) or a store clerk serving a customer in a state where settlement has been started but before settlement has been completed (a customer who has started settlement but before settlement has been completed).

[0062] At the top of the registration screen shown in FIG. 5 (as well as other registration screens), a display area is provided that displays the tare weight, product name, purchase weight, unit price, sales price, total number of items, total amount (price), etc. At the center right of the registration screen shown in FIG. 5 (as well as other registration screens), multiple tabs (prepared food tab, leafy vegetable tab, root vegetable tab, 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) are displayed. Note that the tabs are switched according to the operation of the clerk, but the registration and settlement device 10 may automatically switch tabs according to the progress of the process. At the bottom of the registration screen shown in FIG. 5 (as well as other registration screens and settlement screens), various buttons (membership card cancellation button, etc.) are displayed. The membership card cancellation button is a button that accepts the operation to cancel the membership card (the operation to erase the membership card information).

[0063] 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 tare button, etc.) are valid buttons (operable buttons), while buttons shown in dashed frames (e.g., the membership card cancellation operation, 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. Furthermore, an invalid button may display an error message after operation.

[0064] (If you purchase one item) Figures 6 to 12 are display examples when one product is purchased. The screen transitions are as follows: Figure 6 → Figure 7 → Figure 8 → Figure 9 → Figure 10 → Figure 11 → Figure 12. It is assumed that when the registration and settlement device 10 is displaying the registration screen (initial screen) of Figure 5, a customer (customer c) instructs to purchase 150 g of side dish A (unit price is 400 yen / 100 g), and the order is accepted by the store clerk "Suzuki."

[0065] When the sales clerk "Suzuki" operates the prepared food A button on the registration screen (initial 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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 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 (Fig. 10) when the subtotal button for store clerk Suzuki is operated on the registration screen in Fig. 9.

[0071] When the clerk "Suzuki" operates the subtotal button for clerk Suzuki on the registration screen in Fig. 9, the registration settlement device 10 displays a settlement screen (subtotal screen) as shown in Fig. 10. 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, post-subtotal information) based on one piece 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 displays the settlement screen as shown in Fig. 10. 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 one piece of pre-subtotal information) from "0 (before settlement begins)" to "1 (during settlement)".

[0072] The upper part of the settlement screen shown in FIG. 10 (as well as other settlement screens) is provided with a display area for displaying the tare weight and purchase weight. The registered settlement device 10 can display the tare weight and 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 of FIG. 10 (the settlement screen of customer c) displayed (for example, when the sales clerk "Suzuki" in charge moves to another place while the settlement screen of FIG. 10 is displayed and does not return for a long time), the sales clerk in charge of another customer operates the tare button on the settlement screen to weigh a tare (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 tare 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, while maintaining the settlement screen during settlement for one customer, it is possible to prepare the purchased goods of another customer.

[0073] When the clerk "Suzuki" operates the deposit / present button on the settlement screen of FIG. 10, the registration settlement device 10 pops up a small screen (a deposit amount input screen) as shown in FIG.

[0074] When the clerk "Suzuki" inputs 700 yen as the deposit amount from the customer c on the small screen in FIG. 11 and presses the Confirm button, the registration settlement device 10 erases the small screen and displays the settlement screen (settlement completion screen) as shown in FIG. 12. The settlement screen in FIG. 12 (similar to the settlement screens in FIG. 19, FIG. 25, and FIG. 40) displays a message "You can register the next customer" as guidance information for the clerk, indicating that the next customer (the product purchased by the next customer) can be registered. When a predetermined time (for example, 5 seconds) has elapsed, the registration settlement device 10 displays the registration screen (initial screen) shown in FIG. 5. In addition, the registration settlement device 10 updates the processing category of the pre-subtotal information of the clerk (pre-subtotal information including the clerk code of the clerk "Suzuki") from "1 (settlement in progress)" to "2 (settlement completed)" based on the operation of the Confirm button.

[0075] (If you purchase two items) 6 to 9 and 13 to 19 are display examples when two products are purchased. The transition is as follows: Fig. 6 → Fig. 7 → Fig. 8 → Fig. 9 → Fig. 13 → Fig. 14 → Fig. 15 → Fig. 16 → Fig. 17 → Fig. 18 → Fig. 19, but as Fig. 6 → Fig. 7 → Fig. 8 → Fig. 9 have already been explained, their explanation will be omitted.

[0076] It is assumed that, when the registration and settlement device 10 is displaying the registration screen of Figure 9 (the registration screen after the sales clerk "Suzuki" operates the Suzuki button for customer c's first item, side dish A), customer c instructs the sales clerk "Suzuki" to purchase 500 yen worth of side dish C (unit price 380 yen / 100g) as the second item (desired purchase amount is 500 yen), and that this is accepted by the sales clerk "Suzuki".

[0077] 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 such as that shown in Fig. 13. 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.

[0078] When the clerk "Suzuki" sets the tare weight on the registration screen of Figure 13 (for example, when he operates the tare button and weighs the tare (empty) (the weighing value is 8g)), the registration settlement device 10 displays a registration screen such as that shown in Figure 14.

[0079] When the store clerk "Suzuki" weighs side dish C in a tare (8 g) on ​​the registration screen of Fig. 14 (the measured value is 138 g), the registration and settlement device 10 displays a registration screen such as that shown in Fig. 15. 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. 15, operation of the clerk button is enabled.

[0080] When the store clerk "Suzuki" operates his / her own Suzuki button on the registration screen in Fig. 15, the registration settlement device 10 displays a registration screen as shown in Fig. 16. 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 side dish tab. The registration settlement device 10 also generates pre-subtotal information for side dish C based on the operation of the Suzuki button and stores it in the memory unit 102. Because the registration of side dish C has been completed (because payment can now be proceeded to), operation of the subtotal button for store clerk Suzuki is enabled.

[0081] 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. 16. 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. 16.

[0082] 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. 16. 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. 16. The registration and settlement device 10 displays the settlement screen (Fig. 17) when the subtotal button for store clerk Suzuki is operated on the registration screen in Fig. 16.

[0083] When the clerk "Suzuki" operates the subtotal button for clerk Suzuki on the registration screen of Fig. 16, the registration settlement device 10 displays a settlement screen (subtotal screen) as shown in Fig. 17. In other words, because the clerk code of 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 of 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 of Fig. 15), and displays the settlement screen as shown in Fig. 17. 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 the clerk (the above two pieces of pre-subtotal information) from "0 (before settlement begins)" to "1 (during settlement)".

[0084] When the clerk "Suzuki" operates the deposit / present button on the settlement screen of FIG. 17, the registration settlement apparatus 10 pops up a small screen (deposit amount input screen) as shown in FIG.

[0085] When the clerk "Suzuki" in charge inputs 1,181 (yen) as the amount of the deposit received from customer c on the small screen in FIG. 18 and presses the Confirm button, the registration settlement device 10 clears the small screen and displays the settlement screen (settling completion screen) as shown in FIG. 19. 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 of the clerk (pre-subtotal information including the clerk code of the clerk "Suzuki" in charge) from "1 (settling in progress)" to "2 (settling completed)."

[0086] (If there is an interrupt) Figures 6 to 9 and 20 to 28 are examples of displays when an interrupt occurs. The transitions are as follows: Figure 6 → Figure 7 → Figure 8 → Figure 9 → Figure 20 → Figure 21 → Figure 22 → Figure 23 → Figure 24 → Figure 25 → Figure 26 → Figure 5 → Figure 27 → Figure 28, but as Figure 6 → Figure 7 → Figure 8 → Figure 9 have already been explained, their explanation will be omitted.

[0087] It is assumed that while the registration and settlement device 10 is displaying the registration screen of Figure 9 (the registration screen after the sales clerk "Suzuki" operates the Suzuki button for the first item of side dish A for customer c), another customer (customer d) instructs the sales clerk "Tanaka" to purchase 200 g of side dish D (unit price 360 ​​yen / 100 g), and this is accepted by the sales clerk "Tanaka."

[0088] When the clerk "Tanaka" operates the prepared dish D button on the registration screen in Fig. 9, the registration and settlement device 10 displays a registration screen as shown in Fig. 20. 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 D has begun (because it is no longer possible to proceed to payment), operation of the subtotal button for clerk Suzuki is invalid.

[0089] When the clerk in charge, "Tanaka", sets the tare weight on the registration screen of Figure 20 (for example, when he operates the tare button and weighs the tare (empty) (the weighing value is 12 g)), the registration settlement device 10 displays a registration screen such as that shown in Figure 21.

[0090] When the store clerk "Tanaka" in charge weighs side dish D in a tare (12 g) on ​​the registration screen of Fig. 21 (the measured value is 212 g), the registration settlement device 10 displays a registration screen as shown in Fig. 22. After the weight stabilizes, the registration settlement device 10 calculates the selling price (720 yen) from the unit price of side dish D (360 yen / 100 g) and the purchase weight (200 g). Because the selling price has been confirmed on the registration screen of Fig. 22, operation of the clerk button is enabled.

[0091] When the responsible store clerk "Tanaka" operates his / her own Tanaka button on the registration screen of FIG. 22, the registration settlement device 10 displays a registration screen as shown in FIG. 23. 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 D 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. 23. The subtotal button for clerk Tanaka displays "Tanaka" to indicate that it is for clerk Tanaka.

[0092] If customer d does not purchase any products other than side dish D (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. 23. If customer d purchases products other than side dish D, the sales clerk "Tanaka" operates the product button for the next product to be purchased on the registration screen in Fig. 23.

[0093] The registration and settlement device 10 may erase the total information (1 item, 720 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. 23. The registration and settlement device 10 erases the total information if the product button is operated on the registration screen in Fig. 23 before a predetermined time has elapsed since the start of displaying the registration screen in Fig. 23. The registration and settlement device 10 also displays the settlement screen (Fig. 24) when the subtotal button for clerk Tanaka is operated on the registration screen in Fig. 23.

[0094] When the clerk "Tanaka" in charge operates the subtotal button for clerk Tanaka on the registration screen in Fig. 23, the registration settlement device 10 displays a settlement screen (subtotal screen) as shown in Fig. 24. In other words, because the clerk code for clerk "Tanaka" was entered by operating the subtotal button for clerk Tanaka, the registration settlement device 10 generates (for example, post-subtotal information) and displays the settlement screen as shown in Fig. 24 based on one piece of pre-subtotal information (pre-subtotal information for side dish D generated and stored based on operation of the Tanaka button on the registration screen in Fig. 22). In addition, based on operation of the subtotal button for clerk Tanaka, the registration settlement device 10 updates the processing category of the pre-subtotal information for that clerk (the above one piece of pre-subtotal information) from "0 (before settlement begins)" to "1 (during settlement)".

[0095] When the clerk "Tanaka" operates the deposit / present button on the settlement screen in FIG. 24, the registration settlement device 10 pops up a small screen (deposit amount input screen) (not shown). When the clerk "Tanaka" operates the deposit / present button on the small screen, 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. 5. Based on the operation of the confirm button, the registration settlement device 10 also updates the processing category of the pre-subtotal information of the clerk (pre-subtotal information including the clerk code of the clerk "Tanaka") from "1 (settlement in progress)" to "2 (settlement completed)".

[0096] In addition, while the salesclerk "Tanaka" was processing the order for customer d (registering side dish D and paying), customer c instructed the salesclerk "Suzuki" to purchase side dish C (unit price 380 yen / 100g) for 500 yen (desired purchase amount is 500 yen) as the second item. Also, customer c will purchase a total of two items (side dish A and side dish C).

[0097] When the store clerk "Suzuki" operates the side dish C button on the registration screen (initial screen) of Fig. 5, which is displayed following the settlement screen (settlement completion screen) shown in Fig. 25, the registration settlement device 10 displays a registration screen as shown in Fig. 26. The "1" displayed on the Suzuki button indicates that one piece of pre-subtotal information (pre-subtotal information for the first item of side dish A) for customer c, who is handled by the store clerk "Suzuki", is stored.

[0098] When the store clerk "Suzuki" sets the tare weight (8 g) on ​​the registration screen in Fig. 26 and then puts side dish C into the tare weight (8 g) and weighs it (the measured value is 138 g), the registration and settlement device 10 displays the registration screen shown in Fig. 27. 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).

[0099] When the store clerk "Suzuki" operates his / her own Suzuki button on the registration screen of Fig. 27, the registration settlement device 10 displays a registration screen as shown in Fig. 28. The registration settlement device 10 also generates pre-subtotal information for side dish C based on the operation of the Suzuki button and stores it in the memory unit 102. Fig. 28 and subsequent figures are the same as Figs. 17 to 19, so the explanation will be omitted.

[0100] (When scanning a membership card) 29 to 40 are examples of displays relating to reading of a membership card. Following the registration screen (initial screen) of Fig. 5, as shown in Figs. 6 to 9 and 13 to 19, the store clerk "Suzuki" in charge of customer c registers two products (prepared dish A and prepared dish C) for customer c and settles the bill. Also, customer c has four types of membership cards (card C1, card C2, card C3, card C4) that can be used at the store.

[0101] For example, when the registration settlement device 10 reads the card C1 of the customer c on the registration screen (initial screen) of Fig. 5, the registration settlement device 10 displays a registration screen as shown in Fig. 29. For example, the registration settlement device 10 may read the card C1 by scanning the barcode printed on the card C1 with the scanner unit 105.

[0102] On the registration screen in Fig. 29, the operation of the clerk button on the clerk tab is enabled. In other words, because the registration settlement device 10 has read the membership card (card C1), in order to link the membership card (card C1) with the clerk (the clerk in charge, "Suzuki") (in other words, to include the membership card information in the pre-subtotal information), it switches from the side dishes tab to the clerk tab and enables the operation of the clerk button, even before the selection of a product. Also, on the registration screen in Fig. 29 (as well as the registration screen in Fig. 34), a message "Please select a clerk" is displayed as guidance information for the clerk, indicating that a clerk needs to be selected (enter a clerk code by operating the clerk button).

[0103] When the sales clerk "Suzuki" operates his / her own Suzuki button on the registration screen of Fig. 29, the registration settlement device 10 displays a registration screen as shown in Fig. 30. The registration settlement device 10 does not display the next screen, the registration screen of Fig. 30, until one of the sales clerk buttons is operated on the registration screen of Fig. 29. In other words, the registration settlement device 10 restricts the progress of the next process (for example, in the scene of Fig. 29, the process of accepting product selection on the registration screen of Fig. 30) until the sales clerk code is acquired.

[0104] In the registration screen of FIG. 30, the operation of the product button of the side dish tab is enabled. In other words, the registration settlement device 10 has completed the linking of the membership card (card C1) and the clerk (the clerk in charge "Suzuki") by the operation of the clerk button, and because the selection of the product has not yet been made (to accept the selection of the product), it switches from the clerk tab to the side dish tab and enables the operation of each side dish button. In addition, in the registration screen of FIG. 30, "C1" is displayed in the upper right corner to indicate that the card C1 has been read (the type of the read membership card is C1). "C1" is the card type information read from the card C1, or information based on the card type information. In other words, the registration settlement device 10 displays the type of the read membership card of the customer (customer c) in the upper right corner. In addition, in the registration screen of FIG. 30, the operation of the cancel membership card button is enabled.

[0105] When the store clerk "Suzuki" operates the prepared food A button on the registration screen of FIG. 30 and then reads the card C2 of customer c, the registration and settlement device 10 displays a registration screen as shown in FIG.

[0106] In the registration screen of FIG. 31, the operation of the clerk button in the clerk tab is disabled. In other words, the registration settlement device 10 reads the membership card (card C2) after switching from the side dish tab to the clerk tab by operating the side dish A button, but since the link between the membership card (card C1) and the clerk (the clerk in charge, "Suzuki") has already been completed in the registration of the product (side dish A) (because card C2 is linked to the clerk in charge, "Suzuki", even without any operation), and since the sales price of the product (side dish A) has not been determined, the operation of the clerk button remains disabled. Also, in the registration screen of FIG. 31, in addition to "C1" indicating that card C1 has been read, "C2" indicating that card C2 has been read (the type of the read membership card is C2) is displayed on the upper right side. "C2" is the card type information read from card C2, or information based on the card type information. The circle 2 on the upper right of the Suzuki button indicates that two membership cards (Card C1, Card C2) have been read for the customer (Customer A) who is handled by the sales clerk "Suzuki." The same is true for the registration screens in Figures 32 and 34.

[0107] When the store clerk "Suzuki" sets the tare weight (10 g) of the tare to hold side dish A on the registration screen of Figure 31, and then puts side dish A into the tare (10 g) and weighs it (the measured weight is 160 g), the registration settlement device 10 displays a registration screen such as that shown in Figure 32.

[0108] In the registration screen of Fig. 32, the operation of the clerk button in the clerk tab is enabled. In other words, the registration and settlement device 10 enables the operation of the clerk button because the sales price of the product (prepared dish A) has been confirmed.

[0109] When the sales clerk "Suzuki" operates his / her own Suzuki button on the registration screen of FIG. 32, the registration and settlement apparatus 10 displays a registration screen as shown in FIG.

[0110] In the registration screen of Fig. 33, "C1" and "C2" on the upper right side have been erased. In other words, the registration settlement device 10 has erased "C1" and "C2" on the upper right side because the relationship between the registration settlement device 10 and the responsible store clerk "Suzuki" has been temporarily severed (because another store clerk can now interrupt) when the registration of the product (prepared dish A) is completed.

[0111] Note that the operation of the cancel membership card button remains valid on the registration screen in Fig. 33. In other words, although the relationship between the registration settlement device 10 and the responsible store clerk "Suzuki" is temporarily severed when the registration of the product (prepared dish A) is completed, the read membership card (card C1, card C2) of customer c can be identified by specifying the responsible store clerk "Suzuki" after operating the cancel membership card button (Figs. 41 to 44), so the registration settlement device 10 keeps the operation of the cancel membership card button valid even when the registration of the product is completed. More specifically, the registration settlement device 10 enables the operation of the membership card cancellation button when the membership card is read when registering the product in question but the registration of the product is not complete (when pre-subtotal information for processing category "0 (before settlement begins)" including membership card information is generated upon completion of registration of the product), or when pre-subtotal information for processing category "0 (before settlement begins)" including membership card information exists (pre-subtotal information for the customer (the clerk in charge) or pre-subtotal information for another customer (another clerk in charge)).

[0112] In addition, the registered settlement device 10 generates pre-subtotal information for side dish A based on the operation of the Suzuki button (pre-subtotal information including the clerk code of the clerk in charge ``Suzuki'', the device number of the device, the sales price confirmation data for side dish A, the membership card information of card C1, and the membership card information of card 2) and stores it in the memory unit 102.

[0113] When the store clerk "Suzuki" operates the prepared food C button on the registration screen of Figure 33, then sets the tare weight (8 g) of the container to hold the prepared food C, and then reads customer C's card C3, the registration and settlement device 10 displays a registration screen such as that shown in Figure 34.

[0114] 34, the operation of the clerk button in the clerk tab is enabled. In other words, the registration settlement device 10 has not yet determined the selling price of the product (prepared food C), but has read the membership card (card C3), and therefore has enabled the operation of the clerk button in order to link the membership card (card C3) with the clerk (the clerk in charge, "Suzuki").

[0115] When the sales clerk "Suzuki" operates his / her own Suzuki button on the registration screen of Fig. 34, the registration and settlement device 10 displays a registration screen as shown in Fig. 35. The registration and settlement device 10 does not display the next screen, the registration screen of Fig. 35, until one of the sales clerk buttons is operated on the registration screen of Fig. 34. In other words, the registration and settlement device 10 restricts the progress of the next process (for example, in the scene of Fig. 34, the process of accepting the placement of purchased products in a container on the registration screen of Fig. 35) until it acquires the sales clerk code.

[0116] In the registration screen of FIG. 35, the operation of the clerk button in the clerk tab is disabled. In other words, the registration settlement device 10 has completed the linking of the membership card (card C3) with the clerk (the clerk in charge "Suzuki") by the operation of the clerk button, but the sales price of the product (prepared food C) has not been determined, so the operation of the clerk button is disabled. In addition, in the registration screen of FIG. 35, "C1" indicating that card C1 has been read, "C2" indicating that card C2 has been read, and "C3" indicating that card C3 has been read (the type of the read membership card is C3) are displayed in the upper right corner. "C3" is the card type information read from card C3, or information based on the card type information. The circle 3 attached to the upper right of the Suzuki button indicates that three membership cards (card C1, card C2, card C3) have been read for the customer (customer a) who is handled by the clerk in charge "Suzuki". The same applies to the registration screen in FIG.

[0117] When the side dish C is weighed in a container (8 g) on ​​the registration screen of FIG. 35 (the weighing value is 138 g), the registration and settlement device 10 displays a registration screen as shown in FIG.

[0118] In the registration screen of Fig. 35, the operation of the clerk button in the clerk tab is enabled. In other words, the registration and settlement device 10 enables the operation of the clerk button because the sales price of the relevant product (prepared dish C) has been confirmed.

[0119] When the sales clerk "Suzuki" operates his / her own Suzuki button on the registration screen of FIG. 36, the registration and settlement apparatus 10 displays a registration screen as shown in FIG.

[0120] In the registration screen of Fig. 37, "C1", "C2", and "C3" on the upper right side have been deleted. In other words, when the registration of the product (prepared food C) is completed, the relationship between the registration settlement device 10 and the responsible store clerk "Suzuki" is temporarily severed (because another store clerk can now interrupt), so the registration settlement device 10 deletes "C1", "C2", and "C3" on the upper right side.

[0121] In addition, the registered settlement device 10 generates pre-subtotal information for the side dish C based on the operation of the Suzuki button (pre-subtotal information including the clerk code of the clerk in charge ``Suzuki'', the device number of the device, the sales price confirmation data for the side dish C, and the membership card information of the card C3) and stores it in the memory unit 102.

[0122] When the sales clerk "Suzuki" operates the subtotal button for sales clerk Suzuki on the registration screen of FIG. 37, the registration and settlement device 10 displays a settlement screen (subtotal screen) as shown in FIG.

[0123] 38, point information (number of owned points) of cards C1, C2, and C3 is displayed on the upper right side. That is, the registered settlement device 10 displays the point information of cards C1, C2, and C3 on the upper right side based on the pre-subtotal information of the first side dish A (specifically, the membership card information of cards C1 and C2) and the pre-subtotal information of the second side dish C (specifically, the membership card information of card C3).

[0124] When the registration and settlement device 10 reads the card C4 of customer c on the settlement screen of FIG. 38, it displays a registration screen as shown in FIG.

[0125] 39, the point information of cards C1, C2, C3, and C4 is displayed on the upper right side of the settlement screen. That is, the registration settlement device 10 displays information on the membership cards (cards C1, C2, and C3) read when registering products, as well as the membership card (card C4) read after operating the subtotal button for Suzuki clerk.

[0126] As described above, the registered settlement device 10 displays the settlement screen (subtotal screen) based on the operation of the subtotal button (subtotal button that also specifies the clerk code). In other words, when the subtotal screen is displayed, the product and the clerk code are linked (the clerk code is specified). Therefore, if the membership card is read while the subtotal screen is displayed, the clerk does not need to operate the clerk button (Figure 38 → Figure 39). In other words, the membership card read while the subtotal screen is displayed (period 10 described above) simply needs to be linked to the clerk code already specified by the operation of the subtotal button, so when the membership card is read while the subtotal screen is displayed, no operation is required to obtain the clerk code to be linked to the membership card (operation of the clerk button).

[0127] When the clerk "Suzuki" operates the deposit / present button on the settlement screen in Fig. 39, the registration and settlement device 10 pops up a small screen (deposit amount input screen) (not shown). When the clerk "Suzuki" operates the deposit amount for customer c by inputting 1181 (yen) on the small screen and operates the confirm button, the registration and settlement device 10 erases the small screen and displays a settlement screen (settlement completion screen) as shown in Fig. 40. When a predetermined time (e.g., 5 seconds) has elapsed, the registration and settlement device 10 displays the registration screen (initial screen) shown in Fig. 5.

[0128] (To cancel a scanned membership card) 41 to 50 are examples of displays relating to the cancellation of a membership card. As shown in Figures 29 to 40, it is assumed that the membership cards of customer c (cards C1, C2, C3, and C4) are read. It is also assumed that there is no pre-subtotal information for the process category "0 (before settlement begins)" or "1 (during settlement)" for any customer other than customer c.

[0129] For example, when the clerk "Suzuki" operates the member card cancellation button on the registration screen of FIG. 30 (the registration screen on which the card C1 for customer c has been read), the registration settlement device 10 displays a registration screen as shown in FIG. 41. When the member card cancellation button is operated, the registration settlement device 10 switches from the side dish tab to the clerk tab in order to specify the customer (the clerk in charge) whose member card is to be cancelled. Since there is no customer who has read the member card other than the customer (customer c) of the clerk in charge "Suzuki", the registration settlement device 10 disables the operation of the clerk buttons other than the Suzuki button in the clerk tab. The circle 1 on the upper right of the Suzuki button indicates that one member card (card C1) has been read for the customer (customer a) who is handled by the clerk in charge "Suzuki". The cancel (cancel cancellation) button on the left center is a button for cancelling the cancellation of the member card. When the cancel (cancel cancellation) button is operated, the screen returns to the original screen (the screen on which the member card cancellation button was pressed).

[0130] Also, for example, when the sales clerk "Suzuki" operates the member card cancellation button on any of the registration screens in Figures 31 to 33 (registration screens on which cards C1 and C2 have been read for customer c), the registration and settlement device 10 displays a registration screen as shown in Figure 42. The circle 2 in the upper right corner of the Suzuki button indicates that two member cards (card C1, card C2) have been read for the customer (customer a) that the sales clerk "Suzuki" is in charge of.

[0131] Also, for example, when the store clerk "Suzuki" operates the membership card cancellation button on the registration screen of Fig. 34 (the registration screen where card C1 for customer c has been read), the registration settlement device 10 displays a registration screen as shown in Fig. 43. Note that the registration screen of Fig. 43 differs from the registration screen of Fig. 42 in that the number of pieces of pre-subtotal information, "1", is displayed within the Suzuki button.

[0132] Also, for example, when the store clerk "Suzuki" operates the member card cancellation button on any of the registration screens in Figures 35 to 37 (registration screens on which cards C1, C2, and C3 have been read for customer c) or the settlement screen in Figure 38 (settlement screen on which cards C1, C2, and C3 have been read for customer c), the registration and settlement device 10 displays a registration screen such as that shown in Figure 44. The circle 3 in the upper right corner of the Suzuki button indicates that three member cards (card C1, card C2, and card C3) have been read for the customer (customer a) that the store clerk "Suzuki" is in charge of.

[0133] Also, for example, when the sales clerk "Suzuki" operates the member card cancellation button on the settlement screen in Fig. 39 (a settlement screen in which cards C1, C2, C3, and C4 for customer c have been read), the registration and settlement device 10 displays a registration screen as shown in Fig. 45. The circle 4 in the upper right corner of the Suzuki button indicates that four member cards (cards C1, C2, C3, and C4) have been read for the customer (customer a) that the sales clerk "Suzuki" is in charge of.

[0134] When the sales clerk "Suzuki" operates the Suzuki button on the registration screen of FIG. 44, the registration settlement device 10 displays a registration screen as shown in FIG. 46. In addition to a cancel (cancel cancellation) button, a cancel button is displayed on the left center, which accepts the cancellation of each of the three read member cards (cards C1, C2, and C3) of the customer (customer a) that the sales clerk "Suzuki" is in charge of. For example, when the cancel button for card C1 is pressed, card C1 is cancelled and the screen returns to the original screen (the screen on which the member card cancel button was pressed). The same applies to cards C2 and C3. The same applies to the registration screen of FIG. 47.

[0135] When the sales clerk "Suzuki" operates the Suzuki button on the registration screen of Fig. 45, the registration and settlement device 10 displays a registration screen as shown in Fig. 47. In addition to a cancel (cancel cancellation) button, a cancel button is displayed on the left center, which accepts cancellation of each of the four read member cards (card C1, card C2, card C3, card C4) of the customer (customer a) that the sales clerk "Suzuki" is in charge of.

[0136] In addition, when the cancel member card button is operated on the checkout screen, the selection of the clerk button may be omitted. For example, instead of the transition from the operation of the cancel member card button on the checkout screen of FIG. 38 to the registration screen of FIG. 44 to the operation of the Suzuki button on the registration screen of FIG. 44 to the registration screen of FIG. 46, the transition may be from the operation of the cancel member card button on the checkout screen of FIG. 38 to the checkout screen of FIG. 48. Also, instead of the transition from the operation of the cancel member card button on the checkout screen of FIG. 39 to the registration screen of FIG. 45 to the operation of the Suzuki button on the registration screen of FIG. 45 to the registration screen of FIG. 47, the transition may be from the operation of the cancel member card button on the checkout screen of FIG. 39 to the checkout screen of FIG. 49. In the case of the transition from FIG. 38 to FIG. 48 (the transition from FIG. 39 to FIG. 49), the member card to be cancelled is limited to the member card of the customer undergoing checkout processing.

[0137] In Figures 41 to 49, it has been explained that there is no pre-subtotal information for processing category "0 (before settlement begins)" or pre-subtotal information for processing category "1 (settlement in progress)" for anyone other than customer C. However, if there is pre-subtotal information for processing category "0 (before settlement begins)" or pre-subtotal information for processing category "1 (settlement in progress)" for multiple customers whose membership cards have already been read, the registered settlement device 10 may display a registration screen such as that shown in Figure 50 when the membership card cancellation button is operated. For example, if two membership cards have been read for customer c and one membership card has been read for customer d at the time the registration screen in Figure 23 (registration screen at the point when registration of side dish A for customer c of responsible clerk "Suzuki" has been completed → registration of side dish D for customer d of responsible clerk "Tanaka") is displayed, then it will be possible to operate the membership card cancellation button on the registration screen in Figure 23, but if the membership card cancellation button is operated, the registration settlement device 10 will display both the Tanaka button and the Suzuki button as operable, as shown in Figure 50.

[0138] The display on the store clerk display unit 103 of the registered settlement apparatus 10 has been described above using Figures 5 to 50, but as shown in Figures 29 to 50, the registered settlement apparatus 10 can read the membership card as appropriate, or cancel the membership card as appropriate. Examples of situations in which the membership card is cancelled include when a different membership card that can be used alternatively to the read membership card is used, or when a membership card in the name of the requester who has requested the purchase (a membership card of the same type as the read membership card in the user's name) is used instead of the read membership card in the user's name.

[0139] (Subtotal button) The subtotal button is not displayed on the registration screen (initial screen) of Figure 5 to which is transitioned from the settlement screen (settlement completion screen) of Figure 12, the registration screen (initial screen) of Figure 5 to which is transitioned from the settlement screen (settlement completion screen) of Figure 19, the registration screen (initial screen) of Figure 5 to which is transitioned from the settlement screen (settlement completion screen) of Figure 25, and the registration screen (initial screen) of Figure 5 to which is transitioned from the settlement screen (settlement completion screen) of Figure 40, that is, on the registration screen (initial screen) displayed after the transaction is completed, however, the subtotal button may be displayed on the registration screen (initial screen) displayed after the transaction is completed. Specifically, when the registration screen (initial screen) is displayed, if pre-subtotal information with processing category "0 (before checkout has begun)" exists (if there is a customer who has registered a product but has not yet started checkout), the subtotal button for that clerk (the clerk with the clerk code included in the pre-subtotal information; the clerk serving the customer) (a subtotal button that also specifies the clerk code for that clerk) will be displayed (either after a specified operation or without a specified operation).

[0140] For example, the subtotal button for clerk Suzuki is displayed on the registration screen (initial screen) in Fig. 5, which is transitioned from the payment screen (payment completion screen) in Fig. 25. In other words, when the registration screen (initial screen) is displayed, pre-subtotal information for process category "0 (before payment begins)" for clerk "Suzuki" in charge of customer c is present, so the subtotal button for clerk Suzuki is displayed. Note that clerk "Suzuki" has started registering customer c's second item (prepared dish C) without operating the subtotal button for clerk Suzuki (Fig. 26).

[0141] Also, for example, in the case of the above-mentioned "Example 1 of interrupt processing" (when 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 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 products 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] For example, in the registration screen of Fig. 23, in addition to the subtotal button for clerk Tanaka, a subtotal button for clerk Suzuki may be displayed. In other words, when the above registration screen is displayed, there is pre-subtotal information for processing category "0 (before settlement begins)" for "Suzuki", the clerk in charge of customer c, and pre-subtotal information for processing category "0 (before settlement begins)" for "Tanaka", the clerk in charge of customer d, so in addition to the subtotal button for clerk Tanaka, a subtotal button for clerk Suzuki may be displayed.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] 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 of the corresponding clerk (the clerk serving the customer) may be made operable in the clerk tab, and the subtotal button of 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 of 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. That is, regardless of the number of clerks serving customers in a state after product registration and before settlement starts, the subtotal button for that clerk may be displayed after the operation of the clerk button in the clerk tab.

[0151] (Commuting) The registration and settlement device 10 may be capable of managing clock-in and clock-out. For example, the registration and settlement device 10 may be capable of accepting a clock-in operation when a store clerk comes to work, and accepting a clock-out operation when the store clerk leaves work.

[0152] 51 to 54 are examples of displays relating to the reception of clock-in and clock-out notifications. Instead of the registration screen (initial screen) shown in Fig. 5, a registration screen (initial screen) as shown in Fig. 51 may be displayed. The registration screen (initial screen) of Fig. 51 has a clock-in / clock-out tab instead of a container tab on the center right side, and a tare container button is displayed at the bottom instead of a tare button. The functions under the tare tab on the registration screen (initial screen) of Fig. 5 are realized after operating the tare container button on the registration screen (initial screen) of Fig. 51.

[0153] It is assumed that the clerks "Kobayashi", "Tanaka", and "Nakamura" are already working, and that they have arrived at work in the following order: "Nakamura" → "Kobayashi" → "Tanaka". It is also assumed that the clerk "Suzuki" has just arrived at work.

[0154] When the clerk "Suzuki" who has come to work operates the attendance tab on the registration screen (initial screen) of FIG. 51, the registration and settlement device 10 displays a registration screen as shown in FIG. 52. At the center right of the registration screen of FIG. 52, the clerk buttons of each clerk are displayed as buttons under the attendance tab. The clerk buttons of clerks who are on duty (Kobayashi button, Tanaka button, Nakamura button in FIG. 52) display "On duty", but the clerk buttons of clerks who are not on duty (Suzuki button, Sato button, Takada button in FIG. 52) do not display "On duty". Note that, on the registration screen of FIG. 52, none of the clerk buttons of clerks are selected (not selected).

[0155] The clerk buttons in the attendance tab are arranged from the top left to the bottom right as follows: clerk "Kobayashi" → clerk "Tanaka" → clerk "Suzuki" → clerk "Nakamura" → clerk "Sato" → clerk "Takada", but this order is a fixed order determined in advance. Instead of a fixed order, they may be arranged in the order of the scheduled attendance times on the business day (in the order of earliest attendance). For example, if the attendance times are scheduled to be in the order of clerk "Nakamura" → clerk "Kobayashi" → clerk "Tanaka" → clerk "Suzuki" → clerk "Takada" → clerk "Sato", the clerk buttons in the attendance tab may be arranged from the top left to the bottom right as follows: clerk "Nakamura" → clerk "Kobayashi" → clerk "Tanaka" → clerk "Suzuki" → clerk "Takada" → clerk "Sato". For clerks who are scheduled to be absent on the business day, the clerk buttons may not be displayed in the attendance tab, or may be displayed last. Planned attendance information (work shift information) including attendance times and holidays may be stored in a location that the registered settlement device 10 can refer to (the memory unit 102 of the device itself, the store controller, the management device, or the memory unit of an external server).

[0156] A clock in button and a clock out button are displayed on the center left side of the registration screen in Fig. 52. The clock in button can be operated when the clerk button of a clerk not on duty is selected, and the clock out button can be operated when the clerk button of a clerk on duty is selected. On the registration screen in Fig. 52, both the clerk button of a clerk not on duty and the clerk button of a clerk on duty are not selected, so operation of both the clock in button and the clock out button is disabled.

[0157] When the store clerk "Suzuki" operates his / her own Suzuki button on the registration screen of Fig. 52, the registration and settlement device 10 displays a registration screen as shown in Fig. 53. The Suzuki button is in a selected state, and is displayed in a display mode indicating that it is in a selected state (bold frame in the figure). In addition, because the Suzuki button is in a selected state, the operation of the clock-in button is enabled.

[0158] When a selected clerk button is operated, the clerk button switches from the selected state to the unselected state. For example, if clerk Suzuki operates the Tanaka button by mistake, the operated Tanaka button will be selected, but if the selected Tanaka button is operated again, the Tanaka button will return to the unselected state. When a clerk button other than the selected clerk button is operated, the selected clerk button will switch to the unselected state and the operated clerk button will switch from the unselected state to the selected state. For example, if clerk Suzuki operates the Tanaka button by mistake, but operates the original Suzuki button without operating the selected Tanaka button, the selected Tanaka button will return to the unselected state and the Suzuki button will become selected.

[0159] When the store clerk "Suzuki" operates the clock-in button on the registration screen of Fig. 53, the registration and settlement device 10 displays the registration screen shown in Fig. 54. The Suzuki button is switched to a non-selected state and displays "On Duty."

[0160] That is, when the clerk button of a clerk not on duty (e.g., Suzuki button) is in a selected state, the clock-in button can be operated, and when the clock-in button is operated, the clock-in time of the clerk is stored (e.g., stored in a store controller, management device, external server, etc.), the clerk button of the clerk is switched from a selected state to a non-selected state, and "on duty" is displayed. The same is true when clocking in. Although not shown in the figure, when the clerk button of a clerk on duty (e.g., Kobayashi button) is in a selected state, the clock-out button can be operated, and when the clock-out button is operated, the clock-out time of the clerk is stored (e.g., stored in a store controller, management device, external server, etc.), the clerk button of the clerk is switched from a selected state to a non-selected state, and "on duty" is erased.

[0161] The registration and settlement device 10 may switch to the original tab (the tab before the clock-in / clock-out tab was operated) when a predetermined time (e.g., 5 seconds) has elapsed since the start of displaying the registration screen in Fig. 54 (the registration screen after the clock-in operation is completed), or may switch to the prepared food tab regardless of which tab was the original tab when a predetermined time (e.g., 5 seconds) has elapsed since the start of displaying the registration screen in Fig. 54. The same applies when a predetermined time has elapsed since the start of displaying the registration screen after the clock-out operation is completed (not shown).

[0162] Naturally, the operation results (operation contents) of the clock-in operation (Figs. 52 to 54) in one registered settlement device 10 are also reflected in the other registered settlement devices 10. In other words, when a clerk button is displayed in the clock-in / clock-out tab in the registered settlement device 10-1 as in Fig. 54, the clerk button is also displayed in the clock-in / clock-out tab of the other registered settlement device 10-2. The same is true for the operation results of the clock-out operation in one registered settlement device 10. In other words, the clerk only needs to perform the clock-in / clock-out operation in any of the registered settlement devices 10.

[0163] 51 to 54 show an example in which the clock-in operation is performed by operating the clock-in / out tab from the registration screen (initial screen), but the clock-in operation may be performed by operating the clock-in / out tab from a screen (registration screen, settlement screen) other than the registration screen (initial screen). In other words, the registration and settlement device 10 can interrupt the clock-in operation and execute the clock-in process even from a screen being operated by the clerk on duty (the clerk in charge). The same applies to the clock-out operation (clock-out process).

[0164] Note that the operation to clock out may be prohibited (restricted) for a clerk who is currently in charge of a customer. As an example, when a certain clerk operates (selects) the clerk button (their own clerk button) in the attendance tab and operates the clock out button, if pre-subtotal information of processing category "0 (before settlement begins)" or processing category "1 (during settlement)" that includes the clerk code of that clerk exists, for example, an error message may be displayed and the clock out process may not be accepted.

[0165] (Staff button on Staff tab) 55 to 58 are display examples of the clerk button in the clerk tab. Starting from the scene in Figure 54 (where four staff members, clerk "Kobayashi", clerk "Tanaka", clerk "Nakamura", and clerk "Suzuki", are on duty), when a customer instructs one clerk (one of the clerks on duty, "Kobayashi", "Tanaka", "Nakamura", or "Suzuki") to purchase 150g of side dish A, and the clerk who receives the instruction (the clerk in charge) sets a tare weight (10g), puts side dish A in the tare and weighs it (the measured value including the tare weight is 160g), the registration and settlement device 10 displays a registration screen as shown in Figure 55. In the registration screen in Figure 55, the clerk buttons for the clerks on duty are displayed, and the clerk buttons for the clerks off duty are not displayed. Additionally, the clerk buttons for the clerks on duty are displayed from the top left to the bottom right in the order in which they come to work (clerk "Nakamura" → clerk "Kobayashi" → clerk "Tanaka" → clerk "Suzuki").

[0166] The registration and settlement device 10 displays a registration screen as shown in FIG. 56 when, in the scene of FIG. 55 (where four staff members, clerk "Kobayashi", clerk "Tanaka", clerk "Nakamura", and clerk "Suzuki", are on duty), clerk "Kobayashi" leaves work, and after clerk "Kobayashi" leaves work, a customer instructs one clerk (one of clerks "Tanaka", "Nakamura", and "Suzuki" on duty) to purchase 100g of side dish A, and the clerk who receives the instruction (the clerk in charge) sets a tare weight (10g), puts side dish A in the tare, and weighs it (the measured value including the tare weight is 110g). In the registration screen of FIG. 56, the display positions of the clerk buttons of the staff members on duty (clerk "Tanaka", clerk "Nakamura", and clerk "Suzuki") remain unchanged, but the clerk button of clerk "Kobayashi", who has left work, is erased. In other words, the registration and settlement device 10 leaves the display position (original display position) of the erased clerk button empty (so as not to place buttons of other clerks on duty in the empty position).

[0167] The registration and settlement device 10 displays a registration screen as shown in Figure 57 when, from the scene in Figure 56 (a scene in which three employees, clerk "Tanaka", clerk "Nakamura", and clerk "Suzuki", are on duty), clerk "Takada" comes to work, clerk "Nakamura" leaves work after clerk "Takada" comes to work, and after clerk "Nakamura" leaves work, a customer instructs one clerk (one of clerks "Tanaka", "Suzuki", and "Takada" on duty) to purchase 120g of side dish A, and the clerk who receives the instruction (the clerk in charge) sets a tare weight (10g), puts side dish A in the tare and weighs it (the measured weight including the tare weight is 130g), in the registration screen in Figure 57. In the registration screen in Figure 57, the Takada button is displayed in the original position of the Kobayashi button, and the Nakamura button is erased.

[0168] On the other hand, in the scene of Fig. 56, when clerk "Nakamura" leaves work, clerk "Takada" comes to work after clerk "Nakamura" leaves work, and after clerk "Takada" comes to work, a customer instructs one clerk (one of clerks "Tanaka", "Suzuki", or "Takada" on duty) to purchase 120g of side dish A, and the clerk who receives the instruction (the clerk in charge) sets a tare weight (10g) and puts side dish A in the tare and weighs it (the measured weight including the tare weight is 130g), the registration and settlement device 10 displays a registration screen as shown in Fig. 58. In the registration screen of Fig. 58, the Nakamura button is erased and the Takada button is displayed in the original display position of the Nakamura button.

[0169] In other words, the registered settlement device 10 displays clerk buttons in the order of arrival from top left to bottom right until a clerk leaves work (Figure 55), and if a clerk arrives to work after one or more other clerks have left work and an empty position has been created due to the deletion of the clerk button of one or more other clerks, the registered settlement device 10 displays the clerk button of the clerk who arrived to work after the other one or more clerks have left work in that empty position (if there are two or more empty positions, the highest position in priority order from top left to bottom right) (Figures 57 and 58).

[0170] According to Figures 56 to 58, the display positions of the clerk buttons (Tanaka button, Suzuki button) of the clerks who continue to work during this time (clerk "Tanaka" and clerk "Suzuki") are fixed even if other clerks clock out or clock in during this time (clerk "Nakamura" clocks out and clerk "Takada" clocks in). In other words, the display positions of each clerk's clerk button are fixed all day even if other clerks clock out or clock in, so it is unlikely that the clerk button will be pressed by mistake, and there is no need to search for your own clerk button every time another clerk clocks out or clocks in.

[0171] The above describes the system 1 according to the embodiment, and the system 1 allows for more efficient reading of the membership card. The system 1 also allows for easy operation of clocking in and out at the sales floor (using the registration and settlement device 10) (Figs. 51 to 54). The system 1 also displays screens that correspond to the clocking in and out status (Figs. 55 to 58), making the operation easy to understand and reducing operational errors.

[0172] (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 (26). In addition, the following (1) to (26) may be appropriately combined with each other.

[0173] (1) In the above embodiment, when a product is specified, an example is described in which the product tab is switched to the clerk tab (for example, FIG. 5 → FIG. 6), 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 (for example, FIG. 6 → FIG. 7) or when the purchase weight (sales price) is confirmed (for example, FIG. 7 → FIG. 8).

[0174] (2) 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.

[0175] (3) 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 a 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.

[0176] (4) In the above embodiment, an example was described in which a clerk code was used to identify one or more products designated by each customer. However, 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. The 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. The icon to be operated by each clerk may be determined in advance. If the icon to be operated by each clerk is not determined in advance, the 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 the 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.

[0177] (5) In the above embodiment, an example of identifying a product by operating a product button has been described, but the method of identifying the product is not limited to this. For example, the product may be identified by inputting a PLU part number, scanning a barcode, or using a wireless device.

[0178] (6) In the above embodiment, the registration and settlement device 10 has been described as displaying a message indicating that registration for the next customer is possible (Figures 12, 19, 25, and 40) and a message indicating that a store clerk needs to be selected (entering a store clerk code by operating the store clerk button) (Figures 29 and 34). However, the message may be output by voice instead of or in addition to being displayed.

[0179] (7) In the above embodiment, the registration and settlement device 10 has been described as displaying a message indicating that selection of a clerk (entering a clerk code by operating the clerk button) is required when the membership card is read before the clerk button is operated (Figs. 29 and 34). However, a message indicating that selection of a clerk is required may also be displayed when the selling price of a product is finalized, i.e., when the registration of one product is finalized (Figs. 8, 15, 22, 27, 32, 36, 55 to 58). For example, the message "Please select a clerk" displayed on the registration screen of Fig. 29 etc. may also be displayed on the registration screen of Fig. 8 etc.

[0180] The registered settlement device 10 may display a message including the reason (purpose) for selecting a store clerk. For example, when the sales price of a product is confirmed, the registered settlement device 10 may display a message such as "Please select a store clerk to link the product to a store clerk," and when the membership card is read before the operation of the store clerk button, the registered settlement device 10 may display a message such as "Please select the store clerk button to link the read membership card to a store clerk."

[0181] (8) In the above embodiment, an example was described in which a clerk is selected (a clerk code is input by operating the clerk button) when the membership card is read before the clerk button is operated, and then a clerk is selected (a clerk code is input by operating the clerk button) when the selling price of the product is confirmed (when the product is put in a container and weighed, and the weight value stabilizes) (FIGS. 29 to 33, 34 to 37). In other words, when the membership card is read to register one product, an example was described in which a clerk is selected twice (once after the membership card is read and once after the selling price of the product is confirmed).

[0182] When the registration settlement device 10 reads the membership card during the original clerk selection stage (between the time when the product sales price is finalized and the clerk selection is made; period 4 or period 8 described above), the registration settlement device 10 may execute either of the following control (a) or (b).

[0183] (a) The operation of the clerk button is requested twice. In other words, the registration and settlement device 10 was waiting for the operation of the clerk button to link the product because the selling price of the product had been confirmed, but since the membership card was read while waiting for the operation, the registration and settlement device 10 further waits for the operation of the clerk button to link the membership card.

[0184] In the case of (a) above, the registration settlement device 10 may accept the first operation of the clerk button as an operation for linking the most recent membership card, and may accept the second operation of the clerk button as an operation for linking the original product. When the sales price of the product has been confirmed and the registration settlement device 10 is waiting for the operation of the clerk button for linking the product, it may display a message (message A) such as "Please select a clerk to link the product to a clerk," and if the membership card is read while message A is displayed, it may display a message (message B) such as "Please select the clerk button to link the read membership card to a clerk," instead of message A, and if the clerk button is operated for the first time, it may display message A instead of message B. Note that if the clerk button is operated for the second time, the displayed message A is erased.

[0185] Alternatively, in the case of (a) above, the registration settlement device 10 may accept the first operation of the clerk button as an operation for linking the original product, and the second operation of the clerk button as an operation for linking the most recent membership card. The registration settlement device 10 may display message A when waiting for the operation of the clerk button for linking the product because the sales price of the product has been confirmed, and may continue to display message A even if the membership card is read while message A is being displayed, and may display message B instead of message A when the clerk button is operated for the first time. Note that when the clerk button is operated for the second time, the message B being displayed is erased.

[0186] (b) Requests one operation of the clerk button. In other words, the registration and settlement device 10 combines the selection of the clerk by determining the product's selling price and the selection of the clerk by reading the membership card into one operation. In the case of the control of (a) above, the operation of the clerk button overlaps, so if it is possible to combine them into one operation, it is more efficient to do so.

[0187] In the case of (b) above, the registration settlement device 10 may display message A when the sales price of the product has been determined and the device is waiting for the operation of the clerk button to link the product, and when the member card is read while the message A is being displayed, a message such as "Please select the clerk button to link the product and the read member card to the clerk" (message C) may be displayed instead of message A. The registration settlement device 10 may also display a message indicating that the selection of the clerk by determining the sales price of the product and the selection of the clerk by reading the member card have been combined into one. For example, the registration settlement device 10 may display message A when the sales price of the product has been determined and the device is waiting for the operation of the clerk button to link the product, and may continue to display message A even when the member card is read while the message A is being displayed, and when the clerk button is operated, a message such as "The linking of the member card has also been completed" (message D) may be displayed instead of message A. Note that message D is erased, for example, when a predetermined time (e.g., 3 seconds) has elapsed.

[0188] (9) In the above embodiment, the barcode printed on the member card is scanned to read the member card (member card information), but a two-dimensional code may be used. The member card may be a magnetic card or an IC card. That is, the registration settlement device 10 may have a card reading unit into which the card is inserted and read, and the member card may be read by inserting the card into the card reading unit. The registration settlement device 10 may have a card swipe unit which reads the card by swiping it, and the member card may be read by swiping the card on the card swipe unit. The registration settlement device 10 may have a card touch unit which reads the card by touching it, and the member card may be read by touching the card on the card touch unit. The above-mentioned reading operation may be performed by a store clerk (store clerk in charge) or by the customer. Although the member card is referred to as a member card, it is not limited to cards as long as it is capable of acquiring customer identification information, etc. Customer identification information, etc. may be acquired from the customer's electronic device (mobile terminal, wearable terminal). For example, a membership card displayed on the electronic device may be read, or membership card information may be read from an IC chip in the electronic device.

[0189] (10) Although not explained in the above embodiment, card type information of a membership card that can be used at the store is stored in a location that the registered settlement device 10 can refer to (the memory unit 102 of its own device, the store controller, the management device, the memory unit of an external server), and when the registered settlement device 10 acquires membership card information for a membership card (membership card information including card type information), it determines whether the membership card is a membership card that can be used at the store based on the card type information, and if the membership card is not a membership card that can be used at the store, it may display an error message stating that the membership card is not a membership card that can be used at the store.

[0190] (11) In the above embodiment, the barcode printed on the member card is scanned to read the member card (member card information), but the member card information may be acquired after a declaration of reading operation is performed. For example, a card reading button may be displayed on the registration screen or the settlement screen, or a card reading key may be arranged on the operation unit 107, and the member card information may be acquired after the card reading button (card reading key) is operated. This, which is also related to (9) above, makes it possible to enable a device (e.g., a card reading unit) for acquiring the member card information immediately before acquiring the member card information. Also, a plurality of card reading buttons (a plurality of card reading buttons each assigned with card type information) corresponding to each member card may be displayed, or a similar plurality of card reading keys may be arranged on the operation unit 107, and the member card information may be acquired after the card reading button (card reading key) corresponding to the member card to be read is operated. This makes it possible to enable a device corresponding to the member card to be read.

[0191] (12) In the above embodiment, an example was described in which information indicating that a membership card has been read (e.g., "C1", "C2", "C3") was displayed on the registration screen, but point information (e.g., the number of points held by each membership card, the point expiration date, etc.) may also be displayed. Also, when one or more membership cards have been read, "Obtaining membership information" may be displayed on the upper right or center left of the registration screen.

[0192] (13) In the above embodiment, an example was described in which the number of points held by each read member card was displayed on the settlement screen, but instead of or in addition to the number of points held, the number of points currently acquired, the point expiration date, etc. may be displayed. Furthermore, when multiple member cards are read, points are awarded to each member card (the number of points currently acquired is calculated) based on the awarding criteria of each card (for example, 1 point for every 200 yen), and additional points may be awarded by using the same cards (combination).

[0193] (14) In the above embodiment, an example was described in which the number of membership cards that have been read was displayed on the store clerk button (FIGS. 41 to 47, 50), but instead of or in addition to the number of membership cards, the types of membership cards that have been read, etc. may be displayed. In other words, it is sufficient that the store clerk button visibly displays the acquisition status of membership cards (number of acquired membership cards, types of acquired membership cards, etc.).

[0194] (15) In the above embodiment, an example was described in which pre-subtotal information including a clerk code, sales price determination data, and membership card information was generated, but pre-subtotal information including a clerk code and sales price determination data, and information including a clerk code and membership card information (e.g., card reading information) may be generated. In other words, it is sufficient that the sales price determination data is linked to the clerk code and the membership card information is linked to the clerk code, and the sales price determination data and the membership card information do not have to be directly linked (it is sufficient that they are linked via the clerk code). Furthermore, it is sufficient that the processing category is linked to the clerk code, and it is not necessary that it is directly linked to the sales price determination data or the membership card information. The same applies to the post-subtotal information.

[0195] (16) In the above embodiment, on the registration screen (registration screens in Figures 9, 16, 23, 28, 33, and 37) after the sales price is confirmed and the clerk button is operated (after pre-subtotal information is generated), if a predetermined time (e.g., 5 seconds) has elapsed since the registration screen started to be displayed, or if a product button is operated on the registration screen before the predetermined time has elapsed, the total information in the upper right corner of the registration screen is erased, and if the subtotal button for that clerk in the center left of the registration screen is operated, the settlement screen is displayed. However, the display (maintaining) / erasing of the total information when the registration screen continues to be displayed without operating the subtotal button may be controlled as follows.

[0196] When the total information on the registration screen for the operation of the clerk button after the selling price is determined is estimated to be a continuous operation by the clerk (the same clerk who completed the registration of the product), the display is maintained (the total information (total information of the already registered product) is displayed on the registration screen for the next product). For example, if an operation (e.g., an operation of a product button) occurs within a predetermined time (e.g., 60 seconds) from the start of displaying the registration screen for the operation of the clerk button after the selling price is determined, the operation may be estimated to be a continuous operation by the clerk. In other words, if an operation is performed on the registration screen before a predetermined time has elapsed from the start of displaying the registration screen for the operation of the clerk button after the selling price is determined, the display of the total information is maintained, and even if there is no operation, the display of the total information is maintained until the predetermined time has elapsed. In other words, if there is no operation until a predetermined time has elapsed from the start of displaying the registration screen for the operation of the clerk button after the selling price is determined, the total information is erased. Note that if the clerk button of the clerk is operated by another registered settlement device 10 before the predetermined time has elapsed (if the clerk moves to another registered settlement device 10), the total information may be erased.

[0197] In other words, if the clerk does not immediately proceed to settlement after registering the item, there is a high possibility that the next item will be registered, and since there is also a possibility that the next item will be registered at the relevant settlement device 10, the total information will continue to be displayed unless a predetermined period of time (e.g., 60 seconds) has passed without any operation or the clerk operates the clerk button at another registered settlement device 10.

[0198] (17) In the above embodiment, an example was described in which the operation of the clerk button was enabled (operable) when the selling price was finalized (when pre-subtotal information was generated) and when the membership card was read (for example, Figures 8 and 29), but the operation of the clerk button may also be enabled in other situations.

[0199] For example, which is also related to (16) above, when the prepared food tab on the registration screen is switched to the clerk tab after the clerk button is operated after the selling price is confirmed, the operation of the clerk button may be validated. Also, when the prepared food tab on the registration screen (initial screen) is switched to the clerk tab, the operation of the clerk button may be validated. In the above scene, when the clerk button for a certain clerk is operated and pre-subtotal information for that clerk before the start of settlement (pre-subtotal information including the clerk code for that clerk and having a processing category of "0 (before settlement starts)") exists, information based on the pre-subtotal information for that clerk before the start of settlement (for example, total information, membership card information) may be displayed.

[0200] In other words, the function of the clerk button described in the above embodiment was to complete the registration of individual products and link the products to the clerk (to generate pre-subtotal information) and to link the membership card to the clerk, but the clerk button may also have a function to identify and display registered product information (pre-subtotal information) related to the clerk.

[0201] (18) In the above embodiment, the operation at the time of clocking in on the clock-in / clock-out tab is described as operating the clerk button (operating so as to be in a selected state) → operating the clock-in button, and the operation at the time of clocking out is described as operating the clerk button (operating so as to be in a selected state) → operating the clock-out button, but the operations at the time of clocking in / clock-out are not limited to this. The first operation of the clerk button may be clocking in, and the second operation may be clocking out. For example, when the clerk "Suzuki" operates the Suzuki button when clocking in, the clock-in time of the clerk "Suzuki" is stored and "on duty" is displayed on the Suzuki button, and when the clerk "Suzuki" operates the Suzuki button with "on duty" displayed on it when clocking out, the clock-out time of the clerk "Suzuki" is stored and "on duty" is erased from the Suzuki button. In other words, there may be no operation of the clock-in button or the clock-out button, and only the clerk button may be operated, and the first operation on the business day may be clocking in and the second operation may be clocking out.

[0202] (19) In the above embodiment, an example was described in which the clock-in / clock-out operation was performed in the clock-in / clock-out tab prepared separately from the clerk tab, but the clock-in / clock-out operation may also be performed in the clerk tab. For example, the operation of the clerk button when registering a product (for example, the operation of the clerk button as the clerk in charge in the scenes of Figures 8 and 15) may be a normal touch, and the operation of the clerk button when clocking in / out may be a long press. For example, when there is a long press of the Suzuki button in the clerk tab, the registration settlement device 10 may display a small screen displaying the clock-in button, the clock-out button, and the cancel button. Also, for example, the registration settlement device 10 may treat the first long press of the Suzuki button in the clerk tab as clocking in and the second long press as clocking out.

[0203] (20) In the above embodiment, an example was described in which the registration and settlement device 10 has a function of accepting clock-in and clock-out operations (Figures 51 to 54) and a function of controlling the display (display position, etc.) of the clerk button depending on the clock-in and clock-out status (Figures 54 to 58). However, the registration and settlement device 10 may also control the display of the clerk button depending on the clock-in and clock-out status obtained in a device other than the registration and settlement device 10 (for example, a general attendance time reception device).

[0204] (21) 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)).

[0205] (22) 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.

[0206] (23) 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.

[0207] (24) 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.

[0208] 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.

[0209] (25) 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.

[0210] (26) 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.

[0211] 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.

[0212] Also, instead of the registration and settlement device 10, another device (for example, a cloud server) may calculate the total amount from the unit price and the purchased weight. The registration and 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 and settlement device 10, and the registration and settlement device 10 may display screens (screens in Figures 5 to 58) generated by the cloud server using a browsing function. The same applies to the registration device 20, the registration and settlement device 30, and the registration device 40.

[0213] <Overview of the embodiment> [Technical field] The present invention relates to a registration device and a program. [Background technology] 2. Description of the Related Art A weighing pricing system that reads a membership card and applies a discount price is known (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 reading member cards. The present invention has been made in consideration of such circumstances, and has an object to provide a technique that enables more suitable reading of member cards. [Means for solving the problem]

[0214] (1) One aspect for solving the above-mentioned problems is a registration device (e.g., registration and settlement device 10, registration device 20, registration and settlement device 30, registration device 40) that includes a clerk identification information acquisition means (e.g., a clerk button) for acquiring clerk identification information (e.g., a clerk code) capable of identifying a clerk, a customer identification information acquisition means (e.g., a scanner unit, a card reading unit) for acquiring a customer's customer identification information (e.g., membership card information), and a guidance means for outputting guidance information to the clerk (e.g., the message in Figures 12, 19, 25, and 40 indicating that the next customer can be registered, and the message in Figures 29 and 34 indicating that a clerk selection (entering a clerk code by operating the clerk button) is required), wherein, if customer identification information is acquired by the customer identification information acquisition means before the clerk identification information is acquired by the clerk identification information acquisition means, the guidance means outputs guidance information to the clerk to acquire the clerk identification information (the message in Figures 29 and 34 indicating that a clerk selection is required). According to the registration device of (1), the reading of the membership card can be more efficiently performed. For example, since the read membership card information is linked to the sales clerk (purchased item) regardless of the timing of reading the membership card, the membership card can be read at any timing (particularly, before the acquisition of sales clerk identification information). In other words, when the registration device of (1) acquires customer identification information before acquiring sales clerk identification information, it outputs guidance information to the effect that sales clerk identification information will be acquired. Therefore, if the sales clerk acquires the sales clerk identification information according to the guidance information, the customer identification information acquired before acquiring the sales clerk identification information can be linked to the sales clerk identification information acquired after acquiring the customer identification information. Note that when customer identification information is acquired after acquiring sales clerk identification information, it is only necessary to link the customer identification information to the sales clerk identification information already acquired, and therefore there is no need to output guidance information to the sales clerk.

[0215] (2) A registration device as described in (1) is characterized in that it is provided with a control means (e.g., a CPU) for controlling the progress of processing, and when customer identification information is acquired by the customer identification information acquisition means before the clerk identification information is acquired by the clerk identification information acquisition means, the control means restricts the progress of the next process (transition to the next screen, processing on the next screen) until the clerk identification information is acquired (e.g., until the clerk button is operated on the registration screen of Figures 29 and 34). According to the registration device of (2), for example, the membership card information can be reliably linked to the sales clerk in charge (purchased item).

[0216] (3) The registration device described in (1) or (2) is characterized in that the clerk identification information acquisition means acquires clerk identification information for each clerk by operating a clerk button, and the clerk button visibly displays the acquisition status of the customer identification information by the customer identification information acquisition means (e.g., the number of member cards that have been read, the type of member cards that have been read, etc.). According to the registration device of (3), for example, the acquisition status of customer identification information for each store clerk (each customer served by the store clerk in charge) can be easily recognized.

[0217] (4) A registration device according to any of (1) to (3), comprising a weighing means, wherein the guidance means outputs guidance information to the effect that store clerk identification information is to be obtained (for example, a message similar to the message in FIG. 29 or FIG. 34 indicating that a store clerk must be selected (enter a store clerk code by operating the store clerk button)) when the selling price of a product is determined based on the purchase weight of the product weighed by the weighing means and the unit price of the product (for example, while the registration screen in FIG. 8, FIG. 15, FIG. 22, FIG. 27, FIG. 32, FIG. 36, FIG. 55 to FIG. 58 is being displayed). According to the registration device of (4), for example, a purchased item whose selling price has been confirmed can be reliably linked to a store clerk.

[0218] (5) A registration device as described in (4), characterized in that when the selling price of a product is determined based on the purchase weight of the product weighed by the weighing means and the unit price of the product, and when clerk identification information is acquired by the clerk identification information acquisition means, the registration device is provided with a linking means for linking the sales price determination information of the product (e.g., sales price determination data) to the clerk identification information acquired by the clerk identification information acquisition means, and when customer identification information is acquired by the customer identification information acquisition means, the linking means further links the customer identification information (e.g., the CPU generates the pre-subtotal information of Figure 4(A)). According to the registration device of (5), for example, the sales price determination information, the store clerk (the customer whom the store clerk is in charge of), and the member card can be easily associated with each other.

[0219] (6) A registration device described in any of (1) to (5), further comprising a customer identification information cancellation means for canceling customer identification information acquired by the customer identification information acquisition means, the customer identification information cancellation means canceling customer identification information designated by a store clerk from among one or more customer identification information linked to one store clerk identification information acquired by the store clerk identification information acquisition means (Figures 41 to 50). According to the registration device of (6), for example, the relevant member card (member card reading) can be easily cancelled for each store clerk.

[0220] (7) One aspect for solving the above-mentioned problem is a program that causes a computer to function as a registration device (e.g., registration and settlement device 10, registration device 20, registration and settlement device 30, registration device 40), and causes the computer to function as a clerk identification information acquisition means that acquires clerk identification information capable of identifying a clerk, a customer identification information acquisition means that acquires the customer identification information of a customer, and a guidance means that outputs guidance information to the clerk, wherein the guidance means outputs guidance information to the effect that the clerk identification information is to be acquired if the customer identification information is acquired by the customer identification information acquisition means before the clerk identification information is acquired by the clerk identification information acquisition means. According to the program (7), like the registration device (1), it is possible to more efficiently read the membership card.

[0221] 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).
