Mode for Carrying Out the Invention

[0009] <Embodiment> FIG. 1 shows a configuration example of a sales system in this embodiment. The sales system in the figure includes weighing and pricing devices 10 (10-1, 10-2, 10-3), settlement devices 20 (20-1, 20-2), a management device 30, a mobile terminal device 40, and a transaction management server 50. In the sales system of this embodiment, a customer registers a product using the mobile terminal device 40 and also performs settlement by operating the settlement device 20.

[0010] The weighing and pricing device 10 calculates the amount for each product based on the weight measured for the product placed on the weighing platform and the unit price per weight, and generates product pricing information for the product including the calculated amount. The product pricing information is transmitted to the mobile terminal device 40 communicably connected to the weighing and pricing device 10.

[0011] The settlement device 20 executes a settlement process according to a customer's operation using the cart information (settlement information) acquired from the transaction management server 50.

[0012] The management device 30 is a higher-level device of the settlement device 20 in the store. The management device 30 in the figure is communicably connected to the settlement device 20. The management device 30 can manage the transaction results in the store, for example, by acquiring the performance information of the settlement process in the store from the settlement device 20. Also, for example, it can monitor the status of the settlement device 20 and give a notification when an abnormality occurs in the settlement device 20. Note that the management device 30 may also be communicably connected to the metering device 10. In this case, for example, the management device 30 may store the information of the product master. The metering device 10 can execute the process corresponding to the registration of the product by using the product master stored in the management device 30.

[0013] The mobile terminal device 40 is a terminal device owned by the customer. In the present embodiment, the mobile terminal device 40 may be a smartphone, a tablet terminal, or the like owned by the customer. Application software (shopping application) corresponding to the sales system of the present embodiment and used by the customer for services related to shopping or the like is installed in the mobile terminal device 40.

[0014] The transaction management server 50 manages transactions in the sales system. Specifically, the transaction management server 50 receives the product registration information transmitted from the mobile terminal device 40 via the network, and generates cart information for each transaction unit based on the received product registration information. The cart information indicates the registration result of the product in the corresponding transaction. The transaction management server 50 transmits the cart information associated with the transaction identifier specified by the cart information request to the settlement device 20 in response to the cart information request transmitted from the settlement device 20.

[0015] Referring to FIGS. 2 and 3, a configuration example of the metering device 10 in the present embodiment will be described. FIG. 2 is a block diagram showing a hardware configuration example of the metering device 10.

Further, the hard disk 107 may store various information generated by the execution of the program. Further, the hard disk 107 may store information regarding the display by the customer display unit 106 and information regarding the printing by the printing unit 110. Note that instead of the hard disk 107, other storage devices such as an SSD (Solid State Drive) may be provided.

[0021] The metering unit 109 measures the weight of products and the like (products and the tare containing the products) placed on the weighing platform 109b, and outputs data indicating the measured value to the CPU 101. The CPU 101 that has acquired the measured value from the metering unit 109 subtracts a predetermined weight (the weight of the tare) from the measured value to calculate the product placed on the weighing platform 109b. Further, the CPU 101 temporarily stores the weight of the product calculated as described above in the RAM 103 and causes it to be displayed on the customer display unit 106.

[0022] The printing unit 110 prints (prints) on a paper medium and issues (outputs) it from the label discharge port 110a (FIG. 3). For example, the printing unit 110 can issue a label to be attached to a product.

[0023] The inter-device communication unit 111 is provided to handle the case of communicating with other metering devices 10 via a predetermined communication network. Note that the communication network with which the inter-device communication unit 111 corresponds may be wired or wireless. Note that the inter-device communication unit 111 may be capable of communicating with the management device 30. The short-range communication unit 112 communicates with the mobile terminal device 40 by a predetermined short-range wireless communication method. The short-range wireless communication method with which the short-range communication unit 112 corresponds may be, for example, Bluetooth (registered trademark).

[0024] FIG. 4 is a perspective view showing an external appearance example of the settlement device 20. The settlement device 20 in the figure includes a scanner unit 204, a customer display unit 206, a change dispenser 260, and an issuing port 210a.

[0025] The scanner unit 204 reads code information. The code information readable by the scanner unit 204 may be a barcode (one-dimensional code) or a two-dimensional code (e.g., QR code (registered trademark), etc.). In the case of this embodiment, the scanner unit 204 is used to read the code information displayed on the portable terminal device 40. Examples of the code information displayed on the portable terminal device 40 include settlement code information, code information arranged on the membership card screen indicating a member identifier, etc., and code information including coupon ticket information. Further, the settlement device 20 may be enabled to execute product registration processing according to, for example, an operation by a store clerk. In this case, the scanner unit 204 may be configured to read the code information as a product code. In the figure, an example is shown in which the scanner unit 204 is fixedly provided on the pedestal portion of the customer display unit 206. However, for example, it may be a handy scanner and may be hooked on a pedestal provided on the side surface of the housing.

[0026] The customer display unit 206 displays settlement-related information for customers. The customer display unit 206 may be configured as a display device having a touch panel.

[0027] The change machine 260 is an automatic change machine that accepts the insertion of banknotes and coins by customers, performs deposit processing, and discharges change, refunds, or banknotes and coins in case of rejection. The change machine 260 includes a banknote management unit 261, a coin insertion slot 264, a coin discharge slot 265, and a rejection slot 266. The coin insertion slot 264, the coin discharge slot 265, and the rejection slot 266 are included in the coin management unit. The banknote management unit 261 includes a banknote insertion slot 262 and a banknote discharge slot 263. The banknote insertion slot 262 is an opening for taking in banknotes inserted by customers. The banknote discharge slot 263 is an opening for discharging banknotes and rejected banknotes. The banknote insertion slot 262 and the banknote discharge slot 263 are configured in two stages. For example, in the banknote management unit 261, the upper stage is the banknote insertion slot 262 and the lower stage is the banknote discharge slot 263.

[0028] The coin insertion slot 264 is an opening for taking in coins inserted by customers. The coin discharge slot 265 is an opening for discharging coins as change, coins when the currency identification unit provided in the change machine 260 fails to identify them, and coins when the currency identification unit identifies them as counterfeit coins. The rejection slot 266 is an opening for discharging coins when a cancellation operation is performed after a deposit. The banknote insertion slot 262 and the coin insertion slot 264 are deposit openings. The banknote discharge slot 263, the coin discharge slot 265, and the rejection slot 266 are withdrawal openings. The issuance port 210a outputs various receipts from the receipt discharge port.

[0029] The change machine 260 and the issuance port 210a project from the customer-side side surface of the counter toward the customer, facing the banknote insertion slot 262, the banknote discharge slot 263, the coin insertion slot 264, the coin discharge slot 265, the rejection slot 266, and the receipt discharge slot. With this arrangement, when a customer stands close to the change machine 260, the risk of the customer's toes hitting the counter is reduced. For example, the change machine 260 and the issuance port 210a are housed in an integrated housing, and this housing projects from the customer-side side surface of the counter.

[0030] FIG. 5 is a block diagram showing a configuration example of the settlement device 20. The settlement device 20 includes a CPU 201, a ROM 202, a RAM 203, a scanner unit 204, a customer display unit 206, a hard disk 207, a printing unit 210, an inter-device communication unit 211, and a coin dispenser 260. These are connected to each other via a bus 219. Note that since the inter-device communication unit 211 is a component provided for communication with a clerk identification tag in the third embodiment described later, it may be omitted in this embodiment.

[0031] The CPU 201 executes various processes for realizing the functions of the settlement device 20 by executing programs. The ROM 202 stores various information. For example, the ROM 202 stores programs executed by the CPU 201. The ROM 202 also stores information related to display by the customer display unit 206 (screen information, message information, etc.). The ROM 202 also stores a device number for identifying the own device. The ROM 202 may also store information related to printing by the printing unit 210 (printing content, print format information, etc.). The scanner unit 204 optically reads the encoded information and stores the read information in the RAM 203. The RAM 203 is used as a work area when the CPU 201 executes processing and calculations. The scanner unit 204 optically reads the encoded information. The scanner unit 204 can read information such as a member number printed as a barcode or the like on a member card, for example.

[0032] The customer display unit 206 is configured as a touch panel, displays information for customers, and accepts operations when the customer touches the screen.

[0033] The hard disk 207 stores various types of information necessary for the settlement device 20 as an auxiliary storage device of the CPU 201. The hard disk 207 may store a program for causing the CPU 201 to execute settlement processing and the like. Further, the hard disk 207 may store various types of information generated when the program is executed. Further, the hard disk 207 may store information related to display by the customer display unit 206 and information related to printing by the printing unit 210. The printing unit 210 prints a receipt or the like on paper and discharges the receipt from the discharge port.

[0034] The device-to-device communication unit 211 communicates with, for example, other settlement devices 20 and management devices 30.

[0035] With reference to FIG. 6, a configuration example of the portable terminal device 40 of the present embodiment will be described. The portable terminal device 40 in the figure includes a CPU 401, a storage unit 402, a RAM 403, a network-compatible communication unit 404, a short-range wireless-compatible communication unit 405, a display unit 406 with a touch panel, an operation unit 407, an imaging unit 408, and a position information acquisition unit 409.

[0036] The CPU 401 realizes various processes in the portable terminal device 40 by executing a program. The storage unit 402 is an auxiliary storage device of the CPU 401 and stores various types of data in addition to the program to be executed by the CPU 401. The RAM 403 is the main storage device of the CPU 401.

[0037] The network-compatible communication unit 404 executes communication compatible with the network via a telephone line or a wireless LAN. The short-range wireless-compatible communication unit 405 performs short-range wireless communication according to, for example, the Bluetooth standard. That is, the short-range wireless-compatible communication unit 405 performs short-range wireless communication with the short-range communication unit 112 in the metering device 10. Thereby, communication between the portable terminal device 40 and the metering device 10 becomes possible.

[0038] The display unit 406 with a touch panel is a display unit combined with a touch panel. The operation unit 407 is outside the display unit 406 with a touch panel, and collectively indicates keys and the like on which operations are performed.

[0039] The imaging unit 408 performs imaging. The mobile terminal device 40 has a code information scanning function using the imaging unit 408. That is, when the mobile terminal device 40 recognizes that code information is included in the captured image obtained by imaging with the imaging unit 408 as a code information scanning function, it acquires the code information from the captured image.

[0040] The code information scanning function using the imaging unit 408 is used for reading the code information attached to a product and reading the connection information code displayed on the weighing device 10 in the shopping application of the present embodiment. Depending on the reading of the code information attached to the product, the product to be registered is specified by the product code included in the code information. Regarding the specification of such a product to be registered, for example, it may be realized by general object recognition processing using the captured image obtained by imaging the product with the imaging unit 408. In this case, as a result of the general object recognition processing, one product may be specified, or a plurality of candidates may be presented. When presenting a plurality of candidates, the product to be registered may be specified by selecting one from among the plurality of candidates presented to the customer.

[0041] The position information acquisition unit 409 measures its own position and acquires position information indicating the measured position. The position information acquisition unit 409 may be configured to include a positioning device corresponding to, for example, GPS (Global Positioning System).

[0042] Referring to FIG. 7, a configuration example of the transaction management server 50 of the present embodiment will be described. The transaction management server 50 in the figure includes a CPU 501, a storage unit 502, a RAM 503, and a communication unit 504.

[0043] By executing a program, the CPU 501 realizes various processes in the transaction management server 50. The storage unit 502 is an auxiliary storage device of the CPU 501, and stores various data in addition to the program to be executed by the CPU 501. The RAM 503 is the main storage device of the CPU 501. The communication unit 504 executes communication with the settlement device 20, the mobile terminal device 40, and the like. Note that a display unit, an operation unit, and the like may also be provided in the transaction management server 50 so that an administrator can perform operations and the like.

[0044] The transaction management server 50 stores customer information as shown in, for example, FIG. 8(A). The customer information shown in FIG. 8(A) includes customer identification information, customer name, customer registration date, cancellation information, customer rank, number of points, and the like. The customer identification information is identification information that uniquely identifies a customer. The customer name is the name or nickname of the customer. The customer registration date is the date and time when the customer registered. The cancellation information is information regarding the cancellation of registered products after registration. The customer rank is a rank according to the purchase record of the customer. Note that when generating customer information for a new customer, customer identification information, customer name, and customer registration date are generated, but since it is before the start of an actual transaction (product registration), other information (cancellation information, etc.) is not generated.

[0045] The transaction management server 50 generates and stores customer identification information, for example, when a customer registers (for example, when the mobile terminal device 40 downloads or installs a shopping application to use the service provided by the transaction management server 50 from an external source (for example, a predetermined server that provides all applications, the transaction management server 50)). Also, the transaction management server 50, for example, acquires information input in the name field of the registration form (input form) using the mobile terminal device 40 when a customer registers, and stores it as the customer name. Further, the transaction management server 50, for example, acquires the current date and time at the time of customer registration, and stores it as the customer registration date.

[0046] Note that, instead of or in addition to storing customer information in the storage unit within its own device, the transaction management server 50 may store part or all of the customer information in another device (such as a file server accessible by the transaction management server 50).

[0047] The store information is obtained from the management device 30 of each store. That is, the transaction management server 50 stores the store information by receiving the store information directly from the management device 30 of each store or indirectly via another device.

[0048] The transaction management server 50 stores store information as shown in, for example, FIG. 8(B). The store information shown in FIG. 8(B) includes store identification information, store name (branch name), store specific information 1, and store specific information 2. The store identification information is identification information that uniquely identifies a store. The store identification information shown in FIG. 8(B) is composed of a store (store number) or company code and a branch code. The store name is the name of the store. The store name shown in FIG. 8(B) is composed of a store (store number) or company and a branch name. The store specific information 1 is information on a two-dimensional code for identifying the store where transactions are conducted (the store where goods are bought and sold). The store specific information 2 is the location information (GPS information) of the store for identifying the store where transactions are conducted. Note that in the example shown in FIG. 8(B), the store identification information and the store specific information 1 are different, but the store identification information and the store specific information 1 may be the same.

[0049] Note that the transaction management server 50 may obtain and store store information and the like from the outside (such as a server (not shown) of the headquarters that oversees each store). Also, instead of or in addition to storing the store information in the storage unit within its own device, the transaction management server 50 may store part or all of the store information in another device (such as a file server accessible by the transaction management server 50).

[0050] The product information is obtained from the management devices 30 of each store or the like. That is, the transaction management server 50 receives the product information directly from the management devices 30 of each store or indirectly via other devices, and stores the product information. Note that the transaction management server 50 may obtain and store the product information from an external source (such as a server (not shown) of the headquarters that oversees each store). Also, instead of or in addition to storing the store information in the storage unit within its own device, the transaction management server 50 may store part or all of the store information in another device (such as a file server accessible by the transaction management server 50).

[0051] The cart information is information for managing individual transactions. The transaction management server 50 generates the cart information at the start of a transaction. Also, the transaction management server 50 updates the cart information as the transaction progresses (each time a product is registered) (it may be understood that the registration of the product has been made when the product is stored in the cart information).

[0052] The transaction management server 50 stores cart information as shown in FIG. 8(C), for example. The cart information shown in FIG. 8(C) includes cart identification information, transaction start date and time, transaction end date and time, customer identification information, registered product information, reserved product information, cancellation information, and the like. The cart identification information is identification information that uniquely identifies the cart (transaction). The cart identification information shown in FIG. 8(C) is composed of store identification information, a date, and a serial number (for example, a serial number for each store and date). The transaction start date and time is the start date and time of the transaction. The transaction start date and time shown in FIG. 8(C) is the generation date and time of the cart information. Note that the transaction start date and time may be the registration date and time of one item of product (the date and time when the registered product information (registered product 1) in FIG. 8(C) was stored). Both the generation date and time of the cart information and the registration date and time of one item of product may be stored separately.

[0053] The transaction end date and time is the end date and time of the transaction. The transaction start date and time shown in FIG. 8(C) is the settlement date and time. The customer identification information is the customer identification information that identifies the customer of the transaction. Note that at the time of generating the cart information, cart identification information, transaction start date and time, and customer identification information are generated, but since it is before the start of the actual transaction (product registration), other information (transaction end date and time, etc.) is not generated. Note that the settlement date and time may be the settlement start date and time or the settlement end date and time. It is also possible to separately store both the settlement start date and time and the settlement end date and time.

[0054] The registered product information (total) is information that is updated each time a product is registered. The registered product information (total) includes the quantity (number of products), estimated subtotal amount (estimated subtotal amount before price calculation by the price determination logic), subtotal amount (subtotal amount after price calculation by the price determination logic), etc. The registered product information (1) is the registration information of one item of product. The registered product information (2) is the registration information of two items of product. Note that in the example shown in FIG. 8(C), the illustration of the registered product information (3) to the registered product information (5) is omitted. The registered product information (N; N is an integer) includes the product code, product name (name of the product), price, etc.

[0055] The registered product information (N) may include the registration date and time of the Nth item of product. That is, the transaction management server 50 may store the registration date and time of the registered product as the registered product information. The registration date and time of each product may also be used as a basis for determining the necessity of applying services such as the time service (service by the selling price determination logic E) and the effect after application.

[0056] The reserved product information (total) is information that is updated each time a reserved product (described later) is registered. The reserved product information (total) includes the quantity (number of products) of the reserved products, the quantity of NON-FILE among the reserved products, the quantity of read NG (operation error confirmation required) among the reserved products, etc.

[0057] "NON-FILE" refers to the situation where the barcode scan in the store was successful (the product code could be read), but the product code is not stored in the product information, or it refers to the product for which the barcode scan in the store was successful, but the product code is not stored in the product information.

[0058] "Reading failure" refers to the situation where the barcode scan in the store failed (the product code could not be read), or it refers to the product for which the barcode scan in the store failed. That is, "reading failure" means, for example, when imaging the product for a certain period of time by image recognition technology but barcode recognition is not achieved, timeout processing can be performed if it can be determined, and it is the product for which timeout processing has been performed. For example, when the barcode cannot be obtained (recognized) correctly due to wrinkles in the package or smudges or dirt on the barcode printing, it is determined as a reading failure. Also, when an illegal operation of pretending to read the barcode and putting it into the basket is detected, it is also determined as a reading failure. Note that the mobile terminal device 40 is equipped with sensors (such as a gyro sensor, an acceleration sensor, a distance sensor, etc.), and the mobile terminal device 40 can detect the situation where the barcode is being read (specifically, the situation where the mobile terminal device 40 is tilted for barcode reading and there is an item (product) at a certain distance from the mobile terminal device 40). And when the barcode cannot be read within a predetermined time (when barcode reading continues for a predetermined time but the barcode cannot be read), as a timeout process, it is regarded as a pending product (reading failure).

[0059] Pending product information (Pending product 1) is the information of one item of pending product. Pending product information (Pending product 2) is the information of two items of pending product. Pending product information (Pending product 3) is the information of three items of pending product.

[0060] The reservation merchandise information (reservation merchandise N; N is an integer) includes a reservation merchandise type (information indicating whether the reservation merchandise is NON-FILE or read NG) and image data (image data captured when read NG). For example, when the Nth item of merchandise is a reservation merchandise due to NON-FILE, the reservation merchandise information (reservation merchandise N) includes the reservation merchandise type "1 (NON-FILE)" and the image data. Also, when the Nth item of merchandise is a reservation merchandise due to read NG, the reservation merchandise information (reservation merchandise N) includes the reservation merchandise type "2 (read NG)" and the image data.

[0061] Note that instead of or in addition to storing the cart information in the storage unit within its own device, the transaction management server 50 may store part or all of the cart information in another device (such as a file server accessible by the transaction management server 50).

[0062] With reference to FIGS. 9 and 10, the functions of the shopping application installed in the mobile terminal device 40 will be described. When the customer operates the mobile terminal device 40 to start the shopping application, the mobile terminal device 40 on which the shopping application operates first displays a startup screen on the touch panel display unit 406 as shown in FIG. 9(A). On the startup screen in the figure, a "store information" button, a "notification" button, and a "beneficial information" button are arranged. Also, a shopping start button indicating the text "Start shopping" is arranged.

[0063] For example, when the customer performs an operation (tap operation) on the "store information" button, the display on the touch panel display unit 406 transitions to a surrounding store guidance screen as shown in FIG. 9(B). The surrounding store guidance screen displays on the map the stores (usable stores) available for the shopping application that exist within a certain range based on its own position acquired by the position information acquisition unit 409. In the figure, an example is shown where marks indicating three usable stores are arranged on the map based on the current position of the mobile terminal device 40. When displaying such a peripheral store guidance screen, the mobile terminal device 40 transmits a request to search for available stores together with its own location information to, for example, a store information server that manages information on available stores (not shown in the figure, and a transaction management server 50 or the like may be shared as the store information server). In response to receiving the request to search for available stores, the store information server searches for available stores located within a certain distance range based on the location information received together with the request to search for available stores. The store information server transmits the information on the searched available stores to the mobile terminal device 40. The mobile terminal device 40 displays a peripheral store guidance screen using the received information on the available stores.

[0064] The shopping application may have, for example, a shopping list function. The customer can perform an operation of registering the products that he / she intends to purchase in the shopping list. When the shopping application has such a shopping list function in this way, the mobile terminal device 40 includes, for example, information on the products registered in the shopping list in the request to search for available stores. The store information server includes a list of product items sold in the store in the available store information for each store. In response to receiving the request to search for available stores, the store information server includes information indicating the presence or absence of the products registered in the shopping list for each piece of available store information searched as being within a certain range from the location of the mobile terminal device 40, and then transmits the available store information to the mobile terminal device 40. In this case, the mobile terminal device 40 may display the available stores on the map so that the presence or absence of the products registered in the shopping list can be visually recognized. As a display mode of the available stores that enables the presence or absence of the products registered in the shopping list to be visually recognized, for example, for the marks indicating the available stores, the color or size may be changed according to whether the available store has the products registered in the shopping list or not.

[0065] Also, when the customer performs an operation of selecting a mark of an arbitrary store (for example, a tap operation on the mark) while the surrounding store guidance screen is displayed as shown in FIG. 9(B), a store information screen showing the information of the selected store is displayed as shown in FIG. 9(C).

[0066] As described above, in the startup screen of FIG. 9(A), a "Notice" button and a "Beneficial Information" button are arranged. Also, in the store information screen of FIG. 9(C), a "Notice" button and a "Beneficial Information" button are arranged. When the customer operates the "Notice" button while the startup screen or the store information screen is displayed, as shown in FIG. 10(A), an advertisement screen that provides information such as events and sale announcements prepared by the corresponding available store as "Notice" is displayed. Also, when the customer operates the "Beneficial Information" button, as shown in FIG. 10(B), an advertisement screen that provides information on services such as discounts for customers who use the shopping application is displayed. The display of these advertisement screens may be performed based on the advertisement information included in the available store information transmitted from the store information server.

[0067] Also, when the shopping start button arranged on the startup screen of FIG. 9(A) is operated, the touch panel display unit 406 transitions to a product registration screen (code scanning screen) as shown in FIG. 10(C). The customer can perform a product registration operation using the portable terminal device 40 on which the product registration screen is displayed.

[0068] Here, instead of the sales floor where the metering device 10 is arranged, as a basic product registration operation example, an example of a product registration operation in a sales floor where product shelves are arranged will be described. The customer takes out, for example, a product (product to be purchased) that the customer intends to purchase from the product shelf. The customer performs an operation of having the imaging unit 408 of the portable terminal device 40 on which the product registration screen is displayed read the code information of the code (which may be a barcode or a two-dimensional code) attached to the taken-out product to be purchased. The code information read in this way is transmitted from the mobile terminal device 40 to the transaction management server 50 as product registration information corresponding to one product. The transaction management server 50 includes the received product registration information in the cart information (settlement information) corresponding to one transaction. Further, the product registration information based on the read code information may be stored in the mobile terminal device 40. When the customer finishes the registration operation for all the products to be purchased, the customer performs a predetermined operation (product registration completion operation) for instructing the completion of product registration on the mobile terminal device 40. When the product registration completion operation is performed, the mobile terminal device 40 may notify the transaction management server 50 of the completion of product registration. The transaction management server 50 that has received the notification of the completion of product registration can manage the cart information of the corresponding transaction as having completed product registration.

[0069] When the product registration completion operation is performed, a settlement guidance screen is displayed on the touch panel display unit 406 of the mobile terminal device 40 as shown in FIG. 10(D). On the settlement guidance screen in the figure, a guidance message for guiding the customer to go to the settlement device 20 for settlement and transaction code information indicating the transaction corresponding to the current product registration are displayed as, for example, a two-dimensional code. The transaction code information includes a transaction identifier that uniquely indicates the transaction. This transaction identifier may be issued by the transaction management server 50 in response to the mobile terminal device 40 first transmitting product registration information in the corresponding transaction and notified to the mobile terminal device 40. The customer goes to the settlement device 20 and causes the scanner unit 204 of the settlement device 20 to read the two-dimensional code displayed on the settlement guidance screen. The settlement device 20 acquires the cart information corresponding to the transaction identifier indicated by the read two-dimensional code from the transaction management server 50. The settlement device 20 executes a settlement process according to the customer's operation using the acquired cart information. Note that the settlement device 20 may be provided with one or more card readers corresponding to a predetermined card to cope with a case where the customer uses and combines cards such as a credit card, an electronic money card, and a point card for settlement. In this way, in this embodiment, a customer who has installed a shopping application on their own portable terminal device 40 can register products by operating their own portable terminal device 40. Also, the settlement at the settlement device 20 is also performed by the operation of the customer. By performing product registration and settlement by the customer in this way, in this embodiment, it is not necessary for the store clerk to perform operations such as product registration operations and settlement device operations.

[0070] On the other hand, in the store, there is a sales floor for handling weighed goods in a self-service manner where the customer attaches a price to the weighed goods using the weighing device 10 and registers the product. In such a sales floor for handling weighed goods, for the sales floor where the weighing device 10 corresponding to such a self-service method is used, the procedure for product registration and the processing in the sales system associated therewith are different from the case where the basic product registration operation described above is performed. This will be described below.

[0071] First, an example of the procedure for product registration by the customer at the sales floor where the weighing device 10 is used will be described. When the customer intends to purchase a weighed product, first, using their own portable terminal device 40, the customer inputs the item of the product to be purchased as follows. FIG. 11 shows an example of the state in which weighed products are displayed in the store. In the example of the figure, as weighed products, lemons LM, apples AP, and oranges OG are displayed. Also, corresponding to each of the displayed lemons LM, apples AP, and oranges OG, product information panels 3000-LM, 3000-AP, and 3000-OG are installed. When there is no particular distinction between the product information panels 3000-LM, 3000-AP, and 3000-OG, they are referred to as the product information panel 3000.

[0072] The product information panel 3000 presents information about the corresponding product. In the figure, the product information panel 3000-LM is shown enlarged. Thus, in the product information panel 3000-LM, as product information, it is presented that the product item is a lemon, the unit price per unit weight, and the product information code 3001. The product information code 3001 is a barcode (one-dimensional code) in the example of this figure. The product information code 3001 includes the product code of the product item as a lemon. Similarly, in other product information panels 3000, the product item, the unit price per unit weight, and the product information code are presented as product information.

[0073] The product information panel 3000 may be configured to present product information by a display device performing a display. Alternatively, the product information panel 3000 may be configured to present product information by attaching a printed matter such as a poster. When presenting product information by a display device, it can be done at an appropriate timing to display a discount reflected during a time service or the like. Also, by changing and displaying the barcode according to the passage of time, it is possible to prevent fraud such as registering weighed goods at different unit prices by having a barcode or the like previously imaged by a camera read by the portable terminal device 40.

[0074] When entering the product item of the purchase target, the customer causes the product registration screen to be displayed on his / her portable terminal device 40 and has the product information code presented on the product information panel 3000 of the purchase target product read by the portable terminal device 40. In the figure, the state where the customer causes the product information code 3001 corresponding to the lemon LM to be read is shown. In the scan image area AR11 on the product registration screen of the portable terminal device 40, the state of imaging the product information code 3001 is shown. When the product information code 3001 corresponding to the lemon LM is scanned in this way, the mobile terminal device 40 acquires the product information of the lemon LM from the read product information code 3001. The mobile terminal device 40 designates the lemon LM as an item of the weighed product by using the acquired product information.

[0075] Also, on the product registration screen, a product registration status area AR12 is arranged. In the product registration status area AR12, the registration status of the product to be purchased at the current time is shown. In the figure, in the product registration status area AR12, a total area AR121 and registration list items AR122 (AR122-1, AR122-2, AR122-3) are arranged. The registration list item AR122 is a list item that individually shows a registered product or a product in a temporary registration state in which an item has been input. In the figure, as the registration list items AR122, registration list items AR122-1, AR122-2, and AR122-3 corresponding to yogurt, apple AP, and lemon LM are arranged respectively. In this case, yogurt is not a weighed product. Therefore, in the registration list item AR122-1 of yogurt, it is shown that 1 piece has been registered by displaying "×1" in the comment display CM, and the price is shown to be 160 yen. On the other hand, for each of the weighed products of apple AP and lemon LM, the product to be purchased is in a "temporary registration" state (temporary registration state). A product in a temporary registration state is a product for which an item has been input but the pricing has not been completed yet (it is also in a state of waiting for weighing). Therefore, in the registration list items of apple AP and lemon LM, for example, the comment display CM showing "awaiting weighing" indicates that the pricing by weighing has not been performed yet. Accordingly, in the registration list items of apple AP and lemon LM, the display of "?? yen" indicates that the price is undetermined. Also, in the registration list items AR122-1 and AR122-2, a predetermined background color indicating the temporary registration state is set.

[0076] In the example of the figure, the customer has provisionally registered lemons LM and apples AP as weighed goods. In this case, the weighed goods for which the customer has specified items as purchase targets are two types: lemons LM and apples AP. In this case, the customer will weigh each of the lemons LM and apples AP. Therefore, the customer takes out the quantity (number) of each that they intend to purchase from the displayed lemons LM and apples AP. Then, taking the removed lemons LM and apples AP, the customer goes to the weighing and pricing device 10.

[0077] Since the weighing and pricing device 10 where the customer has arrived was in a state where it was not operating in response to the operations of other customers, it was in a standby mode state waiting for the start of weighing corresponding to one transaction. The weighing and pricing device 10 in the standby mode displays an initial state pricing operation screen on the customer display unit 106.

[0078] FIG. 12 shows an example of the initial state pricing operation screen displayed on the customer display unit 106. In the pricing operation screen of the figure, a weighing result area AR31 is arranged. The weighing result area AR31 is an area (column) where the result of weighing the weighed goods to be priced is displayed. The weighing result area AR31 includes a weight area AR31-1, a weight unit price area AR31-2, and a total amount area AR31-3. The weight area AR31-1 is an area where the weight measured for the weighed goods to be priced is shown. The weight unit price area AR31-2 is an area where the weight unit price of the weighed goods to be priced is shown.

[0079] Among the weighed goods, there are those corresponding to the number where the number is calculated based on the measured weight and the unit weight, and the price is calculated based on the calculated number and the unit price per piece. In the case of such weighed goods corresponding to the number, the calculated number based on the measured weight and the unit weight may be displayed in the weight area AR31-1, and the unit price per piece may be shown in the weight unit price area AR31-2. The total amount area AR31-3 is an area where the total amount obtained by summing up the prices of weighed and sold goods for which pricing has been completed under the same single transaction is shown.

[0080] The product selection area AR32 is an area where products to be priced can be selected. In the product selection area AR32 of the figure, four tabs TB (TB-1 to TB-4) are arranged in the product selection area AR32. In the product selection area AR32, a sheet on which product buttons are arranged is associated with each tab TB. The tab TB can be selected by the operation of the customer. The selected tab TB is highlighted with respect to other tabs TB, and in the product selection area AR32, the product button BT1 arranged on the sheet of the selected tab TB is displayed.

[0081] In the example of the figure, on the sheet corresponding to the tab TB-1, the product button BT1 of the provisionally registered product is arranged. On the sheet corresponding to the tab TB-2, product buttons BT1 (preset keys) for each product registered in advance in the product master according to the classification of weighed and sold goods are arranged in a predetermined order. On the sheet corresponding to the tab TB-3, product buttons for products classified as fruits are arranged based on the classification of weighed and sold goods in the product master. The tab corresponding to the sheet TB-4 is a tab corresponding to a sheet on which product buttons for products classified as vegetables are arranged based on the classification of weighed and sold goods in the product master. In this case, among the weighed and sold goods, sheets for fruits and vegetables are prepared in response to the high purchase record of fruits and vegetables.

[0082] On the pricing operation screen in the initial state, as shown in the figure, the tab TB-2 is selected. As a result, in the product selection area AR32, the product buttons BT1 for all products included in all products registered in the product master according to the classification of weighed and sold goods are arranged on the sheet corresponding to the tab TB-2. In this case, the arrangement order of the product buttons BT1 on the sheet may be determined based on, for example, purchase records or preset priorities. Also, in the product selection area AR32 of the figure, 16 product buttons BT1 are arranged. That is, 16 weighed products are presented as selection candidates. When there are 17 or more products registered in the classification of weighed products, for example, by operating page feed or scroll for the area of the sheet, the product buttons BT1 of other weighed products can be displayed. In the figure, the product information on the product buttons BT1 is shown in a simplified manner such as "Item1" and "Item2". However, for example, the product name, pattern, etc. indicating the corresponding product may be displayed on the product buttons BT1. The sheet corresponding to the tab TB-2 is an area for performing an operation of designating (selecting) a product to be priced from all the products classified as weighed products by the product master.

[0083] The sheet corresponding to the tab TB-2 is an area where a customer who prices weighed products without using the mobile terminal device 40 performs an operation of selecting a weighed product to be priced. In the case of a customer who prices weighed products without using the mobile terminal device 40, the information of the weighed products temporarily registered from the mobile terminal device 40 cannot be obtained. In this case, the customer finds the product button BT1 corresponding to the weighed product to be purchased taken from the place where the weighed products are displayed from the sheet corresponding to the tab TB-2 and operates the found product button BT1. At this time, a customer who does not use the mobile terminal device 40 for product registration is made to specify the item of the product to be priced by operating the product button BT1 on the sheet of the tab TB-2.

[0084] When the weighed and sold item to be purchased is fruit, a customer who does not use the mobile terminal device 40 for product registration can operate the tab TB-3 to display a sheet on which the product button BT1 for the weighed and sold item of fruit classification is arranged. The customer can operate the product button BT1 corresponding to the weighed and sold item to be purchased from among the product buttons BT1 arranged on the displayed sheet and specify it as the item of the product to be priced. Also, when the weighed and sold item to be purchased is vegetables, a customer who does not use the mobile terminal device 40 for product registration can operate the tab TB-4 to display a sheet on which the product button BT1 for the weighed and sold item of vegetable classification is arranged. The customer can operate the product button BT1 corresponding to the weighed and sold item to be purchased from among the product buttons BT1 arranged on the displayed sheet and specify it as the item of the product to be priced.

[0085] Also, an upper side in the product selection area AR32, a message area ARm is arranged. The message area ARm is an area where a message of a predetermined content according to the content of the current screen is displayed. In the message area ARm of the figure, "Select The Item" is displayed. That is, in the message area ARm in this case, a message is displayed to guide the customer to operate the product button BT1 for specifying the item of the product to be priced.

[0086] Also, in the pricing operation screen, a connection information code area AR34 is arranged. The connection information code area AR34 is an area where the connection information code CD is displayed. The connection information code may be displayed, for example, as a two-dimensional code. The connection information code is control information indicating procedures for the mobile terminal device 40 on which the shopping application operates to connect to the weighing and pricing device 10, for example, by Bluetooth. In the connection information code area AR34, a message display is performed to guide the customer to read the connection information code CD with the mobile terminal device 40.

[0087] In addition, on the pricing operation screen, a search area AR33 for weighed and sold goods is arranged, which can be searched by character input operation. In the example of the figure, by operating the software keyboard arranged in the search area AR33 to input the product name or the like, it is possible to search for weighed and sold goods. Note that the search area AR33 may not be arranged on the pricing operation screen. Moreover, for example, the search area AR33 may be displayed in response to a predetermined operation on the pricing operation screen.

[0088] A customer who uses the mobile terminal device 40 for product registration, when starting the registration of the weighed and sold goods to be purchased, performs an operation to have the connection information code CD displayed in the connection information code area AR34 read by the mobile terminal device 40.

[0089] In response to reading the connection information code CD as described above, the mobile terminal device 40 establishes communication with the weighing and pricing device 10. When the weighing and pricing device 10 and the mobile terminal device 40 are communicably connected in this way, the weighing and pricing device 10 enters a state in which communication is monopolized by the connected mobile terminal device 40. In a state where communication is monopolized, the mobile terminal device 40 does not connect to other mobile terminal devices 40.

[0090] In addition, when a customer who does not use the mobile terminal device 40 for product registration starts weighing, for example, by placing a product on the weighing platform 109b, the weighing and pricing device 10 may prohibit the establishment of mutual communication with the mobile terminal device 40 thereafter. If the establishment of mutual communication is not prohibited, even if an attempt is made to establish mutual communication, it will end in failure, but it will take time until timeout, so it will take time from detecting the above declaration until actual weighing becomes possible. On the other hand, if the establishment of mutual communication is prohibited, unnecessary time (time until timeout) can be saved, and weighing can be performed immediately. Note that, for example, the above prohibition may be released after the printing of the label is completed.

[0091] When the establishment of mutual communication with the mobile terminal device 40 is prohibited as described above, the metering device 10 may erase the display of the previous connection information code CD. In this case, in the connection information code area AR34 where the connection information code CD has been erased, a display indicating that the establishment of communication with the mobile terminal device 40 is currently prohibited may be made. Alternatively, by at least graying out or the like the location of the connection information code CD in the connection information code area AR34, it may be configured to indicate that the establishment of communication with the mobile terminal device 40 is currently prohibited.

[0092] In response to the establishment of communication with the metering device 10, the mobile terminal device 40 transmits information on the weighed and sold goods in the provisional registration state to the metering device 10. Specifically, in this case, the mobile terminal device 40 transmits information on the lemon LM and the apple AP as information on the weighed and sold goods in the provisional registration state.

[0093] In response to receiving information on the weighed and sold goods in the provisional registration state, the metering device 10 changes the pricing operation screen to the mode shown in FIGS. 12 to 13. In FIG. 13, the same parts as in FIG. 12 are denoted by the same reference numerals and the description thereof is omitted as appropriate.

[0094] In the product selection area AR32 of the pricing operation screen in FIG. 13, the tab TB-1 is in a selected state instead of the tab TB-1 selected in FIG. 12. On the sheet corresponding to the selected tab TB-1, two product buttons BT1 corresponding to the apple AP and the lemon LM are arranged. The weighed and sold products of the apple AP and the lemon LM corresponding to the two product buttons BT1 are the products provisionally registered as described in FIG. 11 above. That is, based on the information on the weighed and sold goods in the provisional registration state received from the mobile terminal device 40, the mobile terminal device 40 causes the product buttons BT1 of the weighed and sold goods in the provisional registration state in the product selection area AR32 to be displayed on the sheet corresponding to the tab TB-1. The arrangement order of the product buttons BT1 in this case may correspond to the provisional registration order (the reading order of the product information codes).

[0095] That is, when the connection with the mobile terminal device 40 is established in the standby mode, the weighing device 10 receives information on the prepackaged goods (pre-registered goods) in the provisional registration state. When the weighing device 10 receives the information on the pre-registered goods, if the sheet of tab TB-2 (FIG. 12) is displayed on the initial value-assigning operation screen, it is switched to the display of the sheet of tab TB-1 (FIG. 13) where the product button BT1 of the pre-registered goods is arranged. Such switching of the tab TB can be regarded as emphasizing (prioritizing) and displaying the pre-registered goods from among the goods pre-registered in the product master according to the classification as prepackaged goods.

[0096] Note that the mode of emphasizing (prioritizing) and displaying the pre-registered goods is not limited to the example of switching the sheet as described above. For example, when the weighing device 10 has not received the information on the pre-registered goods, on one sheet, as shown in FIG. 12, a display is made with the product buttons BT1 corresponding to prepackaged goods in general arranged. When the information on the pre-registered goods is received, the weighing device 10 may display by erasing the product buttons BT1 of the goods other than the pre-registered goods among the product buttons BT1 corresponding to prepackaged goods in general on the same sheet and leaving the product buttons BT1 of the pre-registered goods. At this time, the product buttons BT1 of the pre-registered goods may be rearranged so as to be grouped together. Alternatively, when the information on the pre-registered goods is received, the weighing device 10 may display such that the size of the product button BT1 of the pre-registered goods becomes larger than that of the product button BT1 of the goods not in the provisional registration state. Alternatively, when the information on the pre-registered goods is received, the weighing device 10 may display so as to separate the area where the product button BT1 of the pre-registered goods is arranged and the area where the product button BT1 of the goods not being the pre-registered goods is arranged in the product selection area AR32. In addition, the modes of emphasizing the product button BT1 of the provisionally registered product on the same sheet in this way with respect to the product button BT1 of a product not in the provisionally registered state may be appropriately combined.

[0097] In addition, on the valuation operation screen of FIG. 13, in the connection information code area AR34, instead of the connection information code CD being erased, a display of connection correspondence information indicating that the weighing and valuation device 10 is currently connected to the mobile terminal device 40, such as "Connected", is performed.

[0098] By displaying the connection correspondence information in such a connection information code area AR34, the customer can confirm that as a result of communication between their own mobile terminal device 40 and the weighing and valuation device 10, the display has transitioned to the product selection area AR32 in the figure. Also, for example, when the customer is away from the weighing and valuation device 10 for some reason and another customer tries to use the weighing and valuation device 10, such a situation may occur. Even in such a situation, by looking at the display of the connection correspondence information, other customers can grasp that the weighing and valuation device 10 is in use by a customer other than themselves.

[0099] In addition, in the message area ARm in the figure, a message is displayed to guide the customer to perform an operation on the product button BT1 to specify the item of the product to be valued.

[0100] Note that the display mode of the connection correspondence information may be a mode other than the above display of "Connected". Examples of the connection correspondence information include a terminal number, a member number, a member registration name, a handle name, a character, an arrangement number, a background color setting of the valuation operation screen, and the connection elapsed time with the mobile terminal device 40. The terminal number is a number assigned to the connected mobile terminal device 40. Since the terminal number and the customer uniquely correspond to each other in the store, the terminal number can be treated as information indicating the customer. The membership number is a number assigned to the user (member) of the shopping application installed on the connected mobile terminal device 40. The membership registration name, handle name, etc. are names registered by the user (member) of the shopping application installed on the connected mobile terminal device 40. The character is displayed as an image such as an icon, for example, for dealing with customers. By displaying the character, it indicates that the weighing and pricing device 10 and the mobile terminal device 40 are connected and that it is in the process of dealing with a customer who is pricing the provisionally registered product. The character for dealing with customers may be selected, for example, when the customer registers as a member using the shopping application. Alternatively, the character for dealing with customers may be assigned to customers in order from among a predetermined number of types prepared in advance, for example, by storing them in the weighing and pricing device 10 in advance. The sorting number is, for example, a number assigned to a customer waiting for pricing using the weighing and pricing device 10. As the background color setting of the pricing operation screen, for example, it is changed to a background color different from when it is not connected, in response to being connected to the mobile terminal device 40. Also, a predetermined color may be associated with each customer for the background color after the change (it may be allowed that the same color is associated among certain customers). The background color corresponding to the customer may be selected and set, for example, when the customer registers as a member using the shopping application. Alternatively, the background color corresponding to the customer may be assigned to customers in order from among a predetermined number of colors prepared in advance, for example, by storing them in the weighing and pricing device 10 in advance. The connection elapsed time is the elapsed time since being connected to the mobile terminal device 40. Such an elapsed time indicates the elapsed time during which the customer using the mobile terminal device 40 exclusively occupies the weighing and pricing device 10 for pricing. By also displaying such connection correspondence information, the customer can confirm that their mobile terminal device 40 and the weighing and pricing device 10 are connected. Also, other customers can grasp that the weighing and pricing device 10 is being used by a customer other than themselves.

[0101] Also, in a state where the metering device 10 and the mobile terminal device 40 are connected, the mobile terminal device 40 may also display predetermined connection correspondence information. As the display of the connection correspondence information performed on the mobile terminal device 40, for example, in addition to simply indicating that it is connected, the number attached to the connected metering device 10, the type of the connected metering device 10, etc. may be displayed. By performing such a display, the customer can confirm whether or not it is connected to the metering device 10 by looking at the display of his / her mobile terminal device 40. Also, when a plurality of metering devices 10 are installed, it is possible to confirm which metering device 10 it is connected to based on the displayed number or the like.

[0102] On the mobile terminal device 40 as well, a value attachment operation screen similar to that displayed on the metering device 10 may be displayed. Thereby, the customer can perform the operation of attaching a value to a temporarily registered product and registering it on either the mobile terminal device 40 or the metering device 10.

[0103] Also, on the mobile terminal device 40, the value attachment operation screen may not be displayed. In this case, for example, a product registration screen or the like may be displayed on the mobile terminal device 40. In this case, the customer will perform all operations related to value attachment on the metering device 10. Therefore, in this case, the mobile terminal device 40 may be configured to display, for example, a message such as "Currently communicating with the metering device. Please operate the metering device" in response to being connected to the metering device 10 by reading the connection information code CD. Also, such a display may be performed until the mobile terminal device 40 receives the product value attachment information in which the value attachment processing result is reflected.

[0104] In the following description, an example will be given where the customer operates the value attachment operation screen displayed on the metering device 10 to perform registration. Here, the customer first decided to register the apple AP in the provisional registration state among the apple AP and the lemon LM. Therefore, the customer operated the product button BT1 corresponding to the apple AP. As a result, the apple AP is designated as the object to be priced.

[0105] In response to the apple AP being designated as the object to be priced, the display on the customer display unit 106 in the weighing and pricing device 10 transitions from the pricing operation screen to the weighing guidance screen. FIG. 14 shows an example of the weighing guidance screen. In the weighing guidance screen of the figure, the same parts as those in the pricing operation screens of FIGS. 12 and 13 are denoted by the same reference numerals. In the weighing guidance screen, instead of the product selection area AR32 arranged in the pricing operation screen, a weighing guidance area AR36 is arranged. In the weighing guidance area AR36 of the figure, the characters "apple" and the picture of an apple are displayed. Also, in the weighing guidance area AR36, a message area ARm is arranged. In the message area ARm of the weighing guidance area AR36, a message is displayed to guide the customer to place the apple AP on the weighing platform 109b, such as "PLACE ITEM". With such a display, the customer can confirm that the product button BT1 they operated corresponds to the apple AP without mistake. Also, the customer can understand that they should place the apple AP, which is the weighed and sold product to be purchased, on the weighing platform 109b.

[0106] When the weighing guidance screen of the figure is being displayed, the apple AP designated as the object to be priced is in a state where it has not yet been placed on the weighing platform 109b. Before placing the apple AP on the weighing platform 109b in this way, the display in the weighing result area AR31 of the pricing operation screen is in the following state. That is, the weight area AR31-1 indicates that the weight is zero in response to the fact that weighing has not been performed yet. The unit price per weight area AR31-2 indicates the unit price per weight of the apple AP designated as the pricing target. The unit price per weight displayed in this way may be obtained from the product information of the apple AP in the product master, for example. The total amount area AR31-3 indicates that the price is zero. The content before weighing displayed in the weighing result area AR31 of the pricing operation screen in this way is also included in the weighing result shown in the weighing result area AR31.

[0107] Also, in the weighing guidance area AR36, a return button BT14 and a stop button BT15 are arranged. The return button BT14 is a button for performing an operation to return to the previous screen. The stop button BT15 is a button for performing an operation to instruct the cancellation of the weighing and registration by pricing of the semi-registered weighed and sold product. If the customer operates the stop button BT12 at this time, the semi-registered state of the apple AP is cancelled. In this case, the customer may return the apple AP brought from the display location to the display location, or keep it as a reserved product and hand it over to the store clerk at the time of settlement.

[0108] Also, under the state where the weighing guidance screen is displayed, the connection between the weighing and pricing device 10 and the mobile terminal device 40 is continued. Along with this, in the weighing guidance screen of the figure, following the pricing operation screen of FIG. 13, a connection information code area AR34 where connection notification is displayed is arranged.

[0109] In the state where the weighing guidance screen of the figure is displayed, the customer places the apple AP to be priced on the weighing platform 109b. In response to the apple AP being placed on the weighing platform 109b, the weighing and pricing device 10 executes a pricing process. That is, the weighing and pricing device 10 determines the weight of the apple AP when it determines that the weight of the apple AP measured by the weighing unit 109 has stabilized, and calculates the price based on the determined weight and the unit price per weight.

[0110] In response to the pricing process being executed in this way, the display on the customer display unit 106 transitions from the weighing guidance screen in FIG. 14 to the weighing result screen. FIG. 15 shows an example of the weighing result screen. In the figure, the same parts as those in FIG. 14 are denoted by the same reference numerals, and the description thereof will be omitted as appropriate. On the weighing result screen in the figure, in the weighing result area AR31, the weight of the apple AP measured in the weight area AR31-1 is shown, and in the total amount area AR31-3, the total amount corresponding to the calculated price of the apple AP is shown, and the state has changed. Also, in the weighing guidance area AR36, a label issuance button BT16 is arranged. Also, in the message area ARm, a message prompting the customer to operate the label issuance button BT16 for issuing a label (single-item label) reflecting the pricing result of the apple AP, such as "PRINT LABEL", is displayed.

[0111] In this case, the customer operates the label issuance button BT16. In this case, the weighing and pricing device 10 finalizes the pricing by the pricing process in response to the operation of the label issuance button BT16, and issues a label (single-item label) on which the content reflecting the finalized pricing result for the apple AP is printed. The operation on the label issuance button BT16 on such a weighing result screen is also a confirmation operation by the customer regarding the pricing results such as the weight and price displayed in the weighing result area AR31.

[0112] In response to an operation being performed on the label issuance button BT16, the weighing and labeling device 10 transmits merchandise valuation information about the apple AP to the connected mobile terminal device 40 along with the issuance of the label. That is, in this case, the operation on the label issuance button BT16 serves as a trigger for instructing two processes: the issuance of the label and the transmission of the merchandise valuation information.

[0113] Note that the weighing result screen may be configured such that the label issuance button BT16 is not arranged thereon. In this case, the weighing and labeling device 10 may issue a label and transmit the merchandise valuation information, for example, in response to the weight measured by the weighing unit 109 being determined.

[0114] Also, although not shown in the drawings, after the label is issued, the display may transition from the weighing result screen to the label affixing guidance screen. On the label affixing guidance screen, a message, a pattern, etc. are displayed to guide the customer to affix the label issued from the weighing and labeling device 10 onto the bag containing the apple AP that has been valued this time. The customer is instructed to lift the apple AP from the weighing platform 109b and affix the label taken out from the label outlet 110a onto the bag containing the apple AP. The label affixing guidance screen is erased, for example, in response to a sensor provided at the label outlet 110a detecting that the label has been taken out. Instead of erasing the label affixing guidance screen, the customer display unit 106 transitions to the display of a valuation operation screen for specifying the item of the next weighed and sold merchandise to be valued. However, when a weight object is still placed on the weighing platform 109b, for example, at the timing when the label is taken out from the label outlet 110a, a screen is displayed to guide the customer to remove the weight object on the weighing platform 109b.

[0115] As described above, when a valuation result is obtained for the weighed and sold merchandise in the provisional registration state and the label is issued, the weighing and labeling device 10 transmits the merchandise registration information of the apple AP in which the valuation result is reflected to the mobile terminal device 40. Note that the metering and labeling device 10 may transmit the product registration information to the transaction management server 50 via a communication line.

[0116] FIG. 16 shows a pricing operation screen that is displayed instead of the label affixing guidance screen in response to the issuance of a label for the Apple AP. On the pricing operation screen in the figure, the product button BT1 for the Apple AP that was displayed on the pricing operation screen in FIG. 13 is grayed out and disabled. Note that the product button BT-1 for the Apple AP may be deleted instead of being grayed out. That is, the product selection area AR32 on the pricing operation screen is enabled only for operations on the weighed and sold products in the provisional registration state. Also, when the pricing operation screen in the figure is displayed, a pricing operation screen that allows the same operations as those in the figure may also be displayed on the mobile terminal device 40.

[0117] In the state where the pricing operation screen in the figure is displayed, the customer operates the product button BT1 for the lemon LM in order to price the lemon LM, which is still in the provisional registration state.

[0118] After the customer operates the product button BT11-2 corresponding to the lemon LM, the metering and labeling device 10 is made to perform the pricing process and label issuance for the lemon LM in the same procedure as the Apple AP described above. In response to the issuance of a label for the lemon LM, it means that the pricing process (registration) for all the weighed and sold products in the provisional registration state has been completed.

[0119] In response to the completion of the registration for all the weighed and sold products in the provisional registration state, the display on the customer display unit 106 of the metering and labeling device 10 is set to return to the initial pricing operation screen (FIG. 12).

[0120] Also, in response to the completion of the registration for all the weighed and sold products in the provisional registration state, the product registration screen displayed on the touch panel display unit 406 of the mobile terminal device 40 becomes, for example, the state shown in FIG. 17. In the product registration status area AR12 of the product registration screen in the figure, compared with FIG. 11, the following changes have occurred. That is, the registration list items AR122-1 and AR122-2 corresponding to the lemon LM and the apple AP have changed from the state indicating provisional registration to the state indicating registered. Specifically, the background color in each of the registration list items AR122-1 and AR122-2 has changed from the color indicating the provisional registration state to the color indicating registered. Also, the price determined by the valuation process is shown in each of the registration list items AR122-1 and AR122-2. Further, the comment display CM in each of the registration list items AR122-1 and AR122-2 has changed from "quantity measurement required" to "quantity measured". The comment display CM of "quantity measured" indicates that the corresponding product is a weighed and sold product and has been registered by the processes of weighing and valuation. Therefore, the comment display CM may be, for example, a display such as "quantity measured" or "registered" instead of the display of "quantity measured". Also, in the product registration status area AR12, for the weighed and sold products that have been weighed, information regarding the results of valuation processes such as the weighed weight, price, unit price, etc. may be displayed. Alternatively, in response to the corresponding product being registered, the "quantity measurement required" comment display CM itself may be deleted. Even in such a case, in the product registration status area AR12, it is preferable to change the aspect such as the background color of the registration list item AR122 so that the weighed and sold products and the products that are not weighed and sold products can be visually distinguished.

[0121] Note that the product registration screen displayed on the mobile terminal device 40 may be configured to change to a state indicating that the registration list item AR122 of the weighed and sold product for which the registration has been completed is registered as each registration of a plurality of weighed and sold products in the provisional registration state is completed one by one.

[0122] With reference to the flowchart of FIG. 18, an example of the processing procedure executed by the weighing and valuation device 10, the mobile terminal device 40, and the transaction management server 50 in the present embodiment related to the registration of weighed and sold products in a single transaction will be described.

[0123] First, a processing procedure example of the mobile terminal device 40 corresponding to the case where a customer inputs an item of a weighed and sold product to be purchased using the mobile terminal device 40 will be described. Step S2201: The mobile terminal device 40 waits for the reading of the product information code 3001 (Fig. 11) while the product registration screen is being displayed on the display unit 406 with a touch panel.

[0124] Step S2202: In response to the reading of the product information code 3001, the mobile terminal device 40 acquires product information from the read product information code. By acquiring the product information, the mobile terminal device 40 is considered to have input the item of the product to be purchased by the customer.

[0125] Step S2203: The mobile terminal device 40 adds a registration list item AR122 indicating the product of the product information acquired in Step S2202 to the product registration status area AR12 of the product registration screen. The product of the product information acquired in response to the reading of the product information code 3001 is treated as a temporarily registered product in this way. The registration list item AR122 of the temporarily registered product is set with a background color indicating temporary registration, like the registration list items AR122-2 and AR122-3 in Fig. 11, and in the comment display CM, it is shown that valuation has not been performed yet by displaying "Requires weighing". After the processing of Step S2203, the processing returns to Step S2201.

[0126] Next, a processing procedure example that the weighing and valuation device 10 executes corresponding to the valuation of the temporarily registered product will be described. Step S2101: The weighing and valuation device 10 sets the standby mode in a state where no operation regarding valuation by the customer has been performed (standby state). In the standby mode, the weighing and valuation device 10 displays an initial-state valuation operation screen on the customer display unit 106 as exemplified in Fig. 12. As shown in Fig. 12, a connection information code CD is displayed on the valuation operation screen.

[0127] Step S2102: In the standby state, the metering device 10 determines whether the connection process with the mobile terminal device 40 that has read the connection information code CD has started.

[0128] Step S2103: If it is determined in Step S2102 that the connection process has not started, the metering device 10 determines whether a selection operation of the product to be priced by the customer has been performed. The selection operation of the product to be priced is an operation on the product button BT1 arranged on the sheet corresponding to any of the tabs TB-2, TB-3, and TB-4 arranged in the product selection area AR32 of the pricing operation screen.

[0129] Step S2104: If it is determined that the selection operation of the product to be priced has not been performed, the metering device 10 determines whether the metering unit 109 has started metering when the customer places the product on the weighing platform 109b. If it is determined that the metering unit 109 has not started metering, the process returns to Step S2101.

[0130] Step S2105: If it is determined in Step S2103 that the selection operation of the product to be priced has been performed, or if it is determined in Step S2104 that the metering has started, the metering device 10 performs a pricing process corresponding to a transaction without using the mobile terminal device 40 for the product being metered.

[0131] As the value-assignment process in step S2015 corresponding to a transaction that does not use the mobile terminal device 40, when it is determined in step S2103 that a product selection operation has been performed, the weighing and value-assignment device 10 causes a weighing guidance screen corresponding to the product selected by the product selection operation to be displayed in a manner according to FIG. 14. Also, in the connection information code area AR34 on the weighing guidance screen in this case, the connection information code CD may be erased, and a message such as "Connecting" may not be displayed. Note that the connection information code CD may also be displayed on the weighing guidance screen corresponding to a transaction that does not use the mobile terminal device 40. In this case, the connection information code CD may be displayed until the value-assignment processing result is finalized and the label is issued, or may be erased at a predetermined timing before the value-assignment processing result is finalized and the label is issued.

[0132] The weighing and value-assignment device 10 that has displayed the above-mentioned weighing guidance screen calculates the price of the product to be value-assigned based on the weighing result of the weighing unit 109 in response to the customer placing the product to be value-assigned on the weighing platform 109b. When the price is calculated, the weighing and value-assignment device 10 displays a weighing result screen. Such a weighing result screen is in a manner according to FIG. 15, has content for guiding the customer to perform an operation for issuing a label, and has a label issuance button BT16 arranged thereon.

[0133] The weighing and value-assignment device 10 issues a label (single-item label) in which the value-assignment processing result of the current product to be value-assigned is reflected in response to the label issuance button BT16 being operated. After that, the weighing and value-assignment device 10 returns the processing to step S2101 to display the value-assignment operation screen in the initial state and enter the standby mode. The label issued under the value-assignment process in step S2105 has code information such as a barcode that reflects the value-assignment processing result such as the product item and price of the product. The product value-assigned by the value-assignment process in step S2105 is registered as a product by a POS terminal (not shown) operated by a store clerk who interacts with the customer. The store clerk performs product registration by operating the POS terminal to read the code information on the label.

[0134] Note that the code information of the label may be readable not only by the POS terminal but also by the mobile terminal device 40. Even a customer using the mobile terminal device 40 may, for example, have a possibility that a label with the code information printed thereon is issued by a store clerk by mistake. In this case, the weighing and pricing device 10 will not transmit the product pricing information to the mobile terminal device 40. Even if such a situation occurs, if the code information of the label is read by the mobile terminal device 40, the mobile terminal device 40 can acquire the product pricing information. Note that in this embodiment, even if the code information is printed on the label issued corresponding to the customer using the mobile terminal device 40 in step S2111, there is no particular problem in operations such as settlement. Moreover, in this embodiment, in the case of a customer using the mobile terminal device 40, the mobile terminal device 40 can acquire the product pricing information through communication with the weighing and pricing device 10 without having the code information printed on the label read by the mobile terminal device 40 deliberately.

[0135] Also, as the pricing process in step S2015, when it is determined in step S2104 that weighing has started, the weighing and pricing device 10 waits for an operation of the product button BT1 on the pricing operation screen being displayed at that time. The customer finds the product button BT1 corresponding to the product placed on the weighing platform 109b from the product selection area AR32 of the pricing operation screen and operates the found product button BT1. The weighing and pricing device 10 sets the product corresponding to the operated product button BT1 as the pricing target. When the weighing and pricing device 10 sets the product corresponding to the operated product button BT1 as the pricing target, it calculates the price of the product to be priced based on the weighing result of the weighing unit 109. When the price is calculated, the weighing and pricing device 10 displays a weighing result screen that has content guiding the customer through the label issuance operation and on which a label issuance button BT16 is arranged. When the label issuance button BT16 is operated, the weighing and pricing device 10 issues a label (single-item label) in which the pricing processing result of the item to be priced this time is reflected. After that, the weighing and pricing device 10 returns the processing to step S2101, displays the pricing operation screen in the initial state, and enters the standby mode.

[0136] Step S2106: When it is determined in step S2102 that the connection process has started, the weighing and pricing device 10 executes the started connection process to establish a connection with the mobile terminal device 40.

[0137] Step S2107: When the connection is established, the mobile terminal device 40 transmits provisional registration product information. The weighing and pricing device 10 acquires the transmitted provisional registration product information. The provisional registration product information is a weighed product such as apple AP or lemon LM for which an item has been input in response to the mobile terminal device 40 reading the product information code 3001.

[0138] Step S2108: The weighing and pricing device 10 that has acquired the provisional registration product information displays a pricing operation screen corresponding to the provisional registration product. The pricing operation screen corresponding to the provisional registration product is in the form illustrated in FIG. 13.

[0139] Step S2109: After displaying the pricing operation screen, the weighing and pricing device 10 executes a pricing process in response to the customer's pricing operation. That is, the customer operates the product button BT1 on the pricing operation screen in FIG. 13 to specify the provisional registration product to be the pricing process target. The weighing and pricing device 10 displays a weighing guidance screen in the form illustrated in FIG. 14 in response to the operation of the product button BT1. The customer places the provisional registration product specified as the pricing process target on the weighing platform 109b and causes the weighing unit 109 to perform weighing. The weighing and pricing device 10 calculates the price using the weight measured by the weighing unit 109 and the unit price of the weight shown in the provisional registration product information acquired in step S2107.

[0140] Step S2110: In response to the price being determined by the value assignment process in Step S2109, the weighing and pricing device 10 causes the customer display unit 106 to display a weighing result screen in the form illustrated in FIG. 15. The weighing and pricing device 10 performs display in the weighing result area AR31 of the weighing result screen so that the weighed weight and the calculated price are reflected together with the unit price per weight.

[0141] Step S2111: A label issuance button BT16 is arranged on the weighing result screen. The customer operates the label issuance button BT16. In response to the label issuance button BT16 being operated, the weighing and pricing device 10 issues a label corresponding to the product value-assigned by the value assignment process in the current Step S2018. When the value assignment process in Step S2109 is executed, product value-assignment information is transmitted to the transaction management server 50 in Step S2112 described later. That is, the result of the value assignment process is passed to the transaction management server 50. Therefore, for the label issued in Step S2111, code information reflecting the result of the value assignment process does not necessarily need to be printed.

[0142] Note that, as the process in Step S2111, the weighing and pricing device 10 may be configured to issue a label in response to, for example, the value assignment process in Step S2109 being completed and the price being determined. In this case, the display of the label issuance button BT16 on the weighing result screen may be omitted.

[0143] Step S2112: Further, in response to the value assignment process in Step S2108 being completed and the price being determined, the weighing and pricing device 10 transmits product value-assignment information to the mobile terminal device 40. The product value-assignment information reflects the result of the value assignment process for the product that is the target of the value assignment process in the current Step S2109.

[0144] Step S2113: After transmitting the product value-assignment information in Step S2112, the weighing and pricing device 10 determines whether the value assignment process for all provisionally registered products has been completed. If there are still items for which the pricing process has not been completed, the process returns to step S2108. In this case, the weighing and pricing device 10 displays a pricing operation screen in step S2108 in which the product button BT11 of the provisionally registered product for which the pricing process has been completed is in a non-operable state, as illustrated in FIG. 16.

[0145] Step S2114: If it is determined in step S2113 that the pricing process for all provisionally registered products has been completed, the weighing and pricing device 10 disconnects the connection established with the mobile terminal device 40 in step S2106. After disconnecting the connection with the mobile terminal device 40, the process returns to step S2101, entering the standby mode, and a pricing operation screen in the initial state is displayed.

[0146] Next, a description will be given of an example of the processing procedure executed by the mobile terminal device 40 in relation to the pricing of provisionally registered products. Step S2211: The mobile terminal device 40 waits for the connection information code CD to be read while displaying the product registration screen.

[0147] Step S2212: When the customer performs an operation to have the mobile terminal device 40 read the connection information code CD, the mobile terminal device 40 reads the connection information code CD. In response to the reading of the connection information code CD, the mobile terminal device 40 executes, between itself and the weighing and pricing device 10, processing for establishing a communicable connection with the weighing and pricing device 10 according to the connection procedure indicated by the read connection information code CD.

[0148] Step S2213: When the connection with the weighing and pricing device 10 is established by the connection process in step S2212, the mobile terminal device 40 transmits provisional registration product information to the weighing and pricing device 10. The provisional registration product information is information on the weighed and sold products for which items have been input by the processing in steps S2201 to S2203.

[0149] Step S2214: The mobile terminal device 40 waits for the receipt of the merchandise valuation information transmitted from the weighing and valuing device 10 in step S2211. When the mobile terminal device 40 receives the merchandise valuation information, it transmits the merchandise registration information in which the valuation processing result indicated by the received merchandise valuation information is reflected to the transaction management server 50. Further, the mobile terminal device 40 determines that the valuation of the provisionally registered merchandise indicated by the merchandise valuation information is completed in response to the receipt of the merchandise valuation information.

[0150] Step S2215: After the process of step S2214, the mobile terminal device 40 determines whether the valuation process for all the provisionally registered merchandise is completed. If there are still merchandise for which the valuation process has not been completed, the process returns to step S2214. In this case, the mobile terminal device 40 waits in step S2214 for the receipt of the merchandise valuation information, and when the merchandise valuation information is received, it transmits the merchandise registration information in which the valuation processing result indicated by the received merchandise valuation information is reflected to the transaction management server 50.

[0151] Step S2216: If it is determined in step S2215 that the valuation process for all the provisionally registered merchandise is completed, the mobile terminal device 40 causes the display unit 406 with a touch panel to display a merchandise registration screen.

[0152] Next, an example of the processing procedure executed by the transaction management server 50 will be described. Step S2301: The transaction management server 50 waits for the receipt of the merchandise registration information transmitted from the mobile terminal device 40 in step S2215. Step S2302: When the product registration information is received, the transaction management server 50 registers (adds) the received product registration information to the cart information corresponding to the current transaction. At this time, the transaction management server 50 searches for the cart information associated with the same cart identification information included in the received product registration information, and registers the product registration information in the searched cart information. By performing the process of step S2302, the provisional registration state for one product is cancelled and the registration is completed. After the process of step S2302, the process returns to step S2301.

[0153] <Modification Example> Hereinafter, a modification example of the present embodiment will be described.

[0154] [First Modification Example] For example, when purchasing a weighed product without using the mobile terminal device 40, the input of the item of the product to be priced may be performed as follows. At the display location of the weighed product, a tag device may be arranged corresponding to each displayed weighed product. The tag device is communicably connected to the weighing and pricing device 10 by wire or wirelessly. Further, the tag device stores product information indicating the corresponding weighed product. The tag device can detect being touched by a touch operation by including a touch sensor. In this case, the customer performs a touch operation on the tag device of the weighed product to be purchased by the customer himself / herself. The tag device that has detected the touch operation transmits the product information stored in itself to the weighing and pricing device 10.

[0155] The weighing and pricing device 10 of this modification example displays a sheet of the "My Item" tab TB-1 in which product buttons BT1 corresponding to the product information received from the tag device are arranged in the product selection area AR32 of the pricing operation screen displayed corresponding to the standby mode. Here, for example, when no product information is received from the tag device in the standby mode, the weighing and pricing device 10 of this modification example may display, as shown in FIG. 12, a sheet of the "POPULAR" tab TB-2 on which product buttons BT1 of products registered in the product master by classification of weighed and sold products are arranged in the product selection area AR32. Moreover, the weighing and pricing device 10 may be configured to switch to the display of the sheet of the "My Item" tab TB-1 on which the product button BT1 corresponding to the product information transmitted from the tag device is arranged in response to receiving the product information from the tag device.

[0156] By performing such a display, for example, when a customer who does not use the portable terminal device 40 visits the weighing and pricing device 10, the product button BT1 of the product that the customer has touched the tag device to input as the purchase target is in a displayed state. As a result, the customer can immediately find and operate the product button BT1 of the product that the customer wants to price.

[0157] Also, for example, a customer who can use the portable terminal device 40 may forget this and input the item of the product to be priced by a touch operation on the tag device, but may remember that the portable terminal device 40 can be used when visiting the weighing and pricing device 10. In such a case, before operating the product button BT1, for example, the customer may cause the portable terminal device 40 to read the connection information code CD and connect the portable terminal device 40 and the weighing and pricing device 10. In this case, the weighing and pricing device 10 is notified from the portable terminal device 40 that there is no temporarily registered product information. When receiving such a notification, the weighing and pricing device 10 may handle the product button BT1 arranged on the sheet corresponding to the "My Item" tab TB-1 of the pricing operation screen as the product button BT1 corresponding to the temporarily registered product, and execute the subsequent pricing process. Alternatively, as described with reference to FIG. 11, without providing the product information panel 3000 at the location where the products are displayed, the customer may be asked to perform a touch operation on the tag device regardless of whether the customer purchases the weighed products using the mobile terminal device 40. When purchasing the weighed products using the mobile terminal device 40, before operating the product button BT1 as described above, the customer causes the mobile terminal device 40 to read the connection information code CD to connect the mobile terminal device 40 and the weighing device 10.

[0158] [Second Modified Example] Also, the input of the item of the product to be priced may be performed as follows. In this modified example, a motion sensor for detecting motion is provided at a part such as a lid or a lever that moves as the product is taken out of the furniture in which the weighed products are stored. The detection of the motion by the motion sensor can be realized by, for example, an acceleration sensor or the like, and stores product information indicating the corresponding weighed product. The motion sensor transmits the product information stored by itself to the weighing device 10 in response to detecting the motion. In this case, the customer takes out the product to be purchased from the displayed products. In response to the product being taken out, the motion sensor corresponding to the product to be purchased detects the motion. The motion sensor transmits the product information stored by itself to the weighing device 10 in response to detecting the motion.

[0159] The weighing device 10 of this modified example displays a sheet of the "My Item" tab TB-1 in which product buttons BT1 corresponding to the product information received from the motion sensor are arranged in the product selection area AR32 of the pricing operation screen displayed corresponding to the standby mode. Also in this modification example, when no product information is received from the motion sensor in the weighing device 10, for example, in the standby mode, in the product selection area AR32, a sheet of the "POPULAR" tab TB-2 on which the product button BT1 of the product registered in the product master according to the classification of the weighed products is arranged may be displayed. Moreover, the weighing device 10 may be configured to switch to the display of the sheet of the "My Item" tab TB-1 on which the product button BT1 corresponding to the product information transmitted from the motion sensor is arranged in response to the reception of the product information from the motion sensor.

[0160] In this modification example, a customer who does not use the mobile terminal device 40 may directly operate the product button BT1 on the sheet of the tab TB-1 displayed on the weighing device 10 to specify the product to be priced. On the other hand, a customer who uses the mobile terminal device 40 causes the mobile terminal device 40 to read the connection information code CD displayed on the weighing screen before operating the product button BT1, and connects the mobile terminal device 40 and the weighing device 10. In this case, the weighing device 10 treats the product button BT1 arranged on the sheet corresponding to the "My Item" tab TB-1 of the pricing operation screen as the product button BT1 corresponding to the temporarily registered product, and executes the subsequent pricing process. In the operation of this modification example, it is not necessary to provide the product information panel 3000 at the place where the products are displayed as shown in FIG. 11.

[0161] [Third Modification Example] In the sixth embodiment, the acquisition of the product information (temporarily registered product information) of the product to be priced (temporarily registered product) by the weighing device 10 is not limited to the reception of the temporarily registered product information transmitted from the mobile terminal device 40. For example, the weighing device 10 can display a product selection screen on the customer display unit 106 with preset keys corresponding to each weighed product arranged. The product selection screen may be in a form in which product buttons BT1 of products registered in advance as weighed products are arranged, like the sheet of the tab TB-2 in FIG. 12. The customer can specify the product to be priced by the weighing and pricing device 10 by operating the preset key arranged on the displayed product selection screen. The weighing and pricing device 10 may be configured to acquire the product information of the product corresponding to the operated preset key as temporarily registered product information. In this case, it is not necessary to transmit the product information of the product to be priced from the mobile terminal device 40 to the weighing and pricing device 10. Therefore, in this case, the weighing and pricing device 10 may not display the connection information code CD on the standby screen, but may display the connection information code CD on the customer display unit 106 at a predetermined timing according to, for example, the operation of the preset key. For example, the weighing and pricing device 10 may display the connection information code CD at the timing when the product selection screen on which the preset key is arranged is displayed. Alternatively, the weighing and pricing device 10 may display the connection information code CD at a predetermined timing from the operation of the preset key for selecting the first temporarily registered product until the operation of the preset key for selecting the last temporarily registered product is performed. Alternatively, the weighing and pricing device 10 may display the connection information code CD at the timing when the operation of the preset key corresponding to all the weighed and sold products to be purchased is completed. Alternatively, the weighing and pricing device 10 may display the connection information code CD at the timing when at least one product has been priced after the operation of the preset key corresponding to all the weighed and sold products to be purchased is completed.

[0162] When the mobile terminal device 40 reads the connection information code CD and is communicably connected to the weighing and pricing device 10, the temporarily registered product information can be transmitted from the weighing and pricing device 10 to the mobile terminal device 40. Thereby, the temporarily registered product information can be shared between the weighing and pricing device 10 and the mobile terminal device 40. Also, the connection information code CD may be erased at the timing when the connection between the weighing and pricing device 10 and the mobile terminal device 40 is established. Alternatively, the connection information code CD may be erased at a timing corresponding to, for example, the completion of pricing of all the temporarily registered products.

[0163] Further, for example, the metering device 10 is provided with an imaging unit that images the product to be valued. Based on the analysis result of the image obtained by the imaging unit imaging the weighed and sold product that the customer intends to purchase, the metering device 10 identifies the item of the product. The metering device 10 may be configured to obtain temporary registration product information by obtaining product information corresponding to the identified item from, for example, a product master or the like. Also in this case, for example, the transaction management server 50 may receive the image of the product that has been imaged from the metering device 10, analyze the received image to identify the item of the product to be valued, and notify the metering device 10 of the identified item of the product from the transaction management server 50. In this case, the metering device 10 may display the connection information code CD at a predetermined timing from when the temporary registration product information of the first product is obtained until the temporary registration product information of the last product is obtained. Alternatively, the connection information code CD may be displayed at the timing when the temporary registration product information corresponding to all of the weighed and sold products to be purchased is obtained. Also, the erasure of the connection information code CD in this case may be performed at the timing when the connection between the metering device 10 and the mobile terminal device 40 is established, or at the timing corresponding to the completion of the valuation of all the temporarily registered products.

[0164] Further, for example, a tag device may be arranged at a position corresponding to the customer side for each of the displayed weighed and sold products. The tag device is communicably connected to the metering device 10 by wire or wirelessly. The tag device stores product information indicating the corresponding weighed and sold product. The tag device can detect being touched by a touch operation by including a touch sensor. In this case, the customer performs a touch operation on the tag device corresponding to the product to be purchased. The tag device that has detected the touch operation transmits the product information it stores to the metering device 10. The metering device 10 may be configured to obtain the received product information as temporary registration product information. In this case, the metering device 10 may display the connection information code CD, for example, at the timing when the temporary registration product information of the first product is obtained. Also, the erasure of the connection information code CD in this case may also be performed at the timing when the connection between the metering device 10 and the mobile terminal device 40 is established, or at the timing corresponding to the completion of the pricing of all provisionally registered products, etc.

[0165] Further, a motion sensor for detecting motion may be provided at a part such as a lid or a lever that moves as a customer takes out a product from a furniture in which the weighed products are stored. Detection of the motion by the motion sensor can be realized by, for example, an acceleration sensor or the like, and also stores product information indicating the corresponding weighed product. The motion sensor transmits the product information stored by itself to the metering device 10 in response to detecting the motion. In this case, the customer takes out the product to be purchased from among the displayed products. In response to the product being taken out, the motion sensor corresponding to the product to be purchased detects the motion. The motion sensor transmits the product information stored by itself to the metering device 10 in response to detecting the motion. The metering device 10 acquires the received product information as provisionally registered product information. In this case, the metering device 10 may also display the connection information code CD, for example, at the timing when the provisionally registered product information of the first product is acquired. Also, the erasure of the connection information code CD in this case may also be performed at the timing when the connection between the metering device 10 and the mobile terminal device 40 is established, or at the timing corresponding to the completion of the pricing of all provisionally registered products, etc.

[0166] [Fourth Modification Example] Further, as a modification of the present embodiment, corresponding to customers who use the mobile terminal device 40 and customers who do not use it, product pricing may be enabled in the following procedure. In this modified example, the weighing and pricing device 10 displays a standby screen in the standby mode. The weighing and pricing device 10 cyclically switches and displays a plurality of standby screens, for example, at predetermined time intervals. For example, one of the standby screens has content guiding the customer to place the product on the weighing platform 109b for the start of pricing. Also, one of the standby screens has content guiding the customer to read the code information (e.g., barcode) attached to the product. Further, one of the standby screens has content guiding the customer to perform an operation of searching for the product for the start of pricing. Additionally, one of the standby screens has content guiding the customer to perform an operation of touching the standby screen for the start of pricing.

[0167] In this modified example, the product information panel 3000 used in the sixth embodiment is not used at the product display location. For this reason, a customer using the portable terminal device 40 does not perform temporary registration by reading the product information code 3001 of the product information panel 3000 for input of the item of the product to be priced. In this modified example, regardless of whether the customer uses the portable terminal device 40 or not, the customer is made to perform input (preliminary item input) of the item of the product to be priced by performing a touch operation on the tag device corresponding to the product to be purchased, which was described in the first or second modified example above, or by taking out the product to be purchased from the display location equipped with the motion sensor. Alternatively, regardless of whether the customer uses the portable terminal device 40 or not, first the customer takes out the product to be purchased from the product display location and then performs a product selection operation on the weighing and pricing device 10, thereby performing input (screen operation item input) of the item of the product to be priced.

[0168] The weighing and pricing device 10 of this modified example sets the standby mode when it is not operating in response to the customer's operation. The weighing and pricing device 10 in the standby mode displays an initial-state pricing operation screen on the customer display unit 106. The initial-state pricing operation screen may be in the same manner as in FIG. 12.

[0169] In the standby mode, when the weighing and labeling device 10 receives information on prepackaged items in response to a pre-item input from a tag device or a motion sensor, instead of the value-assigning operation screen in the above-described initial state, a value-assigning operation screen in a state where the tab TB-1 is selected in the product selection area AR32 is displayed in the same manner as in FIG. 13.

[0170] As described above, in the standby mode, by default, the weighing and labeling device 10 in this modification arranges product buttons BT1 of products registered in the classification of prepackaged items on the sheet with the tab TB-2 selected in the product selection area AR32. In this state, when a pre-item input is made by the customer and information on the prepackaged item transmitted from outside the weighing device (tag device or motion sensor) is received, the weighing and labeling device 10 changes to a state where the tab TB-1 is selected from the tab TB-2. The weighing and labeling device 10 performs a display for arranging product buttons BT1 corresponding to the received information on the prepackaged item on the sheet of the selected tab TB-1. Then, after that, when the customer makes the next pre-item input and another piece of information on the prepackaged item is received, the weighing and labeling device 10 performs a display for additionally arranging product buttons BT1 corresponding to the received information on the prepackaged item on the sheet of the tab TB-1.

[0171] When the customer arrives at the weighing and labeling device 10 without making a pre-item input, a value-assigning operation screen in which product buttons BT1 as preset keys are arranged on the sheet of the tab TB-2 is displayed in the same manner as in FIG. 12. In this case, the customer can specify the product to be labeled by operating the product button BT1 arranged on the sheet of the tab TB-2 displayed at that time. Alternatively, the customer can specify (select) the product to be labeled by operating the product button BT1 after switching the sheet by operating the tabs TB-2 and TB-3 corresponding to prepackaged items of fruits and vegetables.

[0172] On the other hand, when the customer arrives at the weighing and pricing device 10 while having performed pre-item input, a pricing operation screen on which product buttons BT1 for each product pre-entered on the sheet of tab TB-1 are arranged is displayed in the same manner as in FIG. 13. In this case, the customer operates the product button BT1 arranged on the sheet of tab TB-1 displayed at that time to specify (select) the product to be priced. Also in this modified example, the mode in which the product buttons BT1 of the products pre-entered on the sheet of tab TB-1 are arranged emphasizes (gives priority to) and displays the pre-entered products from among the products registered in advance in the product master according to the classification as retail products. Note that, as described above, the mode of emphasizing (giving priority to) and displaying the pre-entered products is not limited to the example of switching the sheet (selected tab TB) as described above.

[0173] In response to one product being specified (selected) as the pricing target by the customer's operation on the product button BT1, the display on the customer display unit 106 in the weighing and pricing device 10 transitions from the pricing operation screen to the weighing guidance screen. Although not shown, on the weighing guidance screen, the product specified as the pricing target is indicated, for example, by the product name or a pattern representing the product, and a message is displayed to guide the customer to place the product specified as the pricing target on the weighing platform 109b. The weighing guidance screen in this case may be in the same manner as, for example, FIG. 14.

[0174] In a state where the weighing guidance screen is displayed, the customer places the product to be priced on the weighing platform 109b. In response to the product being placed on the weighing platform 109b, the weighing and pricing device 10 executes the pricing process. That is, the weighing and pricing device 10 determines the weight of the product when it determines that the weight of the product measured by the weighing unit 109 has stabilized, and calculates the price based on the determined weight and the unit price per weight.

[0175] In response to the execution of the valuation process in this way, the display on the customer display unit 106 transitions from the weighing guidance screen to the weighing result screen. FIG. 19 shows an example of the weighing result screen. In the figure, the same parts as those in FIGS. 12 to 15 and the like are denoted by the same reference numerals, and the description thereof will be omitted as appropriate. On the weighing result screen of this figure, in the weighing result area AR31, the weight of the product weighed in the weight area AR31-1 (in this case, the number calculated according to the weight and the unit weight) is shown, and in the total amount area AR31-3, it has changed to a state where the total amount corresponding to the calculated price of the product is shown.

[0176] Also, on the weighing result screen, the product name and pattern of the valued product are shown in the product confirmation area AR35.

[0177] Also, in the weighing guidance area AR36, the label issuance button BT16 and the connection information code area AR34 are arranged. The label issuance button BT16 is a button for performing an operation instructing the issuance of a label (single-item label) in which the valuation process result of the product to be valued is reflected. The connection information code area AR34 is an area where the connection information code CD is displayed. In the connection information code area AR34, a message is displayed to guide the customer using the mobile terminal device 40 to read the connection information code CD into the mobile terminal device 40.

[0178] Also, in the message area ARm, a message is displayed to guide the customer to perform either the operation of the label issuance button BT16 or the reading of the connection information code CD, for example, "PRINT LABEL OR READ CHORD".

[0179] In this case, the customer using the mobile terminal device 40 causes the mobile terminal device 40 to read the connection information code CD. Thereby, the mobile terminal device 40 is connected to the weighing and valuation device 10. The connection information code CD is erased when the mobile terminal device 40 is connected to the metering device 10. The metering device 10 transmits the product pricing information in which the current pricing process result is reflected to the connected mobile terminal device 40. Further, the metering device 10 issues a single-item label on which no code information is printed in response to the completion of the transmission of the product pricing information.

[0180] Also, a customer who does not use the mobile terminal device 40 operates the label issuance button BT16. In response to the operation of the label issuance button BT16, the metering device 10 issues a single-item label on which the code information in which the current pricing process result is reflected is printed.

[0181] In this modified example, at the stage where the pricing is finalized, the label issuance button BT16 and the connection information code area AR34 are displayed on the same screen as the metering result screen. In this case, the customer can determine whether to have the connection information code CD read or to operate the label issuance button BT16 according to whether the customer uses the metering device 10 or not. Also, in the case of this modified example, regardless of whether the mobile terminal device 40 is used or not, the procedures until the price is finalized by the pricing are common, so the customer can easily get used to the procedures.

[0182] After the label is issued, it may be configured to transition from the metering result screen to the display of the label pasting guidance screen. On the label pasting guidance screen, a message, a pattern, etc. for guiding the customer to paste the label issued from the metering device 10 onto the bag containing the product for which the current pricing was performed are displayed. On the label pasting guidance screen, the connection information code area AR34 displayed on the metering result screen is not arranged. That is, the display of the label pasting guidance screen is performed after the display of the connection information code is completed. The customer is guided to lift the product from the weighing platform 109b and paste the label taken out from the label discharge port 110a onto the bag containing the product. The label attachment guidance screen is erased, for example, in response to the sensor provided at the label discharge port 110a detecting that the label has been taken out. Instead of erasing the label attachment guidance screen, the customer display unit 106 transitions to the display of a valuation operation screen for specifying the item to be valued next. In this case, when the current valuation process is performed in response to an operation on a valuation operation screen with the preset keys arranged as in FIG. 12, the next transition may be made to a valuation operation screen similar to FIG. 12. On the other hand, when the current valuation process is performed in response to an operation on a valuation operation screen corresponding to the pre-item input as in FIG. 13 and there are still items among the pre-item input products that have not been valued, the next transition may be made to a valuation operation screen similar to FIG. 13. Note that at the timing when the label is taken out from the label discharge port 110a, for example, if there is still some heavy object on the weighing platform 109b, a screen is displayed to guide the customer to remove the heavy object on the weighing platform 109b.

[0183] [Fifth Modification Example] Regarding the predetermined processes that the portable terminal device 40 was made to execute in the above embodiments, a higher-level device such as the transaction management server 50 may be configured to share or execute in cooperation with the portable terminal device 40. Also, regarding the predetermined processes that the weighing and valuation device 10 executes, a higher-level device such as the transaction management server 50 may be configured to share or execute in cooperation with the portable terminal device 40. Furthermore, regarding the predetermined processes that the transaction management server 50 executes, the portable terminal device 40 or the weighing and valuation devices 10, 10A may be configured to share or cooperate with the portable terminal device 40 or the weighing and valuation devices 10, 10A.

[0184] [Summary of Embodiments] [Technical Field] The present invention relates to a weighing and valuation device and a sales system. [Background Art] In a store, a sales system is introduced that allows customers to operate their own portable terminal devices to register products by themselves (see, for example, Patent Document 1). [Prior Art Documents] [Patent Documents] [Patent Document 1] Japanese Patent No. 5056161 [Summary of the Invention] [Problems to be Solved by the Invention] When selling weighed products, a weighing device is used. In the above sales system, a sales floor using a weighing device may be provided. The present invention has been made in view of such circumstances, and in a sales system in which product registration is performed by a portable terminal device held by a customer, an object is to enable smooth product registration using a weighing device.

[0185] [Means for Solving the Problems] (1) As described above, one aspect of the present embodiment is a weighing device in a sales system including a weighing device (10) and a portable terminal device (49) used by a customer for product registration, the weighing device including a weighing result column (for example, weighing result area AR31) and display means for displaying connection information (for example, connection information code CD) for communicably connecting to the portable terminal device on the same screen (for example, pricing operation screen), and connection means for communicably connecting to the portable terminal device that has read the connection information.

[0186] According to the above configuration, the weighing and pricing device 10 can display, on the pricing operation screen, for example, a weighing result area AR31 showing the weighing result of weighed goods and a mobile terminal device 40 used by a customer for product registration. As a result, while the pricing operation screen is being displayed, the customer can input the item of the goods to be priced by connecting the mobile terminal device 40 and the weighing and pricing device 10 while checking the result (weight, price, etc.) of weighing the weighed goods targeted for pricing. Thereby, in a sales system in which product registration is performed by the mobile terminal device held by the customer, product registration using the weighing and pricing device can be smoothly performed.

[0187] (2) One aspect of the present embodiment is the sales system described in (1), wherein the display means displays product buttons (BT1) corresponding to products classified as weighed goods.

[0188] According to the above configuration, preset keys prepared in advance corresponding to weighed goods can be arranged on the pricing operation screen.

[0189] (3) One aspect of the present embodiment is the sales system described in (1) or (2), further comprising reception means for receiving information on goods to be weighed by the weighing and pricing device from outside the weighing device (for example, a tag device, a motion sensor), and selection display means (for example, displaying product buttons BT1) for selectively displaying pre-registered products. When the reception means receives the information on the goods, the selection display means selectively displays the information on the goods received by the reception means in an emphasized manner (for example, displaying product buttons BT1 on the sheet of tab TB-1).

[0190] According to the above configuration, for example, on the value-assignment operation screen in the initial state, when there is no pre-item input, it is possible to display in a manner where product buttons BT1 (preset keys) corresponding to all weighed products are arranged on the sheet of tab TB-2. Moreover, in response to the pre-item input being performed, for the value-assignment operation screen in the initial state, it is possible to switch the display to a mode where, among the preset keys, the product button BT1 of the product with the pre-item input is arranged on the sheet of tab TB-1. As a result, it becomes easier to perform the operation of specifying the product to be value-assigned when the pre-item input is performed.

[0191] (4) One aspect of this embodiment is the sales system according to any one of (1) to (3), wherein the display means erases the connection information at a predetermined timing after being communicably connected to the mobile terminal device by the connection means.

[0192] According to the above configuration, when the weighing value-assignment device 10 and the mobile terminal device 40 are communicably connected, the display of the connection information code CD stops. As a result, it becomes easier to grasp that the weighing value-assignment device 10 and the mobile terminal device 40 are communicably connected, and it is possible to prevent, for example, other customers from inadvertently attempting to connect.

[0193] (5) One aspect of this embodiment is the sales system according to any one of (1) to (6), wherein the display means further displays a search area for searching for the product to be the target of the value-assignment process on the same screen.

[0194] According to the above configuration, it becomes possible to search for products by operating the value-assignment operation screen, and the usability of the value-assignment operation screen is improved.

[0195] (6) One aspect of this embodiment is the sales system according to any one of (1) to (5), wherein the display means displays the product button and the connection information on the same screen under a standby state where no operation related to value-assignment is being performed.

[0196] According to the above configuration, from the stage of waiting for an operation related to customer valuation, the product button BT1 and the connection information code CD can already be displayed on the valuation operation screen. As a result, a customer who arrives at the weighing and valuation device 10 can immediately start an operation related to valuation.

[0197] (7) One aspect of the present embodiment is the sales system according to any one of (1) to (6), comprising printing instruction means (for example, label issuance button BT16) for instructing printing of the valuation information made by the weighing and valuation device, and the display means displays the printing instruction means and the connection information on the same screen.

[0198] According to the above configuration, a customer using the mobile terminal device 40 can have the weighing and valuation device 10 issue a label (one without a barcode printed) after confirming the registration of the product by having the connection information code arranged on the weighing result screen read. On the other hand, a customer who does not use the mobile terminal device 40 can operate the label issuance button BT42 arranged on the same weighing result screen to issue a label (one with a barcode printed). That is, the weighing result screen is enabled for both customers who use the mobile terminal device 40 and those who do not to perform operations for label issuance. At the same time, the weighing and valuation device 10 can distinguish and issue a label for a customer using the mobile terminal device 40 (a label without a barcode printed) and a label for a customer not using the mobile terminal device 40 (a label with a barcode printed) according to whether the label issuance operation is by reading the connection information code or by operating the label issuance button BT16.

[0199] (8) One aspect of the present embodiment is the sales system according to any one of (1) to (7), comprising user information display means for displaying information about the user of the mobile terminal device connected by the connection means (for example, connection-compatible information (terminal number, membership number, membership registration name, handle name, character, sorting number, background color setting of the valuation operation screen, connection elapsed time, etc.)).

[0200] According to the above configuration, in response to being connected to the mobile terminal device 40, the metering device 10 can display information about the user of the connected mobile terminal device 40 (for example, a customer using the mobile terminal device 40). Thereby, the customer can easily confirm that his / her mobile terminal device 40 is connected to the metering device 10. In addition, other customers can also easily understand that the metering device 10 is being used by a customer other than themselves, so it is possible to prevent other customers from inadvertently connecting their own mobile terminal devices 40 to the metering device 10.

[0201] (9) One aspect of the present embodiment is a sales system including a metering device and a mobile terminal device used by a customer for product registration, the sales system including display means for displaying a metering result column and connection information for communicably connecting to the mobile terminal device on the same screen on the metering device, and connection means for communicably connecting the mobile terminal device that has read the connection information to the metering device.

[0202] In addition, a program for realizing functions as the above-described metering device 10, mobile terminal device 40, transaction management server 50, etc. may be recorded on a computer-readable recording medium, and the program recorded on this recording medium may be read into a computer system and executed to perform processing as the above-described metering device 10, mobile terminal device 40, transaction management server 50, metering sales management server 60, etc. Here, "reading and executing the program recorded on the recording medium into the computer system" includes installing the program in the computer system. The "computer system" as used herein shall include hardware such as an OS and peripheral devices. Further, the "computer system" may include a plurality of computer devices connected via a network including a communication line such as the Internet, WAN, LAN, dedicated line, etc. Also, the "computer-readable recording medium" refers to a portable medium such as a flexible disk, magneto-optical disk, ROM, CD-ROM, etc., and a storage device such as a hard disk built into the computer system. Thus, the recording medium storing the program may be a non-transitory recording medium such as a CD-ROM. Also, the recording medium includes an internal or external recording medium provided and accessible from a distribution server for distributing the program. The code of the program stored in the recording medium of the distribution server may be different from the code of the program in a form executable by the terminal device. That is, as long as it can be downloaded from the distribution server and installed in a form executable by the terminal device, the form stored in the distribution server does not matter. Note that the program may be divided into a plurality of parts, downloaded at different timings, and then combined on the terminal device, or the distribution servers for distributing the respective divided programs may be different. Furthermore, the "computer-readable recording medium" shall also include a volatile memory (RAM) inside a computer system that becomes a server or a client when a program is transmitted via a network and holds the program for a certain period of time. Also, the above program may be for realizing a part of the above-described functions.Furthermore, it may be a so-called difference file (difference program) that can be realized in combination with a program already recorded in the computer system to achieve the above-described functions.
