Description

The present invention relates to a product registration system, a registration terminal, a weighing device, a product registration method, a weighing method, and a program.

In recent years, a so-called self-checkout system, in which a customer registers a product and makes a payment, has become widespread. For example, there is known a self-checkout system for registering and paying for products using a registered terminal such as a mobile terminal owned by a customer (see, for example, Patent Document 1).

Here, the products in the self-registration system include the products to be weighed that need to be weighed. When registering a product to be weighed, for example, the weighing device and the registration terminal are connected by communication. The number of registered terminals to which the weighing device can communicate and connect at one time is limited. The registration terminal reads the product code that identifies the product to be weighed, and transmits the reading result to the weigh-in terminal connected by communication. The weighing device weighs the product to be weighed by the customer and transmits the weighing result including the selling price to the registration terminal. As a result, the registration of the product to be weighed is completed on the registration terminal. Information on various products registered on the registration terminal is also managed on the cloud server.

Japanese Unexamined Patent Publication No. 2016-21903

However, in the prior art, since the number of registered terminals to which the weighing device can communicate and connect at one time is limited, if the connection time between one registered terminal and the weighing device is long, the registered terminals of other customers are correspondingly long. It also takes a long time for the measuring device to be unable to communicate with each other. For this reason, there is a problem that it may not be possible to efficiently register the products to be weighed.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a technique capable of improving the efficiency of registration of a product to be weighed.

In order to solve the above-mentioned problems, the product registration system according to one aspect of the present invention is a product registration system including a weighing device for weighing a weighing target product requiring weighing and a registration terminal for registering the weighing target product. Therefore, the registration terminal includes a registration means for temporarily registering a product to be weighed and a registration terminal communication means for transmitting product identification information for identifying the temporarily registered product temporarily registered by the registration means to the weighing device. The measuring device is provided with the product identification information on the condition that the measuring device communication means for receiving the product identification information from the registered terminal communication means and the product identification information are received by the measuring device communication means.

(Embodiment)
(Network configuration of shopping system 1)
FIG. 1 is an explanatory diagram showing a network configuration of the shopping system 1 according to the embodiment. The shopping system 1 is an example of a product registration system. In addition, in this specification, "customer", "customer", and "user" are synonymous unless otherwise specified.

In FIG. 1, the shopping system 1 includes a management device (store computer, store controller) 10, a cloud server 20, a weighing device 30, a POS (Point Of Sales) terminal 40, and a mobile terminal 50. The mobile terminal 50 is an example of a registered terminal. The management device 10, the cloud server 20, the weighing device 30, the POS terminal 40, and the mobile terminal 50 are connected to each other via a network so as to be able to communicate with each other.

The management device 10 is a computer device that manages the weighing device 30 and the POS terminal 40. The management device 10 stores, for example, a product master or the like. The product master is a file that stores product information such as product identification information (for example, JAN code), product name, and selling price of each product. In addition, the management device stores the product identification information, the product name, and the unit price of the product to be weighed for each product to be weighed.

The cloud server 20 is a computer device (for example, a server device) including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a communication unit, and the like. The cloud server 20 manages various types of information such as information about customers, information about stores, and information about products for each store. The information managed (generated and stored) by the cloud server 20 will be described later with reference to FIG.

The weighing device 30 is a computer device that weighs the product to be weighed. The weighing device 30 calculates the amount of the product to be weighed by using the weighed weight (or the number) and the unit price of the product to be weighed. The product to be weighed is a product different from a normal product. Here, for example, a JAN (Japanese Article Number) code is attached to a normal product. When the mobile terminal 50 reads the JAN code, it inquires of the cloud server 20 for the read JAN code and obtains the price data associated with the JAN code.

On the other hand, the products to be weighed are products whose prices differ depending on the weight and quantity of the products. The products to be weighed are, for example, fresh foods such as vegetables, fruits, fresh fish, and meat. The weighing device 30 prints and outputs a label in which the amount and weight of the product to be weighed are bar-coded. The label contains the price. That is, the NON-PLU (Price Look Up) method is used for the label (bar code) attached to the product to be weighed. Although a plurality of weighing devices 30 are illustrated in FIG. 1, the number of measuring devices 30 may be one.

The POS terminal 40 is a computer device capable of executing a settlement process (also referred to as an accounting process or a settlement process) for performing a settlement (settlement) of a product read by the mobile terminal 50. The POS terminal 40 may at least be capable of executing the settlement process. In the present embodiment, the POS terminal 40 can execute a registration process for registering a product to be purchased in addition to the settlement process. The POS terminal 40, for example, is set to the accounting-only mode described later, so that the product read by the mobile terminal 50 is settled. Although a plurality of POS terminals 40 are illustrated in FIG. 1, the number of POS terminals 40 may be one.

The mobile terminal 50 is a portable computer device such as a smartphone, a tablet device, or a mobile phone, and is operated by a customer (a shopper who is a member of the store, etc.). In the present embodiment, the mobile terminal 50 is detachably attached to the shopping cart. However, the mobile terminal 50 may be installed so as not to be attached to and detached from the shopping cart. The mobile terminal 50 includes a communication unit, an imaging unit (camera), a touch panel, and the like. In addition, a shopping application (hereinafter, may be referred to as "this application") for registering and paying for products related to the shopping system 1 is installed in the mobile terminal 50. The mobile terminal 50 reads the barcode attached to the product by activating this application.

Specifically, the mobile terminal 50 accepts the registration of the product by scanning the barcode attached to the product and reading the product code. That is, the mobile terminal 50 has a recognition function for recognizing a barcode attached to a product. The recognition function provided in the mobile terminal 50 may be any as long as it can read the product code attached to the product, and the product may not be identified from the read product code. That is, the mobile terminal 50 only needs to be able to read the product code from the barcode as an object in the captured image (the image acquired as the through image) captured by the imaging function. ..

In addition, the mobile terminal 50 captures a product (for example, a peripheral portion with a barcode) and generates an captured image (image data). For example, the mobile terminal 50 generates an captured image by releasing the shutter at its own discretion. However, the mobile terminal 50 may generate the captured image by accepting the operation of the customer who is the operator and releasing the shutter.

Further, the mobile terminal 50 may be provided with an image recognition technology. Specifically, the mobile terminal 50 may be provided with an image recognition technique for extracting feature points from an image (through image, captured image) and recognizing an imaging target (object or the like). For example, the mobile terminal 50 may specify (estimate) the imaged product by using the image recognition technology. By using such an image recognition technique, the mobile terminal 50 can also identify fresh foods such as vegetables and fruits without a barcode, for example.

Further, the mobile terminal 50 transmits the read information to the cloud server 20. As a result, the product corresponding to the barcode is registered in the cloud server 20. In addition, the mobile terminal 50 displays a code (for example, a two-dimensional code: QR code (registered trademark)) corresponding to the registered product when making a payment. When the two-dimensional code is read by the POS terminal 40, the POS terminal 40 can perform the settlement. The POS terminal 40 is not limited to being able to settle by reading the QR code. For example, the POS terminal 40 may acquire information corresponding to the product purchased by the customer directly from the cloud server 20 or via the mobile terminal 50. Further, the device for performing settlement is not limited to the POS terminal 40. For example, it may be a computer device for payment that is installed so as not to be attached to and detached from the shopping cart. Note that this computer device may, for example, enable only payment of a card using a credit card or a prepaid card.

Further, in the present embodiment, the mobile terminal 50 is the property of the customer, but may be a loaned item lent to the customer by the store. The number of mobile terminals 50 (the number in operation) changes according to the number of visitors. In FIG. 1, two mobile terminals 50 are illustrated, but in reality, the number may be tens, hundreds, or more.

Specifically, in the full self mode, product registration using the clerk side scanner unit 412, the clerk side display unit 410, and the key operation unit 411 may be enabled. As a result, in the full self mode, the registration process can be performed on the clerk side and the customer side. In the full self mode, the registration of the product on the clerk side may be enabled or disabled by the operation of the clerk.

Further, in the full self mode, it is possible to accept the input of money even when the product registration process is being performed. In the full self mode, the settlement process is performed by inserting money into the change machine 409 and reading the card by the card settlement unit 408. The settlement process is performed after the registration process on the customer side or the clerk side is executed.

(About switching each operation mode)
Next, switching of the operation mode of the POS terminal 40 will be described. The operation mode is switched, for example, in response to an explicit mode switching operation for switching the operation mode by the clerk or a clerk code reading operation. Further, the operation mode may be switched, for example, according to a time condition.

The temporal condition is, for example, that a predetermined time has elapsed since the last operation, or that the switching time is set according to a preset schedule. In addition, the operation mode may be switched in response to a mode switching instruction from another device (another POS terminal 40, a management device 10, a specific mobile terminal owned by a clerk, etc.). The operation mode is switched by a clerk.

In addition to the above-mentioned operation modes, the plurality of operation modes include an aggregation mode, a maintenance mode, a training mode, and the like. The aggregation mode is a mode in which sales, sales, etc. are aggregated and inquired. The maintenance mode is a mode when a store clerk, a maintenance clerk, or the like performs setting work or maintenance work. The training mode is a mode in which a new clerk trains on the handling of the POS terminal 40.

Next, the functions of the weighing device 30 and the mobile terminal 50 according to the present embodiment will be described. The mobile terminal 50 (CPU 501) provisionally registers the product to be weighed. For provisional registration, it suffices if the product to be weighed can be identified by using the Non-PLU code or a number specially provided for the product to be weighed. For example, the provisional registration is a state in which the product identification information, the product name, the unit price, and the like are registered, and the weight and the selling price of the product are not registered. Further, even if the provisionally registered product is canceled, for example, the temporarily registered product is not treated as a reserved product described later. The temporarily registered product is stored in the memory 504.

When the bar code (product identification information) for identifying the weighing target product is read by the camera 507, the mobile terminal 50 temporarily registers the weighing target product obtained from the reading result of the barcode. The provisionally registered merchandise to be weighed is displayed on the display 509. The barcode that identifies the product to be weighed is displayed in the vicinity of the product to be weighed, for example. The display mode of the barcode may be a display on a display or a paper surface.

The communication unit 505 communicates with the communication unit 305 of the weighing device 30. Specifically, the communication unit 505 performs one-to-one short-range wireless communication with the communication unit 305 of the weighing device 30, for example, using Bluetooth. For one-to-one communication, it is necessary to set the function for performing one-to-one communication (hereinafter referred to as "short-range wireless communication function") to ON in the mobile terminal 50. Further, the mobile terminal 50 makes a one-to-one communication connection request to the weighing device 30. The weighing device 30 starts communication with the mobile terminal 50 in response to this connection request, and can receive the product identification information from the mobile terminal 50.

Here, the procedure for connecting the mobile terminal 50 and the weighing device 30 will be described. For example, the weighing device 30 is in a pairable state (standby state) for making a one-to-one communication connection when the mobile terminal 50 is not connected to the communication. When the short-range wireless communication is turned on, the mobile terminal 50 searches for surrounding devices capable of one-to-one communication and designates the weighing device 30. Then, when the same passkey is input to both the mobile terminal 50 and the weighing device 30, one-to-one communication becomes possible.

Information for causing the mobile terminal 50 to connect to the weighing device 30 (information for searching for surrounding devices, designating the weighing device 30, inputting a passkey, etc.) is a two-dimensional code (hereinafter referred to as a two-dimensional code). It is represented by a "connection code"). The connection cord is displayed, for example, on the touch panel 306 of the weighing device 30 in the standby state. Therefore, when the customer reads the connection code with the camera 507 of the mobile terminal 50, the search for surrounding devices, the designation of the weighing device 30, the input of the passkey, and the like are automatically performed. That is, when the customer reads the connection code with the camera 507 of the mobile terminal 50, the mobile terminal 50 automatically makes a connection request to the weighing device 30, and automatically makes a communication connection with the weighing device 30.

The connection cord is not limited to being displayed on the weighing device 30, and may be displayed and posted on paper or the like. Further, the one-to-one communication connection is not limited to being performed by reading the connection code, but is also performed by receiving from the customer each of the search for surrounding equipment, the designation of the weighing device 30, the input of the passkey, and the like. You may. Further, the connection request is not limited to being made from the mobile terminal 50 to the weighing device 30, and may be made from the weighing device 30 to the mobile terminal 50.

When the one-to-one communication connection is completed, the communication unit 505 transmits the product identification information for identifying the temporarily registered product to be measured to the weighing device 30 under the control of the CPU 501.

The communication unit 305 of the weighing device 30 communicates with the communication unit 505 of the mobile terminal 50 on a one-to-one basis. The communication unit 305 of the weighing device 30 receives the product identification information transmitted from the communication unit 505 of the mobile terminal 50. The CPU 301 of the weighing device 30 weighs the product to be weighed, which is identified by the product identification information received by the communication unit 305. The communication unit 305 transmits the measurement result to the mobile terminal 50 by short-range wireless communication. The weighing result includes the weight (or quantity) of the product placed on the platform 310, the selling price calculated using the weight (or quantity) and the unit price, and the product identification information (product code) of the product. And so on. That is, the weighing result corresponds to the product information of the product to be weighed.

The CPU 501 of the mobile terminal 50 actually registers the provisionally registered merchandise to be weighed based on the weighing result of the weighing device 30. The main registration is that all the information for performing the settlement is registered. Specifically, in the main registration, for example, in addition to the provisionally registered product identification information, product name, and unit price, the weight, selling price, and the like are registered. Further, the mainly registered product is different from the provisionally registered product in that, for example, when the main registration is canceled, it is treated as a reserved product described later.

Here, if the connection time between one mobile terminal 50 and the weighing device 30 is long, the time during which the communication connection between the other customer's form terminal 50 and the weighing device 30 cannot be made becomes long accordingly. For example, after one mobile terminal 50 and the weighing device 30 are connected by communication, a series of weighing operations such as the customer temporarily registering the weighing target product and placing the weighing target product on the weighing device 30 can be performed. If this is done, the one mobile terminal 50 will occupy the weighing device 30 for a long time. As a result, other customers cannot use the weighing device 30, and the efficiency of registering the weighing target product is reduced.

Therefore, in the present embodiment, the weighing device 30 receives the provisionally registered product identification information of the measurement target product from the mobile terminal 50, and the provisionally registered product (temporarily registered) indicated by the product identification information. Allows weighing of goods). In other words, the weighing device 30 enables the weighing of the goods to be weighed to some extent, provided that the goods to be weighed are provisionally registered in the mobile terminal 50. For example, in the present embodiment, the communication unit 305 of the weighing device 30 and the communication unit 505 of the mobile terminal 50 can perform one-to-one communication on the condition that the product to be weighed is provisionally registered in the mobile terminal 50. It has become. In other words, when the product to be weighed is not provisionally registered in the mobile terminal 50, the one-to-one communication connection between the weighing device 30 and the mobile terminal 50 is prohibited.

The subject (for example, "prohibition means") that controls to prohibit one-to-one communication connection is, for example, a mobile terminal 50. Specifically, even if the mobile terminal 50 reads the connection code, if the product to be weighed is not provisionally registered, the mobile terminal 50 may not make a connection request.

The main body that prohibits one-to-one communication connection may be the weighing device 30. In this case, the mobile terminal 50 may transmit the information regarding the provisionally registered product to be weighed immediately after the one-to-one communication connection. The information regarding the provisionally registered merchandise to be weighed may be information indicating the provisionally registered merchandise to be weighed or information indicating whether or not the merchandise to be weighed is provisionally registered. The weighing device 30 determines whether or not the tentatively registered product is tentatively registered by using the information about the tentatively registered merchandise to be weighed. Communication may be canceled (prohibited) on a one-to-one basis.

(Regarding notification to encourage temporary registration)
In the present embodiment, the weighing device 30 cannot be used unless the mobile terminal 50 is provisionally registered for the product to be weighed. For this reason, if the mobile terminal 50 has not been provisionally registered for the product to be weighed, it is notified to that effect. This will be specifically described. When the measurement target product is not temporarily registered, the mobile terminal 50 notifies that the temporary registration of the measurement target product is urged in response to the connection code being read by the camera 507. Specifically, when the one-to-one communication connection between the weighing device 30 and the mobile terminal 50 is prohibited, the mobile terminal 50 notifies that the provisional registration of the product to be weighed is urged. The mode of notification to encourage temporary registration is a display output from the display 509 and an audio output from the speaker.

(Notification of non-weighable products)
Further, the CPU 301 of the weighing device 30 weighs a measurable merchandise to be weighed (hereinafter referred to as “measurable product”) predetermined for each weighing device 30. The measurable products are, for example, various products corresponding to vegetables in the case of the weighing device 30 arranged in the vegetable section, and various products corresponding to fresh fish in the case of the measuring device 30 arranged in the fresh fish section. .. The product identification information that identifies the measurable product is stored in, for example, the memory 304. The product identification information that identifies the measurable product may be acquired from the management device 10.

When the provisionally registered merchandise to be weighed is not a measurable product (if it is an unmeasurable product), the mobile terminal 50 notifies that the merchandise cannot be weighed. For example, the weighing device 30 is a determining entity that determines whether or not the tentatively registered merchandise to be weighed is a measurable product. In this case, the weighing device 30 determines whether or not the product identification information received from the mobile terminal 50 is included in the product identification information indicating the measurable product stored in the memory 304. If a negative determination result is obtained in the determination, the weighing device 30 transmits information indicating that fact to the mobile terminal 50. When the mobile terminal 50 (CPU501) receives the information, it notifies that the measurement is impossible (notification of the non-weighable product). The mode of notifying the non-weighable product is a display output from the display 509 and a voice output from the speaker.

The mobile terminal 50 may be the determining entity for determining whether or not the tentatively registered merchandise to be weighed is a measurable product. In this case, for example, the connection cord may include product identification information that identifies the measurable product. When the mobile terminal 50 reads the connection code, it may determine whether or not the product identification information of the tentatively registered merchandise to be weighed is included in the merchandise identification information of the measurable product obtained from the connection code. .. When the mobile terminal 50 obtains a negative determination result in the determination, the mobile terminal 50 may notify that the measurement is impossible.

(About notification that prompts the one-to-one communication function to be turned on)
Further, the CPU 301 of the mobile terminal 50 sets either a state in which the one-to-one communication connection function (short-range wireless communication function) is on or a state in which it is off. When the short-range wireless communication function is set to the off state, the mobile terminal 50 is notified to prompt the change of the setting of the on state of the function in response to the connection code being read by the camera 507 (hereinafter, "" Function on notification ") is performed.

The function-on notification may be, for example, the timing of reading the barcode of the product to be weighed, or the timing of reading the connection code. Further, the mobile terminal 50 may determine on / off of the function when notifying that the temporary registration is urged. That is, the mobile terminal 50 may determine on / off of the function when the communication connection with the weighing device 30 is prohibited. Further, in this case, when the short-range wireless communication function is determined to be off in the determination, the mobile terminal 50 may perform a function-on notification as well as a notification to prompt temporary registration. The mode of the function-on notification is, for example, a display output from the display 509 or a voice output from the speaker.

(Example of information managed by cloud server 20)
FIG. 6 is an explanatory diagram showing an example of various information for each mobile terminal 50 managed by the cloud server 20. The cloud server 20 stores various information including (A) customer information, (B) store information, and (C) basket information.

(Customer information)
FIG. 6A shows an example of customer information. Customer information is information for managing individual customers. Specifically, the customer information includes customer identification information, a customer name, a customer registration date, a customer rank, and a number of points.

The customer identification information is identification information that uniquely identifies a customer. The customer identification information may be, for example, application identification information uniquely assigned to each installed shopping application when the shopping application of the present embodiment is installed. The application identification information may be, for example, a number uniquely (for example, sequentially) assigned to each installed shopping application. Alternatively, the application identification information may be terminal identification information unique to the mobile terminal 50 in which the shopping application is installed. The terminal identification information is hardware that is unique to the hardware of the mobile terminal 50, such as a telephone number assigned to a customer who is a user of the mobile terminal 50, a MAC (Media Access Control) address, and the like. It may be identification information.

The customer name is a customer's name, nickname, or the like.
The customer registration date is the date and time when the customer information is newly registered in the cloud server 20.
The customer rank is a rank according to the purchase record of the customer. 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 actual transaction (product registration) starts, other information (customer rank, etc.) Is not generated.

The number of points is the number of points given to the customer by shopping using this application. The number of points may include the number of points for each store. When the cloud server 20 generates the customer information of a new customer, the cloud server 20 generates the customer identification information, the customer name, and the customer registration date.

The cloud server 20 uses, for example, a shopping application for using the shopping service by the cloud server 20 from the outside (for example, a predetermined server that provides the entire application, the cloud server 20) at the time of customer registration (for example, the mobile terminal 50 provides a general application). Generate and store customer identification information (when downloading or installing). Further, for example, when registering a customer, the cloud server 20 acquires the information entered in the name field of the registration form (input form) using the mobile terminal 50 and stores it as the customer name. Further, the cloud server 20 acquires, for example, the current date and time at the time of customer registration and stores it as the customer registration date.

(store information)
FIG. 6B shows an example of store information. Store information is information for managing each store. Specifically, the store information includes the store identification information, the store name, the store identification information 1 (two-dimensional code information), and the store identification information 2 (location information).
The store identification information includes a store (store name) or company code and a branch code.
The store name is the name of the store, and is composed of, for example, a store name (store name) or a company name and a branch name.

The store identification information 1 and 2 are information for identifying a store to be traded (a store where products are bought and sold). The store identification information 1 is, for example, two-dimensional code information. The store identification information 2 is location information (GPS information) indicating the location of the store. In the example shown in FIG. 6B, the store identification information and the store identification information 1 are stored separately, but since both are information that can uniquely identify the store, at least one of them is used. It suffices if the information is stored.

The cloud server 20 may acquire and store store information and the like from the outside (a server (not shown) of the headquarters that controls each store). Further, the cloud server 20 stores a part or all of the store information in another device (a file server or the like accessible to the cloud server 20) instead of or in addition to storing the store information in the storage unit in the own device. You may remember.

(Basket information)
FIG. 6C shows an example of basket information. Basket information is information about a customer's purchase at a store. Specifically, the basket information includes basket identification information, transaction start date and time, transaction end date and time, customer identification information, and registered product information.
The basket identification information is information for identifying the basket information. Specifically, the basket identification information includes the store identification information, the date, and the serial number (for example, the serial number for each date of each store).

The transaction start date and time is the date and time when the transaction is started, for example, the generation date and time of the basket information. The transaction start date and time may be the registration date and time of one product (the date and time when the registered product information (registered product 1) shown in FIG. 6C is stored). Further, the registration date and time for each product may be stored separately.

The transaction end date and time is the date and time when the transaction was completed, and specifically, the date and time when the transaction was settled. For example, the transaction end date and time may be the date and time when the settlement is started or the date and time when the settlement is completed.
The customer identification information is information that identifies the customer who conducts the transaction. The cloud server 20 generates basket identification information, transaction start date and time, and customer identification information when the basket information is generated, but since it is before the actual transaction (product registration) starts, other information (transaction end). Date and time, etc.) are not generated.

The registered product information (total) is information that is updated every time a product is registered. The registered product information (total) includes the number of products (number of products), the estimated subtotal amount, the subtotal amount, and the like. The registered product information (1) is the registration information of one product. The registered product information (2) is the registration information of two products. In the example shown in FIG. 6 (C), the registered product information (3) to the registered product information (N: N is an integer) are not shown. The registered product information (N) includes a product code, a product name (product name), a price, and the like.

The registered product information (N) may include the registration date and time of the product of the N item. That is, the cloud server 20 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 material for determining the necessity of applying a service such as a time service and the effect after application.

Next, the reserved product will be described. The reserved product is, for example, a product to be purchased, but the registration is suspended without being normally registered. Here, the registered product information is a product that is stored when the product code is successfully scanned and the product can be identified based on the product code. On the other hand, the reserved product information is a product that is stored when the product code is not successfully scanned, or when the product code is successfully scanned but the product cannot be identified based on the product code.

The pending products include a pending product with a read NG and a reserved product with an inquiry NG. The pending product of reading NG is a reserved product that could not be registered because the scanning of the product code failed (the scanning by the scanner became NG). For example, if there are wrinkles on the product package, or if the barcode is printed with blur or stains, the barcode may not be recognized due to a timeout.

Here, it will be described in detail that the barcode is not recognized due to the timeout. The mobile terminal 50 includes various sensors (for example, a gyro sensor, an acceleration sensor, a distance sensor, etc.), and can determine that a barcode is being read by using the detection results of the various sensors and the imaging results of the camera 507. is there.

Specifically, the mobile terminal 50 is in a situation where the mobile terminal 50 is tilted using the detection results of various sensors, and the product exists at a position separated from the mobile terminal 50 by a certain distance. It is possible to determine the situation as if the barcode is being read. Then, after determining that the barcode is being read, the mobile terminal 50 identifies the read NG pending product as a timeout when the barcode cannot be read within a predetermined time.

Further, the reading NG may be, for example, a case where the product is put into the basket by pretending to read the barcode of the product. Therefore, since there is a possibility of illicit operation, the reserved product (reading NG) can be said to be a reserved product for confirming illicit operation, which requires confirmation of tampering.

The pending product of inquiry NG succeeded in scanning the product code (not reading NG), and although the product master was inquired about the product with the product code, the product identification failed (product inquiry was NG). ) This is a pending product that could not be registered.

The pending product information (total) includes the number of products (number of products) of the reserved products (reading NG, inquiry NG) and the number of products for which unauthorized operation is confirmed.

The reserved product information (pending product N: N is an integer) is information on the reserved product of N items, and includes the reserved product type of the reserved product of N items. The hold product type is information indicating whether the hold product is a hold product of reading NG or a hold product of inquiry NG. In this example, "1" of the reserved product type indicates read NG, and "2" of the reserved product type is inquiry NG.

Further, the reserved product information of the reserved product (reading NG) includes the image data of the reserved product of the read NG (image data captured at the time of reading NG) in addition to the reserved product type "1 (reading NG)". For example, the reserved product information (3) includes the reserved product type "1 (reading NG)" and image data.

Further, the reserved product information of the reserved product of the inquiry NG includes the product code of the reserved product of the inquiry NG in addition to the reserved product type "2 (inquiry NG)". For example, the reserved product information (1) includes a product code in addition to the reserved product type "2 (inquiry NG)".

In addition, the cloud server 20 stores a part or all of the basket information in another device (a file server or the like accessible to the cloud server 20) instead of or in addition to storing the basket information in the storage unit in the own device. You may remember.

(Example of product registration and settlement processing in shopping system 1)
FIG. 7 is a sequence diagram showing a flow of product registration and settlement processing in the shopping system 1. Note that FIG. 7 describes a flow from a customer visiting a store, registering a product to be purchased using his / her mobile terminal 50, and completing the settlement of the product on the POS terminal 40. ..

Step S601: First, the mobile terminal 50 acquires information that identifies the store (store identification information). Here, an example of the acquisition mode of the store specific information will be described. For example, a two-dimensional code indicating store identification information is displayed near the entrance of the store. The two-dimensional code may be displayed and output on a predetermined display device, or may be displayed and output by printing on a medium.

The printed medium is, for example, a paper medium. This paper medium may be affixed near the entrance of the store or may be distributed to customers at the store. The camera 507 of the mobile terminal 50 scans the two-dimensional code by the operation of the customer who visits the store. As a result, the mobile terminal 50 can acquire the store specific information. The two-dimensional code may include store identification information for identifying the store.

Further, the mobile terminal 50 may display a screen prompting the scanning of the two-dimensional code as the initial screen when the application is activated in response to the operation of the customer who visits the store. In addition, the mobile terminal 50 starts the application by scanning the two-dimensional code, connects to the cloud server 20, and displays a screen notifying that the connection is being made to the cloud server 20 as an initial screen. You may.

In addition, as another example of the acquisition mode of store specific information, acquisition of location information can be mentioned. For example, the mobile terminal 50 acquires location information (GPS information) according to the operation of a customer who visits the store. This location information is information that replaces the store specific information. The mobile terminal 50 acquires location information and connects to the cloud server 20 by activating this application in response to an operation of a customer who visits the store, and notifies that the cloud server 20 is being connected as an initial screen. The screen to be displayed may be displayed.

In addition, in the identification of the store using the location information, a plurality of stores may be specified. That is, it may not be possible to identify one store. In this case, the cloud server 20 may transmit information indicating that fact or information prompting the identification of the store to the mobile terminal 50. Then, when the mobile terminal 50 receives these information from the cloud server 20, it displays a selection screen for the customer to identify the store, or notifies that the customer is prompted to scan the two-dimensional code indicating the store identification information. do it.

The mobile terminal 50 that has acquired the store identification information requests the cloud server 20 to start a transaction. Specifically, as shown in the transmission / reception data D1 of FIG. 7, the mobile terminal transmits the acquired store identification information and the customer identification information to the cloud server 20. The customer identification information is information stored in the cloud server 20 or the mobile terminal 50, for example, when a new customer is registered (for example, when the application is installed on the mobile terminal 50). Specifically, the information such as the name entered in the registration form is stored in the cloud server 20 and the mobile terminal 50 with the customer identification information attached by the cloud server 20.

Further, when the mobile terminal 50 acquires the store specific information, the mobile terminal 50 may output information on the service being implemented at the store (flyer information distributed on that day) and available coupon information on the display screen. For example, service-related information and coupon information may be received from the cloud server 20 by the mobile terminal 50 making a transaction start request to the cloud server 20.

The mobile terminal 50 also stores the destination information (address of the cloud server 20) when newly registering a customer. The two-dimensional code displayed near the entrance of the store may include the destination information in addition to the store identification information. The mobile terminal 50 can also access the cloud server 20 by acquiring the destination information as well as the store identification information by scanning the two-dimensional code.

Step S602: When the cloud server 20 receives the customer identification information and the store identification information as a transaction start request from the mobile terminal 50, the cloud server 20 generates basket information of the transaction. Specifically, as shown in FIG. 6C, the cloud server 20 generates basket identification information, transaction start date and time, and customer identification information. Since the cloud server 20 is before the start of the actual transaction (product registration), other information (transaction end date and time, etc.) is not generated at this timing.

Specifically, when the cloud server 20 receives the store identification information and the customer identification information as a transaction start request from the mobile terminal 50, the cloud server 20 refers to the store information (see FIG. 6B) and identifies the store identification information. To do. When the cloud server 20 receives the location information from the mobile terminal 50, the cloud server 20 refers to the store identification information 2 of the store information to specify the store identification information corresponding to the location information. When the store identification information is included in the two-dimensional code, the cloud server 20 can also acquire the store identification information by combining the received two-dimensional code.

Further, when the cloud server 20 receives the transaction start request (store identification information and customer identification information) from the mobile terminal 50, the cloud server 20 acquires the current date and issues (numbers) the serial number. Further, the cloud server 20 combines the acquired store identification information, the acquired current date, and the issued serial number, and stores the acquired store identification information as basket identification information.

Further, when the cloud server 20 receives the transaction start request from the mobile terminal 50, the cloud server 20 stores the current date and time in the transaction start date and time (generation date and time) in the basket information. Further, when the cloud server 20 receives the transaction start request from the mobile terminal 50, the cloud server 20 stores the customer identification information received from the mobile terminal 50 in the customer identification information in the basket information.

Step S603: When the cloud server 20 generates the basket of the transaction, it generates the product registration initial screen information (screen information of the product registration screen which is the initial screen) and transmits it to the mobile terminal 50. Specifically, the cloud server 20 transmits the basket identification information to the mobile terminal 50 together with the product registration initial screen information (transmission / reception data D2 in FIG. 7).

Step S604: When the mobile terminal 50 receives the basket identification information and the product registration initial screen information from the cloud server 20, the mobile terminal 50 stores the basket identification information and displays the product registration initial screen on the display unit.

Step S605: The mobile terminal 50 scans the bar code attached to the product and reads the product code in response to the operation of the customer. When the barcode scanning is successful, the mobile terminal 50 acquires the product code and transmits the acquired product code and the basket identification information to the cloud server 20 (see transmission / reception data D3 in FIG. 7). When the read product is, for example, an age confirmation product (specific product), basket identification information and information indicating the specific product are transmitted as transmission / reception data D3.

Here, although the customer scans the barcode, the product may not be registered (there may be unscanned products). Unscanned merchandise (pending merchandise) may be caused by fraudulent activity by the customer. An unscanned product occurs rather than fraudulently, for example, when an unfamiliar customer attempts to scan a barcode, but the barcode cannot be scanned successfully. In addition to this, there is a case where the product to be registered as a product is a product (so-called NON file product) that is not registered in the product master even though the barcode is scanned.

On the other hand, the case where the unscanned product is caused by fraudulent activity is the case where the customer puts the product into the shopping cart without scanning the barcode or pretending to scan the barcode. The detection of fraud includes, for example, a scan result indicating whether or not a barcode is scanned, a camera image image of the inside of a shopping cart, a detection result of detecting the total weight of products in the shopping cart, and the like. Is done by using. The unscanned product is transmitted to the cloud server 20 as a reserved product in the transmission / reception data D3. In this case, the basket identification information and the information indicating the reserved product are transmitted as the transmission / reception data D3.

Further, the product without the barcode may be a reserved product according to the operation of the customer. In this case, the customer may be urged to take an image of the reserved product, and the imaged result may be transmitted to the cloud server 20 or the POS terminal 40. As a result, the store clerk can easily identify the reserved product by displaying the imaged result (image) and the reserved product in association with each other at the time of payment.

Step S606: When the cloud server 20 receives the product code and the basket identification information from the mobile terminal 50, the cloud server 20 identifies the basket information including the received basket identification information.

Step S607: The cloud server 20 updates the registered product information included in the specified basket information. Specifically, when the cloud server 20 receives the product code of N items, the cloud server 20 stores the product code as the product code of the registered product information (registered product N). Further, the cloud server 20 stores the product code, the product name, and the price in association with each other as product information (registered product N). Further, the cloud server 20 updates the cumulative information (cumulative number of products, subtotal amount, etc.) of the registered product information in the specified basket information.

Step S608: When the cloud server 20 updates the registered product information in the basket, it generates product registration update screen information (screen information of the product registration screen which is an update screen to which the registered product is added) and sends it to the mobile terminal 50. Send. Specifically, the cloud server 20 transmits the basket identification information to the mobile terminal 50 together with the product registration update screen information (transmission / reception data D4 in FIG. 7).

Step S609: When the mobile terminal 50 receives the basket identification information and the product registration update screen information from the cloud server 20, the mobile terminal 50 displays the product registration update screen in which the product is added to the registration screen. Although not shown in FIG. 7 for convenience of explanation, the processes of steps S605 to S609 are repeatedly executed every time the barcode attached to the product is scanned. That is, the processing of steps S605 to S609 loops until the accounting instruction of step S610 described later is received.

Step S610: The mobile terminal 50 receives an accounting instruction operated by the customer. For example, the mobile terminal 50 receives an accounting instruction by pressing the accounting button displayed on the display 509.

Step S611: When the mobile terminal 50 receives the accounting instruction, the mobile terminal 50 generates a two-dimensional code. This two-dimensional code includes information (for example, basket identification information) necessary for executing the settlement process on the POS terminal 40 for the product to be purchased. When the mobile terminal 50 generates the two-dimensional code, the generated two-dimensional code is displayed on the display 509.

Step S612: The customer who has completed the registration of the product goes to the POS terminal 40 and causes the customer side scanner unit 406 of the POS terminal 40 to scan the two-dimensional code displayed on the display 509 of the mobile terminal 50. As a result, the POS terminal 40 can acquire the basket identification information.

Step S613: When the POS terminal 40 reads the two-dimensional code displayed on the display 509 of the mobile terminal 50, the POS terminal 40 requests the cloud server 20 to calculate the subtotal amount. For example, the POS terminal 40 transmits a calculation request (small calculation output request information) requesting the calculation of the subtotal amount and the basket identification information restored from the two-dimensional code to the cloud server 20 (transmission / reception data D5 in FIG. 7). ..

Step S614: When the cloud server 20 receives the basket identification information and the small calculation output request information from the POS terminal 40, the cloud server 20 identifies the basket information including the received basket identification information.

Step S615: When the cloud server 20 specifies the basket information, the cloud server 20 calculates the subtotal amount (registered product information (total)) included in the basket information. If there is a discount for each product, the discount amount may be calculated for each product in step S615 to calculate the subtotal amount. If the tax rate is different for each product, the subtotal amount may be calculated in consideration of the tax rate for each product in step S615.

Step S616: The cloud server 20 transmits the subtotal information indicating the calculated subtotal amount to the POS terminal 40 together with the basket identification information (transmission / reception data D6 in FIG. 7). If the specified basket information includes a specific product such as an age confirmation product or a reserved product, the transmission / reception data D6 including the information of the specific product is transmitted to the POS terminal 40.

Step S617: When the POS terminal 40 receives the subtotal information from the cloud server 20, the POS terminal 40 displays the subtotal amount on the customer side display unit 405. If there are reserved products, the subtotal amount excluding the reserved products may be displayed, or the subtotal amount may not be displayed. In addition, if there is a specific product such as an age confirmation product, notification processing is performed. In the notification process, the POS terminal 40 transmits, for example, information indicating that there is a reserved product or a specific product to a monitoring device or a terminal device owned by a clerk, or information for sending the clerk to the POS terminal 40. Further, in the notification process, the POS terminal 40 displays a notification screen indicating that there is a reserved product or a specific product on the customer side display unit 405 or the clerk side display unit 410.

Step S618: The POS terminal 40 executes payment (settlement processing). In the settlement process, the POS terminal 40 accepts the selection of the payment type. The payment type may be registered in advance in this application. When the payment type is registered, the POS terminal 40 does not have to display the payment type selection screen. Even when the payment type is registered, the POS terminal 40 may display a screen for selecting the payment type.

Further, in the settlement process, the POS terminal 40 issues a receipt and transmits the settlement completion information together with the basket information to the cloud server 20. Then, the cloud server 20 stores the transaction end date and time (settlement date and time) of the basket. As a result, a series of processes is completed.

(Example of registration process for products to be weighed)
FIG. 8 is a sequence diagram showing a flow of registration processing of products to be weighed.
Step S8011: The mobile terminal 50 scans the barcode of the product to be weighed in response to the operation of the customer.
Step S802: The mobile terminal 50 temporarily registers the product to be weighed specified from the scanned barcode, and displays the temporary registration screen.

Step S803: The weighing device 30 displays a standby screen in a standby state in which communication is not connected to the mobile terminal 50. The connection code is displayed on the standby screen.
Step S804: After temporarily registering the product to be weighed, the mobile terminal 50 scans the connection code displayed on the weighing device 30 in response to the operation of the customer.
Step S805: When the mobile terminal 50 scans the connection code, it makes a one-to-one communication connection request to the weighing device 30. Here, if the product to be weighed is not provisionally registered, the mobile terminal 50 does not make a connection request to the weighing device 30 even if the connection code is scanned.

Step S806: When there is a connection request from the mobile terminal 50, the weighing device 30 includes authentication of one-to-one communication and determination of whether the temporarily registered product is a product to be weighed in the weighing device 30. Judge pairing.
Step S807: When the pairing is successful in the determination of pairing, the weighing device 30 starts one-to-one communication with the mobile terminal 50.
Step S808: Further, when the pairing is successful, the mobile terminal 50 starts one-to-one communication with the weighing device 30.

Step S809: The weighing device 30 displays the weighing screen of the temporarily registered product.
Step S810: The weighing device 30 weighs the goods placed on the platform 310 by the customer.
Step S811: When the weighing device 30 finishes weighing, it accepts the operation of the customer and outputs a label indicating the weighing result. The weighing device 30 transmits the weighing result to the mobile terminal 50 when outputting the label.

Step S812: When the mobile terminal 50 receives the measurement result, the mobile terminal 50 displays the measurement result. The timing at which the weighing result is transmitted to the mobile terminal 50 is not limited to the label output timing, and may be the timing at which the weighing device 30 completes the weighing. In this case, the timing at which the weighing result is displayed on the mobile terminal 50 is, for example, the timing at which the weighing is completed on the weighing device 30.

Step S813: The mobile terminal 50 displays the registration update screen, and the main registration of the product to be weighed is completed.
Step S814: The mobile terminal 50 transmits the product information of the product to be weighed obtained from the weighing result and the basket identification information to the cloud server 20.
Step S815: When the cloud server 20 receives the product information and the basket identification information from the mobile terminal 50, the cloud server 20 identifies the basket information including the received basket identification information.

Step S816: The cloud server 20 updates the registered product information included in the specified basket information. Specifically, when the cloud server 20 receives the product information of N items, the cloud server 20 stores the product code included in the product information as the product code of the registered product information (registered product N). Further, the cloud server 20 stores the product code, the product name, and the price in association with each other as product information (registered product N). Further, the cloud server 20 updates the cumulative information (cumulative number of products, subtotal amount, etc.) of the registered product information in the specified basket information.

Although not shown in FIG. 8 for convenience of explanation, the processes of steps S807 to S817 are repeatedly executed for the number of provisionally registered products to be weighed.

(An example of the registration process of the product to be weighed by the mobile terminal 50)
FIG. 9 is a flowchart showing an example of the registration process of the weighing target product performed by the mobile terminal 50. The process shown in the flowchart of FIG. 9 is always (regularly) started at the mobile terminal 50 at a very short time interval.

In FIG. 9, the mobile terminal 50 determines whether or not the barcode of the product to be weighed has been scanned (step S901). If the mobile terminal 50 does not scan the barcode of the product to be weighed (step S901: NO), the mobile terminal 50 proceeds to step S903. When the mobile terminal 50 scans the barcode of the product to be weighed (step S901: YES), the mobile terminal 50 temporarily registers the product to be weighed (step S902). The tentatively registered merchandise to be weighed is displayed on the display 509.

Then, the mobile terminal 50 determines whether or not the connection code has been scanned (step S903). If the connection code is not scanned (step S903: NO), the mobile terminal 50 proceeds to step S909. When the connection code is scanned (step S903: YES), the mobile terminal 50 determines whether or not there is a product to be weighed that is being provisionally registered (step S904). Specifically, in step S904, it is determined whether or not the product to be weighed is stored in the memory 504 as a product being provisionally registered.

When there is no product to be weighed during the provisional registration (step S904: NO), the mobile terminal 50 notifies that the provisional registration is urged (step S905), and ends a series of processes. An example of the notification screen for prompting temporary registration will be described later with reference to FIG. 15 (C). The condition for terminating the notification to prompt the temporary registration is to accept an operation for terminating the notification from the user, an operation for performing the temporary registration, and the like.

On the other hand, when there is a product to be weighed that is being provisionally registered (step S904: YES), the mobile terminal 50 determines whether or not the short-range wireless communication function for performing one-to-one communication is on (step). S906). When the short-range wireless communication function is off (step S906: NO), the mobile terminal 50 notifies the function on (step S907). An example of the function-on notification screen will be described later with reference to FIG. 15 (D). The end condition of the function-on notification is to accept an operation for terminating the notification from the user, an operation for turning on the short-range wireless communication function, and the like.

When the short-range wireless communication function is turned on (step S906: YES), the mobile terminal 50 makes a one-to-one communication connection request to the weighing device 30 (step S908). When the connection request is made, the mobile terminal 50 displays a screen (see FIG. 15A) indicating that the connection is in progress. Then, the mobile terminal 50 determines whether or not the pairing is successful (step S909). When the pairing is successful (step S909: YES), one-to-one communication (pairing) with the weighing device 30 is started (step S910). When the mobile terminal 50 starts pairing, the mobile terminal 50 transmits the identification information of the temporarily registered product to the weighing device 30. Further, an example of a screen at the time of establishing a connection and a screen during weighing will be described later with reference to FIG. 15 (B).

Then, the mobile terminal 50 determines whether or not the error information indicating that the temporarily registered product is not subject to weighing of the weighing device 30 is received within a predetermined time after the pairing is successful (step S911). ). When the error information indicating that the measurement target is not received is not received (step S9111: NO), the connecting process (see FIG. 10) performed during the connection with the weighing device 30 is performed (step S912), and the series of processes is completed. On the other hand, when the error information indicating that the measurement target is not received is received (step S911: YES), the mobile terminal 50 notifies that the measurement target is not applicable (step S913). An example of the notification screen indicating that the object is not subject to measurement will be described later with reference to FIG. 16 (D). Then, the mobile terminal 50 cancels the pairing (step S914) and ends a series of processes.

If the pairing is not successful in step S909 (step S909: NO), the mobile terminal 50 determines whether or not a predetermined time has elapsed after making the connection request (step S915). If a predetermined time has not elapsed after making the connection request (step S915: NO), the mobile terminal 50 ends a series of processes. When a predetermined time has elapsed after making the connection request (step S915: YES), the mobile terminal 50 notifies the user of the retry of the connection request (step S916) in order to prompt the user to perform the operation related to the communication connection again, and a series of steps. Ends the processing of.

An example of the notification screen for retrying the connection request will be described later with reference to FIGS. 16A and 16B. The termination condition of the notification of the retry of the connection request is to accept an operation for terminating the notification from the user, an operation for scanning the connection code again, and the like.

(Processing during connection with the weighing device 30 performed by the mobile terminal 50)

FIG. 10 is a flowchart showing an example of processing during connection with the weighing device 30 performed by the mobile terminal 50. In FIG. 10, the mobile terminal 50 determines whether or not the weighing result has been received from the weighing device 30 by short-range wireless communication (step S1001). When the mobile terminal 50 receives the weighing result from the weighing device 30 (step S1001: YES), the mobile terminal 50 displays the weighing result on the display 509 (step S1002).

Then, when the mobile terminal 50 receives the basket identification information and the product registration update screen information from the cloud server 20, the mobile terminal 50 displays the product registration update screen, and the main registration of the product to be weighed is completed (step S1003). Next, the mobile terminal 50 acquires the product information of the product to be weighed obtained from the weighing result, and transmits the acquired product information and the basket identification information to the cloud server 20 (step S1004).

After that, the mobile terminal 50 determines whether or not all the provisionally registered merchandise to be weighed has been weighed (step S1005). Specifically, the mobile terminal 50 determines whether or not the main registration of all the provisionally registered products to be weighed has been completed. When the weighing of all the provisionally registered products to be weighed is completed (step S1005: YES), the mobile terminal 50 cancels the pairing (step S1006) and ends a series of processes.

When the tentatively registered weighing target products have not been weighed (step S1005: NO), the mobile terminal 50 determines whether or not the communication connection with the weighing device 30 has been disconnected (step S1007). The disconnection of the communication connection may occur, for example, when the distance between the measuring device 30 and the mobile terminal 50 exceeds the possible range of short-range wireless communication. Specifically, the disconnection of the communication connection may occur when the customer goes to another sales floor before the main registration of all the products to be weighed is completed.

When the communication connection with the weighing device 30 is not disconnected (step S1007: NO), the mobile terminal 50 returns to step S1001. When the communication connection with the measuring device 30 is disconnected (step S1007: YES), the mobile terminal 50 notifies that the communication has been disconnected (step S1008). An example of the notification screen indicating that the communication has been disconnected will be described later with reference to FIG. 16 (C). The termination condition of this notification is that an operation for terminating the notification is accepted from the user, communication is reconnected, and the like.

Then, the mobile terminal 50 determines whether or not the communication connection with the weighing device 30 is terminated (step S1009). The termination of the communication connection is, for example, accepting an operation for terminating the connection from the user or continuing the disconnected state for a predetermined time or longer. When the communication connection with the weighing device 30 is completed (step S1009: YES), the mobile terminal 50 ends a series of processes. When the communication connection with the weighing device 30 is not completed (step S1009: NO), the mobile terminal 50 returns to step S1001.

(Example of processing performed by the weighing device 30)
FIG. 11 is an explanatory diagram showing an example of processing performed by the weighing device 30. The process shown in the flowchart of FIG. 11 is always (regularly) started in the weighing device 30 (at a very short time interval).

In FIG. 11, the weighing device 30 determines whether or not it is in the standby state (step S1101). The weighing device 30 displays a standby screen including a connection cord in the standby state. When the weighing device 30 is not in the standby state (step S1101: NO), the weighing device 30 proceeds to step S1104. When the weighing device 30 is in the standby state (step S1101: YES), the weighing device 30 determines whether or not there is a connection request from the mobile terminal 50 (step S1102).

If there is no connection request from the mobile terminal 50 (step S1102: NO), the weighing device 30 returns to step S1101. When there is a connection request from the mobile terminal 50 (step S1102: YES), the weighing device 30 starts one-to-one communication (pairing) with the mobile terminal 50 (step S1103).

Then, the weighing device 30 determines whether or not the temporarily registered product is a product to be weighed in its own device based on the identification information of the temporarily registered product received from the mobile terminal 50 by pairing. Determine (step S1104).

If the temporarily registered product is a product to be weighed in the own device (step S1104: YES), the process proceeds to step S1107. When the temporarily registered product is not the product to be weighed in the own device (step S1104: NO), the weighing device 30 provides error information indicating that the temporarily registered product is not the target to be weighed in the own device. It is transmitted to the mobile terminal 50 (step S1105). Then, the weighing device 30 releases the pairing with the mobile terminal 50 (step S1106). Then, the weighing device 30 performs an in-connect process (see FIG. 12) performed during the connection with the mobile terminal 50 (step S1107), and ends a series of processes.

(Processing performed by the weighing device 30 during connection with the weighing device 30)

FIG. 12 is a flowchart showing an example of processing during connection with the mobile terminal 50 performed by the weighing device 30. In FIG. 12, the weighing device 30 determines whether or not the tentatively registered product has been weighed (step S1201). The weighing device 30 waits until the weighing of the temporarily registered product is completed (step S1201: NO). When the weighing of the temporarily registered product is completed (step S1201: YES), the weighing device 30 displays a print button for outputting the label on the touch panel 306 (step S1202).

Next, the weighing device 30 determines whether or not the print button has been pressed (step S1203). The weighing device 30 waits until the print button is pressed (step S1203: NO). When the print button is pressed (step S1203: YES), the weighing device 30 outputs a label (step S1204). Then, the weighing device 30 transmits the weighing result to the mobile terminal 50 by short-range wireless communication (step S1205).

Then, the weighing device 30 determines whether or not the weighing of all the provisionally registered products has been completed (step S1206). When the weighing device 30 has not completed the weighing of all the temporarily registered products (step S1206: NO), the weighing device 30 returns to step S1201. When the weighing of all the provisionally registered products is completed (step S1206: YES), the weighing device 30 cancels the pairing with the mobile terminal 50 (step S1207). Then, the weighing device 30 shifts to the standby state (step S1208), and ends a series of processes.

In the process shown in FIGS. 11 and 12, the weighing device 30 takes either a standby state or a connected state, but it is possible to take a state other than these. You may. Specifically, for example, it may be possible to take a state in which the setting of the weighing device 30 is changed.

(Regarding the procedure for registering weighing products on the mobile terminal 50)
Next, the procedure for registering the weighing product on the mobile terminal 50 will be described with reference to FIG.
FIG. 13 is an explanatory diagram showing an example of a procedure for registering a weighing product in the mobile terminal 50. FIG. 13 describes an example in which the camera 507 of the mobile terminal 50 captures the identification information of the weighing target product that the customer wants to purchase. It is assumed that, for example, lemon 1301a, apple 1301b, and orange 1301c to be weighed products are displayed in the corner (sales floor) where fruits are placed in the store. Behind each of the goods to be weighed, signs 1302a to 1302c having a display are placed. In the following, the label 1302a will be mainly described as an example, but the same applies to the label 1302b and 1302c.

On the sign 1302a, the characters "lemon", the unit price, and the barcode 1303a are displayed. The unit price is nn yen per kg. The barcode 1303a includes information for identifying the lemon 1301a (product identification information) and a unit price. The barcode 1303a is read by the mobile terminal 50.

The sign 1302a may be printed and posted on paper or the like, or may be displayed on a display. When the sign 1302a is displayed on the display, the content of the barcode 1303a can be changed according to the time. Therefore, for example, it is possible to discount the time service and prevent fraud. Fraud is, for example, taking a picture of the barcode during the time service of the previous day with a camera and having the barcode read the next day to register the product to be weighed at the unit price during the time service of the previous day. Is.

In FIG. 13, the display screen of the mobile terminal 50 shows a screen for temporary registration after the barcodes of lemon and apple are read. Specifically, the mobile terminal 50 displays a product name (product identification information) and displays a screen indicating that each product is not weighed.

More specifically, the display 509 of the mobile terminal 50 displays a subtotal column 550, temporary registration columns 551b and 552b, and a main registration column 553a. In the subtotal column 550, the total amount of the registered products is displayed. In the provisional registration columns 551b and 552b, the provisionally registered merchandise to be weighed is displayed. Specifically, in the temporary registration column 551b, it is displayed that the lemon needs to be weighed (“weighing required”) and that the price is unknown because it is not weighed (“?? Yen”). ing. Similarly, in the provisional registration column 552b, it is displayed that the apple needs to be weighed (“weighing required”) and that the price is unknown because it is not weighed (“?? Yen”). ..

Further, the temporary registration fields 551b and 552b are displayed in a display mode different from that of the main registration field 553a. In the illustration, the temporary registration fields 551b and 552b are displayed in a shaded display mode. By adopting such a display mode, it is possible to emphasize that provisional registration is in progress, so that weighing can be promoted.

In the main registration column 553a, the mainly registered product and the amount of money are displayed. In the main registration column 553a, it is shown that one yogurt of 160 yen is registered. Since the price of the provisionally registered product is unknown, the total price of the product described in the main registration column 553a is displayed in the subtotal column 550.

In addition, a checkout button (“Proceed to checkout” button) is displayed on the right side of the subtotal column 550. When the checkout button is pressed, the checkout will be performed on the registered product.

The screen for registering the product to be weighed may be a dedicated screen different from the screen for registering a normal product that is not the product to be weighed. For example, if the barcode of the product to be weighed is read while the screen for registering a normal product is displayed, the dedicated screen may be displayed. On this dedicated screen, for example, only the products to be weighed can be registered. As a result, it is possible to clarify that the product to be weighed has been provisionally registered and that the merchandise needs to be weighed.

Here, when the barcode of the normal product is read on the dedicated screen, the control may be a control for prohibiting the registration of the normal product or a control for permitting the registration. In the control prohibiting the registration, for example, when the barcode of a normal product is read while the dedicated screen is displayed, "Please weigh the product to be weighed first" may be displayed. As a result, it is possible to prevent the customer from forgetting to weigh the tentatively registered merchandise to be weighed. Further, the condition for canceling the prohibition of the registration may be the completion of the main registration of the measurement target product or the acceptance of the customer's operation for canceling the provisional registration of the measurement target product.

Further, in the control for permitting the registration, when the barcode of the normal product is read while the dedicated screen is displayed, the screen may return to the screen for registering the normal product. Further, after returning to the screen for registering a normal product, it may be notified that there is a product to be weighed that is being provisionally registered, for example, a display of "There is a product requiring measurement" on the screen. As a result, it is possible to prevent the customer from forgetting to weigh.

(About the standby screen of the weighing device 30)
Next, an example of the standby screen displayed on the weighing device 30 will be described with reference to FIG.
FIG. 14 is an explanatory diagram showing an example of a standby screen displayed on the weighing device 30. As shown in FIG. 14, the touch panel 306 displays a standby screen 1400 displayed in the standby state. The first guide column 1410 and the second guide column 1420 are displayed on the standby screen 1400. The first guidance column 1410 shows guidance when registering a product to be weighed using the mobile terminal 50. Specifically, the two-dimensional code 1411 is displayed in the first guide column 1410, and a guide for causing the mobile terminal 50 to read the two-dimensional code 1411 for connection is displayed.

The second guide column 1420 shows a guide when the product to be weighed is registered without using the mobile terminal 50. Specifically, in the second guide column 1420, a guide for placing the product on the scale and encouraging weighing is displayed. Hereinafter, a case where the mobile terminal 50 is used will be described.

As shown in FIG. 13, when the temporary registration of the lemon and the apple in the mobile terminal 50 is completed, the customer causes the mobile terminal 50 to read the two-dimensional code 1411 for connection. Even after the temporary registration is completed, the mobile terminal 50 still displays the same screen as when reading the barcode of the product. Therefore, the customer can have the mobile terminal 50 read the two-dimensional code 1411 for connection without performing the operation of switching the screen.

The mobile terminal 50 that has read the connection two-dimensional code 1411 requests the measuring device 30 to make a communication connection based on the instruction indicated by the connection two-dimensional code 1411. As a result, the mobile terminal 50 and the weighing device 30 start one-to-one communication. When the communication is established, the mobile terminal 50 transmits the information of the product temporarily registered in the weighing device 60. For example, when the lemon and the apple are provisionally registered as shown in FIG. 13, the mobile terminal 50 transmits the identification information between the lemon and the apple.

The weighing device 60 that has received the product identification information controls the touch panel 306 so as to display a screen prompting the weighing of the product to be weighed indicated in the identification information. In the present embodiment, the touch panel 306 is controlled so as to display a screen prompting the weighing of the product to be weighed according to the order in which the identification information is acquired by the mobile terminal 50.
