<Outline explanation of the embodiment>
Prior to describing the details of the embodiments below, an overview of the modes disclosed herein will be described below.
There are at least a first mode and a second mode in the disclosed technique. In addition, it does not exclude the existence of other modes such as the standby mode described later.

<Overview of the first mode>
The first mode is a mode in which the mobile terminal 30 held by the operator is used when the product is weighed by the weighing device 10 and the product is purchased. By using the mobile terminal 30, it is possible to store the products sold by weight to be purchased in a virtual shopping cart. The operation of this mode 1 is realized by the mobile terminal 30, the weighing device 10, the tag device 20 installed for each type of product, and the like operating in cooperation with each other.

The mobile terminal 30 can also be used to register purchased products other than the products sold by weight in a virtual shopping cart. Therefore, it is possible to use the mobile terminal 30 for purchased products including products sold by weight. As a result, the purchaser who operates the mobile terminal 30 can easily and quickly purchase the product, for example, the settlement process can be performed quickly.

<Overview of the second mode>
The second mode is a mode in which an operator selects a product by operating the tag device 20 without going through the mobile terminal 30, and the operator operates the weighing device 10. .. Needless to say, even when the operator does not operate the tag device 20, the operation in the second mode can be performed.
The details of the tag device 20 will be described later. For example, the device shown by the tag device 20-1 to the tag device 20-N in FIG. 2 is an example, and the operator who purchases a product sold by weight is the second. The outline of the procedure to be executed in the mode is as follows.

First, the operator puts the required quantity of products to be purchased in the required quantity bag. At that time, the display screen of the tag device 20 installed on the product sold by weight is touched. By touching the display screen in this way, the product information of the product is transmitted from the tag device 20 to the weighing device 10.

When the operator weighs the weighed product put in the bag in the weighing device 10, the icon of the product corresponding to the product information already transferred from the tag device 20 is displayed on the screen of the weighing device 10. .. The operator appropriately calculates the amount of the weighed product by touching the icon of the product placed on the mounting table among the displayed product icons. A label on which a symbol code or the like containing the calculated amount of money information is printed is output from the weighing device 10. The operator attaches the output label to the bag containing the weighing product. When the operator makes a payment at a POS terminal or the like, the POS terminal is made to read the symbol code printed on the label.

By going through the above procedure, the weighing device displays the product icon corresponding to the tag device 20 touched by the operator, so that the appropriate product icon is displayed on the weighing device 10. .. When a plurality of operators touch the tag device 20, it is assumed that the icon of the product corresponding to the tag device 20 touched by another person is displayed. The measures for this will be described in detail in the embodiments described below.

The outline of the first mode and the second mode is as described above, but when the operator uses the weighing device 10, even if the operation in the first mode can be performed, the second mode is used. It is desirable that the store system can respond flexibly, assuming that the operation is performed in the above mode.

Therefore, as will be described later, when the weighing device 10 is operated, even an operator who purchases the product in the first mode operates the weighing device 10 in the second mode. It should be noted that it is permissible to do so.

Further, as will be described later, for example, the code on the screen of the weighing device 10 is read to shift to the first mode in which the weighing device 10 and the mobile terminal 30 communicate with each other, or the weighing device 10 itself is operated to perform a second mode. When shifting to the mode, it is desirable that the earlier operation (interaction) of the operator is prioritized.

The above is the outline of the mode in the embodiment disclosed in this application. It should be noted that the above description is a summary description and is not intended to limit each embodiment.

According to the disclosed embodiment, the weighing device displays product selection related information (for example, an icon button for selecting a product) according to the received product identification information. In addition, what is displayed includes product selection-related information of the product corresponding to the terminal device operated by the operator who operates the weighing device. Therefore, even if there are many types of products, it is possible to easily find the desired product from the displayed product selection-related information.

In addition, by linking with the tag device 20 (terminal device), the user interface displayed on the display screen of the weighing device becomes more stable, and the weighing device can be appropriately adjusted without confusing the first operator. It can be operated quickly.

<Embodiment 1>
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a system configuration diagram of a product sales system according to an embodiment.

In FIG. 2, product tag devices (20-1, 20-2, 20-N) are installed in each of the product groups (40-1, 40-2, 40-N) in the sales floor, and the vicinity of the product group. It shows how the weighing device 10 is installed in.

This product sales system is installed in a supermarket that sells fresh foods such as vegetables and fruits. In the fresh food section of the supermarket, as shown in FIG. 2, products 40-1 to 40-N such as vegetables and fruits sold separately are classified by type and displayed at each display place 50. Further, for each display location, tag devices 20-1 to 20-N (terminal devices) are provided corresponding to the products at the display location. Since each product is sold separately, a label with a price or barcode printed on it is not affixed, and the operator packs as many products as necessary in a bag such as vinyl and weighs them with the weighing device 10. Labels for the products to be purchased are issued from the weighing device 10. Then, the operator attaches this issued label to a plastic bag filled with the product, and since the label has a symbol code containing information such as price printed on it, the product must be registered on the POS terminal 32 or the like. Can be done. Further, by using the mobile terminal, the operator can register the price of the weighed product without using the POS terminal, and can quickly shop.

Each tag device 20 (terminal device) is provided with a display touch panel, and when the display touch panel is operated (touched) by an operator, the tag device 20 stores a PLU (Price Look Up) code (or product). Identification information) is transmitted to the weighing device 10. This PLU code is a product identification number (instruction information) that identifies the type of product, and indicates the product associated with the tag device 20. When packing a product to be purchased in a plastic bag, the operator performs the above touch operation on the tag device 20 corresponding to the product. In this way, the PLU code of the product to be weighed by the weighing device 10 is transmitted from each tag device 20 to the weighing device 10. The operation of the operator is not limited to touching the touch panel. For example, the operation may be such as touching the housing of the tag device 20 or pressing a button provided on the tag device.

Further, the display touch panel of the tag device 20 (terminal device) can display a symbol code including the PLU code of the stored product. The operator holding the mobile terminal can read this symbol code through the camera of the mobile terminal. The read PLU code may be sent to the weighing device 10 by short-range wireless communication established between the mobile terminal 30 and the weighing device 10. Alternatively, the PLU code may be transferred from the mobile terminal 30 to the weighing device 10 via the wireless LAN (or public telephone line, etc.) via the store controller 31.

The tag device 20 and the weighing device 10 are connected to each other so as to be able to communicate with each other by a wired LAN or a wireless LAN. All the devices shown in FIG. 1 may be connected by a single LAN or a wireless LAN.

The weighing device 10 receives the PLU code from the tag device 20 and displays a product icon (product selection related information) corresponding to the received PLU code on the screen of the display touch panel 104. If there are multiple received PLU codes, they are displayed on the screen. Further, the weighing device 10 weighs the product placed on the weighing unit (scale) and stores product data such as the unit price of the product corresponding to the icon selected by the operator on the display touch panel (RAM). ) To calculate the price of the product and issue a label.
In addition, the printing unit 110 outputs the calculated price of the product and a label on which the barcode is printed, if necessary.
The weighing unit 109 including the mounting table measures the weight of the product mounted on the mounting table.

The POS terminal 32 and the self-POS terminal 33 (product registration device) are so-called cash registers, and are products purchased by the operator (including fresh foods weighed by the weighing device 10 and products with a label attached in advance). Perform product registration and payment. Further, the POS terminal 32 and the self-POS terminal 33 are also payment devices for settling the price for which the product is registered on the mobile terminal 30. The POS terminal 32 is operated by a clerk, and the self-POS terminal 33 is operated by the operator himself. The product identification number such as the PLU code and the price information according to the weight in the case of the label issued by the weighing device 10 are printed in the form of a barcode on the product label, and the POS terminal 32 and The self-POS terminal 33 includes a reader for reading these barcodes. Then, the POS terminal 32 and the self-POS terminal 33 perform the product registration process based on the barcode information read by the reading device and the information such as the product selling price stored in the memory.

Further, the mobile terminal 30 also has the functions of the above-mentioned POS terminal, and the operation of the POS terminal by the operator or the clerk can be omitted by performing electronic payment or the like by the mobile terminal alone. Therefore, the operator holding the mobile terminal can quickly shop.

The store controller 31 is a computer that manages various data in a supermarket, and is connected to a weighing device 10, a POS terminal 32, a self-POS terminal 33, and a mobile terminal 30 by a LAN (Local Area Network), a wireless LAN, or the like. .. As various data, for example, a product file storing information such as a product selling price stored in the POS terminal 32 and the self-POS terminal 33, a PLU file (see FIG. 8) described later stored in the weighing device 10, the POS terminal 32, and the POS terminal 32 There is a record file transmitted from the self-POS terminal 33.

FIG. 3 is a diagram showing reading of a product type and the like by the mobile terminal 30.

FIG. 3 shows an example in which the mobile terminal 30 is used to acquire the type of merchandise sold by weight that the operator wants to purchase. In FIG. 2, lemon 40-1, apple 40-2, and orange 40-N are displayed, and a tag device 20-1, a tag device 20-2, and a tag device having a display behind each of the products sold by weight are displayed. 20-N is placed.

In FIG. 3, for example, the tag device 20-1 indicates that the characters of lemon, the unit price is per kg, and the unit price is nn yen. In addition, a barcode is displayed so that the mobile terminal 30 can optically read the information. This barcode is read by the camera of the mobile terminal 30 and displayed as the barcode 301 on the display. The display on these tag devices 20 may be displayed in a state of being printed on paper or the like. By displaying using a display, it is possible to quickly display with a discount at the time of time service or the like. In addition, by changing the barcode at a predetermined time and displaying it, the mobile terminal 30 can read the barcode or the like taken by the camera in advance, so that the products sold by weight can be registered at different unit prices. It can also prevent fraud.

It can be seen that the mobile terminal 30 in FIG. 3 is equipped with a camera and the barcode 301 of the lemon 40-1 is read. In the display area of the mobile terminal, the read "lemon" 321 is displayed, the "weighing required" 325 is displayed, and the subtotal column? ?? ?? Circle 315 and the like are displayed.

In addition, in the subtotal column 315, is there one registered product, and what is the approximate total? ?? ?? It is a yen, and a button to proceed to checkout is displayed. Since the measurement value of the lemon has not been obtained, the measurement required 325 has been notified, and the operator is urged to perform the measurement. Also, because it is not weighed? ?? A circle is displayed. Further, the column 321 of the merchandise sold by weight that has not been weighed is shaded, and is displayed in such a manner that the operator can recognize that the weighed value is not made.

The PLU code (product identification information) is received by the receiving unit 401 in response to the interaction between the operator and the tag device 20, such as when the operator touches the touch panel of the tag device 20 (terminal device). Touching the touch panel is an example of interaction. The interaction is not limited to this, for example, pressing a physical button installed on the 20th, imaging a symbol code including the displayed product identification code with a smartphone, and a weighing device capturing the product identification code via the smartphone. Another example of interaction is for the smartphone to read the symbol code of the tag device when receiving it.

The mode reception unit 403 receives a mode instruction in response to an interaction such as an operation on the weighing device by the operator. The mode includes at least a first mode in which the operator's mobile terminal intervenes and a second mode in which the mobile terminal does not intervene. It is desirable that the weighing device 10 display a standby mode screen on which information on the first mode and information on the second mode are displayed. FIG. 9 is an example of a screen in the standby mode. When the operator causes the mobile terminal 10 to read the symbol code of the standby screen, the mode reception unit 403 can receive the instruction of the first mode.
When the operator touches the lower part of the standby screen 104b or puts the product on the mounting table, the mode reception unit is instructed of the second mode.

The measuring unit 405 measures the weight of the product placed on the mounting table.

Upon receiving the printing instruction, the output unit 409 prints the price of the product and, if necessary, on a label, for example. The price of the product is calculated based on the weight of the product received from the weighing unit, the PLU code received from the display control unit 407, the unit price information stored in advance, and the like. When the unit price is set by the number of apples, etc., the number is estimated and the product price is calculated.

What is output from the output unit is not limited to a label, but may be affixed to a weighed product, a product displayed on a bag containing the product, or the like. In the first mode in which the mobile terminal is interposed, the bar code does not have to be printed on the label if the price information is transferred to the virtual shopping cart on the spot. In this case, the operator may make a payment with the self-POS terminal 33 capable of making a payment for the product registered in the mobile terminal 30, or may make an electronic payment with the mobile terminal 30 itself without going through the POS terminal 33. good. In the case of electronic payment, the operator may be urged to make electronic payment in the vicinity of the exit of the store or in a specific area near the exit.

In the case of a normal operator who does not have a mobile terminal, it is desirable to print a label containing information including the price of the product. The operator attaches the printed label to the product bag. The bar code on the attached label is read by a POS terminal or the like at the time of payment, and payment is made.

FIG. 8 shows an example of a PLU file.

The PLU file is a file that stores data of each item of the PLU code, product name, unit price, weight, bulk purchase amount, and icon name for each product to be weighed by the weighing device 10, and is created by the store controller 31. , It is transmitted to the weighing device 10 and stored in the RAM 103.

Here, the weight data is a value set as an average value per product, and is data used for calculating the number of products from the weight value measured by the weighing device 10. Therefore, this data is set only for mass-selling products such as apples. In the case of products that are not sold by quantity, for example, products that are sold in grams such as meat, the price is calculated using only the unit price data (gram unit price). As the unit price data, an amount per piece is set for a quantity-selling product, and an amount per 100 grams is set for a gram-selling product, for example.

FIG. 9 is a diagram showing a display touch panel of the weighing device 10. As shown at the bottom of the initial screen 104b of the display touch panel, "Please put the product on the scale" is displayed (104c). The initial screen is an example of the standby mode state. At the top of the screen, an explanation for operating the weighing device with the smartphone application is displayed. When the operator places the product, a screen displaying an icon for selecting the product may be displayed. Alternatively, even if the operator touches the screen of the weighing device 10, the same operation as when the product is placed may be performed.

When the operator reads the symbol code (the symbol code is an example of the first symbol code) using the mobile terminal 30, the mode shifts to the first mode described in detail below. When the operator places the product on the mounting table, the mode shifts to the second mode described in detail below. The method of transitioning this mode is an example. For example, if the operator touches the smartphone or the symbol code part, the mode may be changed to the first mode. Further, if the operator touches the lower part 104c of the screen, the mode may be changed to the second mode.

FIG. 10 is a flowchart showing the operation of switching between these modes. The operation will be described below.

[S1001] In step S1001, the mode switching selection screen or other screen is displayed on the touch screen of the weighing device. The process proceeds to step S1002.
[S1002] In step S1002, it is checked whether or not the initial screen on which the mode can be switched is displayed. On the initial screen, the outline of the two modes is displayed, and it is desirable that the operator can grasp the contents of the modes. If this determination is No, step S1002 is repeated again. If this determination is Yes, the process proceeds to step S1004.

[S1004] In step S1004, it is checked whether or not the symbol code of the screen has been read by the mobile terminal held by the operator. Instead of reading the symbol code on the screen, it may be checked whether communication with the weighing device has been established by NFC. If this check is Yes, the process proceeds to step S1012 to operate the weighing device in the first mode using the mobile terminal. The details of the first mode will be described later. If checked or no, the process proceeds to step S1006.

[S1006] In step S1006, it is checked whether the product is placed on the mounting table. The fact that the product is placed on the mounting table is very likely to indicate that the operator does not have a mobile terminal and operates the weighing device manually. Therefore, if this determination is Yes, the process proceeds to step S1010 in order to shift to the second mode. As described above, even when the operator touches the screen in order to explicitly process the manual, the process can proceed to step S1010. If this determination is No, the process returns to step S1002.

[S1010] The first mode is executed in step S1010. The details of the first mode will be described later. When the first mode ends, the process returns to step S1001.
[S1012] The second mode is executed in step S1012. The details of the second mode will be described later. When the second mode ends, the process returns to step S1001.

<Contents of the first mode>
The contents of the first mode will be described below. The first mode is a mode in which a product is selected by an operator operating the tag device 20 via a mobile terminal, and the operator operates the weighing device 10.

FIG. 11 is a diagram showing a mode of interconnection between the mobile terminal 30 and the weighing device 10.

FIG. 11A is a diagram showing how the camera of the mobile terminal 30 reads the symbol code 56a displayed on the weighing device 10. The captured symbol code 56b is displayed on the screen of the mobile terminal 30.

The mobile terminal 30 analyzes the symbol code and acquires information necessary for mutual communication. Using this information, the communication device 344 of the mobile terminal 30 and the second communication unit 108 of the weighing device 10 can establish mutual communication by using short-range wireless communication such as Bluetooth (registered trademark). .. The symbol code displayed on the mobile terminal 30 may be read by the imaging unit 111 of the weighing device 10 to establish mutual communication, or NFC may be used to acquire information necessary for mutual communication. .. After mutual communication is established, not only short-range wireless communication such as Bluetooth (registered trademark) but also other wireless communication such as Wi-Fi, optical communication, wide area communication network of mobile phones, etc. can be used together. Good.

FIG. 11B shows a situation when mutual communication is established and the information of the merchandise sold by weight registered by the mobile terminal 30 is transferred to the weighing device. The information on the products sold by weight registered by the mobile terminal 30 may be directly transmitted from the mobile terminal 30 to the weighing device 10 by mutual communication, but other communication-connected POS terminals 32, store controllers 31 and the like may be transmitted. Needless to say, it may be transmitted to the weighing device 10 via an apparatus and a server device (not shown).

In FIG. 11B, the display screen 60a of the weighing device 10 is largely shown as the display screen 60b. The same display screen 60b may be displayed on the screen of the mobile terminal 30. By displaying the display screen 60b of the weighing device 10 on the mobile terminal 30 in this way, the operator can give an instruction to the weighing device 10 from the mobile terminal 30. Needless to say, the mobile terminal 30 may display the product registration screen without displaying such a screen.

As shown in the mobile terminal 30 of FIG. 11A, apples and lemons, which are products sold by weight for which a measured value has not yet been acquired, are displayed. The reason why these two products sold by weight are displayed is that the types of these products are obtained through the camera of the mobile terminal 30 by reading the barcodes of the apple and lemon of the tag device 20. In order to encourage the operator to select a product and weigh each of the apples and lemons held by the operator, a notification is given that "Please select a product and place the product on the table".
In the case of the mode via the mobile terminal (first mode), it is desirable to display only the icon indicating the type of the product read by the operator's mobile terminal.

Touch the tag device 20 before switching to the first mode or after switching to the first mode by the type of product read by another operator's mobile terminal or, as will be described later, by an operator who does not have a mobile terminal. It is desirable not to display the type of icon corresponding to the product. This is because the icon of the product that another person is trying to purchase is not displayed so as not to confuse the operator using the mobile terminal. By doing so, it is possible to speed up the purchase process of the operator who purchases the merchandise sold by weight via the mobile terminal. The information that another operator touches the tag device 20 in the first mode is stored in, for example, the RAM 103 of the weighing device 10.

Alternatively, at least immediately after the first mode is started, it is desirable to display only an icon indicating the type of product read by the operator's mobile terminal. After that, the restrictions on the icons to be displayed may be relaxed.

The search icon for searching for a product may not be displayed on the display screen 60b. This is because the operator has already read the symbol code of the product displayed on the tag device 20 by the mobile terminal 30. It is also assumed that the operator forgets to read the symbol code of the product by the mobile terminal 30. In such a case, the product search may be performed by touching the help key (not shown).

Further, the button 66 for stopping the weighing may be displayed.

FIG. 12 is a diagram for acquiring a measured value of a product sold by weight. In FIG. 12A, the operator first touches the apple button 63 on the display screen 60d. It is shown that the apple button 63 is highlighted by touching the apple button 63 on the screen of the weighing device with the operator's finger 100. By this operation, the display control unit 407 of the weighing device 10 detects that the apple is weighed. Then, the display screen displays that the unit price of the apple is 360.00 yen / kg. This unit price is obtained by the weighing device, for example, from the product master of the store in advance, or in response to the operator selecting the apple of the product sold by weight, the unit price of the apple is acquired from the product master. , Can be displayed.

In FIG. 12B, the display screen 70a of the weighing device 10 is enlarged and shown as the display screen 70b. On the enlarged display screen 70b, the notification "Please put the product" 73 is made, and the operator is urged to put the apple on the mounting table 62. In addition, the apple display 75 is displayed so that the operator can easily understand it. The back button 77 is a command button for returning to the previous screen and displaying the previous display screen. If the product has already been placed, the notification of "Please put the product" 73 does not have to be given.
In response to this display, the operator is trying to place the apple 80 on the platform 62 by the operator's finger 100.

FIG. 13 is a diagram showing a state of weighing. In FIG. 13A, since the apple 80a is placed on the platform 62, the display screen 90a (90b) shows that the measured value is 1.2006 kg, the unit price is 360.00 yen, and the measured value. Based on the unit price, it is shown that the total amount of apples is 432 yen. The total amount may be calculated by rounding down to the nearest whole number.

A label print command button 93 is displayed on the display screen 90b. It is desirable that the print command button 93 is displayed only when the product is placed and the measured value becomes stable. Alternatively, the print command button 93 is darkened until the measured value stabilizes so that printing is not performed even if it is pressed. When the measured value stabilizes, it is displayed brightly, and when it is pressed, printing is performed. May be good. In addition, a notification "Please press the print button" is given. After confirming that the operator's operation is correct, the operator touches the print command button 93 with the operator's finger 100.

FIG. 13B shows the display screen 95 after the print command button 93 is touched. When the label 97 is printed from the weighing device 10a, the display screen 95 is notified to prompt the user to attach the label 97 to the product bag 81. The label may not be printed out. Further, the label may not be printed with a symbol code including information on the measured value. It is desirable that the product type and the measured value are transferred from the communication means 333 of the weighing device 10 to the mobile terminal via the communication means 215 of the mobile terminal 30 by using mutual communication. Further, the weighing device 10 may transmit the product type and the weighing value (and price) so as to be stored in the basket of the operator provided in the other higher-level device of the store via the communication line. If the price etc. is stored in the basket, it is desirable not to print the symbol code including the price etc. on the label. FIG. 13B is a screen of the weighing device 10, but the label 97 on which the symbol code is not printed is displayed on the printed label. Even when it is actually printed, it is desirable not to print the symbol code including the price and the like. This is because the price of the product is already stored in the basket. An example of label 97 in FIG. 13 (B) is shown in FIG. 25 (A).

FIG. 14 is a diagram showing a display screen 60e of the weighing device 10 and its operation after the measurement value is acquired. As shown in FIG. 14 (A), the display of the apple disappears in the region 63a. This is because it is not necessary to display the apple because the weighed value of the apple has already been obtained and the label has been printed out.

FIG. 14B shows an example in which the button 66 for stopping weighing is touched by the operator's finger 100. Since the lemon display 65a remains on the display screen 60f, the operator is required to weigh the lemon, but even in such a situation, based on the operator's will, Weighing can be stopped.

FIG. 15 is a flowchart showing a linking operation between the mobile terminal 30 and the weighing device 10. The details of this flow will be described below.

[S2002] The mobile terminal 30 reads the symbol code of the product sold by weight. By this operation, the mobile terminal acquires the type of the product sold by weight. The acquired product type is registered in the mobile terminal and displayed on the screen. At this stage, the measurement value of the weighed goods has not been acquired, so the transition to the settlement process is prohibited. It should be noted that the operator operating the mobile terminal may be allowed to press the button for proceeding to accounting. In this case, it is sufficient to urge the goods whose weighing value has not been obtained to be put in the holding basket.

The hold basket is a basket in which, for example, products that require the intervention of a clerk at the time of payment are placed separately from other ordinary products. The settlement process with the intervention of a clerk can be carried out quickly by providing an area for storing the reserved products by attaching it to a normal basket or by making a partition in the basket. It is not always necessary to provide a holding basket. In addition, it is desirable to notify "weighing required" to acquire the measured value and notify to acquire the measured value. The process proceeds to step S2004.

[S2004] It is checked whether the work of acquiring the type is completed. This check gives a positive judgment (yes) when a confirmation operation such as pressing the "reading complete" button (not shown) is performed after the mobile terminal 30 has read the symbol code of the product sold by weight. (It is not always necessary to provide this "reading complete" button). In this case, the process proceeds to step S2006. In other cases (such as when the button to proceed to accounting is pressed), a negative judgment (no) is automatically made, and the process returns to step S2002. When the operator causes the mobile terminal 30 to read the symbol code of the weighing device 10, the process proceeds to S2006.

[S2006] Information on mutual communication with the weighing device is acquired. That is, the symbol code of the weighing device is read by the mobile terminal 30. The mobile terminal may acquire the connection information by connecting by NFC, reading the symbol code displayed on the mobile terminal by the weighing device, or the like. The process proceeds to step S2008.

[S2008] Mutual communication is established with the weighing device. The mobile terminal 30 and the weighing device 10 occupy short-range wireless communication such as Bluetooth (registered trademark). The process proceeds to step S2010.

[S2010] The operator operates the weighing device to acquire the weighing value. Alternatively, using a mobile terminal with established mutual communication, the weighing device may acquire the weighing value in response to an operation by the operator using the mobile terminal 30. The mobile terminal 30 acquires the measured value from the measuring device 10 and registers it. The mobile terminal 30 may change the display mode of the column of the product for which the measured value has been acquired so that it can be known that the measured value has been acquired. Alternatively, the price may be calculated from the measured value and the unit price and displayed. The process proceeds to step S2012.

[S2012] It is checked whether or not the measured values of all the acquired product types to be weighed have been acquired. If this check is negative (no), the process returns to step S2010. If this check is affirmative (yes), the process proceeds to step S2014.

[S2014] The prohibition on the transition to the settlement process is lifted. Then, mutual communication is disconnected.
This completes the linking operation between the weighing device 10 and the mobile terminal 30.

In a state where the mobile terminal 30 and the weighing device 10 are connected by Bluetooth (registered trademark) or the like (connection method using radio waves such as Wi-Fi, NFC, etc.), the operator can, for example, connect to the weighing device 10. If nothing is done for a certain period of time, a timeout may occur and the connection between the mobile terminal 30 and the weighing device 10 may be disconnected. In such a case, it can be estimated that the operator has left while the weighing device 10 and the mobile terminal 30 are connected. Then, by forcibly terminating the process by the time-out, it is possible to enable the next operator (customer) to use the weighing device 10.

<Contents of the second mode>
The contents of the second mode will be described below. The second mode is a mode in which an operator selects a product by operating the tag device 20 without using a mobile terminal, and the operator operates the weighing device 10.

FIG. 16 is a diagram showing an icon table corresponding to a product selected by an operator who touches the tag device 20 without going through the mobile terminal 30. This icon table may be created and stored in the RAM 103 of the weighing device 10. Data of each item such as PLU code, icon counter, time memory, display priority, selectable, etc. are stored in the icon table. This icon table is used for managing the product icons displayed on the screen of the display touch panel 104 by the weighing device 10. Here, the number of icons that can be simultaneously displayed on the display touch panel 104 is limited. The icon table shows up to 4 entries, but it is desirable to design it to have more entries. Each number indicates, for example, the order in which the icons are displayed from the upper left of the screen of the display touch panel 104.

Specifically, when the weighing device 10 receives the PLU code from the tag device 20, it determines whether the PLU code exists in the icon table, and if it does not exist, adds a new PLU code to an empty entry and displays the icon. Set the value of the counter to "1" and set the value of the time memory to that time. Then, for example, when the operator starts to operate the weighing device, the priority 1 is set for the existing entry, the selectable field is set to 1, and each icon is displayed.

Then, when the PLU code is received by another operator touching the tag device 20 while the operator is operating the weighing device, the entry is added to the icon table. At that time, for example, the priority setting of the icon may be set to 0 to prohibit the display of the icon so as not to cause confusion to the operator. Alternatively, the entry with priority 0 may be grayed out, the icon may be reduced in size, or may be blinked. Further, for example, by setting 0 in the selectable field, the operator may not be able to select.

Alternatively, if the icon is already displayed, the value of the displayed icon counter may be incremented. The value of the counter may be displayed on the icon on the screen as well.

Further, the icon table may include an entry of the operator via the mobile terminal described above. In this case, the predetermined icon to be displayed when the predetermined operator is operating may be specified by storing the operator's identification code and the like together.

If the received PLU code exists in the icon table, the value of the icon counter of the entry in which the PLU code already exists is incremented by one, and the value of the time memory is set to the time at that time. Then, in this case, if the icon of the product is already displayed, the display on the screen is not changed (only the value of the counter may be updated).

When the PLU code of the entry whose priority is not 1 is received again, the value of the icon counter of the entry in which the PLU code exists is incremented by one, and the value of the time memory is set to that time. In this case, the display mode of the icon may be maintained.
In this way, each time the PLU code of the same product is received, the numerical value of the icon counter is incremented by 1.

Then, for example, the display priority of all the entries registered in the icon table is changed to 1 until the operator finishes the operation and the next operator operates the weighing device. As a result, the icon currently entered in the icon table is displayed when the operator operates the weighing device.

It goes without saying that the above display priority, the set value in the selectable column, and the display mode are examples, and other display modes may be set.

In addition, if the time of the icon is earlier than the predetermined time from the current time, it is presumed that the operation error is made by the operator. Is desirable.

Further, in the weighing device 10, when the icon displayed on the screen of the display touch panel 104 is selected by the operator, the corresponding product is weighed and the label is issued, the entry of the PLU code of the product in the icon table is performed. Decrease the value of the icon counter by one. Then, when the numerical value of the icon counter becomes "0" as a result, the entry is deleted from the icon table and the icon of the product is deleted from the screen. If the value of the icon counter is not "0", the entry is not deleted and the icon is not deleted.

In this way, the icon counter represents the number of operators who have not yet weighed the product, and the icon of the product is displayed on the screen of the display touch panel 104 until the icon counter becomes "0". Continue to be done.

As described above, the period during which the operator (operator) is in the process of operating the weighing device is treated as the period from when the operator places the product to when the label is printed out.

However, if the operator remains in front of the weighing device, it is likely that a plurality of products will be weighed. It may be determined that the operation of the operator is continuing until the operator leaves the weighing device, and the display mode of the icon may be maintained as it is. For example, by providing a motion sensor in the weighing device to detect whether the operator has left, or by recognizing the operator's face and detecting whether the same operator is in front of the weighing device. , It may be detected whether the operation of the operator is completed. Alternatively, if it is not placed on the weighing device 10 for a predetermined time, it may be recognized that the operation of the operator has been completed.

FIG. 17 is a diagram showing a state when the operator places the product on the weighing device. As shown in FIG. 17 (A), the operator places the product apple 40-1.

As shown in FIG. 17B, when the product is placed, the weight is calculated and displayed as 0.3606 kg as shown on the display touch panel 104c. Then, the explanation "Please select a product" is displayed. In addition, the apple icon 104P and the lemon icon 104Q are displayed. These icons are displayed because the operator has already touched the apple and lemon tag device 20.

At the time when the product is placed, the image pickup unit 111 may not start recognizing the placed product. This is because the display touch panel 104c of the weighing device 10 usually displays a candidate icon to be selected by the operator. When the icon is not displayed on the display touch panel 104c, or when the search key 104Y is touched by the operator as described later, the icon corresponding to the product candidate recognized by the imaging unit 111 is displayed. You may let it.

The button 104X for stopping the weighing and the search key 104Y for selecting another product may be displayed.

If the stop button 104X is touched during the operation of the operator, the screen returns to the standby screen (for example, the previous screen), the selected icon is deselected, and the displayed icon is not cleared. The screen may be displayed until a predetermined time has passed. After a predetermined time has passed, for example, the initial screen of FIG. 9 may be displayed.

Alternatively, as shown in various modifications described later, when the cancel button 104X is touched while the icon is displayed in a different display mode on a certain screen, the standby screen (for example, the figure). When the operator returns to the screen of 9) and proceeds with the operation again, all the icons may be displayed in the same display mode.

Further, when the search key 104Y is touched, the product placed on the imaging unit 111 may be pattern-recognized in a non-contact manner so that the product can be searched based on the pattern recognition result (not shown:). Product recognition department). Then, the recognition candidate may be selected. Alternatively, the weighing device may display a character input key so that the operator can search for the product by inputting a part of the product name. When there are a plurality of search result candidates, the operator may be presented with the plurality of candidates on the display screen to prompt the operator to make a selection.

Further, when the search key 104Y is not displayed and the operation of the operator elapses for a predetermined time, the search key 104Y may be displayed. Immediately after the second mode is switched, the icon of the product entered after the mode is switched may not be displayed.

Further, when the weighing and label printing of even one product is completed, the operation completion button (FIGS. 20, 104Z) for declaring that the operation of the first operator is completed is displayed on the screen of the weighing device. You may. When the operator presses the operation completion button (FIGS. 20, 104Z), the screen returns to the standby screen in the same manner as the cancel button 104X, and all the icons corresponding to the products selected by the operator may have the same display mode. ..

FIG. 18 is a diagram showing an example of product selection in the weighing device. As shown in FIG. 18A, the operator has selected the apple icon 104P.

On the screen 104e of FIG. 18B, the unit price of one apple is 120 yen, and it is shown that the total is 360 yen. In addition, the print button 104T is displayed. In addition, the back button 104S is displayed.

The first operator is also on the screen of FIG. 18 (B), or on the screen for instructing printing of the label described later or the screen for explaining printing (screen of FIG. 19 (A) or (B)). A set of icons that could be touched by the user may be displayed in a small size on a part of the screen so that the icon can be selected and instructed. By doing so, it is possible for the operator to press the icon and replace the product data in the middle of the operation. By performing such a display, even if an operation error is made, the correct product can be reselected without returning to the screen of FIG. 17B, for example.

FIG. 19 is a diagram showing how the label is printed. As shown on the screen 104f of FIG. 19A, the operator touches the print button 104T in order to purchase the displayed product. By this operation, the label is printed.

In FIG. 19B, guidance for attaching the label L to the product bag is displayed on the screen 104g. The operator may attach the printed label to the product bag according to this guidance. It can be seen that the label is printed with the symbol code L1 including the price (the symbol code L1 is an example of the second symbol code). An example of the label L in FIG. 19 (B) is shown in FIG. 25 (B).

FIG. 20 is a diagram showing an example of the display mode of the icon. As shown in FIG. 20 (A), since the apple label is printed, the display of the apple icon (104P) disappears.

In FIG. 20B, since the operation of the operator is completed, a new product is entered by another operator touching the tag device 20 during the operation of the operator, and based on this entry, a new product is entered. It shows how the product icon is displayed. The apple icon is displayed again because new apples, lemons, and oranges have been entered. In addition, the orange icon 104Q is newly displayed.

A counter value of 104V indicating a numerical value of 2 is displayed on the lemon icon. It can be seen that two operators are planning to purchase lemons. When the counter value is 1, the display of the counter value may be omitted as shown in FIG. 20 (B). As described above, for the icon of the product having the counter value of 2 or more, the value obtained by decrementing the counter value is displayed when the operation of the operator is completed, and the display of the icon is not deleted.

As an example of the trigger for transitioning from the screen of FIG. 20 (A) to the screen of FIG. 20 (B), the operation completion button 104Z is pressed when a predetermined time has elapsed or when a new product is placed. Sometimes, and so on. The operation completion button 104Z may be displayed on another screen. Alternatively, the operation completion button may be displayed on all screens other than the initial screen shown in FIG.
Before displaying the screen of FIG. 20 (B), the initial screen 104b of FIG. 9 may be displayed, and when the operator places the product, FIG. 20 (B) may be displayed.

For example, if the product tag devices corresponding to the products A, B, and C are touched by the operation start time T1 of the first operator, the icons corresponding to the products A, B, and C are displayed. When the weighing device weighs the product A and prints the label, it is completed and the screen is switched. After the operation start time T1 of the first operator, the icons of the products D, E, and F corresponding to the product tag device touched by the operator are also displayed, that is, the products B, C, D, E, The F icon may be displayed.

The display mode of the icons of the products D, E, and F may be different from the display modes of the products A, B, and C, or may be the same display mode. When the display mode is different, for example, when a predetermined time has elapsed from the operation start time T1, or when the operation completion button (FIGS. 20, 104Z) is pressed by the operator, the products B, C, The D, E, and F icons may be displayed in the same manner.

<Embodiment 2>

If the product tag devices corresponding to the products A, B, and C are touched by the operation start time T2 of the first operator, for example, all the weighing and printing of the products A, B, and C are completed. Unless the situation is such that the operation completion button (FIG. 20, 104Z) is pressed by the operator, or the predetermined time has elapsed from the operation start time T2, the first operator The icons of the products D, E, and F corresponding to the product tag device touched by the operator after the operation start time T2 may not be displayed, or the display modes may be displayed differently.

<Modification example 1>

FIG. 21 is a diagram showing an example of the display mode of the icon. The product icon entered before the operator operates the weighing device is displayed in the area A so that the operator can select it.

The icon of the product entered by the operator during the operation is displayed in the area B. Since the icon displayed in the area B is not entered by the operator, it is desirable to display it in gray out, change the color, or prevent selection.

<Modification 2>
FIG. 22 is a diagram showing an example of the display mode of the icon. The product icon entered before the operator operates the weighing device is displayed in the area A so that the operator can select it.

The icon of the product entered by the operator during the operation is displayed in the area B. Since the icon displayed in the area B is not entered by the operator, it is smaller than the icon in the area A, and it is possible to display it in gray out, change the color, or prevent it from being selected. desirable.

<Modification example 3>
FIG. 23 is a diagram showing an example of the display mode of the icon. This is an example in which the size of the icon is changed and displayed at the higher level as the elapsed time from the time when the operator enters the product to the time until the present is longer. The icon displayed at the top is an icon that is likely to be selected by the operator, and the icon displayed small at the bottom is likely to be an icon entered by another operator during the operation of the operator. .. The operator can easily select a product by paying attention to the icon displayed large at the top. In this case, the icon displayed in a small size may not be selected by the operator. Further, for the icon of the entry whose elapsed time is longer than the predetermined time, it is desirable to prohibit the display of the icon and delete the entry as described above. This is because there is a high possibility that the operator mistakenly entered the product.

<Modification example 4>
The time from the first operation by the first operator may be measured by the timer. Then, until a predetermined time (for example, 3 minutes), only the icon of the product pressed by the timing when the first operator starts the operation of the weighing device may be displayed. That is, even if the first operator weighs only one product and completes the label printing, the product selected by the second operator or the like after the timing when the first operator starts operating the product. The icon may not be displayed. However, if the first operator completes the weighing of all the products corresponding to the displayed icons and the printing of the labels by the above-mentioned predetermined time, the second operator selects after the above-mentioned timing. The product icon may be displayed.

<Modification 5>
Further, when the timer reaches a predetermined time, even if the icon of the product selected by the first operator still remains, the product selected by the second operator or later after the above timing. You may want to display the icon of. At this time, the display may be displayed at the moment when the timer reaches the predetermined time, but the display is not changed immediately even when the predetermined time is reached, but the second display is performed after the label issuance process is completed after the predetermined time is reached. The icon of the product selected by the operator or later may be displayed after the timing.

<Embodiment 3>
FIG. 24 is a flowchart showing an embodiment of the operation of the weighing device.
FIG. 24A is a flowchart that monitors information regarding product selection from the tag device and constantly receives the information.
FIG. 24B is a flowchart in which the price of the product is determined from the measured value of the placed product and the touched icon, and the label is issued.

In FIG. 24A, it is desirable that step S501 is periodically started, for example, by an interrupt to form a state in which a plurality of tag devices connected to the weighing device are constantly monitored. The processing of steps S501 to S505 may always be operated by interrupt processing regardless of the mode.

In step 503, when the operator touches the tag device, the PLU data (product identification information) sent from the tag device is received. Then, the process proceeds to step S505.
In step S505, the icon to be displayed corresponding to the received PLU data is specified.
Although the process is completed, it is desirable that the above process be repeated.
