Description

[Technical field]

[0001] The present invention relates to a display control device, a weighing device, a weighing system, and a control program. [Background technology]

[0002] Conventionally, there is known a weighing device that can handle an input value as the weight of an item instead of using a scale when measuring the weight of an item. For example, Patent Document 1 discloses a weighing device that inputs the weight of an item without measuring the weight of a material that has already been measured on a weighing plate.

[0003] [Patent Document 1] JP 2006-308298 A Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, an identifier for identifying whether the weight of an item is a value measured using a scale or a value input by numerical input is recorded as a work history together with the weight of the item, container, etc. Meanwhile, in weighing work, inputting the weight of an item, container, etc. by numerical input is often an irregular response. Therefore, in order to prevent erroneous operation of a weighing device and weighing errors, it is common to make the operation of allowing inputting the weight of an item, container, etc. by numerical input more complicated than the operation of weighing an item, container, etc. using a scale.

[0005] Therefore, in Patent Document 1, when changing the weight of an item, container, etc., the user needs to determine whether the weight value to be changed is a value measured using a scale or a value input by the user in order to prevent unnecessary number input operations. In other words, in Patent Document 1, a process of referring to the work history is required for the user to determine whether the weight value of the item, container, etc. to be changed is a value measured using a scale or a value input by the user in the weighing operation. Therefore, the process for preventing unnecessary number input operations complicates the weighing operation, which becomes a factor in reducing productivity.

[0014] <<1. Overview of the embodiment>> First, an outline of the embodiment will be described.

[0015] (1)Technical issues Conventionally, there is known a weighing device that can handle an input value as the weight of an item instead of using a scale when measuring the weight of an item. For example, a weighing device that inputs the weight of an item without measuring the weight of a measured material on a weighing plate is known.

[0016] In the example device, an identifier for identifying whether the weight of an item is a value measured using a scale or a value input by numerical input is recorded as a work history together with the weight of the item, container, etc. Meanwhile, in weighing work, inputting the weight of an item, container, etc. by numerical input is often an irregular response. Therefore, in order to prevent erroneous operation of the weighing device and weighing errors, it is common to make the operation of allowing inputting the weight of an item, container, etc. by numerical input more complicated than the operation of weighing the item, container, etc. using a scale.

[0017] Therefore, when changing the weight of an item, container, etc., the user must determine whether the weight value to be changed is a value measured using a scale or a value that has been input as a quantity in order to prevent unnecessary input operations of the quantity. In other words, the user must refer to the work history to determine whether the weight value of the item, container, etc. to be changed is a value measured using a scale or a value that has been input as a quantity. Therefore, the process to prevent unnecessary input operations of the quantity makes the weighing work more complicated, which becomes a factor in reducing productivity.

[0018] The present embodiment aims to improve the productivity of the weighing work.

[0019] (2) Example of operation In an embodiment of the present invention, for example, the weight of the object to be weighed displayed on the display unit is displayed in different display modes depending on whether the value is measured using a scale or a value input by entering a number. This makes it easier to determine whether the weight value to be changed is a value measured using a scale or a value input by entering a number, thereby improving the productivity of weighing work.

[0020] The above-mentioned technical features are a specific example of an embodiment of the present invention, and it goes without saying that the embodiment of the present invention is not limited to the above-mentioned technical features.

[0021] <<2. First embodiment>> The first embodiment will be described with reference to Figures 1 to 18. In the following, a weighing device used in a food store or a general household kitchen will be mainly described as an example. Note that the configuration of this embodiment can also be applied to weighing devices used in food factories, farms, post offices, etc., other than stores and kitchens.

[0022] <2.1. Configuration of the measuring device 1> First, a weighing device 1 according to the first embodiment will be described. Fig. 1 is an external perspective view of the weighing device 1 according to the first embodiment. The weighing device 1 is configured to be able to measure the weight of an object to be weighed by placing the object on a weighing plate 55 and weighing it. Note that the weighing device 1 can also weigh the object to be weighed after placing a container on the weighing plate 55 and subtracting the tare weight.

[0023] As shown in FIG. 1, the weighing device 1 has a main body 11, a weighing dish 55 on which the weighing object is placed, a weighing unit 91, an operation panel 65, and a level 56. The main body 11 has a housing made of resin or metal, and the weighing dish 55 is disposed on the upper surface of the main body 11. The operation panel 65 is a touch panel in which the display unit 50 and the operation unit 60 (see FIG. 2) are integrally formed, and is operated by a user of the weighing device 1. The operation panel 65 also displays the weight of the weighing object weighed by the weighing unit 91 and the weight of the weighing object whose number is input. As shown in FIG. 1, the operation panel 65 is provided on the front side of the main body 11. The level 56 is disposed on the upper surface side of the main body 11, and is used by the user to visually check whether the weighing device 1 is disposed so that the weighing dish 55 is horizontal. The weighing unit 91 is built into the main body 11 below the weighing dish 55, as indicated by the dotted line in FIG. 1.

[0024] <2.1.1. Hardware configuration of the weighing device 1> Next, the hardware configuration of the weighing device 1 will be described with reference to Fig. 2. Fig. 2 is a functional block diagram showing the hardware configuration of the weighing device 1. The weighing device 1 includes a CPU (Central Processing Unit) 10, a RAM (Random Access Memory) 20, a ROM (Read Only Memory) 30, a storage medium 40, and an interface (I / F) 70, which are connected via a bus 80. In addition, a display unit 50 and an operation unit 60 are connected to the I / F 70.

[0025] The CPU 10 is a calculation means and controls the operation of the entire weighing device 1. The RAM 20 is a volatile storage medium capable of reading and writing information at high speed, and is used as a working area when the CPU 10 processes information. The ROM 30 is a read-only non-volatile storage medium in which programs such as firmware are stored. The storage medium 40 is a non-volatile storage medium such as a HDD (Hard Disk Drive) in which information can be read and written, and in which an OS (Operating System), various control programs, application programs, etc. are stored.

[0026] The I / F 70 connects and controls the bus 80 with various hardware, networks, etc. The display unit 50 is a display such as an LCD (Liquid Crystal Display), and is a visual user interface that allows the user to check the status of the weighing device 1. The operation unit 60 is a user interface such as a keyboard or mouse that allows the user to input information to the weighing device 1. In this embodiment, the display unit 50 and the operation unit 60 are configured as an integrally formed operation panel 65, which can display weight information regarding the weight of the object to be weighed.

[0027] The weighing unit 91 is a weight detection module such as a load cell that has a strain gauge or a piezoelectric element that deforms when subjected to the weight of the object to be weighed placed on the weighing pan 55 (see Figure 1), and outputs a change in resistance value corresponding to the amount of deformation as a voltage value.

[0028] An A / D converter 90 that converts an analog signal from the weighing unit 91 into a digital signal is connected to the bus 80. The voltage value output from the weighing unit 91 is converted into a pulse signal in the A / D converter 90 and input to the CPU 10 via the bus 80. The CPU 10 calculates the weight of the object to be weighed based on the pulse signal input via the bus 80. In the following description, information related to weighing by the weighing unit 91, such as the pulse signal into which the voltage value output from the weighing unit 91 is converted by the A / D converter 90, is referred to as "weighing information."

[0029] In such a hardware configuration, the software control unit of the weighing device 1 is configured by the CPU 10 performing calculations according to a program stored in the ROM 30 or a program loaded from the storage medium 40 to the RAM 20. The software control unit configured in this way is combined with hardware to configure a controller 100 (see FIG. 3) for realizing the functions of the weighing device 1 according to this embodiment.

[0030] <2.1.2. Configuration of the controller 100 of the weighing device 1> Next, the functional configuration of the weighing device 1 will be described with reference to Fig. 3. Fig. 3 is a functional block diagram showing the functional configuration of the weighing device 1. The weighing device 1 has a controller 100 that controls the overall operation of the weighing device 1. The controller 100 includes a communication processing unit 110, a main control unit 120, and a storage unit 130.

[0031] The communication processing unit 110 controls the exchange of information with the controller 100 via the I / F 50. For example, the communication processing unit 110 receives information on a user's operation on a soft key displayed on the operation panel 65 (hereinafter referred to as "operation information") from the operation panel 65 and inputs it to the main control unit 120. The communication processing unit 110 also receives information for controlling a screen displayed on the operation panel 65 (hereinafter referred to as "screen information") from the main control unit 120 and transmits it to the operation panel 65 via the I / F 50.

[0032] Furthermore, the communication processing unit 110 receives the measurement information via the I / F 50. As described above, the measurement information is information including a pulse signal into which the voltage value output from the measurement unit 91 is converted, and the like.

[0033] The main control unit 120 includes a measurement processing unit 121, a process execution switching unit 122, and a display processing unit 123, and controls the entire controller 100.

[0034] The weighing processing unit 121 performs a calculation to subtract the tare weight from the weight measured by the weighing unit 91 based on the weighing information, and passes the calculation result to the display processing unit 123. The tare weight in the weighing device 1 can be a value preset in the weighing device 1 or a value obtained by measuring the weight of a tare placed on the weighing pan 55. The weighing processing unit 121 also performs a calculation based on an input value of the weight of the object to be weighed.

[0035] The process execution switching unit 122 switches the display mode of the weight information displayed on the operation panel 65. Examples of the display mode of the weight information in the weighing device 1 include a mode (hereinafter, "first mode") in which information (hereinafter, "first information") including the weight (measured value) measured by the weighing unit 91 (see FIG. 2) is displayed on the operation panel 65 in a first manner, and a second mode (hereinafter, "second mode") in which information (hereinafter, "second information") including the weight (input value) inputted as a quantity from the operation unit 60 (e.g., the operation panel 65, etc.) is displayed on the operation panel 65 in a second manner different from the first manner. Specifically, the process execution switching unit 122 switches between the first mode and the second mode based on the operation information. The specific operation of the process execution switching unit 122 and the user's operation on the operation panel 65 will be described in detail later.

[0036] The display processing unit 123 generates screen information based on the information received from the weighing processing unit 121 and the process execution switching unit 122, and transmits it to the operation panel 65 via the communication processing unit 110. When causing the operation panel 65 to display the weight of the object to be weighed, the display processing unit 123 transmits the weight information together with the screen information. In other words, the screen displayed on the operation panel 65 (display unit 50) is controlled by the display processing unit 123.

[0037] The memory unit 130 includes a combination information memory unit 131 and an input value memory unit 132, and stores various information upon receiving commands from the main control unit 120. The combination information memory unit 131 stores a combination data table 700 (see FIG. 5) described later. The input value memory unit 132 stores a value input as a quantity via the operation panel 65 in the second mode. The information stored in the memory unit 130 may include a value preset as a tare weight and a value of the weight of the object to be weighed weighed by the weighing unit 91.

[0038] With such a configuration, the weighing device 1 of this embodiment can operate in a first mode in which first information including a measurement value of the weight of the objects to be weighed measured by the weighing unit 91 is displayed in a first manner on the operation panel 65, and in a second mode in which second information including an input value of the weight of the objects to be weighed inputted as a quantity from the operation unit 60 such as the operation panel 65 is displayed in a second manner. In other words, the weighing device 1 also functions as a display control device in this embodiment.

[0039] <2.2. Configuration of the weighing screen 500 displayed on the weighing device 1> Next, the configuration of the weighing screen 500 displayed on the operation panel 65 of the weighing device 1 will be described with reference to Fig. 4. Fig. 4 is a diagram showing an example of the configuration of the weighing screen 500 displayed on the operation panel 65. The weighing screen 500 includes a first display section 510, a second display section 520, a third display section 530, and a fourth display section 570.

[0040] First display section 510 includes a weight display area 514 in which the weight of the object to be weighed is displayed, and a tare weight display area 512 in which the tare weight set when the object to be weighed is displayed. When weighing is performed with a tare placed on weighing pan 55, the weight of the tare weighed by weighing section 91 is displayed in tare weight display area 512. When a preset value as the tare weight is stored in memory section 130, the preset value as the tare weight may be displayed in tare weight display area 512.

[0041] The second display section 520 is an area that displays information (hereinafter, referred to as "difference information") on the difference between a preset weight value for each weighing object and a weighing value or input value of the weighing object in the blending data table 700. As the difference information, for example, an indicator 522 (see FIG. 9) described later is displayed on the second display section 520. Note that on the weighing screen 500, the second display section 520 is displayed in an area that does not overlap with the first display section 510.

[0042] Also, the second display section 520 can display a mode switching area 524 (see FIG. 10) that is operated by the user to switch between displaying the weight of the object to be weighed displayed on the weighing screen 500 in the first mode or the second mode. Furthermore, based on an operation on the mode switching area 524, the second display section 520 can display number input keys 550 (see FIG. 11) including a plurality of soft keys that allow number input. The configuration for changing the display on the second display section 520 will be described in detail later.

[0043] The third display section 530 includes a plurality of soft keys operated by the user to switch the display of the first display section 510 and the second display section 520. Specifically, the third display section 530 includes a mode key 531 for displaying the mode switching area 524, and a number pad key 532. The third display section 530 also includes a tare key 533 operated when weighing a tare, and a reset key 534 for resetting the value displayed in the weight display area 514. The soft keys included in the third display section 530 are always displayed on the weighing screen 500. Note that, on the weighing screen 500, the third display section 530 is displayed in an area that does not overlap with the first display section 510 and the second display section 520.

[0044] The fourth display section 570 is an area where information stored in the blending data table 700 is displayed. In the weighing screen 500, the fourth display section 570 is displayed in an area that does not overlap with the first display section 510, the second display section 520, and the third display section 530. Here, the information displayed on the fourth display section 570 will be described together with the configuration of the blending data table 700 in FIG.

[0045] The fourth display section 570 includes an ingredient selection area 571 for selecting an ingredient to be weighed, and an ingredient information display area 572 for displaying information (hereinafter referred to as "ingredient information") stored in association with the ingredient in the blending data table 700.

[0059] The information in the special information 708 includes, for example, information on the handling of ingredients. As an example shown in FIG. 5, in the case of an ingredient (mixed flour) with an ingredient ID 703 of "0002", it is shown that by using 10 cases of mixed flour with an ingredient code of "12346···" and a lot number of "4678···", the mixed flour can be weighed at "6000g". That is, in such a case, the mixed flour is prepared according to the information stored in the special information 708, and the weight of the prepared mixed flour, "6000g", is input from the quantity input key 550 (see FIG. 11). In this way, in this embodiment, the weight of the object to be weighed can be input as a quantity. Therefore, for example, the process of weighing weak flour and strong flour separately can be omitted so that the ratio of weak flour and strong flour can be mixed at a predetermined ratio. In addition, even if the handling of an ingredient such as wheat flour is complicated because it flies up when weighed, the target weight can be easily measured. In addition, for example, by operating the operation panel 65, it is also possible to cause the weighing device 1 to display the weight of the object to be weighed, which has been previously weighed by another weighing device.

[0060] In FIG. 5, the ingredient ID 703 of "0006" is stored as "240mL" in the special information 708. The brandy ID 703 of "0006" is alcohol. In this way, there are cases where measuring the volume can better accommodate changes in the state of the object to be measured than measuring the weight. In this embodiment, the special information 708 may be stored with information on the volume of the object to be measured, which corresponds to the blending instruction amount stored in the instruction amount 705. In this case, the user measures out "240mL" of brandy according to the information stored in the special information 708, and inputs "280g", which is the weight of the measured brandy, from the quantity input key 550 (see FIG. 11). In this way, in this embodiment, it is possible to perform measurement in response to changes in the state of the object to be measured, such as when the object to be measured is liquid or volatile.

[0061] The special information 708 may also include information indicating that a weighing operation cannot be performed with the value input from the quantity input key 550 as the weighing object. For example, the special information 708 may store information such that when the material and amount can be measured by preparing multiple bags of pre-weighed items (500 g, 1 kg, etc.) and the target weight can be measured (for example, when preparing five packs of 500 g flour and measuring out 2500 g), the quantity can be input from the quantity input key 550, and when this is not possible (when measuring out 600 g of eggs), the quantity cannot be input from the quantity input key 550.

[0062] Even if information that prohibits input of a quantity from the quantity input keys 550 is stored as the special information 708, the quantity may be made inputtable in the following cases. For example, in cases where the weighing device 1 is not directly used for commercial transactions or where a weight measured by a weighing device other than the weighing device 1 is used by inputting a quantity, the quantity may be made inputtable from the quantity input keys 550. In cases where the weight stored in the indicated amount 705 falls outside the measurement compensation range of the weighing unit 91 based on the Measurement Act, information may be stored as the special information 708 that allows the object to be weighed to be weighed only by inputting a quantity from the quantity input keys 550.

[0063] In this manner, in the weighing device 1 of this embodiment, the weighing operation can be performed by using the value measured by the weighing unit 91 (measured value) or the value inputted as a number using the number input keys 550 (input value) as the weight of the object to be weighed.

[0064] <2.3. Overview of procedure for displaying the weight of the object to be weighed in the weighing device 1> Next, an overview of the procedure for displaying the weight of the object to be weighed in the weighing device 1 will be described with reference to Fig. 6 to Fig. 16. Fig. 6 is a flowchart showing the procedure for displaying the weight of the object to be weighed on the operation panel 65 in the weighing device 1. Fig. 7 is a flowchart showing the procedure for editing the weight of the object to be weighed displayed on the operation panel 65. Fig. 7 is a flowchart showing the procedure for re-displaying the weight of the object to be weighed displayed on the operation panel 65. Figs. 9 to 17 are diagrams showing an example of a weighing screen 500 displayed on the operation panel 65 of the first embodiment.

[0065] A weighing operation using the weighing device 1 is started by the main control unit 120 when the weighing device 1 is powered on and the operation panel 65 is operated or an object to be weighed is placed on the weighing pan 55 as a trigger. In order to indicate that the weighing operation in the weighing device 1 is ready to start, the display processing unit 123 may display a weighing screen 500 as shown in FIG. 4 on the operation panel 65. In this embodiment, the explanation will be given on the assumption that the weighing operation in the weighing device 1 is ready to start when the weighing screen 500 is displayed on the operation panel 65 and the ingredient (mixed flour) with the ingredient ID 703 of "0002" is selected. In addition, in the weighing device 1, the display mode of the weight information is set to "first mode" at the start of the weighing operation.

[0066] At the start of this flow, the display mode of the weight information is the first mode, so the display processing unit 123 displays the indicator 522 and the confirmation key 523 on the second display unit 520. As described above, the indicator 522 corresponds to difference information that displays information on the difference between the weight setting value set in advance for each weighing object and the measured value or input value of the weight of the weighing object. Here, since "0002" is selected as the ingredient ID 703, at the start of this flow, the difference information is displayed based on the information of the instruction amount 705 associated with the ingredient ID 703 of "0002". That is, FIG. 9 shows that "6000g" is required to reach the weight indicated by the instruction amount 705. At this time, if the confirmation key 523 is operated without performing weighing, the display processing unit 123 may display a dialogue indicating that the mixed flour has not been weighed on the second display unit 520.

[0067] 6, in step S11, the process execution switching unit 122 receives operation information via the communication processing unit 110 and determines whether or not the number entry execution key 525 (see FIG. 10) included in the mode switching area 524 has been operated.

[0068] As shown in Fig. 9, at the start of this flow, the display mode of the weight information is the first mode, and therefore the mode switching area 524 is not displayed on the second display unit 520. When inputting the weight of the object to be weighed by entering a quantity, the user operates the mode key 531 of the third display unit 530 on the weighing screen 500 of Fig. 9. Then, when the mode key 531 is operated, the display of the weighing screen 500 transitions from Fig. 9 to Fig. 10, and the mode switching area 524 is displayed on the second display unit 520.

[0069] 10, mode switching area 524 includes a number entry execution key 525 for switching the weight information display mode from the first mode to the second mode, and a number entry cancellation key 526 for switching the weight information display mode from the second mode to the first mode. When the process execution switching unit 122 determines in step S11 that number entry execution key 525 has been operated (S11 / Y), it switches the weight information display mode from the first mode to the second mode and proceeds to step S12.

[0070] When it is determined that the quantity input execution key 525 has been operated (S11 / Y), the display processing unit 123 in step S12 causes the second display unit 520 to display the quantity input key 550. In step S12, the display of the measurement screen 500 transitions from that shown in FIG. 10 to that shown in FIG.

[0071] In step S13, the user operates the quantity input keys 550 displayed on the second display unit 520 to input the weight of the "mixed flour". The display processing unit 123 specifies the value inputted in step S13 based on the operation information. In FIG. 12, for the sake of explanation, it is assumed that the keys 551, 552, and 553 included in the quantity input keys 550 are operated consecutively in step S13. At this time, the display processing unit 123 displays "5000g" in the display area 554, which corresponds to the consecutive operations of the keys 551, 552, and 553. Then, when the confirmation key 555 is operated with "5000g" displayed in the display area 554, the display processing unit 123 displays the value ("5000g") displayed in the display area 554 in the weight display area 514 in step S14. Furthermore, in step S14, the display processing unit 123 causes the value displayed in the display area 554 ("5000g") to be underlined and displayed in the weight display area 514.

[0072] The display mode when the values ​​displayed on the first display unit 510 are underlined corresponds to the second mode of this embodiment (see FIG. 13). On the other hand, the display mode when the values ​​displayed on the first display unit 510 are not underlined corresponds to the first mode of this embodiment (see FIG. 16). In this manner, in this embodiment, the values ​​displayed on the first display unit 510 are emphasized in the second mode more than in the first mode by underlining the values. Therefore, in the second mode, the user can be given a stronger impression than in the first mode that the displayed value can be touched, for example, as in a hyperlink display that prompts the user to click on a text example.

[0073] In addition to the above, for example, the value may be displayed in white characters in the first mode and in blue characters in the second mode. Furthermore, the value may be constantly lit in the first mode and flashed in the second mode.

[0074] In step S14, the display processing unit 123 underlines the value ("5000g") displayed in the display area 554 and displays it in the weight display area 514, and in step S15 changes the display of the second display unit 520 from the quantity input keys 550 to the difference information. At this time, the display of the weighing screen 500 transitions from that shown in FIG. 12 to that shown in FIG. 13, and the quantity input keys 550 are no longer displayed on the second display unit 520.

[0075] The weight of the "mixed flour" input in step S13 ("5000g") is "1000g" less than the specified amount of "6000g" stored in the blending data table 700. The weighing processing unit 121 performs a calculation based on the input value of the weight of the weighing object input in step S13 and the specified amount stored in the blending data table 700, and transfers the calculation result to the display processing unit 123. The display processing unit 123 displays difference information indicating that the weight of the "mixed flour" input in step S13 ("5000g") is "1000g" less than the specified amount of "6000g" stored in the blending data table 700 on the second display unit 520 (see FIG. 13).

[0076] If the weight of the "mixed flour" input in the quantity in step S13 is ("6000g"), the weighing processing unit 121 passes the calculation result indicating that the input value in step S13 is the same as the specified amount stored in the blending data table 700 to the display processing unit 123. In step S15, the display processing unit 123 causes the second display unit 520 to display information indicating that the weight of the "mixed flour" input in the quantity in step S13 ("6000g") is the same as the specified amount "6000g" stored in the blending data table 700 (see FIG. 15).

[0077] In this manner, in this embodiment, when the weight of the object to be weighed is inputted as a quantity, the quantity input keys 550 are displayed on the second display unit 520. Then, the input value of the weight of the object to be weighed is displayed in the weight display area 514, and the display of the second display unit 520 transitions from the quantity input keys 550 to difference information. This allows the user to visually recognize the difference between the weight of the object to be weighed inputted by the quantity input keys 550 and the indicated amount stored in the blending data table 700.

[0078] The user can determine from the display of the weighing screen 500 in Fig. 13 that the weight of "mixed flour", which is the value input in step S13, is less than the specified amount. Then, when re-inputting the weight of "mixed flour" input in step S13, the user operates the weight display area 514. On the other hand, when continuing the weighing operation using the weight of "mixed flour" input in step S13, the user operates the enter key 523.

[0079] Then, in step S16, the display processing unit 123 judges whether or not an operation has been performed on the weight display area 514. For example, if the confirmation key 523 has been operated, the display processing unit 123 judges that no operation has been performed on the weight display area 514 (S16 / N) and ends this process. On the other hand, for example, if the display processing unit 123 receives first area operation information indicating that a touch operation or the like has been performed on the weight display area 514, the display processing unit 123 judges that an operation has been performed on the weight display area 514 (S16 / Y) and proceeds to the flow of FIG. 7 (FIG. 6, A). The weight display area 514 corresponds to the first area in this embodiment. Note that, when the weight of a container is weighed or the number of containers is input as the object to be weighed, the container weight display area 512 corresponds to the first area in this embodiment. Thus, the first area in this embodiment corresponds to the area of ​​the weighing screen 500 where the value of the weight of the object to be weighed, the number of containers being input, is displayed by operating the confirmation key 523.

[0080] In weighing operations, it is generally irregular to input the weight of an object, a container, etc., by specifying the number of items. Therefore, the operation to input the weight of an object, a container, etc., by specifying the number of items, etc., may be complicated. 2. Description of the Related Art In a conventional device having a mechanical key for inputting a quantity, it is possible to edit the weight of an object to be weighed, for which the quantity has been input, by operating the mechanical key.

[0081] In contrast, in the weighing device 1 of this embodiment, the quantity input keys 550 are displayed on the operation panel 65. Then, when the input value of the weight of the object to be weighed is displayed in the weight display area 514, the display of the second display unit 520 transitions from the quantity input keys 550 to difference information. In this embodiment, by displaying the input value of the weight of the object to be weighed in the second mode, it becomes easier for the user to recognize where on the weighing screen 500 the weight of the object to be weighed for which the quantity has been input is displayed.

[0082] Furthermore, in this embodiment, as described later, when the user operates the weight display area 554 while the input value of the weight of the weighing object is displayed, the number input key 550 is displayed again on the second display unit 520. In this way, the input value of the weight of the weighing object is displayed more emphatically than other character strings displayed on the weighing screen 500, so that the user recognizes that operation on the weight display area 514 is possible. Then, the weight of the weighing object whose number has been input can be edited by using the operation on the weight display area 514 as a trigger, so that the weight of the article, container, etc. whose number has been input can be edited and displayed with a simpler operation. In other words, the second mode is also a display mode of the weight of the weighing object when the weight display area 514 can be used as a trigger key for editing the weight of the weighing object whose number has been input.

[0083] Next, a flow of steps of the display switching process for editing and displaying the weight of the object to be weighed displayed on the operation panel 65 will be described with reference to FIG. 7. When the display processing unit 123 determines that an operation has been performed on the weight display area 514 (S16 / Y), in step S21, the second display unit 520 is caused to display the quantity input key 550 again. At this time, in step S21, the display of the weighing screen 500 transitions from FIG. 13 to FIG. 14, and the quantity input key 550 is displayed on the second display unit 520. As shown in FIG. 14, when the quantity input key 550 is displayed again on the second display unit 520 in step S21, the weight display area 514 is in a state where the value displayed underlined in step S14 is displayed. In the flow of FIG. 7, the input value of the weight of the object to be weighed displayed underlined in the weight display area 514 before the operation on the weight display area 514 corresponds to the first input value in this embodiment.

[0084] Then, in step S22, the user operates the quantity input keys 550 displayed on the second display section 520 to input the weight of the "mixed flour". The display processing section 123 judges the value inputted in step S22 based on the operation information. If the weight of the "mixed flour" inputted in step S22 is ("6000g"), the display processing section 123 displays "6000g" in the display area 554. After the weight value of the weighing object inputted in the quantity input by the quantity input keys 550 is displayed in the weight display area 514, in the flow of FIG. 7, the value inputted in the quantity input by the quantity input keys 550 and displayed in the weight display area 514 in an underlined state corresponds to the second input value of this embodiment. In other words, the second input value corresponds to the value obtained by editing the first input value displayed in the weight display area 514 by operating the quantity input keys 550.

[0085] Then, when the confirmation key 555 is operated with "6000g" displayed in the display area 554, the display processing unit 123 reflects and displays the value ("6000g") displayed in the display area 554 in the weight display area 514 in step S23. In addition to step S23, the display processing unit 123 changes the display of the second display unit 520 from the number entry key 550 to the difference information in step S24. At this time, the display of the weighing screen 500 transitions from FIG. 14 to FIG. 15, and the number entry key 550 is not displayed in the second display unit 520. The second display unit 520 corresponds to the second area in this embodiment. Note that, although an example in which the number entry key 550 is displayed in the entire area of ​​the second display unit 520 is shown in FIG. 13, FIG. 14, and FIG. 15, the number entry key 550 may be displayed in a display layer above the difference information such as the indicator 522. In other words, the number input keys 550 may be displayed on at least a part of the second display section 520 .

[0086] Furthermore, the measurement processing unit 121 transfers to the display processing unit 123 the calculation result indicating that the input value in step S22 is the same as the specified amount stored in the blending data table 700. The display processing unit 123 causes the second display unit 520 to display information indicating that the weight of the "mixed flour" input in step S22 ("6000g") is the same as the specified amount "6000g" stored in the blending data table 700 (see FIG. 15).

[0087] 15, and if the user wishes to use the input value of the weight of the "mixed flour" input in step S22 as the value to be used in the weighing operation, he / she operates the confirmation key 523. On the other hand, if the user wishes to re-input the weight of the "mixed flour" as the quantity, he / she operates the weight display area 514.

[0088] In step S25, the display processing unit 123 determines whether or not an operation has been performed in the weight display area 514. If an operation has been performed in the weight display area 514 (S25 / Y), the process returns to S21. On the other hand, if an operation has not been performed in the weight display area 514 (S25 / N), the process waits in step S26 until the enter key 523 is operated, and if the enter key 523 is operated (S26 / Y), the process ends.

[0089] If the confirmation key 555 is operated without inputting a quantity in step S22 (S22 / N), the display processing unit 123 changes the display in the second display unit 520 from the quantity input keys 550 to the difference information while maintaining the display in the weight display area 514 at "5000g". Then, the display processing unit 123 waits until the confirmation key 523 is operated in step S27, and ends this flow when the confirmation key 523 is operated (S27 / Y).

[0090] Returning to the flowchart of Fig. 6, the procedure from step S17 onwards will be described. In step S11, when it is determined that the quantity input execution key 525 has not been operated (S11 / N), the measurement processing unit 121 waits until the weighing unit 91 performs weighing. Then, in step S17, the measurement processing unit 121 acquires the measured value of the weight of the object to be weighed by the weighing unit 91, performs calculation, and passes the calculation result to the display processing unit 123. In this case, since the display mode of the weight information is the first mode, in step S18, the display processing unit 123 displays the calculation result received from the measurement processing unit 121 in the weight display area 514 in the first mode, and ends this flow.

[0091] In this way, in this embodiment, the weight of the object to be weighed can be input as a number. Therefore, for example, when "6000g" of "mixed flour" is to be measured, the weight of the "mixed flour" can be input as a number to obtain a mixture of weak flour and strong flour in a predetermined ratio in an amount corresponding to the target amount. In addition, since the display mode of the input value is different from the display mode of the measured weight of the object to be weighed, the user can easily determine whether the weight displayed on the operation panel 65 is the input value or the measured value. Therefore, unlike conventional weighing instruments, there is no need to check the work history, and the productivity of the weighing work can be improved.

[0092] In this embodiment, the display mode of the weight information can be switched between the first mode and the second mode by operating the quantity input execution key 525 or the quantity input cancellation key 526. Therefore, the user can check with a simpler operation whether the weight displayed on the operation panel 65 is the quantity input value or the measured value.

[0093] In addition, in this embodiment, when the quantity input execution key 525 is operated, the quantity input key 550 is displayed so as to overlap with the indicator 522 displayed on the weighing screen 500. Therefore, the display area of ​​the operation panel 65 can be effectively utilized.

[0094] Furthermore, in this embodiment, the weight display area 514 in which the value is displayed in the second mode is used as a trigger key for editing the weight of the object to be weighed whose quantity has been input, so that the weight of the object to be weighed whose quantity has been input can be edited again with a simpler operation, and the re-edited weight can be used in the weighing work. Therefore, the productivity of the weighing work can be improved compared to conventional weighing devices.

[0095] <2.4. Modification 1: Overview of Procedure for Redisplaying the Weight of an Object to be Weighed in the Weighing Device 1> Next, a procedure flow when the weight of the object to be weighed is re-displayed on the operation panel 65 will be described with reference to Fig. 8, Fig. 9, and Fig. 12. Fig. 8 is a flowchart showing a procedure flow when the weight of the object to be weighed is re-displayed on the operation panel 65. In this modification, the description will be given on the assumption that the weighing screen 500 is displayed on the operation panel 65 in this embodiment, and an ingredient (mixed flour) with an ingredient ID 703 of "0002" is selected.

[0096] 8 is triggered by, for example, displaying the number entry keys 550 on the second display unit 520 in step S31 by the display processing unit 123 in the same manner as in step S12, step S21, etc. At this time, the measurement screen 500 is in a state in which the number entry keys 550 are displayed on the second display unit 520 (see FIG. 12).

[0097] In step S32, the user operates the quantity input keys 550 displayed on the second display unit 520 to input the weight of the "mixed flour." If the weight of the "mixed flour" inputted in step S32 is ("5000g"), the input value storage unit 132 stores "5000g" as the input value from the quantity input keys 550 in step S33.

[0098] Next, in step S34, the display processing unit 123 determines whether or not the input of the number is completed using the number input keys 550. For example, when the confirmation key 555 included in the number input keys 550 is operated, the display processing unit 123 determines that the input of the number is completed using the number input keys 550, and proceeds to step S14 in FIG.

[0099] On the other hand, when the confirmation key 555 included in the number input keys 550 is not operated, the display processing unit 123 determines that the number input from the number input keys 550 is not completed (S34 / N), and proceeds to step S35. For the sake of explanation, it is assumed in step S35 that the number pad keys 532 included in the third display unit 530 are operated.

[0100] For example, when the number pad keys 532 are operated while the number input keys 550 are displayed on the second display unit 520, the display processing unit 123 performs a first switching process of making the number input keys 550 displayed on the second display unit 520 invisible. On the other hand, when the number pad keys 532 are operated while the number input keys 550 are not displayed on the second display unit 520, the display processing unit 123 performs a second switching process of making the number input keys 550 displayed on the second display unit 520 visible.

[0101] When the display processing unit 123 receives switching operation information indicating that the number pad keys 532 have been operated in step S35, it executes a first switching process to put the digit input keys 550 in a non-display state.

[0102] Then, when the display processing unit 123 receives switching operation information indicating that the number pad keys 532 have been operated in step S36 after executing the first switching process, it executes a second switching process in step S37 to display the number input keys 550. When displaying the number input keys 550 in S37, it displays the input value stored in step S33 in the display area 554 and returns to step S34. On the other hand, if switching operation information indicating that the number pad keys 532 have been operated is not received in step S36, the main control unit 120 ends this flow.

[0103] When switching between the display state and non-display state of the number-specifying input keys 550 in this modified example, screen information for displaying either the number-specifying input keys 550 or the difference information on the second display unit 520 is transmitted to the operation panel 65. When switching the display on the second display unit 520 from the difference information to the number-specifying input keys 550, the input value stored in the input value storage unit 132 is referenced.

[0104] In addition to the above, for example, image information for adjusting the display coordinates of the numeral input keys 550 with respect to the coordinates of the display area of ​​the second display unit 520 may be transmitted to the operation panel 65. Also, screen information for switching the display layer of the second display unit 520 to the layer of the numeral input keys 550 or the layer of difference information may be transmitted to the operation panel 65.

[0105] In this manner, in this modified example, if there is an input value that was input as a number before the number input keys 550 became hidden, it can be displayed by the second switching process together with the number input keys 550. Therefore, when the weighing operation is temporarily interrupted and then resumed, it is possible to continue using the value that was input as a number before the interruption, thereby improving the productivity of the weighing operation.

[0106] <2.5. Modification 2: Example of operation for changing input value displayed in display area 554> 11 and 17, an operation example in which the input value displayed in the display area 554 is changed depending on whether the weight display area 514 has been operated will be described. In this modification, after the process execution switching unit 122 switches from the first mode to the second mode, the manner in which the input value is displayed in the display area 554 is changed depending on whether the weight display area 514 has been operated.

[0107] When the quantity input execution key 525 is operated to switch to the second mode, and a quantity input is performed using the quantity input keys 550 before the weight display area 514 is operated, the display processing unit 123 displays the input value in the display area 554 in the third mode. Specifically, the display processing unit 123 displays the input value as is in the display area 554 without indicating unit information, etc. The display mode when the input value is displayed as is in the display area 554 without indicating unit information, etc. corresponds to the third mode of this embodiment. In other words, the third mode is a display mode in which information related to the input value, such as unit information and information on significant digits of the input value, is not displayed in the display area 554.

[0108] On the other hand, when the number input execution key 525 is operated to switch to the second mode, and then the weight display area 514 is operated and a number input is performed using the number input key 550, the display processing unit 123 displays the input value in the display area 554 in the fourth mode. Specifically, the display processing unit 123 displays the input value together with unit information and the like (in FIG. 11, "g: grams") in the display area 554 (see FIG. 11). The display mode when the input value is displayed in the display area 554 together with the unit information and the like corresponds to the fourth mode of this embodiment. In other words, the third mode is a display mode in which the input value is displayed in the display area 554 together with information on the input value, such as unit information and information on significant digits of the input value.

[0109] In addition, after the process execution switching unit 122 switches from the first mode to the second mode, the manner in which the input value is displayed in the display area 554 may be changed depending on whether or not the tare weight display area 512 is operated.

[0110] This allows the user to accurately determine which value is being input when performing a weighing operation with the weighing device 1. This improves the user experience during weighing operations.

[0111] <2.6. Modification 3: Example of operation for displaying confirmation screen 560> Next, an example of an operation for displaying a confirmation screen 560 on the operation panel 65 will be described with reference to Fig. 18. In this modification, when the quantity input execution key 525 is operated while weighing is being performed in the weighing unit 91, the display processing unit 123 displays a confirmation screen 560 as shown in Fig. 18 on the operation panel 65. As shown in Fig. 18, the confirmation screen 560 includes a confirmation display unit 561, an OK key 562, and a cancel key 563. Note that, although Fig. 18 shows an example in which the confirmation screen 560 is displayed on the second display unit 520, the confirmation screen 560 may also be displayed instead of the weighing screen 500.

[0112] When weighing is being performed in the weighing unit 91, it is considered that the weighing value is already displayed in the weight display area 541. In such a situation, when the quantity entry execution key 525 is operated, in this embodiment, the display processing unit 123 displays a confirmation screen 560 on the operation panel 65 to confirm whether or not the display mode of the weight information is to be executed in the second mode. Then, when confirmation operation information is received indicating that an operation to confirm that the display mode of the weight information is to be executed in the second mode has been performed on the confirmation screen 560, such as the operation of the OK key 562, the display processing unit 123 executes the second mode. In this case, the weighing value displayed in the weight display area 541 at the timing when the quantity entry execution key 525 is operated is reset.

[0113] 18, the display on the confirmation display unit 561 may be text information such as "Quantity cannot be entered" or "Please remove the object to be weighed from the weighing plate." When the text information "Quantity cannot be entered" is displayed on the confirmation display unit 561, the transition from the first mode to the second mode may be prohibited. When the text information "Please remove the object to be weighed from the weighing plate" is displayed on the confirmation display unit 561, the transition from the first mode to the second mode may be prohibited until the object to be weighed is removed from the weighing plate 95.

[0114] In this manner, in this modified example, when the weighing unit 91 is about to switch from the first mode to the second mode while weighing, the user is made to perform a confirmation operation, so that the weighing value and the input value are not displayed simultaneously on the operation panel 65. This prevents the user from performing a step that is unnecessary for the weighing operation, for example, when the weighing unit 91 is weighing the weighing object and the user attempts to input the weight of the weighing object by mistake, thereby further improving the productivity of the weighing operation. It is also possible to provide a weighing device 1 that complies with the standards set forth in the Measurement Act.

[0115] <2.7. Other Modifications> As described above, in this embodiment, the display mode of the weight information can be switched from the first mode to the second mode by operating the quantity input execution key 525 displayed on the operation panel 65. Note that, in addition to this, the display mode of the weight information may be switched from the first mode to the second mode by, for example, a toggle switch or the like mounted on the housing of the main body 11 of the weighing device 1.

[0116] Furthermore, in addition to the above, as the display mode of the weight information in the weighing device 1, for example, a screen having a hue and saturation different from the screen of the first mode may be displayed on the operation panel 65 as a screen of the second mode. In this case, when displaying the first information on the operation panel 65, the display processing unit 123 adjusts the hue and saturation so that the screen displayed on the operation panel 65 has a greenish color. Also, when displaying the second information, the display processing unit 123 adjusts the hue and saturation so that the screen displayed on the operation panel 65 has a reddish color. In this way, the hue and saturation of the screen itself displayed on the operation panel 65 may be adjusted as the first mode and the second mode.

[0117] Furthermore, the display processing unit 123 may make the hue and saturation of the first display unit 510 different between the first mode and the second mode. In addition to this, the display processing unit 123 may change the screen displayed on the operation panel 65 so that characters are displayed as outline characters in the first mode and outline characters in which the outlined parts in the first mode are colored in the second mode.

[0118] <<3. Second embodiment>> Next, a second embodiment will be described with reference to Figures 19 to 21. The above-mentioned first embodiment has been described as a configuration in which a controller 100 as a display control device is integrally implemented in a weighing device 1. In contrast, the second embodiment will be described as a configuration of a weighing system 1000 having a display control device 1A implemented with a controller 200, and a weighing instrument 2A implemented with a weighing unit 93 and an A / D converter 92.

[0119] <3.1. Configuration of the weighing system 1000> First, an operation form of the weighing system 1000 according to this embodiment will be described with reference to Fig. 19. Fig. 19 is a diagram showing an example of the configuration of the weighing system 1000 according to this embodiment. As shown in Fig. 19, the weighing system 1000 includes a display control device 1A to which a display as a display unit 52 and an input terminal as an operation unit 62 are communicably connected, and a weighing instrument 2A capable of communicating with the display control device 1A.

[0120] The display unit 52, the operation unit 62, and the display control device 1A may be an integrated terminal, such as a tablet terminal.

[0121] <3.1.1. Relationship with the first embodiment> Next, a hardware configuration and a functional configuration of the weighing system 1000 will be described with reference to Fig. 20 and Fig. 21. Fig. 20 is a block diagram showing a hardware configuration of the weighing system 1000. Fig. 21 is a functional block diagram showing a functional configuration of a display control device 1A included in the weighing system 1000.

[0122] As an example, the CPU 12, RAM 22, ROM 32, storage medium 42, interface 72, and bus 82 constituting the display control device 1A according to the second embodiment correspond to the CPU 10, RAM 20, ROM 30, storage medium 40, interface 70, and bus 80 of the weighing device 1 according to the first embodiment. The A / D converter 92 and weighing unit 93 constituting the weighing instrument 2A according to the second embodiment correspond to the A / D converter 90 and weighing unit 91 of the weighing device 1 according to the first embodiment. The display unit 52 and operation unit 62 according to the second embodiment correspond to the display unit 50 and operation unit 60 of the first embodiment.

[0123] As shown in FIG. 21, the display control device 1A has a controller 200 that controls the operation of the entire weighing system 1000. The controller 200 includes a communication processing unit 210, a main control unit 220, and a storage unit 230. The communication processing unit 210, the main control unit 220, and the storage unit 230 may respectively perform the operations of the communication processing unit 110, the main control unit 120, and the storage unit 130 provided in the weighing device 1 according to the first embodiment. In this case, the weighing processing unit 221, the process execution switching unit 222, and the display processing unit 223 included in the main control unit 220 according to the second embodiment may respectively perform the same operations as the weighing processing unit 121, the process execution switching unit 122, and the display processing unit 123 included in the main control unit 120 according to the first embodiment. In addition, the blending information storage unit 231 and the input value storage unit 232 included in the storage unit 230 according to the second embodiment may respectively perform the same operations as the blending information storage unit 131 and the input value storage unit 132 included in the storage unit 130 according to the first embodiment. In this case, the controller 200 performs the same operations as the controller 100 described in the first embodiment, so the explanation of the second embodiment applies to the explanation of the first embodiment and will not be repeated.

[0124] With this configuration, the display control device 1A of this embodiment also communicates with the weighing device 2A via the communication processing unit 210, and can execute the same operations as the procedures described in FIG. 4 to FIG. 18 in the first embodiment.

[0125] <3.2.

In this way, when the weighing device 2A is a hanging scale, the weight of the object to be weighed can be measured even on a non-level surface regardless of the size of the object to be weighed. In addition, when the weighing device 2A is a top-pan type electronic scale, the weight of the object to be weighed can be measured with high accuracy. Note that, as long as it is capable of communicating with the display control device 1A, the weighing system 1000 may include weighing devices 2B, 2C, etc. other than the weighing device 2A, as shown in FIG. 19.

[0126] Furthermore, the weighing system 1000 may be configured so that the weighing device 1 and the weighing instrument 2A of the first embodiment are communicatively connected. In this case, the weighing device 1 communicates with the weighing instrument 2A and functions as a display control device that executes the same operations as those described in Figures 4 to 18. Furthermore, in this case, the screen displayed on the operation panel 65 of the weighing device 1 may be different between when a weighing operation is performed with the weighing device 1 and when a weighing operation is performed with the weighing instrument 2A.

[0127] <<4. Other embodiments>> Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments. It will be understood by those skilled in the art that these embodiments are merely examples and that various modifications are possible without departing from the scope and spirit of the present invention.

[0130] <<5. Summary of the embodiment>> [Technical field] The present invention relates to a display control device that controls the display of a screen displayed when an object to be weighed is weighed, a weighing device, a weighing system, and a control program. [Background technology] Conventionally, in the weighing work of an item, a weighing device is known that allows a user to input a numerical value and register the input value as the weight of the item instead of using a scale to weigh the item. For example, Patent Document 1 discloses a weighing device that registers the weight of an item by inputting the weight of a material that has already been measured without measuring it on a weighing plate. [Prior art document] [Patent documents] [Patent Document 1] JP 2006-308298 A [Summary of the Invention] [Problem to be solved by the invention] In Patent Document 1, an identifier for identifying whether a value measured using a scale or a value obtained by inputting a number is registered is recorded in the work history on a storage medium together with the weight of the item, container, etc. However, in weighing work, registering the weight of the item, container, etc. by inputting a number is often an irregular response. Therefore, in order to prevent erroneous operation of the weighing device and weighing errors, it is common to make the operation of allowing the weight of the item, container, etc. to be input by a number more complicated than the operation of weighing the item, container, etc. using a scale. Therefore, in Patent Document 1, when changing the weight of an item, container, etc., the user must determine whether the weight value to be changed was registered by weighing on a scale or by inputting a quantity in order to prevent unnecessary number input operations. In other words, in order for the user to determine whether the weight of an item, container, etc. was registered by weighing on a scale or by inputting a quantity, it is necessary to refer to the work history, which becomes a factor that complicates the weighing work. The present invention has been made to solve the above problems, and has an object to improve the productivity of weighing operations. [Means for solving the problem] (1) One aspect of this embodiment is a display control device connected to a weighing unit that weighs the weight of an object to be weighed, an operation unit that allows a quantity to be input, and a display unit that can display weight information regarding the weight of the object to be weighed, and is characterized in that it includes a display processing unit that executes a first mode in which first information including a measurement value of the weight of the object to be weighed weighed by the weighing unit is displayed on the display unit in a first aspect, and a second mode in which second information including an input value of the weight of the object to be weighed inputted by the operation unit is displayed on the display unit in a second aspect different from the first aspect. According to the above configuration, the display mode of the input value is different from the display mode of the measured value of the weight of the weighing object, so the user can easily determine whether the weight displayed on the display unit is the input value or the measured value. Furthermore, when the weight of the weighing object is input as a number, the user is given a stronger impression that he or she can manipulate the displayed value. Therefore, unlike conventional weighing devices, there is no need to check the work history, and the productivity of the weighing work can be improved. (2) One aspect of the present embodiment is the display control device according to (1), further comprising a process execution switching unit that switches between the first mode and the second mode. According to the above configuration, the display mode of the weight information can be switched between the first mode and the second mode by operating the quantity input execution key or the quantity input release key. Therefore, the user can check with a simpler operation whether the weight displayed on the operation panel is the quantity input value or the measured value. (3) One aspect of this embodiment is the display control device described in (2), wherein the operation unit and the display unit are an integrally formed touch panel, and the display processing unit causes the display unit to display number input keys including a plurality of soft keys that can input the weight of the object to be weighed in units when the process execution switching unit switches from the first mode to the second mode. According to the above configuration, when the quantity entry execution key is operated, the quantity entry key is displayed on the measurement screen, so that the display area of ​​the operation panel can be used effectively. (4) One aspect of this embodiment is the display control device described in (3), wherein the input value is a first input value, and the display processing unit is capable of executing a display switching process to switch the first input value displayed on the display unit in the second mode to a second input value that is input as a numeric value after the first input value is displayed, and when first area operation information regarding an operation to the first area is received while the first input value is displayed in a first area of ​​the display unit, the display control unit causes the numeric value input key to be displayed on the display unit. According to the above configuration, the weight display area in which the value is displayed in the second mode is used as a trigger key for editing the weight of the object to be weighed whose quantity has been input, so that the weight of the object to be weighed whose quantity has been input can be edited again with a simpler operation, and the re-edited weight can be used in the weighing work. Therefore, the productivity of the weighing work can be improved compared to conventional weighing devices. (5) One aspect of this embodiment is the display control device described in (4), wherein the display processing unit displays difference information regarding the difference between the weight setting value preset for each of the objects to be weighed and the measurement value or the input value in a second area different from the first area on the display unit, and the digit input key is displayed in at least a portion of the second area. According to the above configuration, when the number entry execution key is operated, the number entry key is displayed so as to overlap with the indicator, thereby making it possible to effectively utilize the display area of ​​the operation panel. (6) One aspect of this embodiment is the display control device described in (5), wherein the display processing unit is configured to, in the second mode, when a number input is performed using the number input key before the first area is operated, display the input number in the second area in a third aspect, and when a number input is performed using the number input key after the first area is operated, display the input number in the second area in a fourth aspect different from the third aspect. According to the above configuration, when performing a weighing operation, the user can accurately determine which value is being input, thereby improving the user experience during the weighing operation. (7) One aspect of this embodiment is a display control device according to any one of (4) to (6), wherein the operation unit includes a switching key that switches the display of the digit-register input keys on the display unit between a displayed state and a hidden state, and the display processing unit, when receiving switching operation information regarding the operation of the switching key from the operation unit, executes a first switching process of switching the digit-register input keys from the displayed state to the hidden state, or a second switching process of switching the digit-register input keys from the hidden state to the displayed state, and in the second switching process, when a digit-register input is performed using the digit-register input key before switching to the hidden state, displays the input digit together with the digit-register input key on the display unit. According to the above configuration, when weighing work is temporarily interrupted and then resumed, it is possible to continue to use the value that was input before the interruption, thereby improving the productivity of the weighing work. (8) One aspect of this embodiment is a display control device described in any one of (2) to (7), wherein the display processing unit, when switching from the first mode to the second mode while weighing is being performed by the weighing unit, displays a confirmation screen on the display unit to confirm the execution of the second mode, and executes the second mode when confirmation operation information regarding an operation to confirm the execution of the second mode on the confirmation screen is received. According to the above configuration, for example, when the weighing unit is trying to input the weight of the weighing object by mistake while the weighing object is being weighed, the user is not required to perform a process that is unnecessary for the weighing operation, thereby further improving the productivity of the weighing operation. Also, it is possible to provide a weighing device that complies with the standards set forth in the Measurement Act. (9) One aspect of the present embodiment is a display control device described in any one of (1) to (8), wherein the second aspect is a display aspect in which the input value is underlined. According to the above configuration, the display mode of the input value is different from the display mode of the measured weight of the weighing object, so the user can easily determine whether the weight displayed on the display unit is the input value or the measured value. Therefore, unlike conventional weighing devices, there is no need to check the work history, and the productivity of weighing work can be improved. (10) One aspect of the present embodiment is a display control device according to any one of (1) to (9), characterized in that the display control device includes the operation unit and the display unit. The above configuration provides the same effects as (1) to (9). (11) One aspect of the present embodiment is the display control device according to any one of (1) to (10), characterized in that it includes the measuring unit. The above configuration provides the same effects as (1) to (10). (12) One aspect of this embodiment is a weighing device including a display control device according to any one of (1) to (11). The above configuration provides the same effects as (1) to (11). (13) One aspect of this embodiment is a weighing system including a display control device according to any one of (1) to (11). The above configuration provides the same effects as (1) to (11). (14) One aspect of the present embodiment is a control program for a display control device connected to a weighing unit that weighs the weight of an object to be weighed, an operation unit that allows a quantity to be input, and a display unit that allows weight information regarding the weight of the object to be weighed, the control program causing a computer to execute a first mode in which first information including a measurement value of the weight of the object to be weighed weighed by the weighing unit is displayed on the display unit in a first aspect, and a second mode in which second information including an input value of the weight of the object to be weighed inputted by the operation unit is displayed on the display unit in a second aspect different from the first aspect. According to the above configuration, as in (1), the display mode of the input value is different from the display mode of the measured weight of the object to be weighed, so the user can easily determine whether the weight displayed on the display unit is the input value or the measured value. Therefore, unlike conventional weighing devices, there is no need to check the work history, and the productivity of weighing work can be improved. [Explanation of symbols]
