[0007] Patent Document 1: International Publication No. 2021 / 002226

[0008] Patent Document 1 lists examples with relatively few processes, but depending on the product, there are cases where the number of processes from raw materials to manufactured products, including the supply chain, ranges from hundreds to thousands, or even thousands. In addition, there are various methods such as adding processes, integrating processes, and branching processes. In this way, there are many cases where the number of processes in product manufacturing is large and complicated, and it is not easy to accurately grasp such processes. Summary of the invention

[0009] An object of the present disclosure is to provide an information processing device, a manufacturing history display system, a manufacturing history display method, and a manufacturing history display program that can easily grasp the process related to the manufacturing of a product.

[0010] The present disclosure adopts the following technical means to solve the above-mentioned problems. The reference numerals in parentheses in the claims and the clauses are examples of the correspondence relationship with the specific elements described in the embodiment described later as one mode, and do not limit the technical scope of the present disclosure.

[0011] An information processing device according to one embodiment of the present invention comprises: a reading unit, which reads supplementary information associated with manufacturing history information of a product and attached to the above-mentioned product; an acquisition control unit, which acquires the above-mentioned manufacturing history information associated with the above-mentioned supplementary information read by the above-mentioned reading unit from a server; and a display control unit, which causes the above-mentioned manufacturing history information acquired by the above-mentioned acquisition control unit to be displayed on a display unit, wherein the above-mentioned manufacturing history information is information that records a plurality of process information representing processes related to the manufacture of the above-mentioned product in a time series, and the above-mentioned display control unit causes the above-mentioned process information to be displayed on the above-mentioned display unit in accordance with each of the above-mentioned process information included in the above-mentioned manufacturing history information, and causes the above-mentioned process information displayed on the above-mentioned display unit to migrate in a time series according to the operation of the user.

[0012] This structure obtains manufacturing history information from a server by reading the attached information attached to the product, and displays it on the display unit. Manufacturing history information is information that records multiple process information representing processes related to the manufacture of a product in a time series. Manufacturing history information contains hundreds, thousands or more than thousands of process information when manufacturing a product, and also contains branches of processes and integrated layer structures (tree structures). Even if a person wants to illustrate the history through a diagram in order to grasp such a manufacturing history, it is not easy to illustrate a huge number of processes. In addition, even if it is possible to illustrate, it is difficult for a person to grasp the content of each process based on the diagram.

[0013] Therefore, according to this configuration, the process information is displayed on the display unit according to each process information included in the manufacturing history information, and the process information displayed on the display unit is shifted in time series according to the user's operation. Thus, the user can grasp the content of each process and the time series change of the process. Therefore, this configuration makes it easy to grasp the manufacturing process of the product.

[0014] In the above-mentioned information processing device, the above-mentioned acquisition control unit may acquire the above-mentioned process information before and after the above-mentioned process information displayed on the above-mentioned display unit from the above-mentioned server. According to this structure, since the process information that may be displayed on the display unit is acquired from the server in advance, the display of the process information can be accelerated.

[0015] In the above-mentioned information processing device, the migration history of the above-mentioned process information displayed on the above-mentioned display unit can also be stored. The above-mentioned display control unit uses the latest above-mentioned process information as the start of display, and when the display is migrated from the downstream side of the process to the upstream side and then returned to the downstream side of the process again, the above-mentioned process information different from the above-mentioned migration history is not displayed on the above-mentioned display unit.

[0016] According to this configuration, when the display is returned from the upstream side of the process to the downstream side after the upstream side of the process is displayed, a process different from the display path to the upstream side of the process will not be displayed. Therefore, this configuration can prevent the display of the manufacturing process of other products different from the original product.

[0017] In the above information processing device, the display control unit may shift the process information displayed on the display unit according to a left-right operation of the display unit by a user. According to this configuration, the user can easily understand the process and operability is improved.

[0018] In the above information processing device, the display control unit may start displaying the latest process information and display the separation degree between the process information displayed on the display unit and the latest process information on the display unit. According to this configuration, the user can easily understand the process displayed on the display unit.

[0019] In the above information processing device, the display control unit may cause the display unit to display an operation image for returning the display on the display unit to the latest process information. According to this configuration, the user can easily understand the process and the operability is improved.

[0020] In the above-mentioned information processing device, the process information may include the amount of carbon dioxide emitted in each of the above-mentioned processes, and the above-mentioned display unit may display at least one of the amount of carbon dioxide emitted in each of the above-mentioned processes and the total amount of carbon dioxide emitted in the above-mentioned processes so far. According to this configuration, carbon footprint tracking is achieved through manufacturing history information, and the user can grasp the amount of carbon dioxide emitted in the manufacturing process.

[0021] In the above-mentioned information processing device, the above-mentioned process information displayed on the above-mentioned display unit may include a branch of the above-mentioned process that can be selected by a user. According to this structure, the user can easily understand the process, and the operability is improved.

[0022] In the above-mentioned information processing device, the above-mentioned display control unit may cause the above-mentioned display unit to display an operation image (54) for displaying an image showing a transportation route when the above-mentioned display unit displays the above-mentioned process information related to transportation. According to this configuration, the user can understand the transportation route of the product.

[0023] In the above-mentioned information processing device, the operation method for changing the display of the above-mentioned process information may be changed. According to this configuration, the operability for the user is improved.

[0024] A manufacturing history display system of one embodiment of the present invention comprises: a server storing manufacturing history information that records, in time series, a plurality of process information representing processes related to the manufacture of a product; and an information processing device that obtains the manufacturing history information associated with the above-mentioned additional information from the server by reading additional information associated with the above-mentioned manufacturing history information and attached to the above-mentioned product, and displays the above-mentioned history information on a display unit. The above-mentioned information processing device displays the above-mentioned process information on the above-mentioned display unit according to each of the above-mentioned process information included in the above-mentioned manufacturing history information obtained from the above-mentioned server, and causes the above-mentioned process information displayed on the above-mentioned display unit to migrate in time series according to the operation of the user.

[0025] A manufacturing history display method according to one aspect of the present invention comprises: a first step, in which a reading unit reads supplementary information associated with the manufacturing history information of a product and attached to the above-mentioned product; a second step, in which an acquisition control unit acquires the above-mentioned manufacturing history information associated with the above-mentioned supplementary information read by the above-mentioned reading unit from a server; and a third step, in which the above-mentioned manufacturing history information acquired by the above-mentioned acquisition control unit is displayed on a display unit, wherein the above-mentioned manufacturing history information is information that records a plurality of process information representing processes related to the manufacture of the above-mentioned product in a time series, and the above-mentioned third step displays the above-mentioned process information on the above-mentioned display unit according to each of the above-mentioned process information contained in the above-mentioned manufacturing history information, and causes the above-mentioned process information displayed on the above-mentioned display unit to migrate in a time series according to the operation of the user.

[0026] A manufacturing history display program of one mode of the present invention enables a computer provided in an information processing device to function as: a reading unit, which reads supplementary information associated with the manufacturing history information of a product and attached to the product; an acquisition control unit, which acquires the manufacturing history information associated with the supplementary information read by the reading unit from a server; and a display control unit, which causes the manufacturing history information acquired by the acquisition control unit to be displayed on a display unit, wherein the manufacturing history information is information that records a plurality of process information representing processes related to the manufacture of the product in a time series, and the display control unit causes the process information to be displayed on the display unit in accordance with each process information included in the manufacturing history information, and causes the process information displayed on the display unit to migrate in a time series according to the operation of the user.

[0036] Hereinafter, the embodiments of the present disclosure will be described with reference to the accompanying drawings. In addition, the embodiments described below are embodiments that illustrate an example of the implementation of the present disclosure, and the present disclosure is not limited to the specific configurations described below. When implementing the present disclosure, a specific configuration corresponding to the embodiments can be appropriately adopted.

[0037] Figure 1 1 is a schematic diagram of the manufacturing history display system 10 according to the present embodiment. The manufacturing history display system 10 according to the present embodiment includes a mobile terminal device 12 and a server 14 .

[0038] The mobile terminal device 12 is provided with a camera 20 (see Figure 3) and an information processing device such as a smartphone or tablet terminal having a display unit 22 such as a touch panel display. In addition, the mobile terminal device 12 is not limited thereto, and as long as it can read the additional information 18 of the product 16 described later (as an example, a QR code) and display the process information, it can also be a dedicated device for displaying process information, or a reading device embedded in an existing manufacturing device for manufacturing the product 16 can be used.

[0039] The mobile terminal device 12 uses the camera 20 to capture an image of the attached information 18 attached to the product 16 , and reads the recorded content of the attached information 18 .

[0040] The attached information 18 is an information code associated with the manufacturing history information of the product 16 and attached to the product 16. Although the attached information 18 of the present embodiment is a QR code as an example, it is not limited to this, and may also be an information code such as other two-dimensional codes or one-dimensional codes such as barcodes. The attached information 18 records the query destination of the manufacturing history information of the attached product 16 (IP address or URL of the server 14, etc.) and the individual information of the product, both or one of them. In addition, the manufacturing history information is also information for tracing the process of the product 16 from manufacturing to consumption, and is referred to as traceability information in the following description.

[0041] The traceability information is information that records multiple process information related to the manufacturing process of the product 16 in time series, and is stored in the server 14. The product 16 refers to raw materials, parts manufactured by processing raw materials, and final products combining multiple parts, and it takes various forms during its manufacturing process.

[0042] Figure 2 Schematic diagram showing the manufacturing process of a vehicle battery as a final product as an example. In the following description, the upstream side of the process is also referred to as the front process, and the downstream side of the process is also referred to as the back process. Figure 2 As shown, in order to manufacture automotive batteries, the supply chain is also included, and various processes are required, such as ordering various raw materials, processing into parts, processing from raw materials to parts, assembling from parts to final products, transporting raw materials or parts, and inspecting parts or final products. In addition, there are various methods such as adding processes, integrating processes, and branching processes. In addition, the integration of processes refers to the method of making multiple previous processes into one subsequent process. The branching of processes refers to the method of making one previous process into multiple subsequent processes.

[0043] In addition, although Figure 2Although not shown, for example, in the raw material ordering process, the parts processing process, etc., there may be a branch to the manufacturing process of other products 16. The other products 16 mentioned here include not only the company's products 16 but also other companies' products 16. In addition, the traceability information may include a series of processes until the used product 16 is recycled and reused and the product 16 is manufactured from the recycled materials.

[0044] The server 14 accumulates the traceability information by sequentially appending data related to the manufacturing process of each product 16 as process information to the traceability information in a time series. Each process information includes the content of the process, the registration time of the process information, the product name of the product 16, information related to the supply chain (company name, manufacturing base name, location information of the manufacturing base location), and the transportation route of the product 16. When accumulating the traceability information of the server 14, in addition to the usual database, a data tampering prevention method such as blockchain can also be used.

[0045] In addition, each process information includes information such as when and where the process was performed, and the amount of carbon dioxide (CO2) emitted in the process. In addition, the amount of carbon dioxide emitted includes not only the amount of carbon dioxide in the process directly related to manufacturing, but also the amount of carbon dioxide emitted by transportation equipment such as ships or trucks due to the transportation of the product 16, and the amount of carbon dioxide emitted in indirect departments not directly related to manufacturing. In this way, carbon footprint tracking based on traceability information is achieved.

[0046] As an example, the management of traceability information in the present embodiment uses blockchain technology to prevent tampering of traceability information. Specifically, for example, the server 14 generates hash values ​​of data related to each process of the product 16, and uses these data (hash values) as a block to embed them in the last block of the blockchain. In addition, the server 14 repeatedly calculates the hash value reflecting the manufacturing process so far according to the progress of the manufacturing process of the product 16. As a result, the hash value provided according to each manufacturing process of the product 16 becomes a value (Merkle path) reflecting all the manufacturing processes so far. As a result, the traceability information becomes a state associated with the process information of the product 16 saved using the blockchain. In addition, the server 14 of the present embodiment generates attached information 18 that records the hash value together with the query destination of the traceability information of the attached product 16, and outputs it in a form that can be attached to the product 16.

[0047] A QR code as the attached information 18 is attached to each product 16 of each process. In addition to being directly attached to the product 16, the attached information 18 may also be attached to a container storing the product 16 or a label for managing the product 16. Figure 2When a plurality of processes (A11 to A14) are integrated as in process A1 of the embodiment, or when one process is branched, the attached information 18 is regenerated by the server 14. In this case, the manufacturer of the product 16 for which the attached information 18 is regenerated outputs the QR code to a paper medium or the like, and attaches it to each product 16. The new generation of the attached information 18 is not limited to the case of integration or branching of the generation process, and can be performed as appropriate.

[0048] The mobile terminal device 12 photographs the attached information 18 attached to the product 16 through the camera 20, and obtains the traceability information indicating the manufacturing process of the product 16 from the server 14 based on the record content (query destination) obtained by reading the attached information 18. Then, the mobile terminal device 12 displays the traceability information obtained from the server 14 on the display unit 22.

[0049] Here, the manufacturing history shown in the traceability information includes hundreds, thousands or more process information when manufacturing a product 16, and also includes the branching and integrated layer structure (tree structure) of the process. Figure 2 It is not easy to illustrate the manufacturing history in such a way that the huge number of processes in a tree structure are illustrated. In addition, even if the diagram can be drawn, it is difficult for the person to understand the content of each process from the diagram. Moreover, it is very difficult for the person who draws the diagram to understand where to observe the manufacturing history, etc.

[0050] Therefore, the mobile terminal device 12 of this embodiment displays each process information included in the traceability information on the display unit 22, and the user operates the display unit 22 to migrate the process information displayed on the display unit 22 in a time series. As a result, the user can understand the content of each process and the time series change of the process. Therefore, the mobile terminal device 12 of this embodiment can make it easy to understand the manufacturing process of the product 16. In addition, as an example, the mobile terminal device 12 of this embodiment does not have Figure 2 A function to display a graph showing an overall image of the traceability information as shown.

[0051] Figure 3 This is a functional block diagram related to the display of traceability information by the manufacturing history display system 10.

[0052] The mobile terminal device 12 includes, in addition to the camera 20 and the display unit 22 , a communication unit 24 , a storage unit 26 , a reading unit 28 , a process information acquisition control unit 30 , and a display control unit 32 .

[0053] The camera 20 has a photographing function and photographs the attached information 18 attached to the product 16 in the present embodiment.

[0054] The display unit 22 is, for example, a touch panel display, and displays various data or accepts operations on the mobile terminal device 12 by the user.

[0055] The communication unit 24 sends and receives information with other information processing devices such as the server 14. In addition, the communication unit 24 of this embodiment sends and receives information with the server 14 via the communication unit 40 provided in the server 14. The storage device 42 provided in the server 14 stores the traceability information of the product 16.

[0056] The storage unit 26 stores various data such as a program (application program) related to reading of the attached information 18 and display of process information, and process information acquired from the server 14 .

[0057] The reading unit 28 reads the attached information 18 (QR code) captured by the camera 20. The reading unit 28 performs a decoding process for deciphering information recorded in the read attached information 18.

[0058] The process information acquisition control unit 30 acquires the traceability information associated with the attached information 18 read by the reading unit 28 from the server 14 via the communication unit 24. In addition, the process information acquisition control unit 30 of the present embodiment does not acquire all the traceability information from the server 14 at one time, but sequentially acquires the process information before and after the process information displayed on the display unit 22 from the server 14. The process information acquired from the server 14 is stored in the storage unit 26. Thus, the time required for display can be shortened.

[0059] The display control unit 32 controls the display unit 22 to display various images. The display control unit 32 of this embodiment displays the traceability information acquired by the process information acquisition control unit 30 on the display unit 22. In addition, the display control unit 32 of this embodiment displays each process information included in the traceability information on the display unit 22, and causes the process information displayed on the display unit 22 to migrate in time series according to the user's operation.

[0060] Next, refer to Figure 4 as well as Figure 5 , the display method of process information based on the mobile terminal device 12 is explained. The user browses the process information by Figure 4 , Figure 5 The process information displayed in this way can help understand the manufacturing process of the product 16. In addition, if the mobile terminal device 12 reads the additional information 18 and obtains the process information from the server 14, an application pre-installed in the mobile terminal device 12 (hereinafter referred to as a "display application") is started and the obtained process information is displayed on the display unit 22.

[0061] Figure 4(A) is a diagram showing process information that is first displayed on the display unit 22 when the supplementary information 18 is read. Figure 4 (B) means that the Figure 4 (A) is a diagram showing process information displayed when the display unit 22 is slid to the right.

[0062] like Figure 4 As shown in (A), the display control unit 32 starts the display with the latest process information. Figure 2 In the case where the manufacturing process G (assembly) is the latest process at the current moment, the additional information 18 of the product 16 is read, and the process information of the manufacturing process G is initially displayed on the display unit 22 as the latest process information. Figure 4 (B) In this way, the process one generation ago compared to the latest process information, that is, the previous (upstream) process of the latest process, is displayed. In this way, in the present embodiment, as an example, by sliding the display unit 22 in the right direction, the process information on the upstream side is migrated and displayed. On the other hand, by sliding the display unit 22 in the left direction, the process information on the downstream side is migrated and displayed. In addition, when the latest process information is displayed, the displayed process information does not migrate even if it is slid in the left direction. If you slide in the right direction, you can move to the previous process, and if you slide in the left direction, you can move to the next process, but this is a method based on the experimental results related to usability and the feelings of many users, and the direction can also be reversed, or it can be changed to the up and down direction.

[0063] In this way, the display control unit 32 changes the process information displayed on the display unit 22 according to the user's left and right operation of the display unit 22. As a result, the user can easily understand the process and the operability is improved. In addition, although in this embodiment, the process information displayed on the display unit 22 is changed by sliding the display unit 22, it is not limited to this. For example, an arrow button for changing the display of the process may be displayed on the display unit 22, and the displayed process information may be changed by clicking the arrow button.

[0064] In order to make it easier for the user to understand the process displayed on the display unit 22, the display control unit 32 of this embodiment starts the display with the latest process information and causes the display unit 22 to display the degree of separation between the process information displayed on the display unit 22 and the latest process information.

[0065] The degree of separation is Figure 4 The generation display column 50 in is displayed as "generation". Figure 4 (A) Since the latest process information is displayed, “latest” in the generation display field 50 is highlighted. Figure 4(B) Since this is process information of the previous generation compared to the latest one, "Previous Generation (1)" in the generation display column 50 is highlighted. Figure 4 In the display state (B), when the user slides to the right, the process information of two generations ago is displayed on the display unit 22, and "two generations ago (1)" in the generation display column 50 is highlighted.

[0066] Furthermore, the display control unit 32 is as follows Figure 4 As shown in (B), an operation image (hereinafter referred to as "latest return button") 52 for returning the display of the display unit 22 to the latest process information is displayed on the display unit 22. Thus, even if the process information on the upstream side is displayed, the latest process information can be displayed on the display unit 22 by operating (clicking) the latest return button 52, so that the user can easily understand the process and the operability is improved. In addition, when the display unit 22 displays the latest process information, the latest return button 52 is not displayed.

[0067] In addition, the display unit 22 displays "Packaging Manufacturing" or "Material Manufacturing" as the name of the displayed process information, the time when the traceability information is registered as detailed process information, the brand name of the product 16, the name of the company that manufactured the product 16, the base name as the manufacturing location, the latitude and longitude indicating the location of the base, material information used, processing information, due diligence, and carbon footprint, etc.

[0068] In addition, at least one of the amount of carbon dioxide (CO2) emitted in each process and the total amount of carbon dioxide emitted in the processes up to that point is displayed on the display unit 22. Thus, carbon footprint tracking is achieved, and the user can grasp the amount of carbon dioxide emitted in the manufacturing process.

[0069] Furthermore, in the mobile terminal device 12 of the present embodiment, information that cannot be completely displayed on one screen of the display unit 22 may be displayed by sliding in the up-down direction or by folding the display.

[0070] Next, the acquisition of process information from the server 14 by the process information acquisition control unit 30 of this embodiment will be described. As described above, the process information acquisition control unit 30 acquires process information before and after the process information displayed on the display unit 22 from the server 14 .

[0071] The process information acquisition control unit 30 of this embodiment acquires the process information of the previous generation at the same time when acquiring the latest process information. Figure 4(B) When the process information of the previous generation is displayed on the display unit 22, the process information acquisition control unit 30 acquires the process information of two generations ago as the next upstream process information from the server 14. Thus, when the process information of two generations ago is displayed on the display unit 22, the mobile terminal device 12 has already acquired the process information, so the process information of two generations ago is displayed on the display unit 22 with the slide in the right direction. In addition, when the process information of the previous generation is displayed on the display unit 22, the mobile terminal device 12 has already acquired the latest process information, so the latest process information is displayed on the display unit 22 with the slide in the left direction.

[0072] Thus, the mobile terminal 12 acquires process information before and after the process information displayed on the display unit 22 from the server 14. Therefore, the mobile terminal 12 acquires process information that may be displayed on the display unit 22 from the server 14 in advance, so that the process information can be displayed at a higher speed.

[0073] Next, refer to Figure 5 The case where there is a branch when the display is moved from the later process to the previous process will be described. In addition, the branch mentioned here means that in the actual process, a plurality of upstream processes are integrated into one downstream process.

[0074] Figure 5 (A) shows a case where there are three transport processes from the latest process. In this case, "A transport", "B transport" and "C transport" are displayed together with the transported product 16 (product name) as branches for selecting one of the three transport processes. The user selects one of them, such as Figure 5 As shown in (B), the display unit 22 displays the previous generation of transportation process.

[0075] In this way, the process information displayed on the display unit 22 includes branches of the process that the user can select, so that the user can easily understand the process and the operability is improved. Figure 5 The generation display column 50 has the number of branches displayed in "()" like "previous generation (3)". In addition, a process without a branch is displayed as "(1)". Thus, the user can easily recognize whether the displayed process information is a branching process.

[0076] In addition, when the process information displayed on the display unit 22 includes a branching process before and after, the process information acquisition control unit 30 acquires all the branching processes from the server 14. Figure 5 In the example of (A), all the process information of "A transport", "B transport" and "C transport" is acquired from the server 14. Thus, the display unit 22 can display the process information at high speed regardless of the process selected by the user.

[0077] In addition, when the display unit 22 displays the transport process, the display control unit 32 causes the display unit 22 to display an operation image (hereinafter referred to as a "transport route display button") 54 for displaying an image showing the transport route. When the user operates (clicks) the transport route display button 54, the transport route in the transport process is displayed together with the map information on the display unit 22. Thus, the user can understand the transport route of the product 16.

[0078] Next, refer to Figure 6 A description will be given of a case where the display is shifted from the downstream side of the process to the upstream side, and the display is returned to the downstream side of the process again.

[0079] like Figure 6 As shown, there is a case where there is no branch when the process is transferred from the downstream side to the upstream side, and on the other hand, there is a case where there is a branch (process C1, C2, C3) when the process is transferred from the upstream side to the downstream side. Such a branch is, for example, a case where the raw materials ordered are transported separately for the manufacture of multiple different other products 16, and the raw material ordering process may be shared as a manufacturing process of a product 16 different from the original product 16 in the traceability information.

[0080] If such a branch is included in the manufacturing history information, for example, when the display is moved from the downstream side of the process to the upstream side and then returned to the downstream side of the process, a branch different from the manufacturing process of the original product 16 may be selected, and the manufacturing process of another product 16 may be displayed on the display unit 22. In addition, the other products 16 may also include products 16 of other companies different from the company.

[0081] If you refer to Figure 6 , the manufacturing process of the original product 16 browsed by the user is process A~B~C1~E1. Furthermore, if the user returns the display to the downstream side of process C1 after displaying the upstream side of process B, assuming that C2 or process C3 can be selected as the branch process after process B, there is a possibility that the user browses the path of the manufacturing process of other products 16.

[0082] If the manufacturing process of other products 16 is displayed, the user is not only unable to browse the manufacturing process of the product 16 that is originally intended to be displayed, but also has the possibility of unnecessarily browsing the manufacturing process of other companies' products 16. Therefore, such browsing of the manufacturing process of other products 16 must be prevented.

[0083] Therefore, in the manufacturing history display system 10 of the present embodiment, a transition history of process information displayed on the display unit 22 is stored. The transition history is stored in the mobile terminal device 12 or the server 14. Furthermore, when the display control unit 32 makes the transition from the downstream side of the process to the upstream side and returns the display to the downstream side of the process with the latest process information as the start of the display, the display control unit 32 does not display process information different from the transition history on the display unit 22.

[0084] That is, in Figure 6 In the case where the display returns to the downstream process after displaying the process on the upstream side of process B, the user cannot select the display of process C2 and C3, and only the process on the downstream side of process C1 is displayed. That is, when the mobile terminal device 12 returns the display from the upstream side of the process to the downstream side after displaying the upstream side of the process, the process that is different from the display path to the upstream side of the process is not displayed, but the process that is the same as the display path is displayed.

[0085] Therefore, in the manufacturing history display system 10 of this embodiment, it is possible to prevent the display of the manufacturing process of another product 16 different from the original product 16. In addition, by storing the transition history, the user can quickly search for the process information to be displayed on the display unit 22.

[0086] Furthermore, the mobile terminal device 12 of the present embodiment can change the operation method for transitioning the display of the process information by setting by the user.

[0087] By changing the settings, for example, by sliding in the right direction, the process information on the upstream side can be displayed, and by sliding in the left direction, the process information on the downstream side can be displayed. In addition, by sliding in the up-down direction, the process information displayed on the display unit 22 can be moved up-down. In addition, instead of performing gesture operations such as sliding, arrow buttons can be displayed and the process information displayed on the display unit 22 can be moved by operating the arrow buttons. In this way, the operation method can be changed according to the generation and preferences of the user, so the operability for the user is improved.

[0088] Figure 7 This is a flowchart showing the flow of the manufacturing history display process executed by the mobile terminal device 12. The manufacturing history display process is executed by a program (display application) stored in a recording medium such as the storage unit 26 provided in the mobile terminal device 12. In addition, by executing the program, a method corresponding to the program is executed.

[0089] First, in step S100 , the mobile terminal device 12 captures the attached information 18 of the product 16 using the camera 20 , and the reading unit 28 reads the content of the attached information 18 .

[0090] In the next step S102 , the process information acquisition control unit 30 acquires the latest process information and the previous generation of process information from the server 14 via the communication unit 24 , and stores the acquired information in the storage unit 26 .

[0091] In the next step S104 , the display control unit 32 causes the display unit 22 to display the latest process information.

[0092] In the next step S106 , it is determined whether a slide operation has been performed on the display unit 22 . If the determination is affirmative, the process proceeds to step S108 , and if the determination is negative, the process proceeds to step S116 .

[0093] In step S108 , the display control unit 32 causes the process information displayed on the display unit 22 to transition according to the slide operation.

[0094] In the next step S110, the process information acquisition control unit 30 determines whether process information of a process before or after the process information displayed on the display unit 22 has been acquired, and moves to step S114 if the determination is affirmative. On the other hand, if the determination is negative, the process moves to step S112.

[0095] In step S112 , the process information acquisition control unit 30 acquires process information of a preceding process or a succeeding process of the process information displayed on the display unit 22 from the server 14 , and stores the acquired information in the storage unit 26 .

[0096] In the next step S114 , it is determined whether an operation to end the display application has been performed. If the determination is affirmative, the display application is ended, and if the determination is negative, the process returns to step S106 .

[0097] If a negative determination is made in step S106, the process proceeds to step S116 to determine whether an operation other than the sliding operation has been performed. If a positive determination is made, the process proceeds to step S118, and if a negative determination is made, the process returns to step S106. Other operations include, for example, selection of a branch, operation of the latest return button 52, operation of the transport route display button 54, and operation of changing settings.

[0098] In step S118, processing corresponding to other operations is performed, and the process returns to step S106.

[0099] The present disclosure is described above using the above-mentioned embodiments, but the technical scope of the present disclosure is not limited to the scope described in the above-mentioned embodiments. Various changes or improvements can be made to the above-mentioned embodiments without departing from the scope of the disclosure, and the methods after the changes or improvements are also included in the technical scope of the present disclosure.

[0100] For example, in the above embodiment, the display unit 22 is described as displaying each process information, but it is not limited to this, and it may be a mode in which two or more process information are displayed simultaneously on the display unit 22. In the case of this mode, the mobile terminal device 12 also has the same function as the above embodiment. For example, the process information acquisition control unit 30 acquires the process information before and after the process information displayed on the display unit 22 from the server 14. In addition, when the display is migrated from the downstream side of the process to the upstream side and the display is returned to the downstream side of the process again, the display control unit 32 does not cause the display unit 22 to display the process information different from the migration history.
