CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is based on Japanese Application No. 2022-081543 filed on May 18, 2022, the contents of which are incorporated herein by reference. [Technical field]

[0002] The present disclosure relates to an information processing device, a production history display system, a production history display method, and a production history display program. [Background technology]

[0003] In recent years, there has been an increasing demand for the management of product manufacturing processes and the amount of carbon dioxide emissions during product manufacturing.

[0004] Here, Patent Document 1 describes a supply chain management method that is implemented by a computer and that manages transaction records between traders in a supply chain that is constructed including a plurality of traders.

[0005] Patent Document 1 uses the logistics route of bread as an example, and describes that (1) a seed producer ships wheat seeds to a wheat farmer, (2) the wheat farmer ships wheat grown from the seeds to a flour manufacturer, (3) the flour manufacturer processes the wheat and ships the flour made from it to a bread manufacturer, (4) the bread manufacturer ships the bread made from the flour to a convenience store, and (5) the convenience store sells the procured bread to consumers. In the management method of Patent Document 1, consumers can view transaction records such as the raw materials, processing process, and distribution process by reading the QR code (registered trademark) attached to the bread they purchased. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] International Publication No. 2021 / 002226 Summary of the Invention

[0007] Although Patent Document 1 gives an example with a relatively small number of steps, the number of steps from raw materials to manufacturing a product, including the supply chain, can range from hundreds to thousands or even more depending on the product. There are also various aspects such as adding a process, integrating processes, and branching processes. As such, the number of processes in product manufacturing is often enormous and complicated, and it is not easy to accurately grasp such processes.

[0008] An object of the present disclosure is to provide an information processing device, a production history display system, a production history display method, and a production history display program that enable easy understanding of processes related to the production of a product. [Means for solving the problem]

[0009] The present disclosure employs the following technical means to solve the above problems. The reference symbols in parentheses in the claims and in this section are merely examples showing the corresponding relationship with the specific means described in the embodiments described below as one aspect, and do not limit the technical scope of the present disclosure.

[0010] An information processing device of one embodiment of the present disclosure includes a reading unit that reads auxiliary information that is linked to manufacturing history information of a product and attached to the product, an acquisition control unit that acquires the manufacturing history information linked to the auxiliary information read by the reading unit from a server, and a display control unit that displays the manufacturing history information acquired by the acquisition control unit on a display unit, wherein the manufacturing history information is information in which a plurality of process information indicating processes related to the manufacturing of the product is recorded in chronological order, and the display control unit displays each piece of process information included in the manufacturing history information on the display unit and transitions the process information displayed on the display unit in chronological order in response to operation by a user.

[0011] This configuration reads the attached information attached to the product, obtains the manufacturing history information from the server, and displays it on the display unit. The manufacturing history information is information in which multiple pieces of process information indicating the processes related to the manufacturing of the product are recorded in chronological order. The manufacturing history information contains hundreds, thousands, or even more pieces of process information when manufacturing one product, and has a layered structure (tree structure) that also includes branching and integration of processes. For a person to understand such a manufacturing history, for example, even if one tries to represent the manufacturing history in a diagram, it is not easy to illustrate a huge number of processes. Even if it is possible to illustrate it, it is difficult for a person to understand the content of each process from the diagram.

[0012] Therefore, according to the present configuration, each piece of process information included in the manufacturing history information is displayed on the display unit, and the process information displayed on the display unit is changed in chronological order in response to the user's operation. This allows the user to understand the content of each process and the changes in the process over time. Therefore, this configuration makes it easy to understand the manufacturing process of the product.

[0013] In the information processing device, the acquisition control unit may acquire the process information before and after the process information displayed on the display unit from the server. According to this configuration, the process information that may be displayed on the display unit is acquired in advance from the server, so that the display of the process information can be accelerated.

[0014] In the above-mentioned information processing device, a transition history of the process information displayed on the display unit is stored, and the display control unit starts displaying the latest process information, and when transitioning the display from the downstream side of the process to the upstream side and then returning the display to the downstream side of the process, it is not necessary to display on the display unit the process information that differs from the transition history.

[0015] According to this configuration, when the display is returned from the upstream side of the process to the downstream side after displaying the upstream side of the process, processes different from the display route that led to the upstream side of the process are not displayed. Therefore, this configuration can prevent the display of manufacturing processes of products other than the original product.

[0016] In the information processing device, the display control unit may transition the process information displayed on the display unit in response to a left or right operation by a user. With this configuration, it becomes easier for a user to understand the process and operability is improved.

[0017] In the information processing device, the display control unit may start displaying the latest process information and cause the display unit to display a degree of deviation between the process information being displayed on the display unit and the latest process information. With this configuration, it becomes easier for a user to understand the process being displayed on the display unit.

[0018] In the information processing device, the display control unit may cause the display unit to display an operation image for returning the display of the display unit to the latest process information. With this configuration, it becomes easier for a user to understand the process and operability is improved.

[0019] In the above information processing device, the process information may include the amount of carbon dioxide emitted for each process, and the display unit may display at least one of the amount of carbon dioxide emitted for each process and the total amount of carbon dioxide emitted in the processes up to that point. With this configuration, carbon footprint tracing is realized using manufacturing history information, and a user can grasp the amount of carbon dioxide emitted in the manufacturing process.

[0020] In the information processing device, the process information displayed on the display unit may include a branch of the process selectable by a user. With this configuration, it becomes easier for a user to understand the process and operability is improved.

[0021] In the above information processing device, the display control unit may cause the display unit to display an operation image (54) for displaying an image showing a transportation route when the process information related to transportation is displayed on the display unit. With this configuration, the user can understand the transportation route of the product.

[0022] In the information processing device, the operation method for transitioning the display of the process information may be changeable. With this configuration, operability for a user is improved.

[0023] A manufacturing history display system of one embodiment of the present disclosure includes a server that stores manufacturing history information that records multiple process information indicating processes related to the manufacturing of a product in chronological order, and an information processing device that reads attached information that is linked to the manufacturing history information and attached to the product, thereby acquiring the manufacturing history information linked to the attached information from the server and displays the history information on a display unit, and the information processing device displays on the display unit each piece of process information included in the manufacturing history information acquired from the server, and transitions the process information displayed on the display unit in chronological order in response to operations by a user.

[0024] A manufacturing history display method of one embodiment of the present disclosure includes a first step of reading attached information linked to manufacturing history information of a product and attached to the product by a reading unit, a second step of acquiring from a server the manufacturing history information linked to the attached information read by the reading unit by an acquisition control unit, and a third step of displaying on a display unit the manufacturing history information acquired by the acquisition control unit, wherein the manufacturing history information is information in which a plurality of process information indicating processes related to the manufacturing of the product is recorded in chronological order, and the third step displays on the display unit each piece of process information included in the manufacturing history information, and transitions the process information displayed on the display unit in chronological order in response to an operation by a user.

[0025] A manufacturing history display program of one embodiment of the present disclosure causes a computer provided in an information processing device to function as a reading unit that reads auxiliary information linked to the manufacturing history information of a product and attached to the product, an acquisition control unit that acquires from a server the manufacturing history information linked to the auxiliary information read by the reading unit, and a display control unit that displays the manufacturing history information acquired by the acquisition control unit on a display unit, wherein the manufacturing history information is information in which a plurality of process information indicating processes related to the manufacturing of the product is recorded in chronological order, and the display control unit displays on the display unit each piece of process information included in the manufacturing history information, and transitions the process information displayed on the display unit in chronological order in response to operation by a user.

[0028] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. Note that the embodiment described below shows an example of a case where the present disclosure is implemented, and the present disclosure is not limited to the specific configuration described below. When implementing the present disclosure, a specific configuration according to the embodiment may be appropriately adopted.

[0029] 1 is a schematic diagram of a production history display system 10 according to the present embodiment. The production history display system 10 according to the present embodiment includes a mobile terminal device 12 and a server 14.

[0030] The mobile terminal device 12 is an information processing device such as a smartphone or tablet terminal equipped with a camera 20 (see FIG. 3) and a display unit 22 such as a touch panel display. Note that the mobile terminal device 12 is not limited to this, and may be a dedicated device for displaying process information, or a reading device incorporated in an existing manufacturing device for manufacturing the product 16, as long as it is configured to read auxiliary information 18 (e.g., a QR code) of the product 16 described later and display the process information.

[0031] The mobile terminal device 12 captures an image of the attached information 18 attached to the product 16 using the camera 20 and reads the recorded contents of the attached information 18 .

[0032] The attached information 18 is an information code that is linked to the manufacturing history information of the product 16 and that is attached to the product 16. The attached information 18 in this embodiment is a QR code as an example, but is not limited to this and may be other information codes such as two-dimensional codes or one-dimensional codes such as barcodes. The attached information 18 records both or either one of the contact information for the attached manufacturing history information of the product 16 (such as the IP address or URL of the server 14) and individual information of the product. The manufacturing history information is also information that enables the process of the product 16 to be traced from its manufacture to its consumption, and is referred to as traceability information in the following description.

[0033] The traceability information is information in which multiple pieces of process information indicating the steps involved in the manufacture of the product 16 are recorded in chronological order, and is stored in the server 14. The product 16 is a raw material, a part manufactured by processing the raw material, a final product made by combining multiple parts, etc., and takes various forms during the manufacturing process.

[0034] FIG. 2 is a schematic diagram showing a manufacturing process in which an on-board battery is an end product as an example. In the following description, the upstream side of the process is also called a front-end process, and the downstream side of the process is also called a back-end process. As shown in FIG. 2, in order to manufacture an on-board battery, various processes are required, including a supply chain, such as procurement of various raw materials, processing into parts, processing of the raw materials into parts, assembly of the parts into end products, transportation of the raw materials and parts, and inspection of the parts and end products. There are also various aspects such as adding a process, integrating a process, and branching a process. Note that integration of a process is an aspect in which multiple front-end processes are integrated into one back-end process. Branching of a process is an aspect in which one front-end process is integrated into multiple back-end processes.

[0035] Although not shown in Fig. 2, for example, the raw material procurement process or the parts processing process may include a branch leading to a manufacturing process of another product 16. The other products 16 mentioned here include not only the company's own products 16 but also other companies' products 16. The traceability information may also include a series of processes from when used products 16 are collected and recycled to when products 16 are manufactured from recycled materials.

[0036] The server 14 accumulates data on the manufacturing process of each product 16 by sequentially adding the data to the traceability information in chronological order as process information. Each piece of process information includes the process content, the date and time of registration of the process information, the product name as the product 16, information on the supply chain (company name, manufacturing base name, and location information of the manufacturing base), the transportation route of the product 16, and the like. When accumulating the traceability information on the server 14, a data tamper-proof method such as a block chain may be used in addition to a normal database.

[0037] Furthermore, each process information includes information on when and where the process was performed, the amount of carbon dioxide (CO2) emitted during the process, etc. The amount of carbon dioxide emitted includes not only the amount of carbon dioxide emitted during processes directly related to manufacturing, but also the amount of carbon dioxide emitted by transportation equipment such as ships and trucks during the transportation of the product 16, and the amount of carbon dioxide emitted in indirect departments not directly related to manufacturing. This makes it possible to trace carbon footprints using traceability information.

[0038] In the present embodiment, the traceability information is managed by using, as an example, a block chain technology in order to prevent the traceability information from being tampered with. Specifically, for example, the server 14 generates hash values ​​of data related to each process of the product 16, and incorporates these data (hash values) into one block, and performs a process of incorporating the block to be linked to the end of the block chain. The server 14 then repeats the calculation of hash values ​​reflecting the manufacturing process up to that point as the manufacturing process of the product 16 progresses. As a result, the hash value provided for each manufacturing process of the product 16 becomes a value (Merkle root) reflecting all the manufacturing processes up to that point. This allows the traceability information to be stored using the block chain so as to be linked to the process information of the product 16. The server 14 in the present embodiment then generates attached information 18 in which the hash value is recorded together with the contact information for the traceability information of the attached product 16, and outputs the attached information in a form that can be attached to the product 16.

[0039] A QR code, which is the attached information 18, is attached to each product 16 in each process. The attached information 18 may be attached directly to the product 16, or may be attached to a container that contains the product 16 or a tag that manages the product 16. The attached information 18 is newly generated by the server 14, for example, when a plurality of processes (A11 to A14) are integrated, such as process A1 in FIG. 2, or when one process branches. In this case, the manufacturer of the product 16 for which the attached information 18 has been newly generated outputs the QR code onto a paper medium or the like and attaches it to each product 16. The generation of new attached information 18 is not limited to cases in which processes are integrated or branched, and may be performed as appropriate.

[0040] The mobile terminal device 12 captures the attached information 18 attached to the product 16 with the camera 20, and acquires traceability information indicating the manufacturing process of the product 16 from the server 14 based on the recorded contents (contact information) obtained by reading the attached information 18. The mobile terminal device 12 then displays the traceability information acquired from the server 14 on the display unit 22.

[0041] Here, the manufacturing history indicated by the traceability information contains hundreds, thousands, or even more process information for manufacturing one product 16, and has a layered structure (tree structure) that also includes branching and integration of processes. For a person to understand such a manufacturing history, for example, even if an attempt is made to illustrate the manufacturing history as shown in FIG. 2, it is not easy to illustrate the enormous number of processes that form a tree structure. Even if it is possible to illustrate it, it is difficult for a person to understand the content of each process from the diagram. Furthermore, even if it is illustrated, it is very difficult for a person to understand which manufacturing history they are looking at.

[0042] Therefore, the mobile terminal device 12 of this embodiment displays each piece of process information included in the traceability information on the display unit 22, and the process information displayed on the display unit 22 changes in chronological order as the user operates the display unit 22. This allows the user to understand the content of each process and the changes in the processes over time. Therefore, the mobile terminal device 12 of this embodiment makes it easy to understand the manufacturing process of the product 16. Note that the mobile terminal device 12 of this embodiment does not have a display function for a diagram showing an overall picture of the traceability information as shown in FIG. 2, for example.

[0043] FIG. 3 is a functional block diagram relating to the display of traceability information in the production history display system 10. As shown in FIG.

[0044] The mobile terminal device 12 includes a camera 20 and a display unit 22 , as well as 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 .

[0045] The camera 20 has an imaging function, and in this embodiment, captures an image of the attached information 18 attached to the product 16 .

[0046] The display unit 22 is, for example, a touch panel display, and displays various data and accepts operations on the mobile terminal device 12 by the user.

[0047] The communication unit 24 transmits and receives information to and from other information processing devices such as the server 14. Note that the communication unit 24 of this embodiment transmits and receives information to and from the server 14 via a communication unit 40 provided in the server 14. Traceability information of the product 16 is stored in a storage device 42 provided in the server 14.

[0048] The storage unit 26 stores a program (application) related to reading the auxiliary information 18 and displaying the process information, and various data such as the process information acquired from the server 14.

[0049] The reading unit 28 reads the auxiliary information 18 (QR code) captured by the camera 20. Then, the reading unit 28 performs a decoding process to decode the information recorded in the auxiliary information 18 that has been read.

[0050] The process information acquisition control unit 30 acquires the traceability information linked to the auxiliary information 18 read by the reading unit 28 from the server 14 via the communication unit 24. Note that the process information acquisition control unit 30 of this embodiment does not acquire all the traceability information from the server 14 at once, but instead acquires process information before and after the process information displayed on the display unit 22 from the server 14 one by one. The process information acquired from the server 14 is stored in the storage unit 26. This makes it possible to shorten the time required for display.

[0051] The display control unit 32 controls the display unit 22 to display various images. The display control unit 32 of this embodiment causes the display unit 22 to display the traceability information acquired by the process information acquisition control unit 30. The display control unit 32 of this embodiment also causes the display unit 22 to display each piece of process information included in the traceability information, and transitions the process information displayed on the display unit 22 in chronological order in response to an operation by a user.

[0052] Next, a display mode of the process information by the mobile terminal device 12 will be described with reference to Fig. 4 and Fig. 5. A user can understand the manufacturing process of the product 16 by viewing the process information displayed as in Fig. 4 and Fig. 5. When the mobile terminal device 12 reads the auxiliary information 18 and acquires the process information from the server 14, an application (hereinafter referred to as a "display application") installed in advance in the mobile terminal device 12 is started, and the acquired process information is displayed on the display unit 22.

[0053] Fig. 4(A) is a diagram showing the process information that is initially displayed on the display unit 22 by reading the auxiliary information 18. Fig. 4(B) is a diagram showing the process information that is displayed when the display unit 22 displaying Fig. 4(A) is swiped rightward.

[0054] As shown in FIG. 4(A), the display control unit 32 starts displaying the latest process information. For example, in FIG. 2, when the manufacturing process G (assembly) is the latest process at the present time, if the attached information 18 of the product 16 is read, the process information of this manufacturing process G is displayed first on the display unit 22 as the latest process information. Then, when the user swipes rightward, a process one generation before the latest process information, that is, a process one generation before the latest process information (upstream side) is displayed as shown in FIG. 4(B). Thus, in this embodiment, as an example, when the display unit 22 is swiped rightward, the upstream process information is shifted and displayed. On the other hand, when the display unit 22 is swiped leftward, the downstream process information is shifted and displayed. Note that even if the latest process information is displayed and the display is swiped leftward, there is no shift in the displayed process information. When the display unit 22 is swiped rightward, the process information can be shifted to the previous process, and when the display unit 22 is swiped leftward, the process information can be shifted to the next process. This is based on the sensibilities of many users based on the results of experiments on usability, but it is also possible to reverse the direction, or to change the direction up or down.

[0055] In this way, the display control unit 32 transitions the process information displayed on the display unit 22 in response to the user's left or right operation on the display unit 22. This makes it easier for the user to grasp the process and improves operability. Note that in this embodiment, the process information displayed on the display unit 22 transitions by swiping the display unit 22, but this is not limiting, and for example, an arrow button for transitioning the display of the process may be displayed on the display unit 22, and the displayed process information may transition by clicking this arrow button.

[0056] In this embodiment, the display control unit 32 starts displaying the latest process information so that the user can easily understand the process displayed on the display unit 22, and causes the display unit 22 to display the degree of deviation between the process information displayed on the display unit 22 and the latest process information.

[0057] This degree of deviation is displayed as "generation" in the generation display field 50 in Fig. 4. In Fig. 4(A), the latest process information is displayed, so "latest" is highlighted in the generation display field 50. In Fig. 4(B), the process information is one generation before the latest, so "one generation before (1)" is highlighted in the generation display field 50. Furthermore, when the user swipes right in the display state of Fig. 4(B), process information from two generations ago is displayed on the display unit 22, and "two generations before (1)" is highlighted in the generation display field 50.

[0058] Furthermore, as shown in Fig. 4(B), the display control unit 32 causes the display unit 22 to display an operation image (hereinafter referred to as a "return to latest button") 52 for returning the display on the display unit 22 to the latest process information. As a result, even if upstream process information is being displayed, the latest process information is displayed on the display unit 22 by operating (clicking) the return to latest button 52, making it easier for the user to understand the process and improving operability. Note that the return to latest button 52 is not displayed when the latest process information is being displayed on the display unit 22.

[0059] In addition, the display unit 22 displays the name of the displayed process information, such as "pack production" or "material production," as well as detailed process information such as the date and time of registration in the traceability information, the product name of the product 16, the name of the company that produced the product 16, the name of the base where the product was produced, the latitude and longitude indicating the location of the base, information on the materials used, processing information, due diligence, carbon footprint, etc.

[0060] In addition, at least one of the amount of carbon dioxide (CO2 amount) 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. This allows tracing of the carbon footprint and allows the user to understand the amount of carbon dioxide emitted in the manufacturing process.

[0061] In the mobile terminal device 12 of this embodiment, information that cannot be displayed on one screen of the display unit 22 may be displayed by swiping up and down or in an accordion display.

[0062] Next, a description will be given of the acquisition of process information from the server 14 by the process information acquisition control unit 30 of this embodiment. 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.

[0063] In this embodiment, when the process information acquisition control unit 30 acquires the latest process information, it also acquires the process information of one generation ago at the same time. Then, as shown in FIG. 4B, when the process information of one generation ago is displayed on the display unit 22, the process information acquisition control unit 30 acquires the process information of two generations ago, which is the next upstream process information, from the server 14. As a result, when the process information of two generations ago is displayed on the display unit 22, the process information of the two generations ago has already been acquired by the mobile terminal device 12, so that the process information of two generations ago is displayed on the display unit 22 together with a swipe to the right. Also, when the process information of one generation ago is displayed on the display unit 22, the latest process information has already been acquired by the mobile terminal device 12, so that the latest process information is displayed on the display unit 22 together with a swipe to the left.

[0064] In this way, the mobile terminal device 12 obtains from the server 14 the process information before and after the process information displayed on the display unit 22. Therefore, since the mobile terminal device 12 obtains in advance from the server 14 the process information that may be displayed on the display unit 22, the display of the process information can be speeded up.

[0065] Next, a case where a branch exists when transitioning the display from a later process to a previous process will be described with reference to Fig. 5. Note that the branch here refers to a case where multiple upstream processes are integrated into one downstream process in the actual process.

[0066] Fig. 5(A) shows a case where the process one generation before the latest process is three transport processes. In such a case, "Transport A", "Transport B" and "Transport C" are displayed together with the product 16 (product name) to be transported as a branch for selecting one of the three transport processes. By selecting one of these, the user can display the transport process one generation before on the display unit 22 as shown in Fig. 5(B).

[0067] In this way, the process information displayed on the display unit 22 includes process branches that the user can select, making it easier for the user to understand the process and improving operability. For processes that include branches, the number of branches is displayed in parentheses, as in "One generation ago (3)" in the generation display field 50 in Fig. 5. For processes with no branches, "(1)" is displayed. This allows the user to easily recognize whether the process information being displayed is a branched process or not.

[0068] Furthermore, when the process information displayed on the display unit 22 includes a process that has a branch before or after it, the process information acquisition control unit 30 acquires all of the branched processes from the server 14. That is, in the example of Fig. 5(A), all of the process information for "Transport A", "Transport B", and "Transport C" is acquired from the server 14. This allows the process information to be displayed on the display unit 22 at high speed, regardless of the process selected by the user.

[0069] Furthermore, when a transportation process is displayed on the display unit 22, the display control unit 32 causes the display unit 22 to display an operation image (hereinafter referred to as a "transportation route display button") 54 for displaying an image showing a transportation route. When a user operates (clicks) the transportation route display button 54, the display unit 22 displays the transportation route in the transportation process together with map information. This allows the user to understand the transportation route of the product 16.

[0070] Next, a case where the display is transitioned from the downstream side of the process to the upstream side and then returned to the downstream side of the process will be described with reference to FIG.

[0071] As shown in Fig. 6, there is no branch when the display transitions from the downstream side to the upstream side of the process, but there are cases where branches (processes C1, C2, C3) occur when transitioning from the upstream side to the downstream side. Such branching occurs, for example, when procured raw materials are transported separately for the manufacture of a plurality of different products 16, and there is a possibility that the procurement process of the raw materials may be shared as a manufacturing process of a product 16 different from the original product 16 in the traceability information.

[0072] If such a branch is included in the manufacturing history information, for example, when the display is transitioned 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 original manufacturing process of the product 16 may be selected, and a manufacturing process of another product 16 may be displayed on the display unit 22. Note that the other products 16 may include products 16 of other companies other than the company's own.

[0073] 6, the manufacturing process of the original product 16 that the user is viewing is comprised of processes A to B to C1 to E1. If the user were to be able to select process C2 or C3 at the branch after process B when returning the display to the downstream side of process C1 after displaying the upstream side of process B, the user may view the route of the manufacturing process of another product 16.

[0074] If the manufacturing process of other products 16 is displayed, not only will the user be unable to view the manufacturing process of the product 16 that he or she originally wanted to view, but there is also the possibility that the user will unnecessarily view the manufacturing process of other companies' products 16. For this reason, viewing such manufacturing processes of other products 16 must be prevented.

[0075] Therefore, in the manufacturing history display system 10 of the present embodiment, a transition history of the 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. Then, the display control unit 32 starts the display with the latest process information, and when transitioning the display from the downstream side of the process to the upstream side and then returning the display to the downstream side of the process, does not cause the display unit 22 to display process information that differs from the transition history.

[0076] 6, when returning the display to the downstream process after displaying the process upstream of process B, the user cannot select display of processes C2 and C3, and only the process downstream of process C1 is displayed. In other words, when returning the display from the upstream process to the downstream process after displaying the upstream process, the mobile terminal device 12 does not display processes different from the display route that reached the upstream process, but displays the same processes as the display route.

[0077] Therefore, the manufacturing history display system 10 of this embodiment can prevent the display of manufacturing processes of a product 16 that is different from the original product 16. Also, by storing the transition history, the user can quickly search for process information to be displayed on the display unit 22.

[0078] Furthermore, the mobile terminal device 12 of the present embodiment allows the user to change the operation method for transitioning the display of process information through settings.

[0079] By changing the settings, for example, upstream process information may be displayed by swiping to the right, and downstream processes may be displayed by swiping to the left. Also, the process information displayed on the display unit 22 may be shifted in the vertical direction by swiping up and down. Also, instead of gesture operations such as swiping, arrow buttons may be displayed and the process information displayed on the display unit 22 may be shifted by operating the arrow buttons. This allows the operation method to be changed depending on the generation and preferences of the user, improving operability for the user.

[0080] 7 is a flowchart showing the flow of a 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 included in the mobile terminal device 12. Note that, by executing this program, a method corresponding to the program is executed.

[0081] First, in step S100, the mobile terminal device 12 captures an image of the attached information 18 of the product 16 with the camera 20, and the reading unit 28 reads the contents of the attached information 18.

[0082] In the next step S102, the process information acquisition control unit 30 acquires the latest process information and the process information of one generation before from the server 14 via the communication unit 24, and stores them in the storage unit .

[0083] In the next step S104, the display control unit 32 causes the display unit 22 to display the latest process information.

[0084] In the next step S106, it is determined whether or not a swipe 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.

[0085] In step S108, the display control unit 32 changes the process information to be displayed on the display unit 22 in response to the swipe operation.

[0086] In the next step S110, the process information acquisition control unit 30 judges whether or not process information of a process preceding or succeeding the process information displayed on the display unit 22 has been acquired, and if the judgment is affirmative, the process proceeds to step S114. On the other hand, if the judgment is negative, the process proceeds to step S112.

[0087] In step S112, the process information acquisition control unit 30 acquires process information of a process preceding or succeeding the process information displayed on the display unit 22 from the server 14, and stores the information in the storage unit .

[0088] In the next step S114, it is determined whether or not an operation to end the display application has been performed, and if the determination is affirmative, the display application is ended, and if the determination is negative, the process returns to step S106.

[0089] In step S116, which is reached if the determination in step S106 is negative, it is determined whether or not any operation other than the swipe operation has been performed, and if the determination is positive, the process proceeds to step S118, whereas if the determination is negative, the process returns to step S106. The other operations include, for example, the selection of a branch, the operation of the return to latest button 52, the operation of the transport route display button 54, and the operation of changing settings.

[0090] In step S118, a process corresponding to another operation is carried out, and the process returns to step S106.

[0091] Although the present disclosure has been described above using the above-mentioned embodiment, the technical scope of the present disclosure is not limited to the scope described in the above-mentioned embodiment. Various modifications or improvements can be made to the above-mentioned embodiment without departing from the gist of the disclosure, and the form with the modifications or improvements is also included in the technical scope of the present disclosure.

[0092] For example, in the above embodiment, the display unit 22 displays one piece of process information at a time, but the present invention is not limited to this, and the display unit 22 may display two or more pieces of process information at the same time. Even in this embodiment, the mobile terminal device 12 has the same functions as the above embodiment. For example, 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. In addition, when transitioning the display from the downstream side of the process to the upstream side and then returning the display to the downstream side of the process, the display control unit 32 does not cause the display unit 22 to display process information that is different from the transition history.
