[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on Japanese Patent Application No. 2022-84682 filed on May 24, 2022, and the contents thereof are cited herein. Technical Field

[0003] The present disclosure relates to an information processing device, a manufacturing history display system, a manufacturing history display method, and a manufacturing history display program. Background Art

[0004] In recent years, there has been a demand for management of the manufacturing process of products, management of the amount of carbon dioxide emissions when manufacturing products, etc. Therefore, it is required to understand the manufacturing process for products.

[0005] Patent Document 1 describes a supply chain management method that is implemented by a computer and manages transaction records between traders in a supply chain that includes a plurality of traders.

[0006] Patent Document 1 states that, taking the logistics path of bread as an example, (1) the seed producer delivers wheat seeds to wheat farmers, (2) the wheat farmers deliver wheat grown from the seeds to flour manufacturers, (3) the flour manufacturers deliver flour made from processed wheat to bread manufacturers, (4) the bread manufacturers deliver bread made from flour to convenience stores, and (5) the convenience stores sell the purchased bread to consumers. In the management method of Patent Document 1, consumers can view transaction records such as raw materials, processing steps, and distribution steps by reading the QR code (registered trademark) attached to the purchased bread.

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

[0008] Patent Document 1 gives an example with relatively few steps, but in a reusable product, steps such as manufacturing, shipping, and recycling of the product are repeated. In addition, if the number of steps increases, the supply chain also increases and becomes more complicated.

[0009] Furthermore, considering that multiple supply chains are involved in manufacturing a product, it is not preferable that anyone can confirm the manufacturing process of the product by reading the QR code attached to the product. Summary of the invention

[0010] 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 restrict browsing of processes related to manufacturing of a product.

[0011] The present disclosure adopts the following technical means to solve the above-mentioned problems. The reference numerals in parentheses in the claims are examples of the correspondence relationship with specific elements described in the embodiments described later as one mode, and do not limit the technical scope of the present disclosure.

[0012] An information processing device according to one embodiment of the present invention comprises: a reading unit, which reads supplementary information associated with the 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 specifies the above-mentioned process information that can be displayed on the above-mentioned display unit for each of the above-mentioned supplementary information.

[0013] 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. The manufacturing history information is information that records multiple process information representing processes related to the manufacturing of the product in a time series. The process information is, for example, information related to various processes such as the procurement of raw materials in a product, the processing of parts from raw materials, the assembly of products from parts, the transportation of raw materials and parts, and the inspection of parts and products. In addition, when recycled materials are used as raw materials, the recycling process is also included in the manufacturing history.

[0014] Here, the manufacturing of products often involves multiple supply chains. Therefore, in view of the fact that multiple supply chains are involved in manufacturing products, it is not preferable that anyone can confirm the manufacturing process of the product by reading the attached information attached to the product.

[0015] Therefore, according to this structure, process information that can be displayed on the display unit is specified for each auxiliary information. Thus, the user can view the process information only within the range specified by the auxiliary information. Therefore, this structure can limit the viewing of processes related to the manufacture of the product.

[0016] In the above-mentioned information processing device, the above-mentioned attached information may also be specified as follows: the above-mentioned process information of the attached product and the above-mentioned process information on the upstream side of the attached product can be displayed, and the above-mentioned process information on the downstream side of the attached product cannot be displayed. According to this structure, for example, the manufacturing process on the upstream side of the product manufactured by the company can be browsed, while on the other hand, the manufacturing process of other companies that use the company's products, that is, the manufacturing process on the downstream side cannot be browsed.

[0017] In the above-mentioned information processing device, the process information which is set to be non-displayable can also be displayed by inputting a predetermined password. According to this structure, for example, the reading restriction can be lifted for a person with special authority such as a supervisor of all processes or an administrative supervisor.

[0018] In the above-mentioned information processing device, the above-mentioned manufacturing history information may also include processes related to the reuse of the above-mentioned product. When the processes of returning raw materials caused by the above-mentioned reuse, manufacturing of the above-mentioned product and reuse of the above-mentioned product are repeatedly recorded, the latest return of raw materials caused by reuse will be used as the upstream process that can be displayed by the above-mentioned display unit.

[0019] According to this configuration, even if the manufacturing process and recycling process of a product are repeated multiple times, the user can easily understand the manufacturing process and recycling process of the product because the latest return of raw materials due to recycling is listed as the most upstream process that can be browsed.

[0020] In the above-mentioned information processing device, the above-mentioned auxiliary information may also be raw material information, or manufacturing information, or carbon footprint, or due diligence, or transaction history of carbon dioxide emissions, or carbon tax payment history, or carbon border adjustment processing payment history information, or their hash values, or hash values ​​calculated according to the Merkle root.

[0021] The attached information includes carbon emissions, carbon dioxide emissions trading, carbon tax payment history, carbon border adjustment payment history, etc. In addition, the timing of carbon emissions and various emission rights offsetting each other, that is, carbon neutrality, can be used as the most upstream process that can be displayed by the display unit. In this way, it is possible to prevent double payment of various taxes related to carbon dioxide emissions and improper increase of carbon emissions of materials reused multiple times, and promote the use of recycled materials.

[0022] A manufacturing history display system of one embodiment of the present invention comprises: a server storing manufacturing history information, wherein the manufacturing history information records a plurality of process information representing processes related to the manufacturing of a product in a time series; and an information processing device, which obtains the manufacturing history information associated with the additional information from the server by reading additional information associated with the manufacturing history information and attached to the product, and displays the history information on a display unit, and specifies the process information that can be displayed on the display unit for each additional information.

[0023] 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 for each of the above-mentioned supplementary information, the above-mentioned process information that can be displayed on the above-mentioned display unit is specified.

[0024] A manufacturing history display program of one method disclosed in the present invention enables a computer included in an information processing device to function as the following structure: 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 above-mentioned reading unit from a server; and a display control unit, which displays the above-mentioned manufacturing history information acquired by the above-mentioned acquisition control unit 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 specifies the above-mentioned process information that can be displayed on the above-mentioned display unit for each of the above-mentioned supplementary information.

[0025] According to the present disclosure, it is possible to restrict browsing of processes related to the manufacture of a product. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Hereinafter, the embodiments of the present disclosure will be described with reference to the accompanying drawings. In addition, the embodiments described below represent an example of implementing the present disclosure, and the present disclosure is not limited to the specific structures described below. When implementing the present disclosure, a specific structure corresponding to the embodiments can be appropriately adopted.

[0035] 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 .

[0036] The mobile terminal device 12 is provided with a camera 20 (see Figure 6 ) and a smartphone, tablet terminal or other information processing device 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 is capable of reading the additional information 18 (as an example, a QR code) of the product 16 described later and displaying the process information, it may be a dedicated device for displaying the process information, or a reading device assembled in an existing manufacturing device for manufacturing the product 16 may be used.

[0037] The mobile terminal device 12 uses the camera 20 to capture the attached information 18 attached to the product 16 and reads the recorded content of the attached information 18 .

[0038] The attached information 18 is an information code associated with the manufacturing history information of the product 16 and attached to the product 16. As an example, the attached information 18 of this embodiment is a QR code, but it is not limited to this, and it can also be an information code such as other two-dimensional codes, bar codes, etc. One-dimensional codes. The attached information 18 records at least the query destination of the manufacturing history information of the attached product 16 (IP address, URL, etc. of the server 14). In addition, the manufacturing history information is also information for tracking the process from the manufacture to the consumption of the product 16, and in the following description, it is called traceability information.

[0039] 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 is a raw material, a component manufactured by processing the raw material, a final product composed of multiple components, etc., and there are various methods in its manufacturing process.

[0040] In addition, for example, in the procurement process of raw materials and the processing process of parts, there are branches that include the manufacturing process of other products 16. The other products 16 mentioned here refer not only to the company's products 16, but also to other companies' products 16. In addition, the traceability information may also include a series of processes from the used product 16 being collected and reused to manufacturing the product 16 using the recycled materials.

[0041] In the server 14, data related to the manufacturing process of each product 16 is accumulated by sequentially adding it to the traceability information as process information in time series. Each process information includes information such as the content of the process, the registration date and 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.

[0042] In addition, each process information includes information such as when and where the process is performed, and the amount of carbon dioxide (CO2) emitted in the process. In addition, the amount of carbon dioxide emitted includes not only the process directly related to manufacturing, but also the amount of carbon dioxide emitted by transportation equipment such as ships and trucks through the transportation of the product 16. In this way, a carbon footprint based on traceability information is realized.

[0043] In the management of traceability information of the present embodiment, as an example, blockchain technology is used to prevent tampering of traceability information. Specifically, for example, the server 14 generates a hash value of data associated with each process of the product 16, and uses these data (hash value) as a block to perform embedding processing connected to the last block of the blockchain. In addition, the server 14 repeatedly calculates the hash value reflecting the previous manufacturing process as the manufacturing process of the product 16 proceeds. As a result, the hash value provided by each manufacturing process of the product 16 becomes a value (Merkle root) reflecting all previous manufacturing processes. As a result, the traceability information becomes a state of being saved using the blockchain in a manner associated with the process information of the product 16. In addition, the server 14 of the present embodiment generates the 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 manner that can be attached to the product 16.

[0044] A QR code as the attached information 18 is attached to each product 16 in each process. In addition to being attached directly to the product 16, the attached information 18 may also be attached to a container storing the product 16, a label for managing the product 16, etc. The attached information 18 is newly generated by the server 14 in each predetermined process, for example. In this case, the manufacturer (supply chain) of the product 16 that newly generates the attached information 18 outputs the QR code to a paper medium or the like, and attaches it to each product 16.

[0045] The mobile terminal device 12 captures 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 recorded content (query destination) obtained by reading the attached information 18. The mobile terminal device 12 displays the traceability information obtained from the server 14 on the display unit 22.

[0046] Figure 2 This is a diagram showing the display method of the process information of the mobile terminal device 12 of the present embodiment. In addition, when the mobile terminal device 12 reads the attached information 18 and obtains the process information from the server 14, the application (hereinafter referred to as the "display application") pre-installed in the mobile terminal device 12 is started, and the obtained process information is displayed on the display unit 22.

[0047] like Figure 2 As shown, the mobile terminal device 12 of the present embodiment displays each process information included in the traceability information on the display unit 22, and the process information displayed on the display unit 22 is shifted in time series according to the user's operation.

[0048] Figure 2 (A) is a diagram showing process information initially displayed on the display unit 22 by reading the attached information 18. Figure 2 The display unit 22 shown in (A) slides to the right, as shown in FIG. Figure 2 (B) Figure 2 (A) The previous process information.

[0049] In this way, the mobile terminal device 12 of this embodiment makes the process information displayed on the display unit 22 migrate 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, in this embodiment, the process information displayed on the display unit 22 is migrated by sliding the display unit 22, but it is not limited to this. For example, an arrow button for migrating the display of the process may be displayed on the display unit 22, and the displayed process information is migrated by clicking the arrow button.

[0050] The mobile terminal device 12 of this embodiment uses the latest process information as the start time of display, and displays the degree of separation between the process information displayed on the display unit 22 and the latest process information on the display unit 22, so that the user can easily understand the process displayed on the display unit 22.

[0051] The degree of separation is Figure 2 The generation display column 24 in the display is displayed as “generation”. Figure 2 (A) shows the latest process information, so “latest” in the generation display column 24 is highlighted. Figure 2 (B) is the process information of the previous generation, so the "previous generation (1)" in the generation display column 24 is highlighted. Figure 2 In the display state of (B), if the user slides to the right, the process information of the previous two generations is displayed on the display unit 22, and "previous two generations (1)" in the generation display column 24 is highlighted.

[0052] And, if Figure 2 As shown in (B), the mobile terminal device 12 displays an operation image (hereinafter referred to as a "return to latest button") 52 for returning the display of the display unit 22 to the latest process information on the display unit 22. Thus, even if the process information on the upstream side is displayed, by operating (clicking) the return to latest button 26, the latest process information is displayed on the display unit 22, so that the user can easily understand the process and the operability is improved. In addition, when the latest process information is displayed on the display unit 22, the return to latest button 26 is not displayed. In addition, as described later, when the latest process information cannot be displayed due to viewing restrictions, if the return to latest button 26 is operated, the mobile terminal device 12 displays the process information that is closest to the latest among the process information that can be displayed on the display unit 22.

[0053] In addition, the display unit 22 displays "Packaging Manufacturing" or "Material Manufacturing" as the names of the displayed process information, the registration date and time of the detailed process information to the traceability information, the product name of the product 16, the name of the company that manufactured the product 16, the base name as the manufacturing site, the latitude and longitude of the location of the base, etc.

[0054] 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 previous process (cumulative value) is displayed on the display unit 22. Thus, a carbon footprint is realized, and the user can understand the amount of carbon dioxide emitted in the manufacturing process.

[0055] Furthermore, in the mobile terminal device 12 of the present embodiment, information that is not 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.

[0056] In this way, the mobile terminal device 12 of this embodiment displays each process information included in the traceability information on the display unit 22 , but the present invention is not limited thereto. The mobile terminal device 12 may display a plurality of process information at once on the display unit 22 .

[0057] Figure 3 It is a schematic diagram showing the manufacturing process of product 16. 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. In order to manufacture product 16, including the supply chain, various processes are required, such as the procurement of various raw materials, processing to parts, processing from raw materials to parts, assembly from parts to final products, transportation of raw materials and parts, and inspection of parts and final products. In addition, there are various methods such as adding processes, integrating processes, and branching processes. In addition, the so-called integration of processes is a method of treating multiple front processes as one back process. The so-called branching of processes is a method of treating one front process as multiple back processes.

[0058] exist Figure 3 The recycling process of recycling the final product and using it again as a raw material (recycled material) is included. That is, as an example, Figure 3 The black dots in the figure represent the manufacturing process of the product 16, the white dots represent the final product, and the circles shaded with oblique lines represent the recycling process. Figure 3 In the example of , the final product is manufactured not only using recycled materials but also using virgin materials as new raw materials. The final product can also be manufactured using only recycled materials.

[0059] like Figure 3 As shown, the manufacturing process of the product 16 including the recycling process repeats the manufacturing and recycling of the final product. In addition, the number of processes increases, and the supply chain also increases, making it more complicated. In addition, considering that multiple supply chains are involved in manufacturing the product 16, it is not preferable that anyone can confirm the manufacturing process of the product 16 by reading the attached information 18 attached to the product 16.

[0060] Therefore, in this embodiment, the process information that can be displayed on the display unit 22 is specified for each of the attached information 18. Thus, the user can browse the process information only within the range specified by the attached information 18. Therefore, the manufacturing history display system 10 of this embodiment can limit the browsing of the process related to the manufacturing of the product 16.

[0061] Reference Figure 4 , Figure 5 , the auxiliary information 18 and the process information that can be displayed are explained. Figure 4 1 is a schematic diagram showing the relationship between the additional information 18 attached to the product 16 and the process. Figure 4In the example, processes A to C, process D, process E to G, process H to J, process K to M, and process N to O are processes implemented by different supply chains. In addition, the product 16 in processes A to C is attached with attached information 18a. The attached information 18a is attached to the product 16 in process A.

[0062] Similarly, the product 16 in process D is attached with attached information 18d. The attached information 18d is attached to the product 16 in process D. The product 16 in processes E to G is attached with attached information 18e. The attached information 18e is attached to the product 16 in process E. The product 16 in processes H to J is attached with attached information 18h. The attached information 18h is attached to the product 16 in process H. The product 16 in processes K to M is attached with attached information 18k. The attached information 18k is attached to the product 16 in process K. The product 16 in processes N to O is attached with attached information 18n. The attached information 18n is attached to the product 16 in process N.

[0063] The attached information 18 of this embodiment is defined as being able to display process information of the attached product 16 and process information on the upstream side of the attached product, but not being able to display process information on the downstream side of the attached product 16. Thus, the manufacturing history display system 10 of this embodiment, for example, can browse the manufacturing process on the upstream side of the product 16 manufactured by the company, but on the other hand, cannot browse the manufacturing process of other companies that use the company's product 16, that is, the manufacturing process on the downstream side.

[0064] In addition, the attached information 18 is affixed to the product 16 each time the readable process changes. Figure 4 In the example, in process A, additional information 18a is pasted on product 16, and in process D it is re-pasted as additional information 18d. Similarly, in process E it is re-pasted as additional information 18e, in process H it is re-pasted as additional information 18h, in process K it is re-pasted as additional information 18k, and in process N it is re-pasted as additional information 18n.

[0065] Figure 5 is a schematic diagram showing a browsable manufacturing process associated with the attached information 18. Figure 4 The process shaded in black is the current process, the process shaded by diagonal lines is the process on the downstream side of the current process, and the process shaded by cross-hatching is the process on the upstream side of the current process.

[0066] That is, in Figure 4 , Figure 5In the example of , when the mobile terminal device 12 reads the additional information 18a, although the process information of processes A to C can be displayed, the process information on the downstream side of processes A to C cannot be displayed. In addition, when the mobile terminal device 12 reads the additional information 18d, although the process information of processes A to C can be displayed together with the process information of process D, the process information on the downstream side of process D cannot be displayed. When the mobile terminal device 12 reads the additional information 18e, although the process information of processes A to D can be displayed together with the process information of processes E to G, the process information on the downstream side of processes E to G cannot be displayed. When the mobile terminal device 12 reads the additional information 18h, although the process information of processes A to D can be displayed together with the process information of processes H to J, the process information on the downstream side of processes H to J cannot be displayed. When the mobile terminal device 12 reads the additional information 18k, although the process information of processes A to D can be displayed together with the process information of processes K to M, the process information on the downstream side of processes K to M cannot be displayed. When the mobile terminal device 12 reads the attached information 18n, the process information of the processes A to M, that is, all the process information can be displayed together with the process information of the processes N to O.

[0067] Here, a method for generating supplementary information 18 in which reading restrictions are specified in process information is described. The supplementary information 18 of this embodiment calculates the Merkle root of each process, and records the front and back relationship of the Merkle root of each process in the server 14. In each process, the Merkle root is recorded in the supplementary information 18. In the case where the supplementary information 18 attached to the product 16 is read by the mobile terminal device 12, the search is performed only on the upstream process side from the server 14. In addition, when the search reaches the most upstream process, the search before it is not performed, and the search results of the searched information are displayed on the display unit 22 of the mobile terminal device 12. However, by entering a specified password, it is possible to perform a search after reaching the most upstream process and a search on the downstream process side. As a result, it is possible for supervisors of all processes, administrative supervisors, and other people with special authority to view necessary information.

[0068] Furthermore, the supplementary information 18 may be information such as raw material information, manufacturing information, carbon footprint, due diligence, transaction history of carbon dioxide emissions, carbon tax payment history, carbon border adjustment payment history, etc., or hash values ​​thereof, or hash values ​​calculated based on Merkle roots. That is, the QR code as the supplementary information 18 is generated by converting the hash value.

[0069] In this way, the attached information includes carbon emissions, carbon dioxide emissions transactions, carbon tax payment history, carbon border adjustment payment history, etc. In addition, in this embodiment, the timing at which carbon emissions and various emission rights offset each other, that is, carbon neutrality, can also be used as the most upstream process that can be displayed by the display unit 22. In this way, it is possible to prevent double payment of various taxes related to carbon dioxide emissions and inappropriate increase of carbon emissions of materials that are reused many times, and promote the use of reused materials.

[0070] In addition, in the mobile terminal device 12 of this embodiment, process information that cannot be displayed can be displayed by inputting a predetermined password. The password is input by the user through the display application, for example, and is sent to the server 14 and authenticated by the server 14. Thus, for example, the reading restriction can be lifted for people with special authority such as supervisors of all processes and administrative supervisors.

[0071] Figure 6 This is a functional block diagram related to the display of traceability information by the manufacturing history display system 10 .

[0072] The mobile terminal device 12 includes a communication unit 30 , a storage unit 32 , a reading unit 34 , a process information acquisition control unit 36 ​​, a display control unit 38 , and a password reception unit 40 together with the camera 20 and the display unit 22 .

[0073] The camera 20 has a photographing function, and in the present embodiment, photographs the attached information 18 attached to the product 16 .

[0074] The display unit 22 is, for example, a touch panel display, and displays various data or receives user operations on the mobile terminal device 12 .

[0075] The communication unit 30 transmits and receives information to and from other information processing devices such as the server 14. In addition, the communication unit 30 of this embodiment transmits and receives information to and from the server 14 via the communication unit 50 provided in the server 14. The storage device 52 provided in the server 14 stores traceability information of the product 16.

[0076] The storage unit 32 stores various data such as a program (application) related to reading of the attached information 18 and display of process information, and process information acquired from the server 14 .

[0077] The reading unit 34 reads the attached information 18 (QR code) captured by the camera 20 . The reading unit 34 performs a decoding process for deciphering information recorded in the read attached information 18 .

[0078] The process information acquisition control unit 36 ​​acquires the traceability information associated with the attached information 18 read by the reading unit 34 from the server 14 via the communication unit 30. In addition, the process information acquisition control unit 36 ​​of the present embodiment does not acquire all traceability information from the server 14 at once, but sequentially acquires 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 32.

[0079] In addition, when acquiring the traceability information, the process information acquisition control unit 36 ​​transmits information indicating the displayable range of the process information specified in the attached information 18 (hereinafter referred to as "displayable range information") to the server 14 via the communication unit 30. The displayable range information is obtained by reading the attached information 18 using the reading unit 34. That is, the process information not included in the displayable range information is the process information that is subject to the viewing restriction.

[0080] The display control unit 38 controls the display unit 22 to display various images. The display control unit 38 of the present embodiment causes the display unit 22 to display the traceability information acquired by the process information acquisition control unit 36 ​​.

[0081] The password accepting unit 40 accepts input of a password for allowing display of process information that cannot be displayed, via the display unit 22. The password accepting unit 40 transmits the input password to the server 14 via the communication unit 30.

[0082] The server 14 includes a displayable range determination unit 54 and a browsing restriction removal unit 56 together with the communication unit 50 and the storage device 52 .

[0083] The displayable range determination unit 54 determines the range of process information displayable on the mobile terminal device 12 that has transmitted the displayable range information, based on the displayable range information received from the mobile terminal device 12 via the communication unit 50 .

[0084] The browsing restriction removal unit 56 authenticates the password received from the mobile terminal device 12 via the communication unit 50 , and when the authentication is successful, all the process information can be displayed on the mobile terminal device 12 that has transmitted the password.

[0085] Figure 7 This is a flowchart showing the flow of the manufacturing history display process executed in the manufacturing history display system 10. The manufacturing history display process is started by activating a program (display application) stored in a recording medium such as the storage unit 32 provided in the mobile terminal device 12. In addition, by executing the program, a method corresponding to the program is executed.

[0086] First, in step S100 , the mobile terminal device 12 captures the attached information 18 of the product 16 using the camera 20 and reads the content of the attached information 18 .

[0087] In the next step S102 , the process information acquisition control unit 36 ​​transmits the displayable range information obtained by reading the attached information 18 to the server 14 via the communication unit 30 .

[0088] In the next step S104 , the displayable range determination unit 54 of the server 14 determines the process information displayable on the mobile terminal device 12 that has transmitted the displayable range information, based on the displayable range information received via the communication unit 50 .

[0089] In the next step S106, the process information acquisition control unit 36 ​​determines whether a password has been input, and if the determination is affirmative, the password is transmitted to the server 14 and the process proceeds to step S108. On the other hand, if the determination is negative, the process proceeds to step S110.

[0090] In step S108 , the browsing restriction removal unit 56 of the server 14 performs password authentication, and when the authentication is successful, removes the browsing restriction, and the process proceeds to step S110 .

[0091] In step S110 , the process information acquisition control unit 36 ​​acquires process information from the server 14 via the communication unit 30 .

[0092] In the next step S112, the display control unit 38 displays the process information on the display unit 22. When the process information displayed on the display unit 22 is changed by the user operating the display unit 22, the process information acquisition control unit 36 ​​sequentially acquires the process information from the server 14. At this time, when the user wants the process information displayed on the display unit 22 to be the object of viewing restriction, an image indicating that the process information is the object of viewing restriction is displayed on the display unit 22.

[0093] In addition, the traceability information of this embodiment includes the process related to the reuse of the product 16, and the process of returning the raw materials based on the reuse, manufacturing the product 16, and reusing the product 16 is repeatedly recorded multiple times. In the case of such traceability information, the repetition of the manufacturing process and the reuse process of the product 16 can also be displayed without restriction, but if it is set as unlimited, there is a high possibility that it exceeds the user's understanding.

[0094] Therefore, the manufacturing history display system 10 of this embodiment uses the latest return of raw materials due to reuse as the most upstream process that can be displayed by the display unit 22. That is, the process that can be displayed is only a combination of a one-time manufacturing process and a reuse process. Figure 3For example, located Figure 3 The procurement process of recycled materials and virgin materials on the left is the most upstream process that can be displayed, and the processes including the recycling process before this are not displayed.

[0095] Therefore, even if the manufacturing process and recycling process of the product 16 are repeated multiple times, the user can easily understand the manufacturing process and recycling process of the product 16 because the latest return of raw materials due to recycling is listed as the most upstream process that can be browsed.

[0096] In addition, as an example, the total amount of carbon dioxide emitted in each process displayed on the display unit 22 is reset at the time of purchasing the raw material of the recycled material or the virgin material, and is used as a cumulative value in the subsequent process.

[0097] 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.

[0098] 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 within the scope of the disclosure, and the methods obtained by applying the changes or improvements are also included in the technical scope of the present disclosure.
