  The control unit 30 includes a CPU 32 and a memory 34. The CPU 32 executes various processes according to the program stored in the memory 34. The functions of the respective units 41 to 49 are realized by the CPU 32 executing processes according to the above programs. The memory 34 stores a plurality of user information in addition to the above programs. In FIG. 1, the service table is stored in the memory 34, but the service table is used in a fourth embodiment described later.

  Each of the plurality of user information is user information that can receive a service from each of the service providing servers 100 and 110 described later. Each user information is information in which a display name, a service name, and an access token (hereinafter referred to as “AT”) are associated with each other. Hereinafter, the display name and the service name are collectively referred to as “account information”. Therefore, each user information is information in which account information (that is, display name and service name) and AT are associated with each other.

  The display name is a name for display of the user on the multi-function device 10. The service name is the name of a service providing server (for example, 100) from which the user can receive the service. The AT is authentication information given from a service providing server (for example, 100), and is used for authentication in the service providing server. The manner in which each piece of user information is stored in the memory 34 will be described later.

(Configuration of Mediation Server 50)
The mediation server 50 is a server provided by the vendor of the MFP 10, and is a server for mediating provision of services from the service providing servers 100 and 110 to the MFP 10.

The memory 74 stores a later-described service table (see FIG. 3) in addition to the above programs. In FIG. 1, the server table is stored in the memory 74, but the server table is used in a second embodiment described later.

(Configuration of service providing servers 100 and 110)
The service providing servers 100 and 110 are known service providing servers such as “Evernote (registered trademark)”, “Google (registered trademark) Docs”, “PICASA (registered trademark)”, “Facebook (registered trademark)”, and the like. It is. In the present embodiment, the names (namely, service names) of the service providing servers 100 and 110 are “AAA” and “BBB”, respectively. Each service providing server 100, 110 can execute a data storage service that acquires and stores data from a communication device (for example, the mobile terminal 150, the MFP 10). In addition, each service providing server 100, 110 can execute a data providing service that provides data to a communication device.

The service providing server 100 is a server provided by a first service provider (that is, a first company), and the service providing server 110 is a second service provider (that is, different from the first service provider). Server provided by a second company). The first service provider publishes a first API (abbreviation of Application Program Interface) for receiving services from the service providing server 100, and the second service provider provides services from the service providing server 110. A second API is available for receiving. Since the first service provider and the second service provider are different, the first API and the second API are usually different. For example, the communication device includes both a first API (that is, the first program) and a second API (that is, the second program) in order to receive services from both the service providing servers 100 and 110. Must be.

  For example, in order for the MFP 10 to receive a service from each of the plurality of service providing servers 100 and 110, the MFP 10 must have a plurality of APIs, and thus must store a large number of programs. However, compared with a PC or the like, the storage capacity of the memory 34 of the MFP 10 is small. Therefore, in this embodiment, the mediation server 50 is provided so that the MFP 10 can receive services from each of the plurality of service providing servers 100 and 110 without storing many programs in the MFP 10.

  The mediation server 50 includes a plurality of APIs corresponding to the plurality of service providing servers 100 and 110. The mediation server 50 uses the APIs corresponding to the service providing servers 100 and 110 so that the MFP 10 can receive services from the service providing servers 100 and 110. And various communications (for example, communications such as a command 206 in FIG. 3 described later). Thus, even if the MFP 10 does not have APIs corresponding to the service providing servers 100 and 110 (that is, does not store many programs), the MFP 10 receives services from the service providing servers 100 and 110. Can do. Further, when the specifications of the service providing servers 100 and 110 are changed, if the program of the mediation server 50 is changed, the specification change can be dealt with without changing the program of the MFP 10. Further, if the program of the mediation server 50 is changed so that an API corresponding to the new service providing server is provided, the MFP 10 can receive a service from the new service providing server without changing the program of the MFP 10. it can.

(Configuration of mobile terminal 150)
The mobile terminal 150 is a portable terminal device such as a mobile phone (for example, a smartphone), a PDA, a notebook PC, a tablet PC, a portable music playback device, a portable video playback device, and the like. Although not shown, the mobile terminal 150 includes an interface for executing NFC communication and an interface for executing wireless communication based on a wireless communication standard defined by the Wi-Fi Alliance. In the following, the latter wireless communication is referred to as “Wi
This is called “Fi communication”. The portable terminal 150 can connect to the Internet by executing Wi-Fi communication. In this embodiment, it is assumed that the portable terminal 150 and the MFP 10 are not connected to the same LAN.

Here, the difference between NFC communication and Wi-Fi communication is described. As described above, NFC communication is wireless communication based on, for example, ISO / IEC21481 or 18092 international standards. On the other hand, Wi-Fi communication is, for example, IEEE (abbreviation of The Institute of Electrical and Electronics Engineers, Inc.) 802.11 standard, and
The wireless communication is based on a standard (for example, 802.11a, 11b, 11g, 11n, etc.) according to the standard. The communication speed of NFC communication (for example, maximum communication speed = 100 to 424 Kbps) is slower than the communication speed of Wi-Fi communication (for example, maximum communication speed = 11 to 600 Mbps). Further, the frequency of a carrier wave (for example, 13.56 MHz band) in NFC communication is different from the frequency of a carrier wave (for example, 2.4 GHz band or 5.0 GHz band) in Wi-Fi communication. Moreover, the communicable distance (for example, 10 cm or less) of NFC communication is shorter than the communicable distance (for example, 100 m or less) of Wi-Fi communication.

The portable terminal 150 includes a known OS program (for example, Android (registered trademark)) that supports NFC communication and Wi-Fi communication. The portable terminal 150 further includes a known web browser program. The mobile terminal 150 further includes first and second APIs corresponding to the service providing servers 100 and 110. However, the mobile terminal 150 does not include a special application program (for example, a printer driver program or a scanner driver program) that causes the MFP 10 to execute a function (for example, a print function or a scan function).

(Preparation by user)
The user performs the following preparations in order for the MFP 10 to receive services from the service providing servers 100 and 110. For example, the user accesses the mediation server 50 using a PC (not shown), selects the service name “AAA” of the service providing server 100, and then selects “Acquire AT”. In this case, the control unit 70 of the mediation server 50 transmits a specific URL (abbreviation for Uniform Resource Locator) for accessing the service providing server 100 to the PC. The user accesses the service providing server 100 from the PC using a specific URL. As a result, the PC displays a login screen for logging in to the service providing server 100.

  Next, the user inputs an account name and a password via the PC and executes an authentication procedure. When the authentication is successful, the service providing server 100 generates an AT for the user and transmits the AT to the mediation server 50. When receiving the AT from the service providing server 100, the control unit 70 of the mediation server 50 generates a temporary ID and transmits the temporary ID to the PC. The PC displays the temporary ID. Thereby, the user can know the temporary ID displayed on the PC.

  Next, the user operates the operation unit 12 of the MFP 10 to select the service name “AAA” of the service providing server 100 and further inputs a desired display name (for example, “Alice”) to the MFP 10. The user further operates the operation unit 12 of the MFP 10 to input the temporary ID displayed on the PC to the MFP 10. In this case, the control unit 30 of the MFP 10 transmits a temporary ID to the mediation server 50. As a result, the control unit 70 of the mediation server 50 transmits the AT to the MFP 10.

When the above processes are executed, the control unit 30 of the MFP 10 can add one piece of user information to the memory 34. That is, the control unit 30 of the MFP 10 associates the display name (for example, “Alice”) input by the user, the service name “AAA” selected by the user, and the AT received from the mediation server 50. One piece of user information can be stored in the memory 34.

Similarly to the above, the control unit 30 of the MFP 10 can cause the memory 34 to store user information corresponding to the service providing server 110 having the service name “BBB”. In this embodiment, it is assumed that the MFP 10 is shared by a plurality of users. Accordingly, the control unit 30 of the MFP 10 can store a plurality of pieces of user information corresponding to a plurality of users in the memory 34. As a result, for example, as shown in FIG. 4, the memory 34 can store a plurality of pieces of user information (four pieces of user information No. 1 to No. 4 in the example of FIG. 4).

(Each process executed by each device)
Next, the contents of each process executed by each device 10, 50, 100, 150 will be described. Hereinafter, the user of the mobile terminal 150 is referred to as a “target user”. The target user uses, for example, the portable terminal 150 to log in to the service providing server 100 such as “Facebook (registered trademark)” and downloads the resource image file (for example, the resource image included in the lower diagram in FIG. 2). The resource image file) is uploaded to the service providing server 100 in advance. As described above, since the mobile terminal 150 includes the first API corresponding to the service providing server 100, the uploading can be executed according to the first API. The resource image file is, for example, a file having a format such as JPEG (abbreviation of Joint Photographic Experts Group) or PDF (abbreviation of Portable Document Format).

  The service providing server 100 not only saves the resource image file uploaded from the mobile terminal 150 but also uses a thumbnail image file (for example, a file representing a thumbnail image included in the upper diagram in FIG. 2) based on the resource image file. ) And save the thumbnail image file.

  When the resource image file and the thumbnail image file are stored in the service providing server 100, the target user uses the portable terminal 150 to display a thumbnail page including the thumbnail image represented by the thumbnail image file (the upper diagram in FIG. 2). And a resource page (see the web page shown in the lower diagram in FIG. 2) including the resource image represented by the resource image file. Specifically, the target user first logs in to the service providing server 100 by adding an operation for starting the web browser to the mobile terminal 150. Next, the target user carries an operation for browsing the thumbnail page (for example, an operation for selecting a predetermined album from a list of albums, an operation for selecting a predetermined thumbnail image from a list of thumbnail images included in the album, etc.). Add to terminal 150. In this case, as shown in FIG. 3, the web browser transmits a thumbnail request command 200 of HTTP (abbreviation of Hyper Text Transfer Protocol) to the service providing server 100 using Wi-Fi communication. The thumbnail request command 200 includes a URL 100a as a request destination URL. URL 100a indicates the position of thumbnail data 202 representing a thumbnail page. The thumbnail data 202 is HTML (abbreviation of Hyper Text Markup Language) format data representing a thumbnail page.

  When the service providing server 100 receives the thumbnail request command 200 from the mobile terminal 150, the service providing server 100 transmits the thumbnail data 202 to the mobile terminal 150 in accordance with the request destination URL 100 a included in the thumbnail request command 200.

The web browser of the portable terminal 150 uses the Wi-Fi communication to display the thumbnail data 20
2 is received. Thereby, the web browser can display the thumbnail page represented by the thumbnail data 202 on the display (not shown) of the mobile terminal 150.

The upper diagram in FIG. 2 shows an example of a thumbnail page displayed on the mobile terminal 150. The thumbnail page includes a URL 100a, a thumbnail image (a flower image in FIG. 2), and text indicating various information (for example, a title “photo album”, a comment “flower image”, and the like). The URL 100a includes the server name “www.aa.com” of the service providing server 100. This means that the thumbnail data 202 is provided from the service providing server 100. The character string “xxxxx” included in the URL 100a includes an ID for specifying a thumbnail image file. As is clear from the extension “.html” included in the URL 100a, the thumbnail data 202 is data in HTML format.

  When the target user desires to view a resource image larger than the thumbnail image, the target user performs a predetermined operation (for example, a click operation on the thumbnail image) on the mobile terminal 150 while the thumbnail page is displayed. In this case, although not shown in FIG. 3, the web browser transmits an image request command for requesting the service providing server 100 to transmit the resource image file to the service providing server 100, and the resource is received from the service providing server 100. Receive image files. Thereby, the web browser can display the resource page including the resource image on the display of the mobile terminal 150.

The lower diagram in FIG. 2 shows an example of a resource page displayed on the mobile terminal 150. The resource page includes a resource image file URL 100b and a resource image. The URL 100b includes the server name “www.aa.com” of the service providing server 100. The character string “yyyyy” included in the URL 100b includes an ID for specifying the resource image file. As is clear from the extension “.jpeg” included in the URL 100b,
The resource image file is JPEG format data. As described above, in this embodiment, the data format of the thumbnail data 202 (ie, HTML format) is different from the data format of the resource image file (ie, JPEG format). The resource image represents the same object (ie, flower) as the thumbnail image, but has a larger size than the thumbnail image. That is, the number of pixels of the resource image is larger than the number of pixels of the thumbnail image.

  In a state where the thumbnail page is displayed on the mobile terminal 150, the target user may desire the MFP 10 to print the thumbnail image (that is, the flower image) included in the thumbnail page. In this case, the target user brings the mobile terminal 150 closer to the MFP 10 so that an NFC connection is established between the mobile terminal 150 and the MFP 10. While the MFP 10 is powered on, the NFC I / F 16 of the MFP 10 transmits a detection radio wave for detecting a device capable of performing NFC communication (for example, the portable terminal 150). Further, the NFC I / F (not shown) of the mobile terminal 150 also transmits a detection radio wave for detecting a device (for example, the MFP 10) that can perform NFC communication. When the distance between the MFP 10 and the portable terminal 150 is shorter than the distance (for example, 10 cm) that the detected radio wave reaches, one device of the MFP 10 and the portable terminal 150 receives the detected radio wave from the other device and responds. Send radio waves. As a result, an NFC connection is established between the MFP 10 and the portable terminal 150.

Next, the OS program of the mobile terminal 150 transmits the URL 100a of the thumbnail page currently displayed on the mobile terminal 150 to the MFP 10 using NFC communication (that is, using the NFC connection). Such a mechanism is a mechanism preinstalled in the OS program. That is, when the NFC connection is established and the web browser is operating as the foreground program, the OS program sets the URL of the web page displayed by the web browser (that is, URL 100a in this embodiment) to NFC. It has a mechanism to transmit by communication.

  The receiving unit 41 of the MFP 10 receives the URL 100a using NFC communication (that is, via the NFC I / F 16). In this case, the control unit 30 of the MFP 10 transmits an HTTP URL notification 204 to the mediation server 50 via the network I / F 22. The URL notification 204 includes a URL 100a. The memory 34 stores information for transmitting data to the mediation server 50 (for example, the URL of the mediation server 50) in advance. For this purpose, the control unit 30 can transmit the URL notification 204 to the mediation server 50 using the information.

  As described above, since the MFP 10 does not include the first API, the MFP 10 cannot generate an image request command 206 to be described later using the first API. That is, since the MFP 10 does not include the first API, even if the URL 100a of the thumbnail data 202 is received, the URL 100b of the resource image file cannot be acquired. Therefore, in this embodiment, the MFP 10 transmits a URL notification 204 including the URL 100a to the mediation server 50. As a result, the MFP 10 can acquire the URL 100b of the resource image file via the mediation server 50 even without the first API (the HTTP template 210 in FIG. 3 and the HTTP template 232 in FIG. 4 described later). reference). As a result, the MFP 10 can appropriately acquire the resource image file.

  The receiving unit 81 of the mediation server 50 receives the URL notification 204 including the URL 100 a from the MFP 10. Accordingly, the receiving unit 81 can receive the URL 100a from the portable terminal 150 via the MFP 10.

  Next, the selection unit 82 of the mediation server 50 uses the URL 100 a included in the URL notification 204 to select the service providing server 100 that has transmitted the thumbnail data 202 from the plurality of service providing servers 100 and 110 to the mobile terminal 150. select. Specifically, the selection unit 82 performs the following processing.

The memory 74 of the mediation server 50 stores a service table. In the service table, for each of the plurality of service providing servers 100 and 110, the server name of the service providing server and the service name corresponding to the service providing server are associated with each other. For example, for the service providing server 100, the server name “www.aa.com” and the service name “AAA” are associated with each other.
The server name “www.bb.com” and the service name “BBB” are associated with each other. The service table is stored in advance in the memory 74 of the mediation server 50 by the vendor of the MFP 10 (that is, the administrator of the mediation server 50).

First, the selection unit 82 extracts the character string described before the first slash “/” from the character string after “http: //” included in the URL 100a, thereby obtaining the server name “ www.aa.com ". Then, the selection unit 82 refers to the service table in the memory 74 and sets the service name “AAA” associated with the extracted server name “www.aa.com”.
Is obtained. Accordingly, the selection unit 82 can select the service providing server 100 (that is, the service name “AAA”) from the plurality of service providing servers 100 and 110.

Next, the command communication unit 86 of the mediation server 50 generates an HTTP image request command 206 using the URL 100a and the first API corresponding to the selected service providing server 100. The image request command 206 is a command for requesting the service providing server 100 to transmit the resource image file URL 100b (see the lower diagram in FIG. 2). Specifically, the command communication unit 86 executes the following processing according to the first API (ie, program). That is, the command communication unit 86 extracts the character string “xxxxx” from the URL 100a. As described above, the character string “xxxxx” includes an ID (hereinafter referred to as “specific ID”) for specifying the thumbnail image file. Next, the command communication unit 86 extracts a specific ID in the character string “xxxxx” and generates an image request command 206 including the specific ID. The image request command 206 includes a URL 100a as a request destination URL.

  Among known service providing servers (for example, 100 and 110), there is a server (hereinafter referred to as “corresponding server”) that supports a public command that is a command that does not include an AT (that is, authentication information). There are also servers that do not support public commands (hereinafter referred to as “non-compliant servers”). When the corresponding server receives the public command, it transmits an OK response (for example, a response including the requested information) in response to the request for the public command. On the other hand, when the non-compliant server receives the public command, the non-compliant server transmits an NG response (for example, a response that does not include the requested information).

  Therefore, normally, when communicating with the service providing server, the communication device (for example, the mobile terminal 150) transmits an HTTP command including AT to the service providing server so as not to receive the NG response. For example, the mobile terminal 150 has acquired an AT from the service providing server 100 and transmits a thumbnail request command 200 including the AT to the service providing server 100. For this reason, the mobile terminal 150 can appropriately receive the thumbnail data 202 (that is, an OK response) from the service providing server 100.

  However, the mediation server 50 does not have an AT for receiving services from the service providing server 100. Therefore, in order for the mediation server 50 to transmit the image request command 206 including the AT to the service providing server 100, the mediation server 50 must acquire the AT from the MFP 10. However, for that purpose, communication of various information (for example, communication of each information 220, 222, 224, 226 shown in FIG. 4) must be executed between the mediation server 50 and the MFP 10, and the mediation server The communication load between the MFP 50 and the MFP 10 increases.

  Therefore, in the present embodiment, in view of the possibility that the service providing server 100 is a compatible server that supports public commands, the mediation server 50 first uses a public command that does not include an AT to perform a service. It tries to communicate with the providing server 100. If the service providing server 100 is a compatible server, as described later (refer to the case of YES in S12 to be described later), it is not necessary to perform communication of various information described above between the mediation server 50 and the MFP 10. The mediation server 50 can cause the MFP 10 to print an image (that is, a flower image) included in the thumbnail page.

  The command communication unit 86 generates an image request command 206 that is a public command that does not include an AT. Then, the command communication unit 86 transmits an image request command 206 to the service providing server 100.

When receiving the image request command 206, the service providing server 100 transmits an HTTP response 208 to the mediation server 50. When the service providing server 100 is a compatible server, the service providing server 100 specifies the URL 100b of the resource image file based on the specific ID included in the image request command 206, and a response 208 (including the URL 100b) That is, an OK response) is transmitted to the mediation server 50. On the other hand, when the service providing server 100 is a non-compliant server, the service providing server 1
00 transmits a response 208 (that is, an NG response) that does not include the URL 100 b to the mediation server 50.

  The command communication unit 86 of the mediation server 50 receives the response 208 from the service providing server 100. Next, in S <b> 12, the first determination unit 87 of the mediation server 50 determines whether the service providing server 100 is a compatible server or a non-compatible server based on the response 208. Specifically, if the URL 208 is included in the response 208, the first determination unit 87 determines that the service providing server 100 is a compatible server (that is, YES in S12), and the URL 208 is included in the response 208. If not, it is determined that the service providing server 100 is a non-compliant server (that is, NO in S12).

(Case where the service providing server 100 is a compatible server (YES in S12))
As will be described later, if NO is determined in S12, the display control unit 83 of the mediation server 50 proceeds to FIG. 4 described later, and displays an account selection screen on the display 14 of the MFP 10. On the other hand, if YES is determined in S <b> 12, the display control unit 83 does not display the account selection screen on the display 14 of the MFP 10. Thus, the mediation server 50 can appropriately change whether or not to display the account selection screen according to the determination result of S12.

  If YES is determined in S <b> 12, the specific process execution unit 89 of the mediation server 50 generates the HTTP template 210. The HTTP template 210 is data in which commands and the like related to HTTP are described, and is data for the MFP 10 to generate an image request command 212 described later and transmit the image request command 212 to the service providing server 100.

  Specifically, the specific process execution unit 89 generates the HTTP template 210 so that the request destination URL of the image request command 212 matches the URL 100b (that is, the URL of the resource image file) included in the response 208. That is, the HTTP template 210 includes the URL 100b. The specific process execution unit 89 also generates an HTTP template 210 including a print instruction that instructs the MFP 10 to execute printing. As described above, since it is confirmed that the service providing server 100 is a compatible server (ie, YES in S12), the HTTP template 210 does not include an AT. The specific process execution unit 89 transmits the HTTP template 210 to the MFP 10.

  The control unit 30 of the MFP 10 receives the HTTP template 210 from the mediation server 50. In this case, the control unit 30 interprets the print instruction included in the HTTP template 210 and recognizes that printing should be executed. Then, the control unit 30 generates an HTTP image request command 212 using the HTTP template 210. Specifically, the control unit 30 generates an image request command 212 including the URL 100b included in the HTTP template 210 as a request destination URL. The image request command 212 is an HTTP command that can be generated without using the first API. In other words, the image request command 212 is a command that can be generated by the MFP 10 that does not include the first API. In this respect, the image request command 212 is different from the image request command 206 described above. The control unit 30 transmits an image request command 212 to the service providing server 100.

  When the service providing server 100 receives the image request command 212 from the MFP 10, in accordance with the request destination URL 100 b included in the image request command 212, the service providing server 100 obtains a resource image file 240 (that is, a JPEG file representing the resource image in the lower diagram in FIG. 2). Transmit to the MFP 10.

  The control unit 30 of the MFP 10 receives the resource image file 240 from the service providing server 100. In this case, the control unit 30 converts the resource image file 240 in JPEG format into data having a format that can be interpreted by the print execution unit 18. For example, the control unit 30 converts the resource image file 240 that is RGB multi-gradation (for example, 256 gradation) data into CMYK multi-gradation (for example, 256 gradation) data, and then the CMYK multi-order data. The key data is converted into CMYK binary data (for example, dot ON or OFF). Then, the control unit 30 supplies the CMYK binary data to the print execution unit 18. As a result, the print execution unit 18 prints the resource image (that is, the flower image) represented by the resource image file 240 on the print medium. Thereby, the target user can acquire a printed print medium.

  As described above, in this embodiment, the configuration is such that the mediation server 50 transmits the HTTP template 210 to the MFP 10, and the MFP 10 uses the HTTP template 210 to perform service without using the mediation server 50. The resource image file 240 can be received from the providing server 100. Instead, the configuration in which the mediation server 50 does not transmit the HTTP template 210 to the MFP 10, that is, the configuration in which the mediation server 50 receives the resource image file 240 from the service providing server 100 and transmits the resource image file 240 to the MFP 10. It is also possible to adopt. However, if such a configuration is adopted, the resource image file 240 representing the private image of the target user passes through the mediation server 50, which may cause discomfort to the target user. In view of such a possibility, the present embodiment employs a configuration in which the resource image file 240 does not pass through the mediation server 50, that is, a configuration in which the mediation server 50 transmits the HTTP template 210 to the MFP 10.

(Case where the service providing server 100 is a non-compliant server (NO in S12); FIG. 4)
On the other hand, when NO is determined in S12, the service providing server 100 is a non-compliant server that does not support public commands. In such a situation, in order to receive the OK response from the service providing server 100, the mediation server 50 must transmit an HTTP command including an AT that can receive the service from the service providing server 100. Therefore, the mediation server 50 acquires the AT from the MFP 10 by executing the following processes shown in FIG. The first acquisition unit 84 of the mediation server 50 first transmits a user information transmission command 220 to the MFP 10.

  The control unit 30 of the MFP 10 receives the user information transmission command 220 from the mediation server 50. In this case, the control unit 30 transmits a list 222 (a list of four user information in the example of FIG. 4) of a plurality of user information (that is, all user information) stored in the memory 34 to the mediation server 50. To do. As shown in the list 222, in this embodiment, the plurality of pieces of user information are two pieces of user information that can receive a service from the service providing server 100 (that is, “Alice-AAA-GGG”, “Catherine”). -AAA-III ") and two pieces of user information (ie," Bob-BBB-HHH ")," 2 "that can receive services from a service providing server (for example, the service providing server 110) different from the service providing server 100 David-CCC-JJJ ").

The first acquisition unit 84 of the mediation server 50 acquires a plurality of user information by receiving the list 222 from the MFP 10. As described above, in the process of FIG. 3, the selection unit 82 of the mediation server 50 has already selected the service name “AAA” of the service providing server 100. The display control unit 83 of the mediation server 50 selects one or more pieces of user information 224 (two in the example of FIG. 4) including the selected service name “AAA” from the plurality of pieces of user information included in the list 222. User information (ie, “Alice-AAA-GGG”, “Catherine-AAA-III”) is extracted, and then the display control unit 83 supplies one or more extracted user information 224 to the MFP 10 (ie, transmission). In this way, the mediation server 50 can appropriately display the account selection screen described later on the display 14 of the MFP 10 by executing the extraction and supply of the user information 224.

  When the display control unit 83 supplies the extracted one or more pieces of user information 224 to the MFP 10, the display control unit 83 further instructs a command (hereinafter, an AT transmission instruction corresponding to account information selected from an account selection screen described later). (Referred to as a “send command”) is supplied to the MFP 10. For example, the display control unit 83 instructs the transmission of the AT “GGG” corresponding to the account information “Alice-AAA” and the transmission of the AT “III” corresponding to the account information “Catherine-AAA”. The transmission command is supplied to the MFP 10.

  The control unit 30 of the MFP 10 receives one or more user information 224 and a transmission command from the mediation server 50. In this case, the display control unit 43 of the MFP 10 describes one or more account information (that is, display name and service name) included in the one or more user information 224 in the display template stored in the memory 34 in advance. Then, display data representing the account selection screen is generated. Then, the display control unit 43 supplies the generated display data to the display 14. Thereby, the display 14 displays an account selection screen.

As shown in FIG. 4, in the account selection screen, two pieces of account information including the service name “AAA” of the service providing server 100 (ie, “Alice-AAA”, “Catherine-AAA”)
And two pieces of account information (ie, “Bob-BBB”, “David-CCC”) including the service name of another service providing server (for example, the service name “BBB” of the service providing server 110) It is not described. That is, on the account selection screen, of the four account information stored in the memory 34, two account information that can receive a service from the service providing server 100 are different from the other two account information. It is distinguished. For this reason, the target user can appropriately select account information that can receive a service from the service providing server 100 from the account selection screen displayed on the display 14.

The target user operates the operation unit 12 to select account information (for example, “Alice-AAA”) including the display name of the target user from the account selection screen. In this case, the control unit 30 transmits the AT 226 (for example, “GGG”) corresponding to the selected account information to the mediation server 50 in accordance with the transmission command.

  The second acquisition unit 85 of the mediation server 50 acquires the AT 226 by receiving the AT 226 from the MFP 10. In this case, the command communication unit 86 of the mediation server 50 generates an HTTP image request command 228 using the URL 100 a and the first API corresponding to the service providing server 100. The generation method of the image request command 228 is the same as the generation method of the image request command 206 of FIG. However, the image request command 228 includes an AT 226. That is, the image request command 228 is not a public command. In this respect, the image request command 228 is different from the image request command 206 of FIG. Then, the command communication unit 86 transmits an image request command 228 to the service providing server 100.

Upon receiving the image request command 228, the service providing server 100 transmits an HTTP response 230 to the mediation server 50. Specifically, the service providing server 100 first performs authentication using the AT 226 included in the image request command 228. If the target user has selected appropriate account information from the account selection screen, authentication will normally succeed. For this purpose, the service providing server 100 specifies the URL 100b of the resource image file based on the specific ID (that is, the ID for specifying the thumbnail image file) included in the image request command 228, and sets the URL 100b. A response 230 including the request is transmitted to the mediation server 50.

  The command communication unit 86 of the mediation server 50 receives the response 230 from the service providing server 100. In this case, the specific process execution unit 89 of the mediation server 50 generates the HTTP template 232. The HTTP template 232 is a template for the MFP 10 to generate an image request command 234 (described later) and transmit the image request command 234 to the service providing server 100. The method for generating the HTTP template 232 is the same as the method for generating the HTTP template 210 of FIG. However, the specific process execution unit 89 generates the HTTP template 232 so that the image request command 234 including the AT 226 is transmitted from the MFP 10 to the service providing server 100. That is, the HTTP template 232 includes the AT 226. In this respect, the HTTP template 232 is different from the HTTP template 210 of FIG. Then, the specific process execution unit 89 transmits the HTTP template 232 to the MFP 10.

  The subsequent processing is substantially the same as the processing in FIG. 3, but differs in the following points. That is, the control unit 30 of the MFP 10 transmits the image request command 234 including the AT 226 to the service providing server 100 using the HTTP template 232. Upon receiving the image request command 234, the service providing server 100 executes authentication using the AT 226 included in the image request command 234. When the authentication is successful, the service providing server 100 transmits the resource image file 240 to the MFP 10. As a result, the print execution unit 18 of the MFP 10 prints the resource image (that is, the flower image) represented by the resource image file 240 on the print medium. Thereby, the target user can acquire a printed print medium.

(Effects of the first embodiment)
As shown in FIG. 3, the mobile terminal 150 acquires the thumbnail data 202 from the service providing server 100 and displays a thumbnail page (see the upper diagram in FIG. 2). Then, the target user causes the MFP 10 to print an image (that is, a flower image) included in the thumbnail page by bringing the mobile terminal 150 close to the MFP 10 while the thumbnail page is displayed on the mobile terminal 150. Can do.

  As shown in FIGS. 3 and 4, the MFP 10 does not execute printing according to the thumbnail data 202 but executes printing according to the resource image file 240. As described above, the number of pixels of the resource image included in the resource image file 240 is larger than the number of pixels of the thumbnail image included in the thumbnail data 202. Therefore, if the MFP 10 employs a configuration in which printing is performed according to the resource image file 240 as in this embodiment, a high-quality print result can be provided to the target user. In addition, the target user normally does not want to print text such as the title “photo album” and the comment “flower image” included in the thumbnail page, and only the image included in the thumbnail page (that is, the flower image). Want to be printed. According to this embodiment, it is possible to provide a print result desired by the target user. The MFP 10 can normally interpret JPEG format data such as the resource image file 240 (that is, can generate CMYK binary data from the JPEG format data), but thumbnail data. HTML format data such as 202 cannot be interpreted. According to the present embodiment, the mediation server 50 can cause the MFP 10 to appropriately execute printing in order to cause the MFP 10 to execute printing according to the resource image file 240 instead of the thumbnail data 202.

As described above, the mobile terminal 150 can acquire the resource image file 240 from the service providing server 100 when a predetermined operation is executed by the user while the thumbnail page is displayed. To this end, it is conceivable that the mobile terminal 150 adopts a configuration (hereinafter referred to as “comparison configuration”) that transmits the acquired resource image file 240 to the MFP 10 and causes the MFP 10 to execute printing.

  However, in order to adopt the configuration of the comparative example, the mobile terminal 150 generates a print instruction that instructs the MFP 10 to execute printing, and a special application for transmitting the print instruction and the resource image file 240 to the MFP 10. Must have. For example, it may be possible to adopt a configuration in which the resource image file 240 is transmitted using NFC communication. However, in order to employ such a configuration, the mobile terminal 150 must include a special application for transmitting the print instruction and the resource image file 240 using NFC communication. Further, it is conceivable to employ a configuration in which the resource image file 240 is transmitted using Wi-Fi communication. However, in order to employ such a configuration, the mobile terminal 150 must include a special application for transmitting the print instruction and the resource image file 240 using Wi-Fi communication. The MFP 10 and the portable terminal 150 must exist in the same network. As described above, in order to employ the configuration of the comparative example, the target user must install a special application on the mobile terminal 150, and the mobile terminal 150 uses the Wi-Fi communication to download the resource image file 240. In the case of transmission to the MFP 10, an environment in which the MFP 10 and the portable terminal 150 exist in the same network must be maintained.

  According to the present embodiment, it is assumed that a special application is not installed in the mobile terminal 150 and the MFP 10 and the mobile terminal 150 do not exist in the same network. In such a situation, the configuration of the comparative example cannot be adopted, but in this embodiment, as shown in FIGS. 3 and 4, the MFP 10 can appropriately execute printing. Note that, according to the present embodiment, even when the MFP 10 and the mobile terminal 150 exist in the same network and no special application is installed in the mobile terminal 150, as shown in FIGS. The MFP 10 can appropriately execute printing.

  As shown in FIG. 3, when receiving the URL notification 204, the mediation server 50 uses the URL 100 a to select the service providing server 100 from the plurality of service providing servers 100 and 110. As shown in FIG. 4, the mediation server 50 can receive a service from the selected service providing server 100 among all the account information stored in the MFP 10 (that is, four pieces of account information). Two pieces of account information (that is, “Alice-AAA” and “Catherine-AAA”) are displayed on the display 14 of the MFP 10. At this time, the other two pieces of account information (“Bob-BBB”, “David-CCC”) are not displayed on the display 14 of the MFP 10. Therefore, compared to a configuration in which all account information (that is, four pieces of account information) stored in the MFP 10 is displayed, the target user can easily obtain account information that can receive a service from the service providing server 100. You can choose.

As shown in FIG. 3, when receiving the URL notification 204, the mediation server 50 transmits an image request command 206, which is a public command, to the service providing server 100 using the URL 100 a. Then, when the mediation server 50 receives the response 208 including the URL 100b from the service providing server 100 (that is, in the case of YES in S12), the intermediary server 50 performs processing for causing the MFP 10 to execute printing according to the resource image file 240 (that is, (Generate and send HTTP template 210). Therefore, even if the mediation server 50 does not acquire the AT 226 for receiving the service from the service providing server 100 (that is, without executing various communications shown in FIG. 4 between the mediation server 50 and the MFP 10). ), It is possible to cause the MFP 10 to appropriately execute printing according to the resource image file 240.

(Correspondence)
The MFP 10, the portable terminal 150, and the service providing server 100 are examples of “data processing device”, “terminal device”, and “specific service providing server”, respectively. The mediation server 50 is an example of a “control server” and a “control device for a data processing device”. The thumbnail data 202, the thumbnail image, and the resource image file 240 are examples of “specific web page data”, “target image”, and “image file”, respectively.

  The image request command 228 and the response 230 are examples of “first type command” and “first type response”, respectively. Therefore, the process of transmitting the image request command 228 to the service providing server 100 and receiving the response 230 is an example of the process executed by the “first command communication unit”. The image request command 206 (that is, a public command) is an example of “second type command” and “specific command”. The response 208 is an example of a “second type response” and a “specific response”. Therefore, the process of transmitting the image request command 206 to the service providing server 100 and receiving the response 208 is an example of a process executed by the “second command communication unit” and the “command communication unit”. Wi-Fi communication and NFC communication are examples of “first type communication” and “second type communication”, respectively. The process of generating the HTTP template 210 (or 232) and the process of transmitting the HTTP template 210 (or 232) are examples of the “specific process”.

(Second embodiment)
Subsequently, a second embodiment will be described with reference to FIG. In this embodiment, the memory 74 of the mediation server 50 stores a server table in addition to the service table. As shown in FIG. 5, in the server table, for each of the plurality of service providing servers 100 and 110, the service name of the service providing server (for example, “AAA”) and whether the service providing server is a corresponding server. Information indicating whether or not (“OK” or “NG”) is associated. “OK” indicates that the service providing server is a compatible server, that is, the service providing server can transmit an OK response in response to the public command. “NG” indicates that the service providing server is a non-compliant server, that is, the service providing server is a server that transmits an NG response in response to a public command. The vendor of the MFP 10 investigates whether various known service providing servers 100 and 110 are compatible servers, and stores a server table in the memory 74 of the mediation server 50 in advance based on the investigation result.

Each process until the mediation server 50 selects the service providing server 100 is the same as that in FIG. 3 of the first embodiment. In S <b> 11, the second determination unit 88 of the mediation server 50 determines whether the selected service providing server 100 is a compatible server based on the server table in the memory 74. In the example of FIG. 5, “OK” is associated with the service name “AAA” corresponding to the selected service providing server 100 in the server table. For this,
The second determination unit 88 determines that the selected service providing server 100 is a compatible server (that is, YES in S11). However, in the server table, the service name “AAA”
"NG" is associated with "", the second determination unit 88 determines that the selected service providing server 100 is a non-compliant server (ie, NO in S11).

  When it is determined that the selected service providing server 100 is a compatible server (that is, YES in S11), the image request command 206 and the response 208 are communicated as in FIG. 3, and the determination in S12 is performed. Is executed. Since the selected service providing server 100 is a corresponding server, it is normally determined YES in S12. However, for example, when the service providing server 100 is changed from a compatible server to a non-compliant server after the above investigation by the vendor of the MFP 10, the response 208 is an NG response that does not include the URL 100b. In view of such a possibility, the mediation server 50 executes the determination in S12 even when YES is determined in S11.

  In the case of YES in S12, communication of the HTTP template 210, the image request command 212, and the resource image file 240 is executed as in FIG. 3, and then the printing process is executed. If NO in S11 or NO in S12, the process proceeds to FIG. Each process of FIG. 4 is the same as that of the first embodiment.

  According to the present embodiment, if NO in S11, that is, if the service providing server 100 is determined to be a non-compliant server based on the server table, the command communication unit 86 of the mediation server 50 uses a public command. A certain image request command 206 is not transmitted to the service providing server 100. Thereby, it can suppress that a public command is transmitted to the non-corresponding | compatible server which does not respond | correspond to a public command. As a result, the communication load between the mediation server 50 and the service providing server 100 can be reduced.

(Third embodiment)
Subsequently, a third embodiment will be described with reference to FIG. In this embodiment, if NO in S12 of FIG. 3, that is, if the service providing server 100 is a non-compliant server, each process of FIG. 6 is executed instead of each process of FIG. In the first and second embodiments, as illustrated in FIG. 4, the mediation server 50 extracts user information 224 corresponding to the selected service providing server 100 and supplies the user information 224 to the MFP 10. On the other hand, in this embodiment, not the mediation server 50 but the MFP 10 executes the above extraction process.

The display control unit 83 of the mediation server 50 stores the server information 250 indicating the selected service providing server 100, that is, the server information 250 including the selected service name “AAA”.
10 is supplied (ie, transmitted).

  The control unit 30 of the MFP 10 receives server information from the mediation server 50. In this case, the display control unit 43 of the MFP 10 extracts the user information 224 using a method similar to the method by which the display control unit 83 of the mediation server 50 of the first embodiment extracts the user information 224 (see FIG. 4). To do. And the display control part 43 displays an account selection screen on the display 14 using the user information 224 using the method similar to 1st Example. The subsequent processes are the same as in the first embodiment.

According to this embodiment, the mediation server 50 supplies server information 250 indicating the service providing server 100 to the MFP 10 to extract the user information 224 and account information (that is, “Alice” included in the user information 224). -AAA "," Catherine-AAA ") on the display 14, and the MFP 10 can be appropriately executed. Also in this embodiment, as in the first and second embodiments, the mediation server 50 can display appropriate account information on the display 14 of the MFP 10. In particular, in this embodiment, communication of the list 222 and the user information 224 (see FIG. 4) is not executed between the MFP 10 and the mediation server 50. For this reason, the communication load between the MFP 10 and the mediation server 50 can be reduced.

(Fourth embodiment)
Subsequently, a fourth embodiment will be described with reference to FIGS. In the first to third embodiments described above, since the MFP 10 does not include APIs corresponding to the service providing servers 100 and 110, the mediation server 50 is provided. On the other hand, in the present embodiment, the MFP 10 includes APIs corresponding to the service providing servers 100 and 110, and the mediation server 50 is not provided. In this embodiment, the memory 34 of the MFP 10 stores a service table.

  Each processing until the URL 100a is transmitted from the portable terminal 150 to the MFP 10 is the same as that in FIG. 3 of the first embodiment. The receiving unit 41 of the MFP 10 receives the URL 100a from the portable terminal 150 via the NFC I / F 16 (that is, using NFC communication). In this case, the selection unit 42 of the MFP 10 refers to the service table in the memory 34 by using the same method as the selection unit 82 of the mediation server 50 of the first embodiment, and the plurality of service providing servers 100 and 110. The service providing server 100 is selected from the list.

  Next, the command communication unit 46 of the MFP 10 generates an HTTP image request command 306 using the URL 100 a and the first API corresponding to the selected service providing server 100. The method for the command communication unit 46 to generate the image request command 306 is the same as the method for the command communication unit 86 of the mediation server 50 of the first embodiment to generate the image request command 206 (see FIG. 3). That is, the image request command 306 is a public command that does not include an AT. Since the MFP 10 includes the first API, the image request command 306 can be appropriately generated. The command communication unit 46 transmits the image request command 306 to the service providing server 100 and receives the response 308.

  In step S <b> 42, the first determination unit 47 of the MFP 10 determines whether the service providing server 100 is a compatible server based on the response 308. The determination method of S42 is the same as the determination method of S12 of FIG. 3 of the first embodiment.

  If YES is determined in S42, that is, if the service providing server 100 is a compatible server, the specific process execution unit 49 of the MFP 10 generates an image request command 312 and sends the image request command 312 to the service providing server. To 100. The image request command 312 is an HTTP command that can be generated without using the first API, like the image request command 212 of FIG. The request destination URL of the image request command 312 is the URL 100b (that is, the URL of the resource image file 240) included in the response 308. The image request command 312 is a public command that does not include an AT.

  Upon receiving the image request command 312 from the MFP 10, the service providing server 100 transmits the resource image file 240 to the MFP 10 in accordance with the request destination URL 100 b included in the image request command 312.

  The specific process execution unit 49 of the MFP 10 receives the resource image file 240 from the service providing server 100. In this case, the specific process execution unit 49 converts the resource image file 240 into binary data of CMYK and supplies the data to the print execution unit 18. Thereby, the printing process is executed.

On the other hand, if NO is determined in S42, the display control unit 43 of the MFP 10 selects the service selected from the plurality of user information stored in the memory 34, as shown in FIG. One or more pieces of user information including the name “AAA” (ie, “Alice-AAA-GGG”, “Ca
therine-AAA-III "). Next, the display control unit 43 adds one or more pieces of account information (that is, “Alice-AAA”, “Catherine” included in the extracted one or more pieces of user information to the display template stored in the memory 34 in advance. -AAA ") and the account selection screen is displayed on the display 14.

When the account information (for example, “Alice-AAA”) is selected from the account selection screen, the second acquisition unit 45 of the MFP 10 performs AT 326 (for example, “GGG”) associated with the selected account information. Is obtained from the memory 34 to obtain the AT 326. Next, the command communication unit 46 of the MFP 10 generates an image request command 328 including the AT 326 using the URL 100 a and the first API corresponding to the service providing server 100. The generation method of the image request command 328 is the same as the generation method of the image request command 228 in FIG. Since the MFP 10 includes the first API, the image request command 328 can be appropriately generated. Then, the command communication unit 46 transmits an image request command 328 to the service providing server 100.

  Upon receiving the image request command 328, the service providing server 100 normally authenticates successfully and transmits a response 330 including the URL 100b to the MFP 10.

  The command communication unit 46 of the MFP 10 receives the response 330 from the service providing server 100. In this case, the specific process execution unit 49 of the MFP 10 generates an image request command 334. The image request command 334 is an HTTP command that can be generated without using the first API, like the image request command 234 of FIG. The request destination URL of the image request command 334 is the URL 100 b included in the response 330. The image request command 334 includes an AT 326.

  The subsequent processing is almost the same as the processing in FIG. That is, the control unit 30 of the MFP 10 transmits an image request command 334 including the AT 326 to the service providing server 100. When the service providing server 100 receives the image request command 334, the service providing server 100 performs authentication using the AT 326 included in the image request command 334. When the authentication is successful, the service providing server 100 transmits the resource image file 240 to the MFP 10. As a result, the print execution unit 18 of the MFP 10 prints the resource image (that is, the flower image) represented by the resource image file 240 on the print medium. Thereby, the target user can acquire a printed print medium.

  In this embodiment, the same effect as in the first embodiment can be obtained. In particular, since it is not necessary to provide the mediation server 50, the configuration of the communication system 2 can be simplified. The memory 34 of the MFP 10 may further store a server table (see FIG. 5) of the second embodiment. In this case, after the service providing server 100 is selected from the plurality of service providing servers 100 and 110, the second determination unit 48 of the MFP 10 performs a server table similar to S11 in FIG. 5 of the second embodiment. Based on the above, it may be determined whether or not the service providing server 100 is a compatible server. Then, if it is determined that the service providing server 100 is a compatible server, the command communication unit 46 of the MFP 10 transmits an image request command 306 to the service providing server 100, and the service providing server 100 is a non-compliant server. If it is determined, the image request command 306 does not have to be transmitted to the service providing server 100 (that is, each process of FIG. 8 may be executed). According to this configuration, the same effect as in the second embodiment can be obtained.

(Correspondence)
In this embodiment, the MFP 10 is an example of a “data processing apparatus”, and the control unit 30 of the MFP 10 is an example of a “control apparatus for a data processing apparatus”. Also, the image request command 328
The response 330 is an example of a “first type command” and a “first type response”, respectively. Therefore, the process of transmitting the image request command 328 to the service providing server 100 and receiving the response 330 is an example of the process executed by the “first command communication unit”. The image request command 306 (that is, a public command) is an example of “second type command” and “specific command”. The response 308 is an example of a “second type response” and a “specific response”. Therefore, the process of transmitting the image request command 306 to the service providing server 100 and receiving the response 308 is an example of the process executed by the “second command communication unit” and the “command communication unit”. Processing to generate image request command 312, processing to transmit image request command 312 and receive resource image file 240, processing to generate binary data of CMYK from resource image file 240, and print execution unit The processing supplied to 18 is an example of “specific processing”.

  Specific examples of the present invention have been described in detail above, but these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples illustrated above. For example, the following modifications are included.

(Modification 1)
In each of the embodiments described above, the NFC connection is established between the mobile terminal 150 and the MFP 10 in a state where the thumbnail page (see the upper diagram in FIG. 2) is displayed on the mobile terminal 150, that is, It is assumed that the URL 100a of the thumbnail data 202 is transmitted from the portable terminal 150 to the MFP 10. However, an NFC connection may be established between the mobile terminal 150 and the MFP 10 in a state where the resource page (see the lower diagram in FIG. 2) is displayed on the mobile terminal 150. In this case, the URL 100 b of the resource image file 240 is transmitted from the portable terminal 150 to the MFP 10.

  In the present modification, the reception unit 41 of the MFP 10 receives the URL 100b using NFC communication (that is, via the NFC I / F 16). Then, the reception unit 81 of the mediation server 50 receives the URL 100b via the MFP 10. In this case, as in the first to third embodiments, the selection unit 82 selects the service providing server 100. Then, the command communication unit 86 uses the URL 100b and the first API to generate a specific image request command that does not include an AT. The specific image request command is a command for requesting the service providing server 100 to transmit the URL 100b of the resource image file 240. More specifically, the command communication unit 86 generates a specific image request command including the ID included in the URL 100b and specifying the resource image file 240. Then, the command communication unit 86 transmits a specific image request command to the service providing server 100. Since the mediation server 50 acquires the URL 100b from the MFP 10, it is not necessary to acquire the URL 100b from the service providing server 100. However, the mediation server 50 transmits the specific image request command to the service providing server 100 in order to determine whether the service providing server 100 is a compatible server or a non-compliant server.

  When the service providing server 100 is a compatible server, the service providing server 100 transmits an OK response including the URL 100b to the mediation server 50. On the other hand, when the service providing server 100 is a non-compliant server, the service providing server 100 transmits an NG response not including the URL 100b to the mediation server 50.

  The command communication unit 86 of the mediation server 50 receives a response from the service providing server 100. Next, the first determination unit 87 of the mediation server 50 determines that the service providing server 100 is a compatible server when the URL 100b is included in the response, and provides the service when the URL 100b is not included in the response. It is determined that the server 100 is a non-compliant server.

  When it is determined that the service providing server 100 is a compatible server, the specific process execution unit 89 of the mediation server 50 generates an HTTP template including the URL 100b (however, an HTTP template not including AT). The HTTP template is the same as the template 210 in FIG. Each process after this is the same as each process of FIG. On the other hand, when it is determined that the service providing server 100 is a non-compliant server, the same processes as in FIG. 4 are executed.

  Also according to this modification, the same effect as the first embodiment can be obtained. In the present modification, the resource page including the resource image represented by the resource image file 240 and the URL 100b are examples of “specific web page data” and “first location information”, respectively.

(Modification 2)
In each of the above embodiments, the display control unit 83 (or 43) causes the display 14 to display an account selection screen including the display name and the service name. That is, in each of the above embodiments, the display name and the service name are examples of “account information”. Instead, the display control unit 83 (or 43) may display an account selection screen including a display name, a service name, and an AT on the display 14. In this modification, the display name, service name, and AT are examples of “account information”. In another modification, the display control unit 83 (or 43) may cause the display 14 to display an account selection screen including only the display name. In this modification, the display name is an example of “account information”. In yet another modification, the display control unit 83 (or 43) has account information different from the display name, service name, etc. (for example, account name, user ID, e-mail address, etc. registered in the service providing server 100). ) May be displayed on the display 14.

(Modification 3)
In each of the embodiments described above, the display control unit 83 (or 43), among the four account information stored in the memory 34 of the MFP 10, two account information corresponding to the service providing server 100 (that is, “ Alice-AAA ”and“ Catherine-AAA ”) are displayed on the display 14. That is, in each of the above embodiments, “M” is 4 and “N” is 2. However, the total number of account information stored in the memory 34 may be larger than 4 or smaller than 4. That is, “M” may be an integer of 2 or more. Further, the number of account information corresponding to the service providing server 100 stored in the memory 34 may be larger than two or smaller than two. That is, “N” may be an integer from 1 to M.

(Modification 4)
In each of the embodiments described above, the display control unit 83 (or 43) displays two pieces of account information corresponding to the service providing server 100 among the four pieces of account information stored in the memory 34 of the MFP 10 on the display 14. The other account information is not displayed on the display 14 so that the former account information is displayed on the display 14 in a manner distinguishable from the latter account information. Instead, the display control unit 83 (or 43) displays the former account information on the display 14 in a first color (for example, red), and the latter account information is different from the first color. You may display on the display 14 with a color (for example, black). In this case, (1) all of the former account information and the latter account information may have an aspect that can be selected by the user, or (2) the former account information has an aspect that can be selected by the user. The latter account information may have a mode (for example, a gray-out mode) that cannot be selected by the user. This modification is also included in the configuration of “displaying N pieces of account information in a manner distinguishable from MN pieces of account information”.

(Modification 5)
In each of the embodiments described above, the display control unit 83 (or 43) causes the display 14 to display account information corresponding to the service providing server 100 among all account information stored in the memory 34 of the MFP 10, and so on. Account information corresponding to the service providing server is not displayed on the display 14. Instead, the display control unit 83 (or 43) may cause the display 14 to display all account information stored in the memory 34 of the MFP 10. That is, it is sufficient that the user can select at least account information corresponding to the service providing server 100. Generally speaking, the display control unit 83 (or 43) may display at least N pieces of account information among the M pieces of account information on the display.

(Modification 6)
In the first to third embodiments described above, the specific process execution unit 89 of the mediation server 50 generates the HTTP template 210 (or 232) and transmits the HTTP template 210 (or 232) to the MFP 10. Alternatively, the specific process execution unit 89 may transmit the URL 100b and the print instruction to the MFP 10 without generating the HTTP template 210 (or 232). When the URL 100b and the print instruction are received, the control unit 30 of the MFP 10 generates an image request command 212 (or 234) including the URL 100b as a request destination URL, and the image request command 212 (or 234) is a service providing server. 100 may be transmitted. Since the image request command 212 (or 234) is an HTTP command that can be generated without using the first API, the MFP 10 can appropriately generate the image request command 212 (or 234). In the present modification, the process of transmitting the URL 100b and the print instruction is an example of the “specific process”.

(Modification 7)
The “authentication information” is not limited to the access token, but may be other information (for example, user ID, password, etc.) used by the service providing servers 100 and 110 for authentication.

(Modification 8)
The “first type wireless communication” is not limited to Wi-Fi communication (that is, HTTP communication), and may be, for example, wireless communication such as 3G conforming to the standard of IMT2000 (abbreviation of International Mobile Telecommunication 2000). Moreover, it replaces with HTTP communication and the communication according to other protocols (for example, HTTPS etc. according to HTTP) for communicating web data may be utilized. The “second type wireless communication” is not limited to NFC communication, and may be infrared communication, BlueTooth (registered trademark) communication, or the like.
