The server 30 is a computer for providing a WEB service by a service provider such as an electronic file storage service. Examples of the WEB service include cloud services such as Facebook (Facebook registered trademark) and social networking services (SNS Social Networking Service).

(Mobile device processing)
When the user of the mobile terminal 10 performs an operation of starting the application software for accessing the above-described WEB service through the operation unit 14, the terminal control unit 11 can directly access the server without going through the MFP 20, for example. An access selection screen (not shown) for selecting either indirect access to access the server via the MFP 20 is displayed on the display unit 15. And if a user performs operation which selects indirect access, the terminal control part 11 will perform the portable terminal process shown in FIG. 8 and 9 show sequences among the portable terminal 10, the MFP 20, and the server 30 at the time of data download execution and data upload execution.

  The terminal control unit 11 displays an instruction screen (not shown) on the display unit 15 (S1). The user can give various instructions described below by operating the operation unit 14 while referring to the instruction screen. At this time, the operation unit 14 functions as a reception unit. Specifically, the user can specify a WEB service to be used on the instruction screen. In the memory 11B, designation information of one or a plurality of WEB services is stored in advance, and the mobile terminal 10 refers to the instruction information of the WEB service and displays one or a plurality of WEB services as options on the instruction screen. Can be displayed. The instruction information is information for instructing the MFP 20 to log in to a specific WEB service (for example, a URL or a file name of a storage location). In the following description, the WEB service designation information, the mobile terminal 10 and the user And at least one of the identification information.

  Further, the user can issue an execution command by selecting either data download or data upload on the instruction screen. Data download is downloading data from the server 30 to the mobile terminal 10 via the MFP 20, and data upload is uploading data from the mobile terminal 10 to the server 30 via the MFP 20. The memory 11B can store one or more data such as scan data, image data, and text data acquired from the MFP 20, and the mobile terminal 10 can store one or more data stored in the memory 11B. Can be displayed as a data upload candidate on the instruction screen.

  If the terminal control unit 11 determines that the user has not performed a determination operation such as a WEB service designation or a data download or data upload execution command (S2: NO), the terminal control unit 11 stands by and determines that the determination operation has been performed. If so (S2: YES), it is determined whether the NFC interface 13 has received a detection radio wave for NFC from the MFP 20 (S3). Here, the MFP 20 emits a detection radio wave from the NFC interface 23 when the power is turned on.

  If the terminal control unit 11 determines that the detected radio wave is not received (S3: NO), the terminal control unit 11 stands by. On the other hand, for example, when the user performs a so-called NFC touch in which the mobile terminal 10 is brought close to the MFP 20, the distance between the mobile terminal 10 and the MFP 20 becomes less than the distance (for example, 10 cm) that radio waves reach each other. 11 determines that the detected radio wave has been received (S3: YES), transmits a response radio wave to the MFP 20, establishes an NFC communication connection (NFC communication session) between the mobile terminal 10 and the MFP 20, and starts NFC communication (S4).

  The terminal control unit 11 transmits the Wi-Fi connection request and the instruction information to the MFP 20 by NFC communication (S5). The process of S5 is an example of an instruction transmission process and a communication establishment process. The Wi-Fi connection request includes Wi-Fi connection information (an example of setting information) for establishing a Wi-Fi communication connection (Wi-Fi communication session). The Wi-Fi connection information includes, for example, a communication method, an authentication method, an encryption method, an SSID (Service Set IDentifier) that is an identifier for identifying a wireless network, and a unique identifier of an access destination for constructing the wireless network. A certain BSSID (Basic Service Set IDentifier) or the like is included.

(1) Terminal Download Process When the terminal control unit 11 determines that data download has been selected in S2 after transmission of the Wi-Fi connection request or the like (S6: YES), the terminal control unit 11 executes the terminal download process shown in FIG. (S7).

  If the terminal control unit 11 determines that the Wi-Fi connection response to the Wi-Fi connection request and the login success / failure information have not been received from the MFP 20 (S11: NO), the terminal control unit 11 stands by and receives the Wi-Fi connection response. If the MFP 20 has determined that the MFP 20 has successfully logged in to the WEB service, it refers to the login success / failure information (S12). The process of S12 is an example of a login determination process.

  If the terminal control unit 11 determines that the login to the WEB service has not been successful (S12: NO), the terminal control unit 11 executes an error notification process without establishing a Wi-Fi communication connection between the mobile terminal 10 and the MFP 20. (S13). The error notification process is a process for notifying the user of an error in which data download cannot be performed, and the terminal control unit 11 causes the display unit 15 to display an error message or the like. In the error notification process, in addition to the display by the display unit 15, various notification methods such as light emission of a light emitting unit (not shown), vibration of a vibrator, and sound generation of a speaker can be used. After executing the error notification process, the terminal control unit 11 ends the terminal download process and the mobile terminal process.

  On the other hand, if the terminal control unit 11 determines that the login to the WEB service has been successful (S12: YES), the terminal control unit 11 establishes a Wi-Fi communication connection between the mobile terminal 10 and the MFP 20 (S14). As described above, since the Wi-Fi communication connection is established by the NFC touch, the Wi-Fi communication connection is efficiently established as compared with the configuration in which the user manually inputs the Wi-Fi connection information to the MFP 20. Can be made. In addition, since the Wi-Fi communication connection is established on the condition that it is determined that the login is successful, the Wi-Fi communication connection is established even though the login is not started and data communication cannot be performed. It is possible to suppress the state from being unnecessarily continued.

  After establishing the Wi-Fi communication connection, the terminal control unit 11 starts to receive data downloaded from the WEB service by the MFP 20 (hereinafter referred to as download data) from the MFP 20 by Wi-Fi communication (S15). The process of S15 is an example of a data communication process. Thereafter, the terminal control unit 11 determines whether or not reception of all download data has been completed (S16). For example, the terminal control unit 11 determines whether the reception is completed based on the presence / absence of end data added to the end of the download data, the presence / absence of reception of a completion notification from the MFP 20, and the like.

  If the terminal control unit 11 determines that the reception has not been completed (S16: NO), it continues to receive the download data as it is, and if it is determined that the reception has been completed (S16: YES), it immediately starts Wi-Fi. A disconnection process for disconnecting the communication connection is executed (S17). The terminal control unit 11 may be configured to disconnect the Wi-Fi communication connection within a predetermined reference time (for example, 1 minute) from the time when it is determined that the reception is completed. As a result, it is possible to prevent the Wi-Fi communication connection from being established for a long time despite the completion of reception of the download data. In the WFD method, unless the connection of WFD communication is disconnected, the mobile terminal 10 monopolizes wireless communication with the MFP 20, so it is particularly important that other communication devices perform wireless communication with the MFP 20 by disconnecting early. It is valid.

  After disconnecting the Wi-Fi communication connection, the terminal control unit 11 executes a data download completion notification process (S18). This completion notification process is a process for notifying the user that the data download has been completed, and the terminal control unit 11 causes the display unit 15 to display a message to that effect. In the completion notification process, the various notification methods described above can be used in addition to the display by the display unit 15. After executing the completion notification process, the terminal control unit 11 ends the terminal download process and the mobile terminal process.

(2) Terminal Upload Process When the terminal control unit 11 determines that data upload has been selected in S2 after transmitting the Wi-Fi connection request or the like (S6: NO), the terminal control unit 11 executes the terminal upload process shown in FIG. (S8).

  When determining that the Wi-Fi connection response to the Wi-Fi connection request has not been received from the MFP 20 (S21: NO), the terminal control unit 11 waits and determines that the Wi-Fi connection response has been received. In the case (S21: YES), a Wi-Fi communication connection is established between the mobile terminal 10 and the MFP 20 (S22). After establishing the Wi-Fi communication connection, the terminal control unit 11 transmits data to be uploaded to the WEB service via the MFP 20 (hereinafter referred to as upload data) to the MFP 20 by Wi-Fi communication (S23). The process of S23 is an example of a data communication process.

  Thereafter, if the terminal control unit 11 determines that the login success / failure information has not been received from the MFP 20 (S24: NO), the terminal control unit 11 stands by and determines that the login success / failure information has been received (S24: YES). With reference to the information, it is determined whether or not the MFP 20 has successfully logged in to the WEB service (S25). The process of S25 is an example of a login determination process.

  When it is determined that the login to the WEB service has not been successful (S25: NO), the terminal control unit 11 immediately disconnects the Wi-Fi communication connection (S26). Accordingly, it is possible to prevent the Wi-Fi communication connection establishment state from being unnecessarily continued even though login fails and data communication cannot be performed.

  Moreover, the terminal control part 11 performs an error alerting | reporting process (S27). The error notification process is a process for notifying the user of an error in which data upload cannot be performed, and the terminal control unit 11 causes the display unit 15 to display an error message or the like. In the error notification process, the various notification methods described above can be used. After executing the error notification process, the terminal control unit 11 ends the terminal download process and the mobile terminal process.

  On the other hand, if the terminal control unit 11 determines that the login to the WEB service has been successful (S25: YES), and determines that the upload completion notification has not been received from the MFP 20 (S28: NO), the terminal control unit 11 waits and uploads. If it is determined that a completion notification has been received (S28: YES), the Wi-Fi communication connection is disconnected (S29), and a data upload completion notification process is executed (S30). This completion notification process is a process for notifying the user that the data upload has been completed, and the terminal control unit 11 causes the display unit 15 to display a message to that effect. In the completion notification process, the various notification methods described above can be used in addition to the display by the display unit 15. After executing the completion notification process, the terminal control unit 11 ends the terminal download process and the mobile terminal process.

(MFP processing)
When the NFC interface 23 receives the response radio wave from the mobile terminal 10 by the NFC touch described above and the MFP control unit 21 executes communication for establishing an NFC communication connection between the mobile terminal 10 and the MFP 20, the MFP The control unit 21 executes the MFP process shown in FIG.

  The MFP controller 21 determines whether or not the Wi-Fi connection request and instruction information are received from the mobile terminal 10 (S41). The process of S41 is an example of an instruction reception process. When the MFP control unit 21 determines that a Wi-Fi connection request or the like has not been received (S41: NO), the MFP control unit 21 stands by and determines that a Wi-Fi connection request or the like has been received (S41: YES). With reference to the information, the mobile terminal 10 determines whether data download or data upload is selected (S42).

(1) MFP Download Processing When the MFP control unit 21 determines that data download has been selected (S42: YES), it executes MFP download processing shown in FIG. 6 (S43). The MFP control unit 21 attempts a login process for declaring the start of use of a specific WEB service based on the instruction information (S51). Specifically, correspondence information between identification information of at least one of the mobile terminal 10 and the user and login information (for example, a user ID and a password) is stored in the memory 12B in advance.

  The MFP control unit 21 extracts login information corresponding to the identification information included in the received instruction information from the correspondence information, and transmits the extracted login information to the server 30 to attempt login to the WEB service. A login result is received from the server 30. For example, when the login to the WEB server is successful, the login result includes browser screen data of the WEB service. When the login fails, the login result includes error communication.

  The MFP control unit 21 transmits a Wi-Fi connection response and login success / failure information corresponding to the login result to the mobile terminal 10 by NFC communication (S52). The MFP controller 21 refers to the login result and determines whether or not the login is successful (S53). The process of S53 is an example of a login determination process. If the MFP control unit 21 determines that the login has not been successful due to, for example, an incorrect password (S53: NO), the Wi-Fi communication connection is not established between the mobile terminal 10 and the MFP 20, The MFP download process and the MFP process are terminated.

  On the other hand, when the MFP control unit 21 determines that the login is successful (S53: YES), the MFP control unit 21 establishes a Wi-Fi communication connection between the mobile terminal 10 and the MFP 20 (S54). As described above, when executing data download, the MFP control unit 21 starts logging in to the WEB service before establishing the Wi-Fi communication connection. Thereby, compared with the structure which starts the login to a WEB service after establishment of a Wi-Fi communication connection, the login to a WEB service can be started at an early stage.

  After establishing the Wi-Fi communication connection, the MFP control unit 21 makes a download request to the server 30 based on the instruction information, and downloads data stored in a specific storage location of the WEB service from the server 30. Is started (S55), and the download data is started to be transmitted to the mobile terminal 10 by Wi-Fi communication (S56). The process of S56 is an example of a data communication process. As described above, the MFP control unit 21 starts transmission of download data to the mobile terminal 10 before the data download from the server 30 is completed. For this reason, on the mobile terminal 10 side, reception of download data can be started early after transmission of the instruction information.

  The instruction information is transmitted from the portable terminal 10 to the MFP 20 by NFC communication, and the download data is transmitted from the MFP 20 to the portable terminal 10 by Wi-Fi communication. Thereby, compared with the configuration in which the instruction information is transmitted by Wi-Fi communication, the range in which the instruction information is transmitted is limited, so that the instruction information can be suppressed from being received by another communication device. In addition, data communication can be performed at a long distance and at a higher speed than a configuration in which data communication is performed by NFC communication.

  If the MFP control unit 21 determines that the data download from the server 30 has not been completed (S57: NO), it continues the download, and if it determines that the download has been completed (S57: YES), it logs off from the WEB service. (S58). Thereafter, when the MFP control unit 21 determines that transmission of all the download data to the mobile terminal 10 has not been completed (S59: NO), the MFP control unit 21 continues the transmission and determines that transmission of all the download data has been completed. In the case (S59: YES), a disconnection process for disconnecting the Wi-Fi communication connection is immediately executed (S60).

  The MFP control unit 21 may be configured to disconnect the Wi-Fi communication connection within a predetermined reference time (for example, 1 minute) from the time when it is determined that the reception is completed. As a result, it is possible to prevent the Wi-Fi communication connection from being established for a long time despite the completion of the transmission of the download data. After disconnecting the Wi-Fi communication connection, the MFP control unit 21 ends the MFP download process and the MFP process.

(2) MFP Upload Process When the MFP control unit 21 determines that data upload has been selected (S42: NO), it executes the MFP upload process shown in FIG. 7 (S44). The MFP control unit 21 transmits a Wi-Fi connection response to the mobile terminal 10 by NFC communication (S71), and establishes a Wi-Fi communication connection between the mobile terminal 10 and the MFP 20 (S72). Then, before logging in to the WEB service, the MFP control unit 21 starts receiving upload data from the mobile terminal 10 by Wi-Fi communication (S73).

  Thereafter, the MFP controller 21 determines whether or not the amount of upload data received has reached a predetermined amount (S74). The process of S74 is an example of a transmission determination process. If the MFP control unit 21 determines that the received amount of upload data has not reached the specified amount (S74: NO), the MFP controller 21 waits and determines that the received amount of upload data has reached the specified amount (S74: YES). ) Based on the instruction information, a login process for declaring the start of use of a specific WEB service is attempted (S75).

  As described above, when data upload is selected, login to the server 30 is started after the Wi-Fi communication connection is established. Accordingly, it is possible to prevent the login to the server 30 from being started in vain even though the Wi-Fi communication connection is not established and the upload target data cannot be transmitted to the MFP 20. In addition, data upload can be started earlier after login, compared to a configuration in which login is started before transmitting data to be uploaded.

  After executing the login process, the MFP control unit 21 transmits login success / failure information corresponding to the login result to the mobile terminal 10 by Wi-Fi communication (S76). The MFP control unit 21 refers to the login result and determines whether or not the login is successful (S77). The process of S77 is an example of a login determination process. If the MFP control unit 21 determines that the login is not successful (S77: NO), the Wi-Fi communication connection is disconnected (S82), and the MFP upload process and the MFP process are terminated.

  On the other hand, if the MFP control unit 21 determines that the login is successful (S77: YES), the upload data received from the portable terminal 10 is uploaded to a specific storage location of the WEB service based on the instruction information. Is started (S78). Thereafter, when the MFP control unit 21 determines that upload of the upload data has not been completed (S79: NO), the upload control is continued, and when it is determined that the upload of the entire upload data has been completed (S79: YES), Log off from the WEB service (S80).

  After logoff, the MFP control unit 21 transmits an upload completion notification to the mobile terminal 10 via Wi-Fi communication (S81), disconnects the Wi-Fi communication connection (S82), and performs the MFP upload processing and MFP processing. finish.

(Effect of this embodiment)
The image processing system 1 transmits instruction information for instructing the login to the server 30 from the portable terminal 10 to the MFP 20, and the MFP 20 logs into the server 30 based on the instruction information. Then, the image processing system 1 downloads data from the server 30 and transmits data to the mobile terminal 10 from the MFP 20 and / or data upload to transmit data from the mobile terminal 10 to the MFP 20 and upload to the server 30. Data communication. That is, the mobile terminal 10 can perform data communication with the server 30 via the MFP 20. For this reason, when performing data communication with the server 30, it is possible to improve usability as compared with the conventional image processing system.

  In addition, the user can perform the NFC touch only by specifying the WEB service or performing a determination operation such as a data download or data upload execution command on the mobile terminal 10, without requiring any operation on the MFP 20. Download and data upload data can be performed.

<Other embodiments>
The technology disclosed in the present specification is not limited to the embodiments described with reference to the above description and drawings, and includes, for example, the following various aspects.

  The “information processing apparatus” is not limited to the portable terminal 10, and may be, for example, an installed personal computer or an electric device such as a digital camera.

  The “communication unit” is not limited to the wireless communication method, and may be a wired communication method. In short, the “communication unit” may be anything that performs communication between the mobile terminal 10 and the MFP 20.

  “Far-distance wireless communication” is not limited to wireless communication according to the WFD system, but is based on normal Wi-Fi using an access point (not shown), NFC wireless communication, infrared communication, Bluetooth (registered trademark). , Transfer Jet or the like. In short, the “far-distance wireless communication” may be any communication method having a longer communicable distance than the short-range wireless communication.

  “Near field wireless communication” may be infrared communication, Bluetooth, Transfer Jet, or the like in addition to NFC wireless communication. In short, the “short-range wireless communication” may be a communication method in which the communicable distance is shorter than that of the long-range wireless communication.

  In the above embodiment, the terminal control unit 11 and the MFP control unit 21 are configured to execute each process of FIGS. 2 to 7 by one CPU. However, the present invention is not limited to this, and the terminal control unit 11 and the MFP control unit 21 are configured to execute each process of FIGS. 2 to 7 by a plurality of CPUs, and only from a hardware circuit such as an ASIC (Application Specific Integrated Circuit) from FIG. 7 may be configured to execute the processes of FIGS. 2 to 7 by a CPU and a hardware circuit.

  The “image processing apparatus” is not limited to an MFP that can execute a print function and a scan function, but may be a printer that can execute only a print function of the print function and the scan function, or a scanner that can execute only a scan function. Further, the “image processing apparatus” may be an apparatus having a function execution unit that executes an image processing function (for example, an image display function, an image editing function, a facsimile function, etc.) different from the printing function and the scanning function.

  The “instruction information” is not limited to the identification information of the mobile terminal 10 or the like, but may be specified information of a specific WEB service and login information (for example, a user ID and a password) for logging in to the WEB service. With this configuration, the MFP 20 can log in to the server 30 using the login information received from the mobile terminal 10 as it is.

  The terminal control unit 11 may be configured to execute only one of the terminal download process and the terminal upload process. Further, the MFP control unit 21 may be configured to execute only one of the MFP download process and the MFP upload process.

  If the terminal control unit 11 determines that a Wi-Fi connection response has been received from the MFP 20 without executing the login determination process of S12 (S11: YES), the terminal control unit 11 immediately establishes a Wi-Fi communication connection (S14). ) Configuration is also acceptable. In this case, the terminal control unit 11 does not need to receive login success / failure information from the MFP 20.

  In the terminal upload process, the terminal control unit 11 executes the processes of S24 to S25 in the process of transmitting the upload data in S23, and determines that the login to the WEB service has not been successful (S25: NO). A configuration in which data transmission is interrupted and the Wi-Fi communication connection is disconnected may be employed.

  The MFP control unit 21 may be configured to start login to the WEB service after the Wi-Fi communication connection is established in the MFP download process (S54). With this configuration, it is possible to start downloading data from the server 30 early after successful login.

  The MFP control unit 21 may be configured to start transmission of download data to the mobile terminal 10 after the data download from the server 30 is completed in the MFP download process (S57: YES). With this configuration, for example, when download is interrupted due to poor communication between the server 30 and the MFP 20, it is possible to suppress the occurrence of inconvenience that part of the download data is not transmitted to the mobile terminal 10. .

  The MFP control unit 21 may be configured to log in to the WEB service when it is determined in the MFP upload process that the entire upload data has been received.

  The MFP control unit 21 may be configured to start establishment of a Wi-Fi communication connection or reception of upload data from the mobile terminal 10 after login to the WEB service (S75) in the MFP upload process. With this configuration, it is possible to prevent the establishment of a Wi-Fi communication connection and the reception of upload data from the mobile terminal 10 from being performed wastefully even though login is not possible.
