  Next, the operation in this embodiment will be described. In the present embodiment, a user brings a portable terminal 30 and a document into a store such as a convenience store, and stores the digital data of the document in the portable terminal 30 using a scan service provided by the multifunction machine 10 installed in the store. A flow of a series of processes up to will be described.

  When the user selects a scan service from the main menu (FIG. 5C) for selecting a service displayed on the operation panel 57 of the multi-function device 10, the wireless connection processing unit 18 activates the access point 60, and Wi- An environment capable of Fi connection is constructed (step 101). At this time, it may be displayed on the operation panel 57 that the portable terminal 30 is requested to be connected.

  The user who has selected the scan service activates an application installed in advance on the mobile terminal 30. Thereby, the processing function by each component 31-37 in the portable terminal 30 is exhibited.

  First, the wireless connection processing unit 35 in the portable terminal 30 establishes a Wi-Fi connection to the access point 60 when the application is activated (step 201). After the user selects the scan service, the user sets a document on the document table of the multifunction machine 10 and starts a reading operation. At the same time, the information management unit 33, for example, identifies the terminal itself. Identification information such as a number that can identify the terminal is transmitted as terminal information to the multifunction machine 10 (step 202). This identification information may not be information for identifying an individual terminal but may be an identification number unique to each application.

  When receiving the terminal information transmitted from the portable terminal 30, the information management unit 17 in the multifunction machine 10 holds it inside (step 102). Subsequently, the information management unit 17 determines the system based on the received terminal information, identification information (device information) such as an individual identification number unique to the own device, Wi-Fi connection date and time, session ID, and the like. When the unique information (ID information) is generated and held inside, the URI generating unit 16 creates a URI for specifying the storage location of the scan data in the file server 40 based on the generated ID information (step 103). The URI is held inside and transmitted to the portable terminal 30 (step 104). A job is generated when the user selects a scan service from the service menu, but the ID information generated here may be used as the job ID of this job.

  When the URI acquisition unit 32 in the portable terminal 30 receives the URI transmitted from the multifunction device 10, the URI acquisition unit 32 holds and manages the URI in the information management unit 33 (step 203).

  As described above, scan data is generated when the scanner 54 scans a document by a user operation (step 105). The original is read page by page by the scanner 54. In this embodiment, a data file is generated for each page of scan data formed by the scan. In the following description, when digital data corresponding to one page among digital data (scan data) generated by reading a document consisting of a plurality of pages is indicated, the entire digital data is indicated by referring to “file” in particular. Distinguish from the case. In this embodiment, a file is a transmission unit of scan data and is sequentially transmitted by the job processing control unit 20.

  By the way, there are two types of billing: pre-billing that charges the entire amount from the IC card in advance before sending scan data and post-billing that bills the file every time the file is sent in cash. In the description, unless otherwise specified, it is assumed that a pre-charge is made. For example, the encryption unit 12 generates an encryption key based on the ID information (step 106), encrypts the scan data with this encryption key, and stores the encrypted data in the scan data management unit 11 (step 107). In the present embodiment, since one file is generated every time one page of a document is scanned, encrypted files corresponding to the number of documents are generated. If charged, a decryption key for decrypting the encrypted scan data is generated (step 108). The encryption key / decryption key may be a key that is common to all the files that constitute the scan data, or may be a different key for each file with reference to information that depends on each file.

  Subsequently, the information management unit 17 generates job information including the job ID of the job, the total number of pages of the document, the page (order) of the document corresponding to the encrypted file, and the decryption information for each encrypted file ( Step 109). The decryption information includes billed information indicating whether or not the encrypted file has been billed, a decryption key when billed, and an uncollected fee when billed. Subsequently, the job processing control unit 20 adds the job information of the file to the encrypted file and sequentially transmits the file unit (step 110).

  When transmission of scan data is started, the display processing unit 15 displays a progress display screen showing the progress of transmission illustrated in FIG. 5A on the operation panel 57. By referring to the display on the operation panel 57, the MFP 10 is operating a scan service job started from the execution date and time, and all the originals (10 pages), the originals for 4 pages (digital data) at the present time. Can be transmitted to the portable terminal 30.

  If the scan data (all encrypted files) can be transmitted normally (Y in step 111), the job processing control unit 20 deletes all the scan data stored in the scan data management unit 11, and also the information management unit 17 deletes all the information held in 17 (step 112). Then, the wireless connection processing unit 18 stops the operation of the access point 60 and disconnects the Wi-Fi connection with the mobile terminal 30 (step 113). Then, the service menu illustrated in FIG. 5C is displayed on the operation panel of the multifunction machine 10, and the initial state in which the service can be provided is restored.

  By the way, since the microwave oven used in the convenience store uses the 2.4 GHz frequency band supported by all mobile terminals such as smartphones, delays and disruptions due to radio wave interference are likely to occur during data transfer. For this reason, wireless Wi-Fi connection is more likely to be disconnected than wired connection. For this reason, when a microwave oven is used at the same time as data transfer from the multifunction device to the portable terminal, a case where the encrypted file cannot be normally transmitted from the multifunction device to the portable terminal may occur.

  When scan data (all encrypted files) cannot be transmitted normally under such a data communication environment (N in Step 111), the job processing control unit 20 displays the URI, Among the encrypted files stored in the scan data management unit 11, an encrypted file that has not yet been transmitted to the mobile terminal 30 (hereinafter also referred to as “unsent file”) and job information corresponding to the encrypted file are filed. A request to save an unsent file is sent by transmitting to the server 40 (step 114).

  When the data management unit 42 in the file server 40 acquires the information transmitted from the multi-function device 10 via the data communication processing unit 41 in response to a request from the multi-function device 10, the storage location specified by the URI is determined. The data is generated in the data storage unit 43, and the encrypted file and job information are stored in the storage location.

  Thereafter, as in step 112, the job processing control unit 20 in the multifunction device 10 stores all information related to the job stored in the multifunction device 10, specifically, an encrypted file, a key, information related to the portable terminal 30, and the like. Delete (step 115) and terminate the process. When the encrypted file cannot be transmitted normally, the display processing unit 15 illustrates the example shown in FIG. 5B during uploading of the untransmitted encrypted file to the file server 40 (step 114) and deletion of data (step 115). The displayed screen is displayed on the operation panel 57 to make the user stand by, and when these processes are completed, the service menu illustrated in FIG. 5C is displayed. As a result, the multifunction device 10 returns to the initial state in which the service can be provided.

  On the other hand, in the mobile terminal 30, after receiving and holding the URI (step 203), when the scan data acquisition unit 31 sequentially receives the encrypted file and job information transmitted from the multifunction machine 10, Since the billing has been completed for the document, the encrypted file is decrypted by the decryption unit 36 with the decryption key included in the job information and then stored in the scan data storage unit 38 (step 204). When storing in the scan data storage unit 38, job information is added. During reception of this encrypted file, the display processing unit 37 displays it on the progress display screen illustrated in FIG. 6A. By referring to the progress display screen, the user can recognize that four pages of originals (digital data) can be received at the present time among all the originals (10 pages).

  If the scan data (all encrypted files) can be received normally (Y in Step 205), the application terminates the process by causing the wireless connection processing unit 35 to disconnect the Wi-Fi connection with the multifunction machine 10 (Step S205). 212). At this time, the encrypted file and job information stored in the scan data storage unit 38 and information such as the URI held in the information management unit 33 may all be deleted.

  On the other hand, when all the encrypted files cannot be transmitted normally (N in Step 205), the display processing unit 37 displays the reception interruption notification screen illustrated in FIG. 6B on the operation panel 75. In parallel with this, the scan data acquisition unit 31 accesses the storage location specified by the URI held in the information management unit 33 and acquires the unsent file and job information stored in the storage location. (Step 206). Note that the data management unit 42 in the file server 40 may synchronize each process of storing data in the storage location by the multifunction device 10 and acquiring data by the portable terminal 30. In addition, after confirming that the data has been acquired by the mobile terminal 30, the data management unit 42 deletes the data stored in the storage location specified from the URI and the storage location itself.

  As in the present embodiment, when each encrypted file has been charged by pre-charging (Y in step 207), the scan data acquisition unit 31 corresponds to the untransmitted file acquired from the file server 40. The decryption unit 36 decrypts the decryption key using the decryption key included in the job information, and stores the decryption key 36 in the scan data storage unit 38 (step 211). Then, the wireless connection processing unit 35 in the portable terminal 30 disconnects the Wi-Fi connection with the multifunction machine 10 (step 212).

  By the way, when post-billing is performed, unsent files that have not been billed may be included in the unsent files acquired from the file server 40. Whether or not the unsent file is uncharged can be specified by referring to the decryption information included in the corresponding job information. If there is an uncharged encrypted file (N in Step 207), the display processing unit 37 Displays the charge request screen illustrated in FIG. 6C on the operation panel 75. In parallel with this, the wireless connection processing unit 35 establishes a Wi-Fi connection to the access point 60 of the multifunction machine 10 (step 208), and then the collection request unit 34 specifies an uncharged encrypted file such as a file name. Information to be collected and collection request information including the job information are generated and transmitted to the multifunction machine 10 (step 209).

  When the multifunction device 10 displaying the main menu and waiting for processing detects the collection request information transmitted from the portable terminal 30, the collection processing control unit 19 receives the collection request information (step 122). The collection processing control unit 19 refers to the received collection request information, and charges the user for an uncharged fee by displaying the charge request screen illustrated in FIG. 5D on the operation panel 57. When the billing processing unit 14 detects that the user viewing the billing billing screen or the billing request screen of the portable terminal 30 has entered the billing device 59 and paid for it (step 123), the key generation unit 13 generates a decryption key for the untransmitted file (step 124). Then, the collection processing control unit 19 transmits the generated decryption key to the portable terminal 30 (step 125).

  When the collection request unit 34 receives and acquires the decryption key (step 210), the decryption unit 36 decrypts the corresponding untransmitted file with the acquired corresponding decryption key and stores it in the scan data storage unit 38 ( Step 211). At this time, the decryption information included in the job information added to the unsent file to be stored is updated by including the charged information and the decryption key indicating that charging has been performed.

  According to the present embodiment, even if the Wi-Fi connection is disconnected as described above, the mobile terminal 30 continues to automatically scan document scan data that could not be received from the multifunction peripheral 10 from the file server 40. Therefore, the user of the portable terminal 30 does not need to perform any special operation for this purpose. When all the encrypted files are decrypted in this way, the display processing unit 37 displays a service completion screen indicating the end of provision of the scan service illustrated in FIG. 6D on the operation panel 75, thereby scanning the document. Notify the user that the data is ready for browsing.

  Personal information (in this example, original scan data) is stored in the multifunction device 10 installed in a store such as a convenience store, in other words, the multifunction device 10 installed in a public place and used by an unspecified number of visitors. It is not preferable for the customer to keep it in view of security, and it is not preferable that the storage device of the multi-function device 10 is kept private with personal information from the store side.

  Therefore, in the present embodiment, when the Wi-Fi connection is disconnected, unsent scan data existing in the multifunction device 10 is uploaded to the file server 40 and saved, and the scan service in the multifunction device 10 is used. All the data related to the user who was doing it was deleted from the multifunction machine 10. Since the file server 40 transmits the scan data for the original that could not be transmitted to the portable terminal 30 as described above, the user does not need to perform the original scan operation again.

  In the embodiment described above, the unsent data in the multifunction device 10 is uploaded to the file server 40 when the Wi-Fi connection is disconnected using the scan service as an example. Although a series of processes for causing the mobile terminal 30 to acquire the remaining data has been described, the present invention may be applied to other services that perform data transmission, not the scan data service. Further, the terminal device 30 transmits the identification number of the terminal device to the multifunction device 10, and the multifunction device 10 obtains data storage location information at the time of disconnection of data transfer from the multifunction device 10 to the terminal device 30 based on this identification information. Although the configuration to be generated has been described, the application program transmits identification information for identifying an application program for functioning the scan service activated by the terminal device, instead of the identification number of the terminal device, to the multifunction device 10, and the multifunction device 10 The data storage location information may be generated based on the information for identifying the data.
