  Hereinafter, an image recording system according to the present embodiment will be described in detail with reference to the accompanying drawings. In the present embodiment, the present invention is applied to an image recording system having a multi function peripheral (MFP) having a printing function and a mobile scanner for reading an image.

[Overall configuration of image recording system]
As shown in FIG. 1, the image recording system 1 according to the present embodiment includes a mobile scanner 100 (an example of a portable terminal) and an MFP 200 (an example of an image recording apparatus). The mobile scanner 100 has a supply port 100a and a discharge port 100b for the printing paper P, and conveys the paper P supplied from the supply port 100a toward the discharge port 100b. The mobile scanner 100 reads the image recorded on the paper P while conveying the paper P in this way, and generates image data corresponding to the read image. The MFP 200 has both a printing function for recording an image on printing paper or the like based on image data and a scanner function for reading an image formed on the printing paper or the like.

  MFP 200 may be capable of color printing or monochrome only. In this embodiment, it is assumed that color printing is possible. Also, the printing method may be an electrophotographic method or an ink jet method. The mobile scanner 100 and the MFP 200 may be capable of color reading or only for monochrome reading. In this embodiment, it is assumed that color reading is possible. Also, the reading mechanism may be a CCD or CIS.

  The mobile scanner 100 and the MFP 200 can directly transmit and receive data by wireless communication (NFC method and Wi-Fi direct method: described later). In the image recording system 1, image data relating to an image read by the mobile scanner 100 is transmitted to the MFP 200, and an image is recorded on a print sheet or the like on the MFP 200 side based on the image data. This process will be described in detail later.

[MFP configuration]
Next, a schematic configuration of the MFP 200 will be described. As shown in FIG. 2, the MFP 200 includes a printing unit (recording unit) 10 that prints an image on a sheet, a scanner 11 that reads an image of a document, and an operation panel 40 that displays an operation status and accepts an input operation by a user. A FAX interface 36, an NFC interface 37 (first image recording device side communication means), a wireless LAN interface 38 (second image communication device side communication means), and a control unit 30 (image recording device) for controlling these components. Device side control means).

  The FAX interface 36 is an interface that enables communication with an external device connected to a public line. The MFP 200 receives data transmitted from an external device via the FAX interface 36. Further, the MFP 200 transmits data to the external device via the FAX interface 36.

  The NFC interface 37 is an interface that enables NFC wireless communication (first wireless communication) based on the international standard of ISO / IEC21481 or ISO / IEC18092. The NFC method has a relatively low communication speed and a relatively short communication distance, but the power consumption required for data transmission is small. The MFP 200 transmits / receives data to / from an external device via the NFC interface 37. The NFC interface 37 establishes communication with other devices having an interface for NFC wireless communication (hereinafter referred to as NFC communication) and monitors the communication state. The NFC interface 37 can output a connection status signal indicating a communication state with another device. This connection status signal indicates that communication has been established with another device, or that once established communication has been disconnected.

  The NFC interface 37 emits a signal when the MFP 200 is in a power ON state. The NFC interface 37 can detect other devices capable of performing NFC communication by receiving a signal issued by another interface that has received this radio wave for a response. For example, the mobile scanner 100 includes an NFC interface 57 as described later. Therefore, when the user holds the mobile scanner 100 over the NFC interface 37, the NFC interface 37 detects the NFC interface 57 on the mobile scanner 100 side. Then, the NFC interface 37 and the NFC interface 57 execute processing for establishing communication according to a predetermined protocol. As a result, the MFP 200 and the mobile scanner 100 can communicate by the NFC method via the NFC interfaces 37 and 57. Note that “holding” the mobile scanner 100 over the NFC interface 37 is an operation of placing the mobile scanner 100 within the communication range of the NFC interface 37, and the mobile scanner 100 and the NFC interface 37 may not be in contact with each other.

  The wireless LAN interface 38 is an interface that enables wireless communication (second wireless communication) of the Wi-Fi direct method (WFD method) based on the IEEE 802.11 standard and its standards. The NFC method and the WFD method are different in communication method (that is, wireless communication standard), and the WFD method has a longer communication distance and higher communication speed than the NFC method. In addition, the WFD method requires relatively large power consumption for data transmission because the communication distance is long and the communication speed is high. The MFP 200 transmits / receives data to / from an external device via the wireless LAN interface 38.

  The WFD method is a communication method in which a network is constructed by a group owner device that manages a network and a client device, and data can be transferred within the network. Therefore, in order to perform data communication with an external device via the wireless LAN interface 38, it is necessary to establish wireless communication with the external device and construct a WFD network. In this embodiment, the MFP 200 becomes a group owner device when building a WFD network, and the mobile scanner 100 becomes a client device. The client device is not limited to the mobile scanner 100, and other devices can belong to the WFD network as client devices. The MFP 200 stores unique information of the client device and WFD connection information for establishing wireless communication (hereinafter referred to as WFD communication) with the client device by the WFD method. The WFD connection information includes unique information such as an SSID (Service Set IDentifier) that is an identifier for identifying the WFD network, a password, and the IP address of the MFP 200.

  The operation panel 40 has an input unit (user input interface) composed of various buttons for receiving user input, and a display for displaying messages and setting contents. The input unit can output a signal indicating a result of user input. A plurality of images can be displayed on the display. The NFC interface 37 is provided on the operation panel 40. Therefore, when the user wants to establish NFC communication between the mobile scanner 100 and the MFP 200, the user only has to place the NFC interface 57 in the mobile scanner 100 over the position where the NFC interface 37 is arranged on the operation panel 40.

The ROM 32 stores a control program for controlling the operation of each unit of the MFP 200, various settings, initial values, and the like. The RAM 33 and the flash memory 34 are used as work areas from which various control programs are read or as storage areas for temporarily storing data.

  The flash memory 34 stores WFD connection information for establishing WFD communication with the mobile scanner 100. The WFD connection information includes an SSID, a password, unique information (such as an IP address) of the MFP 200, and the like. Therefore, the flash memory 34 corresponds to the third storage means in the present invention.

The roller pair 64 is driven by a transport motor 66. The roller pair 64 transports the paper P inserted from the supply port 100a to a position facing the optical system 62 along the paper transport direction of FIG. As a result, the sheet P is directed to the roller pair 65 while being supported on the upper surface of the support plate 63. The roller pair 65 is driven by the conveying roller 67 and sends out the paper P from the roller pair 64 to the discharge unit 100b.

  The optical system 62 is disposed between the roller pairs 64 and 65 in the paper transport direction. The image sensor 61 receives light from the paper P via the optical system 62. The image sensor 61 has a plurality of photoelectric conversion elements. The photoelectric conversion element converts the applied light into an electric signal having an intensity corresponding to the intensity and the length of the applied time. These photoelectric conversion elements are arranged in the entire width direction of the paper P. Note that the width direction is a direction along the paper P and perpendicular to the paper transport direction.

  The scanner unit 56 irradiates light that has arrived from the paper P via the optical system 62 to a series of photoelectric conversion elements arranged along the width direction of the paper P at predetermined time intervals. Thereby, a series of photoelectric conversion elements generate an electric signal indicating an image for one line along the width direction of the paper P at every predetermined time. The image sensor 61 can output this electric signal every time one line is read. By sequentially executing the image reading for one line while the paper P is being conveyed in the paper conveyance direction, the image sensor 61 finally reads all the lines of the image on the paper P.

  The NFC interface 57 is an interface that enables NFC communication. Similarly to the NFC interface 37, the NFC interface 57 can output a connection status signal. The wireless LAN interface 58 is an interface that enables WFD wireless communication, as with the wireless LAN interface 38 of the MFP 200.

  The operation panel 59 has an input unit composed of various buttons for accepting user input and a screen for displaying messages and setting contents.

  The control unit 50 includes a CPU 51, a ROM 52, a RAM 53, a flash memory 54, and a timer 55. The timer 55 holds the elapsed time from the measurement start time, and can output the elapsed time to the CPU 51. The measurement start time can be set by the CPU 51 at any time. The ROM 52 stores a control program for controlling the operation of each unit of the mobile scanner 100, various settings, initial values, and the like. The RAM 53 and the flash memory 54 are used as a work area from which various control programs are read or as a storage area for temporarily storing data.

  The flash memory 54 stores WFD connection information for establishing WFD communication with the MFP 200. This WFD connection information includes an SSID, a password, unique information (such as an IP address) of the mobile scanner 100, and the like. Therefore, the flash memory 54 corresponds to the second storage means in the present invention.

  The flash memory 54 stores various applications for realizing each function of the control unit 50. The stored application includes a scanner program 71 for reading an image, an NFC communication program 72 for performing NFC communication using the NFC interface 57, and a wireless LAN for performing WFD communication using the wireless LAN interface 58. A communication program 73 and an image transmission program 74 for transmitting image data to the MFP 200 are included.

  Further, the flash memory 54 stores image data relating to the image read by the scanner unit 56. The image data is stored in the flash memory 54 while being associated with a file name for identifying the file based on a predetermined file format. Therefore, the flash memory 54 corresponds to the first storage means in the present invention.

  The image reading process based on the scanner program 71 is started by the control unit 50 when a predetermined user input is received by the operation panel 59. The scanner program 71 controls the imaging unit 61 and the conveyance motors 66 and 67 to cause the control unit 50 to function so that the scanner unit 56 reads an image formed on the paper P. Further, the scanner program 71 causes the control unit 50 to function so as to generate image data indicating a read image based on an electrical signal indicating an image generated by the image sensor 61.

  The scanner program 71 can cause the control unit 50 to function so as to generate image data for each line based on the electrical signal for one line generated in the image sensor 61. Image data relating to the read image (read image data) is stored in the flash memory 54 as one file for each image. When reading of an image is started, a storage area relating to a new file is secured in the flash memory 54. Each time an image for one line is read, image data for one line is added to the storage area related to the file. When reading is completed for all lines, the read image data is stored in the flash memory 54 as one file related to the image data for all lines. The flash memory 54 can store a plurality of files related to a plurality of read images.

  The CPU 51 processes signals and data output from each unit such as the scanner unit 56 and the operation panel 59 in accordance with each unit control program read from the ROM 52, and stores the processing result in the RAM 53 or the flash memory 54. The operation of each part of 100 is controlled. Further, the CPU 51 executes various processes based on the application stored in the flash memory 54. Thereby, various functions of the control unit 50 are realized.

This determination is performed based on the connection status information output from the NFC interface 57. If it determines with not having established (S1, No), the control part 50 will repeat the process of S1. If it determines with having established (S1, Yes), the control part 50 will start the time measurement using the timer 55 (S2). The time measurement start time point is set to a time point immediately after the NFC communication with the MFP 200 is established.

  Next, the control unit 50 transmits device information of the mobile scanner 100, specification information related to communication means, and the like to the MFP 200 by NFC communication (S3).

  Next, the control unit 50 determines whether image reading (scanning) has been started (S5). If it is determined that image reading has not started (S5, No), the control unit 50 acquires the elapsed time from the measurement start time (S2) held by the timer 55, and this elapsed time exceeds a predetermined time. It is determined whether or not (S6). When it is determined that the elapsed time does not exceed the predetermined time (S6, No), the control unit 50 determines whether the NFC communication once established with the MFP 200 is disconnected (S7). The control unit 50 determines whether the NFC communication is disconnected based on the connection status information output from the NFC interface 57 (the same applies hereinafter). If it is determined that NFC communication with the MFP 200 is disconnected (S7, Yes), the control unit 50 ends a series of processes based on the image transmission program 74. If it is determined that NFC communication with the MFP 200 is not disconnected (S7, No), the control unit 50 returns to the process of S5.

  When it is determined in S6 that the elapsed time exceeds the predetermined time (S6, Yes), the control unit 50 determines whether the image data that has been read (scanned) is stored in the flash memory 54 or not. Determine (S8). If it determines with having memorize | stored (S8, Yes), the control part 50 will move to the process of S20 of FIG. 6 (after-mentioned). If it determines with it not being memorize | stored (S8, No), the control part 50 will return to the process of S5.

  If it is determined in S5 that image reading has been started (S5, Yes), the control unit 50 transmits to the MFP 200 a real-time reception command instructing reception of image data relating to the image being read (S9). ). And the control part 50 performs the real-time transmission process which transmits the image data which concerns on the image under reading in parallel with reading as follows (S10-S17).

  The control unit 50 controls the scanner unit 56 so as to read only one line of the image recorded on the paper P (S10). Next, the control unit 50 stores the image data related to the read image for one line in the flash memory 54 (S11). As a result, image data relating to the image being read is stored in the flash memory 54 line by line. Next, the control unit 50 determines whether the NFC communication with the MFP 200 is disconnected (S12). And if it determines with having cut | disconnected (S12, Yes), the control part 50 will move to the process of S14. If it is determined that it is not disconnected (S12, No), the control unit 50 transmits the image data for one line just read in S10 to the MFP 200 by NFC communication (S13), and then the process proceeds to S14.

  In S14, the control unit 50 determines whether images for all lines have been read. If it is determined that the images for all lines have not been read (S14, No), the control unit 50 returns to the process of S10. If it takes a relatively long time to transmit image data for one line in S13, the processes of S14 and S10 may be executed one after another until the data transmission is completed. According to this, since data transmission and image reading are performed at the same time, the entire processing time is shortened as compared with the case where data is transmitted after the reading is completed. If it determines with having read the image for all the lines in S14 (S14, Yes), the control part 50 will move to the process of S15. It should be noted that the image data for all lines is stored in the flash memory 54 by reading the image for all lines.

  In S15, the control unit 50 determines whether or not the NFC communication with the MFP 200 is disconnected during the series of processes of S10 to S14 (S15). If it is determined that it is not cut (S15, No), the control unit 50 ends a series of processes based on the image transmission program 74. If it is determined that the connection has been disconnected (S15, Yes), the control unit 50 establishes WFD communication based on the WFD connection information transmitted to and received from the MFP 200 in S4 (S16). Then, the control unit 50 transmits the untransmitted image data (untransmitted data) to the MFP 200 through the WFD communication due to the NFC communication being disconnected during the series of processes of S10 to S14 (S17). ).

  Specifically, control unit 50 transmits at least an untransmitted portion of image data stored in flash memory 54 to MFP 200. Here, the untransmitted portion is a remaining portion obtained by excluding data transmitted to the MFP 200 from the data for all lines stored in the flash memory 54 until the time of disconnection. However, in consideration of the fact that it may not always be clear whether the data transmitted immediately before disconnection is reliably received by the MFP 200, in S17, in addition to the untransmitted portion, the data transmitted immediately before disconnection. May be transmitted to the MFP 200. The control unit 50 ends the series of processes based on the image transmission program 74 after S17.

  Next, the case where the process moves from S8 in FIG. 5 to S20 in FIG. 6 will be described. The control unit 50 transmits to the MFP 200 a stored image reception command that instructs to receive the stored image that has been read (S20). Next, the control unit 50 transmits file information (image identification information) indicating a file name and the like related to the read image data stored in the flash memory 54 to the MFP 200 by NFC communication (S21). The file information may be information for identifying each image such as a file name, and may include image data indicating a thumbnail image (an image obtained by reducing the original image) related to each image. Each time S21 is executed, file information relating to one image is transmitted.

  Next, the control unit 50 determines whether or not the NFC communication with the MFP 200 is disconnected (S22). If it is determined that the file is not disconnected, the control unit 50 determines whether or not the file information has been transmitted for all files (S23). If it determines with not transmitting (S23, No), the control part 50 will return to S21. If it determines with having transmitted, the control part 50 will move to the process of S24. As described above, when the NFC communication is not disconnected during the transmission of the file information, the control unit 50 transmits all the file information to the MFP 200 through the NFC communication.

  On the other hand, when it is determined in S22 that the NFC communication with the MFP 200 has been disconnected (S22, Yes), the control unit 50 establishes WFD communication based on the WFD connection information transmitted to and received from the MFP 200 in S4. (S31). Then, the control unit 50 transmits the file information (untransmitted data) that has not been transmitted due to the disconnection of the NFC communication during the series of processes of S21 to S23 to the MFP 200 by WFD communication (S32). ). The untransmitted file information is a portion that has not been transmitted in S21 among the file information related to the plurality of read images. Again, in consideration of the fact that it may not always be clear whether the partial file information transmitted immediately before disconnection has been received by the MFP 200, in S32, in addition to the untransmitted portion, A part of the file information transmitted immediately before may be transmitted to the MFP 200.

  As described later, the MFP 200 selects a file to be transmitted from the mobile scanner 100 based on the file information transmitted in S21 and S32. Then, since the file transmission request related to the selected file is transmitted from the MFP 200 by WFD communication, the control unit 50 receives this (S33). The control unit 50 acquires image data corresponding to the received file transmission request from the flash memory 54, and transmits it to the MFP 200 by WFD communication (S34). Then, the control unit 50 ends a series of processes based on the image transmission program 74.

  The process returns to the case where all file information is transmitted to the MFP 200 by NFC communication again. When all the file information is transmitted to MFP 200 by NFC communication (S23, Yes), control unit 50 determines whether NFC communication with MFP 200 has been disconnected (S24). If it is determined that the connection has been disconnected, the control unit 50 establishes WFD communication based on the WFD connection information transmitted / received to / from the MFP 200 in S4 (S29). Then, the control unit 50 proceeds to the process of S33. In the processing after S33, as described above, the control unit 50 receives a file transmission request through the WFD communication established in S29, and transmits image data corresponding to the request to the MFP 200 (S33, S34).

  If it is determined in S24 that the NFC communication is not disconnected (S24, No), the control unit 50 receives the file transmission request transmitted from the MFP 200 through the NFC communication (S25). Then, the control unit 50 acquires image data corresponding to the file transmission request from the flash memory 54, and partially transmits the image data to the MFP 200 by NFC communication (S26). Next, the control unit 50 determines whether or not NFC communication with the MFP 200 is disconnected (S27). If it is determined that the NFC communication is not disconnected (No at S27), the control unit 50 determines whether all of the image data corresponding to the file transmission request has been transmitted (S28). If it determines with not transmitting (S28, No), the control part 50 will return to the process of S26. In S <b> 26, control unit 50 transmits the remaining image data to MFP 200 by NFC communication part by part. As described above, while the NFC communication is established, the control unit 50 continues to transmit the image data to the MFP 200 by the NFC communication. If it is determined that all the image data has been transmitted (S28, Yes), the control unit 50 ends a series of processes based on the image transmission program 74.

  On the other hand, if it is determined in S27 that the NFC communication has been disconnected (S27, Yes), the control unit 50 establishes WFD communication based on the WFD connection information transmitted to and received from the MFP 200 in S4 (S35). Then, the control unit 50 transmits the untransmitted image data (untransmitted data) to the MFP 200 by the WFD communication because the NFC communication is disconnected during the series of processes of S26 to S28 (S36). ). Here, the untransmitted portion is the remaining portion of the image data corresponding to the file transmission request, excluding data transmitted to the MFP 200 until the time of disconnection. However, in S36 as well as S17, a part of the data transmitted immediately before the disconnection may be transmitted to the MFP 200 in addition to the untransmitted portion. The control part 50 complete | finishes a series of processes based on the image transmission program 74 after S36.

  As described above, data (transmission data in the present invention) transmitted from the mobile scanner 100 to the MFP 200 is image data being read in the real-time transmission process, and relates to a read image in the processes after S20. File information and image data. In any case, first, data transmission is started by NFC communication, and if the NFC communication is cut off in the middle, all remaining (untransmitted) portions are transmitted by WFD communication. As a result, the transmission of the image data to be printed is reliably executed.

[Processing on the MFP side]
Next, processing executed by the control unit 30 in accordance with the image reception program 43 will be described with reference to FIGS. First, the control unit 30 determines whether NFC communication has been established with the mobile scanner 100 (S40 in FIG. 7). This determination is made based on connection status information output from the NFC interface 37. If it determines with not having established (S40, No), the control part 30 will repeat the process of S40. If it determines with having established (S40, Yes), the control part 30 will start the time measurement using the timer 35 (S41). The time measurement start time is set to a time immediately after NFC communication with the mobile scanner 100 is established.

  Next, the control unit 30 receives the specification information transmitted from the mobile scanner 100 by NFC communication (S42). Next, the control unit 30 transmits / receives WFD connection information to / from the mobile scanner 100 by NFC communication (S43). As a result, the control unit 30 transmits the unique information related to the MFP 200 to the mobile scanner 100 and receives the specific information related to the mobile scanner 100 transmitted from the mobile scanner 100.

  Next, the control unit 30 determines whether or not a real-time reception command transmitted from the mobile scanner 100 has been received (S44). If it is determined that the real-time reception command has not been received (S44, No), the control unit 30 acquires the elapsed time from the measurement start time (S41) held by the timer 35, and the elapsed time exceeds a predetermined time. It is determined whether it has been exceeded (S48). When it is determined that the elapsed time does not exceed the predetermined time (S48, No), the control unit 30 determines whether the NFC communication once established with the mobile scanner 100 is disconnected (S49). . The control unit 30 determines whether or not the NFC communication is disconnected based on the connection status information output from the NFC interface 37 (hereinafter the same). If it is determined that NFC communication with the mobile scanner 100 is disconnected (S49, Yes), the control unit 30 ends a series of processes based on the image reception program 43. If it is determined that NFC communication with the mobile scanner 100 is not disconnected (S49, No), the control unit 30 returns to the process of S44.

  When it is determined in S48 that the elapsed time exceeds the predetermined time (S48, Yes), the control unit 30 determines whether or not a stored image reception command transmitted from the mobile scanner 100 has been received (S50). . If it is determined that the stored image reception command has been received, the control unit 30 proceeds to the process of S60 in FIG. 8 (described later). If it determines with the preservation | save image reception command not being received (S50, No), the control part 30 will return to the process of S44.

  On the other hand, if it is determined in S44 that a real-time reception command has been received (S44, Yes), the control unit 30 receives image data transmitted by the mobile scanner 100 in parallel with image reading in accordance with the real-time reception command. Real-time reception processing is executed (S45-S47, S51, S52). First, the control unit 30 determines whether NFC communication with the mobile scanner 100 is disconnected (S45). If it is determined that it is not disconnected (S45, No), the control unit 50 receives image data for one line transmitted from the mobile scanner 100 through NFC communication (S46). The control unit 30 stores the received image data in the flash memory 34. Then, the control unit 30 determines whether or not image data has been received for all lines (S47). If it is determined that the image data has not been received (S47, No), the process returns to S45. If it determines with having received (S47, Yes), the control part 30 will perform a printing process based on the received image data (S53). That is, the control unit 30 controls the printing unit 10 to record an image related to the image data stored in the flash memory 34 on a printing paper or the like. Then, the control unit 30 ends a series of processes based on the image reception program 43.

  On the other hand, when it is determined in S45 that the NFC communication with the mobile scanner 100 is disconnected (S45, Yes), the control unit 30 is based on the WFD connection information transmitted and received with the mobile scanner 100 in S43. WFD communication is established (S51). Then, the control unit 30 receives data including at least the remaining image data that has been transmitted from the mobile scanner 100 and has not been transmitted due to the disconnection of NFC communication (S52). As described above, the data received in S52 may include a part of data transmitted by the mobile scanner 100 immediately before disconnection, other than untransmitted image data. The control unit 30 stores the received image data in the flash memory 34. Then, the control unit 30 executes a printing process based on the received image data (S53), and ends a series of processes based on the image reception program 43.

  Next, the case where the process proceeds from S50 of FIG. 7 to S60 of FIG. 8 will be described. The control unit 30 receives file information transmitted from the mobile scanner 100 by NFC communication (S60). Next, the control unit 30 determines whether or not NFC communication with the mobile scanner 100 is disconnected (S61). If it is determined that the file is not disconnected, the control unit 30 determines whether file information has been received for all files (S62). If it determines with not having received (S62, No), the control part 30 will return to the process of S60. If it determines with having received, the control part 30 will move to the process of S63. As described above, when the NFC communication is not disconnected while receiving the file information, the control unit 30 receives all the file information through the NFC communication.

  On the other hand, when it is determined in S61 that the NFC communication with the mobile scanner 100 has been disconnected (S61, Yes), the control unit 30 performs WFD based on the WFD connection information transmitted to and received from the mobile scanner 100 in S43. Communication is established (S72). Since the file information including at least the file information that has not been transmitted due to the disconnection of the NFC communication during the series of processes of S60 to S62 is transmitted from the mobile scanner 100 by the WFD communication, the control unit 30 This is received (S73). As described above, the file information received in S73 may include a part of the file information transmitted immediately before the disconnection by the mobile scanner 100 in addition to the untransmitted file information.

  Next, the control unit 30 generates a file transmission request for requesting the mobile scanner 100 to transmit a file based on the file information received in S60 and S73 (S74). Specifically, first, the control unit 30 causes the operation panel 40 to display a selection image corresponding to each file indicated by the file information on the display. The selection image is an image indicating information for identifying a file such as a file name. As the selection image, a thumbnail image related to the image corresponding to the file name may be used. Then, based on the information displayed on the display, the user performs input for designating a file via the input unit. In response to this, the control unit 30 selects a file designated by the user as a transmission request target based on the user input received by the input unit. Then, a file transmission request related to the selected file is generated. The file transmission request includes information for identifying a file to be transmitted. Such information may be the file name itself or other identification information.

  Then, the control unit 30 transmits a file transmission request to the mobile scanner 100 by WFD communication (S75). In response to this, the mobile scanner 100 transmits image data corresponding to the file transmission request by WFD communication. The control unit 30 receives the image data transmitted from the mobile scanner 100 by WFD communication (S76). The control unit 30 stores the received image data in the flash memory 34. Then, the control unit 30 executes a printing process based on the received image data (S71), and ends a series of processes based on the image reception program 43. The process of S71 is the same as that of S53.

  The process returns to the case where all file information is received again by NFC communication. When all the file information is received by NFC communication (S62, Yes), the control unit 30 generates a file transmission request based on the received file information (S63). This process is the same as S74. Next, the control unit 30 determines whether or not the NFC communication with the mobile scanner 100 is disconnected (S64). If it determines with having cut | disconnected, the control part 30 will establish WFD communication based on the WFD connection information transmitted / received between the mobile scanners 100 in S43 (S77). Then, the control unit 30 proceeds to the process of S75. In the processing after S74, the control unit 30 transmits the file transmission request generated in S63 to the mobile scanner 100 by the WFD communication established in S77 and receives the image data transmitted from the mobile scanner 100. (S75, S76).

  On the other hand, if it is determined in S64 that the NFC communication is not disconnected (S64, No), the control unit 30 transmits the file transmission request generated in S63 to the mobile scanner 100 by NFC communication (S65). Then, the control unit 30 receives the image data transmitted by the mobile scanner 100 in response to the file transmission request by NFC communication (S66). Since the mobile scanner 100 transmits the image data part by part, in step S66, the mobile scanner 100 sequentially receives the data. The control unit 30 stores the received image data in the flash memory 34. Next, the control unit 30 determines whether or not the NFC communication with the mobile scanner 100 is disconnected (S67). If it is determined that the NFC communication is not disconnected (S67, No), the control unit 30 determines whether all of the image data corresponding to the file transmission request has been received (S70). If it determines with not having received (S70, No), the control part 30 will return to the process of S66. Thus, while the NFC communication is established, the control unit 30 continues to receive the image data transmitted from the mobile scanner 100 through the NFC communication. If it is determined that all the image data has been transmitted (S70, Yes), the control unit 30 executes a printing process based on the received image data (S71), and performs a series of processes based on the image reception program 43. finish.

  On the other hand, if it is determined in S67 that the NFC communication has been disconnected (S67, Yes), the control unit 30 establishes WFD communication based on the WFD connection information transmitted to and received from the mobile scanner 100 in S43 (S68). Data including at least image data (untransmitted data) that has not been transmitted due to the disconnection of NFC communication during the series of processes of S66, S67, and S70 is transmitted from the mobile scanner 100 by WFD communication. Therefore, the control unit 30 receives this (S69). As described above, the data received in S69 may include a part of the image data transmitted immediately before the disconnection by the mobile scanner 100 in addition to the image data that has not been transmitted. The control unit 30 stores the received image data in the flash memory 34. Then, the control unit 30 executes a printing process based on the received image data (S71), and ends a series of processes based on the image reception program 43.

[Example of operation by mobile scanner and MFP]
Hereinafter, an example of the flow of operations performed by the mobile scanner 100 and the MFP 200 according to the flow of FIGS. 5 to 8 will be described with reference to the sequence diagrams of FIGS. 9 and 10. 9 and 10 correspond to different examples.

  First, it demonstrates along FIG. When the user holds the mobile scanner 100 over the NFC interface 37 of the MFP 200, NFC communication is established between the mobile scanner 100 and the MFP 200 (the mobile scanner 100 side performs the processing of S1 in FIG. 5, and the MFP 200 side performs the processing of S40 in FIG. Processing; hereinafter simply described as “S1, S40” and the like). Thereby, time measurement is started in the mobile scanner 100 (S2). Then, specification information is transmitted from the mobile scanner 100 to the MFP 200 (S3, S42), and WFD connection information is transmitted / received between them (S3, S42).

  When the user performs a predetermined user input via the operation panel 59 within a predetermined time after the time measurement is started in S2, scanning of the image is started (S5, Yes). As a result, a real-time reception command is transmitted from the mobile scanner 100 to the MFP 200 (S9, S44). Each time the mobile scanner 100 reads an image, the image data relating to the image being read is transmitted line by line from the mobile scanner 100 to the MFP 200 by NFC communication (S13, S46). For example, it is assumed that the user moves the mobile scanner 100 away from the MFP 200 immediately after the 1st to nth line (n: natural number) image data is transmitted. As a result, NFC communication is disconnected between the mobile scanner 100 and the MFP 200.

  Even if the NFC communication is disconnected, the mobile scanner 100 continues to scan the image, but the image data is not transmitted (S12, Yes → S14, No). When the mobile scanner 100 completes image scanning for all lines (S14, Yes), WFD communication is established between the mobile scanner 100 and the MFP 200 (S16, S51). Then, for example, image data from the nth line to the last line is transmitted from the mobile scanner 100 to the MFP 200 by WFD communication (S17, S52). In NFC communication, image data up to the n-th line has already been transmitted. Therefore, the untransmitted part is from the (n + 1) th line to the last line. However, considering that it is not clear whether the MFP 200 has received the data reliably, the n-th line image data is also sent together with the untransmitted portion. Then, the MFP 200 executes print processing based on the received image data (S53).

  Next, a description will be given with reference to FIG. The process from when the user holds the mobile scanner 100 over the NFC interface 37 until the WFD connection information is transmitted / received (S4, S43) is the same as in FIG. On the other hand, in FIG. 10, it is assumed that scanning of an image is not started within a predetermined time after the time measurement is started in S2 (S5, No → S6, Yes). Then, it is assumed that scanned image data in the mobile scanner 100 is stored in the flash memory 54 (S8, Yes).

  In this case, a stored image reception command is transmitted from the mobile scanner 100 to the MFP 200 (S20, S50). Next, file information is transmitted from the mobile scanner 100 to the MFP 200 (S21, S60). Here, if the NFC communication is not disconnected while the file information is transmitted, all file information is transmitted from the mobile scanner 100 to the MFP 200 by NFC communication (S21 to S23, S60 to S62). Next, in the MFP 200, a file transmission request is generated based on the file information transmitted from the mobile scanner 100 (S63).

  Next, part of the image data corresponding to the file transmission request is transmitted from the mobile scanner 100 to the MFP 200 by NFC communication (S26, S66). Assume that the user separates mobile scanner 100 from MFP 200 before all the image data is transmitted. Thereby, when the NFC communication is disconnected, WFD communication is established between the mobile scanner 100 and the MFP 200 (S35, S68). Then, from the mobile scanner 100 to the MFP 200, an untransmitted portion and a portion (+ α portion) transmitted immediately before disconnection of all image data are transmitted by WFD communication (S36, S69). As in the case of FIG. 9, this + α portion is a portion that is sent considering that it is not clear whether or not the MFP 200 has surely received it. Then, the MFP 200 executes print processing based on the received image data (S71).

  In the example of FIG. 9, as described above, it is assumed that scanning is started after NFC communication is established between the mobile scanner 100 and the MFP 200. However, after scanning is started in the mobile scanner 100, NFC communication may be established by the user holding the mobile scanner 100 over the NFC interface 37. Also in this case, since it is determined that the scan is started in the determination of whether or not the scan is started (S5), the real-time transmission process (S10 to S10) that transmits the image data in parallel with the reading of the image. S17) is executed.

  In the example of FIG. 10, as described above, when NFC communication is disconnected while image data is being transmitted by NFC communication, the remaining image data is transmitted by WFD communication. However, as shown in FIGS. 6 and 8, even when the NFC communication is disconnected while the file information is being transmitted by the NFC communication, the remaining file information is transmitted by the WFD communication (S31, S32, S72, S73). .

  Further, both FIG. 9 and FIG. 10 are examples in which the user disconnects the NFC communication by moving the mobile scanner 100 away from the MFP 200 during the data transmission by the NFC communication. However, when the user desires to continue data transmission by NFC communication, the state in which the mobile scanner 100 is held over the NFC interface 37 of the MFP 200 may be maintained. As long as this state is maintained, data transmission by NFC communication continues.

  According to the present embodiment described above, after the NFC communication is established, the user may hold the mobile scanner 100 as it is if the user wants to continue transmitting data by the NFC communication. On the other hand, to transmit data by WFD communication, mobile scanner 100 may be separated from MFP 200 and NFC communication may be disconnected. As a result, the user can freely select NFC communication with low communication speed but low power consumption, or WFD communication with high communication speed but high power consumption.

  When NFC communication is established, WFD connection information is first transmitted and received between the mobile scanner 100 and the MFP 200 before transmitting file information, image data, and the like (S4, S43). Therefore, WFD communication can be established whenever NFC communication is disconnected thereafter.

  If scanning of an image is started in the mobile scanner 100 within a predetermined time after the NFC communication is established, image data for one line is transmitted to the MFP 200 in parallel with image reading for one line. (S10 to S14, S45 to S47). As described above, since the image data is sequentially transmitted in parallel with the reading of the image, the entire processing time is shorter than when the data is transmitted after the reading is completed.

  On the other hand, if the NFC communication is disconnected during the scan, the remaining data is transmitted from the mobile scanner 100 to the MFP 200 by WFD communication for the time being (S10 to S17, S45, S51, S52). Therefore, power is not consumed at the same time for both data communication and image reading by WFD communication with relatively large power consumption. For this reason, it is suppressed that power consumption becomes excessive temporarily. In addition, since WFD communication has a high communication speed, the time required for transmission is relatively short. For this reason, even if the remaining image data are transmitted together after the image reading is completed, it is difficult for the user to feel the length of the standby time. In addition, when image data is transmitted collectively after reading is completed, the time during which WFD communication is performed can be shortened. Therefore, it is possible to reduce power consumption compared to the case where image data is transmitted by WFD communication in parallel with image reading for one line.

  Further, when the scanned image data stored in the mobile scanner 100 is transmitted to the MFP 200, file information related to the image data is transmitted to the MFP 200 prior to transmission of the image data. When the user designates a file via the operation panel 40 of the MFP 200, a file transmission request relating to the designated file is transmitted from the MFP 200 to the mobile scanner 100. In response to this, the image data corresponding to the file transmission request is transmitted from the mobile scanner 100 to the MFP 200. Therefore, the user can select a necessary file using the interface of the MFP 200. Further, even when there are a plurality of candidate images, only the image data related to the necessary image is transmitted, so that the time and power required for communication are suppressed.

[Modification]
Hereinafter, modified examples according to the above-described embodiment will be described. For example, in the above-described embodiment, the mobile scanner 100 is employed as an example of the mobile terminal of the present invention. However, a smartphone or the like that does not have a scanner function may be employed as the mobile terminal. In this case, image data saved in the portable terminal is transmitted from the portable terminal to the MFP 200. Such image data may be data such as photographs taken by the function of the mobile terminal, or data read from another recording medium by the mobile terminal or sent to the mobile terminal via the data communication network. There may be. In this case, real-time transmission processing for transmitting image data in parallel with image reading is not employed. Specifically, the image transmission program of the mobile terminal of the present modification is a program that causes the mobile terminal to execute the processes of S21 to S36 of FIG. 6 after the processes of S1 to S4 of FIG. The image receiving program of the MFP 200 is a program that causes the MFP 200 to execute the processes of S60 to S76 in FIG. 8 after the processes of S40 to S43 in FIG.

  In the above-described embodiment, when NFC communication is established, mutual WFD connection information is transmitted and received between the mobile scanner 100 and the MFP 200 (S4, S43). However, if one device (hereinafter referred to as device A) can be a group owner device and the other device (hereinafter referred to as device B) can be a client device, the device A in S4 and S43. The WFD connection information may be transmitted unilaterally to the device B. Even in this case, when it is desired to establish WFD communication later, based on the WFD connection information transmitted from the device A (particularly, specific information related to the device A), the device B transmits packet information to the device A by the WFD method. can do. The packet information includes unique information related to the device B as a transmission source. For this reason, after that, it becomes possible to transmit data from the device A to the device B based on the unique information related to the device B. The above condition that the device A can be a group owner device and the device B can be a client device is a condition required when the WFD method is adopted. If the communication is not the WFD method but the normal Wi-Fi method via a router, the connection information for Wi-Fi is unilaterally transferred from the device A to the device B in S4 and S43 even without the above-described conditions. May be transmitted, or conversely, Wi-Fi connection information may be transmitted unilaterally from apparatus B to apparatus A. According to the normal Wi-Fi scheme, even if there is no condition as described above, based on the connection information first transmitted from one device, the other device transmits packet information including specific information related to that device to one device. It is because it can transmit to.

  In the above-described embodiment, WFD communication is employed as the second wireless communication of the present invention. However, other communication methods such as a Bluetooth method may be employed. Two or more communication methods may be employed. In this case, when the specification information is transmitted and received in S3 and S42, it is preferable to transmit and receive information indicating what kind of communication means each other has. This makes it possible to select which communication means is used to transmit the remaining data when NFC communication is later disconnected.

  In the above-described embodiment, when image data is transmitted from the mobile scanner 100 to the MFP 200, the MFP 200 executes print processing as it is based on the image data (S53, S71). However, the MFP 200 may be configured to execute the printing process only when a print command instructing printing is transmitted from the mobile scanner 100 together with the image data. In this case, whether or not a print command is transmitted may be determined based on whether or not the user has instructed execution of printing via the operation panel 59 in the mobile scanner 100. Alternatively, the MFP 200 may be configured so that the printing process is executed only when the user instructs the execution of printing via the operation panel 40 in advance in the MFP 200.

  In addition, various processes according to the above-described embodiments may be executed by a single CPU, a plurality of CPUs, hardware such as an ASIC, or a combination thereof. Further, the CPU may perform some processes according to the OS. The various processes according to the above-described embodiment can be realized in various modes such as a recording medium or a method recording a program for executing the processes. In the above-described embodiment, the ROM, RAM, and flash memory are properly used according to the data to be stored. However, the mode for properly using these storage devices is not limited to the mode in the above-described embodiment. For example, in the above-described embodiment, various programs stored in the flash memory may be stored in the ROM. The reverse is also possible. Further, the storage destination for temporarily storing data is not limited to the above-described embodiment, and may be a RAM or a flash memory.

  In the above-described embodiment, determination of establishment or disconnection of NFC communication is made based on connection status information output from the NFC interface 37 or 57. However, it may be determined by other methods. For example, in the process in which the control unit 30 or 50 manages a communication session based on the NFC communication program 41 or 72, when it is detected that data has not been received through the NFC interface 37 or 57 for a predetermined time or more. The NFC communication may be determined to have been disconnected.
