  The present invention relates to an image processing system including an image processing device such as an MFP (Multi Function Peripherals) which is a multifunction digital multifunction peripheral, and a mobile terminal device such as a smartphone or a tablet terminal capable of remotely operating the image processing device, The present invention relates to a connection control program for an image processing device and a portable terminal device.

  In recent years, portable terminal devices such as smartphones and tablet terminals can store digitized documents, and can browse and edit documents regardless of time and place. In addition, a file edited by the portable terminal device can be transmitted to an image processing apparatus such as the MFP, and the image processing apparatus can execute processing such as printing or saving. Furthermore, a file composed of image data of a document read by the scanner unit of the image processing apparatus can be transmitted to the mobile terminal device, and can be edited by the mobile terminal device.

  However, it is necessary to operate the mobile terminal device and the image processing device separately, and there is a problem that the operation becomes complicated.

  Therefore, recently, an operation screen on the side of the image processing apparatus for using the function of the image processing apparatus is displayed as a remote screen on the display unit of the mobile terminal device wirelessly connected to the image processing device, and image processing is performed from the mobile terminal device. There has been proposed a cooperation system between an image processing apparatus and a portable terminal device that enables the apparatus to be operated in cooperation. In this system, the remote screen on the image processing device side displayed on the display unit of the mobile terminal device is displayed based on the screen data transmitted from the image processing device.

  That is, information indicating that an operation has been performed on the remote screen is transmitted from the portable terminal device to the image processing device, and the image processing device creates the next screen data based on this information, and this screen data is carried by the portable device. The data is transmitted to the terminal device, and the mobile terminal device updates and displays the remote screen based on this screen data.

  However, in such a system, when wireless communication between the mobile terminal device and the image processing device is interrupted while the user operates the image processing device with the mobile terminal device, there is a problem as described later.

  In Patent Document 1, a copy machine that can implement a plurality of functions including a network display function that obtains predetermined information from a device on a LAN and displays information based on the information is displayed via an operation screen. An operation unit that accepts input and displays a display screen related to each function, and when the input operation through the operation unit has not been performed for a predetermined period, the set value of the predetermined function is reset. A technique is disclosed in which an operation screen related to a predetermined function is displayed on an operation unit while being set to an initial value.

  Further, in Patent Document 2, when an authentication code is input by an input unit for a predetermined period after the end of the user authentication state is instructed, a comparison with the authentication code stored in the storage unit is made. Based on this, a technique for setting the user authentication state is disclosed.

  FIG. 4 is a diagram for explaining operations of the MFP 1 and the portable terminal 2 during remote operation.

  When the user of the mobile terminal 2 sets the mobile terminal 2 to the remote mode and makes a request for acquiring screen data by wireless communication to the MFP 1, the MFP 1 displays display data for the initial operation screen displayed on the display unit 134. The data is transmitted to the mobile terminal 2, and the mobile terminal 2 receives the display data for the operation screen, and displays an operation screen for operating the MFP 1 on the display unit 220 as a remote screen based on the data.

  When the user of the mobile terminal 2 performs a touch operation on a predetermined button or the like on the remote screen (step S01), the CPU 201 of the mobile terminal 2 detects the coordinates of the touch position (step S02), determines the type of gesture operation, and determines the MFP1. Is converted to the coordinates of the touch panel (step S03). Then, the mobile terminal 4 transmits a touch event including the coordinates of the touch position to the MFP 1 (step S04).

  Upon receiving the touch event received from the portable terminal 1 (step S05), the MFP 1 analyzes the touch event process, that is, the coordinates of the touch position (step S06), and determines what operation screen is displayed in the internal process (step S07). ), An operation screen to be drawn on the display unit is created by the image creation process. The operation screen is created by dividing a part image constituting the screen, such as a background image of the screen, a plurality of operation buttons, etc., and storing the operation screen in accordance with the coordinates of the touch position.

  Further, when there is another mobile terminal 2 that is already connected to the same MFP 1 when the mobile terminal 2 is connected to the MFP 1, the display unit 220 of the mobile terminal 2 waits for an order as shown in FIG. A screen D6 is displayed. On this order waiting screen D6, the number of connected users, a setting button indicating whether to notify when the order waiting is canceled, a disconnection time setting field indicating a time for waiting for the order, a connection time with the MFP 1, and the like are displayed. .

  Next, an operation when wireless communication is interrupted after wireless connection between the plurality of portable terminals 2 and the MFP 1 will be described.

  In this embodiment, the CPU 1 of the MFP 1 has a function of measuring the distance from the portable terminal 2. The method for measuring the distance to the mobile terminal 2 is not particularly limited. For example, the mobile terminal 2 is equipped with a global positioning system (GPS) function, and the MFP 1 obtains the position information of the mobile terminal 2 based on the function. A method of measuring the distance from the portable terminal 2 from the position of the portable terminal 2 and the position of the MFP itself can be given.

  Further, as shown in FIG. 12, the distance L <b> 1 and the distance L <b> 2 are set in advance in the MFP 1 with respect to the distance between the MFP 1 and the portable terminal 2.

  The distance L1 is a limit distance (first distance) set in advance as a distance at which the user of the mobile terminal 2 can continue to operate the MFP 1, and the distance L2 is a distance at which the user of the mobile terminal 2 can immediately operate the MFP 1 As a minimum distance (second distance) smaller than the limit distance L2. The MFP 1 compares the distance to the mobile terminal 2 when the wireless communication with the mobile terminal 2 is disconnected, the limit distance L1 and the minimum distance L2, and executes the following processing according to the comparison result.

  First, as shown in FIG. 13, for example, when the user A of the mobile terminal 2a starts an application for connection of the mobile terminal 2a to connect to the MFP 1, a connection screen D2 is displayed on the display unit 220 of the mobile terminal 2a. A general login screen D1 shown in FIG. 6 is displayed on the display unit 134 of the MFP 1. In FIG. 13, the screen transition diagram shown on the side of the MFP 1 is a screen transition diagram of the display unit 134 of the MFP 1, and the screen transition diagram shown on the side of the mobile terminal 2a is the display unit of the mobile terminal 2a. FIG. The same applies to the screen transition diagrams in FIG.

  When a screen acquisition request is transmitted from the portable terminal 2a to the MFP 1 based on the operation of the user A, the general login screen D1 displayed on the MFP 1 is displayed on the display unit 220 of the portable terminal 2a. The screen is switched to the remote connection in-progress screen D5 shown in FIG. Further, after the user A logs in to the MFP 1 from the portable terminal 2a, the operation screen display data corresponding to the operation is transmitted from the MFP 1 to the portable terminal 2a. An operation screen D3) is displayed.

  When the wireless communication with the mobile terminal 2a is disconnected, the MFP 1 measures the distance to the mobile terminal 2a at the time of disconnection and compares it with the limit distance L1 and the minimum distance L2. When the wireless connection with the mobile terminal 2a is disconnected at the limit distance L1 or less and the minimum distance L2 or less, the screen D3 displayed on the mobile terminal 2a when the connection is disconnected is displayed on the display unit 134 of the MFP 1, and the mobile terminal The connection screen D2 is displayed on the display unit 220 of 2a.

  That is, when the distance from the portable terminal 2 when the wireless communication is disconnected is equal to or less than the minimum distance L2, the distance from the portable terminal 2a is small, so that the user A reaches the MFP 1 quickly and there is no big problem in terms of security. By displaying the operation screen displayed on the mobile terminal 2 on the MFP 1, the user A of the mobile terminal 2a can continue to use the MFP 1 as it is, thereby ensuring operability.

  In this case, in this embodiment, the MFP 1 sets a continuous operation waiting time proportional to the distance from the portable terminal 2a when the wireless communication is disconnected, and even if the continuous operation waiting time is exceeded, an operation by the user A of the portable terminal 2a or a portable operation is performed. When the reconnection from the terminal 2a is not performed, the MFP 1 switches the display on the display unit 134 to the general login screen D1 illustrated in FIG.

  As described above, when the user A of the portable terminal 2a does not continue the operation of the MFP 1, the operation screen displayed on the MFP 1 is switched to the general login screen D1, so that the operation screen is displayed and left. The risk that the three parties can use the MFP 1 can be eliminated.

  FIG. 14 is a diagram for explaining the operation when the wireless communication with the portable terminal 2a is disconnected in a state where the distance between the MFP 1 and the portable terminal 2a is not more than the limit distance L1 and exceeds the minimum distance L2. It is.

  The process until the wireless communication between the MFP 1 and the portable terminal 2a is disconnected is the same as in the case of FIG. When the wireless connection with the mobile terminal 2a is disconnected, the restricted login screen D7 that allows only the user A of the mobile terminal 2a to log in is displayed on the display unit 134 of the MFP 1 while maintaining the login state of the user A of the mobile terminal 2a. The connection screen D2 is displayed on the display unit 220 of the mobile terminal 2a.

  FIG. 15 shows details of the restricted login screen D7. On this restricted login screen D7, a user name input field, a password input field, and a server name input field are displayed together with a message indicating that only the currently connected user A can log in. User A enters data in each input field. When the login button is pressed, authentication is performed and the MFP 1 can be logged in. Even if a user other than the user A logs in using the restricted login screen D7, the authentication fails and the user cannot log in.

  Further, the MFP 1 sets a continuous operation waiting time proportional to the distance from the portable terminal 2a when the wireless communication is disconnected, and if the login by the user A of the portable terminal 2a is not made even if the continuous operation waiting time is exceeded, the MFP 1 The display on the display unit 134 is switched to the general login screen D1 shown in FIG.

  As described above, when the distance from the mobile terminal 2 when the wireless communication with the mobile terminal 2 is disconnected is not large or small (when the distance is more than the minimum distance and less than the limit distance), only the user A of the mobile terminal 2 Since the restricted login screen D7 that can be logged in is displayed on the display unit 134 of the MFP 1, the operability of the user A of the mobile terminal 2 is ensured while preventing the situation where a third party can use the MFP 1 as it is to ensure security. can do.

  FIG. 16 is a diagram for explaining an operation when wireless communication with the mobile terminal 2a is disconnected in a state where the distance between the MFP 1 and the mobile terminal 2a exceeds the limit distance L1.

If the reconnection is not performed, the MFP 1 cancels the login state of the user A and resets the settings, and then transfers the right to use the MFP 1 to another portable terminal 2b waiting for the turn. The display on the display unit 134 of the MFP 1 is switched to the remote connection screen D5.

  As a result, the general login screen D1 is displayed on the display unit 220 of the portable terminal 2b to which the usage right has been transferred, and when the user B logs in, an operation screen (for example, the screen D4) of the MFP 1 is displayed according to the operation of the user B. Is displayed. Thereafter, the same operation as that performed on the mobile terminal 2a is performed on the mobile terminal 2b.

  When the user A performs an operation from the operation panel of the MFP 1 on which the operation screen D3 is displayed within the connection operation waiting time after the wireless communication between the portable terminal 2a and the MFP 1 is disconnected, as shown in FIG. The continuous use from the MFP 1 becomes possible. In this case, the order waiting screen D6 is continuously displayed on the display unit 220 of the portable terminal 2b.

  Further, when the user A reconnects to the MFP 1 from the portable terminal 2a within the connection operation waiting time after disconnection of the wireless communication between the portable terminal 2a and the MFP 1, as shown in FIG. On the display unit 220, the screen D3 displayed on the portable terminal 2a when disconnected is displayed again, and the display on the display unit 134 of the MFP 1 is switched to the remote connection in-progress screen D5. Further, the order waiting screen D6 is continuously displayed on the display unit 220 of the portable terminal 2b.

  FIG. 20 shows another portable terminal 2b waiting for the turn when the wireless communication with the portable terminal 2a is disconnected in a state where the distance between the MFP 1 and the portable terminal 2a is not more than the limit distance L1 and exceeds the minimum distance L2. It is a figure for demonstrating operation | movement when there exists.

  The process until the wireless communication between the MFP 1 and the portable terminal 2a is disconnected is the same as in the case of FIG. When the wireless connection with the mobile terminal 2a is disconnected, a restricted login screen D7 that allows only the user A to log in is displayed on the display unit 134 of the MFP 1 while maintaining the login state of the user A of the mobile terminal 2a. The display screen 220 displays a connection screen D2.

  Further, the MFP 1 sets a continuous operation waiting time proportional to the distance from the mobile terminal 2a when the wireless communication is disconnected, and if the login by the user A of the mobile terminal 2a is not made even if the continuous operation waiting time is exceeded, the MFP 1 Then, after canceling the login state of the user A and resetting the setting, the right to use the MFP 1 is transferred to another portable terminal 2b waiting for the turn. Further, the display on the display unit 134 of the MFP 1 is switched to the remote connection screen D5.

  As a result, the general login screen D1 is displayed on the display unit 220 of the portable terminal 2b to which the usage right has been transferred, and when the user B logs in, an operation screen (for example, the screen D4) of the MFP 1 is displayed according to the operation of the user B.

In this case, the order waiting screen D6 is continuously displayed on the display unit 220 of the portable terminal 2b.

  Further, when the user A reconnects to the MFP 1 from the portable terminal 2a within the connection operation waiting time after disconnection of the wireless communication between the portable terminal 2a and the MFP 1, as shown in FIG. On the display unit 220, the screen D3 displayed on the portable terminal 2a when disconnected is displayed again, and the display on the display unit 134 of the MFP 1 is switched to the remote connection in-progress screen D5.

  In FIG. 23, when the wireless communication with the mobile terminal 2a is disconnected in a state where the distance between the MFP 1 and the mobile terminal 2a exceeds the limit distance L1, there is another mobile terminal 2b waiting for the turn. It is a figure for demonstrating the operation | movement at the time.

  The process until the wireless communication between the MFP 1 and the portable terminal 2a is disconnected is the same as in the case of FIG. When the wireless connection with the portable terminal 2a is disconnected, the remote connection in-progress screen D5 is continuously displayed on the display unit 134 of the MFP 1, and the connection screen D2 is displayed on the display unit 220 of the portable terminal 2a.

  If the mobile terminal 2a is moving when the wireless communication is disconnected, an effective return time is set. If the user A of the mobile terminal 2a does not reconnect to the MFP 1 from the mobile terminal 2a even if the effective return time is exceeded, The MFP 1 cancels the login state of the user A and resets the settings, and then transfers the right to use the MFP 1 to another portable terminal 2b waiting for the turn. The effective return time is set when the user A of the mobile terminal 2a is moving even if it exceeds the limit distance L1, and the user A of the mobile terminal 2a is aware that the user A has gone out of the wireless communication range. This is because the user A is permitted to continue using the MFP 1 because it is considered that the user is moving to return to the effective communication range. If the mobile terminal 2a has not moved when the wireless communication is disconnected, the MFP 1 immediately transfers the usage right to another mobile terminal 2b without setting the valid return time.

  As a result, the general login screen D1 is displayed on the display unit 220 of the portable terminal 2b to which the usage right has been transferred. After the user B logs in, the operation screen of the MFP 1 (for example, the screen D4, for example) is displayed. ) Is displayed. Thereafter, the same operation as that performed on the mobile terminal 2a is performed on the mobile terminal 2b.

  When the user A reconnects to the MFP 1 from the portable terminal 2a within the connection operation waiting time after disconnection of the wireless communication between the portable terminal 2a and the MFP 1, as shown in FIG. 24, the display unit 220 of the portable terminal 2a The operation screen D3 displayed on the portable terminal 2a when the communication is disconnected is displayed, and the MFP 1 can be continuously used. In this case, the order waiting screen D6 is continuously displayed on the display unit 220 of the portable terminal 2b. Further, the remote connection screen D5 is continuously displayed on the display unit 134 of the MFP 1.

  Also, in the embodiment of FIGS. 17 to 24, when there is another mobile terminal 2c waiting for turn in addition to the mobile terminal 2b waiting for turn, the wireless communication between the mobile terminal 2b and the MFP 1 is disconnected. The operation is the same as the operation when the wireless communication between the portable terminal 2a and the MFP 1 is disconnected.

  FIG. 25 is a flowchart showing the operation of the MFP 1 when disconnected from the portable terminal 2a. This operation is executed by the CPU 101 of the MFP 1 operating according to an operation program recorded on a recording medium such as the ROM 102.

  When the wireless communication with the mobile terminal 2a is disconnected, the distance to the mobile terminal 2a is measured in step S31, and the waiting time counter is reset to zero in step S32.

  In step S33, it is checked whether the distance to the portable terminal 2a is within the limit distance L1, and if it is within the limit distance L1 (YES in step S33), it is checked in step S34 whether it is within the minimum distance L2. If within the minimum distance L2 (YES in step S34), in step S341, the operation screen displayed on the display unit 220 of the mobile terminal 2a at the time of disconnection is displayed on the display unit 134, and then the process proceeds to step S35. If it is not within the minimum distance L2 (NO in step S34), after the restricted login screen D7 is displayed on the display unit 134 in step S36, the process proceeds to step S35.

  In step S35, after setting a time proportional to the distance as the continuous operation waiting time, the process proceeds to step S41.

  If it is not within the limit distance L2 in step S33 (NO in step S33), it is determined in step S37 whether there is a user waiting for turn (other portable terminal 2b waiting for turn). If it does not exist (NO in step S37), the general login screen D1 is displayed on the display unit 134 in step S38, and then the process proceeds to step S41. If there is a waiting user (YES in step S37), it is determined in step S39 whether or not the mobile terminal 2a has moved. If not moving (NO in step S39), the process proceeds to step S41. If it has moved (YES in step S39), after setting the effective return time to the continuous waiting time in step S40, the process proceeds to step S41.

  In step S41, it is determined whether the user A of the first portable terminal 2a has performed a continuous operation (including a login operation). If the operation is continued (YES in step S41), in step S49, the restricted login screen D7 or the general login screen D1 displayed on the display unit 134 is canceled and the operation screen at the time of disconnection is displayed. finish.
