FIG. 9 is a diagram illustrating an example of the display surface 4AS and the touch surface 4BS. FIG. 10 is a diagram illustrating an example of the composition screen 7C.

  In the MFP unit 2, the configuration data storage unit 201 includes screen configuration data 6 A 1 indicating the arrangement of each icon configuring the MFP screen 7 A for each MFP screen 7 A that is a screen for the user to operate the MFP unit 2. Stored in advance.

  For example, a plurality of icons are arranged on the MFP screen 7A as shown in FIG. The screen configuration data 6A1 of the MFP screen 7A shows the attributes of each of these icons and includes image data of each of these icons.

  For example, a plurality of icons 8A are arranged on the desktop screen 7A1, which is one of the MFP screens 7A, as shown in FIG. The screen configuration data 6A1 of the desktop screen 7A1 indicates the attributes of each of these icons 8A and includes image data of each of these icons. The clock icon 8A1 indicates the time.

  In the present embodiment, the size (length and length) of each MFP screen 7A is determined in advance and is the same size as the display surface 4AS (see FIG. 9) of the display module 4A. The same applies to a server screen 7B described later. For the sake of simplicity of explanation, a case will be described as an example where the resolution of the display surface 4AS and the resolution of the touch surface 4BS (see FIG. 9) of the touch panel module 4B are the same. Further, in the display surface 4AS, the touch surface 4BS, and any screen described later, the top left vertex is the origin, the vertical axis is the Y axis, and the horizontal direction is the X axis.

  The screen generation unit 202 generates screen data 6A2 of a display target portion of the MFP screen 7A at predetermined time intervals based on the screen configuration data 6A1 of the MFP screen 7A. Hereinafter, this predetermined time is referred to as “first time T1”. In the present embodiment, the first time T1 is 20 ms (milliseconds). The “display target portion” is a portion to be displayed on the display module 4A in a certain screen.

  At the beginning of the first client program 20P, the left half of the MFP screen 7A (see FIG. 7) divided into left and right is the display target portion. Accordingly, after the first client program 20P is activated, the screen data 6A2 of the display target portion is first generated by the screen generation unit 202.

  The screen data transmission unit 203 transmits the screen data 6A2 to the panel microcomputer 5 every time the screen data 6A2 is generated by the screen generation unit 202. That is, the screen data 6A2 is transmitted to the panel microcomputer 5 every first time T1.

  In the server unit 3, the configuration data storage unit 301 includes screen configuration data 6 B 1 indicating the arrangement of each icon constituting the server screen 7 B for each server screen 7 B that is a screen for the user to operate the server unit 3. Stored in advance.

  For example, a plurality of icons are arranged on the server screen 7B as shown in FIG. The screen configuration data 6B1 of the server screen 7B indicates the attributes of each of these icons, and includes image data of each of these icons.

  For example, a plurality of icons 8B are arranged on the desktop screen 7B1, which is one of the server screens 7B, as shown in FIG. The screen configuration data 6B1 of the desktop screen 7B1 indicates the attributes of these icons 8B and includes image data of each of these icons. The indicator icon 8B1 indicates the current operating state of the CPU 30a.

  The screen generation unit 302 generates screen data 6B2 of the display target portion of the server screen 7B at predetermined time intervals based on the screen configuration data 6B1 of the server screen 7B. Hereinafter, this predetermined time is referred to as “second time T2”. In the present embodiment, the second time T2 is 10 ms.

  At the beginning of the second client program 30P, the left half of the server screen 7B divided into two equal parts to the left and right is the display target part, and screen data 6B2 of this display target part is generated.

  The screen data transmission unit 303 transmits the screen data 6B2 to the panel microcomputer 5 every time the screen data 6B2 is generated by the screen generation unit 302. That is, the screen data 6B2 is transmitted to the panel microcomputer 5 every second time T2.

  By the way, the display surface 4AS of the display module 4A and the touch surface 4BS of the touch panel module 4B are divided into two left and right regions by a boundary 40D as shown in FIG. The left area 40L, which is the left area, is used for displaying or operating the MFP screen 7A in principle. The right area 40R, which is the right area, is used for displaying and operating the server screen 7B in principle.

  Based on the latest screen data 6A2 of the screen data 6A2 received from the MFP unit 2 and the latest screen data 6B2 of the screen data 6B2 received from the server unit 3, the screen composition unit 501 At a shorter one of T1 and second time T2 (second time T2 in this embodiment), the display target portion of MFP screen 7A and the display target portion of server screen 7B are combined side by side. Thereby, the screen data 6C2 of the composite screen 7C is generated. The composite screen 7C is a screen in which the MFP screen 7A and the server screen 7B are arranged side by side as shown in FIG.

  The screen output unit 502 causes the video board 50g to execute a process of converting the screen data 6C2 into the video signal 6C3 and outputting it to the display module 4A every time the screen data 6C2 is generated by the screen composition unit 501.

  Then, the display module 4A displays a composite screen 7C based on the video signal 6C3.

  Through the above processing, the display target portion of the MFP screen 7A is displayed in the left region 40L at a frame rate of 1 / T1, and the display target portion of the server screen 7B is displayed in the right region 40R at a frame rate of 1 / T2. Is displayed. However, while the operation of changing the boundary 40D (see FIG. 9) between the left region 40L and the right region 40R is being performed, the lower frame rate is unified and displayed. This will be described later.

  FIG. 11 is a diagram illustrating an example of a change in the composite screen 7C. FIG. 12 is a diagram illustrating an example of a change in the composite screen 7C.

  A user can operate either the MFP unit 2 or the server unit 3 by touching the touch surface 4BS and performing tap, flick, drag, or the like.

  The touch panel module 4B transmits coordinate data 6E indicating the coordinates of the touched position to the panel microcomputer 5 periodically, for example, every 10 ms while the touch surface 4BS is being touched.

  In the panel microcomputer 5, the screen-related data storage unit 503 stores boundary coordinate data 6D. The boundary coordinate data 6D indicates coordinates on the display surface 4AS and the touch surface 4BS of the boundary 40D. At the beginning of the relay program 50P, a line segment that equally divides the display surface 4AS and the touch surface 4BS into left and right is set as a boundary 40D. That is, the coordinates of this line segment are shown in the boundary coordinate data 6D as the coordinates of the boundary 40D.

  The screen-related data storage unit 503 stores a first time T1 and a second time T2 in advance.

  When the coordinate data 6E starts to be received by the panel microcomputer 5, the object determination unit 504 determines whether the operation by the user is an operation on the MFP unit 2, the operation on the server unit 3, or an operation for changing the boundary 40D. Determine as follows.

  The object determination unit 504 determines whether or not the boundary 40D is touched based on the coordinates indicated in the coordinate data 6E received first after the touch is started and the coordinates of the boundary 40D indicated in the boundary coordinate data 6D. Determine. When it is determined that the touch has been made, it is determined that the operation by the user is an operation for changing the boundary 40D.

  Otherwise, the object determination unit 504 determines that the operation by the user is an operation on the MFP unit 2 if the coordinates indicated by the coordinate data 6E are any coordinates in the left region 40L. If the coordinates shown in the coordinate data 6E are any coordinates in the right region 40R, it is determined that the operation by the user is an operation on the server unit 3.

  When the object determination unit 504 determines that the user's operation is an operation on the MFP unit 2, the first coordinate data transmission unit 505 receives the first received coordinate data 6E and continuously thereafter. The coordinate data 6E is transmitted to the MFP unit 2 one after another.

  When the object determination unit 504 determines that the user's operation is an operation on the server unit 3, the second coordinate data transmission unit 506 receives the first received coordinate data 6E and continuously received thereafter. The coordinate data 6E is transmitted to the server unit 3 one after another.

  By the way, the coordinate indicated in the coordinate data 6E received first is any one of the coordinates in the left region 40L, and the coordinates indicated in the coordinate data 6E continuously received thereafter exceed the coordinates of the boundary 40D and are moved to the right. When the object determining unit 504 determines that any coordinate in the area 40R is reached, the second coordinate data transmitting unit 506 transmits the coordinate data 6E after exceeding the coordinates of the boundary 40D to the server unit 3. At this time, the first coordinate data transmission unit 505 stops transmitting the coordinate data 6E after exceeding the coordinates of the boundary 40D.

  Alternatively, the coordinate indicated in the coordinate data 6E received first is any one of the coordinates in the right region 40R, and the coordinates indicated in the coordinate data 6E continuously received thereafter exceed the coordinates of the boundary 40D and are left. When the object determining unit 504 determines that any coordinate in the area 40L has been reached, the first coordinate data transmitting unit 505 transmits the coordinate data 6E after exceeding the coordinates of the boundary 40D to the MFP unit 2. At this time, the second coordinate data transmission unit 506 stops transmitting the coordinate data 6E after exceeding the coordinates of the boundary 40D.

  If the origin of the touch surface 4BS and the origin of the MFP screen 7A do not match, the MFP unit 2 corrects the coordinate data 6E based on the boundary coordinate data 6D. Similarly, when the origin of the touch surface 4BS and the origin of the server screen 7B do not match, the server unit 3 corrects the coordinate data 6E based on the boundary coordinate data 6D.

  In the MFP unit 2, the next process determining unit 204 determines a process to be executed next (hereinafter referred to as “next process”) based on the coordinates indicated in the coordinate data 6 E received from the panel microcomputer 5. . Then, the next process determined by the next process determination unit 204 is executed in the MFP unit 2.

  In the server unit 3, the next process determination unit 304 determines the next process based on the coordinates indicated in the coordinate data 6 </ b> E received from the panel microcomputer 5. Then, the determined next process is executed in the server unit 3.

  In the panel microcomputer 5, when the object determining unit 504 determines that the user's operation is an operation for changing the boundary 40D, the boundary changing unit 507 performs the process for changing the boundary 40D as follows. Do.

  The boundary changing unit 507 updates the boundary coordinate data 6D so that the X coordinate of the coordinate indicated by the latest coordinate data 6E among the coordinate data 6E received continuously becomes the X coordinate of the boundary 40D. Thereby, the boundary 40D is changed. In addition, the left region 40L and the right region 40R are also changed.

  Based on the updated boundary coordinate data 6D, the boundary changing unit 507 changes the changed time every longer time of the first time T1 and the second time T2, that is, every first time T1. Boundary change data 6F1 indicating the width of the left area 40L is generated and transmitted to the MFP unit 2. In addition, based on the updated boundary coordinate data 6D, the boundary change data 6F2 indicating the width of the changed right region 40R is generated for each longer time, that is, for each first time T1, and the server is generated. Send to unit 3.

  Here, the boundary changing unit 507 transmits the first boundary change data 6F1 to the MFP unit 2 and simultaneously transmits the first boundary change data 6F2 to the server unit 3. That is, the boundary change data 6F1 and the boundary change data 6F2 are transmitted in synchronization.

  Every time the boundary change data 6F1 is received in the MFP unit 2 (that is, every first time T1), the screen generation unit 202 uses a part of the MFP screen 7A as a display target portion as the boundary change data 6F1. Widen or narrow to fit the width shown in. That is, the portion to be displayed is expanded or narrowed every first time T1. Either the left or right side of the display target part may be widened or narrowed. Then, every time the width is increased or decreased (that is, every first time T1), screen data 6A2 of a new display target portion is generated. The screen data transmission unit 203 transmits the screen data 6A2 to the panel microcomputer 5 every time the screen data 6A2 is generated (that is, every first time T1).

  In the server unit 3, each time the boundary change data 6F2 is received, the screen generation unit 302 widens or narrows the display target portion of the server screen 7B in accordance with the width indicated by the boundary change data 6F2. That is, the display target portion is expanded or narrowed not every second time T2, but every first time T1. The method for expanding and narrowing the display target portion of the server screen 7B is the same as the method for expanding and narrowing the display target portion of the MFP screen 7A. Then, every time the width is increased or decreased (that is, every first time T1), screen data 6B2 of a new display target portion is generated.

  The screen data transmission unit 303 transmits the screen data 6B2 to the panel microcomputer 5 every time the screen data 6B2 is generated (that is, every first time T1).

  In the panel microcomputer 5, the screen composition unit 501 generates the screen data 6C2 of the composite screen 7C based on the screen data 6A2 and the screen data 6B2 basically as described above.

  However, the screen composition unit 501 generates the screen data 6C2 based on the latest screen data 6A2 and the screen data 6B2 received in the same order as the order in which the screen data 6A2 was received. Alternatively, the screen data 6C2 is generated based on the latest screen data 6B2 and the screen data 6A2 received in the same order as the order in which the screen data 6B2 was received. That is, it generates based on the Nth received screen data 6A2 and the Nth received screen data 6B2. It is not necessarily generated based on the latest screen data 6A2 and the latest screen data 6B2. In this way, screen data 6C2 is generated in synchronization.

  The screen output unit 502 causes the video board 50g to execute a process of converting the screen data 6C2 into the video signal 6C3 and outputting it to the display module 4A every time the screen data 6C2 is generated by the screen composition unit 501. The display module 4A displays a composite screen 7C based on the video signal 6C3.

  Since the synchronization is performed as described above, for example, when the boundary 40D moves to the right, as shown in FIG. 11, the MFP screen 7A becomes wide with no gap between the MFP screen 7A and the server screen 7B. And the server screen 7B becomes narrow.

  If synchronization is not performed as described above, the following processing is performed. As a result, a new composite screen 7C is unnaturally displayed.

  That is, the boundary changing unit 507 updates the boundary coordinate data 6D every time the coordinate data 6E is received (that is, every 10 ms). Each time the boundary coordinate data 6D is updated (that is, every 10 ms), the boundary change data 6F1 and the boundary change data 6F2 are generated based on the boundary coordinate data 6D, and are sent to the MFP unit 2 and the server unit 3, respectively. Send every 10ms.

  The screen generation unit 202 of the MFP unit 2 normally generates the screen data 6A2 every first time T1 (that is, every 20 ms). Therefore, the screen data 6A2 is generated based on the boundary change data 6F1 received every 20 ms. Note that the boundary change data 6F1 that is not used to generate the screen data 6A2 is discarded.

  The screen data transmission unit 203 transmits the screen data 6A2 every time the screen data 6A2 is generated (that is, every 20 ms).

  The screen generation unit 302 of the server unit 3 generates the screen data 6B2 as usual, that is, every second time T2 (that is, every 10 ms). The screen data transmission unit 303 transmits the screen data 6B2 every time the screen data 6B2 is generated.

  The screen composition unit 501 of the panel microcomputer 5 performs screen data 6C2 of the composite screen 7C based on the latest screen data 6A2 and the latest screen data 6B2 as usual, that is, every second time T2 (that is, every 10 ms). Is generated. The screen output unit 502 displays a new composite screen 7C on the display module 4A.

  Therefore, for example, when the boundary 40D moves to the right, when the screen data 6A2 is not generated (that is, at each time of 10 ms, 30 ms, 50 ms, 70 ms, etc.), as shown in FIG. 12, the MFP screen 7A and the server screen 7B A composite screen 7C in which a gap is generated may be displayed.

  While the operation of changing the boundary 40D is performed by the above processing, the lower frame rate (in this embodiment, 1 / T1) is unified and the display target portion of the MFP screen 7A and the server screen 7B The display target portion is displayed as a composite screen 7C.

  FIG. 13 is a diagram showing an example of the overall processing flow of the MFP unit 2 and the server unit 3. FIG. 14 is a diagram showing an example of the overall processing flow of the panel microcomputer 5.

  Next, an example of the overall processing flow of each of the MFP unit 2, the server unit 3, and the panel microcomputer 5 will be described with reference to flowcharts.

  After starting the operating system, the MFP unit 2 executes processing according to the procedure shown in FIG. 13 based on the first client program 20P. The server unit 3 also executes processing in the procedure shown in FIG. 13 based on the second client program 30P after the operating system is started.

  The panel microcomputer 5 executes processing in the procedure shown in FIG. 14 based on the relay program 50P after the operating system is started.

  The MFP unit 2 generates screen data 6A2 of the display target portion of the MFP screen 7A (see FIG. 7) at every first time T1, and transmits it to the panel microcomputer 5 (# 901 in FIG. 13).

  The server unit 3 generates screen data 6B2 of the display target portion of the server screen 7B (see FIG. 8) every second time T2 and transmits it to the panel microcomputer 5 (# 901).

  When panel microcomputer 5 receives screen data 6A2 and screen data 6B2 from MFP unit 2 and server unit 3, respectively (Yes in # 951 in FIG. 14), if the user is currently operating boundary 40D (in # 952). Yes), based on the latest screen data 6A2 of the screen data 6A2 received every first time T1 and the screen data 6B2 received in the same order as the screen data 6A2 was received (or MFP screen 7A based on the latest screen data 6B2 of screen data 6B2 received every first time T1 and screen data 6A2 received in the same order as the screen data 6B2 was received) By combining the display target portions of the server screen 7B side by side and combining them, the composition screen 7C (see FIG. 10). ) To generate the screen data 6C2 of (# 953). That is, the screen data 6C2 is generated in synchronization. The operation target is determined in step # 957 described later.

  On the other hand, if the user is not currently operating the boundary 40D (No in # 952), the latest screen data 6A2 of the screen data 6A2 received every first time T1 and every second time T2 are received. By combining the display target portions of the MFP screen 7A and the server screen 7B side by side based on the latest screen data 6B2 of the screen data 6B2, the screen data 6C2 of the composite screen 7C (see FIG. 10) is combined. Generate (# 954). That is, the screen data 6C2 is generated without synchronization.

  The panel microcomputer 5 outputs the generated video signal 6C3 of the screen data 6C2 to the display module 4A (# 955).

  When the panel microcomputer 5 receives the coordinate data 6E from the touch panel module 4B (Yes in # 956), the panel microcomputer 5 determines which of the MFP screen 7A, the server screen 7B, and the boundary 40D is being operated (# 957). ). That is, the user's operation target is determined.

  When it is determined that the operation target is the boundary 40D (that is, the boundary 40D is operated) (Yes in # 958), the panel microcomputer 5 updates the boundary coordinate data 6D (# 959). At this time, the boundary coordinate data 6D is updated at the first time T1.

  The panel microcomputer 5 generates the boundary change data 6F1 and the boundary change data 6F2 at the first time T1 based on the updated boundary coordinate data 6D, and transmits them to the MFP unit 2 and the server unit 3, respectively. (# 960). At this time, the first boundary change data 6F1 and the first boundary change data 6F2 are transmitted simultaneously. That is, it transmits in synchronization.

  When the panel microcomputer 5 determines that the operation target is the MFP unit 2 (No in # 958, Yes in # 961), the panel microcomputer 5 transmits the coordinate data 6E to the MFP unit 2 (# 962). When it is determined that the operation target is the server unit 3 (No in # 958, No in # 961), the coordinate data 6E is transmitted to the server unit 3 (# 963).

  The panel microcomputer 5 executes the processes of steps # 951 to # 963 as appropriate until the relay program 50P is finished (No in # 964).

  When the MFP unit 2 receives the coordinate data 6E from the panel microcomputer 5 (Yes in # 902 in FIG. 13), the MFP unit 2 determines and executes the next process (# 903).

  While receiving the boundary change data 6F1 (Yes in # 904), the MFP unit 2 receives the boundary change data 6F1 (that is, every first time T1) instead of performing the process of step # 901. (Ii), the screen data 6A2 of the display target portion whose width is widened or narrowed based on the boundary change data 6F1 is generated and transmitted to the panel microcomputer 5 (# 905).

  When the server unit 3 receives the coordinate data 6E from the panel microcomputer 5 (Yes in # 902), the server unit 3 determines and executes the next process (# 903). While the boundary change data 6F2 is received (Yes in # 904), instead of performing the process of step # 901, the boundary change is performed every time the boundary change data 6F2 is received (that is, every first time T1). Based on the data 6F2, the screen data 6B2 of the display target part whose width has been widened or narrowed is generated and transmitted to the panel microcomputer 5 (# 905). If the boundary change data 6F2 is not received, the screen data 6B2 is generated and transmitted to the panel microcomputer 5 every second time T2 (# 901).

  Each of the MFP unit 2 and the server unit 3 appropriately executes the processes of steps # 901 to # 905 until the first client program 20P and the second client program 30P are finished (No in # 906).

  According to the present embodiment, when the sizes of the screens of the two systems displayed on one display change, it is possible to prevent the screen from being displayed unnaturally during the change compared to the conventional case.

  FIG. 15 is a diagram illustrating an example of a change in the composite screen 7C. FIG. 16 is a diagram illustrating an example of a change in the display target portion of the MFP screen 7A. FIG. 17 is a diagram illustrating an example of a change in the display target portion of the server screen 7B. FIG. 18 is a diagram illustrating an example of a change in the composite screen 7C. FIG. 19 is a diagram illustrating an example of the overlap between the display target portion of the MFP screen 7A and the display target portion of the server screen 7B. FIG. 20 is a diagram illustrating an example of the overlap between the display target portion of the MFP screen 7A and the display target portion of the server screen 7B.

  In the present embodiment, each of the MFP unit 2 and the server unit 3 transmits the screen data 6A2 and the screen data 6B2 to the panel microcomputer 5. However, the MFP unit 2 may convert the screen data 6A2 into a video signal and transmit the video signal to the panel microcomputer 5. Alternatively, the server unit 3 may convert the screen data 6B2 into a video signal and transmit the video signal to the panel microcomputer 5. The panel microcomputer 5 may combine the video signals received from the MFP unit 2 and the server unit 3 respectively.

  In the present embodiment, synchronization is achieved when the width of the display target portion of the MFP screen 7A and the width of the display target portion of the server screen 7B are changed. However, not only in this case, but also when displaying a state in which the icon moves from one screen to the other screen across the boundary 40D as shown in FIG. The process when the icon moves will be described by taking as an example a case where the composite screen 7C is a composite of the display target portion of the desktop screen 7A1 and the desktop screen 7B1.

  The user gives an instruction to move the file of the icon 8A2 arranged in the display target portion of the desktop screen 7A1 to the desktop of the server unit 3.

  Then, the next process determining unit 204 of the MFP unit 2 determines the process for moving the file of the icon 8A2 as the next process. Then, the next process is executed as follows.

  The screen generation unit 202 combines the icon 8A2 from the current position to the specific position of the display target portion of the desktop screen 7B1 at a predetermined speed from now on, and the composite screen 7C for each first time T1. The position of the icon 8A2 in is calculated. Each time the position of the icon 8A2 is calculated, the position is notified to the server unit 3. At this time, the image data of the icon 8A2 is transmitted to the server unit 3.

  Further, the screen generation unit 202 generates screen data 6A2 of the display target portion of the desktop screen 7A1 in which the icon 8A2 is arranged at the calculated position as shown in FIG. 16 at each first time T1. The screen data transmission unit 203 transmits the screen data 6A2 to the panel microcomputer 5.

  In the server unit 3, the screen generation unit 302 is calculated as shown in FIG. 17 every time the position of the icon 8A2 is notified (that is, every first time T1, not every second time T2). Screen data 6B2 of the display target portion of the desktop screen 7B1 in which the icon 8A2 is arranged at the position is generated. The screen data transmission unit 303 transmits the screen data 6B2 to the panel microcomputer 5.

  In the panel microcomputer 5, the screen composition unit 501 is based on the latest screen data 6A2 and the screen data 6B2 received in the same order as the screen data 6A2 was received (or similar to this embodiment) (or Based on the latest screen data 6B2 and the screen data 6A2 received in the same order as the screen data 6B2 was received, the screen data 6C2 of the composite screen 7C is generated. The composite screen 7C is displayed by the screen output unit 502 and the display module 4A.

  Thereby, for example, a state in which the icon 8A2 moves from the MFP screen 7A to the server screen 7B beyond the boundary 40D as shown in FIG. 15 is displayed on the touch panel display 4.

  Thereafter, the file corresponding to the icon 8A2 is transmitted to the server unit 3 and stored on the desktop of the server unit 3. This file is deleted from the desktop of the MFP unit 2.

  Further, the MFP unit 2 performs a process of updating the screen configuration data 6A1 of the desktop screen 7A1 so that the icon 8A2 is deleted from the desktop screen 7A1. Further, the server unit 3 performs a process of updating the screen configuration data 6B1 of the desktop screen 7B1 so that the icon 8A2 is added to the screen configuration data 6B1.

  In the present embodiment, the boundary change unit 507 generates the boundary change data 6F1 and the boundary change data 6F2 for each first time T1 based on the updated boundary coordinate data 6D to generate the MFP unit 2 and the server unit. Sent to each of the three. However, the boundary change data 6F1 and the boundary change data 6F2 may be generated and transmitted every second time T2 (that is, every shorter time). In this case, the following processing may be performed.

  When the panel microcomputer 5 receives the coordinate data 6E transmitted from the touch panel module 4B every 10 ms, the boundary changing unit 507 updates the boundary coordinate data 6D. Then, based on the updated boundary coordinate data 6D, each of the boundary change data 6F1 and the boundary change data 6F2 is generated and transmitted to each of the MFP unit 2 and the server unit 3 at each second time T2. As in the present embodiment, synchronization is established when the first boundary change data 6F1 and the first boundary change data 6F2 are transmitted.

  When the boundary change data 6F1 is received in the MFP unit 2, the screen generation unit 202 generates screen data 6A2.

  By the way, as described in the present embodiment, the screen generation unit 202 generates the screen data 6A2 not every second time T2 but every first time T1 (that is, every 20 ms instead of every 10 ms). Therefore, of the boundary change data 6F1 received every second time T2, the boundary received every other time of the second time T2 (that is, at each time of 20 sm, 40 ms, 60 ms...). Based on the change data 6F1, screen data 6A2 is generated every first time T1. Note that the boundary change data 6F1 that is not used to generate the screen data 6A2 is discarded.

  The screen data transmission unit 203 transmits the screen data 6A2 to the panel microcomputer 5 every time the screen data 6A2 is generated (that is, every first time T1).

  In the server unit 3, every time the boundary change data 6F2 is received (that is, every second time T2), the screen generation unit 302 generates screen data 6B2 based on the boundary change data 6F2. The screen data transmission unit 303 transmits the screen data 6B2 to the panel microcomputer 5 every time the screen data 6B2 is generated (that is, every second time T2).

  When the panel microcomputer 5 receives the screen data 6A2 and the screen data 6B2, the screen composition unit 501 is based on the Nth received screen data 6A2 and the (2 × N) th received screen data 6B2. Screen data 6C2. For example, the screen data 6C2 is generated based on the screen data 6A2 that is received in the third order and the screen data 6B2 that is received in the sixth order. Note that the screen data 6B2 that has not been used to generate the screen data 6C2 is discarded.

  Then, the composite screen 7C is displayed by the screen output unit 502 and the display module 4A.

  Alternatively, when the boundary coordinate data 6D is updated every second time T2, each device may perform the following processing.

  When the panel microcomputer 5 receives the coordinate data 6E transmitted from the touch panel module 4B every 10 ms, the boundary changing unit 507 updates the boundary coordinate data 6D. Then, based on the updated boundary coordinate data 6D, each of the boundary change data 6F1 and the boundary change data 6F2 is generated and transmitted to each of the MFP unit 2 and the server unit 3 at each second time T2. As in the present embodiment, synchronization is established when the first boundary change data 6F1 and the first boundary change data 6F2 are transmitted.

  Here, the boundary change unit 507 transmits the first boundary change data 6F2 to the server unit 3 again when the second time T2 has elapsed once since the transmission of the first boundary change data 6F2. At this time, the second boundary change data 6F2 is generated. Next, when the second time T2 has elapsed once, the second boundary change data 6F2 is transmitted to generate the third boundary change data 6F2. That is, after the first boundary change data 6F2 is generated and transmitted, the Nth boundary change data 6F2 is generated and the (N−1) th boundary change data 6F2 is transmitted every second time T2. To do. This process is continued until the coordinate data 6E is not received.

  In MFP unit 2, screen generation unit 202 generates screen data 6A2 every time boundary change data 6F1 is received (that is, every first time T1). The screen data transmission unit 203 transmits the screen data 6A2 to the panel microcomputer 5 every time the screen data 6A2 is generated.

  In the server unit 3, the screen generation unit 302 generates screen data 6B2 every time the boundary change data 6F2 is received (that is, every second time T2). The screen data transmission unit 303 transmits the screen data 6B2 to the panel microcomputer 5 every time the screen data 6B2 is generated.

  When screen data 6A2 and screen data 6B2 are received in panel microcomputer 5, screen composition unit 501 first screen data based on screen data 6A2 received first and screen data 6B2 received first. 6C2 is generated. When the second time T2 has passed once, the second screen data 6C2 is generated based on the screen data 6A2 received first and the screen data 6B2 received second. Next, when the second time T2 has passed once, the third screen data 6C2 is generated based on the screen data 6A2 received second time and the screen data 6B2 received third time.

  That is, the screen composition unit 501 generates the 2M-th screen data 6C2 based on the screen data 6B2 received at the 2Mth time and the screen data 6A2 received at the Mth time. The (2M-1) th screen data 6C2 is generated based on the screen data 6B2 received at the (2M-1) th time and the screen data 6A2 received at the Mth time. This is continued until the operation of the boundary 40D is completed.

  Further, in the 2Mth time, the screen composition unit 501 displays the MFP screen 7A (that is, the screen that is received at the lower frequency) as the display target portion of the server screen 7B (that is, the screen data screen that is received at the higher frequency). The screen data 6C2 is generated so as to be in front of the display target portion of the data screen.

  Then, the composite screen 7C is displayed by the screen output unit 502 and the display module 4A.

  As a result, for example, as shown in FIG. 18, the display target portion of the MFP screen 7A is narrowed so as to be gradually hidden by the display target portion of the server screen 7B, and the display target portion of the server screen 7B is displayed on the MFP screen 7A. A composite screen 7C that is widened so as to gradually hide the display target portion is displayed.

  Alternatively, when the boundary coordinate data 6D is updated every second time T2, each device may perform the following processing.

  In the panel microcomputer 5, when the coordinate data 6E transmitted from the touch panel module 4B is received (every 10 ms), the boundary changing unit 507 updates the boundary coordinate data 6D every second time T2. Each time the boundary coordinate data 6D is updated, boundary change data 6F1 and boundary change data 6F2 are generated based on the boundary coordinate data 6D and transmitted to the MFP unit 2 and the server unit 3, respectively. As in the present embodiment, synchronization is established when the first boundary change data 6F1 and the first boundary change data 6F2 are transmitted.

  In the MFP unit 2, the screen generation unit 202 generates screen data 6A2 based on the boundary change data 6F1 every time the boundary change data 6F1 is received (that is, every second time T2). However, as described above, the screen generation unit 202 cannot generate the screen data 6A2 at a frequency higher than 20 ms. Therefore, by reducing the load on the MFP unit 2, it can be generated at a frequency higher than 20 ms. Specifically, the screen data 6A2 is generated by reducing the resolution of the display target portion of the MFP screen 7A to a lower resolution than normal (for example, a resolution that is half the normal resolution). The screen data transmission unit 203 transmits the screen data 6A2 to the panel microcomputer 5 every time the screen data 6A2 is generated.

  In the server unit 3, the screen generation unit 302 generates screen data 6B2 based on the boundary change data 6F2 every time the boundary change data 6F2 is received. The screen data transmission unit 303 transmits the screen data 6B2 to the panel microcomputer 5 every time the screen data 6B2 is generated.

  In the panel microcomputer 5, the screen composition unit 501 generates screen data 6C2 based on the latest screen data 6A2 and screen data 6B2 received in the same order as the screen data 6A2 was received. Alternatively, the screen data 6C2 is generated based on the latest screen data 6B2 and the screen data 6A2 received in the same order as the order in which the screen data 6B2 was received.

  Then, the composite screen 7C is displayed by the screen output unit 502 and the display module 4A.

  When the boundary coordinate data 6D is updated every first time T1 instead of every second time T2, the screen generation unit 302 of the server unit 3 receives the boundary change data 6F1 (that is, the first time The screen data 6B2 may be generated every time T1). In this case, since there is room in the resources of the server unit 3, the screen data 6B2 is generated by raising the resolution of the display target portion of the server screen 7B to a higher resolution than normal (for example, twice the normal resolution). Also good.

  In the present embodiment, the server unit 3 generates the screen data 6B2 of the display target portion of the server screen 7B and transmits it to the panel microcomputer 5 at every first time T1 regardless of whether or not the boundary 40D is operated. .

  However, while the boundary 40D is operated to move to the right (that is, while the display target portion of the MFP screen 7A is wide), the server unit 3 stops generating and transmitting the screen data 6B2. May be.

  In the panel microcomputer 5, while the screen data 6B2 is not received from the server unit 3 and the screen data 6A2 is received from the MFP unit 2, the screen composition unit 501 receives the screen data 6A2 every time the screen data 6A2 is received. The screen data 6C2 is generated based on the data 6A2 and the latest screen data 6B2 (that is, immediately before the boundary 40D is operated). At this time, as shown in FIG. 19, the screen data 6C2 is generated so that the display target portion of the MFP screen 7A is in front of the display target portion of the server screen 7B.

  Thereafter, when the operation of the boundary 40D ends and the screen data 6B2 starts to be received again from the server unit 3, the screen data 6C2 is generated based on the latest screen data 6B2 and the latest screen data 6A2, as described above.

  Alternatively, while the boundary 40D is operated to move to the left (that is, while the display target portion of the server screen 7B is wide), each device basically performs normal processing. However, as shown in FIG. 20A, the right side of the display target part of the MFP screen 7A and the left side of the display target part of the server screen 7B may overlap. Therefore, when both overlap, the screen composition unit 501 displays the screen data 6C2 so that the display target portion of the server screen 7B is in front of the display target portion of the MFP screen 7A, as shown in FIG. Should be generated.

  In addition, the configuration of the entire MFP 1, the MFP unit 2, and the server unit 3 or each unit, the contents of processing, the order of processing, the data configuration, and the like can be appropriately changed in accordance with the spirit of the present invention.
