     DETAILED DESCRIPTION 
       [0022]    Hereinafter, a description will be given of aspects of the present invention by referring to the drawings. 
       First Aspect 
       [0023]    Here, a description will be given of an aspect of the image processing apparatus including functions to copy, fax, print, scan and input/output a portable medium by referring to the drawings. 
         [0024]    As shown in  FIGS. 1 and 2 , an image processing apparatus  1  is formed approximately in a square shape when viewed from above, and includes an operation panel  9  at the front face side on the upper face thereof. A scanner unit (image reading unit)  3  and an original pressing plate  8  are provided on the upper face of the image processing apparatus  1 . 
         [0025]    The operation panel  9  includes a display  2  and operation keys  4  such as a copy operation key  5 , a facsimile operation key  6 , a scanner operation key  7  and numeric keys  10 . 
         [0026]    The display  2  is arranged approximately at the center of the operation panel  9  in the width direction. The display  2  displays an image data of a medium (original) read by the scanner unit  3  and information when using functions to copy, fax, print and scan. The vertical width of the display  2  is set to be approximately equal to a length obtained by subtracting the vertical width of a read-surface protecting member  3   a  of the scanner unit  3  from the vertical width of a main body of the image processing apparatus  1 . In other words, the display  2  is relatively large. Therefore the display displays individual image data in a large scale. The display  2  is formed in a horizontally-long rectangular shape and able to display a plurality of vertically-long image data (at least three) in parallel. 
         [0027]    For example, as illustrated in  FIG. 4 , the display  2  is formed integrally by connecting in a horizontal direction two unit panels  19   a  and  19   b  having a ratio of the vertical width to the horizontal width of 3 to 4 (or 9 to 16). Further, an integrally formed protective base material  20  is provided on the surface of these two unit panels  19   a  and  19   b . This configuration makes any boundary line between the unit panels  19   a  and  19   b  invisible so that users can clearly view the display  2 . Each of the unit panels  19   a  and  19   b  includes a liquid crystal display (LCD). 
         [0028]    In  FIG. 4 , a description is given by using horizontally-long display  2 . However, as illustrated in  FIG. 5 , a vertically-long display  2  may be used, which is similar in configuration. 
         [0029]    The scanner unit  3  is a known scanner and formed in a size capable of reading, for example, an A4-size original but is not limited to such. The scanner unit  3  is formed in a rectangular shape when viewed from above and arranged so that the longer side is along the horizontal direction of the image processing apparatus. As illustrated in  FIG. 2 , the scanner unit  3  includes the read-surface protecting member  3   a  made of glass, etc., an image sensor  3   b  such as a contact image sensor, a shaft  3   c , a driving belt  3   d  and others. A motor (not illustrated) drives the driving belt  3   d , by which the image sensor  3   b  is moved in a direction of an arrow A shown in  FIG. 2 , and image data of an original placed on the read-surface protecting member  3   a  is read. The read image data is displayed in a color image on the display  2  and printed on a sheet  12  by using the operation keys  4 . 
         [0030]    The sheet  12 , for example, A4-size sheet, is stacked and accommodated in a sheet tray  11 . As illustrated in  FIG. 2 , the sheet tray  11  is provided so as to be taken in and out with respect to the image processing apparatus  1  from the front face thereof. As described above, the sheet  12  is placed in a vertical direction with respect to the main body of the apparatus, and the scanner unit  3  is placed in a horizontal direction. Thus, the image processing apparatus  1  is formed approximately in a square shape as a whole, when viewed from above. 
         [0031]    As illustrated in  FIG. 3B , an image forming unit  13  is disposed below the scanner unit  3 . The sheet tray  11  is disposed further below the image forming unit  13 . When an image is printed on a sheet  12  in response to operation of the operation keys  4 , an uppermost sheet of the sheet  12  placed in the sheet tray  11  is taken out and conveyed while the sheet  12  is U-turned in the longitudinal direction of the sheet  12 , on which the image is printed by a print drum  13   b . Further, a sheet discharge port  13   a  is formed at the front face of the image processing apparatus  1  and the printed sheet  12  is discharged from the sheet discharge port  13   a  to the front face of the apparatus main body. Thereby, the sheet  12  is discharged toward a user who is using the image processing apparatus  1  and the user can easily pick up the sheet  12 . 
         [0032]    Next, a description will be given of a circuit block diagram of the image processing apparatus  1  by referring to  FIG. 6 . The image processing apparatus  1  includes: a Central Processing Unit (CPU)  27 ; a Random Access Memory (RAM)  28 ; a Read Only Memory (ROM)  29  that stores various programs; a bus line  26  that is coupled therewith; an Input/Output (I/O)  25  coupled to the bus line  26 ; a storage device  24  coupled to the bus line  26  (which is, for example, a non-volatile memory such as an Electrically Erasable Programmable Read Only Memory (EEPROM) or a hard disk, or, alternatively, which is a portable medium such as a flush memory); and a communication interface  23  (indicated as I/F in  FIG. 6 ) that is coupled to a communication network  100  to send and receive data with a personal computer  30 . Either a wire communication interface or a wireless communication interface may be used as the communication interface  23 . The I/O  25  is connected with the display  2 , the scanner unit  3 , the operation keys  4  and the image forming unit  13 , as described above, as well as a facsimile transmitting/receiving unit  22 . The facsimile transmitting/receiving unit  22  is connected to a public line. 
         [0033]    The ROM  29  stores programs such as a display control program  29   a  and a control program  29   b . The display control program  29   a  is a program for displaying a plurality of image data for a plurality of pages in parallel on the display  2 . The control program  29   b  is a program for operating the image forming unit  13 , the scanner unit  3  and the facsimile transmitting/receiving unit  22  in response to the operation of the operation keys  4 . 
         [0034]      FIG. 7  shows a relationship of inter-processing communications between a display control processing cp by the display control program  29   a ; a monitor processing mp; an image input processing ip including a copy input processing ip 1 , facsimile receiving processing ip 2 , a print input processing ip 3 , a scanner input processing ip 4  and a portable-medium input processing ip 5 ; an image output processing op including a copy output processing op 1 , a facsimile transmission processing op 2 , a print output processing op 3 , a scanner output processing op 4  and a portable-medium output processing op 5 ; an input content real-time display processing idp; and an output content real-time display processing odp. The display control processing cp and the image input processing ip communicates with each other via the monitor processing mp. The display control processing cp and the image output processing op communicates with each other via the monitor processing mp. The display control processing cp and the input content real-time display processing idp communicate with each other directly. The display control processing cp and the output content real-time display processing odp communicate with each other directly. 
         [0035]      FIG. 8  shows a flowchart of the display control processing cp by the display control program  29   a.    
         [0036]      FIG. 9  shows a flowchart of the output content real-time display processing odp for the facsimile transmission processing op 2 . The output content real-time display processing odp for the facsimile transmission processing op 2  performs display update in response to receiving a notification of progress from the facsimile transmission processing op 2  or monitoring a counter of the facsimile transmission processing op 2 . 
         [0037]    The input content real-time display processing idp for the scanner input processing ip 4  includes substantially only displaying data which is saved in a RAM  28  by the scanner input processing ip 4  as it is on the display  2 . Therefore, a flowchart regarding the processing is not illustrated here. 
         [0038]      FIG. 10  shows a generalized flowchart of the output content real-time display processing odp for various output processing. In general, the output content real-time display processing odp performs display update in response to receiving a notification of progress from the image output processing op or monitoring a counter of the image output processing op. Output content real-time display processing odp differs for every image output processing op, with the above point kept unchanged. 
         [0039]    In general, the input content real-time display processing idp includes substantially only displaying data which is saved in the RAM  28  by the image input processing ip as it is on the display  2 . Therefore, a flowchart regarding the process is not illustrated here. 
         [0040]      FIG. 11  illustrates the first half of a transition example of an input/output real-time display on the display  2  of the image processing apparatus  1  according to the first aspect. In the transition example, three display areas, specifically, an input content display area at which the content of a page to be transmitted by facsimile is displayed, an outputting content display area at which the content of a page now being transmitted by facsimile is displayed and an output content display area at which the content of a page already transmitted by facsimile is displayed are arranged in this order in the display  2  from the right side. 
         [0041]      FIG. 12  illustrates the last half of the transition example of a display on the display  2  of the image processing apparatus  1  according to the first aspect. 
         [0042]    Next, a description will be given of operations of the thus configured image processing apparatus  1  according to the first aspect by referring to  FIG. 1  to  FIG. 12 . 
         [0043]    Hereinafter, a description will be given by exemplifying an operation of the facsimile transmission function, specifically, in a case where the image input processing ip is scanner input processing ip 4  and the image output processing op is facsimile transmission processing opt. 
         [0044]    When the operation keys  4  are operated to instruct facsimile transmission, the display control processing cp changes the screen of the display  2  from stand-by display to input/output processing display (S 101  in  FIG. 8 ). 
         [0045]    Next, the display control processing cp determines whether image input is started (S 102  in  FIG. 8 ). In this instance, the display control processing cp determines to be YES when scanner input processing ip 4  (original reading) is started at the scanner unit  3 . In other words, upon receipt of a notification of starting the image input from the scanner input processing ip 4 , the display control processing cp determines that the scanner input processing ip 4  has been started. Further, monitor processing mp monitors whether the scanner input processing ip 4  is activated. Therefore, when information is obtained from the monitor processing mp that the scanner input processing ip 4  has been activated or an activation flag set when the scanner input processing ip 4  is activated is confirmed, it may be determined that the image input has been started. 
         [0046]    The scanner input processing ip 4  is started when operation keys  4  are depressed by a user. The scanner input processing ip 4  reads an original by using an image sensor  3   b  of the scanner unit  3  and saves the read image data in the RAM  28  in real time. Upon start of the scanner input, the scanner input processing ip 4  first obtains a value of the horizontal width of the original. The value of the horizontal width of the original is determined either by measuring the size of the original by the image sensor  3   b  or by being specified the size of the original by the user. 
         [0047]    Then, the scanner input processing ip 4  obtains the number of colors and values of resolution of image data to be generated by reading the original. The number of colors and the value of resolution of the generated image data depend on the image output processing op. Alternatively, they are limited in selection range and selected from the range by the user. Finally, the scanner input processing ip 4  notifies the display control processing cp of starting image input. Further, every time the scanner input of the original for one page is terminated, the scanner input processing ip 4  turns an “input termination flag” to ON. Further, every time the scanner input of a new page is started, the scanner input processing ip 4  turns the “input termination flag” to OFF. 
         [0048]    Upon receipt of a notification of starting the image input, the display control processing cp determines to be YES in “image input is started” (S 102  in  FIG. 8 ). A flag may be turned to ON instead of the notification. When it is determined that the image input has been started (S 102 : YES in  FIG. 8 ), the display control processing cp displays image data on the first page at the input content display area of a display  2  and displays the image data in real time (S 103  in  FIG. 8 ). More specifically, the display control processing cp activates input content real-time display processing idp for the scanner input processing ip 4  which displays the image data obtained from an original by the scanner input processing ip 4  on the display  2  in real time. 
         [0049]    The input content real-time display processing idp for the scanner input processing ip 4 , when activated, first obtains information about whether the image input processing ip is used to display image data to be saved in the RAM  28  in real-time. Monitor processing mp monitors which image input processing ip has been activated. Therefore, the information may be obtained from the monitor processing mp, or obtained by confirming an activation flag set when the scanner input processing ip 4  is activated. The display control processing cp may have in advance obtained processing parameter information and the input content real-time display processing idp may obtain the processing parameter information. The input content real-time display processing idp obtains processing parameter information such as the horizontal width, number of colors and resolution of an original which is subjected to the scanner input processing ip 4  to be displayed in real time. The display control processing cp may have in advance obtained processing parameter information from the scanner input processing ip 4 , and the input content real-time display processing idp may obtain the processing parameter information. Alternatively, the input content real-time display processing idp may read out the processing parameter information from a memory (RAM  28  or storage device  24 ) in which the scanner input processing ip 4  stores the processing parameter information, or may inquire to the scanner input processing ip 4 . 
         [0050]    The input content real-time display processing idp calculates how many bytes of data saved in the RAM  28  correspond to one line of the scanner input by referring to the processing parameter information. The input content real-time display processing idp also calculates to what extent the horizontal width the image data is displayed on the display  2  by referring to the processing parameter information. Further, the input content real-time display processing idp calculates how many lines of image data of the scanner input correspond to one line on the display  2  by referring to the processing parameter information. 
         [0051]    Thereafter, the input content real-time display processing idp monitors the number of bytes of the image data saved in the RAM  28  and updates the display by every one display unit. The display unit may correspond to one line unit or several line units. One unit may be defined as every increase in the number of bytes. In this instance, the number of increased bytes is to be calculated and expressed so as to correspond to the number of portions of one line. 
         [0052]    Thereafter, the display control processing cp carries out the scanner input processing ip 4  and sends a notification to the output content real-time display processing odp for the scanner input processing ip 4  by every progress of the scanner input processing ip 4 . A counter may increase its count instead of the notification. 
         [0053]    Next, the display control processing cp determines to be YES in “image output is started” (S 104  in  FIG. 8 ), when facsimile transmission processing op 2  is started at a facsimile transmitting/receiving unit  22 , etc. A notification of the image output start is obtained from the facsimile transmission processing op 2 , by which it is determined that the facsimile transmission processing op 2  has been started. Further, monitor processing mp monitors which image output processing op is activated. Therefore, it may be determined that image output has been started by obtaining information from the monitor processing mp that the facsimile transmission processing op 2  has been activated or by confirming an activation flag set when the facsimile transmission processing op 2  is activated. 
         [0054]    The facsimile transmission processing op 2  starts at the same timing as the start of the scanner input processing ip 4 . When the facsimile transmission processing op 2  is activated, the transmission processing op 2  first obtains information on which image input processing ip is used to output image data to be saved in the RAM  28 . Monitor processing mp monitors which image input processing ip has been activated. Therefore, the information may be obtained from the monitor processing mp, or by confirming an activation flag set when the scanner input processing ip 4  is activated. Next, the facsimile transmission processing op 2  obtains processing parameter information such as the horizontal width, number of colors and resolution of an original processed by the scanner input processing ip 4  which is inputting image data to be output. The facsimile transmission processing op 2  reads out the processing parameter information from a memory (RAM  28  or storage device  24 ) in which the scanner input processing ip 4  stores the processing parameter information, or may inquire to the scanner input processing ip 4 . 
         [0055]    The facsimile transmission processing op 2  calculates how many bytes of data saved in the RAM  28  allows facsimile transmission to start by referring to the processing parameter information. The facsimile transmission processing op 2  turns “output termination flag” to ON, every time an original for one page is completely output. The facsimile transmission processing op 2  turns the “output termination flag” to OFF every time the output of a new page is started. The scanner input processing ip 4  monitors image data to be saved in the RAM  28 , and when the data is sufficiently accumulated to carry out image output start, the facsimile transmission processing op 2  sends a notification of the image output start to the display control processing cp via the monitor processing mp. The flag may be turned to ON instead of the notification. 
         [0056]    When it is determined that image output has been started (S 014 : YES in  FIG. 8 ), an “outputting content display area is displayed and the input/output content is displayed in real time” (S 105  in  FIG. 8 ). The display control processing cp activates output content real-time display processing odp for the facsimile transmission processing op 2  which displays image data output by the facsimile transmission processing op 2  on the display  2  in real time. 
         [0057]    The output content real-time display processing odp for the facsimile transmission processing op 2 , when activated, first obtains information about the resolution from the facsimile transmission processing op 2 . The display control processing cp may have obtained in advance the processing parameter information from the facsimile transmission processing op 2 , and the output content real-time display processing odp may obtain the processing parameter information. Alternatively, the output content real-time display processing odp may read out the processing parameter information from a memory (RAM  28  or storage device  24 ) in which the facsimile transmission processing op 2  stores the processing parameter information, or may inquire for the facsimile transmission processing op 2 . The output content real-time display processing odp calculates how many lines of image data correspond to one line on the display  2  by referring to the processing parameter information. Next, the output content real-time display processing odp obtains information which is notified by the facsimile transmission processing op 2  at the start of facsimile transmission. Then, the output content real-time display processing odp obtains information which is notified by the facsimile transmission processing op 2  every time one-line facsimile transmission is made. Next, the output content real-time display processing odp obtains information which is notified by the facsimile transmission processing op 2  every time one-page facsimile transmission is terminated. It may be monitored whether an output termination flag is turned to ON. 
         [0058]    Specifically, the output content real-time display processing odp for the facsimile transmission processing op 2  obtains processing parameter information (for example, resolution) of the facsimile transmission processing op 2  from the facsimile transmission processing op 2 . And, the output content real-time display calculates by referring to the processing parameter information, how much progress in the facsimile transmission processing op 2  correspond the display  2  to update the display of one line, that is, how many lines of actual images correspond to one line on display (S 201  in  FIG. 9 ). For example, if the facsimile transmission processing op 2  sends a notification by every one predetermined processing unit, calculation is made for how many notifications result in updating of the display. Further, if the facsimile transmission processing op 2  does not send any notification but only has a counter for determining how many bytes of the facsimile transmission processing op 2  are carried out, calculation is made for how many bytes of the facsimile transmission processing op 2  are terminated to result in updating of the display. 
         [0059]    Next, the output content real-time display processing odp for the facsimile transmission processing op 2  determines whether the facsimile transmission processing op 2  has started facsimile transmission (S 202  in  FIG. 9 ). If the facsimile transmission processing op 2  starts the facsimile transmission (S 202 : YES in  FIG. 9 ), the output content real-time display processing odp for the facsimile transmission processing op 2  resets a line counter (S 203  in  FIG. 9 ). Next, the output content real-time display processing odp specifically in the facsimile transmission processing op 2  judges whether one line has been transmitted by facsimile (S 204  in  FIG. 9 ). If one line has been transmitted by facsimile (S 204 : YES in  FIG. 9 ), the output content real-time display processing odp for the facsimile transmission processing opt adds one in the line number counter (S 205  in  FIG. 9 ) and determines whether a value of the line counter has reached a value corresponding to one line on the display  2  (S 206  in  FIG. 9 ). If the value of the line counter has reached the value corresponding to one line on the display  2  ( 3206 : YES in  FIG. 9 ), the output content real-time display processing odp for the facsimile transmission processing op 2  allows the display on the display  2  to proceed by one line (S 207  in  FIG. 9 ) and resets the line number counter (S 208  in  FIG. 9 ). If the value of the line counter does not reach the value corresponding to one line on the display  2  (S 206 : NO in  FIG. 9 ), the output content real-time display processing odp for the facsimile transmission processing op 2  skips the steps S 207  and S 208 . Then, the output content real-time display processing odp for the facsimile transmission processing op 2  determines whether the currently processed page is at termination (S 209  in  FIG. 9 ). If the page is not at the termination (S 209 : NO in  FIG. 9 ), the processing is returned to the step S 204  to repeat the steps S 204  to S 209 . If the page is at the termination (S 209 : YES in  FIG. 9 ), the output content real-time display processing odp for the facsimile transmission processing op 2  determines whether a next page does exist (S 210  in  FIG. 9 ). If the next page exists (S 210 : YES in  FIG. 9 ), the processing is returned to the step S 201  to repeat the steps S 201  to S 210 . If no page exists (S 210 : NO in  FIG. 9 ), the output content real-time display processing odp for the facsimile transmission processing op 2  is terminated. 
         [0060]    Subsequently, the display control processing cp carries out the facsimile transmission processing op 2  and sends a notification to the output content real-time display processing odp by every progress of the facsimile transmission processing op 2 . A counter may increase its count instead of the notification. 
         [0061]    Next, the display control processing cp confirms the input termination flag, thereby determining whether one page is completely input (S 106  in  FIG. 8 ). If one page is not completely input (S 106 : NO in  FIG. 8 ), the display control processing cp confirms the output termination flag, thereby determining whether one page, is completely output (S 111  in  FIG. 8 ). If one page is not completely output (S 111 : NO in  FIG. 8 ), the display control processing cp returns the control to the step S 106 . 
         [0062]    If one page is completely input (S 106 : YES in  FIG. 8 ), the display control processing cp determines whether a next page to be input exists (S 107  in  FIG. 8 ). If the next page to be input does not exist (S 107 : NO in  FIG. 8 ), the display control processing cp turns the processing to the step S 111 . 
         [0063]    If a next page to be input exists (S 107 : YES in  FIG. 8 ), the display control processing cp determines whether such next page input is to be displayed in the outputting content display area (S 108  in  FIG. 8 ). If the next page input is to be displayed in the outputting content display area (S 108 : YES in  FIG. 8 ), the display control processing cp starts to input images of the next page and displays the input at the input content display area (S 109  in  FIG. 8 ) and returns the control to the step S 106 . If the next page input is not to be displayed in the outputting content display area (S 108 : NO in  FIG. 8 ), the display control processing cp changes the input content display area to a plural-page display and starts to input the images of the next page at the bottom page (S 109  in  FIG. 8 ) and returns the processing to the step S 106 . 
         [0064]    On the other hand, when the output termination flag is confirmed, and it is found that one page is completely output (S 111 : YES in  FIG. 8 ), the display control processing cp shifts a completely output page to the output content display area (S 112  in  FIG. 8 ) and determines whether any page does exist at the input content display area (S 113  in  FIG. 8 ). 
         [0065]    If any page exists at the input content display area (S 113 : YES in  FIG. 8 ), the display control processing cp shifts a page which is input earliest in the input content display area to the outputting content display area (S 114  in  FIG. 8 ). And, the processing is returned to the step S 106 , if no page exists at the input content display area (S 113 : NO in  FIG. 8 ), the display control processing cp provides the display  2  as a transmission termination screen and is terminated (S 115  in  FIG. 8 ). 
         [0066]      FIG. 10  illustrates a general flowchart of the output content real-time display processing odp in which the image output processing op is not for the FAX transmission processing op 2 . 
         [0067]    Specifically, the output content real-time display processing odp first obtains processing parameter information (resolution in the case of facsimile) of the image output processing op from the image output processing op and calculates by referring to the processing parameter information how much progress in the image output processing op correspond the display  2  to update the display of one line, that is, how many lines of actual images correspond to one line on display (S 301  in  FIG. 10 ). For example, if the image output processing op sends a notification by every predetermined processing unit, calculation is made for how many notifications result in updating of the display. Further, if the image output processing op does not send any notification but only has a counter for determining how many bytes of the image output processing op are carried out, calculation is made for how many bytes of the image output processing op are terminated to result in updating of the display. 
         [0068]    Then, the output content real-time display processing odp monitors the progress of the image output processing op (S 302  in  FIG. 10 ). In other words, the output content real-time display processing odp obtains information about the progress of the image output processing op. Then, the output content real-time display processing odp determines whether to update the display (S 303  in  FIG. 10 ). In other words, it is determined whether the progress has reached one line on the display  2 . When it is determined that the display should be updated (S 303 : YES in  FIG. 10 ), the output content real-time display processing odp allows the display on the display  2  to proceed by one line (S 303  in  FIG. 10 ). Finally, the output content real-time display processing odp determines whether the image output processing op is terminated (S 305  in  FIG. 10 ). If the image output processing op is not terminated (S 305 : NO in  FIG. 10 ), the processing is returned to the step S 301  to repeat the steps S 301  to S 305 . If the image output processing op is terminated (S 305 : YES in  FIG. 10 ), the output content real-time display processing odp is terminated. 
         [0069]    Next, a description will be given of a transition example of the display on the display  2  of the image processing apparatus  1  according to the first aspect by referring to  FIGS. 11 and 12 . 
         [0070]    At the start of scanner input, as illustrated in (a) of  FIG. 11 , the read image data is displayed in real time. Specifically, a page frame is displayed at the input content display area, and the read image data to be transmitted by facsimile (left-oblique line part) is displayed in the page frame. According to this configuration, with respect to a page on which image input processing is currently performed, a part of the page, on which image input processing has already been performed and a part of the page on which the image input processing has not yet been performed are displayed in different display modes. Herein, the display mode is defined by background color, brightness of the displayed page and so on. For example, the background color of the part, on which image input processing has already been performed is white, and the background color of the part, on which image input processing has not yet been performed is gray. However, the display mode is not limited to them, unless the user can recognize each part of the page by a difference between the display modes. It may be possible to easily understand how far the image input processing of the page has progressed. 
         [0071]    At the start of a facsimile transmission, as illustrated in (b) of  FIG. 11 , image data which has been transmitted by facsimile (right-oblique line part) is displayed, while a part corresponding to the read image data (left-oblique line part) extends in real time. Specifically, a page frame is shifted from the input content display area to the outputting content display area, and image data which has been read and transmitted by facsimile (right-oblique line part) and image data which has been read but not yet transmitted by facsimile (left-oblique line part) are displayed so as to be in contact with each other at the boundary. According to this configuration, with respect to a page on which image output processing is currently performed, a part of the page, on which image output processing has already been performed and a part of the page, on which image output processing has not yet been performed are displayed in different display modes. In addition, with respect to a page on which image input processing is currently performed, a part of the page, on which image input processing has already been performed and a part of the page on which the image input processing has not yet been performed are displayed in different display modes. It may be possible to easily understand how far the image output processing and the image input processing have progressed as a whole process of the image processing. 
         [0072]    When scanner input has reached a next page, as illustrated in (c) of  FIG. 11 , the read image data (left-oblique line part) is further displayed. Specifically, a new page frame is added to the input content display area and image data to be transmitted by facsimile (left-oblique line part) is displayed in the page frame. According to the configuration, a page on which the image output processing is currently performed and a page on which the image input processing is currently performed are displayed at the same time. It may be possible to easily understand how far the image input/output processing has progressed as a whole process of the image processing. 
         [0073]    When facsimile transmission of a page is completed, as illustrated in (d) of  FIG. 11 , a page frame for the page completely transmitted by facsimile (right-oblique line party is shifted to the output content display area, and a page on which the facsimile transmission has finished being performed just before the page on which the facsimile transmission is currently performed is displayed at the output content display area. In addition, a page which is to be transmitted next by facsimile is displayed at the input content display area. According to the configuration, a page on which the image output processing is currently performed and a page on which the image output processing has finished being performed are displayed at the same time. It may be possible to easily understand how far the image output processing has progressed as a whole process of the image processing. Further, the page on which the image output processing is currently performed and the page on which the image output processing has finished being performed are displayed at different positions on the display. It may be possible to compare the page on which the image output processing is currently performed with the page on which the image output processing has finished being performed and also to distinguish them easily. Further, since the page on which the image output processing is currently performed, the page on which the image output processing has finished being performed and either a page on which the image input processing is currently performed or a page on which the image input processing has already been performed and the image output processing has not yet been performed are displayed at different positions. It may be possible to compare the page on which the image output processing is currently performed, the page on which the image output processing has already been performed and either the page on which the image input processing is currently performed or the page on which the image input processing has already been performed and the image output processing has not yet been performed, with one another to distinguish three of them easily. Further, the pages are displayed in the order according to the progress of the image input/output processing. It may possible to easily understand how far a whole process of the image processing has progressed. 
         [0074]    When scanner input is made at a next page, as illustrated in (e) of  FIG. 12 , a page to be transmitted next to the page being transmitted by facsimile is displayed at a top and the scanner input is allowed to proceed. And, a plurality of pages on which the image input processing has already been performed overlaps with one another while being shifted in relation to one another. According to the configuration, a plurality of pages on which the image input processing are currently performed or on which the image input processing has already been performed and the image output processing has not yet been performed are displayed overlapped one another while being shifted in relation to one another. It may be possible to easily understand how many pages on which the image input processing is currently performed or the image input processing has already been performed and on which the image output processing has not been performed exist. Further, the page on which the image output processing is currently performed is compared with a page which is next subjected to image output processing. It may be possible to easily find out a skipped page which is not subjected to image input processing. 
         [0075]    When facsimile transmission is made at a next page, as illustrated in (f) of  FIG. 12 , a page completely transmitted by facsimile is displayed on top of the output content display area, and a next page is displayed at the outputting content display area. In this instance, a page other than the page on top of the output content display area is also at a display mode for a page that is completely transmitted by facsimile. According to this configuration, a page subjected to image output processing just before a page on which the image output processing is currently performed is displayed at a top among a plurality of pages on which the image output processing has already been performed. It may be possible to easily understand how many pages completely subjected to image output processing exist. Further, a page on which the image output processing is currently performed is compared with that subjected to image output processing just therebefore. It may be possible to easily find out a skipped page which is not subjected to image output processing. 
         [0076]    When only one page to be transmitted by facsimile remains, as illustrated in (g) of  FIG. 12 , image input processing is halted and a page on which the image input processing is currently performed does not exist. 
         [0077]    When a page to be transmitted by facsimile does not exist, as illustrated in (h) of  FIG. 12 , a page frame displayed at the input content display area is deleted. 
         [0078]    When facsimile transmission is completed, as illustrated in (i) of  FIG. 12 , a page frame displayed at the outputting content display area is deleted, and consequently, only the content of a page completely transmitted by facsimile remains at the output content display area. 
         [0079]      FIGS. 13A and 13B  are views showing examples of a page displayed on the display. The page displayed on the display is not limited to an image (content) of the page as shown in  FIG. 13A . The page displayed on the display may include information indicating the page in a document to be processed. For example, the page displayed on the display is the number of the page included in a document to be processed as shown in  FIG. 13B . 
         [0080]    The operation according to the first aspect is described as an example of the operation of the facsimile transmission function, that is, in a case where the image input processing ip is the scanner input processing ip 4  and the image output processing op is the facsimile transmission processing op 2 . However, it is a matter of course that the operation of the function in the image processing apparatus  1  is not limited only to the operation of the facsimile transmission function. A description can be given of the operation of the function provided by a combination of any one function of image input processing ip with any one function of image output processing op. For example, in a case of an operation of the copy function, the operation can be described by a combination of the scanner input processing ip 4  with the print output processing op 3 . Further, in a case of the operation of the facsimile receiving function, the operation can be described by a combination of the facsimile receiving processing ip 2  with the print output processing op 3 . 
         [0081]    In other words, the image output processing may include a processing of at least one of a copy output function, a facsimile transmitting function, a print output function, a scanner output function and a portable-medium output function. According to the configuration, it may be possible to easily understand a progress status of the image output processing for the copy output function, facsimile transmission function, print output function, scanner output function and portable-medium output function and also easily find out a skipped page in the image output processing. 
         [0082]    In addition, the image input processing may include a processing of at least one of a copy input function, a facsimile receiving function, a print input function, a scanner input function and portable-medium input function. According to the configuration, it may be possible to easily understand a progress status of the image input processing for the copy input function, facsimile receiving function, print input function, scanner input function and portable-medium input function and also easily find out a skipped page in the image input processing. 
         [0083]    According to aspects of the invention, a status of two or more types of processing for the operation of one function may be confirmed by displaying a page on which image output processing is currently performed on a display and also displaying a part of the page on which the image output processing has already been performed and a part of the page on which the image output processing has not yet been performed in different display modes in real time. 
         [0084]    Description has been so far given of aspects of the present invention, which are, however, only examples. The present invention is not limited thereto and may be modified in various ways on the basis of knowledge of a person skilled in the art, as long as not departing from the gist of the scope of the claims.
