A process instruction area 53, a document filing process instruction area 54 for accepting specification of a document filing process, and a network transmission process instruction area 55 for accepting designation of a network transmission process are displayed. When any of these areas is touched by the user, the setting processing unit 21d determines that the data processing corresponding to the touched area is data processing instructed to be executed by the user. When the user intends to execute a plurality of data processes in parallel, the user touches a plurality of areas corresponding to each data process on the data process reception screen 50.

  Returning to the description of FIG. 5, after the process of step S <b> 202, the process execution control unit 21 h determines whether the data process specified by the user includes a network transmission process, an e-mail transmission process, or a facsimile transmission process. Is determined (step S203). If the data processing includes network transmission processing, e-mail transmission processing, or facsimile transmission processing (YES in step S203), the process execution control unit 21h receives the network transmission processing, electronic transmission via the input unit 11. Information on the transmission destination of the mail transmission process or the facsimile transmission process is received from the user, and the transmission destination is set using the information (step S204).

  FIG. 8 shows an e-mail transmission process setting screen 60 that is displayed when the e-mail transmission process is designated by the user on the data process acceptance screen 50. The e-mail transmission processing setting screen 60 displays an address book display instruction area 61. When the address book display instruction area 61 is touched by the user, an address book display screen 70 is displayed.

  Further, when one of the registered destinations is touched by the user on the address book display screen 70, a destination detail display screen 80 showing the detailed information of the destination is displayed as shown in FIG. When the user touches an e-mail address on the destination details display screen 80, the e-mail destination is set to the touched e-mail address. On the destination detail display screen 80, when a telephone number is touched by the user, a destination for facsimile transmission is set to the touched telephone number.

  Further, when the name of an external device such as a personal computer is touched by the user on the address book display screen 70 shown in FIG. 8, the same detailed information as the destination detailed display screen 80 shown in FIG. When the address is touched by the user, a network transmission destination is set to the touched address.

  Here, the user can set one or more destinations for each of the network transmission process, e-mail transmission process, and facsimile transmission process to be executed via the address book display screen 70 shown in FIG. . When the destination is set, as shown in FIG. 9, the display is switched again to the e-mail transmission process setting screen 60.

  Returning to the description of FIG. 5, when the process of step S204 is executed, or when the data process does not include the network transmission process, the e-mail transmission process, or the facsimile transmission process in step S203 (in step S203). In the case of NO), the setting processing unit 21d receives, from the user, designation of whether or not to perform data processing by excluding a blank page via the input unit 11, and based on the designation, blank page exclusion processing Whether or not to perform is set (step S205).

  FIG. 9 shows a blank page exclusion instruction acceptance screen 100 that accepts an instruction from the user as to whether or not to perform blank page exclusion processing in the email transmission process. The blank page exclusion instruction acceptance screen 100 is a screen that is displayed when the user touches the blank page exclusion function selection area 91 for displaying the blank page exclusion instruction acceptance screen 100 on the function display screen 90. The function display screen 90 is a screen displayed when the function selection area 62 is touched by the user on the e-mail transmission process setting screen 60.

  In this blank page exclusion designation receiving screen 100, a blank page exclusion instruction area 101 for instructing to perform a process of excluding a blank page is displayed, and this blank page exclusion instruction area 101 is touched by the user In addition, the setting processing unit 21d determines that an instruction to exclude a blank page has been received from the user.

  When the user receives an instruction to perform blank page exclusion processing, the blank page exclusion setting data 15b stored in the storage unit 15 is read, and the blank page is excluded from the blank page exclusion setting data 15b. For the data processing set as the data processing to be performed, data processing excluding blank pages is performed. Here, if there is no data processing set as data processing performed by excluding the blank page in the blank page exclusion setting data 15b, the blank page exclusion instruction area 101 is touched by the user, and blank page exclusion processing is performed. Even if the designation to perform the operation is received from the user, the data processing excluding the blank page is not performed.

  Returning to the description of FIG. 5, after step S205, the scheduling processing unit 21e reads one page of image data stored as image data 15a in the storage unit 15 as a page to be processed (step S206). Further, the scheduling processing unit 21e reads the image attribute data 15c from the storage unit 15, and acquires information on whether or not the image data is a blank page (step S207).

  Then, the scheduling processing unit 21e determines whether one of the data processes performed in parallel is a data process that excludes a blank page (step S208). More specifically, the scheduling processing unit 21e receives a designation for excluding a blank page from the user in step S205, and the blank page exclusion setting data 15b performs a blank page exclusion process. When the data processing is set in advance, it is determined that the data processing is data processing performed by excluding a blank page. In other cases, the scheduling processing unit 21e determines that the data processing is not data processing that excludes blank pages.

  Then, when the data processing is data processing that performs blank page exclusion processing (YES in step S208), the scheduling processing unit 21e determines whether or not the page to be processed is a blank page ( Step S209). If the page to be processed is a blank page (YES in step S209), the scheduling processing unit 21e excludes the blank page to be processed from the image data (step S210).

  Thereafter, the scheduling processing unit 21e determines whether there is a data process that is not a target of the determination process in Step S208 among the plurality of data processes designated to be performed in parallel by the user (Step S208). S211). In step S208, if the data processing is not data processing for performing blank page exclusion processing (NO in step S208), if the page to be processed is not a blank page in step S209 (NO in step S209). In this case, the scheduling processing unit 21e executes the process of step S211. If there is a data process that is not the object of the determination process in step S208 (YES in step S211), the process proceeds to step S208, and the subsequent processes are executed for the data process.

  When there is no data processing that is not the target of the determination processing in step S208 (in the case of NO in step S211), as shown in FIG. 6, the scheduling processing unit 21e, for each page of the image data read so far, A scheduling process for rearranging the order is executed (step S212). However, if the order of each page is correct, this scheduling process is not performed.

  Thereafter, the image editing processing unit 21f executes an image editing process for consolidating the pages of the image data read so far on one side of the sheet, and enlarging or reducing the images included in each page (step S213). ). However, when image editing is not necessary, this image editing process is not performed. Then, the image editing processing unit 21f stores the image data edited by the image editing processing, and if the image editing processing is not performed, the unedited image data is stored as the edited image data 15e in the storage unit 15 (step S214). .

  Thereafter, the preview image generation unit 21g determines whether or not the user has instructed to execute the preview display in step S201 in FIG. 5 (step S215). When the user instructs to execute the preview display (YES in step S215), the preview image generating unit 21g reads out the thumbnail image stored as the thumbnail image data 15d in the storage unit 15 (step S216).

  Subsequently, the preview image generation unit 21g generates image data of the document display preview screen 30 shown as an example in FIG. 2 using the read thumbnail image (step S217). Then, the preview image generation unit 21g displays the document display preview screen 30 on the display unit 12 using the generated data (step S218).

  Thereafter, the display switching unit 21i determines whether or not an instruction to switch the display from the document display preview screen 30 to the finished display preview screen 40 shown in FIG. 3 is received from the user (step S219). For example, the display switching unit 21i detects whether or not the finished display instruction area 33 in FIG. 2 has been touched by the user, and performs the above determination.

  When an instruction to switch the display is received from the user (YES in step S219), it is checked whether or not the data process to be executed includes a process performed by excluding a blank page (step S220). When the data processing to be executed includes processing performed by excluding a blank page (YES in step S220), the preview image generation unit 21g performs data processing performed by excluding the blank page as shown in FIG. The image data of the finished display preview screen 40 excluding the thumbnail image of the blank page is generated (step S221). Then, the display unit 12 displays the generated finish display preview screen 40 (step S223).

  In step S220, when there is no process performed by excluding the blank page in the data process to be executed (NO in step S220), the preview image generating unit 21g uses the thumbnail image of the blank page for all the data processes. The image data of the finished display preview screen 40 including it is generated (step S222). Then, the display unit 12 displays the generated finish display preview screen 40 (step S223).

  Thereafter, as shown in FIG. 7, the process switching unit 21 j gives an instruction to switch the data process to be executed (document filing process, network transmission process, print process, e-mail transmission process, or facsimile transmission process). It is determined whether or not it has been accepted from the user via step S224 (step S224).

  Further, when the user has not instructed to execute the preview display in step S215 in FIG. 6 (NO in step S215), or when the user has not received an instruction to switch the preview display in step S219 ( In the case of NO in step S219), the determination process in step S224 is also executed.

  When an instruction to switch data processing to be executed is received from the user (YES in step S224), the process proceeds to step S202 in FIG. 5, and the setting processing unit 21d performs data processing to be executed from the user via the input unit 11. Is accepted (step S202), and the subsequent processing is executed.

  In this case, image data of the finished display preview screen 40 including a thumbnail image of data processing newly designated by the user is generated, and the finished display preview screen 40 is displayed. Thereby, the user can re-select the data processing at any time, and can easily confirm the final configuration of each page of the image data to be processed.

  In step S224 of FIG. 7, when an instruction to switch the data processing to be executed is not received from the user (NO in step S224), the process execution control unit 21h determines whether or not the data processing to be executed is a facsimile transmission process. (Step S225).

  If the data process to be executed is not a facsimile transmission process (NO in step S225), the process execution control unit 21h executes each data process such as a document filing process, an image data transmission process, a printing process, and an e-mail transmission process. The processing unit that has transmitted the image data to the processing unit and received the image data corresponds to one page of image data including a blank page according to the setting information stored as blank page exclusion setting data 15b in the storage unit 15. Or data processing for one page of image data excluding blank pages (step S226).

  However, this data processing is executed when execution of the data processing is instructed by the user. For example, FIG. 10 shows a process in which the user excludes a blank page on the blank page exclusion process setting screen 100 (blank page exclusion process setting screen 100 shown in FIG. 9) displayed in the process of step S205 of FIG. An e-mail transmission process setting screen 60 that is displayed again after an instruction to do so is shown. In the e-mail transmission process setting screen 60, when the process execution start instruction area 63 is touched by the user, the execution of the process of step S226 and step S230 described later is started.

  In addition, when the destination confirmation area 64 is touched by the user on the e-mail transmission processing setting screen 60, the destination list screen 110 is displayed on the display unit 12. In this example, since the e-mail transmission process and the facsimile transmission process are selected as the data processing performed in parallel, the e-mail transmission destination and the facsimile transmission destination are displayed on the destination list screen 110. The

  Further, when the detail display instruction area 111 displayed for each address on the destination list screen 110 is touched by the user, a setting detail display screen 120 that displays details of the destination setting corresponding to the touched detail display instruction area 111. Is displayed on the display unit 12. When the setting change instruction area 121 displayed on the setting details display screen 120 is touched by the user, the display is switched to the e-mail transmission processing setting screen 60, and the destination can be changed. In each function such as e-mail transmission and facsimile transmission, information as to whether or not to exclude a blank page is preset for each function and for each destination, and the setting information is stored as blank page exclusion setting data 15b. Stored in the unit 15. The information is displayed in the special function column of the setting details display screen 120.

  Further, the processing execution control unit 21h may set the resolution for each function such as e-mail transmission and facsimile transmission and for each destination. In this case, the storage unit 15 stores the resolution information in advance in association with each function and each destination, and the process execution control unit 21h reads the information and performs image processing on the image data to be processed. Set the resolution. The information is displayed in the resolution column of the setting details display screen 120. When the resolution is set by the process execution control unit 21h, each data process is executed at the resolution.

  When the destination list screen 110 or the destination detail display screen 120 is closed, as shown in FIG. 11, the display is switched again to the e-mail transmission process setting screen 60, and the process execution start instruction area 63 is touched by the user. In this case, the execution of the process of step S226 and step S230 described later is started. That is, it is determined based on the information stored as the blank page exclusion setting data 15b whether the data process to be executed is a data process performed by excluding a blank page or a data process performed including a blank page. Depending on the determination result, data processing is performed on the image data 130 excluding the blank page or the image data 140 including the blank page.

  Further, when the user touches the process execution start instruction area 34 on the document display preview screen 30 (document display preview screen 30 shown in FIG. 2) displayed in step S218 in FIG. 6, the display is performed in step S223 in FIG. In the finished display preview screen 40 (finished display preview screen 40 shown in FIG. 3), even when the process execution start instruction area 34 is touched by the user, the process of step S226 and the process of step S230 described later are executed. Be started.

  Note that in step S213 in FIG. 6, when image editing processing is performed in which a plurality of pages are aggregated into one page, until one page of image data in which the plurality of pages are aggregated is generated, in FIG. Data processing for the page read in step S206 is not executed. Also, in step S210 in FIG. 5, even when the blank page read out in step S206 in FIG. 5 is excluded, data processing performed by excluding the blank page is not executed for the excluded blank page. As for the facsimile transmission process, the transmission process is performed when all the pages of the image data are ready (step S230 described later).

  Further, when the execution instruction of the data processing is not yet input by the user at the time of executing the processing of step S226, the processing may be interrupted until the input is made, or after step S227. The processing may be executed first, and the data processing may be executed when input is made by the user.

  After the process of step S226, or when the data process to be executed is a facsimile transmission process in step S225 (YES in step S225), the process execution control unit 21h is still a target of the determination process of step S225. It is determined whether there is any unprocessed data (step S227). If there is a data process that is not the object of the determination process (YES in step S227), the process proceeds to step S225, and subsequent processes are executed for the data process that is not the object of the determination process. Is done.

  In step S227, when there is no data processing that is not the target of the determination processing in step S225 (NO in step S227), the process execution control unit 21h determines that the page read in step S206 in FIG. It is determined whether or not the current page (step S228). If the page is not the last page of the image data (NO in step S228), the process proceeds to step S206 shown in FIG. 5, and the scheduling processing unit 21e reads the next page of the page for one page (step) S206). Thereafter, the subsequent processing is executed.

  If the page read in step S206 in FIG. 5 is the last page of the image data (YES in step S228), the process execution control unit 21h performs the facsimile transmission process in the data process executed in parallel. It is determined whether or not it is included (step S229). When the facsimile transmission process is included in the data processing executed in parallel (YES in step S229), the process execution control unit 21h stores the setting stored as the blank page exclusion setting data 15b in the storage unit 15. Depending on the information, a facsimile transmission process including a blank page or a facsimile transmission process excluding the blank page is executed (step S230). Thereafter, the data processing of the image data ends. If the facsimile transmission processing is not included in the data processing executed in parallel (NO in step S229), the data processing of this image data is finished as it is.
