  The operation panel unit 103 includes a touch panel, a numeric keypad, a start button, a stop button, and the like, and is used for displaying various information and inputting various instructions.

  The ADF 104 sequentially conveys a plurality of originals including the set tab sheets to a predetermined reading position of the image reading unit 105 one by one, and sequentially discharges the originals after image reading.

  The image reading unit 105 irradiates the original set at a predetermined reading position or the original conveyed to the predetermined reading position by the ADF 104 with a light source such as a fluorescent lamp, and reflects the reflected light to an imaging device such as a CCD image sensor. The image data is generated from the electrical signal.

  The paper feeding unit 106 accommodates paper as a recording material used for printing. The sheet feeding unit 106 sends out the stored sheets one by one to the image forming unit 107. The image forming unit 107 prints various data on a sheet using a known image forming process such as an electrophotographic process including charging, exposure, development, transfer, and fixing processes.

  The image processing unit 108 separates the character image region, the graphic image region, and the photographic image region from the image data read by the image reading unit 105, and performs appropriate image processing on each region. Further, the image processing unit 108 combines the areas based on the position information, creates a document file in the internal file format, and converts the document file into a PDF file.

  The MFP 100 includes a communication interface, and includes a transmission / reception function for exchanging data such as a created PDF file with an external device such as a personal computer (PC) or a portable terminal, and a copy function for copying a document.

  FIG. 2 is a block diagram functionally showing the configuration of the image reading apparatus.

  As shown in FIG. 2, the image reading apparatus 200 includes a CPU 21, a ROM 22, a RAM 23, a hard disk (HDD) 24, an operation panel unit 25, an image processing unit 26, and a document reading unit 27, which exchange signals. Connected to each other via a bus.

  The CPU 21 shows a part of the functions of the control unit 101, and controls each part of the image reading apparatus 200 and performs various arithmetic processes according to a program. The ROM 22 stores various programs and parameters for controlling basic operations of the image reading apparatus 200.

  The RAM 23 temporarily stores programs and data as a work area. In the RAM 23, an area for storing whether or not the PDF data includes image data of the tab sheet main body by the operation panel unit 103 and image data read by the document reading unit 27 are temporarily stored. An area and an area for storing a table of contents table generated based on the page where the tab sheet is detected are secured. In the hard disk (HDD) 24, an area for storing data of a standard document size prepared in advance and an area for storing the generated PDF file are secured.

  The operation panel unit 25 shows a part of the functions of the operation panel unit 103, and has a function of setting whether or not the image data of the tab sheet main body is included in the PDF file. The document reading unit 27 includes an ADF 104 and an image reading unit 105. The document reading unit 105 continuously reads a document set on the ADF 104 to generate image data, and operates when there is no document set on the ADF 104. To stop.

  FIG. 3 is a diagram illustrating an example of a read document including a tab sheet.

  The read original is composed of 10 standard-size originals and 3 tab sheets, and is composed of 13 pages. That is, a tab sheet is arranged at the head, then three standard-size originals, tab paper, four standard-size originals, tab paper, and three standard-size originals are arranged in this order.

  This tab sheet represents each chapter of the manuscript, the first tab sheet represents chapter 1, chapter 1 is composed of 4 pages, the next tab sheet represents chapter 2, and chapter 2 is composed of 5 pages. The next tab sheet represents chapter 3, and chapter 3 is composed of four pages.

  Each of the tab sheets includes a rectangular main body and a protruding tab provided at a predetermined position on one side of the main body. In this example, an index number is assigned to the tab of the tab sheet as a character string representing a chapter.

  This tab sheet is a set of tab sheets composed of three components and is referred to as three tabs. Tab sheets are also called index sheets. In the example of FIG. 3, the order of tab sheets is called normal order, and when the tabs are positioned on the right side of the main body, the upper tabs are arranged so that they are positioned on the upper side of FIG. In the case of a 3-tab tab sheet, each tab is provided at a position lowered in three stages from the top of one side of the main body. Tab sheets are usually stacked for a plurality of sets and set in a predetermined paper feed tray.

  FIG. 4 is a diagram for explaining a method of detecting a tab sheet.

  The document reading unit 27 reads a document line by line in the main scanning direction (from left to right in the figure). It is detected whether or not there is a protrusion at the trailing edge of the document, and it is determined whether or not the detected protrusion is continuous. As a result, when the protruding portion exists, it is determined that the read document is a tab sheet, and when the protruding portion does not exist, it is determined that the read document is a standard size document.

  Next, when a tab sheet is detected, the main body of the tab sheet and the tab sheet are separated, and a table of contents table in which the table of contents page and the character string of the headline are associated with each other is generated. The table of contents table is stored in the RAM 23 of the image reading apparatus 200 and is referred to when generating the table of contents page of the PDF file.

  In the example of FIG. 3, when the main body of the tab sheet is included in the manuscript page, the first page of the manuscript as the table of contents page is associated with the table of contents character string “Index1”, and the fifth page of the manuscript as the table of contents page is displayed. The table of contents character string “Index2” is associated, and the table of contents character string “Index3” is associated with the 10th page of the document as the table of contents page.

  When the main body of the tab sheet is not included in the manuscript page, the table of contents character string “Index1” is associated with the first page of the manuscript as the table of contents page, and the table of contents characters are displayed on the fourth page of the manuscript as the table of contents page. The column “Index2” is associated, and the table of contents character string “Index3” is associated with the ninth page of the document as the table of contents page.

  As a method of separating the tab sheet main body and the tab, information on the size of a standard document (A4, A3, letter, tabloid, etc.) is stored in advance, and the standard document closest to the size of the tab sheet image data. , There is a method for determining that a portion that fits into the size of the standard document is the main body and that the remaining image data that does not fit is a tab. There is also a method of determining when the document reading unit reads a document by specifying in advance the size of the tab sheet and the document reading method.

  5 and 6 are diagrams illustrating a description example of the data structure of the PDF file.

  The PDF file is composed of four elements: a header, a body, a cross reference table, and a trailer.

  The header (% PDF-1.6) specifies version information of the PDF specification to which the file complies. In the body, an object constituting the document stored in the file is described. In the cross reference table, information about indirect objects in the file is described, but the description is omitted here. The trailer includes an end-of-file symbol (%% EOF) and indicates the location of the cross-reference table and some special objects within the body of the file.

  Here, the body expressing each page of the PDF file will be described in detail. 5 and 6, the display contents of the first to third pages and the table of contents page of the read document are described in the body.

An object 1 (an object indicated by “1 0 obj”. “** 0 obj” is hereinafter referred to as an object **) is a page object (Type / Page), and specifies an attribute of a single page of a document. Also, object 1 is clipped when the dictionary (Resources 2 0 R) containing the resources required by the page, the page tree node (Parent 19 0 R) that is the parent of this node, or when the page content is displayed or printed. Object 2 (CropBox [0 0 595.22 842]), the maximum outputable area (MediaBox [0 0 595.22 842]) of the physical medium that is the print destination of the page, etc. Define a dictionary. In this example, the object 2 has a color space (ColorSpace << / Cs6 32 0 R >>) in which color values are expressed, and a font dictionary (Font << TT 1 30 0 R / TT 4 13 0 R / TT 6 11) to be referred to. 0 R >>), a predefined procedure set name (ProcSet [/ PDF / Text]) that is interpreted when printing to the PostScript output device, a parameter dictionary (ExtGSState << GS1 35 0 R) of the graphic state (GS1) >).

  The object 3 is a stream object, and is composed of a dictionary describing stream data (a sequence of bytes) and subsequent stream data. In this example, the number of bytes of stream data (Length 169), a filter name (Filter / FlateDecode) applied to stream data processing, and stream data (stream and Endstream data) are defined. Note that stream data is omitted.

  In this way, the first page of the document is represented by the page object described in the objects 1 to 3, the page resource dictionary, and the stream object. Similarly, the second page of the document is represented by a page object described in the objects 4 to 6, a page resource dictionary, and a stream object, and the third page of the document is a page object described in the objects 7 to 9, Represented by a page resource dictionary and stream object.

  An object 24 is a page object (Type / Page) and represents a table of contents page. Similar to the objects 1, 4, and 7, the object 24 defines a dictionary including resources required by the page, a page tree node, a clipping area, a maximum printable area of the physical medium on which the page is printed, and the like. In addition, an annotation object expressing an annotation related to the page is designated by an object number 25 (Annots 25 0 R). The annotation function associates the object with a location on the page of the PDF document and can interact with the user through a mouse or keyboard, which updates the page object.

  The object 25 is an array object ([26 0 R 27 0 R 28 0 R]), and specifies the object number to be annotated. In other words, the annotation dictionary to be referred to as the annotation object is designated as the object numbers 26, 27, and 28.

  Object 26 is an annotation dictionary. The annotation type is a link annotation (Subtype / Link), which represents a hypertext link (jump) to a destination at another location in the document. The annotation location (Rect [56.4159 753.062 542.92 767.0]) on the page is defined in units of the default user space. The A entry (A 42 0 R / H / I) represents an action to be executed when an annotation is activated. That is, in this example, when the mouse button is pressed or kept pressed in the annotation active area (BS << / S / SW 0 / Type / Border >>), the program jumps to the object number 42. Similarly, it is described that the object 27 jumps to the object number 43 and the object 28 jumps to the object number 44.

  An object 37 is a stream object, and is composed of a dictionary describing stream data and subsequent stream data.

  An object 42 is a Go-to action (S / GoTo) and indicates a destination of a jump destination. In this example, a jump is made to the first page of the document described by object number 1. That is, when the mouse button is pressed in the active area of the annotation, the program jumps to the object 42 (object 26), and the first page of the document described by the object number 1 is displayed (object 42). Similarly, the object 42 describes jumping to the second page of the document described by the object number 4, and the object 43 describes jumping to the third page of the document described by the object number 7.

  An object 19 is a page tree (Type / Pages), which defines the order of pages in a document and connects individual pages to constitute a page of a PDF file. In this example, it is described that there is a page tree of a 4-page document (Count 4). Further, the pages in the document are positioned in the order of the pages described by the object numbers 24, 1, 4, and 7. That is, the PDF file includes pages in the order of the index page, the first page of the document, the second page of the document, and the third page of the document.

  Thus, the table of contents page is displayed on the first page of the PDF file. On the table of contents page, when the table of contents item (active area of annotation) is clicked with the mouse button, the page of each document linked to the table of contents item is displayed.

  FIG. 7 is a flowchart illustrating a processing procedure in the image reading apparatus.

  The original set on the original reading unit 27 is read (step S101). The document reading unit 27 sequentially conveys the document on which the ADF 104 is set to the image reading unit 105 one by one, and the image reading unit 105 continuously reads and generates image data.

  It is determined whether or not the generated image data is the first page (step S102). If it is determined that the image data is the first page (S102: Yes), a PDF file is generated and a header is written (step S103). When the image reading apparatus 200 reads the first document among a plurality of documents, the image reading device 200 generates a PDF file on the HDD 24, specifies the version information of the PDF specification, and writes the header.

  A table of contents table is generated (step S104), and the process proceeds to step S105. The image reading apparatus 200 generates the above-described table of contents on the RAM 23.

  On the other hand, if it is determined in step S102 that it is not the first page (S102: No), it is determined whether or not there is a protrusion on the trailing edge of the document (step S105). As described above, the image forming apparatus 200 determines whether the document is a tab sheet or a standard size document depending on whether or not a protruding portion is present at the trailing edge of the document.

  That is, when the original is first read, the image reading apparatus 200 generates a PDF file and a table of contents, and determines whether the sheet is tab paper. On the other hand, when the second and subsequent pages are read, it is determined whether or not it is a tab sheet as it is.

  If it is determined that there is a protrusion at the trailing edge of the document (S105: Yes), the read image data is compared with the standard document size (step S106). The image reading apparatus 200 reads data of a standard document size from the HDD 24 and compares it with the read image data recorded in the RAM 23.

  The read image data is separated into a main body and a tab portion (step S107). The image reading apparatus 200 compares the data of the standard document size with the read image data by the above-described method, thereby separating the tab sheet image data into the main body and the tab and storing them in the RAM 23.

  It is determined whether the setting includes the main body of the tab (step S108). The image reading apparatus 200 reads the setting by the operation panel unit 103 as to whether or not the image data of the tab sheet main body is included in the PDF file from the RAM 23, and determines whether or not the setting includes the tab main body.

  If it is determined that the setting does not include the main body of the tab (S108: No), the process proceeds to step S110. On the other hand, if it is determined that the setting includes the main body of the tab (S108: Yes), the image data of the main body is added to the PDF file as the next image page (step S109).

The image data of the tab part is recognized (step S110). The image reading apparatus 200 recognizes the image data of the tab portion of the tab sheet separated in step S107. As a method of character recognition, for example, a method of discriminating based on the degree of matching between the feature amount of each character image and a dictionary pattern stored in advance can be used. Page number and tab portion recognized in step S110 Is stored in the table of contents table (step S111), and the process proceeds to step 113. The image reading apparatus 200 writes the page number and the character string of the tab portion in the table of contents generated in step S104.

  On the other hand, if it is determined in step S105 that there is no protrusion at the trailing edge of the document (S105: No), image data is added to the PDF file (step S112), and the process proceeds to step 113.

  That is, when the document is a tab sheet, the image reading apparatus 200 adds the image data of the tab sheet main body to the PDF file according to the setting, and stores the page number and the character string of the tab part in the character table. On the other hand, if the document is not a tab sheet, the image data is added to the PDF file as the next document page.

  It is determined whether it is the last page (step S113). The image reading apparatus 200 determines whether or not the original set on the ADF 104 by the original reading unit 27 is lost. If it is determined that the page is not the last page (S113: No), the process returns to step S101, and the next original reading process is performed.

  On the other hand, when it is determined that the page is the last page (S113: Yes), a table of contents object of the PDF file is generated based on the table of contents table (step S114). The image reading apparatus 200 finishes writing the original page of the PDF file and starts generating the table of contents page.

  The table of contents object generated in step S114 is added to the PDF file (step S115). The image reading apparatus 200 adds a table of contents object as the table of contents page of the PDF file.

  A footer is written in the PDF file (step S116), and the process ends. The image reading apparatus 200 adds a trailer as a footer of the PDF file.

  That is, the image reading apparatus 200 reads the document up to the last page, and then generates and appends a table of contents page of the PDF file based on the table of contents table. As described above, the added table of contents table is displayed on the first page using the page tree structure of PDF.

  As described above, according to the present embodiment, when a plurality of documents including tab sheets are read and an image file is created, a character string in the tab portion is used as a table of contents item, and the table of contents in which the tab sheet is detected is included in the table of contents item. A page can be generated. Furthermore, an image file having the table of contents page as the first page can be created. By doing so, the user can acquire an image file with a table of contents page divided into chapters by tab sheets when reading a plurality of originals including tab sheets.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims.

  In the above embodiment, whether or not to include the image data of the tab sheet main body in the PDF file is set by the operation panel unit 103. If the setting includes the main body of the tab, the image data of the tab sheet main body is the next image. Although added as a page (step S109), the present invention is not limited to this. When a tab sheet is detected as a read document, the image data of the tab sheet main body is not recognized as a page, and the next image data can be added to the PDF file as the next image page.

  By doing so, setting by the operation panel unit can be omitted, and input by the user becomes unnecessary. Also in the processing by the image reading apparatus, the processing for determining whether the setting includes the main body of the tab sheet can be omitted, and the processing can be simplified.

  In the above-described embodiment, the image reading apparatus is realized by being incorporated in MFP 100, and constitutes a part of the function of MFP 100. However, the present invention is not limited to this. The image reading apparatus of the present invention includes an original reading unit and an image processing unit, and can be realized by a single device if it can read a plurality of originals including tab sheets and create an image file. It may be incorporated in other devices.

  Further, the processing in the image processing apparatus of the present embodiment can be realized by either a dedicated hardware circuit or a programmed computer. The program may be provided by a computer-readable recording medium such as a flexible disk or a CD-ROM, or may be provided online via a network such as the Internet. In this case, the program recorded on the computer-readable recording medium is usually transferred to and stored in a storage unit such as a hard disk. The program may be provided as a single application software, or may be incorporated into the software of the device as one function of the device.
