Description

  The present invention relates to an image processing apparatus, and more particularly to an image processing apparatus that reads a book document.

  Conventionally, since a platen provided in an image processing apparatus is a flat glass plate, when a sheet-like document is set, the document easily comes into close contact with the platen surface, thereby obtaining a clear read image. be able to.

  However, when there is a binding portion at the center as in a book-like document, the binding line is lifted, and there is a problem that reading is performed in a state where the entire reading surface of the document is not in close contact with the platen. .

  Further, there arises a problem that a read image of a portion that is not in close contact with the upper surface of the platen becomes unclear, reduced, or darkened. Further, when the book or the like is opened to the horizontal state, the spine portion may be bent greatly and damaged, and the binding portion may be adversely affected.

Therefore, there is a technology in which an edge is formed on one end of the platen by the end surface of the platen and the surface on the apparatus side, the book document is bound to the edge and set in a spread state, and the book document is read clearly. It has been proposed (see Patent Document 1).
JP 2000-165617 A

  However, in the above-described prior art, for example, after reading the left side of the original document facing the book document in the spread state, when trying to read the right side of the original document, the edge that aligns the binding of the book document has a platen edge. Therefore, the book document must be rotated 180 °, set and read.

  It is very troublesome for the user who uses the apparatus to take this procedure, and it is inferior in terms of reading operability.

  In view of the above-described problems, an object of the present invention is to improve the readability of a book document.

  The present invention is premised on an image processing apparatus that reads a document set on a platen constituting a scanner.

  In the present invention, edge portions for aligning the stitches of a book document are formed at both end positions of the platen.

  In this way, edge portions for setting the stitches of the book document can be formed at both ends of the platen, and the book document is set on the edge portion of one end portion so that one side of the book document in a spread state is formed. read. Thereafter, the other side can be read simply by sliding the book original to the edge part of the other end, and thus the readability of the book original in the spread state is improved.

  The edge portion may be configured such that the surface of the apparatus main body is inclined downward from the position of the platen end toward the end.

  In addition, the edge portion may be formed by a surface perpendicular to the platen on the side surface of the apparatus main body from the position of the platen end.

  In this way, the degree of adhesion between the document surface of the book document and the platen increases, and a clearer image can be read.

  Further, a document size sensor that detects the document size with reference to each of the edge portions at both ends of the platen may be provided.

  In this way, since the paper size can be detected based on each of the edge portions, reading can be performed regardless of which edge portion the book original is set.

  By forming edge portions for setting the stitches of the book document at both ends of the platen, the operability of reading the book document in the spread state is improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic diagram showing a configuration of an image processing apparatus according to an embodiment of the present invention, and FIG. 2 is a functional block diagram of the image processing apparatus according to an embodiment of the present invention. In the present embodiment, a case where a book document is used as a document will be described.

  A scanner 2 is provided on the upper part of the apparatus main body 1, and the original is read by moving the entire surface of the original set on the platen 3 within a necessary range of scanning, as in the case of a scanner generally used conventionally.

  Edge portions 5a and 5b having obtuse angles are formed at both ends of the platen 3 constituting the scanner 2 by inclined surfaces 4a and 4b obtained by inclining the surface of the apparatus main body 1 downward from the end position of the platen 3 toward the end. doing. A white reference plate is disposed on the back surface of the inclined surfaces 4a and 4b of the apparatus body 1.

  Therefore, the surface of the book original A such as a thick book is opened at an obtuse angle in a spread state and pressed against the edge portion 5a or 5b to bring the reading surface into close contact with the platen 3 and do not perform reading. The document can be set in a stable state by being in close contact with the side inclined surface 4a or 4b of the apparatus main body 1. In addition, it is good also as a structure which forms the edge parts 5a and 5b in the perpendicular | vertical surface with respect to the surface of the said platen 3 from the edge part of the said platen 3, and the inclination angle is 90 degrees.

  Further, as shown in FIG. 3, the lower surface of the platen 3 is composed of original detection sensors 6a and 6b for detecting the original setting state, and a plurality of originals for detecting the size of the original with reference to the edges 5a and 5b. A document size sensor 7 (see FIG. 2) is provided.

  With the above configuration, reading is performed by opening the book document so that the binding is positioned on the edge portion 5a or 5b formed between the end portion of the platen 3 and the inclined surfaces 4a and 4b of the apparatus main body 1. The document surface can be set flat and the stitches can be read clearly.

  Next, the operation status from setting the original to reading the image will be described in detail with reference to FIG.

  First, when a user sets a book document on the upper surface of the platen 3 and prints a double-sided spread image of the book document on one sheet of paper, the mode setting means 8 sets the book mode and turns on the start key ( S1). In addition, when outputting an image of only one of the left and right sides without synthesizing a double-sided spread image on one sheet, the output is performed in the same manner as when outputting a normal page document without setting the book mode. .

  When the start key is turned on, the original detection sensors 6a and 6b are activated to detect whether or not the position where the book original is set is set on the left edge 5a as viewed in the drawing (see FIG. S2).

  When a document is set on the left edge portion 5a, the document size sensor 7 is activated to detect the document size with reference to the left edge portion 5a (S3). As a result, a paper having a size twice that of the paper corresponding to the detected size is selected.

  On the other hand, when the document is not set on the left edge portion 5a, it is detected whether or not the document is set on the right edge portion 5b (S2 → S4).

  In the detection process S4, when it is detected that a document is set on the right edge portion 5b, the document size sensor 7 detects the document size with reference to the right edge portion 5b (S4 → S5). The paper size is selected as in the case of the left side.

  On the other hand, if it is detected in the detection process S4 that no original is set on the right edge portion 5b, the process ends because there is no original to be read.

  When the detection of the position where the original is set and the detection of the original size are completed, the scanner 2 is activated, and the original is scanned and read (S6).

  The image read as described above is temporarily stored as bitmap data in the storage means 9.

  At this time, the user sets the book manuscript corresponding to each page depending on whether the page is to be read or whether the left and right sides of the spread state are to be read.

  For example, when reading both the left and right sides in a spread state, the right side is read with respect to the left side that has already been read, but the book original set at the edge of the left end of the platen is Slide and set to the edge of the end.

  In this way, the book document is set on the edge of one end of the platen, and one side of the book document in a spread state is read. Thereafter, the other side can be read simply by sliding the book original to the edge part of the other end, and thus the readability of the book original in the spread state is improved.

  By the way, when the book setting mode is set by the mode setting means 8, the double-sided spread image of the book document is printed on one sheet of paper, and when the reading on both the left and right sides is completed, the combining means 11 is activated and the bitmap data on the storage means 9 is combined, and then output by the output means 10 as an image of a book document in a spread state on one sheet.

  When a book document is set on the edge portion on the end point side in the sub-scanning forward direction of the scanner, the scanner is configured to scan and read in the reverse direction with respect to the sub-scanning forward direction. Alternatively, the mirror image processing may be performed and then output.

  The configuration described in the above embodiment is merely a specific example and does not limit the technical scope of the present invention. Any configuration can be employed within the scope of the effects of the present application.

  Forming edge portions for setting the stitches of the book document at both end positions of the platen is useful because the operability of reading the book document in a spread state is improved.

It is the schematic which shows the structure of the image processing apparatus in embodiment of this invention. It is a functional block diagram of the image processing apparatus in an embodiment of the present invention. FIG. 3 is a longitudinal sectional view showing a state in which a book document is set in the image processing apparatus according to the embodiment of the present invention.
