JP2006197273A - Double-side reading type book compatible scanner - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a scanner compatible with a book that can read an image by 2-spread pages at once and also completely read a binding margin through double-side reading when reading images of a book or a magazine and can attain double-side reading of a slip printed with on both sides at once. <P>SOLUTION: The scanner compatible with a book is configured to include only one optical system read means such as a CCD wherein an angle of a mirror for reflecting a light reflected from an original side is made variable so that the double sides can sequentially be scanned. The scanner is configured to include a special purpose optical system read means for reading a binding margin at a head part of the scanner. In the case of the scanner provided with two optical system read means such as CCDs, the scanner itself has two-left/right-split structured parts and can be configured to face read sides ordinarily reading 2-spread pages of a book with each other by turning the head of the scanner as a fulcrum. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a book-compatible scanner and realizes a double-sided reading function.

  In a normal flatbed scanner, when reading a bound document such as a book or a magazine, the document is strongly pressed against a glass surface for placing a document on the flatbed so that the binding margin can be read as much as possible.

  However, with a thick book or the like, it is difficult to bring the binding portion into close contact with the glass surface, and there is a problem that the image reading is inevitably lost.

  In order to solve such a problem, a book-compatible scanner has been devised (see Patent Document 1).

  Since the conventional book-compatible scanner as shown in FIG. 4 is single-sided reading, in order to read an image of a book, the image must be read while placing the original on the reading surface page by page. It was difficult to read two pages at a time, and it was difficult to read single-sided sheets that were printed on both sides, one by one.

  Moreover, although the binding margin is not as large as the flat bed, there is a problem that it cannot be completely read.

Japanese Patent Application No. 2004-329131

  As described above, the conventional techniques have the following problems.

  When scanning an image of an original that has been bound in the center, such as a book or magazine, with a flatbed scanner, the book or magazine that is the original is strongly pressed against the glass surface of the platen, and the binding margin is also in close contact with the glass surface. However, there was a problem that the binding margin could not be read with a thick book.

  In order to solve this, a book-ready scanner has been devised, but because it is single-sided reading, the only way to read the image of the book is to place two pages spread on the reading side one side at a time, When a single sheet is printed on both sides, it has to be read one side at a time and is difficult to use. In addition, although the binding margin is not as large as the flat bed, there is a problem that it cannot be read completely.

  SUMMARY OF THE INVENTION An object of the present invention is to enable image reading at a time by double-sided reading for two pages of spread when reading an image of a book or a magazine with a book-compatible scanner. Further, it is also possible to completely read the binding margin portion and to allow double-sided reading of single-sided printed sheets at once.

  In order to solve the above problems, the present invention takes the following means.

  This is a book-compatible scanner, and includes only one optical reading means such as a CCD, and the mirror angle that reflects the reflected light from the document surface can be made variable so that both sides can be scanned sequentially.

  This is a book-ready scanner that has two optical reading means such as CCDs and is configured to spread the reflected light from the document surface so that it is incident on the optical reading means at the same time for two pages. You may be able to do that.

  A reading means of a dedicated optical system that reads the binding margin is provided on the top of the book-compatible scanner.

  In the case of a book-ready scanner that has two optical reading means such as a CCD, the surface that reads two pages of a book is usually divided into a left and right structure, and the top of the scanner is It can be configured to rotate as a fulcrum and face the reading surface.

  According to the present invention, the following effects can be expected.

  A book-ready scanner can scan two pages of a book at a time, simultaneously scanning the binding margins completely, and printing on both sides by facing the reading side. It is also possible to simultaneously read images on both sides of a single sheet.

  The present invention takes the following embodiment.

  In order to be able to read both left and right originals with a book-ready vertical scanner, it is equipped with a single optical reading means such as a CCD, which reflects the reflected light of the original and guides the reflected light to the CCD. By making the angle of the mirror variable, the image on both sides can be scanned sequentially.

  As a result, two pages of the book can be sequentially read.

  This is a book-ready vertical scanner that has two optical reading means such as CCDs for both the left and right sides, so that the reflected light of two spread pages is incident on the reading means simultaneously on each page. Good.

  As a result, two pages of the book can be read simultaneously at the same time.

  A reading means of a dedicated optical system for reading the binding margin portion is provided on the top of the book-compatible scanner.

  As a result, it is possible to completely read the image of the binding portion of the two-page spread of the book.

  This is a book-ready vertical scanner that has two reading systems for optical systems such as a CCD for both the left and right sides. The scanner can be configured to rotate with the top of the scanner as a fulcrum to face the reading surface.

  As a result, by sandwiching the single-sided printed sheet between the reading surfaces facing each other, it becomes possible to perform image reading on both sides simultaneously.

  A typical embodiment according to the present invention will be described with reference to the drawings. In the following, the same portions are denoted by the same reference numerals, and detailed description may be omitted.

  FIG. 1 shows a mechanism for performing double-sided printing. In FIG. 1A, by rotating the angle of the reflecting mirror 1 by 90 degrees, the reflected light from the lamp left 2 and the lamp right 3 is guided to the CCD 4 to sequentially read the A-side and B-side documents. It is configured to be able to.

  FIG. 1B shows that the reflected light from the lamp left 2 and lamp right 3 is simultaneously guided to the CCD 4 by the triangular reflecting mirror 1 so that the A-side and B-side documents can be read simultaneously. It is composed.

  By configuring the optical unit in this way, double-sided reading can be performed with a book-compatible scanner.

  The scanner may be provided with a dedicated optical reading means for reading the binding margin as shown in FIG. This is a combination of the wide-angle lens 5 and the CCD 4, and the image is likely to be distorted. Therefore, by correcting and joining the scanned images on both the left and right sides, it is possible to read a double-sided spread image with no gaps in the binding margin. Can be done.

  Further, as shown in FIG. 3 (a), a two-part structure body having one optical system unit may be configured to be rotated so that the left and right image reading surfaces face each other. Good.

  As a result, as shown in FIG. 3B, it is possible to read a single sheet on both sides by sandwiching the single sheet between the image reading surfaces facing each other.

It is explanatory drawing of a double-sided reading mechanism. It is explanatory drawing of the reading mechanism of a binding margin part. It is explanatory drawing of the double-sided reading mechanism of a single sheet. This is a conventional book-ready scanner.
