Filed: 2008-09-04
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image reader which can obtain accurate shading correction data at an original reading line position and avoid influence on image data due to paper powder.  <P>SOLUTION: When an original front end Q gradually rises along an incline, an original P is pulled up to an exposure reflection surface 52 side of an original guide 51. Since the exposure reflection surface 52 is a plane, it comes into contact with paper only at two points of an upstream corner part 54 and a down stream corner part 55 of the exposure reflection surface 52, and it never comes into contact with a plane portion corresponding to a reading line. In this process, an original surface side of the exposure reflection surface 52 is curved in a carrying direction over a major scan direction, and a center point R of the curve is set near on a reading line; thus putting a top R of the curve on the read line. According to the curved shape, the original P which gradually rises along an incline of a scoop-up guide 53 is pulled up to a white surface side of the reading guide 52, and comes into contact with a white surface of the reading guide 52 curved in a projection shape.  <P>COPYRIGHT: (C)2010,JPO&INPIT
