Image reading apparatus, shading correction method therefor, and program for implementing the method
Patent number: 8570611Abstract: An image reading apparatus including a shading correction mechanism that can be formed by fewer component parts than conventional ones, and is increased in the degree of freedom of design, thereby enabling reduction of the size and weight thereof. A contact glass guides an original to an image reading position. A glass holding member holds the glass. A line image sensor reads an image on the original conveyed to the image reading location, through the contact glass. A reference member is disposed at a location different from the image reading location on the contact glass. A moving mechanism relatively moves the line image sensor and the reference member so that the line image sensor can alternatively read the original conveyed to the image reading location and the reference member. A drive section externally drives the moving mechanism to move the line image sensor and/or the reference member.Type: GrantFiled: November 15, 2012Date of Patent: October 29, 2013Assignee: Canon Denshi Kabushiki KaishaInventors: Jun Tanaka, Takashi Machida, Shinobu Kato, Keiji Tsutaoka, Taketo Ochiai, Masahiro Shirai, Shigeru Ikezaki, Hirotaka Watanabe -

Patent number: 8371428Abstract: An original processing apparatus capable of enhancing original processing ability even in the case of continuously processing a plurality of originals. In a first processing unit of the original processing apparatus, MICR characters on an original conveyed along a conveying path are read and an image of a front side of the original is read. The original is then conveyed to a position short of a second processing unit, and the next original is fed to the conveying path. When control information including print information is created based on a result of the processing by the first processing unit, the original positioned short of the second processing unit is conveyed to the second processing unit where print information is printed on the original and an image of a back side of the original is read.Type: GrantFiled: December 23, 2009Date of Patent: February 12, 2013Assignee: Canon Denshi Kabushiki KaishaInventors: Masato Odagiri, Satoru Kitabayashi, Shigeru Ikezaki, Mitsuru Konishi
