Abstract
An image reading apparatus is disclosed. The image reading apparatus provides plural sensors and a correction unit that corrects displacement of image data caused by intervals among the plural sensors and includes a first draft reading mode whose scanning direction by the sensors is the same as at the time of shading correction and a second draft reading mode whose scanning direction by the sensors is different from at the time of shading correction. The correction unit includes plural paths in which a different number of delay units are disposed in each path and changing over units that change over a connection between the sensors and the paths. The changing over units are changed over between at the time of reading image data and the shading correction in the first draft reading mode and at the time of reading image data in the second draft reading mode.
