る画像読取装置。 While the optical system mechanically scans the document reading area in the sub-scanning direction, the image sensor electrically scans the one-dimensional image in the main scanning direction on the document reading area to create a two-dimensional image. In the image reading device configured to read the document, a shading pattern extending in the sub-scanning direction is provided in an area adjacent to the document reading area, and this shading pattern is read by the image sensor simultaneously with the document reading, and the shading pattern read by the image sensor is read by the image sensor. An image reading device characterized in that a shift pulse is output to the image sensor according to a pattern.
