Abstract
A document reader includes an image sensor. The image sensor is movable in a secondary scanning direction and rotatable about a rotational axis extending in a primary scanning direction, and obtains image information from a region facing a light-receiving surface. Rotation of the image sensor is controlled based on distance information about a distance between a document surface and a platen in such a manner as to make an image distance fall within a depth-of-field range of the image sensor.
