Abstract:
1. An image reading unit comprising: an image reading section including one-dimensionally aligned imaging elements to read an image of a document in a one-dimensional direction; a lens for converging light from the document to the image reading section; light sources each of which irradiates an image reading region read by the image reading section with light; and a rotation head that holds the image reading section, the lens, and the light sources in a manner that the image reading section, the lens, and the light sources are rotatable relative to the document about a rotation axis which is parallel to an alignment direction of the imaging elements, wherein the light sources are disposed at both sides of the lens in a direction of the rotation axis, and the image reading section and the light sources are disposed such that an irradiation plane indicating an irradiation range by the light sources overlaps with a scanning plane indicating a range of reading in the image reading by the image reading section.
