Abstract
Official abstract text for this publication.
An image reading unit includes an image reading section that reads an image of a document in a one-dimensional direction by one-dimensionally aligned imaging elements, a light source that irradiates an image reading region by the image reading section with light, and a rotation head that holds the image reading section and the light source in a manner that the image reading section and the light source are rotatable relative to the document about a rotation axis which is parallel to an alignment direction of the imaging elements.
First claim
Opening claim text (preview).
What is claimed is: 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 m…
