備えたことを特徴とする画像読取装置。[Claims for Utility Model Registration] A fixed scanning object on which information is recorded, a light source that irradiates the scanning object with light, and a reduction in the reflected light of the light irradiated from the light source to the scanning object. A self-scanning scanner unit comprising a lens for forming an image, and a CCD image sensor for electronically scanning the image formed by the lens to extract an electrical signal; The first one changes the optical path of the reflected light from the object to be scanned.
and a substantially rectangular shape so that the optical path length of the reflected light whose optical path has been changed by the first optical path changing means until it is received by the CCD image sensor is always constant during scanning by the self-scanning scanner unit. 1. An image reading device comprising: a second optical path changing means consisting of four mirrors arranged in a shape.
