摘要
A color image reading apparatus includes a light-receiving unit in which a plurality of line sensors are disposed at equal intervals on a same substrate, an imaging optical system for imaging an object on the light-receiving unit, a blazed diffraction grating, disposed in an optical path between the imaging optical system and the light-receiving unit, for color-separating light from the object into a plurality of color light beams, and a dichroic mirror disposed in an optical path between the blazed diffraction grating and the light-receiving unit, and having at least two reflecting surfaces.
