<p>A color image reading apparatus comprises a plurality of line sensors (8,9,10) which are a plurality of one-dimensional sensor arrays disposed on a single substrate (4), a projection optical system (2) for projecting an image of a subject on the sensors, a blazed diffraction grating (3) disposed in an optical path between the projection optical system and the sensors to separate light from the subject (1) into a plurality of color lights, and a wavelength selection device (31) disposed in an optical path between the subject and the sensors to permit only a beam of light within a specific wavelength range to pass therethrough. <IMAGE></p> |
