Abstract
The invention provides an improved color image reader in which the document having a color original image is irradiated by a light source moving relatively on such document and the reflected light is introduced into a single unit including a lens and a color separator so that the color original image is separated into plural color component images. The plural color component images are respectively read and photo-electrically converted into plural signals by CCD's. In such arrangement, the light source is positioned at the upper side of the optical axis of the lens and the CCD's are disposed at the lower side of the axis. The color separator can form the plural color component images on the same plane.
