Abstract
In an image reading apparatus having a first original reading device for reading one side of an original guided and fed by a guide, and a second original reading device disposed downstream of the first original reading device for reading the other side of the original, the guide is bent between the first original reading device and the second original reading device so as to shield the respective reading devices. The bending of the guide is done by bending an original feeding path so that direct rays and diffraction rays from each of two light sources may not enter respective photoelectric transfer elements associated with other light source, to thereby shield the photoelectric transfer elements from light of a light source not associated therewith.
