Abstract:
1. An image reading apparatus, comprising: a plurality of light sources, arranged in a straight line, configured to output light to a document, each of said light sources having an exit side surface to emit output light; a light leading member having an incidence surface facing the exit side surface to receive the output light from the exit side surface of the light sources, and configured to lead received light so as to irradiate along a main scanning direction toward the document; a substrate including the light sources attached onto a surface of the substrate in the straight line, said surface of the substrate crossing the exit side surface of the light sources, said substrate and the light leading member being positioned parallel to a direction of light received by the light leading member, said substrate directly contacting the light leading member so that a part of a surface of the substrate on a light emitting direction side relative to the light sources and a periphery of the light leading member crossing the incidence surface thereof face each other; a photoelectric conversion element configured to receive reflection light from the document; and a holder configured to hold the light leading member.
