Abstract

The image reading apparatus includes a light transmissive member (103), a first light source (115) causing a first light to enter the light transmissive member from a first side face of side faces thereof, a second light source (104) illuminating a document laid on an upper face of the light transmissive member with a second light, an image sensor (107) photoelectrically converting an optical image, and an imaging optical system (106) forming on image sensor the object image with light exiting from the light transmissive member. The first light source is disposed such that the first light emitted therefrom and entering the light transmissive member from the first side face satisfies a total reflection condition at the upper and lower faces of the light transmissive member.
