In an image reading apparatus for reading a transparent original, the object of the present invention is to obtain a high-quality read image from which dust or scratch is removed. In order to achieve this object, in the image reading apparatus for reading the transparent original, a transparent original illumination unit has the first and second surfaces on the same side. On the first surface, at least one light source for emitting light in at least a visible range is arranged. On the second surface, at least one light source including a plurality of infrared light sources arrayed in series to emit light in an infrared range is arranged. The first and second surfaces are arranged at positions different from an effective light-emitting region, and includes a light guide plate and reflecting sheet for substantially uniformly emitting incident light from the same side portion to an entire surface. |
