ABSTRACT:
An illumination device for a reading device which irradiates light over a predetermined illumination width including a reading area having a predetermined reading width extending in a main scanning direction of a document and reads the light reflected from the document using a reading element has a point light source, and a light-guiding member having an incident surface opposed to a light-emitting surface of the point light source and a light-emitting surface opposed to the reading area. An illumination area generated by the light has a high distribution range of a substantially constant illuminance, and the high distribution range coincides substantially with the reading area.
