Abstract:
1. An image reading device comprising: an illumination portion that irradiates light onto an original, including: a luminescence portion composed of at least one of: a plurality of dot-shaped luminescence members that is disposed at predetermined intervals in a main scanning direction; and an elongated luminescence member that is formed to extend in the main scanning direction; a light guiding body that is disposed between the luminescence portion and the original, including: a light incidence portion disposed on a side of the luminescence portion, and a light emission portion including a first emission surface disposed on a side to the original and a second emission surface formed on a different plane from a plane including the first emission surface; at least one mirror that forms a light path by reflecting a luminous flux from the original; an imaging lens that forms an image from the luminous flux reflected by the at least one mirror; and a reading portion that is disposed in an imaging position of the imaging lens, and reads an image of the original based on image formation by the imaging lens wherein the light guiding body comprises: a first light guiding body that includes the first emission surface; and a second light guiding body that includes the second emission surface.
