Abstract:
1. An image reading device comprising: A luminescence portion that emits light for irradiating an original; A light guiding body that is disposed between the luminescence portion and the original, and has a first light incidence portion disposed on a side to the luminescence portion and a first light emission portion disposed on a side to the original; a first reflection surface that is a part of an outer surface of the light guiding body connecting the first light incidence portion and the first light emission portion; a light guiding space constitutive member having a second reflection surface that is disposed at a position facing the first reflection surface and that faces the first reflection surface; a light guiding space formed between the first reflection surface and the second reflection surface, having a second light incidence portion disposed on a side to the luminescence portion and a second light emission portion disposed on a side to the original; 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.
