Abstract:
1. An image reading apparatus comprising: an illumination apparatus including a light source that generates light for reading an image, and a light guide body extending in a predetermined direction, onto which the light from the light source is incident, and which includes a pair of first faces, a second face and a third face, the pair of first faces reflecting portions of the light to an image reading region from directions different from one another, the portions of light reflected from the first faces being transmitted through the second face and onto the image reading region and being reflected from the image reading region to be incident on the second face, the portions of light incident on the second face passing between the pair of first faces and being transmitted through the third face; an image sensor that receives the portions of light transmitted through the third face of the light guide body and performs a photoelectric conversion on the portions of light; an optical system that forms an image on the image sensor from the portions of light transmitted through the third face; a case that accommodates the illumination apparatus, the image sensor, and the optical system and moves parallel to a plane of the image reading region, an inside of the case being optically sealed, the illumination apparatus penetrating through the case; and a cleaner that comes into contact with the second face of the light guide body as the case moves parallel to the plane of the image reading region.
