Abstract
The present invention is aimed at providing an image reading device that suppresses generation of a so-called edge shadow while suppressing uneven intensity of light emitted onto an original. A color copy machineincludes an illumination portionthat irradiates an original G with light. The illumination portionincludes a plurality of LEDsdisposed at predetermined intervals in a main scanning direction, an elliptical diffuser platethat is disposed between the plurality of LEDsand the original G and causes the light emitted by the plurality of LEDsto diffuse, and a second reflection mirrorB that reflects light, which is a portion of the light diffused by the elliptical diffuser plateand not directly irradiated onto the original G, so as to irradiate the light onto the original G.
