Abstract: An image reader apparatus for lighting a manuscript surface of a manuscriptin a line state, and for image-forming a reflection light from a reading part of the manuscript surface lighted in the line state, to an image sensor, by an image forming lens which forms a part of a scaled down optical system so that an image of the manuscript is read, includes an irradiation opening part and an optical element. The irradiation opening part is for irradiating a lighting light to an outside part, which is formed at the light source. The optical element for attenuating a light amount so as to be permeated, which is provided between the irradiation opening part and the manuscript stand.
