PROBLEM TO BE SOLVED: To provide an image reading apparatus in which image quality deterioration caused by light interference of a neighboring optical path is eliminated and an optical axis is stabilized.SOLUTION: An image reading apparatus comprises: concave first lens mirrors disposed so as to face an irradiated body, and disposed in an array shape in a main scan direction for collimating scattered light of light reflected by the irradiated body and reflecting the collimated light as approximately parallel beam flux inclined in a sub scan direction; a first planar mirror for reflecting light from the first lens mirrors; apertures disposed in the array shape for passing light from the first planar mirror via openings which are disposed in the array shape for selectively passing light while shielding the light around the openings; concave second lens mirrors disposed in the array shape for making incident light from the apertures and reflecting the light as convergent light; and a light-receiving section which includes a light-receiving region to which light from the second lens mirrors is made incident to form an image correspondingly to light from the openings. |
