An image reading device is provided that comprises: concave first lens mirrors (7) that are arranged in an array shape along a main scanning direction and that are adapted to collimate scattered light reflected by an irradiated object (1) and are adapted to reflect the scattered light as a substantially parallel bundle of rays that are angled in a sub-scanning direction; planar mirrors (8) that are adapted to reflect light from the first lens mirrors (7); apertures (9) that are arranged in an array shape and that allow light from the planar mirrors (8) to pass through by way of openings (10) that are arranged in an array shape and that are light-shielded therearound for selectively allowing light to pass through; concave second lens mirrors (11) that are arranged in an array shape into which light from the apertures (9) is incident and that are adapted to reflect the light from the apertures as converged light; and light receivers that have light receiving areas on which light from the second lens mirrors (11) is incident and that are adapted toform images that correspond to light from the openings. |
