Abstract
An imaging optical mechanism includes a first concave mirror and a second concave mirror at a position shifted from the first concave mirror in a sub-scanning direction. A plurality of aperture members in which slits are formed is disposed between the first concave mirror and the second concave mirror. The first concave mirror reflects light incident from an original document so as not to be imaged at a position between the first concave mirror and the second concave mirror in the sub-scanning direction, and reflects light incident from the original document so as to be imaged at the position between the first concave mirror and the second concave mirror in a main scanning direction. The second concave mirror reflects light which is reflected by the first concave mirror and incident thereto, so as to be imaged at a position of a sensor.
