Abstract
An optical scanner assembly has optical members divided and arranged on the front and reverse surfaces of a base, thereby reducing the size of the base such that the base can be formed of metal without an increase in cost in order to allow the optical and scanning characteristics to remain stable with time. In one embodiment, a laser light source, a collimator lens, and a cylindrical lens are on the reverse surface of a chassis with reference to mounting references prepared on the reverse surface, while a reflective return mirror, a polygonal mirror, and f&thgr; lenses are mounted on the front surface with reference to mounting references prepared on the front surface.
