    摘要: An apparatus provided with a first reflector for reflecting a light beam deflected by a deflector in a light beam scanning apparatus and a second reflector for directing the light beam from the first reflector toward an image forming point after contacting again the first reflector. The light beam is reciprocated between the first and second reflectors thereby forming a light path of two times the space that they are disposed. A deflector is disposed on a side of the light path extending from the first reflector to the light beam image forming point together with a light beam emitting source which irradiate the light beam on the same level of the light path and make the light path length at both ends of the light beam scanning range equal to each other by arranging an angle between the first and second reflectors.
