Abstract: An optical scanning device includes a housing, the interior of which is partitioned into a first compartment and a second compartment by a base; a light source arranged in the first compartment and adapted to emit a beam; a first optical component arranged on an optical path of the beam in the first compartment; a second optical component arranged on the optical path of the beam in the second compartment; an aperture formed in the base to allow the beam to pass from the first compartment to the second compartment or from the second compartment to the first compartment; and a reinforcing member for reinforcing the rigidity of the base near the aperture.

Abstract: An optical scanning apparatus includes a housing, light source, deflector, imaging lens, reflective mirrors, a synchronization detector and synchronization detection mirror. The housing has a plate to partition the housing. The deflector deflects a light beam emitted from the light source. The imaging lens converts the deflected light beam into a constant speed scanning light beam. The reflective mirrors reflect the constant speed scanning light beam to a photoreceptor. The synchronization detector detects timing for starting scanning of the photoreceptor. The synchronization detection mirror reflects the light beam to the synchronization detector. At least one of the reflective mirrors is disposed midway in a synchronization detection light path extending from the deflector to the synchronization detection mirror. The light beam reflected by the synchronization detection mirror is reflected again by at least one of the reflective mirrors, such that the light beam is guided to the synchronization detector.
