  • Patent number: 8654172
    Abstract: A plurality of light sources, a light deflector, and a single scan lens. The light deflector deflects a plurality of light beams emitted from the light sources by a same face for scanning a plurality of to-be-scanned portions simultaneously. The single scan lens receives the light beams from the light deflector and focuses the light beams onto each of the plurality of to-be-scanned portions to scan the to-be-scanned portions simultaneously. The single scan lens is used in common for the light beams, and has one incidence plane and a plurality of exit planes in a sub-scanning direction separately prepared in the sub-scanning direction for each of the to-be-scanned portions. The incidence plane has a refractive power of the lens in the sub-scanning direction decreasing toward peripheral portions in the main scanning direction. The exit planes have positive refractive power in the main and sub-scanning directions.

  • Patent number: 8363083
    Abstract: In a light source device, a light-emitting element and a coupling lens configured to condense a beam of light emitted from the light-emitting element are held by a holding member. The holding member has an adherend that is opposite to a surface of the coupling lens facing to the light-emitting element in a direction of an optical axis of the coupling lens. Part of the surface of the coupling lens facing to the light-emitting element is bonded to the adherend of the holding member. In the optical scanner which includes this light source device, a beam of light emitted from the light source device is deflected by a deflector so that a target surface is scanned with the beam of light, and the deflected beam of light is caused by an image forming optical system to focus on the target surface, to form an image thereon.
