Abstract:
An optical scanning device according to an embodiment includes a light source, a MEMS mirror, a MEMS-mirror driving unit, a control unit, and a sensor. The light source radiates a plurality of laser beams that scan a photoconductive drum. The MEMS mirror includes a reflection surface that reflects the plurality of laser beams radiated from the light source. The MEMS-mirror driving unit reciprocatingly moves the MEMS mirror. The sensor supplies a horizontal synchronization signal to the control unit by detecting the laser beam reflected on the reflection surface when the MEMS mirror reaches a predetermined position. After detecting the horizontal synchronization signal supplied from the sensor, the control unit performs the auto power control of the light amount of at least one laser beam among the plurality of laser beams.

Claim (Index 1):
An optical scanning device comprising:\n a light source comprises a plurality of emitting units and one light receiving unit that receives a light beam from the plurality of emitting units and radiates a plurality of laser beams configured to scan a photoconductive drum; a MEMS mirror, including a reflection surface that reflects the plurality of laser beams radiated from the light source, moves reciprocatingly by a driving unit; a sensor configured to supply a horizontal synchronization signal by detecting a laser beam reflected on the reflection surface when the MEMS mirror reaches a predetermined position where the plurality of laser beams does not scan the photoconductive drum; and a controller\n that performs auto power control for controlling respective light amounts of the plurality of laser beams radiated from the light source to predetermined values, \n that controls so as to emit one of the plurality of emitting units, \n that, based on the horizontal synchronization signal supplied from the sensor, performs a first auto power control of the light amount of at least one laser beam among the plurality of laser beams, and \n that does not execute at least a second auto power control for the light emitting unit of the plurality of light emitting units while the one of the plurality of light emitting unit emit.
