摘要： A common photodetecting unit detects a plurality of beams scanned by a plurality of polyhedral reflection mirrors provided in a multiple stages with a common rotation axis, and generates a synchronization detection signal based on detected beams. The reflection mirrors make a predetermined angle θ1 in a direction of rotation of the reflection mirrors. When time between two consecutive synchronization detection signals on a time line generated by the common photodetecting unit is ti, where i is a positive integer equal to or smaller than number of split beams, at least one of ti is different from others.

摘要： An optical scanning apparatus includes a light source, a light source driving unit that turns on the light source according to image information, a deflector that deflects and scans a light beam emitted from the light source according to sinusoidal vibration, and a scanning/imaging optical system that guides the light beam from the deflector to a scanned surface. The scanning/imaging optical system satisfies two conditions, i.e., (1) provided that the deflector moves in such a manner that an angular velocity is constant, linearity is made larger at a most peripheral image height than at a central image height within a range of an effective writing width, and (2) when a deflection angle of the deflector has a sinusoidal characteristic, the linearity is made smaller at the most peripheral image height than at the central image height within the range of the effective writing width.

摘要： An optical scanning device includes a deflecting unit, a first sensor, and a modulating system. The deflecting unit deflects a plurality of beams in a main scanning direction to a writing area of a surface to be scanned for scanning the writing area. The first sensor detects a beam to be incident on a point on a first side of the writing area, and outputs a signal in response to detected beam. The modulating system modulates the beams in synchronization with the signal output from the first sensor.
