Abstract
An optical scanner has an oscillation-type optical scanning mechanism which includes a movable member which resonates at a predetermined resonance frequency, a drive signal generator which generates a drive signal for allowing the movable member to resonate at the resonance frequency, and an oscillation signal generator which generates an oscillation signal in response to a change of the radiation direction of the light beams. Here, the oscillation signal generator includes a dot clock generator which generates a dot clock which becomes the reference of time-series processing by setting a frequency of the oscillation signal as a reference frequency.
