摘要： A light deflector device includes a light deflector having an oscillation system, a driving unit for driving the oscillation system and a drive controlling unit for supplying a drive signal. The oscillation system simultaneously generates a first oscillating motion of a first frequency and a second oscillating motion of a second frequency. The drive controlling unit supplies a drive signal formed by synthetically combining a first signal having the first frequency and a second signal having the second frequency to the driving unit and, at the same time, another drive signal for changing at least the amplitude of the first oscillating motion, the amplitude of second oscillating motion or the relative phase difference of the first oscillating motion and the second oscillating motion to the driving unit in order to correct an offset of scanning light deflected by the light deflector.
