Abstract
A light scanning device includes a movable section having a light reflecting section adapted to reflect light, oscillating around an oscillation axis, and having a variable magnitude of a maximum deflection angle of the oscillating, and a detection section adapted to detect the maximum deflection angle of the movable section, and the detection section includes a light source adapted to emit light to the light reflecting section, a light receiving section adapted to receive reflected light, which is the light emitted from the light source and then reflected by the light reflecting section, and a displacement driving section adapted to change a position of the light source in accordance with the maximum deflection angle of the movable section.
