Abstract
An optical scanning apparatus includes a light source, a substrate, a reflection member, a drive unit, and a controller. A scanning mirror and an attitude detector are integrated with substrate. An attitude detector outputs a first signal according to an attitude angle of substrate. A reflection member reflects a light beam reflected by scanning mirror. A drive unit can adjust an inclination of reflection member with respect to a main surface of substrate. A controller controls drive unit based on first signal. For this reason, an outgoing angle of light beam from optical scanning apparatus with respect to a horizontal surface can stably be maintained regardless of the inclination of optical scanning apparatus with respect to horizontal surface.
