Abstract
A scanning apparatus for obtaining plural scanning beams, wherein plural stationary light beams are incident upon a deflecting reflection surface in different directions, but they are superposed with each other on the reflection surface. Plural scanning beams are provided from the deflecting reflection surface. Since the plural beams are superposed on the reflection surface, the center of deflection is the same for all of the light beams, so that the scanning beams are easily processed by a single optical system.
