ABSTRACT:
A plural-beam scanning apparatus comprises a light source unit having a plurality of light-emitting portions, a deflector for deflecting the light beams from the light-emitting portions, a prism for refracting the light beams from the light-emitting portions so that the central light rays of the light beams emitted from the light-emitting portions of the light source unit as if they originated from or pass through substantially the same point, and an imaging system for rendering that same point and a point near the reflecting surface of the deflector optically conjugate.
