Abstract:
An optical scanning apparatus comprising a light source; a light deflector for deflecting and scanning a luminous flux from said light source; a first optical system, disposed between said light source and said light deflector, for converging said luminous flux in a direction orthogonal to a light-scanning direction of said light deflector and linearly focusing said luminous flux near a light-deflecting surface of said light deflector; and a second optical system for causing said linear luminous flux deflected by said light-deflecting surface to form a point-like image on a surface to be scanned; whereby a light spot formed as the point-like image on said surface to be scanned is scanned according to an operation of said light deflector;wherein at least one lens within said second optical system transmits therethrough the luminous flux directed from said light source to said light deflector, such that said luminous flux intersects an optical axis of said second optical system within said lens.
