Light scanning apparatus and two-dimensional image forming apparatus

摘要

A one-dimensional image is formed by reflecting the light from a one-dimensional display device having a plurality of light emitting sections or light emitting sections disposed in one direction by a projection optical system three times or more. Then, a two-dimensional image is obtained by optically scanning the one-dimensional image by a light deflection means in a surface including a direction perpendicular to the disposing direction of the light emitting sections or the light emitting sections in the one-dimensional display device. A magnification projecting system is provided to project the two-dimensional image by magnifying it as it is as an intermediate image. A requirement for high resolution can be coped with by employing the one-dimensional display device as well as a small and less expensive light scanning apparatus and two-dimensional image forming apparatus can be realized thereby.
