Light scanning device with microlenses having a same power density distribution as a power density distribution of a photosetting light beam

摘要

A light scanning device of the present invention comprises: a light source for emitting light; a liquid crystal shutter array comprising a plurality of liquid crystal shutters arranged in a first direction, the liquid crystal shutter array receiving image signals to selectively open the liquid crystal shutters in response to the image signals, to thereby selectively allow the light emitted from the light source to pass therethrough; a photosensitive member for receiving the light which has passed through the liquid crystal shutter array, said photosensitive member being conveyed in a second direction perpendicular to the first direction to thereby form a latent image thereon corresponding to the image signals; and focusing means provided on each of the liquid crystal shutters for focusing the light having passed through said liquid crystal shutter array onto the photosensitive member, the focusing means being formed of a photosetting material.
