ABSTRACT:
A light scanning optical system of an image output scanner comprises an irradiating optical system, an electro-mechanical light modulator comprising a number of elements on which a light beam is incident from a light source through the irradiating optical system and which are capable of deflecting the light beam in at least two directions in accordance with an input signal, the elements being arranged in the main scan direction, the elements making image information by the change-over of the direction of deflection, and a projection optical system for projecting only the signal light of the image information, the image of the light source being set so as to be formed on the entrance pupil of the projection optical system at a magnification in the vicinity of one-to-one magnification.
