ABSTRACT:
An optical beam scanning apparatus wherein a beam shaping device for forming a flat light beam which has a large width in the scanning direction and which is substantially parallel with the direction of the optical axis is disposed between a light source and rotary polygonal mirror, and a cylindrical lens bent to have both ends in the longitudinal direction thereof approaching to the scanned plane is disposed between a condensing lens for condensing the light beam reflected by the rotary polygonal mirror and a scanned plane in the vicinity of the latter. The rotary polygonal mirror and the scanned plane are arranged to have a conjugate relation with each other from geometrical optics. The light beam is converged so as to generate the beam waist near the scanned plane.
