Abstract
A laser beam is projected from a laser oscillator 1 and converged by a condenser lens 2. The laser beam converged by the condenser lens 2 is reflected in any arbitrary direction by a scanning mirror 4 which is rotated by scanning means 3. The laser beam is linearly moved. The laser beam is reflected by a curved surface reflecting mirror 5 which is formed in a spherical surface in the primary scanning direction of the laser beam and an ellipsoid in the secondary scanning direction so that the scanned surface is scanned at a substantially predetermined speed.
