Abstract
PURPOSE:To obtain an optical system for correcting the fall of a rotary reflector where the position adjustment is easy, by arranging a roof-shaped correcting mirror whose vertical angle is not 90 deg. so that the axial direction of the bent part of this mirror is orthogonal to the axial direction of the rotary reflector and reflecting the light on the rotary reflector, the correcting mirror, and the rotary reflector in order and transmitting this reflected light to an ftheta lens. CONSTITUTION:A roof-shaped correcting mirror 4B whose vertical angle is obtuse is arranged for a rotary reflector 3B so that the axial direction of the bend of the correcting mirror 4B is orthogonal to the axial direction of the rotary reflector 3B. The light from a light source 5B is reflected by the rotary reflector 3B and is reflected twice by the correcting mirror 4B and is reflected again by the rotary reflector 3B and is transmitted to an ftheta lens. Since the comparatively large correcting mirror 4B where the position adjustment is easy is used, an optical system for correcting the fall of the rotary reflector where the position adjustment is easy is obtained.
