Abstract
PURPOSE:To prevent the lubricant from becoming oil mist and sticking to the mirror, by forming a linear groove or a linear projection on the wall face of the rotary material such as the mirror rotation shaft to generate an air current. CONSTITUTION:Rotary polygonal mirror 7 is arranged in the mirror room partitioned by partition walls 8 and 9 in cylindrical case 1, and when a current is flowed to rotor 2 and stator 3 provided in case 1, this rotary polygonal mirror 7 is rotated in a high speed (10,000-20,000rpm) through rotation shaft 4 supported by bearings 5 and 6. The incident light beam is scanned through window glass 8 in a high speed by rotating polygonal mirror 7. Linear grooves or linear projections 11 and 12 are formed near partition walls of rotation shaft 4 to generate the air current flowed out from mirror room 13 during rotation driving, and clean air is led in through filter 15, and oil mist generated from the bearing and so on is ejected from air vents 16 and 17.
