PROBLEM TO BE SOLVED: To realize a rotary polygon mirror easy to be assembled to a drive part. SOLUTION: A pedestal 4 integrated with a rotor magnet 5 is provided with six pieces of recesses 4b on a reference surface 4a. Adhesive 6 is filled up in three pieces among them, and the rotary polygon mirror 1 is loaded, and the adhesive 6 is filled, and the rotary polygon mirror 1 is integrated with the pedestal 4. Since the assembly of the rotary polygon mirror 1 is simplified, and an asymmetric parts such as an E ring, etc., isn't required, the rotary polygon mirror 1 is rotated stably at high speed. |
