Claims

[Scope of utility model registration request]

In an optical scanning mechanism of a copying machine that scans a fixed document table, a fixed rack fixed to the copying machine body and a pinion gear that engages with the fixed rack are rotatably supported and fixed to a pinion support member. a half-speed mirror unit fixed to a movable rack that meshes with the pinion gear, and either the half-speed mirror unit or the full-speed mirror unit that moves at twice the speed of the half-speed mirror unit. An optical scanning mechanism characterized by reciprocating drive.
