Claims

[Scope of utility model registration request]

A polygon mirror that scans the light beam from the light source,
In an optical scanning device configured to rotationally drive the polygon mirror with a motor, the motor for rotationally driving the polygon mirror has an outer periphery covered by a case body and is configured to rotate within the case body, An optical scanning device characterized in that the polygon mirror is located at an end of the body in the direction of the motor rotation axis, and a through hole is provided that extends from the side of the motor of the case body to the vicinity of the polygon mirror.
