ABSTRACT:
A scanning apparatus using a rotary polygon mirror comprises a rotary polygon mirror, a motor for driving the rotary polygon mirror, an optical lens system positioned in front of the rotary polygon mirror for projecting a laser beam onto the rotary polygon mirror and outputting the laser beam reflected thereby toward a photosensitive drum, and a housing for enclosing the rotary polygon mirror in a closed space formed therein and accommodating the optical lens system.
