ABSTRACT:
A polygon mirror apparatus preventing a polygon mirror from separating from a rotor, having a rotor housing integrally formed with a polygon mirror is provided. The polygon mirror apparatus includes a base, a bearing coupled with the base, and a rotating shaft installed at the bearing to be rotatable. A polygon mirror is coupled with the rotating shaft to deflect and scan incident light. A driving source rotates a polygon mirror using electromagnetic power. A stator is positioned at the bearing, and a rotor installed around the stator so as to be rotatable, and is partially inserted into the polygon mirror by insert molding.
