ABSTRACT:
A polygonal mirror apparatus with an improved installation structure of a polygonal mirror, which is made using a plastic material, with respect to a rotor frame. The polygonal mirror apparatus includes a base, and a bearing coupled to the base and having a first bore. A rotating shaft is rotatably installed in the first bore. A rotor frame rotates together with the rotating shaft. A polygonal mirror is secured to the rotating shaft and coupled to the rotor frame through insert molding. The polygonal mirror deflects and scans incident light. A driving source formed at the bearing and the rotor frame rotates the polygonal mirror using electromagnetic power.
