ABSTRACT:
A drive motor for rotating a multi-faceted mirror to change the path of a laser beam in a laser printer or a laser scanner. The drive motor for rotating the multi-faceted mirror has a stator, a rotor, and a bearing disposed between the stator and the rotor for supporting the rotation of the rotor, and the bearing is a hemispherical fluid bearing. Therefore, shaking and noise can be efficiently reduced when a laser printer or a laser scanner prints or scans at a high speed.
