Abstract
Disclosed herein is a scanner motor. The motor includes a base plate supporting the scanner motor, with a circuit board mounted on the base plate. A rotating shaft supports the scanner motor vertically in such a way that the scanner motor is rotatable. A bearing is rotatably fitted over the rotating shaft. A bearing holder holds the bearing. A stator is mounted to an outer circumference of the bearing holder to generate electricity. A rotor case is rotatably fitted over the rotating shaft so as to mount a polygon mirror. Three semicircular protrusions protrude from an upper portion of the rotor case at regular intervals to stably support the polygon minor. A concave part is formed between the protrusions to absorb external stress.
