BEARING ASSEMBLY AND SCANNING MOTOR

摘要

PURPOSE: A shaft support assembly and scanning motor are provided to reduce vibration and noise generated during fast rotation. CONSTITUTION: A sleeve(130) forms a hollow hole. A shaft(140) can rotate in the hollow hole. A thrust plate(150) contacts the end of the shaft to reduce fraction when the shaft rotates. The sleeve and the thrust plate are arranged in a holder(160). The holder point-contacts the side which contacts the thrust plate.
