PROBLEM TO BE SOLVED: To provide a polygon mirror scanner motor that a metal base plate is electrically connected to the GND pattern of a motor controller and which has simple structure, a high quality at low cost. SOLUTION: In a polygon mirror scanner motor having a metal base plate, the plate 1 has the insertion hole 14 of a sleeve 2b made of a conductive material so that the noise on the plate 1 does not affect the influence of the accuracy of the number of revolutions of a polygon mirror, a sleeve 2b is engaged fixedly with the pattern 15 of the controller disposed in the radial direction of the hole 14. Thus, the motor that the plate 1 is electrically connected to the pattern 15 of the controller to make it possible to simplify the structure of the plate 1 and which realizes the easy operation, high quality and low-cost is obtained. |
