Abstract
There is provided a polygon mirror scanner motor including: a rotor configured to rotate around a rotation axis; a fitting member configured to be fitted to an outer circumferential surface of the rotor; and a polygon mirror configured to be fitted to the outer circumferential surface of the rotor and bonded with the fitting member, wherein a diameter of the rotor at a part, to which the fitting member is fitted, is configured to be smaller than a diameter of the rotor at a part, to which the polygon mirror is fitted.

A polygon mirror scanner motor comprising:
- a rotor configured to rotate around a rotation axis;
- a fitting member configured to be fitted to an outer circumferential surface of the rotor;
- and
- a polygon mirror configured to be fitted to the outer circumferential surface of the rotor, the fitting member and the polygon mirror being bonded with each other by a bonding agent at respective surfaces perpendicular to the rotation axis,
- wherein a diameter of the rotor at a part, to which the fitting member is fitted, is configured to be smaller than a diameter of the rotor at a part, to which the polygon mirror is fitted, and
- wherein the respective surfaces perpendicular to the rotation axis overlap each other in the direction of the rotation axis.
A method for assembling a polygon mirror scanner motor, the method comprising:
- mounting a rotor on a stator,
- fitting a polygon mirror to an outer circumferential surface of a rotor through a fitting hole of the polygon mirror;
- fitting a fitting member to the outer circumferential surface of the rotor through a fitting hole of the fitting member;
- and
- injecting a bonding agent between the fitting member and the polygon mirror through a through hole provided in the fitting member to bond the fitting member and the polygon mirror to each other along respective surfaces perpendicular to a rotation axis.
