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.
Claims14
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 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 method for assembling a polygon mirror scanner motor, the method comprising:
- mounting a rotor on a stator,
- fitting a polygon mirror through a fitting hole of the outer circumferential surface of a rotor boss,
- mounting a polygon mirror on a rotor table.
A method for assembling a polygon mirror scanner motor, the method comprising:
- screwing a cap down to a rotor of a mirror holding member;
- compressing a spring between the cap and a polygon mirror by a thrust-direction force applied from the cap;
- attaching the polygon mirror to the rotor by a force from the compressed spring;
- and
- bonding the polygon mirror to the rotor by applying a bonding agent.
