Abstract

The invention provides a polygon mirror scanner motor to which a polygon mirror can be attached with excellent precision. A distance between a motor rotary shaft and the pressurizing position of the polygon mirror (P) by a mirror fixing spring (101) is shorter than a distance between the motor rotary shaft and a position at which the polygon mirror (P) comes into contact with a seat surface (123).When a difference between an outer radius and an inner radius of the polygon mirror (P) is defined as A, and a distance, in a direction orthogonal to the motor rotary shaft, between the pressurizingposition of the mirror fixing spring (101) and the position of the seat surface (123) is defined as C, the relationship of 0<C< / =A / 4 is established. When a distance, in a direction orthogonal to the motor rotary shaft, between an inner diameter position of the polygon mirror (P) and the position of the seat surface (123) is defined as E, the relationship of A / 3< / =E< / =A / 2 is established.

Description

technical field [0001] The invention relates to a polygon mirror scanner motor, in particular to a polygon mirror scanner motor in which a polygon mirror is fixed by a mirror fixing spring. Background technique [0002] In laser writing systems such as laser printers, polygon mirror scanner motors are used as light deflectors. The polygon mirror scanner motor is a motor that rotates a polygon mirror (polygon mirror) at high speed and scans the laser light irradiated from the LD (laser diode) on the photoreceptor. [0003] Patent Document 1 below discloses a polygon mirror rotation driving device in which the lower surface of the polygon mirror 30 is arranged on the mirror mounting surface 26 of the rotor 20 . The upper surface of the polygon mirror 30 is fixed by the spring portion 505 of the mirror pressing member 50 fitted into the engaging groove of the rotor 20 . [0004] Patent Document 2 below discloses the same configuration as Patent Document 1 below. [0005] Pat...
