Abstract

An optical scanning device includes a rotating polygon mirror, a motor, a substrate, a heat releasing member and a heat transfer member. The rotating polygon mirror deflection scans light emitting by a light source. The motor rotatively drives the rotating polygon mirror. The substrate has a drive circuit part for controlling the motor. The heat releasing member releases heat generated from the substrate. The heat transfer member is sandwiched between the substrate and the heat releasing member to be compressively deformed. A receiving portion that part of the heat transfer member compressively deformed enters is formed in a first part of the heat releasing member in which the heat transfer member is provided.

Description

technical field [0001] The present invention relates to an optical scanning device and an image forming device including the optical scanning device. Background technique [0002] There is known an optical scanning device used in an electrophotographic image forming apparatus such as a laser printer, in which laser light emitted from a light source is reflected and deflected by a polygon mirror rotating at high speed. The laser light reflected by the polygon mirror passes through the optical lens and scans the surface of the photosensitive drum. [0003] This optical scanning device includes a polygon mirror motor, a driver IC, and a substrate. The polygon mirror motor drives the polygon mirror to rotate. The driver IC is an IC (Integrated Circuit) for driving a polygon mirror motor. A driver IC is mounted on the substrate, and a bearing hole for receiving the rotation shaft of the polygon mirror motor is formed. [0004] In the above-mentioned optical scanning device, i...
