OPTICAL SCANNING UNIT

摘要

PURPOSE: An optical scanning unit is provided to reduce the number of the assembly processes by causing a diffracted and deflected scan line to have one diffraction angle on the deflection disc. CONSTITUTION: A driver(20) is mounted on a base(10) to provide a rotation force. A light source module(40) irradiates light on an incident position of a deflection disc(30). A support(60) supports the light source module(40). A light module position adjuster(70) adjusts a position of the light source module(40). The support(60) is mounted on the lower side of the base(10) and includes an elastic member(63) for elastically biasing a mount(43) in one direction and a support piece(65) for supporting a guide surface(43a) to be contacted with the guide(15).
