Abstract
An adjusting mechanism of the guide rod of the optical pick-up in an optical disk drive, including an optical disk drive chassis, an elastic fixture of the optical pick-up module, a substrate of the optical pick-up module, the guide rods of the optical pick-up, and adjusting screws, wherein the substrate of the optical pick-up module is fixed on the optical disk drive chassis by the elastic fixture of the optical pick-up module, and the vibration can be released by virtue of the elasticity, and to provide the fixture of the guide rod of the optical pick-up. Therefore, the incident angle of the laser beam can be adjusted by adjusting the screws to eliminate deviation of the incident angle due to the error of manufacture, then the number of part can be reduce, and the assembly process can be simplified, so the added value can be promoted.
