Device for reducing the backlash of optical pickup head of optical disk device

摘要

A device for reducing backlash of the transmission set of the optical pickup head of an optical disk device is provided. The device includes a guide rod penetrating an optical pickup head and a rack. The rack is engaged to a gear. The gear is driven by a motor so that the optical pickup head and the rack moves straight along the guide rod. The optical pickup head includes an elastic element. The elastic element apply a force to the rack so that the rack rotates around the guide rod and moves closer to the root of the gear to reduce the backlash between the gear and the rack and improve the partial deformation of the end of the rack due to the weak structure.
