Patent ID: 8060897

Claim:
A restraining device of optical disk drive disposed inside an optical disk drive, the optical disk drive being disposed with a traverse, where a transmission unit rotates a roller to load/unload a disc and drives a slider to move the roller, the transmission unit being disposed with a restraining device that moves with the roller; wherein when the optical disk drive does not carry a disc, the slider moves to restrain the traverse and release the roller, while the restraining device moves close to the traverse to retrain the vibration range of the traverse; when the optical disk drive carries a disc, the slider moves to release the traverse and push down the roller to move the restraining device away from the vibration range of the traverse; and wherein the transmission unit further includes a gear transmission set disposed on the side of the traverse, the gear transmission set comprising a first gear transmission member, a second gear transmission member, and a linkage gear that transmit interactively, the first gear transmission member being used to rotate the roller, the second gear transmission member being used to drive the slider, the linkage gear being linked up with the first gear transmission member and the second gear transmission member with an inner positioning plate and an outer positioning plate respectively to move interactively with the first gear transmission member and the second gear transmission member, the restraining device being disposed in the positioning plate.
