Patent ID: 7380254

Claim:
An optical pick-up feeding device comprising: a bracket defining an opening in a center thereof; a carrier supporting an optical pick-up thereon; a stepping motor with a worm screw for driving the carrier to move along the worm screw; two guiding rails provided at opposite sides of the opening; a connecting body comprising a first wall, a second wall extending upwardly from a longitudinal side of the first wall, and a connecting arm; and a buffer element comprising an elastic beam defined at a front end of the connecting body, a protrusion formed on one side of the elastic beam, and a slot defined at an inner side of the elastic beam, the beam being able to elastically deform so that it can bend into the slot, the protrusion extending outwardly from the beam; wherein the carrier is movably mounted between the guiding rails, the connecting body is mounted to the carrier and cooperates with the worm screw to transmit driving force from the stepping motor to the carrier, and the buffer element is configured for reducing vibration of the optical pick-up due to collision.
