Patent attributes
An optical pick-up feeding device (100) includes a bracket (1) defining an opening (10), a carrier (41) supporting an optical pick-up (3), a stepping motor (42) having a worm screw (420) for driving the carrier, a pair of guide rails (43) for guiding the carrier, and a connecting body (44) for transmitting driving force from the worm screw to the carrier. A slot (446) and a beam (447) are defined at a front end of the connecting body. A protrusion (445) extends horizontally outwardly from a middle of the beam. The protrusion can elastically bend into the slot when a force is applied on the protrusion. When the protrusion collides with an inside wall of the bracket at the opening, the protrusion presses the beam to bend into the slot, thereby translating the force of the collision into elastic deformation force of the beam. This reduces vibration of the optical pick-up.
