Abstract: 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.

Abstract: A loading mechanism for a recording/reproducing apparatus includes a loading motor, a pulley unit, a gear unit, a cam member, a manual ejection member, and a tray. The pulley unit includes a small pulley wheel, a large pulley wheel, and a belt connecting the small pulley wheel and the large pulley wheel. The gear unit includes a drive gear and a driven gear in mesh with each other. The driven gear includes a large gear and a pinion, the large gear being in mesh with the drive gear. The tray includes a gear rack in mesh with the pinion of driven gear of the gear unit. A hardness of the driven gear is less than hardnesses of corresponding portions of the cam member and the gear rack engaging therewith, therefore the loading mechanism operates with low noise. Furthermore, the two-grade speed reduction configuration requires relatively few components.
