Abstract

An optical pick-up feeding device for easily adjusting an optical pick-up device to be perpendicular with respect to a surface of an optical disc. The optical pick-up feeding device includes a feeding section to feed the optical pick-up device, a guiding section to guide the optical pick-up device while it is fed by the feeding section, and an adjusting section to adjust the guiding section so that the optical axis of the optical pick-up device is perpendicular with respect to the surface of the optical disc. The feeding section has a lead screw to feed the optical pick-up device and a stepping motor to rotate the lead screw. The guiding section has a pair of guide shafts, and is adjusted by adjusting holders engaged with each end of one of the guide shafts and one end of the other guide shaft. Also, the optical axis of the optical pick-up device is adjusted to be perpendicular with respect to the surface of disc so that the recording/reproducing of data thereto/therefrom by an optical disc player is smoothly performed. Advantages are apparent in that the perpendicularity of the optical axis of the pick-up device is easily adjusted, vibration of the optical pick-up device is prevented, and the optical pick-up device is accurately positioned at an expected position to access the optical disc.
