Patent ID: 7213251

Claim:
A tilt adjusting apparatus for an optical disc player to adjust a tilt of an optical pickup so that a light beam emitted from the optical pickup is perpendicularly incident on a recording surface of a disc, the tilt adjusting apparatus comprising: adjusting ends positioned on at least first ends of two guide shafts that are respectively disposed approximately parallel to each other at first and second sides of the optical pickup to guide reciprocating motion of the optical pickup; and for each adjusting end, the tilt adjusting apparatus further comprises an elastic member positioned adjacent to the adjusting end, contacting a first location of the adjusting end, and applying an elastic force to the adjusting end in a first direction, a stopper opposing a second location of the adjusting end opposite the first location, having a screw coupling hole therein passing through first and second portions of the stopper, the second portion of the stopper limiting adjustment of the adjusting end in the first direction when the adjusting end engages the second portion of the stopper, so that the optical pickup does not contact a lower surface of the disc, and an adjusting screw coupled to the screw coupling hole in the stopper, a first portion of the adjusting screw contacting the adjusting end and adjusting the adjusting end in a second direction opposite the first direction when the adjusting screw is rotated in a first rotational direction, and thereby adjusting the inclination of the respective guide shaft.
