Abstract
A disc device capable of achieving a slimming down of a tilt adjusting portion is provided. A tilt adjusting memberof a tilt adjusting portionmoves an optical pickup driving portionalong a guide faceto adjust a light beamemitted from an optical pickupsuch that an optical axisis set perpendicularly to a disc. Since the tilt adjusting memberis moved in a direction oblique to the guide faceand a direction perpendicular to the optical pickup driving portion, an amount of movement of the tilt adjusting membercan be reduced smaller than a necessary amount of tilt adjustment of the optical pickup driving portionand also a slimming down of the tilt adjusting portioncan be achieved. In this case, since a top end portion of the optical pickup driving portionis energized by an energizing memberto come into contact with the tilt adjusting memberand the guide face, this top end portion of the optical pickup driving portioncan be adjusted to come close to and go away from the discwithout wobbling and rattling.
