ABSTRACT:
An optical pickup guide mechanism for guiding the optical pickup of an optical disk player is capable of correctly guiding the optical pickup regardless of the position of the optical pickup relative to the guide rails of the optical pickup guide mechanism. The optical pickup guide mechanism comprises a fixed guide rail, a movable guide rail, and a holding mechanism capable of holding the movable guide rail constantly in parallel to the fixed guide rail and of resiliently biasing the movable guide rail toward the fixed guide rail so that the movable guide rail can be translated. The movable rail is held always in parallel to the fixed guide rail regardless of the position of the optical pickup relative to the fixed guide rail and the movable guide rail and, consequently, the optical pickup can be guided for smooth movement radially to the center of the optical disk loaded on the optical disk player in a plane parallel to the optical disk, so that the optical pickup is able to function satisfactorily.
