Abstract:
A disk loading device for a disk player that completes preparation for playback of a disc by transporting the disk inserted into a disk loading slot on to a turntable and holding the disk on the turntable by lowering a clamper, comprising:a first lever rockably moved and reciprocable between a disk waiting position, at which the first lever is in contact with the edge of the disk at a position that the disk can be taken out, and a retreated position, at which the first lever is spaced apart from the disk during playback;a second lever rockably disposed on the same side of a disk loading path as the first lever such as to be capable of being in contact with the edge of the disk, the second lever being held, in an interlocked relation to the first lever, at an initial position in a zone permitting the insertion of the disk when the first lever is at the disk waiting position;a disk guide for setting an orbit of transport of the disk in contact with the edge of the disk on the side of the disk loading path opposite the first and second levers;lever biasing means for always biasing the second lever towards the disc and biasing the first lever away from a predetermined intermediate rocking position of unstable equilibrium of the first lever:clamper biasing means for always biasing the clamper toward the turntable;a timing mechanism for prohibiting the progress of the clamper toward the turntable and tentatively prohibiting the rocking movement of the first lever from a position, at which the first lever is in contact with the disk, to the retreated position;separating means for separating the second lever from a position thereof in contact with the disk in an interlocked relation to the rocking movement of the first lever from the position in contact with the disk to the retreated position; anddrive means including a motor as a drive source, for being started to operate the timing mechanism when the rocking movement of the first lever is prohibited by the timing mechanism;said timing mechanism being operative to retreat the first lever from the disk after the clamper has been brought closer to the turntable.
