Disk chucking apparatus of a disk player

摘要

A disk chucking apparatus of a disk player comprises a chucking plate including a cylindrical hollow portion at the bottom thereof, a tapered surface formed around the outer peripheral surface of the hollow portion and a protrusion formed at the lowest end of the tapered surface. A clamping ring is movably fitted around the tapered surface and supported by the protrusion. A turntable includes a compartment at the center portion thereof and a lifting ring for lifting the clamping ring. A head is located in the compartment and connected to a spindle motor via a shaft. A sliding ring is slidably fitted with the head; and a spring is located under the sliding ring. The chucking plate and the turntable are made of plastic materials. The disk chucking apparatus avoids an abrupt impact on the disk as the chucking plate is gradually engaged with the turntable with a regular pressure, thereby to achieve a stable chucking operation.
