Disk player and turntable incorporating self-compensating dynamic balancer clamper incorporating self-compensating dynamic balancer and spindle motor incorporating self compensating dynamic balancer adopted for disk player

摘要

PURPOSE: A disc player, and a self-compensating dynamic balancer integrating turntable, a self-compensating dynamic balancer integrating clamper, and a self-compensating dynamic balancer integrating spindle motor employed in the disc player are provided to restrain the vibration generated by the rotation of a disc by compensating the eccentricity by a balancer biasing oppositely against the eccentric mass. CONSTITUTION: A disc player includes a self-compensating dynamic balancer(400) which has a rotation plate(410), a plurality of main rotation pendulums(413) supported to the rotation plate at a side for elastic pendulum motion with respect to the supported side and displacing against the eccentricity, and an auxiliary rotation pendulum supported to the main rotation pendulum at a side for elastic pendulum motion with respect to the supported side, wherein each of the main rotation pendulums has a supporting part(413a) fixed to the rotation plate, and a plurality of pendulum parts(413c) symmetrically connected to the supporting part by predetermined elastic pieces(413b) to move elastically.
