TURN TABLE OF DISC PLAYER

摘要

PURPOSE: A turntable assembly of a disk player is provided to improve reliability by minimizing eccentricity and vibration in rotating a disk. CONSTITUTION: A rotatable shaft(11) of a spindle motor(10) is inserted into an axial groove(21) in the center. A turntable(20) has plural ribs(23) between annular guide members(22) around the axial groove. The turntable has a disk form having the guide members fitted into central connecting holes(110) of a disk(100). A doughnut-shaped magnet(25) is inserted into a guide groove(24) between the axial groove and the guide members. A pulley spindle(30) is mounted according to the turntable to clamp the disk. The pulley spindle has a yoke member(31) corresponding to the magnet. A hanging protrusion(23a) is protruded toward the axial groove. The ribs are pushed radially as the magnet rises up by tension with the yoke member to be hung to the hanging protrusion. Therefore, eccentricity in rotating the disk is minimized through the minimum gap among the connecting hole, the guide members and the ribs.
