CLAMPING DEVICE FOR DISK

PURPOSE:To make the separating force of a clamper weak and to improve operability by making the tip of the shaft of a turntable abut on the central bottom part of the clamper and forming a gap between a magnet and the turntable when a disk is not loaded. CONSTITUTION:The clamper magnet 18 is fixed to a yoke 19. Then, the turntable 12 is attracted by the magnet 18 through the disk 17 and the disk 17 is rotated together with the table 12. When the disk 17 is not loaded, the tip part 4a of the motor shaft abuts on the central bottom part 20a of the clamper and the gap is formed between the magnet 18 and the table 12. Therefore, the force that the magnet 18 is separated from the table 12 is made weak and the difference from the force which separates the magnet 18 when the disk 17 is loaded is made small. Thus, a stable clamping state having the excellent operability is obtained.
