Abstract

PURPOSE:To make loading and unloading of a disc easy, by providing a clamper which makes the disc on a supporting member playing and giving a taper to the clamper. CONSTITUTION:A clamp arm 63 is fitted freely rotatably to a reception stand 90 provided for a carrier by taking an axis 91 as a supporting point and energized toward the opening direction (clockwise) with a spring 92. The amount of rotation of the arm 63 is restricted with a pin 93 projected from a receiving stand 90. The arm 63 is fitted with a guide 95 and a guide pin 96 provided with a magnetic material 94 at the tip. The clamper 62 formed in almost circular cone shape with taper has a ribbon magnet 98 at the bottom and a magnetic material 99 at the head and is freely inserted at the guide 95 to a clamp arm 63. The clamper 62 and the clamp arm 63 are made of a nonmagnetic material.
