Claims

[Scope of utility model registration request]

A playback device for a disc-shaped information recording medium, which includes a turntable on which a disc-shaped information recording medium is mounted and driven to rotate, and a disc pressing means for pressing the disc-shaped information recording medium, the flange part and the flange part A leg part provided on the lower surface of the flange part to press the disk, and a thrust ball part protruding semispherically from the center part of the upper surface of the flange part to apply a pressing force to the disk and serve as a rotation axis are integrally molded. A pressing device for a disc-shaped information recording medium, characterized in that a clamper formed by the above-described method is rotatably provided at the tip of the disc pressing means.
