摘要: An upper clamping device and a lower clamping device are provided for clamping a double-sided optical disc in cooperation with the upper clamping device. An annular holder is axially movably provided in the upper clamping device. A plurality of spheres are radially movably mounted on the holder. A hub having a slant at a periphery thereof is axially movably provided. When the hub is downwardly moved the slant urges the spheres to engage them with an inside wall of a center hole of the optical disc. Thus, the optical disc is centered.
