PURPOSE:To pick a center hub for a flexible disk in a correct state. CONSTITUTION:A spindle 11 is made to lower to a center hub 1 and a pin 11 a at a tip is rushed into the center opening of a center part in the center hub 1 so as to execute centering. Next, a collect chuck 12 is made to lower and a tip pawl part 14a is rushed into the recessed side of the center part in the center hub 1. In this state, the flange part 3 of the center hub 1 is adsorbed by the magnet 16 embedded at the surface which is more external than the tip pawl part 14a so that the center hub 1 floats. Then, the spindle 11 is ascended. Thus, the collect chuck 12 opens by the actuation of a taper part 17 and the tip pawl part 14a comes to be pressurized contact with the surrounding wall of the rececced side in the center part of the center hub 1 so as to hold the center hub 1. |
