Abstract

PURPOSE: To enable sure holding of a wafer so as to withstand quick acceleration by making the center of the wafer coincide with the rotating axis by a holding claw and holding the wafer to restrict turning of the wafer due to rotation.
CONSTITUTION: A wafer releasing device A is operated to turn holding claws 14a, 14b. After inserting a wafer 1 to a specified position, operation of the device A is stopped and the wafer 1 is held by three claws 14a, 14b, 14b by force of a tension spring 16. As the holding claw 14a is in contact with the orientation flat surface of the wafer 1, the center of the wafer 1 coincides easily with the rotation axis BC. When a rotation axis 11 is turned under this condition, holding claws 14a, 14b are subjected to turning force in the direction of arrows due to centrifugal force as they are pivotted to fulcrum pins below the center of gravity M allowing free turning. Thus, the claws hold the wafer 1 firmly, and turning of holding claws 14a, 14b is restricted by a stopper 17.
