Abstract: A disk gripper has a rotary actuator with a horizontally supported shaft, a swing arm which is attached to and can rotate with this shaft and a finger arm which is connected to the swing arm such that the connected arms together extend radially from the shaft. Gripper fingers on the finger arm have mutually coplanar flat outer surfaces which point downward when the arms are in the horizontally extended position. The gripper fingers are provided with grooves and are movable toward or away from one another while their flat outer surfaces slidingly move over a horizontal support surface such that a disk lying on this surface can be engaged in these grooves or disengaged therefrom. The swing arm and the finger arm are slidable within a limited distance with respect to each other in a direction perpendicular to their extension.
