Abstract
The device for automatically turning a disc over includes a disc grasping mechanism which comprises a main arm, sub-arms mounted on the main arm to grasp the disc by the circumferential edge with the aid of springs, and electromagnets disposed to control each sub-arm against the action of the springs. The device further includes an automatic mechanism for turning the disc over and which comprises a main rotary shaft connected to the main arm at its middle portion and supported by an anti-friction bearing, a cam means disposed to swing the rotary shaft, a driving shaft with the cam means and a gear fixedly mounted on, the gear being in mesh with another gear fixedly mounted on the main rotary shaft to rotate the latter gear, and a driving motor operatively connected to the driving shaft. The disc grasping mechanism and the automatic mechanism for turning a disc over are interconnected with a full-automatic record player mechanism so that they are operative in an interlocking relation with the record player mechanism.
