ABSTRACT:
A front loading disk player has an insertion slot for receiving variable sizes of disks to be played. As the disk is inserted it encounters pinch rollers on the free ends of pivoting arms. The pressure on the pinch rollers is sensed causing the arms and their support members to move transversely of the insertion direction to open up and accommodate the diameter of the specific disk while still pinching the edge of the disk. When the disk reaches a certain stage of insertion where the central portion is past the insertion slot, the pinch rollers, arms and support members take over and pull the disk all the way into the disk player and place the disk on a turntable.
