Spindle retracting mechanism for disc record player

Image Number 5 for United States Patent #4305145.

In a video disc player, the turntable spindle is held in a raised position such that it is maintained in engagement with the record center hole when the turntable is lowered to transfer a spinning record from the turntable to the receiver pads. A mechanism, responsive to the insertion of an empty jacket into the player, retracts the spindle to allow the insertion of the jacket into the player free from interference with the spindle.
