Abstract
A serpentine ramp is rotatable about a horizontal axis between its center and its upper end to lift a pinball from a lower play surface to an upper play surface. A ball is directed from the lower surface into a ball receiving portion in the lower end of the ramp. This closes an optical switch causing the ramp to rotate between a receiving position and a discharge position. A ball disposed in the receiving portion rolls on the ramp to its upper end and then onto the upper surface. A second optical switch is closed by the return of the ramp to the receiving position which terminates the operation of the device.
