Abstract
A planetary ball storage device for a pinball game according to the present invention consists of a horizontally disposed rotating wheel having a plurality of pinball receiving pockets arrayed on the periphery of the wheel. The game player, using the flippers, can direct a ball into an empty pocket when a pocket is in a ball receiving position after a predetermined game objective has been met. Balls are returned to the playfield by the utilization of a magnetic lifter arm controlled by the game microprocessor. The wheel is rotated by an electric motor and its position is detected by an optical switch assembly. A second optical switch assembly generates a signal to energize the magnetic lifter arm.
