ABSTRACT:
A pinball machine comprises a position controller and a movable feature on the pinball machine. The position controller comprises a servomotor connected in operative relation to a shaft. The movable features connect to the shaft and are movable between several positions by the shaft. Circuitry is provided to produce a signal to command movement of the feature to one of the positions in a manner responsive to an event taking place in the pinball machine. Electronic circuitry causes the servomotor to move the shaft to a specific position in response to the signal, without the need for mechanical switches. Specifically, a plate-like, movable obscurer for the flippers is disclosed as the movable feature, although other types of movable features are discussed.
