Abstract
An alternate target configuration is disclosed for a pinball game apparatus or the like, where two adjacent targets are mounted within a frame on the underside of the apparatus playfield, each adapted to move through a playfield opening between an exposed position above the playfield and a hidden position below the playfield. A linkage including an elongated member medially pivoted to the frame in the fashion of a seesaw is connected at its opposite ends to the respective targets, preferably when one target is exposed and the other target is hidden. The linkage is effective to shift both targets simultaneously from one alternate target position to another alternate target position where the other target is exposed and the one target is hidden. A spring toggles the seesaw linkage resiliently to the extreme limit of travel in each alternate target position. A motor overrides the spring toggle through an alternately reversed ratchet type connection to shift the seesaw linkage and reverse the positions of the targets. The motor is activated responsive to the exposed target being hit by the ball, and appropriate scoring apparatus is then energized.
