PINBALL GAME

摘要

A play feature for a pinball machine includes one or more movable bumper posts placed near entrances to passages through which a ball will exit from the play of the game. When the bumper post is not actuated the ball can pass freely through a passage entrance. Actuation of the bumper post moves the post parallel to the surface of the playfield to a position hindering ball access to the passage. Bumper post motion may be sufficiently rapid to impart a considerable component of momentum in the direction of motion of the bumper post to the ball when the post contacts the ball.
