A ball bumper structure primarily intended for use in pinball type games can be constructed so as to utilize first and second members mounted so as to be capable of being pivoted relative to a platform. The first member includes a bumper surface exposed at the front of the platform and the second member includes another bumper surface located opposite the first bumper surface. When an object such as a ball contacts the first bumper surface the weight of the object and/or the force of such contact is employed to move the first movable member so as to discharge a latch structure. When the latch structure is disengaged an actuation structure including an impulse drive rapidly moves the second bumper surface toward the first. These surfaces are preferably tapered so that when a ball is caught between the two bumper surfaces as the second is being moved toward the first the ball will be forced outwardly away from the bumper structure.
