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.

摘要： Hall effect elements are placed in proximity to magnets in such a way that the position of the magnets relative to the Hall elements is a function of the position of a joystick controller. In this way, the position of the joystick can be "read" by a machine by reference to the Hall effect voltage.

摘要： A pinball machine having a playfield on which at least one drop target is supported for selective actuation relative to the playfield. The drop target includes a post having a conical shaped flange at its upper end, the post being moveable between a position wherein the flange and a portion of the post are disposed above the playfield for impingement by a game ball, and being responsive to impact by the game ball for movement to a position wherein a planar surface on the upper flange is substantially flush with the playfield so as to enable the game ball to pass freely thereover. Movement of the drop target from its raised position to its lowered position upon impact by a game ball serves to propel the ball away from the target.
摘要翻译：一种具有游戏场的弹球机，在该场地上至少有一个落下目标被支撑以便相对于该场地选择性地致动。下落目标包括在其上端具有圆锥形凸缘的柱，所述柱可以在凸缘和一部分柱体设置在游隙之上的位置之间移动，以便由游戏球冲击，并且响应于冲击用于运动的游戏球，其中上凸缘上的平坦表面与游戏场基本齐平，以使得游戏球能够自由地通过。在由游戏球撞击时，下落目标从升高位置向下降位置的移动用于将球推离目标。
