发明名称 Drop target assembly for pinball game
摘要 An improved drop target assembly provides first and second target surfaces for ball engagement at a given drop target location. Only one of the target surfaces is engageable at any given time. Preferably, both target surfaces are on a single, vertically movable support member such that dropping of the member to lower the first target surface to a below-playfield position drops the second target surface into a ball engageable position. One or more switch contacts are provided for indicating ball engagement with the target surfaces and the dropping of the first target surface to the below-playfield position. A housing is provided to shield the second target surface from view when the first target surface is in the above-playfield position.
