发明名称 Multi-position drop target.
摘要 <p>A drop target (18) for a pinball game has a target member (20) movable between raised and lowered positions and general intermediate positions. A solenoid mechanism (46) is employed to reset the display target to its raised position. Optional detectors (64, 65, 66) permit tracking of the position of the target so that appropriate scoring procedures can be implemented.</p>
