发明名称 ELECTRONIC SCORING DART BOARD
摘要 A target for use with a projectile has a web defining a target face and has a depth. The web also defines one or more segments within the web that open toward the target face. One or more cups are mounted for sliding within the web and substantially fill the target face of one or more segments of the web. Each of the cups has one or more resilient cushions, between each cup and the back board. Each cushion has one or more electroconductive areas. The back board has an array of switch contacts on a pad forming an electrical switch. The projectile impacts a cup at the target face with sufficient force to cause the cup for that insert to slide within the web and have the electroconductive area of the one or more cushion contact the switch contacts on the pad beneath that cup, resulting in closing of the electrical switch defined by the switch contact. The one or more resilient cushions beneath that cup return the cup substantially to its original position.
