发明名称 DART MACHINE WITH ELECTRONIC MATRIX
摘要 A dart game for use with "safe" darts has enhanced electronic scorekeeping reliability. The dart game has a target including target sections for receiving thrown safe darts, the target sections being slidably mounted in a spider target frame. The spider and target sections are mounted in front of a pressure sensitive switch matrix for electronic sensing of dart hits. An apertured sheet of resilient material placed between the target sections and the switch matrix creates a gap through which an impacted target section must be displaced before it can compress and close an associated switch in the switch matrix, thereby enhancing the continuity and prolonging the duration of the switch contact. Ridges on the target section sides ensure ease of motion of the target section in the spider target frame.
