摘要 PCT No. PCT/DE91/00190 Sec. 371 Date Sep. 8, 1992 Sec. 102(e) Date Sep. 8, 1992 PCT Filed Mar. 2, 1991 PCT Pub. No. WO91/14147 PCT Pub. Date Sep. 19, 1991.A darts target for a game of darts has mobile segments marked with different scores and provided with holes for receiving the darts and is articulated inside a front door of a housing. When a dart strikes the segments, which are prevented from moving forward by retaining devices, the segments actuate a switch matrix which is arranged on a supporting disk and which automatically registers, totals and displays the scores by means of a switching system. The front door is articulated to the housing on one of its vertical longitudinal sides by a hinge. The supporting disk with the switch matrix is fastened to the rear face of the front door so that it can be folded back.
