PCT No. PCT/GB91/02149 Sec. 371 Date Jun. 4, 1993 Sec. 102(e) Date Jun. 4, 1993 PCT Filed Dec. 4, 1991 PCT Pub. No. WO92/10814 PCT Pub. Date Jun. 25, 1992.A coin validator has a sensing arrangement disposed after an accept gate for detecting when a valid coin has moved past, and thus causing the triggering of the accumulation of credit. The sensing arrangement comprises a flap which is moved away from its normal position by the coin. If the coin is suspended on a string, the flap cannot move back to its normal position and therefore no credit is accumulated. |
