发明名称 DISPOSITIF PREVENTIF ANTI-FIL POUR LA PROTECTION DU SYSTEME DE PAIEMENT DES APPAREILS AUTOMATIQUES ACTIONNES PAR DES PIECES DE MONNAIE (OU JETONS)
摘要 <p>A solid and fine thread of nylon is attached to the ends of a coin ramp. The diameter of the thread is just less than the interstice provided by the manufacturer. This allows coins to descend normally down the ramp since the additional friction is insignificant. Coins are prevented from descending which are attached to a thread for fraudulent retrieval of the coin since these coins are not able to rotate. The thread attached to the ramp may be attached to an alarm or security system.</p>
