  • Patent number: 5530730
    Abstract: A medal counting apparatus installed in a game parlor for counting medals which a game player has won, is disclosed. The medal counting apparatus comprises a counter for counting the medals, a medal supplying mechanism for receiving the medals to be dumped and for supplying them sequentially to the counter, a dump restraining unit for restraining the medals from being dumped into the medal supplying mechanism and a control unit for controlling operations of the medal supplying mechanism and the dump restraining unit. The medal supply control means puts the medal supplying mechanism into a stopped state when the dump restraining unit restrains the medals from being dumped and into an operation state when the dump restraining unit permits dumping of the medals. The control unit also instructs the dump restraining unit to close the receiving hopper when a medal dump restraining signal is input from the outside or the counter has not been used for a certain period of time.

  • Patent number: 5503383
    Abstract: A paper strip conveying apparatus provided along an objective conveying path, comprising an endless belt having its periphery in contact with one of the two faces of the paper strip and a plurality of pulleys provided along the conveying path so that their peripheries come in contact with the other face of the paper strip, between which a paper strip is pinched and conveyed. The object of the present invention is to shorten the length of the electric wire through which static electricity charged in a pulley flows out. In the present invention, both a pulley fixing board which supports the pulleys and a main body frame formed along the conveying path are formed of conductive material, and are electrically connected by a conductor.

  • Patent number: 5501446
    Abstract: A paper strip transporting apparatus includes a drive pulley and a driven pulley (22, 23) which are separated from each other; a belt (25) which is disposed between and around the pulleys; a plurality of transporting rollers (27, 28) disposed along the belt (25) between the drive and driven pulleys (22, 23); and a drive unit (21) for driving drive pulley (22). Either one of the transporting rollers (27, 28) and the belt (25) has a convex portion and the other has a concave portion corresponding thereto at respective facing areas thereof. The transporting rollers (27, 28) are disposed with respect to the belt (25) so that the convex portion is positioned within the concave portion in a non-contacting relationship therebetween.

  • Patent number: 5492317
    Abstract: The paper strip conveying apparatus includes a conveying roller which is provided in such a manner that the outer peripheral plane comes into contact with one surface of a paper strip, a roller drive mechanism which rotates the conveying roller and a paper strip biasing member which is provided in such a manner that the tip portion comes into contact with the other surface of the paper strip. A convex portion is formed circularly along the outer peripheral plane of the conveying roller. The paper strip biasing member has a concave portion into which the convex portion of the conveying roller fits without contact at the tip portion. When the paper strip is sandwiched between the conveying roller and the paper strip biasing member, since the convex portion of the conveying roller fits into the concave portion of the paper strip biasing member, the paper strip is forcedly flexed so as to be urged onto the convex portion of the conveying roller and conveyed by the rotation of the conveying roller.

  • Patent number: 5492326
    Abstract: A game machine island comprising ball lending machines each disposed between two adjoining game machines and ball lending machines of the same type arranged at the ends of the line of the game machines, respectively. A drive unit and a driven unit have introducing paths communicating with bank note discharging slots of the ball lending machines arranged at the ends of the island, respectively, for directly introducing bank notes discharged from the ball lending machines to the conveying belt. In the construction of the island, the installation and the wiring is carried out efficiently, and the workability of the installation can be enhanced, and the cost can be reduced.
