  • Patent number: 6383070
    Abstract: A coin-sending device. The device includes a rotary disc (C3) that is set in a posture extending forwards and downwards with a first-side reservoir (C1) facing a coins-lump insertion part. An outlet of a second-side passage (C2) is open at a part extending backwards and upwards. Coins inserted from the coins-lump insertion part are finely received into the first-side reservoir (C1) facing the lump insertion part and then sequentially sent by the rotary disc (C3) extending forwards and downwards to be taken out through the outlet (C202) of the second-side passage (C2) opening on a part extending backwards and upwards. The outlet of coins can be set at a high position, thereby eliminating the necessity of holding a large drop between an inlet side and an outlet side of the coin-sending device.

  • Patent number: 6378685
    Abstract: A coin-receiving device including a coins-lump insertion part and a coin-sending device. A foreign objects separator catches foreign objects among inserted things and removes the foreign objects from coin-passage. The inserted items received from the coins-lump insertion part reach the coin-sending device through the foreign objects separator. Any foreign objects other than coins among the inserted items are caught by the separator before being processed by the coin-sending device and are removed from the coin-passage, thus being prevented from going together with following coins to the coin-sending device, and reducing clogging on passages of the coin-sending device and breakage of specific mechanisms.

  • Patent number: 6319126
    Abstract: A game machine wherein there is provided an attach-detach guide means D for guiding attaching and detaching of a coin-sending device C with respect to the game machine body 8 and causing an outlet passing C20 of the device C to be aligned with a communicating opening at the body 8 at an attach-finish position of the coin-sending device C with respect to the game machine body, thereby easily connecting passages and excellently receiving and transferring coins to a coin-payout hopper or the like arranged for following stages; upon detaching operation, the coin-sending device C is guided by the guide means D to be removed from the machine body 8, thereby simultaneously disengaging the outlet passage C20 from the communicating opening and providing simple separation of passages.

  • Patent number: 6312331
    Abstract: A coin-receiving device wherein a control switch AS is integrally formed on an assembly AA provided with a coins-lump insertion part A, so that inserting coins in a lump and following taking coins in the inside are carried out in a continuous series of actions; and the coins-lump insertion part A and control switch AS are handled as a single assembly AA thereby improving workability in assembly and upon exchanging parts.

  • Patent number: 6095916
    Abstract: A coin lifting mechanism employs a pair of rollers to lift coins reliably to an elevated position. The pair of rollers have spaced rotating surfaces that are resiliently urged toward one another and against opposing faces of the coin to hold the coin therebetween. The rotating surfaces rotate in opposite directions to produce a driving force in a direction to drive the coins one-by-one past the rollers. A coin lifting rail extends from a coin receiving end disposed adjacent the pair of rollers upward to a coin discharging end. The coin lifting rail has a coin passage which receives the coins from the rollers and guides the movement of the coins. The coins in the coin passage are stacked edge-to-edge and slidably move along the passage under the driving force generated by the rollers toward the coin discharging end.

  • Patent number: 6029794
    Abstract: A coin-sending device wherein coins can be lined up and discriminated at the same place, limitation of inner spaces of game machines or the like in which the coin-sending device is incorporated can be mitigated, and enlargement and complexity of their structures can be prevented, the coin-sending device comprising a coin-selection part 4 on a forcible-transfer passage 20 where a transfer force of a rotary disc 3 acts on coins sent from the rotary disc, coins are sent sequentially one by one to a second-side passage 2 following drive of the rotary disc 3, false coins IM at the coin-selection part 4 are removed through a removal opening 40 and only true coins are picked up at the coin-selection part 4, whereby coins are lined up and discriminated at the same place where the rotary disc 3 is provided, so that difference of height between an inlet of lump-insertion for coins and an outlet 202 of coins after discriminated can be made smaller, limitation of inner spaces of game machines or the like for mounting the
