  • Patent number: 6086472
    Abstract: A throw-in coin discriminator is shown which includes a hopper to receive the coins to be discriminated. From the hopper a conveyor conveys the coins to a coin handling mechanism. A roller unstacks any stacked coins. The unstacked coins are deposited on a second conveyor which is traveling at a faster speed to singularize the coins. The coins pass a series of detectors to determine, for example, whether the coins are genuine or counterfeit. The coin handling mechanism directs authentic coins in a first direction and counterfeit coins in a second direction.
