ABSTRACT:
A slot machine incorporates a coin dispenser, which has a discharge section that discharges a coin toward a discharge slot. A sensor is arranged at the discharge slot, and generates a detection signal upon detecting a coin. A counter counts the detection signal, to generate a count signal. A pay-out controller drives the discharge section in accordance with a pay-out signal, and prevents the discharge section from operating to complete the pay-out, when the count value equals a predetermined number of coins to be paid out. If the detecting signal is received before receiving the pay-out signal, the pay-out controller prevents the discharge section from operating, to protect the slot machine from a player's fraud. If the detection signal is received before receiving the pay-out signal or after completing the pay-out, the pay-out controller signals an error. A blocking plate is arranged to close the discharge slot. When pushed by the passing coin, the plate is opened to allow the coin to pass. Thereafter, the plate swings shut by gravity to prevent fraudulent operation of the machine by insertion of an implement backward through the slot.
