  • Patent number: 5244207
    Abstract: The invention relates to a gaming device comprising a gaming machine, a payout machinery controlled by the gaming machine and driven by a direct voltage motor, the operating time of which machinery proportional to the size of the payouts is controlled by a control signal (4) produced by the gaming machine, and means for feeding the motor with drive current depending on the control signal (4) of the gaming machine. To improve the reliability of the operation of the payout machinery, the control signal (4) is a digital code of at least 2 bits and the means for feeding the motor with current comprise a control register (5), a shift register (7), and a logic (8) for time control to reset the shift register output (Q) to zero after the control time set in the logic (8) for time control has expired, whereby the shift register (7) output (Q) comprises the drive current for the motor of the payout machinery either directly or through a current amplifier (11).
