DESCRIPTION:
BRIEF SUMMARY
This 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 produced by the gaming machine, and means for feeding the motor with drive current depending on the control signal of the gaming machine.
In conventional gaming devices of the type described above, the motor of the payout machinery is controlled by a signal given by the gaming machine, which signal feeds the motor of the payout machinery directly with drive current through a suitable switch, e.g. a transistor. This way of controlling the payout machinery is relatively sensitive to external disturbance. Such disturbance can occur for instance by electromagnetic pulses, by spraying chemicals or by changing the drive current. The intention is then either to make the motor of the payout machinery start without cause or to prevent a correct payout operation from ending.
The object of the present invention is to provide a gaming device, in which the operation of the payout machinery is substantially more reliable than before and which is not to the extent sensitive to external disturbance as the prior art gaming devices.
This is achieved by means of the gaming device of the invention, which is characterized in that the control signal is a digital code of at least 2 bits and the means for feeding the motor with current comprise a control register with an input receiving the control signal and with an output, the state of which depends on the value of the control signal, a shift register with an output, a reset input and a data input receiving the output of the control register, and a logic for time control with a starting input connected to the control register and with an output connected to the reset input of the shift register to reset the shift register output to zero after the control time set in the logic for time control has expired, whereby the shift register output comprises the drive current for the motor of the payout machinery either directly or through a current amplifier.
By substituting the conventional signal of on/off type given by the gaming machine earlier for a digitally coded control code, it is possible to substantially eliminate the possibility that the gaming machine unintentionally or as a result of a possible disturbance would give a control code for starting a payout. By forming the very circuit feeding the motor of the payout machinery with drive current in such a way that, firstly, it only reacts to a correct control code and secondly, it controls its own function as per time by means of a logic for time control, the possibility is substantially eliminated that stopping the payout for some reason would be prevented.
To reduce the possibilities of external disturbance further, the procedure according to the invention is that the control register, the shift register and the logic for time control are arranged in the same integrated circuit, which substantially eliminates the possibility of preventing the operation of the logic for time control and makes an external disturbance of also other mutual connections between these parts impossible.
In the following, the gaming device of the invention is described in greater detail referring to the enclosed drawing, in which
