PROBLEM TO BE SOLVED: To achieve a difficulty in targeting the specified random numbers for the avoidance of the fraudulence by irregularly switching the cycle of the counter. SOLUTION: The CPU 11 divides (divider 19) the frequency inputs from an oscillation source with the numerical data applied irregularly from outside to generate the random numbers, thereby raising a difficulty in estimating the frequency of updating the random numbers. It also detects the carry over of the random number counter 15 and further switches the frequency inputs when the given frequency of updating the random numbers is done, thereby equalizing the random number values appearing with the random number counter 15.
