Abstract: <P>PROBLEM TO BE SOLVED: To make it hard to have an illegal jackpot even if an illegal act like sending an illegal interruption signal, a reset signal or the like is conducted.  <P>SOLUTION: A CPU outputs a latch signal in an initialization process. The latch signal is given from an output port to a latch circuit. When the latch signal is input, the latch circuit inputs a value counted by a counter and latches the value. The CPU inputs the data (random number initial value latched by the latch circuit for determination) via an input port. Then, the input value is set in a counter for creation of a random 1 to create a random number for determining jackpot. The data latched by the latch circuit is a value (indefinite value) obtained by counting clock signals given from the second oscillation circuit outputting the clock signals asynchronous with the clock signal from the first oscillation circuit deciding the CPU motion frequency. So the initial value of the counter for creation of the random 1 also becomes an indefinite value.  <P>COPYRIGHT: (C)2009,JPO&INPIT
