PROBLEM TO BE SOLVED: To provide a game machine allowing a payoff control means to reliably recognize all commands from a game control means. SOLUTION: A payoff control INT signal from a main substrate is inputted to the interrupt terminal of a payoff control CPU. When the INT signal from the main substrate is set to an on-state, an interrupt is applied to the payoff control CPU, and the reception process of a payoff control command is started. When the interrupt occurs, a maskable interrupt is prevented from further occurring on the payoff control CPU unless an interrupt is permitted by software. The interrupt is permitted at the last of the command reception interrupt process, whereby no other interrupt process is executed during the command reception process.
