SOLUTION: On a second power supply board 910B installed on the game board 6, a backup power source capable of supplying a voltage for making it possible to hold stored contents for a prescribed period to a fluctuation data storage means 55 for game control at least even if power supply to the game machine 1 is stopped and a power supply monitoring means 902 for monitoring the power of a prescribed voltage prepared on the second power supply board 910B and outputting detection signals indicating the fact that a detection condition relating to power supply stoppage to the game machine 1 is established when it is established, are loaded. In the case that it is required to detach the game board 6 due to model change, maintenance or the like, even if the second power supply board 910B is detached together with the game board 6, the contents stored in the fluctuation data storage means 55 for the game control can be held.
