PROBLEM TO BE SOLVED: To provide a game machine by which cost is not raised even if additional functions for original game control are equipped by equipping a power source monitoring IC. SOLUTION: A power monitoring IC 902 to constitute the first power source monitoring circuit is mounted on the power source circuit board 910. The power monitoring IC 902 guide in the VSL power voltage and monitors the VSL power source voltage to detect generation of power OFF. Specifically, when the VSL power source voltage became below a prescribed value, a low power source voltage signal is outputted to inform of the power OFF. An electric parts control microcomputer recognizes the power OFF by a low power source voltage signal and processes necessary data storage. Because a circuit to realize additional functions such as data storing process is mounted on the power source circuit board 910, other circuit boards are not required to mount on such a circuit.
