PROBLEM TO BE SOLVED: To provide a game machine capable of preventing the leak when an earthquake occurs. SOLUTION: The game machine comprises motors 400, buttons and sensors 500, a main circuit 71, a power supply device 210 for feeding electric power to the above, and a cabinet for storing the above. The game machine also has a P-wave sensor 15 for detecting the quake of the cabinet, a P-wave detecting part 232, an S-wave sensor 152, an S-wave detecting part 233, and a switch 220 and a power feeding stopping part 231 for determining whether an earthquake occurred or not based on the detected quake and stopping the power supply from the power feeding device 210 if it is determined that the earthquake occurred.
