PROBLEM TO BE SOLVED: To surely block the prevention of the fraudulence by adding the detection of vibrations and sounds above a prescribed level as requirements for altering the setting. SOLUTION: The game machine includes a vibration sensor VS for detecting vibrations disposed on a door 130-2 and a microphone MIC for gathering sounds disposed on the cabinet 120 of the game machine. When the vibrations and sounds detected with the vibration sensor VS and the microphone MIC exceed a predetermined threshold after a set value is defined by a prescribed operation, the defined set value is made valid. When the threshold is not exceeded, the defined set value is made invalid. COPYRIGHT: (C)2009,JPO&INPIT
