<P>PROBLEM TO BE SOLVED: To accurately distinguish fraudulent vibration and normal vibration generated in a game machine. <P>SOLUTION: The game machine includes: a control board 123 for controlling a game; and a vibration detecting device 301 for outputting a pulsating detection voltage corresponding to vibration that is generated in the game machine and is at least at a predetermined value. The control board 123 includes: a frequency converter 307 for outputting a voltage corresponding to the frequency of the detection voltage as an analog voltage signal; a voltage converter 308 for outputting digital numerical value information corresponding to the voltage signal; and a determination means 361 of outputting notification information indicating a result obtained by comparing the numerical value information with a predetermined threshold. <P>COPYRIGHT: (C)2013,JPO&INPIT |
