<P>PROBLEM TO BE SOLVED: To detect fraudulence accurately in a game machine including an abnormal magnetism detection means of detecting generation of abnormal magnetism. <P>SOLUTION: The abnormal magnetism detection means (magnetic sensor 60) includes: a reference magnetic state storage means 62 of storing a magnetic state of an arrangement environment as a reference magnetic state; and an abnormal signal output means 64 of comparing a reference magnetic state with a magnetic state at this stage, and of outputting an abnormal signal in detection of a difference deviating from a predetermined allowable range. Further, a game control unit 30 includes a storage completion determination means (game control unit 30) of determining whether the reference magnetic state storage means completes storing the reference magnetic state in a prescribed period after power is turned on, and transmits a storage completion command to a slave control unit (performance control unit 40) when it is determined that storage of the reference magnetic state has been completed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
