<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 prescribed 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 work area data storage means (game control unit 30) of storing required data as a work area of operation processing relating to game control; and an initialization means (game control unit 30) of performing processing for initializing storage data of the work area data storage means in initialization operation input. Then, the reference magnetic state is stored based on power activation of the game machine and it is monitored whether the initialization operation input has been performed in parallel with processing for storing the reference magnetic state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
