<P>PROBLEM TO BE SOLVED: To provide a game machine in which predetermined abnormality coping processing is performed on the basis of detection signals from an abnormal magnetism detection means for detecting the generation of abnormal magnetism, the game machine accurately detecting fraudulence. <P>SOLUTION: The abnormal magnetism detection means (magnetic sensor 60) includes: a reference magnetic state storage means 62 for storing a magnetic state in an arrangement environment as a reference magnetic state; and an abnormality signal output means 64 for outputting abnormality signals when the reference magnetic state and a magnetic state at the present point of time are compared and a difference out of a predetermined allowable range is detected. The reference magnetic state storage means 62 starts the processing of storing the magnetic state at the present point of time as the reference magnetic state on the basis of the supply of the power of the game machine 100. When a predetermined condition is established after the power of the game machine 100 is supplied, control for making the reference magnetic state storage means 62 start the processing of storing the magnetic state at the present point of time as a new reference magnetic state is performed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
