<P>PROBLEM TO BE SOLVED: To provide a game machine that properly prevent a magnet from being illegally used in a game. <P>SOLUTION: A value based on the size of a magnetic field is detected by a detection means. The value thus detected is calibrated by a calibration means by using a predetermined calibration value. The information or value based on the size of the magnetic field is output by an output means, on the basis of the value thus calibrated. The predetermined calibration value is set by a setting means, when a first movable body moves and a second movable object does not move. Thus, since the predetermined calibration value can be set to an appropriate value which is neither too large or small, an illegally applied magnetic field is properly detected by a magnetic field detection means, and the fraud using a magnet or the like is properly prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
