Abstract: To provide a game machine capable of suitably suppressing fraudulent conducts using a magnet and the like.SOLUTION: A value corresponding to a magnitude of a magnetic field is detected by detection means, and the value thus detected is calibrated by using a prescribed value for a calibration by calibration means.

The prescribed value for the calibration is set by setting means, and the setting is performed when a first movable body is operated, when a second movable body is not operated, and when a put-out motor is not operated. Therefore, the prescribed value for the calibration is set by taking into account of the effect of the magnetic field generating from the put-out motor, magnetic field detection means can be securely prevented from becoming unable to detect fraudulent magnetism (magnetic field) due to the fact that the setting has become an inadequate setting.SELECTED DRAWING: Figure 32
