PROBLEM TO BE SOLVED: To provide a game machine which can widely monitor an area including neighborhood of electromagnetic driving means with a magnetic sensor while avoiding wrong error determination caused by operation of the electromagnetic driving means.SOLUTION: A game machine includes a movable body arranged in a game area, electromagnetic driving means which can drive a movable body by switching a non-excitation state to an excitation state, and a plurality of magnetic sensors MS1 to MS5 which can detect magnetism, and can perform error determination processing on the basis of detection signals from the magnetic sensors MS1 to MS5. In the error determination processing, the magnetic sensors MS1 to MS5 to use for the error determination are selected in accordance with a game state. For example, specific magnetic sensors MS2, MS3 in a prescribed position relation with respect to the electromagnetic driving means operable during a specific game state, error determination based on the detection signals is not performed during the specific game state.SELECTED DRAWING: Figure 16 |
