PROBLEM TO BE SOLVED: To provide a game machine capable of accurately detecting fraudulent actions. SOLUTION: The game machine is provided with a winning device, a control board 81 and a reporting means. The winning device is provided with a magnetic sensor 91 for detecting magnetism and outputting magnetic detection signals. The control board 81 is provided with a detection time measuring means 81a, a detection time judging means 81a and a reporting signal output means 81a. The detection time measuring means 81a measures the magnetic detection time of the magnetic sensor 91 on the basis of the inputted magnetic detection signals. The detection time judging means 81a judges whether or not the magnetic detection time is longer than 300ms. The reporting signal output means 81a outputs first reporting signals to the reporting means when it is judged that the magnetic detection time is longer than 300ms. The reporting means reports that fraudulence is performed on the basis of the first reporting signals. COPYRIGHT: (C)2007,JPO&INPIT
