PROBLEM TO BE SOLVED: To provide a game machine in which abnormality of prescribed electrical components (switches, sensors, or the like) is reported through an abnormal state alarm means attached to an electric circuit board in the status that a main control board is separated or even in the status that the main control board is connected and the prescribed electrical components can easily be examined and can the examination load can remarkably be alleviated. SOLUTION: An abnormal state alarm circuit 100, including an LED (light emitting diode) which electrically connects a special central distribution board 71 in a plurality of electric circuit boards to at least another electric circuit board and reports the abnormality of the prescribed electrical components to the central distribution board 71 through lighting or lighting out, is installed, and the abnormality state alarm circuit 100 is structured to be able to operate in the state that the main control board is separated from the plurality of electric circuit boards.
