PROBLEM TO BE SOLVED: To provide a game machine capable of preventing damage due to a fraud by detecting abnormality due to the fraud in an early stage. SOLUTION: When a detection result of a human body detection sensor 27 shows the insertion of a player's hand, a main control board validates the operation input of a start lever 75 and, when the detection result of the human detection 207 shows no insertion of the player's hand, invalidates the operation input of the start lever 75 in the main control board 20. This constitution can prevent a fraudulent device from being attached to the start lever 75, prevent the start lever 75 from being operated by the fraudulent device, and detect abnormality due to the fraud in the early stage so as to prevent the damage due to the fraud.
