<P>PROBLEM TO BE SOLVED: To provide a game machine with a fraud detecting mechanism capable of reliably preventing fraud in which a ball with a thread is used. <P>SOLUTION: The fraud detecting mechanism detecting a fraud in which a ball with a thread is used includes: a path which guides a ball taken from an inlet and which has a bypass flow path; a slit which is positioned on a wall of an inner peripheral side of the bypass flow path; and a detection unit which is positioned at a more inner peripheral side than the bypass flow path and which detects the thread connected to the ball. <P>COPYRIGHT: (C)2012,JPO&INPIT |
