PROBLEM TO BE SOLVED: To obtain a game machine which prevents an illegal tool from being inserted into an inner frame. SOLUTION: An unlocking piece 135 is exposed from the rear side of a tray unit 40 while the tray unit 40 is kept closed onto the inner frame 14 and is made to block with the unlocking piece 135 a path leading inside the inner frame 14 through a clearance between the tray unit 40 and the inner frame 14. Thus, even when the illegal tool is forced to advance from the clearance between the tray unit 40 and the inner frame 14, the tip part of the illegal tool hits the unlocking piece 135 to regulate its movement, thereby preventing the advancement of the illegal tool inside the inner frame 14.
