PROBLEM TO BE SOLVED: To intensify noise countermeasures and to prevent noise from adversely affecting various control boards or the like for performing game control by effectively absorbing the noise by static electricity charged to a game ball and a receiving member for receiving the game ball overflowing from a ball tray and guiding it to a lower tray. SOLUTION: A conductive member 85 in a thin plate shape is provided on the upper surface of the bottom wall part 84a of the receiving member 84, a noise absorption circuit for absorbing the noise by the static electricity is provided on a power source board and the conductive member 85 and the noise absorption circuit are connected by a ground line 137. Thus, not only the static electricity charged to the game ball overflowing from the ball tray but also the static electricity charged to the receiving member 84 are effectively and surely eliminated and the noise by the static electricity is surely absorbed in the noise absorption circuit.
