PROBLEM TO BE SOLVED: To provide a game machine wherein a ball putout path is smoothly opened and closed following the opening operation of a front surface frame and balls are surely prevented from overflowing and jumping out of the game machine at the time of opening the front surface frame. SOLUTION: An inner frame to which the front surface frame is freely openably and closably mounted is provided with the ball putout path for guiding putout balls to a ball storage tray on the front surface side of the front surface frame and a shutter plate capable of opening and closing the ball putout path at the terminating end part of the ball putout path. The front surface frame and the shutter plate are provided with engaging means composed of an engaging guide in a long groove shape for instance and an engaging projection to be engaged with each other. The engaging position of the engaging means is displaced according to the opening angle of the front surface frame and the inner frame, and the ball putout path is set to either one of an opened state and a closed state.
