PROBLEM TO BE SOLVED: To prevent game balls from falling from a ball send-out port in the opening operation of a front frame door in a game machine provided with a shutter plate for opening and closing the ball send-out port so as to be matched with the opening and closing of the front frame door. SOLUTION: A resilient contact concave part 64 is disposed on the surface of the shutter plate 40, and the shutter plate 40 is erected while bringing the resilient contact concave part 64 into resilient contact with the rear edge 51 of a ball leading-out and receiving part 50 when the ball leading-out and receiving part 50 is withdrawn to the front accompanying the opening operation of the front frame door 6. By such constitution, since the shutter plate 40 is promptly erected when opening the front frame door 6, the game ball x on the upstream side of the ball send-out port 34 is not put on the shutter plate 40 and the game ball x does not fall from the ball send-out port 34 when opening the front frame door 6.
