PURPOSE:To deliver surely normal balls of a pinball machine in a specified number of units by opening and closing operatively alternatively first and second switch member according to the operation control of an electric controller corresponding to operational requirements. CONSTITUTION:By operating a making controller according to the content of a desired game is thrust a second switch valve 42 in the upstream side of pat as a rod 41 of a second solenoid 40 is lowered to stop game balls. Thus as a rod 41 of a first solenoid 40 is lifted, a first switch valve 42 is shunted outside an outlet 36 to release the ball in the forefront. As a result, a specified number of balls in the path are expelled from the outlet 36. Then, when the rod 41 is lowered by the demagnetization of first solenoid 40, the first switch valve 42 is thrust into the outlet 36 to close it. Next, as the operation of second solenoid 40 is resumed, the rod 41 is lifted, so that the second switch valve 42 is shunted outside the path to release the game balls. Hence, the game balls at the inlet side flow into the path to be stopped by the first switch valve 42 and set to the original ball loading condition. |
