<p>PROBLEM TO BE SOLVED: To accomplish the winning-prize device of a pinball machine and a new electromagnetic solenoid driving device with which the on-off member of the winning-prize device of a pinball machine can be driven smoothly, the on-off member can be driven at large stroke or the driving stroke can be changed easily, and manufacturing cost can be cut down by simplifying an assembling work. SOLUTION: The solenoid coil 18, in which a movable core 30 is inserted to a core hole 11a, is inserted to an electromagnetic yoke 20, and a coil spring 31 is interposed between the electromagnetic yoke 20 and the driving board 40 which is connected to the movable core 30. A mounting board 50 is fixed to the electromagnetic yoke 20 by a fixing screw 52, and a guide piece 60 is fixed to the lower part of the above-mentioned mounting board 50. The guide piece 60 is engaged to the notched part 41 of the driving board 40, and the guide piece 60 is formed in such a manner that the driving board 40 is guided upward and downward to the position of its stopping part 62.</p> |
