<p><P>PROBLEM TO BE SOLVED: To provide a game machine allowing to reduce influence by a magnetic field on movement of game balls even when a unit having a driving source for a big-prize-winning port is miniaturized. <P>SOLUTION: The game machine includes a door 651 for the big-prize-winning port, which is arranged in a game region 111 for opening and closing by rotating. A solenoid 81 for driving the door 651 includes a plunger 82 which slides and moves by using magnetic force, and is arranged so that a sliding and moving direction of the plunger 82 is approximately the same with a direction in which a rotating shaft 615a of the door 651 is extended. A space A1, through which the game ball enters the big-prize-winning port by opening the door 651 for the big-prize-winning port passes, is separated by a partitioning wall 656 from a space A2 where the solenoid 81 is arranged. A plate member 83 formed of magnetic material is arranged between the partitioning wall 656 and the solenoid 81, so as to cover an outer face of the solenoid 81. The plate member 83 prevents the game ball from being influenced by the magnetic force of the solenoid 81. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
