Then, it rolls to the right along the right slope 34 and wins the general winning area through the general winning area entrance 79. The state in which the right electromagnet 45 is energized and magnetized is maintained until the next round. The winning of a game ball in the specific winning area is detected by a specific winning area passing detection switch 82, and the winning of a game ball in the general winning area is detected by a general winning area passing detection switch 83.

  When a game ball wins either the specific winning area or the general winning area of the big winning opening 8, 15 winning balls are paid out to the player. The opening / closing door 14 of the grand prize opening 8 is temporarily closed when either 30 seconds have elapsed after opening or there is an event of winning 10 balls, but the opening / closing door 14 opens. While there is a winning in the specific winning area, the open / close door 14 of the large winning opening 8 is opened again. The opening / closing door 14 can be continuously opened up to 16 times, and the opening / closing door 14 finishes opening 16 times or the opening / closing of the opening / closing door 14 causes the winning to the specific winning area. Is not detected by the specific winning area passing detection switch 82, the special game ends.

  When the special game ends, the solenoid 55 stops driving, the plunger 58 advances by the elastic force of the coil spring, and the drive transmission member 56 rotates in the direction opposite to that when the door 14 is opened. As the drive transmission member 56 rotates, the open / close door 14 rotates rearward with the pivot shaft portions 27 and 28 as fulcrums, and the special winning opening 8 is closed. At this time, since the rear surface contact portion 30 of the opening / closing door 14 contacts the rear surface side edge of the base member 11 below the opening 13, the closing posture of the opening / closing door 14 is reliably maintained.

  As described above, according to the above-described embodiment, the game balls won in the special winning opening 8 are reliably distributed to the left and right slopes 33 and 34 by magnetizing the left and right electromagnets 44 and 45. Therefore, the game ball can be surely won in the specific winning area or the general winning area at a predetermined timing set in advance. Further, since the left / right sorting mechanism 16 is configured in a non-contact manner, the load on the electromagnets 71 and 72 that are drive sources can be minimized, and the running cost can be reduced. Further, by distributing the game balls to the left and right in a non-contact manner, it becomes difficult for the player to determine which direction the game ball is distributed to the left and right, so there is no possibility that the player will be timed by stopping the game. .

  As shown in FIG. 6, the ball approach wall 91 of the ball receiving portion 24 is extended in the center direction so that the game ball 92 that has fallen on the ball receiving portion 24 is reliably guided to the center side of the ball receiving portion 24.
