The signal from the detection switch 49 excites the rotary solenoid 30 of the first prize ball payout device 27 and the solenoid 48 of the first prize ball processing device 46. When the rotary solenoid 30 is excited, its drive disk 32 rotates in the direction shown by the arrow in FIG. 5, and the link 34 pushes the rear end of the movable case 29 upward to move the movable case 29 as shown by the chain line in FIG. The six prize balls are tilted and discharged through the ball discharge path 36 and the prize ball discharge gutter 45 to the upper ball tray 5. When the solenoid 48 is excited,
Since the plunger 50 is attracted against the coil spring 51, the valve member 47 is drawn as shown by the chain line in FIG. 7, and the game ball stopped on the lower valve plate 47b falls from the drop hole 52 into the winning ball passage 24 and is guided. It is discharged to the upper ball receiving tray 5 through the groove 66. That is,
When a game ball is won in the starting winning hole 12, a total of seven prize balls and one prize ball discharged from the movable case 29 are discharged to the upper ball tray 5 as prize balls. In addition, when the game balls are consecutively placed in the starting winning port 12 and overlapped on the lower valve plate 47b, when the lower winning ball falls from the drop hole 52, the upper winning ball is the upper valve plate. The drop is blocked by 47a, and the valve member 47 is returned to drop on the lower valve plate 47b, and the same operation as described above is repeated.

On the other hand, the game balls hit on the game board 9 are variable winning devices.
When 13 or the general winning opening 14 is won, the winning balls are collected in the winning ball collecting section 23 and guided from the exit to the second winning ball processing device 53. In the winning ball processing device 53, the plate cam 56 is rotated in the direction of the arrow in FIG. 8 by the drive of the motor 54, and the rocking body 59 is rocked on the cam surface. By swinging the swinging body 59, the winning ball is pushed out to the discharge port 58, and at the same time, the swinging piece 60 swings clockwise in FIG. 8 by the winning ball. For this reason, the vertical rod 65 is raised and the operating rod of the second prize ball dispensing device 28 is moved.
Since 43 is pushed upward, the discharge actuating body 41 moves upward as shown by the chain line in FIG. 5, lowering the tip of the upper valve 39 to close the upper end opening of the fixed case portion 38 and leaving the lower valve 40 in a free state. Seven prize balls in the straight sphere 44a and the straight sphere 44b
A total of 13 free gift balls out of 6 free gift balls
It is discharged to the upper ball receiving tray 5 via.

[Effects of the Invention] As described above, the pachinko gaming machine of the present invention, when the gaming ball wins the starting winning opening 12, the gaming ball first
