The rotation of the sprocket 42 by the prize ball b in the supply passage 38a is stopped, and the payout of the prize ball b is stopped.

Next, for example, when a pachinko ball is won in a winning opening (not shown) mounted on the game board 3 and the solenoid 44 is excited by the signal, a plan as shown in FIG. The jar 52 is sucked, the lever member 43 tilts, and the claw 50 and the locking piece 45a are disengaged. Then, the sprocket 42 is made rotatable and the solenoid 44 is instantly demagnetized to move the lever member 43 to the position shown in FIG.
Return to the horizontal state of (a). This allows the sprocket 42
Is rotated once by the prize sphere b, and five prize spheres b fitted in the respective recesses 42a are continuously discharged to the outflow passage 41 at a time, and the claws 50 are engaged with the locking pieces 45a again to allow the sprocket 42 to move. Stop spinning. The number of the prize balls b to be paid out is detected by the sensors 65a and 65b.

Next, in the second prize ball payout device 39b for paying out prize balls one by one, the solenoid 55 is always demagnetized and the plunger 61 is projected downward as shown in FIG. 13A.

Then, when the winning ball is generated, the solenoid 5
When 5 is energized, the suction plunger 61 as shown in FIG. 13 (b), the movable member 54 projects into the accommodation portion 57, at its convex arcuate face 54a receiving the next prize ball b _2. At the same time, the prize ball b ₁ that was fitted into the concave arc surface 54b
Is released to the outflow passage 41 as the movable body 54 swings, as shown in FIG. After that, the same operation is repeated and the prize balls are paid out one by one. Further, the number of these prize balls b ₁ and b ₂ is the same as the above, and the number of them is the detection sensor 65.
a, 65b.

Therefore, for example, when seven prize balls b are paid out due to the generation of winning balls, the sprocket 42 is rotated once and the movable body 54 is reciprocated twice at the same time, so that five and two prize balls are obtained. The prize ball b is paid out. Further, when paying out 13 prize balls b, the sprocket 42 is rotated twice, and at the same time, the movable body 54 is reciprocated three times to pay out 10 and 3 prize balls respectively. In this way, different prize balls can be paid out depending on the winning balls.

Note that, in particular, when the prize ball runs out of ball in the supply passage 38a, the sprocket 42 becomes free, but the weight 46 provided on the cam disk 45 is always shown in FIG. 12 (c).
Since it is positioned at the lower side and stopped as shown in FIG. 3, even if the prize ball supplied later fits into the recess 42a of the sprocket 42 and tries to rotate the sprocket 42 in the arrow direction, the lever member 43 immediately Claw 50 engages with the locking piece 45a of the cam disc 45 to stop the rotation of the sprocket 42. Therefore, useless dropping of the prize balls is prevented, and five prize balls are surely paid out.
