[0007] As shown in FIG.
Is a rectangular cylindrical prize ball discharge guide port formed on the lower front surface of the sphere lead-out path 17, and 21 is a rectangular cylindrical prize ball discharge port formed on the front frame 1 and is an opening of the prize ball discharge guide port 20. A plurality of ball guiding ribs 22 are formed integrally on the inner peripheral surface of the edge (in the illustrated example, both inner side surfaces and the upper surface) along the ball flow direction. The prize ball discharge guide port 20
The step difference from the opening edge of the prize ball discharge port when the opening edge of the opening is fitted is eliminated. That is, prize ball discharge port 2
The prize ball discharge guide port 20 is fitted to the outer circumference of the prize 1 at the joint of the pillow. At this time, the step of the inner peripheral surface caused by the thickness of the opening edge of the prize ball discharge port 21 is eliminated by the ball guide rib 22, The ball is discharged without delay. In addition,
In this example, the ball guide ribs 22 are formed on both inner side surfaces and the upper surface of the prize ball discharge guide port 20, but may be formed on the lower surface in the same manner.

Reference numeral 23 denotes a lower cover for the overflow channel 9 formed on the mechanism plate 10 and reference numeral 24 denotes a lower cover for the lower flow passage 9.
The reinforcement ribs 25 formed on the inner surface of the lower edge portion
The prize ball that has flowed down in the overflow channel 9 hits the reinforcing ribs 24 and the sheet metal 25 with a sheet metal adhered to the bottom wall of the. Reference numeral 26 denotes a ball outlet cover provided at a lower portion of the mechanism plate 10.

In the pachinko machine constructed as described above, an unauthorized player intrudes a wire or the like from the opening 5 of the upper ball receiving tray 6, and a game board enters through a gap between the prize ball discharge guide port 20 and the prize ball discharge port 21. 2 and the prize ball discharging device 20 or the like, the prize ball discharge guide port 20 and the prize ball discharge port 21 are fitted in an intaglio shape with the opening edge of the prize ball discharge guide port 20 outside. Therefore, even if the gap is formed, it is difficult to penetrate the wire unless the tip of the wire is bent in a crank shape, so that it is almost impossible to perform such misconduct. In addition, since the ball guiding rib 22 is formed in spite of the inside of the prize ball discharge port 21 on the downstream side, the prize ball can flow on the ball guide rib 22 and smoothly flow into the prize ball discharge port 21. Therefore, even when a large number of prize balls discharged from the ball payout device 15 fill the prize ball discharge guide port 20, ball clogging hardly occurs.

In the embodiment shown in FIG. 5, the intrusion of wires and the like is made more complete by making the joining structure of the components more tight. That is, the measure unit 30 has a structure in which the back surface of the mechanism plate 10 and the unit base 14 are fitted by grooves and ridges, and the measure unit 31 has a front bank 1 formed with a jetty that can lock the game board 2. The measure section 32 is formed by forming an extended wall extending outside the prize ball discharge port 21 at the lower edge of the prize ball discharge guide port 20, and the measure section 33 includes the ball exit lid 26.
