Further, as in this embodiment, the protrusion 167 is provided near the ball outflow portion 165 of the guide gutter 141, so that the intrusion of the unauthorized member _{PW into} the guide gutter 141 is more reliably prevented.

Further, in this embodiment, the protruding strip 167 is provided horizontally in the spherical downspout 163.
It may be provided in a slightly downwardly inclined shape toward the downstream side of 63. Then, the penetration end of the unauthorized member _PW is
If stopped by 67, it is no longer possible to invade any more, and fraudulent acts are surely prevented.

FIG. 11 shows a fraud prevention mechanism according to the third embodiment, in which a guide gutter 141 provided on the ball outflow side of the rental ball dispenser 80b and a ball flow gutter provided on the mechanism plate 250 surface. A ridge (projection) 169 is formed so as to project into the guide gutter 141 along the upper wall surface of the guide gutter 141 side ball outflow portion 165 in the communication passage 168 leading to the communication gutter 163.

According to such a configuration, FIG.
(B) As shown in (c), when an illegal member _PW such as a piano wire is inserted from the ball outlet 126 provided in the upper tray 16, the tip (intrusion end) of the illegal member _PW is set as described above. The guide gutter 1 is also formed by a ridge 169 formed along the upper wall surface of the ball outflow portion 165 of the guide gutter 141.
Intrusion into 41 is prevented.

Therefore, also in this case, the illegal member _PW enters the guide gutter 141 and the ball rental stopper member 1
43 is not pushed down, and the lending ball is released by the illegal opening of the ball lending stopper member 143.
This avoids a situation in which a large amount of money is paid out and paid out.

For example, the embodiment shown in FIG. 9 and the embodiment shown in FIG. 10 are used in combination, that is, as shown in FIG. When the groove 166 is formed and the projection 167 is formed to project into the ball flow down gutter 163 along the lower wall surface of the guide gutter 141 and the ball outflow portion 165, it is usually inserted from the ball outlet 126. The illegal member _PW is stopped by the protruding strip 167 projecting into the spherical downspout 163 to prevent the illegal member _PW from entering the guide gutter 141.
Even if it enters without being stopped, it is stopped by the step-shaped groove 166 formed in the upper wall surface of the ball outlet 165 of the guide gutter 141, and is prevented from entering the guide gutter 141.

In the present embodiment, there are a prize ball payout device and a rental ball payout device. However, since the prize ball payout device pays out the prize ball by rotating a screw, it is only necessary to insert an illegal member (foreign matter). It has become impossible to pay out game balls, and if fraud is performed, the photo sensor that detects the number of game balls paid out by the unauthorized member is blindfolded so that the number of prize ball paid out cannot be counted, The number of balls to be paid out is usually larger than the number of balls to be paid out, and there is a fraud prevention effect against such an act.

On the other hand, in the loaned ball dispensing apparatus of the present embodiment, the ball lending stopper member is rotated by driving the solenoid and the lending ball is dispensed, and when the solenoid is not driven, the stopper member is easily pushed up by a foreign substance. Since the game balls can be discharged, there is a fraud prevention effect against such actions. In particular, since the rental ball dispensing apparatus of the present embodiment is located near the ball exit provided on the upper tray, the possibility of foreign matter being inserted is high, and it can be said that the effect of preventing fraud is particularly large.

The present invention is not limited to the above embodiment at all, and various modifications can be made without departing from the gist of the present invention. For example, a plurality of the above-mentioned ridges are formed on the inner wall surface of the ball flow down gutter to increase the frequency of catching of a piano wire or the like, or the guide gutter of the ball flow down gutter when the tip of the piano wire enters the ball flow down gutter. It is also conceivable to employ other means such as electric, magnetic, or other means that is adsorbed on the wall opposite to the entrance.

[0057]

According to the pachinko game machine according to the first aspect of the present invention, the ball dispensing device inserts an illegal member such as a piano wire through a ball outlet provided in an upper tray or a lower tray in front of the gaming machine. Even if an erroneous operation is attempted, the intrusion of the illegal member can be effectively performed by the foreign matter intrusion prevention portion provided in the ball discharge path provided from the guide gutter provided on the ball outflow side of the ball discharge device to the ball flow down gutter provided on the mechanism plate surface. Will be blocked. Therefore, there is an advantage that illegal payout of the game ball to the player is prevented and unexpected damage to the game hall side is avoided.

Further, the foreign matter intrusion preventing portion of the present invention is provided in the vicinity of the communication portion between the guide gutter and the ball flow down gutter as in the second to fourth aspects, so that the intrusion of an illegal member can be made before the ball dispensing device. And the shape of the foreign matter intrusion prevention portion is a concave shape (step-like groove) for stopping the intrusion end of the unauthorized member or a convex shape protruding into the gutter of the guide gutter or the ball flow gutter. (Protrusions) can effectively prevent intrusion of unauthorized members. In particular, by combining the configurations of these foreign substance intrusion prevention sections, even if it is not possible to prevent the intrusion of the unauthorized member in only one place, the intrusion of the unauthorized member is prevented in the next prevention section, so that the two steps are taken. Since the intrusion prevention mechanism of the illegal member operates, illegal acquisition of the game ball can be surely prevented.

And as described in claim 5 of the present invention,
The foreign matter intrusion prevention means is not limited to the above embodiments, but can employ various methods, whereby the act of illegally acquiring game balls is effectively prohibited. The above benefits are enormous.
