A projection strip (projection) 169 is formed so as to project into the guide trough 141 along the upper wall surface of the guide trough 141 side ball outflow portion 165 in the communication passage 168 communicating with 163.

According to such a configuration, FIG. 11 (a)
As shown in (b) and (c), when an incorrect member P _W such as a piano wire is inserted from the ball outlet 126 provided in the upper tray 16, the tip (entry end) of the incorrect member P _W is as described above. The guide trough 1 is also formed by the protruding strip 169 formed along the upper wall surface of the ball outflow portion 165 of the guide trough 141.
Intrusion into 41 is prevented.

Therefore, also in this case, the ball lending stopper member 1 is caused by the illegal member P _W entering the guide gutter 141.
43 is not pushed down, and the lending ball is guided by the illegal opening of the ball lending stopper member 143.
The situation in which a large amount of money is leaked out to 1 will be avoided.

Then, for example, the embodiment shown in FIG. 9 and the embodiment shown in FIG. 10 are used together, that is, as shown in FIG. 8 described above, a step is formed along the upper wall surface of the guide gutter 141 ball outflow portion 165 side. If the groove 166 is formed and the protruding piece 167 is formed so as to project into the ball flow down trough 163 along the lower wall surface of the guide trough 141 ball outflow portion 165, it is normally inserted from the ball outlet 126. The illegal member P _W is stopped by the protruding piece 167 protruding into the ball-flowing gutter 163 to prevent the illegal member P _W from entering the guide trough 141, and even if the protruding piece 167 is present.
Even if it enters without being stopped, it is stopped by the stepped groove 166 formed on the upper wall surface of the ball outflow portion 165 of the guide trough 141 and is prevented from entering into the guide trough 141.

In this embodiment, there are a prize ball payout device and a loan ball payout device, but since the prize ball payout device pays out the prize ball by the rotation of the screw, it is only necessary to insert an illegal member (foreign matter). Since it is impossible to pay out the game balls, if a fraud is performed, the photo sensor that detects the number of game balls paid out by the fraudulent member is made blind and the prize ball payout number 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 an effect of preventing fraud in such an act.

On the other hand, in the rental ball dispensing device of this embodiment, the ball lending stopper member is rotated by driving the solenoid to dispense the lending ball, and when the solenoid is not driven, it is easy to push up the stopper member with a foreign substance. Since the game ball can be discharged, there is an illegality preventing effect against such an act. In particular, since the rental ball payout device of the present embodiment is located near the ball outlet provided in the upper tray, there is a high possibility that foreign matter will be inserted, and it can be said that the fraud prevention effect is particularly large.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, a plurality of the above-mentioned protruding pieces are formed on the inner wall surface of the ball flow gutter to increase the frequency of catching a piano wire or the like, or when the tip of the piano wire has entered the ball flow gutter, a guide gutter for the ball gutter. It is also conceivable to use other means such as electrical / magnetic means such that the material is adsorbed on the wall surface opposite to the inlet.

[0055]

According to the pachinko gaming machine of the present invention, even if an illegal member such as a piano wire is illegally inserted from a ball outlet provided in the upper tray or the lower tray on the front of the gaming machine to cause the ball dispensing device to malfunction. The inflow of the illegal member is a ball outflow portion that is opened toward the side of the guide gutter provided on the ball outflow side of the ball dispensing device and a ball inflow portion that is opened on the side wall of the ball flow down gutter provided on the mechanism plate surface. In the vicinity of the communicating
Since the intruding end is stopped by the convex portion and the concave portion formed at the abutting portion of the guide gutter and the ball falling gutter, the intrusion of an illegal member is effectively prevented before the ball dispensing device. In particular, by combining the configurations of these convex portions and concave portions, even if the unauthorized member cannot be prevented from entering at only one place, the unauthorized member can be prevented from entering next. Since the invasion blocking mechanism of works, the illegal acquisition of the game ball can be reliably blocked.
