The sensor 40 is supported by the mounting frame 41. The optical axis is arranged to intersect at a position slightly downstream of the pachinko ball supported by 29 and at a position shifted from the center line of the ball passage 22. Then, the pachinko ball immediately after the restraint by the support portion 29 is released is arranged so as to detect the pachinko ball by blocking the optical axis. In other words, the pachinko ball stopped by the support portion 29 has not yet been detected without interrupting the optical axis.

Thus, below the operating body 25,
A closing member 43 as a fraud prevention member is pivotally supported on the inner peripheral side of the spherical passage 22 by a support shaft 42 so as to be swingable. The closing member 43 is formed in a substantially rectangular shape by a plate-shaped portion 43a facing the ball passage 22 via the shaft support 42 and an operating portion 43b, and the plate-shaped portion 43a always connects the ball passage 22 with the weight 44. The plate-shaped portion 43a is closed, the tip of the plate-shaped portion 43a is locked in the concave portion 45 as the upward movement restricting means formed inside the ball passage 22, and the upward movement is restricted. The abutment piece 46 abuts, and the plate-like portion 43a is tilted downward in the downflow direction of the pachinko ball to maintain a state in which the ball passage 22 is closed.

A lock means 47 is provided on the link member 26 and the solenoid 27 so that the closing member 43 cannot be operated. The locking means 47 is provided for the link member 2.

The pachinko ball supported by the support portion 29 is dispensed.
At this time, the engagement pin 31 and the long hole 30 are not in the contact position,
Since there is a gap in the rotation direction of the link member 26, the gap becomes the approach distance at the time of starting when the solenoid 27 is subjected to the maximum force to operate the operating body 25 that receives the ball pressure and is loaded, and the solenoid 27 is burdened. The operating body 25 can be reliably operated without applying the pressure.

In the above configuration, even if the closing member 43 is to be operated downward, the operating portion 43b of the closing member 43
Presses the stop piece 46, and the contact portion 51
Since the support portion 29 acts in the direction facing the ball passage 22 by pushing the lower right side of the operating body 25 upward against the zero, the rotation is prevented by the rotation restricting portion 38 and the closing member 43 is operated. Therefore, the act of illegally paying out pachinko balls can be prevented beforehand.
