In this embodiment, an optical sensor will be described as the ball counting sensor, but sensors of other detection types such as an electromagnetic type and a capacitance type may be used.
[0017]
As shown in FIG. 6, the supply passage portion 22a is provided with a triangular convex portion 46 having a tapered surface 46a of about 40 degrees on the inner wall of the passage, and a concave portion 47 is formed opposite to the convex portion 46. It is provided so that the pachinko balls flow down in a meandering manner. The convex portions 46 are located between pachinko balls continuously stopped by the support portion 29 of the operating body 25, and the height is selected to be approximately equal to or less than the hemisphere of the diameter of the pachinko balls, and the pachinko balls are provided in the supply passage portion 22a. In the state where the ball is continuously stopped, the pachinko ball is stopped almost linearly. As shown in FIG. 6, the pachinko sphere contacting the upstream side of the convex portion 46 and the subsequent pachinko sphere are shifted in the position of the ball center by the step 48 on the side wall provided with the convex portion 46. Yes. Further, as shown in FIG. 5, an inclined flat surface 23a is formed on the inner surface of the outer peripheral wall of the refracting portion 23 with a predetermined dip angle of about 45 degrees, and a vertical surface 23b continues to the lower end of the inclined flat surface 23a. .
[0018]
In the ball payout device 12 of the pachinko machine configured as described above, when the solenoid 27 is excited by a command from the ball payout control device, the support portion 29 of the operating body 25 is opened as shown in FIG. When the pachinko ball is submerged from the hole 37 and is no longer restrained, the pachinko ball is paid out by its own weight to the ball discharge rod 14 through the payout passage 22b, and the ball counting sensor 40 detects the predetermined number of pachinko balls. When the command is issued again from the payout control device and the support portion 29 of the operating body 25 protrudes, the payout of the pachinko balls stops. Then, the pachinko balls paid out to the ball discharge basket 14 are guided to the upper ball tray 5 through the ball outlet path 13.
[0019]
In this ball dispensing device 12, the pachinko balls that flow down through the gently inclined supply passage portion 22a flow down to the concave portion 47 by the tapered surface 46a of the convex portion 46 as shown by the chain line in FIG. Further, the pachinko ball in contact with the upstream side of the convex portion 46 is displaced by the step 48 on the side wall so that the center of the subsequent pachinko ball is displaced toward the concave portion 47, so that the ball pressure toward the concave portion 47 is weakened. Yes. As described above, the flow force can be surely weakened while being compact without being bent into an S shape as in the prior art.
[0020]
Further, the pressure of the pachinko ball that flows down the supply passage portion 22a that is further gently inclined is first applied to the tapered surface 46a of the convex portion 46 and applied to the inclined flat surface 23a and the vertical surface 23b. Since the support portion 29 of the operating body 25 moves in and out along the direction of the substantially extending line of the bottom surface of the supply passage portion 22a, the operating body 25 moves in and out without causing pressure to resist the movement. Do not give a big load to. For this reason, the movement of the operating body 25 can always be made smooth.
[0021]
Further, in this ball dispensing device 12, since the vertical dispensing passage portion 22b is formed at the lower end of the gently inclined supply passage portion 22a via the refracting portion 23 that curves sharply downward, it flows down the supply passage portion 22a. As the pachinko ball collides with the vertical surface 23b and passes through the refracting portion 23, the flow velocity is reduced, so that the optical axis of the ball counting sensor 40 does not exceed a certain velocity and detection errors are unlikely to occur. .
[0022]
In addition, by forming an inclined flat surface 23a that is rolled up at a predetermined depression angle on the inner surface of the outer peripheral wall of the refracting portion 23, the pachinko balls flowing down the supply passage portion 22a collide with the inclined flat surface 23a and are turned downward. As a result, the speed of the pachinko ball is reduced more effectively. For this reason, it is possible to make detection mistakes less likely to occur. If the inner surface of the outer peripheral wall of the refracting portion 23 is formed in an arcuate shape, the pachinko sphere gradually turns while contacting the arcuate surface, so that the sphere speed is not significantly reduced. On the other hand, when the inclined flat surface 23a is formed, the high-speed pachinko sphere collides with the inclined flat surface 23a and rebounds, so that the speed can be greatly reduced.
[0023]
Further, as shown in FIG. 5, since the pachinko sphere supported by the support portion 29 has not been detected by the ball counting sensor 40, even if the pachinko sphere bounces against the support portion 26, the pachinko sphere There is no risk of double detection by the ball counting sensor 40. Further, by arranging the optical axes so as to intersect at a position deviated from the center line of the payout passage portion 22b, even if a large number of pachinko balls run down the ball passage 22 without gaps, no light passes between the pachinko balls. An interval can be passed, and the number of pachinko balls falling can be surely counted.
[0024]
The supply passage portion 22a is not limited to an inclined shape and may be formed in a vertical shape. Further, by providing the unevenness portions 46 and 47 in the payout passage portion 22b, the flow force of the pachinko balls to be paid out can be weakened, and damage and wear of the bell 18 of the ball discharge rod 14 and the ball lead-out passage 13 can be prevented. Further, in the above embodiment, the ball dispensing device 12 has been described as using the solenoid 27 as an electric drive source. However, the present invention is not limited to this, and all the ball dispensing devices including the ball stopping means 21 are used. Is also applicable.
[0025]
【The invention's effect】
As described above, it is clear from the above description that the ball payout device for the pachinko machine according to the present invention is compact, and the ball pressure applied to the ball stopping means is greatly reduced by forming the uneven portion in the ball passage. There is an advantage that stable operation is realized and the pachinko balls can be reliably delivered. In addition, by providing an uneven portion in the payout passage portion, it is possible to weaken the flow of the pachinko balls to be paid out and prevent damage and wear of the ball discharge rod and the ball lead-out path.
