[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ball payout device in a pachinko gaming machine that pays out a pachinko ball to a payout passage by rotating a payout rotor.
[0002]
[Prior art]
A disk-shaped payout rotor having a ball receiving hole in which a pachinko ball can be loosely fitted on the outer peripheral surface is rotatably driven in a vertical plane by a motor, and the rotational speed of the payout rotor is controlled as a prize. A pachinko ball dispensing apparatus configured to dispense a predetermined number of pachinko balls is well known.
[0003]
By the way, since the payout of pachinko balls as a prize is often concentrated at a time, it is necessary to rotate the payout rotor at a high speed so that a large number of pachinko balls can be paid out in a short time.
[0004]
However, if the payout rotor is rotated at a high speed, the payout rotor will rotate immediately before the pachinko ball loosely fits in the ball receiving hole on the outer periphery of the payout rotor, which may cause ball engagement and ball clogging. Met. In addition, if the depth of the ball receiving hole is made shallow to avoid this, the pachinko ball will bounce in the hole and vibrate vigorously and easily come off from the hole, which also causes the ball biting and clogging. .
[0005]
Further, the ball dispensing device is provided with a sensor for counting the pachinko balls to be paid out. However, if the movement of the pachinko balls is unstable as described above, it may cause a detection error by such a sensor. there were.
[0006]
[Problems to be solved by the invention]
The present invention eliminates the above drawbacks and improves the shape of the payout rotor so that the payout operation is always performed smoothly even when the payout rotor rotates at high speed, so that the pachinko ball can be discharged at high speed without clogging the ball. It is to make.
[0007]
[Means for Solving the Problems]
For this purpose, the ball payout device for a pachinko gaming machine according to the present invention forms a V-shaped ball receiving hole on the outer peripheral surface of a payout rotor provided to be rotated in a vertical plane by a motor, and the ball receiving hole. And the pachinko ball is set to a substantial hole depth of the ball receiving hole so that the pachinko ball is supported at two points on the inner surface of the hole when the pachinko ball is loosely fitted to ¼ to ３ of its diameter. To do.

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. In the ball payout device shown in this embodiment, the pachinko balls are paid out to the rental ball payout passage or the prize ball payout passage by rotating the payout rotor forward or backward. Further, in this embodiment, a pair of payout rotors are provided so that pachinko balls are allowed to flow in two rows from a prize ball tank provided on the back of the gaming machine main body, and are discharged in two rows.
[0009]
In the figure, 1 is a plastic case, 2a and 2b are drop holes for dropping pachinko balls p formed in the case and flowing down from a prize ball tank into the case, and 3a and 3b are vertical surfaces directly below the drop opening. A disc-shaped payout rotor provided to rotate in the inside, 4 is a pulse motor which is provided on one outer side of the case 1 so as to be able to rotate forward and reverse, and 5 and 6 are the motors. 4 is a pinion and a gear that transmit the rotation of 4 to the rotating shaft 7 of the payout rotors 3a and 3b. On both sides of the payout rotors 3 a and 3 b, the ball passage is bifurcated. One is a rental ball payout passage 8 and the other is a prize ball payout passage 9.
[0010]
The payout rotors 3a and 3b are formed with two ball receiving holes 10 on the outer peripheral surface at intervals of 180 degrees. The payout rotor 3a and the payout rotor 3b are fixed to the rotary shaft 7 with a phase difference of 90 degrees from each other, and the pachinko ball p is moved into the rental payout passage 8 or It is distributed to the prize ball payout passage 9. Reference numerals 11 and 12 denote sensors provided at both branch portions in order to detect pachinko balls paid out to the lending ball payout passage 8 or the prize ball payout passage 9.
[0011]
1 to 4 , the payout rotors 3a and 3b are such that the hole depth d of the ball receiving hole 10 formed on the outer peripheral surface is substantially in the range of 1/4 to 1/3 of the diameter of the pachinko ball p. I have to. That is, the pachinko ball p is transferred by the rotation of the payout rotor in a state in which 1/4 to 1/3 of the diameter of the pachinko ball p is loosely fitted in the ball receiving hole 10. In other words, 3/4 to 2/3 of the diameter of the pachinko ball p sets the width of the payout passage 8 or the payout passage 9 so that the payout rotor can rotate while protruding from the outer peripheral surface of the payout rotor. Since the diameter of the pachinko sphere p is generally 11 mm to 11.5 mm, the hole depth d is in the range of 2.75 mm to 3.83 mm. If the hole depth d is shallower than this, the pachinko ball that collides with the bottom of the hole and bounces hits the next inner pachinko ball or the lower inner edge of the drop openings 2a, 2b to vibrate and make a loud sound, making it difficult to increase the speed . Further, when the hole depth d is deeper than this, if the speed increases, the fall of the pachinko ball p is not in time, and the payout rotor rotates even before the pachinko ball p is completely loosely fitted in the ball receiving hole 10. As a result, the width of the payout passage 8 or the payout passage 9 must be set sufficiently, and this also causes ball engagement when the consistency with the speed is poor. Therefore, in the present invention, by setting the substantial hole depth d within such a range, the rotational speed and the dispensing speed can be increased, and the pachinko balls can be smoothly moved at a wide speed from a low speed to a high speed. The ball can be moved stably and can be dispensed stably without clogging.
[0012]
FIGS. 5 and 6 show the embodiment of the present invention as set forth in claim 1. The ball receiving hole 10 formed on the outer peripheral surface of the payout rotors 3 a and 3 b has a loosely fitted pachinko ball p on the inner surface of the hole. The ball receiving hole 10 is V-shaped so that it can be supported at two points t1 and t2. Thus, the pachinko ball can be stably supported in the ball receiving hole 10 by allowing the pachinko ball loosely fitted in the form of the ball receiving hole 10 to be brought into contact with the ball receiving hole 10. Since the pachinko balls p that have fallen into 10 first collide with either of the V-shaped slopes of the ball receiving hole 10, the direction in which the pachinko balls bounce can be dispersed laterally. For this reason, the impact caused by the collision with the next falling pachinko ball is alleviated, so that the high-speed payout can be performed smoothly.
In this embodiment, the disk-shaped payout rotor has been described. However, the present invention can be applied to other forms such as a lead screw.
[0013]
【The invention's effect】
As described above, the ball payout device for the pachinko gaming machine according to the present invention has a hole depth substantially equal to 1 / diameter of the diameter of the pachinko ball on the outer peripheral surface of the payout rotor provided to be rotationally driven in the vertical plane by the motor. Since the ball receiving hole of 4 to 1/3 is formed, the dispensing operation is always performed smoothly even if the dispensing rotor is rotated at high speed, so that the pachinko balls can be dispensed at high speed without clogging the balls. Has a beneficial effect.
