Abstract

PROBLEM TO BE SOLVED: To improve quality reliability and a game property. SOLUTION: A contact section 20 with a ball 120 of one projection 19 and a contact section 20 with the ball 120 of another projection 19 adjoining in the peripheral direction are formed alternately in the width direction of a sprocket. Each time when the projection 19 first meets the ball 120, the contact is made at a position alternately drifted in the width direction from the face center of gravity position of the ball 120, thereby the ball 120 is vibrated in the width direction each time when it first meets the projection 19 of the sprocket, and the ball biting at this portion is prevented.

In the above-mentioned conventional example, one notch 112a, which extends from the outside of the passage case 102 to the inside of the ball passage 101 via the opening 104 with the rotation of the sprocket 110, is located rearward in the rotational direction. The convex part 113 located
a protrudes into the ball passage 101 from the opening 104, and in the process where the distance between the protrusion 113 a and the constriction 103 becomes smaller than the diameter of one ball 120, the ball 120 to be taken into the one notch 112 a May not be taken into the notch 112a for some reason. In this case, the one ball 120 tends to go downward by the weight received from all the balls existing above itself, but the distance between the constricted portion 103 and the convex portion 113a is smaller than the diameter of the ball 120. One ball 12 according to the timing at which
There is a possibility that a ball biting between 0 is sandwiched between the constricted portion 103 and the convex portion 113a. When such a ball bite occurs,
It becomes impossible to regularly pay out the balls 120 one by one from the sprocket 111, which impairs the quality reliability of the prize ball payout and also impairs the game performance. The notch 112 a is the same as the notch 112, and the notch 112 a
Since a is also the same as the convex portion 113, the notch portion should be denoted by reference numeral 112 and the convex portion should be denoted by reference numeral 113, but in the description of the problem, it is specified which cutout portion and the convex portion are indicated. For this purpose, a notch 112a and a convex 113a were used.

According to the present invention, a part of the periphery of a sprocket having notches and projections alternately in the circumferential direction is projected into a ball passage for guiding a ball from above to below. In addition, in the ball dispensing device that rotatably supports the sprocket with respect to the ball passage, the sprocket rotates the contact portion between the one protruding ball and the other protruding ball adjacent in the circumferential direction. It is characterized by being formed alternately in the width direction which is the same direction as the axial direction. Therefore, according to the present invention, each time the convex portion first encounters the sprocket, the convex portion contacts the convex portion of the sprocket by contacting the ball at a position that is alternately shifted in the width direction from the center of gravity of the surface of the ball for each scene. Therefore, it is possible to prevent the ball from vibrating in the width direction at that portion.

In FIG. 4, even if the sprocket 16 slides to the left in the same direction as the axial direction, one ball 120 contacts the contact portion 20 having the left slope 22 so that the ball 120 is It is in the form of standing on a precipitous cliff at the boundary of 20, and there is no receiver on the left side of the ball 120 and a receiver on the right side of the ball 120. In this state, the sphere tilts to the left, and as a reaction of the sphere, the sprocket 16 slides to the right, and as shown in the drawing, the contact portion 20 moves downward with the flowing line passing through the center of gravity of the sphere 120 and the sphere 120. The ball 120 comes into contact with the ball 120 at a position shifted to the right more than the center of gravity of the surface, which is an intersection with the outer peripheral surface. Due to this misalignment contact, the ball 120 is reliably driven to the left in the ball passage 11, contacts the wall surface of the first case 2, and slides the sprocket 16 to the right. That is, the ball 120 is attached to the sprocket 16
3 comes into contact with the one contact portion 20, the wall surface of the first case 2, and the partition wall 15 in FIG.

In the state shown in FIG. 3, the sprocket 16 is rotated in the W direction by the weight of a ball (not shown) taken into the notch 18 of the sprocket 16 in the ball passage 11, and is shown by a virtual line in FIG. The notch 18 following the protrusion 19 in contact with the ball 120 in the rotation direction W is the ball passage 1.
As the ball 1 enters the sphere 1, the sphere 120 shown in FIG. 4 corresponding to the sphere 120 shown by the phantom line in FIG. Thereafter, the rotation of the sprocket 16 progresses, and the projection 19 following the rotation direction W from the notch 18 into which the sphere 120 is taken out projects into the sphere passage 11 and the sphere 12 indicated by an imaginary line.
The ball outside the figure following 0 is received. This state is shown in FIG.
