DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball rectifying device for a pachinko machine in which a pachinko ball path supplied from a storage tank is rectified from two rows to one row and rectified and sent to a pachinko ball dispensing apparatus.

[0002]

2. Description of the Related Art Conventionally, a pachinko ball dispensing apparatus of a pachinko machine counts pachinko balls one by one, so that a fixed number of pachinko balls to be paid out for each winning ball can be set, changed and adjusted. To such a pachinko ball dispensing device, the pachinko balls of each row of the guiding gutter rectified in two rows from the ball tank are controlled one by one alternately and sent out in one row. I have.

As the above mechanism, for example, Japanese Patent Publication No. 5-551
There is one disclosed in Japanese Patent Application Publication No. 5 (JP-A-5). In the mechanism, a disk-shaped rotary body having several arcuate surfaces and concave recesses into which pachinko balls can be fitted at equal intervals is installed on the outer periphery, one for each two rows of ball passages, and these rotary bodies are provided. Pachinko balls in each row are arranged one by one by displacing a half pitch for one arc surface in the rotation direction in parallel with each other and rotating each rotating body by receiving a ball pressure from above. It takes in alternately with a predetermined timing difference and sends it out. In addition, as disclosed in Japanese Patent Application Laid-Open No. 61-76181, for example, there is a type in which two rotating bodies are rotationally driven by a power unit including a gun wheel and an anchor member operated by an electromagnet.

In the mechanism described above, in the case of the former, two rotating bodies which are individually installed in two rows of spherical passages are required, and these two rotating bodies are arc-shaped surfaces of the rotating bodies. In order for the recesses and depressions to face the ball passages of each row in a staggered manner, they must be installed with a predetermined pitch difference, and the disc-shaped rotating body is located at the center of the pachinko ball passing through each ball passage. Since it must be installed at a certain position, the number of parts is large, and assembly is also difficult to require accuracy.

In the latter case, since the rotating body is driven by the gun wheel and the anchor member, not only the number of parts is increased but also the structure becomes complicated, and the space for installing the electromagnet and the anchor member is secured. And difficult assembly work has been forced. As a result, production efficiency was poor and economic efficiency was not good. In contrast,
It is also conceivable to mount a rotating body having a width that is equal to the width of the two ball passages perpendicular to the two rows of the ball passages.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the molding of the rotating body is easy, the structure is simplified with a small number of parts, and the assembling work is easy. It is an object of the present invention to provide a pachinko ball rectifying device which can be easily stored and installed even in a narrow installation space.

[0007]

In order to achieve the above object, a pachinko ball rectifying device for a pachinko machine according to the present invention comprises:
Two rows of ball paths located on the upstream side, a ball approach guide path for changing and guiding these two rows of ball paths to one row, and a ball approach guide parallel to the two rows of ball paths from the outer side of one ball path. A rotatable rectifying rotator, which faces the road and alternately has a plurality of ball-feeding arms and ball receiving portions into which pachinko balls can be fitted on its outer periphery, and is regulated by the rotator and the ball-advancing guide path. And a single row of downstream delivery paths for delivering pachinko balls one by one.

The ball feed arm has a claw on the side of the tip of the arm in the rotation direction, which intervenes between the pachinko ball received by the ball receiving portion and the pachinko ball riding thereon to smoothly separate both pachinko balls. It is preferable to provide a ball-shaped truncated point.

When the pachinko balls in the two ball paths reach the ball approach guide path, first, the pachinko balls in one ball path enter between the distal end surface of the ball feed arm and the inner surface of the ball approach guide path, and are continuously connected. The ball is moved downward while pushing down the ball feed arm due to the ball pressure of the pachinko ball, and the pachinko ball above it also flows into the ball approach guide path. At the same time, the pachinko ball in the other ball passage fits into the ball receiving portion, is carried downward with the rotation of the rotating body, and intercepts and descends between the pachinko balls from one ball passage. In this manner, the flow is regulated and rectified into one line in sequence and sent out from the sending path.
