Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ball stop structure for a transfer rod that guides a pachinko ball in a ball tank to a pachinko ball dispensing device.
[0002]
[Prior art]
Conventionally, a mechanism plate made of synthetic resin is mounted on the back of the game board of the pachinko machine, and a ball tank is fixed to the upper portion of the mechanism plate. In addition, a transfer rod that guides the pachinko balls stored in the ball tank to the pachinko ball dispensing device is provided below the ball tank, and the ball stop member can be rotated on the horizontal axis that is passed over the transfer rod. Provided.
[0003]
The ball stop member is integrally provided with a ball stop piece corresponding to the ball passage of the transfer rod. For example, when a failure such as ball biting occurs in the pachinko ball dispensing device, it is necessary to repair it. The ball stop member is rotated to the ball stop position so that the ball stop piece enters each ball passage of the transfer rod, thereby preventing the pachinko ball from flowing down.
[0004]
[Problems to be solved by the invention]
By the way, in the pachinko ball dispensing device used in recent pachinko machines, a sprocket in which a plurality of concave ball receiving portions for receiving the pachinko ball are formed on the outer periphery or a protrusion that supports the pachinko ball on the outer periphery is formed in a spiral shape. By rotating the lead screw with a motor, the pachinko balls in the ball passage of the transfer rod are discharged one by one. That is, when the ball paths of the transfer rod are, for example, two rows, the pachinko balls in each ball path are discharged one by one while moving alternately by a predetermined pitch (for example, the radius of the pachinko ball) as the sprocket or lead screw rotates. Therefore, the stop positions of the pachinko balls in the two rows of ball paths are shifted alternately from left to right depending on the number of pachinko balls to be dispensed.
[0005]
However, in the case where the ball stop position by the ball stop piece is always determined like the conventional ball stop member, depending on the stop position of the pachinko ball, the ball stop piece hits the pachinko ball in the ball passage and stops the ball. There was a problem that could not.
[0006]
The present invention has been made in view of the above-described problems, and the object thereof is a case where pachinko balls in two rows of ball passages are stopped in a state where they are alternately shifted from each other by a predetermined pitch. It is an object of the present invention to provide a ball stop structure for a transfer rod in a pachinko machine that can reliably stop the ball.
[0007]
[Means for Solving the Problems]
In order to achieve the above-described object, the ball stop structure of the transfer rod in the pachinko machine of the present invention has two ball passages, and the ball stop on the transfer rod that guides the pachinko ball of the ball tank to the pachinko ball discharge device. In the pachinko machine comprising the members, the ball stop member is integrally provided with two ball stop pieces that respectively enter the two ball passages of the transfer rod at the front end portion to prevent the pachinko ball from flowing down. At the same time, the rear end portion is swingable in the left-right direction and pivotally attached to the ball stop position and the ball stop release position.
[0008]
The transfer rod is constituted by two members, a tank rail portion that aligns and guides pachinko balls of a ball tank and a curve rail portion that leads to a pachinko ball dispensing device while reducing the ball pressure of the tank rail portion. It is preferable to provide a ball stop member at the portion.
[0009]
Further, the ball stop member is provided with a cylindrical portion having a shaft through hole at a rear end portion thereof, and the shaft through hole of the tube portion is loosely inserted into a horizontal axis passing to the curve rail portion to fix the ball stop member to the ball. It is preferable to pivot between the position and the ball stopper release position, and to pivot so that the shaft through hole of the cylindrical portion has a larger diameter than the horizontal axis and can swing in the left-right direction.
[0010]
Further, a long groove hole is provided at the rear end portion of the ball stop member, an annular hook piece is provided at the curve rail portion, and the long groove hole of the ball stop member is engaged with the annular hook piece, whereby the ball stop member is It may be pivotable to a stop position and a ball stop release position, and pivotably pivotable in the left-right direction.
[0011]
Further, in order to lock and hold the ball stop member at the ball stop release position, an engagement hole is provided in the ball stop member, and the curve rail portion is engaged with the engagement hole at the ball stop release position of the ball stop member. It is preferable to provide joint protrusions.
[0012]
The ball stop structure of the transfer rod in the pachinko machine configured as described above can freely swing the ball stop member in the left-right direction with respect to the flow-down direction of the pachinko ball. Even if the pachinko ball stop position is shifted alternately left and right by a predetermined pitch, the ball stop piece can be plunged into the ball passage in accordance with the pachinko ball stop position, which ensures that the pachinko ball flowing down the transport rod It is possible to stop the ball.
