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 for guiding 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 path of the transfer rod. For example, when a failure such as a ball biting occurs in the pachinko ball payout 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 path of the transfer rod is two, for example, the pachinko balls in each ball path are discharged one by one while moving at a predetermined pitch (for example, the radius of the pachinko ball) as the sprocket or lead screw rotates. Therefore, depending on the number of pachinko balls to be paid out, the stop positions of the pachinko balls in the two rows of ball paths are shifted by the radius of the pachinko balls.
[0005]
However, in the case where the ball stop position by the ball stop piece is always determined as in the conventional ball stop member, depending on the stop position of the pachinko ball, the ball stop piece may hit the pachinko ball in the ball passage and stop the ball. There was a problem that it was not possible.
[0006]
The present invention has been made in view of the above-described problems, and the object of the present invention is when pachinko balls in two rows of ball paths are stopped in a state where they are alternately shifted from each other by a predetermined pitch.
