Description

[Detailed description of the invention] This invention is a game that automatically stops the game by blocking the supply port that supplies the ball to the ball launch position when the tank that stores the prize balls runs out of prize balls. This invention relates to improvement of the interlocking rod of the stopping device.

As is conventionally known, the game stopping device is equipped with a freely swinging detection plate that is constantly biased in the upward direction by the action of a weight at the bottom of the ball supply gutter connected to the storage tank, and the other side fires the ball. The supply port for supplying to the position is equipped with a gate plate that swings around a support shaft, and an interlocking rod connects the two parts arranged separately at the upper and lower parts of this pachinko machine, and the gate plate is connected to the storage tank. When the prize balls are full and the balls are on the detection plate, the gate plate is opened via the interlocking rod to enable the supply of balls, and when the prize balls are insufficient and the balls disappear from the detection plate. When the ball is released from the ball pressure, the detection plate is lifted up by the action of a weight, and the gate plate is accordingly closed to stop the supply of balls and automatically stop the game. It's summery.

By the way, the detection plate in the above-mentioned conventional device is equipped with a weight on the opposite side across the support shaft and is lifted up, and an interlocking rod is connected to the swinging end of this jumping up to pull up the gate plate connected to the lower end. In this state, the ball supply port was closed, and the interlocking rod itself was made of wire.The interlocking rod itself was made of wire. In order to accurately transmit the movement of the detection plate to the gate plate, this wire interlocking rod has a connecting part in the middle of its length that can be freely changed in length by tightening screws.
By adjusting this, manufacturing errors can be absorbed and the length can be adjusted to an appropriate length.

However, since conventional interlocking rods are made of wire and have the length necessary to connect distant parts, they can flex, resulting in subtle changes in length between the detection plate and the gate plate. There was a problem that caused the operation to go awry. In addition, in the conventional device, a weight was attached to the detection plate, and the action of this weight was used to bias it in the upward direction, but in addition to the complexity of the structure, there was a risk of malfunction, so improvements are desired. was.

This invention was devised in view of these points,
The main connecting rod, which is the main body of the interlocking rod, is made of a metal band plate to give it the required weight.This eliminates the weight, eliminates deflection, and always maintains a constant length. To provide an interlocking rod for a game stopping device that can accurately transmit a certain motion depending on the distance between the two.
