Description

[Detailed explanation of the invention] [Field of industrial application] This invention prevents the ejection of winning balls from the machine when the prize balls in the prize ball tank run out, and at the same time stops the supply of balls to play the game. This is about a pachinko machine that was designed to avoid this problem.

[Conventional technology]

Conventionally, when there is a shortage of prize balls in the prize ball tank, a flow prevention piece is inserted into the prize ball discharge passage to prevent the winning balls from flowing down, thereby preventing the prize balls from being paid out. A pachinko machine configured as described above is known (see, for example, Japanese Utility Model Publication No. 18042/1973).

[The problem that the idea aims to solve]

With conventional pachinko machines, the game can continue even when the prize balls are not paid out due to a shortage of prize balls in the prize ball tank. There is a lot of risk that it will accumulate in the body and cause a ball-biting phenomenon.
Then, when such ball jamming occurs, there is a problem in that the prize balls cannot be paid out unless the winning balls are removed from the winning ball collecting section. And in order to remove the winning balls,
After removing the various electrical wiring on the back of the game board, it is necessary to open the mechanism board on which the back parts such as the prize ball tank and prize ball release device are assembled, and this work is tedious and extremely time-consuming. Ta.

This invention prevents the payout operation of prize balls when there is a shortage of prize balls in the prize tank, and at the same time blocks the supply of balls to stop the game. The object is to provide a pachinko machine that can reliably prevent the biting phenomenon.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a mechanism plate on the back of the game board, a prize ball tank above the mechanism plate, and a prize ball tank at the bottom of the guide gutter communicating with the prize ball tank. A detection plate is installed that rotates upward when the prize balls in the tank break.
A pachinko machine in which a winning ball collecting section is provided at approximately the center of the mechanism board, and rear parts such as a prize ball discharging device and a winning ball discharging device are collectively provided on one side of the winning ball collecting section. , a vertical rod is arranged on the side opposite to the side of the mechanism plate where the back part is provided, and on the outside of the side of the winning ball collecting part, and on the lower side of the winning ball collecting part. A blocking rod is disposed on the outside, and the upper end of the vertical rod is connected to the detection plate via a link, and the lower end is pivotally connected to the rotating plate, and the tip of the blocking rod is connected to the winning ball. It faces the exit of the collection part so that it can move forward and backward, and its rear end is pivotally connected to the rotating plate via a link and a connecting rod. It is connected to an opening/closing lever that opens and closes the ball supply opening of the ball supply tray.

[Effect]

When there is a shortage of prize balls in the prize ball tank, the detection plate rotates upward, and the rotating plate rotates via the link and vertical rod connected thereto. By the rotation of this rotating plate, the tip of the shielding rod enters the exit of the winning ball collecting section through the link and the connecting rod, preventing the winning balls from flowing down to the winning ball processing device, and at the same time, the opening/closing lever is activated. It moves laterally via a link mechanism, closes the ball supply port, and brings the game to a halt state where ball launch is impossible.
