Description

[Detailed description of the invention] The present invention is designed to stop the supply of shot balls by blocking the inlet of the ball supply device that sends the shot balls to the firing position when the storage tank runs out of prize balls. This invention relates to a game stop device for a pachinko machine that automatically stops the game when the game is stopped.

As is well known, pachinko machines are designed to eject a predetermined number of prize balls when the balls fly into the prize opening of the game board. Normally, the prize balls are stored in a storage tank provided on the back side of the base plate of the pachinko machine, and guided to the prize ball device through a ball supply gutter connected to this storage tank. When a winning ball (safe ball) flies in, the prize ball device is opened in response to a command from the safe ball detector that detects this, and the ball is released to the player as a prize ball. However, if the game continues with a shortage of prize balls in the storage tank, the prize balls may not be released even though the prize ball device is operating normally, or the number of prize balls may not be reached. In some cases, a ball that is not present may be ejected.

The present invention detects when there is a shortage of prize balls stored in such a storage tank and blocks the entrance of the automatic ball supply device to stop the supply of shot balls, thereby automatically starting the game. To provide a game stopping device which prevents the game from being released as described above.

Board 9
As mentioned above, if there is a ball, the shutter piece will be opened regardless of the spring force.

As explained above, when there is a prize ball in the storage tank, the device of the present invention moves the operating plate 11, the interlocking rod 12, the swinging member 13, the rotating member 14, and the like by lowering the detection plate 9. The shutter piece 16 of the gate plate opens via the interlocking member 15, and when there are no more balls, the shutter piece automatically closes the ball supply port 29 and hits the ball when the detection plate 9 jumps up. Since the sending of balls to the supply device is stopped, the prize ball device will not operate with insufficient prize balls.

In this way, the device of the present invention prevents the release of missing prize balls, and as mentioned above, the detection plate 9 has its swing fulcrum placed on the left end of the board, that is, on the upstream side, and the other end facing downstream is moved up and down. At the same time, an operating plate 11 is provided in parallel below this detection plate, and the interlocking rod 1
