DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball punching device for a ball tray in a ball game machine such as a pachinko machine and an arrangement ball machine.

[0002]

2. Description of the Related Art In a ball-and-ball game machine such as a pachinko machine, when a game ball fired along a guide rail enters a prize port of a game board or other prize-winning means and receives a prize, the ball is paid out according to the prize-winning conditions at that time. When the means is activated and a predetermined number of game balls are paid out to the upper ball tray, and when the upper ball tray becomes full,
The game balls from the ball payout means overflow to the lower ball tray.

[0003] The game balls in the lower ball tray can be removed at any time by a ball removal device. Conventionally, this ball punching device has a ball punching hole formed at the bottom of the lower ball tray, an opening / closing plate for opening and closing the ball punching hole, a ball punching lever integrated with the opening / closing plate, and a closing / closing plate in the closing direction. A biasing spring is provided, and when the ball release lever is operated in the opening direction against the spring, the opening / closing plate slides in the opening direction to open a ball removal hole, and from the ball removal hole into the lower ball receiving tray. Game balls are to be removed.

[0004]

The game balls in the lower ball tray need to be removed not only when the game balls remain at the end of the game but also during a game such as a big hit. . That is, when a big hit etc. occurs,
Since a large number of game balls are successively paid out from the ball payout means, the upper ball tray becomes full immediately and the game balls overflow to the lower ball tray, but if the lower ball tray becomes full,
A full detection switch is activated to stop the firing means. Therefore, in the case of a jackpot or the like, it is necessary to extract the game balls in the lower ball tray so as not to be full.

However, in the conventional ball-pulling device, when the ball-pulling lever is operated in the opening direction, the opening / closing plate slides in the opening direction against the spring to open the ball-pulling hole, and the ball-pulling lever is opened. When the operating force is released, the opening / closing plate is pushed back by the spring to close the ball removal hole, so during the removal of the game ball, the ball removal lever must always be operated in the opening direction. However, there is a disadvantage that the operation is very troublesome.

In particular, in the case of a jackpot, the ball must be manipulated with the right hand and the ball release lever must be operated with the other left hand while continuing the game, so that it is difficult to operate the ball release lever at the same time. However, there is a drawback that the player cannot worry about the operation of the ball release lever and cannot concentrate on the game. The present invention has been made in view of the above-described conventional problems, and can easily hold the opening / closing plate at the open / close position only by operating the ball pulling lever in the opening / closing direction, and easily pull out the game ball from the ball tray with a simple operation of the ball pulling lever.
