2. Description of the Related Art As a ball game machine, for example, a pachinko game machine using a pachinko ball is known. In a pachinko gaming machine, when a pachinko ball hit in a game area covered with a glass plate enters a winning opening, a predetermined number of pachinko balls are released as prize balls. These prize balls are first discharged to the hitting ball supply plate, and when the hitting ball supply plate is full, the pachinko balls overflowing from the hitting ball supply plate fall to the storage plate portion arranged below.

The pachinko balls in the storage tray are extracted into a box for transportation through a ball-punching hole provided in the bottom wall thereof. At that time, the opening / closing plate provided in the ball punching hole is moved by hand, but the opening / closing plate is biased by a spring, and the ball punching hole is closed when the hand is released. Therefore,
When the surplus balls continuously drop, it was necessary to frequently move the opening and closing plate, which was troublesome.

Therefore, there is a ball-punching device which can hold the ball-punching hole open even when the hand is released from the opening / closing plate.
9571 publication. This ball punching device is provided with a groove hole communicating with the ball punching hole on the bottom wall of a storage bowl for pachinko balls, and a shutter plate for opening and closing the ball punching hole is fitted with the groove hole at the first position where the ball punching hole is fully opened. By the way, the 1st concave part which one pachinko ball falls in is provided. The shutter plate is biased by a spring in the direction of closing the ball punching hole.

Further, the shutter plate is provided with a second concave recess portion which is continuous with the first concave recess portion via a low damming portion. The second recessed portion coincides with the groove hole at the second position where the shutter plate substantially fully opens the beading hole. Further, the shutter plate is provided with a concave groove portion which communicates with the second concave portion and guides the pachinko ball of the second concave portion to the ball-punching hole. The groove on the bottom wall is inclined in a direction in which the shutter plate moves so as to close the shutter hole from a position coinciding with the second recess, and the groove on the shutter plate is opposite to the groove on the bottom wall. Inclined in the direction.

In the above-mentioned punching device, the shutter plate is usually placed at a position where the punching hole is closed by a spring.
In this state, put your finger on the operation part of the shutter plate to move the shutter plate to the first position where the ball punch hole is fully opened.
The slot on the bottom wall and the first concave portion of the shutter plate coincide with each other, and one pachinko ball of the storage dish falls into the first concave portion. When the hand is released from the operation section in this state, the shutter plate moves back in the direction to close the ball punching hole by the elasticity of the spring, and the pachinko ball crosses the damming section from the first concave section and enters the second concave section. .

Even if the operator releases his or her hand from the operating portion in this state, the movement of the shutter plate in the closing direction exerts a force in the direction opposite to the punching hole direction on the pachinko ball due to the inclination of the concave groove portion, so that the pachinko ball moves to the first position. 2 Stops in the recessed portion, contacts the edge of the groove hole, and holds the shutter plate in the second position where the ball hole is substantially fully opened. To return the shutter plate to its original position, place your finger on the operation part and move it to the position where the shutter plate is fully opened, and the slanting groove of the shutter plate causes the pachinko ball to move in the slot and be guided to the ball drop hole.
