On the front wall of a shallow box-shaped case incorporating the opening / closing plate, a rail portion for regulating the movement amount of the opening / closing plate is formed, and the first and second locking grooves are provided in the rail portion, and the locking groove is opened and closed. A protrusion on the back surface of the plate is detachably engaged from above to hold the opening / closing plate at the open position of the ball hole, or Japanese Patent Publication No. 3-539.
As disclosed in Japanese Patent Application Publication No. 54-54, a locking member is provided in a support frame fixed to the lower surface of a ball tray so as to restrain the sliding body from moving at a position where the sliding body opens a ball hole. There is a device provided with a pressing member for releasing the restraint of the locking member and returning the sliding body to a position for closing the ball hole.

[0003]

However, in the former ball punching device, since the projection of the ball punching device only fits into the locking groove from above due to the weight of the opening / closing plate, the opening / closing plate floats due to an impact at the time of ball pulling out. There was an erroneous operation in which the stop came off and the sliding plate closed the ball hole during the ball hole removal. Also, in the latter ball removing device, the locking member automatically enters by the spring and prevents the sliding body from moving on its side, so that the malfunction does not occur as in the former, but the restraint of the locking member is released. For this reason, the number of components as a whole is increased, such as providing a pressing member on the sliding body, and therefore, there has been a problem that the production of the ball removing device becomes complicated and also the production cost increases.

Accordingly, the present invention has been made to solve the above-mentioned problem, and has a simple structure, is easy to manufacture, and has no malfunction such as a shutter plate closing a hole for removing a ball while removing the ball. It is an object of the present invention to provide an apparatus for removing a ball from a ball storage dish.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above objects, the present invention provides a dish body capable of storing pachinko balls, a ball hole for extracting pachinko balls stored in the dish body, and a bottom surface of the dish body. A shallow box-shaped frame plate that is mounted and the top surface of which is open, and is housed in a sliding space formed between the bottom of the dish main body and the frame plate, and is biased to a position where the ball hole is closed by a spring. A shutter plate that opens a hole for removing a ball by sliding in the horizontal direction, and an operating member that slides the shutter plate, a moving amount of the shutter plate on a front side wall of the frame plate. And a notch at one end of the rail, and an insertion groove into which the rail is fitted on the back side of the shutter plate, and one inner surface from one position of the insertion groove. And the other inside surface Forming a tapered surface expanding toward the side end, at the end of one of the tapered surfaces, the shutter plate is tilted horizontally so that the tapered surface abuts on the front side wall at a position where the ball hole is opened, and the cutout portion is formed. And a locking projection that can be engaged with and disengageable from the vehicle.

[0006]

In a normal state, the ball hole is closed by the shutter plate by the force of the spring. Therefore, when removing the ball, the shutter plate is moved to a position where the ball removing hole is opened against the force of the spring. When the shutter plate comes to this position, the locking protrusion at one end of the insertion groove is disengaged from the front side wall of the rail portion and is tilted horizontally so that the tapered surface contacts the front side wall, and the locking protrusion engages with the notch. Combine. As a result, the shutter plate is held in a state where the ball hole is opened even when the hand is released from the operation member. In this state, the locking projection is firmly engaged with the notch by the force of the spring. On the other hand, if the operating member on the side opposite to the locking projection is pushed forward in this state, the shutter plate tilts and returns to the original position, and the locking projection is released from the cutout. Then, the shutter plate moves by the force of the spring and returns to the original position, and closes the ball hole.
