However, since the former ball removal device only fits the projection into the locking groove from above due to the weight of the opening / closing plate, the opening / closing plate is lifted by the impact of the ball removal, etc., and the locking is released. There was a malfunction that the sliding plate closed the ball hole. In the latter ball removal device, the locking member automatically enters by a spring and prevents the sliding body from moving on its side, so that the malfunction does not occur as in the former, but the locking member is released. For this reason, the number of parts as a whole is increased, for example, a pressing member is provided on the sliding body, which makes it difficult to manufacture the ball removing device and increases the manufacturing cost.
[0004]
Therefore, the present invention has been made to solve the above-mentioned problems. The structure is simplified, the manufacture is easy, and there is no malfunction such as the shutter plate closing the hole for removing the ball in the middle of the ball removal. The object is to provide a dish bowler.

[Means for Solving the Problems]
In order to achieve this object, the present invention provides a dish body that can store pachinko balls, a hole for extracting the pachinko balls stored in the dish body, a shallow hole that is attached to the bottom rear surface of the dish body and has an open upper surface. It is housed in a sliding space formed between the box-shaped frame plate and the bottom of the plate body and the frame plate, and is urged to close the ball hole by a spring and slides in the lateral direction. In a ball removal device comprising a shutter plate that opens a ball removal hole and an operation member that slides the shutter plate,
Forming a rail portion that regulates the amount of movement of the shutter plate on the front side wall of the frame plate, providing a notch portion at one end of the rail portion, and providing a fitting insertion groove into which the rail portion is fitted on the back side of the shutter plate; A tapered surface is formed on one inner surface and the other inner surface from one portion of the fitting insertion groove so as to extend toward the left and right outer ends, and a shutter plate has a ball hole at the end of one tapered surface. In the open position, the taper surface is tilted horizontally so as to abut against the front side wall, and is provided with a locking protrusion that can be detachably engaged with the notch.
[0006]
[Action]
Normally, 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 hole is opened against the force of the spring. When the shutter plate is in this position, the locking protrusion on one end of the insertion groove is released from the front side wall of the rail part and tilts horizontally so that the tapered surface abuts the front side wall, and the locking protrusion engages with the notch. Match. Thereby, even if the hand is released from the operation member, the shutter plate is held in a state where the ball hole is opened. Further, in this state, since the locking projection piece is firmly engaged with the notch portion by the force of the spring, it does not come off even if it receives an impact at the time of ball removal. On the other hand, when the operation member on the opposite side to the locking projection piece is pushed in this state, the shutter plate is tilted to return to the original position, and the locking projection piece is detached from the notch portion. Then, the shutter plate is moved by the force of the spring to return to the original position and closes the ball hole.
