2. Description of the Related Art Conventionally, in a ball removing device for a ball storage tray of this type, a stopper means is provided in the ball removing device, and a shutter plate for opening and closing the ball removing hole by the stopper means is provided at a position for opening the ball removing hole. It is known that it can be stopped and held (see, for example, Japanese Utility Model Laid-Open No. 5-9583).

[0003]

In the conventional ball-removing device for a ball storage tray, many moving parts are required, the structure is complicated, and the assembly is troublesome, and the cost is inevitably high. There is a problem that the stopper means cannot be released if the movable part is broken.

Further, even when there is no pachinko ball in the ball storage tray and it is not necessary to remove the ball, when the shutter plate is slid, the stopper means operates and the shutter plate is stopped and held at the ball removing position. Therefore, there was a problem that many ball storage trays of pachinko machines were left in the ball-removed state due to mischief or harassment.

The present invention has been made in view of the above problems of the prior art. The object of the present invention is that the structure is simple and the conventional device can be obtained without major modification. In addition, it is an object of the present invention to provide a ball-removing device for a ball storage tray in a pachinko machine that can stop and hold the shutter plate at the ball-removing position and is not tampered with by the player.

[0006]

In order to achieve the above object, the present invention provides a ball-draining hole in the bottom surface of a dish portion for storing pachinko balls, and a support frame is provided in the lower bottom portion of the dish portion. A ball removing device for a ball storage tray in which a shutter plate for opening and closing the ball removing hole is slidably supported on the support frame, and the shutter plate is always biased by a coil spring in a direction of closing the ball removing hole. In the above, a through hole is formed on the bottom surface of the dish so that one pachinko ball can be dropped, and the shutter plate has a first position where the ball punch hole is fully opened. In addition to providing a bending groove hole that can be accommodated, the supporting frame is provided with a bending concave groove corresponding to the bending groove hole and a ball dropping hole for dropping a pachinko ball accommodated in the bending groove hole, and the bending groove hole is formed as a whole. Formed in a gentle curved shape and set the middle position A push-out portion that extends over the curved groove at the first position of the batter plate, and a pachinko ball accommodated in the curved groove hole is brought into contact with the curved groove so that the shutter plate is almost fully opened. It is provided with an engagement surface for holding it in two positions.

Further, the shutter plate is provided with a character or a colored display for indicating that the shutter plate is in a ball-removed state at a position corresponding to the through hole of the dish when the shutter plate is held at the second position. Parts are provided.

[0008]

When the shutter plate is slid to the first position where the ball hole is fully opened, the tip of the bent groove hole of the shutter plate is aligned with the through hole on the bottom surface of the tray and is stored in the tray. One of the pachinko balls falls into the tip of the bending slot and is stored. If you release your hand from the shutter plate in this state, the shutter plate will slide in the direction to close the ball hole due to the biasing force of the spring. It abuts on the engaging surface of the groove, thereby preventing the shutter plate from sliding and holding the shutter plate at a second position where the ball hole is almost fully opened.

Then, when the shutter plate is again slid to the first position where the ball hole is fully opened from this ball-removed state, the shutter plate comes into contact with the engaging surface of the curved groove and stops and holds the shutter plate in the second position. The pachinko ball that has been used is pushed out by the pushing portion of the bending groove hole of the shutter plate and its engagement is released, and at the same time, the pachinko ball is guided by the bending groove hole and falls from the ball dropping hole. As a result, when the shutter plate is released, the shutter plate returns to the position where the ball hole is closed by the bias of the spring.

Further, the display means provided on the shutter plate indicates that the shutter plate is in a ball-removed state in conformity with the through hole on the bottom surface of the dish when the shutter plate is in the second position where the ball-removed hole is almost fully opened. Function to make people understand.
