A case which is provided with a case part and whose lower end is opened so as to discharge a predetermined amount of prize balls to be paid out at one time, or JP-A-5-1
As shown in Japanese Patent Publication No. 77032, a lead screw having spirally formed protrusions for receiving a prize ball is arranged on the outer peripheral surface between supply passages communicating with two ball passages of a tank rail, and the lead screw is rotated a necessary number of times. There is one in which a given amount of prize balls flowing down in both supply passages are discharged one by one. In the case of the tank rail, in the former case, the prize balls in each ball passage generally flow down side by side, but in the latter dispensing device, due to the discharge by the lead screw, both supply passages, that is, each ball of the tank rail. The prize balls in the aisle will flow down after being shifted by half a ball on the left and right. For this reason, the ball stopper member is provided with a dedicated one in which the claw pieces are parallel or shifted by half a ball so as to correspond to the prize ball payout device.

[0004]

As described above, since it is necessary to prepare different kinds of ball stopping members according to the prize ball paying device, the manufacturing is troublesome, and not only the mounting work on the pachinko machine is complicated. There was a problem that it made maintenance and management difficult. Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to provide a pachinko machine having a ball stopper member having excellent versatility so as to be compatible with any prize ball payout device. It is a thing.

[0005]

In order to achieve the above object, the present invention mounts a prize ball tank on the upper back surface of a mechanism plate mounted on the back side of a game board, and a plurality of ball passages below the tank. In a pachinko machine in which a tank rail having the same is arranged, a bent gutter is connected to the lower end of the tank rail, and a prize ball dispensing device is detachably connected to the bent gutter, a ball is attached to the lower end of the bent gutter. It is equipped with a stop member. The ball stopper member is movable along with a stop rod urged by a compression coil spring so that the tip projects into each ball passage of the bending trough, and is loosely fitted to the stop rod to be linked with the attaching operation of the prize ball dispensing device. It consists of a board.

When the prize ball payout device is connected, the movable rod and the stop rod retract from the ball passage to allow the prize ball in the ball passage to flow down. Supply. On the other hand, when the prize ball payout device is detached, the stop rod becomes free and the tip of the stop rod is projected into the ball passage by the bias of the compression coil spring so as to intervene between the prize balls and stop the flowing down prize balls. As a result, the supply of the premium balls to the premium ball dispensing device is stopped. Therefore, even if the premium ball dispensing device is removed, the premium ball does not fall out from the lower end of the bent gutter. Even if half of the prize balls are displaced in both ball passages of the bent gutter, the tip of one of the stop rods hits the side surface of the prize ball, and the prize coil is pushed out by the action of the compression coil spring. Since it is supported from the lower surface, the stop operation is not hindered and the supply of the prize balls can be stopped.
