The gutter is equipped with a sprocket-like rotating piece that regulates the inflow of prize balls, and the door and rotating piece are controlled by an operating plate and a stopper rod that are linked together, and a safe ball detection device prevents safe balls from entering. When detected, this is transmitted to the actuating plate via the interlocking rod to open the outflow restriction door that has been restrained in the closed state, and at the same time, the prize ball in the prize ball storage chamber is released, and the stopper rod is engaged with the rotating piece. to stop the rotation and stop the flow of prize balls from the prize ball guide gutter into the prize ball storage chamber, and at the same time, as the safe ball detection device is restored to its original state, the outflow restriction door is engaged with the actuating plate, and the closed state is again established. To provide a prize ball device which allows prize balls to flow in by separating a stopper rod from a rotary piece at the same time as binding, and which is particularly accurate in storing and discharging prize balls without malfunction, and which operates smoothly and quickly. There is a particular thing.

Next, this invention will be explained based on an illustrated embodiment, and its features will be explained in detail.

Figure 1 is an explanatory diagram of the state of use, showing the main part in cross section, Figure 2 is an enlarged rear view showing the back side of the main part in the above figure after removing it, and Figure 3 is a further illustration of the part in the above figure. FIG. 3 is an enlarged rear view of the main parts shown in an enlarged and partially cut-out manner.

In the drawings, 1 is a base frame plate made of a metal plate fixed to the back of a door frame 3 hinged to the front of the outer frame 2 of the pachinko machine, and 4 is attached to the upper back side of this base frame plate. 5 is a prize ball guide gutter with two parallel lines for guiding the prize balls from the storage tank 4 to the prize ball storage chamber described later; 6 is the prize ball according to the present invention including the prize ball storage chamber. It is a mechanism frame that integrally houses a device and a safe ball detection device that operates this winning ball device.

The mechanism frame 6 is a member formed around a substantially L-shaped base plate 7 made of plastic, and one side edge of the base plate 7 is hinged to one side edge of the base frame plate 1 via a pivot joint 8. , is attached to the back side of the board 7 (the side facing the base frame board 1), and the second,
A device for detecting safe balls and a means for transmitting the detection of this device to a prize ball device to activate it are provided on the side shown in Figure 3), and prize balls are stored on the other side (the side shown in Figure 1), It is equipped with a prize ball device that releases prize balls.

Now, in the figure, 9 is a safe ball passage provided on one side of the base plate 7 of the mechanism frame 6, and 10 is a shaft 1 near one end.
1, and its free end is connected to the above-mentioned safe ball passage 9.
12 is an interlocking rod that transmits the swinging motion of the detector to the operating plate 13 of the winning ball device.

On the other hand, 14 is a meandering part of the guide path that communicates with the prize ball guide trough 5 provided on the opposite side of the board 7, 15 is a prize ball storage chamber provided following this meandering part, and 16 is a prize ball storage chamber. It is an outflow control door that closes the bottom exit of the
17 is a sprocket-like rotating piece that faces the notch 18 formed in the meandering part 14 and regulates the balls flowing into the storage chamber 15; 19 is interlocked with the operating plate 13 to control the ball feeding rotation of this rotating piece. It is a stopper rod.

The meandering portion 14 of the prize ball guiding gutter 5 is provided so that its upper end faces the upper swinging end of the mechanism frame 6 and communicates with the prize ball guiding gutter when the mechanism frame is closed. It consists of two parallel passages arranged one behind the other in line with the guide gutter. The prize ball storage chamber 15 following this meandering part is provided with two longitudinally cylindrical chambers communicating with two passages, and the lower end exit of each chamber faces the prize ball discharge path 20 directly below.

The outflow control door 16 is attached at its upper end to a pin 21 so as to be able to swing freely, and due to the uneven distribution of its center of gravity, it always approaches the outlet of the storage chamber and blocks it at the same time.
A pin 22 implanted at the lower end of this swing is engaged with a notch-shaped engagement portion 23 provided in the actuating plate 13 to be restrained in this closed state.

On the other hand, the rotating piece 17 provided in the notch 18 of the meandering part 14 is rotatably supported on the shaft 24, and the pawl provided on the circumferential surface is inserted into the passage and the falling prize ball is caught between the pawl and the pawl. It is arranged so that one claw is sent for each passing ball. The stopper rod 19 is provided to swing around a support shaft 25, and one end is connected by sliding a pin 27 into a long hole 26 provided in the actuating plate 13, and the other end having a hook is rotated. It is arranged so that it faces the periphery of the piece.

The rotating piece 17 and the outflow control door 16 are connected to the operating plate 13.
When the safe ball detector 10 detects a safe ball and raises the interlocking rod 12, the outflow control door 16 is opened and the prize ball in the storage chamber 15 is released. At the same time, the rotation of the rotating piece is stopped and the flow of prize balls is stopped.

That is, to explain this relationship in more detail, when a winning safe ball enters the safe ball gathering 28 following the safe ball path 9 and enters the safe ball path, the detector 10 swings under the weight of the ball. , the interlocking rod 12 will be raised.

As a result, the actuating plate 13 supported by the pin 29 swings upward about the pin as a fulcrum and first disengages the pin 22 that engages with the engaging portion 23, and the outflow restriction door 16 closes the outlet of the storage chamber 15. In order to free the prize ball, the ball pressure opens this door and flows out into the prize ball discharge path 20. On the other hand, the stopper rod 19 connected to the operating plate 13 by sliding the pin 27 swings about the shaft 25 and hooks its pawl to the pawl of the rotary piece 17, so that free rotation is stopped. Along with this, the prize balls flowing through the meandering portion 14 are stopped when the rotation stops, and are prevented from flowing into the storage chamber 15.

FIG. 3 shows a series of operations for releasing the prize ball as the safe ball enters. Only the prize ball stored in the storage chamber 15 is released by the interlocking movement of the outflow control door 16 and the rotating piece 17. The ball that is then sent is stopped at the position of the rotating piece 17 and waits for its release.

Then, the safe ball passes through the safe ball passage 9,
As the detector 10, interlocking rod 12, actuating plate 13, and stopper rod 19 return to their original states, the outflow regulating door 16 engages the pin 22 with the engaging portion 23 and is restrained in the closed state, and the rotating piece is closed. 17 becomes free and lets the prize ball flow into the storage chamber.

The prize balls flowing into the storage chamber 15 are those that have entered between the door 16 and the rotating piece 17, and since this capacity is constant, a constant number of prize balls are always stored.

The device of the present invention is constructed as described above, and when the interlocking rod 12 operates in conjunction with the detection operation of the safe ball detector 10, the actuating plate 13 and the stopper rod 19 interlock, thereby opening the storage chamber. At the same time, the outflow control door 16 of No. 15 is opened and the prize balls stored inside are released, and at the same time, the rotation of the rotating piece 17 facing the entrance of this prize ball storage chamber is restrained, and the prize balls are immediately sent continuously along the prize ball guide path. Since the inflow of balls is stopped, only a constant number of prize balls are always discharged according to the capacity of the prize ball storage chamber 15, and this storage chamber is a simple vertical cylinder so that it is a part of the prize ball guiding gutter 5. Because of its shape, it is possible to release the prize ball extremely quickly, and even if there are many safe balls in succession, the prize ball can be released without delay.

In addition, in the device of the present invention, the rotary piece 17 that regulates the flow of prize balls flowing into the storage chamber 15 always faces the inside of the prize ball guiding gutter with a claw provided on the circumferential surface through the notch 18 to pick up individual balls. In other words, by making the spacing between the claws of the rotating piece constant according to the diameter of the ball, it is possible to feed out one by one as the ball rotates. Therefore, by stopping this rotation, it is possible to immediately stop the feeding of the ball, and at the same time, it is possible to stop the ball accurately, and at the same time, the inflow of the prize ball is stopped as the actuating plate 13 swings. The claw of the rotating piece is inserted between successive prize balls to regulate the ball cutting, allowing for accurate ball cutting.
This is effective in stabilizing the number of balls awarded.

In particular, in the method of stopping the flow by inserting a stopper or the like between the balls, there is a risk that the stopper and the balls may come into direct contact with each other and the ball cannot be inserted between the balls. Because a claw is inserted between the balls in advance to prepare for cutting the ball, it is possible to stop the flow at the same time as the rotating piece stops.

Furthermore, it is easier to engage the pawls of the stopper rod with the pawls of the rotating piece than to insert the pawls of the stopper rod between the balls, and the shapes of the pawls can be freely selected and designed. An engagement relationship can be obtained and more stable control is possible.
