The present invention has the above-described structure, and its operation will be explained next.

First, the balls supplied to the prize ball tank 15 from the prize ball supply gutter 18 disposed above the gaming machine main body are partially transferred from the lead-out gutter 16 to the branch gutter 46 as a game element separate from the prize balls. The ball is guided through the feed trough 47 to the inlet 38 and continuously supplied into the ball passage 35 communicating with the firing position 9.

At this time, the foremost game element B fits into the special part 37 formed in the ball passage 35 and is prevented from moving to the firing position 9, as shown in FIGS. 6 and 7, and remains at that position. It will be done.

On the other hand, when the player puts rented balls into the upper ball tray 5, the balls continuously face the outer peripheral surface of the rotating disk 57 from the ball outlet 25 through the inlet 50.

In this state, when the rotating bundle I is turned in the direction of the arrow shown in FIG. The rotating disk 57 rotates in the direction of the arrow in FIG.

When the foremost rental ball B1 matches the recess 58 of the rotating disk 57, the rental ball B1 enters the recess 58, and the twelfth rental ball B1 enters the recess 58.
As shown in the figure, as the rotating disk rotates 570 times, the rental ball B
1 pushes up the detection piece portion 71a of the rental ball detection member 71.

In response to this operation, the swinging member 59 moves the operation piece 71 of the ball rental detecting member 71 that comes into contact with the protruding edge 73 of the upper arm 64.
The roller 63 at the upper end of the plate cam 60 is swung by the plate cam 60.
comes into contact with the cam surface of the

At this time, the working pin 65 of the lower arm 66 is connected to the firing rod 8.
Immediately before the tip bent portion 91 of 0b, that is, the firing rod 8
Move to a very close position such as °C where it does not affect 0b.

As the rotating disk 57 continues to rotate, the plate cam 60 acts on the roller 63 as shown in FIG.
9 is further swung in the direction of the arrow, and at the same time, the firing rod 80b is pulled in the direction of the arrow by the action pin 65 against the spring 90.

When the firing rod 80b is pulled, the firing rod 80a moves upward via the connecting plate 7B, rotating the firing gun 27 from the solid line in FIG. 5 to the chain line.

As a result, the control piece 39 of the firing machine 27 rushes into the ball passage 35 from the opening 36 and pushes the foremost game section B located in the special machine section 37, causing the game section B to push the special machine section 37. Have them climb over and move to firing position 9.

When the rotary disk 57 makes one rotation, the roller 63 of the swinging member 59 moves away from the plate cam 60 and returns to its original state due to the action of the spring 68, as shown in FIG. The firing rod 80b, which was engaged and pulled, is released from the engagement and becomes free.

As a result, the firing hammer 27 instantaneously returns to the state shown by the solid line in FIG. 5 due to the action of the spring 900, and the hammer head 4
0 causes the gaming section B at the firing position 9 to be fired at the gaming section 8a.

When the firing button 27 is in the state shown by the chain line in FIG. The game part B2 was held at the side end by being held at the position and the firing hammer 27 returned to the state shown by the solid line in FIG.
is sent to the special equipment section 37 in the ball passage 35.

In this way, the balls from the prize ball supply gutter 18 are fired as a game part, and one ball is supplied to the firing position for each firing operation of the hammer 27.

The rental ball B1 is rotated by the guide frame 6 as the rotary disk 57 rotates.
2 and is discharged to a predetermined discharge route (not shown).

Out of the game part B fired by the firing hammer 27 to the game part 8a, out balls are discharged from the out ball opening 14 through the out ball ejection gutter 23 to the ejection path in the same way as the rented balls B, is discharged to a discharge route via a tamale 21 and a winning discharge gutter 22.

Moreover, the prize balls are discharged from the prize ball case 17 by the above-mentioned prize and guided to the upper ball tray 5 through the prize ball discharge gutter 20, and can be used as rental balls for firing the game part.

In this embodiment, the motor 55 has a specification of 98 revolutions per minute, and the motor 55 rotates the rotating disk 57 at 98 revolutions per minute.
8 rotations, 98 rental balls are transferred per minute, and the rental ball detection member 71 is synchronized with each rental ball as described above.
．． The game part is fired by operating the swinging member 59, the firing rods 80a and 80b, and the firing hammer 27.

Further, if there are no rental balls, the rotating disk 57 simply spins idly, and the rental ball detection member 71 is not swung, so that the game section is not fired.

Further, in this embodiment, as shown in FIG. 7, a micro switch 92 for detecting game balls is provided at the side end of the feeding gutter 47.
When the game part sending to the firing position 9 is interrupted, the microswitch 92 is activated to stop the motor 55, thereby preventing a situation where only the rented balls are ejected.

This makes it possible to have a complete one-to-one correspondence between rental balls and gaming sections.

When the rotation angle of the rotating bundle 7 is adjusted, the spring 90 is adjusted via the adjusting wire 85, lever 88, and spring adjusting piece 89.
The tension of the ball is increased or decreased, and thereby the flight distance of the game part can be adjusted freely.

When the hand is released from the rotating bundle I, the rotating knob 7 returns to its original position by the action of the spring 90, the microswitch 84 opens, and the motor 55 stops.

As described above, the present invention provides the rotary disk 57 for transporting rental balls.
A plate cam 60 is integrally attached to the plate cam 60, and a rental ball detection member 71 that swings in contact with the rental balls is provided. Another swinging member 59 is provided which is given a swinging motion, and the swinging of this swinging member 59 causes the firing rods 80a, 80
Since the firing hammer 27 is actuated to fire via b, and the game section at the firing position 9 provided on the upper side of the game board is fired, the rental ball detection member 71 and the swinging member 59 are separate members. By interlocking with each other, the swinging member 59 can be actuated with a small force by utilizing the lever action of the ball rental detecting member 71, and the swinging member 59 can be moved against the plate cam 6.
Due to the shape of the circumferential surface of the ball 0, it is possible to easily generate a sufficient stroke necessary for the firing operation of the ball rental ball detection member 71 and the swinging member 59.
By forming the peripheral surface of the plate cam 600 into a smooth curved surface, the pulling action of the firing hammer 27 is performed extremely smoothly, and therefore a large load is not applied to the motor 55. Furthermore, the firing operation of the firing hammer 270 is performed reliably.

Furthermore, by bringing the swinging member 59 into contact with the circumferential surface of the plate cam 60, the movement of the swinging member 59 is reliably and smoothly transmitted to the firing hammer 27, thereby reducing the impact and noise associated with the firing operation of the game section. It can be made extremely low, allowing for light play.

Furthermore, the firing hammer 27 is integrally formed with a control piece part 39 that goes in and out of the ball passage 36 and supplies the game parts one by one to the firing position 9, and a hammer head 40 that fires the game parts at the firing position 9. Since the operation of supplying the game part to the firing position and the operation of firing the game part are performed in one operation by swinging the swinging member 59, the timing of supplying the game part and the firing operation are not disturbed. There is no possibility of this occurring, and the game part can be accurately fired in synchronization with the number of rented balls by the number of rented balls.

Therefore, compared to a configuration in which, for example, the feeding operation to the firing position of the gaming section and the firing operation of the gaming section are performed by separate members, timing adjustment can be omitted, and the structure can be significantly simplified and failures can be avoided. It has many practical effects, such as being able to improve the efficiency of assembly work.
