And the discharge gap F of each of the balls is connected to each other by a passage, and the slide tray M is provided with a slide knob M. The slide knob M is provided so that the discharge port K can be opened. Can be discharged to the prize ball saucer 27.

Since the first embodiment has the above-described structure, as shown in FIG. 4, the opening / closing frame member 7 provided on the front frame 2 mounted on the outer frame member 1 so as to be openable / closable is provided with the ball firing mechanism 9. ,
When the pachinko balls B are stored in the ball tray portion 8 provided on the opening / closing frame member 7 and the ball firing mechanism 9 is operated, the balls are fed one by one from the ball firing mechanism 9 on the opening / closing frame member 7 side to the game board on the front frame 2 side. Therefore, the balls are separately supplied and fired by the ball firing mechanism 9 provided on the opening / closing frame member 7, that is, the firing unit and the ball feeding unit are arranged on the opening / closing frame member 7. Since it is configured, the structure is simplified, the linkage between the opening / closing frame member 7 side and the front frame 2 side is not required, and the assembly structure of the front frame and the opening / closing frame member can be simplified, and the ball firing mechanism is also provided. Since all 9 are arranged on the front frame 2 side, maintenance can be performed easily.

In the case of this ball firing mechanism 9, first, as shown in FIG. 7, the rotary holder 12 is stopped and waits at the origin position S, and the ball B put in the ball tray 8 is on the back side of the open / close frame member 7. Is fed to the feeding path 16 disposed in the
Three balls are sent to the alignment surface 20b of the mooring member 20 via the, and the balls in the front row on the alignment surface 20b are moored to the mooring surface 20a. In this state, the player operates the operation handle of the operation handle portion 22. When 25 is rotated, the main shaft 11 of the rotary drive motor 10 starts to rotate, and this rotation causes the rotary holder 12 to start clockwise rotation and continue idle rotation, as shown in FIG.
By rotating clockwise from the separation / supply start position a, both edges of the tip of the rotary holder 12 pick up the balls in the front row moored on the mooring surface 20a, and by further rotation, one ball is received in the ball receiving portion 13. Thus, as shown in FIG. 10, the rotary holder 12 stops at the origin position S in the state of receiving the balls.

At this origin position S, the operating handle 2
When 5 is in the rotating state, the rotation holder 12 immediately restarts rotation as shown in FIG. 11, and in the state of FIG. 12 during the rotation, the balls move to the inside of the ball receiving portion 13 by their own weight, and then rotate. The rotation speed of the holder 12 gradually increases, and the balls move radially outward in the rotation holder 12 due to centrifugal force as the rotation of the rotation holder 12 accelerates.
The balls moving outward in 2 come into contact with the guide surface 18 of the guide member 14 arranged in the rotation area of the rotation holder 12,
Therefore, as shown in FIG. 13, the ball is accelerated and guided by the rotation of the rotary holder 12 and the constraint by the guide surface 18, and the accelerated ball is restrained by the rotary holder 12 and the guide surface 18 at the tangential position E at the latest as shown in FIG. It will be released from and will be discharged and emitted on the game board 4 via the guideway 19 and the launching path 5.

If the operation handle 25 is in the rotating state, the rotary drive motor 10 stops at the S position and immediately thereafter the ball drive operation as described above is repeated by continuous intermittent rotation of the rotary drive motor 10. When the hand is released from the handle 25, the operation handle 25 rotates back and the rotary drive motor 1
0 will stop and ball firing will stop.

The pachinko balls B thus sequentially sent are fed to the ball receiving portion 13 of the rotary holder 12, and the rotary holder 12 rotates and rotates while the balls are received in the ball receiving portion 13. Ball B is generated by centrifugal force as the holder 12 rotates.
Moves outward in the rotary holder 12, and the balls moving outward in the rotary holder 12 come into contact with the guide surface 18 of the guide member 14 arranged in the rotation area of the rotary holder 12, The balls are accelerated and guided by the rotation of the rotary holder 12 and the restraint by the guide surface 18, and the accelerated balls are rotated.
And, the ball is released from the restraint by the guide surface 18 and can be discharged and emitted onto the game board 4 through the launch path 5. Therefore, unlike a conventional pachinko machine, a ball can be emitted without hitting. The alignment of the tip of the striking lever with the center of the striking ball is not necessary, and the pachinko machine can be assembled easily and in an extremely short time without requiring any skill, and the rotary drive motor 10 can rotate the rotary holder 12. Since a small motor with a small torque to rotate the motor is sufficient, it does not require an excessively large mounting space, the flexibility of the space for arranging the components can be improved, and the ball firing hardly causes impact vibration or noise. Therefore, the frequency of consumption of the components can be reduced and the noise can be released.

Further, the balls to be fired are received in the ball receiving portion 13 of the rotary holder 12, and the guide member 14
Since the vehicle is accelerated while being guided by the guide surface 18, the desired firing force can be arbitrarily given by appropriately setting the shape of the guide surface 18, and in combination with the output of the rotary drive motor 10, the pachinko machine specifications. It is possible to easily set a firing condition that suits the requirement, and to prevent the ball from jumping or dancing in the ball receiving portion 13 by the guide surface 18, and to fire the ball smoothly in a stable state.

At this time, the guide surface 18 is attached to the rotary holder 12
By forming it on the surface of which the distance from the rotation center O of the rotary holder 12 gradually increases in accordance with the rotation, the starting torque of the rotary drive motor 10 can be reduced, and the motor can be made smaller and lighter.

The second embodiment of FIG. 14 and the third embodiment of FIG. 15 show another example structure. In the first embodiment, the rotation center O of the rotary holder 12 and the ball movement of the ball receiving portion 13 are moved. Although the axis N is on the coaxial line, in the case of these second and third embodiments, the rotation center O of the rotation holder 12 and the ball movement axis N of the ball receiving portion 13 are on the front side or the rear side. It is configured with displacement.

Therefore, in the second embodiment, the ball pick-up time by the rotary holder 12 is slightly delayed, and in the third embodiment, the ball pick-up time by the rotary holder 12 is slightly advanced. It is possible to change the positional relationship between the balls being held and the rotary holder 12 and the releasing position of the balls.

The fourth embodiment of FIGS. 16 to 19 shows another structure of the rotary holder. In this case, the rotary holder 12 is provided with a blind hole-shaped ball receiving portion 13, and the rotary holder 12 has the stepped portion. The escape groove 12c having a width slightly larger than the plate thickness of 14a and the plate thickness of the mooring member 20 is formed.
The collision interference between the guide member 14 and the mooring member 20 is prevented.

Even in the second to fourth embodiments, the same operational effect as the first embodiment can be obtained.

The present invention is not limited to the structure shown in the above embodiment, but the structure of the opening / closing frame member 7, the structure of the rotary holder and the ball receiving portion, etc. may be modified appropriately for design.

In the above embodiment, the origin position is set to the point S. However, if the supply start position a is the origin, for example, the initial idle rotation at the start of firing is eliminated and the ball is fired from the beginning. You can start.

When the balls are stored and the ball firing mechanism is activated, the balls are fired one by one from the ball firing mechanism on the opening / closing frame member side to the game board on the front frame side. It is made by the ball launching mechanism provided on the opening / closing frame member side, that is, the launching part and the ball feeding part are arranged on the opening / closing frame member, so that the structure can be simplified, and the opening / closing frame member side and the front frame side. Since the linking relationship with the front frame and the opening / closing frame member is not required, the structure for assembling the front frame and the opening / closing frame member can be simplified, and since the ball firing mechanism is disposed on the front frame side, maintenance can be performed easily.

Further, the above-mentioned ball launching mechanism is completely different from the conventional pachinko machine and can launch a ball without hitting, and the centering of the tip of the hitting lever and the center of the hitting ball becomes unnecessary, The pachinko machine is easy to assemble, the structure is simple, the mounting space is not so large, the flexibility of the space for arranging the components can be improved, and the ball firing can cause almost no impact vibration or noise. Since it does not occur, the frequency of consumption of the constituent parts can be reduced, the noise can be released, and the ball can be fired smoothly.
