lb is provided on its support shaft. Therefore, similarly to the embodiment shown in FIG.
The engagement uneven portion 59b of the second transmission ring 59 provided on the take-up base plate 31 engages with each other to transmit the rotation of the operating handle 9 to the ball launcher 30 side, causing the winding ring 44 to rotate. A switch 18 is provided at the bottom of the sector gear 18a to start the drive motor 57 when the operating handle 9 starts rotating.

On the other hand, the relationship between the ball launcher i30 and the launch rail device 20 will be explained based on FIGS. 11 and 12.
FIG. 1 is an illustrative front view showing the relationship between the ball launcher 30 and the launch rail device 20, and FIG. 12 is an exploded perspective view of the launch rail device 20. In FIG. 12, the launch rail device 2
0 consists of a support board 21, a launch point rail 22 screwed onto the support board 21, and a plastic contact member 23 that comes into contact with the upper part of the pachinko ball at the base of the launch point rail 22. The support board 21 has a plurality of protruding bosses 21a to 21d for attaching the launch point rail 22, and a screw hole 24 for attaching the contact member 23.
a, 24 b and installation to the game board 5 through holes 25a to 25f
is drilled. In addition, on the surface of the support board 21, there is a positioning protrusion 2B for easy attachment to the game board 5.
A shaft pin 27 that swingably supports a ball feed lever 28 is projecting from the lower part of the firing point rail 22 on one surface.

The ball feed lever 28 has a vertical rod 28a and an engaging pin 28b, and the vertical rod 28a is linked to the linking lever 52 of the ball batting rod 50 to feed the ball in response to the tilting of the ball batting rod 50. A ball feeding device (not shown) that engages with the engagement pin 28b by swinging the pin 28 feeds pachinko balls one by one onto the shooting point rail 22.
2 is attached along one side edge with bosses 21a to 21d.
In the mounting corresponding to the above, the pieces 22a to 22d are bent and stand up vertically at the base thereof, and a ball hitting hole 28 is provided through the rising part. Further, the firing point rail 22 is formed in a V-shaped cross section in the longitudinal direction, and the pachinko balls are supported and stabilized at three points by the seven-shaped rail and the contact member 23 at the base thereof. The firing rail device 20 configured as described above is attached to the game board 5 so that the hammer tip spring 51 of the ball hitting rod 50 accurately faces the ball hitting hole 28 of the firing point rail 22, as shown in FIG.

The operation of the embodiment described above will be described below. When the player turns the operating handle 9, the drive motor 57 is turned on and the first transmission ring 17 rotates and engages with the first transmission ring 17. The second transmission ring 59 also rotates. and the second transmission ring 59 and the cable 61
The winding ring 44 connected to the coil spring 46 rotates and strengthens the biasing force of the coil spring 46. In this state, the drive blade 58 of the drive motor 57 is moved to the drive lever 48.
By engaging with and pushing down the ball striking rod 50 which rotates together with the drive lever 48, the ball striking rod 50 is pushed down against the biasing force of the coil spring 46, and the drive blade 58 and the drive lever 48 are pushed down.
At the same time as the ball is disengaged, the ball striking rod 50 rapidly returns to its original position due to the biasing force of the coil spring 4B, and the hammer tip spring 51 causes the pachinko balls on the launch point rail 22 to be ejected. If the amount of rotation of the operating handle 9 is increased, the amount of rotation of the take-up ring 44 will also be increased, and the biasing force of the coil spring 46 will be proportionally increased, so that the firing force of the pachinko balls will also be increased. On the other hand, if the amount of rotation of the operating handle 9 is small, the firing force will be weak. Note that if the coil spring 4B wears out due to long-term use, the locking position of the ball hitting force adjustment groove 44b that locks one end 46a of the coil spring 46 may be changed, or the position of the rotating roller 63 may be changed. You can easily adjust the batting force by changing the pitch. In addition, in the above embodiment, the coil spring 46
Although one end of the drive cover 47 is shown to be locked to the drive cover 47, the present invention is not limited to this, and basically it may be locked to a member that rotates integrally with the handle shaft 40, that is, a handle shaft system member.

As is clear from the above description, the present invention has a spring biasing spring for elasticity in a bearing tube that is formed on a mounting board and that pivotally supports a handle shaft provided with a batting rod, and is compatible with the rotational operation of the operating handle. By attaching a take-up ring that rotates with the spring, and locking one end of the spring for elasticity to the take-up ring and the other end to the handle shaft system members including the batting rod, the spring is extremely narrow. The ball firing mechanism is configured in a space, making the overall work easier and increasing production efficiency.
