Further, a columnar connecting shaft 46 is formed near the other end of the swing plate 60, and the connecting shaft 46 is inserted into a support hole 48 a provided at one end of the sliding plate 48. Here, the slide body 54, the slide plate 48, and the swing plate 60
The configuration according to is one of the configurations in which the driven means is embodied.

A column-shaped hooking portion 52 is formed near the other end of the sliding plate 48. The hook portion 52 is hollow, and the support member 52b is fitted through the guide groove 50b from the back side of the base 50. Here, the guide groove 50b
Is an elongated slot through which the sliding plate 48 (support member 52b) can slide horizontally.

The cylindrical support portion 50d formed near the center of the base 50 has a support hole 54a for the sliding member 54.
Fitting hole 58a provided in the adjusting knob 58
Is fitted to. The fitting hole 58a is formed in a stepped shape as shown in FIG. 5 (A2), and the support portion 50d is fitted to this stepped position. Further, a columnar meshing portion 56 is formed on the sliding body 54, and a circular convex portion is formed on the surface opposite to the surface on which the meshing portion 56 is formed, as shown in FIG. 5B2. The portion 56a is formed. This convex portion 56a
Is slidably fitted in the guide groove 50c of the base 50.

The adjusting knob 58 is a cylindrical member, and a flat plate 58b having a diameter larger than the cylindrical diameter is formed near the lower surface. Cam teeth 58c are formed in a spiral shape along the outer periphery (peripheral edge) of the flat plate 58b and mesh with the above-mentioned meshing portion 56. Here, the cam teeth 58c
Is one of the means of engagement. In this way, the adjustment knob 58
Since it is composed of a cylindrical member, it is possible to maintain a constant strength. The adjusting knob 58 is rotatably supported by being inserted into a support hole 68b provided in the case 68.

Here, a plurality of small holes indicating the positions of the knobs are provided at both ends of the adjusting knob 58 which is inserted into the supporting hole 68b of the case 68 and protrudes. The letters "strong" and "weak" and " The numbers "1" to "9" are engraved.
Further, a marker 58d is provided on the upper surface of the adjusting knob 58, and it can be used as a guide when adjusting the elastic force according to the positional relationship with the small holes corresponding to the above numbers, so management of the pachinko machine is possible. The person can set it while recognizing the strength of the resilience. Hereinafter, it is composed of the sliding plate 48, the base 50, the sliding body 54, the adjusting knob 58 and the swinging plate 60 described above, and adjusts the resilience of the ball striking rod 22 when hitting the pachinko ball 26. The mechanism will be referred to as an “elastic force adjusting unit”.

Next, the operation of the mechanism for adjusting the resilience of the striking rod 22 will be described with reference to FIGS. 6 and 7. Here, FIG. 6 is a diagram showing a positional relationship between the hitting rod and the elastic force adjusting portion. Further, FIG. 7 is a view showing an operating method when the elastic force of the hitting rod is adjusted by the elastic force adjusting unit.
7A shows the case where the elasticity is weakest, and FIG. 7B shows the case where the elasticity is strongest. 2 and 4
The same elements as those of 1 are denoted by the same reference numerals, and description thereof will be omitted.

First, in FIG. 6, when the adjusting knob 58 is rotated to the left with respect to the drawing, the position of the smallest diameter among the cam teeth 58c formed in a spiral shape and the meshing portion 56 mesh with each other. At this time, the adjustment knob 58 is attached to the support hole 6 of the case 68.
It is supported by 8b. Further, since the spring 44 hooked on the hooking portion 52 tends to urge to the left side in the drawing, the sliding body 54 also slides to the left side in the drawing through the connecting shaft 46 and the swing shaft 62. In this way, when the position of the minimum diameter of the cam tooth 58c and the meshing portion 56 mesh with each other, a positional relationship as shown in FIG. 7 (A) is obtained. In this case, the hook portion 42 and the hook portion 5 shown in FIG.
Since the spring 44 hooked between 2 has the weakest urging force, the resilience of the batting rod 22 is also the weakest.

Next, in FIG. 6, when the adjusting knob 58 is rotated to the right with respect to the drawing, the position of the maximum diameter of the spirally formed cam tooth 58c and the meshing portion 56 mesh with each other. At this time, the sliding body 54 slides to the right in the drawing, contrary to the above case. Thus, when the position of the maximum diameter of the cam tooth 58c and the meshing portion 56 mesh with each other, the positional relationship shown in FIG. 7B is obtained. In this case, since the spring 44 has the strongest urging force, the ball rod 22 also has the strongest elastic force.

Here, the cam teeth 58c formed on the adjusting knob 58 are formed into at least eight corrugated teeth in which the distance from the rotational axis is gradually increased stepwise by the clockwise rotation of the adjusting knob 58. Has been done. Therefore, the sliding body 54 provided with the meshing portion 56 is moved by the rotation of the adjusting knob 58.
The biasing force can be increased in each step. Further, the cam teeth formed on the adjusting knob 58 and having the smallest radial distance from the rotating shaft center are engaged with the meshing portion 56 to adjust the knob 5.
8 is formed in a shape that prevents left rotation. Therefore, it is possible to prevent the sudden expansion of the elastic force due to the leftward rotation of the adjusting knob 58.

That is, when the adjusting knob 58 is rotated in the left-right direction by a desired amount, the sliding body 54 slides in the left-right direction according to the rotation of the adjusting knob 58, and accordingly, the sliding body 54 is connected to the sliding body 54. The rocking plate 60 rocks. And
The slide plate 48 slides in accordance with the swing of the swing plate 60, and biases the spring 44 hooked on the slide plate 48 (specifically, the hook portion 52). In this way, the elastic force of the batting rod 22 can be adjusted by rotating the adjusting knob 58 by a desired amount with one touch.

Further, as apparent from FIG. 6, when the adjusting knob 58 is rotated to urge the spring 44 to adjust the initial elastic force, and then the handle 30 is rotated, the handle 30 is rotated. Spring 4 is further rotated according to the rotation of
4 can be activated. That is, the adjustment knob 5
For the elastic force that rotates 8 to urge the spring 44,
Since the elastic force for rotating the handle 30 and urging the spring 44 is applied, the ball striking rod 22 hits the pachinko ball 26 with various elastic forces, and the pachinko ball 26 is moved. Can be fired.

Next, the case 68 will be described with reference to FIGS. 4 and 8. The case 68 is a transparent or translucent member, and as shown in FIG. 8, a scale 68b is provided around the support hole 68b through which the adjustment knob 58 is inserted. Therefore, it is possible to easily recognize the current position where the cam tooth 58c and the meshing portion 56 mesh with each other, together with the marker 58d provided on the upper surface of the adjustment knob 58 shown in FIG.

Further, as shown in FIG. 8, by mounting the case 68 so as to cover the elastic force adjusting portion, the elastic force adjusting portion can be surely protected. Further, the roller 68a is attached to the case 68 so as to support the spring 44.
By being provided at one of the four corners, the ball striking rod 22 that swings with the urging force (expansion and contraction) of the spring 44 transmitted by the rotation of the motor 10 operates smoothly. At the same time, the elastic force can be adjusted smoothly by rotating the adjusting knob 58.

Although one embodiment of the ball launching device of the pachinko machine has been described above, the structure, shape, size, material, number, arrangement and operating conditions of other parts of the ball launching device of the pachinko machine are also described. However, the present invention is not limited to this example. For example, the adjustment knob 5 shown in FIG.
Instead of 8, the contact portion 59a is formed in a spiral shape along the outer periphery of the collar 59b, and the contact portion 59a contacts the meshing portion 56 of the sliding body 54. The provided adjustment knob 59 may be applied to the present invention. At this time, it is desirable that both the contact portion 59a and the meshing portion 56 are surfaces (rough surfaces) having a resistance force sufficient to resist the biasing force of the spring 44. If this adjusting knob 59 is applied to the present invention, the sliding body 54 can be continuously slid in accordance with the rotation of the adjusting knob 59.
The resilience of 2 can also be adjusted continuously. For this reason, if the adjustment knob 59 is rotated little by little, the striking rod 2
The resilience of 2 can be fine-tuned.

Further, as shown in FIG. 10, in addition to the hooking portion 42, at least one other hooking portion 42 is provided on the ball striking rod 22.
If a is provided, the spring 44 can be detachably attached between any one of the engagement portions and the engagement portion 52 provided on the slide plate 48. For this reason, the hooking portion 42 and at least one other hooking portion 42a are formed whenever necessary.
In addition to the operation of the adjusting knob 58 and the handle 30, the urging force of the spring 44 can be changed, and thus the resilience of the batting rod 22 can be changed.

Further, the adjusting knob 58 and the sliding member 54 are configured to slide the sliding plate 48 through the swinging plate 60 to urge the spring 44, but the adjusting knob 58 and the sliding member 54 are integrally formed. Even if the other adjusting knob is directly moved (slide) to slide the sliding plate 48 via the swing plate 60 to urge the spring 44, the same effect as in the above embodiment can be obtained. .

Although the spring 44 (a spiral spring) is applied as one of the springs to the elastic body, the present invention is not limited to this, and another spring such as a leaf spring or a torsion spring may be applied. Further, even if another elastic member having elastic force such as rubber, air cylinder, hydraulic cylinder, etc. is applied, the same effect as in the above embodiment can be obtained.

Then, the cam teeth 58c provided on the adjusting knob 58 are structured so that the meshing portion 56 is locked by the biasing force of the spring 44, so that the striking rod 22 for each cam tooth 58c is pulled through the spring 44. The force can be securely held and the resilience of the batting rod 22 can be set. Since a large number of grooves for preventing slippage are axially engraved on the outer circumference of the adjusting knob 58, a large frictional force is ensured when the adjusting knob 58 is rotated. Therefore, the turning operation of the adjusting knob 58 can be easily performed.

Since the cam teeth 58c and the meshing portion 56 are formed of a resin material, it is not necessary to lubricate the cam teeth 5c.
The engagement state between 8c and the meshing portion 56 can be kept smooth forever. The diameter of the adjusting knob 58 is formed to be approximately the size of a thumb, the amount of turning operation with a fingertip is reduced, and the resilience of the ball striking rod 22 can be adjusted. Since the hooking portion 52 of the spring 44 is provided with a semicircular projection, it is possible to prevent the spring 44 from coming off the hooking portion 52 when the firing device is operating. Further, the spring 44 is attached to the hook portion 52.
It can also be easily hooked on.

A control knob 58 provided on the back surface of the pachinko machine body is rotated and set by the manager of the pachinko machine so as to have a predetermined range of elastic force, and a handle provided on the front surface of the pachinko machine body. Since the player adjusts the elastic force of the pachinko ball within the above predetermined range, adjustment of the elastic force to the back surface of the pachinko machine body which is difficult to operate operates the handle 30 on the front surface of the pachinko machine body. It can be set with the same ease as the above.

In FIG. 11, when the handle 30 on the front surface of the main body of the pachinko machine is turned to the right, the cam plate 94
2, the linkage rod 66 is pulled to the left in FIG. 2, and the sliding plate 48 slides to the right with the swing shaft 62 as the fulcrum. Then, the spring 44 hooked between the hook portion 42 and the hook portion 52 is continuously pulled to gradually increase the biasing force. With this configuration, when the adjustment knob 58 on the back surface of the pachinko machine body is rotated rightward in FIG. 2, a (cam) flat plate 58b provided on the adjustment knob 58 is provided.
The plurality of cam teeth 58c formed on the outer periphery of the tooth move sequentially and hold the meshing portion 56 for each tooth. At the same time, the batting rod 22
The spring 44 stretched over the hooking portion 42 is discontinuously pulled by the hooking portion 52 via the swing shaft 62, the swing plate 60, and the connecting shaft 46.

Therefore, since the urging force is increased stepwise, even if the urging force of the spring 44 is set stepwise by the turning operation of the adjusting knob 58 on the back surface of the pachinko machine body, the pachinko machine body is not affected. When the handle on the front side of the control knob 58 is operated, the elastic force can be adjusted continuously and beyond the setting range of the elastic force by the cam teeth 58c of the adjusting knob 58. In particular, the handle 30 on the front of the pachinko machine body and the adjusting knob 58 on the back of the pachinko machine body are each operated with one hand to rotate both the handle 30 and the adjusting knob 58 at the same time. The resilience of the sphere can be set to an optimum state.

[0041]

As described above, according to the present invention, when the adjustment knob is rotated, the engaging means discontinues the elastic body hooked at the other end of the striking rod through the driven means. Since it is configured to be engaged with, the elastic force of the batting rod can be adjusted by a one-touch operation of rotating the adjustment knob.

Further, when the adjusting knob is rotated, the engaging member is engaged in accordance with the rotation of the adjusting knob, and accordingly, the connecting plate connected to the engaging member is connected, and the connecting plate is connected. Since the engaging plate is engaged in accordance with the joint and the spring hooked on the engaging plate is configured to be biased, it is possible to adjust the resilience of the striking rod simply by rotating the adjusting knob. it can. Therefore, the labor required to adjust the resilience of the batting rod can be kept low. Even if the adjusting knob is continuously rotated and rotated, the resilience of the ball is set discontinuously on the back surface of the pachinko machine. Then, the stepwise setting can be performed by the engagement between the cam teeth and the meshing portion.
