Then, when the cam plate 43 rotates in accordance with the drive of the electric motor 42, the hitting rod 5 is pushed by the cam plate 43 against the urging force of the elastic tension coil spring 18, and the elastic portion 5a shoots the ball. While tilting in a direction away from the mouth 8, the resilient part 5a is tilted in a direction to plunge into the ball launching mouth 8 by the resilient tension coil spring 18, and this reciprocal tilting is repeated. An electric motor drive limit switch 45 is attached to the motor set plate 3a below the electric motor 42, and is turned on and off by an operating rod 46 projecting from the interlocking rod 31.

Reference numeral 47 is a motor drive circuit unit attached to the motor set plate 3a, 48 is a condenser, and 49 is a single-shot switch (see FIG. 10).

The ball launcher assembly 1 configured as described above is fixed to the back surface of the operation panel 4 of the pachinko machine main body as described above.
As shown in FIGS. 4 and 5, the rotating shaft 50a of the operating handle 50 attached to the surface of the operating panel 4 is inserted into the operating handle connecting shaft 25 so as to be integrally rotatable as shown in FIG. ing. A touch switch 51 is built in the connecting shaft 25, and when a person touches the operation handle 50, the touch switch 51 operates to drive the electric motor 42.

Next, the hitting action of the electric pachinko machine will be described.

When the operating handle 50 is rotated, the operating handle connecting shaft
As 25 rotates, the touch switch 51 inside operates. By the rotation of the connecting shaft 25, the cam plate portion 26 causes the cam roller 29 of the driven lever 27 to return to the tension coil spring for returning.
It is pressed against the urging force of 30, and the interlocking rod 31 is pulled as shown in FIG. By the movement of the interlocking rod 31, the second and third rotating bodies 33, 34 rotate, and the engaging portion 40 thereof rotates in the direction of arrow A, as shown in FIG. Further, due to the movement of the interlocking rod 31, the operating rod 46 is separated from the limit switch 45, and the electric motor 42 is driven. When the output shaft 42a of the electric motor 42 rotates, its cam plate 43 presses the cam roller 44 of the ball striking rod 5, and the ball striking rod 5 tilts in synchronization with the rotation of the second and third rotating bodies 33, 34. To do. Due to this tilting, the slide plate 13 moves against the biasing force of the return tension coil spring 23,
The first rotating body 19 rotates. As a result of this rotation, as shown in FIG. 15, the engaging portion 41 of the first rotating body 19 rotates in the direction of the arrow B from the separated position to come into contact with the engaging portion 40 of the third rotating body 34. The ball feeding member 9 moves upward due to the tilting of the hitting rod 5, and the ball flows into the ball launching port 8.

When the operation handle 50 is stopped at an arbitrary rotation operation position, the engagement portion 40 of the third rotating body 34 is positioned, and the rotation of the engagement portion 41 of the first rotating body 19 abutting on the engagement portion 40 is prevented. Be blocked. Therefore, the first rotating body 19 and the slide plate 13 are also positioned,
The spring connecting portion 15 of the slide plate 13 is held at a fixed position. The hitting rod 5 tilts against the biasing force of the elastic tension coil spring 18 extended from the spring connecting portion 15.

When the cam plate 43 of the output shaft 42a of the electric motor 42 is separated from the cam roller 44 of the ball striking rod 5, the ball striking rod 5 is tilted by the urging force of the elastic tension coil spring 18 for moving the ball at the ball launching port 8. strike. Due to this tilting, the slide plate 13 and the first rotating body
Only 19 is returned to its original position by the urging force of the return tension coil spring 23, and the engaging portion 41 of the first rotary body 19 is rotated in the direction opposite to the arrow B from the state shown in FIG. It is separated from the engaging portion 40 of 34. When the operation handle 50 is kept in the constant rotation operation position, the engagement portion 40 of the third rotating body 34 is always in the constant position, so that the spring connecting portion 15 of the slide plate 13 is also maintained in the constant position and the elastic force is generated. Since the tension coil spring 18 for use is always stretched by the same size, the hitting rod 5 can repeatedly hit the ball with the same resilience.

When the rotation operation amount of the operation handle 50 is changed, the third rotating body
Since the holding position of the engaging portion 40 of 34 changes, the holding position of the spring connecting portion 15 of the slide plate 13 also changes. Therefore, the extension amount of the elastic tension coil spring 18 increases and decreases, and the elastic force of the hitting rod 5 can be changed.

Further, when the relative rotational positions of the second and third rotating bodies 33 and 34 are adjusted as described above, the position of the engaging portion 40 is changed as shown by the imaginary line in FIG. 13 to change the first rotating body. The separation distance of 19 from the engaging portion 41 can be changed. That is, the smaller the distance between the engaging portions 40 and 41, the smaller the operating handle 5 is.
A larger elastic force can be obtained with a turning operation amount of 0.

Particularly, in this embodiment, the engaging portion 41 of the first rotating body 19 is engaged with the second rotating body 34 so that the hitting rod 5 tilts against the biasing force of the elastic tension coil spring 18. The urging force of the spring 18 is applied to the operation handle 50 only when it abuts against the portion 40, but the urging force of the spring 18 is not applied to the operation handle 50 at the moment of rotating the operation handle 50, and the operation handle 50 This biasing force is only intermittently applied while the ball striking rod 5 is reciprocally tilted during the holding. Therefore, the player is less likely to feel fatigue when operating the steering wheel for a long time.

In summary, according to the present invention, it is possible to reduce the time for which the urging force of the spring 18 for operating the operating handle 50 is applied to the operating handle 50, so that the player is not tired especially when operating the operating handle for a long time. Less likely to feel. or,
The elastic force can be easily adjusted only by changing the contact positions of the engaging portions 40, 41 of the movable members 13, 19, 33, 34.
