行いにくいという欠点があつた。(Prior art) The ball device of a pachinko machine uses an electric cam to drive a ball mallet to perform a ball motion, and the strength of the ball spring can be controlled by the player using a ball handle. In addition to this structure, a ball force adjustment device is also provided so that the spring strength can be adjusted by the pachinko parlor. A typical conventional ball force adjusting device has a shape shown in FIG. A large number of sharp clutch teeth 51 are provided as shown in the figure, and normally they are pressed against each other by a spring to mesh so that relative rotation does not occur. Both discs were separated to allow relative rotation by a desired number of teeth. However, the conventional system had the disadvantage that it was difficult to tell how many rotations the disks had been rotated relative to each other during operation because they could not be rotated relative to each other unless the two disks were completely separated. In order to overcome this drawback, clutch teeth 52 that are inclined on both sides are sometimes provided as shown in Fig. 6, but such a tooth profile loosens and becomes loose when a strong axial force is not applied. Since there is a risk of the device rotating, it is held down by an extremely strong spring, which has the disadvantage of making adjustment work difficult.

An inclined surface 21 is formed. In the illustrated embodiment, the inclined surface 20 is set at approximately 45 degrees with respect to the rotating surface of the disc, but the angle is not necessarily limited to this, and the angle of the small inclined surface 21 can also be selected as appropriate. Note that a shaft 22 is integrally attached to the first disc 10, and the second disc 11 is rotatably supported on the outer periphery of this shaft 22.

整も行い易い利点がある。(Function) In the device configured as described above, the first disk 10 and the second disk 11 are normally connected as shown in FIG.
and are engaged with each other by a large number of clutch teeth 16 formed on the joint surfaces of both, so when the first disc 10 is rotated via the wire 14 by operating the ball handle 2, the second disc 10 is rotated. 11 also rotates integrally, and the gear 15 on the outer periphery of the second disk 11 rotates the gear 3 in which the spring 4 for the bullet is housed to change the spring strength. This allows the force to be adjusted. In the present invention, there is a disc 1 in the tooth profile of the clutch tooth 16.
Since the locking surface 19 is formed substantially perpendicular to the rotating surfaces of the disks 1 and 11, in the state shown in FIG.
The locking surfaces 19 of the clutch teeth 16 of 0 and 11 come into contact with each other on a plane perpendicular to the rotating surface,
Since no force is applied in the direction of separating both disks 10 and 11, there is no need to make the elastic force of the spring 18 very strong. In addition, when adjusting the ball force on the pachinko parlor side, the shaft 22 is pushed in slightly against the spring 18, and as shown in FIG.
The first disk 10 is shifted in the axial direction to a position where the two disks touch each other. If the first disk 10 is rotated via the shaft 22 in this state, both clutch teeth 16 will rotate easily due to the sliding action of the small inclined surface 21, and each time they pass over one tooth profile, a clicking sound will be heard. stand up. Therefore, the ball force adjustment device of the present invention allows you to easily know how many pitches have been adjusted even in a noisy pachinko hall, and also allows you to adjust the ball force without making the spring force of the spring 18 very strong. There is no need to worry about the clutch teeth 16 coming off each other, so there is an advantage that adjustments can be made easily.
