DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball-and-ball apparatus for a pachinko machine using a winding spring as a ball-and-ball spring.

[0002]

2. Description of the Related Art An electric pachinko machine incorporates a spring force adjusting mechanism operable at a pachinko parlor in addition to a ball force adjusting mechanism operated by a player using a handle. In the case of a pachinko machine in which the winding spring is a ball spring, the ball force adjusting mechanism connects the drum on which the ball spring is mounted to the handle side with a wire or the like, and when the handle is rotated, this drum rotates. It has a structure that changes the strength of the spring for bullets. The spring force adjustment mechanism is provided between the handle and the drum, and can change the rotation angle of the drum with respect to the rotation angle of the handle by using a ratchet mechanism.

However, conventionally, the spring force adjusting mechanism on the pachinko parlor side including the ratchet mechanism is provided separately at a position away from the rotation axis of the ball hammer. In addition to the rotary shaft and the ball-and-ball motor, many devices such as a spring force adjusting mechanism and a handle must be incorporated, and there is a problem that a large space is required. Further, conventionally, these devices are connected via gears and wires, so that there is a problem that the number of parts is large and the product cost is high.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and provides a pachinko machine capable of reducing space and reducing product cost by integrating equipment mounted on a board of a ball-and-ball apparatus. This was made to provide a ball-and-ball device.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a short cylinder portion protruding from a surface of a substrate.
The rotation axis of the ball hammer is rotatably supported inside the
Attach a ball hammer to the back side of the board, and
A helical spring is provided on the outer circumference of the short cylindrical part of
And a slide shaft provided with a ratchet plate for adjusting the spring force of the ball-and-ball spring is coaxially mounted with the rotation shaft of (1).

Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a ball-and-ball device of a pachinko machine according to the present invention as viewed from a board side, FIG. 2 is a perspective view as viewed from a back side, and FIG. 3 is a rear view. FIG. 4 is a plan view showing a main part cut away, and FIG. 5 is an enlarged sectional view of the main part.

1 to 3, reference numeral 1 denotes a board of a ball-and-ball device directly mounted on a base of a pachinko machine;
Reference numeral 4 denotes a rotating shaft on which a ball hammer is integrally fixed, 5 denotes a ball motor, and 6 denotes a ball cam. The ball device of the present invention also rotates the ball hammer 3 to the position shown by the imaginary line in FIG.
Further, when the ball cam 6 rotates and comes off from the end of the ball hammer 3, the ball motion is performed by the spring force of the ball spring 7, which will be described later, as in the conventional one.

[0006] Figure 4, as shown in FIG. 5, the rotation shaft 4 of Tamadamatsuchi 3 is rotatably supported by a bearing 9, 9 of the short tube portion 8 projecting from the surface of the substrate 1, the Of the substrate 1 of the rotating shaft 4
A bullet hammer 3 is attached to the back side. This rotation axis
A first ratchet plate 10 having ratchet claws is fixed to the front end of the substrate 1 of No. 4. Accordingly, the ball hammer 3, the rotating shaft 4, and the first ratchet plate 10 always rotate integrally.

[0007] A slide shaft 11 is provided coaxially with the rotary shaft 4 so as to be slidable in the axial direction of the rotary shaft 4.
A second ratchet plate 12 that meshes with the first ratchet plate 10 is integrally provided at an end of the slide shaft 11 on the front side of the substrate 1 . And the back surface of the substrate of the slide shaft 11
A compression spring 14 between a knob 13 provided at the end on the side and the rotary shaft 4 always pulls the slide shaft 11 and the first ratchet plate 10
The second ratchet plate 12 is brought into close contact therewith. However, by pushing the knob 13 against the compression spring 14, the second ratchet plate 12 can be relatively rotated away from the first ratchet plate 10.

[0008] A wire winding drum 15 is rotatably provided on the outer periphery of the short tube portion 8. A wire 16 for adjusting the ball force is wound around the outer periphery of the wire winding drum 15, and the other end of the wire 16 is wound around a drum 18 of a handle 17. Also, the wire winding drum 15
The base end of a wound spring type ball spring 7 provided on the outer periphery of the short cylindrical portion 8 is fixed inside the base. The tip of the ball spring 7 is fixed to the second ratchet plate 12 described above. ing. For this reason, when the player operates the handle 17, the wire 16 is pulled, the wire winding drum 15 rotates, and the position of the base end of the ball spring 7 changes, so that the strength of the ball spring 7 is reduced. The ball force is adjusted to change.

In the above-configured ball-and-ball apparatus for a pachinko machine according to the present invention, the first ratchet plate 10 and the second ratchet plate 12 are always engaged with each other. Is changed to change the spring force, the spring force is transmitted from the second ratchet plate 12 via the first ratchet plate 10 to the rotary shaft 4 as it is, and the ball force adjustment is performed.

When the pachinko parlor wants to adjust the spring force, the knob 13 is pushed in against the compression spring 14 to rotate the second ratchet plate 12 away from the first ratchet plate 10 and relatively. As a result, the second ratchet plate
Since the relative angle between 12 and the first ratchet plate 10 changes, the spring force can be adjusted.

[0011]

As described above, in the ball-ball apparatus of the pachinko machine according to the present invention, the spring force can be adjusted in the same manner as the conventional ball-ball machine. Since it is provided coaxially with the rotation axis of the mallet, there is an advantage that the mounting space on the substrate can be reduced. Further, according to the present invention, the springs for the spheres directly connected to the wire winding drum via gears and wires do not need to be rotated as in the prior art, so that there are no parts attached to them and the product cost is reduced. There is an advantage that it can be reduced.
