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 which drives a ball-and-ball hammer linearly.

[0002]

2. Description of the Related Art As a ball-ball device of a pachinko machine of a type in which a ball-hammer is linearly driven, for example, Japanese Utility Model Laid-Open No. 4-90383.
Gazette, Japanese Utility Model Application Laid-Open No. 5-159, and Japanese Utility Model Application Laid-Open No. 7-1977.
As disclosed in Japanese Unexamined Patent Publication (Kokai) No. H10-209, there is known an apparatus in which a ball hammer is directly driven by a solenoid coil. However, in such a solenoid type ball-and-ball device, the magnetic force of the solenoid coil fluctuates due to a current change accompanying the voltage fluctuation of the hall,
There has been a problem that ball flying tends to vary. In addition, since the solenoid type ball device cannot basically adjust the ball force by the spring, there is a problem that the variation of the ball jump cannot be adjusted.

[0004] On the other hand, a ball-and-ball device of the type in which a ball cam is rotated by rotating a ball-and-ball cam with a motor that has been widely used in the past, even if the driving force of the motor slightly fluctuates due to the voltage fluctuation of the hole. Also, there is an advantage that the ball force itself is constant, and there is also an advantage that the ball force is easily adjusted by a spring. However, since the ball hammer requires a large space to perform a swiveling motion, and the tip of the ball hammer draws an arc,
There was a problem that it was not easy to adjust the capture of the ball so that it hit the center of the ball accurately.

[0005]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and does not cause variation in ball jump due to fluctuations in the voltage of the hole. Even if there is variation in ball jump, adjustment is easy and wide. The purpose of the present invention is to provide a ball-and-ball device for a pachinko machine that does not require space and that can easily adjust the capture of a ball.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a ball hammer guided so as to perform a linear motion, and a method in which the ball hammer is always linearly moved toward the ball. A spring for urging the ball and a roller fixed to the ball hammer
Arm with a motor and continuously rotated by a motor
The ball hammer engages the roller and compresses the ball spring.
And a ball- and- ball cam that repeats the operation of retracting and releasing. Hereinafter, preferred embodiments of the present invention will be described.

[0007]

1 and 2 show a first embodiment of the present invention. Reference numeral 1 denotes a ball hammer guided by guides 2 and 3 so as to perform only a linear motion. The guide 3 on the rear side (the side opposite to the tip of the ball hammer 1) is provided with a spring receiver 5 that can be moved forward and backward by an adjustment knob 4. A spring receiver 6 is also fixed to the center of the ball hammer 1, and a ball spring 7 is mounted between the spring receivers 5 and 6. The spring 7 for a ball and the spring receiver 6 always urge the ball hammer 1 linearly toward the ball.

The spring receiver 6 of the ball hammer 1 has an arm 8 extending downward, and a roller 9 is attached to the tip of the arm 8. The roller 9 is engaged with a ball cam 10 continuously rotated by a motor as in the prior art. Then, when the ball cam 10 is rotated clockwise from the state shown in FIG. 1, the ball hammer 1 retracts while compressing the ball spring 7 as shown in FIG. Then, when the ball cam 10 further rotates, the roller 9 is disengaged from the ball cam 10 and the ball hammer 1 is linearly advanced by the ball spring 7 to ball the ball 12 on the ball receiver 11. Repeat the operation.

Reference numeral 13 denotes a stopper rubber attached to the back surface of the guide 2, and reference numeral 14 denotes a wire for allowing the player to move the spring receiver 5 with respect to the guide 3 by operating the handle to adjust the ball force.

In the first embodiment, the ball cam 10 is continuously rotated by a motor and the arm 10 is fixed to the ball hammer 1 in the same manner as in the prior art.
In order to perform the ball movement by engaging with the roller 9 at the tip of
There is no variation in ball jump due to voltage fluctuations in the hall. Even if there is a variation in ball jump, the position of the spring receiver 5 can be moved by operating the adjustment knob 4 and the handle to easily adjust the ball force. Furthermore, since the ball hammer 1 is guided by the guides 2 and 3 so as to perform only a linear motion, there is an advantage that a wider space is not required than a revolving ball hammer and the catching of the ball is easily adjusted. .

FIGS. 3 and 4 show a second embodiment of the present invention, in which the spring receiver 5 is a spur gear. By rotating the drive gear 15 by operating the handle, the player moves the spring receiver 5 forward and backward, and can adjust the ball force of the ball spring 7. In the second embodiment, a rack 16 is mounted on the side of the ball hammer 1, and an intermittent gear 17 continuously rotated by a ball motor is provided on the rack 16.
I'm engaged. Since other configurations are the same as those of the first embodiment, corresponding portions are denoted by the same reference numerals and description thereof is omitted.

In the ball-ball apparatus according to the second embodiment, the intermittent gear 17 is continuously rotated by the motor to retreat the ball-hammer 1, and when the intermittent gear 17 is further rotated from the state shown in FIG. The ball hammer 1 linearly advances due to the ball force of the ball and repeats the operation of hitting the ball 12 on the ball receiver 11.

As in the first embodiment, the ball-and-ball device of the second embodiment has no variation in ball jump due to fluctuations in the voltage of the hole. Can be adjusted. In addition, since the ball hammer 1 is guided by the guides 2 and 3 so as to perform only linear motion, there is an advantage that it does not require a wider space than a revolving ball hammer and it is easy to adjust the catching of the ball. .

[0014]

As described above, the ball-and-ball apparatus for a pachinko machine according to the present invention can exhibit the advantage of the linear drive without impairing the advantage of the conventional motor-driven type.
It is a technically high value ballistic device that combines the advantages of both.
