Abstract

PURPOSE:To stably launch a ball for pinball game (pachinko) by pivotally connecting a hit lever at an intermediate part in such a way that it can be freely rocked, arranging the tip of the hit lever advancing the ball launching position of a ball launching rail so as to be driven, mounting a magnet on the other terminal and driving the hit lever by attraction/repulsion between the magnet and an electromagnet arranged confronting with the magnet. CONSTITUTION:The intermediate part of the hit lever 5 is pivotally connected by shaft 6 such a way that it can be freely rocked, and a hard rubber roller 9 is fixed on the tip of the hit lever 5. While, a ball batting part 3 is provided by facing its tip with the ball launching rail 1. The ball batting part 3 is housed in a cabinet 2, and is always energized rearward by a spring 4. Also, the rear end of the batting part 3 is abutted on the hard rubber roller 9 of the hit lever 5. The magnet 8 is mounted on the other end of the hit lever 5, and the electromagnet 7 is arranged at a position confronting with the magnet 8. The hit lever 5 is rocked by exciting the electromagnet 7 and attracting the magnet 8, and the ball batting member 3 is moved forward, then, the ball 12 can be batted. Also, the main batting part 3 is returned to an original position by the force of the spring 4 by exciting the electromagnet 7 in an opposite direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball launching device.

[0002]

2. Description of the Related Art Conventionally, as a pachinko ball launching device, there are a system in which a spring is pulled by a motor to hit the ball striking member in a gap, and a system in which a mallet is hit by a rotary solenoid.

[0003]

In the above-mentioned prior art, since the force for hitting a ball is greatly affected by the change in the rotation angle of the ball hitting member, a heavy ball hitting member is used and a pachinko ball is hit by hitting inertial weight. Since it was firing, it was difficult to fine-tune the firing speed and the ball firing became unstable. Also, since the ball striking member is returned to the initial driving position by the elastic force of the spring, it cannot be adjusted. Further, the method using a motor has a problem that the number of balls to be fired changes depending on the frequency, the motor temperature, the strength of the spring, and the like. The present invention aims to solve the above problems.

[0004]

In order to achieve the above-mentioned object, the present invention is capable of swingably pivoting an intermediate portion of a batting rod and driving the tip of the batting rod toward a ball firing position of a ball firing rail. The magnet is fixed to the striking rod, the electromagnet is arranged so as to face the operating position of the magnet, and the striking rod is driven by attraction and repulsion between the magnet fixed to the striking rod and the electromagnet. It is characterized by doing so.

Is a ball launching rail of a pachinko machine, in which a ball striking member 3 is movably arranged back and forth inside a housing 2 at a rear end, and a spring 4 constantly urges a collar 3a in the middle of the ball striking member 3 backward. Striking member 3
The tip projects from the rear end of the ball firing rail 1. 5 is a hammer striking rod, the middle portion of which is swingably pivoted about a shaft 6 and is arranged so that the tip of the striking rod 5 abuts the rear end of the ball striking member 3.
An electromagnet 7 is arranged so as to face the operating position of the rear end of the striking rod 5, a magnet 8 is fixed to the rear end of the striking rod 5, and a hard rubber roller 9 is fixed to the tip of the striking rod 5. Reference numeral 10 is a stopper at the advance position of the hitting rod 5, and 11 is a stopper at the retracted position of the hitting rod 5.

Next, the operation will be described. The tip of the striking rod 5 abuts the retracted position stopper 11 when not operating, and the lower end magnet 8 repels the tip of the electromagnet 7 and maintains a predetermined distance. When the electromagnet 7 is excited in this state, the magnet 8 at the lower end of the striking rod 5 is
As described above, the tip of the striking rod 5 is swung forward by the electromagnet 7 and strikes the rear end of the ball striking member 3. The ball striking member 3 shoots the ball 12 located at the tip of the ball striking member 3 against the elasticity of the spring 4. When the electromagnet 7 is turned off, the electromagnet 7
Becomes an iron piece and holds its position by the attractive force of the magnet 8. next,
When + and − of the voltage applied to the electromagnet 7 are reversed and excited, the S pole and N pole of the magnetic force generated in the electromagnet 7 are switched and the magnet 8 is replaced.
And the tip of the electromagnet 7 repels and returns to the original state. Electromagnet 7
The above operation is repeated by repeating excitation, off, reverse excitation, and off. FIG. 5 is a time chart of the voltage applied to the electromagnet. The firing voltage varies from 12V to 24V depending on the strength of the handle. In addition, it is possible to control the striking force and the operating time by passing a small residual current to the coil of the electromagnet when the coil is off.

FIGS. 3 and 4 show a second embodiment of the present invention.
The structure of the ball launch rail portion is the same as that of the first embodiment. 15
Is a striking rod, the middle portion of which is pivotally attached by a shaft 16 so that the tip of the striking rod 15 abuts the rear end of the ball striking member 3, and the rear end of the striking rod 15 is rotated. Electromagnets 17 and 18 are arranged on both sides of the trailing end of the striking rod 15 on the locus so as to face each other and the magnet 1
9 is fixed, and the hard rubber roller 20 is fixed to the tip of the striking rod 15. Reference numeral 21 is a retracted position stopper of the striking rod 15.

Next, the operation will be described. The tip of the striking rod 15 contacts the retracted position stopper 21 when it is not operated, and the lower end magnet 19 attracts the left electromagnet 18 and at the same time repels the right electromagnet 17 to keep a predetermined distance. When the electromagnets 17 and 18 are excited in this state, the magnet 19 is attracted by the electromagnet 17 as shown in FIG.
Of the ball hits the rear end of the ball hitting member 3.
The ball striking member 3 shoots the ball 12 located at the tip of the ball striking member 3 against the elasticity of the spring 4. Electromagnet 17,
When 18 is turned off, the electromagnets 17, 18 become iron pieces and hold their positions by the attractive force of the magnet 19. Next, the electromagnets 17, 18
When the + and-voltages applied to the
The S and N poles of the magnetic forces generated in the magnets 7 and 18 are exchanged, and the magnet 19 is attracted to the electromagnet 18, and at the same time repels the electromagnet 17 and returns to the original state. Excitation, OFF, reverse excitation, and OFF of the electromagnets 17 and 18 are repeated, and the above operation is repeated. The electrical time chart at this time is the same as in FIG. A ball striking member may be attached to the tip of the striking rod to directly hit the ball located at the firing position of the firing rail.

As shown in FIG. 6, the firing speed of the ball striking member can be easily finely adjusted by raising or lowering the electromagnet reference voltage. Further, as shown in FIG. 7, the speed of the ball can be adjusted by adjusting the distance between the electromagnet and the magnet.
