DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, as a pachinko ball firing device, there has been a system in which a spring is pulled by a motor to hit a ball hitting member in a gap, and a system in which a hammer is hit by a rotary solenoid in a gap.

[0003]

In the above prior art, a ball hitting member uses a heavy ball hitting member because the force for hitting the ball is greatly affected by a change in the rotation angle of the ball hitting member. However, there is a problem that it is difficult to fine-tune the firing speed and the firing of the ball becomes unstable. Further, since the means for returning the ball striking member to the initial drive position is performed by the elasticity 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. An object of the present invention is to solve the above problems.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a ball striking rod at the rear end of a firing rail.
The ball striking rod is disposed so as to slide linearly with respect to the center.
A swinging rod is provided at the rear to be swingable, and the swinging rod is
The ball hitting rod slides and fires
It is characterized by hitting the ball center of the rail .

1 and 2 show a first embodiment of the present invention. 1
Is a ball firing rail of a pachinko machine, in which a ball striking member 3 is disposed in a rear end housing 2 so as to be able to move back and forth, and a spring 4 constantly biases a flange 3a in the middle of the ball striking member 3 to a rearward position. Striking member 3
The tip protrudes from the rear end of the ball firing rail 1. Reference numeral 5 denotes a hammering rod, the intermediate portion of which is pivotally connected to a shaft 6 so as to be swingable, and the tip of the rod 5 is disposed so as to abut the rear end of the ball hitting member 3;
An electromagnet 7 is arranged facing 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 front end of the striking rod 5. Reference numeral 10 denotes a stopper at the forward position of the striking rod 5, and reference numeral 11 denotes a stopper at the retracted position of the striking rod 5.

Next, the operation will be described. When the striking rod 5 is not actuated, the leading end abuts on the retreat position stopper 11, and the lower end magnet 8 repels the leading end of the electromagnet 7 to keep a predetermined distance. When the electromagnet 7 is excited in this state, the magnet 8 at the lower end of the striking rod 5 becomes as shown in FIG.
, The tip of the hitting rod 5 rotates forward and hits the rear end of the ball hitting member 3. The ball hitting member 3 fires a ball 12 located at the tip of the ball hitting 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 the position by the attractive force of the magnet 8. next,
When the voltage applied to the electromagnet 7 is reversed to be excited, the S and N poles of the magnetic force generated in the electromagnet 7 are switched, and the magnet 8 is switched.
And the tip of the electromagnet 7 repels and returns to the original state. Electromagnet 7
, And the above operation is repeated. FIG. 5 is a time chart of the voltage applied to the electromagnet. The firing voltage changes from 12V to 24V depending on the strength of the steering wheel. In addition, it is possible to control the striking force and the operation time by supplying a small residual current to the coil of the electromagnet when the coil is turned off.

FIGS. 3 and 4 show a second embodiment of the present invention.
The configuration of the ball firing rail is the same as in the first embodiment. Fifteen
Is a striking rod, the intermediate portion of which is pivotally connected to the shaft 16 so as to be freely swingable, and the tip of the striking rod 15 is disposed so as to contact the rear end of the ball striking member 3. Electromagnets 17 and 18 are disposed on both sides of the trailing end of the striking rod 15 so as to face each other.
9 is fixed, and a hard rubber roller 20 is fixed to the tip of the striking rod 15. Reference numeral 21 denotes a retracting position stopper of the hitting rod 15.

Next, the operation will be described. When the striking rod 15 is not actuated, its tip abuts against the retreat position stopper 21, and the lower end magnet 19 attracts the left electromagnet 18 and repels the right electromagnet 17 at the same time to maintain a predetermined interval. When the electromagnets 17 and 18 are excited in this state, the magnet 19 is attracted by the electromagnet 17 as shown in FIG.
Rotates forward and strikes the rear end of the ball striking member 3.
The ball hitting member 3 fires a ball 12 located at the tip of the ball hitting member 3 against the elasticity of the spring 4. Electromagnet 17,
When the switch 18 is turned off, the electromagnets 17 and 18 become iron pieces and maintain their positions by the attractive force of the magnet 19. Next, the electromagnets 17 and 18
When the magnets are excited by reversing + and-of the voltage applied to
The S and N poles of the magnetic force generated in the magnets 7 and 18 are switched, and the magnet 19 is attracted to the electromagnet 18, and at the same time, rebounds with the electromagnet 17 and returns to the original state. The 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 that in FIG. Note that a ball hitting member may be attached to the tip of the hitting 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 hitting member can be easily finely adjusted by increasing and decreasing the electromagnet reference voltage. Also, as shown in FIG. 7, the speed of the ball can be adjusted by adjusting the distance between the electromagnets.

[0010]

According to the present invention , a ball is hit at the rear end of the firing rail.
The firing rod slides linearly about the ball center of the firing rail.
And the swinging rod is swingably arranged behind the ball hitting rod.
Then, the swinging rod is attracted and repelled by a magnet,
Since the ball hitting rod slides to hit the ball center of the firing rail, fine adjustment of the firing speed can be easily performed by adjusting the voltage of the electromagnet and adjusting the distance between the electromagnet and the magnet.
