Description

[Detailed Description of the Invention] [Industrial Application Field 1] An object of the present invention is to provide a device for launching pachinko balls with a simple structure and circuit that can improve the accuracy of launching pachinko balls. shall be.

[Prior art 1] In the conventional electric pachinko ball firing device, the most traditional form is to rotate a motor with a clamp attached to the shaft, and use the clamp to rotate the firing hammer in the opposite direction to the firing direction. The hammer was fired using the force of a spring.

With this technology, as the hammer tip hits the pachinko ball as the hammer rotates, the hammer tip comes into contact with the pachinko ball at an angle (or ζ), and the angle also changes slightly, making it difficult to launch the ball. An unexpected force will be applied to the player.

This is extremely dissatisfying for players who aim to improve their skills and get good results in DEME.

[Problems to be Solved by the Invention] The present invention provides a pachinko ball firing device that solves the problem of firing accuracy in the prior art.

[Means for Solving the Problems J] In order to solve the above problems, the present invention solves this problem by eliminating the use of a hammer and setting the ball hitting axis coaxially with the firing direction to provide front and rear linear interlocking. solved.

A linear motor that can be linked in a straight line is used for this drive, and in order to comply with the administratively required regulation of the number of shots for pachinko machines, a device that generates electric power at a constant cycle is connected to this linear motor. The system was made to comply with the regulations as a means of supplying electricity.

[Example 1 The structure of the present invention will be explained along with examples.

FIG. 1 schematically shows the main parts of an example of a pachinko machine embodying the present invention.

Figure 2 A and B show the aspects of the ball hitting axis and spring.
Two embodiments are shown.

FIG. 3 is a diagram showing two means for generating periodic power.

Reference numeral 1 denotes a ball hitting shaft, which is attached to a linear motor 3 coaxially with the center axis of the pachinko ball 2 so as to be able to freely move forward and backward in a straight line.

A spring 4 is attached to a suitable location on the ball hitting shaft 1.

First, the operation will be explained with reference to FIG.

The linear motor 3 is supplied with electric power at a constant cycle from the electric power supply VC shown in FIG.

Now, when power is supplied from the power supply device, the force of the linear motor 3 overcomes the force of the spring 4, the ball hitting axis 1 returns to the firing standby position, and after a short period of time determined by the power supply device, the power is released. When it is disconnected, the force of the linear motor 3 disappears, and the force of the spring 4 causes the ball hitting axis to move straight toward the pachinko ball, causing the ball to be launched.

The firing strength can be adjusted by adjusting the tension of this spring.

It is desirable from the viewpoint of both longevity and firing accuracy to embed a hard ceramic in the tip of the ball-striking shaft 1 or to secure strength against collision with a pachinko ball.

It is desirable to provide the ball-hitting shaft 1 with an id, especially when it is desired to improve the accuracy of its position, but if there is no large play in the shaft of the linear motor 3, it is conceivable to connect it directly to the shaft as shown.

Further, the ball hitting shaft 1 can also be used as the ball hitting shaft 1 by machining or extending the shaft of the linear motor 3.

An example of this was shown to the second painter.

In this case, it is also possible to set the spring in the opposite direction to the direction in which the pachinko balls are launched.

By the way, some linear motors produce a large resistance to the tension of the spring even when the power is turned off.

In such a case, it may be possible to reduce this resistance by providing a mechanism having a latch function in the middle as shown in FIG. 2B.

In the case of FIG. 2B, in order to recover the ball hitting axis from the position where it was once fired, it is necessary to apply a current to the linear motor 3 so that it operates in the opposite direction.

Note that it is most desirable for the linear motor used here to be linearly interlocked from the beginning, but it is also possible to use a linear motor whose shafts are linearly interlocked by converting the rotation internally.

If the shaft were to rotate, additional means would be required externally to convert rotation into linear motion.

In general, if currently available solenoid coils are used for such purposes, they are considered to be inferior to linear motors in terms of the force they can generate and the accuracy of that force. If so, the linear motor 3 could be replaced with a solenoid coil instead, and the linear motor of the present invention is not intended to exclude such a solenoid fill.

Next, a constant cycle power supply device will be explained.

A suitable DC power supply 10 and AC motor 11 are provided.

The rotation of this AC motor 11 is caused by the brush 12 and the commutator 1.
3, and the current from the DC power supply is interrupted at regular intervals.

This current is supplied to the linear motor.

If this current is also supplied to the opening and closing of the gate of the pachinko ball dropping device at the same time, the timing at which the pachinko balls fall and the timing at which the balls are fired by the spring can be synchronized within an appropriate range, making it even more convenient. .

AC motors have the advantage of being highly stable and unaffected by noise as a means of easily ensuring a constant cycle.

Another method is to obtain a constant periodic current using an electronic device.

This method uses a crystal oscillator or other oscillator 14 to obtain a signal with a constant period, and converts this signal into desired power using a semiconductor amplifier 15 or other means.

In this case, a more stable period can be obtained with less power consumption, but it is fundamentally weak against noise and the like.

Detailed Description of the Invention As explained in detail, the present invention uses a linear force to shoot a pachinko ball, whereas the conventional method uses a rotational force to shoot a pachinko ball. force can be applied as is.

Therefore, the accuracy of firing is increased, and the player can play the game according to his/her skill.

Additionally, equipment manufacturers can easily manufacture equipment with high firing accuracy, and there is no need for delicate adjustments to align the hammer tip with the center of the pachinko ball, or it can be done easily.
