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 for a pachinko machine.

[0002]

2. Description of the Related Art A conventional pachinko ball launching device will be described with reference to FIG. The arm 1 installed so as to be freely rotatable by the bearing 2 has a return spring 7 attached to a part thereof.
It stops by contacting the stopper 6 due to the tension caused by. A cam 3 is attached to the output shaft of the motor 4, and the roller 5 installed on a part of the arm 1 by rotating.
Contact with. Since the shape of this cam rotates, the arm 1 is gradually rotated in the direction of the arrow against the tension of the spring 7. The cam 3 has a shape in which the diameter suddenly decreases on the way, and the arm 1 returns to the position where it comes into contact with the stopper 6 by the tension of the return spring 7. At this time, the pachinko ball 9 is supported on the rail 10 and is in the position shown in the figure, so that the pachinko ball 9 is hit by the striking portion at the tip of the arm 1 and is fired in the arrow direction. Further, by rotating the drum 8, the tension of the return spring can be varied and the striking force can be varied. Since this method hits a pachinko ball directly, the hitting force changes due to the striking force at the tip of the arm 1, wear of the cam, change in the strength of the return spring, etc., so periodic maintenance is required. Further, there is a drawback that the noise is generated because it is hit directly.

Further, in the linear motor type launching device shown in FIG. 12, a plurality of magnetic coils 11 are arranged on the outer periphery of the launching barrel 12, and the pachinko ball 9 placed at the position shown in the drawing is
A suction force is applied by energizing a coil arranged on the side closer to this, and the pachinko balls 9 are attracted by the magnetic force exerted in the firing barrel 12 and sent out in the direction of the arrow, and sequentially as the pachinko balls 9 move. It is accelerated and fired by switching the energized coil.

[0004]

By the way, in this method, the change in the striking force due to wear, deterioration of the return spring, etc. is solved by firing the pachinko balls in a non-contact manner, but control of a plurality of magnetic coils is extremely difficult. Is complicated. Especially when an attempt is made to change the hitting force, the speed of the ball naturally changes, so that the passage timing of each coil also changes. Therefore, it is necessary to change all the power supply timings to the respective coils, and in some cases it is necessary to change the drive voltage to the respective coils. Further, although a copper wire is used for the coil winding, when the temperature changes due to energization or the like, the direct current resistance also changes according to the temperature coefficient of the copper wire, and the resistance value rises as the temperature rises. If the resistance value increases, the current decreases. As is generally known, the magnetic force generated by the coils is proportional to the current, so it is necessary to keep the current to each coil constant in order to stabilize the striking force, and drive the control mechanism for this. The circuit will need to be considered.

Further, according to this method, when two or more balls are mistakenly replenished at the time of supplying pachinko balls, the surplus balls may receive a force in the direction opposite to the firing direction depending on the driving method or structure. , It may collide with each other internally, making it impossible to fire. Therefore, there is a problem that a mechanism for discharging the surplus balls is absolutely necessary.

In view of the above, the present invention utilizes the fact that the pachinko balls are magnetic so that the pachinko balls can directly utilize the force for firing the non-contact magnetic force to cause the problem of the conventional pachinko ball launching device. In order to improve the points and improve the ability, the aim is to achieve long life and hitting ability with a simple structure.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The first invention of the present case will be described with reference to FIGS. FIG. 1 shows a launcher body provided at the base end of a launch rail in a pachinko machine (not shown). In this launcher main body, a cylindrical launch barrel 100 into which a pachinko ball 101 can be loaded is made of a non-magnetic material such as brass, and a magnetic coil L is wound around a holder 107 on the outer periphery thereof. Reference numeral 109 is a stopper fitted to one end of the firing barrel 100.

On the other hand, FIG. 2 shows a circuit diagram of a pachinko ball launching apparatus according to the present invention, in which 102 is an oscillation circuit and 103 is a circuit.
Is a pulse width control circuit, and 104 is a drive circuit. The oscillation circuit 102 includes an oscillator OSC based on a reference oscillator X1 such as crystal or ceramics, a frequency divider DV that divides the output pulse signal of the oscillator OSC, and a touch switch TS. The touch switch TS is the front surface of the pachinko machine. The player turns on by touching a handle (not shown) provided on the. Further, the frequency divider DV divides the output pulse signal of the oscillator OSC so as to output the pulse signal 100 times per minute.

In the pulse width control circuit 103, the time setting variable resistor VR and the timing capacitor CT are connected to the timer integrated circuit 1C, and the output time is determined by this. The timer integrated circuit 1C operates at a constant voltage from the power supply terminal V1 via the constant voltage diode Z1. The time setting variable resistor VR can be arbitrarily changed by operating a handle provided on the front surface of the pachinko machine.

Further, the drive circuit 104 has three transistors Q1, Q2, Q at the output stage of the pulse width control circuit 103.
3 is connected to form an amplifier circuit, and a diode D1, a resistor R1, and a magnetic coil L are connected in series to a DC power supply terminal V2 so as to be switched by a transistor Q3 at the final stage. A large capacity capacitor C is connected in parallel to the series circuit of the magnetic coil L and the transistor Q3. Z2 is a constant voltage diode connected in parallel with the large capacity capacitor C. Further, Z3 is a constant voltage diode provided for preventing the destruction of the transistor Q3.

Therefore, when the timer integrated circuit IC receives a pulse signal having a period of 0.6 seconds as shown in FIG. 3A from the oscillator circuit 102, the timer integrated circuit IC is set in accordance with the setting of the time setting variable resistor VR. As illustrated in (b), (c) and (d), the pulse width W is continuously changed. Therefore, the transistors Q1 and Q provided in the output stage of the timer integrated circuit IC
The pulse signal is amplified by 2 and the transistor Q3 is turned on according to the input pulse signal. A current flowing from the power supply terminal V2 is stored in the large-capacity capacitor C, and when the transistor Q3 is turned on, the current flows to the magnetic coil L in a timed manner according to the pulse width of the pulse signal.
Therefore, the magnetic coil L is excited and its magnetic field is emitted from the firing cylinder 100.
By acting most strongly on the immediately preceding portion of the pachinko ball 101, the pachinko ball 101 is attracted by its magnetic force and is fired in the direction of the arrow.

FIG. 4 shows the relationship between the energization time to the magnetic coil L and the flight distance of the pachinko ball 101. In this way, the flight distance of the pachinko ball 101 increases as the energization time becomes longer, but it decreases conversely after a certain time. Therefore, it is possible to freely extend to the apex by increasing the energization time, that is, the pulse width W by operating the handle.

The launcher main body shown in FIG. 5 is provided with a yoke 110 surrounding the magnetic coil L on the outer circumference of the launch barrel 100, and the magnetic lines of force of the magnetic coil L are guided by the yoke 110 and enter the launch barrel 100. It is made easier. Also,
6 and 7, the magnetic coil L is provided outside the firing cylinder 100 so that both ends of a C-shaped iron core 111 inserted into the magnetic coil L are opposed to both sides of the firing cylinder 100. In this case, the magnetic lines of force are guided by the iron core 111 and are orthogonal to the launch tube 100. Further, in the launching device main body shown in FIG. 8, both ends 113 and 114 of the iron core 112 of the magnetic coil L are arranged so as to surround the outer circumference of the launching barrel 100. Magnetic field lines parallel to the axial direction can be formed. As described above, the launching device main body can take various forms.

On the other hand, FIG. 9 shows a circuit diagram of a pachinko ball launching apparatus according to the second aspect of the present invention, in which 102 is an oscillation circuit, 105 is a storage voltage control circuit, and 104 is a drive circuit. The oscillator circuit 102 includes an oscillator OSC, a frequency divider DV, and a touch switch TS, as in FIG.

The storage voltage control circuit 105 includes a variable voltage shunt regulator Q4, and a variable resistor RV and a resistor R connected to the R terminal of the shunt regulator Q4.
It consists of a voltage divider made up of R5 and R6 and an amplifier made up of transistors Q1 and Q2. VS is a DC power supply terminal. In the drive circuit 104, the magnetic coil L is connected in series with the transistors Q1 and Q3, and the large capacity capacitor C is connected to the primary side of the magnetic coil L. Z3 is a constant voltage diode for preventing the destruction of the transistor Q3.

In this circuit, however, the voltage applied to the large capacity capacitor C via the transistor Q1 can be controlled according to the value of the variable resistor VR which can be set by operating the handle provided on the front surface of the pachinko machine. The stored voltage of the large capacity capacitor C can be arbitrarily set by the handle. Then, when the transistor Q3 is turned on by receiving a pulse signal having a period of 0.6 seconds from the oscillator circuit 102, the current stored in the large capacity capacitor C flows in the magnetic coil L,
The magnetic coil L is excited to magnetically attract the pachinko ball 101 in the launch tube 100 to launch it. Large capacity capacitor C
Since a large amount of current flows into the magnetic coil L at a time as the storage voltage of is higher, the flight distance of the pachinko ball 101 is extended. FIG.
A graph showing the relationship between the storage voltage and the flight distance is shown in FIG.
In this way, the flight distance of the pachinko ball 101 extends substantially in proportion to the voltage, so that the desired ball can be shot by adjusting the variable resistor VR to an appropriate value by operating the handle.

[0020]

As described above, according to the pachinko ball launching device of the present invention, the current flowing from the large-capacity capacitor to the magnetic coil can be controlled by operating the handle, and the magnetic force applied to the pachinko ball is adjusted to allow the pachinko ball to travel freely. It has the advantages of being able to be controlled in a simple manner and having a simple structure.
