Abstract

PURPOSE:To solve that a ball once shot is discharged and again returned, and prevent a shooting failure by arranging a ball moving rail consisting of nonmagnetic body as a guide means between opposed magnetic poles, and forming a ball discharging notch closer to the ball shooting direction from the ball waiting CONSTITUTION:When a handle 13 is operated to rotate an angle sensor 14 by a prescribed angle, a controller 10 carries a current to a plurality of coils 8a, 9a on the basis of this rotation signal. Since magnetic forces are thus generated in a plurality of electromagnets 8, 9 to carry a magnetic flux between the respective magnetic poles 8b, 9b, a prescribed magnetic field is formed. Since a magnetic force consequently acts on a ball 7 supplied one by one from a ball supplying passage to the rail 12, the ball 7 is traveled toward between the magnetic poles 8b, 9b and shot. In this case, the rail 12 is formed with an inclination from a rail part 12 and a guide part 12b, and a discharging notch 12c is formed on a part of the guide part 12b. The following ball 7a is made to collide with the waiting ball 7, and discharged from the discharging notch 12c.

Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art FIG. 5 shows a conventional ball launching device for a game machine. As shown in FIG. 5, first and second coils 2 and 3 are wound on both sides of a yoke 1 having a square V-shape, and magnetic poles 4 and 5 facing each other.
The sphere 6 was guided between them, and the sphere 6 was fired by the magnetic force generated between the magnetic poles 4 and 5.

[0003]

Although not shown, the ball 6 is guided between the magnetic poles 4 and 5 by a rail, and is also guided by the rail to be fired forward.

In the pachinko machine, if the amount of operation of the handle is small, the ball 6 does not reach the game part, and is reversed from the middle of the rail to return to the magnetic poles 4 and 5.

Since the sphere 6 that emits a magnetic force has a small emission force, when the sphere 6 returns as described above and the next supplied sphere 7 and two spheres are located between the magnetic poles 4 and 5, the sphere 7 There was a problem that could not be fired.

Therefore, the present invention has an object to prevent occurrence of a non-firing state of a ball by preventing the ball once fired from returning to between magnetic poles again.

[0007]

In order to achieve this object, the present invention provides a ball discharge notch in the ball firing direction from the standby position of the ball on the rail.

[0008]

With the above construction, the ball returning to the magnetic pole portion after being discharged is discharged from the rail through the discharge notch, so that the ball cannot be discharged. Of.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be explained. In FIGS. 1 and 2, 7 is a ball such as a pachinko ball made of a magnetic material. Reference numerals 8 and 9 denote first and second electromagnets for generating magnetic force, which have first and second coils 8a and 9a, respectively, and currents supplied to these first and second coils 8a and 9a. The value is controlled via the controller 10. Reference numeral 11 is a U-shaped yoke made of a magnetic material.
The magnetic path of the second electromagnets 8 and 9 is formed.

The opposing magnetic poles 8b of the first and second electromagnets 8 and 9 are different from the S pole and 9b is different from the N pole. Reference numeral 12 is a rail made of non-magnetic material such as stainless steel, and is provided between the opposing magnetic poles 8b and 9b so as to smoothly strike the ball 7 in a predetermined direction. Reference numeral 13 is a handle operated by the player, and the angle sensor 14 mechanically interlocked transmits the rotation angle to the controller 10. If the rotation angle is large, the current supplied to the first and second coils 8a and 9a is increased. It is designed to increase the value.

That is, when the player (operator) rotates the angle sensor 14 through the handle 13 in such a configuration by a predetermined angle, a signal corresponding to the rotation angle is transmitted to the controller 10 and the signal is transmitted. Based on this, the value of the current supplied from the controller 10 to the first and second coils 8a and 9a is determined. Due to this energization, a magnetic force is generated in the first and second electromagnets 8 and 9, which causes a magnetic flux to flow from the magnetic pole 9b of the second electromagnet 9 to the magnetic pole 8b of the first electromagnet 8, whereby the a line in FIG. A magnetic field is generated like. As a result, the rails 12 are supplied one by one to the balls 7 in the standby position as shown in FIG.
The magnetic force works like the b line. As a result, the ball 7 is on the rail 12
Toward the space between the magnetic poles 8b and 9b, and the sphere 7 moves toward the magnetic poles 8b and 9b.
When reaching the center of 9b, the first and second coils 8a,
The power supply to 9a is cut off by the controller 10. Then, the ball 7 travels on the rail 12 to the left in FIG. 1 by inertia and is launched. The line c in FIG. 2 shows the ball speed, and the line d shows the current supplied to the first and second coils 8a and 9a.

3 and 4 show a portion of the rail 12 in which the opposing magnetic poles 8b and 9b are diagonally opposed.
In this state, the rail 12 is installed between the magnetic poles 8b and 9b. More specifically, the rail 12 includes the rail portion 12a and the guide portion 1 provided on the side of the rail portion 12a.
And 2b.

The rail portion 12a is installed on the magnetic pole 9b. The guide portion 12b is 14 times larger than the rail portion 12a.
It is provided in an open angle of 4 degrees. Also rail part 1
2a itself is also installed with an inclination of 18 degrees upward with respect to the horizontal plane.

The position of the ball 7 on the right side of FIGS. 1 and 4 is the standby position, and the left end of the rail 12 is inclined upward by 20 to 25 degrees.

The guide portion 12b in the firing direction of the ball 7 at the standby position of the ball 7 has a diameter 14 larger than 11 mm.
A notch 12c for discharge of mm is provided.

In this state, when the sphere 7 is fired by a magnetic force as shown in FIG. 1, the sphere 7 slides on the rail portion 12a while receiving the attraction force to the magnetic pole 9b side by the magnetic force. It is not discharged from the cutout 12c.

However, the above-mentioned suction force is not generated on the ball 7a which has been weakly fired and returned after being fired once,
Since the rail portion 12a is inclined by 18 degrees, the rail portion 12a returns while contacting the guide portion 12b, and is discharged from the discharge notch 12c as shown in FIG.

Therefore, it does not collide with the ball 7 waiting as shown in FIG.

[0019]

As described above, according to the present invention, the ball discharge notch is provided in the ball launching direction from the standby position of the ball on the rail. With the above configuration, the ball returns to the magnetic pole portion after launching. Since the ball that has come back is discharged from the rail through the discharge notch, the ball cannot be fired.
