Was firing. Further, in a well-known finite angle torquer for a pachinko launcher using a VR (variable reluctance) type step motor, the pachinko ball is fired by rotating the VR type step motor within a predetermined finite angle.

[0003]

The conventional finite angle torquer for a pachinko launcher was constructed as described above.
The following issues existed. That is, the motor used for this type of torquer is provided with a large number of pole teeth over the entire circumference of the rotor, and a ring-shaped stator provided to surround the rotor is provided with a large number of pole teeth over the entire circumference. Therefore, it is difficult to reduce the size of the motor itself and the size of the launcher itself.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and more particularly, to provide a finite angle torquer for a pachinko projectile which has reduced cost and size by reducing the size of a motor. With the goal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a finite angle torquer for a pachinko projectile according to the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1, in the finite angle torquer for a pachinko launcher according to the present invention, the one denoted by reference numeral 1 is an arc-shaped yoke 1A and a pair of stator poles extending along both ends in a radial direction from both ends thereof. A stator 1 includes teeth 1B and 1C, and a coil 2 is wound around the stator 1.

On the other hand, a rotor 3 made of a magnetic material has a rotating shaft 3
A pair of rotor pole teeth 3B and 3C are provided rotatably about A and provided at positions corresponding to the pair of stator pole teeth 1B and 1C. A hammer 4 for hitting a pachinko ball 8 is provided on the rotating shaft 3A.
When no current is supplied to the coil 2 and the coil 2 is demagnetized, the hammer 4 is supported by the stopper 5 at the stationary position shown in FIG. In addition, as shown in FIG. 2, the rotating shaft 3 </ b> A is supported by a case 6 via a bearing 7.

In such a finite angle torquer for a pachinko launcher, when the coil 2 is demagnetized, the hammer 4 is supported by the stopper 5 as shown in FIG. 2 is excited, a magnetic field is generated in the stator 1 and the stator pole teeth 1B, 1
Since an N pole or an S pole is generated at C, as shown in FIG. 3, the rotor pole teeth 3B, 3C of the rotor 3 face the stator pole teeth 1B, 1C clockwise as shown in FIG. Is rotated by the finite angle θ in the direction of. When the coil 2 is demagnetized, the rotor 3 rotates by a finite angle θ in the counterclockwise direction in the figure due to the weight of the hammer 4, and the hammer 4 is supported by the rubber stopper 5 as shown in FIG. At the rest position, the rotor 3 stands still. Therefore, the excitation of coil 2 /
If the demagnetization is repeatedly performed, the pachinko balls 8 can be continuously fired by the hammer 4. By making the intensity of this current variable, the rotation speed of the hammer 4 can be made variable and the strength of hitting a pachinko ball can be changed.

According to the finite angle torquer for a pachinko launcher according to the present invention, it is not necessary to form the stator 1 in a ring shape and to provide a large number of pole teeth, and the stator 1 is formed into a fan shape including the operating angle θ of the hammer 4. Since it is possible to reduce the size by configuring the present invention, it is possible to provide a finite angle torquer for a pachinko launcher that is reduced in size and weight and has a reduced number of pole teeth to reduce the cost.
