DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition,
The same or equivalent parts as those in the conventional example will be described using the same reference numerals. In FIG. 1, a reference numeral 30 denotes an outer rotor type finite angle torquer having a configuration to be described later, and a hammer 8 is directly connected to the outer end 6a of the rotating shaft 6 of the outer rotor type finite angle torquer 30. , This hammer 8
Is a configuration to return to the original position by its own weight. The other configuration shown in FIG. 2 is configured such that the hammer 8 returns to the original position by the return spring 40.

The outer rotor type finite angle torquer 30 is
It is configured as shown in FIGS. In FIGS. 3 and 4, reference numeral 1 denotes a ring-shaped stator fixed to the mounting plate 2, and an exciting coil 4 is multi-staged in a ring-shaped groove 3 formed on the outer periphery of the ring-shaped stator 1. It is wound in line. The mounting plate 2 is fixed to the steps 100 and 101 of the annular stator 1. That is,
The mounting plate 2 is firmly fixed by engaging with the step portions 100 and 101 having different diameters.

A cavity 1 formed at the center of the stator 1
A rotating shaft 6 is rotatably provided in B through a pair of bearings 5. A rotating member 8 such as an arm or a hammer is provided on an outer end 6 a of the rotating shaft 6 via a nut 7. Has been fixed.

A cover 9 having a cup shape is provided integrally with the end 6b of the rotating shaft 6 so as to cover the annular stator 1. The inner wall 9a of the cover 9 is provided with a rotor 9 made of a magnetic material. A ring-shaped rotor 10 as a magnetic body is integrally fixed. The bearings 5 are arranged so as not to be located outside the end faces 1d and 1e in the axial direction of the annular stator 1.

As shown in FIG. 4, the outer periphery 1a of the stator 1 has a center-to-center spacing set to 120 degrees.
Stator teeth 1A are formed to protrude, and the rotor 1
The rotor teeth 10A of the same number as the stator teeth 1A and having the same number protrude from the inner circumference 10a of 0.

Therefore, in the above-described configuration, when the exciting coil 4 is excited, the rotor 10 and the cover 9 are within a predetermined angle range without rotating once through the magnetic path formed by the stator teeth 1A and the rotor teeth 10A. The hammer 8 provided on the rotating shaft 6 rotates against the spring force of the return spring stretched on the hammer 8 by this rotation, and the action of a hammer such as a pachinko for hitting a ball is performed. To achieve. Therefore, by turning off the excitation coil 4, the rotary shaft 6 returns to the original position via the spring, and by repeating this operation, high-speed driving can be performed.

As shown in FIGS. 5 and 6, the stator teeth 1A are projected, and the exciting coil 4 is projected from each end face 1C, 1D in the axial direction of the stator teeth 1A to form a salient pole winding. The same effect can be obtained when the cover 9 is formed by embedding a rotor portion 10E as a rotor magnetic body made of a magnetic material having the same effect as the rotor teeth 10A.

As shown in FIGS. 7 and 8, the same operation as that of the stator teeth 10A is performed on the stator 1 made of a nonmagnetic material in which the exciting coil 4 is bobbin wound around the bobbin 60 of the concave groove 3. 4, a stator portion 1E made of a magnetic material may be buried, and the rotor portion 10E may be buried in the cover 9 similarly to FIG. In addition, this stator tooth 1A,
An arbitrary angle and torque can be obtained by changing the number of the stator portion 1E, the rotor teeth 10A, and the rotor portion 10E from one to any number and shape.

[0021]

[Effect of the Invention] The present invention has the above-described configuration and operation, so that the following effects can be obtained.
That is, since the hammer is directly connected to the rotating shaft of the outer rotor type finite angle torquer including the stator and the magnetic member for the rotor, direct movement of the hammer can be obtained without using a conventional cam or the like, and the size of the pachinko launching device can be reduced. And cost reduction can be easily achieved. In the past, when a mechanism was used that fired pachinko balls with the magnetomotive force of a rotary solenoid without using a spring, the heat generated by the solenoid caused variations in torque, causing problems such as flying variations. Always fires the ball with the energy of the spring, so there is no variation in the flying of the ball.
