Abstract

PURPOSE:To easily manufacture the joy stick, equipped with a noncontact angle sensor using a magnetoelectric transducing element, at low cost. CONSTITUTION:The joy stick is provided with an operation rod 2 on its base 1 in a tiltable state and detects the rotation of gimbals 3 and 4, etc., by an angle detector. The angle detector 10 consists of the magnetoelectric transducing element 21 which detects variation of the magnetic field produced by a permanent magnet 24 and angle varying plates 22 and 23 made of magnetic materials such as soft iron which rotate together with the gimbals. Arcuate through holes 25 and 26 through which magnetic flux does not pass are formed in the angle varying plates 22 and 23 so that parts overlapping with the magneto-resistance element 21 change as the angle varying plates 22 and 23 rotate. The gimbals 3 and 4 rotate by the slanting of the operation rod 2, the resistance value of the magneto-resistance element 21 varies with the positions of the through holes which do not pass the magnetic flux, and the angles of the gimbals, etc., are precisely detected without contacting.

SUMMARY OF THE INVENTION According to the present invention, an operating rod is tiltably provided on a base body, and an angle detector detects the rotation of a member (eg, gimbal) which rotates about a fulcrum by the tilting of the operating rod. With the joystick
The angle detector includes a permanent magnet, a magnetoelectric conversion element (magnetoresistive element or Hall element) capable of detecting a change in magnetic field from the permanent magnet, and a bending plate made of a magnetic material that rotates together with the rotating member. And a through hole through which magnetic flux does not pass is formed in a portion of the variable angle plate facing the magnetoelectric conversion element, and a hole position of a portion which is continuous in the turning direction of the variable angle plate and overlaps the magnetoresistive element It is formed so as to change with the rotation of the plate. The permanent magnet, the magnetoresistive element, and the bending plate are arranged inside the device base. For example, if the operating rod is a one-axis joystick that can only move one-dimensionally, the gonio-angle plate is attached to a member such as a support shaft that rotatably attaches the joystick to the base body. If the operation rod is a two-axis joystick that can be operated two-dimensionally in the front / rear / left / right directions, the angle changing plates are attached to the X-axis gimbal and the Y-axis gimbal so as to be integrally rotatable.

When the operating rod is tilted for operation or input, the bending plate rotates together with a member such as a gimbal, and the position of the portion of the through hole formed in the bending plate that overlaps the magnetoelectric conversion element changes. .. Since the magnetic flux from the permanent magnet passes through the bending plate portion of the magnetic material and does not pass through the through hole, the through hole whose position changes changes the magnetic flux passing through the magnetoelectric conversion element and changes the resistance value. Due to this change in the resistance value, the rotational position of the member such as the gimbal, that is, the tilted position of the operating rod can be accurately detected without contact.

It is formed so as to increase and decrease linearly. The magnetic flux from the permanent magnet 24 passes through the bending plate portion having a high magnetic permeability and passes through the through hole 2

The angle can be detected with high accuracy in the same manner as in the case of the conventional method using the arc-shaped yoke 103 shown in FIG. Further, the angle sensors 19 and 20 can be arranged in the base body 1, and the space for mounting the joystick can be reduced. Further, according to the present invention, the bending plates 22 and 23 having the through holes 25 can be produced only by punching a magnetic material plate with a press or the like, and compared with the conventional method in which two members having different materials and shapes are assembled. Therefore, the production cost can be greatly reduced and the production work can be easily performed.

Although the two-axis joystick has been described above, it is needless to say that the present invention can be applied to a one-axis joystick in which the operating rod is operated only in one direction. In this case, the bending plate is attached to the support shaft that tiltably supports the operation rod. Further, although the permanent magnet and the magnetoresistive element are installed on the fixed side, it is also possible to dispose them on the movable side such as a gimbal and form the through hole on the base side. Further, it goes without saying that the present invention can be applied to various fields such as an operation panel of a controller for a construction machine, an aircraft, a light for a television, an input device such as a personal computer or a word processor.

As described above, according to the present invention, the angle detector for detecting the rotation of the gimbal or the like due to the tilting of the operation rod is provided.
A permanent magnet, a magnetoelectric conversion element capable of detecting a change in the magnetic field from the permanent magnet, and a gonio plate made of a magnetic material that rotates together with a gimbal or the like, and a portion of the gonio plate facing the magnetoelectric conversion element. Since the through hole through which the magnetic flux does not pass is formed so as to be continuous in the direction of rotation of the angle changing plate and the position of the portion overlapping the magnetoresistive element changes as the angle changing plate rotates, It produces the effect like. (1) A bending plate can be manufactured by simply molding a plate made of a magnetic material with a press or the like, and the manufacturing cost can be significantly reduced. As a result, a highly accurate joystick with a long life and a compact structure can be provided at low cost. (2) Since it is not necessary to attach a circular arc-shaped yoke as in the past, and because it is not necessary to consider the attachment accuracy, production work becomes easy. (3) The angle sensor can be arranged in the base, and unlike the conventional sliding type variable resistor, the joystick mounting space can be reduced without protruding outside the base. (4) Since it is a non-contact type, its structure is simpler than that of a conventional sliding type variable resistor, and its long life and high accuracy improve reliability.
