Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on a permanent magnet and a magnetic sensor Vkfl! For the joystick KMI, which is detected without contact, the detection angle C11 is expanded.

In general, K is used for cursor control of CR'r displays, distance control of industrial robots, control panels of TV Goo, etc. K is divided into the direction and size of the #1 diagonal of the control lever, and the electrical utility is joysticks are widely used. This Ji ■ Istic KFi 10,000 Do! There is a contact hole 04 in which the transducer is fixedly arranged in two orthogonal directions and the transducer axis C) (B) is taken out by branching to the rotation angle. String touch m
The withdrawal that is broken down into one rotation angle of the axis becomes narrower, and it is impossible to expect a perfect work.

The blind hole joystick has a ball circle connected to the end of the operating lever O1 & a permanent 6 jewels that is coaxially magnetized.
(9) In the sub-sheath, the magnetoresistive element T is placed perpendicular to the localization 111Kk near the ball C, and the permanent magnet O is applied to each magnetoresistive element by the magnetic field. A non-class type has been proposed in which the operating voltage of each magnetoresistive element is reduced, and the operating lever is divided into the tilt direction and size t, and the voltage is divided into 12 times. Such non-photographing type devices have the advantage of low wear and good operability, but due to the characteristics of magnetoresistive elements, the greater the tilt of the operating lever, the lower the degree of lateral use. However, when the operating lever is actually tilted by an angle τ of ±/J”k, the soft cloth becomes more attached and becomes larger.

The present invention has been made in view of such concerns1,
To provide a non-contact vibration joystick that enables high-precision horizontal use over a wide range. The appropriation of a zero invention will be explained below using an example of a drawing.

The electric stick according to the present invention has a Mizuku magnet meeting on the operating lever! 11, and is provided with a permanent magnet that is integrally formed with the operating lever, and has at least J pairs of mutually orthogonal holes arranged in a magnetic circle 't', and the operating lever This is detected by increasing the magnetic strength of the permanent magnet attached to the main body of the T-hole in the prostrate position. A high-sensitivity Hall element using a conductor with a large Hall coefficient is used, and by arranging two of these in a blood-crossing arrangement, it can be divided into two parts at right angles to the tilt direction of the operating lever and the large viscosity. and misuse it.

The arrangement of the permanent magnet and the two Hall elements is arbitrary, and examples thereof are shown in Figure t-17 and Figure d, and described in e) below.

In the 1@/ figure and the lliJ figure, the Taji operating lever, (

A pair of six Hall elements, each self-sufficient in a 4゛ circle, each filters the ball (2. Interchange and be taken care of.Hall system child 16!

As shown, the 20,000 Doki and the constant O 紦子*m which are perpendicular to the X and Y directions, and the intensity Hti from the X direction (thickness direction) to the A strong magnetic field is applied to the Y-axis @0 Hall element (6) from the -t sensitivity direction (thickness direction), and each Hall element 161i11+

When the operation lever (11) is rotated 1 around the center point Ot-, the permanent magnet fi+ is excited around the center AQ', and the strength of the magnetic field applied to each center point 161 is increased by 1bE operation lever (1!

However, there is no limit to tψ or θ, and this is why Mv is used as the magnetic resistance element 1 in the magnetic sensor mentioned above.
This is a major characteristic of insects.

In each of the examples in the Joki, if the dimensions of the Hall confectionery are the same, there will be a slight difference in the detection sensitivity Jl- by changing the arrangement of the holes, but the dimensions of the Hall element should be made sufficiently relative to the size of the permanent magnet. By making it smaller, the nI+ drive of the upper period sensitivity difference can be solved. Incidentally, the method of making a mallet is not limited to the above-mentioned example. For example, the center of the ball is hollowed out, a hole is placed inside it, and a permanent magnet is placed in the center of the ball.
