。Technical blue potentiometer transmits external mechanical displacement to the drive shaft,
By rotating or linearly displacing the shaft, it moves over the contacts of the slider attached to the shaft or on the resistance element, and changes in resistance due to changes in the contact to this resistance element cause mechanical damage. This detects the amount of electrical displacement corresponding to the amount of displacement.
従って、この様なポテンショメータ又は、摺動子の接点

０．５１は端子である。Prior art t417 and its problems Therefore, conventionally, a potentiometer as shown in FIG. 4 has been used. This is because the slider 42 which has an elastic force on the drive shaft 41. /13 installed, slider 42.43
The contact point is attached to the inner surface of the casing 4/l (it moves over the resistor cable 45 and the conductor element/16). Reference number 47 is a bearing, 48 is a spring, 49, 5
0.51 is a terminal.

による抵抗値の変化により電圧を検出するものである。1, that is, the drive shaft 41 is linearly displaced by an external mechanical displacement, and the slider 42.4 is attached to the drive shaft 41.
3 slides on the resistor element 45 and the conductor element 4G, and voltage is detected by a change in resistance value due to a change in the contact point to the resistor element 45 corresponding to the amount of mechanical displacement.
摺動子４２．４３は弾性力を有するので、駆動軸４１が
傾いても確実に抵抗素子４５と導体素子４６に接しなが
ら接点が変化することができる。Since the sliders 42 and 43 have elastic force, even if the drive shaft 41 is tilted, the contact points can be changed while reliably contacting the resistive element 45 and the conductive element 46.
しかし、この場合は、摩擦抵抗が大きく、誤差が大きく
なる問題がある。これは、摺動子４２゜４３の接点が抵
抗索子４５及び導体素子４６上を摺動するためである。However, in this case, there is a problem that the frictional resistance is large and the error becomes large. This is because the contacts of the sliders 42 and 43 slide on the resistance cord 45 and the conductive element 46.
接点の接触力を小さくずれば摩擦抵抗は小さくなるが、
接点の信頼性に欠ける。If the contact force of the contact point is shifted small, the frictional resistance will be reduced, but
Contacts are unreliable.
技術的課題
本発明の技術的課題は、接点の接触力を維持して、摩擦
抵抗を小さくすることである。Technical Problem A technical problem of the present invention is to maintain the contact force of the contacts and reduce the frictional resistance.
技術的手段
上記の技術的課題を解決するために講じた本発明の技術
的手段は、駆動軸に磁石を取り付け、磁性体でかつ導体

と導体素子を取りイ」げた、ものである。Technical Means The technical means of the present invention taken to solve the above-mentioned technical problem is to attach a magnet to the drive shaft, arrange a spherical member made of a magnetic and conductive material away from the magnet, and to increase the movement range of the magnet. It consists of two resistive elements, or a resistive element and a conductive element, which are in contact with a magnetic material over the entire length.
ここで、磁石は、球状部材が抵抗素子、導体素子に確実
に接するだけの強さのものを用いる。Here, the magnet used is one strong enough to ensure that the spherical member contacts the resistive element and the conductive element.
技術的手段の作用 上記の技術的手段の作用は下記の通りである。Action of technical means The operation of the above technical means is as follows.
球状部材は磁性体であり磁石に吸引される。この吸引力
により球状部材は抵抗素子、導体素子に確実に接触し、
磁石の変位とともに抵抗素子、導体素子上を転がる。す
なわち、導体である球状部材が接点になり、球状部材が
転がることにより接点が変化するので、摩擦抵抗が小さ
くなる。The spherical member is a magnetic material and is attracted to the magnet. This attractive force causes the spherical member to reliably contact the resistive element and conductive element.
As the magnet is displaced, it rolls on the resistive element and conductive element. That is, the spherical member, which is a conductor, becomes a contact point, and the contact point changes as the spherical member rolls, thereby reducing frictional resistance.
特有の効果 本発明は下記の特有の効果を生じる。Unique effects The present invention produces the following unique effects.
球状部材の球面全体を接点にできるので、接点の寿命か
長くなる。Since the entire spherical surface of the spherical member can be used as a contact point, the life of the contact point is extended.
駆動軸と接点となる球状部材どは機械的に非接触であり
、駆動軸の摩擦抵抗が増加せず誤差が少ない。The spherical members that come into contact with the drive shaft are mechanically non-contact, so the frictional resistance of the drive shaft does not increase and errors are small.
摩擦抵抗が小さいので、接点の追従性が良くなり、ヒス
テリシスが小さく、分解能が向上する。Since the frictional resistance is small, the followability of the contact point is improved, hysteresis is small, and resolution is improved.
