本考案は、交差コイル式計器の指度調整装置に関するも
のである。[Detailed Description of the Invention] The present invention relates to a finger index adjustment device for a crossed coil type instrument.

指度特性が不揃いとなる欠点があった。In general, cross-coil instruments are susceptible to shape errors due to variations in the winding of the cross-coils formed by winding them around the coil bobbin, deformation of the case for forming the magnetic circuit, or errors in the way the case is positioned with respect to the movable permanent magnet. etc., there was a drawback that the individual index characteristics were uneven.
本考案は、上記欠点を解消するためになされたものであ

差コイル式計器の指度調整装置を提供することを目的と
するものである。The present invention has been made in order to eliminate the above-mentioned drawbacks, and an object of the present invention is to provide a finger index adjustment device for a crossed coil type instrument that can easily adjust individual index characteristics to desired characteristics. It is.
以下に本考案を第１図乃至第３図に示す一実施例につい
て説明すれば、１は半径方向に２極着磁された可動永久

下ハウジング３，３′内に回転自在に収納支持されてい
る。An embodiment of the present invention shown in FIGS. 1 to 3 will be described below. Reference numeral 1 denotes a movable permanent magnet magnetized with two poles in the radial direction, which is fixed to a pointer shaft 2, and has upper and lower housings that also serve as coil bobbins. It is rotatably housed and supported within 3 and 3'.
４．４′は互に直交して配置された一対のコイルで、前
記上下ハウジング３，３′に巻回されており、測定信号
に応じた方向の合成磁界を発生せしめる。A pair of coils 4.4' are arranged perpendicularly to each other and are wound around the upper and lower housings 3, 3' to generate a composite magnetic field in a direction corresponding to the measurement signal.
５はソフト磁性材で作られたカップ状の磁気回路形成用
ケースで、前記コイル４，４′の外側に配設されており
、その側壁部には多数の切込みを設けることによって成
形された複数個の空隙調整用舌片６が設けられている。Reference numeral 5 denotes a cup-shaped case for forming a magnetic circuit made of a soft magnetic material, which is disposed outside the coils 4 and 4', and has a plurality of holes formed by providing a large number of notches on its side wall. A number of gap adjusting tongue pieces 6 are provided.
したがって、各舌片６を適宜その板厚方向に曲げること
により、可動永久磁石１との間隔を変えることができる
ので、これによってパーミアンスが変化し指度特性を自
由に調整することができる。Therefore, by appropriately bending each tongue piece 6 in its plate thickness direction, the distance from the movable permanent magnet 1 can be changed, thereby changing the permeance and making it possible to freely adjust the index characteristic.
尚、上記実施例ではケース５と一体的に舌片６を設けた
が、ケースとは別に可変可能な磁気部材を付加しても良
い。In the above embodiment, the tongue piece 6 is provided integrally with the case 5, but a variable magnetic member may be added separately from the case.

成したことを特徴とする交差コイル式計器の指度調整装
置であって、本考案によれば、個々の指度特性を容易に
所望の特性に調整でき、指度特性のバラツキを小さくで
きる。As described above, the present invention includes a movable permanent magnet 1 fixed to the pointer shaft 2, a plurality of coils 4, 4' arranged in a light difference manner so as to surround the movable permanent magnet, and a plurality of coils 4, 4' disposed outside the coils. In the crossed coil type instrument, the case 5 is provided with a plurality of tongue pieces 6 for gap adjustment, and the tongue pieces are bent appropriately to connect the movable permanent magnet 1.
A finger adjustment device for a crossed coil type instrument is characterized in that the finger power is adjusted by changing the distance between the It can be adjusted to the characteristics and the variation in index characteristics can be reduced.
また、調整舌片の変移は可動マグネットの吸引力にも変
化をもたらすので、調整作用が一層顕著に現われる。Moreover, since the displacement of the adjustment tongue also brings about a change in the suction force of the movable magnet, the adjustment effect appears even more prominently.
更に、本考案によれば、ケースが櫛歯状に成形されてい
るので、コイル電流が切れた後には可動マグネットがそ
れまでの指示位置の近くに保持される等の実用的な効果
を発揮するものである。Furthermore, according to the present invention, since the case is formed into a comb-teeth shape, the movable magnet is held close to the previously indicated position after the coil current is cut off, which provides practical effects. It is something.
