Abstract

PURPOSE:To provide the titled structure of a dot printer printing head capable of improving print quality by integrally forming a plate-shaped attaching part, a shaft-shaped torsional spring part, a plate-shaped supporting part and an elastic member with a securely actuated movable piece which gyrates by a magnet fixed at the attaching part. CONSTITUTION:If a coil 36 is energized, a core 30 is excited and its magnet 32 attracts a movable piece 16. Then the movable piece 16 gyrates against the elasticity of a torsional spring part 14c of an elastic member 16 centering around the torsional spring part 14c and hits a stopper 38. At that them, a wire protrudes way out being led by an intermediate guide 20 and a top guide 22 to carry out printing. After completion of printing, if the coil 36 is deenergized, the movable piece 16 is restored to its original position by the elasticity of the torsional spring 14c.

However, in the conventional support structure shown in Fig. 1, all the leaf springs (3) do not always bend from the same position.
Since it is difficult to make the bending uniform, there are differences in the movement of each movable piece (1), and along with this, the leaf spring (3)
) also changes the attraction position of the electromagnet, and the movable piece (1)
operation becomes uncertain.

For example, dot printers have the disadvantage of poor print quality. Magnetic relays and the like have had the problem of malfunctioning. In addition, in the dot printer shown in the figure, when printing is performed, the wire (3) receives a reaction force in the direction of the arrow in the figure, which causes the leaf spring (3) to wave and cause the movable piece (1) to move. Disturbances may occur, which may affect print quality.

肱−−1 そこで、この発明によれば、以下の効果を生ずる。Elbow--1 Therefore, according to the present invention, the following effects are produced.

(1)可動片は、軸状のねじりばね部を中心として回動

もない電磁石によりいつも一定位置を吸引されることと
なるから、作動もきわめて安定している。しがも1弾性
部材の取付部にしっかりと固着されるから、可動片の前
後左右への動きは確実に規制され、たとえばドツトプリ
ンタの印字ヘッドに使用すると印字品質を良好に保持す

を確実にすることができる。
(1) Since the movable piece rotates around the shaft-shaped torsion spring part, it always operates uniformly, and as a result, it is always attracted to a fixed position by the electromagnet, so it does not operate. Extremely stable. However, since it is firmly fixed to the mounting part of the elastic member, the movement of the movable piece in the front, back, left, and right directions is reliably regulated.For example, when used in the print head of a dot printer, it is possible to maintain good print quality. When used in magnetic relays, etc., operation can be ensured.

(2)可動片は、ねじりばね部の弾性に抗して作動し、
その弾性によって元の位置に復帰する。よって、ねじり
による弾性を利用するから、可動片の応答速度を従来に
比し格段に速くすることができ、たとえばドツトプリン
タの印字ヘッドに使用すると高速印字を可能とし、マグ
ネットリレーなどに使用すると迅速な作動が可能となる
(2) The movable piece operates against the elasticity of the torsion spring part,
Its elasticity allows it to return to its original position. Therefore, since the elasticity caused by torsion is utilized, the response speed of the movable piece can be made much faster than before.For example, when used in the print head of a dot printer, high-speed printing is possible, and when used in magnetic relays, etc., it is possible to quickly print. Operation becomes possible.

(3)部品点数が少なく、構造が簡単で、製作および組
立が容易であり、安価とすることができる。
(3) The number of parts is small, the structure is simple, manufacturing and assembly are easy, and the cost can be reduced.

(4)占有スペースが小さく、全体を小型にすることが
できるとともに、狭い場所への組込みも容易である。
(4) It occupies a small space and can be made compact as a whole, and can be easily installed in a narrow space.
