That is, the present invention includes a flat plate-shaped base, a plurality of rod-shaped cores mounted on the base, and a coil attached to the lower side of the periphery of each core so as to generate an electromagnetic force by an electric signal. , furthermore, an annular permanent magnet fixedly attached on the coil and around the core; a spring made of a thin plate spring disposed at right angles to the core with a slight gap at the tip of the core; A plate of magnetic material is attached and fixed to the spring so as to be attracted by a permanent magnet, a printing wire is attached and fixed to the tip of the spring, and the suffling and the base are fixed and protected, and the heat generated from the coil is removed. It is equipped with a case that releases radiation to the outside.

次に本発明の実施例について図面を参照して説明する。Next, embodiments of the present invention will be described with reference to the drawings.

In the figure, a plurality of rod-shaped cores 3 are arranged at right angles to a flat plate-shaped base 1, a coil 2 is attached around each core, and an annular permanent magnet 10 is attached to the front surface of this coil. A spring 4 made of a thin plate spring attached to the case 8 via a spacer 5 is arranged at the tip of the core at right angles to the core 3, a plate made of a magnetic material is attached to the spring, and a printing wire 4b is attached to the tip of the spring. It is fixed and movable within the hole of the guide 7.

Next, when a voltage is applied to the coil 2 fixedly attached around the core 3, the annular permanent magnet 10 is energized by the excitation of the coil 2.
Electromagnetic forces of opposite polarity are generated, and the spring assembly 4 is separated by the spring force.

この開離時のスプリングアッセンブリ4の運動によって
印字ワイヤ4bは前方に移動して印字動作する。
The movement of the spring assembly 4 at this time of separation causes the printing wire 4b to move forward and perform a printing operation.
