を行うようになっている。In a release type print head, an armature supported by a leaf spring is attracted to the iron core by a magnetic flux formed through the armature and the iron core by a permanent magnet, and the armature is fitted into the iron core during printing. By energizing the coil, the magnetic flux is canceled and armature attraction is released, and the armature is activated by the energy previously stored in the leaf spring to move away from the iron core, thereby connecting the armature to the armature. Printing is done using wire.

バイパス磁路部材とアマチュアの対向面が上述のように
傾斜しているため、該対向面を通る磁束により両対向部
材間に働く吸引力はアマチュアを鉄心に向は賦勢する分
力を有する。従って、この分だけアマチュア吸引力は増
加し、印字の高速化、長ストローク化が可能になる。(Function) Since the opposing surfaces of the bypass magnetic path member and the armature are inclined as described above, the attractive force acting between the two opposing members due to the magnetic flux passing through the opposing surfaces is a force that urges the armature toward the iron core. Therefore, the amateur suction force increases by this amount, making it possible to print at higher speeds and achieve longer strokes.
以下、第１図及び第２図に関連して本発明の詳細な説明
する。The present invention will now be described in detail with reference to FIGS. 1 and 2.
第１図は本発明に係る釈放型ドツトプリンタの要部を示
