徴とするばね釈放型ドツトプリンタのワイヤ駆動装置。a yoke having a permanent magnet inserted in the middle of the leg and having both end faces facing each other with a predetermined gap; a coil wound around the leg to offset the magnetic attraction force of the permanent magnet; It consists of a leaf spring fixed to a yoke and an amatia whose one end is fixed to the free end of said leaf spring and whose other end drives a wire and whose part is located in said gap, said coil is not energized. When the amatia is attracted to one end surface of the yoke and applies a biasing force to the leaf spring,
In the wire driving device of the spring release type dot printer, the biasing force of the leaf spring is released and the amatia is displaced until it comes into contact with the other end surface of the yoke to drive the wire when the coil is excited. A spring release type characterized in that the other end surface and the opposing surface of the amatia facing the other end surface both form circular arc surfaces with the same radius, and are positioned so that the spacing in the displacement direction of the amatia is equal. Wire drive device for dot printers.
