Abstract

PURPOSE:To suppress high order vibration small and to prevent not only the generation of the rebounding of a wire but also the lowering in printing quality, by forming a tongue part stretched from the leading end thereof to the rear end thereof to the central part of a leaf spring and pressing a frame by the tongue part with the restoration of the leaf spring to brake an armature. CONSTITUTION:In such a state that no current is supplied to a coil 2, a leaf spring 11 deforms to be brought into contact with a base yoke 1 and, when a current 2 is supplied to the coil 2 from this state, the flux of a magnet 3 is off-set and the leaf spring 11 is separated from the base yoke 1 by the elastic force of the leaf spring 11 and a wire 7 moves toward a printing medium to be brought into contact therewith to perform printing. When the wire 7 is brought into contact with the printing medium, an armature 6 is ready to revolve centering around the vicinity of the leading end thereof but a tongue part 11a is brought into contact with a side yoke 9 and the armature 6 revolves around the end part of the tongue part 11a and, therefore, high order vibration is suppressed low.
