Abstract
An impact wire-dot printing head comprising a frame (4, 15, 32); impact dot printing mechanisms, each comprising an armature (1) having an outer end pivotably supported by the frame means, an electric magnet for attracting the armature (1) an impact dot-wire (3) being driven in an axial direction thereof by the armature (1). The armatures (1) are radially arranged on an arrangement face perpendicular to the direction in which the dot-wires are driven, and the outer end of each armature (1) is provided with a projection (5) protruded perpendicularly to the arrangement face and in a direction opposite to the direction in which the dot-wire (3) is driven. The frame is provided with slots (6) for loosely accommodating the projections (5) of the respective armature (1), so that a movement of the armature (1) in the arrangement face is restricted.
