Abstract

PURPOSE:To obtain a printing head for which a driving efficiency is high, and a high speed driving and a miniature thin type shaping are feasible, by providing permanent magnets arranged in a circumferential type held by a holder, printing levers arranged in a radiant type and a movable coil positioned at a space among permanent magnets. CONSTITUTION:When a pulse type current is applied to a movable coil 4, by means of this current and a magnetic flux passing through a space in cooperation with this current, a displacement force operates to the movable coil 4, as a result, a spring part 3b of a printing lever 3 is deformed elastically against its own spring force, and an inner end part 3d, that is a wire 5 of the printing lever advances to the left side to form a dot. Next thereto, the wire 5 and the printing lever 3 return to the rest position by means of the spring force of the spring part 3b. At this returning, the inner end part 3d of the printing lever 3 collides with an impact absorption member 6 and the returning energy is moderated and absorbed, thus, the collision sound is made small and its rebound is swiftly attenuated.
