<p>In a print head according to the invention, the electromagnets (58) which control the movement of needles (46) and which are disposed around their ends opposite those intended for printing comprise solenoid plungers (76) which are coupled at these ends of the needles by levers (82) made of non-magnetic material, preferably a synthetic material, which are fixed to them. On the other hand, in a preferred embodiment the levers are normally held in a rest position by elastic metal strips (90) which are fixed to their faces opposite the electromagnets and the needles carry overmoulded heads (80) which are simply held bearing against the strips by spiral springs (92) placed between these heads and the first guide device (40) into which the needles pass. <IMAGE></p> |
