A carrier frame is provided for oscillation along a printing platen of the printer and is comprised of two integral, U-shaped sections facing each other at right angles. A plurality of electromagnetic actuators are arranged in one section and include a yoke, a coil, and a pivot armature in each instance. A free end of the pivot armature projects into the other small section. A relatively short print needle is guided in one wall portion of the second section and has its rear end abutment with the projecting end of the armature; an adjusting screw adjusts the relative disposition of the pin-like needle and the armature; the common pivot axis for all armatures is established by a resilient string in a cover plate across the larger U. |
