PRINTING HEAD

摘要

PURPOSE:To enhance durability and printing capacity, by arranging a plurality of thin wire guide plates having guide orifices at a position along the curved parts of printing wires between the return spring attaching part of a head main body and the bearing provided to the leading end of said main body. CONSTITUTION:A plurality of printing wires 2 held in a freely slidable manner in such a state that a matrix is arranged to the leading end part of a head main body 1 by the bearing 3 arranged to the leading end of said main body 1 are always energized to the rear direction of the head main body 1 by return springs 4 provided to the rear part of said main body 1. The electromagnetic solenoid 5 attached to the flange part 1a of the head main body 1 is provided so as to respectively correspond to the printing wires 5 and made movable by the electromagnetic solenoid 5. Thin wire guide plates 9 have guide orifices at positions along the curved parts of the printing wires 2 so as to minimize the curving of the printing wires 2.
