Abstract

PURPOSE:To obtain the captioned head which is easy for assembly and adjustment and is small in the number of parts by a method wherein specified wire units and magnet units are piled and combined. CONSTITUTION:Ends of print wires 3 are fixed to each spring piece 4a of a disk spring 4 to make up a wire unit. On one hand, a permanent magnet 10 is charged in a york 11 and calked by cores 9 and, furthermore, magnet coils 8 are placed on the cores 9 to form a magnet unit. These two units are heaped up through a spacer 6, while the front portion of the print wire 3 is penetrated through guide holes 1a and a guide frame 2 is placed on the wire unit or the disk spring 4 and is combined with each other by screws 12.
