Abstract

PURPOSE: To obtain a highly-durable, inexpensive printing head through the process consisting of placing plate springs between flap armatures and cores and fitting the base ends of printing needles on the tips of the springs so that the curvature between the base ends and tips of the needles may be reduced.
CONSTITUTION: Plate springs 9 for resetting flap armatures 3 are placed between the armatures 3 and cores 5 and monolithically moulded into comb-teeth form so as to work on all the armatures 3. Printing needles 1 are attached to the tongue- shaped portions 10 at the tips of the springs 9. The blind rotation of the springs 9 is prevented by the arc-shaped projections 19 of spring receiving rings 17. When power is supplied to coils 6, magnetic paths are formed between yokes 4, the cores 5, the armatures 3 and plate pieces 12, and the armatures 3 are attracted by the cores 5 counter to the elasticity of the springs 9 so that the needles 1 are driven to make printing.
