Dot printer head with alternate magnetic flux paths

摘要

The printhead is constructed such that opposed surfaces of armatures are formed between the armatures adjacent to each other with small gap being left therebetween and cores opposed to each of the armatures are provided with alternative opposed magnetic fluxes. The armatures are supported in such a way that the guide holes formed in the middle of each armature are engaged with the fixed armature guides without interfering with their side surfaces, and thereby side magnetic paths of sufficient cross sectional area can be formed, and further their equivalent mass can be decreased and a high speed printing is enabled, and the armatures can be moved smoothly.
