Abstract

PURPOSE:To obtain an impact-type dot printing head having small power consumptiveness, small thermogenous property, and a great impacting force by providing a specific aperture between a printing magnet and an armature and also providing a permanent magnet specifically. CONSTITUTION:The rear portion 5a of a printing wire 5 is touched by an armature 4 and the supporting point of the armature 4 is pushed by a spring 6 to prevent its floating. The printing wire 5 is restored to a quiescent state by a reset spring 7, and the armature 4 is held at a position facing the end face of the core by means of the armature holder 9. A permanent magnet 10 is provided in the attracting direction of the armature 4, and its polar face is positioned so as to face an attracting space 11 between the printing magnet 1 and the armature 4. Also, an aperture 12 is provided between the permanent magnet 10 and the armature 4 stopping at a stopping position.
