Abstract

PURPOSE:To obtain a very small size and low voltage and low power driving dot printer which uses an efficient electromagnet with a small gap between a plunger and a fixed core by magnifying the stroke of a plunger-type electromagnet with a printing lever. CONSTITUTION:The shape of a carriage 22 is so determined that a wire 18 may be engaged with a part 19b between the dot striking surface 19a of a printing lever 19 and a shaft 20. The printing lever 19 energized by a return spring 21 in the direction of an arrow mark B is rotated in the opposite direction of the arrow mark B via a plunger 14 attached to the wire 18 when a coil 11 is excited and one-round magnetic path by a fixed core 13, the plunger 14, a yoke 16 and a yoke 15 is formed.
