ABSTRACT:
The present invention relates to a printing wire driving device in a wire dot printer which can perform accurate control with small power and has a large printing wire driving power. In the present invention, a driving member is driven by an eccentric cam. The printing wire can be positively driven with high accuracy by this driving member when a maintaining electromagnet or piezo-actuator holds the wire and driving member in alignment. Otherwise, a biasing member pushes the wire or driving member out of alignment.
