Abstract

A spring charge type wire dot printing head includes front cores 35 and rear cores 36 that are disposed in circles. The front and rear cores are used in pairs, and either one of these paired cores is wound with a coil 39 or 40. Since the inductance of the coils 39 and 40 can be increased, low electric current and low electric power consumption can be realized.
