Impact dot printer head and printing apparatus

摘要

An impact dot printer head having one or plural heat conductive members. The heat conductive member, with a part in the proximity of armature stopper of the impact dot printer head while another part guided to the outside a housing of the impact dot printer head, conducts heat inside the housing to the outside. Accordingly, as the heat conductive member first conducts heat of the armature stopper to a heat radiation unit outside the housing, degradation of hardness of the armature stopper due to heat can be prevented, and a return position of the armature can be determined in a stable manner.
