摘要： A printing head is disclosed in which each attraction member is driven by a magnetic attraction and an impact printing operation is carried out by a strain energy caused by a displacement of a spring member provided on the attraction member. The fulcrum of rotation of the attraction member is defined between the attraction member and a magnetic polar face of a yoke constituting a magnetic circuit together with the attraction member. Means for adjusting the resilient force of the spring member is engaged with a free end of the spring member.
