Abstract

PURPOSE:To form a subject head which is easily assembled and excellent in reliability, by a method wherein an electromagnetic magnet type wire head is mounted at a front stage and a spring release type head at a rear stage. CONSTITUTION:A core 27, in which an armature core 35 is secured at the end thereof and a coil 28 is rolled therearound, is positioned at a permeable plate 26 mounted at a permanent magnet 24, and when electricity is not charged, a plate spring 32, whereat a print wire is attached, is absorbed to the armature 35 to form a head (spring release type) 20 at a rear stage. In the meantime, a core 45, wherearound a coil 46 is rolled, is located at a plate 44 situated at a yoke 25, and when electricity is not charged, a plate spring 40, whereon an armature 42 is secured and a print wire 43 is located, is separated by a gap C from the core 45 to form a head (electromagnetic magnet type) 21 at a front stage. Said two heads 20 and 21 are positioned facing and opposite to each other and joined together by means of a bolt 22 and a nut 23 to form a wire dot head.
