摘要： In order to realize a stabilized pivotal movement of an armature to thereby obtain pivotal force required for high-speed printing, a pivot shaft is held such that an armature having an attracted face that is in contact with a core, that has a coil wound therearound and has a pole face, and the pivot shaft is opposed to the core, whereby the armature becomes pivotable. An attracting direction of attraction force F acted on the attracted face by the core and the moving direction in which the attracted face moves due to the attraction force F are made substantially equal to each other.

摘要： A wire dot printer head of the present invention has an armature that has an arm supporting a printing wire and pivotably provided at the position opposite to the core, and a coil spring that one end comes in contact with the arm for urging the armature in the direction away from the core, wherein the one end of the coil spring supported by the supporting member is brought into contact with the armature to apply return force to the armature. In order to prevent the breakdown of the armature due to a contact of the coil spring and to realize a stabilized urging operation of the coil spring, a winding end of the coil spring at the one end is located at the position inside of the coil spring and nearer to the supporting member from the contact position where the coil spring comes in contact with the armature.
