Abstract

PURPOSE:To lower the cost through reduction of the number of assembling processes and simplification of assembled structure by combining an actuator member composed of a ringlike plate spring, an armature and a printing wire and a driving member into one unit. CONSTITUTION:The driving member is constituted by the 1st plate 1, a case 2, a permanent magnet 6, a core 7, an exciting coil 8 and the 2nd plate 4, while an actuator member is constituted by a plate spring 9, an armature 10 and the printing wire 11. Then, a ring-form spacer 5 is placed on the upper surface of the case 2 and the actuator member is fitted on to the 2nd plate 4 by inserting the armature 10 into a square-shaped hole 4a made in the plate 4, while the ringlike peripheral edge part 9b of the plate spring 9 is placed on the spacer 5 and a guide frame 3 -- on the ringlike peripheral edge part 9b, and the printing wire 11 is projected upward vertically from a wire guard 12 provided in the center of the guide frame 3.
