Abstract

PURPOSE:To shorten the whole length of a mover without increasing the stress of a plate spring by a method in which a recessed notch is provided in the longitudinal direction of the plate spring, and an operator is fixed to the recession of the notch by one-spot welding. CONSTITUTION:In the mover of a printing head in which an operator 18 is welded to a plate spring 19 for fixation, the whole length of the mover is shortened by the length L6 of the recessed notch 20 of a plate spring 18. The end portion 18a of the operator 18 is lengthened, and the projected portion of the notch 20 of the spring 19 is likewise lengthened. Spot welding is made at least one place (weld 22b) to the projected portion of the spring 19. The distance S2 between the welds can thus be sufficiently increased and the bonding strength between the operator 18 and the spring 19 can be strengthened. No variation in the length L4 of the recession of the spring 19 occurs. The whole length of the mover can be shortened, and the outside diameter of printing head can be reduced without increasing the stress of the plate spring 19.
