Abstract

PURPOSE:To enable a top guide to be fixed without using adhesives, by making a frame memorize a position at a high temperature by using a shape memory alloy. CONSTITUTION:A printing head which prints with a tip of a print wire 1a via a ribbon by attracting an armature assembly 1 to a coil by making current flow, sets a top guide 2 by using a frame 3 manufactured by a shape memory alloy memorizing a positioning surface 3a and a fixing groove 3b in order to fix the top guide 2 of each print wire Ia. Thereafter, by returning to a memorized state by heat, the top guide can be positioned at a fixed position without adhesives.
