PROBLEM TO BE SOLVED: To provide a print head in which repair cost is reduced and the effective use of a component is enhanced by replacing the component in minimum unit upon the occurrence of a trouble such as the breakage of a print wire. SOLUTION: In the print head having a leaf spring 7 where a plurality of flexible portions 7b are connected at an outer circumferential part 7a, the outer circumferential part 7a is composed of the proximal portion 7c of the flexible portion 7b and a fixed portion 7e for bonding the leaf spring 7. A cut 34 is formed between the proximal portion 7c and the fixed portion 7e so that they can be cut off, and grooves 36a and 36b are formed at both ends of the cut 34. Furthermore, a cut 35 for positioning a replacing flexible portion assembly is formed continuously to the cut 34. The replacing flexible portion assembly is provided with a protrusion corresponding to the cut 35 for attachment. COPYRIGHT: (C)2007,JPO&INPIT
