PURPOSE:To reduce a labor of replacing a printing head by providing a board associated with a printing unit and a holder, a leads for connecting terminal of a piezoelectric element, and a flexible printed board connected with an end terminal connected to printing control means. CONSTITUTION:A nose 51 is formed in a protruding state at the center on the front face of a board 50, a printing unit PU is inserted into the slit 42 of a holder 40, a tiltable arm 10 is guided by a guide 43 to telescopically guide a printing wire 11. A flexible circuit board 70 is partly wound on the outer surface of the main body 41 of the holder 40 of an associated printing head PH, and the leads 14P, 14N of a piezoelectric element 1 are connected to a lead connection terminal 17 through a guide groove 2a formed on a main frame 2 in a state that a winding part 70a is wound on the body 41 in such a manner that the cutout 70b corresponds to the groove 2a. Accordingly, when the printing unit is replaced, it can be replaced merely by removing the leads of only one element, and a labor of replacing can be reduced in this manner. |
