Abstract

PURPOSE:To prevent occurrence of deviation in printing pressures due to an upper stage and a lower stage one by a method printing wires of the upper stage head and of the lower stage head are arranged so that they operate alternately. CONSTITUTION:A coil 14 provided on a core 13 of a magnetic base 12 and an armature 18 fixed to a magnetic member 15 forming a magnetic circuit with the above-said parts and a spring 17, etc. make an upper stage head 11A. In a printer head composed of the upper stage head 11A and a lower stage head 11B equivalent to it, a printer wire 22a of the upper stage head 11A and a printer wire 22b of the lower stage head 11B are arranged so that they are operate alternately in a paper feed direction Y.
