<P>PROBLEM TO BE SOLVED: To provide a printer device capable of eliminating electromagnetic trouble in transferring clock pulses. <P>SOLUTION: In a printer 1, at least a data transfer line and two clock pulse transfer lines 5a are disposed on a flat cable 5 which connects a recording head 4 and a recording head control unit 3, the clock pulses in a normal phase and a reverse phase are transferred to these clock pulse transfer lines 5b, 5b and these clock pulse transfer lines are disposed so as to surround a return ground line 5c for clock of the flat cable. When an electric current is carried in each clock pulse transfer line at the clock pulse transfer, the electromagnetic field (electric wave) is generated by this configuration, and the phase difference becomes 180° and carried electric current is carried in the reverse direction to a common return ground line for clock and therefore, the electric current is canceled and the generation of an electromagnetic field and radiation noise can be suppressed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
