ABSTRACT:
A serial printer is disclosed in which a serial printer body is connected to a carriage via a cable. The carriage is driven by electric power supplied through the cable, and signals are also transmitted between the serial printer body and the carriage through the cable. The cable comprises a sheet-like substrate and a plurality of conductive strips which are formed on the sheet-like substrate and which extend in a longitudinal direction of the sheet-like substrate. The plurality of conductive strips includes at least one wide conductive strip for supplying the electric power and at least one narrow conductive strip for transmitting the signals. The wide and narrow conductive strips are arranged such that noise created by the electric power supplied by the wide conductive strip does not interfere with the signals transmitted in the narrow conductive strip.
