INK JET HEAD UNIT AND INK JET RECORDING APPARATUS MOUNTED WITH THE SAME

摘要

An ink jet head unit comprises a head (2) in which plural nozzle arrays (2a, 2b, 2c, 3d) of which each comprises many nozzle holes are formed, and ink is ejected from the nozzle holes; a head base on which the head (2) is mounted; and flat cables (4a, 4b) flexibly formed by covering many transmission wires with an insulation film, of which one end sides where the transmission wires are exposed are fixed, in mounting parts (7a, 7b) interposed between the nozzle arrays (2a, 2b) and the nozzle arrays (2c, 2d,) onto the head thereby to transmit ink ejection signals for driving the head.
