摘要:
An ink-jet head includes a holder having first reference surfaces arrayed at a predetermined pitch in a main scanning direction. A plurality of segment chips is held on the holder. Each of the plurality of segment chips has an ink chamber plate and nozzles, each of the ink chamber plates having a flat surface on which grooves forming ink chambers are arrayed in a row perpendicular to the main scanning direction. Each of the ink chamber plates has a second reference surface extending from and coplanar with the flat surface. The second reference surfaces of the ink chamber plates of the plurality of segment chips are in contact with the first reference surfaces of the holder so that the nozzles of the respective segment chips are positioned on the holder at the pitch in the main scanning direction, and the plurality of segment chips are fixed to the holder.
