The nozzle block includes a plurality of nozzles in which the ink is emitted. A plurality of inner pipes are combined on the nozzle block attachably. A plunger adjusts dot size of the nozzle. The first supporting fixing unit has a plurality of through-holes(50a). The second fixing supporting unit is combined on a front panel faced with the nozzle block.
