<p>An ink jet recording apparatus comprises: at least one recording head (7, 8) having a face on which a plurality of nozzle orifices are formed, the recording head (7, 8) mounted on a carriage (1) to be moved reciprocatively in the widthwise direction of a recording sheet; a capping device (12) disposed in a non-print region of the recording head, the capping device (12) including at least one cap unit (16, 17) for sealing the nozzle-formed surface of the recording head in cooperation with the movement of carriage (1); and a plurality of suction pumps (30) for applying negative pressure in the interior space of the cap unit (16, 17) via suction tubes while the cap unit (16, 17) seals the nozzle-formed surface in cooperation with at least one drive source. The number of the suction pumps (30) is at least equal to the number of the cap units (16, 17). <IMAGE></p> |
