Patent ID: 7753498

Claim:
An image recording apparatus comprising: an inkjet printhead having: a plurality of pressure chambers; a common ink chamber that is commonly connected to the pressure chambers to supply ink therefrom to the pressure chambers; a nozzle surface including: a nozzle area in which a row of nozzles respectively connected to the pressure chambers are open, the ink supplied to the pressure chambers being then supplied to the corresponding nozzles to be ejected therefrom; and an overlapping area that overlaps with the common ink chamber in a direction perpendicular to the nozzle surface; a cap which has a close-contact portion, and is configured to shift into contact with, and away from, the nozzle surface, and when in contact with the nozzle surface, the cap air-tightly closing the nozzle surface with the close-contact portion encircling the nozzle area and not contacting the overlapping area; wherein the inkjet printhead is constituted by a laminate of a plurality of plates including a first plate through which the nozzles are formed, and a second plate through which an opening constituting the common ink chamber is formed, the first plate being disposed to be opposed to the cap, and the second plate being disposed directly on a side of the first plate remote from the cap; and wherein the common ink chamber extends along the nozzle row and at a position away from the nozzle row in a direction perpendicular to an extending direction of the nozzle row in a surface of the second plate.
