Patent ID: 7347541

Claim:
A liquid tank comprising: a liquid outlet configured to supply a liquid to a liquid discharge recording head; an air inlet; an absorption chamber containing an absorber absorbing and holding the liquid; a liquid chamber directly holding the liquid supplied to the absorption chamber; and the liquid outlet including a pressure contact body having a stronger holding power than the absorber on liquid in contact with the absorber, wherein the absorption chamber and the liquid chamber are separated by a partition having a communication part allowing communication between the absorption chamber and the liquid chamber and the liquid is supplied from the liquid chamber to the absorption chamber through the communication part and then through an upper edge of the communication part on a side of the absorption chamber, wherein a path configured in a concave/convex form is provided to the side having the liquid outlet, the path is provided throughout the area from inside the liquid chamber to the absorption chamber, wherein the position of the end of the path on a side of the absorption chamber has an area where the absorber exists so that the path and the pressure contact body do not directly communicate between an end on a side of the pressure contact body and an edge of the upper surface of the contact body on a side of the path, and wherein the path includes a member having a liquid flow resistance that is smaller than a liquid flow resistance of the absorber.
