Patent ID: 8651637

Claim:
A liquid supply device comprising: a liquid container comprising: a liquid chamber configured to store liquid therein; a liquid supply portion configured to supply the liquid from an interior of the liquid chamber to an exterior of the liquid chamber; and at least one contact portion; and a mounting portion having an opening, a first surface, and a second surface opposite the first surface, wherein the liquid container is configured to be inserted into the mounting portion in an insertion direction via the opening and to be removed from the mounting portion in a removal direction opposite the insertion direction via the opening, the mounting portion comprising: a joint portion configured to be joined to the liquid supply portion of the liquid container in a mounted state in which the liquid container is mounted in the mounting portion; an urging member configured to urge the liquid container positioned in the mounting portion toward the opening; at least one stopper comprising a resilient member extending from at least one of the first surface and the second surface in a direction intersecting the insertion direction, wherein the resilient member is bendably deformable in both the insertion direction and the removal direction, and wherein the resilient member is configured to contact the at least one contact portion when the liquid container is inserted into and removed from the mounting portion; and a retaining member configured to selectively retain the liquid container in the mounting portion against an urging force of the urging member, wherein when the liquid container is mounted in the mounting portion, the at least one contact portion faces the at least one of the first surface and the second surface from which the resilient member of the at least one stopper extends, and the resilient member is configured such that a first force required for deforming the resilient member in the insertion direction is less than a second force required for deforming the resilient member in the removal direction.
