Ink cartridge and ink-jet recording apparatus using the ink cartridge

摘要

An ink cartridge being vertically mounted comprises a housing that is provided with an ink discharge port, an ink pack that is disposed within the housing, and a pressing mechanism that presses the ink pack. The pressing mechanism includes a contact and a biasing member. The contact is movably disposed within the housing and in contact with at least a part of the ink pack lower than the ink discharge port. The biasing member biases the contact toward the ink pack in a direction at an angle to a vertical direction.
