Ink-jet printing apparatus and ink cartridge

摘要

The cartridge (2) has an ink supply port (6) to supply ink from an ink chamber (4) to a print head (102) of a printing apparatus. A packing unit (8) seals an ink supply needle (104) of the printing apparatus. A valve device (10) contained in the ink supply port elastically abuts against the packing unit. The valve device selectively opens and closes the ink channel in conjunction with the ink supply needle. An independent claim is also included for a printing apparatus for ejecting ink on a printing medium.
