Ink cartridge in an ink jet system printer.

摘要

An ink liquid supply system for an ink jet system printer includes an ink intake needle (12) formed in a body of the ink liquid supply system, and an ink cartidge (10) removably mounted on the body of the ink liquid supply system. The ink cartridge includes an opening (64) covered by a seal rubber (66) through wich the ink intake needle is inserted when the ink cartridge is mounted on the body of the ink liquid supply system. An ink liquid absorbing pad (68) is attached to the seal rubber so as to cover the seal rubber. The ink liquid absorbing pad functions to prevent the ink liquid from dropping onto the body of the ink liquid supply system when the ink cartridge is demounted from the body of the ink liquid supply system.
