INSERTION/EXTRACTION MECHANISM FOR AN INK CARTRIDGE

摘要

An ink cartridge insertion/extraction mechanism includes a cover pivotally mounted to the housing of the ink cartridge holder. A pair of links are pivotally mounted to the cover and extend into the ink cartridge holder. The bottom of each link is provided with a boss that extends into the ink cartridge holder that contacts the bottom of ink cartridge. As the cover is rotated closed, a pushing rib on the cover contacts the top of the ink cartridge and pushes the ink cartridge further into the holder, causing the needles to puncture the septum of the ink cartridge. To extract the ink cartridge, the cover is rotated from the closed position to the open position, lifting the links until the bosses at the bottom end contact the bottom of the ink cartridge and lift the ink cartridge off of the needles.
