INK-SUPPLY DEVICE AND INK-PACK HOUSING CASE

摘要

An ink-supply device comprises: a body in which at least one housing space is formed and which is for housing at least one ink pack in the respective housing spaces; ink discharge tubes which are coupled to ink outlets of the respective ink packs; ink-supply tubes which are coupled to a cartridge; and a coupling members which are coupled between the ink-supply tubes and the ink discharge tubes linked to ink packs of the same color. A multiple loading type of ink-supply device is positioned below the cartridge such that excessive ink pressure does not occur in the cartridge and there is therefore the advantage that damage to the cartridge head can be prevented even without providing a separate damper.
