摘要： An ink cartridge using separate magnets is provided. The ink cartridge includes an ink container, which includes first and second chambers separated by a vertical partition formed therewithin for containing ink, and a head for ejecting the ink in the ink container onto a printing medium in the form of droplets. The first chamber includes a sponge filling most of the inside of the first chamber, a filter provided on a bottom portion of the sponge, and an ink supply pipe for supplying the ink which has passed through the filter to the head. The second chamber includes a magnet float floating on the ink in the second chamber and including a first magnet in its inside, and a second magnet provided in the bottom surface of the second chamber. The ink cartridge includes a magnet sensor for detecting a magnetic flux having at least a predetermined level when the magnet float contacts the second magnet. Accordingly, the ink cartridge with separate magnets does not require a cartridge container to be formed of a transparent material. By using the separate magnets, a magnetic flux having a strength necessary for detection can be induced while preventing magnetic interference between ink containers provided for different colors.

摘要： An ink cartridge including an ink storage chamber in which ink is stored, a cover to cover the upper portion of the ink storage chamber and a head to eject ink droplets in the ink storage chamber onto a recording medium, wherein the cover includes an inner cover to cover the upper portion of the ink storage chamber and an outer cover that seals the ink storage chamber and the inner cover, and is positioned at a predetermined distance above the inner cover. Also provided are plates to form zigzag air passages by blocking a space between the inner cover and the outer cover. With the ink cartridge according to the present invention, it is possible to satisfactorily suppress the backward flow of ink contained in an ink storage chamber due to overheating of or careless treatment of the ink cartridge. Even if ink flows backward from the ink storage chamber, it is stored in an ink storage space, thus preventing the clogging of an air passage. Further, air entering the ink storage space is filtered, passing through the air passage, and additional components are not required to seal up an opening to which ink is supplied. For this reason, manufacturing costs can be reduced and a manufacturing process can be simplified.

摘要： A bonding structure to align and bond a plurality of print heads on an ink channel unit of an ink cartridge includes a preliminary bonding tab, a main adhesive, a plurality of print heads, and a preliminary adhesive. At least one preliminary bonding tab is formed at a perimeter of each of a plurality of print head bonding areas on a surface of an ink channel unit. A main adhesive is applied to each of the plurality of print head bonding areas. The plurality of print heads are arranged respectively over the main adhesive. A preliminary adhesive is applied to spaces between each of the plurality of print heads and at least one preliminary bonding tab corresponding thereto. When a plurality of print heads are preliminarily bonded by the preliminary adhesive, the plurality of print heads are bonded to the surface of the ink channel unit by heating and hardening a main adhesive.
