摘要： An ink channel unit usable in an ink cartridge and a method of manufacturing the same. After preparing a plurality of channel plates formed with ink channels through which ink passes, the plurality of channel plates are arranged and layered, and at least one adhesive sheet having a substantially uniform thickness is disposed between the plurality of channel plates. Then, the plurality of channel plates and the at least one adhesive sheet are pressed and heated at a given temperature to cure the adhesive sheet, thereby adhering the channel plates together. The adhesive sheet includes a base layer and adhesive layers formed on both surfaces of the base layer, and the adhesive layer is made of an epoxy resin. The manufacturing of the ink channel unit is simplified and a time required to manufacture the ink channel unit is shortened, thereby increasing productivity.

摘要： An improved inkjet printer ink cartridge is provided having a print head unit and a housing. The print head unit has a head chip in which a nozzle hole is formed to fire ink onto paper, and a flexible circuit board for transceiving signals with a printer system. The housing has a receiving part at the bottom thereof to receive the print head unit, and an ink chamber disposed therein, the receiving part having an ink feed hole including a dam on its circumference, and a secondary dam of the same height as the dam. Accordingly, when attaching the print head unit into the housing print head receiving part, the print head unit is prevented from being slanted. Further, problems from heat stress when an adhesive is heat cured, such as a membrane crack, or a circuit wire or conductive path breaking, are minimized.
