Liquid injecting apparatus

摘要

In a liquid injecting apparatus in which ink is supplied from an ink tank to a print cartridge detachably mounted on a carriage through a tube, connection between an ink needle at a tube side and an interconnecting member at a cartridge side can sealingly be effected positively, and ink supplying and connecting means can be made compact. A closing film having a small hole and a central slit is provided at a tip end of an interconnecting member made of soft material and fitted into an ink flow-in projection portion of the print cartridge into which an ink needle is inserted. Further, a notched needle tip end avoiding configuration is provided at a lower part of a tip end of the projection portion so that abutment between the projection portion and the ink needle can be avoided when the print cartridge is mounted and dismounted, thereby reducing a shifting amount of a needle holding member.
