LIQUID DISCHARGING APPARATUS AND HEAD CARTRIDGE

摘要

PROBLEM TO BE SOLVED: To transmit a driving force of a driving part to an operation part of a pressure generating part by making the pressure generating part of a liquid circulating means and its driving part separate members, and combining a head cartridge into an apparatus body part. SOLUTION: The head cartridge 3 equipped with a liquid delivery pump 10 which is disposed on an ink reflux line for returning ink from an ink discharging head 7 to an ink tank 6 and includes the pressure generating part for sucking and discharging to circulate the ink between the ink discharging head 7 and the ink tank 6 is combined into a predetermined part of a printer body part 2 equipped with both the driving part 32 for generating the driving force to operate the pressure generating part of the liquid delivery pump 10 of the head cartridge 3 and a control part 33 for controlling the operation of the driving part 32. Thus the driving force of the driving part 32 can be transmitted to the operation part 28 of the pressure generating part of the liquid delivery pump 10. COPYRIGHT: (C)2005,JPO&NCIPI
