发明名称 BACK PRESSURE ADJUSTING DEVICE OF LIQUID JETTING APPARATUS, LIQUID JETTING APPARATUS AND LIQUID STORAGE CONTAINER
摘要 PROBLEM TO BE SOLVED: To provide a back pressure adjusting device of a liquid jetting apparatus which can adjust a differential pressure of liquid by changing the differential pressure between the upstream side of the liquid and the downstream side of the liquid in accordance with a posture at the time of using the liquid jetting apparatus without changing a liquid storage part such as an ink cartridge, and to provide a liquid jetting apparatus and a liquid storage container. SOLUTION: The back pressure adjusting device 700 is equipped with an elastic member 800, and a pressure control member 720 for changing the differential pressure between the upstream side 701 of the liquid of the liquid storage parts 2-5 side and the downstream side 703 of the liquid of a liquid jetting head 30. The elastic member 800 with an opening 801 is disposed between the liquid storage parts 2-5 and the liquid jetting head 30. The pressure control member 720 is inserted in the opening 801 of the elastic member 800 and changes a pressure state of sliding contact to an inner edge part 803 of the elastic member 800 which forms the opening 801, by changing an insertion amount to the opening 801. The liquid is passed between the inner edge part 803 of the opening 801 and an outer peripheral part of the pressure control member 720. COPYRIGHT: (C)2005,JPO&NCIPI
