PRESSURE ADJUSTMENT MECHANISM, LIQUID TANK, LIQUID PROVIDING DEVICE, INK CARTRIDGE, AND INKJET PRINTING APPARATUS |
摘要 |
A pressure adjustment mechanism can provide ink to a subtank with the inside of the subtank being opened to outside air, by using a low driving force. A liquid tank holds liquid to be used by a printing apparatus. The liquid tank has a structure in which a capacity of the liquid tank can be changed so as to generate a negative pressure in the liquid tank. The liquid tank includes a case having an opening at one side of the tank, and a flexible film that covers the opening, and a compressed spring in the tank for pressing the film outwards.
