Liquid supply system, fluid communicating structure, ink supply system, and inkjet recording head utilizing the fluid communicating structure |
摘要 |
A liquid (ink) supply system having a closed structure with respect to an inkjet recording head is configured such that a gas hindering a recording operation and a liquid supply operation can be rapidly and smoothly eliminated from a liquid supply system without involving any complication in structure. An ink tank (10) and a liquid chamber (50) for leading ink supplied to the recording head (20) are brought into fluid communication via two communication channels (53 and 54). Thus, in the state where the gas exists inside the liquid chamber, the ink is moved from the ink tank (10) via one communication channel (53), while the gas is transferred to the ink tank (10) via the other communication channel (54).
