DEAERATION SYSTEM AND INK-JET RECORDER

PROBLEM TO BE SOLVED: To provide a deaeration system in which a deaeration module deaerates liquid by using a place adjacent to a place where a hollow fiber membrane is disposed, and to provide an ink-jet recorder with the deaeration system.SOLUTION: The deaeration system includes the deaeration module 10A which is provided with a deaeration film 11 having gas permeability, and fills one side of the deaeration film 11 with liquid 3, decompresses the other side of the deaeration film 11 to deaerate the liquid 3. The deaeration membrane 11 comprises a plurality of hollow fiber membranes, the deaeration module includes a hollow fiber membrane bundle 11a where a plurality of hollow fiber membranes are adjacently placed and gathered in a bundle shape at one side of the deaeration film and liquid accumulation parts 17, 18 which are adjacently placed outside the hollow fiber membrane bundle 11a and accumulate liquid. A transition means performs intermittent transition which repeats stop and transition intermittently.
