Abstract:
To prevent the lowering of a printing grade caused by air bubbles accumulated in the vicinity of the jet orifices of a recording head.
Ink supply ports 101A, 101B different in cross-sectional area are provided with respect to the row of the jet orifices 24a of a liquid jet recording head as air bubble stagnation means so that air bubbles are stagnated in a common liquid chamber 103 with which the jet orifices communicate at a predetermined position 103A.
