ABSTRACT:
A piston is slidably arranged in an ink chamber designed to communicate with a recording head through an ink passage. The pressure inside the ink chamber is kept to a predetermined negative pressure at all times by taking advantage of the tare of the piston. As a result of this construction, leakage of the ink from a recording head can be prevented independently of the ink tank mounting position or temperature fluctuations.
