Abstract

PURPOSE:To obtain an ink chamber structure in which the ink liquid path from the tip (narrowest portion) of a conical ion chamber to a nozzle is parallel, and the length (1)-diameter (m) ratio of the parallel liquid pathway is so designated within a specific range that the escape of bubbles in the ink changer is made easier and also the time taken for ink to be finely divided and stabilized is shortened. CONSTITUTION:The length of a parallel liquid pathway 8 is increased so that the ratio of the length (lmm.) to diameter (dmm.), or l/d ratio, is >=2, and also the diameter of a head body 1 is matched with that of a nozzle cap 6 so as to avoid the formation of a step difference at the connected portion A. Thus, the trapping of bubbles can be avoided, and even when bubbles are trapped, they do not go up in the conical ink chamber 2.
