<P>PROBLEM TO BE SOLVED: To prevent clogging due to a precipitable composition contained in ink. <P>SOLUTION: An ink holding chamber having a remarkably smaller capacity than that of an ink chamber is provided, while the ink to be introduced into the ink holding chamber is divided by a valve structure using a churning ball. By this constitution, clogging of an ink introduction path from the ink holding chamber to a penpoint member due to the precipitable composition, as well as an excessive supply of the ink due to the air in the ink chamber, can be prevented. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
