IPC: B41J2/175
Filed: 2002-12-09
Abstract: <P>PROBLEM TO BE SOLVED: To provide an inkjet printer which prevents the occurrence of a printing defect even if air bubbles get into an ink supply tube.  <P>SOLUTION: An air trap 13 is provided in the ink supply tube 12 near an ink supply port 11c of an ink tank 11. The air trap 13 is formed as a rectangular parallelepiped-shaped space wherein a passage length is represented by Lx, wherein a height of an outflow port 13a to a downstream side, measured from an ink-flow bottom part, is represented by Ly, wherein a height up to an uppermost part, measured from the ink-flow bottom part, is represented by Lh, and wherein a width is represented by W. A space 13b for capturing the air bubbles is provided above the outflow port 13a. The air bubbles are brought into the condition of floating at the height Ly or above while flowing along the passage length Lx. Thus, when the air bubbles flow from the upstream side of the air trap 13, the air trap 13 captures the air bubbles by making the air bubbles float in the space 13b by the time the air bubbles reach the outflow port 13a.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
