Abstract

PURPOSE:To prevent the inflow of air bubble into a printing head by means of an air trapping chamber having a porous member and an ink channel inside provided in an ink passage in an ink jet recorder. CONSTITUTION:As an ink 25 in a cartridge 18 is consumed, air flows in from an inlet 24 and is drawn into a porous member 24. However, when it moves to a head 11 for some reasons and reaches a capillary tube 20, the resistance value will be infinite between electrodes 21 and 22. So, changes in the resistance value are detected to prevent the inflow of air into the head 11. Air bubble generated at a part closer to the head 11 from the electrode 22 is blocked with the porous member 14 and accumulates in the air trapping chamber 15. As a groove-shaped ink channel 16 is provided in the air trapping chamber 15, the ink reaches the porous member 14 due to a capillary force regardless of air bubble 40 if any. Thus, the air bubble 40 will not pass through the porous member 14.
