Title: Ink jet recording head, ink jet head cartridge and recording apparatus having the recording head
Inventor: UCHIKATA YOSHIRO
IPC: B41J2/175
Filed: 1993-01-19
Abstract: PURPOSE:To prevent possible leakage of ink during replacing an ink tank and discharge failure due to the increase of ink viscosity by the use of a recording head having a liquid discharge part and a flow path combination part and an ink jet recording apparatus having a filter part provided on the end of the flow path combination part. CONSTITUTION:When an ink tank 2 and a recording head 1 are separated one to another, a valve 4 acts to block off the ink supplying port 11 through spring 5 so as to prevent the leakage of ink from the tank 2, and when the tank 2 and head 1 are in contact with each other, ink within the tank 2 is introduced to the head 1, and the inner wall of the supplying port 11 comes into close contact with the outer surface of an ink supplied port 10 in order to prevent the leakage of ink. Also, in the case where the head 1 is single, and Impacts such as vibration or dropping take place, leakage of ink is not likely to happen by the surface tension and flow resistance of a filter part 3. As the head 1 is left as a unit, ink exposed in the atmosphere becomes small by the filter 3 in a connecting part of the head and ink tank, thus an evaporating quantity of ink can be decreased, resulting in restraining the discharge failure of the head 1 due to increase of ink viscosity.
