Document Type and Number:
Japanese Patent JP3454833
Kind Code:
B2
Abstract:
An ink-jet printing head according to the present invention is constituted so that two reservoirs 3 and 4 are formed with each pressure generating chamber 2 between the two reservoirs, the pressure generating chamber 2 communicates with at least one reservoir 3 or 4 via an ink supply port 5 or 6, adjacent nozzle communicating holes are arranged in approximately opposite positions with the center in the longitudinal direction of the pressure generating chamber 2 between the adjacent nozzle communicating holes and arranged zigzag with the adjacent nozzle communicating holes shifted in the longitudinal direction of the pressure generating chamber 2 and the height M of a partition for partitioning the nozzle communicating hole 7 or 8 which is a through hole and the adjacent pressure generating chamber 2 is approximately equal to the height of a partition N between the pressure generating chambers 2. Hereby, even if the pressure generating chambers are arranged in high density, crosstalk caused by the partition for partitioning the nozzle communicating hole and the adjacent pressure generating chamber can be prevented.
