PURPOSE:To provide an ink printing apparatus which permits simultaneous multidot record and having high density of nozzle arrangement and which comprises pressure element in an ink passage connecting to a plurality of nozzle arranged in direct line. CONSTITUTION:Electric conductive narrow pipes 11, 12, 13 ... are arranged in direct line by its one end and fixed to a synthetic resin base 3 and first group of the narrow pipes 11, 13, 15 ... are folded in right angle so as to widen space between each adjacent narrow pipes and first group of pressure elements 21, 23, 25 ... as piezo element and second group of pressure elements 22, 24, 26 ... are arranged in projecting manner to the space. A back side electrode 5 is aranged in opposition to the surface on which a nozzle 4 of the base 3 and recording paper 6 is arragned. |
