Drop-on-demand ink jet print head |
摘要 |
An ink jet drop-on-demand print head comprises a plurality of tubular piezoelectric transducers each having two electrodes formed by an electrically conducting coating. A housing member holds the transducers in a position which includes at least one row of transducers. A substrate includes a plurality of electrical conductors, and the substrate is positioned so that each electrical conductor is adjacent one of the electrodes. A resilient connector means is provided which is not conductive along its length but is conductive across its width, and the connector means is positioned to make contact with a selected one of the electrical conductors and only one of the electrodes of one of the transducers. In a specific embodiment, the substrate comprises a flat conductor cable, and in a second embodiment the substrate comprises a printed circuit board.
