摘要： An inkjet head system has an inkjet head and a printed board connected to the inkjet head. The inkjet head includes a cavity plate formed with a plurality of ink pressure chambers arranged adjacent to each other. A piezoelectric actuator is placed on the cavity plate. A plurality of driving electrodes is formed on the piezoelectric actuator at positions corresponding to respective ones of the plurality of ink pressure chambers. The printed board includes a plurality of electrode lands connected with respective ones of the plurality of driving electrodes to supply driving signals thereto. The electrode lands are connected with respective ones of the plurality of driving elements by means of magnetic force. Therefore, the printed board can be easily detached from the inkjet head by pulling it from the inkjet head against the magnetic force.

摘要： A cavity plate for an ink-jet printhead includes a base material and a chamber sheet. An ink channel array constituting ink chambers is provided through the chamber sheet by a wire electric discharge machine, while an ink reservoir is formed on the base material by a wire electric discharge machine. Then, the chamber sheet and the base material are bonded to one another. Nozzles to eject ink may be created on a nozzle sheet, which is later connected to the chamber sheet. Alternatively, the nozzles may be directly provided on the chamber sheet. Thus, the cavity plate is provided having the ink chambers and the ink reservoir with high precision, without the increase in the production cost.
