ABSTRACT:
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.
