摘要： An ink jet printer head having nozzles, actuators, a multiplexer, and actuator finding circuits of a matrix method. The multiplexer is capable of single-input and multiple output. The actuator finding circuits of the inkjet printer head include electronic switches arranged in rows and columns. The nozzles have the actuators, and the actuators are controlled by the electronic switches. The multiplexer receives a signal in accordance with the conveyance direction and position of the ink jet printer head, and sequentially outputs the signal to the actuator finding circuits in accordance with the signal it received, thereby sequentially selecting a nozzle group in the rows. In this situation, when an external print data signal is inputted to the actuator finding circuits to select a nozzle group in the columns, the corresponding electronic switch drives the actuator, so that the ink is ejected out of the nozzle. Accordingly, by using the multiplexer having only one external input terminal, the increment of the number of pads is decreased when the number of ink jet printer head nozzles is increased.

摘要： A piezoelectric inkjet printhead includes a manifold, a chamber array including a plurality of chambers in connection with the manifold and arranged along at least one side of the manifold, a vibrating plate to cover the plurality of chambers, and a plurality of piezoelectric actuators formed on the vibrating plate to change pressures of corresponding ones of the plurality of chambers by vibrating the vibrating plate. The plurality of chambers includes a plurality of pressure chambers disposed in a center portion of the chamber array and having corresponding ink ejecting nozzles, and at least two dummy chambers, one disposed on each side of the chamber array and having corresponding dummy nozzles that do not eject ink. A plurality of trenches may be formed in the vibrating plate between each of the piezoelectric actuators.

摘要： An ink-jet printer head includes a base plate having ink channels penetrating through the base plate, through which ink is supplied, a hollow heat driving section formed in the base plate and encircling an exit of the ink channels, an ink chamber barrier stacked on the base plate for serving as a side wall of an ink chamber where ink is reserved, and a nozzle plate stacked on the ink chamber barrier and having a nozzle which communicates with the ink channels and the ink chamber coaxially. Accordingly, an area occupied by the unit nozzle can be reduced, and ink flow in the ink chamber is easily controlled, thereby enhancing a printing speed and a print quality.
