Abstract
An ink jet printer recording head in which a plurality of vibrating plates made of a piezoelectric material are fixedly spaced from a nozzle plate such that the small gap therebetween admits a portion of ink. The surface of each vibrating plate is integrally provided with a pair of positive and negative comb-type electrodes. By applying a voltage across these comb-type electrodes, the vibrating plates are bent toward the nozzles to pressure the ink and attendantly eject the ink through the nozzles in the form of ink droplets on a recording sheet.
