Abstract

PURPOSE:To ensure a recording operation by using a low driving voltage by a method wherein an ink is fed into the ink chamber when a vibrator is deformed in order to enlarge the ink chamber volume, and the ink is particled to inject by the elastic retaining force of the vibrator. CONSTITUTION:An electric signal is entered into a vibrator 8 from the balanced condition between the static force within the ink chamber 5 and the ink surface tension of the orifice 6 point so as to allow the internal volume of the ink chamber 5 to increase by deforming outwardly. The ink is fed to fill the increased volume of the ink chamber 5 by flowing through the feed passage 7. Further, on shutting down the electric signal, the deformed vibrator 8 is recovered to the original normal condition with the elastic force thereof. Accordingly, the ink filled in the ink chamber 5 is compressed by the vibrator 8, allowing to inject a single or a number of ink small drops from the orifice 6 point, permitting to reach a recording paper.
