Abstract

PURPOSE:To stabilize an ink injection condition and improve reliability of the ink injection by preventing from adhering the dust in the atmosphere and preventing from drying the ink by a method wherein an orifice is covered with the ink of the ink reservoir located at the point of the orifice. CONSTITUTION:A slit plate 10 is provided for the point of the orifice 6 so as to permit the ink reservoir 11 to form corresponding to the axial line (flow direction) of the orifice 6. On non-operating condition, the static force within the ink chamber 5 and the ink surface tension force of the ink reservoir 11 are balanced without outflowing the ink for compressing the ink through the feed passage 7 for maintaining the normal condition. On recording time, the vibrator 8 is operated in order to reduce the inner volume of the ink chamber 5 corresponding to the electric signal to allow the pressure increase within the ink chamber 5 to transmit to the ink level of the ink reservoir 11 aligned with the orifice 6 for injecting the ink drop forwardly. On recovering the vibrator 8 to the original position, the ink is replenished through the feed passage 7.
