Recording head

Abstract

Abstract PURPOSE:To provide a recording head which is capable of recording in stable manner while reducing production of noises considerably, by connecting an electric- mechanical converting means and a liquid ejecting orifice member with each other in the manner that radial contraction of the electric-mechanical converting means at its end portion is not restricted, and ejecting liquid to the outside in the form of liquid particles or drips. CONSTITUTION:A recording head of this invention comprises a liquid ejecting orifice member 2 formed with an orifice 3 and an electric-mechanical converting means 4 for changing the volume of liquid chamber 5 so as to eject liquid in the liquid chamber 5 from orifice 3 and to thereby form liquid particles or drips. The electric- mechanical converting means 4 is connected with a liquid supplying portion and a liquid supply pipe 6. Since, in the above arrangement, orifice member 2 and supply pipe 6 are fitted directly to the electric-mechanical converting means 4, it is enabled to transmit vibrational energy of means 4 highly efficiently to liquid and to produce liquid particles or drips in efficient and stable manner.
