Abstract

PURPOSE:To obtain the recording head wherein a wall of a liquid chamber is formed by a variable form body containing a permanent magnetic material, liquid drops can be produced in high efficiency, can record sufficiently responding to the electric impulses of high frequency, the formation of a multi-orifice is easy and noises are extremely low. CONSTITUTION:A variable form body 7 is made up in such a manner that a permanent magnetic material 10 is constituted by stacking two circular magnets 12, 13 with strong magnetic force as a rate earth magnet so that polarity at the contact surface sides become homopolar, and the material 10 is wrapped with an elastic portion material 11, such as, rubber, etc. Recording head forming portion materials 14, 15 building up one portion of an inwall surface of a liquid chamber 3 and an orifice 2 are mounted to the four sides of the elastic portion material 11. A forming portion material 16 making up one portion of the inwall surface of the liquid chambr and a supply passage 6 are similarly installed, and each disposed to a forming portion material 17 building up one portion of the inwall surface of the liquid chamber tightly in the same way.
