Title: Ink jet recording head and manufacture thereof
Inventor: WATANABE TAKASHI
IPC: B41J2/045
Filed: 1989-02-03
Abstract: PURPOSE:To improve discharge speed of ink and obtain excellent printing qual ity by a method wherein a part of an orifice plate enters inside a liquid path and a discharge opening is made to have a tapered form. CONSTITUTION:After connecting a liquid path roof 3 to a substrate 1, a dry film as a material of an orifice plate 4 is connected thereto. When a heated dry film is fixed by pressure under a softened state in connecting and pressure is applied to a part becoming an orifice 5, the softened dry film enters the inside of the liquid path 6. Then, a necessary photomask is used for a top diameter of the orifice by utilizing a characteristic of the dry film being photosensitive resin, and the orifice 5 is worked in a photolitho process by exposure and development. When exposure time is varied at that time, a taper angle of the orifice can be varied. Further, a recording head can use an electrothermal conversion element generating thermal energy can be used in order to discharge ink. Since the orifice is interconnected with the liquid path in an ideal form for this recording head, a flow of the ink becomes smooth.
