LIQUID JET HEAD AND RECORDER MOUNTING IT

摘要

PROBLEM TO BE SOLVED: To provide an inkjet print head and an inkjet printer having a corrosion resistant filter part in which a small hole for passing ink is formed while keeping some open area rate. SOLUTION: Groove-like or rectangular recesses are formed by etching the surface or the rear of a thin stainless steel plate and a through hole is made at the overlapping part thus constituting the filter part. An open area rate is set appropriately by adjusting the pitch of the grooves or the interval of the rectangles. COPYRIGHT: (C)2004,JPO
