Abstract

PURPOSE:To smooth ink jet and supply by specifying the structure of a print head. CONSTITUTION:Pressure chamber 15 having a diameter reduced with approaching outflow path 20 of very small hole, and ink supply chamber 16 surrounding this are installed in print head 14, and thin ink supply clearance 18 connecting both the chambers is blocked with metal diaphragm 17. A disk of piezoelectric crystal 19 is attached to diaphragm 17, and ink supply tube 23 surrounded with cylindrical piezoelectric crystal 24 is connected with chamber 16. On applying voltage to crystals 19 and 24 at some interval, diaphragm 17 bends, resulting in shrinking tube 23, ejecting the ink in chamber 15 smoothly through path 20, as well as supplying the ink into chamber 15 smoothly.
