Ink collecting device in jet printer

Abstract

Abstract PURPOSE: Said device which can maintain a constant viscosity of ink and make an excellent printing by providing a detective means of ink supplying pressure change of an ink jet nozzle and a switching means of ink and its solvent. CONSTITUTION: The ink supplied from an ink supplying device is jetted from a nozzle 1 through an electromagnetic valve atomizing the ink with a supersonic oscillator 2. Dot printing is made making particles 4 reach the recording paper 6 by a charged electrode 3 and a deflected electrode 5. In this case the ink pressure change in a constant flow pump is detected using a spring 57 in a pressure accumulating room 54. According to that information an electromagnetic valve 38 is switched through an electromagnetic valve driving circuit 64 and the viscosity of the ink is adjusted by adjusting supplying volume of both the ink cartridge 36 and the solvent in a cartridge 37.
