Abstract

PURPOSE:To obtain the said apparatus with high performance and excellent maintenance by connecting an ink injecting hole with one of passes perpendicular to each other at the neighborhood of a jet nozzle and providing the other for a connecting hole to the atmosphere. CONSTITUTION:The ink supplied from a supplying inlet 17 is allowed to be filled from a fine pass 16 into both a nozzle 15 and a connecting part 18 to the open air and furthermore from an ink tank 14 into a fine and long pass 19. Although foams are generated they can be removed easily by the nozzle 15 or the pass 19. If the liquid pressure of the ink in the tank 14 is increased, the impeadance of the pass 19 is so large that most of the ink is jetted efficiently out of the nozzle 15 with a smaller impeadance. The ink, after it is jetted, is supplied through the pass 16 laid at the neighborhood of the nozzle 15 and the response frequency of the ink jet can be improved.
