Abstract

PURPOSE: To restore an ink injection nozzle by a system wherein a back flow passage having a back flow pump and a filter is provided in order to allow the clog developed in the ink injection nozzle to back blow with the ink from the nozzle to the bypath.
CONSTITUTION: A back flow passage 15 is slidably moved on the front plate 4-1 to an upward arrow direction so as to allow the back flow port 10 to connect with the nozzle 4 point for stopping the ink filled in the ink tank 3 by changing-over the valve 11. Further, the ink filled in the back flow passage 7 is transferred to the back flow part 10 by operating the back flow pump 9, the ink whereof is back flowing to the back flow passage located at the passage 2 by communicating the flow-way groove 5 with the ink chamher 2' from the nozzle 4. A clog (dust 6 or the like) of the nozzle 4 is forcibly flowing to the arrow direction to permit the dust 6 causing a clog or the extracted substance to remove through the valve 11 located at the passage 2, and removed by a filer 8.
