Abstract

PURPOSE:To enable the stable emission of ink, by providing a moving plate having the almost same number of holes as nozzles to the leading end parts of the nozzles and using said holes as the orifice parts of an ink jet head and providing a new orifice part to the nozzle part if necessary. CONSTITUTION:A moving plat 12 having a large number of orifices 10 is places on an ink jet head 13 and each nozzle 20 of the ink jet head 13 coincide with each orifice of the moving plate 12. An ink particle 15 is emitted to the direction shown by the arrow 17 through each orifice 10. When the orifice 10 during use is clogged by dust or the coagulation of ink as shown by the numeral 19, the moving plate 12 having the orifices 10 moves and the new orifice 10 is issued to the nozzle surface. By this method, the emission of the ink is again enabled. By variously changing the size of each orifice 10, the size of an image dot can be arbitrarily changed.
