Abstract
An ink supply pipe 70 is inserted into a sponge 44 to reach a central or lower portion thereof where ink density higher. Thereby, the ink can be fed stably to a nozzle 42 and to reduce influence of the air introduced through an ink supply tube 60 and an ink supply pipe 70. Lateral holes 72 for ink discharge are provided on a side wall of the ink supply pipe 70. Thereby, a sufficient amount of the ink can be supplied from the lateral holes 72 of the supply holes 70, even when the sponge 44 is crushed upon insertion of the ink supply pipe 70 to narrow the tip orifice of the ink supply pipe 70.
