Abstract

PURPOSE:To provide an ink supply device which prevents the retention of ink for an ink jet printer by introducing the ink from an ink pressurizing pump into an accumulator from above. CONSTITUTION:Ink from an ink pressurizing pump 10 is introduced from a hole 20a through a tube 26 to the top of a case 22 and is introduced from above into the case 22. The ink is exhausted from a hole 20b formed at the bottom, and is fed through a solenoid valve 12 toward an ink jet heat. Since the ink is introduced from above to the case 22, it can prevent the retention of the ink, thereby preventing the deterioration of the quality of the ink.
