INK JET UNIT, INK TANK, ATTACHMENT AND DETACHMENT OF INK TANK TO INK JET UNIT AND INK JET RECORDING APPARATUS

摘要

PURPOSE:To reduce the occupying vol. of an ink jet unit and the connection space with a recording head by mounting an ink tank on the ink jet unit perpendicularly to the direction of movement of a carriage and using the lower side of the ink tank insertion part of a housing as a guide part to execute the rotary attachment and detachment of the ink tank with respect to the housing. CONSTITUTION:An ink tank 21 is inserted in the ink tank insertion part being the opening between the housing 103 and front plate 113 of an ink jet unit by pinching the vicinity of the knob of the ink tank 21. At this time, the upper side part 114 of the front plate 113 is set to a guide part and a part of the ink tank is brought into contact with the guide part (P1) and the lower corner part of the ink tank collides with the side surface of the housing 103 (P2). The lower corner part of the ink tank revolves around P1 while gradually slides downwardly to set the ink tank to a predetermined state. The lower corner part of the ink tank is further slid downwardly to set the ink tank to a state III.
