摘要： An ink-jet recording apparatus, it is possible to assuredly execute replenishment of ink into an ink tank and control of a pressure within the ink tank during ink replenishment by a simple configuration, and reduce the size and the weight of the apparatus, and improve reliability of the apparatus. The ink-jet recording apparatus includes an ink tank for receiving ink from an ink intake, an ink supply unit for receiving ink from a replenishing tank into the ink tank by a negative pressure introduced from a suction port of the ink tank in the inside of the ink tank, and a negative-pressure controller for causing the negative pressure within the ink tank to remain in an ink supply channel from the replenishing tank to the inside of the ink tank, so that the negative pressure within the ink tank does not return to an atmospheric pressure while receiving ink.

摘要： A printing apparatus configured to perform printing by supplying an ink from a main tank to a sub tank and ejecting the ink in the sub tank from a printing head is allowed to execute an agitating operation to appropriately eliminate sedimentation of a pigment component without being complicated in structure and increased in cost. The printing apparatus includes a diaphragm provided in an ink supply path, and a driving mechanism for driving the diaphragm to thereby change an internal volume thereof. In the ink supply path, a resistance value of a flow path from the diaphragm to the printing head is set greater than that of a flow path from the diaphragm to the sub tank. The diaphragm is driven to generate bidirectional ink flow between the diaphragm and the sub tank to eliminate pigment component sedimentation at a bottom of the sub tank.

摘要： An ink jet printing apparatus having reduced manufacture costs is provided. The ink jet manufacturing apparatus includes a diaphragm section configured to be able to change the volume of a subtank, and an atmosphere communication port configured to allow the interior of the subtank to communicate with the atmosphere. The ink jet printing apparatus further includes an atmosphere communication valve configured to be able to close the atmosphere communication port, and a driving mechanism configured to drive the diaphragm section and the atmosphere communication valve. The driving mechanism opens the atmosphere communication port and then reduces the volume of the diaphragm section. The driving mechanism subsequently allows the atmosphere communication valve to close the atmosphere communication port and then increases the volume of the diaphragm section. The driving mechanism thus supplies the ink accommodated in a main tank to the subtank.
