摘要： The invention prevents drawbacks resulting from the bubble generated at the downstream side of the filter, while minimizing the waste in the ink. The recording head has a sub tank for storing ink supplied from the exterior, and a liquid chamber storing the ink supplied from the sub tank and supplying ink directly to a nozzle for ink discharge. A filter is provided between the sub tank and the liquid chamber. The liquid chamber holds ink of a predetermined amount in such a manner that the ink therein is separated by gas between the filter and the liquid chamber.

摘要： An ink jet recording apparatus comprises a recording head including a discharge port for discharging ink, a first liquid chamber at the upstream side in the direction of ink flow toward the discharge port, and a second liquid chamber at the downstream side, an ink tank for containing ink to be supplied to the recording head, an ink supply tube for causing the ink tank to communicate with the recording head, a shut-off valve provided in the ink supply tube and opening or closing the ink supply tube, a cap for covering the discharge port; and a suction pump for forcedly discharging the ink in the recording head from the discharge port when the cap covers the discharge port. The shut-off valve is opened when the first and second liquid chambers are reduced to respectively desired pressures by the suction pump in a state where the cap covers the discharge port and the shut-off valve is closed, whereby the ink in the ink tank is supplied through the ink supply tube to the first and second liquid chambers.

摘要： A cap for a recording head capable of covering a nozzle of the recording head in a securely enclosed state during sucking of ink is provided for an inkjet recording apparatus. The cap for the recording head includes an elastically deformable contact section and an abutting section. When a nozzle-forming surface of the recording head is pressed into contact with the contact section so that the contact section deforms to have a predetermined amount of deformation, the abutting section abuts against the nozzle-forming surface so as to restrict the deformation of the contact section. Therefore, the contact section cannot deform excessively, enabling to properly maintain the close contact to the nozzle-forming surface and preventing ink from being dried and increased in viscosity.
