    摘要: An ink-jet recording apparatus capable of efficiently performing a pressurization recovery operation on a recording head without causing clogging due to dust particles. An ink supply system for supplying ink to the head includes an ink container with an air space defined above the ink surface, and a pump for pressurizing air within the air space, which pump is arranged to connect the air space with either the pressure side of the pump or the atmosphere. In one embodiment, the ink container compriss a main ink tank, and an auxiliary ink tank, having the air space, provided between the head and the main ink tank. The main ink tank is controlled to maintain a predetermined pressure head of ink therein, and the auxiliary ink tank is positioned such that the auxiliary ink tank can have, under atmospheric pressure, substantially the same pressure head as the main ink tank. In another embodiment, a removable ink cartridge, serving as the ink container, is divided into small and large ink chambers. Thus, in either case the pump need only pressurize a small volume of air in the ink container so that, during a recovery operation, the air pressurized by the pump efficiently pressurizes the ink within the auxiliary ink tank or small ink chamber even when the amount of ink has decreased.

    摘要: A printer in which an inkjet recording head is scanned with relation to a printing medium includes an ink supply member to be connected with a reserving portion arranged within the recording head when the inkjet recording head is positioned at the end portion of a scanning area, and a suction member for providing a suction power in introducing inks from the ink supply member to the reserving portion. Associated with a movement of the inkjet recording head to the end portion, those members are connected to the inkjet recording head at a different time. Herewith, in comparison with the case where those members are connected to the inkjet recording head at the same time, a force for moving the inkjet recording head required for such connection is reduced to achieve a downsizing of a driving source for generating the movement.

    摘要: A recording apparatus includes a recording-head replacing portion, a feeding unit that feeds a recording sheet, and an eject unit that ejects the recording sheet on a front side of the apparatus. The apparatus further includes a head mount that is movable between the carriage and the head-replacing portion while the recording head is mounted on the head mount, a head-lowering member that moves the recording head from the carriage to the head mount, and a head-pushing member that moves the recording head mounted from the head mount to the carriage.
