  • Publication number: 20100245462
    Abstract: A liquid ejecting apparatus includes a liquid ejecting head having a nozzle formation surface with a nozzle that discharges a liquid. A cleaning member wipes the nozzle formation surface to remove liquid that has adhered thereto. An absorption member of a porous material deforms under pressure and includes an absorption surface that contacts the cleaning member to absorb liquid that has adhered thereto. A pressure member moves between a pressure position, in which the pressure member applies pressure to the absorption surface of the absorption member, and a non-pressure position, in which the pressure member does not apply pressure to the absorption surface. A movement mechanism moves the pressure member from the non-pressure position to the pressure position to cause the absorption member to deform, thereby dispersing the liquid absorbed by the absorption member from the cleaning member via the absorption surface into the interior of the absorption member.

  • Publication number: 20100245498
    Abstract: A fluid supplying apparatus includes a fluid supplying passage through which fluid is supplied from a fluid supplying source, at an upstream side, toward a downstream side. A pump includes a pump chamber and a first displacement portion. A closing device closes the fluid supplying passage and includes a pressure chamber and a second displacement portion. The second displacement portion is displaced to increase or decrease capacity of the pressure chamber. The second displacement portion is displaced in a direction for decreasing the capacity of the pressure chamber in accordance with negative pressure that is applied from the downstream side of the fluid supplying passage to close the fluid supplying passage. A pressure reduction chamber is formed next to the pressure chamber and is partitioned from the pressure chamber. An opening device opens the fluid supplying passage and reduces internal pressure of the pressure reduction chamber.

  • Publication number: 20100207991
    Abstract: A liquid ejecting head for ejecting a liquid includes a cap that abuts a nozzle forming surface, thereby surrounding a nozzle. A cap holder biases the cap toward the liquid ejecting head. The cap holder can move in a first direction toward and away from the liquid ejecting head. A carrier reciprocates in a second, orthogonal direction. The carrier reciprocates in the second direction to reciprocate the cap holder in the first direction with a cam mechanism between an abutting position in which the cap abuts the liquid ejecting head and a flushing position in which the cap is spaced apart from the liquid ejecting head. The cap moves to a first flushing position when the cap moves from the abutting position to the flushing position, whereas the cap moves to a second flushing position when the cap moves from a non-abutting position to the flushing position.

  • Publication number: 20060187774
    Abstract: A recording apparatus includes: recording means having a drive part including rotational drive means for rotating an optical recording medium in order to record data onto the optical recording medium; data coding means for coding data; and recording control means for storing the coded data into storage means and controlling the recording means to record the data stored in the storage means onto the optical recording medium. The recording control means includes overall control means for controlling the recording control means overall and servo control means for servo-controlling the drive part of the recording means. In the recording-standby state standing by to store the coded data, the overall control means stops operation of the servo control means, and at the same time, servo-controls the rotational drive means.
