  • Patent number: 9180671
    Abstract: A liquid ejecting apparatus includes a main body in which an opening portion exposing at least a portion of a carriage moving area, a cover section displaceable with the main body, an ink tank that is located outside the main body, an ink supply tube for supplying ink from the ink tank to a head, and a spacer that forms a gap between the main body and the cover. An accommodation section is configured by a casing portion formed to protrude in a discharge direction of paper. An operation panel section is configured by a casing portion exhibiting an inclined surface. The spacer forms a gap having a size that does not shut off at least an ink flow path of the ink supply tube and passes the ink supply tube through the formed gap.

  • Patent number: 8991971
    Abstract: A liquid ejecting apparatus includes a housing and a movement region of a carriage including a liquid ejecting head, an ink tank positioned at the outer side of the movement region of the carriage, an ink supply tubes connecting the ink tank and an adapter on the carriage, and a fixing portion fixing a portion of the ink supply tubes. In the housing, a containing unit of a sheet feeding cassette is formed to project to a discharge direction of a sheet and an operation panel unit is configured to have a housing portion having an inclined surface whose lower side further projects to the discharge direction than the upper side. The ink supply tubes have a deformable moving unit performing a movement of the carriage on a portion of a liquid ejecting head side rather than a fixing portion using a fixing tool.

  • Publication number: 20140043409
    Abstract: A liquid ejection apparatus includes a cover unit that is movable relative to a housing, an ink tank provided outside the housing in a state containing ink, a ink supplying tube in which ink can flow so that ink is supplied from the ink tank to the liquid ejection head, and an insertion hole that allows the ink supplying tube to be inserted into the housing, wherein the housing is formed by a housing portion in which a container that houses a stacker is formed to protrude, and a housing portion which has an operation panel having an inclined surface which protrudes at a position above the container, and the insertion hole is provided on at least one of the housing and the cover unit.

  • Patent number: 7204577
    Abstract: A liquid ejecting head is operable to move in a first direction. A platen is opposed to the liquid ejecting head to support an object to which a liquid droplet is ejected from the liquid ejecting head and to define a gap between the liquid ejecting head and the object. The platen is formed with a groove hole to which a liquid droplet deviated from an edge of the object is disposed, and through holes formed in a bottom portion of the groove hole and arranged in the first direction. A tray member is arranged below the platen to receive liquid dropped through the through holes. A first liquid absorber is provided in the groove hole. A second liquid absorber is provided in the tray member. At least one liquid leading member extends through at least one of the through holes to lead liquid absorbed by the first liquid absorber to the second liquid absorber.
