  • Patent number: 8439482
    Abstract: A cartridge comprises an ink supply structure, a terminal bearing structure, and a first restriction portion. The terminal bearing structure has terminals arranged in a terminal plane which is neither parallel nor perpendicular to a plane defined by a mounting direction leading edge of the ink supply structure, so that the contact portions of the terminals receive a force in a direction opposite from the mounting direction. An engagement portion of the first restriction portion is provided at a position adjacent to the terminal bearing structure.

  • Publication number: 20120081448
    Abstract: A liquid ejecting apparatus includes a movable head with nozzles that eject a liquid; a transport unit that transports a medium in a transporting direction; and a sensor that detects an edge of the medium and that is movable with the head. Ejection of liquid from the nozzles is controlled based on the sensor detection result. The transport roller transports the medium in a slanted manner toward a surface of a platen, and after the medium's front edge contacts the platen, the medium bends on the platen with the front edge of the medium moving along the surface of the platen toward a paper discharge roller. Relative to the transporting direction, the sensor is positioned upstream of the most upstream nozzle and downstream of a position at which the front edge of the medium first comes into contact with the platen.

  • Patent number: 8061798
    Abstract: The present invention relates to a liquid ejecting apparatus including: a movable head provided with a plurality of nozzles for ejecting a liquid; a carry unit for carrying a medium in a predetermined carrying direction; and a sensor for detecting an edge of the medium, the liquid ejecting apparatus controlling ejection of the liquid from the plurality of nozzles in accordance with a result of the detection of the sensor. In this liquid ejecting apparatus, the position, in the carrying direction, of the sensor is at the same position of or on an upstream side of a nozzle located most upstream in the carrying direction, of among the plurality of nozzles. In this way, it is possible to arrange the sensor for detecting the edge of the paper at the most suitable position, and to suppress waste of ink that is ejected from the nozzles.
