  • Publication number: 20130285311
    Abstract: A sheet ejection device includes a plurality of second sheet abutting members and a plurality of conductive members. Each second sheet abutting member has a non-conductive sheet regulating surface that abuts on a rear end portion in an ejecting direction of each sheet on a sheet output tray to regulate movement thereof. Each conductive member is attached at a position lower than a sheet drop height position and in the vicinity of each second sheet abutting member in a grounded state in the sheet width direction. Each conductive member attracts a rear end portion in the ejecting direction of a sheet on the uppermost layer of a plurality of sheets stacked on the sheet output tray, up to the sheet drop height position on the sheet regulating surface of the second sheet abutting member.

  • Patent number: 8376355
    Abstract: In a sheet discharge device, sheets are sequentially discharged by a sheet discharge roller with a leading end of each of the sheets in the lead in a sheet discharge direction and stacked on a sheet receiving tray inclining relative to a vertical direction. A sheet reverse member is disposed at such a position relative to the sheet receiving tray and the sheet discharge roller that a trailing end of a first sheet discharged by the sheet discharge roller reaches the sheet reverse member before a leading end of a second sheet discharged subsequently to the first sheet collides with the first sheet when a sheet time interval between the trailing end of the first sheet and the leading end of the second sheet is set to a minimum sheet time interval available in continuous sheet discharge in the sheet discharge device.

  • Publication number: 20070263244
    Abstract: To meet a demand for changing a print medium size, particularly for increasing the size of print medium while at the same time satisfying the demand for higher printing speed. To that end, a plurality of printer units (116), which are spatially independent of each other (separate from each other) and also independent in the signal system and the ink system, are arranged in an appropriate layout to allow for a line-sequential printing. An information processing device (100) divides a generated image into a plurality of pieces of print data and transfers them to the plurality of printer units. A transport device (117) is installed to feed a large-sized print medium to an area where the plurality of printer units are arranged. The transport device transfers to each of the plurality of printer units a print timing signal corresponding to the position of each printer unit.

  • Patent number: 6945635
    Abstract: A liquid discharging method for a liquid head discharge head. The head has discharge ports, liquid flow paths, bubble generating areas, bubble generating means, liquid supply ports connecting the flow paths with a common liquid supply chamber, and a movable member in the flow paths supported with a minute gap to the supply ports. The area of the movable member surrounded at least by its free end and both sides continued therefrom is larger than the opening area of the supply ports. The method includes the step of setting a period for the movable member to substantially close the opening area during the period from the application of a driving voltage to the bubble generating means to the substantial termination of isotropical growth of the entire bubble by the bubble generating means. Growth of the bubble component in the direction opposite the discharge port can be suppressed, improving liquid refill.
