20090109258 | LIQUID EJECTING APPARATUS, WIPING METHOD OF LIQUID EJECTING HEAD, AND PRINTING APPARATUS - An apparatus includes a liquid ejecting head capable of ejecting liquid from a plurality of ejection ports by driving a plurality of ejection energy generation elements corresponding to the plurality of ejection portions. The apparatus includes a wiping mechanism capable of wiping an ejection port face in which a plurality of ejection ports is arranged in the liquid ejecting head. The ink ejection from the plurality of ejection ports is performed in a manner of a plurality of divisions. A time interval from a last wiping to a next wiping is adjusted according to an interval of the ejection energy generating elements corresponding to an adjacent ejection port. | 04-30-2009 |
20100214343 | PRINTER - An ink jet printer includes a platen including an attraction portion for attracting a sheet and a sheet support surface in which an collection opening for collecting ink discharged outside the sheet is formed, a negative pressure generation mechanism configured to be used in common to generate a negative pressure to be supplied to each of the attraction portion and the collection opening, a first duct configured to connect the negative pressure generation mechanism and the attraction portion, a second duct configured to connect the negative pressure generation mechanism and the collection opening, and an adjustment mechanism configured to ununiformly change a negative pressure to be supplied to the attraction portion through the first duct and a negative pressure to be supplied to the collection opening through the second duct. | 08-26-2010 |
20100214346 | INK-JET RECORDING APPARATUS - An ink-jet recording apparatus includes a platen provided with a suction-collection section which sucks in and collects ink discharged deviating from an end portion of recording medium. The ink-jet recording apparatus includes a suction force generation unit for collecting ink configured to enable the suction collection section to generate a suction force, a collection flow path connecting the suction collection section to the suction force generation unit for collection, and a flow path control unit configured to vary an sectional area of the collection flow path. The sectional area of the collection flow path is varied according to an image forming time or a type of the recording medium. | 08-26-2010 |
20110182645 | CUTTING DEVICE AND RECORDING APPARATUS - A cutting device includes a conveyance unit for conveying a recording medium in a conveyance direction, a guide configured to guide a recording medium, a blade movable in a direction intersecting with the conveyance direction, for cutting the recording medium when the blade moves with a leading end side thereof inclined to the upstream side, a presser member movable to a first position where the presser member holds down the recording medium and to a second position where the presser member does not hold down the recording medium, wherein the presser member holds down the recording medium at a position separated farther than a thickness of the recording medium from the guide in the first position, and wherein the presser member holds down the recording medium at least from before the blade starts to cut the recording medium to when the blade is cutting the recording medium. | 07-28-2011 |
20130083144 | INK-JET RECORDING APPARATUS - An ink-jet recording apparatus includes a platen provided with a suction-collection section which sucks in and collects ink discharged deviating from an end portion of recording medium. The ink-jet recording apparatus includes a suction force generation unit for collecting ink configured to enable the suction collection section to generate a suction force, a collection flow path connecting the suction collection section to the suction force generation unit for collection, and a flow path control unit configured to vary an sectional area of the collection flow path. The sectional area of the collection flow path is varied according to an image forming time or a type of the recording medium. | 04-04-2013 |
20130135698 | READING APPARATUS AND PRINTING APPARATUS - A pressing unit configured to press a supporting surface for supporting a sheet, and a carriage configured to hold a sensor unit and to move on the pressing unit are integrated into one unit. There is provided a movement mechanism configured to move the unit between a first position in which the pressing unit presses the supporting surface during reading and a second position in which the pressing is released during movement of the sheet on the supporting surface. | 05-30-2013 |
20150328906 | SHEET FEEDING APPARATUS AND PRINT APPARATUS - A sheet feeding apparatus is provided which restrains a borne rolled sheet from being deflected to allow the sheet to be reliably fed. A sheet feeding apparatus includes a holder configured to hold a rolled sheet so as to be rotated; and a rotator configured to bear an outer periphery of the rolled sheet held by the holder from below in a direction of gravity, the rotator rotates with the rolled sheet while feeding. | 11-19-2015 |
20160136980 | SHEET SUPPLYING APPARATUS AND PRINTING APPARATUS - A sheet can be securely drawn out of a sheet roll irrespective of an outer diameter of the sheet roll, and then, can be conveyed. A driven roller moves according to the outer diameter of the sheet roll, so as to be brought into press-contact with an outer periphery of the sheet roll from under in a gravity direction irrespective of the outer diameter of the sheet roll. An arm member moves according to the outer diameter of the sheet roll, so as to guide a lower side of the sheet drawn through above the driven roller irrespective of the outer diameter of the sheet roll. | 05-19-2016 |
