20080231653 | IMAGE FORMING APPARATUS - A disclosed image forming apparatus includes an apparatus main body; a page-width inkjet head unit capable of ejecting fluid droplets without substantially moving the page-width inkjet head unit while forming an image on a medium to be recorded on; a maintaining and recovering unit maintaining and recovering a function of a nozzle of the page-width inkjet head unit; and an engaging unit for engaging the page-width inkjet head unit and the maintaining and recovering unit together as a single unit when the page-width inkjet head unit and the maintaining and recovering unit are removed from the apparatus main body as a single unit. | 09-25-2008 |
20090128597 | Image forming apparatus - An image forming apparatus comprises a body, an engine part provided in the body and including a recording head that ejects droplets of a recording liquid, the engine part recording an image on a recording medium by the recording head while feeding the recording medium in a main scanning direction, a medium discharging part provided in the body at a side of the engine part, the medium discharging part feeding the recording medium to a medium take-up part after recording of the image with the engine, and a cartridge loading part that holds a cartridge of the recording liquid in a detachable manner, the cartridge loading part being provided in the body of the image forming apparatus and feeding the recording liquid to the recording head of the engine part, wherein the cartridge loading part is provided underneath the medium discharging part. | 05-21-2009 |
20090273134 | Automatic original conveying device and image forming apparatus - In an automatic original conveying device, a motor rotates in a single direction and a driving force transmission mechanism transmits the driving force of the motor from a sheet feeding roller to a switchback roller. The sheet feeding roller conveys an original that stands by in a switchback conveying path to a second conveying path. A sorting unit sorts the original conveyed from a paper delivery path to an original delivery table or to the switchback conveying path. The switchback roller is provided between the sorting unit and the switchback conveying path and it is rotatable in a normal direction or a reverse direction. | 11-05-2009 |
20100149299 | IMAGE FORMING APPARATUS - An inkjet recording apparatus provides an improved printing speed and improved convenience of use. A recording head discharges droplets of a recording liquid onto a paper so as to form an image on the paper. A belt conveyance mechanism has a belt onto which the paper is electrostatically attached. The paper attached onto the belt is conveyed in a direction perpendicular to a carding direction of the paper. | 06-17-2010 |
20110285078 | Automatic sheet feeder - An automatic sheet feeder includes a sheet setting unit to set a sheet to be fed by a sheet feeding member, an openably closable cover rotatably disposed over an upper portion of the sheet setting unit, a sheet detector rotatably supported on the cover to detect whether or not a sheet is set on the sheet setting unit and including a detection member, a rotary shaft about which the detection member rotates, and a sensor to detect the setting of the sheet according to a movement of the detection member, and a rotating member to cause the detection member to rotate in a direction such that an angle between a line extending in a longitudinal direction of the detection member and a surface of the sheet set on the sheet setting unit decreases as the cover rotates from an open position to a closed position. | 11-24-2011 |
20120104676 | Automatic document feeder and image forming apparatus including the same - An automatic document feeder includes an upstream conveyance roller pair disposed upstream of an image reader including an upstream driving roller and an upstream driven roller; a downstream conveyance roller pair including a downstream driving roller and a downstream driven roller; an upstream auxiliary roller pair including upstream auxiliary rollers disposed coaxially on a shaft of the upstream driving roller and of the upstream driven roller, respectively, each formed of an elastic member and having a diameter greater than that of the adjacent upstream driving roller and of the adjacent upstream driven roller, respectively; and a downstream auxiliary roller pair including downstream auxiliary rollers each disposed coaxially on a shaft of the downstream driving roller and of the downstream driven roller, formed of a low-hardness elastic member and having a diameter greater than that of the adjacent downstream driving roller and of the adjacent downstream driven roller. | 05-03-2012 |
20130222826 | SHEET CONVEYANCE UNIT, IMAGE READING DEVICE, AND IMAGE FORMING APPARATUS - A sheet conveyance unit including a sheet tray on which a stack of sheets is placed, a sheet feed member to feed sheets from the stack of sheets, a separation/feed unit to separate a topmost sheet from the rest of sheets fed by the sheet feed member and feed the topmost sheet to a predetermined position, and a pre-separation unit disposed between the sheet tray and the separation/feed unit. The pre-separation unit includes a downward sloped portion to guide a leading edge of each sheet diagonally downward, and an upward sloped portion provided downstream from the downward sloped portion in a conveyance direction of the sheets to guide the leading edge of each sheet diagonally upward. Both ends of the upward sloped portion in a lateral direction are sloped upward more gently than the center of the upward sloped portion. | 08-29-2013 |
20130335790 | IMAGE SCANNER AND IMAGE FORMING APPARATUS INCORPORATING SAME - An image scanner includes a stationary original plate on which a stationary original is placed and a moving original plate, over which a moving original is conveyed, aligned with the stationary original plate in a sub-scanning direction and tilted relative to the stationary original plate by a given angle. A reader is movable in the sub-scanning direction between a stationary original reading span disposed opposite the stationary original via the stationary original plate to read an image on the stationary original and a moving original reading position disposed opposite the moving original via the moving original plate to read an image on the moving original. The reader pressingly contacts the stationary original plate and the moving original plate as the reader moves in the sub-scanning direction. | 12-19-2013 |
20140347711 | IMAGE SCANNER AND IMAGE FORMING APPARATUS INCORPORATING SAME - An image scanner includes a stationary original plate on which a stationary original is placed and a moving original plate, over which a moving original is conveyed, aligned with the stationary original plate in a sub-scanning direction and tilted relative to the stationary original plate by a given angle. A reader is movable in the sub-scanning direction between a stationary original reading span disposed opposite the stationary original via the stationary original plate to read an image on the stationary original and a moving original reading position disposed opposite the moving original via the moving original plate to read an image on the moving original. The reader pressingly contacts the stationary original plate and the moving original plate as the reader moves in the sub-scanning direction. | 11-27-2014 |
