Abstract: The printer assembly 60 of the image-forming apparatus 20 has a right side plate 200R and a left side plate 200L apart-at a predetermined distance in the sheet width direction (arrow-W direction) perpendicular to the delivery direction of the cut paper sheet P (arrow-A direction and arrow-B direction in FIG. 2). A first delivery pathway and a second delivery pathway are placed between the right side plate 200R and the left side plate 200L (in the space between the side plates). Two openings are formed on the right side plate 200R. The space between the opening 201 and the left side plate 200L serves as the first printer-unit room 81 for placing the printer unit 91. The space between the opening 202 and the left side plate 200L serves as the second printer-unit room 82 for placing the printer unit 92.

Abstract: In a recording apparatus for stably conveying a recording medium to a recording portion by a convey belt, the recording medium is passed through a nip of a pair of separation supply rollers and enters into a nip between a convey belt and a driven roller and thereafter is conveyed by the convey belt to a recording portion. When a leading end of the recording medium is detected by a recording medium detect sensor, the supply roller is disengaged from the separation roller, so that the convey belt is not subjected to the influence of the pair of separation supply rollers via the recording medium and when a trailing end of the recording medium is detected by a recording medium detect sensor, the driven roller is disengaged from the convey belt, so that the recording medium is not subjected to conveyance resistance from the driven roller.

Abstract: A sheet feeding device is provided with a sheet feeding unit for feeding sheets supported on a sheet support means, and sheet separator means provided downstream of the sheet feeding unit with respect to the sheet feeding direction, the sheets fed by the sheet feeding unit being separated one by one by the sheet separator and fed. The sheet separator is comprised of an inclined surface against which the sheet fed by the sheet feeding unit abuts, a dash member provided downstream of the inclined surface with respect to the sheet feeding direction and against which the leading end of the sheet riding over the inclined surface abuts, and a resilient member for displaceably supporting the dash member when the sheet abuts against the dash member.

Abstract: The present invention provides an image forming apparatus with an image forming device, sheet containers, sheet discharge unit for discharging the sheet on which the image was formed onto the stacking tray, convey path for directing the sheet to the image forming device, switching unit for selectively directing the sheet to the discharge unit or the convey path and for directing the sheet from the convey path to the discharge unit, and convey rollers for conveying the sheet along the convey path means toward a direction extending from the switching unit to the image forming device or an opposite direction.

Abstract: An image forming apparatus, in which sheets on which image formation has been effected are once contained in an intermediate tray for second image formation and the sheets contained in the intermediate tray are re-fed to an image forming portion of the image forming apparatus to thereby effect plural times of image formation on a sheet, is characterized by a counting device for counting the sheets contained in the intermediate tray.

Abstract: A sheet-postprocessing apparatus includes a sheet discharger which discharges sheets to a stacker, the stacker including a first tray adjacent to the discharger for supporting trailing portions of the sheets discharged by the discharger and a second tray for supporting leading portions of the sheets, the second tray being movable in a vertical direction and disposed downstream of the first tray with respect to a sheet discharge direction, the trays being inclined so that sheets stacked thereon slide by their own weight, such that a stack of sheets supported on both trays are stapled by a stapler, the stapled set of sheets then being pushed out of the first tray to be stacked entirely by the second tray. The sheet post-processing apparatus operates in two modes, a stapling mode and a non-stapling mode wherein sheets discharged by the discharger bypass the first tray and are supported entirely by the second downstream tray.

Abstract: The present invention provides an image forming apparatus having an image forming device for forming a non-fixed image on a recording sheet, a fixing rotary member for fixing the non-fixed image to the recording sheet, a containing portion for containing the recording sheet to which the image was fixed by the fixing rotary member, a re-feeding device for re-feeding the recording sheet contained in the containing portion to the image forming device, and a coating device for coating a parting liquid to the fixing rotary member.

Abstract: The present invention provides a sheet sorting apparatus with plural bins trays; bin tray moving device for moving the bin trays stepwise to cause each of the bin trays to face a sheet receiving position; and a controller for controlling the operating speed of the bin tray moving device according to sheet transporting information of an image forming apparatus to be connected to said sorting apparatus, in such a manner that said bin tray moving means can be operated in continuous manner even during the discharge of a sheet into a bin tray.

Abstract: A sheet post-processing apparatus includes plural trays arranged along a sheet conveyance direction, wherein a sheet is stacked, bridging between the plural trays, wherein a post-processing is effected to the sheet in a part of the plural trays; a controller for controlling the trays to provide a level difference between the trays by lowering another one of the trays than the one of the trays; and aligning device for laterally aligning the sheet stacked, bridging between the trays providing the level difference.
