Abstract: A sheet handling device including a sheet transport path, a transport mechanism adapted to advance a sheet along the transport path with a non-uniform speed, and a discharge mechanism arranged at the transport path for taking over the sheet from the transport mechanism and discharging it into a tray, wherein the discharge mechanism is adapted to convey the sheet with a momentary speed that is different from that of the transport mechanism; and wherein a portion of the transport path between the transport mechanism and the discharge mechanism is curved along a buffer space to allow the sheet to bend within the buffer space and thereby to absorb the speed difference between the transport mechanism and the discharge mechanism.

Abstract: A discharge system for printed media sheets and a printer which utilizes such a discharge system, the discharge system including a tray for the media sheets; rotating transport elements forming a discharge nip for discharging the sheets onto the tray; a guide plate having a surface for guiding the sheets to the discharge nip; and a rotating wheel containing bristles for guiding the sheets towards the discharge nip; the wheel facing said surface of the guide plate. At least one driven transport belt forms one of the transport elements defining the discharge nip, and the guide plate passes in approximately a one-half turn around two pulleys around which the transport belt is passed.

Abstract: A printer including a printhead which is displaceable at the level of a print surface in a main scanning direction and in a sub-scanning direction with respect to a substrate situated in the print surface, and a supply unit for storing the substrate which is disposed on a core and delivering the substrate for transport to the print surface, said supply unit including support means for supporting the core at its end portions so that the core, while being supported, can rotate with the unwinding of substrate from the core, said support means containing an element for exerting a force on the core in the axial direction during the rotation thereof, whereby the core is pressed against a stop which occupies a substantially fixed position in the axial direction with respect to the print surface.

Abstract: A device for conveying and positioning sheets, comprising positioning apparatus for positioning one of the longitudinal sides of the sheets on the ideal transport line for said longitudinal side, the positioning apparatus being adapted to occupy an operative or an inoperative position, and actuating apparatus for moving the positioning apparatus, the positioning apparatus comprising a first conveying device and a second conveying device, each comprising two conveying members, at least one of which is formed by a roller, which two conveying members can form a transport nip extending parallel to the ideal transport line, the transport nip of the first conveying device extending along the ideal transport line and the second conveying device being situated at some distance from the first conveying device in the zone of the sheet conveying path, and drive apparatus are provided by which the roller (or rollers) of each conveying device can be so driven that each conveying device in its operative position exerts on

Abstract: A regulating device for copying machines used in forming an image of an original on an image carrier and transferring the formed image onto a receiving material in which the relative position of image and receiving material with respect to each other before the iamge transfer can be adjusted. The copying device is provided with a margining means which in response to said adjustment is automatically adjusted for rendering image-free all the zones of the image carrier in which image and receiving material do not coincide during the image transfer, so as to prevent contamination with image-forming material and the occurrence of undesired deposition of image-forming material on the image receiving material.

Abstract: A top panel of a copying machine is provided with a tray or like means forming a cavity recessed from bordering top surface areas for collecting staples removed from stapled bundles of originals to be copied, and a rigid finger protrudes freely into the cavity for removing the staple from a bundle of originals suitably placed onto and moved over the appliance. The finger has its top surface largely formed flat and tapered to an upturned narrowed tip that projects slightly above the plane of the adjacent top surface areas. By placing a stapled bundle of sheets on the appliance with the staple located ahead of the finger and the bent-over legs of the staple facing upward and then manually moving the bundle over the finger, the tip of the finger can engage between the staple and the sheets, and upon further movement of the bundle the tapered forward portion of the finger pulls the staple out of the sheets.

Abstract: A holder for electrographic developing powder comprises an oblong outlet opening for the powder and has the opening covered by a membrane and by a slide valve which is movable along channels bordering the opening and is provided near one of its ends with a cutting device that cuts the membrane as the slide valve is moved from a first position closing off the opening to a second position not covering the opening. The holder comprises a flexible end portion that can be contracted by being pinched in a direction substantially parallel to the plane of the slide valve, and from which projections extend laterally for engagement with notches in guides that support the holder over a powder reservoir. The cutting device is moved toward the flexible end portion as the slide valve is moved from the first to the second position.

Abstract: Device for the assorted collection of sheets, comprising a transport track and bins situated along this track. The bins are provided with guide organs and each bin can be moved so that its guide organ protrudes into the track so as to guide a sheet into a bin. In the transport track the sheets are transported by means of belts running around a vacuum holddown device so as to hold the sheets onto the belts.
