    Abstract: The invention relates to a printing or copying device having a photoconductor drum (10) for receiving two adjacently arranged toner images for a recto and a verso of a recording medium (15). Provided for the simultaneous transfer of the toner images onto the recording medium (15) are two separate transfer ribbons for the recto toner image and the verso toner image. In this case, one transfer ribbon is deflected over a deflection device in such a way that the transfer ribbons (T1 and T2) are positioned one above the other in a fuser station (19) designed as a thermal printing fuser station. The recording medium (15) is passed between the transfer ribbons (T1 and T2) and is thus printed verso/recto simultaneously.

    Abstract: In a dispensing device for sheet material that includes a draw-off device and a single feed device with at least one draw-off roll, several conveyor rolls (22) arranged side by side with some axial spacing and with mating rolls (24) that are axially offset and are radially adjustable with respect to the conveyor rolls (22), where the mating rolls (24) and at least one of the conveyor rolls (22) that can be driven in the same direction with the former are made of a hard material, a ring-shaped strip (44) made of an elastic deformable material is embedded in the peripheral surface of the conveyor roll (22) that is made of a hard material where the axial width of this ring is smaller than the axial width of the peripheral surface of the conveyor roll (22) and projects radially above the peripheral surface in the unloaded state.

    Abstract: A dispenser for sheet material, especially notes, consists of a storage container (14) for a stack of sheets (12), an extraction and separation device allocated to the storage container (14) with at least two extractor rollers (18) at an axial distance apart intended to bear on the sheet (22) to be extracted from the stack of sheets (22) and a swinging shaft (42) parallel to the plane of the sheets and bearing the extractor rollers (18). Said shaft consists of a tubular body, the central section of which is borne with radial clearance via a universal joint (48) on a drive shaft (20) transfixing it longitudinally and rotatably joined with it, whereby the drive shaft (20) is fitted in bearings fixed in position in relation to the storage container (14). The hollow body is adjustably guided between tines (70) of a guide fork (72) directed perpendicularly to the plane of the sheet.
