Abstract: A single-sheet feeder for a copier or printer (16) comprises a plurality of magazines (10, 12, 14) which are installed beneath the printer (16) and which are each equipped to receive a stack of sheets (22, 24). The portion of each magazine which receives the stack can be pulled out for refilling, as a drawer. In addition, each magazine comprises a single-sheet feed mechanism (28, 34) and conveying rollers (46, 48). Sheets from a magazine (12, 14) below the uppermost magazine (10) are conveyed through the superimposed magazines (10, 12). The direction in which the drawers (72) are pulled out corresponds to the conveying direction during the feeding of successive single sheets from a magazine. By virtue of this feature, that side of the feeder at which the user operates and tends it coincides with that side of the printer (16) at which he or she performs the primary operating and control actions.

Abstract: An envelope (12) which is the lowest in a stack is grasped at the edge of its flap part (26) by a carrier tooth (24) arranged on a conveying belt (18) for separating it from a stacking magazine (10). The envelope is fed directly to an office machine in a feed direction (14). Due to the arrangement of the conveying belt (18) on the removal side (28) of the magazine (10), the separation and feed are effected in one step by the single conveying member.

Abstract: A sheet feeding apparatus for use with a printing office machine includes at least one magazine, a drive wheel for removing a single sheet from the magazine and passing the sheet in a forward direction the nip of a printing wheel; the printing wheel is drivingly connectable with the separating roller and is driven in a forward direction to provide rotary power to the sheet feeder wheel to effect feeding of a single sheet to the nip; the method includes first driving the printing wheel in the forward direction and then reversing the direction of rotation of the printing wheel to move the sheet back out of the nip, the reverse rotation being disengaged from the separating wheel by a latch device.

Abstract: The sheet-processing apparatus has a mechanically-rotated platen at its sheet-processing station, upstream, along the pair of powered transport rolls and upstream of them, at the outlet of the sheet magazine, a powered sheet-abstracting roll. A drive train powers the transport and sheet-abstracting rolls from the platen. A mechanical sensing finger is disposed in the nip of the transport rolls. As the finger is contacted by an end margin of a sheet, the roll-powering drive train is mechanically triggered to be uncoupled. Upon a uniform degree of subsequent rotation of the platen, a return mechanism recouples the drive train and re-cocks the trigger.

Abstract: A transport or conveyor belt provided with prongs and extending around two rollers serves to convey a recording medium to and away from a platen or the like. To facilitate insertion of the starting portion of the recording medium which, for example, may be constituted by continuous forms or form sets the transport belt including the carrier therefor can be pivoted into such a position that the recording medium can be placed with its marginal perforations on the prongs of a threading or insertion roller and into an open guide gap.

Abstract: Only the topmost sheet (12) of a stack is fed from a supply box (10) by transportation rolls (16) by way of a separating arrangement (18) to a pair of transportation rolls (20, 22). This pair transports the sheet further until the ray of a light (66) is interrupted and as a result the coupling (26) is uncoupled. As soon as the platen (32) driven by a line stepped motor (30) assumes a starting position, the coupling (26) is again engaged. The peripheral speeds of the rolls (20, 22) and of the platen (32) corresponds to one another so that the platen (32) together with a contact pressure roll may accept the sheet. After lettering, the sheet is transported by the pair of rolls (34, 36) into a file box. The pair of transportation rolls (20, 22) as well as the transportation rolls (16) are driven via a belt (50, 54) by platen drive (30).

Abstract: A sheet transporting magazine for automatic typewriters or the like with a three point bar structure for arching a stack of sheets in the conveyance direction while disposed in the magazine to prevent the sheets from canting laterally in the magazine.

Abstract: Transport device for transporting a foil-like data recording strip of material having perforations along its borders for receiving pins disposed in endless transport belts entained about sprocket wheels. The belt pins have respective recesses which are engaged by the sprockets of at least a driving sprocket wheel in a form-fitting manner with the engagement being at a level which is at least at if not beyond the outer surface of the transport belt.
