Abstract: A covered feed unit (1) fits on the housing of an office machine (7), in particular, of a flat-bed scanner, having a feed opening (47) for recording media (46), and having a discharge opening which is arranged in a plane located beneath the feed opening, and which is intended for the recording media. Between the feed opening and the discharge opening, the covered feed unit (1) has a deflecting device (6) which has a drive unit (33). The covered feed unit transports the recording media (46) via a transporting path by means of driven transporting rollers (35a, 35b) and idler rollers (38), which form a clamping nip with the transporting rollers. The deflecting device (6) is enclosed by a covering. An upper cover (3) which bounds the feed opening is connected pivotally via a hinge (32) to an upper cover (5) which bounds the discharge opening. The drive unit (33), with its drive-connected transporting rollers (35a, 35b), is disposed in that end region of the upper cover (3), adjacent to the hinge (32).

Abstract: A delivery device conveys the sheets which are output by a laser printer for delivery onto a pile. For adaptation to the growing height of the pile, at least one conveying roll defining an output is arranged on a height-adjustable carriage. A sensor lever scans the respective height of the pile and brings about automatic tracking of the carriage. The carriage is mounted so as to be longitudinally displaceable on a drive shaft by means of at least one guide. The carriage can be moved vertically along the drive shaft by driving wheels which press against the drive shaft. By means of this device, the achievable stacking height can be multiplied relative to the standard height.

Abstract: A description is given of a scanner (2) which is intended for manual document input and can be converted for automatic document intake, having a cover unit (30) which comprises a cover (38), a folding part (36) and a retaining part (34) which is connected releasably to the scanner housing (4). The folding part connects the cover to the retaining part in a link-like manner via parallel hinges (40) fitted on both sides of the folding part. The folding part, furthermore, exhibits an elongate through-passage (44) which extends over the operating width and runs parallel to the hinges.

Abstract: The device (11) conveys the sheets (14) output from a laser printer (10) for deposition on a stack (12). For matching to the growing height of the stack (12), at least one conveying roller (28) defining an outlet (37) is arranged on a height-adjustable carriage (21). A feeler lever (26) senses the respective height of the stack (12) and effects an automatic tracking of the carriage (21). By means of the device (11), the achievable stack height can be multiplied with respect to the standard height.

Abstract: A feeding device 2 is arranged upstream of a distributing device 20 and comprises a sheet duct, and a pair of clamping rollers 10, 12 arranged at the outlet end 8 of the latter. The distributing device comprises an individual path 80" for each of a multiplicity of delivery points 70". Each path is delimited by flexible bands 56. On the side directed against the feeding device each of the bands is connected to a compartment-forming member 58 of a receiving compartment 82 and on the opposite side to a deflecting member 84. The receiving compartments form a unit 22, which may be swivelled relative to the feeding device. Transport rolls 64, which are disposed along the bands, are common to all pathes and are movable transversely to the path direction.

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: A sorting apparatus for sheets which are supplied from an office machine such as a printer, comprises a take-up site for receiving the sheet from the printer and a plurality of output sites. The sheet can be deposited into any one of the output sites. A support carries pairs of engaged rollers which define a feed channel for a sheet. The feed channel has an inlet end which is alignable with the take-up site for receiving a sheet from the office machine. The support can be pivoted about a swiveling axis to bring the outlet end of the channel to any one of the output sites. A control mechanism is connected to a stepper motor which engages the support for rotating the support about its swiveling axis.

Abstract: An apparatus for conveying sheet-like recording carriers, such as paper, cards or envelopes without adjusting for their relative thicknesses is disclosed. In the conveying path of a sheet from a supply stack to a driven platen, a baffle plate and a deflecting surface are disposed as a separating device. The deflecting surface causes a pressure on the edge of the baffle plate to be exerted against the conveyed sheet due to the deflection by the deflecting surface. As a result, a sheet moving along beneath the conveyed sheet will abut with its forward edge against the surface of the baffle plate and is detained until the previously conveyed sheet vacates the baffle plate.

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).
