Abstract: A staging hopper for supplying packaging blanks includes a first conveyor positioned downstream of a second conveyor. The first conveyor supports and periodically transfers packaging blanks in a primary group of blanks to a blank delivery position. A second conveyor supports and intermittently transfers packaging blanks in a secondary group of blanks onto the first conveyor. The top edges of the secondary group of blanks rest at an angle against the primary group of blanks to define a longitudinal gap between the lower edges of the blanks in the primary and secondary groups. Photosensors are provided to detect the presence and absence of packaging blanks within the longitudinal gap. In addition to advancing the primary group of blanks, the first conveyor advances the forward blanks in the secondary group across the gap toward the primary group. The photosensors detect the presence of these blanks as their lower edges move across the gap.

Abstract: An apparatus for feeding individual sheets from the bottom of a sheet stack. The sheet stack is placed in the paper tray with the lead edge abutting the sheet feeding apparatus. The face of the stack rests against the main fang. As the feed roll forwards the sheets from the bottom of the stack to a position under the main fang, further sheet separation occurs as the lead edges of the sheets strike a substantially arcuate member located between the main fang and the retard roll. The curved portion of the member which has a larger radius of curvature than the retard member causes the sheets to be shingled out permitting a single sheet to pass under the retard roll and to be advanced by the feed roll.

Abstract: A recirculation-type document feeding device for a copying machine having a function of allowing a copied document to be alternatively discharged to a discharge tray or returned to a document tray. In a case of copying several times, the documents stacked on the document tray are transferred one by one to a document setting portion on a platen to be copied, and then, sent back to the document tray through a return passage. After copying completely, the copied documents may be eliminated to the discharge tray.

Abstract: A conventional pocket for delivering signatures in a bindery line is modified by providing a lift plate which is hinged to the leading edge of the pocket's signature support tray. A suitable actuator under control of the system's computer is made to raise and lower that lift plate, depending upon the number of machine cycles which will be executed before that particular pocket will be called upon to deliver a signature to the magazine being assembled. If more than a predetermined number of machine cycles will take place before a signature must be delivered, the actuator lifts the lift plate and, in doing so, elevates the leading edge of the signature stack to the point where the lowermost signature is positioned out of contact with the hopper's separator disc. This prevents unwanted abrasion and marring of signatures.

Abstract: An articulated document feeder and diverter which allows pivoting and rotation about two mutually perpendicular axis of rotation to thereby allow idle rollers mounted on a pivotable carrier to maintain contact with drive rollers, whether a divert pivoting occurs or not. Compliance members, preferably resilient O-rings mounted on the periphery of the idle rollers, help to absorb unevenness in the contact face between an idle roller and a drive roller/s/.

Abstract: Sheet feed apparatus including a scuff feeder for reliably transporting sheets from the bottom of a stack of sheets without marking of the sheets.

The loading device includes a locating mechanism which allows the involved media to be precisely oriented on the workpiece support surface in registry with two orthogonally oriented coordinated axis. The system further permits loading and unloading of covered cassettes in daylight without exposing the media supply to light which might otherwise be cast onto it. The system further provides for the safety locking of stacked media within the photoplotter to prevent inadvertent removal.

Abstract: An improved feed arrangement is provided for use with currency handling apparatus in which cooperating action of an actively-driven drum roller is used for feeding bills stacked in an input bin along the bill transport path. The picker roller is rotationally driven, not by direct contact with the drum roller, but by contact with a pressure roller which is driven by the drum roll. In effect, the picker roller is rotated in a direction counter to the direction of the bill flow so that bills other than the bottom bill in a given stack are effectively pushed away from the direction of bill flow. The picker roller is, consequently, activated to function as a retard roller, as opposed to the conventional feeding action provided by picker rollers which are in counter-rotating contact with the drum roller about the direction of bill flow.

Abstract: A paper feeding device which extracts from a cassette accommodating a stack of sheets such sheets one at a time and feeds them to the next step, namely an image forming part, comprises an attracting member capable of being moved between an attracting position at which the attracting member attracts a sheet from within the cassette and a feeding position which lies above the attracting position, a pressing roller capable of being moved between a position of retraction and the feeding position, and a rotary roller capable of cooperating with the pressing roller in nipping the sheet at the feeding position. The pressing roller moves to the feeding position after the elapse of a prescribed time following the completion of the motion of the sheet by the attracting member to the feeding position. The rotary roller is rotatably set in place at the feeding position.

Abstract: In a cassette type sheet supplying device, two or more adjoining spaces for installing standard cassettes therein are joined into a continuous space to enable a large cassette to be installed in the space in lieu of two stantard cassettes. When no cassette is installed or a standard cassette is installed, a paper feeding unit is pulled to the paper feeding position by a spring, and a claw portion of a lock material engages lock holes formed on paper feeding unit side frames so that the paper feeding unit is held to the paper feeding position. When the large cassette is inserted in the cassette installation space, a lock release projection formed on the large cassette comes in contact with a projection of the lock material and extends it to the outside. At this time, the claw portion comes off from the lock hole. When the large cassette is further inserted, the paper feeding unit is pushed through a cushion material.

Abstract: In a system of transporting sheets in an output path of a copier or printer to a sheet stacking area with opposing first and second sheet feeding rollers forming a sheet transporting nip engaging the leading edge of a sheet, while producing a relative orbital motion of the opposing rollers to progressively pivot the nip and thereby change the angular direction of motion of the leading edge of the sheet, plural mode selectable operation of this pivotal motion is provided. There is a selection between faceup and facedown stacking of the sheets by one selectable orbital motion of the nip. This selected orbital motion pivots the nip by greater than 90 degrees with the sheet's leading edge held in the nip, so that subsequently, the leading edge of the sheet is moving in a direction substantially different from the direction of motion of the leading edge when the leading edge first entered the nip, and the sheet is inverted.
