Abstract: An envelope hopper having a plurality of bottom rods to form a supporting surface for supporting a stack of envelopes and a paddle to push the envelopes towards an envelope feeder at the downstream end. A scrub wheel is rotatably mounted on a fixed, rotation axis on the paddle and is in contact with one of the bottom rods. The rotation axis of the scrub wheel is oriented at an angle relative to the rotation axis of the contacting rod, so that when the contacting rod rotates, it causes the scrub wheel to rotate, thereby producing a force on the paddle urging the paddle to move towards the downstream end. Preferably, the envelope hopper has a side rod on one side of the envelope stack, and the supporting surface is tilted from the horizontal surface, so that the envelopes are moved towards the side rod by gravity in order to register against the side rod. Preferably, the side rod also rotates in order to reduce the friction between the envelope stack and the side rod.

The machine then selectively recovers such documents from storage and dispenses them to other users. The machine includes a central transport (70) wherein documents deposited in a stack are unstacked, oriented and identified. Such documents are then routed to storage areas in recycling canisters (92, 94, 96, 98). When a user subsequently requests a dispense, documents stored in the storage areas are selectively picked therefrom and delivered to the user through an input/output area (50) of the machine.

Abstract: A sheet feeding apparatus has a pair of feeding roller and separating roller an inter-shaft distance changing mechanism for the pair of rollers, and sheet detecting means, and a sheet fed is rammed against the surface on which the feeding roller and the separating roller overlap each other to thereby correct skew feeding, and the feeding roller and the separating roller are moved away from each other to thereby feed the sheet. When the passage of the fed sheet between the feeding roller and the separating roller is detected the feeding roller and the separating roller assume a state in which sheet feeding is impossible. By the above-described operation being performed for each sheet, the correction of skew feeding and the separation of a sheet are effected by the feeding roller and the separating roller.

Abstract: A sheet supply system includes a sheet support table which is movable up and down and on which a stack of a plurality of sheets are supported, a sheet feed-out roller which feeds out the sheets on the sheet support table one by one from the uppermost one, and a table drive mechanism which moves the sheet support table up and down relative to the sheet feed-out roller. A level sensor detects the level of the uppermost sheet on the sheet support table, and a sheet feed-out level at which the uppermost sheet is kept during sheet supply operation of the system is set by use of an entry key. A controller actuates the table drive mechanism to move upward the sheet support table when the level of the uppermost sheet on the sheet support table as detected by the level sensor lowers by a predetermined value from the sheet feed-out level and stops the table drive mechanism when the level of the uppermost sheet on the sheet support table as detected by the level sensor reaches the sheet feed-out level.

Abstract: A sheet feeder feeds sheets separated from a stack to a feed head which is translatable toward take away nip rolls. The sheets are separated from the stack by fluffers and acquired by an acquisition surface of the feed head which is in communication with a vacuum pressure. An air knife is used, in conjunction with a corrugation surface, to separate any secondarily acquired sheets from the acquisition surface. The time for acquiring the sheet is determined from the opening of a vacuum valve in communication with the feed head to the acquiring of the sheet by the acquisition surface. A controller adjusts the position of a supporting tray that supports the stack to maintain the sheet acquisition time as short as possible.

The paper sheet feed mechanism comprises a feed roller conveying paper money to the right direction of the drawing, a spring pressing the feed roller against the paper money, a sensor detecting the press force that the paper money receives by being pressed by the feed roller, a push-up board pushing up the paper money, and a control section regulating the height of the push-up board based on the detection result by the sensor, and also comprises a pick roller conveying the paper sheet at a conveyance speed faster than a conveyance speed by the feed roller.

Abstract: The present invention provides a paper feeding apparatus for use in an image reader, e.g. such as an image scanner, which is designed especially to prevent overlap feeding of sheets of paper, and can adjust both the pressing forces between a hopper for carrying sheets of paper in a stacked manner and a pickup roller for paper feeding and between a parting roller and a retard roller for the prevention of overlap feeding. The paper feeding apparatus of the present invention serves to feed the sheets of paper one by one from the hopper and to restrict overlap feeding by the parting roller and the retard roller. This optimizes the paper feeding in the pass line from the hopper to the preventing mechanism for overlap feeding, thereby achieving a secure prevention overlap feeding.

Abstract: A sheet feeding device that may be constructed using a first tray mounted in a frame and biased by an elastic member to bring the paper stacked on the first tray into engagement with a pickup roller. A finger is pivotally attached to the frame to force the paper loaded from the first tray to be loaded sequentially. A second tray is attached to the frame and has an end that forms a document guide that is interposed between the finger and the pickup roller. Alternatively, the second tray can end before the pickup roller and a film can be attached to the second tray to form a document guide that extends between the pickup roller and the finger. Regardless of the method used to form a document guide, the document guide allows a user to intersperse a manually fed document between documents that are being loaded from a separate tray using an automatic document loading process.
