Abstract: In an apparatus for feeding an original document, the time which is needed until the first original document is transported onto a transportation path after storing original documents is shortened. The original documents stacked on an original document supporting plate are successively supplied one by one in order from an uppermost original document. A discharged original document is steadily and easily inserted between the original document supporting plate and the original documents stacked on the original document supporting plate. When a hopper sensor detects that the original documents are stacked on the original document supporting plate, the original document supporting plate is moved upward until the upper surface of the uppermost one of the original documents contact a level sensor. At this stage, the original documents are supplied successively one by one from the uppermost original document by a paper feeding mechanism.

Abstract: This invention relates to a sheet feeding apparatus having sheet carrying device unit for carrying sheets suspended by suspending unit, which is taken up by winding unit and thereby moves the sheet carrying device up and down to render the sheets fed from the topmost side of the sheets. Connection positions between the suspending unit and the sheet carrying device are located, in a direction perpendicular to a feeding direction of the sheets, at positions on a side of the sheet reference which is one end in the direction perpendicular to the feeding direction of the sheets, closer to the center of the sheets with respect to a position of a suspending original point of the suspending unit located over the sheet carrying device.

Abstract: An apparatus for sheet feed-out control is provided on an automatic sheet feeder used in conjunction with scanners, fax machines, printers, copiers, and the like. The apparatus comprises a feed-in roller set for feeding the sheet into a scanning position where a scanning process is performed and a feed-out roller set for pulling the sheet away from the scanning position and delivering the sheet onto a receiving tray. A pivotal pressing member is pivotally affixed proximate to the feed-out rollers. The pivotal pressing member is pivotally turned by the sheet as the sheet is being fed out of the feed-out rollers. As the sheet is entirely fed out of the feed-out roller set, the pivotal pressing member presses down against the tail edge of the sheet, thus flipping the sheet off the feed-out roller set. Since the sheet can be placed flat on the receiving tray right after it is entirely fed out of the feed-out roller set, a stack of sheets after being scanned can be piled up neatly on the receiving tray.

Abstract: A mail separating device has a conveyor channel, an input of which is connected to a sorting device for successively supplying the channel with flat mail items. The separating device includes a sensor which is located along the channel for generating a double-withdrawal signal on detecting a pair of at least partly superimposed mail items. The double-withdrawal signal activates a stop device, which is located along the channel and moves an appendix from an idle position to an activating position. A stop portion of the appendix contacts the vertical end edge of a first item in the pair. The impact of the stop portion on the vertical end edge arrests the first item while the second item in the pair continues traveling along the channel and is detached from the first item.
