At least one paper is fed from a paper entrance toward a paper exit by the paper feeding device, and the paper feeding device includes a first feeding path, a second feeding path, a pickup roller component and a suction element. The first feeding path intersects with a first end of the second feeding path so as to form a first intersection. The pickup roller component is disposed on the first feeding path to feed the paper located at the paper entrance into the first feeding path. The suction element is disposed above the first intersection and provides a suction. When the paper passes through the pickup roller component and is located between the pickup roller component and the suction element, the suction element guides the paper closest to the suction element onto the first feeding path.

摘要： Disclosed is an apparatus for feeding sheets of printing paper individually, which includes: a paper tray; a rubber pad installed in the proximity to the front end of a paper stack on the paper tray; a separating/transferring roller having a nozzle part on its outer periphery, for separately feeding a paper sheet using absorption force, wherein the separating/transferring roller is so spaced that its upper surface does not have an effect on the back of the lowermost paper sheet on the paper tray and the separating/transferring roller has such diameter that its lower surface faces the upper window of the scanning unit. With such construction, reliability of a paper separation and pickup can be increased with use of only one single separating/transferring roller. Manufacturing costs can be reduced, noise due to gear connection can be reduced, and installation space can also be reduced. Thus, a scanner having a more compact design can be manufactured.

摘要： An apparatus for sequentially feeding cards from the bottom of a vertical stack, which includes a card transport drum positioned below the stack so as to support the forward edge portion of the bottom of the stack. The drum includes a set of suction openings disposed transversely across the outer peripheral surface of the drum, and the openings are of oval outline. To sequentially feed the cards, the drum is rotated so that the openings move across the bottom of the lowermost card and the suction grips and holds the lowermost card on the surface of the drum, to thereby advance the lowermost card from the stack. The oval outline of the openings helps ensure that only the lowermost card is gripped and advanced by the suction openings. The apparatus also includes a vertically adjustable gate assembly mounted to overlie the forward edge of the stack and so as to define an outlet gate with respect to the drum, and a pair of rollers is mounted to the gate assembly which serves to reduce the weight of the stack at the gate.

摘要： The device for removing flat articles from a stack comprises at least one roller which contacts the uppermost article of a stack and is rotatable about a shaft and whose circumferential surface is covered by a layer consisting of a resilient material. The resilient layer positioned on the circumferential surface of the roller includes a number of suction cups. The roller is designed as a hollow roller which includes a mechanical device by which the suction cups in the resilient layer on the circumferential surface of the roller can be operated by partial deformation of said resilient layer. The suction cups are formed by depressions in the resilient layer on the circumferential surface of the roller, said depressions cooperating with one bore each in the wall of the roller.
