摘要： A sheet feeding apparatus includes: a front edge air part that blows front edge air, along a conveying direction of a sheet stacked, to a front edge side of the sheet; side edge air parts that are provided to face each other along an orthogonal direction to the conveying direction of the sheet and blow side edge air, along the orthogonal direction, to respective side edge sides of the sheet; a suction part that suctions, by a negative pressure, the sheet to which the front edge air and the side edge air are blown; and a conveyer that suctions and conveys the sheet suctioned by the suction part, wherein the front edge air and the side edge air are blown to the sheet to float the sheet in a posture in which a portion protruding from the conveyer of the sheet is lower than a conveying surface of the conveyer.

摘要： An apparatus in which a stack of sheets is detected at a preselected location. An air jet is directed towards an edge of the stack of sheets at a preselected location. A pressure transducer is located at the prescribed location and positioned to have the air jet at impact thereon. The pressure transducer is enabled to transmit a signal indicative of the absence of the stack of sheets at the preselected location in response to the air jet impacting thereon. The pressure transducer is inhibited from transmitting the signal in response to the stack of sheets blocking the air jet. When the stack of sheets blocks the air jet, the signal from the pressure transducer indicates the presence of the stack of sheets at the preselected location. A pneumatic stack height detector of this type may be used to regulate the movement of a stack of sheets used in electrophotographic printing machines.

摘要： A method for use in a sheet feeder having a sheet stacking unit with a bottom plate to support a sheet bundle in which air is blown against a side edge of the sheet bundle near the topmost sheets of the bundle, thereby lifting these sheets from the bundle, and separating the uppermost sheet from the bundle, and conveying this sheet away from the bundle, wherein the lifting of the sheets when the bundle is nearly depleted is assisted by forcing an element situated underneath the bundle to push against the bundle solely when air is blown against the side edge of the bundle. A sheet feeder suitable for applying the present method and an imaging apparatus for incorporating the sheet feeder is also provided.

摘要： An image forming apparatus with a foreign material removal apparatus is formed of a sheet feeding table which is vertically movable and supports printing sheets thereon; a sheet feeding device for feeding the printing sheets stacked on-the sheet feeding table one by one; an image forming device for forming an image on the printing sheet fed by the sheet feeding means; a detecting device situated adjacent to the sheet feeding means and detecting the printing sheets fed by the sheet feeding device; and a foreign material removal device for removing foreign material covering the detecting device. The foreign material removal device includes a pump attached to the sheet feeding device and driven by vertical movements of the sheet feeding table to flow air, and a nozzle situated adjacent to the detecting device and attached to the pump. When the sheet feeding table moves vertically, the pump allows air to flow through the nozzle to remove the foreign material covering the detecting means.
