摘要： A paper feeder for transporting paper sheets, includes: a head fan that blows air on the paper sheets; a suction fan that applies negative pressure to the paper sheets blown by the head fan; a switching member that changes the direction of the air from the head fan; a head shutter that blocks the flow of the air directed by the switching member; and a hardware processor that determines the blocking time of the airflow, wherein the switching member changes the air direction between a first direction for floating the paper sheets and a second direction toward the suction fan, and the hardware processor determines stop timing of the air blow in the second direction directed by the switching member as the start timing of clocking the blocking time of the airflow, based on the weight and the resistance to an external force of the paper sheets.

摘要： A sheet feeding device includes: a sheet stacking member; an air blowing unit configured to blow air onto the sheet bundle placed on the sheet stacking member to suspend multiple sheets of the sheet bundle; a lifting/lowering unit configured to lift/lower the sheet stacking member; an optical reflection sensor configured to detect a suspended sheet suspended by the air blowing unit; and a control unit configured to control the lifting/lowering unit based on an output value of the optical reflection sensor. The optical reflection sensor is configured to be capable of detecting an area corresponding to multiple sheets in a sheet suspension zone extending between a non-suspended sheet bundle and a conveying member configured to convey an uppermost sheet of the multiple suspended sheets. The non-suspended sheet bundle is made up of sheets not suspended during a period when air is blown by the air blowing unit.

摘要： A media-guiding system includes a media-guiding roller having a roller axis and an exterior surface having one or more grooves formed around the exterior surface. A media travels along a transport path past the media-guiding roller with a first side of the media facing the exterior surface of the web-guiding roller. An air source provides an air flow into one or more of the grooves, the air flow being directed between the first side of the media and the exterior surface of the media-guiding roller thereby producing a Bernoulli force to draw the media toward the exterior surface of the media-guiding roller and providing an increased traction between the media and the media-guiding roller.
