Abstract
Sheet transport apparatus has a pair of driven transport rolls and a pair of associated idler nip rolls forming sheet transport nips therebetween and defining a sheet transport path, one of the pair of transport rolls and pair of idler rolls being fixedly supported in a sheet feed table, the other of the pair of transport rolls and pair of idler rolls being mounted on a shaft which is pivotally mounted about an axis perpendicular to the shaft and parallel to the sheet feeding path, the shaft being pivotally mounted at the midpoint between the pair of rolls in a pivot housing extending across the sheet feeding path, one end of the pivot housing fixedly engaging the sheet feed table and including a spring to bias the other end of the pivot housing toward the sheet feed table to enable the shaft to pivot about the axis to provide the same nip force between each of the driven transport roll and its associated idler nip roll.
