Abstract
A sheet aligning arrangement adapted to accommodate a plurality of sheets fed into it for aligning, and to feed out the aligned sheets one sheet by one sheet. The arrangement includes a feed roller, a first aligning member movable between a first position defining a sheet aligning reference position and a second position parallel to the first position and defining a sheet transport reference position, a second aligning member located in a position confronting the first aligning member, and pivotable in a direction intersecting at right angles with a sheet transport direction, and a displacing device for displacing the first aligning member to the first position during the alignment to effect aligning together with the second aligning member, and also for displacing the first aligning member to the second position during the re-feeding of the sheets by the feed roller, while pivoting the second aligning member to align the sheets.
