Abstract
A sheet alignment device is provided with a movable aligning member and a variable push member, movable to push one or more sheets fed onto a tray toward a sheet aligning reference surface defined on the tray, thus to align the sheets. The sheets of large size are pushed at the point close to the center of gravity of the sheets toward the aligning reference surface mainly by the variable push member, and the sheets of small size are pushed at the point close to the center of gravity of the sheets toward the aligning reference surface mainly by the movable aligning member. The sheets of any size can be properly pushed stably without experiencing an undesirable rotational moment, thus to be exactly aligned.
