Abstract

A sheet stacking apparatus for stacking a side variety of sheets including flimsy sheets has a rotatable disc that receives each sheet in a slot thereof and inverting the sheets. A transport belt is closely adjacent one surface area of the disc and has a portion thereof positioned at an acute angle with respect to a line tangent to the one surface of the disc so that the trail edge of all sheets being inverted by the disc contact the belt and are inverted.
