Abstract
An in-line passive "pinwheel" copy sheet rotator in a rotating disc configuration for use in a copier, intermediate module or the like rotates copy sheets 90 or 180 degrees as desired. The disc has four quadrants and is used in combination with and positioned in-line with a sheet transport such as a ball-on-belt registration mechanism and an edge guide for registering the sheets once they have been rotated. Copy sheets come into contact with fins on the disc due to their movement by the ball-on-roll transport and are rotated along with the disc. A deflector is positioned over a portion of the disc in order to enhance the guiding of copy sheets into the disc by reducing the inertia of the disc after each copy is rotated and indexes each quadrant through the application of drag on the fins.
