Abstract
A high speed aperture card printer and method include a rotatable glass cylinder temporarily to transport aperture cards fed one directly after the other onto the cylinder. The aperture cards are tightly held against the cylinder by parallel endless belts positioned on either side of the microfilm carried by the aperture card so as to leave one surface of the microfilm uncovered. The printer includes an optics system passing light radially outwardly through the rotating glass cylinder and the microfilm transported thereby optically to scan images on the microfilm for printing copies thereof on plain paper.
