Abstract
A microfilm recording machine of the type which makes a photographic reproduction of each document processed therethrough has an improved document transport system for presenting the documents in a predetermined focal plane within the machine document scanning zone. The transport system includes a single glass plate having a longitudinal major surface within the predetermined focal plane and a transverse axis forward of the major surface. A pair of cooperating transport rollers on each side of the glass plate form nips for engaging the documents. The nips are forward of the glass plate major surface and the rollers are rotatable about axes to transport each document through the scanning zone. The plane embracing the axes of rotation of each respective roller pair converges upon the transverse axis so that each document is directed toward and against the major surface as it is transported through the scanning zone. A fan for providing a column of air flow aimed at the major surface holds each document flat against the glass plate major surface.
