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.

Abstract: A mounting for a glass plate which is adapted to be disposed in the scanning zone of a microfilm recording machine of a type which is particularly designed for processing documents, such as, for example, bank checks, and which comprises a transport system including spaced pairs of infeed and outfeed rollers with light, mirror and camera arrangements for photographing the documents onto a microfilm while they pass through the scanning zone formed by the gap between the pairs of feed rollers, the plate being positioned so as to provide a document supporting surface which insures that each document is presented to the scanning zone within a focal plane of the camera so as to achieve high resolution and the mounting being in the form of a guide block or plate mounted at one side or end of the scanning zone with a guideway formation in which the plate is adapted to be moved and with a slot arrangement and a latch spring adapted to cooperate with a pin on the plate assembly for turning the plate and locking it in t
