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 the proper position while enabling ready manual removal and replacement.
