ABSTRACT:
A simplified microfiche recording apparatus and method is provided that images a light image reflected through a fixed mirror train from hard copy or other source in microimage size on an intermediate dry-process film, develops the microimage and transfers the microimage by contact printing to an archival microfiche film. Stations are provided for imaging, developing and transferring which are in fixed relation to each other along a stationary intermediate film head. Single frame advancement of the intermediate film is utilized from station to station, where suitable, to avoid fogging of the intermediate film by insuring that the portion of the intermediate film which is subject to light piping from the transferring station contains developed microimage. A read station is provided to allow reading and/or annotating microimages recorded on the microfiche film utilizing a read lens, the optical axis of which is shifted to allow an image to be projected from the microimage film through the read lens and the same mirror train utilized for intermediate film exposure. The read station is in fixed relation to the intermediate film head and imaging developing and transferring stations.
