ABSTRACT:
Microfilm apparatus suited to use in a small establishment and employing standard microfilm in roll form. Successive microfilm units each comprising an image-carrier portion constituted by a set number of frames which have been exposed in an exposure compartment in the upper portion of the apparatus to image-wise light reflected from documents to be microfilmed and a tab portion for carrying an identification code indicative of the content of documents recorded on the image-carrier portion are detached from the remainder of the film and immediately processed in a development processing compartment in the lower portion of the apparatus, remaining film being available for production of subsequent microfilm units, and processed microfilm units being moved to the exterior of the apparatus. The apparatus also includes blower means which blows air from the exposure compartment and into and through the development processing compartment, and to the exterior of the apparatus, whereby the exposure compartment is sealed against corrosive vapors produced in the development processing compartment.
