Abstract
A microfilm system stores document on film for compact and secure filing. Full-size paper copies may be made of any document in the file. A single, attractively styled, compact housing contains a preferably manually fed camera, with an electrophotographic 16 mm roll film packaged in a cassette for easy film loading and unloading. The film is processed immediately after each image is recorded so that it is ready for instant retrieval. A bar code is recorded adjacent each image, responsive to a keyboard operation. During retrieval, a high-speed film transport searches for a designated bar code. Once an image is found, it may be projected on either a screen or paper in a printing system.
