DUAL ROLL ROTARY MICROFILMER FOR 25X REDUCTION OR LESS

A 16 mm rotary microfilmer that operates in 25.times. duplex mode that simultaneously photographs both sides of a document. Each side of the document is imaged onto a separate roll of film resulting in greater resolution and easier readability. The microfilmer gives the same numerical address to the images of each side of the document so that the images of the front and rear of the document are easily mated to each other and identified as a single document to reduce confusion in the retrieval process.
