<p>OPTICAL SYSTEM FOR ROTARY CAMERA A flow, or rotary type, microfilm recording apparatus for filming documents having a document transport means to move documents past an aperture area. A combining mirror, camera mirror, side mirror and camera lens are all mounted in a common plane. The plane of the mirrors is essentially perpendicular to the plane of the document as it passes through the filming aperture area. Either or both sides of the document can be filmed simultaneously. The possibility of having multiple reflected images on the film is eliminated by tilting one of the mirrors.</p> |
