Abstract: Apparatus for the production of duplicate micro and other film from an original film in which the duplicate film of considerably greater length than the original film is housed on a spool in a light tight magazine and fed therefrom through a light trapped slot, the duplicate film and the original film being fed together over a transparent cylinder in a lamp house, an opaque slotted cylindrical sleeve surrounded by the cylinder and a lamp within the sleeve. The films are held in contact with the cylinder by an endless belt driven synchronously with the take up spools for the films, a sensing finger being mounted to engage the original film as it is taken up by the delivery spool to stop the apparatus a predetermined interval after the last image on the film. The duplicate film in the magazine operates a meter to register the length of film remaining on the spool in the magazine.
