Microfilm duplicating apparatus

摘要

A microfilm duplicating apparatus for duplicating images, recorded on a master film onto a photographic duplicate film, comprising a light source for illuminating any one of the images on the master film from rear, a single reflective mirror for reflecting a luminous flux, which has been emitted from the light source and passed through the master film while carrying the image to be duplicated, so as to travel towards the duplicate film, and an image forming lens assembly consisting of two facing lenses of equal focal length disposed on the path of travel of the luminous flux.
