ABSTRACT:
A desk-top camera/processor-reader apparatus for electrophotographic film includes a primary optical system of three fixed mirrors (24, 26, 28), and a pivotable mirror assembly (36) for defining optical paths between a copyboard station (12) and the microfilm (30) as well as between the microfilm (30) and a rear-projection screen (18). The pivotable mirror assembly (36) is movable between two extreme positions, the first position (36') being the camera/photographing mode, and the second position (36") being the reader/viewing mode. Camera/photographing and reader-projection lamps (42, 56) are provided for alternative energization and illumination of the copyboard station original documents and the microfilm (30). During the camera/photographing mode, the original document at the copyboard station (12) is illuminated by the photographic lamp (42) and the illuminated image is transmitted to the microfilm (30) for recording thereon by means of the three fixed mirrors (24, 26, 28), the movable mirror assembly (36) having been removed from the optical path defined between the copyboard station (12) and the film (30). During the projection mode, the film (30) is illuminated by the projection lamp (56) and the image is transmitted to the screen (18) by the three fixed mirrors (24, 26, 28) and the movable mirror (36) which has been removed into the optical path defined between the mirrors (24, 26, 28) and the copyboard station (12) so as to intercept the projected image and transmit the same to the screen (18).
