ABSTRACT:
A microfiche editing device for copying images contained in several microfiche frames on a first microfiche simultaneously onto a second at least partly unexposed microfiche; the device includes an array of illuminating means which can be selectively brought into use each to project light through a selected frame on the first microfiche so as to expose frames of the second microfiche placed in contact with the first microfiche; the illuminating means may include either a hinged mirror arrangement or a fibre optic arrangement which feed light into a collimating array of cells each of which correspond to a microfiche frame of the first microfiche. The second microfiche can be formed either by placing the emulsion the same way up as that of the first microfiche or alternatively by placing the emulsion of the second microfiche face to face with the emulsion on the first microfiche; in the latter case a reverse image is produced which can be used to generate further obverse images or which can be used with a further obverse microfiche to produce a composite microfiche formed of an obverse and reverse microfiche held together so that images on one microfiche may be seen through blank frames in the other microfiche.
