The invention relates to an input/output device for unexposed or latently exposed photographic sheet material for use in combination with photographic material evaluation devices. The invention comprises a flat light-tight cartridge having an opening, a film support displaceably arranged within said cartridge and externally operable, and a light-stop for said opening. The cartridge is insertable into a socket of the evaluation device so that the film can be shifted out of the cartridge and into the likewise light-tight evaluation device to be secured to holding means of a recording drum in said device. By sucking means within and respective rotation of said drum the film is evenly attached to the drum surface. By control of the input/output operation by means of a control unit an automatic handling of film material at normal light conditions is feasible.
