The device for duplicating microfilms or microfiches comprises an exposure section (4), a separating means (8) in which the two components (2,3) of the film material, viz. film original (2) and copying film (3) are mutually separated in the film plane during the further advance by a marginal guide means or keep-off plate (23) so that the copying film (3) immediately gets into the developing section (9) while the film original (2) is discharged laterally. The separating means (8) consists of an inclined roller assembly of two groups of transport rollers (12a, 12b, 12c; 13a, 13b) provided at both sides of the film material (2,3) and of which one group of at least two transport rollers (13a, 13b) is arranged in such a way that their roller axes (16a, 16b) extend obliquely relative to the opposite three lower transport rollers (12a, 12b, 12c). The transport roller groups mounted on both sides of the film material are staggered while their mutual distance is as close as to permit a comb-like meshing of the roller peripheries thus causing the film material (2,3) to wavily pass therethrough.
A device for duplicating microfilms, microfiches or the like comprising a developing section downstream of an exposure section, means for moving an original film and a copying film in stacked relationship along a path of travel from said exposure section toward said developing section, means for separating the stacked films during movement thereof towards said developing section, said separating means including conveyor means between which the stacked films are conveyed, said conveyor means including a first conveyor on a first side of said path of travel for conveying a first of the films in a first direction along said path of travel, and said conveyor means further including a second conveyor on a second side of said path of travel opposite said first side for conveying a second of said stacked films in a second direction generally the same as said first direction but diverging relative thereto in the downstream direction thereby effecting separation of the stacked films by relative movement thereof laterally of the path of travel.
