ABSTRACT:
A reprographic camera for exposing an original to illumination that is passed through an optical system to light-sensitive material is provided with a holder having at least two mounting surfaces onto each of which an original can be fitted, and which is rotatable about an axis perpendicular to the optical axis of the optical system so that the holder can be set in a plurality of positions in each of which one of the mounting surfaces faces the optical system. One of the mounting surfaces is located at a greater distance than another from the axis of rotation of the holder so that the respective active positions of these surfaces are at different distances from the objective of the optical system, thus providing different reproduction ratios.
