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.
Claims7
In a reprographic camera including means for holding an original in a position to be exposed to illumination, an optical system comprising an objective in a light path from the original and means for holding light-sensitive material across said path beyond the objective, the improvement wherein said means for holding an original comprises a holder provided with at least two mounting surfaces onto each of which an original can be fitted, said holder being rotatable about an axis perpendicular to the optical axis of said optical system and being settable in a plurality of positions relative to its axis of rotation, in each of which one of said surfaces lies in a path of illumination and faces the optical system and is perpendicular to its optical axis, the distance between said axis of rotation and one of said mounting surfaces being smaller than the distance between said axis of rotation and a second of them, whereby the reproduction ratio of an original mounted on said second surface is greater than that of an original mounted on said one surface.
