ABSTRACT:
A reprographic camera is described having a table for an original subject, an objective and an image frame. One of these parts is fixed and the others are relatively movable to produce variable scale images or reproductions of the original. The movable parts are coupled via a transmission member which gradually changes the ratio of the lengths of their displacements throughout their ranges of movement.
