ABSTRACT:
Controlled-distortion photocopying apparatus comprises a bifurcate drive mechanism the forks of which are angularly adjustable with respect to each other. Each fork propels a film carriage along a path normal to an exposure slit provided in a film mask disposed between the film carriages and a light source. A transparency to be copied is carried beneath the exposure slit by one carriage and a sensitized film carried beneath the transparency by the other carriage. The dimension of the photocopy normal to the long dimension of the exposure slit is either decreased or increased according to which carriage carries the sensitized film and which the transparency; the magnitude of the dimensional change depending upon the angle between the forks of the drive mechanism.
