Claims5
In a copier adapted for composite copying, the improvement comprising means for effecting fine adjustments of magnification and means for automatically controlling said adjustment effecting means according to the change in size of copy paper caused by preceding copying process effected on said copy paper whereby non-uniformity in image size can be prevented when copying is effected twice or more on a single copy paper.
A copier comprising a zoom lens and means for effecting fine adjustments of magnification according to the change in size of copy paper caused by preceding copying process effected on said copy paper, said adjustment effecting means serving to move said zoom lens by a distance determined by the number of times copying has been effected on said single copy paper whereby non-uniformity in image size can be prevented when copying is effected twice or more on a single copy paper.
