ABSTRACT:
A method for controlling positions of reproduction pictures on a recording film mounted to a recording cylinder in the direction of the cylinder's axis, for use in a picture reproducing machine, wherein distances of pickup and recording heads away from a scanning start point of each original picture and a recording start point of each reproduction picture are detected on the basis of a standard position through which the recording head is moved at a fixed speed, and wherein the moving speed of the pickup head is controlled according to the distances detected and each reproduction scale so that the scanning start point of the original picture and the recording start point of the reproduction picture may be scanned at substantially the same time by the pickup and the recording heads.
