Abstract
PURPOSE: To let the operator's operation simply necessitate depressing a button by detecting or discriminating the size of the original and copy size set to the copying machine and letting an optical system automatically determine magnification rate.
CONSTITUTION: The device is so constituted that a magnification operator 11 which outputs command signal is provided to the driving control part 2 controlling the variable power driving part 1 of the optical system and that an original size detecting mechanism 12 or original size discriminating mechanism 13 which turns on the data D1 of original size and a copy size set operating mechanism 13 or copy size discriminating mechanism 15 which turns on the data D2 of copy size is provided to the operator 11. Hence, as the copy start is commanded at proper times, the magnification operator 11 immediately follows up and automatically commands the new magnfication rate value to the drive control part 2 even if the original size changes, thus always normal copying operation may be obtained.
