Abstract
An improved copying apparatus provided with a variable magnification operation memory function, in which the data value setting operation is simplified in the case where the converted magnification copying work is repeatedly effected based on the same variable magnification operation data, and thus, working time is reduced, while generation of erroneous operation is prevented, with a reduction of running cost and an improvement of the working efficiency.
