ABSTRACT:
A copying machine with a predetermined variable magnification range is capable of providing a wider range of magnification values. The copying magnification desired can be entered into the copying machine and if the desired magnification data is out of the predetermined range, the machine can automatically calculate the number of times that a copy must be made and can also determine the magnification ratio for each copy to produce the desired final magnification value. The number of times that the copying process must be repeated with the copying paper being used as an original for each process can be displayed to the operator.
