Abstract
A variable magnification copying machine comprises original size input means for inputting a size of an original, a paper size input means for inputting a size of a copy paper and a copy magnification calculation means for calculating a copy magnification factor based on the original size and the paper size. The copy magnification factor is calculated selectively based on widths in one direction of the original and the paper or based on widths in the other direction of the original and the paper.
Claims19
A variable magnfication copying machine comprising:
- original size input means for inputting a size of an original;
- paper size input means for inputting a size of a copy paer;
- and
- determination means for determining a magnification factor based on the original size and the paper size, said determination means including first determination means for determining a first magnification factor based on first direction widths of the original and the paper, second determination means for determination a second magnification factor based on second direction widths of the original and the paper, and selection means for selecting between said first determination means and said second determination means.
A variable magnification copying machine comprising:
- original size input means for inputting a size of an original;
- paper size input means for inputting a size of a copy paper;
- and
- determination means for determining a magnification factor based on the original size.and the paper size, said determination means including first determination means for determining a first magnification factor based on first and second direction widths of the original and first and second direction widths of the paper, second determination means for determining a second magnification factor based on first or second direction widths of the original and the paper, and selection means for selecting between said first determination means and said second determination means.
A variable magnification copying machine comprising:
- an original mount member for mounting an original thereon;
- reading means for reading a size of the original mounted on said original mount member to generate a reading signal;
- A/D converter means for A/D converting the reading signal from said reading means;
