Abstract
Abstract An image formation apparatus includes an input device that is used to enter a desired magnification factor for the image to be formed by the apparatus. If the apparatus is a copying apparatus, the input device can also be used to select the desired number of copies. The apparatus has a display device that displays to an operator the magnification factor. Control circuitry ensures that the display device shows the desired magnification factor.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
74 words
An image formation apparatus comprising: input means for entering a desired magnification factor and a desired number of sheets of copy; display means for displaying said magnification factor; and control means for controlling said display means so that said display means displays said magnification factor according to said input means, said control means including discriminating means for discriminating whether or not the magnification factor entered from said input means is within a predetermined range.
Claim 2
Dependent Claim
74 words
An image formation apparatus comprising: input means for entering a desired magnification factor and a desired number of sheets of copy; display means for displaying said magnification factor; and control means for controlling said display means so that said display means displays said magnification factor according to said input means, said control means including discriminating means for discriminating whether or not the magnification factor entered from said input means is within a predetermined range.
Claim 3
Dependent Claim
33 words
An image formation apparatus according to claim 1, further comprising a switch for changing over the setting of the magnification factor or the number of sheets of copy, according to said input means.
Claim 4
Dependent Claim
18 words
An image formation apparatus according to claim 1, further comprising selecting means for selecting a preset magnification factor.
Claim 5
Dependent Claim
20 words
An image formation apparatus according to claim 1, further comprising display means for displaying said number of sheets of copy.
Claim 6
Dependent Claim
33 words
An image formation apparatus according to claim 1, wherein said control means inhibits display of said magnification factor when the magnification factor entered from said input means is outside of said predetermined range.
