Abstract
Abstract An image forming apparatus includes an original size input section for inputting an original size, a sheet size input section for inputting a sheet size, a variable magnification input section for inputting an arbitrary variable magnification, a selection section for selecting a variable magnification determination mode on the basis of a size relationship between the original size and the sheet size, a first display section for displaying the variable magnification input by the variable magnification input section, a second display section for preforming a mode display indicating that the variable magnification determination mode is selected, and a control section for controlling the first and second display sections. In this apparatus, the control section can simultaneously execute the display of the input variable magnification by the first display section and the mode display be the second display section.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
135 words
An image forming apparatus comprising: original size input means for inputting an original size; sheet size input means for inputting a sheet size; determination means for determining a first variable magnification in a first direction of a reproduced image on the basis of both the original size input through said original size input means and the sheet size input through said sheet size input means; magnification input means for arbitrarily inputting a second variable magnification in a second direction different from the first direction of the reproduced image; and reproduced image forming means for forming a reproduced image at mutually different variable magnifications relating to the first and second directions on the basis of the first variable magnification determined through said determination means and the second variable magnification arbitrarily input through said magnification input means;
Claim 2
Dependent Claim
135 words
An image forming apparatus comprising: original size input means for inputting an original size; sheet size input means for inputting a sheet size; determination means for determining a first variable magnification in a first direction of a reproduced image on the basis of both the original size input through said original size input means and the sheet size input through said sheet size input means; magnification input means for arbitrarily inputting a second variable magnification in a second direction different from the first direction of the reproduced image; and reproduced image forming means for forming a reproduced image at mutually different variable magnifications relating to the first and second directions on the basis of the first variable magnification determined through said determination means and the second variable magnification arbitrarily input through said magnification input means;
Claim 3
Dependent Claim
35 words
An apparatus according to claim 1, wherein said determination means has a first determination mode for determining a variable magnification on the basis of widths in a first direction of the original and the sheet.
Claim 4
Dependent Claim
61 words
An apparatus according to claim 2, wherein said determination means has a second determination mode for determining a variable magnification on the basis of widths in a second direction of the original and the sheet, the second direction being different from the first direction, and wherein said apparatus further comprises selection means for arbitrarily selecting the first or second determination mode.
Claim 5
Dependent Claim
58 words
An apparatus according to claim 1, wherein said forming means includes reader means adapted to scan the original and output an image signal, and to perform a variable magnification operation by changing a sampling rate of the image signal with regard to the first direction and by changing an original scanning speed with regard to the second direction.
Claim 6
Dependent Claim
33 words
An apparatus according to claim 1, wherein said magnification input means is capable of arbitrarily inputting the first and second magnifications relating to the respective first and second directions of the reproduced image.
Claim 7
Dependent Claim
129 words
An image forming apparatus comprising: original size input means for inputting an original size; sheet size input means for inputting a sheet size; selection means for selecting an automatic mode for automatically determining a first variable magnification in a first direction of a reproduced image on the basis of both an original size input through said original size input means and a sheet size input through said sheet size input means; mode display means for displaying the automatic mode selected through said selection means; and magnification input means for arbitrarily inputting a second variable magnification in a second direction different from the first direction of the reproduced image; wherein said mode display means displays a magnification arbitrarily input through said magnification input means as well as the automatic mode.
Claim 8
Dependent Claim
129 words
An image forming apparatus comprising: original size input means for inputting an original size; sheet size input means for inputting a sheet size; selection means for selecting an automatic mode for automatically determining a first variable magnification in a first direction of a reproduced image on the basis of both an original size input through said original size input means and a sheet size input through said sheet size input means; mode display means for displaying the automatic mode selected through said selection means; and magnification input means for arbitrarily inputting a second variable magnification in a second direction different from the first direction of the reproduced image; wherein said mode display means displays a magnification arbitrarily input through said magnification input means as well as the automatic mode.
Claim 9
Dependent Claim
84 words
An apparatus according to claim 6, wherein said selection means has first and second selection keys for selecting first and second determination modes, respectively, said first determination mode being for automatically determining a variable magnification on the basis of widths in a first direction of the original and the sheet, said second mode being for automatically determining a variable magnification on the basis of widths in a second direction of the original and the sheet, the second direction being different from the first direction.
Claim 10
Dependent Claim
33 words
An apparatus according to claim 6 wherein said magnification input means is capable of arbitrarily inputting the first and second magnifications relating to the respective first and second directions of the reproduced image.
Claim 11
Dependent Claim
21 words
An apparatus according to claim 6, wherein said display means is capable of displaying a numeral indicative of an input magnification.
