Abstract
Abstract An image reading apparatus, comprises an image reader to read images of a document; a rotation processor to conduct a rotation processing for image data obtained through reading by the image reader in accordance with inclination of the document; a memory in which image data subjected to rotation processing by the rotation processor are stored; and an external inputting device to input arbitrary rotation angles. When the rotation angles are inputted from the external inputting device, the image data obtained through reading by the image reader are subjected to the rotation processing in accordance with the inputted rotation angle and are stored in the memory.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
175 words
An image forming apparatus, comprising: an image reader to read images of a document; a rotation processor to conduct a rotation processing to correct inclination for image data obtained through reading by the image reader in accordance with inclination of a document; a memory in which image data which have been subjected to the rotation processing by the rotation processor; and an image forming device to form an image on a recording material based on the image data stored in the memory, wherein the image data which have been subjected to rotation processing by the rotation processor and image data obtained through reading by the image reader are stored in the memory, wherein the image forming device includes a trial mode to form a single set of recording sheets prior to plural sets of recording sheets, and wherein the image forming device forms in the trial mode a single set of recording sheets based on the image data which are stored in the memory after having been subjected to rotation processing by the rotation processor.
Claim 2
Dependent Claim
175 words
An image forming apparatus, comprising: an image reader to read images of a document; a rotation processor to conduct a rotation processing to correct inclination for image data obtained through reading by the image reader in accordance with inclination of a document; a memory in which image data which have been subjected to the rotation processing by the rotation processor; and an image forming device to form an image on a recording material based on the image data stored in the memory, wherein the image data which have been subjected to rotation processing by the rotation processor and image data obtained through reading by the image reader are stored in the memory, wherein the image forming device includes a trial mode to form a single set of recording sheets prior to plural sets of recording sheets, and wherein the image forming device forms in the trial mode a single set of recording sheets based on the image data which are stored in the memory after having been subjected to rotation processing by the rotation processor.
Claim 3
Dependent Claim
85 words
The image forming apparatus of claim 1 , further comprising: an external inputting device for inputting arbitrary rotation angles; wherein when the external inputting device inputs the rotation angles after the image forming device forms the single set of recording sheets in the trial mode, the rotation processor conducts the rotation processing for the image data stored in the memory in accordance with the inputted rotation angles and the image forming device forms an image based on the image data subjected to the rotation processing.
Claim 4
Dependent Claim
114 words
An image reading apparatus, comprising: an automatic document conveyor to convey a document onto a platen; an image reader to read images of the document conveyed by the automatic document conveyor and output image data of the document; an inclination detector to detect inclination angles of the document conveyed by the automatic document conveyor; an external inputting device to input arbitrary rotation angles to rotate the image data; and a rotation processor to conduct a rotation processing to rotate the image data of the document obtained by the image reader in accordance with both of the inclination angles detected by the inclination detector and the arbitrary rotation angles input by the external inputting device.
Claim 5
Dependent Claim
114 words
An image reading apparatus, comprising: an automatic document conveyor to convey a document onto a platen; an image reader to read images of the document conveyed by the automatic document conveyor and output image data of the document; an inclination detector to detect inclination angles of the document conveyed by the automatic document conveyor; an external inputting device to input arbitrary rotation angles to rotate the image data; and a rotation processor to conduct a rotation processing to rotate the image data of the document obtained by the image reader in accordance with both of the inclination angles detected by the inclination detector and the arbitrary rotation angles input by the external inputting device.
Claim 6
Dependent Claim
27 words
The image reading apparatus of claim 3 , further comprising: a memory which stores the image data that is subjected to rotation processing by the rotation processor.
Claim 7
Dependent Claim
22 words
The image reading apparatus of claim 4 , wherein the image data obtained by the image reader is stored in the memory.
Claim 8
Dependent Claim
36 words
The image reading apparatus of claim 3 , further comprising: a controller which controls the rotation processor such that when the automatic document conveyor is not used, the rotation processor does not conduct the rotation processing.
