Abstract
Abstract An image recording apparatus wherein image information is developed by converting the image information into an optical signal and by writing the image information on a drum-shaped image retainer with the converted optical signal to provide latent images and by developing the latent images, which are then recorded. A first writing timing is set in a first writing direction with respect to the image retainer and a second writing timing is set in a second writing direction with respect to the image retainer and the number of rotations with respect to the image retainer is calculated in accordance with the settings of the writing timings. The image information is overwritten by a number of times corresponding to the number of rotations to provide a plurality of images which may be entirely or partially or not superposed on one another.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
164 words
An image recording apparatus having a reading portion for reading an image information and converting the image information photoelectrically into an image signal and having a recording portion for writing the image information on a rotatable drum-shaped image retainer with said image signal to provide latent images, and developing the latent images, which apparatus comprises: first timing setting means for setting a writing timing in a first writing direction with respect to said image retainer; second timer setting means for setting a writing timing in a second writing direction with respect to said image retainer; and calculating means for calculating the number of rotations of said image retainer to be effected in accordance with the settings of the first and second writing timing setting means. wherein said image information is overwritten on said image retainer by a number of times corresponding to said number of rotations to provide a plurality of images which may be entirely or partially or not superposed on one another.
Claim 2
Dependent Claim
164 words
An image recording apparatus having a reading portion for reading an image information and converting the image information photoelectrically into an image signal and having a recording portion for writing the image information on a rotatable drum-shaped image retainer with said image signal to provide latent images, and developing the latent images, which apparatus comprises: first timing setting means for setting a writing timing in a first writing direction with respect to said image retainer; second timer setting means for setting a writing timing in a second writing direction with respect to said image retainer; and calculating means for calculating the number of rotations of said image retainer to be effected in accordance with the settings of the first and second writing timing setting means. wherein said image information is overwritten on said image retainer by a number of times corresponding to said number of rotations to provide a plurality of images which may be entirely or partially or not superposed on one another.
Claim 3
Dependent Claim
35 words
An image recording apparatus according to claim 1, wherein said reading portion scans in main and auxiliary directions and wherein said first writing direction is selected in the main scanning direction of the reading portion.
Claim 4
Dependent Claim
35 words
An image recording apparatus according to claim 1, wherein said reading portion scans in main and auxiliary directions and wherein said second writing direction is selected in the auxiliary scanning direction of the reading portion.
Claim 5
Dependent Claim
188 words
An image recording apparatus having a reading portion for reading an image information and converting the image information photoelectrically into a magnifiable image signal and having a recording portion for writing the image information on a rotatable drum-shaped image retainer with said image signal to provide latent images, and developing the latent images, which apparatus comprises: first timing setting means for setting a writing timing in a first writing direction with respect to said image retainer; second timing setting means for setting a writing timing in a second writing direction with respect to said image retainer; and calculating means for calculating the number of rotations of said image retainer to be effected in accordance with the settings of the first and second writing timing setting means, wherein said first and second writing timings are automatically set in accordance with a designation of a magnification, and wherein said image information is overwritten on said image retainer at the designated magnification by a number of times corresponding to said number of rotations to provide a plurality of images which may be entirely or partially or not superposed on one another.
Claim 6
Dependent Claim
188 words
An image recording apparatus having a reading portion for reading an image information and converting the image information photoelectrically into a magnifiable image signal and having a recording portion for writing the image information on a rotatable drum-shaped image retainer with said image signal to provide latent images, and developing the latent images, which apparatus comprises: first timing setting means for setting a writing timing in a first writing direction with respect to said image retainer; second timing setting means for setting a writing timing in a second writing direction with respect to said image retainer; and calculating means for calculating the number of rotations of said image retainer to be effected in accordance with the settings of the first and second writing timing setting means, wherein said first and second writing timings are automatically set in accordance with a designation of a magnification, and wherein said image information is overwritten on said image retainer at the designated magnification by a number of times corresponding to said number of rotations to provide a plurality of images which may be entirely or partially or not superposed on one another.
Claim 7
Dependent Claim
35 words
An image recording apparatus according to claim 4, wherein said reading portion scans in main and auxiliary directions and wherein said first writing direction is selected in the main scanning direction of the reading portion.
Claim 8
Dependent Claim
35 words
An image recording apparatus according to claim 4, wherein said reading portion scans in main and auxiliary directions and wherein said second writing direction is selected in the auxiliary scanning direction of the reading portion.
Claim 9
Dependent Claim
28 words
An image recording apparatus according to claim 4 or 5 or 6, wherein the writing magnification is automatically set by setting the number of rotations to be effected.
