Abstract
Abstract A digital copier is provided with mechanism for reading images of both sides of an original, and mechanism for storing image data read by the reading mechanism in an area of an image memory in order, and when a predetermined signal is applied thereto, for storing image data in the next area by one area. The predetermined signal may be generated when a skip key is depressed. Therefore, since it is not necessary to read images which needs not to be recorded, the appearance of the recorded images on a record sheet is improved and the processing time is shortened. The digital copier may be also provided with mechanism for storing blank data in remaining areas in the image memory when a predetermined signal is applied thereto. The predetermined signal may be generated when an end key is depressed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
356 words
A digital copier for recording a plurality of original images on a record sheet in accordance with contents in an image memory, said copier comprising; means for reading a plurality of original images of respective both sides of originals, which original images are to be recorded on a record sheet in such a manner that a plurality of front-side images of double-sided originals are set on a left side of said record sheet and a plurality of reverse-side images of double-sided originals are set on a right side on said record sheet, a front-side image and a reverse-side image of each original being set side by side; means for generating a first predetermined signal during successive reading operations of said reading means; means for generating a second predetermined signal during said successive reading operations; means for storing a plurality of said read original images in a plurality of memory areas of said image memory, in order of reading, for skipping one of said memory areas without said reading operations of said reading means, when said generated first predetermined signal is applied thereto, so as to store blank data in said skipped one of said memory areas, and for ending said reading operations of said readings means and storing operations of said storing means so as to store blank data in the remaining memory areas of said image memory when said second predetermined signal is applied thereto; and means for recording all of said image data in said image memory on said record sheet in such a manner that a plurality of front side images of double-sided originals are set on said left side and a plurality of reverse-side images of double-sided originals are set on said right side of said record sheet, a front side image and a reverse-side image of each original being set side by side and blank data being set, instead of one of a front-side image and a reverse-side image when said one of a front side image and a reverse-side image is not required to be copied or said record sheet is not filled with front and reverse-side images of originals.
Claim 2
Dependent Claim
