Abstract
Abstract An erasure portion designation section designates position data corresponding to an arbitrary portion to be erased, which is not required to be copied, of the original placed on the original table. A memory stores the position data of the portion to be erased designated by the erasure portion designation section. The position data is stored in units of originals for a plurality of originals. A readout designation section designates the position data, corresponding to the portion to be copied of a plurality of originals stored in the memory, to be read out in correspondence with the original to be copied. An original scanning section optically scans the original to be copied placed on the original table to obtain an optical image. An image forming section receives the optical image obtained by the original scanning section and transfers an image corresponding to the optical image onto an image recording medium. An image erasure section receives the position data of the portion to be erased read out from the memory by the readout designation section and erases a corresponding portion of the image to be formed by the image forming section.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
112 words
A copying apparatus comprising: means for generating position data representing an image formation region in units of originals; means for storing data generated by said generating means; said storing means including primary means for temporarily storing the position data, and secondary memory means for storing the position data transferred from different areas in said primary memory means in units of originals; means for reading out the data stored by said storing means in accordance with the image formation region corresponding to each of the originals; and means for forming an image corresponding to each original within the image formation region in accordance with the data read out by said read out means.
Claim 2
Dependent Claim
112 words
A copying apparatus comprising: means for generating position data representing an image formation region in units of originals; means for storing data generated by said generating means; said storing means including primary means for temporarily storing the position data, and secondary memory means for storing the position data transferred from different areas in said primary memory means in units of originals; means for reading out the data stored by said storing means in accordance with the image formation region corresponding to each of the originals; and means for forming an image corresponding to each original within the image formation region in accordance with the data read out by said read out means.
Claim 3
Dependent Claim
15 words
An apparatus according to claim 1, wherein said secondary memory means includes nonvolatile memory means.
Claim 4
Dependent Claim
199 words
An electronic copying apparatus comprising: an original table for placing thereon an original to be copied; original scanning means for optically scanning the original to be copied placed on said original table to obtain an optical image; image forming means for receiving the optical image obtained by said original scanning means and transferring an image corresponding to the optical image onto an image recording medium; erasure portion designation means, for designating position data corresponding to at least an arbitrary portion to be erased, which is not required to be copied, of the original placed on said original table; storage means for storing the position data of the portion to be erased designated by said erasure portion designation means, the position data being stored in units of originals for a plurality of originals; readout designation means for designating the position data, corresponding to the portion to be erased of said plurality of originals stored in said storage means, and image erasure means for receiving the position data of the portion to be erased read out from said storage means by said readout designation means and erasing a corresponding portion of the image to be formed by said image forming means.
