Abstract

Abstract When images on the front and rear sides of multiple originals are reduced in size and recorded onto both sides of a single recording sheet in composite form, recording positions of images on the front and rear sides of each original are determined such that reduced images on the front side of the original are recorded on the front side of the recording sheet and reduced images on the rear side of the same original are recorded at corresponding positions on the rear side of the recording sheet. As a result, when the recording sheet is cut into pieces corresponding to respective recorded images, images on the front and rear sides of each cut piece of the recording sheet respectively agree with images on the front and rear sides of each original.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 161 words
A copying apparatus comprising: document feeding means for transporting multiple original documents to an exposure position; reading means for reading images of front and rear sides of the original documents at the exposure position; a memory for storing the images read by said reading means; image forming means for recording onto both sides of a recording sheet the images stored in said memory; and determining means for determining layouts of the images of the front and rear sides of the multiple originals on the recording sheet so that images of the front and rear sides of each of the multiple originals are respectively recorded at corresponding positions of the recording sheet back to back with each other, and so that the images of the front side of the originals are composed and recorded on the front side of the sheet and the images of the rear side of the originals are composed and recorded on the rear side of the sheet.
Claim 2
Dependent Claim 161 words
A copying apparatus comprising: document feeding means for transporting multiple original documents to an exposure position; reading means for reading images of front and rear sides of the original documents at the exposure position; a memory for storing the images read by said reading means; image forming means for recording onto both sides of a recording sheet the images stored in said memory; and determining means for determining layouts of the images of the front and rear sides of the multiple originals on the recording sheet so that images of the front and rear sides of each of the multiple originals are respectively recorded at corresponding positions of the recording sheet back to back with each other, and so that the images of the front side of the originals are composed and recorded on the front side of the sheet and the images of the rear side of the originals are composed and recorded on the rear side of the sheet.
Claim 3
Dependent Claim 34 words
A copying apparatus according to claim 1, further comprising processing means for reducing in size the images read by said reading means, wherein the images stored by said memory have been reduced in size.
Claim 4
Dependent Claim 44 words
A copying apparatus according to claim 1, wherein said memory has an area for storing images to be recorded on the front side of the recording sheet and an area for storing images to be recorded on the rear side of the recording sheet.
Claim 5
Dependent Claim 20 words
