Apparatus for combining divided portions of larger image into a combined image
First Claim
1. A copying machine for scanning a large document of a first size and printing it on a printer, in which a latent image on a photosensitive body is developed by a developing device and is transferred onto a sheet of paper, the copying machine comprising:
- a scanner having a scanning area of a second size which is smaller than the first size, the scanner constituting means for scanning every portion of a whole area of the large document and for producing a scanning signal representative of the area thus scanned;
a memory having a storage capacity for holding data representative of a document of a third size;
a magnifier for adjusting by a magnification ratio a size of an image represented by the scanning signal to fit within the storage capacity of the memory, the magnification ratio being adjusted while taking into account not only the storage capacity of the memory but also the maximum size of the printer; and
the printer, for printing a document of a fourth size by reproducing in eye-readable form the data held in the memory.

Abstract
An image combining device scans an image on a large document and prints it. The device includes a memory for storing image signals. In accordance with a first aspect of the device, a scanner scans areas of the document which are individually smaller than the area of the entire document, but combines the areas so as provide an eye-readable representation of the image which was on the large document. This is achieved quickly and efficiently by adjusting a magnification ratio applied to scanned image data, so as to allow the data to fit within the memory. In accordance with another aspect of the device, the combination of the images and the printing of the output are achieved by compressing image data using a binarization processor.
