Abstract
Abstract In a copying machine, a predetermined part of image data read out of an original by an original reader is extracted and is temporarily stored as variable data to be edited in a first memory, while fixed data necessary for forming documents from the original are stored in a second memory, and data read out of the memories and new data inputted additionally by a data generator are combined selectively under the control of a control system to form the documents.
