    • A plurality of document information is divided into intrinsic data concerning descriptive contents of a document and common data that includes attributes of the descriptive contents, and is stored within a memory. Based on the document processing instructions inputted from an input section, intrinsic data stored within the memory undergoes edit processing with an intrinsic operation unit; also, based on document processing instructions, multiple common data stored within the memory undergoes change processing with a common operation section. These processing results are mutually reflected by a conversion section, and based on this intrinsic data and common data, document images are display on an output display section. Then, a retrieve section, based on the attributes designated by the input section, retrieves, from the memory, document information that possess these attributes, and displays this information on the display section.
