PURPOSE:To perform the producing/editing processes of documents regardless of the state of an external memory by giving an answer to the inquiry received from a processor which performs the document producing/editing processes in terms of propriety for use of an external memory. CONSTITUTION:A processor 2 gives an inquiry to an external memory 4 when the document producing/editing processes are started. When the memory 4 is available, the document producing/editing jobs are carried out for the document files stored in a main memory 3 and the memory 4. If the memory 4 is not available, the documents are produced and edited for the memory 3 only. Thus the document processing/editing processes are possible even in case the memory 4 is not available.
