Abstract

PURPOSE:To omit driving of the document file for every taking of hard copy, by storing all of information read from the document file into the frame memory and by reading this information according to the speed of hard copy and soft copy. CONSTITUTION:All of information read from document file 3-1 is stored in frame memory 3-3 and is read according to the speed of soft copy and hard copy. Here, memory 3-3 is divided into four blocks independent of one another; and when document information is indicated by expression I, blocks (brs)1, (brs)2, (brs)3, and (brs)4 are expressed by (a2r-12s-1), (a2r-12s), (a2r2s-1), and (a2r2s) respectively. However, r=1, 2...p and s=1, 2...q are true. Four blocks are read simultaneously for read from memory 3-3 to obtain the soft copy signal of (Crs) expressed by expression II. As a result, driving of the document file for every taking of hard copy can be omitted.
