Inventor: TAKENOUCHI SHIGEO
IPC: G06F17/21
Filed: 1983-09-20
Abstract: PURPOSE:To provide a memo column at the fringe of the standard document paper for free writing of an operator by using three types of pointers for document, editing and print to control three areas for document, editing and print respectively. CONSTITUTION:An operator designates the sizes of paper through an input part 1 for a document area 14, an editing area 15 and a print area 16 respectively prior to production of documents. Thus the values are set to a documents pointer 11, en editing pointer 12 and a print pointer 13 in accordance with each paper size. In other words, the area 14 can have the value larger than the paper size needed actually by the operator. The difference of size between areas 14 and 15 is used as a free writing area 17 which can freely store memorandum, etc. Thus it is possible to have a memorandum column at the fringe of a standard document paper for free writing of the operator by using three pointers for control of said three areas.
