Method of inputting digitalized, two value graphic pattern data of a character or a symbol into a memory device wherein, for the purpose of compressing the data representative of complicated graphic patterns of characters and symbols, the contour line of a graphic pattern is traced from a start point which may be selected from the intersections of the contour line with a reference line drawn across the graphic pattern, and the positional data of sampling points arranged along the contour line is sequentially detected along the contour line from the start point. Since the start point may be definitely selected from each contour line even when the graphic pattern is comprised of a plurality of closed-loop contour lines by drawing a necessary number of lines across the graphic pattern, the graphic pattern may be accurately represented by the coordinate values of the sampling points, arranged along the contour lines, without fail.
