A figure coordinate marking apparatus having a fine movement device capable of easily and accurately adjusting the marker to a specific coordinate position of a figure and a marker capable of clearly indicating a marking point. The figure coordinate marking apparatus comprises a main body having rollers provided at each end of a straight horizontal axle perpendicular to a running direction thereof so that the main body can run in only the straight running direction, a display device, an input device, and calculating means. A measuring lever is pivotably supported on the main body to rotate right or left relative to the running direction on a horizontal plane. A first wheel for fine movement in the substantial running direction of the main body, and a second wheel for fine movement in a turning direction of the measuring lever are provided. The first wheel and second wheel are normally kept a small distance above a sheet of paper on which a figure to be measured is drawn, by an elastic member. |
