Claims

[Claims for Utility Model Registration] A pencil is moved based on drawing data including drawing line type and drawing line length data, and a writing pressure set by a writing pressure setting means for setting writing pressure is applied to the pencil. , in a pencil plotter that can draw a drawing line with a drawing density according to the pen pressure, it is determined whether the drawing line type is a continuous straight line that does not change the direction of the tip of the pencil based on the drawing line type data. drawing line type determining means for determining the drawing line type; drawing line length determining means for determining whether the drawing line length exceeds a predetermined reference length based on the drawing line length data; a drawing movement distance detection means for detecting a drawing movement distance of the pencil from a starting point to a drawing end point; and a drawing line type determining means that determines that the drawing line type is the continuous straight line and the drawing line length. If the determination means determines that the drawing line length exceeds the reference length, the drawing movement distance from the drawing start point to the drawing end point increases as the drawing movement distance detected by the drawing movement distance detection means increases. The writing pressure compensation means controls the writing pressure setting means so as to increase the writing pressure and set a second writing pressure at the drawing end point that is higher than the first writing pressure at the drawing starting point.
