In many cases, a graphic data input device using the mouse 50 or the trackball 60 has an arrow cursor (cross pointer) or a cross line depending on the coordinate position determined by the position of the mouse 50 on the table or the rotational position of the trackball 60. The cursor is displayed on the screen of the display device, and the button 52, 62 attached to the mouse 50 or the trackball 60 is clicked to specify the coordinate position. For example, in drawing a straight line, the mouse 50,
Operate the trackball 60 to move the cursor to the start point of the straight line, and when the cursor is located at the start point, click the buttons 52 and 62 and click and hold the mouse or move the cursor to move the cursor to the end point of the straight line. , Button 52, 62 click release.

In the device for inputting graphic data by the tablet 70, the cursor is not displayed. For example, in drawing a straight line, the position of the straight line starting point on the coordinate input surface 74 of the tablet boat 72 is pressed with the stylus pen 75, and the button of the stylus pen 76 is pressed. By pressing the 78 and moving the stylus pen 76 so as to write with the pen, input is performed by pen touch.

Further, as a pen-touch input device using a tablet, a cross-line cursor (right-angle scale line) is displayed on the screen at a position designated by a mouse arranged on the coordinate input surface of the tablet boat, and a stylus pen is used for pen-touching a figure. C that can input data
