<p>PURPOSE:To improve economization by transferring a coordinate value by means of a designated magnification. CONSTITUTION:When the suitable magnification is selected by a magnification designating switch SW, the coordinate value from a tablet device TD is transformed by a coordinate transforming means CD, and outputted to the input part of a computer main body C. For the main body C, the fixed magnification is displayed on a graphic display device GD according to an input value from the means CD. Thus, a simple graphic processing is executed by a graphic processing program to drive the display device GD according to the arbitrary variable magnification ratio, for the program of the main body C, the variable magnification program is eliminated, and only by connecting the device TD to a general simple personal computer PCS, as well, the arbitrary variable magnification rate can be obtained. Thus, the economization can be drastically improved.</p> |
