Abstract:
1. A position-detecting device for detecting a position pointed to by a position-pointing instrument, comprising: an operation panel for performing a drawing operation; a detectable area comprising an xy coordinate system for detecting the position pointed to by the position-pointing instrument, the detectable area being adapted to detect the position pointed to by the position-pointing instrument by electromagnetic coupling using a first plurality of loop coils provided under the plane of the detectable area, wherein each loop coil extends parallel to the y-axis of the detectable area, and a second plurality of loop coils provided under the plane of the detectable area, wherein each loop coil extends parallel to the x-axis of the detectable area, wherein the area of said operation panel is defined by an entire area of intersection of said first and second plurality of coils, wherein the detectable area is larger than the operation panel because the first and second plurality of loop coils extend beyond said area of said operation panel, and wherein the detectable area interfaces with a display for displaying an image defined by the position pointing instrument; and manipulation-detecting means adapted to detect the manipulation by a user's finger, the manipulation-detecting means comprising a touch pad being adapted to detect a user's touching manipulation, said touching manipulation actuating at least one setting operation that modifies a visual appearance of the image being simultaneously generated on said display by said position-pointing instrument, the operation panel and the manipulation-detecting means being adapted to be used simultaneously, and wherein the manipulation-detecting means is located outside of said area of said operation panel and within said detectable area.
