COIL ARRANGING METHOD FOR DIGITIZER

摘要

The method increases the area of coil plate used to detect sine wave magnetic flux that is supplied from the stylus of an electromagnetic digitizer. This method comprises of the step of; setting each common-standarded potential line for x axis and y axis; connecting the first row of multiple coil lines at the same spacing in order to detect the position of stylus in the x axis and y axis common-standared potential line; forming the first position detecting plans by extending the multiple connected coil lines; connecting the other rows of multiple coil lines to a demultiplexer in order to detect the position of stylus; and forming ground coil lines whose other rows are connected to the demultiplexer, after extending to cover entirely any plane of the first position detecting plane and the second position detecting planes and connecting the first row of common-standarded potential line to the border between the first and second position detecting planes.
