<p><P>PROBLEM TO BE SOLVED: To provide a coordinate detection device for precisely detecting coordinates in a wide range on a panel. <P>SOLUTION: In a touch panel 1, a coordinate axis x is set on a panel 1a by connecting a point A and a point B which are current observation points. When a specified point P is designated on the panel 1a, currents i1 and i2 in accordance with a distance between the specified point P and the point A and a distance between the specified point P and the point B are permitted to flow in resistance films between the points by voltage sources e1 and e2, and a sum of the currents flows into an impedance Z connected to the specified point P. The coordinate x of the specified point P is obtained by detecting the currents i1, i2. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
