Abstract

PURPOSE: To attain to reduce the number of elements by arranging so that the number of driving lines and the number of sense lines can be the product of the number of driving transistors and the product of the number of sense switches, respectively.
CONSTITUTION: The driving element groups D1WDm and D1'WDm' are connected to both the ends of the driving lines l1WlM of the tablet, also the sense switch groups S1WSn and S1'WSn' are connected to both the ends of the sense lines l1'WlN' in the same way, and the address circuit 18 generates the address of the input pen 14 by the output of the detection circuit, by setting the control circuit 11 by which any two are selected out of the driving elements and the sense switches which have been connected to both the ends of the aforesaid driving line and the sense line, respectively, indicating an optional position of the above-mentioned tablet with the input pen 14 consisting of a magnetic body or a conductor, amplifying the electromotive force inducing to the sense loop by the detection circuit, and detecting that the input pen 14 has indicated the optional position.
