[Claims for Utility Model Registration] A coordinate input unit using a surface resistance coordinate division method, which includes two overlapping coordinate input sheets and inputs coordinates by pressing the upper coordinate input sheet; an information processing circuit section for converting the output from the input section into predetermined coordinate information, and the coordinate input sheet divides the sheet resistance between the pair of main electrodes to which a voltage is applied into a plurality of resistances. The information processing circuit section includes an appropriate number of auxiliary electrodes, and includes a switch group for selecting any two electrodes from the main electrode and the auxiliary electrode on both coordinate input sheets, and an electrode selected by the switch group. A differential output circuit is connected to the differential output circuit to determine the potential difference, an A/D conversion circuit converts the analog information obtained by the differential output circuit to digital information, and when an input is made by pressing, the switch group A central processing circuit that controls opening/closing and processes signals passed through an A/D conversion circuit, and the central processing circuit selects electrodes adjacent to each other from among the plurality of electrodes on the coordinate input sheet. In addition, there is a judgment circuit that selects a pair of electrodes that sandwich the pressing position, and one of the pair of electrodes selected by the judgment circuit is used as a reference electrode, and the distance between this reference electrode and the pressing position is calculated as the potential difference on the sheet resistance. and an arithmetic circuit that determines the coordinates of the pressed position on the sheet by calculating based on the ratio and adding this distance and position information of the reference electrode on the coordinate input sheet. Characteristic coordinate input device.
