Claims

[Claims for Utility Model Registration] (1) Electrodes extending parallel to both ends of each of the resistive films of a first resistive sheet and a second resistive sheet having resistive films are formed so that the respective electrodes are perpendicular to each other. The first resistance sheet is stacked above the second resistance sheet at a predetermined interval, and the first resistance sheet and the second resistance sheet are placed on a rigid receiving plate, In a coordinate input device that is provided with a switch part that is turned on and off by pressing force below the receiving plate, the switch part has two conductive sheets each having a conductive film facing each other with a predetermined interval between the two conductive sheets. A plurality of protrusions are arranged on either the underside of these two conductive sheets or between the two conductive sheets and the receiving plate, and the first resistor By applying a pressing force to the sheet, both the resistive films of the pressing part come into contact, and only when a larger pressing force is applied, both the conductive films come into contact at the place where the protrusion is arranged near the pressing part. A coordinate input device characterized in that it is configured to. (2) The coordinate input device according to claim (1), wherein the plurality of protrusions are made of an elastic material. (3) The coordinate input device according to claim (1), characterized in that the size of the plurality of protrusions is small at the center of the input surface and large at the outside. (4) The coordinate input device according to claim (1), characterized in that the plurality of protrusions are arranged sparsely in the center of the input surface and densely arranged on the outside.
