PURPOSE: To execute the input of coordinates and the operation of respective function switches with one hand by obtaining the multi-layer structure of a coordinate input part and respective function switch parts for a pad for coordinate input and causing respective input load sensitivity to be different.
CONSTITUTION: For respective pressure sensitive conductive sheets 4 an 18 of a coordinate input part 13 and a switch part 19, input loads F1 and F2 are different to arrive at a conductive resistance value R. Now, when the surface of a pad part 20 for coordinate input is pressed by a pen with the load of 120g/0.5ϕ, pressurizing force is added to the pressure sensitive conductive sheets 4 and 18, however, only the pressure sensitive conductive sheet 4 goes to a conductive condition. Then, coordinate data are inputted through an A/D converting part to an arithmetic part 6. In such a condition, when the pressing force by the pen is 170g/0.5ϕ, for example, the pressure sensitive conductive sheet 19 also goes to the conductive condition and a determined switch signal is inputted from the switch part 19 to the arithmetic part 6.
