<p>PROBLEM TO BE SOLVED: To provide a coordinate input device to be easily installed even in a thin space part near to the wall of a housing constituting a computer, an information equipment or the like. SOLUTION: Elastic depression pieces Px<+> , Px<-> , Py<+> , Py<-> are constituted at a 90 deg. interval by forming a slit S on the wall 1 of a housing for a computer, an information equipment or the like, variable capacitors Cx<+> , Cx<-> , Cy<+> , Cy<-> capable of changing electrostatic capacity by depression force from the pieces Px<+> , Px<-> , Py<+> , Py<-> are formed on parts opposed to respective pieces Px<+> , Px<-> , Py<+> , Py<-> and the electrostatic capacity values of respective variable capacitors Cx<+> , Cx<-> , Cy<+> , Cy<-> are converted into output voltage values Vx<+> , Vx<-> , Vy<+> , Vy<-> .</p> |
