<p>PROBLEM TO BE SOLVED: To realize click feeling with regard to input of two systems of switch input and operation input showing manipulated variable in a prescribed direction. SOLUTION: Electrode are formed on a printed circuit board 40, one metal dome 30-0 is put on the center and four metal domes 30 are put on the periphery of the printed circuit board, an elastically deforming body 20 made of silicone rubber, whose bottom surface is covered with a conductive layer is put on the printed circuit board 40, and an operation panel 10 is put on the printed circuit board 40. When pressing force is applied downward to the operation panel 10, the central metal dome 30-0 is turned reversely, electrodes E15 and E16 are electrically connected, and clock input is detected. When operation input is applied left aslant downward to the operation panel 10, the left side metal dome 30-2 is pushed flat, and the conductive layer beneath the elastically deforming body 20 becomes the same potential as the electrode E22. At that time, a capacitance value of a capacity element constituted with the electrodes E11, E12 and the conductive layer beneath the elastically deforming body 20 opposing to the electrodes is measured by utilizing the electrode E22 to detect operation input.</p> |
