<p>PROBLEM TO BE SOLVED: To provide a key input device capable of improving switch operability, reducing costs, and realizing miniaturization and weight reduction even in a configuration that switches are arranged at the back side of a display panel. SOLUTION: A liquid crystal display panel 13 is supported so as to be inclined with the top end of a protrusion 14 of the liquid crystal display panel 13 as a supporting point, and input switches e1, e2, e3, and e4 are arranged on the back side of the liquid crystal display panel 13. When the site of the liquid crystal display panel 13 overlapped with any of those input switches is depressed, the liquid crystal display panel 13 is inclined, and any of projecting parts 16-1, 16-2, 16-3, and 16-4 is moved, and any of those input switches is turned on.</p> |
