INPUT DEVICE AND MOBILE TERMINAL

摘要

In order to increase operability when operating a desired key, an input device is provided which has a plurality of keys arranged in a plurality of rows, each key comprising an operation screen on which a key display mark (211) is written and a capacitive touch sensor electrode plate (221) disposed on the back thereof. Each electrode plate (221a, 221b) forms a V-shape wherein the top edge and the bottom edge thereof protrudes downwards such that the center of gravity for each electrode plate is positioned further on the bottom side of the row direction than the center of a minimum rectangular region that surrounds each corresponding key display mark, i.e., key display mark (211a) and key display mark (211b).
