Abstract
An input device and detection device each have separate electrodes with one electrode for detecting input in a vertical direction and a plurality of electrodes for detecting input in a horizontal direction. An elastic body has a conductive portion opposite to the electrodes with a thin portion opposite to the vertical-detection electrode. A storage depressed portion is formed on the thin portion. A space between the elastic body and the electrodes changes by input. A slider is connected to the elastic body and is movable only in a horizontal direction, a hard pressing body stored in the storage depressed portion of the elastic body, and a key top opposite to the pressing body and vertically movable. When the slider is moved horizontally, the elastic body deforms and the space between the conductive portion of the elastic body and the horizontal-detection electrodes changes, and when the key top is pressed, the thin portion of the elastic body deforms through the pressing body and the space between the thin portion and the vertical-detection electrode changes.
