<p>PROBLEM TO BE SOLVED: To provide an information input device which has high operability and has keys easy to change.SOLUTION: An information input device includes: a touch panel; and a keyboard which has a plurality of key tops which are constituted so as to be vertically movable in response to pressing force and have, on bottom surfaces thereof, projection patterns according to types of corresponding keys, and can be placed on the touch panel. When being placed on the touch panel, the keyboard can hold a first state where the bottom surfaces of the key tops are spaced from the touch panel and a second state where the bottom surfaces of the key tops are in contact with the touch panel. The touch panel detects a projection pattern on the bottom surface of the key top in the second state and performs key input corresponding to the detected projection pattern.</p> |
