<p>PROBLEM TO BE SOLVED: To more facilitate the use of a keyboard, to drastically increase comfortableness in typing, to reduce possibility of a trouble and to improve efficiency for a user by dividing the keyboard into keyboard parts and changing relative horizontal directions of the parts. SOLUTION: A computer 100 is provided with a first chassis part 110 and a second chassis part 120 connected with the first chassis part 110 by a hinged structure 142. The first and the second chassis parts 110, 120 are rotated in relation to each other between the hinged structure 142 and a closing position. The keyboard 150 is provided with a left keyboard part 160, a right keyboard part 170 and a direction determining device part 182. A track pad 183, a left and a right instant switches 185, 187 are beared by the direction determining device part 182. The shape of the track pad 183 is curved, i.e., more specifically, elliptic.</p> |
