PROBLEM TO BE SOLVED: To provide a portable information device where the ratios of vertical lengths to horizontal lengths are the same between a folded state and a developed state.SOLUTION: Vertically long rectangular displays 10a, 10b, 10c are respectively arranged on the front surfaces of blocks A, B, C. The blocks A, B, C are mutually joined by hinges so that the blocks A, B, C can be folded or developed. The displays 10a, 10b, 10c arranged in the blocks A, B, C are flatly arrayed so as to constitute one screen in a state where the blocks A, B, C are turned and developed. When the blocks A, B, C are turned to be in a folded state, folding is performed to have the size of the block A and also the display 10a arranged in the block A is allowed to be a main screen. |
