<p>PROBLEM TO BE SOLVED: To improve the operability and to secure display quality by arranging a tablet as a coordinate input device on the reverse surface of the information terminal device and incorporating it rotatably on an axis of rotation. SOLUTION: When the information terminal device 1 is operated in a hand, a tablet unit 2 is positioned on the reverse surface of the information terminal device 1 and the tablet 3 is on the reverse side of an operation surface. While the information terminal device 1 is held in the hand, the holding fingers are always positioned on the operation surface of the tablet 3, so the tablet 3 is pressed and operated only by the operation of the finger tips without moving the hand. When the information terminal device 1 is placed on a desk top and operated, the finger tips are inserted into a recessed part 6a at the lower part of a housing 6 to lift the tablet unit 2 by touching the end part, the tablet unit 2 is released from being latched with a magnetic attracting force and rotated by 180 deg., and the operation surface of the tablet 3 is set faceup.</p> |
