<p>PROBLEM TO BE SOLVED: To make the device very thin and lightweight and to carry it in a pocket by providing a liquid crystal display part with a keyboard in a free opening/closing state and arranging a main body control part in a liquid crystal control part. SOLUTION: The keyboard has the flexible hinge part of its exterior case constituted so that it can be curved at the time of storage. The contact area of the main body to a liquid crystal display 3 on the top surface of the control board is a component unmounted area, a segment substrate electrode 27 and a common substrate electrode 28 are formed corresponding to a segment-side transparent electrode 25 and a common-side transparent electrode 26 of the liquid crystal display 3, and a liquid crystal control part 29 including a driving driver which drives the segment side and common side of the liquid crystal display 3 is mounted on the reverse surface of the control substrate 14 controlling the liquid crystal display part 29 together with a keyboard control part 30. Thus, the keyboard control pat 30 is arranged on the control substrate 14 on the liquid crystal display control side together with the liquid crystal control part 29 to greatly reduce the thickness of the device.</p> |
