To improve the operability in portable electronic equipment comprising a display unit and body unit having a display device and a keyboard, respectively, one-side ends of which are rotatably connected to be foldable and openable/closeable, by conpensating the reduction in operability by the contraction of the keyboard.

A jog dial 2 is provided in a position operable by an operator's thumb in a key input operation of the keyboard 3 on the side surface 11c of the end portion opposite to the hinge part 5 side of the body unit 11. According to this, the operability can be improved. Since the body unit 11 and the display unit 12 are connected so as to be rotatable substantially at 360° by the hinge part 5 of two-shaft structure, a touch panel provided to overlap with the display surface of a liquid crystal display device 4 in the closed state of both the units 11 and 12 is exposed to the outside so that an input operation in the touch panel can be performed while holding the touch panel with one hand.
