A laptop personal computer (PC) is disclosed. The laptop PC includes a hinge unit that turns around a vertical axis and rotates around a horizontal axis, and the hinge unit connects a main body chassis to a display chassis. The hinge unit includes an inside, through which cables connecting a main body and a display pass. A path is provided, along which the cables are installed, and the path includes a part that is parallel to the vertical axis and is apart from the vertical axis and having a part overlapping with the horizontal axis towards the vertical axis. The cover is provided at the display chassis for covering the cables overlapping with the horizontal axis. This can eliminate the necessity of a cover for the cables on the side of the hinge unit, thus making the laptop PC thinner.
