In an mobile electronic equipment in which an upper cabinet is openably and closably coupled with a lower cabinet, cutout portions from which a track ball is exposed are formed to the coupling portions of the upper and lower cabinets, and the track ball is interposed between a pair of hinge mechanisms for connecting both the cabinets to each other. With this arrangement, since the track ball is exposed in any of the opened state and the closed state of the mobile electronic equipment, a user can manipulate the track ball in any of the opened state and the closed state. Accordingly, there can be overcome the disadvantageous operability of a conventional folding type mobile electronic equipment, which has a track ball as a pointing device, in that a job for opening the equipment is required to manipulate the track ball.
