Abstract
A portable data processing apparatus such as a personal computer comprising in series a base portion, a top cover portion, a display housing portion, and a keyboard portion. These portions are pivotally connected one after another by first, second and third hinge means, respectively. The first, second and third hinge means are parallel to each other, so that the apparatus can adopt a spread position in which the keyboard portion and the display housing portion are spread to the front and a retracted position in which the keyboard portion overlaps the display housing portion. The top cover portion, the display housing portion, the keyboard portion, and the base portion are folded in a face-to-face relationship in the retracted position.
