Abstract

An automatic inclination device for a portable or notebook computer. It includes: (a) a base, on which an operation board is mounted; (b) a cover, pivotally connecting on an axis to a portion of the base; (c) a driving element, which is fixed to the cover and is coaxial with the axis, such that the driving element rotates when the cover is pivotally opened or closed; and (d) a driven element, engaged with the driving element to move therewith. The driven element is structured to move a stand to either come out from a cavity formed under the base near the pivotal portion so as to cause an associated portion of the base to rise up and the operation board to be in an inclined position, or retrieve into the cavity when the cover is opened and closed, respectively. In a preferred embodiment, the driving element is a ring gear the driven is a rack gear, and the stand is an extension of the rack gear.
