Abstract
An improved handle/prop is provided for a pen-based computer wherein the handle/prop is pivotally mounted to opposite side edges of the computer. The handle/prop can be pivoted and locked into a plurality of different positions. In particular, these positions are selected to facilitate carrying the computer, supporting the computer on a flat surface in one or more inclined positions for writing and/or viewing, and holding the computer during writing. A ratchet locking mechanism is provided for locking the handle/prop into the plurality of different positions. This ratchet locking mechanism includes first and second release buttons located at points where the handle/prop pivotally connects at opposite side edges of the computer. In addition, the ratchet locking mechanism includes a handle-tie piece extending through the interior of the computer to spring bias the release button into a locked position.
