Abstract
A wireless stylus includes a pocket clip having a latch which, upon insertion into a storage compartment within a digitizer, engages a cam. The cam has a shape that causes the latch to move into engagement with a keeper as the stylus is pushed into the compartment and then released. The keeper holds the stylus in a stored position. The latch is released upon first pushing the stylus and then releasing it. Biasing means engages the stylus and moves it against the keeper and ejects the stylus outwardly from the storage compartment allowing the stylus to be grasped and withdrawn from the tablet. The storage compartment is open at opposite ends and has two cams, one at each end of the compartment so that the stylus, at the convenience of the user, can be inserted into either end for storage.
