ABSTRACT:
A hand held computer having a display screen which accepts writing from an electronic pen-type stylus has a cord which tethers the stylus to the computer. At the periphery of the computer is a flange or ledge forming a peripheral groove within which the cord resides when the stylus is stored in another wider part of the peripheral groove. The groove has a widened notch for receiving a larger-diameter portion of the stylus, such that the stylus snaps into a prescribed position lengthwise in the groove. In a preferred embodiment the cord is connected into the stylus via an internal spring in the stylus. The stylus thus gives some resiliency when pulled against the cord, and this feature is used to tightly seat the stylus in the groove or channel recess so that it is stored with the cord under some tension.
