Abstract

A clip-on pointing device (10) attaches to the front of a portable computer. The pointing device connects directly with circuitry internal to the computer by means of a connection port formed on the front of the computer. In one embodiment, the pointing device attaches to the computer by means of a mounting clip (140) which comprises a unitary sheet of metal. The mounting clip (140) includes a top arm (142) and a bottom arm (202) which provide a spring tension when flexed. The top arm (142) includes a gripping rail (144) which engages with a ridge on the frame of the computer. The bottom arm (202) includes a plurality of gripping tabs (210) which engage with slots (225) formed on the underside of the computer. The mounting clip (140) slides onto the front of the computer and snaps into place by virtue of the spring tension produced within the top and bottom arms of the mounting clip. Due to the thinness of the mounting clip (140), and the direct connection between the pointing device and the internal circuitry of the computer, the computer may be closed and carried without detaching the pointing device from the front of the computer. <IMAGE>
