Abstract: The present invention relates to a resizable wireless pointing device with a storable receiver. The body housing comprises at least one inner compartment which is located next to the back of a wheel and used for storage of said wireless receiver. A sliding cover, located on the top of said body housing, which slides back and forth along the longitude axis of the housing and subsequently alters the size of the wireless pointing device. A shutter, which rolls up following the sliding of the cover, closes seamlessly the gap area between the body housing and the cover, and integrates into the surface of the wireless pointing device.

Abstract: A pointing device includes a casing in which a track ball is rotatably received and physically engaging two substantially perpendicular rotatable axles and a biasing structure forcibly biasing the track ball toward the axles. The biasing structure includes a frame rotatably supported inside the casing by pivots and a retainer mounted to the frame. The retainer includes a plurality of pawls spaced along a circumference to form a space for rotatably receiving and retaining a sphere. A biasing element is arranged between the casing and the frame to bias the sphere to forcibly engage the track ball thereby forcing the track ball against the rotatable axles.
