1. An optical mouse comprising:
- a base plate, an optical navigation sensor including an optical element, the optical navigation sensor mounted to the base plate, an orifice proximal to the optical element, a plenum connected to the orifice, and air directing means for converting mouse operation into air flow through the plenum to the orifice and across the optical element.

Abstract
Reduction of dust contamination in optical mice. Operation of the mouse is adapted to direct air past optical surfaces, removing accumulated contaminants. In one aspect, lifting and resetting the mouse directs air through a funnel-like opening to a duct at the side of the optical surface. In a second aspect, mouse button motion is coupled to displace air past optical surfaces.
