Abstract:
1. An optical mouse system comprising: a printed circuit board, having at least a first surface on which components are mounted; an illumination source where an axis of the illumination source is parallel to a vector normal to the first surface of the printed circuit board; a sensor, having a sensing surface comprising an array of sensing elements, where a vector normal to the sensing surface is parallel to a vector normal to the first surface of the printed circuit board; an illumination guide, for directing illumination from the illumination source to a reference surface at an angle of less than about thirty-three degrees from a normal vector to said reference surface when said reference surface is parallel to the first surface of the printed circuit board, and for redirecting scattered illumination from said reference surface toward the sensing surface of the sensor, said illumination guide comprising a first mating surface and a second mating surface; a holder, having a first surface and a second surface, comprising: where the first surface of the holder is disposed against the first surface of the printed circuit board; and a containing clip, comprising: where the containing clip encloses the holder and illumination guide and shields the sensor from external ambient illumination.
