Abstract
Improved structure for high resolution mouse is equipped with a frictional sleeve on each one of a pair of transmission shafts with transmission wheel circumferential length multiple of that of corresponding frictional sleeves so as to increase rotational ratio and facilitate an associated pair of infrared detectors able to detect bright/dark intermitten variation of light imput more distinctly and reliably from a pair of light shading wheels in a given time duration and send out corresponding high resolution (DPT) signals.
