Optical mouse

摘要

Disclosed is an optical mouse which can move a cursor on a display screen of a computer system by varying arrangement of optical parts and structures using regularly reflected light in light emitted from a light source so as to allow the regularly reflected light to enter into a sensor. The optical mouse includes a light source for emitting light, an irradiating lens for condensing the light emitted from the light source and downwardly irradiating the light at a predetermined angle, a light-receiving lens for condensing light regularly reflected upon a reflecting surface on a path where light emitted from the light source and irradiated through the irradiating lens is reflected, and an optical sensor for sensing the light condensed through the light-receiving lens.
