摘要： A beam-directed structure of an input device comprises a light source, a first lens, and a vision-detecting element. The light source provides a projecting beam. The bottom of the first lens has an arch, which is on the path of the projecting beam. The arch adjusts the beam's slope, and the normal of the arch of the first lens is perpendicular to the surface of the object to let the beam focus on the bottom of the first lens and be projected to the surface of the object. The vision-capturing path passes the first lens exactly from the surface of the object and enters the upper part of the first lens. The vision-detecting element mounted on the upper part of the first lens is used to collect the vision from the surface of the object. By focusing on the surface of the object via the first lens, the vision-detecting element can clearly read the vision of the object.

摘要： A multiple function optical image detecting structure includes a shell body, a tracing ball, an optical base, a circuit board, a light-emitting element, and an image sensor. The shell body receives the tracing ball. The optical base has a slanted spectroscope that faces part of the spherical surface of the tracing ball and a lens element located on one side of the spectroscope. The light-emitting element and the image sensor are electrically connected with the circuit board. The light-emitting element faces towards the spectroscope and the image sensor faces towards the lens element. The light axial of the projected light generated from the light-emitting element is reflected/transmitted to the surface of the tracing ball via the spectroscope. Thereby, the light is uniformly projected on the tracing ball and the image sensor obtains the image on the lens element to calculate a displacement.

摘要： A light apparatus of an optical mouse with an aperture stop and the light projection method thereof are described. The light apparatus has at least one image-forming lens and an aperture stop. The image-forming lens defines an interior area and an external area. The aperture stop has a pupil. The aperture stop shelters the external area of the image-forming lens. The pupil of the aperture stop corresponds to the interior area. The present light apparatus will not produce a light halo on the image detection unit of the optical mouse when the light source of the optical mouse projects a light that passes through the image-forming lens of the light apparatus. Therefore, the image detection unit clearly detects the image of the image detection surface.

摘要： A dust-cleaning apparatus for a tracking ball includes a cover, a seat body, a tracking ball, and a dust-cleaning textile. The tracking ball rolls inside the seat body that is combined with the cover. Furthermore, a partially spherical surface of the tracking ball is exposed out of the seat body. The dust-cleaning textile is disposed between the seat body and the cover and has a hole for the tracking ball to pass through and compactly contact the dust-cleaning textile. Due to the compact contacting with the tracking ball, the dust-cleaning textile prevents foreign matter from attaching on to the spherical surface of tracking ball or from entering the seat body. Moreover, foreign matter is isolated outside the seat body so that the tracking ball can be used normally.

摘要： An optical mouse light emitter has a transparent body, a divergent light-emitting component and a disc reflective structure. The transparent body has a front end surface and a lateral circular surface. The light-emitting component is built in the transparent body. The disc reflective structure is built on the lateral circular surface. The disc reflective structure has an internal surface. The light emitted from the light-emitting component through the front end surface of the transparent body forms a light collection area. The light emitted from the light-emitting component to the internal surface of the disc reflective structure is reflected by the internal surface to form an axial parallel light and focused at the light collection area for reducing the light interference and enhancing the illumination so as to improve the light sensing effect of the optical mouse, lower its cost and reduce its electric power consumption.
