Abstract
This invention is directed to a device of “Invisible Infrared Laser Mouse” characterized by fixing a light emitter and an image sensor at the inner open side of bottom shell; whereas the light emitter emits invisible infrared, and the image sensor is used to sense infrared. Accordingly, the invisible infrared emitted by the light emitter prevents human eyes from damage by high energetic laser beam and makes mouse more sensitive to gain the functions of protecting eyes, precise position, and steady cursor.
Claims2
A structure of “Invisible Infrared Laser Mouse” mainly consists of a upper shell, a lower shell and a microprocessor, and characterized by:
- An opening set up at the bottom surface of bottom shell with light emitter and image sensor at inner side of the opening, the direction of light emitter arranged in a 45 degree slant angle, and a lens fixed at the lower of the image sensor in a slant angle from 5 to 10 degree designation. The light emitter projects light out of the opening, the light beam projected by the light emitter is invisible infrared, while the light sensor was used to sense the invisible infrared which is emitted by the light emitter.
The device of “Invisible Infrared Laser Mouse” of claim 2, wherein infrared invisible light is a kind of infrared laser light.
