<p>PURPOSE: To provide a noncontact pointing device with high reliability and high durability adapting to space saving operation. CONSTITUTION: A movable body 20 which is displaced by being weighted in a two-dimensional direction consists of a cylindrical movable part 26 which is displaced by artificial operation and a fixed part 27 for fitting the movable body 26 to an equipment 23 such as a computer. A tilt sensor consisting integrally of a light emitting element 21, a light receiving element 22 which receives an image of light from the light emitting element 21 moving associatively with the displacement of the movable body 20, and a lens 28 for image formation is put in the movable part 26 and mounted on the fixed part 27, and the surface of the movable part 26 which faces the light receiving element 22 is processed into a reflecting surface 36.</p> |
