摘要： To produce an ultrathin and easily assembled optical pointing device by reducing the number of components, an optical pointing device (10) of the present invention includes: a light source (2) for emitting light to an object (1); a light guide (6) for propagating therethrough light scattered by the object (1), the light guide including an image forming section (4) for forming an image with use of the light scattered by the object (1); and an image capturing section (7) for capturing the image with the light that has been scattered by the object (1) and that has exited the light guide (6). The light guide (6) guides a light beam (L) from the object via no air through an optical path extending from (i) a position where the light beam (L) enters the light guide to (ii) a position where the light beam exits the light guide (6).

摘要： An inclined plane (13) of a prism (12) serving as a light-direction changing element transmits and refracts light emitted from an LED light source (16) so that a contact surface (11) is illuminated with the light thus refracted. The light is diffusely-reflected from an object which is in contact with the contact surface (11). A part of the light thus diffusely-reflected is transmitted through the prism (12). A light path of the part of the light is changed by the inclined plane (13) so that a lens (14) serving as an image-forming element receives the part of the light. The lens 14 forms an image on the basis of the part of the light thus received. An image-capturing element (15) captures the image thus formed as image data. The image data obtained by the image-capturing element (15) is subjected to image processing, so that a change in the contact surface (11) is extracted. On the basis of the change thus extracted, an amount of movement of the object and a direction of the movement can be obtained. With the arrangement, it is possible to realize an optical pointing device having a small and thin body.
