OPTICAL POINTING DEVICE AND ELECTRONIC EQUIPMENT PROVIDED WITH THE SAME, AND LIGHT-GUIDE AND LIGHT-GUIDING METHOD

摘要

In order to reduce the number of components in the optical pointing device, and the number of steps for assembling, bonding, etc. the components, a light guide (24) according to the present invention for use in an optical pointing device (30) is configured to include a redirecting element (12) for receiving light from a touch surface (11) and reflecting the light so as to guide the light into a horizontal direction, and an image forming section (14) for receiving the reflected light and reflecting the reflected light to an opposite direction backward to the horizontal direction, so as to form an image of the light, the light guide (24) outputting the image of the light from a light output section.
