Abstract
A keyboard with illuminating architecture includes a keyboard portion and a substrate carrying the keyboard portion, wherein the keyboard portion includes a plurality of pressing elements for receiving a pressing force from the user and inter-dependent mechanisms respectively under a force receiving surface of each pressing element for providing a moving stroke of the pressing element following the force direction, and the substrate has an assembling portion for assembling with the other end of the inter-dependent mechanism. Moreover, the surface of the substrate has at least one light guiding groove, which forms a light channel for transmitting light, and at least one inner sidewall of the light guiding groove is a light reflecting surface, so that the light in the light guiding groove is reflected by the light reflecting surface to the keyboard portion, thereby providing the pressing elements the brightness, and reducing whole keyboard thickness and thinning.
