A luminous keyboard includes a lateral-emitting type illumination element, a light guide panel, a sensing circuit pattern and plural keys. The lateral-emitting type illumination element is used for providing a light beam to the light guide panel, so that the light beam is diffused to the whole light guide panel. The light guide panel has plural light-guiding dots for collecting and scattering the light beam. The portion of the light beam scattered upwardly by the light-guiding dots is projected to the plural keys. The sensing circuit pattern is formed within the light guide panel or formed on a surface of the light guide panel. When any key is moved toward the sensing circuit pattern, the sensing circuit pattern generates a corresponding non-contact key signal. |
