An illuminated keyboard includes at least one light-emitting element, a membrane switch circuit module, plural keys, a fixing plate, and a proximity sensor. The fixing plate includes plural openings, plural joining regions, and plural fixing regions. The plural fixing regions are arranged between the plural openings for fixing plural elastic elements of the plural keys. The proximity sensor includes an induction antenna circuit. The induction antenna circuit is formed on the plural joining regions or the plural fixing regions of the fixing plate for sensing whether an object enters a sensing range. |

1. An illuminated keyboard, comprising:
at least one light-emitting element providing a light beam to the illuminated keyboard; a membrane switch circuit module generating plural key switch signals; plural keys disposed over the membrane switch circuit module, wherein when one of the plural keys is depressed, the membrane switch circuit module generates the corresponding key switch signal, respectively, wherein each of the plural keys comprises an elastic element and a keycap connected with the elastic element; a fixing plate arranged between the membrane switch circuit module and the plural keys, wherein the fixing plate comprises:
plural openings disposed under each of the plural keycaps;plural fixing regions disposed under the plural keycaps, respectively, wherein each of the plural fixing regions is arranged between the plural openings under the corresponding keycap so as to fix the corresponding elastic element, wherein each of the plural fixing regions has a hole, and the corresponding elastic element is penetrable through the hole to push the membrane switch circuit module; andplural joining regions, wherein the openings between the plural fixing regions are connected with each other through the plural joining regions; and a proximity sensor sensing whether an object enters a sensing range, wherein the proximity sensor comprises an induction antenna circuit, and the induction antenna circuit is formed on the plural joining regions or the plural fixing regions of the fixing plate. |
