<p>A keyboard assembly ( 20 ) has a light guide ( 23, 31, 33 ) and a supporting structure ( 23, 33 ) arranged to provide an illuminated and integrated keyboard assembly ( 20 ). A light guide ( 23, 31, 33 ) provides an integrated supporting, protecting and illuminating structure for keyboard assemblies ( 20 ). The keyboard assembly ( 20 ) has a layer of rigid material ( 31 ) which separates the elastic layer ( 21 ) from the printed wired board ( 9 ) located under the rigid layer ( 31 ). The layers are bonded together. The protection rib ( 33 ) is part of the combination of the elastic layer ( 21 ) and rigid layer ( 31 ) which is supported against the printed wired board ( 9 ) by the rigid layer ( 31 ). The combined structure of the light guide and supporting frame forms an integrated structure ( 23, 31, 33 ) which illuminates an array of keys ( 22 ), supports the keyboard assembly ( 20 ) and protects the keys ( 22 ) and key tops 25 from mechanical stress.</p> |
