<P>PROBLEM TO BE SOLVED: To provide a keyboard with a light source for illumination that can effectively illuminate key tops with an electrically-conductive layer kept invisible from the front side of the key tops in a configuration where translucent key tops are poked out from arrangement holes in opaque front cases arranged in front of a print board with space between the front cases and are supported by transparent rubber sheets that are arranged between the print board and the front cases, a moving contact is positioned on the rubber sheet that is just beneath a key top and corresponds to that key top, and the light source is fixed on the print board. <P>SOLUTION: An electrically-conductive layer 702 is attached to the surface of a moving point white layer 701 with a moving point 70 positioned on the face of a rubber sheet 50 so that the electrically-conductive layer 702 cannot be seen from a key top 40 side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
