摘要： A key structure with a scissors-type connecting member is provided. The scissors-type connecting member includes a first frame and a second frame. The first frame has a bulge. The second frame has a recess. The height of the bulge is smaller than the length of the recess entrance. The length of the recess bottom surface is greater than the length of the recess entrance. After the bulge of the first frame is introduced into the recess of the second frame, since the length of the recess bottom surface is greater than the length of the recess entrance, the possibility of detaching the bulge from the recess during the operation of the scissors-type connecting member will be minimized.

摘要： An illuminated keyboard of a notebook computer includes a base, a base cover, a key module and a light-guiding and supporting plate. The base is sheltered by the base cover. The light-guiding and supporting plate is disposed under a base cover opening of the base cover and fixed on the base cover. Since the key module is supported on the light-guiding and supporting plate and exposed outside the base cover opening, the thickness of the illuminated keyboard is not increased, and it is not necessary to shorten the travelling distance of the key module.
