摘要: A key switch structure includes a key top, a membrane sheet, a plate member, and a light source. The key top on which an unpainted character portion that is permeable to light is formed. The membrane sheet comprises a contact portion and is permeable to light. The plate member is disposed below the membrane sheet and is permeable to light. The light source is disposed below the plate member. The unpainted character portion of the key top is lighted via the plate member and the membrane sheet by causing the light source to emit light.

摘要: A keyboard apparatus has a base component arranged under key switches. The base component has an embossed portion. A cooling material is filled into the embossed portion. The embossed portion may be formed continuously between the key switches along the length of key rows over substantially the entire length from the left end to the right end of the rows. On the base component, a membrane sheet having contact point portions corresponding to the key switches may be arranged. The membrane sheet may have a heat dissipation hole at a part opposing the embossed portion.
