<p>PURPOSE:To obtain a thin and simple constitution ensuring a visible and bright display by disposing on the surface of a light emitting display body a lower transparent electrode group composing a key matrix and thereon a transparent member having an upper transparent electrode group on the lower surface away from a space. CONSTITUTION:An opaque electrode group 2 composing the lower contact point of the key matrix is installed on the upper surface of the light emitting display body 1 such as a cathode ray tube and a plasma display. The transparent member 3, where the upper transparent electrode group 4 composing the upper contact point of the key matrix is installed on the lower surface spaced out by sandwiching spacer 6 in between, is installed on the electrode group 2. When the transparent member 3 is depressed with fingers, etc., the upper transparent electrode at the point comes into contact with the lower one to close one point of the key matrix, and the operation is shifted to a key input.</p> |
