Abstract
A transparent operation plate is disposed on the operation panel of an input device in correspondence with tone information to be input. A pair of touch contacts are formed exposed on the surface of each transparent operation plate. A liquid crystal display element is disposed immediately below the transparent operation plate. The liquid crystal element displays characters representing the tone information, as well as the information input operation condition. This display can be visually confirmed through the transparent operation plate.
