Abstract: An electronic device includes a pad which can detect an operating coordinate position by a touch operation, and a single push-switch provided under the pad. A touch operation to the pad at a given place allows a preliminary announcement of a function, and a further press-down of the pad being kept at the same position prompts the push-switch to work and determine the function preliminary announced. This structure allows excellent operability, and a single push-switch allows reducing the number of components of the operating section, so that the electronic device having these advantages is obtainable.
