  • Electronic device provided with an input means
    Publication number: 20020042853
    Abstract: In an electronic device, its main unit has a data processing function and has a first and a second input means. The first input means is coupled to the main unit so as to be movable relative thereto between a first position in which the first input means overlaps with the main unit and a second position in which the first input means protrudes from the main unit. The first input means permits input operation in both of the first and second positions. The second input means is arranged in the main unit so as not to be movable relative thereto. The second input means is hidden by the first input means when the first input means is in the first position, and is exposed when the first input means is in the second position. The second input means permits input operation when it is exposed. The first input means is interchangeable with a third input means.
