Electronic device provided with an input means

摘要

In an electronic device, its main unit has a data processing function and has a first (22) and a second input means (24). The first input means (22) 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 (21) and a second position in which the first input means protrudes from the main unit (21). The first input means permits input operation in both of the first and second positions. The second input means (24) 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.
