Electronic apparatus provided with a rotating-operation member and the rotating-operation member

An electronic apparatus provided with a plurality of rotating-operation members, in which respective disk sections of the plurality of rotating-operation members are arranged to be at least partially overlapped, to thereby enable it to achieve space-saving. As the electronic apparatus capable of achieving the space-saving, there is included a film camera, a digital camera, and a video camera, that is an image pick-up device. Rotational axes extended from respective disk sections may be parallel coaxial or parallel non-coaxial, or may be inclined to each other. Additionally, in order to prevent surfaces from being scratched or damaged by mutual contact between the disk sections, a protrusion may be provided.
