<p>Provided are mobile electronic devices that have function manipulability that conforms more closely to the actual manner of use by users. A mobile electronic device (1) is provided with a case, a rotary dial (41) that is installed rotatably on said case, and a processing unit (70) that transitions to an indeterminate function state to await the completion of said rotation, when the beginning of rotation of the rotary dial (41) is detected. When it is judged that said rotation is complete in said indeterminate function state, the processing unit (70) cancels said indeterminate function state and starts the corresponding function based on said rotation. When a prescribed event occurs in said indeterminate function state, a prescribed interrupt processing that corresponds to said prescribed event is performed prior to the start of the prescribed function that is based on said rotation.</p> |
