Abstract: The main body section and the cover section, those of which are combined with the coupling section so that the electronic device can pivot, constitute the present invention. There is an input key section is provided in the opposed surface of the main body section meeting the cover section when the device is folded. There is the main display section provided in the opposing surface of the cover section meeting the main body section when the device is folded. Because of this, the electronic device can be used easier as a mobile phone. Furthermore, the electronic device also can be used easier as a still camera because the device can be used as a still camera immediately whenever the user wants to, even when the electronic device is in stand-by mode of mobile phone mode.

Abstract: Music data is easily and positively produced from a melody the user imagined to himself/herself, without the need of musical expertise. Accepted are an input of a melody voice the user is singing to himself/herself and a key depression corresponding to a rhythm of the melody voice to be inputted. Depending upon a timing of the accepted key depression, voice pitch and note value are extracted from the melody voice. The produced music data is format-changed into a file for outputting at a terminal unit, and then sent toward the terminal unit.
