Abstract: An outer display is provided in an area exposed to the outside, of a first movable part in a closed condition where the first and second movable parts are opposed to each other. An outer operation section is provided in an area other than the exposed area of the first and second movable parts whichever comes behind the outer display in a closed condition where the first and second movable parts are opposed to each other. The operator can enter predetermined information on a predetermined display content displayed on the outer display. Even in a condition where the first and second movable parts fold closed, the operator can enter predetermined information from the outer operation section while watching the outer display, which enhances the operability.
