ABSTRACT:
A display unit is rotatably supported on an apparatus body of a portable electronic apparatus, by a hinge portion. The display unit has a hollow boss projecting into the apparatus body, and the boss is engaged with the apparatus body to be rotatable around the rotation center axis of the hinge portion. An inner hole in the boss communicates with the inside of the display unit and with the inside of the apparatus body, thereby forming a communication path coaxial with the rotation center axis. In the apparatus body, there is provided a light emission element for emitting image data to be transmitted to the display unit, in form of an optical signal into the communication path. In the display unit, there is provided a light receive element for receiving the optical signal from the light emission element through the communication path.
