Portable electronic apparatus
First Claim
1. A portable electronic apparatus comprising:
- a first unit;
a second unit rotatably connected with the first unit through a hinge portion;
a cylindrical joint member arranged to be coaxial with a rotation center axis of the hinge portion and rotatably supporting the second unit with respect to the first unit, the joint member having one end portion projecting into the first unit and another end portion projecting into the second unit, the joint member defining a communication path which extends to be coaxial with the rotation center axis of the hinge portion and has one end communicating with an inner space of the first unit and another end communicating with an inner space of the second unit;
a light emission element provided in the first unit for emitting an optical signal to the second unit through the communication path; and
a light receive element arranged in the second unit so as to face the light emission element through the communication path for receiving the optical signal from the light emission element.

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.
