Portable terminal with optical transmitting/receiving portion

A portable terminal having optical transceivers is provided to use the optical transceivers as units for maintaining communication lines of circuit devices between housings, thereby enabling transmission of high-speed and high-capacity information. The first optical transmitter(211a) is mounted on the first housing(101). The first optical receiver(213a) confronts the first optical transmitter by being mounted on the second housing. The second optical receiver(213b) is mounted on the first housing. The second optical transmitter(211b) confronts the second optical receiver by being mounted on the second housing. The first optical receiver, the first optical transmitter, the second optical receiver, and the second optical transmitter are disposed along a hinge shaft(A1). The first optical transmitter and the second optical receiver are individually mounted on both sides of a circuit board extended from the first housing.
