Abstract

PURPOSE:To prevent light signals from impinging on eyes by a method wherein a light emitting element outputs light signals only when an optical fiber is connected to an optical output connector. CONSTITUTION:Electrically insulated conductors 6 and 7 are mounted on an output connector 5, and when a terminal 4 fixed to an optical fiber used for taking out light signals is connected to an optical connector 5, the conductors 6 and 7 become electrically conductive, and in result optical fiber connection detection signals 8 and 9 are outputted. On the other hand, a drive circuit 2 outputs a drive signal 3 which drives a light emitting element 1 that converts the inputted electrical signals into optical signals only when the optical fiber connection detection signals 8 and 9 are inputted.
