ABSTRACT:
An optical communication unit includes a light emitting-receiving element provided in such a manner that an optical axis thereof is set perpendicular to an electric circuit substrate, a reflecting plate for changing a direction of the optical axis, and a filter. The reflecting plate is provide outside the filter so as to be freely rotatable around one end of the reflecting plate. Since the reflecting plate is arranged so as to be rotated to a position where the filter is covered when optical communication is not carried out, the filter can be protected from being scratched or accumulating dust, and the unit can be made thinner. On the other hand, when optical communication is carried out, by rotating the reflecting plate, the communication direction can be set as desired.
