Abstract
In an optical transmitting and receiving apparatus. an light transmitting and receiving unit includes a light emitting element, a light transmitting lens, a light receiving lens, and a photosensitive element. The light emitting element outputs light. The light outputted from the light emitting element passes through the light transmitting lens before leaving the light transmitting and receiving unit as outgoing light. The light receiving lens concentrates incoming light on the photosensitive element. A first support member is operative for supporting the light transmitting and receiving unit, and for allowing the light transmitting and receiving unit to rotate about a first axis. A first rotary mechanism connected to the light transmitting and receiving unit and the first support member is operative for rotating the light transmitting and receiving unit about the first axis. A second support member is operative for supporting the light transmitting and receiving unit on a cantilever basis, and for allowing the light transmitting and receiving unit to rotate about a second axis perpendicular to the first axis. A second rotary mechanism connected to the light transmitting and receiving unit and the second support member is operative for rotating the light transmitting and receiving unit about the second axis.
