Method and apparatus for identifying objects using compound signal and a

A method for switching an optical connector having paired optical connectors, having pins engaged with engaging holes of the optical connectors, which involves a connector disposing step of disposing the switching optical connector parallel to the separating optical connector, a pin forward moving step of moving the pins engaged with both the reconnecting and separating optical connectors each other to the reconnecting optical connector side, then a connecting switching step of relatively moving the reconnecting optical connector, the separating optical connector and the switching optical connector and the front end faces thereof, and finally pin backward moving step of moving the pins of the reconnecting optical connector side to the switching optical connector side. Thus, the method and an apparatus for switching an optical connector can momentarily switch to connect optical transmission units with optical connectors without depending upon a worker's skill as well as to mechanize or automate the replacing work.
