Abstract

PURPOSE:To attain automatic acquisition and tracing of communication party by applying drive control to a tracking mirror and a rotary table with mounting it thereupon in matching with position information of the communication opposite party obtained from the tracking mirror and the optical sensor. CONSTITUTION:The tracking mirror 5 freely elevated is arranged oppositely in a horizontal direction to a common part between an optical output of a transmission optical system 3 and an optical incidence side of a reception optical system 4 and the tracking mirror 5 is equipped onto the rotary table 6. Then 1st and 2nd drive control means 5B, 6B applying drive control to the rotary table 6 and the tracking mirror 5 in matching with the behavior of the opposite party are provided and a control variable arithmetic section 8 is provided between the 1st and 2nd drive control means 5B, 6B and the reception photoelectric conversion section 2. Thus, the optical communication line in following to the movement of the opposite party automatically is easily formed.
