PROBLEM TO BE SOLVED: To efficiently perform an aligning work of optical components to align two connection ports concentrically without an aligning work to eliminate an axial disalignment at every rotation of a C-axis. SOLUTION: A positional relationship value expressing the deviation of an input port with respect to the rotation center of the C-axis is derived by a calculation by using two sets of X-Y coordinate values after the rotation of the C-axis, the positional correction is performed with the positional relationship value when the C-axis is rotated, and the axial alignment of an output port is performed by rotating the output port around the center of the input port.
