Claim 11:
12. The device for aligning multicore fibers according to claim 11, wherein
the rotating portion rotates at least one of the pair of multicore fibers about the central axis such that a relative rotation angle between the pair of multicore fibers is smaller than P° after the camera captures the image of the side surfaces of each of the pair of multicore fibers in a state where the one multicore fiber and the other multicore fiber have the relationship of the specific relative rotation positions,
the camera captures a third set of images of the side surfaces of each of the pair of multicore fibers after the rotating portion rotates at least one of the pair of multicore fibers about the central axis such that a relative rotation angle between the pair of multicore fibers is smaller than P°,
the processor determines a similarity between the third set of images of the pair of multicore fibers, and
the rotating by the rotating portion after the state in which the relationship of the specific relative rotation positions is established, the the capturing of the third set of images, and the determining of the similarity between the third set of images are repeated until the determined similarity reaches the similarity in the predetermined range.
