<p>A system for indexing an attachment, wherein: a target indexing positional angle of the attachment is instructed by an indexing positional angle instructing means (1); the current positional angle is detected by a positional angle detecting means (2) the target indexing positional angle and the current positional angle are compared with each other by an angle comparing means (3); an indexing rotational direction of the attachment is determined on the basis of the comparison result by an indexing rotational direction determining means (4); an indexing rotational angle of the attachment is calculated from the angle comparison result and the indexing rotational direction by an indexing rotational angle calculating means (5); and the attachment is indexingly rotated on the basis of the determined indexing rotational direction and the calculated indexing rotational angle.</p> |
