Abstract: The object of the present invention is to decrease the cost required for constructing the system and the tact time in production line. For achieving the above-mentioned object, according to the present invention, among a plurality of stations where adjustment or the like of the subject is carried out, the recognizing station, through which a pallet mounted with the subject is firstly passes, recognizes the positional deviations of the subject and stored them in a memory provided on said pallet. Next, an adjusting station reads out the above-mentioned positional deviations from the memory and added them to the predetermined standard positional information, thereby correcting the positional deviations of the subject.
