PURPOSE: To judge the stopped position of a moving body even in the case where the skipping of engagement occurs between a driving rotary body and an indexing body by detecting a detected part through a detecting section when the moving body stops correctly at a prescribed reference stopping position.
CONSTITUTION: In the case where a base table 60 and an ascending body 80 stop at each fixed stopping position, and the detecting section 132 of a position detecting means 130 detects a detected part 131, and the detecting section 142 of the position detecting means detects a detected part 141, it is judged that the base table 60 and the ascending body 80 stop correctly at each fixed stopping position. At this time, a control signal is output from a driving control means 200 to a taking in and out body 90, which thereby delivers and receives an article to/from a receiving shelf 10. On the other hand, in the case where the detecting section 132 of the position detecting means 130 does not detect the detected part 131, the base table 60 is judged not to be correctly at the fixed stopping position, and in the case where the detecting section 142 of the position detecting means does not detect the detected part 141, the ascending body 80 is judged not to be correctly at the fixed position, and the stopping position is therefore corrected.
