PROBLEM TO BE SOLVED: To solve failure due to high speed operation of a loop type conveyer line. SOLUTION: When a conveyed body 2 conveyed at a low speed on the loop type conveyer line 1 is caught by a catching means 19 and a belt 17 is moved, the conveyed body 2 is conveyed at a high speed. When the belt 17 is stopped and the catching means 19 is released at the time when the conveyed body 2 is conveyed to a predetermined position at the high speed, the conveyed body 2 is conveyed again at the low speed on the loop type conveyer line 1. As a result, the loop type conveyer line 1 operates at the low speed as it is, so that a failure due to the high speed operation, namely a failure due to vibration or noise during driving and a failure of fine acceleration operation, can be solved.
