| 摘要 |
The present invention is to avoid an occurrence of an suction error caused by a deviation with respect to a component of an suction nozzle, namely, an accident of a failure in capturing a component. A deviation amount is detected between a center of a component absorbed by an suction nozzle and an suction position of the suction nozzle. Also, a value in which this deviation amount is multiplied by a sensitivity coefficient is added as a positional correction at a next time of suction by the suction nozzle. Accordingly, when the suction nozzle absorbs the component at the next time, the suction nozzle normally absorbs the component at the position substantially corresponding to the center.
