description A control unit obtains a captured image of a reference workpiece by a second image capturing unit after a droplet ejected from a droplet ejecting head lands toward a reference mark formed on an upper surface of the reference workpiece, detects a positional deviation amount of a position of the reference mark and a landing position of the droplet based on the captured image, and calculates the correction amounts of the relative positions of a workpiece table and a droplet ejecting head based on the positional deviation amount.
