PROBLEM TO BE SOLVED: To surely form a liquid drop layer within one liquid drop layer in the manufacture of an asymmetrical laminated preparation by ejecting liquid drops using an ejection head such as an inkjet head. SOLUTION: An ideal impact position established beforehand of a liquid drop on a substrate is held in a memory. An actual impact position of a liquid drop supplied onto the substrate is detected by image processing. The difference between the detected impact position and the ideal impact position of the liquid drop is calculated and is held as an impact position correction datum and the operating command is corrected according to the impact position correction datum to generate a new operating command.
