An air suction section (,) is lifted until its front end contacts with the screen mask (,), the air suction mechanism (,) starts cleaning by sucking air from the openings (,) in the screen mask (,). An inspecting camera (,) is used to observe the cream solder (,) remaining in the openings (,) after cleaning, and the air suction flow rate is controlled according to the results thereof to effect cleaning again.
