A printing machine 10 that reciprocates a squeegee unit 20 including a printing squeegee 24 in one direction on an upper surface of a mask 13 where a printed-circuit board A is disposed on a lower side thereof to move cream solder B thereby printing the cream solder B on the circuit board A, includes a scraping squeegee 31 and a scooping squeegee 33. The scraping squeegee 31 and the scooping squeegee 33 reciprocate together with the squeegee unit 20 in a direction of a printing operation and can relatively move toward and away from each other in the direction of the printing operation, in order to be capable of scooping the cream solder B on the upper surface of the mask 13. A covering portion 32, formed of a nonwoven fabric having recesses and protrusions, is attached to the scraping squeegee 31. |
