To provide a thick film paste printing machine in which a defect, e.g. a pinhole (bubble), is not generated in the paste by avoiding a problem that the productivity lowers due to prolongation of the time required for printing work.
A first and a second scrapers 4 and 5 are provided in a scraper structure such that vertical movement thereof can be regulated independently by a first and a second scraper driving mechanisms 14 and 15, respectively. The gap between the front edge of the scraper and a screen 1 is thereby set smaller for the post-stage scraper 5 than for the prestage scraper 4 in the advancing direction at the time of paste coating and thereby the pushing amount of post-stage is larger than that of the prestage. Since the first and second scrapers 4 and 5 are fixed to the same driving section 3 together with the first and second scraper driving mechanisms 14 and 15, they advance simultaneously in the horizontal direction at the time of paste coating.
