To prevent a positional displacement of a screen mask in accordance with movement of a squeegee, a single squeegee device and a printing agent feeding device moves in synchronism with each other along a guide member. A squeegee elevated/lowered at a predetermined timing is mounted at a lower end of the squeegee device. A printing agent scraping device is mounted at a lower end of said printing agent feeding device. The printing agent scraping device is structured by a scraping frame which is elevated and lowered at a predetermined timing and moves in a direction in contact with or away from the squeegee and a printing agent extruding plate which is retracted/projected at a predetermined timing within the scraping frame.
