Abstract

PROBLEM TO BE SOLVED: To easily mount a metal mask on a printing plate frame by fixing the mask to the frame by a metal mask pressing pressure plate in the state that the periphery of the mask is bent. SOLUTION: A metal mask 3 is so disposed at the metal mask supporting part 7 of a printing plate frame 2 as to support the periphery of the mask 3. The engaging piece 14 of a metal mask pressing pressure plate 4 is engaged with the engaging hole 13 of the frame 2. The movable end of the plate 4 is so urged as to be disposed in the frame 2, and the engaging piece 15 of a fixture 17 is engaged with the engaging hole 15 of the frame 2. As a result, the periphery of the mask 3 becomes the state to be urged and fixed by the part 7 of the frame 2 and the urging support part 12 of the plate 4. Accordingly, the mask 3 becomes a cover state bent at the periphery by the oblique surface of the part 7 to become the state that tensile strength is given to the mask 3.
