Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a screen coating device and a device therefor by which the occurrence of defective articles due to a difference in density of a coating film caused by uneven wear of a squeegee and a trap of foreign matter is restrained and stroke stop time due to frequent replacement and polishing of the squeegee can be reduced. SOLUTION: In the direction perpendicular to the direction in which a squeegee scrapes a screen, or in the direction perpendicular to the advancing direction of a support body to be coated when a cylindrical screen print is used or when a flat screen print is moved at the same velocity as that of the support body to be coated, a squeegee is slid. The amplitude of sliding is preferably 3-50 mm and sliding velocity 1-100 mm/sec.
