PURPOSE: To enable printing on several kinds of glasses fitted with a handle and differing in diameter to be performed through using a single kind of screen frame without need for replacing the screen frame on the basis of the diameter of the glasses, by enabling the spacing between parts of a frame.

CONSTITUTION: A fixed frame made of a metal such as stainless steel is provided with a rectangular opening part at a central part thereof, and with slots 4 in both side walls 7 thereof. The fixed frame 1 is supported by L-shaped fittings which serve also as electrodes. A movable part 2 which is U-shaped in vertical section and provided with a multiplicity of tapped holes 5 in both side pieces thereof is fitted to the fixed frame 1 by bolts 3. The movable part 2 can be fastened to the fixed frame 1 by fitting the movable art 2 in the opening part of the frame 1 and inserting the bolds 3 into the tapped holes 5 at desired positions of the movable art through the slots 4 provided in the side walls 7 of the frame 1. When the slots 4 in the fixed frame are enlarged, the width l of the screen frame can be controlled in a stepless manner.
