ABSTRACT:
In a screen printing machine, its printing-plate discharge unit is provided with: a pair of printing-plate discharge rollers which may approach to a peripheral surface of a plate cylinder and may also draw therefrom; and a waste-paper container for receiving a waste printing plate having been peeled from the peripheral surface of the plate cylinder. In the waste-paper container is provided a waste printing-plate compression plate which is vertically movable in the waste-paper container. The compression plate is moved up and down in the waste-paper container by means of an operation means which is provided in a position outside the waste-paper container. The compression plate compresses the waste printing plate in the waste-paper container when moved downward therein.
