Abstract
To positively compress ejected master plates at a high compression ratio without requiting any complex structure, a piston member for compressing ejected master plates is placed in an ejected master plate box for receiving ejected master plates from an ejected master plate receiving inlet so as to be moveable between a first position and a second position, and the movement of the piston member toward the second position causes the stencil master plates to be compressed against an end wall of the ejected master plate box. The piston member is provided with a motor-driven suction fan which draws air out of the ejected master plate box to move the piston member toward the second position, and is biased toward the first position by a spring member.
