Abstract
A paper mask device in which the position of longitudinal masks can be changed without damaging a web of printing paper. When it is changed from the borderless printing to the printing with border, one ends of the longitudinal masks are moved inwardly toward each other by means of a first transfer unit while keeping the other ends overlapped on the edges of the printing paper. A second transfer unit then operates to move the other ends of the longitudinal masks inwardly to set the width of the print size. The longitudinal masks can be overlapped on both edges of the printing paper without damaging it.
