PURPOSE:To easily form a mask corresponding to a brimmed and a brimless pictures by moving a mask of width direction corresponding to the width direction of a printing paper and forming an auxiliary mask which can freely move on the upper surface of the mask. CONSTITUTION:Right and left guide blocks 42 are moved corresponding to the dimension of the width direction of the printing paper 10 by the rotation of axes 46 and 50 having inverse screws on both ends and the masks of width direction 84 and 86 mounted on the blocks 42, the auxiliary masks of width direction 85 and 87 on the masks 84 and 86, which are located a little nearer to a center side than the mask 64, the mask 82 of length direction and the auxiliary mask 152 of length direction form the printing frame for the printing paper 10. As for the brimless picture, by moving the mask 82 and the block 88 in a left direction, the mask 152 is sheltered upward through a pin 138 and a gear 136 and the masks 85 and 87 are respectively sheltered outside by the rotation of a link 120. Thus, the mask corresponding to the brimmed and brimless pictures can be easily formed.
