Abstract

PURPOSE: To readily determine reference line by so projecting the image of a permeation type original as to overlap with the layout image of layout specifying paper, measuring the angle formed by the reference line of the layout specifying paper and original detaining part and drawing the reference line for halftone photography on the non-image part or other of the original.
CONSTITUTION: A transparent base plate 4 and a transparent base plate 3 provided with a permeation type original 1 and auxiliary piece 2 are loaded to an original stand 5 with the innermost straight light part 6 as a guide. The original image of the original 1 is then projected to the layout specifying paper 16 on a projecting plate 9. The position of the paper 16 is so adjusted that the layout image of the specifying paper 1 and the proiected image overlap, thence the paper 16 is fixed to the projecting plate 9. When in this state a cursor 10 is positioned so as to become parallel and rectangular to the base line by the cruciform marks 17, 18 provided to the specifying paper 1, the angle assumed by the base line of the paper 1 and the straight line part 6 forming the detaining part of the original 1 is measured by a scale plate 14. Next, when the base line 19 is drawn to the auxiliary piece forming the non-image part of the original 1 according to the measured angle, the base line for mounting the original 1 to a halftone photography scanner is readily determined.
