Abstract

PURPOSE: To put a reference line readily and accurately on the original in parallel with the base line of layout image by projecting the transmission type original on the layout image on layout assigment paper with a projector, moving the layout image until both images align, removing the original and superposing on the layout image.
CONSTITUTION: When there is no non-image portion for putting a reference line in the transmission type original 1, an auxiliary piece 2 is mounted and is fixed to a transparent base plate 3. The transparent base plate 3 is mounted in close contact with the longest linear part 6 of the original frame 5 of the projector and the image of the original is projected onto the layout assignment paper 13 having been put with layout image on a projection plate 9. Sinzes of both images are so adjusted as to become equal and both images are aligned by moving the layout image, thence the layout assignment paper 13 is fixed. The transparent base plate 3 is removed from the original frame 5 and is so placed on the projection plate 9 that the side which had made close contact with the longest linear part 6 becomes parallel or rectangular to the opposing mark 14 or 15 of the layout assignment paper 13. Next, a scribing bar 10 is moved in parallel to or at a right angle to the longest linear part 6, whereby a linear delineation line 16 is put on the non- image part of the transmission type original or the auxiliary piece 2.
