PURPOSE:To realize a rational enlarging and transferring method by lighting up a fixed original design drawing, by reflecting its reflected light by a mirror by way of a lens, and then by enlarging and projecting it upon a design paper table. CONSTITUTION:Firstly, an original design drawing is fixed to design frame 6 and lamp 7 is turned on. Then, light from the lamp is reflected on the original design drawing and further reflected by mirror 9 by way of lens box 8 to enlarge and project the original design drawing upon design paper table 21. For this purpose, design paper is fixed on design paper table 21 and the height of case 5 and the focus of the lens are adjusted to project the clear design drawing pattern on the design paper to a desired size. At this time, the magnification of image enlargement can be adjusted by replacing the lens through the opening part in the center of the flank of case 5. |
