PURPOSE:To securely bring a photographic negative plate and a photosensitive plate into contact with each other speedily by providing a holding member which presses the outer peripheries of many disks against a sheet member by the weight of each disk and moves the many disk plates on the sheet member movably along a plane holding plate. CONSTITUTION:A rubber roller 17 slides while pressed against the plane holding plate 1, so the photosensitive plate 4 and photographic negative plate 47 are pressed against the plane holding plate 1 to push air out of between a film body 15 and the plane holding plate 1. Then, a vacuum pump is put in operation to suck air between the plane holding plate 1 and film body 15. At this time when a rod 27 is moved in parallel from one side of the film body 15 to the other side and then the film body 15 is pressed with the uniform pressing force based upon the weight of respective ring plates 25 within a range where the respective ring plates 25 pass. Consequently, the air between the film body 15 and plane holding plate 1 is securely expelled, so the photosensitive plate 46 and photographic negative plate 47 contact the plane holding plate 1. |
