摘要
PROBLEM TO BE SOLVED: To shorten a printing time for a photograph and further, to make an image sharp and an experiment in photosensing efficient by constituting photosensitive material substrate matter, in such a manner that a substrate plate notched to provide a large hole and a receptive plate are laid over the other. ;SOLUTION: The substrate plate 1 is notched to provide the circular large hole 11 at almost the center of the plate 1. As an original sheet 2, a tracing paper having a capital latter of A formed at almost the center with magic ink, as an image 21 is used. The original sheet 2 and a sensitized paper 3 are laid over the other, in a state where they are closely stuck to each other, to be a laminate. The laminate and the substrate plate are lid over the other and stuck, in such a manner that the image 21 formed on the original sheet 2 of the laminate is arranged to receive irradiating light at the central part of the large hole 11 provided by notching the substrate plate 1. Further, a holding body constituted in such a manner that the rear surface of the sensitized paper 3 and the original sheet 2, in the laminate are closely stuck to the receptive plate 4 and the substrate plate 1 respectively, to lay them one on top of another in order is held by four gem clips 5 in the vicinities of both end parts of the long sides of the holding body.;COPYRIGHT: (C)1998,JPO
