摘要： A scanning light contact duplicating apparatus 10 is described which includes an exposure frame 28 having a front and rear edge between which extends a backing plate 41 that is used for supporting an original sheet 56 such as a negative transparency to be copied, together with a photosensitive sheet 54 in contact with it. A transparent cover 42 is connected to the exposure frame 28. Provision is also made for pressing the transparent cover 42 toward the backing plate 41 to force the original sheet 56 (negative) into close contact with the copy sheet (photosensitive sheet 54). An elongated light 138, usually a gas or vapor lamp, is positioned parallel to the front edge of the exposure frame 28. The light 138 is supported for rectilinear movement toward the rear of the exposure frame 28 and parallel to the plane of the exposure frame 28. A collimator 146 is preferably provided between the light 138 and the exposure frame 28. The collimator 146 has a honeycomb array of parallel open-ended cells, each of the cells having walls perpendicular to the exposure frame 28.

摘要： The invention provides a contact photocopying apparatus 10 which includes a supporting frame 12 and a cover 14 adapted to be raised and lowered with respect to the supporting frame 12. A flexible sealing sheet 30 is bonded at its edges to the supporting frame 12. A cushion 34 is secured beneath the sealing sheet 30. The cushion 34 is formed from elastic material and has a smoothly contoured semi-cylindrical top surface. A firm backing plate 40 is connected to the lower surface of the cushion 34. The flexible sealing sheet 30 has a free edge portion 52 which extends beyond the edges of the cushion sheet 34. A flexible reinforcing strip or band 50 is provided which has one portion connected to the free edge 52 of the sealing sheet 30 and another portion connected to the edge of the cushion 34 to permit flexing of the free edge portion 52 of the sealing sheet 30 with respect to the cushion 34. The flexible sealing sheet 30 extends across an opening 40a in the backing plate 40 to define a flexible diaphragm 30a. A vacuum line 56 is connected to the center of the diaphragm 30a and is suppored by it for limited movement. A stop member 58 is operatively associated between the vacuum line 56 and the backing plate 40 to limit the motion of the vacuum line 56 toward the cover 14 when a vacuum is created in the chamber 24. A sealing strip 60 is provided around the edge of the supporting frame 12 having at least one inclined cantilevered sealing flange 62 which slopes outwardly and is adapted during operation to flex outwardly and downwardly when engaged by the cover 14 to seal the edge of the vacuum chamber 24.
