いる。2. Description of the Related Art As a conventional separating device for a diazo copying machine, for example, one disclosed in Japanese Utility Model Publication No. 43-27426 is known. This one has a document suction plate and a photosensitive paper suction plate which face each other, and when the superposed document and photosensitive paper are passed between the document suction plate and the photosensitive paper suction plate, they are sucked and separated by the suction plate side. It is supposed to be done. Many of the originals used in the above-described diazo copying machine are not flat, for example, those having curls on the front side (commonly called face curls) and curls on the back side (commonly called back curls). When such a non-flat original is passed through the separating device having the above-described configuration, there is a problem that separation is uncertain because no measures are taken against curling. For the purpose of eliminating such a problem, for example, the one described in Japanese Utility Model Publication No. 63-4215, which is provided with a pressing force assisting member for pressing the superposed original and the photosensitive paper against the original suction plate side near the entrance of the separating device, A method disclosed in Japanese Utility Model Publication No. 44-8865 is proposed in which the document suction plate side is arranged upstream of the photosensitive paper suction side in the paper conveying direction so that the document and the photosensitive paper are easily sucked to the document suction side.

題点があった。However, in such a conventional separation device for a diazo copying machine, the original and the photosensitive paper are simply pressed against the original suction plate side, or the original suction side from the photosensitive paper suction side. Since it has a structure in which it is also arranged on the upstream side in the paper conveyance direction, it has some effect on the separation failure due to face curl, but cannot sufficiently cope with the separation failure due to back curl. was there.

Since this is an example in which the feed roller 36 and the feed roller 36 are provided, description of other configurations and operations will be omitted. 8 and 9,
A feed roller 36 is arranged near the paper entrance on the side of the photosensitive paper suction plate 22 and a feed roller 36 near the paper entrance on the side of the document suction plate 18.
A driven roller 34 is arranged at a position substantially opposite to. The feed roller 36 is rotationally driven by a driving means (not shown),
The driven roller 34 is biased toward the feed roller 36 by the biasing member 35. Further, as shown in FIG. 9, the tangent line L of the nip formed by the feed roller 36 and the driven roller 34 is set to be biased toward the document suction plate 18 side on the downstream side in the sheet passing direction. Therefore, the driven roller 34, the biasing member 35, and the feed roller 36
Is a biasing means for biasing the document 1 and the photosensitive paper 2 to the document suction plate 18 side in the vicinity of the sheet entrance between the document suction plate 18 and the photosensitive paper suction plate 22, and the biasing means is the document 1 And a member that applies a conveying force to the photosensitive paper 2.
In this embodiment, the feed roller 36 and the driven roller 34 are arranged at positions substantially opposite to each other, but they may be arranged alternately as shown in FIG.
