されている。[Prior Art] Conventionally, stencil printing base paper is generally supplied as a cut sheet of paper cut to a predetermined size, and is manually set in a plate-making device each time a plate is made. In order to make it possible to repeatedly make many sheets of stencil printing paper without having to manually set the stencil printing paper into the stencil-making device each time the stencil is made, A stencil printing base paper roll is provided with a roll of stencil printing base paper wound around a core body and is replaceably attached to the stencil making machine so that the stencil printing base paper is automatically loaded into the printing device. The applicant and the present applicant have proposed a stencil-making device configured to be able to replaceably mount a stencil printing paper roll so that the stencil printing paper is supplied by the stencil printing paper roll. Patent application filed in 1982 by the same applicant
This method has already been proposed in No. 207216 (Japanese Unexamined Patent Publication No. 59-96983).

い穿孔を生じることがない。[Problem to be solved by the invention] The base paper for stencil printing that is thermally plate-made generally consists of a synthetic resin film such as a thin polyester film that is heat-sensitively perforated, and Japanese paper or Japanese paper pasted on one side of the synthetic resin film. It has a laminated structure of different sheets with a porous support such as a woven fabric, and unless the synthetic resin film is irradiated with light while the surface of the synthetic resin film and the original image surface of the original sheet are in close contact with each other, the synthetic resin film Correct perforation may not occur.

場合には正常な製版が行われない。このため孔版
印刷用原紙ロールは製版装置に対して常に正しい
軸線方向取付け姿勢にて取付けられなければなら
ず、さもないと正常な製版が行われない。 For this reason, if the base paper roll for stencil printing is installed in the opposite axial direction with respect to the plate-making device, that is, if it is installed with the left and right sides reversed, for example, the surface of the synthetic resin film will be the top surface and the original will be placed on top of it. The original sheet should be overlapped with the image side facing downward, but the surface of the porous support is facing upward, and the surface and the original image side face each other, so that the stencil printing base paper and the original sheet overlap. , In this case, normal plate making is not performed. For this reason, the base paper roll for stencil printing must always be attached to the plate-making device in the correct axial orientation, otherwise the plate-making will not be performed properly.

に装着されない。 As mentioned above, the axial lengths of the protruding shaft parts 53 and 54 of the stencil printing base paper roll 50 are different from each other, and the bearing devices 30 and 40 for receiving these protruding shaft parts are combined with the gate plates 34 and 44 as described above. As a result, when the base paper roll 50 for stencil printing is in the normal axial mounting position in which the protruding shaft portion 53 is received by the bearing device 30 and the protruding shaft portion 54 is received by the bearing device 40, the first As shown in FIG. 2, the stencil printing base paper roll 50 is correctly attached to the machine frame 1, but if the stencil printing base paper roll 50 is attached to the machine frame 1 with its axial orientation reversed. Then, in order for the protruding shaft portion 53 to be mounted on the bearing device 40, the side plate 56 side of the winding body 52 interferes with the gate member 34, and to avoid this interference, the protruding shaft portion 5
4 is attached to the bearing device 30, the protruding shaft portion 53 does not fit inside the bearing device 40, so in any case, the stencil printing base paper roll 50 is attached to the machine frame 1.
It is not installed on the

の製版に供される。 That is, the stencil printing base paper roll 50 is attached to the machine frame 1 only in the correct axial orientation, so that the stencil printing base paper S of the stencil printing base paper roll 50 is always in the correct front-back relationship for stencil printing. Provided for plate making.
