本考案は、孔版印刷装置に係り、特に輪転式孔
版印刷装置の版胴に孔版印刷用原紙を取付ける孔
版印刷用原紙取付装置に係る。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a stencil printing device, and more particularly to a stencil printing paper mounting device for mounting a stencil printing paper onto a plate cylinder of a rotary stencil printing device.

ればならないという不便があつた。[Prior Art] A stencil printing base paper generally has a rectangular base paper body and a reinforcing paper piece stuck to the front edge thereof and having an engagement hole for attaching the base paper. It is designed to be attached around the plate cylinder with the engagement hole engaged with an engagement pin for attaching the base paper arranged along one generatrix in a part of the outer peripheral surface of the plate cylinder. . In this case, in order to prevent the front edge of the base paper from accidentally coming off the engagement pin, in the past it was common practice to make the tip of the engagement pin thicker and make it a so-called headed pin. However, with headed pins,
A slight positional shift is required between the plate cylinder and the base paper when the engagement hole passes over the head of the pin and when the engagement hole engages with the shaft of the pin. There was an inconvenience in that the position of the base paper had to be shifted relative to the plate cylinder when it was removed.

提案されている。 In view of this, the engaging pin is constructed by bending a bar with a uniform cross section into a U-shape or key shape, and the base paper has a hole in the shape that matches the cross-sectional shape of the bar. An engagement hole is provided with a cut from the edge, and when attaching the base paper to the engagement pin or removing the base paper from the engagement pin, the hole widens due to the cut, making attachment and removal easy. Moreover, it is a practical matter to ensure that the relative positional relationship between the engagement pin and the base paper does not change during engagement and during attachment or removal of the base paper.
Combination of No. 62-940 (engaging hole) and Utility Model No. 62-5345 (engaging pin) and Utility Model No. 62-941 (engaging hole)
It is proposed as a combination of and Utility Model No. 62-5346 (engaging pin).

れる。[Problems to be solved by the invention] Regarding the attachment of stencil printing paper to the plate cylinder of a rotary stencil printing device, it is necessary to ensure that it is easy to attach and remove, that the attachment condition is stable, and that the head pin is fixed. In addition to the fact that there is no deviation in the relative position between the plate cylinder and the base paper when the engagement hole engages with the shaft of the pin and when the base paper is being attached or removed, A rotary stencil printing device uses a press roller that moves close to the plate cylinder in synchronization with the rotation of the plate cylinder and presses the printing paper against the stencil printing paper attached around the plate cylinder, and a press roller that removes used base paper from the plate cylinder. Since it includes a device located very close to the plate cylinder and selectively acting on it, such as a base paper peeling claw for peeling off the base paper, the engagement pin for attaching the base paper is
It is desired that the height be as low as possible.

付手段の組合せによつて達成される。[Means for Solving the Problem] According to the present invention, the problem is solved by the plate cylinder side mounting means and the base paper side mounting means for mounting the leading edge of the stencil printing base paper on the plate cylinder of the rotary stencil printing device. In combination, the plate cylinder side attachment means includes a magnetic base paper receiving surface and a columnar pin having a substantially constant cross section projecting from the base paper receiving surface, and the base paper side attachment means is attached to the leading edge of the base paper. This is achieved by a combination of a plate cylinder side attachment means and a base paper side attachment means, which are characterized in that they include a ferromagnetic metal thin film having a hole having a shape corresponding to the cross section of the pin.

や取外しは一層容易になる。[Operations and effects of the invention] According to the above-described combination of the plate cylinder side attachment means and the base paper side attachment means, since the engagement pin is a columnar pin with a constant cross section, the engagement pin is similar to a headed pin. Needless to say, there is no misalignment in the relative position between the plate cylinder and the base paper when the mating hole engages with the shaft of the pin and when the base paper is being attached or removed. Attaching and removing the base paper from the cylinder,
This can be easily done by passing a columnar pin of a constant cross section through a hole drilled in the ferromagnetic metal thin film, and the attachment of the base paper to the plate cylinder is determined by the magnetic force of the ferromagnetic metal thin film when the pin and the engagement hole are engaged. The ferromagnetic metal thin film is held stably by adsorption to the base paper receiving surface, and the engagement created in the ferromagnetic metal thin film by the close contact of the ferromagnetic metal thin film to the base paper receiving surface due to such magnetic attraction. A small height of the pin is sufficient since the holes ensure deep engagement up to the base of the pin, thus reducing the height of the sheet attachment device protruding from the plate cylinder and thereby reducing the height of the pin. This makes it easier to attach and remove the base paper.
