いては、係止突起２の先端部に係止部を持たない
ため、製版原紙４をシリンダ１より容易に取り外
すことができる。 The operation of such a mechanism will be explained below. Since the locking protrusion 2 does not have a locking portion at its tip, it can be easily inserted into the elongated hole 5 of the edge paper 3, and the plate-making base paper 4 can be easily attached to the cylinder 1. Furthermore, when the mimeograph machine is in operation, the printing paper 4 and the edge paper 3 are rotated in the opposite direction to the rotation direction of the cylinder 1 due to printing paper (not shown) and rotating rollers that transfer ink through the printing paper 4 onto the printing paper. However, since the locking protrusion 2 of the present invention has its tip 2a inclined in the direction of rotation of the cylinder 1, this load is applied in a direction that promotes the locking action of the locking protrusion 2. to work. Therefore, when the long hole 5 is not fully inserted into the locking protrusion 2 at the time of starting the mimeograph printing machine (if it is not sufficiently locked)
Even in this case, as the plate-making base paper 4 is sufficiently locked during operation, there is no fear that the plate-making base paper 4 will be peeled off from the cylinder 1. However, at the end of printing, the plate-making base paper 4 can be easily removed from the cylinder 1 because the locking protrusion 2 does not have a locking portion at its tip.

のである。 FIG. 3 shows a second embodiment of the locking protrusion according to the present invention, and this locking protrusion 6 has a lower end 6b at the center in the width direction of the locking protrusion 2 shown in FIG. A notch 7 is provided which is substantially flush with the outer peripheral surface.

Although the number is set to be the same as the number of locking protrusions 2 and 6, the number may be larger than this. Further, in the first embodiment, the shape of the locking protrusion is a flat plate having a width in the axial direction of the cylinder 1, but it may be a simple rod shape or may be bent into an inverted dogleg shape.
