開発されていなかった。As an apparatus for producing the above-mentioned prepress proof, an impression cylinder having an image forming material attached thereto and a transfer cylinder having an image receiving member attached thereto are arranged so that the photosensitive layer of the image forming material and the image receiving member face each other. An apparatus has been generally proposed in which both cylinders are brought into contact with each other and the image formed on the photosensitive layer is transferred to an image receptor at a nip between the cylinders. In such a device, as a device for attaching an image receptor such as paper on a transfer cylinder, a device that can easily attach and detach a sheet-like object such as a conventional sheet-like object and can hold it uniformly over the entire width has been developed. It has been strongly sought after, but has not yet been developed.

ンプによって保持してもよい。FIG. 1 shows an example in which the pinion gear 9 is rotated by an L-shaped lever 14 provided with a rack gear 13 that meshes with the pinion gear 9. L-shaped lever 14 is a fulcrum 15
Is rotatably attached to the end surface of the cylindrical body 1, and a cam 16 is brought into contact with the end of the L-shaped lever 14, and the L-shaped lever 14 is rotated by the cam 16. Further, elastic means having both ends fixed to the end face of the cylindrical body 1 and the L-shaped lever 14 such as a coil spring 19 is provided, and the cam side end portion of the L-shaped lever 14 is pulled upward, whereby the pressing-side sheet receiving member is received. Apply force in the direction to close the part 5. FIG. 2 is an example in which the pinion gear 9 is rotated by the gears 17 and 18 to open and close the pressing side sheet receiving portion 5. The gear 18 is driven by means capable of controlling rotation / stop at an arbitrary position, for example, a stepping motor (not shown), or the gear 18
It is preferable to provide a lock mechanism (not shown) such as a ratchet to the gear so that the gear can be fixed at a desired position. In the present invention, both ends of the sheet-shaped material may be held by the sheet-shaped material holding device of the present invention, and in some cases, only one end is held by the sheet-shaped material holding device of the present invention, The other end may be held by another holding device, such as a clamp.
