少する。As is apparent from the above description, in the present invention, the cylinders are arranged between the upstream cylinder and the downstream cylinder in the paper transport direction with their circumferential surfaces facing each other. And a paper transport cylinder and a reversing mechanism that reverses the paper that has passed through the contact point between the paper transport cylinder and the upstream cylinder and is attached to the upstream cylinder and transfers it to the downstream cylinder. In a sheet-fed rotary printing press with a mechanism, a paper tail holding member that is provided in a reversing mechanism and holds a paper tail is rotatably supported by a paper transport cylinder and is retractable with respect to a peripheral surface of the paper transport cylinder. By providing a rotating device for rotating the paper tail holding member and a moving device for moving the paper tail holding member so that the paper tail holding member moves in and out with respect to the peripheral surface of the paper transport cylinder, the paper tail can be turned over when the paper is reversed. The paper edge holding surface of the holding member is the direction in which the paper is peeled from the peripheral surface of the upstream drum. Since it is almost parallel to the tangential direction of the upstream drum, the paper tail may be peeled or slipped from the paper holding surface of the paper tail holding member due to the tension of the paper that adheres to the peripheral surface of the upstream drum. In addition, the quality of printed matter is improved, accidents such as paper drop are eliminated, and the amount of waste paper is reduced.
