1項に記載の謄写輪転機のプレスローラ装置。[Scope of claims for utility model registration] (1) A press roller disposed below the plate cylinder,
A pair of left and right press roller arms rotatably support this press roller and are biased to rotate by a spring so that the press roller is pressed against the plate cylinder, and a rotation support shaft of this press roller arm is used during printing. In a press roller device of a rotary copying machine, which is equipped with a press roller contact/separation mechanism that rotates the press roller so that the press roller is pressed against the plate cylinder and separated from the plate cylinder when not printing, a hole is formed in at least one of the left and right press roller arms. The arm pivot support includes a keyhole in which a narrow pilot hole and a wide upper hole are connected, and an arm stay that has a removable latch claw that is engaged with the pilot hole through the upper hole of the keyhole. At the same time as fixing the press roller arm to the shaft, insert either the left or right press roller arm with the keyhole into the rotation support shaft so that it can rotate around the axis and move in the axial direction. Push down and rotate by hand against the spring force and slide in the axial direction to disengage the keyhole of the press roller arm from the arm stay and remove the roller bearing part of the arm from the end of the roller shaft. A press roller device for a rotary copying machine, characterized in that the press roller can be easily removed. (2) The left and right press roller arms are fitted into the rotation support shaft so that they can rotate around their axes, and the left and right press roller arms are both provided with keyholes. A press roller device for a rotary copying machine according to claim 1, wherein a pair of left and right arm stays that engage with a keyhole are fixed to both ends of an arm rotation support shaft. (3) A cam arm in which the press roller contact/separation mechanism is fixed at a position on the arm side where the arm rotation support shaft does not move, and the press roller is pressed against the plate cylinder during printing and is separated from the plate cylinder when not printing. A press roller device for a rotary copying machine according to claim 1, characterized in that the press roller device is comprised of a rotary cam that is operated to perform the following actions.
