Rotation of the drive motor is transmitted to the paper feed cylinder gear and the paper discharge gear through the impression cylinder gear. The rotation force of the impression cylinder gear is also transmitted to, in the order of, the blanket cylinder gear, the plate cylinder gear, and the rotation and reciprocation mechanisms. Driving connection between the paper feed cylinder gear and the paper feed cylinder is selectively disconnected by the first clutch. Driving connection between the paper discharge gear and the paper discharge portion is selectively disconnected by the second clutch. Driving connection between the plate cylinder gear and the ink reciprocation roller is selectively disconnected by the third and fourth clutch.
