It has been found that the change in the difference α is the cause of the jerky pulsation of the roll matrix 11.

The center of rotation of the (motor driving cylinder 30) and the center of rotation of the internal gear 29 (the driven rotation cylinder 31) on the power output side are both the axis of the support shaft 14, and the axis of the common support shaft 14 Is always directly proportional to the number of teeth of the internal gears 28 and 29 that sequentially pass through the meshing point of the internal gears 28 and 29 with the external gear 27. Since there is no deviation between the rotation centers, the driven rotary cylinder 31 on the output side has no pulsation (rattle), and the roll base 11 swings smoothly in the axial direction. As a result, the ink film or the water film adhering to the peripheral surface of the printing roll that is driven to rotate in contact with the oscillating printing roll 36 of the present invention is stroked by the oscillating printing roll 36 in the axial direction. An ink film or water film having a smooth and uniform thickness is obtained.
