PROBLEM TO BE SOLVED: To minimize the loss of paper to be generated following the stoppage of a printing operation for a short time by vibrating a transverse swinging roller at a minimum amplitude in a printing stop mode and vibrating the transverse swinging roller at a routine amplitude in a printing operation mode and increase the amplitude prior to the start of a printing operation. SOLUTION: A transverse swinging roller 15 is vibrated at a minimum amplitude in a printing stop mode and then is vibrated at a routine amplitude in a printing operation mode. In addition, this amplitude is increased prior to the start of a printing operation. This vibration is generated using a central electronic control device 8 and is transmitted to an ink kneading roller 15 as the transverse swinging roller by a drive device 41 through a power transmission device 43 for lifting the transverse swinging roller 15 and further, through a rod 47, a slider 32 which comes into contact with the interior of a slot 40, a connecting link 37 and a lever 52. The lever 56 rocks by a lever shaft 56 and the ink kneading roller 15 is moved in the axial direction. |
