PROBLEM TO BE SOLVED: To shorten the cleaning time by switching one cleaning liquid supply means to cleaning of a blade and cleaning of a bank of ink transfer rollers with switching means. SOLUTION: In an initiation state, i.e., a state where a second cleaning nozzle 30 is directed to a blade 21, cleaning liquid 27 is spouted intermittently to the blade 21 from the second cleaning nozzle 30 in predetermined times. In the next place, the rod 34a of a first air cylinder 34 is forwarded so as to direct the second cleaning nozzle 30 in the direction of a distributing roller 13. By keeping this state, cleaning liquid 27 is spouted on the peripheral surface of distributing rollers 15, 16 from cleaning liquid 27 and, at the same time, cleaning liquid 27 is spouted intermittently on the peripheral surface of the distributing roller 13 from the second cleaning nozzle 30. Cleaning liquid 27 spouted on the peripheral surface of the distributing rollers 15, 16 transfers on each rotating roller of an ink device 3 to then be collected in a cleaning bath 20 as a waste liquid of ink. At this time, the blade 21 is cleaned in advance, so that a waste liquid of ink never flows in the downstream side of the blade 21. |
