Abstract

PURPOSE:To keep foam from flowing into an ink room and improve stability and reliability by forming grooves in an ink supply-preparation room deeper than the grooves at the other parts. CONSTITUTION:The depth 14 of the groove in an ink supply-preparation is made deeper than the depth 15 of the groove at other parts. Also, an opening hole 13 to the atmosphere is set. The above structure prevents the flowing of foam into the ink room if ink mixed with foam flows into the ink supply-preparation room 5, since the groove to the ink room 6 is shallow by one stage. When foam flows in in great amount, it escapes from the opening hole 13 rather than flows into the ink room with a shallow groove.
