PROBLEM TO BE SOLVED: To provide a direct liquid type coating tool having a backflow prevention mechanism and an on-off valve capable of widening ink engineering.SOLUTION: In a direct liquid type coating tool, a member for applying capillary force to a coating body is arranged, and an on-off valve is disposed on an ink passage between the coating body and a storage tube. The ink passage between the coating body and the on-off valve is sealed, and the on-off valve has such a function that it opens when ink pressure on the coating body side is more negative pressure than that of the storage tube side. |
