PROBLEM TO BE SOLVED: To solve the problem that operations up to a printing head replacement are complicated and therefore an error can easily occur at the time of replacing the printing head, and ink leakage is brought about in the worst case. SOLUTION: A configuration is set which can simplify the time and effort required for the printing head replacement. Specifically, at the time of separating a plurality of joints which couple channels between the printing head side and the ink supply device side, the configuration enables the joints to be separated with a time lag. Moreover, the joints are arranged at a position where a head difference is generated between an ink tank and the printing head at the time when the ink channel of one side is separated.
