Abstract

To provide a printing apparatus enabling its ink supplying member connected to a liquid jet head unit to be prevented from breaking when removing the liquid jet head unit mounted on a head mounting member. When removing a liquid jet head unit mounted on a head mounting member, the liquid jet head unit held by a head holding mechanism is released after an ink supplying member connected to the liquid jet head unit is separated therefrom by a pipe-installing and removing mechanism. In other words, the ink supplying member is separated from the liquid jet head unit by the pipe-installing and removing mechanism while the liquid jet head unit being held in the head mounting member by the head holding mechanism. This means that the ink supplying member is not separated from the liquid jet head unit in the improper direction and leads to preventing the ink supplying member from breaking when removing the liquid jet head unit.
