Abstract
There is disposed a sealing mechanism having a container which stores an ink liquid; an ink head which spouts the ink liquid; and an ink channel switching section which is disposed in an ink channel connecting the container to the ink head and which switches the ink channel to a sealed state or an opened state, wherein the ink liquid flowing into the ink head from the container is quickly replaced with air (bubble) flowing through the container from the ink head during the switching of the ink channel to the opened state from the sealing state.
