Abstract
Disclosed is an ink supply mechanism comprising a first ink tank for storing ink; a joint portion connected to the first ink tank; and a second ink tank disposed to be movable to the first ink tank, being provided with a connection portion connected to the joint portion in order to make ink supply from the first ink tank possible, wherein the joint portion is movable between a connected position where the connection portion is connected thereto and a disconnected position where the connection portion is not connected thereto, and a cap member for sealing a region between the connection portion and the joint portion at both the connected position and the disconnected position is provided on the joint portion. Therefore, invasion of foreign materials into an ink path can be prevented when the joint portion and the second ink tank are connected to each other, and adherence of ink in the joint portion can also be prevented.
