Abstract
In a connecting device for connecting an ink supply source and an ink jet head, a connecting member 16 connected with an ink cartridge 7 is provided with a needle member 17, a first and second ink guide paths 19 and 20, which communicate with one another, a filter 21 is disposed at a slant with the direction A of ink flowing in the first ink guide path 19. The velocity and the negative pressure of ink flow flowing along a filter face 21A of the filter 21 increase as the ink flows downward, and the velocity and the negative pressure of ink flow at a filter face 21B are contrary thereto. By utilizing this property, air bubble K generated at an ink supply operation to the ink jet head H is allowed to rapidly move downward along the filter face 21A, passed through the filter 21, and led to a second ink guide path 20.
