Abstract
An ink jet printer uses an ink tank storing ink to be supplied to a print head, an ink tube, an ink chamber mounted on a carriage to store ink to be supplied from the ink tank to the print head, and a connecting member that includes an ink outflow port connected to the ink chamber and an ink inflow port where ink flows from the ink tube. At an intersection of the ink inflow port and the ink outflow port, a direction of a flow of ink from the ink inflow port is changed. Further at the intersection, a cushion is provided to absorb pressure waves generated in the ink tube on an extended line in an initial direction where ink flows in the ink passage over the intersection.
