ABSTRACT:
An ink jet printer includes an ink container supplying ink through a tube member to a separate print head to form an image. The ink jet printer also includes a supporting portion that supports the tube member. As the print head reciprocates in a width direction of a recording medium, the tube member flexes as the print head mounted on a carriage moves. The tube protruding from the print head is inclined at approximately 30 degrees with respect to a moving direction of the print head, toward the supporting portion. When the tube is pulled toward the supporting portion, resistance to the movement of the print head can be restricted. When the tube bends or curves between the supporting portion and the print head, the tube can be moved smoothly toward the supporting portion. Thus, when the print head reciprocates, the tube can flex smoothly and the resistance applied to the print head by the tube can be restricted, allowing proper ink supply to the print head.
