Abstract:
An ink jet printer, comprising:a print head that forms an image onto a recording medium by ejecting an ink; an ink container that contains the ink supplied to the print head, the ink container being provided separately from the print head; a guide rail that guides the print head in a width direction of the recording medium; a print head moving device that reciprocates the print head along the guide rail; a tube member that protrudes from a first side surface or a second side surface of the print head on an end side facing a moving direction thereof and connects the print head and the ink container over a full range of a print head moving area to supply the ink from the ink container to the print head, the tube member having elasticity; a roller that feeds the recording medium in a direction perpendicular to the guide rail, the roller being disposed near the guide rail; and a cover that covers the roller to prevent the tube member, that bends as the print head moves, from contacting the roller, wherein the cover and the guide rail are disposed along a plane substantially vertical to a direction that the tube member bends as the print head moves, and the cover and the guide rail are disposed with a distance therebetween that prevents the tube member from passing through the distance between the cover and the guide rail.
