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 guide rail to guide the print head, a transport roller to feed the recording medium, and a cover to prevent the tube member from contacting the roller. As the print head reciprocates in a width direction of a recording medium, the tube protruding from a surface of the print head on an end side in a moving direction thereof bends or flexes when the print head moves together with a carriage. The bending of the tube in the rearward direction is restricted by a tube band contacting the transport roller and cover. The cover and guide rail form a plane vertical to a platen at front faces of the cover and the guide. When the bending or movement of the tube is blocked or restricted by the vertical plane to a tube bending direction, the tube is not raised. Therefore, a resistance is not applied to the print head during the movement of the print head Thus, the bending or movement of the tube can be restricted without providing a special device for the ink jet printer.
