Abstract: A printing apparatus includes a carriage, ink tanks, ink tubes, and a first tube holder. The carriage reciprocates in a predetermined direction with respect to a recording medium and has recording heads ejecting ink to the recording medium. The ink tanks are arranged outside the carriage and are configured to contain ink. The ink tubes connect the ink tanks and the recording heads to each other to supply the ink contained in the ink tanks to the recording heads, and the ink tubes undergo follow-up deformation along with reciprocating movement of the carriage. The first tube holder is rotatably supported with respect to the carriage and holds the ink tubes.

Abstract: An ink cartridge includes a main body, a head part, a first hole, a label, and a second hole. The main body stores ink. The head part is provided on the main body and has a plurality of nozzles for ejecting ink. The first hole has a tapered shape which narrows from an outer side toward an inner side of the main body, and a needle for supplying ink to the main body is inserted into the first hole. The label in a film shape is attached to the main body. The second hole is provided at the label and overlaps the first hole in a plan view of the label. The second hole guides the needle to the first hole when the needle is inserted.
