Abstract
A carriage accommodates a plurality of ink tanks including a first ink tank and second ink tanks, all being detachably attached in the carriage. Each ink tank holds ink of a color different from others. The carriage further includes a plurality of ink entrances provided therein, each ink entrance receiving ink from a corresponding ink tank. The first ink tank is generally L-shaped and has an ink capacity larger than any of the second ink tanks. The first ink tank holds, for example, black ink therein. The first ink tank and the second ink tanks are attached in the carriage in such a fashion that the first ink tank holds the second tanks in a space defined by the L-shape. The first and second ink tanks are formed with engagement portions which engage each other in a complementary relation when the ink tanks have been assembled in the carriage. The first ink tank has at least one ink exit and may further include caps. The ink exit and the caps are formed in alignment with the ink entrances in the carriage.
