PURPOSE:To miniaturize the equipment by mounting ink circulation systems on a carriage in such a manner that the ink circulation systems are arranged on two separate substrates while an ink passage is formed by separate holes of the substrates. CONSTITUTION:A carriage 10 is composed of substratesI, II and III on which a complete set of ink circulation systems comprising an ink cartridge 14, an ink pressure pump 15, a filter 22, a valve 25, an ink reservior 20 and the like is arranged. An ink passage is formed by holes 30 separately made on the substrates. Thus, an assembly work is done simply as follows: these ink circulation system units are assembled on separate substrates and then, the substrates are laminated with connecting screws. |
