PROBLEM TO BE SOLVED: To prevent floating-up of a tube connecting an inkjet head and an ink cartridge, and entangling of the tubes. SOLUTION: The flexible four tubes 6 for connecting four connecting ports 3c of the inkjet heads 3 arrayed along a paper sheet feed direction in parallel to a horizontal plane, to the ink cartridge 7, are fixed under a vertical-directionally arrayed state, in a fixing part 6a in the midway thereof. A tube guide 8 is arranged in an outer circumferential side, of the tube 6, in a bending direction of the tube 6 in top view. Ribs 15 projected from an opposed face 8a, and tapered to make a vertical-directional length shorter toward its tip, are formed individually corresponding to the four tubes 6, on the opposed face 8a opposed to the tubes 6 of the tube guide 8. The ribs 15 are constituted to project one arranged in a lower side more greatly from the opposed face 8a than one arranged in an upper side. COPYRIGHT: (C)2010,JPO&INPIT |
