Ink jet printer with pressure fluctuation damping device

摘要

An ink jet printer, comprising a housing (1); a carriage (9; 3') which is movable in the housing relative thereto; an ink jet recording head (21) which is mounted on the carriage and which has a plurality of ink supply channels; a damping device (13; 101) which is mounted on the carriage and which includes a plurality of damping chambers (27; 113) corresponding to the ink supply channels, respectively; an ink-tank supporting portion (5e) which is provided in the housing and which supports a plurality of ink tanks (5a-5d); and a plurality of ink supply tubes (14; 14') each of which supplies an ink from a corresponding one of the ink tanks to a corresponding one of the ink supply channels of the ink jet recording head via a corresponding one of the ink supply tubes and a corresponding one of the damping chambers. The damping device further includes a primary partition wall (35; 115) which separates at least one first damping chamber (27a; 113a) of the damping chambers, from at least one second damping chamber (27b, 27c, 27d; 113b, 113c, 113d) of the damping chambers. <IMAGE>
