Ink jet recording device

摘要

An ink jet recording device, comprises: a main body (600) equipped with an ink container (2) which accumulate ink (1), an ink supply pump (3) which supplies the ink (1), an ink recovery pump (10) which recovers the ink, and a control unit; a printing head (610) equipped with a nozzle (4) which jets the ink (1) supplied from the main body (600) as ink particles (5), an electrification electrode (6) which electrifies the ink particles (5), a deflection electrode (7) which deflects the electrified ink particles (5), and a gutter (9) which collects ink particles (5) which are not used for printing; and a cable (620) in which an ink supply flow path for supplying the ink (1) from the main body (600) to the printing head (610), an ink recovery flow path for returning the ink particles (5) collected by the gutter (9) into the ink container (2), an exhaust circulation path (12) which connects the ink container (2) and the gutter (9), and various signal lines for connecting the control unit and the printing head (610), are arranged. The gutter (9) comprises two members of an ink flow path block (13) in which ink flows, and exhaust flow path block (14) in which exhaust solvent vapor (11) flows.
