Abstract: An ink jet recording device comprises a main body equipped with an ink container, an ink supply pump ink, an ink recovery pump, and a control unit. A printing head equipped with a nozzle emits ink supplied from the main body as ink particles. An electrification electrode electrifies the ink particles and a deflection electrode deflects the electrified ink particles. A gutter collects ink particles which are not used for printing. An exhaust circulation path connects the ink container and the gutter. The gutter comprises two members of an ink flow path block in which ink flows and an exhaust flow path block in which exhaust solvent vapor flows.

Abstract: An ink jet recording device, comprises: a main body equipped with an ink container which accumulate ink, an ink supply pump which supplies the ink, an ink recovery pump which recovers the ink, and a control unit; a printing head equipped with a nozzle which jets the ink supplied from the main body as ink particles, an electrification electrode which electrifies the ink particles, a deflection electrode which deflects the electrified ink particles, and a gutter which collects ink particles which are not used for printing; and a cable in which an ink supply flow path for supplying the ink from the main body to the printing head, an ink recovery flow path for returning the ink particles collected by the gutter into the ink container, an exhaust circulation path which connects the ink container and the gutter, and various signal lines for connecting the control unit and the printing head, are arranged.

Abstract: An inkjet recording apparatus includes a main body and a print head. The main body includes a mechanical portion and a control portion. The mechanical portion includes a pump that pressurizes or draws a liquid(s), such as an ink and/or a solvent, and a solenoid valve that switches between flow channels guiding the liquid to flow therethrough. The control portion controls respective operations including printing and running and stopping of the inkjet recording apparatus. The print head includes a nozzle that atomizes the ink pressure fed from the main body into ink droplets, a charging electrode that electrically charges the ink droplets, a deflecting electrode that forms an electric field that deflects the charged ink droplets, and a gutter that collects the ink unused for printing. The nozzle includes a surface-treated layer that repels the ink to a portion where the ink is supplied.
