Abstract

PURPOSE:To keep the jet ink in constant viscosity at all times, and to form stable ink grains by detecting the viscosity of the ink and mixing an ink diluting liquid. CONSTITUTION:When the ink evaporating from a recovery port 210 and the ink volatilizing by evaporation 217 flow in from 208, the specific gravity of the ink in a sub-tank 205 increases gradually. When the specific gravity exceeds the specific gravity of a buoy 309, the buoy 309 rises using a stem 307 as a guide, signals are emitted when a magnet 310 rises within a functioning range of a reed switch, and a conduit 304 from a cartridge 301 for the diluting liquid and an output conduit 306 are connected. Accordingly, the inside of the sub-tank 205 is diluted gradually, and the specific gravity lowers. When the specific gravity becomes lower than the specific gravity of the buoy 309, the buoy 309 starts sinking, and the reed switch emits opening signals. A solenoid valve 305 is connected to an original condition, the ink 303 side, and a cycle returning a viscosity coefficient to normalcy is completed.
