PURPOSE:To ensure printing of a correct gradation at a high speed CONSTITUTION:Ink 34 is guided into a quantitative liquid chamber 8 in a quantifying portion through a supply channel 15 from an ink tank. A piezoelectric device 11 deforms, extending upward, when voltage is applied. But since the upper side is fixed to a piezoelectric device support 5, the device extends downward, pushing a piston 12 downward and reducing the cubic capacity of the liquid chamber 8, and the ink 34 of an amount equal to the decrease, that is, quantified ink 34 goes out to the liquid channel 14. The quantified ink 34 is mixed with a transparent solvent 34 discharged from a base 1. |
