PURPOSE:To perform a stable printing by supplying the optimum quantity of ink to needles by a method wherein, a ink tank is communicated with a slit provid- ed with the tip end of the needles through an ink passage having a form of groove. CONSTITUTION:An ink 18 in an ink tank 19 concentrates into a slit 24 only through an ink passage 25, so that an ink flowing to a slit 24 through an ink passage 25 having a form of groove is restricted to a minimum. Therefore even if there is an error in accuracy of machining and a fluctuation of viscosity of ink, allowance to these is high and always a predetermined or an approximate quantity of ink 18 concentrates to a slit 24, so that a supply of ink 18 to the terminal of needles 13 is constant and stable printing is performed. |
