Abstract

PURPOSE:To increase an internal pressure of a tank to pressurize liquid of a recording medium and to eliminate instability in discharging of the medium liquid due to blocking of a nozzle or the like by a method wherein a pressurizing device of a special constitution is connected to a discharging orifice through the storage tank of the liquid of the recording medium. CONSTITUTION:A pressurizing device 5 having an air reserving portion 8 pinched by a pair of ball valves 61, 62 is connected to a discharging orifice 1 through a storage tank of liquid of a recording medium. A pressurizing portion 20 of the ball valve 61 is pressurized and outside air is flowed into the air reserving portion 8 through an air flowing portion produced between the valve 61 and an elastic covering film 7. Successively, the pressurizing is stopped and the storage portion 8 is shut off from outside, thereafter, a pressurizing portion 22 of the ball valve 62 and an air storing and pressurizing portion 21 are pressurized to force the air into the tank 4. Thereby, the liquid of the recording medium in the tank 4 is pressurized to discharge air bubbles or blocking materials in the nozzle 2 into open air through the orifice 1.
