Abstract
A meniscus of applying fluid is controlled by applying a voltage to a discharge-nozzle side electrode and a counter electrode placed downstream of the discharge nozzle and by increasing or decreasing fluid pressure inside a pump chamber with use of a mechanism for rotational motion or rectilinear motion.
Claims11
A fluid applying apparatus comprising:
- a housing having a suction port for sucking an applying fluid and a discharge nozzle at an end of the housing, the discharge nozzle defining a discharge port for discharging the applying fluid;
- a moving member which forms a pump chamber for the applying fluid in combination with the housing, the moving member being rotationally or rectilinearly movable relative to the housing;
- a moving-member driving device for driving the moving member to make the housing perform the rotational motion or rectilinear motion so that applying-fluid pressure inside the pump chamber is increased or reduced;
- a housing-side electrode provided at an outer peripheral portion of the discharge nozzle at the end of the housing;
- and
- a power supply for applying a voltage to the housing-side electrode.
