Abstract:
A nozzle inspection device includes an inspection electrode placed apart from a discharge unit with a gap therebetween, an inspection unit for inspecting the presence of a defective nozzle by discharging a fluid with respect to the inspection electrode in a state in which the electric field is generated by application of a voltage between the discharge unit and the inspection electrode, a detection unit for detecting whether the inspection unit is in a non-inspectiable state, and a gap adjustment unit for adjusting the gap by transferring either the discharge unit or the inspection electrode in a case in which the inspection unit is in the non-inspectable state.
