Discharge inspection apparatus and discharge inspection method
Abstract:
A discharge inspection apparatus includes: a first electrode for detection which faces a nozzle, that discharges liquid of a first potential, at a predetermined interval and has a second potential different from the first potential; a second electrode for detection which faces a nozzle, that discharges the liquid of the first potential, at a predetermined interval and has the second potential; an inspection section which inspects whether or not liquid is discharged from the nozzle on the basis of electrical changes which occur at the first electrode for detection and the second electrode for detection due to the discharging of the liquid of the first potential from the nozzle; a first insulating receiving section which holds the first electrode for detection; and a second insulating receiving section which holds the second electrode for detection and is disposed with a space interposed between the second receiving section and the first receiving section.
