ABSTRACT:
The discharge determination device which determines discharge status in a droplet discharge apparatus comprising: a nozzle which discharges a droplet of liquid; a pressure chamber which is connected to the nozzle and stores the liquid to be discharged from the nozzle; a supply flow channel which supplies the liquid to the pressure chamber and is connected to the pressure chamber; and an actuator which causes the droplet to be discharged from the nozzle by causing at least a portion of the pressure chamber to deform and thereby applies a pressure change to the liquid inside the pressure chamber, the discharge determination device comprises: a pressure determination device which is disposed inside the pressure chamber and includes a film member forming a portion of a face constituting the pressure chamber, the film member being displaceable in accordance with pressure change in the liquid inside the pressure chamber, the pressure determination device outputting a determination signal in accordance with displacement of the film member; and a discharge status judging device which judges the discharge status of the nozzle according to the determination signal obtained from the pressure determination device in accordance with driving of the actuator.
