Patent ID: 7963627

Claim:
A liquid droplet jetting-inspection apparatus which inspects jetting of a liquid droplet-jetting apparatus having a nozzle through which liquid droplets of a liquid are jetted and causing change in pressure of the liquid based on a predetermined driving signal to jet the liquid droplets from the nozzles, the liquid droplet jetting-inspection apparatus including: a pressurized liquid supply mechanism which pressurizes the liquid, and supplies the pressurized liquid to the liquid droplet-jetting apparatus to make the liquid be discharged continuously from the nozzle; and a liquid droplet-jetting control mechanism which applies the driving signal at a predetermined time interval to the liquid droplet-jetting apparatus, during which the liquid is continuously discharged from the nozzle; and a light emitting mechanism which includes a light source, and which makes the light source emit light at a time interval that is an integer multiply of the predetermined time interval.
