Abstract: A droplet jetting apparatus includes: a nozzle that ejects a jet of liquid droplets; a detector that detects a hand or an object in a flight path of liquid droplets from the nozzle; a pump including a suction portion for suction of liquid, and a discharge portion which is connected to the nozzle and discharges the liquid which has been sucked into the suction portion; a driver which by rotation of a cam, sucks liquid into the pump and discharges the liquid in a compressed state; and controller which actuates the driver. When the detector detects the hand or object, the controller actuates the pump by rotation of the cam, and ejects a jet of liquid in droplet form from the nozzle.
