Abstract:
1. A liquid droplet jetting apparatus which jets liquid droplets of a liquid onto a medium, comprising: a liquid droplet-jetting head which is configured to jet the liquid droplets; a storage tank which is configured to store the liquid to be jetted by the liquid droplet-jetting head; a tube which is configured to connect the liquid droplet jetting head and the storage tank; a liquid-state detecting mechanism which is configured to be moveable along a longitudinal direction of the tube, and which is configured to output a detection signal regarding a state of the liquid contained in the tube at a plurality of positions in the longitudinal direction of the tube; and a controller which is configured to detect the state of the liquid based on a speed of a movement of the liquid-state detecting mechanism and a time period during which the detection signal, which is output by the liquid-state detecting mechanism while moving, varies across a threshold value.
