Abstract:
1. A liquid-droplet jetting apparatus which jets a liquid in a liquid-droplet state, the liquid-droplet jetting apparatus comprising: a channel unit comprising: a jetting nozzle comprising a plurality of individual jetting nozzles; a jetting channel communicating with the jetting nozzle; a recovery nozzle comprising a plurality of individual recovery nozzles; a recovery channel communicating with the recovery nozzle; and a liquid-droplet jetting surface in which a plurality of individual jetting ports and a plurality of individual recovery ports are formed adjacently as openings of the plurality of individual jetting nozzles and openings of the plurality of individual recovery nozzles, respectively; a jetting-pressure applying mechanism which applies jetting pressure to the liquid in the jetting channel; a cap which detachably covers both of the jetting port of the jetting nozzle and the recovery port of the recovery nozzle; and a purge pressure applying mechanism which causes the liquid in the jetting channel to flow to the recovery channel when the cap covers both of the jetting port and the recovery port; wherein the liquid is flowed out from the jetting port to be recovered from the recovery port to the recovery channel by the purge pressure applying mechanism; wherein the individual jetting ports are aligned in a predetermined direction in the liquid-droplet jetting surface; and each of the individual recovery ports is arranged aligned in a row and between the individual jetting ports.
