Patent number: 9592674Abstract: A liquid droplet ejecting apparatus includes a transport unit configured to transport a medium in a transport direction, a support configured to support the medium transported by the transport unit, a liquid droplet ejecting portion configured to eject liquid droplets to the medium supported by the support, a carriage configured to reciprocate in a scanning direction intersecting the transport direction while holding the liquid droplet ejecting portion, and an air flow generator configured to create an air flow in an area over the support. The air flow generator limits creation of the air flow when the liquid droplet ejecting portion faces the medium in an ejection direction and allows the creation of the air flow when the liquid droplet ejecting portion does not face the medium in the ejection direction, due to movement of the carriage in the scanning direction.Type: GrantFiled: January 19, 2016Date of Patent: March 14, 2017Assignee: Seiko Epson CorporationInventors: Katsuya Asamoto, Tsuneyuki Sasaki, Shuichiro Nakano
