プリンタ。 First and second coaxially arranged with an air layer in between
The ink droplets ejected from the first orifice during the printing operation are directed from the outer periphery of the air layer toward the second orifice through an air flow supplied from an air flow source to the second orifice. an ink droplet ejecting device that causes the ink droplets to fly from the second orifice and, during non-printing operations, fills the air layer with an anti-clogging liquid within the operating time of the air flow generation source to prevent clogging of the first orifice; In the inkjet printer, the air flow generation source and the ink droplet ejecting device are connected by an air supply pipe, and a spiral air supply pipe is used for the air supply pipe near the ink droplet ejecting device. An inkjet printer characterized by:
