Patent number: 8684510Abstract: A drying device includes a drying unit configured to carry out a drying process on a recording medium by blowing heated air from a discharge port formed at a location partway along the conveyance path of the recording medium as the medium is conveyed from the upstream side to the downstream side in the conveyance direction. A drying zone is disposed on the downstream side of the drying unit in the conveyance direction over the front face of the recording medium so that the air blown from the discharge port is retained in the drying zone. An upper surface of the drying zone is defined by an extended surface portion of an outer surface of a housing of the drying unit, the extended surface portion extending from the discharge port toward the downstream side in the conveyance direction to cover the conveyance path from above.Type: GrantFiled: March 4, 2011Date of Patent: April 1, 2014Assignee: Seiko Epson CorporationInventors: Kazuko Miyamoto, Satoru Shiohara, Hiroshi Mikyazawa
