Patent number: 11633958Abstract: A liquid discharge apparatus includes a body and a carriage disposed inside the body. A head is mounted on the carriage. The head discharges ink onto a recording medium and generates ink mist. An ink mist collector includes a fan that generates an air current that circulates in an air flow direction inside the body. A filter collects the ink mist generated by the head. At least one duct adjusts the air flow direction. An encoder is mounted on the carriage. The encoder is disposed downstream from the fan and disposed upstream from the head in the air flow direction.Type: GrantFiled: January 25, 2021Date of Patent: April 25, 2023Assignee: RICOH COMPANY, LTD.Inventors: Tsuguyori Kemma, Kazuyoshi Matsumoto, Satoshi Ueno, Yuzo Obata, Kazuyoshi Kondo
