Publication number: 20200108634Abstract: An image recording device is provided, having a recording unit configured to record an image on a sheet, and a tray disposed below the recording unit. The tray includes a sheet holding surface configured to hold the sheet. Additionally, the image recording device includes a sheet feeder disposed between the recording unit and the tray. The sheet feeder includes a roller for feeding the sheet from the tray. The roller is configured to move between a first roller position in which the roller contacts the sheet holding surface of the tray and a second roller position in which the roller is separated from the sheet holding surface. A return guide, disposed between the recording unit and the sheet feeder, defines a second conveying path to guide the sheet having an image recorded on one side thereof back to the feed guide. The return guide has a first opening configured to accommodate the roller of the sheet feeder when the roller is in the second roller position.Type: ApplicationFiled: August 19, 2019Publication date: April 9, 2020Inventors: Tetsuo ASADA, Hirotaka AOKI, Satoru NAKAKITA, Shota IIJIMA, Kenji SAMOTO, Yuji KOGA
