Patent number: 10583671Abstract: A first feeder contacts a first surface of a first sheet held in a first tray and feeds the first sheet toward a recording unit. A second feeder contacts a first surface of a second sheet held in a second tray and feeds the second sheet toward the recording unit. An inner member is disposed above a standing plate. An outer member comprises an upstream portion opposing the standing plate, and a downstream portion opposing the inner member. The inner member guides the first surface of the first sheet and the first surface of the second sheet. The standing plate guides the first surface of the second sheet. The upstream portion of the outer member guides a second surface of the second sheet, and the downstream portion guides a second surface of the first sheet and the second surface of the second sheet. The standing plate moves relative to the outer member.Type: GrantFiled: October 23, 2018Date of Patent: March 10, 2020Assignee: Brother Kogyo Kabushiki KaishaInventors: Tetsuo Asada, Kensuke Hirate, Yoshiyuki Washino

Patent number: 10414174Abstract: 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: GrantFiled: September 18, 2018Date of Patent: September 17, 2019Assignee: BROTHER KOGYO KABUSHIKI KAISHAInventors: Tetsuo Asada, Hirotaka Aoki, Satoru Nakakita, Shota Iijima, Kenji Samoto, Yuji Koga
