Patent number: 11262684Abstract: A first transport unit transports, along a first path, a sheet transported from an image forming unit. A second transport unit transports the sheet along a second transport path branched from a junction with the first transport path. A first cover, when open, holds the sheet transported to an exterior of a housing and, when closed, partially constitutes the second transport unit. A flap is disposed at the junction and, when at a first position, blocks the second transport path and guides the sheet along the first transport path and, when at a second position, blocks the first transport path and guides the sheet along the second transport path. A drive unit moves the flap between the first position and the second position. A moving mechanism moves away from the flap in response to closing of the first cover, and pushes and moves the flap to the second position.Type: GrantFiled: December 23, 2019Date of Patent: March 1, 2022Assignee: BROTHER KOGYO KABUSHIKI KAISHAInventors: Yusuke Ikegami, Kazuya Kamikawa

Patent number: 11099514Abstract: An image forming apparatus includes a first transport unit, a second transport unit, a cover, a flap, a drive unit for moving the flap, a first sensor for detecting opening and closing of the cover, a second sensor for detecting a position of a sheet, and a controller. The controller switches the drive unit to move the flap to the second position, upon determining it is necessary to move the flap to the second position, subsequent to determining that the cover is opened based on a detection result by the first sensor. The controller switches the drive unit to move the flap from the second position to the first position, upon determining, based on a detection result by the second sensor, that a leading edge of the sheet reaches a position downstream, in a sheet transport direction, of a swing end portion of the flap at the second position.Type: GrantFiled: December 23, 2019Date of Patent: August 24, 2021Assignee: Brother Kogyo Kabushiki KaishaInventors: Kazuya Kamikawa, Yusuke Ikegami

Patent number: 10494210Abstract: An image forming apparatus having a duplex conveyer is provided. The duplex conveyer includes a first roller and a second roller arranged in an area closer to a first side surface of a body rather than a second side surface to align along a widthwise direction, a third roller and a fourth roller arranged to contact the first roller and the second roller respectively, an upper guide supporting the first roller and the second roller, and a lower guide arranged to face the upper guide at a position lower than the upper guide. The upper guide has a recessed portion at a position between the first roller and the second roller. The recessed portion recesses from an end of the upper guide on a side facing the first side surface toward the second side surface beyond an axis of the first roller.Type: GrantFiled: January 24, 2018Date of Patent: December 3, 2019Assignee: Brother Kogyo Kabushiki KaishaInventors: Kazuya Kamikawa, Shoichiro Nishimura
