Patent number: 9013769Abstract: In a conveyor of an image-reading device, a first path is defined by a path from the upper path to the lower path via the curved path. A second path is defined by a path from the upper path to the extension path. A first reading unit is disposed on the upper path and reads the first surface while the original sheet is on the upper path. A second reading unit is disposed on the upper path and reads the second surface while the original sheet is on the upper path. A third reading unit is disposed on the lower path and reads the second surface while the original sheet is on the lower path. When the reading section reads the original sheet, the conveyor conveys the original sheet through the first path or the second path.Type: GrantFiled: October 6, 2014Date of Patent: April 21, 2015Assignee: Brother Kogyo Kabushiki KaishaInventors: Yoshinori Osakabe, Atsushi Yokochi
